Anastomat applicable to magnetic surgical department

Abstract

The invention relates to an anastomat applicable to a magnetic surgical department. The anastomat consists of a gun head and a gun body. The gun head comprises a first magnetic ring, a first magnetic shielding case, an outer connecting shell, an annular cutting edge, a second magnetic ring, a second magnetic shielding case and an inner connecting pipe; the gun body comprises a gun body shell, a cutting propelling device and a thread adjusting device. The first magnetic ring covers the first magnetic shielding case; the outer connecting shell sleeves the first magnetic shielding case and can slide relative to the first magnetic shielding case; the annular cutting edge is arranged on the inner side wall of the first magnetic ring and can slide relative to the first magnetic ring; the second magnetic shielding case covers the second magnetic ring, one end of the inner connecting pipe is provided with a clamping jaw, the other end of the inner connecting pipe is provided with a circular pipe, the inner connecting pipe is installed in a groove in the inner wall of the second magnetic ring through the clamping jaw, the circular pipe can be nested in the annular cutting edge, after the gun body shell is connected with the outer connecting shell, the surplus tissue can be cut by utilizing the cutting propelling device to push the annular cutting edge, the inner connecting pipe is pressed to be separated, the distance between the first magnetic ring and the second magnetic ring is adjusted by utilizing the thread adjusting device, and rapidness, safety and reliability in surgical anastomosis with no foreign matter and stitch remaining in an anastomotic stoma can be realized.

Description

technical field

[0001] The invention belongs to the technical field of medical equipment, in particular to a stapler suitable for magnetic surgery. Background technique

[0002] In many surgical procedures (usually referring to operations on humans, but can also include operations on animals), the anastomosis of the cavity structure so that the lumen is continuous is crucial to the operation. The healing quality of the anastomotic stoma is directly related to the success or failure of the operation, and even the life of the patient. Although the improvement of sutures, such as the emergence of prolene, has greatly reduced the occurrence of postoperative complications, manual suture anastomosis has disadvantages such as technical difficulty, high requirements for the operator, time-consuming, and residual foreign bodies at the anastomosis. Nail-type stapler is currently mainly used for intestinal anastomosis, and its application has certain limitations, and metal foreign bod...
