Holding and resting device for medical instruments having essentially cylindrical instrumental bodies
View Patent ↗The invention relates to a holding and resting device for medical instruments having essentially cylindrical instrument bodies, in particular endoscopic instruments, with a base body that can be secured for instance to an operating table and an instrument input to be inserted into the base body and in which the instrument body can be secured by clamping. To create a holding and resting device for medical instruments having essentially cylindrical instrument bodies, which is of simple construction and can be activated quickly and safely, it is proposed with the invention that the instrument input includes a ring-shaped tension casing with at least two holder arms as well as a tension nut that works together with the tension casing.
1. A holding and resting device for medical instruments having cylindrical instrument bodies comprising a base body secured to an operating table and an instrument receptacle that is inserted into the base body and in which the instrument body is secured by clamping, distinguished in that the instrument receptacle comprises a ring-shaped clamping sleeve which includes at least two holder arms and further comprises a tightening nut working together with the clamping sleeve, wherein the instrument body is released and secured in the instrument receptacle by said tightening nut and in that a ring-shaped holder element comprises an elastically reshapable material that is inserted into the clamping sleeve for receiving the instrument body, wherein an inner surface of the elastic holder element facing the inserted instrument body is configured as toothed even in an unclamped position with each tooth being in linear contact with the instrument body with respect to the direction of insertion in the unclamped position and is in contact with the instrument body in the clamping position only in some areas, and wherein not more than one half of the total inner surface of the elastic holder element is in contact with the instrument body when in the unclamped and clamped positions.
2. A holding and resting device according to claim 1 , distinguished in that the holder arms of the clamping sleeve can be re-shaped radially by using clamping elements configured on the tightening nut.
3. A holding and resting device according to claim 2 , distinguished in that the clamping sleeve has four holder arms uniformly positioned around the circumference of the ring-shaped clamping sleeve, which can be reshaped by four cogs configured on the tightening nut that serve as clamping elements.
