Abstract

A buck-boost voltage stabilizing circuit for an electric anastomat disclosed by the present invention is composed of an SEPIC circuit, a sampling circuit and an enabling circuit, wherein a sampling DC-DC boost chip is arranged on the SEPIC circuit, the enabling circuit is arranged at the input voltage end of the SEPIC circuit, the sampling circuit is arranged at the output voltage end of the SEPICcircuit. The sampling DC-DC boost chip outputs a variable duty ratio control signal according to the change of the input voltage of the SEPIC circuit and the output voltage of the SEPIC circuit, andthe variable duty ratio control signal is output from a switch output pin of the sampling DC-DC boost chip so as to drive the SEPIC circuit; the SEPIC circuit adjusts the output voltage in real time according to the control signal of the DC-DC boost chip; the input voltage end of the SEPIC circuit is provided with an isolation diode. The buck-boost voltage stabilizing circuit stabilizes power supply and provides a stable power supply for the control circuit.

Description

technical field [0001] The invention relates to the technical field of voltage stabilizing circuits, in particular to a buck-boosting voltage stabilizing circuit for an electric stapler. Background technique [0002] During the working process of the electric stapler, because the motor operation requires a huge current, the power supply fluctuates greatly. The maximum power supply can drop below 4V, so that the post-stage voltage regulator circuit stops working, which seriously affects the stable operation of the control circuit. [0003] As we all know, stapler is a device used in medicine to replace manual suturing. It uses titanium nails to cut or anastomose tissues, similar to a stapler. According to different scopes of application, it can be mainly divided into skin staplers and digestive tract circular anastomosis. Stapler, rectal stapler, circular hemorrhoid stapler, circumcision stapler, blood vessel stapler, hernia stapler, lung cutting stapler, etc. If the power ...
