Abstract: A device for the irrigation and suction drainage of body cavities, especially in surgical laparoscopy, hysteroscopy, uroscopy, or arthroscopy. The device comprises two conventional pumps, each being equipped with a pressure sensor and being preferably designed as rotary tube pumps. The irrigation pump and the suction drainage pump are connected with each other by way of a control line, and they operate in a master-slave mode. Operation is very simple, in that only the irrigation pump needs to be adjusted and operated by the operator. Control of the suction drainage pump takes place automatically based on the measured values of both pressure sensors in the irrigation and suction drainage conduits and the set r.p.m.'s of the irrigation pump. The primary advantage of the device resides in that the suction drainage pump takes care automatically of uniform pressure and flow relationships at the site of the surgery independently of the adjustment of the irrigation pump.

For enabling the light pipe (2) to be easily exchanged it is provided that the light pipe (2) is configured as a detachable part, that the spatula-shaped portion (10) is provided with a recess adapted for receiving at least an area of the light pipe (2), and that the light pipe is fixed in the recess in its final position. (FIG. 9).

Abstract: A trocar sleeve for endoscopic operations has valve means and seal means on the end of the trocar sleeve remote from the patient. In addition to a seal with a large diameter, at least one support element for a further seal with a smaller diameter is provided.

Abstract: 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 interconnected by means of a first joint so that the first lever is connected by means of a second joint to the slide, while the second lever is connected by means of a third joint to the ring, a connection between its end to the periscope and at its other end by a fourth joint being connected between the two joints of the second lever so that the ratio of the spacing of the fourth joint with respect to the first joint is selected so that there is a smaller periscope displacement than wire loop electrode displacement.

Abstract: An endoscope is provided with an integral optical element which includes a lens system and an objective lens that is recessed approximately 15 mm from the distal end of the endoscope. An integral illuminating element includes a fiber optic bundle that terminates at the distal end of the endoscope and illuminates the region of the distal end. The lens system terminated in a viewing port that is laterally displaced from the proximal end of the endoscope and which connects to a high resolution video camera that can display a magnified image on a high resolution video monitor, thus obviating the need for an unimpaired visual path from the proximal to the distal end of the endoscope. A lumen can be provided adjacent the lens system which brings a ventilating and clearing gas over the objective lens to keep the lens clear. The magnified video image can also be supplied to printers and recorders.

Abstract: 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 doctor to follow the varying direction during insertion of the instrument, because the angle between the head and the eyepiece member can be varied during insertion.

Abstract: 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 this way a sample of precisely that part which has been observed is taken at a very short distance in front of the front lens.

Abstract: The invention relates to a one-hand hysteroscope with a hysteroscope adapter for fixing by vacuum to the portio, in which the hysteroscope shaft and the viewing tube relative to the adapter can be advanced into the body cavity of the patient during hysteroscopy by one-handed operation.To facilitate operation, for mounting the hysteroscope shaft in the hysteroscope adapter, an operating sleeve is provided, which is externally provided with notches for engagement of a movable forceps handle detent of one forceps half for a stepwise advance and which is arranged on the fixed sleeve bearing together with a fixed forceps half.Thus, hand force need only be used when the stepwise advance on the optics takes place with visual observation. Automatic arresting of the optics in any random position is possible, without a given hand force having to be maintained.The one-hand hysteroscope is intended for use in the medical field.

Abstract: An endoscope including a rigid tube containing a rod lens, and a lens next to the rod lens cemented to it. Both lenses are embraced by the tube. The risk of destruction of the cement bond joining the lenses is reduced by reducing the diameter of the rod lens along a major portion of its length spaced from the cement bond. The invention includes a rod lens for this use, which has a reduced diameter for the major portion of its length between its ends.

Abstract: A medical gripping instrument for endoscopy. A sleeve has a passage with a distal opening. A periscope extends axially in this passage, along with at least three springy gripping arms, which also are axially movable. They leave a clear path between them so the periscope can see what they grasp. The arms and periscope are linked so that both move axially simultaneously so the region in the arms remains in the view of the periscope, and an object brought into the shaft by the arms will not harm the periscope.
