AI Technical Summary
Existing flexible lens front-ends are difficult to design to simultaneously meet the requirements of small outer diameter and large working channel, while ensuring structural stability and strength.
A soft-lens front end head was designed, which adopts a cylindrical shell structure, sets through and non-through channels, and fixes the snake bone with a retaining wall, side limiting plate and lower limiting plate to enhance structural stability and reduce weight.
While meeting the requirements of small outer diameter and large working channel, the structure stability and strength of the front end head have been improved, thus adapting to the needs of endoscope use.

Abstract
Claims
1. A flexible lens tip, comprising a cylindrical housing, the housing including a front end and a rear end; characterized in that: A non-penetrating circular rear hole is provided extending from the rear end to the front end along the axial direction of the housing; a through circular working channel is provided along the axial direction of the housing, and a non-penetrating instrument tube channel is provided along the axial direction of the working channel, the cross-section of the instrument tube channel being a circle with a diameter larger than the cross-sectional diameter of the working channel; a through lens module channel is provided above the working channel along the axial direction of the housing; a non-penetrating LED channel is provided on each side of the lens module channel along the axial direction of the housing; a plate-shaped baffle is provided between the working channel and the lens module channel, the baffle being located inside the rear hole and connected to the inner wall of the housing at both ends, and an arc-shaped side limiting plate is provided at each end of the baffle extending downward along the inner wall of the housing; an arc-shaped lower limiting plate is also provided on the lower side of the inner wall of the housing; the side limiting plates and the lower limiting plate are used to fix the snake bone.
2. A soft scope style front end as claimed in claim 1, wherein, The lengths of the retaining wall, side limiting plate, and lower limiting plate are all less than the depth of the rear hole.
3. A soft mirror nosepiece according to claim 1, wherein Two horn-shaped weight-reducing holes are symmetrically arranged between the side limiting plate and the working channel. The weight-reducing holes are blind holes.
4. A soft scope style front end as claimed in claim 1, wherein, The cross-section of the lens module channel is square.
5. A soft mirror nosepiece according to claim 1, wherein, The thickness of the retaining wall is 0.11 mm.
6. A soft mirror nosepiece according to claim 1, wherein, The front end includes a first surface perpendicular to the axis of the housing and a second surface inclined to the axis of the housing.
7. A soft mirror nosepiece according to claim 1, wherein A limiting groove is provided on each side of the upper surface of the retaining wall.
