Multi-functional stone extractor

Abstract

The invention provides a multi-functional stone extractor which comprises an operation handle, a guide pipe and a stone extractor and is characterized in that the multi-functional stone extractor also comprises a plasma stone breaker, a monitoring device and an illuminating device, the plasma stone breaker is connected with the stone extractor in the guide pipe, the monitoring device consists of a camera, a wire, a switch and a socket, and the illuminating device consists of a light source, a wire, a switch and a socket; the guide pipe consists of an outer resin pipe and an inner resin pipe; the switches and the sockets are used for controlling the work of the light source and the camera, and the camera and the light source are connected with the sockets and the switches through the wires penetrating through the outer resin pipe; a moving groove is arranged on a handle rod of the operation handle, and a moving control ring arranged on the handle rod can move forward and back along the moving groove; and the stone extractor consists of a slider, a fixed base and a net connected between the slider and the fixed base, and the net consists of a plurality of thin steel wire ropes uniformly arranged around the plasma stone breaker. The invention overcomes the defects of the traditional stone extraction operation and has the characteristics of flexible movement, simpleness for control, high safety and reliability, good operation effect and the like.

Description

1. Technical field [0001] The invention relates to a surgical instrument for removing stones, in particular to a multifunctional stone removal tool for gallbladder and bile duct. 2. Background technology [0002] At present, in the minimally invasive surgical treatment of gallbladder and bile duct stones, there has been a lack of dedicated gallbladder and bile duct stone removal tools. In the actual operation, clinicians mainly rely on the stone retrieval basket to remove stones, but the stone retrieval mesh basket is easy to slip when taking stones, especially for small stones; when encountering larger stones, the stone retrieval mesh basket cannot be stretched Stone removal, especially when the stone is incarcerated in the gallbladder or bile duct, the stone retrieval basket cannot pass over the stone, which will lead to a long time for stone removal, or even failure. When stone removal using the stone extraction basket fails, traditional laparotomy instruments are used t...
