Disk cover positioning cervical traction frame

Abstract

The invention relates to the technical field of medical apparatuses and instruments, and particularly relates to a disc-cover location type cervical traction frame which comprises a main shaft, a main gear, a gasket, a locating hole, a lug, a handle cylinder, a drive wheel, a locating disc, a chain, an auxiliary wheel axle, an auxiliary gear, an upright, a base, a baffle plate, a suspension frame and other parts, wherein the locating disc is disc-shaped, a shaft hole is formed in the center of the locating disc, and a horizontal through hole is formed in a shaft frame and is just opposite to the shaft hole horizontally. A plurality of locating holes uniformly distributed along the circumference of the locating disc are formed in the edge of the left side wall of the locating disc. A horizontally-arranged cylinder shaft is arranged at the edge of the left side wall of the drive wheel, and an annular groove is formed in the outer side wall of the cylinder shaft. According to the disc-cover location type cervical traction frame, a patient conveniently, autonomously and accurately locates a pillow-jaw band, the pillow-jaw band can be enabled not to deviate, and good stability is achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a disk cover positioning type cervical vertebra traction frame. Background technique [0002] The application number is 200820187247.9 "cervical vertebra traction frame" comprises parts such as cross bar, groove, occiput and jaw strap and hanging ring, puts into the groove of cross bar to realize the positioning of occiput and jaw strap through the hanging ring of occiput and jaw strap. There are following defects in such technical features: [0003] 1. Precise positioning cannot be achieved. There must be a large interval between the grooves of the crossbar, so that the partition between adjacent grooves has a certain strength to withstand the lateral pressure generated by the hanging ring, and this interval makes the hanging ring in the horizontal direction. The horizontal displacement length on the bar must be an integral multiple of the interval, which makes the...

AI Technical Summary

Problems solved by technology

[0003] 1. Unable to achieve precise positioning

There must be a large interval between the grooves of the crossbar, so that the partition between adjacent grooves has a certain strength to withstand the lateral pressure generated by the hanging ring, and this interval makes the hanging ring in the horizontal direction. The length of the horizontal displacement on the bar must be an integral multiple of the interval, which makes the horizontal position of the occiput-maxillary belt impossible to accurately locate

[0004] 2. It is impossible to adjust the horizontal position of the occiput and jaw strap conveniently

This is very inconvenient when the patient's head is already in the occipital-maxillary strap, and it is even more difficult if the patient is asked to adjust to their own comfort because it requires the patient to reach over the top of the head to see the eyes. Operate from an invisible location

[0005] 3. Poor stability of the occipital and maxillary belt after positioning

Since the occiput-chin strap is positioned by the hanging ring on its top, and the hanging ring is in the groove of the cross bar, although the upper beam of the hanging ring cannot move along the longitudinal direction of the cross bar, it can move along the transverse direction of the cross bar. The lateral movement of the hanging ring will cause the deviation of the occipital and maxillary belt, which will cause discomfort to the patient and affect the effect of the treatment
