Resectoscope

摘要

A resectoscope includes an electrode arrangement having at least one electrode and being connected to a contact at a proximal end region of the electrode arrangement; a retaining body mounted on the resectoscope that is movable in the direction of movement of the electrode arrangement and includes an electrode mounting for accommodating the end region of the electrode arrangement; and a cable with a plug body for fixing to the retaining body while making contact with the contacts. The retaining body has a plug receptacle for fixing the plug body by an insertion movement aligned at right angles to the direction of movement of the electrode arrangement. In the position which is reached at the end of the insertion movement, the plug body can be turned into an end position where it is blocked by the plug receptacle against a movement in the opposite direction to the insertion movement.

主权项

1. A retaining body of a resectoscope, the retaining body comprising:
a guide hole for mounting the retaining body on the resectoscope such that the retaining body can be moved in a direction along a longitudinal axis of the resectoscope; an electrode hole configured to accommodate a proximal end region of an electrode arrangement; and a plug receptacle comprising a chamber formed in the shape of a cylinder, the chamber being accessible from an exterior surface of the retaining body through a slot, the slot having a first side surface and a second side surface opposite to the first side surface that defines a slot width therebetween, and wherein the slot width is smaller than a diameter of the chamber, wherein the plug receptacle is configured to accommodate a plug body such that the plug body can be:
(i) inserted into the plug receptacle by an insertion movement of the plug body relative to the retaining body that is in a first direction at a right angle to the direction of movement of the retaining body;(ii) removed from the plug receptacle by a movement away from the retaining body that is opposite to the first direction; and(iii) rotated in a direction about the longitudinal axis of the resectoscope to reach an end position at which movement of the plug body away from the retaining body in a second direction at a right angle to the direction of movement of the retaining body is blocked by the retaining body, wherein the plug body can only be rotated to reach the end position once the plug body is contained within the retaining body at an end of the insertion movement.
