Abstract

The invention discloses a pedal positioner for adjusting stretching and bending of a knee joint in operation. Two mutually parallel support plates with bar-type through holes are arranged on a base plate; a sawtooth-shaped surface adjusting and limiting plate is arranged on the base plate and is positioned at the part between the two support plates; two end parts of an adjustment moving shaft can be respectively and movably inserted in the bar-type holes of the two support plates; the adjustment moving shaft can be circumferentially locked in the bar-type through hole; a positioning support plate and a pedal plate are rotatably sheathed on the middle part of the adjustment moving shaft in an opposite direction and are respectively fixed on the adjustment moving shaft by a positioning plate locking screw and a pedal plate locking screw; and one end of the positioning support plate is inserted and positioned on the sawtooth-shaped surface adjusting and limiting plate to be clamped and matched with the sawtooth-shaped surface adjusting and limiting plate. The pedal positioner is simple in structure, low in manufacturing cost, easy and convenient in use and operation, reliable in adjustment and positioning, good in positioning effect and high in reliability and is beneficial for operation; and the operation quality can be ensured.

Description

technical field [0001] The invention belongs to medical equipment, and mainly relates to a foot pedal for adjusting the extension and flexion angle in orthopedic knee joint surgery. Background technique [0002] In knee orthopedic surgery, in order to facilitate the operation and ensure the quality and effect of treatment, doctors often need to adjust the extension and flexion of the patient's legs, and the surgical assistant always holds the patient's legs with his hands to ensure that the adjustment The angle of the knee joint remained unchanged, and the operation was completed smoothly and with high quality. However, in the actual operation process, it is very difficult to accurately control the position of the knee joint manually, which is not only not conducive to the operation of the doctor, reduces the efficiency of the operation, increases the labor intensity of the operation of the medical staff, and especially easily affects the quality and effect of surgical treat...
