本发明涉及一种腔内缝合器。The invention relates to an intracavity stapler.
【背景技术】【Background technique】
随着腹腔镜技术的飞速发展，目前腹部及胸部外科大部分手术均可实现腔镜下完成，大大降低了患者的手术创伤及并发症的发生，缩短术后恢复时间。With the rapid development of laparoscopic technology, most operations in abdominal and thoracic surgery can be completed under laparoscopy, which greatly reduces the surgical trauma and complications of patients, and shortens postoperative recovery time.
目前腔镜手术存在的主要难点仍然是内镜下的重建操作，如胆道重建、肠道重建、泌尿系统重建等等，而重建手术中重点是缝合、打结，目前常规腹腔镜手术均采用带线针缝合后打结、腔内直线切割闭合器、管型吻合器完成，采用带线针缝合重建临床应用最为广泛，但需要丰富的腔镜手术操作经验及技巧，其操作精细、应用广泛，但存在难度大、耗时长、可靠性低、学习曲线长等缺点。随着腔内切割闭合器及吻合器的发展，在胃肠道吻合手术中得到全面推广，但现有的腔内直线切割闭合器的闭合钉为成排排列，只能整体激发，无法实现精细的单针吻合，因闭合器部件较大，主要用于肠道的吻合重建中，而对于胆道、泌尿系统等精细操作中应用较为困难。同时，在使用直线切割闭合器时需对肠壁切开将闭合器伸入肠腔，吻合后同样需要对肠壁切口进行缝合处理；而管型吻合器手柄粗大，无法实现完全腔镜下吻合，目前主要应用于腔镜的辅助器械或开放手术。At present, the main difficulty in laparoscopic surgery is still the reconstruction operation under the endoscope, such as biliary tract reconstruction, intestinal reconstruction, urinary system reconstruction, etc., and the key points in reconstruction surgery are suturing and knotting. Knotting after needle suture, endoluminal linear cutting closer, and tubular stapler are completed. Suture reconstruction with thread needle is the most widely used clinically, but requires rich experience and skills in laparoscopic surgery. Its operation is fine and widely used. However, there are disadvantages such as difficulty, time-consuming, low reliability, and long learning curve. With the development of endoluminal cutting closers and staplers, they have been fully promoted in gastrointestinal anastomosis. However, the closing nails of the existing endoluminal linear cutting closers are arranged in rows, which can only be stimulated as a whole, and cannot achieve fine precision. The single-needle anastomosis is mainly used in the anastomotic reconstruction of the intestinal tract due to the larger parts of the closer, but it is more difficult to apply it in fine operations such as the biliary tract and the urinary system. At the same time, when using a linear cutting closer, it is necessary to incise the intestinal wall and extend the closure into the intestinal cavity. After anastomosis, the incision in the intestinal wall also needs to be sutured; while the handle of the tubular stapler is thick, it is impossible to achieve a complete endoscopic anastomosis At present, it is mainly used as an auxiliary instrument for laparoscopy or open surgery.
因此，本发明正是基于以上的不足而产生的。Therefore, the present invention just produces based on above deficiency.

【具体实施方式】【Detailed ways】
下面结合附图对本发明作进一步描述：The present invention will be further described below in conjunction with accompanying drawing:
如图2和图3所示，一种缝合器，包括杆体1，所述的杆体1上设有夹钳通道2和装钉通道3，所述的夹钳通道2内设有外露于杆体1并能夹持组织100的夹钳4，所述的装钉通道3内装设有多个能够向前依次运动的缝合钉5，所述的装钉通道3的两侧分别设有与其相通的推钉通道6和上钉通道7，所述的上钉通道7内设有能将装钉通道3内的缝合钉5推送到推钉通道6内的推送部件8，所述的夹钳4钳口位于推钉通道6前端，所述的推钉通道6内设有能将推送部件8推送过来的缝合钉5推入到闭合的夹钳4内，从而使缝合钉5刺入组织100并缝合组织100的推板9。在手术时，首先通过夹钳4夹持住组织100，然后上钉通道7内的推送部件8就将装钉通道3最前端的一个缝合钉5推送到推钉通道6的前端，接着推钉通道6内的推板9就向前推动缝合钉5，缝合钉5的两个脚就触碰夹钳4的钳口，在推板9继续向前顶压的过程中，缝合钉5的两个脚就变形而向内侧刺入到组织100内，并将两层组织缝合到一起，类似订书机订纸张的过程。当推板9向前推缝合钉5的时候，推送部件8回位，装钉通道3内的缝合钉5又向前运动到装钉通道3的前端，为下一次缝合组织做好准备。这样通过不断地夹持、上钉和推钉动作，就能通过多个缝合钉5将组织缝合在一起，提高手术效率，确保手术成功率。As shown in Figures 2 and 3, a stapler includes a rod body 1, and the rod body 1 is provided with a clamp channel 2 and a staple channel 3, and the clamp channel 2 is provided with a The clamp 4 capable of clamping the tissue 100, a plurality of staples 5 that can move forward sequentially are installed in the staple channel 3, and the two sides of the staple channel 3 are respectively provided with push nails communicating with it Channel 6 and nail-on channel 7, the said nail-on channel 7 is provided with a pushing component 8 capable of pushing the staples 5 in the staple channel 3 into the nail-pushing channel 6, and the jaws of the clamp 4 are located at The front end of the push nail channel 6, the staple push channel 6 is provided with a staple 5 that can push the push member 8 into the closed clamp 4, so that the staple 5 penetrates the tissue 100 and sutures the tissue 100 The push plate 9. During the operation, the tissue 100 is first clamped by the clamp 4, and then the pushing part 8 in the staple channel 7 pushes a staple 5 at the front end of the staple channel 3 to the front end of the staple channel 6, and then pushes the staple The push plate 9 in the channel 6 just pushes the staple 5 forward, and the two feet of the staple 5 touch the jaws of the clamp 4. When the push plate 9 continues to press forward, the two pins of the staple 5 touch the jaws of the clamp 4. The first leg is deformed and pierces inwardly into the tissue 100, and the two layers of tissue are stitched together, similar to the process of stapling paper with a stapler. When the push plate 9 pushes the staple 5 forward, the pushing part 8 returns, and the staple 5 in the staple channel 3 moves forward to the front end of the staple channel 3 again, so as to get ready for the next suturing tissue. In this way, by continuously clamping, nailing and pushing the nails, the tissue can be sutured together by a plurality of staples 5, so as to improve the operation efficiency and ensure the success rate of the operation.
如图2所示，所述的夹钳4包括上钳41和与上钳41铰接的下钳42，所述的上钳41上铰接有上连杆43，所述的下钳42上铰接有下连杆44，所述的上连杆43与下连杆44铰接而与上钳41和下钳42构成四连杆机构，并且上连杆43与下连杆43相铰接位置还连接有能推拉二者而使夹钳4钳口张开或闭合的拉杆45。通过推拉拉杆45就能实现上钳41和下钳42的张开或闭合，设计非常的巧妙，动作起来灵活。As shown in Figure 2, the clamp 4 includes an upper jaw 41 and a lower jaw 42 hinged with the upper jaw 41, the upper jaw 41 is hinged with an upper link 43, and the lower jaw 42 is hinged with Lower connecting rod 44, described upper connecting rod 43 is hinged with lower connecting rod 44 and constitutes a four-bar linkage mechanism with upper tongs 41 and lower tongs 42, and the hinged position of upper connecting rod 43 and lower connecting rod 43 is also connected with energy The pull rod 45 that pushes and pulls the two makes the clamp 4 jaws open or close. The opening or closing of the upper tongs 41 and the lower tongs 42 can be realized by pushing and pulling the pull rod 45. The design is very ingenious and the action is flexible.
如图3所示，所述的推送部件8包括能在上钉通道7内横向运动而推动缝合钉5的推送块81，所述的推送块81上设有倾斜的斜面82，所述的上钉通道7内还设有能在其内纵向运动并通过推动所述的斜面82而使推送块81横向运动的推杆83，所述的杆体1与推送块81之间还设有能使推送块81复位的第一复位弹簧84。当推杆83在上钉通道7内向前运动时，推杆83就向前顶推送块81上的斜面82，使得推送块81横向运动，推送块81横向运动时就将装钉通道3前端的一个缝合钉5顶到推钉通道6内的推板9的前方，使得在推板9向前运动时就能将缝合钉5顶到夹钳4内并刺入组织。整个结构设计简单而巧妙。As shown in FIG. 3 , the pushing member 8 includes a pushing block 81 capable of laterally moving in the upper staple channel 7 to push the staples 5 , the pushing block 81 is provided with an inclined slope 82 , and the upper The nail channel 7 is also provided with a push rod 83 that can move longitudinally therein and make the push block 81 move laterally by pushing the inclined surface 82, and a push rod 83 that can push the push block 81 is also provided between the rod body 1 and the push block 81. Block 81 is reset by first return spring 84 . When the push rod 83 moved forward in the nailing passage 7, the push rod 83 pushed the inclined surface 82 on the pushing block 81 forward, so that the pushing block 81 moved laterally, and when the pushing block 81 moved laterally, the front end of the nailing passage 3 was moved forward. A staple 5 is pushed to the front of the push plate 9 in the nail push channel 6, so that when the push plate 9 moves forward, the staple 5 can be pushed into the clamp 4 and penetrate the tissue. The whole structure design is simple and ingenious.
如图2、图6和图9所示，所述的杆体1上设有固定手柄10和能相对固定手柄10转动的活动手柄11，所述的拉杆45上设有凸出的凸出柱12，所述的活动手柄11上设有供凸出柱12插入并在活动手柄11转动时槽壁能推动凸出柱12带着拉杆45在夹钳通道2内滑行的直线槽13，所述的直线槽13的端部还连接有与其相连并能供凸出柱12在内相对滑行的弧形槽14。因此，当活动手柄11转动时，直线槽13的槽壁与拉杆45上的凸出柱12触碰，直线槽13的槽壁就推动凸出柱12向后运动，从而通过凸出柱12带着拉杆45运动，拉杆45运动时就使得上钳41与下钳42相对转动而夹持住组织100。当活动手柄11转动到一定位置时，凸出柱12到达直线槽13与弧形槽14相接位置，由于沿弧形槽14起始端至终止端方向，弧形槽14至活动手柄13转动轴心的距离保持不变，所以当活动手柄13继续转动时凸出柱12就停留在原处，弧形槽14相对凸出柱12动作，此时弧形槽14的槽壁就不再推着凸出柱12动作，拉杆45也不再运动，使得夹钳4对组织保持夹持状态。As shown in Figures 2, 6 and 9, the rod body 1 is provided with a fixed handle 10 and a movable handle 11 that can rotate relative to the fixed handle 10, and the pull rod 45 is provided with a protruding post 12 The movable handle 11 is provided with a linear groove 13 for inserting the protruding column 12 and the groove wall can push the protruding column 12 to slide in the clamp channel 2 with the pull rod 45 when the movable handle 11 is rotated. The end of the linear groove 13 is also connected with an arc-shaped groove 14 which is connected with it and can allow the protruding post 12 to slide relatively therein. Therefore, when the movable handle 11 rotates, the groove wall of the linear groove 13 touches the protruding column 12 on the pull rod 45, and the groove wall of the linear groove 13 just pushes the protruding column 12 to move backward, thereby passing through the protruding column 12. When the pull rod 45 moves, the upper jaw 41 and the lower jaw 42 rotate relatively to clamp the tissue 100 when the pull rod 45 moves. When the movable handle 11 rotates to a certain position, the protruding column 12 reaches the position where the linear groove 13 and the arc groove 14 meet, because along the direction from the beginning end to the end end of the arc groove 14, the rotation axis from the arc groove 14 to the movable handle 13 The distance between the centers remains constant, so when the movable handle 13 continues to rotate, the protruding column 12 just stays in place, and the arc groove 14 moves relative to the protruding column 12, and the groove wall of the arc groove 14 no longer pushes the convex When the output column 12 moves, the pull rod 45 does not move any more, so that the clamp 4 maintains a clamping state on the tissue.
如图5和图6所示，所述的固定手柄10上设有第一竖向槽15，所述的推杆83上设有与其垂直并插入到第一竖向槽15内的推杆竖向段85，所述的活动手柄11上设有在凸出柱12进入到弧形槽14内后才与推杆竖向段85触碰、并在活动手柄11继续转动时推动推杆83在上钉通道7内运动的第一推动柱16，所述的固定手柄10内还设有能使推杆竖向段85复位的第二复位弹簧17。当活动手柄11转动并且凸出柱12在直线槽13内运动时，此过程是夹钳4夹持组织100的过程，在此过程中，活动手柄11上的第一推动柱16不能触碰到推杆竖向段85，此时推杆83就保持不动。当凸出柱12进入到弧形槽14内后，继续转动活动手柄11，此时拉杆45就保持不动，第一推动柱16就推动推杆竖向段85，推杆83就推动推送块81，从而使推送块81将推送一个缝合钉5到推钉通道6内并位于推板9前面。As shown in Figures 5 and 6, the fixed handle 10 is provided with a first vertical groove 15, and the push rod 83 is provided with a vertical push rod vertically inserted into the first vertical groove 15. To the section 85, the movable handle 11 is provided with the protruding post 12 entering the arc groove 14 before it touches the vertical section 85 of the push rod, and pushes the push rod 83 when the movable handle 11 continues to rotate. The first pushing column 16 that moves in the nailing channel 7, and the second return spring 17 that can reset the vertical section 85 of the push rod are also provided in the fixed handle 10 . When the movable handle 11 rotates and the protruding column 12 moves in the linear groove 13, this process is the process of the clamp 4 clamping the tissue 100, and during this process, the first pushing column 16 on the movable handle 11 cannot touch Push rod vertical section 85, now push rod 83 just remains motionless. After protruding column 12 entered in arc groove 14, continue to rotate movable handle 11, and now pull bar 45 just remains motionless, and first push column 16 just pushes push rod vertical section 85, and push rod 83 just pushes push block 81, so that the pushing block 81 will push a staple 5 into the nail pushing channel 6 and be positioned in front of the pushing plate 9.
如图7和图8所示，所述的固定手柄10上设有第二竖向槽20，所述的推板9上设有与其垂直并插入到第二竖向槽20内的推板竖向段21，所述的活动手柄11上设有在推杆83将缝合钉5推送到推钉通道6内后才与推板竖向段21触碰、并在活动手柄11继续转动时推动推板9在推钉通道6内运动的第二推动柱22，所述的固定手柄10内还设有能使推板竖向段21复位的第三复位弹簧23。当活动手柄11转动并且第一推动柱16推动推杆竖向段85动作时，此过程是推杆83通过推送块81推动缝合钉5到推钉通道6内的过程，在此过程中，活动手柄11上的第二推动柱22不能触碰到推板竖向段21，此时推板9不动。当缝合钉5被推送块81推到推钉通道6内时，第一推动柱16到达与活动手柄11转动轴心最远的位置，此时继续转动活动手柄11时，第一推动柱16将不再能推动推杆竖向段85动作。此时第二推动柱22触碰到推板竖向段21，并在推动推板竖向段21的过程中使推板9向前运动，推板9向前运动就将缝合钉5顶到夹钳4内，并使缝合钉5的两支脚变形而刺入到组织内缝合组织。所以，当活动手柄11转动的过程中实现三个动作，首先活动手柄11转动一定角度时实现夹钳4夹紧组织的动作，接着活动手柄11继续转动一定角度时实现缝合钉5被推入推钉通道6的动作，再接着活动手柄11继续转动一定角度时实现推板9推动缝合钉5缝合组织的动作。所以一次转动活动手柄11就实现组织的一次缝合，操作非常的简单快捷。当缝合钉5刺入组织并缝合以后，活动手柄11回转复位，推板9、推杆83均复位，装钉通道3内的缝合钉5又向前运动。接着移动杆体1到组织的另外一个位置，并重复相同的动作而刺入缝合钉5。以此类推，就可以在组织上钉上一排缝合钉5，使组织得以完全缝合。As shown in Figures 7 and 8, the fixed handle 10 is provided with a second vertical groove 20, and the push plate 9 is provided with a vertical push plate vertically inserted into the second vertical groove 20. To the section 21, the movable handle 11 is provided with a push rod 83 that pushes the staple 5 into the push nail channel 6 before touching the vertical section 21 of the push plate, and pushes the push plate when the movable handle 11 continues to rotate. The second push column 22 for the plate 9 to move in the push nail channel 6, and the third return spring 23 for resetting the vertical section 21 of the push plate is also provided in the fixed handle 10 . When the movable handle 11 rotates and the first push column 16 pushes the vertical section 85 of the push rod to move, this process is the process in which the push rod 83 pushes the staple 5 into the push nail passage 6 through the push block 81, during which the movable The second push column 22 on the handle 11 cannot touch the vertical section 21 of the push pedal, and the push pedal 9 does not move at this moment. When the staples 5 are pushed into the pusher channel 6 by the pushing block 81, the first pushing column 16 reaches the position farthest from the axis of rotation of the movable handle 11. The vertical section 85 of the push rod can no longer be promoted to act. Now the second push column 22 touches the vertical section 21 of the push pedal, and in the process of pushing the vertical section 21 of the push pedal, the push pedal 9 is moved forward, and the forward movement of the push pedal 9 pushes the staples 5 to the top Inside the clamp 4, and make the two legs of the staple 5 deform and penetrate into the tissue to suture the tissue. Therefore, three actions are realized during the rotation of the movable handle 11. First, when the movable handle 11 rotates at a certain angle, the clamp 4 clamps the tissue, and then when the movable handle 11 continues to rotate at a certain angle, the staple 5 is pushed in. The action of the nail channel 6, and then the movable handle 11 continues to rotate at a certain angle to realize the action that the push plate 9 pushes the staples 5 to sew the tissue. Therefore, once the movable handle 11 is rotated, one suture of the tissue is realized, and the operation is very simple and quick. After the staple 5 penetrates into the tissue and is sutured, the movable handle 11 turns and resets, the push plate 9 and the push rod 83 all reset, and the staple 5 in the staple channel 3 moves forward again. Then move the rod body 1 to another position of the tissue, and repeat the same action to puncture the staple 5 . By analogy, a row of staples 5 can be nailed on the tissue, so that the tissue can be completely sutured.
如图10所示，所述的装钉通道3内设有能使缝合钉5依次向前运动的顶钉板24，所述的装钉通道3内设有能推动顶钉板24运动而顶钉的顶钉弹簧25。当装钉通道3内装满缝合钉5时，顶钉弹簧25是压缩的，当装钉通道3内的缝合钉5每进入一个到推钉通道6内时，顶钉弹簧25就伸长一定，并通过顶钉板24使得缝合钉5向前运动到推送块81的位置，为下一次上钉做好准备。As shown in FIG. 10 , the staple channel 3 is provided with a top nail plate 24 that can move the staples 5 forward sequentially. The top nail spring 25 of the nail. When the staple channel 3 was filled with staples 5, the top nail spring 25 was compressed, and when the staples 5 in the staple channel 3 entered one into the push nail channel 6, the top nail spring 25 would elongate by a certain amount. , and make the staple 5 move forward to the position of the pushing block 81 through the top nail plate 24, and get ready for the next nailing.
当然，本发明推送缝合钉还可以采用另外一种结构方式，如图11所示，所述的固定手柄10上设有中部与其铰接的扳动手柄18，所述的扳动手柄18上端与推杆83铰接，并且在扳动手柄18转动时所述的扳动手柄18上端驱动推杆83在上钉通道7内运动,所述的扳动手柄18与固定手柄10之间还设有推动扳动手柄18复位的第三复位弹簧19。在实际手术操作时，拇指和无名指可以操作固定手柄10和活动手柄11，而食指就可以操作扳动手柄18，通过扣动扳动手柄18使得推杆83动作而上钉。Of course, another structure can be adopted for pushing the staples in the present invention. As shown in FIG. The rod 83 is hinged, and when the pull handle 18 is rotated, the upper end of the pull handle 18 drives the push rod 83 to move in the nailing channel 7, and a push pull handle is also provided between the pull handle 18 and the fixed handle 10. The third back-moving spring 19 that moves the handle 18 to reset. During actual operation, the thumb and ring finger can operate the fixed handle 10 and the movable handle 11, while the index finger can operate the pull handle 18, and the push rod 83 can be driven to perform nailing by pulling the pull handle 18.
