Abstract: A medical instrument includes a first instrument branch having a first bearing portion with a first support surface, and includes a second instrument branch having a second bearing portion with a second support surface. The first support surface bears flat against the second support surface such that the first support surface can pivot in a sliding fashion so that the first instrument branch is pivotable relative to the second instrument branch about a pivot axis. The first bearing portion and/or the second bearing portion has, in the region of the pivot axis, a shoulder portion or a shoulder element with an end face that includes the associated support surface. The shoulder portion or shoulder element is stepped outwardly relative to the associated bearing portion in the direction of the pivot axis so that the associated support surface is stepped outwardly relative to the associated bearing portion.

Abstract: A branch-crossed surgical instrument includes a female branch and a male branch, each branch having a terminal portion over the longitudinal extension thereof. The terminal portion of the female branch is passed through by a passage opening, which has a distal and a proximal longitudinal end surface, each having two outer edges and adjusted to receive the terminal portion of the male branch such that the two terminal portions form a plug-through closure in an assembly position of the instrument. The passage opening has a length, wherein the outer edges of the longitudinal end surfaces are exposed in all relative positions of the two branches, in particular in a completely closed position and/or in a completely opened position of the instrument, and not covered by the male branch.

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 medical instrument and method for producing a medical instrument with at least one instrument body part made from an instrument body part blank by forming. The at least one instrument body part has at least one deburring face formed by milling. The at least one deburring face includes one or more portions. Each portion extends perpendicularly to a machining plane. A normal to the machining plane defines a deburring longitudinal axis.

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.
