    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： An endoscopic suctioning instrument with variable suction is disclosed. The instrument has a hollow cannula having a proximal end and a distal end, and sliding sleeve having a proximal end and a distal end and a longitudinal axis, with the sliding sleeve being coaxial to and closely surrounding and slidingly engaging the hollow cannula. The sliding sleeve has a plurality of lateral holes at its distal end with the lateral holes being spaced along the longitudinal axis. A valve is provided for selectively coupling a suction source to the proximal end of the cannula, and a sleeve actuation mechanism is provided for sliding the sliding sleeve from a first position where the distal end of the sliding sleeve extends beyond the distal end of the cannula such that a first number of the lateral holes are unblocked by said cannula, to a second position where the distal end of the sliding sleeve extends beyond said distal end of the cannula such that fewer lateral holes are unblocked by said cannula, to a third position where the cannula blocks all of said lateral holes of the sliding sleeve. Various embodiments are described with different mechanisms for causing the sleeve to slide, including mechanisms linking the valve to the sleeve.

    摘要： Medical instruments are provided having end effectors and end effector actuator apparatus which are rotatable relative to the end effectors. The instruments generally include a tube which is typically coupled to the end effectors via a clevis around which the end effectors pivot, a push rod extending through the tube and coupled to the end effectors, and an actuator apparatus engaging the tube and the push rod with the actuator apparatus including a handle which surrounds and rotatably engages the proximal end of the tube, and a lever arm which pivotally engages the handle and is coupled to the push rod such that pivotal movement of the lever arm relative to the handle effects axial movement of the push rod relative to the tube and pivotal movement of the end effectors. In order to alternatively fix or allow rotation of the actuator apparatus relative to the tube and end effectors, the tube is provided with a plurality of peripherally spaced apart recesses in a portion thereof, and the handle is provided with a resiliently biased contact element which is coupled to an electrode and which when seated in a recess restrains rotation of the outer tube about the longitudinal axis, but which can be unseated by a sufficient relative rotational force. To decouple rotation of the push rod from the lever arm, a generally spherical push rod engaging element is provided in a cylindrical bore of the lever arm.
