A tubular stapler

Abstract

The invention discloses a tubular stapler, which relates to the technical field of staplers, and includes a staple cartridge assembly. The staple cartridge assembly used for the tubular stapler has a strip-shaped movable contact, and the fixed contact The distance from the midpoint of the rotating rod is smaller than the size of the movable contact, and the length of the movable contact is smaller than the distance between the rotating rod and the nail position, so if the nail position is fully sutured, the movable contact will contact with the staple. At this time, the suturing nail will block its position after the movable contact contacts, so that it cannot continue to rotate, that is, it cannot contact the fixed contact. It is completed and the nail position is accurate, avoiding the situation where the stapler is directly taken out because the operator cannot directly observe the suturing result, reducing the injury to the patient, and improving the safety and reliability of the operation process.

Description

technical field [0001] The invention relates to the technical field of staplers, in particular to a tubular stapler. Background technique [0002] As a modern medical device, the stapler has a long history of use. It can effectively resect and suture the tissue or blood vessels to be resected during the operation. Using the principle similar to the stapler can make the operation more convenient and cost less. Low. [0003] As a type of stapler, the tubular stapler is commonly used in anorectal or similar departments. Its principle is the same as that of most staplers. They all use the principle of a stapler to suture the incision while resecting the tissue. This process is mainly completed by the staple cartridge assembly. Because the staple cartridge assembly is generally located in the body or tissue during resection and suture operations, the operator cannot directly observe the suture from the outside, and due to problems with the operation or the stapler itself, the s...

AI Technical Summary

Problems solved by technology

Because the staple cartridge assembly is generally located in the body or tissue during resection and suture operations, the operator cannot directly observe the suture from the outside, and due to problems with the operation or the stapler itself, the staples at the suture may be sutured with the tissue Insufficient problem, that is, the resected tissue is still in a state of mutual adhesion at this time. If the stapler is taken out directly at this time, it will cause tissue mucous membrane strain or tear at the suture. On the one hand, it causes secondary injury to the operator, and even causes Infection and other problems, on the other hand, will have a certain impact on the operation process

[0004] In order to solve the above problems, the inventor proposed a tubular stapler, which has the advantage of being able to detect and prompt the suturing state, avoiding the situation where the operator cannot directly observe the suturing result and directly taking out the stapler, and reducing the need for Patient injury, improving the safety and reliability of the surgical procedure
