Problems solved by technology

When using a traditional mechanical stapler, in order to avoid the spread of disease, or the occurrence of secondary cutting to cause new injuries, the cutting knife advances along the jaw hook of the stapler to the top to complete the cutting and stapling. To advance to the top to complete this action, the anastomotic components must be replaced. In the existing mechanical staplers, it is impossible to force the operator to disassemble the anastomotic components through technical means. Only manual confirmation can be used to prevent such things from happening. During the operation, the operator In a state of tension, it is inevitable that the above manual error correction measures will make mistakes, forgetting to replace the anastomotic component, and then use the same tool to perform the same operation on another patient's diseased part, so that the tissue in other parts of the patient will be contaminated by the contaminated stapler.

Abstract

The invention discloses a control circuit of an electric stapler that prevents a detachable stapler assembly from being used again. If the anastomotic component moves to the end position, the control circuit disconnects the electrical path between the cathode of the motor and the negative pole of the power supply, unless the electrical path between the cathode of the motor and the negative pole of the power supply can be restored after the anastomotic component is disassembled again, otherwise it cannot pass Toggle the switch to turn the motor forward again.

Description

technical field [0001] The invention relates to the field of control circuits of medical instruments, in particular to a control circuit of an electric stapler that prevents detachable stapling components from being used again. Background technique [0002] The Chinese patent titled "Motor-Driven Surgical Cutting Instrument" and publication number CN101683284A describes a laparoscopic linear cutting and closing device, which is a surgical instrument that can cut excess tissue of a patient and suture the cut wound at the same time. Typically includes an end stapler having a pair of cooperating jaw members. Disposed in the jaw member is a receiving staple cartridge having two transversely spaced rows of staples - one row on each side of the knife channel. The other jaw member defines an anvil having staple forming pockets aligned with the rows of staples in the cartridge. Tissue is first clamped between the opposing jaw structures, and then the cutting knife is pulled along ...
