A new type of stone removal device used in clinical hepatobiliary surgery

Abstract

The invention discloses a new type of stone removal device for clinical hepatobiliary surgery, which includes a box body, a second motor is arranged on the inner rear side of the box body, the front output shaft of the second motor is connected to a gear, and an outer tube is arranged on the left front side of the box body. The right end of the outer tube communicates with the through hole on the left front side of the box body, the inner lower side of the outer tube is provided with a chute, the inner part of the outer tube is provided with an inner rod, and the lower side of the inner rod is provided with a slider, which slides with the chute To connect, the right end of the inner rod passes through the right end of the outer pipe and stretches into the casing, and the right end of the inner rod is connected with the left end of the rack. This new type of stone removal device for hepatobiliary surgery is easy to operate, so that the whole device remains stable when medical workers use it, so that the stone can be more accurately aligned with the stone during stone removal, and the wound can be properly opened to facilitate insertion into the wound for stone removal. , Stone extraction can also be performed when the stones are stuck together, blood can be leaked out, and it is convenient to connect medical equipment such as lighting lamps, which is beneficial to the stone extraction work.
