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: An endoscopic instrument includes a shank (2) having at least one guide channel (4, 4?) for a laser probe (8), and a flexible narrowing provided in a section of the guide channel (4) connecting to its distal end. The flexible narrowing allows a clear diameter of the guide channel (4, 4?) to be changed in at least one direction.

Abstract: An endoscope is provided with a processing tool (24) arranged at its distal end. The processing tool can be moved by a mobile hollow shaft (12) extending in the longitudinal direction (X) of the endoscope. An endoscope optic (14) is arranged inside the mobile hollow shaft (12).

Abstract: A medical forceps is provided with a tubular outer shank, on whose distal end there is formed a forceps jaw with two jaw parts. The two jaw parts are each rotatably mounted on the outer shank at two sides opposite one another. A tubular inner shank for actuating the jaw parts is displaceably arranged in the inside of the outer shank in its longitudinal direction. The inner shank is coupled to the two jaw parts for their actuation via two lever systems. Each of the lever systems is linked to the two jaw parts, one lever system on each of the two opposite sides.

Abstract: A spreading laryngoscope is provided with two spatulas able to be moved apart, wherein on at least on of the two spatulas on each longitudinal side there is formed at least one projecting tab. The at least one tab on each side proceeds from the longitudinal side of the one spatula, extends to the other spatula, and is rigidly connected to the one spatula from which it proceeds.

Abstract: An endoscope has an optics housing provided at a proximal end, with an outer shank releasably connected to the optics housing, and with an inner shank which is arranged inside and parallel to the outer shank and is releasably connected to the optics housing. A corresponding endoscope set and a set of endoscope shanks are also provided.

Abstract: A syringe for connection to a fluid container containing fluid to be discharged comprises a syringe barrel with a plunger moving therein, and a discharge outlet, through which fluid contained in the fluid container is dischargeable by actuation of the plunger, said syringe barrel being connected with the fluid container port and the discharge outlet via a fluid channel system, and a valve mechanism being provided in the fluid channel system, allowing the syringe barrel to be filled with fluid from the fluid container and to then discharge said fluid through the discharge outlet, wherein the valve mechanism comprises a valve member which is movable between first and second positions, said valve member, in said first position, allowing fluid flow from the fluid container to the syringe barrel and simultaneously blocking fluid flow from or to the discharge outlet and, in said second position, allowing fluid flow from the syringe barrel to the discharge outlet while simultaneously blocking fluid flow from or to t

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 focussing and focal length adjusting device for an optical lens system in the camera head of an endoscope. This device includes a focussing device which has several piezoelectric bending actuators attached along and symmetrically to the optical axis of the focussing lens. The piezoelectric bending actuators are via in each case one joint member connected to a sleeve encompassing the focussing lens in a manner such that with voltage impingement bending movements carried out by the bending actuators are converted into a linear focussing movement for the focussing lens. Furthermore a zoom drive adjusting the focal length of a zoom lens system includes a stepper motor whose stepped rotation via a grooved roller and a pin linearly moved by the helical groove of this roller is converted into a linear movement of a zoom lens sleeve for the focal length adjustment.

Abstract: The target apparatus for positioning a drilling tool with respect to a drilling channel to be created in a bone consists of a target hook and a guide arm which is releasably connected to this and on which there is arranged a receiver for the drilling tool, and a guide path in the form of a laterally through-going open groove for the guide arm. The guide arm may be displaced and fixed in the guide path. A simple assembly and disassembly of the apparatus is achieved in that the guide arm on the side of the apparatus is applied into the guide path through the groove opening and reversely, by lifting away out of the groove, may be separated from the target hook.

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: The instrument serves for the application in particular of bone grafts in the space between two vertebrae and includes a shank, a handle, and a holder for the implant, which forms the distal instrument part. The holder is pivotably mounted relative to the shank and can be fixed in any respective position which is reached by pivoting.

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: A technoscope for examining surfaces in confined spaces includes a shank on whose distal end a pivotable arm with a measuring device is arranged, which may be pivoted from a first position in which the arm extends in the longitudinal direction of the shank into a second position in which the arm extends bent at an angle to the longitudinal axis of the shank.

Abstract: A surgical instrument has a tool located at the distal instrument end, a stationary first grip part at the proximal instrument end, a second grip part adjustable in an axially guided manner in the form of a reel, and an actuation element for the tool. The actuation element in connection with the second grip part is axially adjustable on adjustment of the second grip part. For improving the handling of the instrument, it is envisaged that, by way of a lever system linked onto the second grip part and a stationary part of the instrument, the adjustment path of the second grip part is geared down and the force exerted onto the second grip part is transmittable, geared up, to the actuation element.
