Marked trocars

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.

Trocar sleeve, trocar system and method of manufacturing a trocar sleeve

A trocar sleeve for minimally invasive surgery, having a first sleeve part, which has essentially the shape of a straight tubular piece with a longitudinal axis, and having a second sleeve part, which at least partly surrounds the first sleeve part in close contiguity and is movable during use with respect to the first sleeve part. The mobility of the second sleeve part in relation to the first sleeve part consists essentially only in rotatability of the second sleeve part around the first sleeve part, and in addition the first sleeve part and the second sleeve part each comprise on their distal axial ends a flange part that extends radially outward at an angle of less than 180 degrees from the respective sleeve part.

Trocar sleeve

Trocar

A trocar sleeve has a hollow shaft having a distal end and a proximal end, the shaft having a rectilinear shaft axis, an external thread rising from an outer surface of the shaft, wherein a first external thread having a shape of a helix has a height, measured from the outer surface up to a vertex of the helix, the height of the helix, seen along the rectilinear shaft axis from distal to proximal increases, and wherein a pitch of the helix, seen along the rectilinear shaft axis from distal to proximal decreases.

The present invention relates to an endoscopic instrument for retrograde biopsy, in particular synovial biopsy, comprising a head unit () having a distal tip portion () for penetrating tissue, a jaw part () with a tissue engaging formation () for removing the biopsy specimen, the jaw part () being pivotable from an idle position to an operating position in the direction of the distal tip portion () and back, wherein the tissue engaging formation () is essentially oriented away from the distal tip portion () in the operating position, as well as a first fluid channel area () open to the surrounding area in the region of the head unit (), wherein the first fluid channel area () is at least open to the surrounding area via at least one channel opening () provided in the jaw part (), when the jaw part () is in idle position.
