Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a hysteroscope that facilitates detecting pathological points in the uterine cavity during clinical surgery. Background Art

[0002] A hysteroscope is a fiber optic light source endoscope used for examination and treatment in the uterine cavity, including a hysteroscope, an energy system, a light source system, an irrigation system, and an imaging system; it uses the front part of the mirror body to enter the uterine cavity and has a magnifying effect on the observed part, making it the preferred examination method for gynecological hemorrhagic diseases and intrauterine lesions intuitively and accurately. Since the uteruses of most women are anteverted, that is, the uterus faces the pubis, and an angle of 120° - 150° is formed between the cervix and the uterine body. Currently, the hysteroscope lens is horizontally arranged and cannot well detect the pathological points in the anteverted uterus.

[0003] Based on the above problems, the present invention proposes a hysteroscope that facilitates detecting pathological points in the uterine cavity during clinical surgery. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a hysteroscope that facilitates detecting pathological points in the uterine cavity during clinical surgery. By forming an angle of 30° between the endoscope lens and the horizontal direction, it is convenient for clinicians to directly see the positions of the two uterine horns in the uterine cavity through this angle and detect the situation in the uterine cavity.

[0023] Please refer to Figures 1-4 ,

[0024] The present invention discloses a hysteroscope for facilitating the detection of pathological points in the uterine cavity during clinical surgery, including an end seat 1, an endoscope lens seat 2, a limiter 3, an outer tube 4 and a connecting block 5. The connecting block 5 has a semi-cylindrical structure, and its semi-circular arc surface is connected to the inner wall of the outer tube 4. The inner end of the limiter 3 is connected to the outer end of the connecting block 5. The lower surface of the limiter 3 is flush with the lower surface of the limiter 3. A fixing groove 6 for fixing the endoscope lens seat 2 is provided on the outer side of the top of the limiter 3. An inclination angle is provided between the bottom surface of the fixing groove 6 and the horizontal direction; the end seat 1 is fixed to the outer end surface of the limiter 3; the inclination angle between the bottom surface of the fixing groove 6 and the horizontal direction is 30°, and the endoscope lens forms a 30° angle with the horizontal direction, which is convenient for clinical direct viewing of the positions of the two uterine cornua in the uterine cavity through this angle, and the situation in the uterine cavity can be detected.

[0025] Furthermore, a connecting groove 41 for connecting the limiter 3 is provided at the top of the outer end of the outer tube 4, and the bottom width of the connecting groove 41 is equal to the lower surface width of the limiter 3.

[0026] Furthermore, the limiter 3 includes a first limiting block 31 and a second limiting block 32. The outer diameter of the inner end of the first limiting block 31 is equal to the outer diameter of the outer tube 4, which can play a limiting role. The first limiting block 31 will not extend into the outer tube 4, and the outer diameters of the two are equal, so the connection is smoother and more beautiful; the inner end of the first limiting block 31 is connected to the outer end surface of the connecting groove 41; the outer end surface of the first limiting block 31 forms an inclined surface 33, and the included angle between the inclined surface 33 and the horizontal direction is 60°; the cross-section of the second limiting block 32 is in a right-angled triangle structure, and its inner right-angled surface is connected to the lower part of the outer wall of the inclined surface 33, and its outer right-angled surface is the bottom surface of the fixing groove 6; the lower surface of the second limiting block 32 is flush with the lower surface of the connecting block 5.

[0027] Furthermore, the end seat 1 includes an inclined seat 11 in a semi-circular shape and a vertical seat 12. The inner end bottom of the inclined seat 11 is connected to the outer end of the second limiting block 32. The inclined seat 11 is arranged parallel to the inclined surface 33. The inner wall of the inclined seat 11, the outer right-angle surface of the second limiting block 32, and the inclined surface 33 enclose the fixing groove 6, which can complete the limitation of the endoscope lens seat 2 and ensure that the included angle with the horizontal direction is 30° after installation. The bottom of the inclined seat 11 is connected to the top of the vertical seat 12. The vertical seat 12 is arranged along the vertical direction, and its outer diameter is equal to the outer diameter of the outer tube 4. The outer edge of the inner wall of the vertical seat 12 is connected to the outer end face of the outer tube 4, ensuring that after the outer end of the vertical seat 12 is connected to the outer tube 4, the outer end of the outer tube 4 can be closed.

[0028] Furthermore, an endoscope lens 21 is provided in the middle of the outer end face of the endoscope lens seat 2, and LED light sources 22 are provided on both sides of the outer end face of the endoscope lens seat 2. A lens hole 111 for the endoscope lens 21 to pass through is provided in the middle of the inclined seat 11, and light source holes 112 for the LED light sources 22 to pass through are provided on both sides of the inclined seat 11. The lens hole 111 on the inclined seat 11 facilitates the positioning of the endoscope lens 21 and installs it at the correct position with a 30° inward-tilting viewing angle. The two light source holes 112 on both sides are the positions where the LED light sources 22 are fixed. With the help of the light source, the clinical situation inside the uterine cavity can be clearly understood through the display of this lens.

[0029] Furthermore, a forceps channel hole 121 is provided in the middle of the vertical seat 12, and water outlet holes 122 are provided on both sides of the vertical seat 12. The forceps channel hole 121 is used for a foreign body forceps or scissors to enter during clinical exploration and sampling, and it is also the position of the water inlet. The two water outlet holes 122 on both sides are the water outlets. The inflow and outflow of water facilitate the clinical cleaning of the uterine cavity environment with a hysteroscopy medium such as normal saline, making the line of sight clearer.

[0030] Furthermore, connecting rods 34 are provided on both sides of the bottom of the second limiting block 32. The lower surface of the connecting rods 34 is connected to the bottom of the connecting groove 41, and the outer ends of the connecting rods 34 are connected to the upper part of the inner wall of the vertical seat 12. By providing the connecting rods 34, the limiter 3 and the end seat 1 can be more firmly fixed to the outer end of the outer tube 4, avoiding detachment during the operation.

[0031] Furthermore, the inner end of the endoscope lens 21 is connected to one end of a wire harness 7, and the other end of the wire harness 7 is connected to a hysteroscope converter through the inner cavity of the outer tube 4. The wire harness 7 is connected by three-layer transmission lines, and the non-welded three-layer transmission wire harness design facilitates that when using the hysteroscope clinically, it is not affected by the transmission signals of other various electronic products in the hospital, the signal transmission is more stable during the operation or inspection process, and the product has stronger seismic resistance during transportation.
