Prone type cervical correcting device

Abstract

The invention discloses a prone type cervical correcting device which comprises a base, two chest shoulder pads, a chin pad and a forehead pad. The two chest shoulder pads are symmetrically arranged on the base; the two chest shoulder pads, the chin pad and the forehead pad are supported on the base by a chest shoulder pad supporting frame, a chin pad supporting device and a forehead pad supporting device, wherein the chin pad supporting device comprises a rear supporting strip and a front supporting strip; the front supporting strip and the rear supporting strip are articulated with each other; one end of the rear supporting strip is articulated on the base; the other end of the front supporting strip is movably supported in a supporting groove on the base; the supporting groove is formedby a plurality of small grooves arranged in parallel and in a shape matched with the shape of the end of the front supporting strip; the lower end of the chin pad is articulated at the articulated end of the front supporting strip and the rear supporting strip; the chin pad is a concave supporting pad matched with the shape of a human chin; and the forehead pad supporting device comprises a forehead supporting base and a height adjusting mechanism arranged above the forehead supporting base. The invention has the advantages of appropriate force application, comfortable use and good treatmenteffect.

Description

technical field [0001] The invention relates to a stretching tractor for human cervical spine, in particular to a prone cervical spine correcting device. Background technique [0002] At present, the known cervical tractors all have to pull the head by external force to produce cervical traction effect. This kind of cervical tractors have the following disadvantages respectively: 1. The patient's head is in a restrained state during the traction process, making it difficult to self-adjust. 2. The effective traction of the cervical spine by the tractor needs to overcome the weight of the head itself. The traction headgear exerts a large force on the headrest and mandible (the strength of the seat tractor is more than 5 kg), and long-term use may cause iatrogenic mandibular Bone and joint injuries. [0003] In addition, Patent Publication No. CN1965773A once disclosed a cervical and lumbar restoration stretcher, which adopts a dual-purpose seat frame connected by a pin shaft,...

Problems solved by technology

[0002] At present, the known cervical traction devices all have to pull the head by external force to produce cervical traction effect. This type of cervical traction devices has the following disadvantages: 1. The patient's head is in a restrained state during the traction process, and it is difficult to self-adjust

2. The effective traction of the cervical spine by the tractor needs to overcome the weight of the head itself. The traction headgear exerts a large force on the headrest and mandible (the strength of the seat tractor is more than 5 kg), and long-term use may cause iatrogenic mandibular bone and joint injury

But this portable prone position cervical traction device, when it is in use, is to directly adopt the occipital-jaw traction belt to entangle the patient's head and neck, turn the handwheel, and then use the screw nut structure to convert the force applied by the handwheel into an occipital-jaw traction belt cover. Pulling force towards the front, the force is applied in the direction of the front, and the effect is not good. At the same time, if the force is not applied properly, it is easy to cause cervical spine injury
