Endoscope combined deflection control and lock

摘要

An endoscope including a shaft having a deflectable distal end; a main section at a proximal end of the shaft, where the main section forms a handle of the endoscope; and a deflection control connected to the distal end. The deflection control includes a combined lock and deflection control member at the main section comprising a control lever pivotably connected to the main section at a pivot and extending away from the pivot in a general cantilever fashion, and a lock lever pivotably connected to the control lever. A first end of the lock lever is configured to contact the main section. A second end of the lock lever is configured to be pressed inward on the control lever towards the main section to pivot the first end out of contact with the main section.

1. An endoscope comprising:
a shaft having a deflectable distal end; a main section at a proximal end of the shaft, where the main section forms a handle of the endoscope; and a deflection control connected to the distal end, wherein the deflection control comprises a combined lock and deflection control member at the main section comprising a control lever pivotably connected to the main section at a pivot and extending away from the pivot in a general cantilever fashion, and a lock lever pivotably connected to the control lever, where a first end of the lock lever is configured to contact the main section and where a second end of the lock lever is configured to be pressed inward on the control lever towards the main section to pivot the first end out of contact with the main section, wherein the first end of the lock lever comprises a projection adapted to contact a lock section on the main section when the lock lever is at a locked position, and wherein the projection is disengaged from the lock section on the main section when the lock lever is pivoted on the control lever to an unlocked position.
