End angle adjustable anastomat for intracavity cutting

Abstract

The invention discloses an end angle adjustable anastomat for intracavitary cutting, and belongs to the field of medical instruments, the anastomat comprises a handle body, the left side of the handle body is rotatably connected with a rotating tube, the left side of the rotating tube is hinged with a connecting tube, and the left side of the connecting tube is in threaded connection with a nail abutting base; the nail abutting baseis hinged with a nail bin base. According to the scheme, by arranging the limiting plate, the rotating handle can be effectively fixed, the situation that the rotating handle rotates when not used, and tissue of a patient is scratched easily is avoided, in cooperation with use of a third push rod, medical staff only need to press the third push rod, the limiting plate and the rotating handle can be separated, and adjustment by the medical staff is facilitated. When the medical staff loosens the third push rod, the third spring can drive the limiting plate to reset quickly, the situation that the nail abutting base and the nail bin base shake in the operation process, the operation risk is increased is avoided, and thus the good limiting effect is achieved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a stapler for intracavity cutting whose end angle can be adjusted. Background technique [0002] Stapler is a device used in medicine to replace manual suturing. The main working principle is to use titanium nails to separate or anastomose tissues. It is similar to a stapler. According to different scopes of application, it can be mainly divided into skin staplers, digestive tract ( Esophagus, gastrointestinal, etc.) circular stapler, rectal stapler, circular hemorrhoid stapler, circumcision stapler, blood vessel stapler, hernia stapler, lung cutting stapler, etc. [0003] In order to meet the needs of medical staff, the existing endocavity cutting staplers usually design the end of the endocavity cutting stapler to be rotatable. The stapler rotates again to cut through the patient's tissue, which not only increases the work intensity of the medical staff, but also increases t...

[0003] In order to meet the needs of medical staff, the existing endocavity cutting staplers usually design the end of the endocavity cutting stapler to be rotatable. The stapler rotates again to cut through the patient's tissue, which not only increases the work intensity of the medical staff, but also increases the risk of surgery, which has great limitations
