US 6962590 B2Abstract
The invention relates to a medical instrument with a handle on which at least one gripping part, in particular a finger ring, is secured by a connecting clamp in a removable manner and is mounted in rotatable fashion on one handle part, and the connecting clamp consists of a shaft configured on one of the components that are to be connected to one another and of a sheath configured on the other component and where the outer diameter of the shaft, forming an undercut in the area of the free end of the shaft, exceeds the core diameter of the shaft and the inner diameter of the sheath correspondingly has an area forming an undercut and serving to receive the free end of the shaft, with a larger inner diameter, and an area extending in the direction of the sheath opening with a lesser inner diameter. In order to provide a removable placement of the gripping part on the handle, which ensures a secure attachment on the handle, the shaft in the area of the free end having the greater outer diameter is provided with an outer thread and an inner thread is configured in the sheath in the area of the smallest inner diameter.
This application is a continuation of pending International Patent Application No. PCT/EP01/07580 filed Jul. 3, 2001, which designates the United States and claims priority of pending German Application No. 10035722, filed Jul. 22, 2000.
Additional characteristics and advantages of the invention can be seen from the following description of the related illustration, in which an embodiment of the medical instrument according to the inventive design is presented by way of example. The illustration is as follows:
The medical instrument depicted schematically in FIG. 1 is a passive resectoscope. Resectoscopes are used in certain surgical interventions in order to remove portions of tissue under endoscopic observation. The illustrated resectoscope consists essentially of a hollow shaft 1, an endoscope 2 placed in the shaft 1, and a handle 3 mounted at the proximal end of the shaft 1, by means of which a tool, not shown, can be guided parallel to the shaft 1. As can be seen from FIG. 1, the handle 3 consists of a rigid handle part 4 connected to the shaft 1 and a handle part 4 that can be displaced in relation to the rigid handle part 4 to actuate the tool. In the illustrated embodiment the movable handle part 5 is secured on one side to the endoscope 2 by means of a lever mechanism made up of several levers 6 connected flexibly to one another. In passive resectoscopes, this design is exactly reversed. In that case the movable handle part 5 is situated on the distal side. For precise guidance of the movable handle part 5 and thus of the tool, the movable handle part 5 is equipped with a gripping part 7, in particular a finger ring, by means of which the surgeon can guide the tool as desired and sensitively while monitoring it with an endoscope. To ensure the greatest possible freedom of movement for the surgeon, the gripping part 7 is secured on a handle part 4, 5 so that it can rotate freely around the longitudinal axis, that is, proximally on the movable handle part 5 in the case of a passive resectoscope and distally on the rigid handle part 4 for an active resectoscope.
