Esophagus retractor capable of dynamically monitoring and adjusting traction force

The invention discloses an esophagus retractor capable of dynamically monitoring and adjusting traction force, which is characterized by comprising a traction head, a transition connecting rod, a holding handle and an elastic transition belt, one end of the transition connecting rod is connected to an inner cavity of the holding handle in a damping and sliding mode, the other end of the transition connecting rod is detachably connected with the traction head in a clamped mode, and the elastic transition belt is fixedly connected between the transition connecting rod and the holding handle. The traction head is detachably connected with a flexible pad with a thin film pressure sensor, a driving component is arranged in the holding handle to drive the transition pad to slide in a telescopic mode, and a central processing unit in the holding handle receives monitoring information of the thin film pressure sensor and correspondingly regulates and controls the driving component. The flexible pad which is in flexib
