Abstract: The invention relates to a method and device for imaging a cyclically moving organ of a human or animal body, with a device supported such that it can be rotated at an angular velocity around the body recording images of the organ from different angle positions, with the angular velocity being modulated with a reference signal representing the movement phase of the organ. During the rest phase of the organ images of the organ are recorded at nominal angular speed. In the movement phase of the organ the device is slowed down, turned back and accelerated again such that on entry into the next rest phase the device records images for the next angle range at nominal angular velocity without major angle gaps in respect of the previous angle range, to generate the most complete data record possible.

Abstract: The invention relates to a disassemblable cock with which a plug rotatable in the cock housing is releasably latched with the housing. The plug can be moved by tension or pressure from a working position into an intermediate position in which the sealing surfaces of the plug and of the cock housing are located out of bearing yet the plug remains connected to the housing (FIG. 1).

Abstract: The medical instrument is equipped with a handle and has a shank for supplying and removing rinsing fluid into or out of a hollow cavity inside the body. There are tubings which can be releasably inserted onto connection pieces connected to the shank and which can be fixed on the connection pieces. The handle is formed as a two-part housing, wherein for opening and closing the housing a first housing part is adjustable relative to a second housing part so that with an opened housing the tubings can be pushed or pulled from then freely situated connection pieces and with a closed housing the tubing ends located on the connection pieces are fixed onto the connection pieces with a friction fit by way of the first housing part.

Abstract: The invention relates to a device for connecting a fiber optic cable to the fiber optic connection of an endoscope. An end section of the optical fiber is mounted as a bundle of fibers in a housing part and a coupling part is provided for the fastening with a positive fit of this housing part to the fiber optic connection on the endoscope side. To ensure that the optical fiber ends always come into contact with one another free of play and to improve the cleaning access, the coupling part is arranged on the housing part axially displaceable against a spring force in the direction of the fiber optic connection on the endoscope side.

Abstract: The operating rod is provided for a medical instrument, in particular for an endoscopic instrument and consists of at least two rod parts transmitting tension and/or compression forces and which at their ends facing one another, are connected to one another with a positive fit at least in the direction of their longitudinal axis. In order to achieve a high force transmission with a slimline construction, the face ends facing one another, of the rod parts are arranged essentially in a plane lying obliquely to the longitudinal axis of the rod and are provided with toothed profiles engaging into one another with a positive fit.

Abstract: A control device serves the steering of the distal end of an endoscope, this being by operating control cables running to the distal end of the endoscope by way of a handle. The control device is accomodated by a control housing at the proximal end of the endoscope and has an adjusting and braking mechanism for adjusting and fixing the distal endoscope end as well as further as a handle, a lever which is to be operable with one hand and which serves as a combined braking and control member. This lever, from a first position, can be rotated about an axis wherein it acts upon the control cables via a shaft connected to the handle as well as via an insert rotatably mounted in the housing and connected to the shaft, and in a second position together with the insert can be fixed against rotation by way of a friction fit via a brake effective between the control housing and the insert.

Abstract: An bendable endoscope is disclosed which comprises tube sections. Neighbouring tube sections are completely materially separated from one another via a circumferential separating gap and are only connected to one another with a positive fit. By providing a corresponding number of tube sections, a flexible shank or a flexible shaft may be formed. The manufacture may be effected by laser cutting from a rigid tube.

Abstract: An endoscopic instrument is disclosed which comprises a shank with a bendable region. The bendability is achieved by almost complete circumferential transverse recesses which form segments bendable to each other. To increase the robustness of the shank, the segments, at their free ends, are provided with guides which engage a neighbouring recess and are adapted to the contour of the shank. Furthermore in the lateral regions of the shank there are incorporated positive locking elements, which prevent the overloading of the shank on over-extension.

Abstract: A surgical instrument such as a forceps having a handle at its proximal end, a pair of jaws at its distal end for gripping an object, and a connecting member for transmitting user-applied force from the handle to the pair of jaws. The connecting member includes a force transmitting and limiting member for transmitting the closure force imparted by the jaws upon the object to a predetermined value. The force transmitting and limiting member is preferably made of a material that is superelastic (i.e. reversibly deformable such that it returns to its original physical shape or form after the material has been deformed substantially) and is comprised of a rod, a spring or a portion of a scissors-shaped forceps. The extent of relative movement of the handle grips is limited by a stop to prevent the superelastic material from undergoing excessive deformation.

Abstract: The endoscopic instrument has a long, stretched out shaft (5) and at least one rod-shaped lens (6) arranged therein. The rod lens (6) is provided on its peripheral surfaces (10) with a coating that increases the breaking strength. The coating may be, for example, polyimide, amorphous carbon, or silicon-oxide carbide. To increase adhesion of the coating the rod lens may be pretreated with caustic on its peripheral surfaces.

Abstract: The flexible shaft suitable for technical and surgical endoscopes consists at least partly of circular braiding of webs interwoven with one another. A particularly stable and torsion-resistant shaft also having low wall thickness is produced in that weaving of the webs formed by the flat wires is single-braided, and in that the circular braiding is machined by hammering, particularly in the region of the crisscrosses of the flat wires.

Abstract: An endoscope with a flexible shaft, which consists of individual sub-assemblies releasably connected to each other. The proximal end of a flexible shaft is joined to a connecting portion and the distal end of the shaft can be steered into different positions by adjustment of an operating wire by means of an adjusting lever. The connecting portion can be coupled releasably to the distal end of the handle portion, at the proximal end of which an eyepiece portion is arranged. A hand-operated control means for the operating wire is provided in the handle portion, wherein the proximal end of the operating wire is clamped by a receiver in the control means. The receiver can be opened by operation of the adjusting lever for the purpose of releasing the above mentioned wire end, by moving the adjusting lever forwards of a neutral position. Moving the adjusting lever backwards from the neutral position effects longitudinal movement of the operating wire for controlling movement of the flexible shaft.

Abstract: The endoscope for introduction into a hollow organ of a living thing makes it possible for the hollow organ to be pulled against a more solid outer structure and to fix it thereto for the duration of the treatment. The endoscope is therefore provided with a retaining device, which can be used in the outer shaft of the endoscope and is guided therein, and has a plurality of hook elements, on the distal end of which hooks are formed by pushing out from the distal end of the outer shaft as a result of spreading, and with a stop disc which can be adjusted on the outer shaft. Spreading of the hook element ends can be controlled optically. After spreading the hook element ends, the endoscope is drawn back until it rests on the hollow organ in order to fix the hollow organ and secured in this position by means of the stop disc.

Abstract: An endoscope instrument shaft is provided with a bendable distal end piece, the position of which relative to the instrument shaft can be altered by means of at least one tension wire which is actuable proximally of the endoscope and is guided through a guide tube which is fixed at both ends. That side of the end piece, which side has the larger radius of curvature when the end piece is bent is constructed as a return spring and the side of the end piece having the smaller radius of curvature when the end piece is bent is pliable to facilitate bending of the end piece.

Abstract: A tubular channel usable in endoscopy for flexible auxiliary instruments such as forceps, electrodes and the like to be passed through, in which structuring of the outer wall face by means of a plurality of radial grooves is employed to obtain high flexibility on the one hand and on the other hand a cross-sectional strength which improves its resistance to collapse when suction is applied and also to internal pressure.
