AI Technical Summary
Technical Problem
Existing intrauterine tissue biopsy devices use a sliding helical drive to move the inner tube, which has problems such as low transmission efficiency, difficulty in starting, and easy wear and heat generation.
Method used
A gear transmission mechanism is used to connect the piston and fasteners together. The gear transmission mechanism drives the inner tube to perform linear and rotary motion. The gear meshing transmits motion and power, and the inner tube performs both linear and rotary motion simultaneously.
Benefits of technology
It improves transmission efficiency, has a large inner tube rotation angle and high rotation speed, reduces friction and wear, ensures structural stability and reliability, reduces production costs and improves the safety of biopsy.
