Problems solved by technology

Due to the high nailing force of the linear stapler, the upper and lower nails are inconsistent. In order to solve this problem, the commonly used method is to pre-bend the jaws to ensure the consistency of the upper and lower nails. The design and preparation of linear staplers have put forward high requirements, and in actual use, even if the jaws are pre-bent, there are still problems with nailing

Abstract

The invention relates to a surgical instrument which is used for suturing and cutting tissue. The surgical instrument comprises a gun body and a nail bin component arranged on the gun body, the gun body comprises a closing rod, a triggering rod, a nail anvil support and a nail anvil, the nail bin component is connected with the triggering rod and the closing rod and comprises a bin body, a suturing nail mounted in the bin body, a nail pushing plate for pushing the suturing nail out of the bin body and a cutting component capable of moving relative to the bin body, the cutting component is abutted against the nail pushing plate to enable the suturing nail to move out of the bin body, the triggering rod has a front end face abutted against the cutting component, and the front end face is arc-shaped or conical. The surgical instrument can improve nail forming effect of the suturing nail; after the front end face is arranged to be arc-shaped or conical, the nail anvil support does not needto be pre-bent, so that the surgical instrument is simpler to design and manufacture.

Description

technical field [0001] The present invention relates to a surgical instrument. Background technique [0002] In general surgical treatment, surgical instruments are surgical tools in medical operations, and linear staplers are surgical instruments that are often used to complete the function of tissue cutting and anastomosis. They are used in medicine to replace manual suturing. Its main working principle is to use titanium nails (staples) to separate or anastomose tissues, similar to a stapler. Due to the high nailing force of the linear stapler, the upper and lower nails are inconsistent. In order to solve this problem, the commonly used method is to pre-bend the jaws to ensure the consistency of the upper and lower nails. The design and preparation of linear staplers have put forward high requirements, and, in actual use, even if the jaws are pre-bent, there is still a problem of staple formation. Contents of the invention [0003] The object of the present invention ...
