Abstract
A transmission adapter for a medical instrument having a shaft, a transmission element that can move within the shaft and an operating device with a first part, which can be mechanically rigidly coupled with a proximal end of the shaft, and a second part, which can move with respect to the first part, includes a first coupling for releasable mechanical coupling with the second part of the operating device and a second coupling for releasable mechanical coupling with a proximal end of the transmission element.
Claims15
A transmission adapter for a medical instrument, having a shaft, a transmission element, which can move within the shaft, and an operating device with a first part, which can be mechanically rigidly coupled with a proximal end of the shaft, and a second part, which can move with respect to the first part, wherein the transmission adapter comprises:
- a first coupling for releasable mechanical coupling with the second part of the operating device;
- a second coupling for releasable mechanical coupling with a proximal end of the transmission element.
A shaft for a medical instrument, comprising:
- a proximal end for coupling with a first part of an operating device;
- a distal end for coupling with a tool;
- and,
- a transmission adapter, which is movable with respect to the shaft and which includes a first coupling for releasable mechanical coupling with a second pad of the operating device, and a second coupling for releasable mechanical coupling with a proximal end of a transmission element which can move within the shaft.
A shaft adapter, comprising:
- a proximal end for coupling with a first part of an operating device;
- a distal end for coupling with a proximal end of a shaft;
- a transmission adapter according to, which is movable with respect to the shaft adapter and which includes a first coupling for releasable mechanical coupling with a second part of the operating device, and a second coupling for releasable mechanical coupling with a proximal end of a transmission element which can move within the shaft.
A shaft for a medical instrument, comprising:
- a proximal end for coupling with a first part of an operating device;
- a distal end for coupling with a tool;
- and,
- a transmission adapter which is movable with respect to the shaft and includes:
- a first coupling for releasable mechanical coupling with a second part of the operating device:
- and
- a second coupling for releasable mechanical coupling with a proximal end of the transmission element:
- wherein the second coupling includes a movable gripper jaw for positive-locking or friction-locked holding of the proximal end of the transmission element;
- and,
- wherein the shaft further comprises:
- a lateral opening, such that the movable gripper jaw is mounted at least partly in the lateral opening, such that the movable gripper jaw is configured to be situated entirely within the contour of the shaft or shaft adapter when a proximal end of a transmission element is held positive-locked by the movable gripper jaw, and to extend above the contour of the shaft or shaft adapter upon the uncoupling of the transmission adapter from a proximal end of a transmission element.
A medical instrument, comprising:
- an operating device with a first part and a second part, which is movable with respect to the first part;
- a shaft with a proximal end, which can be mechanically coupled with the first part of the operating device, and a distal end;
- a transmission element, which is movable within the shaft, for transmitting at least either a force or torque between the second part of the operating device and the distal end of the shaft;
- and
- a transmission adapter which includes a first coupling for releasable mechanical coupling with the second part of the operating device, and a second coupling for releasable mechanical coupling with a proximal end of the transmission element.
