AI Technical Summary
Existing endoscope tips, while meeting the requirements of small outer diameter and large working channel, struggle to guarantee structural strength, leading to instability in use.
Design an endoscope tip with an external slot structure, including a cylindrical shell with symmetrical arc-shaped slots on the outer side wall, and a lens module channel, working channel and instrument tube channel inside, which are separated by a retaining wall and slots to increase strength. At the same time, LED channels and weight reduction holes are set on the shell to optimize the structure.
This design achieves full utilization of internal space while ensuring a fixed outer diameter, providing ample storage space for the lens module and instrument tubes, and increasing the overall structural strength and stability.

Abstract
Claims
1. An endoscope tip of an outer slot structure, comprising a cylindrical housing, the housing comprising a front end and a rear end; characterized in that: Two arc-shaped slots are symmetrically arranged on the outer side wall of the housing, extending from the rear end to the front end along the axial direction of the housing to a first length; a through lens module channel is arranged on the upper part of the housing along the axial direction; a through working channel is arranged on the lower part of the housing along the axial direction, the working channel having a circular cross-section; a non-through instrument tube channel is arranged on the lower part of the housing along the axial direction, the instrument tube channel being coaxial with the working channel, the instrument tube channel having a circular cross-section with a diameter larger than the working channel's cross-section diameter; a retaining wall is provided between the lens module channel and the working channel, the retaining wall having a slot, both the instrument tube channel and the slot extending from the rear end to the front end to a second length; the first length is less than the length of the housing, and the second length is 1 / 3 of the housing length.
2. An endoscope tip according to claim 1, wherein The cross-section of the lens module channel is square.
3. The endoscope tip with an external slot structure according to claim 2, characterized in that, The lens module channel is an inwardly expanding flared structure.
4. The endoscope tip of claim 1, wherein The upper part of the housing has two non-penetrating LED channels symmetrically arranged along the axial direction of the housing, and the LED channels are connected to the lens module channel; the LED channels extend from the rear end to the front end to a third length.
5. The endoscope tip of claim 4, wherein The upper part of the housing has two non-penetrating weight-reduction holes symmetrically arranged along the axial direction of the housing, and the weight-reduction holes are connected to the LED channel.
6. The endoscope tip of claim 5, wherein The weight-reducing hole extends from the rear end to the front end to a fourth length, the fourth length being less than the third length.
