摘要：
A medical needle protection apparatus (10, 110) comprising: a protection (22, 122) that is extensible from a retracted position to an extended position to enclose a distal end of a needle (12, 112), including said needle a proximal end (18, 118) mounted on a splice sleeve (28, 128) and said protection comprising: an outer bearing (26, 126) having a side wall defining a first inner space around an axis (16, 116) longitudinal； an inner bearing (24 124) having a side wall defining a second inner space around said longitudinal axis, in which said needle is disposed in said second interior space and can be moved along said longitudinal axis, said bearing interior disposed in said first interior space and being able to move telescopically in its interior along said longitudinal axis and in which the inner bearing and the outer bearing remain coaxial throughout the movement of the inner bearing in relation to the outer bearing； a wedge portion (52, 152) pivotally mounted on said inner bearing and being able to move with said inner bearing to pivot and wedge against said needle to secure the distal end of said needle within the second inner space in the extended position； an extension fixation having a proximal end connected to said splice sleeve (28, 128) and a distal end connected to said inner bearing (24, 124) to prevent separation of the protection (22, 122) of the needle in the extended position, in which the extension fixation comprises extensible segments (44A, 44B)； and a hitch that can engage the inner bearing (24, 124) to maintain a hooked structure of the inner bearing (24, 124), the outer bearing (26, 126), the extendable segments (44A, 44B), the needle (12 , 112) and the coupling sleeve (28, 128) in a protective configuration around a tip (32, 132) of the needle when it is retracted in the inner bearing (24, 124), wherein said protection is extensible along said longitudinal axis from said retracted position to said extended position.Un aparato (10, 110) de pr
