A yarn limiting disc device for use in winding a yarn package on a yarn package carrier of a textile machine includes a substantially planar, annular disc body adapted to have extend therethrough a beam of a yarn package carrier under which a yarn package is to be wound. A plurality of hollow reinforcing ribs extend generally radially along one side of the disc body.

A bayonet coupling (10) is used for detachable joining of two tubular-shaft instruments or instrument parts. A bayonet sleeve (12) (female part), having a bayonet guide (14), is provided on the one instrument or instrument part, and a bayonet insert (52) (male part) is provided on the other instrument or instrument part. An interlock system serves to lock the bayonet coupling (10) in the closed state. It is proposed that the interlock system have an interlock piece (28), displaceable along the bayonet sleeve (12), which comes directly into inhibiting engagement with the bayonet insert (52) inserted into the bayonet sleeve (12), in the insert's terminal position, and inhibits the bayonet insert (52) from rotating; and which can be moved away from the bayonet insert (52) in order to release the interlock system (FIG. 1).

A tubular shaft instrument, in particular a trocar, has an instrument channel which can be closed off by a flap valve. An actuation element serves to open the flap valve against the force of a closing spring. It is proposed that the actuation element be configured as an element which at least partly surrounds the instrument channel and can rotate about the instrument channel axis, and which is equipped with a circumferential cam bevel, rising in the direction of the instrument channel axis, on which a control section of the flap valve rests, so that a rotation of the rotatable element effects opening or closing of the flap valve.

Disclosed is a device for carrying out manipulations in the human body, in particular in the uterus. The device includes a hook element provided with at least one hook which is connected via a rod, which is guided in a shaft, to a grip end provided at a proximal end of the device in such a manner that the hook can be pivoted in and out. The invention is distinguished by a glide element which is guided in a sliding manner on the shaft in the longitudinal direction thereof and is provided at its distal end with an approximately bell-shaped expansion.

A flexible endoscope has at least one outer protective coat, one protective mesh and elements arranged in the distal region, which are connected via a series of connecting lines for data and/or energy transmission to the connection element arranged at the opposite end. The mesh includes a plurality of conductive lines which are electrically insulated from each other. The connecting lines are included among the conducting lines of the mesh.

A medical instrument for irrigation and/or suction has an instrument body in which at least one flow channel is present for the passage of a fluid, at least one shut-off member for alternately shutting off the at least one flow channel, and an actuating member for actuating the shut-off member. The at least one shut-off member is a ball which, in a closure position, lies sealingly on a sealing edge of the flow channel so that it closes off the internal cross section of the flow channel, the ball being movable, between the closure position for closing the flow channel and a release position for freeing the flow channel, substantially in a direction transverse to the longitudinal direction of the flow channel, and the actuating member for moving the ball between the closure position and the release position being movable in a direction transverse to the flow channel.

The invention relates to a medical instrument for removing tissue comprising a tool at its distal end which can be supplied with high frequency power. The instrument includes an HF power terminal and an HF power supply line extending frown a proximal end region of the instrument to its distal end. In the present instrument, the HF power supply is configured as a drive shaft for rotary drive of the tool. Furthermore, contact means are provided electrically connected to the HF power terminal, which electrically contact the drive shaft.

An insertion assembly is provided for controlling insertion of an instrument assembly into an endoscope shaft. Instrument locking elements are provided having a first position preventing movement of the instrument assembly relative to the shaft and having a second position allowing movement of the instrument assembly relative to the shaft. Actuator locking elements are provided having a first position allowing bending of the instrument assembly and having a second position preventing bending of the instrument assembly. Movement of the instrument locking elements into the first position moves the actuator locking elements into the first position. Further, movement of the instrument locking elements into the second position moves the actuator locking elements into the second position.

The invention relates to a medical instrument with a hollow instrument canal that is configured inside a housing and can be closed by means of at least one valve body and rotated into open position by means of an instrument inserted into the instrument canal. The at least one valve body is configured as a flap consisting of an essentially non-bendable material mounted on the housing so that it can be rotated by means of an elastic, bendable connecting element configured as a wire spring in such a way that the valve body is pre-tensioned in the closed direction. A medical instrument with a valve body of simple construction, which insulates reliably, is distinguished according to the invention in that the connecting element on the one hand is secured on the housing and on the other hand carries the valve body, so that the connecting element can be secured in a ring groove configured in the housing.
