Embodiment Construction

[0032] according to Figure 1a , 1b, 2 and 8, a medical / surgical instrument system typically includes a medical instrument 1 with an internal hydraulic / pneumatic motor or with an external / separate motor unit 2 with hydraulic / pneumatic design and a medical instrument or motor unit for pneumatic or hydraulic drive medical handle 4. The handle 4 comprises at its distal end a preferably female clutch member 6 for a corresponding preferably male clutch member 8 on one side of the instrument 1 or upstream motor unit 2 mechanical and pneumatic / hydraulic coupling; and an internally manually operable valve mechanism or regulating / control valve mechanism 10 for the medical device 1 coupled to the handle or the upstream motor unit 2 of the medical device 1 Pressurize selectively. In particular, the valve mechanism 10 includes a safety device or safety function for preventing pressurization if the medical device 1 or its motor unit 2 is unlocked and / or decoupled.

Abstract

The invention discloses a medical handle with a pneumatic safety coupling. The present invention relates in summary to a medical handle for pneumatically or hydraulically operated medical instruments or motor units, with a preferably female coupling part for the mechanical and pneumatic / hydraulic coupling of a corresponding, preferably male coupling part, and a manually activatable valve mechanism for selectively applying pressure to a coupled medical instrument or to the motor unit thereof, which is provided with a safety mechanism for preventing pressure being applied in the case of an uncoupled medical instrument or motor unit thereof. According to the invention, provision is made that the coupling part provided on the handle interacts with the valve mechanism in such a way that the latter is automatically opened during or by the mechanical coupling procedure and / or is enabled for manual opening, whereas the valve mechanism is closed and / or the enablement is cancelled in the uncoupled state.

Description

technical field [0001] The invention relates to a handle of a medical device comprising an integrated pneumatic / hydraulic safety clutch, in particular to a handle of a medical device according to the preamble of claim 1 . Background technique Background of the invention [0002] Medical instruments, in particular surgical instruments, relate in particular to those instruments which are equipped or can be equipped with motor-driven tools such as milling cutters, drills, screwdrivers and the like. For example the drive of the rotary or lifting movement of the tool can be carried out hydraulically or pneumatically by an electric motor. Especially in the latter case, the instrument is connected to a source of compressed air, by means of a source of compressed air, such as a turbine within the instrument or like a separate motor unit which is selectively pressurized and possibly controlled by compressed air, the rotation of the turbine being then passed through the gear Units ...
