Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a front end head of a hysteroscope which is convenient for clinical operation observation. Background Art

[0002] The hysteroscope is a new minimally invasive gynecological diagnosis and treatment technology, which is a fiber optic endoscope for intrauterine examination and treatment. At present, the front end face of the front end head of the hysteroscope is usually a vertical plane. When medical staff operate the surgical forceps for surgery, the end of the surgical forceps will be in full contact with the cavity surface, increasing the probability of damage to the cavity by the surgical forceps; in addition, the camera and the surgical forceps are usually arranged in parallel. When the surgical forceps extend less, the camera will have a blind area and cannot see the position of the surgical forceps.

[0003] Based on the above problems, the utility model provides a front end head of a hysteroscope which is convenient for clinical operation observation. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a front end head of a hysteroscope which is convenient for clinical operation observation. The front end face and the rear end face of the front end head body are inclined planes arranged in parallel, and the bottom of the front end face inclines backward, so that when the operator operates the surgical forceps for surgery, the protrusion can be minimized, reducing the probability of damage to the cavity; the camera mounting hole is arranged obliquely, and through the design of the oblique angle and the matching of the camera image, medical staff can see the surgical operating forceps faster.

[0005] In order to achieve the purpose of the utility model, the technical scheme adopted by the utility model is as follows:

The front end head body has a cylindrical structure. A camera mounting hole for installing a camera is arranged above the axis of the front end head body. The camera mounting hole is arranged obliquely. An instrument channel hole is arranged below the axis of the front end head body along the horizontal direction; the front end face and the rear end face of the front end head body are inclined planes arranged in parallel, and the bottom of the front end face inclines backward.

[0007] Square lighting holes are arranged on both sides above the rear end face. The inner wall of the lighting hole is communicated with the two side walls of the camera mounting hole. The two side lighting holes and the camera mounting hole form a "convex" shaped structure.

[0008] A transparent plate is arranged at the front end of the lighting hole. The transparent plate is embedded in the front end face. The transparent plate has a forward convex arc structure.

[0009] The instrument passage hole has a circular structure. A limiting ring is provided at the front end of the instrument passage hole. The outer diameter of the limiting ring is equal to the inner diameter of the instrument passage hole, and the inner diameter of the limiting ring is smaller than the inner diameter of the instrument passage hole.

[0010] The included angle between the front end face and the horizontal direction is 75.5°, and the included angle between the rear end face and the horizontal direction is 104.5°.

[0019] The following further describes the present utility model:

[0020] Please refer to Figures 1-3 ,

[0021] The utility model discloses a front end head of a hysteroscope which is convenient for clinical surgical operation observation, including a front end head body 1. The front end head body 1 is of a cylindrical structure. An image sensor mounting hole 3 for mounting an image sensor 2 is arranged above the front end head body 1 in the axial direction. The image sensor mounting hole 3 is arranged obliquely. An instrument channel hole 4 is arranged below the front end head body 1 along the horizontal direction. The image sensor 2 is mounted in the image sensor mounting hole 3, and surgical tools such as surgical forceps are mounted in the instrument channel hole 4. The front end face 11 and the rear end face 12 of the front end head body 1 are parallel inclined planes, and the bottom of the front end face 11 inclines backward. When an operator operates the surgical forceps for surgery, the protrusion can be minimized, reducing the probability of damage to the cavity. The image sensor mounting hole 3 is arranged obliquely. Through the design of the bevel angle and the matching of the image sensor image, medical staff can see the surgical forceps faster. Preferably, the included angle between the front end face 11 and the horizontal direction is 75.5°, and the included angle between the rear end face 12 and the horizontal direction is 104.5°. The image sensor mounting hole 3 is of a square structure, and the included angle between the axial direction of the image sensor mounting hole 3 and the axial direction of the instrument channel hole 4 is 14.5°.

[0022] Further, on both sides above the rear end face 12, there are square lighting holes 5. The inner wall of the lighting hole 5 is communicated with the two side walls of the image sensor mounting hole 3. The two side lighting holes 5 and the image sensor mounting hole 3 form a "convex" - shaped structure. The lighting hole 5 is open at the rear end and blocked at the front end. Such a hidden design can make the use safer and reduce the contact of current with the human body. The inner wall of the lighting hole 5 is communicated with the two side walls of the image sensor mounting hole 3, so that the lighting lamp can be integrated with the image sensor 2 for installation.

[0023] Further, a transparent plate is arranged at the front end of the lighting hole 5. The transparent plate is embedded in the front end face 11 to ensure that the lighting light can play a better lighting role. The transparent plate is of a forward - convex arc structure, making the light more concentrated.

[0024] Further, the instrument channel hole 4 is of a circular structure, which is convenient for installing tools such as surgical forceps. A limiting ring 41 is arranged at the front end of the instrument channel hole 4. The outer diameter of the limiting ring 41 is equal to the inner diameter of the instrument channel hole 4, and the inner diameter of the limiting ring 41 is smaller than the inner diameter of the instrument channel hole 4. The limiting ring 41 can play a role of positioning and limiting to ensure the fixed installation position of the surgical forceps.

[0025] Further, a connecting block 6 is arranged below the rear end face 12. The connecting block 6 is of a square structure, and a clamping groove 61 which is a hollow square structure with openings at the rear end and the top end is arranged at its top. A connecting hole 62 which is communicated with the instrument channel hole 4 is arranged at the bottom of the connecting block 6. The connecting hole 62 is coaxial and of the same diameter as the instrument channel hole 4, which is convenient for connecting the front end head to the hysteroscope.

[0026] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent transformation made by using the content of the specification and drawings of the present utility model, or any direct or indirect application in related technical fields, shall similarly be included within the patent protection scope of the present utility model.
