Description

Technical Field

[0001] The utility model relates to the technical field of hysteroscopic surgical instruments, and more specifically to a hysteroscopic water pipe with an exhaust device. Background Art

[0002] Hysteroscopy is a new, minimally invasive gynecological diagnostic and treatment technology. It is a fiber-light endoscope used for intrauterine examination and treatment. It includes a hysteroscope, an energy system, a light system, a perfusion system and an imaging system. It uses the front part of the scope to enter the uterine cavity and has a magnifying effect on the observed area. It has become the preferred examination method for gynecological hemorrhagic diseases and intrauterine lesions with its intuitive and accurate nature.

[0003] The water tube of the hysteroscope currently used is usually a Y-shaped tube, one side of the upper end is connected to the liquid bag, and the other side is connected to the instrument. The gas in the water tube must be emptied each time a connection is made. If bubbles enter the uterine cavity, it will cause air embolism. Application No. 202023075564.1 is a gas filtration device in a clinical hysteroscopic surgical perfusion system, which provides an idea to solve the bubble problem by setting a filter bottle. Although the problem of entering bubbles can be solved, this type of equipment relies on the exhaust pipe and the air blocking clamp. It is difficult to control the volume of the filtrate to 2 / 3 of the volume of the filter bottle (the ratio will be adjusted according to actual needs). The feasibility is poor and it is difficult to put into actual use. Further structural improvement is still needed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a hysteroscope water pipe with an exhaust device in view of the above-mentioned defects of the prior art.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A hysteroscopic water pipe with an exhaust device is constructed, comprising a Y-tube and a filter container, wherein the lower end of the filter container is connected to a liquid outlet pipe, wherein the upper end of the filter container is provided with an opening and a circular plate closing the opening; the circular plate is provided with an exhaust hole and a connecting joint detachably connected to the liquid outlet end of the Y-tube; the lower end of the circular plate is connected to a catheter, the inner hole of the catheter is directly opposite to and connected to the exhaust hole, and the aperture of the inner hole of the catheter is larger than the aperture of the exhaust hole; a sliding rod is longitudinally slidably arranged in the catheter, the lower end of the sliding rod is provided with a float, and the upper end is provided with a sealing gasket closing the exhaust hole, and the outer diameter of the sealing gasket is smaller than the aperture of the inner hole of the catheter.

[0007] The utility model discloses a hysteroscopic water pipe with an exhaust device, wherein the inner wall of the pipe is provided with a cross-shaped bracket, and the center of the bracket is provided with a sliding sleeve for the sliding rod to slide.

[0008] The hysteroscopic water tube with an exhaust device described in the utility model is characterized in that a plurality of air holes are arranged on the peripheral surface of the tube, and the air holes are communicated with the inner hole of the tube.

[0009] The hysteroscopic water tube with an exhaust device described in the utility model, wherein a plug body for sealing the exhaust hole is arranged at the exhaust hole.

[0010] The hysteroscopic water pipe with an exhaust device described in the utility model, wherein the filtering container further comprises a flexible bag body, and the circular plate is arranged on the upper end of the bag body.

[0011] The hysteroscopic water pipe with an exhaust device described in the utility model is characterized in that a hanging part is arranged on the circular plate.

[0012] The hysteroscopic water pipe with exhaust device described in the utility model, wherein the connecting joint is a connecting pipe penetrated through the circular plate, and a conical guiding portion is arranged at the upper end of the connecting pipe.

[0013] The hysteroscopic water pipe with an exhaust device described in the utility model is characterized in that a dust plug is provided on the upper cover of the guide portion.

[0014] The beneficial effect of the utility model is that: by using the hysteroscopic water tube of the present application, the air can be discharged well, and the liquid level inside the filter container can be controlled by the float. When the liquid level is lower than the set height, the float drops, driving the sliding rod downward, and the sealing gasket opens the exhaust hole, so that the liquid in the Y-tube flows into the filter container. Conversely, when the liquid level rises to the point where the sealing gasket closes the exhaust hole, the air pressure in the filter container increases, and the liquid in the Y-tube cannot flow into the filter container, thereby solving the problems of exhaust and liquid level control and enabling the entire device to be implemented.
