Abstract
An operating tool (1, 1a) for use in the operating room comprises a grip part (2, 2a) and a tool part (3, 3a) which is firmly connected to this grip part (2, 2a), with the connection of the grip part (2, 2a) and the tool part (3, 3a) being formed as a releasable connection.
Claims10
Operating tool for use in an operating room, comprising a grip part and a tool part which is firmly connected to the grip part, a reception at the distal end of the grip part into which the tool part is introduced, the reception comprising a sleeve which is manufactured of a hard, low-wear material, a connection of the grip part and the tool part being formed as a releasable snap connection, the snap connection having a snap collar which is firmly connected to the tool part and which is provided with resilient lamella which in each case have a projection in engagement with a corresponding projection at a distal end of the grip part, the lamella projecting out of the grip part in a distal direction and being provided outside the grip part with a member for pressing together the lamella to effect a releasing of the projections which are in engagement with one another.
An operating tool for use in an operating room, comprising a generally tubular grip part, a tool part including a sleeve made of a hard, low-wear material, and a releasable snap connection which firmly connects the grip part and the tool part, the snap connection including a snap collar firmly secured to the tool part and provided with a resilient lamella extending into the tubular grip part and having a first projection, the grip part having a second projection, the first and second projections snapping into engagement when the lamella extends into the grip part, a portion of the lamella projecting out of the grip part when the first and second projections are in engagement including a member positioned outside the grip part for moving the lamella relative to the grip part to disengage the first and second projections and permit a separation of the grip part and the tool parts.
An operating tool for use in an operating room comprising a grip part having a tubular opening and made of a hard, low-wear metal, a tool part including a portion insertable into the opening in the grip part for rotationally connecting the tool part and the grip part, and a snap connection for releasably securing the tool part to the grip part so that upon the release of the snap connection the tool part can be separated from the grip part, the snap connection comprising an axially extending resilient lamella having an inner end portion fixedly connected to the insertable portion of the tool part and a free outer end portion which projects out of the grip part when the tool part and the grip part are connected, the lamella being constructed of a resilient material and being arranged so that the free end portion of the lamella is resiliently biased away from the tool part, and first and second radially oriented projections pre-formed on the grip part and the free end portion of the lamella and arranged so that they engage each other and connect the tool part to the grip part when the insertable member is fully inserted in the opening, the free end portion of the lamella being manually engageable for moving the free end portion towards the tool part for disengaging the projections when the tool part is to be separated from the grip part.
