Embodiment Construction

[0022] The technical solutions of the present invention will be clearly and completely described below through specific embodiments in conjunction with the accompanying drawings.

[0023] see Figure 1-4 As shown, the present invention provides a one-stage firing mechanism of a cutting stapler, including an elastic control assembly 1, a push assembly 2, a reset assembly, and an anchor release assembly 3. One end of the elastic control assembly 1 is fixed, and the other end is connected to the push Component 2, the push component 1 is connected to the reset component, and the reset component resets the push component 2, and the anchor release component 3 is used to hang on or release the push component 2, and the push component 2 moves toward the elastic control component 1 After the elastic control assembly 1 is compressed, the push assembly 2 is attached to the anchor release assembly 3 , and when the anchor release assembly 3 is released from the push assembly 2 , the elasti...

Abstract

The invention provides a one-stage type triggering mechanism of a cutting anastomat. The one-stage type triggering mechanism of the cutting anastomat comprises an elastic control subassembly, a pushing subassembly, a resetting subassembly and an attaching and releasing subassembly, wherein one end of the elastic control subassembly is fixed; the other end of the elastic control subassembly is connected to the pushing subassembly; the pushing subassembly is connected with an actuating subassembly which actuates cutting actions and the resetting subassembly and resets through the resetting subassembly; and the attaching and releasing subassembly is attached to the pushing subassembly or released from the pushing subassembly. After the pushing subassembly moves towards the elastic control subassembly to compress the elastic control subassembly, the pushing subassembly is attached to the attaching and releasing subassembly; and when the pushing subassembly is released from the attaching and releasing subassembly, the elastic control subassembly pops up the pushing subassembly. The cutting anastomat and the one-stage type triggering mechanism thereof are simple in structure and high in reliability; potential energy is stored through the elastic control subassembly and is released at one step to push the actuating subassembly to perform cutting actions; and cutting can be finished by triggering once, a surgery process is simplified, and surgical risks are reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a one-stage firing mechanism of a cutting stapler and the cutting stapler. Background technique [0002] At present, many endoscopic cutting staplers on the market are mainly imported brand Johnson & Johnson. The firing parts of this product are mainly composed of cutting handle, cutting knife pushing block, return spring, connecting rod latch, and latch return spring. , rack, large gear, pinion, cutting stroke display, ratchet and other more than 30 parts. The triggering method is: use the handle lever to push the cutter to push the block forward. Due to the short resistance arm, it needs continuous cutting to complete the whole cutting process. Pull the handle three times, considering that doctors tend to forget the number of cuts, a cutting stroke display is also designed. The existing cutting stapler has a complex structure and requires high precision parts, which ...
