The application of medical stapler has many advantages such as less blood loss during operation, shorter operation time, reduction of manual operation error, and quick recovery of postoperative function.
大部分管型吻合器在闭合过程中，医生要根据病人的个体状况选择合适的闭合间隙，闭合间隙的大小根据吻合器的视窗中的指针的位置来判断。但是在器械闭合过程中，医生要始终观察视窗中的指针，如果不留神，指针容易错过最佳位置，造成闭合间隙过小，组织被过度压缩，此时如果将指针调回到最佳位置，组织可能已经不处于最佳的状态，最终可能影响吻合效果，也使医生经常处于精神紧张的状态，很难得到一个精准的闭合位置，吻合器闭合效果较差，使得吻合器的操作难度较大。During the closing process of most tubular staplers, the doctor should select a suitable closing gap according to the individual condition of the patient, and the size of the closing gap is judged according to the position of the pointer in the window of the stapler. However, during the closing process of the instrument, the doctor should always observe the pointer in the window. If the pointer is not careful, the pointer will easily miss the best position, resulting in too small closing gap and excessive compression of the tissue. At this time, if the pointer is adjusted back to the best position, The tissue may not be in the best state, which may eventually affect the anastomotic effect, and also make the doctor often in a state of mental stress, it is difficult to obtain an accurate closing position, and the closing effect of the stapler is poor, making the operation of the stapler more difficult .
因此，在保证吻合器的闭合精度下，降低吻合器的操作难度，使吻合器的操作更加人性化，同时降低由于医生误操作导致的人体组织损伤是本领域人员需要解决的一个问题。Therefore, while ensuring the closing accuracy of the stapler, it is a problem to be solved by those skilled in the art to reduce the operation difficulty of the stapler, make the operation of the stapler more humanized, and at the same time reduce the damage of human tissue caused by the doctor's misoperation.

具体实施方式detailed description
本发明的核心是提供一种具有示声功能的吻合器，在保证吻合器闭合精度的情况下，提供给医生更加人性化的操作方式，同时降低了由于操作不当导致的损伤人体组织的风险。The core of the present invention is to provide a stapler with a sound display function, which provides doctors with a more humanized operation mode while ensuring the closing accuracy of the stapler, and at the same time reduces the risk of damage to human tissue caused by improper operation.
为了使本领域技术人员更好地理解本发明的技术方案，下面将结合附图和具体实施例对本发明作进一步的详细说明。In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
参见图1-图3，在本发明的一个实施例中，吻合器包括外壳1、设置于外壳1内部的丝杆2，以及分别与丝杆2两端连接的尾部旋钮3和抵钉座4，还包括与丝杆2连接且可与丝杆2同步运动的示声架5、与尾部旋钮3连接的示声齿轮31、与示声架5通过第一弹性件572连接的示声块53，示声块53能够与示声齿轮31接触。示声块53的近端可以为齿状、锥状、半圆状或球状，优选地为直齿状。上述示声齿轮31优选地也为连续直齿状。第一弹性件572可以为压簧或弹片等。示声架5可以通过焊接或粘接直接固定在丝杆2上，压簧的一端可以通过焊接或嵌套等连接方式与示声块53连接。在医生进行手术操作初期，如图8所示，示声块53的近端不与示声齿轮31接触，随着医生逐渐旋转尾部旋钮3来减小抵钉座4与外壳1之间的闭合间隙，丝杆2也带动示声架5向近端运动，从而示声架5带动示声块53接近示声齿轮31，当快要到达合适的闭合间隙时，示声块53的近端与示声齿轮31接触，继续旋转尾部旋钮3以带动示声架5向近端运动，此时由于第一弹性件572的弹性连接作用，可使示声齿轮31与示声块53持续接触一段时间(如图9所示)并发出咔咔咔的提示声音，这样可提醒医生快要到达合适的闭合间隙，此时医生可以放慢旋转尾部旋钮3的速度，并结合观察吻合器的视窗来判断准确位置，当指针指向合适位置时，按下扳机，外壳1内部的钉仓则会推出缝钉，缝钉与抵钉座4接触，从而缝合组织，同时环形刀对组织进行切断。该吻合器的示声设计使得整个手术过程可按声音提示进行，而不必仅依靠医生感觉和经验来判断，由此在保证吻合器的闭合精度的情况下，降低了由于操作不当而过度挤压人体组织从而导致损伤组织的风险。Referring to Figures 1-3, in one embodiment of the present invention, the stapler includes a housing 1, a screw 2 disposed inside the housing 1, and a tail knob 3 and an abutment seat 4 respectively connected to both ends of the screw 2 , also includes the sounding frame 5 connected with the screw mandrel 2 and can move synchronously with the screw mandrel 2, the sounding gear 31 connected with the tail knob 3, and the sounding block 53 connected with the sounding frame 5 through the first elastic member 572 , the sound indicating block 53 can be in contact with the sound indicating gear 31 .

The above-mentioned sounding gear 31 is also preferably in the shape of continuous straight teeth. The first elastic member 572 may be a compression spring or an elastic sheet, or the like. The sounding frame 5 can be directly fixed on the screw rod 2 by welding or bonding, and one end of the compression spring can be connected with the sounding block 53 by welding or nesting. At the initial stage of the doctor’s operation, as shown in Figure 8, the proximal end of the sounding block 53 is not in contact with the sounding gear 31, as the doctor gradually rotates the tail knob 3 to reduce the closure between the anvil 4 and the shell 1 The screw mandrel 2 also drives the sound indicating frame 5 to move towards the proximal end, so that the sound indicating frame 5 drives the sound indicating block 53 to approach the sound indicating gear 31. The sound gear 31 is in contact, and the tail knob 3 is continued to be rotated to drive the sound display frame 5 to move to the proximal end. At this time, due to the elastic connection effect of the first elastic member 572, the sound display gear 31 can be continuously contacted with the sound display block 53 for a period of time ( As shown in Figure 9) and make a prompt sound of clicking, which can remind the doctor that the appropriate closing gap is about to be reached. At this time, the doctor can slow down the speed of rotating the tail knob 3 and judge the exact position by observing the window of the stapler , when the pointer points to a proper position, press the trigger, the staple magazine inside the shell 1 will push out the staples, and the staples will contact with the nail abutment seat 4, thereby suturing the tissue, and at the same time, the circular knife cuts the tissue. The acoustic design of the stapler enables the entire operation process to be carried out according to the voice prompts, instead of relying on the doctor's feeling and experience to judge, thereby reducing excessive extrusion due to improper operation while ensuring the closing accuracy of the stapler human tissue thereby causing a risk of tissue damage.

Specifically, the shell 1 is provided with a shell protrusion 11, the sound frame is provided with a pull hook 54, and one end of the second elastic member 52 is connected to the shell protrusion 11. The other end is connected to the drag hook 54. A through groove 56 is arranged on the sounding frame 5 , and the shell protrusion 11 can be placed in the through groove 56 . The second elastic member 52 can be a tension spring or an elastic belt. When the screw mandrel 2 moves to the proximal end, the screw protrusion 21 pushes the sounding frame protrusion 51 to move the sounding frame 5 to the proximal end; when the screw mandrel 2 moves to the far end, the tension spring pulls the sounding frame 5 to remote movement. The design of adding the second elastic member 52 enables the sounding frame 5 to move longitudinally along the moving direction of the screw rod more smoothly, and is convenient for installation.
参见图5-图7，为了使示声块53更稳定的相对于示声架5运动，示声架5上设置有限位槽57，示声块53设置于限位槽57内，从而使示声块53沿丝杆2方向纵向运动以防止左右摆动。限位槽57内设置有固定杆571，示声块53设置有安装孔532，压簧套接于固定杆571上，固定杆571设置于安装孔532内且可滑动，固定杆571将示声块53与压簧、示声架连接在一起。限位槽57的内侧壁设置有第一通道573，示声块53的侧部相对第一通道573而设置有侧限位凸起531，从而防止示声块53在上下方向晃动。优选地，限位槽57的左右两个内侧壁均设置有第一通道573。限位槽57的底侧内壁上设置有第二通道，在第二通道上设置有凸出部55(参见图3)，示声块53的底部相对凸出部55而设置有凹槽533，这样在示声块53纵向运动时，凹槽533的纵向方向的两个边缘限定了凸出部55的运动范围，从而限定了示声块53的运动范围，这样防止示声块在操作过程中脱落或挤压错位。上述凸出部55可以为安装在示声架5底部上的螺钉或螺栓。5-7, in order to make the sound display block 53 move more stably relative to the sound display frame 5, the sound display frame 5 is provided with a limit groove 57, and the sound display block 53 is arranged in the limit groove 57, so that the display The sound block 53 moves longitudinally along the direction of the screw mandrel 2 to prevent it from swinging left and right.
