技术领域technical field
本发明涉及一种外科手术器械，特别为一种直线型缝切器，属于医疗器械技术领域。The invention relates to a surgical instrument, in particular to a linear slit cutter, which belongs to the technical field of medical instruments.
背景技术Background technique
直线型缝切器被广泛用于外科手术中用于伤口缝合、内部组织缝合与切割，典型的直线型缝切器如美国专利US5129570所揭示，具有缝合与切割两个功能，在进行伤口缝合的同时，将多余的组织切除。该类直线型缝切器一般包括上、下两个钳夹，以及用于闭合上、下钳夹的闭合把手，相对设置在上、下钳夹远端的钉砧和钉仓，设于钉仓内并可同时相对所述钉仓移动的击发片和切刀，以及用于驱动所述击发片和切刀移动的推钮。所述钉仓内排列设置有缝合钉，所述击发片依次按顺序推动推钉片并将缝合钉推向钉砧，所述切刀将位于钉仓和钉砧之间的组织切断。Linear sewing cutters are widely used in surgical operations for wound suturing, internal tissue suturing and cutting. Typical linear sewing cutters, as disclosed in U.S. Patent No. 5,129,570, have two functions of suturing and cutting. At the same time, excess tissue is removed. This type of linear seam cutter generally includes upper and lower jaws, and a closing handle for closing the upper and lower jaws. A firing piece and a cutter in the magazine that can move relative to the staple cartridge at the same time, and a push button for driving the movement of the firing piece and the cutting knife. Staples are arranged in the staple cartridge, the firing piece sequentially pushes the staple pushers and pushes the staples to the anvil, and the cutter cuts off the tissue located between the staple cartridge and the anvil.
现有的直线型缝切器上的钉仓架上设有一个金属材质的限位凸起，该限位凸起与闭合把手接触，从而对闭合把手实现限位。但是目前普遍使用的直线型缝切器上，限位凸起与闭合把手的接触为线接触，并且是金属与金属的直接接触。当直线型缝切器打开时，接触比较生硬，导致使用者手感不好。The staple cartridge rack on the existing linear seam cutter is provided with a metal limiting protrusion, and the limiting protrusion is in contact with the closing handle so as to limit the closing handle. However, on the linear seam cutter generally used at present, the contact between the limit protrusion and the closing handle is a line contact, and it is a direct contact between metal and metal. When the linear seam cutter is opened, the contact is relatively stiff, causing the user to feel bad.

一种直线型缝切器，包括相对设置的钉砧和钉仓，所述钉仓设于一钉仓架内，所述钉仓架与闭合把手枢轴连接，所述钉仓架上靠近所述闭合把手处设有限位凸起，所述限位凸起外部设有一缓冲套。A linear seam cutter, comprising an anvil and a staple cartridge oppositely arranged, the staple cartridge is arranged in a staple cartridge frame, the staple cartridge frame is pivotally connected with a closing handle, the staple cartridge frame is close to the A limit protrusion is provided at the closing handle, and a buffer sleeve is provided outside the limit protrusion.
优选的，所述闭合把手侧边对应位置处开设有弧形槽，所述弧形槽与所述限位凸起的外廓相配，所述限位凸起外部的缓冲套与所述弧形槽面接触。Preferably, an arc-shaped groove is provided at a corresponding position on the side of the closing handle, the arc-shaped groove matches the outer contour of the limiting protrusion, and the buffer sleeve outside the limiting protrusion matches the arc-shaped Groove contact.
优选的，所述缓冲套为橡胶套。Preferably, the buffer sleeve is a rubber sleeve.
优选的，所述橡胶套与限位凸起之间为紧配合或粘接。Preferably, the rubber sleeve and the limiting protrusion are tightly fitted or bonded.
优选的，所述缓冲套为包覆在所述限位凸起上的医用胶层。Preferably, the buffer sleeve is a medical adhesive layer coated on the limiting protrusion.
本发明的有益效果主要体现在：通过在闭合把手侧边对应限位凸起的位置处开设弧形槽，该弧形槽与限位凸起面接触，并且在限位凸起的外部增设缓冲套，提高了直线型缝切器的使用舒适度。The beneficial effect of the present invention is mainly reflected in: by opening an arc-shaped groove at the position corresponding to the limit protrusion on the side of the closed handle, the arc-shaped groove is in contact with the surface of the limit protrusion, and a buffer is added outside the limit protrusion The sleeve improves the comfort of the linear seam cutter.

具体实施方式Detailed ways
如图1和图2所示，本发明揭示的一种直线型缝切器，包括相对设置的钉砧1和钉仓2，所述钉砧1外表面设置有钉砧外壳3，所述钉仓2设于一钉仓架4内，所述钉仓架4与闭合把手5枢轴连接。所述钉仓架4上近所述闭合把手5处设有限位凸起6，与所述限位凸起6的外廓配合在所述闭合把手5侧边对应位置处开设有弧形槽51，所述限位凸起6与所述弧形槽51面接触，提高了器械使用的舒适度。As shown in Fig. 1 and Fig. 2, a linear seam cutter disclosed by the present invention includes an anvil 1 and a staple bin 2 which are arranged oppositely, an anvil shell 3 is arranged on the outer surface of the anvil 1, and an anvil shell 3 is arranged on the anvil 1. The magazine 2 is arranged in a staple magazine frame 4 which is pivotally connected with the closing handle 5 . A limit protrusion 6 is provided on the staple cartridge rack 4 close to the closing handle 5, and an arc-shaped groove 51 is opened at a corresponding position on the side of the closing handle 5 in cooperation with the outline of the limit protrusion 6. , the limiting protrusion 6 is in surface contact with the arc-shaped groove 51, which improves the comfort of using the instrument.
在本发明的优选实施例中，在限位凸起的外部还增设一个缓冲套，该缓冲套可以是橡胶套7，橡胶套7与限位凸起6之间的连接可以是粘结、注塑或者螺旋连接等方式，当然也可以是最简单的紧配合。所述缓冲套还可以为包覆在所述限位凸起上的医用胶层，可以起到减轻限位凸起与闭合把手接触时的冲击即可，因此，由于缓冲套的存在，使得限位凸起与闭合把手之间的配合为柔性配合，使得直线型缝切器的使用手感更佳。In a preferred embodiment of the present invention, a buffer sleeve is added outside the position-limiting protrusion, which can be a rubber sleeve 7, and the connection between the rubber sleeve 7 and the position-limiting protrusion 6 can be bonding, injection molding Or screw connection, etc., of course, can also be the simplest tight fit. The buffer sleeve can also be a medical adhesive layer coated on the limit protrusion, which can reduce the impact when the position limit protrusion contacts the closing handle. Therefore, due to the existence of the buffer sleeve, the limit The cooperation between the position protrusion and the closed handle is a flexible cooperation, which makes the linear seam cutter feel better in use.
本发明尚有多种实施方式，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。There are still many implementations in the present invention, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present invention.
