Opening and closing device of laparoscopic purse-string device

Abstract

The invention relates to the field of medical instruments and particularly relates to an opening and closing device of a laparoscopic purse-string device. The opening and closing device comprises a closure device, a first opening and closing mechanism and a second opening and closing mechanism, wherein the closure device comprises a first staple cartridge and a second staple cartridge; the first opening and closing mechanism comprises a handle, a first operation gear set, a first rack and a second opening and closing gear set which are sequentially connected; the first opening and closing gear set is connected with the first staple cartridge; the second opening and closing mechanism comprises a rotary knob, a second operation gear set, a second rack and a second opening and closing gear set which are sequentially connected; and the second operation gear set is connected with the second staple cartridge. Compared with the prior art, the opening and closing device is scientific and reasonable in structure; and two parts of the closure device at a head end can independently rotate and can rotate at the same time, and the rotation angle is relatively large, so that the operation is facilitated, thereby improving the security and success rate of the operation.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an opening and closing device for a laparoscopic purse-string stapler. Background technique [0002] With the rapid development of science and technology, the call for minimally invasive medical treatment is getting stronger and stronger.
