Embodiment Construction

[0026] 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 motor-driven surgery instrument handheld assembly and a motor-driven surgery instrument. The motor-driven surgery instrument handheld assembly comprises a power source assembly, a driving assembly, a switching assembly, a first power output assembly, a second power output assembly, a control circuit and a housing part, wherein the switching assembly comprises an output switching part with a motor; the output switching part can enable the switching assembly to be in a first output mode or a second output mode. According to the motor-driven surgery instrument handheldassembly disclosed by the invention, swing rotating, closing and firing of a nail bin assembly are realized through a first motor, the complex degree of the structure of the motor-driven surgery instrument is reduced, and the cost is saved; and besides, the switching of output modes is realized through a second motor, and an initial driving state can be set, so that an insurance structure for preventing wrongly firing is formed.

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 ...
