Medical laparoscope exhaust adjustable foot switch controller

Abstract

The invention discloses a foot switch controller of n exhaust adjustable type for a medical laparoscope. The controller comprises a control unit, a power supply unit, a medical solenoid valve, and a foot switch. The power supply unit is connected with the control unit, and the control unit is connected with the medical solenoid valve and the foot switch. The control unit comprises a voltage conversion circuit, an STM32F103 microcontroller, a solenoid valve drive control circuit and a foot switch signal collection circuit. The voltage conversion circuit is connected with the STM32F103 microcontroller, and the STM32F103 microcontroller is connected with the solenoid valve drive control circuit and the foot switch signal collection circuit. The solenoid valve drive control circuit is connected with the medical solenoid valve, and the foot switch signal collection circuit is connected with the foot switch. The medical solenoid valve is an intelligent proportional-control type (hygienic level) pneumatic diaphragm valve. The controller is reasonable in structural design, is stable and reliable, is convenient to operate, is easy to maintain, and is high in practicality.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a medical laparoscope exhaust foot switch controller Background technique [0002] Laparoscopic surgery has largely replaced traditional open surgery due to its advantages of less trauma, fine manipulation, quicker recovery, and less bleeding. In large comprehensive hospitals at home and abroad, the proportion of laparoscopic surgery accounts for more than 50% of all operations. However, the aerosol must be discharged in time due to the hemostasis caused by the ultrasonic scalpel cutting in laparoscopic surgery, so as not to blur the surgical field. At present, clinically, a surgical assistant is usually responsible for exhausting, which not only increases the number of manpower, but also causes a waste of human resources. More importantly, the exhausting of the surgical assistant cannot fully achieve the timely exhausting of the operator and maintain the intraperiton...
