Abstract
Abstract A surgical manipulation instrument which is particularly suitable for minimal invasive surgery, comprising an extra-corporeal drive device and a partial intra-corporeal manipulator part. The drive device comprises several axially displaceable first actuation elements. The first actuation elements are detachably connected to axially displaceable second actuation elements, by a coupling device, the second actuation elements being used to actuate an end effector. The coupling device comprises two coupling elements, one of the coupling elements having undercut recesses in which the second coupling element engages.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
155 words
A surgical manipulation instrument, comprising: an extra-corporeal drive device comprising a plurality of axially displaceable first actuation elements, a partially intra-corporeal manipulator part comprising a plurality of axially displaceable second actuation elements for actuating an end effector, and a coupling device for detachable coupling of said first and second actuation elements pairs, said coupling device comprising a plurality of first coupling elements for each actuation elements pair, each with an undercut recess into which a second coupling element engages, wherein each actuation element pair is independently axially displaceable with respect to the other actuation elements pairs when the first and second actuation elements are coupled, wherein each of the plurality of the first coupling element is rotationally symmetric with respect to its longitudinal axis that coincides with a longitudinal axis of a corresponding first actuation element and second actuation element, wherein no orientation of said first and second coupling elements is required during coupling thereof.
Claim 2
Dependent Claim
155 words
A surgical manipulation instrument, comprising: an extra-corporeal drive device comprising a plurality of axially displaceable first actuation elements, a partially intra-corporeal manipulator part comprising a plurality of axially displaceable second actuation elements for actuating an end effector, and a coupling device for detachable coupling of said first and second actuation elements pairs, said coupling device comprising a plurality of first coupling elements for each actuation elements pair, each with an undercut recess into which a second coupling element engages, wherein each actuation element pair is independently axially displaceable with respect to the other actuation elements pairs when the first and second actuation elements are coupled, wherein each of the plurality of the first coupling element is rotationally symmetric with respect to its longitudinal axis that coincides with a longitudinal axis of a corresponding first actuation element and second actuation element, wherein no orientation of said first and second coupling elements is required during coupling thereof.
Claim 3
Dependent Claim
42 words
The surgical manipulation instrument of claim 1 , wherein the second coupling element comprises pivotable coupling arms having their free ends provided with a radially arranged projection, which engages into the undercut recess when the coupling device is in a closed state.
Claim 4
Dependent Claim
33 words
The surgical manipulation instrument of claim 2 , wherein the coupling arms are arranged on a circular ring and surround the first coupling element when the coupling device is in the closed state.
Claim 5
Dependent Claim
16 words
The surgical manipulation instrument of claim 1 , wherein the undercut recess is annular in shape.
Claim 6
Dependent Claim
28 words
The surgical manipulation instrument of claim 1 , wherein the first coupling element comprises a plurality of undercut recesses arranged one after the other in the axial direction.
Claim 7
Dependent Claim
23 words
The surgical manipulation instrument of claim 4 , wherein the diameter of the annularly shaped undercut recesses increases step-wise in the axial direction.
Claim 8
Dependent Claim
28 words
The surgical manipulation instrument of claim 1 , wherein the first and/or the second coupling element is/are rigidly connected with the first or the second actuation element, respectively.
Claim 9
Dependent Claim
32 words
The surgical manipulation instrument of claim 1 , further comprising a fixing element for holding the coupling elements in a closed position in order to prevent the coupling device from being opened.
Claim 10
Dependent Claim
31 words
The surgical manipulation instrument of claim 8 , wherein the fixing element at least partly surrounds the coupling elements in the closed position, the fixing element comprising an axially displaceable sleeve.
Claim 11
Dependent Claim
30 words
The surgical manipulation instrument of claim 1 , wherein the second coupling element comprises holding elements, adapted to be displaced radially into the undercut recess, for closing the coupling device.
Claim 12
Dependent Claim
38 words
The surgical manipulation instrument of claim 1 , wherein the first coupling element comprises an axial bore into which the second coupling element may be inserted, the undercut recess being provided on an inner side of the bore.
Claim 13
Dependent Claim
36 words
The surgical manipulation instrument of claim 10 , wherein, in the closed position, an axially displaceable fixing element presses the holding elements radially outward and comprises a recess into which the holding elements slide for opening.
