本发明属于医疗器械领域，具体涉及一种可单手操作的腔镜手术用取物器。The invention belongs to the field of medical instruments, and in particular relates to an object fetcher for endoscopic surgery that can be operated with one hand.
背景技术Background technique
随着内窥镜微创手术的发展，取物器作为用于取出腔镜手术中切除物的一种常用医疗手术器械，其应用也越来越广泛。现有的腔镜取物器大都是利用将取物袋装配于记忆合金环上，再配合外套管来控制袋口的开张与闭合，如授权公告号为CN104287782A、CN203263438U的专利均为采用上述方案。采用该方案的取物器往往由于取物袋上的记忆合金环本身的刚度有限，受力时会使取物袋袋口变形，容易跑偏，导致手术过程中收取切除物不易掌控，在给操作者带来不便的同时，也增大了不良组织或恶性肿瘤种植扩散的风险，而且上述方案的取物袋的袋口通常只能开闭一次，袋口不能辅助夹取组织，难以满足多样化的临床需求。With the development of endoscopic minimally invasive surgery, the object extractor, as a commonly used medical surgical instrument for taking out resected objects in endoscopic surgery, is more and more widely used. Most of the existing endoscopic object retrieval devices use the object retrieval bag to be assembled on the memory alloy ring, and then cooperate with the outer tube to control the opening and closing of the bag mouth. For example, the patents with the authorized announcement numbers CN104287782A and CN203263438U all adopt the above scheme . The retrieval device adopting this scheme is often due to the limited rigidity of the memory alloy ring on the retrieval bag itself. When the force is applied, the mouth of the retrieval bag will be deformed, and it is easy to deviate, which makes it difficult to control the resection during the operation. While the operator is inconvenient, it also increases the risk of bad tissue or malignant tumor implantation and spread, and the bag mouth of the above-mentioned solution can only be opened and closed once, and the bag mouth cannot assist in grasping tissues, so it is difficult to meet various needs. specific clinical needs.
为此，另外的如授权公告号为CN205163120U、CN104546028A、CN205514712U的专利提出了其他的方案解决相应问题，但是此类方案结构较为复杂且操作不易，使用时比较麻烦，大都是采用双手操作，手术医生必须一手握住取物袋的外套管，另一手推动推杆来释放取物袋，这无疑给术者带来了不便，同时也增加了延长了手术时间与增加了患者所受痛苦。For this reason, other patents such as CN205163120U, CN104546028A, and CN205514712U have proposed other schemes to solve corresponding problems, but such schemes have complex structure and difficult operation, and are cumbersome to use. Most of them are operated by both hands. It is necessary to hold the outer tube of the retrieval bag with one hand, and the other hand pushes the push rod to release the retrieval bag, which undoubtedly brings inconvenience to the operator, and also increases the prolongation of the operation time and increases the suffering of the patient.

具体实施方式Detailed ways
实施例Example
如图1所示的腔镜手术用取物器为本发明的优选方案，由取物器本体、收集袋9、安全绳10和配套的外套管1组成，其中取物器本体为腔镜夹钳的形式，包括钳杆杆身2、锁紧帽3、拨轮4、两组手柄、钳头座7、两组钳头8等部件。The extractor for endoscopic surgery as shown in Figure 1 is a preferred solution of the present invention, consisting of the extractor body, collection bag 9, safety rope 10 and matching overtube 1, wherein the extractor body is a laparoscopic clip The form of pliers includes parts such as pliers rod shaft 2, locking cap 3, dial 4, two groups of handles, pliers head seat 7, two groups of pliers heads 8.
其中，两组钳头8呈咬合的结构形式共同铰接在钳头座7上，通过钳杆杆身内部的连杆结构与后部的手柄连接，实现钳头8之间的咬合和张开动作，钳杆杆身2前端设有能相互咬合的两组钳头，锁紧帽3用以连接钳杆杆身2和手柄，旋松锁紧帽可分离钳杆杆身和手柄，手柄分为手柄后动柄5和手柄前定柄6，操作时可单手操作，具体关于手柄运动的方式以及通过连杆结构连接钳头的技术方案可参考现有的腔镜夹钳技术，如公布号为CN203483477U、CN203059840U的实用新型专利中所描述的技术方案，本实施例在此不做赘述。Among them, the two groups of pliers 8 are hinged together on the pliers seat 7 in the form of an occlusal structure, and the connecting rod structure inside the pliers shaft is connected to the handle at the rear to realize the occlusal and opening actions between the pliers 8 , the front end of the pliers shaft 2 is provided with two groups of pliers heads that can engage with each other, the locking cap 3 is used to connect the pliers shaft 2 and the handle, and the locking cap can separate the pliers shaft and the handle, and the handle is divided into The rear handle 5 of the handle and the front fixed handle 6 of the handle can be operated with one hand. For details about the way the handle moves and the technical solution for connecting the pliers head through the connecting rod structure, please refer to the existing laparoscopic clamp technology, such as publication number It is the technical solution described in the utility model patents of CN203483477U and CN203059840U, and this embodiment will not repeat them here.
本实施例将收集袋9的袋口分别穿设与两组钳头8上，这样取物器的收集袋袋口的运动通过钳头8的咬合和张开控制，可以重复打开和关闭。同时将安全绳10穿设于收集袋袋口内，并与钳头固定连接，避免收集袋在脱离钳头后失去控制。拨轮4固定在钳杆杆身2上，用来控制钳杆的旋转角度，从而实现转换收集袋9的袋口方向。外套管1套设在钳杆杆身2上，可在穿刺器的阻挡下沿取物器的钳杆杆身滑动从而使收集袋外露释放。In this embodiment, the mouth of the collection bag 9 is respectively worn on two groups of pincers 8, so that the movement of the mouth of the collection bag of the object extractor is controlled by the bite and opening of the pincers 8, and can be opened and closed repeatedly. At the same time, the safety rope 10 is passed through the mouth of the collection bag, and is fixedly connected with the pliers, so as to prevent the collection bag from losing control after breaking away from the pliers. The dial 4 is fixed on the pincer rod shaft 2 and is used to control the rotation angle of the pincer rod, so as to realize the conversion of the pocket opening direction of the collection bag 9 . The outer sleeve 1 is sleeved on the pincer shaft 2, and can slide along the pincer shaft of the extractor under the blocking of the trocar so that the collection bag is exposed and released.
关于外套管1的作用结合参见图2至图8。Regarding the function of the outer sleeve 1 , please refer to FIGS. 2 to 8 .
如图2和图3所示，在收集器处于未使用状态下时，收集袋9绕卷在咬合的钳头8上，以缩小收集袋9的体积，绕圈后的收集袋9及钳头8的整体尺寸不超过外套管1的内径，然后将其塞入外套管1内。装配时，先把取物器的钳头部分从外套管的直径较小的后端部穿入外套管体内，此时外套管1的前端部为喇叭口，外套管1的长度大于或等于钳头8的长度，保证装配后的外套管1能够完全套住钳头部分，确保收集袋袋体和安全绳不露出。钳杆杆身2上的钳头座7到拨轮4之间的距离为取物器的有效工作长度，有效工作长度应大于穿刺器的套管长度与外套管长度总和10mm～50mm，确保手术过程取物器的钳头张开到预定角度以及顺利释放收集袋。As shown in Figures 2 and 3, when the collector was in an unused state, the collection bag 9 was wound up on the engaged pincers 8 to reduce the volume of the collection bag 9, and the collection bag 9 and the pincers after the circle The overall size of 8 does not exceed the inner diameter of outer sleeve 1, and then it is inserted in the outer sleeve 1. When assembling, the pliers head part of the extractor is first inserted into the body of the outer sleeve from the rear end of the outer sleeve with a smaller diameter. At this time, the front end of the outer sleeve 1 is a bell mouth, and the length of the outer sleeve 1 is greater than or equal to that of the pliers. The length of the head 8 ensures that the assembled outer sleeve 1 can completely cover the pliers part, ensuring that the collection bag body and the safety rope are not exposed. The distance between the pincer head seat 7 on the forceps rod body 2 and the dial 4 is the effective working length of the fetcher, and the effective working length should be 10mm-50mm greater than the sum of the cannula length and the outer cannula length of the puncturer to ensure the operation The jaws of the process extractor open to a predetermined angle and release the collection bag smoothly.
如图4和图5所示，外套管的内径大于钳杆的外径，手术时将收集袋通过穿刺器，外管套1的内径不超过穿刺器的套管内径，外套管1在套管的阻挡下沿钳杆杆身2后移，从而使钳头8上的绕卷的收集袋9穿过穿刺器进入体内，此过程中应控制钳头8处于合紧状态，在通过穿刺器进入体内后，操作手柄后动柄，将钳头张开，把收集袋9的袋口打开，然后通过拨动拨轮，可以根据需要调整收集袋9的袋口方向。As shown in Figures 4 and 5, the inner diameter of the outer sleeve is greater than the outer diameter of the forceps rod. During the operation, the collection bag is passed through the trocar, and the inner diameter of the outer sleeve 1 does not exceed the inner diameter of the trocar. Move back along the pliers rod shaft 2 under the blocking, so that the coiled collection bag 9 on the pliers head 8 passes through the puncture device and enters the body. During this process, the pliers head 8 should be controlled to be in a tight state. After the inside of the body, move the handle behind the operating handle, open the pliers, open the mouth of the collection bag 9, and then adjust the direction of the mouth of the collection bag 9 as required by turning the dial.
如图6所示，外套管1的长度大于或等于钳头长度，装配时完全覆盖钳头部分。外套管的前端部1-2设有直径大于对应穿刺器的开口直径的喇叭口状结构，在手术时可在穿刺器的阻挡下沿取物器钳杆滑动，从而释放收集袋。后端部1-1采用与外套管内径相同的管口即可，外套管1的内径与绕卷在钳头上的收集袋的尺寸配合，防止在装配过程中两者过松或过紧，同时还应当保证外套管1的内径限制绕卷在钳头上的收集袋尺寸不超过穿刺器的套管内径，避免绕卷收集袋的钳头不能够通过穿刺器进入体内。As shown in FIG. 6 , the length of the outer sleeve 1 is greater than or equal to the length of the pliers, and completely covers the pliers when assembled. The front end 1-2 of the outer cannula is provided with a trumpet-shaped structure with a diameter larger than the opening diameter of the corresponding puncture device, which can slide along the forceps bar of the extractor under the blocking of the puncture device during operation, thereby releasing the collection bag. The rear end 1-1 can adopt the same nozzle as the inner diameter of the outer casing, and the inner diameter of the outer casing 1 matches the size of the collection bag wound on the pliers head to prevent the two from being too loose or too tight during the assembly process. Simultaneously also should guarantee that the inner diameter of overtube 1 limits the size of the collection bag wound on the pliers and does not exceed the sleeve pipe inner diameter of the trocar, so as to prevent the pliers of the coiled collection bag from entering the body through the trocar.
在收集组织的过程中，还可通过夹钳对组织进行夹取，如图7所示，两组钳头8在相对的啮合段上分别设有对应的啮合齿8-2，两组钳头8在闭合后呈错开状态且留有一定的缝隙，如图3中所示，不会将收集袋完全夹住，方便收集袋9相对钳头8的滑移。In the process of collecting tissue, the tissue can also be clamped by clamps, as shown in Figure 7, two sets of forceps 8 are respectively provided with corresponding engagement teeth 8-2 on the opposite engagement sections, two sets of forceps 8 are in a staggered state after closing and leave a certain gap, as shown in Figure 3, the collection bag will not be completely clamped, which facilitates the sliding of the collection bag 9 relative to the pliers head 8.
结合参见图8a，钳头8在啮合段分别设有连续的啮合齿或非连续的多段啮合齿8-2，用以在手术过程中辅助夹取组织进入收集袋，并且可以防止收集袋袋口因袋口与钳头之间摩擦力不足导致的意外滑脱，同样的，在钳头8的背部非啮合段8-3也可以设置连续的防滑齿或非连续的多段防滑齿以进一步增加钳头和收集袋的袋口之间的摩擦力，如图8b所示。在钳头8的前端设有穿线孔8-1，安全绳10的两端部分别穿过穿线孔8-1并在钳头后端的位置将安全绳10的两端打结连接。钳头8的张合由钳杆杆身内部的拉杆11拉动钳头座内的连杆结构实现其运动，钳头的张开角度在0°～90°之间。Referring to Fig. 8a, the pliers head 8 is respectively provided with continuous meshing teeth or discontinuous multi-segment meshing teeth 8-2 in the meshing section to assist in grasping the tissue into the collection bag during the operation, and to prevent the opening of the collection bag from collapsing. Due to the accidental slippage caused by insufficient friction between the mouth of the bag and the pliers, similarly, continuous anti-skid teeth or non-continuous multi-segment anti-skid teeth can be set on the back non-engaging section 8-3 of the pliers 8 to further increase the friction of the pliers. and the friction between the mouth of the collection bag, as shown in Figure 8b. A threading hole 8-1 is provided at the front end of the pliers head 8, and the two ends of the safety rope 10 pass through the threading holes 8-1 respectively and are connected by knotting the two ends of the safety rope 10 at the position of the pliers head rear end. The opening and closing of the pincer head 8 is realized by the pull rod 11 inside the pincer rod shaft pulling the connecting rod structure in the pincer head seat to realize its movement, and the opening angle of the pincer head is between 0° and 90°.
如图9a和9b所示，收集袋9内部为底部封闭的空间，下方封闭用以盛纳手术切除物，袋体材料为医用聚氨酯或尼龙薄膜，采用热熔合的方式制作，具有收集袋热熔合边9-2，并且在收集袋袋口9-1的位置设置一圈贯穿的空腔，在该空腔上设置两个袋口开孔9-3，安全绳10贯穿通过收集袋袋口的空腔后，将安全绳10的两端部从该袋口开孔引出至与钳头连接，袋口可由安全绳锁紧，同时两组钳头8分别从该袋口开孔9-3从两个方向插入收集袋袋口9-1的空腔内，便于实现对袋口的张开和闭合。As shown in Figures 9a and 9b, the inside of the collection bag 9 is a space with a closed bottom, and the bottom is closed to accommodate surgical resections. The material of the bag body is medical polyurethane or nylon film, which is made by heat fusion, and has a collection bag heat fusion edge 9-2, and set a circle through the cavity at the position of the collection bag pocket 9-1, set two pocket openings 9-3 on the cavity, and the safety rope 10 runs through the pocket of the collection bag After the cavity, the two ends of the safety rope 10 are drawn out from the opening of the pocket to be connected with the pincers, and the pockets can be locked by the safety rope, while two groups of pincers 8 are drawn from the pocket openings 9-3 respectively. Two directions are inserted into the cavity of the pocket opening 9-1 of the collection bag, which facilitates the opening and closing of the pocket opening.
图9a和图9b中的收集袋9在展开状态下为U形，袋深较浅，适用于取出较小切除物。在临床手术中，还可根据手术切除组织的实际情况选择图10中的V形收集袋或图11中的倒梯形收集袋，V形收集袋上端大，下端小，方便放入切除物，在取出切除物过程中由于挤压，收集袋下端变大呈圆柱状，利于取出手术切口。倒梯形收集袋的上端小，下端大，收集袋口缩口迅速，能有效的防止袋中的切除物外溢，适合盛纳较大切除物。不同形状的收集袋，收集袋袋口9-1及安全绳10的设置方式均相同。The collecting bag 9 in Fig. 9a and Fig. 9b is U-shaped in the unfolded state, and the depth of the bag is relatively shallow, which is suitable for taking out smaller resections. In clinical operations, the V-shaped collection bag in Figure 10 or the inverted trapezoidal collection bag in Figure 11 can also be selected according to the actual situation of the surgically removed tissue. Due to extrusion during the removal of the resected object, the lower end of the collection bag becomes larger and becomes cylindrical, which is beneficial for removing the surgical incision. The upper end of the inverted trapezoidal collection bag is small, the lower end is large, and the mouth of the collection bag shrinks quickly, which can effectively prevent the resections in the bag from overflowing, and is suitable for holding larger resections. For collection bags of different shapes, the setting modes of the collection bag opening 9-1 and the safety rope 10 are all the same.
安全绳10在袋口套装入钳头的状态下，需要将安全绳10设置成收束状态，避免安全绳在袋口空腔内缠绕打结，如图12a和图12b所示，在收束状态下，将安全绳10的中间部分呈S形绕折后套装安全绳套管12，以缩短安全绳10的总体长度，以匹配收集袋袋口的长度。结合参见图7，收集袋9的袋口空腔部分套装在钳头8上从而组成刚性支撑端，为收集袋9提供足够的支撑力，袋口的其余部分则为柔软的自由端，当钳头8打开至最大角度时，自由端可受力绷紧，在装入手术切除物时该端不会下垂，以方便取物。钳头8控制袋口的张合，从而实现收集袋在手术过程中的重复打开和关闭。收束后的安全绳10两端部从袋口引出后分别穿过两组钳头8上的穿线孔8-1，并在钳头的尾部以安全绳绳结13的方式连接成环，将安全绳10整体呈一个环形穿过两组钳头的穿线孔8-1，通过安全绳10将收集袋9和钳头8之间形成可套装和分离的可靠连接方式，防止收集袋9掉入体内。When the safety rope 10 is put into the pliers at the mouth of the bag, it is necessary to set the safety rope 10 into a constricted state to avoid the safety rope from being entangled and knotted in the pocket cavity, as shown in Figure 12a and Figure 12b, when the In this state, the middle part of the safety rope 10 is folded in an S shape and then fitted with the safety rope sleeve 12 to shorten the overall length of the safety rope 10 to match the length of the opening of the collection bag. Referring to Fig. 7, the sack cavity part of the collection bag 9 is set on the pliers head 8 to form a rigid support end, which provides sufficient support for the collection bag 9, and the rest of the sack is a soft free end, when the pliers When the head 8 is opened to the maximum angle, the free end can be stressed and tightened, and the end will not droop when the surgical resection is loaded, so as to facilitate the extraction. The pincer head 8 controls the opening and closing of the bag mouth, thereby realizing the repeated opening and closing of the collection bag during the operation. The two ends of the bundled safety rope 10 are led out from the mouth of the bag and pass through the threading holes 8-1 on the two groups of pliers 8 respectively, and are connected into a loop at the tail of the pliers in the form of a safety rope knot 13. The safety rope 10 passes through the threading holes 8-1 of the two groups of pliers in a ring shape, and forms a reliable connection between the collection bag 9 and the pliers 8 through the safety rope 10, which can prevent the collection bag 9 from falling into the in vivo.
安全绳套管12为热收缩管或塑料软管，安全绳10在收束后不能过松或过紧，应有一定的阻力，在收集完组织后，安全绳10的两端受力，收束处的安全绳可从安全绳套管12中释放脱出得到原长，如图13a和图13b所示，收集袋9在收集完手术切除物后，在外力的作用下收集袋9和袋口空腔内的安全绳10逐渐滑向钳头8的前端，从而收紧袋口。当收集袋9从钳头上脱离时，安全绳10释放得到原长，安全绳绳结13在钳头的穿线孔8-1处受阻挂于钳头8上，而收集袋的袋口则由于重力的作用进一步被安全绳锁紧。安全绳10的总长度应大于穿刺器的套管长度的两倍，保证能够将钳头顺利从穿刺器中退出，并能保持部分安全绳位于体外。The safety rope sleeve 12 is a heat-shrinkable tube or a plastic hose, and the safety rope 10 cannot be too loose or too tight after being bundled, and there should be a certain resistance. The safety rope at the bundle can be released from the safety rope sleeve 12 to obtain the original length, as shown in Figure 13a and Figure 13b, after the collection bag 9 has collected the surgical resection, the collection bag 9 and the mouth of the bag are collected under the action of external force. The safety rope 10 in the cavity slides gradually to the front end of the pliers head 8, thereby tightening the mouth of the bag. When the collecting bag 9 broke away from the pincers, the safety rope 10 was released to obtain the original length, and the safety rope knot 13 was hindered at the threading hole 8-1 of the pincers and hung on the pincers 8, and the sack of the collecting bag was due to The effect of gravity is further locked by the safety rope. The total length of the safety rope 10 should be greater than twice the length of the sleeve of the puncture device, so as to ensure that the pincer head can be withdrawn from the puncture device smoothly, and a part of the safety rope can be kept outside the body.
以下结合图14至图17详细说明本实施例在手术中的使用过程。操作者单手操作取物器直穿穿刺器14，由于取物器上的外套管1的喇叭口端的直径大于套管的开口，于是外套管1沿钳杆杆身2往后移，取物器上的钳头8及绕卷的收集袋9穿入套管进入人体腹腔，并使绕卷在钳头8上的收集袋9外露释放在体内。拨动手柄后动柄5，打开收集袋9的袋口，根据需要拨动拨轮调整袋口方向。当切除组织收集完成后，操作者拨动手柄后动柄5关闭取物器袋口，同时后撤取物器本体，此时关闭袋口后的收集袋在自身重力及套管的阻挡下沿着闭合的钳头8逐渐滑移至钳头最前端，并在袋口完全收紧后从钳头上脱离。收束的安全绳10得到释放，并挂于钳头，从而锁紧收集袋的袋口，并对留置在体内的收集袋9形成牵引。将取物器和套管移除体外，此时部分安全绳10通过取物器从切口处引出，操作者握住安全绳并将其剪断，从而分离钳杆杆身与收集袋，然后连同安全绳一起将收集袋拖出体外，取出收集袋内的切除物。The use process of this embodiment in surgery will be described in detail below in conjunction with FIG. 14 to FIG. 17 . The operator operates the extractor with one hand to directly penetrate the puncturer 14. Since the diameter of the bell mouth end of the outer sleeve 1 on the extractor is larger than the opening of the sleeve, the outer sleeve 1 moves backward along the forceps rod shaft 2 to extract the object. The clamp head 8 and the coiled collection bag 9 on the device penetrate the casing into the abdominal cavity of the human body, and the coiled collection bag 9 on the clamp head 8 is exposed and released in the body. After the handle is moved, the handle 5 is opened to open the mouth of the collecting bag 9, and the direction of the mouth of the bag is adjusted by turning the dial as required. After the collection of resected tissues is completed, the operator moves the handle 5 to close the mouth of the extractor, and withdraws the body of the extractor at the same time. The closed pincer head 8 gradually slides to the front end of the pincer head, and breaks away from the pincer head after the bag mouth is fully tightened. The bundled safety rope 10 is released and hung on the pliers, thereby locking the mouth of the collection bag and forming traction to the collection bag 9 left in the body. Remove the extractor and the cannula from the body, at this time, part of the safety rope 10 is led out from the incision through the extractor, the operator holds the safety rope and cuts it, thereby separating the body of the pliers rod and the collection bag, and then together with the safety rope 10 Pull the collection bag out of the body together with the rope, and take out the excised material in the collection bag.
