Description
Technical Field
[0001] The utility model relates to the technical field of hysteroscopes, and particularly to an inner sheath structure of a hysteroscope with both inspection and surgical functions. Background Art
[0002] Hysteroscope inspection and surgery are common gynecological diagnosis and treatment means, which allow doctors to directly observe the inside of the uterus and perform necessary treatment procedures. In traditional integrated hysteroscope systems, the instrument channel, water inlet, water outlet, and endoscope are usually integrated in the same round tube. Although such a design is simple and intuitive, it results in a relatively large volume of the entire hysteroscope. During surgery, cervical dilation is usually required, and patients usually need to be hospitalized. In addition, since all components are concentrated together, cleaning and disinfection are also more difficult, increasing the risk of cross-infection.
[0003] Moreover, when the existing inner sheath of the hysteroscope accurately inserts surgical instruments, due to the insufficient stability of the inner sheath structure, unexpected movement of the surgical instruments may occur during the operation, which not only affects the surgical efficiency but also may cause additional harm to the patient. Therefore, the need to improve the inner sheath structure of the hysteroscope, especially to improve its operation accuracy, use safety, and ease of cleaning, is particularly urgent. Summary of the Utility Model
[0004] In view of this, the utility model aims to provide an inner sheath structure of a hysteroscope with both inspection and surgical functions. Through an innovative sliding block and semi-tube design, more precise operation control is achieved, while the surgical process is simplified, the operation burden of medical staff is reduced, the cleanliness and durability of the equipment are improved, thereby enhancing the safety and success rate of the operation, and having important clinical application value.
[0005] The technical solution adopted by the utility model to solve its technical problems is: to provide an inner sheath structure of a hysteroscope with both inspection and surgical functions, including a sliding block; an irregular-shaped hole is provided in the middle of the sliding block; the upper part of the irregular-shaped hole is in the shape of a semi-circular hole, and trapezoids are respectively provided at both lower ends of the semi-circular hole; a spring and a protrusion are provided on the sliding block above the semi-circular hole; the spring is arranged in a circular hole on the sliding block above the semi-circular hole, the fixed end of the spring is connected to the sliding block, and the movable end of the spring is connected to the protrusion; the length of the spring is equal to the length of the circular hole on the sliding block; an arc-shaped section is provided in the middle of the irregular-shaped hole; a butterfly-shaped hole is provided at the lower part of the irregular-shaped hole.
[0006] Furthermore, the sliding block further includes a button with horizontal stripes for pushing the sliding block to move.
[0007] Further, it further includes an inner sheath connecting sleeve, a water inlet core, an inner sheath tube, a half tube, and a guiding groove; the water inlet core is connected to the side wall of the inner sheath connecting sleeve; the inner sheath tube is connected to the tail end of the inner sheath connecting sleeve; the half tube is sleeved on the outer wall of the inner sheath tube and fixedly connected to the inner sheath connecting sleeve.
[0008] Further, several grooves are provided on the half tube for clamping and fixing the position of the sliding block.
[0009] Further, it further includes an orientation tube. The orientation tube is arranged above the guiding groove. One end of the circular pipe of the orientation tube is sleeved on the front end of the inner sheath tube, and the other end is fixedly connected to the corresponding position of the special-shaped hole for ensuring the correct positioning of the guiding groove.
[0010] The beneficial effects of the present utility model are as follows:
