摘要： A skull pin provides greater resistance to shear forces so that it may be more readily made of titanium, ceramic or gem stone, yet still prevents undue penetration, and can be tightened if wear or erosion of the skull results from cyclic loading. The pin is used with a halo or cervical traction ring, and has a main, externally threaded, circular cylindrical body, and a skull engaging portion. The skull engaging portions is formed by first and second concentric, in-line cylinders terminating in conical sections, the first conical section terminating in the second cylinder (which resists shear forces much better than conventional skull pins), and the second conical section terminating in a pointed tip. The first cylinder has a diameter of about 0.18 inches, the first conical section has a length of about 0.09 inches and approximately a 60.degree. taper angle, the second cylinder has a length of about 0.03 inches and a diameter of about 0.07 inches, and the second conical section has approximately a 60.degree. taper angle.

摘要： A bone penetrating pin for medical use includes, in one embodiment, a shank provided at one end with a bone penetrating element of titanium or single crystal alumina ceramic material, and a driving head at the other end. A removable cap is applied to the driving end, the cap including upper and lower cylindrical portions of substantially identical diameters interconnected by an intermediate portion of substantially smaller diameter. The upper portion is formed with oppositely extending arms for application of torque through the cap to the shank and bone penetrating element. The intermediate portion of the cap is designed to fail in shear upon the application of torque in excess of a predetermined maximum; that is, it provides a torque limiting function. In another embodiment, the torque applying and limiting means are in the form of a tool assembly comprising a shank engageable with one end of a bone penetrating pin, and a cap slidable with respect to the shank, wherein a torque limiting insert is receivable between the cap and the shank to drivingly couple the two. More specifically, the tool of this second embodiment includes an elongated shank provided with a pin fastener engaging tip at one end and a first socket formed at the other end. A torque applying device is slidably mounted with respect to the shank, and includes a second socket substanially aligned with the first socket. A torque limiting insert is receivable within the first and second sockets to couple the torque applying device and the pin engaging shank.

摘要： Cervical traction tongs having cooperating first and second curved arms made of MRI and biologically compatible and CT transparent material. Skull pins having main bodies of MRI and biologically compatible and CT transparent material, and pointed skull engaging tips of radiolucent material (e.g. single crystal alumina ceramic) extend through openings at one end of the arms, while at the other ends the arms are connected together in an adjustable manner, so as to adjust the spacing between the pin pointed tips. The arms have enlarged circular end terminations having radially extending serrations which cooperate together, and are held in a position to which they are moved by a through extending bolt and nut. The arms have sufficient elasticity to provide constant pressure urging the pointed pin tips against the human skull during use. A flexible strand for applying tension is passed through an arcuate elongated opening in the serrated end terminations of the arms. Torque limiting caps associated with the pins apply torque. When used to treat a human with an injury to the cervical spine, the tongs and skull pins are removed from sterile packaging, and once the human need no longer remain in traction, the tongs are disposed of.

摘要： A portable cervical traction device is utilized to temporarily positively maintain cervical traction while a patient is transported from a stationary traction station to another station, such as an X-ray station. While the patient is in traction at a traction station, the backplate and shoulder supports of the portable device are attached to the patient. Upstanding from the backplate are a pair of telescoping components with compression springs, and at the top of those components is a cross bar. Slide rods extend outwardly from the cross bar to overhang the shoulder supports, and a slide bar slides along the slide rods. A cam cleat on the slide bar is moved into engagement with the traction cable at the traction site, and suitable counter-traction force is applied by compressing the springs associated with the telescoping components. Then the traction cable is released from its attachment at the traction station, and is wrapped around a deck cleat. The device is utilizable with a cervical strap, tongs, halo, and like traction-facilitating devices.

摘要： The skull of a patient is immobilized utilizing a generally ring-shaped member (crown) that can be used in place of a conventional halo or tongs, and is affixed to the patient's skull utilizing particularly advantageous skull pins. The crown has a first major portion which is in a first plane, and has a second portion extending at an angle out of the first plane. Preferably it has a generally horseshoe shape in plan view, with first and second ends spaced from each other, those ends being part of the second portion of the crown. Skull pins pass through threaded openings in the crown, including threaded openings in the second portion to attach the crown below a capital distal plane extending between the top of the ears and the top of the eyes of the patient's head. The rigid crown is preferably of a boron fiber or graphite fiber reinforced plastic. The skull pins, which do not artifact any more than bone does, comprise an exteriorly threaded cylinder of plastic (e.g. boron or carbon fiber reinforced plastic), and a skull engaging portion rigidly connected to the cylinder and extending outwardly from a first end of the cylinder and terminating in a pointed tip. The skull engaging portion is of a ceramic material, preferably a single crystal alumina ceramic material.

摘要： Interlocking surface elements are created in such a way that there is almost 100% engagement between the surfaces, so that they positively lock together, and will not cam with respect to each other. Each element comprises a number of uniformly dimensioned semi-conically shaped surfaces emanating from a common center and disposed in an alternating inverted configuration. Each surface has first and second edges extending in a longitudinal direction. A flat surface of substantially constant dimension in a plane substantially perpendicular to the longitudinal direction connects the first and second edges of adjacent, alternately inverted, semi-conically shaped surfaces, so as to maximize the engagement area between the elements. The elements may be of vacuum formed plastic, molded plastic, or metal stampings. They may be circular (e.g. disc shaped) in plan, and the semi-conically shaped surfaces may all be hollow.
