摘要： A trapezium-metacarpal thumb joint prosthesis having a metacarpal component for insertion into a metacarpal bone of a human thumb and a trapezium component for insertion into a trapezium bone of a human thumb. The metacarpal component has a forward end of generally truncated hemispherical shape with a convex surface and a rear end having a base and a stem. The trapezium component has a forward end of a generally cylindrical shape with a concave surface with a radially built up shoulder and a rear end having a base and a stem. The concave surface is adapted for non-captive rotational abutment with the convex surface. Also, a related method for implantation of the prosthesis into the metacarpal and trapezium bones of a human thumb, wherein the two components are respectively inserted into a pre-cut void in each of the respective bones from a direction above the radial side of the thumb substantially transverse to the longitudinal axis of each respective bone of the thumb.

摘要： A thigh restraining apparatus especially useful in connection with arthroscopic knee surgery wherein the surgeon may perform the operation while viewing the knee on a television screen. A bar member extends across the operating table supported by horizontally extending rail members customarily provided on operating tables. A specially designed sphygmomanometer constitutes a tourniquet member and applies a known pressure to the thigh of the patient. A strap member envelops the thigh of the patient and is reeled out or in by a screw feed as required to accommodate the patient's thigh. One end of the strap is secured and an intermediate portion is removably attached to the sphygmomanometer. If necessary, both knees may be operated upon sequentially without disturbing a required sterile field by positioning a pair of strap feeding devices on opposite sides of the bar member and securing each strap to an adjacent sphygmomanometer applied to each of the patient's thighs.
摘要翻译： 一种特别适用于关节镜膝关节手术的大腿限制装置，其中外科医生可以在电视屏幕上观察膝盖时执行操作。 杆构件延伸穿过由通常在操作台上提供的水平延伸的轨道构件支撑的操作台。 特别设计的血压计构成止血带构件，并将已知的压力施加到患者的大腿上。 带状部件包围患者的大腿，并根据需要卷绕出来或通过螺丝进给，以容纳患者的大腿。 带的一端被固定，并且中间部分可移除地附接到血压计。 如果需要，可以顺序地操作两个膝盖，而不会干扰所需的无菌区域，方法是将一对带子进给装置定位在杆件的相对侧上，并将每个带固定到应用于每个患者大腿的相邻血压计上。

摘要： Cutting-suctioning instrument having an elongated support and first and second, opposed distal jaws, at least one of which is pivotable about a transverse axis and adapted to be closed by an actuator, and a suction throat defined between proximal portions of the two jaws. Preferably, a sliding inner tube, which defines the suction passage, serves as actuator to move the pivotable jaw. As a cutter for meniscal cartilage, a hollow tube defining a tissue-fragment transport, suction passage is arranged to communicate through the open throat with the region between the jaws to receive cut tissue while suction is associated with the proximal end of the instrument for enabling tissue to be drawn from between the jaws, through the throat and then through the transport passage while the instrument remains in situ for repeated cutting. Preferred embodiments of the instrument are especially useful in arthroscopic surgery.

摘要： A reduction and fixation tool has two principle component parts—an intra-articular spoon with a blade, and a handle that docks with the spoon. The spoon has a proximal hub onto which the handle docks. In one example of the tool as it would be used with a fractured scaphoid, the spoon has a distal blade, curved and narrow to slip beneath the undersurface of the scaphoid and to lift the distal fragment of the bone back into proper alignment (fracture reduction). The handle, docked to the spoon, serves as a lever to easily accomplish the reduction, and as a guide for the central insertion of a guide wire into the scaphoid across the fracture site.

摘要： A hand held surgical instrument for use in removing body tissue from a human body. It is particularly useful in arthroscopic surgery of joints such as of the knee or shoulder, but may also be used to remove tissue from the stomach, abdomen, jaw or other portions of the body. An auger-like helical cutter is motor driven at speeds in excess of 1,000 rpm within a stationary outer cylindrical sheath member. The helical cutter is ground to provide a generally concave distal end which gives it a generally fish-tailed appearance and the ability to cut endwise, i.e., to effect an axial boring cut. In addition, the cylindrical sheath member is provided with a pair of longitudinally extending, diametrically opposed tab members at its distal end. Each of the tabs has at least one longitudinally extending edge thereof ground to provide a cutting edge which co-acts with the auger-like cutter blade to sever body tissue insertable between the tabs.

摘要： A surgical router for cutting anatomical tissue includes an outer tubular member and an inner member rotatably disposed in said outer member and having a pair of router blades disposed distally of a distal end of the outer member and equally spaced about a longitudinal axis of the inner member and a pair of flutes disposed between the router blades. The flutes have bottoms and sides transverse to the flute bottoms, with the flute bottoms angularly intersecting a passage in the inner member to form aspiration ports within and integral with the flutes. The router blades have leading walls, trailing walls and clearance walls with a width between the trailing walls that is tapered in a distal direction. The leading walls correspond to the flute sides and are curved about the inner member axis in the direction of rotation of the inner member in the outer member. End and side cutting edges are disposed along the leading walls with the end cutting edges being curved about the inner member axis in accordance with the curvature of the leading walls, and the side cutting edges extending longitudinally, helically along the inner member. Center cutting surfaces join the clearance walls and the leading walls at notches at the inner member distal end, and the junctures of the center cutting surfaces with the clearance walls define center cutting edges angled from the end cutting edges in the direction of rotation of the inner member in the outer member.

摘要： A shoulder traction applying apparatus which clamps to an operating table. The forearm of a patient is gripped by a tapering sleeve-like member and a cord therefrom is entrained over a pair of pulleys at opposite ends of a boom member. The remote end of the cord is selectively weighted to apply tension to the cord and achieve a desired traction. The boom is secured to the top member of a pair of separable members of which the lower member is clamped to the operating table. The top member is rotatable by a hand crank which turns a worm gear that meshes with a spur gear fixedly secured to the top member. The lower member may be raised or lowered by cranking a pinion of a rack and pinion assembly wherein the rack is mounted on the lower member. Hand controlled spring pressure locks the lower member in the position selected by the rack and pinion assembly. A caster-mounted stand stores the top and lower members when the apparatus is not in use.
