The invention discloses an
upper limb functional position training instrument for a patient with
breast tumor undergoing radiotherapy. The instrument comprises a fixing base A, an adjusting plate A, a fixing plate, a stepping motor A, a rotating arm, a positioning sleeve, a gear sleeve, an adjusting rod, a gear clamping plate, a baffle, a spring A, a supporting base, an avoiding groove, a stepping motor B, an electric push rod, a fixing shaft, a regulating and controlling limiting plate, a spring B, a
proximity sensor and a containing supporting cover. Firstly, through the design of small-amplitude reciprocating swing, the upper limbs of the patient can be conveniently exercised in a
small range, the problem of excessive training of the patient during initial exercise can be avoided to the maximum extent while the exercise is improved, and secondary damage is effectively prevented; secondly, with adoption of the regulating and controlling type travel limiting structure,
medical staff can conveniently adjust the amplitude according to the pathogenetic condition and the
rehabilitation degree of the patient, and the instrument can be well matched with the body state of the patient; and finally, multi-directional adjustment and change can be achieved in cooperation with a multi-angle adjusting mechanism, the
rehabilitation requirements of different functional positions are met, and relatively high application and popularization value is achieved.
