Abstract
Abstract A relatively flat, disk-shaped gripping device for a medical instrument is moved axially with respect to the instrument by exerting pressure by the hand, or in a circumferential or rotary direction by the finger or thumb. The gripping device is fixed in non-rotary manner on the distal side of the shaft of a medical instrument, allowing a surgeon to easily place the instrument into any random rotary position by finger actuation, without adjusting the basic position of the hand.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
175 words
An instrument grip for medical forceps, said instrument grip comprising: two gripping members operable by one hand, an outer instrument sleeve and an inner instrument shaft movable relative to each other and each including a gripping member rigidly connected to the proximal ends of said outer instrument sleeve and said inner instrument shaft, respectively, said gripping members being spring-tensioned with respect to each other to ensure a maximum spacing of said gripping members in an operative position, said gripping members being constructed as gripping disks, said gripping disk of said instrument shaft, n operation, lies in the palm of the user while said gripping disk of said instrument sleeve is gripped by the fingers of the user, said gripping disk of said instrument shaft being freely rotatable by a finger over 360° relative to said outer instrument sleeve, and said gripping disks having a minimum axial spacing between radial edge regions so that a radial insertion of a finger between said gripping disks is possible during a relative reciprocal axial movement of said gripping members.
Claim 2
Dependent Claim
175 words
An instrument grip for medical forceps, said instrument grip comprising: two gripping members operable by one hand, an outer instrument sleeve and an inner instrument shaft movable relative to each other and each including a gripping member rigidly connected to the proximal ends of said outer instrument sleeve and said inner instrument shaft, respectively, said gripping members being spring-tensioned with respect to each other to ensure a maximum spacing of said gripping members in an operative position, said gripping members being constructed as gripping disks, said gripping disk of said instrument shaft, n operation, lies in the palm of the user while said gripping disk of said instrument sleeve is gripped by the fingers of the user, said gripping disk of said instrument shaft being freely rotatable by a finger over 360° relative to said outer instrument sleeve, and said gripping disks having a minimum axial spacing between radial edge regions so that a radial insertion of a finger between said gripping disks is possible during a relative reciprocal axial movement of said gripping members.
