Patent DE-3644490-A1 (DE)
Title: Bone biopsy set
Inventor: VORWERK DIERK DR
IPC: A61B10/02
Filed: 1986-12-24
Abstract: Conventional devices for withdrawal of samples from bone possess a boring head which forms the front end of a rotating biopsy needle. The boring head must rotatingly cut through the soft tissue in front of the bone, and injuries may result if the tool is not guided accurately. Once the boring head has reached the bone it may jam due to thermal expansion. The biopsy set according to the invention has an external needle (10) which is displaced by a trocar arranged therein without rotation through the soft tissue into the bone (30). After removal of the trocar the hollow drilling needle (17) is pushed into the external needle (10), and the bone (30) is drilled with the annular boring head (19). The wall thickness of the boring head (19) increases toward the front end, so that the annular drilling channel is wider than the boring head which can thus be easily pulled out. The biopsy set is also suitable for removal of soft tissue samples located behind hard bone layers, in that an internal needle with a trocar is advanced through the drilled channel after the hollow drilling needle. <IMAGE>

Patent DE-3707186-A1 (DE)
Inventor: DAVID HEINRICH
IPC: G01N1/00
Filed: 1987-03-06
Abstract: An apparatus for metering, measuring, or dosing flowing media. A distribution slide valve is disposed in a housing between an inlet and an outlet. A metering piston is disposed in a chamber of the housing and divides the chamber into a first and a second metering chamber. The two end positions of the slide valve alternately connect the metering chambers to the inlet or outlet. Transfer passages are disposed on the periphery of the slide valve for selective connection of connecting passages to the inlet, the outlet, and the metering chambers. A transverse connection of the slide valve connects a central control channel thereof to the inlet via a first one of the transfer passages in either of the end positions of the slide valve. Each end of the latter is associated with a hydraulic control chamber into which the control channel opens. Relief passages connect the control chambers to the outlet. A piston rod connected to the metering piston extends axially displaceably through the larger diameter control channel, with the slide valve being axially movable relative to the piston rod. Sealing elements are disposed on the piston rod, with the control channel being adapted to be alternately sealed off relative to one or the other of the control chambers via these sealing elements.
