自动荷包缝合器Automatic Purse Stapler

技术领域technical field

本发明涉及一种荷包缝合器，尤其是一种自动荷包缝合器，属于医疗器械领域。The invention relates to a purse-string suturing device, in particular to an automatic purse-string suturing device, which belongs to the field of medical devices.

背景技术Background technique

外科用荷包缝合器是对肠道等生理组织进行外科手术时经常使用的一种医疗器械，该仪器性能的好坏直接影响手术进程，对于手术效果起着非常重要的作用。现有技术中，使用装订仪进行缝合手术时都要在器官残端做荷包缝合，以便在置入中心杆后能牢固结扎，然后才能实施装订手术。实施荷包缝合手术的方法有两种：一种是手工缝合，不仅操作极为费时费力，而且进针有深有浅，针距也不一致；另一种是使用荷包缝合钳，以针带线一起穿过夹有组织的钳口进行荷包缝合，缺点是需要用针穿过钳口的一个小孔，操作不方便。Surgical purse-string suturing device is a medical device often used in surgical operations on intestinal and other physiological tissues. The performance of the instrument directly affects the operation process and plays a very important role in the operation effect. In the prior art, when using a stapler for suturing, purse-string sutures must be performed on the stump of the organ, so that it can be firmly ligated after the central rod is inserted, and then the stapler can be implemented. There are two methods of performing purse-string suture surgery: one is manual suture, which is not only time-consuming and labor-intensive, but also the depth of the needle is different, and the needle pitch is inconsistent; the other is to use purse-string suture forceps to thread the needle with thread Purse string suture is carried out by clipping organized jaws, but the disadvantage is that a needle needs to pass through a small hole in the jaws, which is inconvenient to operate.

应运而生的自动荷包缝合器，在较大程度上解决了上述问题，美国专利US4821939记载了一种自动荷包缝合器，其由把手夹座与钉仓组件组成，两个把手夹座交叉组成剪刀状结构，钉仓组件内有钉、推钉片及荷包线。当夹紧上、下两个把手后，钉仓内的钉就被击发出来，把荷包线固定在组织外壁，然后就可以收紧荷包线扎荷包了。可以看到，制作荷包的过程非常简单、省时，但是因为扎荷包本身是手术中的一个很小的部分，而这样一把自动荷包器的价格却不菲，对于病人来说经济负担加重。The automatic purse-string stapler that emerged at the historic moment has solved the above problems to a large extent. US Patent No. 4,821,939 describes an automatic purse-string stapler, which consists of a handle holder and a staple cartridge assembly, and two handle holders cross to form scissors. Shaped structure, there are nails, nail pushers and purse wires in the nail cartridge assembly. When the upper and lower handles are clamped, the nails in the staple magazine are fired out, fixing the purse wire to the outer wall of the tissue, and then the purse wire can be tightened to bind the purse. It can be seen that the process of making a purse is very simple and time-saving, but since the pouch itself is a very small part of the operation, and such an automatic purse is expensive, it will increase the financial burden on the patient.

本发明将此专利所记载的内容作为现有技术进行引用。The present invention cites the content described in this patent as prior art.

具体实施方式Detailed ways

本发明揭示了一种自动荷包缝合器，如图1-图4所示，包括：上、下外壳1、2，及设置在外壳内部的钉仓组件，所述的钉仓组件包括钉仓4、及置于钉仓4内的推钉片5和钉6。本发明的钉仓组件与现有技术相同，不同的是在初始状态时所述的上外壳1和下外壳2的一端呈枢轴连接且呈锐角设置，在工作过程中上外壳1相对于下外壳2转动并使两者达到相互大致平行后，所述的上外壳1和下外壳2可相对运动使推钉片5将钉6推出钉仓4外。与现有技术相比，本发明的外壳小巧许多，制造方便并且节省了大量的原材料。The present invention discloses an automatic purse-string stapler, as shown in Figures 1-4, comprising: upper andlower shells 1, 2, and a staple cartridge assembly disposed inside the shell, the staple cartridge assembly includes astaple cartridge 4 , and thenail pusher 5 and thenail 6 placed in thenail bin 4. The staple cartridge assembly of the present invention is the same as the prior art, except that in the initial state, one end of theupper shell 1 and thelower shell 2 is pivotally connected and arranged at an acute angle. After theshell 2 is rotated and made to be substantially parallel to each other, theupper shell 1 and thelower shell 2 can move relative to each other so that thenail pushing piece 5 pushes thenail 6 out of thenail bin 4 . Compared with the prior art, the shell of the present invention is much smaller, convenient to manufacture and saves a lot of raw materials.

进一步地参照图1和图2，所述的下外壳2的一端有枢轴孔7，该枢轴孔7内紧配合有一销轴3，所述的销轴3穿过设置在上外壳1一端的滑动槽8，所述的销轴3可在滑动槽8内转动或滑动。Referring further to Fig. 1 and Fig. 2, one end of thelower shell 2 has apivot hole 7, and apin shaft 3 is tightly fitted in thepivot hole 7, and thepin shaft 3 passes through one end of theupper shell 1 Thesliding groove 8, thepin shaft 3 can rotate or slide in thesliding groove 8.

所述的滑动槽8的形状类似于钥匙孔的形状，包括圆孔部分和长槽部分，两者结合在一起。所述的销轴3可在圆孔部分内转动、可在长槽部分内滑动。The shape of thesliding groove 8 is similar to that of a keyhole, including a round hole part and a long groove part, and the two are combined together. Thepin shaft 3 can rotate in the circular hole and slide in the slot.

所述的销轴3包括有两个相对的圆弧面部分31和两个相对的平面部分32，所述的平面部分32之间的距离小于圆弧面部分31的直径，所述的销轴3的圆弧面部分31与枢轴孔7紧配合。由于本优选实施例中，所述的滑动槽8的长槽部分的宽度小于所述的销轴3的圆弧面部分31的直径，且又大于所述的销轴3的平面部分32之间的距离，所以只有当销轴3的平面部分32与滑动槽8的长槽部分相对时，销轴3才能滑入滑动槽8的长槽部分且在其内滑动。Thepin shaft 3 includes two oppositearc surface parts 31 and twoopposite plane parts 32, the distance between theplane parts 32 is smaller than the diameter of thearc surface part 31, and the pin shaft Thearc surface part 31 of 3 is closely fitted with thepivot hole 7. Because in this preferred embodiment, the width of the long groove part of thesliding groove 8 is smaller than the diameter of thearc surface part 31 of thepin shaft 3, and is larger than the diameter between theplane parts 32 of thepin shaft 3. distance, so only when theplane portion 32 of thepin shaft 3 is opposite to the long groove portion of thesliding groove 8, thepin shaft 3 can slide into the long groove portion of thesliding groove 8 and slide therein.

再进一步地，所述的上、下外壳1、2表面设置有防滑装置9。所述的防滑装置9为粘在上、下外壳1、2表面的防滑软胶或设置在上、下外壳1、2表面的防滑纹。Still further, ananti-slip device 9 is provided on the surfaces of the upper andlower casings 1 and 2 . Theanti-slip device 9 is soft anti-slip glue sticking to the surfaces of the upper andlower casings 1 and 2 or anti-slip lines arranged on the surfaces of the upper andlower casings 1 and 2 .

再进一步地，所述的上、下外壳1、2之间设置有扭簧，用以防止上、下外壳1、2在初始状态时转动，进而相互挤压引起推钉片5向外运动把钉6推出钉仓4，造成整个器械的失效。Furthermore, a torsion spring is provided between the upper andlower shells 1, 2 to prevent the upper andlower shells 1, 2 from rotating in the initial state, and then squeeze each other to cause thepusher piece 5 to move outwards. Thenail 6 is pushed out of thenail bin 4, causing the failure of the whole device.

下面参照图5、图6、图7介绍一下本发明的使用过程：Below with reference to Fig. 5, Fig. 6, Fig. 7 introduce the use process of the present invention:

本发明在使用前，先将上、下钉仓4装入钉6与推钉片5，并且将荷包线装入到钉仓4内，然后将钉仓组件分别装入上、下外壳1、2内。将组织放在上、下钉仓的缝合区域内，然后闭合上、下外壳1、2的另一端，即：使上外壳1相对于下外壳2转动。此时，由于销轴3的圆弧面部分31与枢轴孔7紧配合，在上外壳1相对于下外壳2转动过程中，始终是销轴3的圆弧面部分31与滑动槽8的长槽部分相对，确保上外壳1相对于下外壳2在转动过程中不能被压下而相互运动。Before using the present invention, the upper andlower staple cartridges 4 are first loaded into thenails 6 and thenail pushers 5, and the purse wire is loaded into thestaple cartridge 4, and then the staple cartridge components are respectively loaded into the upper andlower shells 1, 2 within. The tissue is placed in the suturing area of the upper and lower staple cartridges, and then the other ends of the upper andlower shells 1, 2 are closed, that is, theupper shell 1 is rotated relative to thelower shell 2. At this time, since thearc surface portion 31 of thepin shaft 3 is tightly fitted with thepivot hole 7, during the rotation process of theupper shell 1 relative to thelower shell 2, thearc surface portion 31 of thepin shaft 3 is always in contact with theslide groove 8. The long grooves are partially opposite to each other to ensure that theupper shell 1 cannot be pressed down and move relative to thelower shell 2 during the rotation process.

当上外壳1与下外壳2转动到两者达到相互大致平行时，销轴3的平面部分32与滑动槽8的长槽部分相对时，此时用力捏住上、下外壳1、2的两端，销轴3滑入滑动槽8的长槽部分且在其内滑动。此时，与现有技术一样，上、下外壳1、2相对运动，上、下外壳1、2内的钉仓4会向上、下外壳1、2内部运动，相对的推钉片5就将钉6从钉仓4内击发出来，钉6刺入组织的同时将荷包线置在钉与组织之间。将自动荷包器撤离，然后收紧荷包线，即完成了荷包缝合。When theupper shell 1 and thelower shell 2 are rotated until the two are approximately parallel to each other, when theplane part 32 of thepin shaft 3 is opposite to the long groove part of theslide groove 8, at this moment, firmly pinch the two sides of the upper andlower shells 1 and 2. end, thepin shaft 3 slides into the long groove part of thesliding groove 8 and slides therein. Now, as in the prior art, the upper andlower shells 1 and 2 relatively move, and thestaple bins 4 in the upper andlower shells 1 and 2 move upwards and inside thelower shells 1 and 2, and therelative nail pushers 5 will move Thenail 6 is driven out from thenail magazine 4, and the purse string is placed between the nail and the tissue while thenail 6 penetrates the tissue. Withdraw the automatic purse device, and then tighten the purse string, which completes the purse suture.

本发明尚有多种具体的实施方式。凡采用等同替换或者等效变换而形成的所有技术方案，均落在本发明要求保护的范围之内。The present invention still has multiple specific implementation modes. All technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
