Problems solved by technology

[0004] In order to solve the above technical problems, the present invention provides a stone extraction basket suitable for the urinary system to solve the problem that the existing stone extraction mesh basket is not stable enough during stone extraction, and cannot take out smaller stone fragments, and cannot perform well. Controlling the net basket leads to the phenomenon of too fast movement, which is not conducive to the removal of stones

Abstract

The invention provides a calculus fetching mesh basket suitable for the urinary system, and specifically comprises a device body, wherein a connecting device is mounted on the outer side of the device body; a calculus fetching device is slidably arranged on the outer side of the device body, and an auxiliary mechanism is fixedly arranged on the front side of the device body; an adjusting mechanism is fixedly arranged at the bottom of the connecting device; a fixing device is fixedly arranged at the bottom of the adjusting mechanism; a mesh basket device is slidably arranged in the auxiliary mechanism; and an adsorption mechanism is fixedly arranged in the mesh basket device. According to the calculus fetching mesh basket suitable for the urinary system, an adjusting gear is matched with a toothed plate to realize the purpose that a transverse column drives connecting frames to move front and back, the effect of effectively controlling the moving speed of a catheter is achieved, and the effect of preventing a mesh basket piece from moving too fast is achieved.

Description

technical field [0001] The invention belongs to the technical field of the urinary system, and more specifically relates to a stone extraction net basket suitable for the urinary system. Background technique [0002] The stone extraction basket is widely used in the treatment of stones in different surgical fields such as urology and biliary tract. The stone extraction basket is also a surgical instrument often used in hard mirror gallstone removal surgery. The stone extraction basket is often used in conjunction with the endoscope. , used to remove stones or foreign bodies in the digestive tract, urinary tract and respiratory tract; most ureteral stones originate from the kidney, including kidney stones or stone fragments falling after external shock waves. Primary ureteral stones are rare because urinary salt crystals are more easily excreted into the bladder with urine. [0003] Based on the findings of the prior art, most of the existing stone retrieval net baskets are ...
