Abstract: A surgical instrument includes a female instrument part that defines a hollow volume in a coupling region and a male instrument part that forms a guide section in the coupling region. The guide section is configured to at least partially pass through the hollow volume. A pivoting element, which has an upper section, a center section, and a lower section, couples the female instrument part and the male instrument part to each other in such a way that the female instrument part and male instrument part can pivot relative to each other about an axis of rotation of the pivoting element. A lateral upper contact step is formed between the upper section and the center section of the pivoting element and a lateral lower contact step is formed between the lower section and the center section of the pivoting element.

Another exemplary medical apparatus may include a surgical tool; a feeder belt located at least partially within the surgical tool; staples affixed to and frangibly separable from the feeder belt; and a channel within the surgical tool that receives the feeder belt; where motion of the feeder belt through the channel bends at least one staple at least at one location, thereby work hardening that staple at each location at which it bends.

Abstract: A vertebral body replacement device includes a first member and a first footplate detachably connectable to the first member, a second member and a second footplate detachably connectable to the second member, and a central member detachably connectable to the first member. The first member is displaceable relative to the second member in response to rotation of the central member relative to the first member to adjust the length of the vertebral body replacement device. The first footplate includes a first surface oriented toward the first member, a second surface oriented away from the first member, and a sidewall extending between the first surface and the second surface. The first surface includes an alignment slot facing the first member. The alignment slot is open through the sidewall of the first footplate and configured to slidingly engage the first member to orient the first footplate relative to the first member.

Abstract: A spinal repositioning instrument includes a first coupling body for direct or indirect coupling to a pedicle screw, and a second coupling body for direct or indirect coupling to another pedicle screw. The spinal repositioning instrument can perform a first movement and a second movement independent from the first movement Under the first movement, the coupling bodies perform a scissor-like pivoting about a first axis. Under the second movement, the coupling bodies rotate in opposite directions about respective second axes. The second axes are relatively fixed under the second movement. The spinal repositioning instrument can also include a synchronising transmission such that the rotations of the coupling bodies under the second movement are symmetrical to each other.

Abstract: A filter cassette which is part of a filter system can be fastened to a sterile container lid. The sterile container lid serves to close a sterile container and to make a gas exchange possible between the container exterior and the container interior, without recontaminating the container material. In addition, the filter system fulfils a valve function. In order to center the filter cassette with respect to the sterile container lid, a first centering portion is provided on the filter cassette. The first centering portion interacts with a second centering portion on the sterile container wall section when the filter cassette is inserted into the sterile container lid.

Abstract: A surgical device for stabilizing tissue or positioning organs, or for positioning and holding surgical instruments and devices during a surgical intervention, includes a main body and a flexible arm. The flexible arm can be fastened to the main body, which can be brought into different positions and/or locations and which can be locked in a desired positioning by a tightening mechanism. The tightening mechanism can be tightened and/or released self-actingly and/or by an energy source. In a locked state of the flexible arm, the tightening mechanism has a retightening reserve, and the flexible arm can be automatically retightened in order to maintain its locked state, in particular by an introduction of energy from the energy source or self-actingly, by utilization of the retightening reserve. A retightening mechanism for use in the surgical device automatically retightens a flexible arm when in a locked state to maintain its locked state.

Abstract: A method of applying at least one coating of at least one electrically insulating polymer to an applicator for currents, especially HF currents in surgery, the coating is produced by electrophoretic deposition from a suspension of the polymer in at least one organic solvent, wherein the applicators thus coated are especially clamps, pairs of tweezers or pairs of scissors which are used in the bipolar application technique of HF surgery. Polymers used are especially thermoplastic polymers, such as thermoplastic fluoropolymers, and more particularly polychlorotrifluoroethylene (PCTFE) or ethylene chlorotrifluoroethylene (ECTFE).
