Abstract

The invention discloses a releasable choledochoscope calculus-extracting netting basket which comprises a handle, a push rod, a netting basket body and an outer sleeve with the top end sealed. During extracting of calculus, the calculus is clamped between a first netting basket wire and a second netting basket wire, gas is enabled to enter a netting bag to plump the same, and the outer sleeve is pulled to hold the calculus in the netting bag to move out of a body, so that the netting basket is simple in extracting process, high in accuracy, low in requirements on skills of an operator and high in suitability; when encountering a blockage, a sealing valve on a gas outlet is opened, the gas in the netting bag is discharged to release the calculus, an inner core rod is rotated relative to an outer-layer rod so as to adjust a distance between the first netting basket wire and the second netting basket wire, and the outer sleeve is pulled to take the calculus-extracting netting basket out to avoid incarceration, so that the problem of simultaneous diastasis or partial diastasis of the calculus and a metal head in the prior art is avoided, the netting basket can be taken out smoothly, other complications like surgery and massive haemorrhage are avoided, and surgical risk is lowered.

Description

technical field [0001] The invention belongs to the technical field of medical products, and more specifically relates to a releasable choledochoscope stone extraction net basket. Background technique [0002] The usual methods for removing stones are as follows: 1. Use metal hard stone removing forceps to explore and remove stones along the direction of the bile duct. 2. Flush to remove stones, this method is milder than the former, but the reflux is obvious during flushing, so the flushing pressure is low, and it cannot effectively remove large or less mobile stones. Poor, and imaging is not possible to understand the patency of the lower segment of the bile duct; 3. Use the special stone extraction basket for choledochoscope to explore and extract stones. This method can effectively extract stones and is safe and easy to learn. It is suitable for laparotomy and laparoscopic surgery. [0003] However, during the entire clinical process of stone extraction with the basket,...
