Endoscope head
The invention relates to an endoscope head comprising an endoscope head body in which at least one working channel is formed, wherein a pivot member actuatable from the proximal side is provided on the distal side of the endoscope head body, wherein an Albarran lever capable of being pivoted is provided at the distal end portion of the working channel.
1. An endoscope head comprising an endoscope head body in which at least one working channel is formed, wherein, on a distal side of the endoscope head body, a pivot member actuatable from a proximal side by a control wire is provided, wherein an Albarran lever capable of being pivoted is provided on a distal working channel end portion of the endoscope head body, wherein
the Albarran lever is arranged at the pivot member such that it is displaceable relative to the pivot member,
wherein the Albarran lever is arranged at the pivot member such that the Albarran lever is slidably removable relative to the pivot member in a distal direction from the endoscope head body, and
wherein the endoscope head further comprises a cap which is distally slid onto the endoscope head body and which is integrated with the Albarran lever such that the Albarran lever pivots relative to the cap.
2. The endoscope head according to claim 1 , wherein
the Albarran lever is detachably mountable to and demountable from the pivot member without the use of tools.
3. The endoscope head according to claim 1 , wherein
the Albarran lever is detachably mountable to and demountable from the pivot member with the use of tools.
4. The endoscope head according to claim 1 , wherein
the cap comprises an opening which corresponds to a working channel end opening, and
the Albarran lever is relatively displaceable at the pivot member, independently from the cap.
5. The endoscope head according to claim 1 , wherein
the cap comprises an opening which corresponds to a working channel end opening.
6. The endoscope head according to claim 1 , wherein
the proximally actuatable pivot member, together with a supporting member supporting an axis of the proximally actuatable pivot member, forms a common assembly detachable from and mountable to the endoscope head body, wherein in an operational state, the common assembly is surrounded by the cap.
7. The endoscope head according to claim 1 , wherein
the proximally actuatable pivot member, together with a supporting member supporting an axis of the proximally actuatable pivot member, is housed in the endoscope head body.
8. The endoscope head according to claim 1 , wherein
the proximally actuatable pivot member comprises a force receiving member into which the control wire is fittable.
9. The endoscope head according to claim 8 , wherein
the endoscope head body comprises a control wire channel through which the control wire fitted into the force receiving member extends.
10. The endoscope head according to claim 1 , wherein
a sealing member is arranged between the proximally actuatable pivot member and the Albarran lever.
11. The endoscope head according to claim 1 , wherein
the Albarran lever is formed as a shovel whose distal end can be pivoted about a pivot axis of the pivot member up to a location which, when viewed in a longitudinal direction of the endoscope head body, is provided proximally relative to the pivot axis of the pivot member.
12. The endoscope head according to claim 1 , wherein
the Albarran lever is formed as a shovel whose inner surface forms an extension portion of the working channel, wherein the shovel inner surface is curved such that it forms a tangent from a straight working channel end portion of the endoscope head body towards the curved shovel inner surface which forms the working channel extension portion of the Albarran lever.
13. The endoscope head according to claim 1 , wherein the pivot member actuatable from the proximal side by the control wire, is installed in the endoscope head body.
14. An endoscope head comprising an endoscope head body in which at least one working channel is formed, wherein, on a distal side of the endoscope head body, a pivot member actuatable from a proximal side by a control wire is provided, wherein an Albarran lever capable of being pivoted is provided on a distal working channel end portion of the endoscope head body,
wherein the Albarran lever is arranged at the pivot member such that it is displaceable relative to the pivot member,
wherein the Albarran lever is arranged at the pivot member such that the Albarran lever is slidably removable relative to the pivot member in a distal direction from the endoscope head body, and
wherein the endoscope head further comprises a cap which is distally slid onto the endoscope head body and which is integrated with the Albarran lever such that the Albarran lever pivots relative to the cap.
15. The endoscope head according to claim 14 , wherein the cap comprising an opening which corresponds to a working channel end opening.
