In medical researches,large-scale collaborations spanning institutions and disciplines have emerged a key pattern for tackling major research subjects.Contract writing for medical research collaboration,as a legal means to address the rights and obligations of the parties,should be fair,reasonable,scientific and strict as much as possible.The author probed into problems found in current writing of medical research contracts,and came up with corresponding remedies.

AIM: To introduce a new kind of wrist-hand orthosis.METHODS: The major frame of wrist-hand orthosis is composed of dorsal carpal guard plate and carpal bracket; while, a U-shaped anterior bracket is fixed on the anterior side of the major frame. Ferrules of index finger, middle finger, fourth finger and little finger respectively connect to dorsal carpal guard plate of the major frame via elastic brace; ferrule of thumb is fixed on one side of ferrule of index finger by using steel wires; an abduct elastic sleeve is designed on the lateral dorsal carpal guard plate of ferrule of little finger by using steel wires. According to experimental demands, wrist with the palms upward or downward puts into the major frame, which is composed of dorsal carpal guard plate and carpal bracket. The hand is anterior to the major frame; ferrules are located over rolling sleeve by forward and fingers are located below the rolling sleeve by forward; ferrules are respectively rang the index, middle, fourth and little fingers; ferrule of thumb is rang the thumb. Continuously, wrist rotates based on orthopaedic demands to realize various orthopaedic functions.RESULTS: The wrist-hand orthosis is used to help the hand maintain extension after extensor tendon injury operation in order to restrict active areas of fingers and promote healing of injured side. On the other hand, this new orthosis is also used to help wrist joint and digital joint maintain flexion after extensor tendon injury operation in order to improve flexion and extension of wrist joint, enlarge active area of flexion of wrist joint, enlarge drifting active area of radialis of wrist joint, and increase muscle strength of radial flexor muscle, ulnar flexor muscle, extensor carpi radialis muscle, extensor carpi ulnaris muscle, extensor carpi ulnaris muscle, flexor carpi ulnaris muscle, extensor digitorum communis muscle, superficial flexor muscle and deep flexor muscle.CONCLUSION: The wrist-hand orthosis refers to protection of wrist and hand after operations of nerve, tendon, muscle and vessel injuries and recovery of motor dysfunction of wrist joint and digital joint induced by wrist-hand fracture; on the other hand, this new orthosis can improve active area of wrist joint and strengthen muscle force.
