Executing assembly of cutting anastomat applicable to minimally invasive surgery

Abstract

The invention discloses an executing assembly of a cutting anastomat applicable to minimally invasive surgery. The executing assembly comprises a jaw, a sleeve, an elastic push plate and two joint connecting plates; a nail bin, a nail abutting seat, a nail pushing sheet and a cutting knife are arranged on the jaw; the front end of the sleeve is hinged with the jaw, and a connecting portion is arranged at the rear end of the sleeve; the elastic push plate can axially slide in the sleeve, and the front end of the elastic push plate is connected with the cutting knife; the two joint connecting plates can axially slide in the sleeve and are positioned on the left side and the right side of the elastic push plate, and the front ends of the two joint connecting plates are hinged with the jaw. The executing assembly of the cutting anastomat has the advantages that the sleeve is hinged with the jaw, the jaw can swing left and right under the forward and backward actions of the two joint connecting plates, and accordingly the flexibility of cutting and anastomosis operation can be greatly improved during minimally invasive surgery; the executing assembly comprises the elastic push plate, and the elastic push plate can be bent when the jaw swings left and right, so that nail pushing and cutting power can be continuously transmitted, and the executing assembly is simple and reliable in structure.

Description

technical field [0001] The present invention relates to the field of surgical medical instruments, in particular to an executive component, which can simultaneously perform surgical stapling and cutting after being loaded into a cutting stapler. Background technique [0002] Minimally invasive surgery mainly uses endoscope and various imaging techniques to enable surgeons to perform surgery without causing huge wounds to patients. There are two small holes with a diameter of about 0.5 cm, one of which is put into a micro-camera, which is connected to the TV screen, and the other small holes in the abdominal wall are put into surgical instruments such as scissors and forceps. The operation process is basically the same as laparotomy. Like surgery, the doctor looks at the screen and performs a series of operations such as clamping, anastomosis, and cutting on the diseased tissue. [0003] Minimally invasive surgery is a brand-new treatment method. The steps of minimally invas...

Problems solved by technology

[0006] However, the end effector of this cutting stapler can only rotate around the axis, but cannot swing left and right relative to the axis, which will bring inconvenience to the operation of minimally invasive surgery.
