Abstract
The utility model relates to a gear and rack double traction cervical vertebra and lumbar vertebra distracter, which comprises a fixing support (1), a traction device (2), a jaw combination band (3), and a traction rope (4). The traction device is a gear and rack transmission structure, dual-gear-driven rack traction. The gear is a stalk-gear (7), with the gear stalk hole (5) connected with the traction rope (4), and pulled the traction rope (4) to make the stalk-gear (7) rotate. The stalk-gear (7) drives the rack (8) to move upward to achieve the cervical vertebra and lumbar vertebra traction. The utility model has simple structure, small size, with small operating force and forceful traction power, so the utility model is suitable for self operation. The utility model is a cervical vertebra and lumbar vertebra distracter for both therapy and health purpose, which can be used for self traction.
Description
One, affiliated field
This utility model relates to a kind of neck, lumbar tractor, especially can be by the patient from the two drawing-type necks of the rack-and-pinion of line operate, lumbar tractor.
Two, background technology
At present, in existing neck, lumbar tractor, its haulage gear mainly contains the gear type traction, the traction of gear teeth stripe shape, pulley type traction, nut-screw type traction etc., gear type, gear teeth stripe shape, pulley type, nut-screw type all are complex structures generally, and volume is bigger, and suitable hospital uses, even if household type, also there are problems such as complex structure, volume are big, operation inconvenience.The Chinese patent patent No. is that CN96221367.5 relates to a kind of cervical vertebra tractor problems such as just the existence making is comparatively complicated, volume is big, operation also not too makes things convenient for.
Three, summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and volume is little, and is easy to operate, operating force little and neck, the lumbar tractor of traction great efforts, and this is a kind ofly to collect treatment and be the neck of one, lumbar tractor with health care.
The purpose of this utility model is achieved in that
In the traction apparatus of gear, rack gear structure, mesh with the bidentate wheel and rack, gear is band handle gear, to obtain big moment, on the gear handle, connect pulling rope, traction apparatus is hung on the fixed support, and traction apparatus hangs up properly lower jaw and encloses assemblage zone or waistline assemblage zone, then can draw neck, lumbar vertebra.Lower jaw is enclosed assemblage zone to the patient or the waistline assemblage zone is fastened, both hands pulling pulling rope, and pulling rope driven gear handle makes the gear rotation, and the gear driven tooth bar moves, and reaches the purpose of traction neck, lumbar vertebra.Effect of the present utility model is: the patient can draw neck, lumbar vertebra voluntarily, and the operation traction force is little and pull strength is big and easy to operate, can the oneself control, and retractor structures is simple, and volume is little.
Four, description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is that illustration is implemented in this utility model traction.
Fig. 2 is this utility model structure and topography view.
1. fixed supports among Fig. 1,2 traction apparatuss, 3. jaw encloses assemblage zone, 4. pulling rope.
4. pulling ropes among Fig. 2,5. gear delthyrium, 6. gear shaft, 7. band handle gear, 8. tooth bar, 9. tooth bar hook, 10. traction apparatus frame, 11. traction apparatus hanging holes.
Five, the specific embodiment
In Fig. 1, this utility model by fixed support (1), traction apparatus (2), jaw enclose assemblage zone (3), pulling rope (4) is formed, earlier traction apparatus (2) is hung on the towing bracket (1), again jaw is enclosed and hang over (2) on the traction apparatus after assemblage zone (3) ties up to patient's lower jaw, patient's both hands are held pulling rope (4) tractive downwards, traction apparatus (2) then upwards draws patient's lower jaw part, reaches the traction to cervical vertebra.Be replaced by the waistline assemblage zone if jaw is enclosed assemblage zone (3), then can draw lumbar vertebra.
In Fig. 2, each fixes a band handle gear (7) on traction apparatus frame (10) by gear shaft (6) respectively in tooth bar (8) both sides, band handle gear (7) and tooth bar (8) engagement, pulling rope (4) is connected with gear delthyrium (5), traction apparatus is fixed in appropriate location, top, patient crown (see figure 1) by traction apparatus hanging hole (11), the patient fastens jaw and encloses assemblage zone, be connected with traction apparatus hook (9), patient's both hands are respectively held a pulling rope (4) tractive downwards, pulling rope (4) drives band handle gear (7) rotation, band handle gear (7) drives tooth bar (8) and moves up, and reaches the purpose to patient's cervical vertebra or lumbar traction.Loosen pulling rope (4), traction apparatus hook (9) moves down with human body gravity, and band handle gear (7) has been got back to original position again with tooth bar (8).
Claims (1)
1, the two drawing-type necks of a kind of rack-and-pinion, lumbar tractor, by fixed support (1), traction apparatus (2), jaw enclose assemblage zone (3), pulling rope (4) is formed, wherein traction apparatus (2) is the rack-and-pinion drive mechanism, mesh with bidentate wheel and rack (8), gear is band handle gear (7), it is characterized in that: the gear delthyrium (5) of traction apparatus (2) is gone up and is connected two pulling ropes (4), and pulling rope (4) other end is held for the patient and held.
