钉仓组件Cartridge Components

技术领域technical field

本发明涉及一种外科手术装订器械的钉仓组件，属于医疗器械技术领域。The invention relates to a staple cartridge assembly of a surgical operation binding instrument, which belongs to the technical field of medical instruments.

背景技术Background technique

外科手术装订器械是用于外科手术中进行伤口缝合的重要工具，目前已有淘汰手工缝合的趋势。其中，直线型/弧线型装订器械可以进行伤口组织的闭合，直线型切割装订器械可以在进行伤口组织闭合的同时进行组织切割，圆管型切割装订器械可以进行圆管型组织的缝合和切割。Surgical binding instruments are an important tool for wound suturing in surgical operations, and there is a trend of eliminating manual suturing at present. Among them, the linear/curved binding instrument can close the wound tissue, the linear cutting and binding instrument can cut the tissue while closing the wound tissue, and the round tube cutting and binding instrument can suture and cut the round tube tissue .

以美国专利US7055730揭示的直线型切割装订器械为例，这种装订器械可以同时在组织的两侧各击入两排吻合钉，然后用推刀在两侧已缝合好的组织之间进行切割离断。目前临床广泛应用这种缝合器进行胃、空肠侧侧吻合，以及胃管的制作、肺部分切除等手术。其优点在于缝合长度长，可以在缝合组织的同时进行组织切割。其中器械包括上下两个钳夹及一个闭合把手，上下两个钳夹其中之一上设有钉仓，另一个相对设有钉砧，将组织放置在钉仓和钉砧之间，然后将闭合把手合上，组织就被夹紧在上、下闭合钳夹之间，然后推动推钉杆和推刀杆，就可完成组织的钉合与分离。Take the linear cutting and binding instrument disclosed in US Pat. broken. At present, this stapler is widely used clinically for side-to-side anastomosis of the stomach and jejunum, as well as operations such as the production of gastric tubes and partial lung resection. The advantage is that the suture length is long, and tissue cutting can be performed while suturing the tissue. The instrument includes two upper and lower jaws and a closing handle. One of the upper and lower jaws is provided with a staple cartridge, and the other is relatively provided with an anvil. The tissue is placed between the staple cartridge and the staple anvil, and then the closed When the handle is closed, the tissue is clamped between the upper and lower closed jaws, and then the nail pushing rod and the knife pushing rod are pushed to complete the stapling and separation of the tissue.

目前的外科手术装订器械使用过程中，普遍存在击发力较大的问题，特别是直线型切割装订器械，出钉的方向与击发力的施加方向不同，击发力较大的问题更加突出。导致击发力大的因素很多，机构复杂可导致击发力大，各个配合零件间的摩擦力大亦可导致击发力大。由于击发力大，医生在使用过程中容易出现疲劳感。In the current use of surgical binding instruments, there is a common problem of large firing force, especially for linear cutting and binding instruments, the direction of nail output is different from the direction of firing force, and the problem of large firing force is more prominent . There are many factors that lead to a large firing force. The complex mechanism can lead to a large firing force, and the large frictional force between various matching parts can also cause a large firing force. Due to the high firing force, doctors are prone to fatigue during use.

如图1和图2所示，该器械的钉仓组件100包括钉仓1，设于钉仓1表面的钉仓孔2，置于钉仓孔2内的缝合钉及推钉片3。由于钉仓孔2与推钉片3为轮廓相同的六边形，所以两者之间的摩擦力很大，导致器械的击发力也很大。As shown in FIGS. 1 and 2 , thecartridge assembly 100 of the instrument includes acartridge 1 , acartridge hole 2 disposed on the surface of thecartridge 1 , staples placed in thecartridge hole 2 and astaple pusher 3 . Since thestaple cartridge hole 2 and thepusher plate 3 have the same hexagonal profile, the frictional force between them is very large, resulting in a large firing force of the instrument.

具体实施方式Detailed ways

本发明揭示了一种钉仓组件100，适用于直线型/弧线型装订器械、直线型切割装订器械、圆管型切割装订器械。The present invention discloses astaple cartridge assembly 100, which is suitable for linear/curved binding instruments, linear cutting and binding instruments, and round tube cutting and binding instruments.

如图1所示，与现有技术一致，钉仓组件100包括钉仓1，设于钉仓1表面的钉仓孔2，置于钉仓孔2内并可与之相对滑动的缝合钉及推钉片3。有的器械中，所述推钉片3还可以固定在同一个推钉片座4上。As shown in FIG. 1, consistent with the prior art, thestaple cartridge assembly 100 includes astaple cartridge 1, astaple cartridge hole 2 disposed on the surface of thestaple cartridge 1, a staple and a staple that are placed in thestaple cartridge hole 2 and can slide relative thereto. Pushnail piece 3. In some instruments, thenail pusher 3 can also be fixed on the samenail pusher seat 4 .

本发明中，所述钉仓孔2和推钉片3的横截面均包括有一对长边7、8。结合图3所示的第一实施例，所述钉仓孔2的长边7之间的距离L大于所述推钉片3的长边8之间的距离D。而所述钉仓孔2的长边7之间的连接段包括一圆角5，所述推钉片3的长边8之间的连接段包括一圆角6，所述推钉片的圆角6与所述钉仓孔的圆角5相内切。这样，所述钉仓孔2和推钉片3仅仅是两端的点接触，摩擦力大大变小。In the present invention, the cross-sections of thecartridge hole 2 and thepush piece 3 both include a pair oflong sides 7 , 8 . With reference to the first embodiment shown in FIG. 3 , the distance L between thelong sides 7 of thecartridge holes 2 is greater than the distance D between thelong sides 8 of thepusher pieces 3 . And the connection section between thelong sides 7 of the describednail bin hole 2 includes arounded corner 5, the connection section between thelong sides 8 of the describednail pushing piece 3 includes arounded corner 6, and the circle of the describednail pushing piece 3 includes a rounded corner. Thecorner 6 is inscribed with therounded corner 5 of the cartridge hole. Like this, describednail bin hole 2 andnail pushing plate 3 are only the point contact of two ends, and frictional force is greatly reduced.

进一步地，所述钉仓孔和推钉片的横截面均可以设置成与现有技术相同的六边形，所述长边7、8可为其一对边。当然，其他的形状也不排除在本发明之外。Further, the cross-sections of the staple cartridge hole and the push piece can both be set as the same hexagon as in the prior art, and thelong sides 7 and 8 can be a pair of sides. Of course, other shapes are not excluded from the present invention.

由于2点接触不是太稳固，所示图4所示的第二实施例中，所述钉仓孔2的长边7上均设有一凹口9，所述凹口9之间的最短距离D等于所述推钉片3的长边8之间的距离D。所示图5所示的第三实施例中，所述推钉片3的长边8上均设有一凸起10，所述凸起10之间的最长距离等于所述钉仓孔2的长边8之间的距离。Because the two-point contact is not too stable, in the second embodiment shown in Figure 4, a notch 9 is provided on thelong side 7 of thestaple cartridge hole 2, and the shortest distance D It is equal to the distance D between thelong sides 8 of thepush piece 3 . In the third embodiment shown in FIG. 5 , a protrusion 10 is provided on thelong side 8 of thenail pushing piece 3 , and the longest distance between the protrusions 10 is equal to that of thestaple cartridge hole 2 . The distance between thelong sides 8.

这样形成的多点接触，会保证减小摩擦力的前提下，又能达到稳固推钉片的作用。The multi-point contact formed in this way can ensure the effect of stabilizing the push nail under the premise of reducing the friction force.

本发明尚有多种实施方式，例如波浪面点接触，折线形点接触等，凡采用等同变换或者等效变换而形成的所有技术方案，均落在本发明的保护范围之内。The present invention still has many implementations, such as wave surface point contact, broken line point contact, etc. All technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present invention.
