Abstract
Abstract The instrument has a working insert which may be inserted into a coupling housing sitting on the proximal side on an instrument shank and is releasably connectable to said housing and which includes a seal, carried by a carrier, which has at least one elastic socket for the sealed leading-through of auxiliary instruments and which seals a first axial passage formed in the carrier with respect to the coupling housing. The seal consists of a base body which is located in a holder and which with each socket forms a one-piece component of elastic material, and the holder includes an arrangement for the releasable connection to the carrier.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
105 words
A medical instrument, comprising: an instrument shank; a coupling housing sitting on a proximal side of the instrument shank; and a working insert releasably connected to said housing, the insert including a carrier and a seal carried by the carrier, the insert having at least one elastic socket for sealed leading-through of auxiliary instruments and seals a first axial passage formed in the carrier with respect to the coupling housing, the seal having a holder and a base body located in the holder, the seal and the socket forming a one-piece component of elastic material, the holder having means for releasably connecting to the carrier.
Claim 2
Dependent Claim
105 words
A medical instrument, comprising: an instrument shank; a coupling housing sitting on a proximal side of the instrument shank; and a working insert releasably connected to said housing, the insert including a carrier and a seal carried by the carrier, the insert having at least one elastic socket for sealed leading-through of auxiliary instruments and seals a first axial passage formed in the carrier with respect to the coupling housing, the seal having a holder and a base body located in the holder, the seal and the socket forming a one-piece component of elastic material, the holder having means for releasably connecting to the carrier.
Claim 3
Dependent Claim
62 words
A medical instrument according to claim 1 , wherein the first passage in the carrier has a contour that matches with a contour of a distal-side attachment on the base body of the seal, the socket being arranged to project proximally from the base body so as to open in a passage of the base body in a region of the attachment.
Claim 4
Dependent Claim
25 words
A medical instrument according to claim 2 , wherein the contour of the first passage and of the attachment on the base body are crescent-shaped.
Claim 5
Dependent Claim
43 words
A medical instrument according to claim 3 , wherein the holder is bow-shaped and comprises an opening corresponding to the crescent-shaped contour of the attachment of the base body so that the holder encompasses the base body in the region of the attachment.
Claim 6
Dependent Claim
65 words
A medical instrument according to claim 4 , wherein the carrier has fastening pegs that project proximally from an end-face side of the carrier and taper conically towards the distal side, the ends of the bow-shaped holder in each case comprise a recess so that the end is fork-shaped and releasably fastenable with a positive and non-positive fit on the carrier on the fastening pegs.
Claim 7
Dependent Claim
35 words
A medical instrument according to claim 5 , wherein a second axial passage is provided in the carrier at a distance from the first passage so that the second passage lies free of the seal.
Claim 8
Dependent Claim

A medical instrument according to claim 2 , wherein the holder is substantially crescent-shaped and lies on an annular shoulder formed on the distal-side attachment of the base body.
Claim 10
Dependent Claim
46 words
A medical instrument according to claim 8 , wherein a proximal-side surface of the annular shoulder comprises a crescent-shaped depression that accommodates the holder with a positive fit and forms a reinforcement for a sealing lip which represents a contact surface between the seal the carrier.
Claim 11
Dependent Claim
19 words
A medical instrument according to claim 1 , wherein the instrument shank is releasably fastened on the coupling housing.
Claim 12
Dependent Claim
47 words
A medical instrument according to claim 1 , and further comprising a handle connected to the coupling housing so as to have a free end that projects from the coupling housing, and fastening means provided at the free end of the handle for fastening on a mounting.
Claim 13
Dependent Claim
17 words
A medical instrument according to claim 1 , wherein three sockets are provided on the base body.
Claim 14
Dependent Claim
