DETAILED DESCRIPTION OF THE INVENTION
[0022] The present utility model will be further described below:
[0023] Please refer to Figures 1-4 ,
[0024] The utility model discloses a front end head of a cystoscope, which includes a front end head body 1. The front end head body 1 is in a cylindrical structure. A camera mounting hole 3 for mounting a camera 2 is arranged above the axial direction of the front end head body 1, and an instrument channel hole 4 arranged along the horizontal direction is arranged below the axial direction of the front end head body 1. The upper part 11 of the front end face of the front end head body 1 is arranged along the vertical direction, and the lower part 12 of the front end face is inclined. The bottom end of the lower part 12 of the front end face inclines backward. The front end of the camera mounting hole 3 is arranged on the upper part 11 of the front end face. The front end of the instrument channel hole 4 is arranged on the lower part 12 of the front end face. In this case, a surgical operation forceps is installed through the instrument channel hole 4, and the camera 2 is installed in the camera mounting hole 3. And because the lower part 12 of the front end face is inclined and the bottom end of the lower part 12 of the front end face inclines backward, when the surgical operation forceps enters the human body, the damage to the inner wall of the human body cavity can be reduced. Preferably, the included angle between the lower part 12 of the front end face and the horizontal direction is 65°.
[0025] Furthermore, a circular groove 5 is arranged on the rear end face 13 of the front end head body 1. The inner diameter of the circular groove 5 is smaller than the outer diameter of the front end head body 1. Above the front end wall of the circular groove 5, an integrated groove 6 roughly in a semicircular shape is arranged. The camera mounting hole 3 is arranged in the middle of the front end of the integrated groove 6. The rear end of the instrument channel hole 4 passes through the middle of the lower part of the front end wall of the circular groove 5. By arranging the circular groove 5, it is convenient to perform positioning connection with the cystoscope snake bone.
[0026] Furthermore, a camera seat 7 matching the cross-sectional shape thereof is arranged in the integrated groove 6. The camera 2 is arranged in the middle of the front end of the camera seat 7. Lighting lamps 8 are fixed on both sides of the front end of the camera seat 7. The lighting lamps 8 do not penetrate the front end face. The hidden design can make the use safer and less current contacts the human body.
[0027] Furthermore, a transparent plate is arranged on the front end face in front of the lighting lamp 8. The transparent plate is embedded in the upper part 11 of the front end face. The transparent plate is in a forwardly convex arc structure, ensuring that the lighting light can play a better lighting role; the transparent plate is in a forwardly convex arc structure, making the light more concentrated.
[0028] Furthermore, the instrument channel hole 4 is in a circular structure. 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 outer tube 14 of the surgical operation forceps is sleeved in the instrument channel hole 4, and the surgical operation forceps located in the outer tube 4 can pass through the limiting ring 41 and extend out of the front end head body 1; the limiting ring 41 can play a role of positioning and limiting, ensuring that the installation position of the outer tube 14 of the surgical operation forceps is fixed.
[0029] Furthermore, by providing a communication groove 9 between the middle of the top of the instrument channel hole 4 and the middle of the bottom of the integration groove 6, the bottom of the camera holder 7 in the integration groove 6 can be connected to the top of the outer tube 14 with glue, making the fixation of the camera holder 7 and the outer tube 14 more stable; and ensuring that the outer tube 14 does not rotate.
[0030] Furthermore, on both sides of the inner wall of the circular groove 5, there are square connection limiting blocks 10. When the front end body 1 is connected to the cystoscope cobra bone, there will be no change in position, keeping the operation channel fixed and the operation cavity of the surgery unchanged.
[0031] During installation, the camera holder 7 is inserted into the integration groove 6 from the rear end, and the camera holder 7 and the integration groove 6 are adhered with glue; the outer tube 14 is adhered to the instrument channel hole 4 with glue, and then the bottom of the camera holder 7 in the integration groove 6 and the top of the outer tube 14 are adhered with glue in the communication groove 9; finally, the front end of the cystoscope cobra bone is inserted into the circular groove 5, and there is a limiting groove on the front end of the cystoscope cobra bone that is matched and engaged with the connection limiting block 10, and the two are adhered with glue after insertion.
[0032] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent transformation made by using the content of the specification and drawings of the present invention, or any direct or indirect application in related technical fields, shall be equally included in the patent protection scope of the present invention.
