Abstract: A method for producing a surgical instrument for grasping and/or holding and/or guiding a needle includes: a) producing a first arm part and a second arm part, each having a distal holding jaw with a recess and a solder deposit region; b) inserting hard metal inserts into the recesses in the distal holding jaws; c) joining the first arm part and the second arm part so that the first arm part and the second arm part are pivotable relative to one another at a joint; d) filling the solder deposit regions with solder; and e) soldering the hard metal inserts in the distal holding jaws using the solder.

Abstract: A medical instrument, for example an impact instrument, and a method for producing a medical instrument. The medical instrument includes a proximal end and a distal end. A handle and a striking face facing in a proximal direction are arranged or formed on the proximal end. A tool instrument is arranged or formed on the distal end. An instrument shaft of the instrument extends from the proximal end to the tool element. The handle is configured in the form of a hollow handle.

Abstract: A medical instrument and a semi-finished instrument. The semi-finished instrument includes an instrument body part blank for forming an instrument body part of the medical instrument. The instrument body part blank is made of a metal, in particular an instrument steel. The semi-finished instrument also includes a distal end region and a recess on the distal end region for accommodating a hard metal element. The recess has an abutment face for the hard metal element. The instrument body part blank includes a solder chamber for accommodating solder. The solder chamber is fluidically connected to the recess.

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 process for the surface treatment and/or production of a metal or alloy product including the steps of: a) dulling of a surface of the metal or alloy product and b) electrochemical treatment of the dulled surface of the metal or alloy product, and a metal or alloy product which produced or able to be produced by the process.

Abstract: In the case of a method according to the invention for connecting at least two components of an endoscope, at least one brazing preform, which contains a high-temperature brazing solder, is introduced into at least one brazing solder reservoir of at least one of the components, the at least two components are held in relation to one another in such a way that at least one brazing gap that is in capillary connection with the at least one brazing solder reservoir is formed between joining regions of the at least two components that are assigned to one another, and the arrangement comprising the at least two components and the at least one brazing preform is heated to a brazing temperature of the high-temperature brazing solder. The invention also relates to a component of an endoscope and to an endoscope.

Abstract: An endoscope having an elongate shaft and a system tube, which extends inside the shaft and in which an image carrier is arranged, the system tube is held in an axial direction of the shaft by means of at least one resilient latching element, and a method for producing such an endoscope and to a latching element for such an endoscope.
