Description

圆管型外装订仪 技术领域  Round tube type outer binding instrument
本发明涉及实施肠道吻合等外科手术所使用的装订仪,特别为一 种圆管型外装订仪, 属于医疗器械技术领域。  The invention relates to a binding device used for performing surgical operations such as intestinal anastomosis, in particular to a round tube type external binding instrument, belonging to the technical field of medical instruments.

Its function is to staple and bind a physiological tissue such as a cut intestinal tract, so that the post-operative tissue can restore physiological functions. The difference in the performance of the stapler plays a crucial role in both the surgical procedure and the surgical outcome. In the prior art, there are many types of binding devices, and according to the position classification of the post-surgery binding mouth, the binding device is divided into two categories: an inner binding device and an outer binding device; according to the shape of the post-surgery binding port, there is a round tube type binding device. , linear binding machine and other varieties.
目前国内外医疗器械行业对圆管型内装订仪研究得比较深入,新 产品、新技术不断出现。但这种装订仪存在两大方面先天不足, 一是 需要在装订口附近开设贲门, 二是装订口金属环滞留在组织内腔当 中, 既妨碍术后取出医疗器械,又影响到术后机体组织恢复功能。尽 管人们通过技术改进,采用扩张内吻合等方式对上述第二种缺陷有所 弥补, 但第一种缺陷仍是不可避免的。  At present, the medical device industry at home and abroad has made in-depth research on the round tube type internal binding instrument, and new products and new technologies are constantly appearing. However, there are two major disadvantages in this type of binding device. One is the need to open a cardia near the binding mouth. The other is that the metal ring of the binding mouth stays in the lumen of the tissue, which hinders the removal of medical devices after surgery and affects the recovery of the body after surgery. Features. Although the above-mentioned second defects are compensated by technical improvement and expansion and internal anastomosis, the first defect is still inevitable.

The hole 30, the positioning rib 29 is provided with a retaining groove 32 of the joint head on both sides thereof, and the pin 31 passes through the joint of the inner sleeve 7 and the binding hole 30 of the push rod 8 to connect them integrally. After the front half portion and the rear half portion are respectively assembled, the inner fixing sleeve 7 is sleeved on the front end boss 14 of the fixed body 1, and the half ring of the inner fixing sleeve 7 is locked on the boss 14 through the locking hole.
内圈结构当中, 钉子成形槽按照以下方法安装: 先把四只外圈成 形槽 17按照其上的铰接头 19和铰接孔 20用销两两串连起来形成一 个圆环, 并留有一开口处, 便于手术结束后打开。该圆环通过四个外 圈成形槽 17外侧的导槽柱 21落入内固定套 7末端的槽中而定位,圆 环的头尾连接处保持活动开口而不用销固定,以便圆环的直径可以适 当调节,并且使外圈成形槽 17上的斜面 18压在推槽杆 8的前端斜面 上; 内圈成形槽 16包括有四小块, 各小块分别用弹簧丝连接在推槽 杆 8的外表面的前端斜面上, 并紧压着外圈成形槽 17外表面的凹台 上, 成环状套在推槽杆 8上, 与推槽杆 8之间通过相互匹配的柱、槽 而定位。  In the inner ring structure, the nail forming groove is installed as follows: First, the four outer ring forming grooves 17 are connected by a pair of pins 19 and a hinge hole 20 to form a ring, and an opening is left. , easy to open after the end of surgery. The ring is positioned by the guide groove 21 outside the four outer ring forming grooves 17 falling into the groove at the end of the inner fixing sleeve 7, and the head and tail joints of the ring are kept in the movable opening without pin fixing, so that the diameter of the ring It can be appropriately adjusted, and the inclined surface 18 on the outer ring forming groove 17 is pressed against the front inclined surface of the pushing rod 8; the inner ring forming groove 16 includes four small pieces, each of which is connected to the pushing rod 8 by a spring wire. The front surface of the outer surface of the outer surface is pressed against the concave surface of the outer surface of the outer ring forming groove 17, and is annularly sleeved on the pushing rod 8 and passes through the matching columns and grooves between the pushing rod 8 and the grooved rod 8 Positioning.
钉子成形槽装配完成之后, 便成为一组完整的内圈组件。 其中, 在让位槽 32的配合下, 推槽杆 8可以独自周向旋转, 旋转到位后再 和内固定套 7同步进行周向开合; 在销杆 31的导向下, 推槽杆 8可 以沿轴向与内固定套 7作相对移动。当推槽杆 8横向移动时,与外圈 成形槽 17、 内圈成形糟 16的斜面发生作用, 使外圈成形槽 17、 内圈 成形糟 16形成的圆环的直径同时得到相应程度的扩张。 Once the nail forming slot is assembled, it becomes a complete set of inner ring components. Wherein, under the cooperation of the positioning groove 32, the pushing rod 8 can be rotated circumferentially by itself, and then rotated into position, and then opened and closed in synchronization with the inner fixing sleeve 7; under the guidance of the pin 31, the pushing rod 8 can be The relative movement of the inner fixing sleeve 7 is performed in the axial direction. When the grooving rod 8 is laterally moved, it acts on the inclined surface of the outer ring forming groove 17 and the inner ring forming slag 16, so that the diameter of the ring formed by the outer ring forming groove 17 and the inner ring forming dam 16 is simultaneously expanded to a corresponding extent. .
装配外圈组件时, 先装配外圈结构的一半: 在放钉孔 25内部放 入装订钉, 对准推钉槽 24, 在半环状钉筒套管 9的前端分别插入内 圈推钉片 22和外圈推钉片 23, 并分别在内圈推钉片 22、外圈推钉片 23与钉筒套管 9上的推钉槽 24之间添加弹性钢丝; 再在钉筒套管 9 的外部套入半环状推钉杆 10, 使两者的预留孔 15对齐。 此时, 推钉 杆 10的内侧与钉筒套管 9外表面的加强筋 39接触, 推钉杆 10前端 的内斜面 40压在内圈推钉片 22和外圈推钉片 23之上。 接着把外套 管 11从钉筒套管 9的前端套入, 使预留孔及锁紧孔对齐, 并在封头 41的锁紧孔 37内装上锁紧螺钉, 使外套管 11固定在钉筒套管 9上 面。类似地, 按上面方法装配好另外一半外圈组件, 再把两只半环状 外圈组件按照其上面设置的铰接头配对好, 插入销轴 28, 使之成为 可以打幵且合起时是完整的圆环状的外圈组件。  When assembling the outer ring assembly, first assemble half of the outer ring structure: insert a binding staple inside the nail hole 25, align the push pin groove 24, and insert the inner ring push pin piece at the front end of the semi-annular nail cannula 9 22 and the outer ring pushing the nail piece 23, and respectively adding an elastic steel wire between the inner ring pushing nail piece 22, the outer ring pushing nail piece 23 and the nail pushing groove 24 on the nail sleeve 9; and then in the nail sleeve 9 The outer sleeve is inserted into the semi-annular pusher bar 10 to align the reserved holes 15 of the two. At this time, the inner side of the pusher bar 10 is in contact with the rib 39 on the outer surface of the cartridge sleeve 9, and the inner slope 40 of the front end of the pusher bar 10 is pressed against the inner ring pusher piece 22 and the outer ring pusher piece 23. Then, the outer sleeve 11 is inserted from the front end of the sleeve 9 to align the reserved hole and the locking hole, and a locking screw is installed in the locking hole 37 of the head 41 to fix the outer sleeve 11 to the nail tube. Above the casing 9. Similarly, the other half of the outer ring assembly is assembled as described above, and the two semi-annular outer ring assemblies are paired according to the joints provided thereon, and the pin 28 is inserted so that it can be smashed and assembled. Complete annular outer ring assembly.
整体装配:把装配好的外圈组件打开,使之包在内圈组件的外围, 然后再合上, 并使钉筒套管 9后端内侧的导向槽 27与固定套管 3上 的导向花键 12配合。 接着, 从内圈组件的尾部套入外固定套 6, 使 其内部的定向槽口 38与钉筒套管 9上的筋配合; 从装订仪尾部套入 锁套 5, 使锁套 5内部的槽口也与固定套管 3上的导向花键 12配合; 套入 U型把手 33, 使把手 33两端的锁紧杆 34穿入锁套 5上面的孔 中,把手 33两端的推进凸台 35进入到外固定套 6的槽口中; 再推动 把手 33及锁套 5, 带动外圈组件整体和外固定套 6在导向花键 12上 朝前端滑移。 当钉筒套管 9尾部的定位台阶 26与固定体 1的止步台 阶 13相抵触时, 把手 33上面的锁紧杆 34滑入固定套管 3相应的锁 紧孔 36当中, 锁死外圈组件及外固定套 6等部件。 最后, 在装订仪 的尾部旋上旋钮 4, 完成装订仪的整体装配。 本发明在使用时,先搬开 U型把手 33, 使把手 33上的锁紧杆 34 脱离固定套管 3。 整体向后移动外圈组件, 使内圈组件前端的成型槽 区域外露, 把待装订的肠子(或其它组织)的一端从装配好的装订仪 的预留口 15穿入, 直至内圈组件头部, 向外翻折肠管使之伏在内、 外圈成型槽 16、 17上, 再把另一端肠子覆盖在已套好的肠子之上, 然后向前推动把手 33及锁套 5, 带动外固定套 6和整体外圈组件在 导向花键 12上滑移。 Overall assembly: the assembled outer ring assembly is opened to be wrapped around the outer ring assembly, and then closed, and the guide groove 27 on the inner side of the rear end of the sleeve 9 and the guide flower on the fixed sleeve 3 The key 12 is matched. Next, the outer fixing sleeve 6 is inserted from the tail of the inner ring assembly, and the inner directional notch 38 is engaged with the rib on the sleeve 9; the locking sleeve 5 is inserted from the tail of the binding device to make the inside of the locking sleeve 5 The notch also cooperates with the guide spline 12 on the fixed sleeve 3; the U-shaped handle 33 is fitted, and the locking rod 34 at both ends of the handle 33 is inserted into the hole in the upper surface of the lock sleeve 5, and the push boss 35 at both ends of the handle 33 Enter into the notch of the outer fixing sleeve 6; push again The handle 33 and the lock sleeve 5 drive the outer ring assembly as a whole and the outer sleeve 6 to slide toward the front end on the guide spline 12.
