Novel clinical calculus-removing device used for hepatological surgery department

Abstract

The invention discloses a novel clinical calculus-removing device used for the hepatological surgery department. The device comprises a box body. The back side in the interior of the box body is equipped with a second motor. An output shaft at the front end of the second motor is connected with a gear. The left front side of the box body is equipped with an outer pipe. The right end of the outer pipe communicates with a through hole in the left front side of the box body. A sliding groove is arranged in the lower side in the outer pipe. The interior of the outer pipe is equipped with an innerrod, the lower side of which is provided with a sliding block. The sliding block is slidably connected with a sliding groove. The right end of the inner rod penetrates through the right end of the outer pipe to stretch into the box body. The right end of the inner rod is connected with the left end of a rack. Operation is performed easily. When medical staff uses the device, the overall device remains stable. A calculus can be precisely aligned during calculus removal. A wound can be properly expanded so that the wound is conveniently stretched to remove the calculus. The calculus can be removed in case of adhesion. Bloody water can leak out. The device is conveniently in snap joint with a lighting lamp and other medical equipment so that calculus-removing operation is convenient to carryout.
