Abstract:
An optical head for an endoscope is fitted with an imaging system comprising a solid state imaging sensor and with an illuminating system comprising illuminating means, e.g. LED's. At least one illuminating means is defined by a parameter, which value is different from the value of the same parameter of the remaining illuminating means. Among the parameters are luminous intensity, luminous intensity distribution angle and direction of the longitudinal axis of the illuminating means.
Abstract:
A connector (30) is described, which is suitable for establishing flow communication between passages of a multilumen tubing (31) used with an endoscopic apparatus (10) and between tubes for supplying fluid medium to the multilumen tubing. The connector (30) is adapted for insertion and retraction of a surgical instrument therethrough. The connector (30) comprises a main body portion (46) provided with a through-going bore, which longitudinally extends along the main body portion. The main body portion (46) further comprises a plurality of lateral ports (66, 68, 70), which are in flow communication with the through going bore. The bore is adapted for insertion thereinto and removal therefrom of a proximal end (32) of the multilumen tubing. The lateral ports are adapted for receiving thereinto the tubes for supplying the fluid medium.
Abstract:
Endoscopic apparatus is provided, having a distal end (102) for insertion into a body of a patient and a proximal end that is held outside the body of the patient. The apparatus includes a proximal cylinder (404), disposed in a vicinity of the proximal end of the endoscopic apparatus. A proximal piston (406) is slidably contained within the proximal cylinder. A distal cylinder (328) is disposed in a vicinity of the distal end of the endoscopic apparatus, and a distal piston (310) is slidably contained within the distal cylinder. A tube (402) for containing a liquid is coupled between the proximal and distal cylinders. A tool (e.g., biopsy tool 115) is coupled to be actuated by displacement of the distal piston, so as to perform a mechanical action on tissue of the body or contents of the body, responsive to displacement of the distal piston.
Abstract:
A control system for supplying fluid medium to an endoscopic apparatus which comprises an operation handle and an insertion tube provided with an insufflation channel, an irrigation channel and a suction channel extending therealong. The control system is provided with a system control unit with at least one source of a first fluid medium, with a source of a second fluid medium, with a source of vacuum and with a multifunctional connector for bringing the operation handle in fluid and electrical communication with the system control unit. The source of the first fluid medium and the source of the second fluid medium are simultaneously connectable to and disconnectable from the insufflation channel and the irrigation channel.
Abstract:
Apparatus for sheathing an endoscopic tool (26) includes a sheathing assembly (34), which includes a sleeve dispenser (40) and a port adapter (46) for mating with a proximal port (32) of an endoscopic working channel (24) so as to permit the endoscopic tool (26) to be advanced through the sheathing assembly into the working channel. A flexible sleeve (50) in the sheathing assembly has a distal end (51), which is fixed to the sleeve dispenser, and a proximal end (53), which is adapted to engage the endoscopic tool as the endoscopic tool is retracted from the working channel, causing the sleeve to extend out of the dispenser in a proximal direction so as to sheath the endoscopic tool.
Abstract:
A method and device for cutting and sealing of disposable multilumen tubing (72) is disclosed. The method comprises providing a first surface (64) and an opposite second surface (66), placing a portion of the multilumen tubing (72) between the first and the second surface and applying heat and pressure to at least one of the first and the second surface so as to plastically deform and cut the said portion of the multilumen tubing and to heat-seal the cut ends thereof. The device for cutting and sealing comprises a first jaw and juxtaposed therewith a second jaw, said first and said second jaw are provided with respective first and second surface. The device further comprises biasing member (BM) exerting pressure on at least one of the said first and the second surface and a source of energy suitable for heating of at least one of the said first and the second surface.
Abstract:
A garment (20) to be worn by a patient (22) during endoscopy is cut and sized to fit snugly around a pelvic area of the patient, such that when the garment (20) is worn by the patient (22), the fabric defines two leg holes and an aperture (28), which is positioned adjacent to a body orifice of the patient (22) so as to permit insertion of an endoscope (40) through the aperture (28) into the body orifice.
Abstract:
An apparatus (10) for endoscopic examination of a body passage includes a flexible endoscope and an inflatable sleeve (42), which upon inflation is capable of propelling the endoscope within the body passage. The endoscope is provided with a proximal end (12) and with a distal end (16), which comprises an insertion tube, a bending section (32) and a probe (36). The sleeve comprises a rear folded portion (15) and a frontal unfolded portion (17). The sleeve is detachably coupled with the insertion tube, wherein the rear portion of the sleeve is located behind the bending section. During the endoscopic examination the rear portion unfolds upon inflation and propels the endoscope within the body passage, while the frontal portion remains deflated and covers the bending section and the probe.
Abstract:
A disposable set for use with an endoscope is described. The set comprises a dispenser provided with a longitudinal transit passage adapted for passing the endoscope therealong. The dispenser stores a disposable multilumen tubing fitted at a distal end thereof with a cap that is detachably connectable to an optical head of the endoscope. The dispenser is fitted with a protective sleeve adapted to cover the endoscope during the endoscopic procedure. The dispenser is adapted for receiving a lubricant and distributing thereof within the transit passage.
Abstract:
Apparatus (20) for sheathing an endoscope (22) includes a dispenser (24), having entry and exit ports (36, 39) defining a transit passage through which the endoscope may pass, and a flexible sleeve (26), at least a portion of which is bunched in a vicinity of the dispenser. The sleeve includes a distal end (28), which is closed, and a proximal end, which is open and fixed to the dispenser so that as the endoscope is advanced in a distal direction through the transit passage, the endoscope enters into the sleeve through the proximal end and engages the distal end of the sleeve, thus causing the bunched portion of the sleeve to be extended so as to cover a distal part of the endoscope that protrudes through the exit port.
