Abstract: A trocar sleeve comprises a flexible hollow shaft comprising a distal end and a proximal end, and a handling head that is formed at the proximal end of the hollow shaft. The trocar sleeve is manufactured from an elastomer material. The hollow shaft comprises an inner contour that is adapted to an outer contour of a trocar mandrel in such a way that the trocar sleeve and the trocar mandrel are arranged to be coupled to one another while generating a defined preload to stabilize the trocar sleeve. A trocar system comprises a trocar sleeve and a trocar mandrel that is arranged to be inserted in the trocar sleeve, while generating a defined preloading in the trocar sleeve. A method of manufacturing a trocar sleeve involves integrally forming a hollow shaft and a handling head in a common mold by molding.

Abstract: A component (14) for a medical instrument includes a shaft (15), a transmission device (16), which is movable in the shaft (15), for transmitting a force from a manipulation device (18) coupled to the proximal end of the component (14) to a tool (13) at the distal end of the component (14), an abutment surface (86) on the shaft (15), and an abutment surface (36) on the transmission device (16). The abutment surface (86) of the shaft (15) and the abutment surface (36) of the transmission device (16) are arranged such that a mechanical contact between the abutment surface (36) of the transmission device (16) and the abutment surface (86) of the shaft (15) limits a movement of the transmission device (16) relative to the shaft (15) in the proximal direction.
Abstract: A suture anchor includes a tubular anchor body made of suture material, the tubular anchor body having a partially open distal tip and a bore extending through the tubular anchor body to a proximal end of the tubular anchor body and a suture woven from the distal tip and extending through the bore and exiting through the proximal end, the suture forming a suture loop outside of the distal tip. The tubular anchor body is configured such pulling an end of the suture at the proximal end causes the tubular anchor body to collapse.
