The invention provides a traction type rehabilitation device.It mainly provides traction stroke that can greatly increase arm stretching.And then achieve the effect of effectively stretching the muscles and bones.Including a hanger,One reciprocating drive module and two hand holding parts.Two ropes are arranged on the hanger.The reciprocating drive module is arranged on the hanger.The reciprocating drive module comprises a reciprocating drive unit.One motor,One actuator and one controller,The controller stores the timing data of forward and reverse rotation of a motor.Each grip is connected to one end of the rope and hung under the hanger.And the other end of each rope is respectively connected with an actuator.According to the timing data of the motor's forward and reverse rotation, the controller controls the motor's rotating shaft to rotate forward and reverse alternately.The reciprocating drive unit is alternately driven by forward and reverse rotation of the motor.To drive the actuator to and fro.Make each grip move up and down alternately with the actuator.By this way, the patient's hand can make a large-scale reciprocating stretching movement upward.In order to overcome the limitation of conventional traction stroke on the swing amplitude of pedal crank,When using the rehabilitation machine,The reciprocating traction stroke can be flexibly adjusted according to the needs of patients.And improve the convenience of operation.And the utility of rehabilitation effect.本創作提供一種牽引式復健裝置，主要係提供可大幅增加手臂拉伸之牽引行程，進而達成有效伸展筋骨之功效，包括一吊架、一往復驅動模組及二可供手拉的握持件，該吊架上繞設有二繩索，該往復驅動模組設於吊架上，且往復驅動模組包含有一往復驅動單元、一馬達、一引動件及一控制器，該控制器儲存有一馬達正反轉時序資料，各握持件分別連接繩索一端且懸掛於吊架下方，且各繩索另一端分別連接引動件，該控制器依據馬達正反轉時序資料控制馬達之轉軸交替進行正轉及反轉運作，該往復驅動單元接受馬達之正轉及反轉交替驅動，以驅動引動件往復移動，使各握持件隨著引動件上下交替往復移動，藉此提供病人手部向上做出大幅度的往復拉伸運動，以克服習知牽引行程受限於腳踏曲柄擺動幅度之缺失，於使用復健機時，可根據病人需要靈活調整往復牽引行程，進而提升操作上之便利性，以及復健功效上之實用性。
