A guiding probe, in particular for an endoscope for surgical endoscopy with laser light, wherein the guiding probe comprises a flexible section which is resistant to high temperatures and substantially does not absorb the laser light used, and further including an auxiliary part for introducing the probe.
An articulated pipe used for an endoscope includes articular chips made of brittle material such as a ceramic, with joint pins for joining the articular chips in series. The joint pins are made of shape-memory material. With these joint pins, the brittle articular chips are easily joined together without being damaged.
A radiation coagulator with a radiation source which has a large infrared content and with a sleeve-shaped cap which is placed on the holding tube at the radiation exit end of the light conductor, and with which the area of the tissue to be coagulated is brought into contact.
A lifesaving borescope system comprises a borescope having an insertion section, sensors disposed in the vicinity of the distal end portion of the insertion section, a sensor holder for holding the sensors, and an external output device for displaying or pronouncing information detected by the sensors.
A device for positioning/retaining a transducer relative to a body characterized in that it comprises a supporting member for placement on the body, connected thereto one end of a flexible and elongate arm, which has a mount for the transducer at or near the remote end thereof, and means for locking the arm in a fixed position relative to the body is disclosed. Also disclosed are an apparatus for monitoring aortic blood velocity and derived parameters by Doppler ultrasound and, optionally, ECG comprising such a device and that use of such an apparatus.
A shaft for medical instruments, especially for guiding instruments into body cavities, has neighboring segments that are hollow on the inside and that form sections of the shaft. The segments can be adjusted in their positions by means of control wires so that various shaft curvatures can be set, whereby at least two groups of segments can be adjusted independently of one another. The segments of a first group, provided distally, are flexibly linked with each other. A tensioning device provides a variably adjustable spring force to the segments of the second group such that when under low tension, the segments are non-positively locked, and under high tension, the segments are positively locked.
