在第一结合部311被收容在夹具保持部4内部的状态下，若第一可动臂31进一步向开闭方向B的下侧B2转动，第一结合部311就会与夹具保持部4的内周面抵接，发生弹性变形而被卡止在夹具保持部4的内部，从而被锁定。另外，在第二结合部321被收容在夹具保持部4内部的状态下，若第二可动臂32进一步向开闭方向B的上侧B1转动，第二结合部321就会与夹具保持部4的内周面抵接，发生弹性变形而被卡止在夹具保持部4的内部，从而被锁定。由此，保持第一可动臂31及第二可动臂32相对于固定臂2的闭合状态。即，夹具保持部4能够锁定第一可动臂31和所述第二可动臂32的闭合状态。需要说明的是，夹具保持部4可以先将第一结合部311及第二结合部321中的任意一方先行锁定。In the state where the first coupling portion 311 is accommodated inside the jig holding portion 4 , if the first movable arm 31 is further rotated to the lower side B2 in the opening and closing direction B, the first coupling portion 311 will be in contact with the side of the jig holding portion 4 . The inner peripheral surface abuts, elastically deforms, and is locked inside the clip holding portion 4 to be locked. In addition, in the state where the second coupling portion 321 is accommodated inside the jig holding portion 4, if the second movable arm 32 is further rotated to the upper side B1 in the opening and closing direction B, the second coupling portion 321 will be in contact with the jig holding portion. 4 abuts against the inner peripheral surface, elastically deforms, and is locked inside the clip holding portion 4 to be locked. Thus, the closed state of the first movable arm 31 and the second movable arm 32 relative to the fixed arm 2 is maintained. That is, the jig holder 4 can lock the closed state of the first movable arm 31 and the second movable arm 32 . It should be noted that the clip holder 4 may first lock either one of the first coupling portion 311 and the second coupling portion 321 .

如图11及图12所示，第二外壁部303沿着上下方向B从基部301朝下侧B2延伸。第二外壁部303被设置在止动件300的右侧C2。第二外壁部303在左侧C1具备侧面303a。侧面303a与第一操作部主体811的第一右表面814b的形状匹配地形成，如图12所示，与第一右表面814b抵接。As shown in FIGS. 11 and 12 , the second outer wall portion 303 extends along the vertical direction B from the base portion 301 toward the lower side B2 . The second outer wall portion 303 is provided on the right side C2 of the stopper 300 . The second outer wall portion 303 has a side surface 303a on the left side C1. The side surface 303a is formed to match the shape of the first right surface 814b of the first operation unit main body 811, and abuts against the first right surface 814b as shown in FIG. 12 .
如图11及图12所示，中壁部304沿着上下方向B从基部301朝下侧B2延伸，被设置在第一外壁部302和第二外壁部303之间。中壁部304具有与第一滑动沟815的第一滑动面815a大致相同的形状，能行向第一滑动沟815插入。As shown in FIGS. 11 and 12 , the middle wall portion 304 extends from the base portion 301 toward the lower side B2 along the vertical direction B, and is provided between the first outer wall portion 302 and the second outer wall portion 303 . The middle wall portion 304 has substantially the same shape as the first sliding surface 815 a of the first sliding groove 815 , and can be inserted into the first sliding groove 815 .
如图11及图12所示，第一狭缝部305设置在止动件300的下侧B2，是形成在第一外壁部302和中壁部304之间的槽。第一狭缝部305配置在止动件300的左侧C1。As shown in FIGS. 11 and 12 , the first slit portion 305 is provided on the lower side B2 of the stopper 300 and is a groove formed between the first outer wall portion 302 and the middle wall portion 304 . The first slit portion 305 is arranged on the left side C1 of the stopper 300 .
如图11及图12所示，第二狭缝部306设置在止动件300的下侧B2，是形成在第二外壁部303和中壁部304之间的槽。第二狭缝部306配置在止动件300的右侧C2。As shown in FIGS. 11 and 12 , the second slit portion 306 is provided on the lower side B2 of the stopper 300 and is a groove formed between the second outer wall portion 303 and the middle wall portion 304 . The second slit portion 306 is arranged on the right side C2 of the stopper 300 .
如图12所示，止动件300从上下方向B的上侧B1安装在第一操作部81的第一操作部主体811。具体而言，止动件300将中壁部304向第一操作部主体811的第一滑动沟815插入。此时，第一操作部主体811的第一滑动沟815以外的部分，进入第一狭缝部305及第二狭缝部306。于是，第一外壁部302的侧面302a与第一操作部主体811的第一左表面814a抵接。此外，第二外壁部303的侧面303a与第一操作部主体811的第一右表面814b抵接。即，止动件300通过第一外壁部302和第二外壁部303夹持第一操作部主体811的一部分而被安装。根据以上结构，止动件300被安装在第一操作部8的第一操作部主体811。As shown in FIG. 12 , the stopper 300 is attached to the first operation part main body 811 of the first operation part 81 from the upper side B1 in the vertical direction B. As shown in FIG. Specifically, the stopper 300 inserts the middle wall portion 304 into the first slide groove 815 of the first operation portion main body 811 . At this time, the part of the first operation part main body 811 other than the first sliding groove 815 enters the first slit part 305 and the second slit part 306 . Then, the side surface 302a of the first outer wall portion 302 comes into contact with the first left surface 814a of the first operation portion main body 811 . In addition, the side surface 303 a of the second outer wall portion 303 is in contact with the first right surface 814 b of the first operation portion main body 811 . That is, the stopper 300 is attached by sandwiching a part of the first operation part main body 811 between the first outer wall part 302 and the second outer wall part 303 . According to the above structure, the stopper 300 is attached to the first operation part main body 811 of the first operation part 8 .
此外，止动件300可在第一操作部主体811的任意位置装拆。手术实施者将止动件300抵接在第一滑动件812的前端侧A1，并使止动件300卡止。于是，止动件能够限制第一滑动件812朝前端侧A1的滑动。此时，第一滑动件812朝基端侧A2的滑动不被限制。因此，止动件300允许第一滑动件812朝基端侧A2滑动。In addition, the stopper 300 can be attached and detached at any position of the first operation part main body 811 . The operator abuts the stopper 300 on the front end side A1 of the first slider 812 to lock the stopper 300 . Thus, the stopper can restrict the sliding of the first slider 812 toward the front end side A1. At this time, the sliding of the first slider 812 toward the base end side A2 is not restricted. Therefore, the stopper 300 allows the first slider 812 to slide toward the base end side A2.
手术实施者在将止动件300安装到第一操作部主体811之后，还能够从第一操作部主体811拆卸。因此，止动件300能够解除第一滑动件812朝前端侧A1的滑动限制。The operator can also detach the stopper 300 from the first operation part main body 811 after attaching it to the first operation part main body 811 . Therefore, the stopper 300 can release the restriction of the sliding of the first slider 812 toward the front end side A1.
在此，止动件300不限于本实施方式，例如也可以安装在夹持装置100的第二操作部主体821。另外，滑动件300还可以在第一操作部主体811和第二操作部主体821双方。另外，止动件300的材料没有特别限定。例如，可以使用能够弹性变形的橡胶或树脂等弹性构件，也可以使用金属制作。另外，止动件300的基部301可以形成为手术实施者容易用手抓取且容易安装到第一操作部主体811的形状。Here, the stopper 300 is not limited to this embodiment, and may be attached to the second operation part main body 821 of the clamping device 100 , for example. In addition, the slider 300 may be provided on both the first operation part main body 811 and the second operation part main body 821 . In addition, the material of the stopper 300 is not particularly limited. For example, an elastic member such as elastically deformable rubber or resin may be used, or it may be made of metal. In addition, the base portion 301 of the stopper 300 may be formed in a shape that is easy for the operator to grasp by hand and is easy to attach to the first operation portion main body 811 .

(准备)(Prepare)
作为准备作业，手术实施者(未图示)通过公知的方法确定体内组织的伤口。具体而言，手术实施者将未图示的内窥镜的插入部经由管腔的自然开口(例如，患者的口)插入食道、胃、十二指肠、大肠等消化道内，一边观察通过内窥镜的拍摄部获得的图像，一边确定作为处置对象的管腔内的组织D中形成穴状的缺陷T。As a preparatory work, a surgeon (not shown) identifies a wound in a tissue in the body by a known method. Specifically, the operator inserts the insertion part of an endoscope (not shown) into the digestive tract such as the esophagus, stomach, duodenum, and large intestine through the natural opening of the lumen (for example, the patient's mouth), and observes the passage through the internal organs. In the image obtained by the imaging unit of the scope, the cavity-like defect T in the tissue D in the lumen to be treated is specified.
(插入步骤)(insert step)
手术实施者将夹持装置100插入内窥镜通道，使夹持装置100从内窥镜通道的前端开口突出。手术实施者将设置在夹持装置100的前端侧A1的处置部1移动至缺陷T的附近。The operator inserts the clamping device 100 into the channel of the endoscope, so that the clamping device 100 protrudes from the front opening of the channel of the endoscope. The operator moves the treatment part 1 provided on the distal end side A1 of the clamping device 100 to the vicinity of the defect T. As shown in FIG.
(配置步骤)(configuration steps)
如图13所示，手术实施者一边观察图像，一边将靠近作为处置对象的缺陷T的第一部位Ta的第一可动臂31开闭。更具体地，手术实施者使第一滑动件812朝长度方向A的前端侧A1滑动。于是，第一牵引构件51朝前端侧A1移动。若与第一牵引构件51连结的第一滑动销511前进，第一可动臂31以第一转动销211作为旋转中心转动。第一可动臂31朝开闭方向B的上侧B1转动，使前端侧A1的第一臂部312从固定臂2离开。结果，第一可动臂31相对于固定臂2成为打开状态，能够夹持作为处置对象的缺陷T的第一部位Ta。As shown in FIG. 13 , the operator opens and closes the first movable arm 31 close to the first site Ta of the defect T to be treated while observing the image. More specifically, the operator slides the first slider 812 toward the front end side A1 in the longitudinal direction A. Then, the first pulling member 51 moves toward the front end side A1. When the first sliding pin 511 connected to the first pulling member 51 advances, the first movable arm 31 turns around the first turning pin 211 as a center of rotation. The first movable arm 31 rotates toward the upper side B1 in the opening and closing direction B, so that the first arm portion 312 at the front end side A1 is separated from the fixed arm 2 . As a result, the first movable arm 31 is in an open state with respect to the fixed arm 2 , and the first site Ta of the defect T to be treated can be clamped.
在该状态下，手术实施者将处于打开状态的第一可动臂31及固定臂2朝欲夹持的缺陷T的第一部位Ta移动，使第一部位Ta位于第一可动臂31和固定臂2之间。In this state, the operator moves the first movable arm 31 and the fixed arm 2 in the open state toward the first part Ta of the defect T to be clamped, so that the first part Ta is located between the first movable arm 31 and the fixed arm 2 . between fixed arms 2.
(夹持步骤)(clamping step)
在图14中，手术实施者在确认缺陷T的第一部位Ta位于第一可动臂31和固定臂2之间之后，通过使第一操作部81的第一滑动件812朝基端侧A2滑动，使第一牵引构件51朝基端侧A2移动。由此，若与第一牵引构件51连结的第一滑动销511后退，第一可动臂31的第一臂部312朝固定臂2向开闭方向B的下侧B2转动。结果，成为第一可动臂31相对于固定臂2闭合的状态，夹持作为处置对象的缺陷T的第一部位Ta。In FIG. 14 , after confirming that the first site Ta of the defect T is located between the first movable arm 31 and the fixed arm 2, the operator slides the first slider 812 of the first operation part 81 toward the base end side A2. , to move the first pulling member 51 toward the base end side A2. Accordingly, when the first slide pin 511 connected to the first pulling member 51 moves backward, the first arm portion 312 of the first movable arm 31 turns toward the lower side B2 in the opening and closing direction B toward the fixed arm 2 . As a result, the first movable arm 31 is in a closed state with respect to the fixed arm 2 and pinches the first site Ta of the defect T to be treated.
在手术实施者将第一滑动件812朝基端侧A2拉动的过程中，形成在第一可动臂31的基端侧A2的第一结合部311也以第一转动销211作为旋转中心朝开闭方向B转动。结果，第一结合部311进入形成在夹具保持部4的槽部41，被收容在夹具保持部4的内部。由此，缺陷T的第一部位Ta被第一可动臂31和固定臂2夹持。When the operator pulls the first slider 812 toward the base end side A2, the first coupling portion 311 formed on the base end side A2 of the first movable arm 31 is also opened toward the base end side A2 with the first rotation pin 211 as the center of rotation. Close direction B rotation. As a result, the first coupling portion 311 enters the groove portion 41 formed in the jig holding portion 4 and is accommodated inside the jig holding portion 4 . Thus, the first portion Ta of the defect T is held between the first movable arm 31 and the fixed arm 2 .
(滑动件滑动限制步骤)(Slider slide restriction step)
在图15中，在通过第一可动臂31和固定臂2夹持了缺陷T的第一部位Ta的状态下，手术实施者向第一操作部主体811安装止动件300。即，通过止动件300设定相对于第一操作部主体811的卡止位置。止动件300相比于设置在第一操作部主体811的第一滑动件812安装在前端侧A1。手术实施者将止动件300朝基端侧A2滑动，使其抵接在第一滑动件812的前端侧A1。止动件300与第一滑动件812的前端侧A1抵接，并卡止于第一操作部主体811。于是，止动件300能够限制第一滑动件812朝前端侧A1的滑动。进而，止动件300能够固定第一可动臂31和固定臂2的相对位置，维持夹持了缺陷T的第一部位Ta的状态。在此，并未限制第一滑动件812朝基端侧A2的滑动。因此，止动件300允许第一滑动件812朝基端侧A2滑动。In FIG. 15 , the operator attaches the stopper 300 to the first operation part main body 811 in a state where the first site Ta of the defect T is clamped by the first movable arm 31 and the fixed arm 2 . That is, the locking position with respect to the first operation part main body 811 is set by the stopper 300 . The stopper 300 is installed on the front end side A1 compared to the first slider 812 provided on the first operation part main body 811 . The operator slides the stopper 300 toward the base end side A2 to abut against the front end side A1 of the first slider 812 . The stopper 300 abuts against the front end side A1 of the first slider 812 and is locked to the first operating part main body 811 . Thus, the stopper 300 can restrict the sliding of the first slider 812 toward the front end side A1. Furthermore, the stopper 300 can fix the relative position of the first movable arm 31 and the fixed arm 2 and maintain the state where the first portion Ta of the defect T is clamped. Here, the sliding of the first slider 812 toward the base end side A2 is not restricted. Therefore, the stopper 300 allows the first slider 812 to slide toward the base end side A2.
(牵引步骤)(pulling step)
在图16中，手术实施者一边维持通过止动件300夹持了缺陷T的第一部位Ta的状态，另一边将处置部1整体移动至作为结扎对象的缺陷T的第二部位Tb附近。缺陷T的第二部位Tb是与缺陷T的第一部位Ta不同的部位。在这一过程中，止动件300维持第一可动臂31及固定臂2的闭合状态。In FIG. 16 , the operator moves the entire treatment part 1 to the vicinity of the second site Tb of the defect T to be ligated while maintaining the state in which the first site Ta of the defect T is clamped by the stopper 300 . The second site Tb of the defect T is a site different from the first site Ta of the defect T. During this process, the stopper 300 maintains the closed state of the first movable arm 31 and the fixed arm 2 .
(配置步骤)(configuration steps)
若手术实施者确认到处置部1到达了缺陷T的第二部位Tb附近，则开闭靠近作为处置对象的缺陷T的第二部位Tb。更具体地，手术实施者使第二滑动件822朝前端侧A1滑动。于是，第二牵引构件52朝前端侧A1移动。若与第二牵引构件52连结的第二滑动销521前进，第二可动臂32就会以第二转动销221作为旋转中心转动。第二可动臂32朝开闭方向B的下侧B2转动，使前端侧A1的第二臂部322从固定臂2分离。结果，成为第二可动臂32相对于固定臂闭合的状态，能够夹持作为处置对象的缺陷T的第二部位Tb。When the operator confirms that the treatment part 1 has reached the vicinity of the second site Tb of the defect T, the operator opens and closes the second site Tb close to the defect T which is the treatment target. More specifically, the operator slides the second slider 822 toward the front end side A1. Then, the second pulling member 52 moves toward the front end side A1. When the second sliding pin 521 connected to the second pulling member 52 advances, the second movable arm 32 turns around the second turning pin 221 as the center of rotation. The second movable arm 32 rotates toward the lower side B2 in the opening and closing direction B, and the second arm portion 322 on the front end side A1 is separated from the fixed arm 2 . As a result, the second movable arm 32 is in a closed state with respect to the fixed arm, and the second site Tb of the defect T to be treated can be clamped.
在该状态下，手术实施者将处于打开状态的第二可动臂32及固定臂2朝欲夹持的缺陷T的第二部位Tb移动，使缺陷T的第二部位Tb位于第二可动臂32和固定臂2之间。In this state, the operator moves the second movable arm 32 and the fixed arm 2 in the opened state toward the second part Tb of the defect T to be clamped, so that the second part Tb of the defect T is located in the second movable Between the arm 32 and the fixed arm 2.
(夹持步骤)(clamping step)
如图17所示，手术实施者在能够确认缺陷T的第二部位Tb位于第二可动臂32和固定臂2之间之后，通过使第二操作部82的第二滑动件822朝基端侧A2滑动，使第二牵引构件52朝基端侧A2移动。由此，若与第二牵引构件52连结的第二滑动销521后退，第二可动臂32的第二臂部322朝固定臂2向开闭方向B的上侧B1转动。结果，成为第二可动臂31相对于固定臂2闭合的状态，夹持作为处置对象的缺陷T的第二部位Tb。As shown in FIG. 17 , after the operator can confirm that the second site Tb of the defect T is located between the second movable arm 32 and the fixed arm 2, the operator moves the second slider 822 of the second operation part 82 toward the base end side. A2 slides, and the second pulling member 52 moves toward the base end side A2. Accordingly, when the second slide pin 521 connected to the second pulling member 52 retreats, the second arm portion 322 of the second movable arm 32 turns toward the upper side B1 in the opening and closing direction B of the fixed arm 2 . As a result, the second movable arm 31 is in a closed state with respect to the fixed arm 2 and pinches the second site Tb of the defect T to be treated.
在手术实施者将第二滑动件822朝基端侧A2拉动的过程中，形成在第二可动臂32的基端侧A2的第二结合部321也以第二转动销221作为旋转中心朝开闭方向B转动。结果，第二结合部321进入形成在夹具保持部4的槽部41，被收容在夹具保持部4的内部。由此，缺陷T的第二部位Tb被第二可动臂32和固定臂2夹持。When the operator pulls the second slider 822 toward the base end side A2, the second coupling portion 321 formed on the base end side A2 of the second movable arm 32 also moves toward the opening with the second rotation pin 221 as the rotation center. Close direction B rotation. As a result, the second coupling portion 321 enters the groove portion 41 formed in the jig holding portion 4 and is accommodated inside the jig holding portion 4 . Thus, the second portion Tb of the defect T is held between the second movable arm 32 and the fixed arm 2 .
(滑动件滑动限制步骤)(Slider slide restriction step)
在图18中，手术实施者能够将安装在第一操作部主体811的止动件300从第一操作部主体811拆卸下来。若止动件300被拆卸下来，止动件300能够解除第一滑动件812朝前端侧A1的滑动。因此，手术实施者能够再次使第一滑动件812朝前端侧A1滑动。若使第一滑动件812朝前端侧A1滑动，第一可动臂就会朝开闭方向B的上侧B 1转动，使第一可动臂31从固定臂2离开。于是，手术实施者使第一可动臂31过渡到相对于固定臂2打开的状态，能够解除夹持缺陷T的第一部位Ta的状态。接着，手术实施者使第一可动臂31靠近与缺陷T的第一部位Ta不同的第三部位Tc。手术实施者使第一滑动件812朝长度方向A的前端侧A1滑动。于是，成为第一可动臂31相对于固定臂2打开的状态，能够夹持缺陷T的第三部位Tc。手术实施者通过使第一操作部81的第一滑动件812朝基端侧A2滑动，使第一可动臂31相对于固定臂2闭合，夹持作为处置对象的缺陷T的第三部位Tc。需要说明的是，该步骤无需一定在第二可动臂32和固定臂2夹持了缺陷T的第二部位Tb之后实施。即，如图15及图16所示，在通过第一可动臂31和固定臂2夹持了缺陷T的第一部位Ta的状态下，手术实施者能够将安装在第一操作部主体811的止动件300从第一操作部主体811拆卸。该情况下，如上所述，手术实施者使第一可动臂31过渡到相对于固定臂2打开的状态，从而解除夹持了缺陷T的第一部位Ta的状态。接着，手术实施者通过使第一操作部81的第一滑动件812朝基端侧A2滑动，使第一可动臂31相对于固定臂2闭合，能够夹持作为处置对象的缺陷T的第三部位Tc。In FIG. 18 , the operator can detach the stopper 300 attached to the first operation part main body 811 from the first operation part main body 811 . If the stopper 300 is detached, the stopper 300 can release the sliding of the first sliding member 812 toward the front end side A1. Therefore, the operator can slide the first slider 812 toward the front end side A1 again. When the first slider 812 is slid toward the front end side A1, the first movable arm turns toward the upper side B1 in the opening and closing direction B, and the first movable arm 31 is separated from the fixed arm 2 . Then, the operator transitions the first movable arm 31 to the state opened relative to the fixed arm 2 , and can release the state of clamping the first site Ta of the defect T. Next, the operator brings the first movable arm 31 closer to the third site Tc different from the first site Ta of the defect T. As shown in FIG. The operator slides the first slider 812 toward the front end side A1 in the longitudinal direction A. As shown in FIG. Then, the first movable arm 31 is in an open state with respect to the fixed arm 2 , and the third site Tc of the defect T can be clamped. The operator slides the first slider 812 of the first operation part 81 toward the base end side A2, closes the first movable arm 31 relative to the fixed arm 2, and clamps the third site Tc of the defect T to be treated. It should be noted that this step does not necessarily have to be performed after the second movable arm 32 and the fixed arm 2 clamp the second portion Tb of the defect T. That is, as shown in FIG. 15 and FIG. 16 , in the state where the first part Ta of the defect T is clamped by the first movable arm 31 and the fixed arm 2, the operator can place the first operating part body 811 on the first operating part main body 811. The stopper 300 is detached from the first operation part main body 811. In this case, as described above, the operator transitions the first movable arm 31 to the state opened with respect to the fixed arm 2 to release the state where the first site Ta of the defect T is clamped. Next, the operator slides the first slider 812 of the first operation part 81 toward the base end side A2, closes the first movable arm 31 relative to the fixed arm 2, and can clamp the third part of the defect T to be treated. Site Tc.

在图19中，在通过第一可动臂31和固定臂2夹持了缺陷T的第三部位Tc的状态下，手术实施者再次向第一操作部主体811安装止动件300。止动件300相比于设置在第一操作部主体811的第一滑动件812安装在前端侧A1。手术实施者将止动件300朝基端侧A2滑动，使其抵接在第一滑动件812的前端侧A1。止动件300与第一滑动件812的前端侧A1抵接，并卡止于第一操作部主体811。于是，止动件300能够限制第一滑动件812朝前端侧A1的滑动。进而，止动件300能够维持通过第一可动臂31和固定臂2夹持了缺陷T的第三部位Tc的状态。在此，并未限制第一滑动件812朝基端侧A2的滑动。因此，止动件300允许第一滑动件812朝基端侧A2滑动。In FIG. 19 , the operator attaches the stopper 300 to the first operating part main body 811 again in a state where the third site Tc of the defect T is clamped by the first movable arm 31 and the fixed arm 2 . The stopper 300 is installed on the front end side A1 compared to the first slider 812 provided on the first operation part main body 811 . The operator slides the stopper 300 toward the base end side A2 to abut against the front end side A1 of the first slider 812 . The stopper 300 abuts against the front end side A1 of the first slider 812 and is locked to the first operating part main body 811 . Thus, the stopper 300 can restrict the sliding of the first slider 812 toward the front end side A1. Furthermore, the stopper 300 can maintain the state where the third site Tc of the defect T is sandwiched between the first movable arm 31 and the fixed arm 2 . Here, the sliding of the first slider 812 toward the base end side A2 is not restricted. Therefore, the stopper 300 allows the first slider 812 to slide toward the base end side A2.
然后，若操作部8的第一滑动件812进一步朝长度方向A的基端侧A2滑动，夹具保持部4使第一可动臂31的第一结合部311卡止在夹具保持部4的内部，将第一可动臂31被锁定为无法打开。即，在预先设定的锁定位置，第一可动臂31的基端部(第一结合部311)卡止于夹具保持部4而被锁定。另外，若操作部8的第二滑动件822进一步朝长度方向A的基端侧A2滑动，夹具保持部4使第二可动臂32的第二结合部321卡止在夹具保持部4的内部，将第二可动臂32被锁定为无法打开。即，在预先设定的锁定位置，第二可动臂32的基端部(第二结合部321)卡止于夹具保持部4而被锁定。Then, when the first slider 812 of the operation part 8 further slides toward the proximal end side A2 in the longitudinal direction A, the jig holding part 4 locks the first coupling part 311 of the first movable arm 31 inside the jig holding part 4 , the first movable arm 31 is locked so that it cannot be opened. That is, at the preset locked position, the base end portion (first coupling portion 311 ) of the first movable arm 31 is locked by the jig holding portion 4 . In addition, when the second slider 822 of the operation part 8 further slides toward the proximal side A2 in the longitudinal direction A, the jig holding part 4 locks the second coupling part 321 of the second movable arm 32 inside the jig holding part 4 , the second movable arm 32 is locked so that it cannot be opened. That is, at the preset locked position, the base end portion (second coupling portion 321 ) of the second movable arm 32 is locked by the clip holding portion 4 .
需要说明的是，卡止位置相比于锁定位置位于更靠前端侧A1的位置。It should be noted that the locked position is located closer to the front end side A1 than the locked position.
(连接解除、留置步骤)(Connection release, retention steps)
通过上述处置，如图19所示，作为处置对象的缺陷T的第二部位Tb和第三部位Tc成为被处置部1夹持的状态。在该状态下，手术实施者若使第一操作部81的第一滑动件812及第二操作部82的第二滑动件822进一步朝基端侧A2滑动，第一牵引构件51及第二牵引构件52朝基端侧A2移动。第一牵引构件51及第二牵引构件52分别与第一滑动销511及第二滑动销521可装拆地结合。例如，通过将第一牵引构件51朝基端侧A2牵引，第一牵引构件51的切口部512变形或者断裂，第一滑动销511从第一滑动销孔510被拔出，从而能够解除结合。即，若第一滑动件812朝基端侧A2滑动而越过锁定位置到达预先设定的留置位置，第一牵引构件51发生变形或者断裂，解除处置部1与所述供给器200之间的连接。另外，通过将第二牵引构件52朝基端侧A2牵引，第二牵引构件52的切口部522变形或者断裂，第二滑动销521从第二滑动销孔520被拔出，从而能够解除结合。即，若第二滑动件822朝基端侧A2滑动而越过锁定位置到达预先设定的留置位置，第二牵引构件52发生变形或者断裂，解除处置部1与所述供给器200之间的连接。需要说明的是，第一牵引构件51及第二牵引构件52和第一滑动销511及第二滑动销521发生结合的具体结构，不限于本实施方式。Through the above treatment, as shown in FIG. 19 , the second site Tb and the third site Tc of the defect T to be treated are sandwiched by the treatment part 1 . In this state, if the operator further slides the first slider 812 of the first operation part 81 and the second slider 822 of the second operation part 82 toward the base end side A2, the first traction member 51 and the second traction member 52 moves toward the proximal side A2. The first traction member 51 and the second traction member 52 are detachably combined with the first slide pin 511 and the second slide pin 521 respectively. For example, when the first pulling member 51 is pulled toward the base end side A2, the notch portion 512 of the first pulling member 51 is deformed or broken, and the first slide pin 511 is pulled out from the first slide pin hole 510 to release the connection. That is, if the first slider 812 slides toward the proximal end side A2 and crosses the locked position to reach the preset indwelling position, the first traction member 51 is deformed or broken, and the connection between the treatment part 1 and the feeder 200 is released. In addition, when the second pulling member 52 is pulled toward the base end side A2, the notch portion 522 of the second pulling member 52 is deformed or broken, and the second sliding pin 521 is pulled out from the second sliding pin hole 520 to release the connection. That is, if the second slider 822 slides toward the proximal end side A2 and crosses the locked position to reach the preset indwelling position, the second pulling member 52 is deformed or broken, and the connection between the treatment part 1 and the feeder 200 is released. It should be noted that the specific structure in which the first traction member 51 and the second traction member 52 are combined with the first slide pin 511 and the second slide pin 521 is not limited to this embodiment.
如图20所示，若手术实施者使第一牵引构件51及第二牵引构件52朝基端侧A2移动的力量超过规定值，如前所述，第一牵引构件51及第二牵引构件52和第一滑动销511及第二滑动销521之间的结合将被解除。此时，具备牵引构件5、操作线6、护套7、操作部8的供给器200和安装在操作部8的止动件300，解除与具备固定臂2、可动臂3、夹具保持部4的处置部1之间的连接。由此，以第一可动臂31和固定臂2夹持缺陷T的第三部位Tc且第二可动臂32和固定臂2夹持缺陷T的第二部位Tb的状态，处置部1被留置于管腔内(体内)。As shown in FIG. 20, if the operator moves the first traction member 51 and the second traction member 52 toward the base end side A2 with a force exceeding a predetermined value, as described above, the first traction member 51, the second traction member 52 and the The coupling between the first sliding pin 511 and the second sliding pin 521 will be released. At this time, the feeder 200 provided with the traction member 5, the operation wire 6, the sheath 7, the operation part 8, and the stopper 300 installed on the operation part 8 release the connection with the fixed arm 2, the movable arm 3, and the clamp holding part. 4 connections between the treatment part 1. Thus, in a state where the first movable arm 31 and the fixed arm 2 clamp the third site Tc of the defect T, and the second movable arm 32 and the fixed arm 2 clamp the second site Tb of the defect T, the treatment part 1 is closed. Indwelling in the lumen (in the body).
需要说明的是，图18所示的滑动件滑动限制解除步骤及图19所示的滑动件滑动限制解除步骤并非必须要实施。即，在图17所示的夹持步骤中，在由可动臂3及固定臂2夹持缺陷T的第一部位Ta及第二部位Tb的状态下，如图20所示，可将处置部1留置于管腔内。It should be noted that the step of releasing restriction on sliding of the slider shown in FIG. 18 and the step of releasing restriction on sliding of the slider shown in FIG. 19 are not necessarily implemented. That is, in the clamping step shown in FIG. 17, in the state where the first part Ta and the second part Tb of the defect T are clamped by the movable arm 3 and the fixed arm 2, as shown in FIG. Part 1 is left in the lumen.
然后，手术实施者操作夹持装置100的操作部8，将护套7向患者的体外拔出。通过上述步骤，手术实施者结束对处置对象的处置。Then, the operator operates the operation part 8 of the clamping device 100 to pull the sheath 7 out of the patient's body. Through the above steps, the operator of the operation ends the treatment of the treatment object.
在本实施方式中，通过上述特征，夹持装置100的处置部1能够封闭作为处置对象的组织D的缺陷T。In the present embodiment, the treatment unit 1 of the clamping device 100 can close the defect T of the tissue D to be treated by virtue of the above features.
另外，在本实施方式中，止动件300能够将第一可动臂31的第一结合部311卡止在夹具保持部4的内部，即使不锁定也能够限制第一滑动件812朝前端侧A1的滑动。进一步地，止动件300能够固定第一可动臂31和固定臂2的相对位置，维持夹持了缺陷T的第一部位Ta的状态。因此，手术实施者无需抑制第一操作部81的第一滑动件812朝前端侧A1的滑动，就能够操作第二操作部82的第二滑动件822。因此，夹持装置100的操作变得容易，能够缩短手术所需的时间。In addition, in this embodiment, the stopper 300 can lock the first coupling portion 311 of the first movable arm 31 inside the clip holding portion 4, and can restrict the first slider 812 from moving toward the front end side even if it is not locked. A1 slide. Furthermore, the stopper 300 can fix the relative position of the first movable arm 31 and the fixed arm 2 , and maintain the state of clamping the first part Ta of the defect T. Therefore, the operator can operate the second slider 822 of the second operation part 82 without suppressing the sliding of the first slider 812 of the first operation part 81 toward the front end side A1. Therefore, the operation of the clamping device 100 becomes easy, and the time required for surgery can be shortened.
另外，在本实施方式中，止动件300不限制第一滑动件812朝基端侧A2的滑动。止动件300能够允许第一滑动件812朝基端侧A2的滑动。因此，即使在通过第一可动臂31和固定臂2夹持组织的力不足的情况下，手术实施者也能够使第一滑动件812朝基端侧A2滑动，以更大的力夹持组织。于是，能够防止组织从臂滑落。In addition, in the present embodiment, the stopper 300 does not restrict the sliding of the first slider 812 toward the base end side A2. The stopper 300 can allow the sliding of the first slider 812 toward the base end side A2. Therefore, even when the tissue is clamped with insufficient force by the first movable arm 31 and the fixed arm 2, the operator can slide the first slider 812 toward the base end side A2 to clamp the tissue with a greater force. . Thus, tissue can be prevented from slipping off the arm.
另外，在本实施方式中，手术实施者能够将已安装在第一操作部主体811的止动件300从第一操作部主体811拆卸。因此，手术实施者能够反复变更止动件300的位置。另外，手术实施者能够解除第一滑动件812朝前端侧A1的滑动限制。In addition, in this embodiment, the operator can detach the stopper 300 attached to the first operation part main body 811 from the first operation part main body 811 . Therefore, the operator can repeatedly change the position of the stopper 300 . In addition, the surgeon can release the restriction on the sliding of the first slider 812 toward the front end side A1.
另外，在本实施方式中，手术实施者通过拆卸止动件300解除第一滑动件812朝前端侧A1的滑动限制，使第一滑动件812能够再次朝前端侧A1滑动。手术实施者能够使第一可动臂31过渡到相对于固定臂2打开的状态，从而解除夹持着缺陷T的第一部位Ta的状态。因此，手术实施者能够容易地变更由处置部1夹持的缺陷T的位置。另外，降低在锁定可动臂3之后无法解除锁定，使手术实施者无法变更夹持组织的位置的可能性。In addition, in this embodiment, the operator removes the stopper 300 to release the sliding restriction of the first slider 812 toward the front end side A1, so that the first slider 812 can slide toward the front end side A1 again. The operator can transition the first movable arm 31 to a state opened relative to the fixed arm 2 , thereby releasing the state of clamping the first part Ta of the defect T. Therefore, the surgeon can easily change the position of the defect T clamped by the treatment part 1 . In addition, it is possible to reduce the possibility that the movable arm 3 cannot be released after locking, and the operator cannot change the position of clamping tissue.
以上，参照附图对本发明的第一实施方式进行了详细说明，但具体特征不限于该实施方式，在不脱离本发明主旨的范围内的设计变更也包含在本发明中。另外，也可以适当组合上述实施方式及如下所示变形例中的特征要素。Above, the first embodiment of the present invention has been described in detail with reference to the drawings, but specific features are not limited to this embodiment, and design changes within the range not departing from the gist of the present invention are also included in the present invention. In addition, it is also possible to appropriately combine the characteristic elements in the above-mentioned embodiment and the modified examples shown below.
(第二实施方式)(second embodiment)
以下，参照图21至图24说明本发明的第二实施方式。在下面的说明中，对于与已说明的结构共同的结构标注相同的符号并省略重复说明。需要说明的是，与第一实施方式相比，以下的实施方式均是供给器的操作部和止动件不同。因此，在以下说明中，以与第一实施方式的区别作为中心进行说明。图21是在上下方向B上从上侧B1观察本发明第二实施方式的夹持装置100A的供给器200A的操作部8A的图。图22是示出夹持装置100A的止动件300A的立体图。图23是示出夹持装置100A的止动件300A的截面图。图24是示出夹持装置100A的操作部8A及止动件300A的立体图。Hereinafter, a second embodiment of the present invention will be described with reference to FIGS. 21 to 24 . In the following description, the same reference numerals are attached to the configurations common to those already described, and repeated explanations are omitted. In addition, compared with 1st Embodiment, all the following embodiments differ in the operation part and stopper of a feeder. Therefore, in the following description, differences from the first embodiment will be mainly described. FIG. 21 is a view of the operation unit 8A of the feeder 200A of the clamping device 100A according to the second embodiment of the present invention viewed from the upper side B1 in the vertical direction B. FIG. FIG. 22 is a perspective view showing the stopper 300A of the clamping device 100A. FIG. 23 is a sectional view showing the stopper 300A of the clamping device 100A. FIG. 24 is a perspective view showing the operation portion 8A and the stopper 300A of the clamping device 100A.
本发明第二实施方式的夹持装置100A具备处置部(夹具)1、供给器200A及止动件300A。另外，供给器200A具备牵引构件5、操作线6、护套7及操作部8A。在此，处置部1、牵引构件5、操作线6及护套7与第一实施方式相同，所以省略说明及图示。A clamping device 100A according to the second embodiment of the present invention includes a treatment unit (clamp) 1 , a feeder 200A, and a stopper 300A. In addition, the feeder 200A includes a pulling member 5 , an operation wire 6 , a sheath 7 , and an operation portion 8A. Here, since the treatment part 1 , pulling member 5 , operation wire 6 , and sheath 7 are the same as those of the first embodiment, explanations and illustrations are omitted.
操作部8A具备前端部80a、第一操作部81A及第二操作部82。前端部80a和第二操作部82与第一实施方式相同，所以省略说明及图示。如图21所示，第一操作部81A具有第一操作部主体(手柄)811A、第一滑动件812及搭指部813。第一滑动件812及搭指部813同样与第一实施方式相同，所以对于第一滑动件812及搭指部813省略说明及图示。The operation portion 8A includes a front end portion 80 a , a first operation portion 81A, and a second operation portion 82 . The front end portion 80a and the second operation portion 82 are the same as those of the first embodiment, and thus description and illustration thereof will be omitted. As shown in FIG. 21 , the first operation unit 81A has a first operation unit body (handle) 811A, a first slider 812 , and a finger rest 813 . The first sliding member 812 and the finger resting portion 813 are also the same as those of the first embodiment, so description and illustration of the first sliding member 812 and the finger resting portion 813 are omitted.
如图21所示，第一操作部主体(手柄)811A具备第一外表面814A和第一滑动沟815。第一滑动沟815与第一实施方式相同，所以省略说明及图示。As shown in FIG. 21 , the first operation unit main body (handle) 811A includes a first outer surface 814A and a first slide groove 815 . The first slide groove 815 is the same as that of the first embodiment, so description and illustration are omitted.
如图21所示，第一外表面814A除了具有第一实施方式的第一外表面814的特征之外，还具备凸螺纹部814s。As shown in FIG. 21 , the first outer surface 814A includes a male thread portion 814s in addition to the characteristics of the first outer surface 814 of the first embodiment.
凸螺纹部814s沿着长度方向A设置在第一外表面814A。The convex thread portion 814s is disposed on the first outer surface 814A along the length direction A. As shown in FIG.
如图22及图23所示，止动件300A设置在第一操作部主体811A。止动件300A是大致中空圆柱状。止动件300A相比于设置在第一操作部主体811A的第一滑动件812设置在前端侧A1。止动件300A具备贯穿孔307和内周面308。As shown in FIGS. 22 and 23 , the stopper 300A is provided on the first operation portion main body 811A. The stopper 300A is substantially hollow cylindrical. The stopper 300A is provided on the front end side A1 compared to the first slider 812 provided on the first operation portion main body 811A. The stopper 300A includes a through hole 307 and an inner peripheral surface 308 .
贯穿孔307形成在止动件300A的内部。止动件300A在贯穿孔307使第一操作部主体811A贯穿，从而被安装在第一操作部主体811A。A through hole 307 is formed inside the stopper 300A. The stopper 300A penetrates the first operation part main body 811A through the through hole 307 and is attached to the first operation part main body 811A.
如图22及图23所示，内周面308形成于止动件300A的内部。内周面308是与贯穿在贯穿孔307的第一操作部主体811A相对的面。内周面308具备凹螺纹部308s。凹螺纹部308s形成为，在沿着长度方向A的止动件300A的中心轴R上，如果止动件300A以中心轴R为中心旋转，则止动件300A能够在长度方向A上移动。凹螺纹部308s与设置在第一操作部主体811A的第一外表面814A的凸螺纹部814s嵌合。As shown in FIGS. 22 and 23 , the inner peripheral surface 308 is formed inside the stopper 300A. The inner peripheral surface 308 is a surface facing the first operation part main body 811A inserted through the through hole 307 . The inner peripheral surface 308 has a female screw portion 308s. The female thread portion 308s is formed so that the stopper 300A can move in the longitudinal direction A when the stopper 300A rotates about the central axis R on the central axis R of the stopper 300A along the longitudinal direction A. The female thread portion 308s is fitted with the male thread portion 814s provided on the first outer surface 814A of the first operation portion main body 811A.
例如，若止动件300A朝中心轴R的第一方向R1旋转，则凹螺纹部308s与凸螺纹部814s螺合而使止动件300A朝长度方向A的基端侧A2移动。另外，若止动件300A朝中心轴R的第二方向R2旋转，则凹螺纹部308s与凸螺纹部814s螺合而使止动件300A朝长度方向A的前端侧A1移动。For example, when the stopper 300A rotates in the first direction R1 of the central axis R, the female thread portion 308s and the male thread portion 814s are screwed together to move the stopper 300A toward the proximal side A2 in the longitudinal direction A. Also, when the stopper 300A rotates in the second direction R2 of the central axis R, the female thread portion 308s and the male thread portion 814s are screwed together to move the stopper 300A toward the front end side A1 in the longitudinal direction A.
接着，参照图24说明第二实施方式的夹持装置100A的止动件300A的动作及作用。在本实施方式中，结扎体内组织的伤口的处置与第一实施方式相同，所以省略说明。Next, the operation and function of the stopper 300A of the clamping device 100A of the second embodiment will be described with reference to FIG. 24 . In the present embodiment, the treatment of the ligated wound of the internal tissue is the same as that in the first embodiment, so the description is omitted.
如图24所示，相比于第一滑动件812，止动件300A在第一操作部主体811A上设置在前端侧A1。另外，止动件300A的凹螺纹部308s与贯穿于贯穿孔307的第一操作部主体811A的凸螺纹部814s嵌合。因此，若手术实施者在中心轴R上使止动件300A朝第一方向R1旋转，止动件300A就会朝长度方向A的基端侧A2移动。手术实施者将止动件300A朝基端侧A2移动，使其与第一滑动件812的前端侧A1抵接。止动件300A与第一滑动件812的前端侧A1抵接，并卡止在第一操作部主体811A。于是，止动件300A能够限制第一滑动件812朝前端侧A1的滑动。进而，止动件300A能够维持固定了第一可动臂31和固定臂2的相对位置的状态。在此，第一滑动件812朝基端侧A2的滑动不被限制。因此，止动件300A能够允许第一滑动件812朝基端侧A2的滑动。As shown in FIG. 24 , the stopper 300A is provided on the front end side A1 on the first operation portion main body 811A compared to the first slider 812 . In addition, the female thread portion 308s of the stopper 300A is fitted into the male thread portion 814s of the first operation portion main body 811A penetrating through the through hole 307 . Therefore, when the operator rotates the stopper 300A in the first direction R1 on the central axis R, the stopper 300A moves toward the proximal side A2 in the longitudinal direction A. The operator moves the stopper 300A toward the proximal side A2 so as to abut against the distal side A1 of the first slider 812 . The stopper 300A abuts against the front end side A1 of the first slider 812 and is locked to the first operation part main body 811A. Then, the stopper 300A can restrict the sliding of the first slider 812 toward the front end side A1. Furthermore, the stopper 300A can maintain the state where the relative positions of the first movable arm 31 and the fixed arm 2 are fixed. Here, the sliding of the first slider 812 toward the base end side A2 is not restricted. Therefore, the stopper 300A can allow the sliding of the first slider 812 toward the base end side A2.
另外，若手术实施者使止动件300A在中心轴R上朝第二方向R2旋转，止动件300A就会朝长度方向A的前端侧A1移动。于是，止动件300A能够解除第一滑动件812朝前端侧A1底滑动限制。手术实施者能够使第一滑动件812再次朝前端侧A1滑动。若使第一滑动件812朝前端侧A1滑动，第一可动臂31就会朝开闭方向B的上侧B1转动，从而自固定臂离开。于是，手术实施者能够使第一可动臂31过渡到相对于固定臂2打开的状态。需要说明的是，作为旋转方向的第一方向R1及第二方向R2没有特别限定，第一方向R1及第二方向R2的旋转方向可以与本实施方式相反。In addition, when the operator rotates the stopper 300A in the second direction R2 on the central axis R, the stopper 300A moves toward the front end side A1 in the longitudinal direction A. Then, the stopper 300A can release the restriction of the bottom sliding of the first slider 812 toward the front end side A1. The operator can slide the first slider 812 toward the front end side A1 again. When the first slider 812 is slid toward the front end side A1, the first movable arm 31 rotates toward the upper side B1 in the opening and closing direction B, thereby separating from the fixed arm. The operator can then transition the first movable arm 31 into an open state relative to the fixed arm 2 . It should be noted that the rotation directions of the first direction R1 and the second direction R2 are not particularly limited, and the rotation directions of the first direction R1 and the second direction R2 may be opposite to those of the present embodiment.
在本实施方式中，止动件300A设置在第一操作部主体811A。因此，手术实施者在手术中无需花费时间将止动件300A安装到第一操作部主体811A或从第一操作部主体811A将其拆卸，就能够限制第一滑动件812朝前端侧A1的滑动及解除该限制。另外，减少手术实施者掉落或遗失止动件300A的可能性。In this embodiment, the stopper 300A is provided on the first operation part main body 811A. Therefore, the operator can restrict the sliding of the first slider 812 toward the front end side A1 without spending time during the operation to attach or detach the stopper 300A to or from the first operation portion main body 811A. and lift the restriction. Additionally, the possibility of the operator dropping or losing the stopper 300A is reduced.
另外，在本实施方式中，手术实施者无需在手术中将止动件300A安装到第一操作部主体811A或从第一操作部主体811A将其拆卸。因此，手术实施者能够容易限制第一滑动件812朝前端侧A1的滑动及解除该限制。In addition, in the present embodiment, the operator does not need to attach or detach the stopper 300A to or from the first operation part main body 811A during the operation. Therefore, the operator can easily restrict the sliding of the first slider 812 toward the distal end side A1 and release the restriction.
以上，参照附图对本发明的第二实施方式进行了详细说明，但具体特征不限于该实施方式，在不脱离本发明主旨的范围内的设计变更也包含在本发明。另外，也可以适当组合上述实施方式及如下所示变形例中的特征要素。As mentioned above, the second embodiment of the present invention has been described in detail with reference to the drawings, but specific features are not limited to this embodiment, and design changes within the range not departing from the gist of the present invention are also included in the present invention. In addition, it is also possible to appropriately combine the characteristic elements in the above-mentioned embodiment and the modified examples shown below.
(变形例)(Modification)
上述第一实施方式的夹持装置100可以设置多个止动件300。例如，如图25所示，止动件300可以设置在第一操作部81的第一操作部主体811和第二操作部82的第二操作部主体821。另外，止动件300也可以只设置在第二操作部主体821。另外，上述第二实施方式的夹持装置100A也可以设置多个止动件300A。另外，止动件300A可以设置在第二操作部82，也可以设置在第一操作部81A和第二操作部82双方。The clamping device 100 of the above-mentioned first embodiment may be provided with a plurality of stoppers 300 . For example, as shown in FIG. 25 , the stopper 300 may be provided on the first operation part main body 811 of the first operation part 81 and the second operation part main body 821 of the second operation part 82 . In addition, the stopper 300 may be provided only on the second operation part main body 821 . In addition, the holding device 100A of the second embodiment described above may be provided with a plurality of stoppers 300A. In addition, the stopper 300A may be provided on the second operation part 82 or may be provided on both the first operation part 81A and the second operation part 82 .
另外，第一实施方式的止动件300也可以相对于第一操作部主体811的第一滑动沟815无法滑动。例如，夹持装置100，在第一操作部主体811沿着长度方向A具备多个与止动件300的长度方向A的长度匹配的第一滑动沟815。止动件300可根据第一滑动槽815的位置变更设置于第一操作部主体811的位置。因此，手术实施者无需滑动止动件300，将止动件300安装在靠近设置于第一操作部主体811的第一滑动件812的前端侧A1的第一滑动沟815，就能够限制第一滑动件812朝前端侧A1的滑动。In addition, the stopper 300 of the first embodiment may not be slidable with respect to the first slide groove 815 of the first operation part main body 811 . For example, the clamping device 100 has a plurality of first sliding grooves 815 along the longitudinal direction A on the first operating part main body 811 matching the length of the stopper 300 in the longitudinal direction A. As shown in FIG. The position of the stopper 300 disposed on the first operating part main body 811 can be changed according to the position of the first sliding groove 815 . Therefore, the operator does not need to slide the stopper 300, and installs the stopper 300 on the first sliding groove 815 close to the front end side A1 of the first slider 812 provided on the first operation part main body 811, and can restrict the first slide. The slider 812 slides toward the front end side A1.
另外，第一实施方式的止动件300通过安装到第一操作部主体811或从第一操作部主体811拆卸来限制第一滑动件812朝前端侧A1的滑动，但止动件300也可以具备带有凹凸的旋转部，由此在第一操作部主体811滑动而移动到安装位置。这种情况下，止动件300例如可在第一滑动面815a结合止动件300的旋转部，通过设置允许朝第一操作部主体811的前端侧A1滑动且限制朝基端侧A2滑动的多个凹凸，构成公知的棘轮结构。In addition, the stopper 300 of the first embodiment restricts the sliding of the first slider 812 toward the front end side A1 by being attached to or detached from the first operation part main body 811 , but the stopper 300 may be Equipped with a rotary part with unevenness, it slides on the first operation part main body 811 and moves to the mounting position. In this case, for example, the stopper 300 can be combined with the rotation part of the stopper 300 on the first sliding surface 815a, and by providing a number that allows sliding toward the front end side A1 of the first operation part main body 811 and restricts sliding toward the base end side A2. A concavo-convex structure constitutes a known ratchet structure.
另外，本发明的止动件在长度方向A的长度没有特别限定。因此，通过加长止动件的长度方向A的长度，能够调节操作部的滑动件的滑动范围。In addition, the length of the stopper of the present invention in the longitudinal direction A is not particularly limited. Therefore, by increasing the length of the stopper in the longitudinal direction A, the sliding range of the slider of the operation portion can be adjusted.
另外，上述实施方式的第一操作部81及第二操作部82可以不形成大致圆棒状。第一操作部81及第二操作部82例如可以形成多边形的棒状。第一操作部81及第二操作部82的形状没有特别限定。In addition, the first operation part 81 and the second operation part 82 of the above-mentioned embodiment need not be formed in the substantially round bar shape. The first operation part 81 and the second operation part 82 may be formed in a polygonal rod shape, for example. The shapes of the first operation part 81 and the second operation part 82 are not particularly limited.
另外，第一实施方式的止动件300在操作部8的第一操作部81及第二操作部82没有分岔的情况下也能够使用。例如，如图26所示，操作部8B以从前端部80a朝基端侧A2未以两股延伸到状态下设置有第一操作部81B及第二操作部82B。需要说明的是，第一操作部81B及第二操作部82B与第一实施方式同样地分别具有操作部主体、滑动件及搭指部。第一操作部81B及第二操作部82B在长度方向A彼此在邻接面抵接。这种情况下，止动件300也可以安装在第一操作部81B或第二操作部82B，能够限制第一滑动件812或第二滑动件822朝前端侧A1的滑动及解除该限制。In addition, the stopper 300 of the first embodiment can also be used when the first operation part 81 and the second operation part 82 of the operation part 8 are not branched. For example, as shown in FIG. 26 , the operation portion 8B is provided with a first operation portion 81B and a second operation portion 82B in a state where it does not extend in two from the front end portion 80 a toward the base end side A2 . In addition, the 1st operation part 81B and the 2nd operation part 82B respectively have an operation part main body, a slider, and a finger rest similarly to 1st Embodiment. The first operation portion 81B and the second operation portion 82B are in contact with each other in the longitudinal direction A on adjacent surfaces. In this case, the stopper 300 may be attached to the first operation part 81B or the second operation part 82B, and can restrict the sliding of the first slider 812 or the second slider 822 toward the front end side A1 and release the restriction.
另外，本发明的夹持装置可以具备图27及图28所示的止动件300C。止动件300C例如设置在第一操作部主体811的第一滑动沟815C，利用固定销300p连结基端部300Cb。止动件300C沿着长度方向A以固定销300p作为中心可转动地设置。根据该结构，如图27所示，止动件300C在前端部300Ca朝向前端侧A1时不限制第一滑动件812朝前端侧A1滑动。如图28所示，止动件300C在基端部300Cb朝向基端侧A2时，能够限制第一滑动件812朝前端侧A1的滑动。需要说明的是，止动件300C在长度方向A的长度，可与第一滑动沟815C的沟长或限制第一滑动件812的范围匹配地任意调整。另外，止动件300C可以设置在第二操作部82。In addition, the clamping device of the present invention may include a stopper 300C shown in FIGS. 27 and 28 . The stopper 300C is provided, for example, in the first sliding groove 815C of the first operation part main body 811, and is connected to the base end part 300Cb by the fixing pin 300p. The stopper 300C is rotatably provided along the longitudinal direction A with the fixing pin 300p as a center. According to this configuration, as shown in FIG. 27 , the stopper 300C does not restrict the sliding of the first slider 812 toward the front end side A1 when the front end portion 300Ca is directed toward the front end side A1 . As shown in FIG. 28 , the stopper 300C can restrict the sliding of the first slider 812 toward the distal side A1 when the proximal end portion 300Cb is directed toward the proximal side A2 . It should be noted that the length of the stopper 300C in the longitudinal direction A can be adjusted arbitrarily to match the groove length of the first sliding groove 815C or limit the range of the first sliding member 812 . In addition, a stopper 300C may be provided at the second operation portion 82 .
在上述任一实施方式中，根据本发明的组织的闭合方法，即使是大形状或不规则形状的组织也能够夹持，根据夹持装置及夹持装置的操作方法，能够使维持夹持着组织的状态的同时操作可各自动作的臂变得容易，或能够变更组织的夹持位置。In any of the above-mentioned embodiments, according to the tissue closing method of the present invention, even large-shaped or irregular-shaped tissues can be clamped, and according to the clamping device and the operation method of the clamping device, the clamping can be maintained. Simultaneous manipulation of the state of the tissue is facilitated by independently operating the arms, and the clamping position of the tissue can be changed.
