摘要： A biological forceps device is disclosed for the taking of tissue samples from a body. The biopsy forceps device comprises a flexible main coil having a distal end which is stiffer than the majority of the coil, a pair of opposed jaws hingedly disposed on the distal end of the coil, and an actuator having a distal end coupled to the hingedly disposed jaws for effecting articulation of the jaws. Preferably, shrink wrap tubing is placed on the distal end of the coil and acts as the stiffening agent thereof. A stiffer distal end permits the practitioner to press the jaws deeper into the tissue and reduces the jump experienced at the distal end when the coils go from a state of tension (jaws open) to a state of compression (jaws closed), so that a better sample can be obtained.

摘要： Endoscopic biopsy forceps jaws having an outer edge which may be generally U-shaped, circular, or oblate circular are disclosed with teeth which extend completely around the outer edge. The teeth may take any of several arrangements. In a first arrangement, the teeth and valleys are formed with two substantially rectangular surfaces which meet at substantially horizontal vertex and nadir lines. In a second arrangement, each tooth has a vertex or peak located upward and inward from the outer edge, and is defined by a substantially triangular inner surface, a substantially quadrilateral base, and a surface which extends outward and downward from the vertex of the triangular surface to the outer edge of the jaw. Valleys between the teeth have two inclined surfaces which intersect along a line which extends inward and downward from the outer edge of the jaw. In a third arrangement, the peak of each tooth is defined by the vertex of a pyramid having four faces and valleys between these teeth have three substantially flat surfaces which intersect at a vertex which lies downward and inward from the outer edge of the jaw. Alternate embodiments of all arrangements include providing a lip around the outer portion of the outer edge so that the teeth and valleys are spaced farther in from the outer surface of the jaw cup.

摘要： A firearm suppressor includes a unitary, hollow outer can and a monolithic extruded baffle. The outer can has an interior-threaded proximal end and a radially closed distal end with a longitudinal bore opening the interior of the can to the environment. The monolithic extruded baffle has a proximal end having outer circumferential threads shaped to secure removably inside the proximal end of the outer can and defines a proximal longitudinal bore shaped to receive at least a portion of the firearm barrel and removably secure thereto a distal end defining a distal longitudinal bore with a diameter sufficient to permit a projectile to pass therethrough. The baffle has central baffle walls disposed between the proximal end and the distal end. Each baffle wall has a longitudinal bore axially aligned with the proximal longitudinal bore and the distal longitudinal bore.

摘要： A clip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is adjacent to the jaw assembly and a clip pusher is adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and the lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a portion. The threaded portion engages a threaded member coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.

摘要： A firearm suppressor includes a hollow outer can having an interior-threaded proximal end and a radially closed distal end with a bore, a barrel nut having a barrel bore and an outer-threaded distal threading to the can, and a baffle. The baffle has an intermediate wall with a bore and extends outward to the can interior to prevent fluid passing across other than through the bore. A proximal baffle wall has a bore aligned with the other bores and is shaped to secure to the barrel and extends outward not as far as the outer can interior to permit fluid passage. The baffle is shorter than the can's interior length to have the can, the nut, and the baffle define a plenum extending from the proximal end portion to the nut so that the proximal baffle wall directs fluid from the barrel backwards as a muzzle brake.

摘要： A retractor for manipulating an object includes a body having proximal and distal ends and a retraction device with a head connected to the distal end of the body, a connector movably disposed in the body, and flexible needles of a shape memory material having a memory shape. The needles are connected to the connector and each have a distal tip. The memory shape of the needles include a portion with an arcuate shape biasing the needles in a memory direction out and away from the head and toward the body to position the distal tip of each of the needles closer to the body when the needles are fully extended out of the head than when the needles are only partially extended out of the head. An actuation device is connected to the proximal end of the body and operatively connected to the connector through the body, the actuation device, upon actuation thereof, moves the connector to selectively extend the needles out of the head in different directions and withdraw the needles into the head.

摘要： A low friction sheath for endoscopic instruments is made from an extrusion grade of high density polyethylene (HDPE). The sheath is formed as an extruded polyethylene tube having an inner diameter slightly smaller than the outer diameter of the instrument it will cover. In order to place the sheath over the instrument, a containment sleeve is placed over the sheath and a source of pressurized gas is coupled to one end of the sheath. The endoscopic instrument tube is sealed and inserted into the other end of the sheath. The polyethylene sheath is filled with gas so that it expands against the containment sleeve and the endoscopic instrument tube is pushed into the expanded polyethylene sheath. The gas is released from the polyethylene sheath and it contracts against the outer surface of the endoscopic instrument tube. The sheath is preferably made from a HDPE having a microfractured surface with 10-20 micron fractures.
