Abstract

The invention discloses a stone extraction mesh basket for choledochoscopy, which relates to the technical field of medical auxiliary equipment. The output end, the traction wire is connected to the control handle, the adjusting box is set on the upper surface of the support base, the screw is set in the adjusting box, the nut is set on the surface of the screw, the driving motor 1 is set on the surface of the right side wall of the regulating box, and the driving motor 2 is set on the lower surface of the supporting base. One end of the basket is fed into the human body. The operator controls the control handle to unfold the stone basket. The operator controls the control handle to shrink the stone basket to complete the stone removal. The nut drives the right disinfection box to move up and down in the vertical direction. The main gear drives the upper adjustment box and the disinfection box to rotate through the auxiliary gear, and the pressure pump transports the disinfectant to the nozzle through the infusion pipe to realize the disinfection of the tool, which is more convenient to use and easy to adjust.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a stone extraction basket for choledochoscopy. Background technique [0002] Nephrolithiasis is a common disease of the urinary system. Abnormal metabolism of the body, obstruction of the urinary tract, infection, foreign body and drug use are the common causes of stone formation. With the development of science and technology, flexible ureteroscopic lithotripsy has become one of the methods for the treatment of kidney stones with a diameter of 2 cm or stones in the upper ureter. The holmium laser is used to crush the stone under the flexible endoscope, and then it is taken out as much as possible. [0003] The existing choledochoscope stone extraction basket is inconvenient to install and fix, difficult to adjust, and the tools cannot be disinfected and sterilized in time after the stone extraction is completed. SUMMARY OF THE INVENTION [0004] The purpo...
