Abstract:
A medical instrument has a first instrument part and second instrument part. The first and second instrument parts are mounted to one another, pivotable about a pivot axis, and coupled to one another with a connecting element. The connecting element has a head accommodated in a head recess on the first instrument part. The head recess is open pointing from the first instrument part in a direction away from the second instrument part. The head has a circumferential, self-contained first annular face pointing away from the longitudinal axis. The head recess has a circumferential, self-contained second annular face pointing toward the longitudinal axis. The first and second annular faces are separated by an annular gap. A sealing element is arranged in the annular gap, in contact with the first and second annular faces. A medical instrument set includes medical instruments differing in shape, type, and/or size.
Abstract:
An assembly method, a screwdriving tool and a screw kit for screwing a screw into an internal thread of a medical instrument to connect two branches of the instrument to each other so that the branches are pivotable relative to each other. The method includes: impressing a punch geometry into a screw head of the screw by applying an axial compressive force to the screw by the screwdriving tool, and rotating the screwdriving tool relative to the instrument about a screw longitudinal axis to transmit a torque in a positively locking manner from the screwdriving tool to the screw via the impressed punch geometry and to screw the screw into the internal thread.
Abstract:
A surgical instrument includes a female branch defining in a coupling area a hollow volume including inwardly facing inner coupling surfaces and including a male branch which can be pivoted relative to the female branch at least partly inside the hollow volume about a pivot axis, the male branch defining in the coupling area a guide portion having outwardly facing outer coupling surfaces in which outer coupling recesses are arranged, wherein on the inner coupling surfaces, inner coupling recesses are arranged which extend relative to a longitudinal axis of the surgical instrument in a direction other than that of the outer coupling recesses.
Abstract:
A surgical cutting instrument for transapical aortic valve resection includes a cutting unit arranged on the distal end of a tool shaft and at least one mechanical cutting element for making a circular incision. The at least one cutting element can be adapted, in particular continuously adapted to different aortic diameters by means of a radially movable actuating mechanism.

Abstract:
A surgical hand grip for a surgical tubular shaft instrument is provided. The hand grip includes a coupling device for coupling to a tubular shaft tool having a tubular shaft and a force transmission element movable back and forth relative thereto. The coupling device has a coupling element for coupling to the force transmission element and a connecting element for connecting to the tubular shaft. A gripping device is connected to the coupling element and is transferable from a non-actuating disposition into at least one actuating disposition and vice versa thereby changing the mutual relative spacing between the coupling element and the connecting element. The hand grip has a guiding device with a guiding body for guiding the coupling element during the transfer from the non-actuating position into the at least one actuating position along a grip axis independently of the disposition of the gripping device during the transfer.
Abstract:
An adapter device for detachably fastening instruments and equipment to a side rail of an operating table includes a clamping device by means of which the adapter device can be clamped to the side rail of the operating table, a longitudinal profile onto which the instruments and equipment can be detachably fastened, and a joint having at least one pivot axis formed between the clamping device and the longitudinal profile so that the longitudinal profile is pivotable relative to the clamping device about the pivot axis of the joint.
Abstract:
The present application discloses a telescopic retractor holder comprising a telescopic rod with an inner tube, an outer tube and a locking mechanism as well as a retractor rod. Said retractor rod has at its one end a retractor mounting, which is adapted for releasably gripping a retractor, and at its other end is fastened to the telescopic rod by means of a jointed connection. The telescopic rod can be supported on an operating table and has an actuating mechanism, by which the locking mechanism can be transferred from a first position, in which the inner tube and the outer tube of the telescopic rod are held immovably in relation to one another, into a second position, in which the inner tube and the outer tube of the telescopic rod are movable in relation to one another in the longitudinal direction of the tubes.
Abstract:
A medical instrument includes two handle elements that are pivotable relative to one another and a spring unit having two spring end portions. Each spring end portion is connected to one of the handle elements such that, when at least one of the handle elements is pivoted out of a starting position, the spring unit can pivot the handle element back into the starting position. The spring unit provides a substantially constant spring force when the handle elements are pivoted, and includes a first spring leg and a second spring leg. A platform-like projection is formed on at least one of the spring end portions and/or on at least one of the handle elements to connect the spring end portion to the associated handle element, such that the at least one spring end portion is raised relative to the associated handle element, with a gap formed between them.
