Abstract

Abstract A holding instrument for implantation and explantation of prosthesis can be fastened to the proximal end of a prosthesis by means of a lining (11). The hollow cylindrical or conical lining (11) which grasps the end of the prosthesis is mounted so that it can slide axially in an approximately cylindrical receiver part (13) with a conical guide surface (12). The end of the prosthesis is gripped by the lining and drawn into the receiver part by means of a force transducer (15, 19). A frictional force which depends on the draw-in distance is exerted on the end (24) of the prosthesis by the conical guide surface. This holding instrument allows prostheses (25) made from composite fibrous material to be handled without the risk of breakage.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 194 words
A device for holding prostheses for implantation of the prosthesis, comprising a substantially hollow cylindrical chuck for gripping one end (24) of the prosthesis, the said chuck, for the purposes of clamping or for releasing the gripping action, being axially displaceably mounted inside a substantially cylindrical receiving part (13) having a conical guide surface (12), the hollow cylindrical chuck (11) having an at least partly conical outer surface (12'), characterised in that the hollow cylindrical chuck (11) is made of plastics at least on the inside and is conical in shape and is formed with as large a contact surface as possible in order to ensure, between the prosthesis and the chuck, a frictional connection also suitable for explantation, and in that the chuck has a slightly conical outer surface (12') with a conicity of 0.1° - 5° and is guided within the conical guide surface (12) of the receiving part (13), the angle (b) of the said conical guide surface (12) being equal to the angle (b) of the conical outer surface (12') of the chuck, with the result that the entire circumferential surface of the chuck is uniformly acted upon by pressure.
Claim 2
Dependent Claim 18 words
A device according to claim 1 or 2, characterised in that the chuck (11) is made of plastics.
Claim 3
Independent Claim 32 words
A device according to either one of the preceding claims, characterised in that the chuck (11) is axially displaceable by means of a spindle (15, 19) mounted inside the receiving part (13).
Claim 4
Independent Claim 39 words
A device according to any one of the preceding claims, characterised in that an attachment (30) for transmitting impulses is associated with the device (10) and can be connected to the device (10) obliquely to the axis (31') thereof.
