Abstract: A medical-technical instrument includes a first instrument branch, a second instrument branch, and a bearing element coupling the instrument branches in a superimposed closure. The branches contact each other in a closure portion in an operation pivot region via mutually facing contact surfaces so that the branches in the operation pivot region contact each other with their respective contact surfaces, and the branches are positionable in a cleaning position outside the operation pivot region. The bearing element is fixed at an end portion on the first instrument branch and has a head widening conically in a continuous or stepped manner. The head penetrates a continuously or stepped conical passage opening in the second instrument branch. The passage opening is an elongated hole, and the bearing element is rotatably positionable in the elongated hole and translationally fixedly received.

Abstract: A joining method for a medical device, in particular a surgical instrument or implant, with a shaft and an attachment to be secured on the shaft, the method having the following steps: heating the attachment or cooling the shaft, such that an internal diameter of an opening of the heated attachment is greater than an external diameter of the shaft, then placing the shaft into the opening of the attachment, and then cooling the attachment, so as to shrink the attachment onto the shaft in a manner substantially free of gaps, or heating the shaft, such that the shaft and the opening are connected by an interference fit. A corresponding medical device is produced by the joining method.

Abstract: A drill wire sleeve includes a tubular oblong sleeve having a length, an internal diameter and an external diameter. The drill wire sleeve has a first axial end cap and a second axial end cap. The first axial end cap and/or the second axial end cap is detachably fastenable without tools on the tubular oblong sleeve using a thread and detachably closes an insertion opening of the tubular oblong sleeve. The first axial end cap and/or the second axial end cap has a non-rotationally symmetrical outer cross section and the tubular oblong sleeve has a plurality of first passages in its lateral surface. The first passages are formed oblong and are inclined at an angle of 25° to 65° in relation to the longitudinal axis of the tubular oblong sleeve, preferably at an angle of 28° to 55°, and more preferably at an angle of 31° to 52°.

Abstract: A saw blade of a bone saw machine includes a distally arranged or configured row of saw teeth and a proximally arranged or configured coupling region for coupling the saw blade with an oscillating rotating tool receptacle of the bone saw machine. The saw blade is designed with two counter-rotating curvatures or bends approximately in the manner of an S shape.

Abstract: A surgical clip of branch-crossed design has two Z-shaped clip branches connected to each other at a proximal end of each of the clip branches by a spring-elastic connection piece. Each of the clip branches has a jaw part at a distal section with a gripping surface. In an assembled position of the clip, the clip branches cross and the gripping surfaces are opposite each other and are held in contact on one another by a closing force of the spring-elastic connection piece. At least one first clip branch has a groove in which the second clip branch is held and/or guided, at least in sections, such that a displacement of the clip branches in a transverse direction of the clip branches is prevented.

Abstract: A sandwich-type, steam-sterilizable universal label for sterile products packaging can be used both on soft packaging and hard packaging. The universal label has different adhesives with different adhesive properties which are covered in such a way that they can be exposed selectively individually and separately from each other for their respective adhesive actions.

Abstract: A method is used for determining a status of an encapsulation and/or a passivation layer of the encapsulation. The encapsulation forms a multi-layer system from multiple passivation layers arranged on top of one another and electrically contacted intermediate layers arranged between the passivation layers. The multi-layer system protects an implant surrounded by the encapsulation. In the method, an electrical measurement is carried out between a reference potential and at least one electrically contacted intermediate layer, and at least one current flowing between the reference potential and the at least one electrically contacted intermediate layer is detected. The at least one detected current is compared with at least one pre-determined threshold value. If the detected current falls below or exceeds the at least one threshold value, this indicates a functional state of a passivation layer adjacent to the at least one electrically contacted intermediate layer.

Abstract: A holding device for holding and supporting at least one medical instrument, more specifically a surgical handpiece. The holding device includes a central feedline, at least one line portion of which is connected to the end portion of a central feedline. At least one surgical handpiece can be coupled to the line portion. The holding device also includes a connector portion formed on another end portion of the central feedline. The connector portion can be coupled to a preliminary cleaning unit, more specifically a water/compressed air gun, and a cleaning unit, more specifically a filter unit connected to a rinsing line.

Abstract: A packaging, in particular sterile packaging, for a medical product, includes a receiving space for the medical product. A portion of the packaging facing the receiving space is made at least in part, preferably entirely, of a resorbable material.

Abstract: A receiving sleeve of a tool set includes a hollow body having an end face with an insertion opening for inserting a tool. The hollow body defines a longitudinal central axis and includes a plurality of inner clamping elements spaced apart in a circumferential direction. The clamping elements have punctiform or linear engagement sections at their free, radially inward protruding end portions. The engagement sections make force-fit and/or form-fit contact with the tool for holding the tool within the receiving sleeve at a radial distance from the hollow body. An inner side of the hollow body has circumferentially spaced rigid protrusions that extend axially in rib-like fashion. The inner clamping elements radially protrude further toward the longitudinal central axis of the hollow body than the rigid protrusions.

Abstract: A stent retractor/distractor includes a radially flexibly enlargeable, pipe-shaped sheath which is divided up in the circumferential direction in at least two sections, namely one stiffening section and one enlarging section with differing radial flexibilities, which are connected with each other in one piece of material. The stent retractor/distractor defined in that way is made on the whole by a laser or water jet cutting procedure, preferably from a pipe blank.

Abstract: A detector system for a medical motor system includes a multi-channel redundantly-configured detection device, which is accommodated in a hand-held control device that is adapted to control the medical motor system and which is positioned to detect the actuation of an actuation device of the hand-held control device. The multi-channel redundantly-configured detection device allows the plausibility of its output signals to be checked.
