The branches are each provided over a part of their length with a tooth-shaped back profile and a longitudinal cutting blade on their outer back sides lying opposite the gripping surfaces.

Abstract: The invention relates to a device for the picture-providing and spectroscopic diagnosis of tissue with the alternative or combined use of three diagnosis methods, specifically a mode A for the picture-providing white light diagnosis, a mode B for the picture-providing fluorescence diagnosis and a mode C for the fluorescence-spectroscopic diagnosis. The device comprises a first light means whose light as a beam bundle via a beam path is coupled into an optical fiber leading to an endoscope and a second illumination means whose light as a beam bundle via a second beam path may be coupled into the same fiber-optic. In the first beam path there is arranged an element widening the bundle opening, for the light beam bundle entering into the fiber-optic and in the second beam path there is arranged an element limiting the bundle opening, for the light beam bundle entering into the fiber-optic.

Abstract: A hysteroscope for carrying out endoscopic operations in the uterus by way of an auxiliary instrument, consists of an inner shank and an outer shank surrounding the inner shank whilst forming a longitudinal channel, of a first fitting for supplying rinsing fluid to be supplied through the inner shank into the uterus and of a second fitting for removing rinsing fluid from the uterus via the longitudinal channel. Furthermore there are provided a third fitting on which the auxiliary instrument is introducable into the hysteroscope and is further distally movable through a working channel, and deflection means with which the distal end region of the auxiliary instrument is elastically laterally deflectable.

Abstract: The invention relates to a spreading laryngoscope with two spatulas able to be moved apart, wherein on at least on of the two spatulas on each longitudinal side there is formed in each case one projecting tab which, proceeding from the longitudinal side of the one spatula, extends to the other spatula and is rigidly connoted to the spatula.

Abstract: The invention relates to a coding system for the identification of tools in medical apparatus as well as to a corresponding method, with which successive code elements (16; 20) are attached on an outer side of a tool, and a stationary read means is arranged on a stationary part of an apparatus in the vicinity of the tool for detecting the successive code elements (16; 20) on movement of the tool (2) relative to the stationary part.

Abstract: A solid-state video camera is equipped with pixel addition logic such that, if the measured object brightness falls below a certain threshold value, a brightening of the image is effected without increasing the noise component accepting a loss in real-time representation. The pixel addition by way of the pixel addition logic is coupled to the gain control of the camera in a manner such that, in each case, the gain control compensates for jumps in brightness which arise by way of the pixel addition and creates for the user a flowing transition without noticeable jumps in brightness.

Abstract: In the region of a distal end at its circumference the waveguide is formed transparent to the radiation which impinges onto the surface of the waveguide at suitable angles, and in the region of the distal end in the inside of the waveguide there are arranged scatter elements which scatter radiation transmitted by the waveguide in the direction of the distal end in a direction with a proximally directed component which exits the circumference of the waveguide. Alternatively, radiation entering into the waveguide at the circumference of the waveguide in a direction with a distally directed component is transmitted by the waveguide in the direction of the proximal end, as well as to its use and to a method for its manufacture.

Abstract: A suction valve for an instrument includes a valve insert secured in a valve housing. A first sleeve connects the interior of the valve housing to a first suction channel of the instrument; and a sealing membrane seals a first portion of the interior of the valve housing from the valve insert. The sealing membrane is fixed in the valve housing by the valve insert that includes a valve plunger for opening and closing the sealing membrane by movement in a first direction.

Abstract: In the inside of an outer shank there are formed a supply channel and a discharge channel which extend parallel to the outer shank. The suction channel has a larger cross section than the supply channel.

Abstract: The invention relates to a guide rod for tube shank instruments to be introduced into a body cavity which is characterised by at least two telescopic rod parts, whose ends which neighbor given the largest possible rod length, are releasably lockable with a positive or non-positive fit and whose extension movement is limited by an abutment.

Abstract: The invention relates to a locking device, especially for anvil shears, ensuring closure of the shear free from any light gap and irrespective of manufacturing tolerances and wear. A pivoting tumbler (24) fitted with a cam surface (34) and interacting with a corresponding cam surface (32) of the other limb (14) of the shear is actuated by the force of an opening spring (20) into closed position (10). The arrangement operates in such a way that the cam surfaces interact in a self-locking manner when continuously pivoted in the closing area and the tumbler may be moved to an end position when the limbs of the shear are progressively closed thus ensuring a final closing position. The cam surfaces (34) of the tumbler interacting with a cam surface (32) of a catch groove (28) can have a larger configuration in the direction of closure. Due to technical manufacturing reasons, an arched cam surface may also be provided, which is eccentrically located in relation to the pivoting axis of the tumbler.

The shutter has, in a central area, a radially uniform transmission function averaged over the circumferential angle. The radial transmission function first drops off toward zero in a radial transition area which is a continuation of the central area and which has a quantity n of cutouts which extend toward the radial outside and are spaced apart from one another at equal angles 360°/n in the circumferential direction. The quantity n of cutouts has the value 5, 6 or 7.
