Abstract: The invention relates to a tubular medical instrument having a hollow shaft, a handle equipped with at least two gripping members and positioned on the proximal end of the shaft, and at least one push-pull rod that is mounted in the hollow shaft and has a tool consisting of at least two jaw members. For opening and closing at least one jaw member of the tool, said push-pull rod can be coupled with at last one rotatable gripping member of the handle, and the hollow shaft and handle can be releasably connected to one another by means of a coupling mechanism. To create a coupling mechanism that is simple to operate, it is proposed with the invention that the coupling mechanism should be configured as a combined clamping and snap-on device.
Abstract: The invention provides tweezers for microsurgery, in particular opthalmological surgery, the tweezers comprising a one-piece working part (1) of U-shape, with the free ends (2a, 3a) of each branch (2, 3) being shaped into a point, the part being derived from a flat blank of thickness (e) constituting the dimension perpendicular to the plane (P) in which the branches (2, 3) move, and elements for manipulating the working part together forming a handle for gripping the tweezers, wherein each element is in the form of an elongate body (4, 5) presenting a convex outside surface (4a, 5a) and a substantially plane surface (4b, 5b) having a longitudinal groove (6, 7) hollowed out therein to house one of the branches (2, 3) of the working part (1), the end of each handle element facing towards the points being provided with centering means (8a, 8b, 9a, 9b) co-operating with a complementary centering member of the corresponding end of the other element.
Abstract: Provided is a hand tool with a first handle portion, a first jaw portion connected to the first handle portion at a first jaw pivot located near a distal end of the first handle portion, a second handle portion connected to the first handle portion at a handle pivot, the handle pivot being located proximal of the first jaw pivot, a second jaw portion connected to the second handle portion at a second jaw pivot located near a distal end of the second handle portion, the handle pivot being located proximal of the second jaw pivot, and a first slider that is substantially elongate, has a length and a longitudinal axis along the length, the first slider extending between the first and second jaw portions and being slidably connected to the first jaw portion.
Abstract: The invention relates to a pinching device for surgical purposes comprising two parallel jaw elements having each a supporting part, one of which is provided with a pin at right angles thereto and the other having a sleeve mounted at right angles thereto and fitting around said pin.The pinching device according to the invention is characterized in that one supporting part is provided with a guide pin and the other has a bore receiving said pin located in the same plane as the first-mentioned pin and the sleeve.
