Problems solved by technology

At present, there is no special equipment for dealing with air bubbles in hysteroscopic surgery. The opening size of the input medium and output medium valves is mainly controlled by the surgeon manually. Skills are difficult to impart to novice doctors, and the effect of experienced doctors cannot be guaranteed every time
Moreover, the two valves are controlled separately, requiring both hands to operate separately, and the more common method of absorbing air bubbles is to quickly open the input and output valves at the same time. energy

Embodiment 1

[0032] Such as figure 1 As shown, a bubble suction device for electrosurgical surgery includes a PLC controller 3 as the core of the present invention, which controls the size of the valve opening and the switching speed of two medical electric proportional valves 1 and 2, and their linkage The mode is written in button group 6. The surgeon only needs to press the corresponding button in the button group 6 to obtain the set linkage mode, thus simplifying the difficulty of the operation and consolidating the successful experience.

[0033] One-touch multiple buttons (such as figure 2 The embodiment shown is a 3X3 button row), and the function of each button can be customized by the user. The parameters that can be controlled are: the opening size of the input valve, the opening size of the output valve, the opening change speed of the input valve, and the opening change speed of the output valve.

[0034] The function of one of the buttons is to quickly open large input and output...

Abstract

The invention discloses a bubble adsorbing and removing device for electrocision, and relates to the technical field of hysteroscope electrocision devices. The bubble adsorbing and removing device comprises a PLC controller, a button set and at least two medical electric proportional valves, wherein the button set is used for controlling the opening size and the opening and closing speed of the medical electric proportional valves through the PLC controller, a linkage mode of the medical electric proportional valves is stored, and one-button starting is achieved through one button in the button set. Automatic one-key bubble adsorbing and removing is developed through a control device, the operation intensity of a surgeon can be reduced through repeated automatic operation, the bubble retention time in a hysteroscope operation is shortened, the risk of aeroembolism in the operation is reduced, and the safety of the operation is improved.

Description

Technical field [0001] The invention relates to the technical field of hysteroscope electric resection surgical instruments, in particular to a bubble suction instrument used for electrical resection surgery. Background technique [0002] Hysteroscopy technology utilizes the human body’s natural passageway, namely vagina-cervix, uses external light sources, optical fibers, electronic equipment, and uterine expansion media, to look directly at the lesions located in the vagina, cervix, uterine cavity, and fallopian tube openings, and use related instruments to perform surgical operations. Minimally invasive endoscopy technology. Since its first development in the 19th century, hysteroscopy has gradually replaced traditional surgery with its advantages of wide adaptability and minimally invasiveness, bringing revolutionary changes to the diagnosis and treatment of many intrauterine diseases. Hysteroscopy technology has a wide range of indications, and it has been widely used in cl...
