The invention relates to a tubular medical instrument having a hollow shaft, a handle positioned on the proximal end of the shaft and equipped with at least two gripping members, and at least one push-pull rod that is positioned in the hollow shaft and has on its distal end a tool consisting of at least two jaw members, wherein for opening and closing at least one jaw member of the tool, the push-pull rod can be coupled with at least one rotatable gripping member of the handle and wherein the push-pull rod and the handle can be detachably connected to one another by a coupling mechanism that is configured as at least one clamping device comprising at least one clamping claw characterized in that the at least one clamping claw can rotate in a guide track mounted between a closed position and an open installation position. To create a coupling mechanism that is easy to handle, it is proposed according to the invention that the at least one clamping claw is mounted in a guide track so that it can rotate between a closed clamping position and an open installation position.

Tubular medical instrument

The invention relates to a tubular medical instrument having a hollow shaft, a handle equipped with at least two gripping members and positioned on the proximal end of the shaft, and at least one push-pull rod that is mounted in the hollow shaft and has a tool consisting of at least two jaw members. For opening and closing at least one jaw member of the tool, said push-pull rod can be coupled with at last one rotatable gripping member of the handle, and the hollow shaft and handle can be releasably connected to one another by means of a coupling mechanism. To create a coupling mechanism that is simple to operate, it is proposed with the invention that the coupling mechanism should be configured as a combined clamping and snap-on device.

The invention relates to a tubular medical instrument having a hollow shaft, a handle positioned on the proximal end of the shaft, and at least one tool actuation element that is positioned in the hollow shaft and has on its distal end a tool, wherein the tool actuation element can be coupled with at least one actuation mechanism of the handle to actuate the tool and wherein the tool actuation element and the hollow shaft can be detachably connected to one another by a coupling mechanism. To create a coupling mechanism that is essentially free of any play and is simple to operate, it is proposed with the invention that the stopping of the coupling mechanism between the tool actuation element and the hollow shaft should be dependent on the position of the tool.
