Shoulder arthroscopy operation traction frame

Abstract

The invention discloses a shoulder arthroscopy operation traction frame, and relates to the technical field of medical instruments. The traction frame comprises a base, a support upright column, a cross beam and a traction rope, wherein the lower end of the support upright column is fixedly arranged on the base, a rotatable adjusting rod is arranged at the upper end of the support upright column,the cross beam is fixedly arranged at the upper end of the adjusting rod, the left and right ends of the cross beam are each provided with a fixed pulley, a rotating shaft is arranged at the left endof the cross beam, a wheel frame is fixedly arranged on the rotating shaft, a guide pulley is arranged on the wheel frame, the guide pulley is located at the lower left of the left fixed pulley, the central axis of the rotating shaft is vertical, the central axis of the rotating shaft is tangent to the left fixed pulley and the guide pulley, the traction rope is wound around the guide pulley, theleft fixed pulley and the right fixed pulley, a tray used for placing a balancing weight is fixedly arranged at the right end of the traction rope, and a dynamometer used for metering the pulling force is bound to the left end of the traction rope. The traction frame provided by the invention is suitable for a shoulder arthroscopy operation.

Description

technical field [0001] The invention relates to medical equipment technology, in particular to a technology of a traction frame for shoulder arthroscopic surgery. Background technique [0002] There are many patients with periarthritis of the shoulder and rotator cuff injury who need to be treated with shoulder arthroscopic surgery. Most of the shoulder arthroscopic surgery requires the patient to adopt a lateral position, and the patient's upper limb on the affected side needs to be tractioned during the operation. The existing traction frame for shoulder arthroscopic surgery for upper limb traction has a relatively simple structure. It only needs to pass the traction rope around two fixed pulleys, set a counterweight at one end of the traction rope, and bind the other end to the upper limb of the patient's affected side. When it is necessary to change the traction direction during the operation, the traction frame needs to be rotated as a whole, and after the traction dire...

The existing traction frame for shoulder arthroscopic surgery for upper limb traction has a relatively simple structure. It only needs to pass the traction rope around two fixed pulleys, set a counterweight at one end of the traction rope, and bind the other end to the upper limb of the patient's affected side. When it is necessary to change the traction direction during the operation, the traction frame needs to be rotated as a whole, and after the traction direction is changed, because the traction direction is inclined relative to the fixed pulley, it is easy to cause the fixed pulley to get stuck, and it is easy to cause the traction rope to come out of the fixed pulley. Very inconvenient
