Problems solved by technology

In minimally invasive surgery, the controller of the instrument that is not under the control of the doctor may be displaced due to accidental touch during the operation. Controlled displacement; because the actuator at the distal end of the instrument is very close to the tissues and organs in the surgical target area, uncontrolled displacement of the actuator may damage nearby tissues and organs
When the instrument room is not operated temporarily, some doctors will withdraw the instrument from the body to avoid risks; in some cases, the instrument will be temporarily held by another doctor; sometimes, the doctor just releases the instrument and puts the distal end of the instrument Pressing against tissue or in gaps in tissue that either prolongs the procedure or risks damaging tissues and organs

Abstract

The invention provides surgery equipment with a one-hand operated safety device and an operation method thereof; the surgery equipment comprises a performer, an intermediate connector and a controller connected in sequence; the performer comprises a stapling cartridge assembly, a staple anvil assembly and a driving assembly; the controller comprises a percussion trigger mechanism and a percussion safety mechanism. A stapler can be operated by one hand so as to open the percussion safety mechanism while ensuring operation safety, thus reducing operation process risks, and shortening operation time.

Description

technical field [0001] The present invention relates to a surgical instrument, in particular to a surgical stapler, in particular to an improved surgical instrument safety device and an operating method thereof, which can realize the convenient and safe opening safety function by operating the instrument with one hand. Background technique [0002] The working principle of the surgical stapler is to clamp the tissue by closing two corresponding jaws (commonly known as the nail anvil assembly and the staple cartridge assembly), and then push the metal staples in the staple cartridge into shape to suture the tissue together. In some staplers, a cutting knife is also installed to cut off the stitched tissue. [0003] The stapler with the above functions includes an actuator, an intermediate connecting body and a controller. The actuator is composed of an anvil assembly, a staple cartridge assembly and a driving assembly. The nail anvil assembly includes a nail forming surfac...
