摘要： An endoscopic instrument is described having a fluid chamber, a cannula, a shell, a first locking mechanism, and a probe with a second locking mechanism. The fluid chamber has proximal and distal ends. The hollow cannula is coupled to the distal end of the fluid chamber. The port is located at the proximal end of the fluid chamber. The shell houses the fluid chamber, the port, and the first locking mechanism. The probe extends through the port, through the fluid chamber, and through the hollow cannula. In a first fully inserted position, the distal end of the probe extends past the distal end of the cannula. When the probe is partially withdrawn from the shell, the first locking means releasingly engages the second locking means on the probe. Different spring loaded mechanism are described, including one mechanism which is overcome by pulling on the handle of the probe, and another mechanism which requires an active release mechanism.

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： 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.
