Problems solved by technology

In the case of minimally invasive surgery, the diameter of the anastomotic stoma is relatively small, so the stapler in the prior art is likely to cause the staples of the stapler to fall off when it is taken out, and the anastomotic stoma will burst

Embodiment Construction

[0032] The following describes the embodiments according to the present invention in detail with reference to the accompanying drawings. It should be pointed out that these drawings are only schematic and are not necessarily drawn to scale, and do not constitute a limitation on the protection scope of the present invention.

[0033] figure 1 The structure diagram of the stapler according to the present invention is shown. Such as figure 1 As shown, the stapler includes: a staple seat assembly 1, a staple cartridge assembly 2, a connecting assembly 3, a firing assembly 4, a transmission assembly 5, a movable handle 6, a fixed handle 7 and an adjustment assembly 8. For convenience, in the following description, the side close to the operator is called the proximal end (that is, the side where the adjustment component 8 is located), and the side far away from the operator is called the distal end (that is, the nail seat assembly 1 On the side).

[0034] In this stapler, the nail sea...

Abstract

The invention provides a side-falling nail-supporting seat component and an anastomat using the side-falling nail-supporting seat components. The nail seat components (1) comprises a nail-supporting seat (9), a stopper (10), and a connecting part for flexible connection; when the anastomat is operated, the stopper (10) is clamped at the joint of the nail-supporting seat (9) and the anastomat so as to keep the vertical state of the nail-supporting seat (9); after the operation of the anastomat is completed, the stopper (10) moves away from the joint of the nail-supporting seat component (1) and the anastomat, so that the nail-supporting seat component (1) can fall obliquely. The invention is also provided with an anastomat using the side-falling nail-supporting seat component. The side-falling nail-supporting seat component and the anastomat of the invention have the advantages of simple structure and convenient operation, can avoid the damage on tissues at anastomosis parts when taking out the side-falling nail-supporting seat component and the anastomat; and in the processes of production and inspection, a scalpel gasket can be replaced conveniently so as to carry out repeated tests.

Description

Technical field [0001] The present invention relates to medical equipment, and more specifically, to a side-foldable nail abutment base assembly and an stapler using the nail abutment base assembly. Background technique [0002] Stapler is a medical device that replaces traditional artificial sutures in surgical operations. Among them, tubular staplers are widely used in human digestive tract operations, such as end-to-side anastomosis operations such as the esophagus, stomach, duodenum, and small intestine in the digestive tract. Especially when the operated interface is relatively short or the line of sight is unclear, it is even more necessary to use a stapler to realize the suture of the wound. In surgical operations such as the reconstruction of the digestive tract, the use of medical staplers to assist the incision suture has the advantages of simple operation, rapid suture, and basically no side effects and complications. [0003] High-quality anastomosis technology is the...
