Abstract: A device is used for inserting at least one anchor piece into a hollow space of a living being, in order to fix a wall of the hollow space temporarily to a wall of the body by means of the at least one anchor piece. It is proposed that the device has two shaft-like elements which are axially movable relative to one another and by which the at least one anchor piece is held captive at its axially spaced apart opposite ends, and moreover has an actuating mechanism via which the at least one element can be moved in such a way that the anchor piece held by it is released.

Abstract: The invention relates to a holding and resting device for medical instruments having essentially cylindrical instrument bodies, in particular endoscopic instruments, with a base body that can be secured for instance to an operating table and an instrument input to be inserted into the base body and in which the instrument body can be secured by clamping. To create a holding and resting device for medical instruments having essentially cylindrical instrument bodies, which is of simple construction and can be activated quickly and safely, it is proposed with the invention that the instrument input includes a ring-shaped tension casing with at least two holder arms as well as a tension nut that works together with the tension casing.

Abstract: The balloon trepan is used in minimal invasive surgery in order to create or maintain the area required for an operation by dilation of tissue or dissection of layers of tissue. The connection between the balloon and the sleeve of the trepan must be easily and securely produced without enlarging the outer diameter of the balloon trepan. The balloon must be secured against slipping and must be able to resist pressure during inflation. The balloon surrounding the distal end of the trepan is pressed against a peripheral step formed on the sleeve of the trepan by a clamping element in order to fix it to the sleeve of the trepan. The clamping element is displaced by rotation of at least one part of the clamping element about a longitudinal axis of the sleeve of the trepan in a longitudinal direction in relation to the said sleeve.

Abstract: A medical punch with a hollow shaft, a tool point that is positioned on the distal end of the shaft and includes a rigid cutting part and a cutting part that can slide with respect to the rigid cutting part, and with a handle positioned on the proximal end of the shaft, such that the displaceable cutting part and the handle are operatively connected with one another by a push/pull device that is displaceably mounted in the hollow shaft and an anti-tilt mechanism is positioned on the tool point to stabilize the cutting parts in their axially parallel alignment to one another. The rigid cutting part includes a sleeve-shaped proximal portion that encloses the displaceable cutting part and a distal punch portion configured as a single unit with the sleeve-shaped portion and that the rigid cutting part should be detachably connected with the hollow shaft by a coupling mechanism formed on the sleeve-shaped portion.

Abstract: The invention relates to a surgical armrest, comprising an arm support and a carrying structure for the arm support. The carrying structure has a base and at least one pivot arm which at one end is articulated on the base so as to pivot about an at least approximately horizontal pivot axis and at the other end is connected to the arm support, such that a pivoting of the at least one pivot arm about the pivot axis causes a height adjustment of the arm support. The at least one pivot arm is assigned a control mechanism which alternately permits a fixing and pivoting of the at least one pivot arm in the downward direction and in the upward direction. The control mechanism has at least one bar which is movable, at least in its longitudinal direction, upon pivoting of the at least one pivot arm.

Abstract: A seal (10) is used for closing-off a proximal-side access port of an access instrument into a body. It has a cap (12) having a wall (14) covering the access port and a circumferential collar (16), which can be put over an edge of the access port. At least two approximately circular-segment-shaped openings are present in the wall (14), wherein a flexible dome sits on each opening and, on the proximal side, has, compared to the circular-segment-shaped openings, a smaller entry port (26, 28).

Abstract: A medical instrument for grasping surgical suture material, with a shaft on whose proximal end a handle is positioned consisting of at least two gripping members and on whose distal end a tool is positioned consisting of a rigid jaw member and a pivotable jaw member and where the pivotable jaw member can be pivoted with respect to the rigid jaw member for opening and closing with a moveably configured gripping member of the handle, for which purpose the pivotable jaw member and the moveable gripping member are in active connection with one another by means of an actuating element mounted in the shaft. To create a medical instrument that is both easy to operate and makes possible a safe grasping and guiding of the suture material, it is disclosed that in the rigid jaw member there should be configured an indentation that opens toward the pivotable jaw member and that can be covered, with the tool in closed position, only in the center area by the pivotable jaw member.

Abstract: The invention relates to a device for guiding surgical sewing material to a needle, having a shaft on whose distal end the needle can be secured and whose proximal end is configured as a gripping portion equipped with an open guide channel for the sewing material that is to be guided. To create a device that is of simple construction and ensures reliable transport of the sewing material to the needle, the invention proposes that the guide channel can be locked mechanically, at least in sections.

Abstract: A thread catcher for surgical sewing material consisting of a handle, a hollow shaft positioned on the distal side of the handle, and a catching device that is mounted so that it can be slid lengthwise within the hollow shaft by means of a drive element and whose distal end, which can slide out of the distal end of the hollow shaft, is configured as a catcher loop. To create a thread catcher for surgical sewing material that is simple to operate and ensures rapid and secure grasping of the surgical sewing material, it is proposed with the invention that the catcher loop should consist of at least three segments that re distally connected with one another.

Abstract: A medical punch having a hollow shaft, a punching tool that is mounted on the distal end of the hollow shaft and consists of a rigid cutting edge and a cutting edge that can slide with respect to the rigid cutting edge, and a handle mounted on the proximal end of the hollow shaft, where the displaceable cutting edge and the handle are operatively connected with one another by a push/pull device that is displaceably mounted in the hollow shaft and configured as a push/pull rod. To produce a medical punch that is of simple construction and can be thoroughly cleaned, it is proposed with the invention that the push/pull rod should be configured as a hollow shaft which can be inserted into the hollow shaft and extracted from the hollow shaft by the proximal end of the hollow shaft.

Abstract: The invention relates to a suturing set for medical use, comprising a handle piece, a needle, at least partly embodied as a hollow needle and which may be fixed to the handle and a transport device, arranged within the handle, which may be displaced between two end positions for the supply of suturing material to the needle, whereby the transport device comprises a gripping device, by means of which the supplied suturing material may be grasped in one end position of the transport device and then released in the other end position of the transport device. According to the invention, the transport of the suturing material to the needle may be achieved in a simple, secure and material-protective manner, whereby the introduced suturing material, on reaching an end position of the transport device, is gripped in a clamping manner by means of displacing the transport device and is only released again on reaching the other end position of the transport device.

Abstract: A medical instrument serves for spreading vertebral bodies apart and for operations in an area of a spinal column. A sleeve is provided and several spreadable elements protrude from a distal end of said sleeves. Said several spreadable elements are folded together to form a conical body, said conical body serves for inserting between adjacent vertebral bodies of a spinal column. A spreader is provided which can be driven into said conical body thereby spreading said several spreading elements, said spreading elements pushing away said two adjacent vertebral bodies.
