一种转接件、插入部及内窥镜

Abstract

本实用新型涉及医疗器械技术领域，并具体公开了一种转接件、插入部及内窥镜，插入部包括主动弯曲段和镜头座，主动弯曲段通过转接件与镜头座相连，转接件呈环状结构，转接件的远端侧壁设置有定位部，定位部与连接镜头座的线束的延伸路径相对应，定位部用于定位线束；在装配过程中，可先将镜头座内的摄像模组、光源与线束进行连接固定，然后将镜头座和线束一起弯折在主动弯曲段的侧面，此时可向线束的远端和近端施加一定的牵拉作用力使线束被定位部约束定位而保持在相对确定的位置，然后再将器械管等其他部件推送安装，能够避免线束与部件之间产生明显的遮挡干扰，能够显著提高插入部的装配效率，同时也能避免线束在插入部内出现绞绕打结的情况。

Claims

1. An adapter for use in the insertion portion of an endoscope, the insertion portion comprising an active bending section (100) and a lens mount (200), the active bending section (100) being connected to the lens mount (200) via the adapter (300), characterized in that, The adapter (300) has a ring-shaped structure. A positioning part (310) is provided on the distal sidewall of the adapter (300). The positioning part (310) corresponds to the extension path of the wire harness (400) connected to the lens mount (200). The positioning part (310) is used to position the wire harness (400) when the lens mount (200) and the wire harness (400) are bent on one side of the active bending section (100).

2. The adapter of claim 1, wherein, The positioning part (310) extends radially through the sidewall of the adapter (300). When the lens mount (200) and the wire harness (400) are bent on one side of the active bending section (100), the positioning part (310) is used to pass through the wire harness (400). The positioning part (310) is configured to position the wire harness (400) when the proximal and distal ends of the wire harness (400) are subjected to tensile forces. Alternatively, the positioning part (310) may be a positioning protrusion for winding around the wire harness (400) to pre-position the distal portion of the wire harness (400).

3. The adapter of claim 2, wherein, The active bending section (100) includes multiple snake-bone segments connected end to end. Two adjacent snake-bone segments are rotatably connected by a riveting part (111). The distribution position of the positioning part (310) in the circumferential direction of the adapter (300) corresponds to the distribution position of the riveting part (111) in the circumferential direction of the snake-bone segments.

4. The adapter of claim 3, wherein, Along the circumferential direction of the adapter (300), the width of the positioning part (310) is smaller than the width of the riveting part (111).

5. The adapter of claim 3, wherein, The bottom of the positioning part (310) is arc-shaped, and the adapter (300) has an arc transition at the inner and outer edges of the positioning part (310).

6. The adapter of any one of claims 1 to 5, wherein, The adapter (300) is also provided with a first auxiliary positioning hole (320), which is distributed near the positioning part (310) and extends radially through the adapter (300).

7. The adapter according to any one of claims 1 to 5, characterized in that, The adapter (300) is positioned and assembled with the lens mount (200) via the positioning part (310).

8. An insertion portion characterized by, Includes the adapter (300) as described in any one of claims 1 to 7.

9. The insert of claim 8, wherein, The active bending section (100) is provided with a second auxiliary positioning hole that radially penetrates the active bending section (100). The distribution position of the second auxiliary positioning hole in the circumferential direction of the active bending section (100) corresponds to the distribution position of the positioning part (310) in the circumferential direction of the adapter (300).

10. An endoscope characterized by comprising: Includes the insertion portion as described in claim 9.
