Description

Technical Field

[0001] This utility model relates to the field of hysteroscopy technology, specifically to a balloon-type dilator hysteroscope. Background Technology

[0002] Hysteroscopy is a new, minimally invasive gynecological diagnostic and treatment technique. It is a fiber optic endoscope used for examination and treatment within the uterine cavity. It has become the preferred examination method for gynecological bleeding disorders and intrauterine lesions. Hysteroscopy can determine the location, size, appearance, and extent of lesions.

[0003] A search revealed that patent application CN219250120U discloses a balloon-type dilator hysteroscope, comprising a sleeve collar block, with a speculum rotating cylinder embedded inside the sleeve collar block. A front camera is embedded at one end of the speculum rotating cylinder, and a linkage component is embedded on the outer wall of the speculum rotating cylinder near the front camera. The linkage component includes a side camera embedded on the outer wall of the speculum rotating cylinder near the front camera. This facilitates a full-angle examination of the uterine cavity wall, improving convenience.

[0004] However, due to the design of the endoscope's rotating tube and front camera, it is inconvenient to use it in conjunction with other surgical instruments after the endoscope's rotating tube is inserted into the uterine cavity. The structure is complex and the operation is inconvenient. At the same time, when encountering patients with a loose cervix, the distending fluid is prone to leakage, resulting in poor distending effect, unclear images, and thus the operation cannot be carried out smoothly.

[0005] Therefore, we propose a balloon-type dilatational hysteroscopy. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a balloon-type dilator hysteroscope, which solves the problems of inconvenient operation and easy leakage of distension fluid in existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a balloon-type dilator hysteroscope, comprising a hysteroscope tube, wherein the interior of the hysteroscope tube is hollow;

[0008] A lens sleeve of the same specification is fixedly installed on the outer wall of the right side of the hysteroscopy tube. Four sets of cameras A are fixedly installed on the front side of the lens sleeve. Four sets of connecting rods are fixedly installed on the left side of the hysteroscopy tube. A fixing seat is fixedly installed on the left end of the connecting rod. A through hole is opened on the left side of the fixing seat. The diameter of the through hole is the same as the diameter of the opening on the left side of the hysteroscopy tube, and the center of the through hole is coaxial with the hysteroscopy tube.

[0009] An air balloon sleeve is fixedly installed on the outer wall of the hysteroscopic tube, and an inflation tube connected to the air balloon sleeve is fixedly installed on the inner wall of the hysteroscopic tube. The inflation tube extends from the left side of the through hole, and an inflation head is fixedly installed at the left end of the inflation tube. An air release valve is fitted on the outer wall of the inflation tube, and a leak-proof plug of the appropriate size is fixedly installed on the outer wall of the left side of the hysteroscopic tube.

[0010] Preferably, the diameter of the hysteroscopic tube gradually decreases from left to right, which facilitates the insertion of the hysteroscopic tube into the cavity.

[0011] Preferably, the outer wall of the hysteroscopic tube is fitted with a leak-proof cotton located between the leak-proof plug and the balloon sleeve, so as to absorb the distending fluid that leaks out from the balloon sleeve.

[0012] Preferably, the right side of the anti-leakage plug has an annular groove, which can collect the uterine distension fluid, prevent leakage from the anti-leakage plug, and improve the uterine distension effect.

[0013] Preferably, the leak-proof plug, airbag sleeve, and lens sleeve are made of silicone material for support, which can improve the comfort of inserting the device into the body and reduce irritation.

[0014] Preferably, four sets of cameras B positioned opposite each other are fixedly installed on the outer wall of the lens cover, which facilitates observation of the side of the uterine cavity.

[0015] 1. This balloon-type dilator hysteroscope, with its hysteroscope tube, lens sleeve, and fixation base, features a camera mounted on the lens sleeve. The hysteroscope tube is coaxial with and communicates with the through hole on the fixation base. After the hysteroscope tube is inserted into the uterine cavity, surgical instruments can be inserted into the hysteroscope tube through the through hole and exit from the right side of the lens sleeve to perform surgery inside the uterine cavity. The operation is simple and convenient.

[0016] 2. Simultaneously, through the setting of the balloon sleeve, inflation head, and anti-leak plug, the balloon sleeve is first inflated by pressing the inflation head. The balloon sleeve inflates and fits against the inner wall of the uterine cavity to prevent the leakage of distending fluid. The anti-leak plug seals the outside of the cervix. The two lines of defense can seal the uterine cavity to the greatest extent and improve the distending effect. Attached Figure Description
