Description

Technical Field

[0001] This utility model relates to the field of gynecological instrument technology, specifically a dual-channel hysteroscope. Background Technology

[0002] Hysteroscopy includes a scope, an energy system, a light source system, an irrigation system, and an imaging system. It uses the front part of the scope to enter the uterine cavity, providing a magnification effect on the observed area. It is the preferred examination method for gynecological bleeding disorders and intrauterine lesions due to its intuitive and accurate nature.

[0003] However, traditional hysteroscopy often uses a single-channel approach. After the lesion is identified, the surgical instruments are inserted into the patient's body through a single channel for operation. When multiple instruments need to be operated together, the two instruments are prone to collision and conflict when located in the same channel, which has an adverse effect on the operation. Utility Model Content

[0004] The purpose of this invention is to provide a dual-channel hysteroscope to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-channel hysteroscope, comprising a scope body, and further comprising,

[0006] Connecting pipe two, a return pipe is fixedly connected to one side of the connecting pipe two, a partition is fixedly connected to the top of the inner wall of the return pipe, an inner pipe is fixedly connected to the bottom of the partition, a sealing gasket is fixedly connected to the side of the connecting pipe two away from the return pipe, and the inner side of the sealing gasket is fixedly connected to one end of the return pipe.

[0007] A connecting pipe is fixedly connected to one side of the endoscope body. The return pipe passes through the sliding connection connecting pipe and the inner wall of the endoscope body. The side of the connecting pipe away from the sealing gasket ring is attached to the side of the connecting pipe away from the endoscope body.

[0008] Preferably, an inlet valve is fixedly connected to the top of the first connecting pipe.

[0009] Preferably, a drain valve is fixedly connected to the bottom of the second connecting pipe, a through hole is opened at the bottom of the inner pipe, a through hole is opened at the bottom of the return pipe, a drain hole is opened at the bottom of the second connecting pipe, and the drain hole is located at the top of the drain valve and communicates with the inside of the drain valve.

[0010] Preferably, a light source interface is fixedly connected to the bottom of the mirror body.

[0011] Preferably, a camera interface is fixedly connected to the bottom of the mirror body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, by setting an inner tube and a partition, allows two instruments to be inserted into the inner tube and the gap between the return tube and the inner tube respectively. The two instruments will not conflict when inserted and removed, and the instrument located in the gap between the return tube and the inner tube has a large space for position adjustment, making it easier to adjust the angle and position, thus improving the convenience of operation. It solves the problem that traditional hysteroscopy often uses a single channel, where after the lesion is identified, surgical instruments are inserted into the patient's body through a single channel for operation. When multiple instruments need to be operated together, the two instruments located in the same channel are prone to collision and conflict, which adversely affects the operation.

[0014] This invention features through-hole one and through-hole two. When the drain valve is opened, excess swelling fluid flows through the return pipe and inner pipe to through-hole one and through-hole two, then flows downward into connecting pipe two and into the drain valve through the drain hole, and finally is discharged, reducing the amount of external leakage.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a dual-channel hysteroscope, including a scope body 1, and further comprising,

[0023] Connecting pipe 2 3, a return pipe 4 is fixedly connected to one side of connecting pipe 2 3, a partition 6 is fixedly connected to the top of the inner wall of the return pipe 4, an inner pipe 7 is fixedly connected to the bottom of the partition 6, a sealing gasket 5 is fixedly connected to the side of connecting pipe 2 3 away from the return pipe 4, and the inner side of the sealing gasket 5 is fixedly connected to one end of the return pipe 4.

[0024] One side of the microscope body 1 is fixedly connected to a connecting tube 2. The return pipe 4 passes through the sliding connection connecting tube 2 and the inner wall of the microscope body 1. The side of the connecting tube 3 away from the sealing gasket 5 is attached to the side of the connecting tube 2 away from the microscope body 1.

[0025] The top of the connecting tube 2 is fixedly connected to an inlet valve 12 for inputting distending fluid;

[0026] The bottom of the connecting tube 2 3 is fixedly connected to the drain valve 11. The bottom of the inner tube 7 is provided with a through hole 8. The bottom of the return tube 4 is provided with a through hole 9. The bottom of the connecting tube 2 3 is provided with a drain hole 10. The drain hole 10 is located at the top of the drain valve 11 and is connected to the inside of the drain valve 11. Excess distending fluid in the patient's body is discharged through the return tube 4 and the inner tube 7 to the through hole 8 and the through hole 9 and flows down into the connecting tube 2 3. Then it flows into the drain valve 11 through the drain hole 10, reducing the amount of leakage.

[0027] A light source interface 13 is fixedly connected to the bottom of the mirror body 1 for connecting to a light source system;

[0028] The bottom of the mirror body 1 is fixedly connected to a camera interface 14 for connecting to a camera system.

[0029] Working principle: Connect the light source system to the light source interface 13, connect the camera system to the camera interface 14, connect the inlet tube to the inlet valve 12 to input distending fluid, and connect the drain tube to the drain valve 11. Slowly insert the return tube 4 into the connecting tube 2 and the endoscope 1, so that the connecting tube 3 fits against the connecting tube 2. Slowly insert the endoscope 1 into the patient's body, open the inlet valve 12 to input distending fluid into the patient's uterine cavity, so that the tip of the endoscope 1 is located in the patient's uterine cavity, and supplemental light and images are taken of the lesions in the patient's body. Transmit the images to external equipment. Then open the drain valve 11. Excess distending fluid flows through the return tube 4 and the inner tube 7 to the through hole 8 and through hole 9, and then flows down into the connecting tube 3 and into the drain valve 1 through the drain hole 10. After identifying the lesion, two instruments are inserted into the inner tube 7 and the gap between the return tube 4 and the inner tube 7, respectively. The two instruments do not conflict when inserted and removed, and the instrument located in the gap between the return tube 4 and the inner tube 7 has a large space for position adjustment, making it easier to adjust the angle and position and improving the convenience of operation. This solves the problem that traditional hysteroscopy often uses a single channel, where surgical instruments are inserted into the patient's body through a single channel after identifying the lesion. When multiple instruments need to be operated together, the two instruments located in the same channel are prone to collision and conflict, which will adversely affect the operation. The light source system, camera system and infusion and drainage system all use existing technology, and the corresponding structures are embedded in the endoscope body 1 and the return tube 4.
