Anastomat capable of reducing abrasion of nail anvil frame

Abstract

The invention discloses an anastomat capable of reducing abrasion of a nail anvil frame, and belongs to the technical field of medical instruments.The anastomat is characterized by comprising an anastomat body, the right side of the anastomat body is rotationally connected with a rear handle, the left side of the anastomat body is fixedly connected with an assembly shell, and a nail pushing part is arranged on the inner wall of the assembly shell; the left side of the assembly shell is fixedly connected with an anastomosis component tube, the inner wall of the anastomosis component tube is provided with an annular nail bin, the inner wall of the nail bin is provided with anastomosis nails, and the inner wall of the anastomosis component tube is provided with a movable groove. According to the anastomat disclosed by the invention, by arranging the driving sleeve, when a medical worker enables the anastomat body to work and perform anastomosis, the driving sleeve can move towards the left side, the screw rod can rotate through the notch matched with the screw rod, the driven rod fixedly connected with the screw rod can synchronously rotate, and when the driven rod rotates, the driven rod can be located in the positioning rod to rotate through the rotating block matched with the rotating groove.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a stapler capable of reducing wear of an anvil frame. Background technique [0002] The world's first stapler was used for gastrointestinal anastomosis for nearly a century. It was not until 1978 that the tubular stapler was widely used in gastrointestinal surgery. The stapler is also called a cutting stapler. It is generally divided into one-time or multiple-use staplers. It is a device used in medicine to replace traditional manual suturing. Due to the development of modern technology and the improvement of production technology, the clinically used staplers are reliable in quality and easy to use. Tight, tight and suitable, especially its fast suturing, easy operation, few side effects and surgical complications, etc., and sometimes enables tumor resection that was unresectable in the past, and is very popular and respected by clinical surgeons at home and abroad. ...

AI Technical Summary

Problems solved by technology

[0003] After long-term use of the anvil part of the existing stapler, the contact surface between it and the staple cartridge is easily worn due to repeated contact with the staples, and there is no related solution at present. When the wound is anastomosed, it is necessary to remove the whole body from the patient's body. Due to the special shape of the stapler, it will scratch the anastomosis when it is taken out, which may cause secondary damage to the patient. Stapler with frame wear, to solve the problems raised in the above-mentioned background technology
