Abstract

The invention discloses a reusable handle of a laparoscope scalpel in the technical field of surgical instruments. The handle comprises a closed housing, a transmission mechanism, a trigger and an output rotating shaft, wherein the transmission mechanism is arranged in an inner space of the closed housing; the trigger is movably connected with an outer wall of the closed housing; and magnetic pieces are arranged at an input part of the transmission mechanism, on the trigger, at an output part of the transmission mechanism and on the output rotating shaft respectively, so that an acting force on the trigger is transferred to the output rotating shaft in a non-contact manner. The handle adopts the totally-closed housing, so that blood and other dirt are prevented from entering the interior of the handle during a surgery, and the handle can be used continuously and safely after disinfected integrally.

Description

technical field [0001] The invention relates to a device in the technical field of surgical instruments, in particular to a multiple-use laparoscopic scalpel handle. Background technique [0002] Existing laparoscopic scalpels generally use disposable handles, which are discarded after use. Although cross-infection is avoided, the operation costs are expensive and the financial burden on patients is heavy. The disposable handle is an open cavity in structure, and there are through holes on the handle, and the internal shaft and gears are transmitted through the through holes for contact torque transmission. In this way, blood and dirt have the opportunity to enter the inside of the handle during the operation, causing pollution and affecting the operation of the handle. Efficiency of internal transfer agencies. [0003] At present, the handle can be used many times, and it has been improved on the basis of the open structure. The method is to set a sealing ring at the posit...
