摘要： A bone marrow biopsy needle assembly for obtaining a bone marrow core biopsy and a bone marrow aspirate biopsy in a single procedure includes an outer aspiration sheath which closely surrounds a coaxial inner hollow coring needle, and a trocar which extends through the coring needle. A handle arrangement is provided to allow insertion into the bone of the central trocar, the core biopsy needle and the outer aspiration sheath as an assembly, and to further allow stable manipulation of each component of the system without displacing the outer aspiration sheath. After insertion of the combined system through the cortical bone layer, the trocar is withdrawn. Further pushing and, if desired, twisting of the remaining assembly forces a bone marrow core biopsy into the inner, coring needle. The coring needle is then withdrawn and the bone marrow core biopsy is pushed out in a retrograde manner. An aspiration syringe is then coupled to a luer slip on the aspiration sheath handle, and a liquid sample of marrow aspirate is obtained. Thus, a solid core of bone marrow and liquid marrow aspirate are obtained through a single entry into bone, thereby minimizing bone trauma and patient discomfort.

摘要： A thoracentesis sheath catheter assembly includes a catheter connected to a valve body. The valve body is provided with a throughbore coaxial to the catheter for receiving a thoracentesis needle therethrough and a drainage bore in fluid communication with the first throughbore. The valve body is constructed as a first cylindrical portion which is connected to the catheter and a second cylindrical portion of larger inner diameter which is joined to the first cylindrical portion by a tapered inner wall. The second cylindrical portion contains a valve comprising a blocking ball and a spring biased plunger having a throughbore coaxial to the catheter, and is closed with a cap having a central hole and/or a gasket for sealingly receiving the thoracentesis needle. A thoracentesis needle extends through the hole of the cap, the gasket, the plunger, the first cylindrical portion and into and through the catheter. With the thoracentesis needle in place, communication between the throughbore and the drainage bore is blocked and a flow path is established through the needle. When the needle is removed, the throughbore is automatically obstructed by movement of the ball by the plunger along the tapered inner wall. However, a second fluid path is automatically established from the throughbore to the drainage bore.

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： 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： 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： A Verres-type needle which has a sharpened outer needle and allows passage of a blunt inner needle within the outer needle. The Verress needle also contains a position indicator to indicate the position of the inner needle within the outer needle, so that the user knows whether the inner needle is in a protective or non-protective position. Further, a liquid level indicator demonstrates the path of liquid flow within the Verress-type needle. Finally, there is an acoustical enhancment mechanism, which allows the user to know whether the blunt inner needle has sprung forward within the abdominal cavity, to its most forward, protective position.

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.
