Cranial fixation retractor and method of using the same

Abstract

The invention relates to a traction apparatus, and in particular to a skull fixation tractor and a using method thereof. The fixation tractor comprises a seat and a stand which is arranged at the front side of the seat, wherein a driving main shaft and a driving connecting rod are arranged on the stand; a pedal is connected to the driving connecting rod; a driven main shaft is arranged at the lower side of the driving main shaft in a parallel mode; a driving gear and a guide disc are sleeved on the driving main shaft; a driving roller is connected to the driven main shaft in a sliding mode; a driven gear, which is meshed with the driving gear, is fixedly arranged at one end of the driving roller; a pre-tightening spring, which is used for applying axial pre-tightening force to the driven gear, is sleeved on the driven main shaft; a pull rope is wound on the driving roller; the other end of the pull rope is inserted in a part above the seat and a head cover is fixedly connected to the other end of the pull rope; and the head cover comprises a base which is erected on shoulders and a traction seat which is arranged on the base. The skull fixation tractor provided by the invention has the beneficial effects that the skull fixation tractor can be conveniently operated by a single person, the skull fixation tractor can effectively prevent the upper part of a user's body from leaning and the skull fixation tractor can guarantee stability of traction displacement and a traction direction, and the like.

Description

Technical field [0001] The invention relates to a traction equipment, in particular to a head fixation retractor and a method of use thereof. Background technique [0002] The existing neck traction pulls the headgear through the lifting force of the pull rope, and pulls the chin and the back of the head upward. The driving method of the pull rope adopts manual rotation or motor rotation. This operation method requires manual operation. During manual operation, the upper body is prone to tilt or twist. When the upper body is tilted or twisted, it is easy to cause the cervical spine traction direction to deviate, even if it is very The slight traction displacement and the change of the traction direction can easily cause considerable damage to the cervical spine. Moreover, the existing traction method of this type is to directly put the headgear on the neck and use the headgear to wrap the chin and back of the head. However, this traction method cannot locate the shoulders and ca...

AI Technical Summary

Problems solved by technology

The driving method of the pull rope is manual rotation or motor rotation. This operation method requires manual operation. During manual operation, the upper body is prone to tilt or twist, and when the upper body tilts or twists, it is easy to cause the direction of cervical traction to deviate. Minor traction displacement and traction direction changes can easily cause considerable damage to the cervical spine

Moreover, the existing traction method of this type is to directly put the headgear on the neck, and use the headgear to cover the lower jaw and the back of the head, but this kind of traction method cannot locate the shoulders, and cannot ensure that the position of the shoulders is consistent with the stretching direction of the head sex
