Stapler control circuit and electric stapler

Abstract

The invention discloses a stapler control circuit. The circuit comprises a power supply, a firs discharge element, a power supply control switch, a conduction loop, and a control driving loop, the power supply control switch controls the power supply to be connected with a circuit power supply input port, and the power supply control switch controls the first discharge element to perform discharge on the power supply; the conduction loop is connected with the first discharge element in parallel; the control driving loop is connected with the conduction loop in parallel; the control driving circuit includes a direct current motor, a first relay, a second relay and a switching circuit, the switching circuit controls forward rotation, reverse rotation, forward rotation brake stop, reverse brake stop and rotation amount of the direct current motor; all control operations of an endoscopic stapler are completed by one motor; the work efficiency is high, the cost is relatively low, and the burden on patients is reduced; and the battery of the power supply runs out in a limited time, and the original problem of battery environmental pollution is solved .

Description

technical field [0001] The invention relates to the field of stapler control, in particular to a stapler control circuit and an electric stapler. Background technique [0002] Medical staplers have become an indispensable medical device to assist in the process of incision suture. With the development of medical technology, more and more stapler products with different functions have been used clinically. At present, the laparoscopic stapler used in the field of minimally invasive surgery, the blade cuts off the tissue from the middle while firing the staples, and at the same time, three rows of staples on both sides complete the functions of suturing the tissue and stopping bleeding. The operation process of the operation is: the disposable end effector of the endoscopic stapler is assembled on the instrument, the end effector includes the staple cartridge assembly and the anvil, and the connection between the staple cartridge assembly and the anvil can be closed or opened,...

Problems solved by technology

[0008] The purpose of the present invention is to provide a stapler control circuit, which solves the problem of inconvenient, time-consuming and labor-intensive operation of the original manual endoscopic stapler, and the circuit structure is relatively low in cost, and only one motor is used to complete the end effector of the instrument. Closing, opening, sewing, cutting, brake control after closing in place, stop control in place for left rotation and stop control for right rotation in place, brake control after firing in place, return control after firing and return brake stop control, that is, only Use one motor to complete all the control operations of the endoscopic stapler; compared with the existing semi-electric endoscopic stapler, the function is more intelligent and the work efficiency is high; compared with the all-electric intelligent endoscopic stapler, it solves the problem of high cost, and The function is perfect; because it is a one-time use, it reduces the burden on the patient;
