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.

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, an actuator apparatus engaging the tube and the push rod and imparting reciprocal axial motion to the push rod relative to the tube, and end effectors. The actuator apparatus includes a sleeve, spring, handle, and lever arm. The sleeve is movable along the longitudinal axis of the tube against a biasing force of the spring, but is restrained from rotating about the tube. The sleeve has a locking element on its proximal end. The handle surrounds and rotatably engages the proximal end of the tube and has a locking element on its distal end which mates with the locking element of the sleeve and disengages therewith when the sleeve is advanced along the tube. Upon disengagement, the tube, push rod, and end effectors can be rotated. The lever arm pivotally engages the handle and is coupled to the push rod such that pivotal movement of the lever arm relative to the handle effects movement of the push rod relative to the tube and pivotal movement of the end effectors. To decouple rotation of the push rod from the lever arm, a generally spherical push rod engaging element is provided in a generally cylindrical bore of the lever arm.

摘要： Releasable ratchet mechanism for medical instruments such as endoscopic instruments are disclosed. The ratchet mechanism includes: a leaf spring with a locking barb which is located on a handle of the medical instrument; a ratchet on a lever arm of the medical instrument which lever arm is pivotally engaged to the handle; and a latch on the handle of the medical instrument. The latch on the handle engages and resiliently deforms the leaf spring to cause engagement of the locking barb in a groove of the ratchet when the latch is in a first position. When in a second position, the latch releases the locking barb from the ratchet groove. Preferably, the locking barb has an extending edge surface on an axis which is substantially parallel to the pivoting axis of the handle and lever arm, and the teeth of the ratchet have extending edge surfaces on axes substantially parallel to the extending edge surface of the locking barb. Also, preferably, the edge surfaces of said teeth of the ratchet are located along an arc of a cylinder having the handle/lever arm pivot axis as its center line.

摘要： An endoscopic tool for dispensing units of hemostatic agent broadly comprises a hollow tube which holds a plurality of individual units of the hemostatic agent, a valve at the distal end of the hollow tube which permits the hemostatic agent to pass therethrough but prevents foreign matter from contacting the hemostatic agent while in the tube, a plunger which extends into the hollow tube and contacts a proximal unit of the hemostatic agent, and a mechanism for moving the plunger distally in incremental movements to cause, upon each incremental movement, an individual unit of the hemostatic agent to be pushed through the valve. Typically, the mechanism for moving the plunger and the proximal end of the hollow tube are held in a handle. One mechanism for moving the plunger utilizes a portion of the plunger as a ratchet by forming a plurality of conical elements thereon, and utilizes a switch in the handle which has a V-spring coupled thereto as a pawl for advancing the conical elements. A second mechanism utilizes a regularly shaped notched cutout in the handle as the ratchet, and a vertical protrusion on the plunger which extends through the cutout as an engagement element. The notched cutout provides resilient stops, and the protrusion is shaped to allow it to be forced in a forward direction through each resilient stop and then to sit in another notch.

摘要： A biological forceps device for the taking of tissue samples from a body, comprising a flexible main coil attached at its distal end to a pair of homologous cast jaws. The jaws have radially arranged teeth on their distalmost end. The jaws are opened and closed by attachment to a pair of pull wires which extend through the main coil, into a handle at its proximal end. The handle has a spool which slides about a central shaft attached to the main coil. The spool is attached to the pull wires, so that movement of the spool with respect to the central shaft, effectuates a force on the proximal ends of the levered jaws, to open and close them, appropriately.
