Abstract
Abstract A medical handling device, in particular for endoscopic applications, has a distally arranged medical instrument, a proximally arranged handle which has a grip part that can be gripped with the hand, and further a shaft part arranged between instrument and handle. It is proposed that the grip part gripped by a human hand can pivot relative to the shaft part about both the volar flexion axis and the dorsal flexion axis of the wrist, with no change occurring thereby in the position of the shaft part.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
96 words
Medical handling device, comprising a shaft, a medical instrument disposed at a distal end of said shaft, a handle disposed at a proximal end of said shaft, said handle is provided with a grip part, said grip part is pivotally mounted to said shaft, and said grip part can pivot about two axes perpendicular one to another, wherein said grip, once gripped by a human hand, can pivot about both, the volar flexion axis of the wrist and the dorsal flexion axis of the wrist, with no change occurring thereby in the position of the shaft.
Claim 2
Dependent Claim
96 words
Medical handling device, comprising a shaft, a medical instrument disposed at a distal end of said shaft, a handle disposed at a proximal end of said shaft, said handle is provided with a grip part, said grip part is pivotally mounted to said shaft, and said grip part can pivot about two axes perpendicular one to another, wherein said grip, once gripped by a human hand, can pivot about both, the volar flexion axis of the wrist and the dorsal flexion axis of the wrist, with no change occurring thereby in the position of the shaft.
Claim 3
Dependent Claim
30 words
Medical handling device according to claim 1, wherein said grip part is configured in that it can be grasped by the thumb and the inner surface of the human hand.
Claim 4
Dependent Claim
95 words
Medical handling device according to claim 1, wherein said grip part is carried by a first lever which is pivotally mounted in an articulated fashion on a second lever, said second lever is pivotally mounted in an articulated fashion on the shaft, and wherein a pivot axis of the one of the two levers coinciding approximately with the volar axis of the human hand grasping the grip part and a pivot axis of the other one of the two levers coinciding approximately with the dorsal flexion axis of the human hand grasping the grip part.
Claim 5
Dependent Claim
73 words
Medical handling device according to claim 3, wherein a bent bracket is provided at said proximal end of said shaft, said bent bracket projects laterally from the proximal end of said shaft, a bent end section of said bent bracket extends approximately parallel to a longitudinal axis of said shaft, and said second lever is attached in an articulated fashion at a proximal end of said bent end section of said bent bracket.
Claim 6
Dependent Claim
39 words
Medical handling device according to claim 4, wherein said second lever is configured as a laterally bent bracket at whose free end, approximately at the level of a longitudinal axis of the shaft, the first lever is pivotally mounted.
Claim 7
Dependent Claim
55 words
Medical handling device according claim 1, wherein said handle is in working engagement with the medical instrument arranged at the distal end of said shaft, said working engagement is in that the pivot movements of the grip part about the volar and/or the dorsal flexion axis are converted into corresponding pivot movements of the instrument.
Claim 8
Dependent Claim
27 words
Medical handling device according to claim 6, wherein said working engagement is accomplished via sheathed cables which transfer a pivot movement of the handle to the instrument.
Claim 9
Dependent Claim
26 words
Medical handling device according to claim 7, wherein said working engagement is accomplished via gimbals provided between said proximal end of said shaft and said handle.
Claim 10
Dependent Claim
39 words
Medical handling device according claim 1, wherein actuation means are provided for actuating the instrument, said actuating means comprises an actuation member arranged in that it can be actuated by the fingers of the hand gripping the grip part.
Claim 11
Dependent Claim
16 words
Medical handling device according to claim 1, wherein said shaft is configured as a tubular shaft.
Claim 12
Dependent Claim
20 words
Medical handling device according to claim 1, wherein said shaft can be inserted into a conduit of an endoscopic instrument.
Claim 13
Dependent Claim
23 words
Medical handling device according to claim 11, wherein said endoscopic instrument, into which the shaft part can be inserted, is a trocar sleeve.
Claim 14
Dependent Claim
