Endoscope
Provided is an endoscope with a handle and an endoscope shaft connected to the handle, which has a bendable section and a rigid section, adjoining it, with a support extending in the longitudinal direction of the endoscope shaft, wherein the bendable section has a flexible outer tube the end of which facing the rigid section rests on the support, wherein a fixing sleeve is connected to the end section and covers the end of the outer tube facing the rigid section such that said end is clamped for fixing between the fixing sleeve and the support.
1. An endoscope comprising:
a handle;
an endoscope shaft having proximal and distal ends, the proximal end connected to the handle, the endoscope shaft comprising:
a bendable section, including a flexible outer tube having a distal end portion, an inside surface and an outside surface;
a rigid section adjoining the distal end portion of the flexible outer tube, the rigid section including a support extending in the longitudinal direction of the endoscope shaft towards the proximal end of the endoscope shaft,
wherein the inside surface of the distal end portion of the flexible outer tube contacts the support; and
a fixing sleeve, connected to the rigid section and extending over the outside surface of the of the distal end portion of the flexible outer tube such that the distal end portion of the flexible outer tube is secured between the fixing sleeve and the support,
wherein the fixing sleeve includes a first fixing region having a gradually tapered converging internal diameter, and wherein the support includes a second fixing region having a diverging portion wherein an outside diameter of the support increases gradually in the longitudinal direction towards the distal end of the shaft from a first diameter to a maximum diameter and a converging portion adjoining the diverging portion wherein the outside diameter of the support gradually decreases in the longitudinal direction towards the distal end of the shaft from the maximum diameter to a second diameter.
2. The endoscope according to claim 1 , wherein the fixing sleeve is screwably mounted on the rigid section in the longitudinal direction of the endoscope shaft.
3. The endoscope according to claim 1 , wherein the first fixing region contacts the outer surface of the flexible outer tube opposite the location where the second fixing region contacts the inside surface of the flexible outer tube.
4. The endoscope according to claim 1 , wherein the first fixing region of the fixing sleeve lies opposite the diverging portion of the support.
5. The endoscope according to claim 1 , further comprising a housing sleeve fastened to the rigid section, the housing sleeve including a support area forming the support.
6. The endoscope according to claim 5 , wherein the housing sleeve includes a fastening area to which the fixing sleeve is directly connected.
7. The endoscope according to claim 1 , wherein the rigid section comprises the distal end portion of the endoscope shaft.
8. The endoscope according to claim 7 , wherein the endoscope shaft further comprises a rigid main part disposed between the handle and the bendable section, the rigid main part connected to the bendable section, wherein the rigid main part comprises a second support extending along a longitudinal direction of the endoscope shaft, on which a proximal end of the flexible outer tube rests, and wherein a second fixing sleeve is connected to the rigid main part and covers the proximal end of the flexible outer tube, such that said proximal end is secured between the second fixing sleeve and the second support.
9. The endoscope according to claim 1 , wherein the first diameter and the second diameter are the same.
