A method of and an instrument for locating a suprapubic incision into the bladder and for inserting a viewing unit through the incision into the bladder. A telescope for viewing the interior of the bladder is insertable thereinto through the viewing unit. The viewing unit may be left in place for later viewing of the interior of the bladder therethrough, and may be sutured to the abdominal wall. Also, a retention catheter may be inserted into the bladder through the viewing unit. The insertion i...

An envelope fitted to an endoscope provided with a flexible connection tube used in observing the stomach and liver, thereby enabling said flexible connection tube to have the same function as a rigid connection tube used in observing the abdominal and breast cavities.

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.

An endoscope with guiding apparatus is described herein. A steerable endoscope is described having an elongate body with a manually or selectively steerable distal portion, an automatically controlled portion, a flexible and passively manipulated proximal portion, and an externally controlled and manipulatable tracking rod or guide. The tracking rod or guide is positioned within a guide channel within the endoscope and slides relative to the endoscope. When the guide is in a flexible state, it c...

An improved colonoscope and method of removing or adding non-distal fluid from the colon during colonoscopy using a colonoscope. The colonoscope having at least a distal port and a non-distal port or plurality of non-distal ports to remove fluid from a shared channel within the colonoscope. Utilizing multiple ultrasound probes to determine a three dimensional image of anatomy behind the wall of a colon. Using microprocessors, motors to tighten/release wires of the colonoscope. Method of using an...

An endoscope having a guide tube is described herein. The assembly has an endoscope which is slidably insertable within the lumen of a guide tube. The guide tube is configured to be rigidizable along its entire length from a relaxed configuration. The endoscope has a steerable distal portion to facilitate the steering of the device through tortuous paths. In the relaxed configuration, a portion of the guide tube is able to assume the shape or curve defined by the controllable distal portion of t...

A method for inserting an endoscope into the colon of a patient includes providing a generally rigid insert having proximal and distal ends and having a curved channel passing therethrough with a lateral opening at the distal end. The insert is inserted into the patient's rectum so that the distal end is in proximity to the sigmoid flexure of the colon. The endoscope is then passed through the channel and into the sigmoid colon.

The invention relates to a sealing device for a rectoscope for attaching on a sealing receiver of the rectoscope, and includes a sealing and an additional sealing element, where the sealing has a clip for securing to the sealing receiver of the rectoscope, an end surface with an aperture for introducing a medical instrument, and a sealing sleeve connecting the clip and the end surface to one another and where the end surface is mounted so as to be tiltable with respect to the rectoscope.

A cannula including a guide and a cam housing rotatably supported about the guide into which a trocar obtuator and an endoscopy instrument may be inserted. A tapered proximal surface of the guide and a cooperating pin on the instrument rotate the instrument into proper rotational alignment. An axial slot extending from the distal end of the taper and a cooperating axial slot in the cam housing are aligned so that as the pin continues to slide axially into the cannula, the pin will interfere with...

An endoscope insertion cannula assembly including an endoscope housing and axially projecting body having an endoscope tip. An adapter is affixed about the endoscope housing, and a guide is affixed about the adapter. A spring and a seal are also affixed about the adapter. The endoscope instrument, together with the associated adapter, spring and guide, are inserted into a cannula housing. A pin on the inside of the cannula housing interacts with an angled slot on the distal surface of the guide ...
