Disclosed is a medical instrument having at least one surgical element, such as a knife or the like disposed at the distal end thereof, a motor disposed at the proximal end thereof, and a shaft which connects the shaft of the motor to the shaft of the surgical instrument in such a manner that the surgical element is rotated. According to the invention either the motor is detachably connected to said shaft of the said surgical element in an as such known manner so that a bend can be inserted betw...

An instrument for insertion into the body which includes a flexible image-transmitting element, a flexible light guide, and in some embodiments, a channel for intubation gas, which instrument contains a head for receiving a connection for the image-transmitting element. Because of their flexibility, they can variably be curved. To enable the doctor readily to follow the curvature during the insertion of the elements, an eyepiece is connected to the head by a joint or hinge. This enables the doct...

Disclosed are medical tongs, in particular, for use in endoscopic surgery, having a handpiece, provided with a stationary and a movable handle, an external tube, which is connected to the stationary handle, and inside the external tube a moveably guided draw-rod, which actuates at least one of the two tong elements of the tong jaws and which is connected to the movable handle. The present invention is distinguished by a bayonet element, which can be inserted into a bayonet insert inside the exte...

A dilator for surgical use having a ball on the end of a thin stiff stem. A plurality of telescoping tubes are adapted to be slid along the stem and atop one another so as successively to enlarge the path opened by the dilator. An endoscope shaft can be slid over the set of tubes so as to occupy the region they have enlarged, and to permit them and the probe to be withdrawn so an endoscopic procedure can be performed.

A concave mirror is mounted on a head band and is associated with a light source for lighting an area to be inspected for medical purposes. A support for the mirror has a viewing path in which is incorporated a prism which is constructed to have a main viewing path for use by the person wearing the head band and to have a branch path for viewing by a second person. A viewing tube and eyepiece is secured to the support for viewing the branch path of the prism, and such tube is of sufficient lengt...

The distal insulated end of an endoscope shaft has an inner layer made from a material having a higher heat resistance than the material in the insulated end. Such heat resistant layer preferably contains a ceramic material and is constructed as an inner ring which is inserted and cemented into a correspondingly sized inner groove in the insulating material.

The invention relates to a medical instrument with an endoscope, in which a wire loop, gripping arms or the like are arranged in displaceable manner in the longitudinal direction of the endoscope, as well as with a telescopic periscope which is displaceable together with the wire loop electrode or the like and in which between a ring connected to the telescopic periscope and an axially displaceable slide, which, is connected to the wire loop or the like, are arranged first and second levers inte...

An endoscope having an edoscope shaft, a periscope, optics removably secured to the endoscope shaft and separable from the endoscope shaft and an instrument channel having an apertured cap through which treatment instruments are introduced into the instrument channel under visual control via the optics. The endoscope shaft has a hollow interior, a substantially kidney-shaped cross-section with a substantially semicircular upper surface portion for partial extenral reception of a catheter in the ...

An endoscope which includes an endoscope shaft and rotatable about the shaft axis, an eyepiece secured to and rotatable with the endoscope shaft about the axis of the endoscope shaft, a gear secured to and rotatable with the eyepiece and the endoscope shaft, an endoscope grip secured to the said gear, the gear positioned relative to the endoscope grip to permit manual holding of the grip and rotation of the gear with the same hand and a light guide for providing light to the endoscope shaft.

The invention relates to a contact endoscope for medical purposes, whose front lens or distal cover plate for the objective is brought into contact with the place to be observed. The invention enables a sample to be taken from the observed place even during observation, or at least immediately afterwards, without having to pull the contact endoscope out of the body. To this end a strip-blade of small wall thickness can be moved in a slideway at a small distance in front of the front lens. In thi...
