Embodiment Construction

[0114] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0115] Herein, "rear end" refers to the end close to the operator, and "front end" refers to the end away from the operator. The directions of "up, down, top, bottom, left, right" are indicated in the corresponding drawings (such as figure 2 ) to describe the position shown, not to limit the direction of each component when the stapler is actually used, the positions of "up, down, top, bottom, left, right" correspond to the following figure 2 direction shown. For the convenience of description, the front-b...

Abstract

The invention discloses an anastomat with an effect of implementing pre-pressing and a control method of thereof. A propelling rack is driven through a push block by operating a handle, and a swing block is driven to rotate, a pre-pressing sleeve is driven to move toward the far end of the anastomat by utilizing a swing block connecting rod, a swing block push rod and other a plurality of intermediate driving parts, and the jaw of an actuator is closed; and the propelling rack is used for driving the intermediate driving parts of the pre-pressing sleeve to move toward the near end of the anastomat through a percussion rod, and the jaw is opened. According to the anastomat, percussion operations of pre-pressing and cutting anastomosis can be carried out by means of the handle, and the structure of the pre-pressing assembly of the anastomat is simplified.

Description

technical field [0001] The invention relates to a stapler, in particular to a stapler capable of implementing preloading and a control method thereof. Background technique [0002] A stapler is a device used in medicine to replace manual suturing. The stapler is generally equipped with structures such as an actuator and a cutting knife. During the operation, the tissue to be anastomosed is clamped and occluded in the jaws of the actuator (including the staple cartridge assembly and the staple felt assembly), and the handle of the instrument gun is pressed to drive the cutting knife to cut off the tissue. The staples are pushed out and shaped to staple the tissue. [0003] Existing staplers are basically divided into two categories. Such as Figure 29 The shown stapler has an independent preloading mechanism, which can first close the jaws of the actuator to clamp the tissue, and then perform the operation of cutting and anastomosis. However, the structural design of this ...
