An endoscope apparatus comprises a light source unit including a controlling station transmission circuit to serve as a controlling station, and an endoscope unit and an endoscopic camera unit individually including controlled station transmission circuits to serve as controlled stations. The controlling station transmission circuit checks unregistered addresses on its own address table a fixed number of times every time an operation sequence is completed. If a unit connected to the light source...

A dual bladed laryngoscope is disclosed herein. This laryngoscope includes a handle configured to operate with a conventional blade carrying its own light source and one which merely carries a light guide. In this regard, the handle also includes a light source along with a power supply and a mounting base, the latter is designed to receive the first-mentioned blade in a way which automatically causes the power supply to energize the light source carried by this blade. At the same time, this mou...

A sterile covering enabling an endoscope to be attached to or detached from a camera coupling without contamination by either the camera or the coupling. The sterile covering encloses the camera and is disposed within a cavity of a C-mount coupling which couples the endoscope to the camera. The covering includes a system for registering an optically clear portion of the covering, an optically clear film, or an element coupled to the covering with the endoscope-to-camera optical path. In one embo...

Described herein is a device for positioning and fixing an echosignal sensor and sensors of electric signals in an apparatus for taking cardiograms having an echocardiograph and an electrocardiograph. The device has a base with two mutually perpendicular guideways for the movable carriage to travel thereon. The carriage carries a swivel head with a socket for accommodating the echosignal sensor. The swivel head is angularly displaceable in such a way that the centers of rotation of the socket an...

The present invention relates to a hysteroscope which is insertable into the uterus via an entrance adaptor, and consists in a guiding element intended for firm and rigid connection to the entrance adaptor and may be pushed together and pulled apart telescopically by means of handles, a hysteroscope shaft comprising an optical system being insertable through said guiding element and through the entrance adaptor and adapted to be coupled to the proximal extremity of the guiding element.

A method for measuring the metabolic utilization rate of oxygen in an internal organ or tissue, wherein a portion of the organ or tissue to be diagnosed is subjected to interruption of oxygen supply and then measured biospectroscopically. Reflection spectral characteristic variations per unit of time are measured. The measured information is converted into an electrical signal to indicate the metabolic rate.

An expandable fingers medical device which improves surgical speed and precision and enhances patient care and recovery by minimizing anesthesia time, trauma, infection and iatrogenic complications and increases viability of anastomosis. The medical device has fingers which expand and spread out in response to actuation of a control assembly. In the illustrative embodiment, the control assembly has a wrist mounting which holds the fingers and a wire rope for pulling the fingers against the camme...

A suction selector mechanism of an endoscope is operated such that a suction channel member may be connected to or disconnected from a suction tube guided to a control section. The selector mechanism has a first connecting port and a second connecting port. The first connecting port is formed in a cylinder and is connected to the suction channel member. The second connecting port is formed in the cylinder and is connected to the suction tube. A piston is slidably inserted in the cylinder and has...

An endoscope includes a connector portion attached to a universed cord of the endoscope, a gas feed tube and a liquid feed tube each connected at one end to a liquid feed tank, and an insertion member provided at the other ends of the gas feed tube and the liquid feed tube and capable of being attached to and detached from the connector portion. A movable member is provided at the connector portion and is capable of taking a first position in which a gas feed passage and a liquid feed passage of...

A fiberoptic device that facilitates the performance of tracheotomies and a method for performing tracheotomies using that device. The device comprises a relatively short rigid tubular housing sealed at one end and connected at the other to a long tubular sheath. A bundle of optic fibers is contained in the sheath throughout its length. Light may be passed through the fibers and directed to a port near the sealed tip of the housing where it exits. The sheath has distance markings on its surface ...
