Problems solved by technology

Although it solves the problem of inner diameter conversion, the end of the puncture cannula is bulky due to the use of the paddle-type conversion method, which is not conducive to the operation
Moreover, after the paddle is toggled many times, the paddle-type converter is prone to problems such as damage, jamming, and inaccurate alignment, which will affect the operation.
In addition, the existing inner diameter converter is generally fixed on the puncture cannula and cannot be disassembled. Once the surgical device is stuck, the entire puncture cannula has to be pulled out

Abstract

The invention discloses a manufacturing method for a diameter-variable abdomen puncture outfit. The manufacturing method is characterized by comprising following steps: (1) arranging a cannula apparatus provided with a rotation diameter-variable device comprising a driver plate, a slide rail plate and slide blocks, wherein the driver plate is provided with more than two arc grooves, the slide rail plate is provided with more than two slide rails, more than two slide blocks are correspondingly arranged on the slide rails of the slide rail plate, each slide block is provided with a guide pin matching the corresponding arc groove of the driver plate, and the arc grooves in the driver plate drive the slide blocks to inwardly or outwardly move along the slide rails of the slide rail plate when the driver plate rotates, so that the inner diameter can increased or decreased; (2) arranging a puncture needle apparatus; and (3) inserting the puncture needle apparatus into the cannula apparatus for matching, thereby forming the diameter-variable abdomen puncture outfit. The invention also discloses the diameter-variable abdomen puncture outfit manufactured by the method mentioned above.

Description

technical field [0001] The invention relates to the technology in the field of medical devices, in particular to a method for manufacturing a variable-diameter abdominal puncture device and the variable-diameter abdominal puncture device. Background technique [0002] With the development of television technology and camera technology, minimally invasive surgical methods represented by laparoscopic surgery have developed rapidly in recent years. Minimally invasive treatment technology is gradually recognized by doctors because of its small operation and small trauma. It is an inevitable trend in the development of future surgical methods. At present, in gynecology, general surgery and other operations involving the abdominal cavity, it is gradually changing from open surgery to minimally invasive surgery in the cavity. More and more doctors have been trained in laparoscopic technology, and their surgical operations are becoming more and more proficient, which has played an ...
