Endoscope anastomat with locking structure

Abstract

The invention discloses an endoscope anastomat with a locking structure, and the endoscope anastomat comprises an anastomat body, a rotating structure, a transmission pipe sleeve and an anastomosis head; a movable handle is arranged on the lower portion of the left side of the anastomat body, the rotating structure is installed on the left side of the top of the anastomat body, a rotating button is arranged on the top of the rotating structure, and a rotating shaft is arranged in a rotating base shell; a first bevel gear is installed at the bottom of the rotating shaft, the left side of the first bevel gear is meshed with a second bevel gear, the second bevel gear is meshed with a third bevel gear, the right side of the third bevel gear is fixedly connected with a worm, the worm is meshed with a gear behind, the transmission pipe sleeve penetrates through the rotating structure, and the anastomosis head is arranged on the left side of the transmission pipe sleeve. According to the endoscope anastomat with the locking structure, the worm and the gear are arranged, and the spiral angle of the worm is smaller than the friction angle of the contact surface of the gear and the worm, so that the gear cannot drive the worm to move under the counter-acting force of the nail bin, self-locking at any angle is achieved, and the using effect of the endoscope anastomat is improved.

Description

technical field [0001] The invention relates to the technical field of endoscopic staplers, in particular to an endoscopic stapler with a locking structure. Background technique [0002] At present, minimally invasive surgery occupies an important position in surgical operations, and resection of lesions is an important part of surgical operations. The current general method is that the surgical instrument has a long shaft or rod-shaped structure, and the endoscopic With cooperation, the shaft or rod is inserted into the lesion, and the lesion is resected. In the process of minimally invasive surgery, a stapler must be used. As an important instrument in minimally invasive surgery, a laparoscopic stapler is compatible with a trocar and an endoscope. Cooperate with resection of the patient's lesions. [0003] However, when using a laparoscopic stapler, it is often necessary to rotate the main body of the device to adjust the positions of the staple bin and the nail seat, so ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a laparoscopic stapler with a locking structure to solve the above-mentioned problems in the background technology, but when using the laparoscopic stapler, it is often necessary to rotate the main body of the device to adjust the staple cartridge and the nail abutment seat. Position, to better cut the lesion or suture, but the existing endoscopic staplers rarely have the function of rotation and locking, so that the device may have the problem of automatic rotation after installation
