Abstract: A hockey stick having the appearance of a solid wood stick and superior handling properties is formed with an outer layer of resin-impregnated wood veneer formed integrally with an inner sheath of fiber-reinforced fabric and resin. In one embodiment of the hockey stick, the two outer layers are formed over a core which may be formed of foamed plastic core. In an alternative embodiment, the foam core extends through the handle area and the blade is formed of synthetic fibers overlaid and bonded to an outer wood veneer sheath by resin which impregnates both layers.

Abstract: A generally U-shaped surgical instrument for prying apart and keeping open the rib cage in open heart surgery. There is a stationary arm with a toothed cross bar attached to it. A movable arm similar in configuration to the stationary arm has a housing at one end which slides on the bar and can be cranked open to force the sternum apart. The housing holds the crank mechanism and a pair of circular bearing inserts. The cranking mechanism is self-locking. One of the inserts is a safety feature, because it can be quickly popped out, should the movable arm become jammed on the bar during the cranking sequence, to provide clearance to unbind the arm on the bar. Both inserts are replaceable and take the wear and tear during the cranking process. New inserts can be inserted to refurbish the instrument. There is a V-clamp that slides on the arms and holds a support rod. There is a castellated clamp that slides on the support rod and it has an articulated extension rod.

Abstract: A rotating grip comprising a non-slip outer surface and a high slip inner surface and which can be installed on the handle of a baseball bat to enhance the user thereof, is described. The grip can be covered by a conventional sleeve-type grip and has a novel notching means to hold the rotating grip in place. When used, the rotating grip enables the proper alignment of the hands to occur automatically and thus create a level and smooth swing. This swing will insure more direct hits on the baseball.

Abstract: In a retractor with a retractor blade, a handle, a fiber-optical light guide for illuminating the point of engagement of the retractor and a connector for connecting a fiber-optical cable to the fiber-optical light guide, with the fiber-optical light guide comprising a bent, tubular sheath which extends through the handle and along part of the retractor blade and in which a glass fiber bundle is embedded, in order to improve resterilizability, with the retractor being at the same time capable of being disassembled, a sheath that comprises fixing elements for detachably securing the retractor blade on the sheath, and the handle being positioned loosely on the rear end of the sheath and fixed in this position by a detachable holding element.

Abstract: A hot or cold body pack utilizing a heat transferring element which includes a bag having a first heat insulative portion and a second heat porous portion. The heat porous portion also mechanically retains a heat transfer element within the bag. The bag includes an opening to retain the heat transfer element. First and second loop members extend along separate dimensions on the outer surface of the bag to permit the straps to hold the bag to a body. Fastener material along an edge of the bag allows it be fastened to another pack.

Abstract: A collapsible tanning booth comprises at least two rear lamp units and at least two front lamp units, each of the units having a thin long casing that includes rear, side, top and bottom walls and a front panel, the front panel being of a material transmissive to ultraviolet light, a reflector panel adjacent the rear wall and lamps mounted between the reflector panel and the front panel. The rear lamp units are hinged together along their adjacent side walls so that they can be moved between a storage configuration in which they are substantially aligned transversely and a use configuration in which they are oblique transversely to each other.

Abstract: This invention relates to hot or cold thermal packs having an outer pouch provided with capillaries to allow drainage of the pack and optionally to provide a temperature moderating effect.

Abstract: A hollow metallic baseball bat is disclosed which includes a large diameter impact section, a small diameter gripping section and a transition section therebetween. The lower end of the small diameter gripping section is configured to provide a reverse conical grip whereby the smaller two fingers of the lower hand of the batter can more tightly grip the bat. In modifications of the reverse conical grip, the lower end of the gripping section can be formed of modified oval configuration or modified elliptical configuration to more comfortably tightly receive the lower hand of the batter.

Abstract: A tibia retractor includes a receptacle into which one's foot can be placed. The receptacle can be adjusted to attain a tight-fitting relationship between the foot and the receptacle. A strap extends from one side of the receptacle and is connectable to the other side of the receptacle. The strap is long enough to pass over the femur so that, when the strap is secured in place, the tibia will be held in a fixed position relative to the femur.

Abstract: A laryngoscope blade having a base member and a blade portion. The blade portion is curved throughout its entire length. The blade portion defines a recessed channel in the top surface thereof, positioned approximately midway between the ends of the blade portion.

Abstract: A hot and cold compress device comprises a heat transmitted element of which one plate grows hot or the other plate grows cold while the current is conducting, a pair of heat conduct elements which can conduct the aforesaid heat transmitted element to grow hot or cold, an adiabatic tie which sleeves the heat transmitted element and the heat conduct elements, two radiating films which are installed symmetrically to coat the two surfaces of the adiabatic tie, two thermometers which are united on the end of the radiating films, a control box which supplies the power of the heat transmitted element and sets the temperature, and a pair of ties which are connected to the two ends of the adiabatic tie. The feature of the present invention is that the device grows cold at one side of the radiating films, while conducting, to reduce the patient's fever. On the other hand, if the polarity of the power supply is changed and reversed, the other side of the radiating films grows hot to provide the patient a hot compress.

Abstract: A laryngoscope curved blade includes a pair of fiber optic bundles, one fiber optic bundle adapted to transmit light to the distal end of the blade and the other fiber optic bundle adapted to provide a viewing channel for telescopic viewing of the area adjacent to the distal end of the blade. A lens attached to the proximal end of the blade gathers and focuses the light transmitted by the viewing channel fiber optic bundle. Additionally, a lamp located on the proximal end of the blade provides illumination down the throat of a patient for line of sight viewing of the person performing the largyngoscope and the light transmitted by the first fiber optic bundle for illumination of the area adjacent to the distal end of the blade.

Abstract: A visible light ray radiation device for use in medical treatment comprises one large optical conductor cable having many smaller optical conductor cables within it, a hollow, transparent, resilient, skirted member, and an air-suction member. The large optical cable is unbound at the end side of it into many smaller optical conductor cables. The skirted member is attached to the end of each smaller optical conductor cable. An air-suction member is attached respectively to each transparent member in order to reduce the inner pressure of the transparent member when the transparent member is attached to the areas of the skin to be cured.
