Surgical instrument with safety device and one-handed operation

Abstract

The invention provides a surgical instrument with a safety device capable of being operated with single hand. The surgical instrument with the safety device capable of being operated with the single hand comprises an actuator, an intermediate connecting body and a controller. The actuator, the intermediate connecting body and the controller are connected in sequence, the actuator comprises a nail bin assembly, a nail anvil assembly and a driving assembly, and the controller comprises a triggering trigger mechanism and a triggering safety mechanism. According to the surgical instrument with the safety device capable of being operated with the single hand, under the premise that safety is not lowered, an anastomat can be operated with the single hand to open the triggering safety mechanism, risks in an operation process can be lowered, and operation time can be shortened.

Description

technical field [0001] The present invention relates to a surgical instrument, in particular to a surgical stapler, in particular to an improved safety device for a surgical instrument, which can be operated with one hand to achieve a convenient and safe opening safety function. Background technique [0002] The working principle of the surgical stapler is to clamp the tissue by closing the two corresponding jaws (commonly known as the 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 surface, and the nail forming surface includes a...

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
