Articular head and anastomat thereof

Abstract

The invention relates to the technical field of medical appliances and particularly relates to an articular head and an anastomat thereof. The articular head comprises a lever shaft and a swinging lever matched with a stitching mechanism, wherein a swinging mechanism is arranged between the lever shaft and the swinging lever, a control mechanism which is used for controlling the swinging mechanismto drive the swinging lever to offset relative to the lever shaft is arranged between the lever shaft and the swinging lever, the swinging mechanism comprises a spherical head arranged on the swinging lever, a groove is formed in the lever shaft, the spherical head is arranged in the groove, and a surface of contact between the spherical head and the groove is a spherical surface. When the articular head and the anastomat thereof, disclosed by the invention, are in use, the spherical head is matched with the groove, the swinging lever can swing on the lever shaft, and thus, the adaptability of the anastomat is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a joint head and a stapler thereof. Background technique [0002] Various surgical linear cutting staplers are used to replace the manual anastomosis operation with needles and threads in surgery, and are being widely used in the end-to-end, end-to-side and side-to-side of organs and tissues such as human digestive tract organs, respiratory tract organs, and urogenital organs. Anastomosis and other operations, such as forming organ channels and closing incisions, are especially suitable for anastomosis of organs and tissues that are difficult to expose and operate, which can reduce operation time and improve operation quality. Compared with traditional manual suturing, instrumental suturing has the following advantages: 1. Simple and convenient operation, saving operation time; 2. One-time use, avoiding cross infection; Moderate, 4. It has few side effects and effect...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problem that the existing stapler includes a rod shaft arranged on the firing handle, and one end of the rod shaft is a suture mechanism, and the suture mechanism cannot be deflected relative to the rod shaft, so that the stapler The operation at a certain angle of deflection cannot be realized. Since the patient's surgical position is not fixed, the surgical position requires that the stapler shaft deflect relative to the suture mechanism, which reduces the applicability of the stapler. Now, a joint head and its Stapler
