Problems solved by technology

[0003] Gastroenterology lithographs need to use the ultrasonic probe on the stone mesh blue for stone crushing, and then use the stone mesh blue to remove the large crushed stones. Because the overall structure of the ultrasonic probe is small, when taking stones with the stone mesh blue , the ultrasonic probe is easily deformed due to the extrusion and distortion of the stones, resulting in the breakage of the ultrasonic probe, which cannot achieve ultrasonic lithotripsy, and the broken probe will fall off from the interval of the stone removal net and remain in the patient's body, making it difficult to remove

Abstract

The invention relates to a stone extractor for digestive department, which structurally comprises a stone extracting block, a telescopic rod, a connector, a machine body and a telescopic driving cavity, the side, provided with the stone extracting block, of the machine body is fixedly connected with the telescopic driving cavity, the connector is arranged on the side close to the stone extractingblock, the connector is movably clamped with the telescopic driving cavity, and the telescopic rod penetrates through the connector; the connecting head is in clearance fit with the telescopic rod, the stone taking block is located at the top end of the telescopic rod, the stone taking block is movably connected with the telescopic rod through the movable shaft, a wrapping cavity is an arc-shapedwrapping surface, and a ultrasonic probe and other part structures are wrapped in one cavity, so that when a probe body of the ultrasonic probe is twisted and broken, the broken probe falls into the cavity body of the wrapping cavity and does not fall out of the gap of the stone removing net, so that the broken probe is left in the body of a patient and is difficult to take out.

Description

technical field [0001] The invention relates to the field of gastroenterology, in particular to a stone removal tool for gastroenterology. Background technique [0002] Stomach stones are formed by the ingestion of certain animal and plant components, hair or certain minerals that are not digested in the stomach and coagulate into lumps. In the past, traditional Chinese medicine was mostly used to dissolve stones in the treatment of stomach stones. Traditional Chinese medicine treatment takes a long time. Patients undergoing surgery for stone removal are more painful and may have complications. With the development of fiberoptic endoscopic therapy, stone removal tools for gastroenterology have been introduced to remove stones by ultrasonic lithotripsy; [0003] Gastroenterology lithographs need to use the ultrasonic probe on the stone mesh blue for stone crushing, and then use the stone mesh blue to remove the large crushed stones. Because the overall structure of the ultras...
