Problems solved by technology

However, the present surgical cutter and stapler cannot satisfy all surgical operations. For example, when performing tumor resection on the edge of the lung, a linear cutter and stapler is generally used to perform two roughly vertical or angled cross cutting and suturing to form a Wedge-shaped incision, but this kind of operation is not only slightly complicated in the operation procedure; more importantly, the intersection of the two cuts and sutures is easy to cause anastomotic leakage, which is a frequent area of ​​postoperative sequelae and complications. The body will also have some influence

Embodiment Construction

[0026] The invention discloses a surgical cutting stapler, such as figure 1 As shown, it includes a staple cartridge 1, a nail pusher seat 2 and an anvil 3, and a first clip seat 41 and a second clip seat 42 hinged to each other, and the described nail pusher seat 2 is fixed on the first clip seat 41. At the front end, the anvil 3 is fixed on the front end of the second clamping seat 42 , and the rear ends of the first clamping seat 41 and the second clamping seat 42 are both clamping seat handles 43 . As in the prior art, the staple cartridge 1 and the staple anvil 3 are arranged opposite to each other to form a suturing area of ​​the instrument, and the tissue to be sewn is placed between the two.

[0027] In the present invention, combining Figure 2 to Figure 4 As shown, the outer contours of the staple cartridge 1, the staple pusher seat 2 and the staple anvil 3 are consistent and are all arranged in an arc shape. The surface 14 of the staple cartridge 1 opposite to the...

Abstract

The invention provides a surgical incision stapler, comprising a nail bin and a nail anvil which are arranged in an arc shape, wherein the nail bin is provided with at least one row of nail bin holes and a knife slot, and a set of push plates, a cutter knife and nails are movably arranged in the nail bin, and the nail anvil is correspondingly provided with at least one row of nail shaping slots and a knife slot. The surgical incision stapler is further composed of a push plate stand, a first holder and a second holder which are mutually articulated, wherein the push plates and the cutter knife are arranged on the push plate stand, the push plate stand is fixed at the front end of the first holder, and the nail anvil is fixed at the front end of the second holder. The surgical incision stapler has the beneficial effects of small and smart structure, simple use and low cost, the most important is the arc-shaped incision suturing track, which can be used for once incision and suturing of tumor tissues at the edges of organs, and is worthy of wide application.

Description

technical field [0001] The invention relates to a novel surgical cutting and stapler, which belongs to the field of medical instruments. Background technique [0002] Surgical cutting staplers are widely used in surgical operations for wound closure, internal tissue suturing and cutting. Typical surgical cutters and staplers include circular tubular cutters and staplers disclosed in US Pat. No. 5,275,322, or linear cutters and staplers disclosed in US Pat. No. 5,065,929. The instrument generally has two functions of suturing and cutting. While suturing the wound, excess tissue is removed. However, the present surgical cutter and stapler cannot satisfy all surgical operations. For example, when performing tumor resection on the edge of the lung, a linear cutter and stapler is generally used to perform two roughly vertical or angled cross cutting and suturing to form a Wedge-shaped incision, but this kind of operation is not only slightly complicated in the operation procedu...
