    摘要: A probe for use with an endoscopic suction-irrigation instrument is disclosed which permits a second probe to be inserted therethrough. The suction-irrigation instrument has a cannula, a fluid chamber having at least one port for irrigation and suction and a proximal opening, and a first seal in the proximal end of the fluid chamber. The fluid chamber has a distal end communicating with the cannula. The probe has a proximal handle portion, a middle portion, and a hollow distal portion. The handle portion has an axial passageway and a second seal therein. The middle portion extends from the handle portion through the first seal at the end of the fluid chamber and through the fluid chamber. The middle portion has an outer diameter shaped to contact the first seal such that the proximal end of the fluid chamber is sealed. The middle portion is also shaped to be smaller than the inner diameter of the fluid chamber, and the middle portion is provided with a second axial internal passageway extending therethrough. The distal portion extends at least partially through the cannula and has an outer diameter smaller than the inner diameter of the cannula. A second probe may be inserted through the second seal of the first probe, through the axial passageway in the handle portion, through the internal passageway in the middle portion, and out through the distal portion and the cannula.

    摘要: A cautery probe is described for use with an endoscopic instrument where the endoscopic instrument has an electrical contact located therein. The probe includes an insulated handle which extends out of the instrument, a conductive probe element which is mounted in the insulated handle and extends through the distal end of the endoscopic instrument, and an insulating cover. The conductive probe element has a distal cautery surface, and an electrical contact surface at a location between the proximal end of the conductive probe and the distal cautery surface, with the electrical contact surface contacting the electrical contact in the endoscopic instrument when said cautery probe is inserted in the endoscopic instrument. The insulating cover substantially covers the conductive probe element from the insulated handle up to but not at the electrical contact surface, and substantially covers the probe element from a point beyond the electrical contact surface, up to but not at the distal cautery surface. Preferably, the cannula of the endoscopic instrument is used as the electrical contact, and the electrical contact surface of the probe element is a bump which contacts the cannula.

    摘要: An electrocautery suction/irrigation endoscopic instrument having an electrocautery safety override is provided. The instrument preferably includes a cannula, an irrigation conduit in fluid communication with the cannula, an irrigation valve for regulating fluid flow in the irrigation conduit, an actuator coupled to the valve, an electrocautery probe coupled to a source of current, and an electrical switch coupled to the source of current and to either the irrigation valve or to the actuator. When the actuator is activated to permit fluid flow through the irrigation conduit, the switch is switched and prevents the flow of cautery current from the current source to the electrocautery probe. Preferably, the switch opens a DC circuit which is used to signal the current source to provide an high voltage AC electrocautery current. Alternatively, the switch may be located in the high voltage AC circuit. Both foot and thumb activated cut/coag switches are disclosed for use with the instrument.

    摘要: Various embodiments of flexible plastic tubing are disclosed for connection to an endoscopic instrument having suction, irrigation and electrocautery capabilities, with the electrocautery capability requiring connection to an electrical wire. Generally, the tubing is an integral, extruded flexible plastic tube having a first suction portion with a first interior cylindrical passageway, a second irrigation portion with a second interior cylindrical passageway, and a third portion with a third passageway for the electrical wire. The third portion joins the other portions. The third portion has a substantially cylindrical interior passageway with first and second flexible lips defining a peripheral opening which is narrower than the electrical wire such that the electrical wire is inserted past the lips and held in the passageway and is removable from the passageway.

    摘要: A surgical trocar assembly includes a disposable valve assembly, a cannula assembly, and a trocar with a handle. The cannula assembly includes a cannula base having a valve assembly coupling device at its proximal end, and a cannula extending from its distal end. The disposable valve assembly has a coupling device for removably coupling it with the cannula base. The valve assembly also includes a valve body with a fluid passage communicating with the hollow cannula when it is coupled to the cannula base. A slit or flapper valve and a universal washer are mounted within the valve body and allow the insertion of the trocar or other endoscopic instruments therethrough while providing a fluid sealing of the fluid passage. The valve assembly may be provided with a side port which optionally contains an automatic valve actuated by a luer coupling. Several different valve assembly-cannula base couplings are disclosed as well as several different types of trocars.

    摘要: A probe for use with an endoscopic suction-irrigation instrument is disclosed. The endoscopic suction-irrigation instrument has a cannula, a fluid chamber having a proximal opening, a seal at the proximal opening, an irrigation port and a suction port, with the distal end of the fluid chamber communicating with the cannula, and the proximal end of the fluid chamber having a substantially cylindrical portion between the irrigation and suction ports. The probe of the invention has a proximal cylindrical portion, a middle portion, and a hollow distal portion. The proximal cylindrical portion has an outer surface which extends through and contacts the seal such that the proximal end of said fluid chamber is sealed. The middle portion extends through the substantially cylindrical portion of the fluid chamber and creates an annulus therebetween. The middle portion has an internal passageway with lateral openings. The passageway is in fluid communication with the hollow distal portion of the probe, while the lateral openings are in fluid communication with the annulus. O-rings around the middle portion divide the annulus into two or more sections such that the irrigation and suction ports are separated. Different probe embodiments permit suction through an annulus and irrigation through the probe and vice versa.
