Electric endoscope anastomat and clutch safety device thereof

Abstract

The invention discloses a clutch safety device of an electric endoscope anastomat. The device comprises a clutch change-over unit, a clutch driving unit and the clutch safety unit; the clutch change-over unit achieves clutch switching of the anastomat between the percussion, close and open states and the left-right transmission state under the action of the clutch driving unit; the clutch safety unit comprises a safety sliding block, a guide rod and a clutch safety circuit board, the safety sliding block can be arranged on the guide rod in a sliding mode, a conductive elastic piece is arrangedon the upper portion of the safety sliding bock, a slideway is arranged on the clutch safety circuit board, the slideway is internally provided with a safety electrical contact end of the anastomat in the percussion, close and open states and a safety electrical contact end of the left-right transmission state, a driving hinge pin is arranged on the lower portion of the safety sliding block, thedriving hinge pin is connected with the clutch driving unit, and under the drive of the clutch driving unit, electrical switch of the anastomat in the two states is achieved. The invention further discloses the electric endoscope anastomat. Accordingly, consistent clutch control over mechanical engagement and electrical control is achieved, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to an electric endoscopic stapler and a clutch safety device thereof. Background technique [0002] With the development of medicine and product research and development, staplers have been widely used in various fields such as gastrointestinal surgery, hepatobiliary surgery, thoracic surgery, urology, obstetrics and gynecology, and have become one of the indispensable tools for doctors. [0003] There are two main types of endoscopic staplers at present: one is a manual endoscopic stapler, which mainly relies on the rack and the firing pusher to realize the advancement of the cutting knife, and the retreat needs to be pulled back manually. The opening and closing of the staple cartridge assembly depends on the knife pin on the cutting knife to push the slope on the abutment seat to realize the opening and closing of the abutment seat. The overall structure is relative...

AI Technical Summary

Problems solved by technology

The overall structure is relatively simple, but the operation is complicated. The stability of the instrument is not good when it is working. Large, it is easy to cause the speed of the cutting knife to cut the tissue from time to time, causing the cut tissue surface to be uneven. final effect

The other is an electric endoscopic stapler, which includes a battery, a circuit control system, a motor, and a transmission system. Since only one motor provides power, it is necessary to realize the closing, opening, firing, and left-right transmission switching functions of the stapler. Equipped with a clutch conversion device, but because the existing clutch conversion device only achieves the switching failure of the mechanical function, its electrical control switch does not correspond to the failure of the mechanical function, and it is prone to misoperation, which is not conducive to the electric endoscopic stapler. stable and reliable work
