AI Technical Summary

⚠Technical Problem

Existing myoma drills are inefficient in laparoscopic surgery, requiring frequent adjustments to the operating position, making accurate positioning difficult, and the fragmented tumor tissue is prone to scattering, posing a risk of dissemination.

⚗Method used

A laparoscopic integrated vacuum-sealed rotary myoma drilling system was designed, including a sheath body, a cannula cutting assembly, an external isolation assembly, a suction tube, a control unit, and a handle. The cannula cutting assembly and hook assembly enable rapid positioning and rotary cutting of tissue, the external isolation assembly provides wrapping and isolation, and the suction tube collects tissue, ensuring a clear and safe surgical field.

🎯Benefits of technology

It achieves efficient and precise fibroid removal, avoids tumor tissue fragmentation, protects surrounding tissues, and ensures that tissue fragments are collected intact for postoperative analysis.

Abstract

The present application relates to laparoscopic myoma in situ rotary cutting system, specifically to laparoscopic integrated vacuum closed rotary cutting myoma drill system, including sheath body, sleeve cutter assembly, outer extension isolation assembly, suction tube, control part and handle part, the center of the sheath body is installed with sleeve cutter assembly, the sleeve cutter assembly includes outer tube body and rotary tube body, the outer tube body is attached to the inner tube body and rotates, the rear end of the outer tube body is provided with a fixed skirt plate fixedly connected with the inner wall of the sheath body, a driving cavity is arranged between the sheath body and the outer tube body, the driving cavity is a closed tube body, a driving air tube is arranged at the rear of the driving cavity, a piston body is slidably arranged in the driving cavity, and the front part of the piston body is fixedly connected with the outer extension isolation assembly. The sleeve cutter assembly and the hook pulling assembly can quickly position and lock the myoma tissue to be cut, and realize self-drag rotary cutting through the back-pulling mode.
