Problems solved by technology

The operation action of the electric stapler includes the closing and firing of the staple cartridge assembly, the swinging movement of the staple cartridge assembly and the rotation of the staple cartridge assembly around its own axis. The power sources of multiple motors control each action separately, and the corresponding power transmission system needs to be installed in the stapler, resulting in high cost, heavy weight and complex structure of the electric stapler

Embodiment Construction

[0024] figure 1 is a schematic diagram of an electric surgical instrument according to a first embodiment of the present invention. The electric stapler 10 includes: a staple cartridge assembly 100 and a hand-held assembly 200 . The staple cartridge assembly 100 can be an existing swingable head staple cartridge assembly, which includes an anvil, a staple cartridge, a cutting knife assembly and a transmission assembly. The transmission assembly is driven by external force to realize swinging, opening, closing and firing of the staple cartridge. figure 2 is a schematic diagram of the movement of the staple cartridge assembly. It shows the movement forms that the staple cartridge assembly 100 can realize under the driving of the hand-held assembly 200 , including swinging head movement and pivoting around its own axis.

Abstract

The invention relates to a handheld assembly of an electric surgical instrument and the electric surgical instrument. The handheld assembly of the electric surgical instrument comprises a power assembly, a driving assembly, a switching assembly, a first power output assembly, a second power output assembly, a control circuit and a casing part, wherein the switching assembly comprises a shaft, a first gear, a second motor, a transmission rod and a switching meshing part; and the switching meshing part enables the switching assembly to be in a first output mode or a second output mode. The handheld assembly of the electric surgical instrument realizes swing rotation, occlusion and percussion of a screw bin assembly through a first motor with high power. The complexity of the structure of theelectric surgical instrument is reduced and the cost is saved. Meanwhile, the output modes are switched through a second motor with low power, and an insurance structure for preventing mis-percussionis formed by setting an initial driving state.

Description

technical field [0001] The invention relates to a medical surgical instrument, in particular to a hand-held assembly of an electric surgical instrument and an electric surgical instrument using the hand-held assembly. Background technique [0002] In surgery, staplers are usually used to resect tissues and seal wounds. Staplers include linear cutting staplers, tubular staplers, endoscopic linear cutting staplers, etc. These staplers can be used to resect diseased tissues of the lung, intestine, and stomach while sealing the wound. During the operation, the end effector of the stapler clamps and squeezes the tissue, then cuts the tissue with a cutting knife, and quickly sutures the wound with staples. The use of the stapler shortens the operation time, improves the success rate of the operation, and recovers quickly after the operation. [0003] The currently used stapler mainly has two kinds of manual operation and electric operation. During the operation, the front end ...
