Description

Technical Field

[0001] This utility model relates to a front end head, and more particularly to an endoscope tip head. Background Technology

[0002] The endoscope head, also known as the tip, is the head structure of the endoscope. It houses the camera and LEDs and has a pre-installed working channel. The endoscope head is glued to the skeletal frame. To meet design requirements, the outer diameter of the endoscope head should be as small as possible, while the working channel should be as large as possible, but the overall structure must also have sufficient strength to avoid excessively thin areas that could affect its normal operation. Therefore, the industry meticulously designs the layout of the camera, LEDs, and working channel to meet these requirements. Utility Model Content

[0003] The purpose of this invention is to provide an endoscope tip that solves or partially solves the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An endoscope tip includes a cylindrical housing with a front end and a rear end. A circular through-hole lens module channel is provided on the housing along its axial direction. A circular through-hole working channel is provided directly below the lens module channel along the axial direction of the housing. A square-hole cable channel is provided on the housing along its axial direction, coaxial with the lens module channel and extending from the rear end to the front end to a first length, which is less than the length of the housing. Two side holes are provided on the housing along its axial direction, symmetrically arranged on both sides of the cable channel, extending from the rear end to the front end to a second length, which is less than the first length. LED channels are provided at positions corresponding to the two side holes, extending along the axial direction of the housing and from the rear end to the front end to a third length, which is greater than the second length and less than the length of the housing.

[0006] Preferably, two arc-shaped slots are symmetrically arranged on the outer wall of the housing, the slots extending from the rear end to the front end to a fifth length, the fifth length being less than the length of the housing; the slots are arranged on both sides of the housing.

[0007] Preferably, the depth of the card slot is greater than 0.11 mm.

[0008] Preferably, the arc of the card slot is 60°.

[0009] Preferably, there is a gap between the cable channel and the instrument tube channel, and the gap is greater than 0.11 mm.

[0010] Preferably, an instrument tube channel is provided on the housing along the axial direction of the housing. The instrument tube channel is coaxial with the working channel and extends from the rear end to the front end to a fourth length, which is less than the length of the housing.

[0011] Preferably, the cross-section of the instrument tube channel is circular, and the diameter of the instrument tube channel is larger than the diameter of the working channel.

[0012] The beneficial effects of this utility model are: the structural design allows it to meet the design requirements of the lens module channel and the instrument tube channel; the cable channel and the instrument tube channel have a gap, forming a retaining wall structure, which can separate the cable channel and the instrument tube channel and increase the strength of the front end.

[0017] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0018] In the description of this utility model, it should be noted that the terms "inner", "outer", "upper", "lower", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figures 1 to 4 As shown, the endoscope tip of this utility model includes a cylindrical housing 10, which includes a front end 12 and a rear end 14. A circular through-hole lens module channel 16 is provided on the housing 10 along the axial direction of the housing 10; a circular through-hole working channel 18 is provided directly below the lens module channel 16 along the axial direction of the housing 10.

[0020] A square-hole-shaped cable channel 20 is provided on the housing 10 along the axial direction of the housing 10. The cable channel 20 is coaxial with the lens module channel 16 and extends from the rear end 14 to the front end 12 to a first length, which is less than the length of the housing 10.

[0021] Two side holes 22 are provided on the housing 10 along the axial direction of the housing 10. The two side holes 22 are symmetrically arranged on both sides of the cable channel 20. The side holes 22 extend from the rear end 14 to the front end 12 to a second length, which is less than the first length. The side holes 22 connect to the cable channel 20. LED channels 24 are provided at the positions corresponding to the two side holes 22. The LED channels 24 are arranged along the axial direction of the housing 10 and extend from the rear end 14 to the front end 12 to a third length, which is greater than the second length and less than the length of the housing 10. The cross-section of the LED channel 24 is square.

[0022] Two arc-shaped slots 26 are symmetrically arranged on the outer wall of the housing 10. The slots 26 extend from the rear end 14 to the front end 12 to a length of five, which is less than the length of the housing 10. The slots 26 are arranged on both sides of the housing 10 and are used to fix the snake bone.

[0023] The depth of the card slot 26 is greater than 0.11 mm; the curvature of the card slot 26 is 60°.

[0024] An instrument tube channel 28 is provided on the housing 10 along the axial direction of the housing 10. The instrument tube channel 28 is coaxial with the working channel 18 and extends from the rear end 14 to the front end 12 to a fourth length, which is less than the length of the housing 10. There is a gap between the cable channel 20 and the instrument tube channel 28, which is greater than 0.11 mm.

[0025] The instrument tube channel 28 has a circular cross-section and is used to hold the instrument tube. The diameter of the instrument tube channel 28 is larger than the diameter of the working channel 18, thus forming a stepped structure, which can limit the movement of the instrument tube.
