A carpal tunnel splint for being custom-fitted to a hand and wrist to be supported, and comprising an elongate, narrow flexible inner cushion layer for being placed on and conformed to the shape of the hand and wrist, an initially flexible intermediate layer overlying the inner cushion layer and an intermediate layer comprised of a fabric impregnated with a moisture-curable resin which hardens upon curing to form a rigid structure of the fabric which retains a shape into which it is molded during curing, thereby also holding the flexible inner cushion layer in a conforming shape against the hand and wrist. A flexible protective outer layer overlies the intermediate layer and is attached to the inner cushion layer for enclosing the intermediate layer and forming the inner layer, intermediate layer and outer layer into a single, integrated elongated, narrow splint structure.

An endoscopic tool utilizes a fiber optic system for illuminating and imaging ligaments or other tissue which are to be cut. Illumination and imaging is performed above a lateral opening at the distal end of a probe that is inserted into an incision point. Preferably, a two edged blade which can be moved in both the distal to proximal direction and the proximal to distal direction is selectively deployable from of the lateral opening at the distal end of the probe. The endoscopic tool is small in size, and preferably includes a pencil grip with a button actuator for deploying the two edged cutting blade. A wire actuator that fits into a slot in the bottom of the deployable blade, can be nested with the fiber optic cable such that the cross sectional area of the probe is reduced. Alternatively, a tube concentric with the fiber optic cable can be used as the mechanism for actuating the blade or other device. The surgeon can observe cutting of the ligament or other tissue as he moves the endoscopic tool in either or both the forward or reverse direction on a display screen which is operatively connected to the fiber optic system. A retractor can be used in conjunction with the endoscopic tool to lift tissue where dissection is desired, and to function as a guide for the blade.

A wrist support comprises a glide member, comfort support and attachment means for attaching the wrist support to a wrist of a user.

A hand stretching method and apparatus mimics a well known exercise to reduce the problems with repetitive stress injury. A body of resiliently deformable material has flat and parallel top and bottom surfaces, with a cutout at one edge of the body. A user's hand is placed on the body, with the palm of the hand spanning the cutout. By pushing down on the hand, the opposite sides of the palm are urged apart, opening the carpal tunnel and relieving compression on the blood vessels and nerves. A user may place one hand on each surface of the body and urge the hands towards each other for treatment of both hands simultaneously. The body is preferably made of an expanded polymeric material such as polyurethane. Layers having different compression factors may be utilized; and, darker colored surface layers of material may be adhered to the top and bottom surfaces so the surfaces will not readily show dirt.

A new ergonomic accoutrement adapted to be attached to a computer mouse was developed to prevent strain injuries to the hand and wrist and prevent or alleviate the symptoms associated with Carpel Tunnel Syndrome (CTS) for those who are repetitive users of computer mouse devices. The accoutrement is designed to leave the carpal tunnel of the user of a computer mouse substantially open, thus precluding tunnel narrowing and the symptoms resulting therefrom. The accoutrement is also designed to maximize comfort of the user, alleviate wrist bend associated with use of the mouse, and be adaptable to different size hands.

Handles allow hand tools, implements or other utensils to operate within their arc of natural use, motion and attack without requiring extension, flexion, radial deviation, or ulnar deviation of the wrist from the neutral plane of the forearm. The preferred embodiments further include a grip shaped to increase the effectiveness of the tool and minimize antagonism between muscles and tendons of the wrist, forearm and upper arm, while maximizing the effectiveness of the gripping force delivered to it by the user. Maintaining the wrist and forearm in a neutral position increases a tool user's potential strength by increasing the synergy between large muscles of the forearm and upper arm and shoulders. It also decreases compression of the tendons and nerves in the carpal tunnel and between the wrist and forearm. Grips according to the invention preferably conform in shape, diameter and dimensions to the physical architecture of the hand such that grip tension and compression of the tendons in the wrist and forearm is optimized, minimizing the compressive force on the small muscles, tendons, and ligaments of the fingers, hand, wrist, and forearm, while maximizing the contributive effectiveness of the larger muscles of the forearm, upper arm and shoulder.
