Novel uterine dilatation machine and control method thereof

Abstract

The invention discloses a novel uterine dilatation machine and a control method thereof. The novel uterine dilatation machine comprises a pressure sensor, a motor, a lifting supporting device and a controller, wherein the motor is connected with the lifting supporting device, the pressure sensor is connected with the controller, and the controller is connected with the motor. The pressure sensor connected to the end, close to the uterus, of an infusion tube detects uterine distention hydraulic pressure data of the uterus and transmits the uterine distention hydraulic pressure data to the controller, then the uterine distention hydraulic pressure data transmitted by the controller are compared with preset uterine distention pressure, and the lifting supporting device is driven to ascend anddescend by controlling the motor to rotate positively and negatively, so that constant uterine distention hydraulic pressure consistent with preset uterine distention pressure is obtained, gas embolism is effectively prevented, the uterine distention hydraulic pressure can be kept constant in real time, and the quality of hysteroscopic surgery is improved.

Description

Technical field [0001] The invention relates to a new type of uterine swelling machine and its control method. Background technique [0002] Hysteroscopy is widely used in the diagnosis and treatment of gynecological diseases. Dilation machine is an indispensable equipment in hysteroscopy and treatment. At present, OLYMPUS and STORZ are widely used clinically. The device is a rotating body. The rotating body is equipped with a cam. The part of the tube that transports the uterine fluid passing through the rotating body will be squeezed to the position of the cam. There is no gap, and between the two cams, because there is no squeezing and expanding into a space, the rotating body rotates to continuously transport the uterine dilatation fluid from one end to the other end, thereby achieving the effect of uterine dilation. The “active aspiration” method of uterine dilation by the uterine dilation machine is prone to actively suck gas into the uterine cavity when the amount of flu...

AI Technical Summary

Problems solved by technology

The "active suction" uterine distension method of the uterine expander is easy to actively suck gas into the uterine cavity when the amount of liquid is insufficient or in other situations, which may lead to gas embolism, a serious complication of hysteroscopic surgery. deadly

Moreover, because the existing uterine distension machine is not very precise in controlling the pressure of uterine distension, it is easy to cause adverse effects on the quality of hysteroscopic surgery.
