The purpose of this utility model provides a kind of lumbar tractor flexible and convenient to use, evident in efficacy of adjusting.
Scheme of the present utility model is adjusted arm, binder etc. and is formed by support, ratchet wheel frame, traction table lead screw, upper and lower towing plate, guideway, horizontal leading screw, top back, top back, its construction features is that the rear side at support is provided with ratchet wheel frame, the middle part of traction table lead screw is provided with ratchet and axle journal, and traction table lead screw is installed on the pin-and-hole on ratchet support top by axle journal.The both sides up and down of support are provided with towing plate up and down, and the rear side fixed installation of towing plate is two adjusting nuts up and down, and two nuts are shaped on left and right screw thread respectively, and coupling is installed in the upper/lower terminal of traction table lead screw.The left and right sides that is positioned at towing plate is shaped on guideway up and down respectively, and axis of guide middle part is fixed on the both sides of support, and two ends are installed in the guideway respectively.Horizontal leading screw is equipped with in the inboard of support, and laterally leading screw is provided with the top back and adjusts arm, and the front end of adjusting arm is equipped with the top back, and the front side of towing plate is equipped with two respectively and is tightened band up and down.
The utility model has the advantages that: novel, reasonable in design, cost is low, good effect, install and use flexible, can be free movable during patient treatment, do not influence traction effect.
Be described further below in conjunction with accompanying drawing
Fig. 1 is the retractor structures sketch map
Fig. 2 is the traction apparatus side view
The rear side of figure medium-height trestle 1 is equipped with ratchet wheel frame, ratchet wheel frame is made up of two clamping plates 14 up and down, the bottom of two clamping plate is fixed on the support with bolt 15, the upper end is shaped on pin-and-hole 13, the middle part of traction table lead screw 3 is provided with ratchet and axle journal, ratchet 23 is fixedly mounted on the leading screw by flat key 22, the two ends up and down of traction table lead screw are shaped on left and right sides screw thread respectively, leading screw is installed on the pin-and-hole of ratchet wheel frame upper end by axle journal, friction plate 32 is equipped with in the both sides of ratchet 23, the cylindrical of ratchet is provided with ratchet sleeve 20, and handle 21, moving tooth 24 are housed on the ratchet sleeve.Moving tooth is by moving tooth axle 31, spring 25, and axle sleeve 26 is regulated medicated cap 27 and is formed, and moving tooth axle sleeve lower end is welded on the ratchet sleeve, and the upper end is shaped on locating slot, and the moving tooth axle is installed in the axle sleeve, and holddown spring is equipped with in the upper end, and moving tooth axle lower end is shaped on and gets a tooth pulled out, and the upper end is shaped on the adjusting medicated cap.Be shaped on alignment pin under the medicated cap.Towing plate 5 is equipped with at the two ends up and down that are positioned at leading screw, following towing plate 10, and top nut 4, on the towing plate, two nuts were shaped on left and right screw thread and traction table lead screw two ends coupling installation up and down respectively about lower nut 9 was fixed on respectively.The left and right sides of towing plate is shaped on left guideway 2 up and down, and right guideway 6, two axis of guides 11 middle parts are fixed on the both sides fulcrum of support, and axis of guide two ends are installed in respectively in the guideway, and the front side of towing plate is equipped with two respectively and is tightened band.
Be provided with horizontal leading screw 8 in the inside groove of Fig. 2 medium-height trestle 1, laterally leading screw is installed on the both sides axle sleeve 12 of support, the right-hand member of leading screw is provided with regulating handle 28, laterally the two ends, the left and right sides of leading screw are shaped on left and right screw thread respectively, left side nut 19, right nut 29 is installed in the two ends of leading screw respectively, and the front side of two nuts is installed with two top backs with pivot pin 18 respectively and adjusts the front side of arms 17, two adjustment arms and with pivot pin top back 16 is housed.
This utility model is to utilize mechanics principle to adjust the physiology orphan degree that waist pushes away, and progressively alleviates whole shape, reaches therapeutic effect, and its operation principle is:
1, pulls traction handle and play the effect that separates pressurization, intervertebral space is increased, create conditions for vertebral pulp resets.
2, rotate horizontal leading screw, make the extruding lumbar vertebra, recover the normal physiological radian.
3, fixing waist, protection pathological interspinal dish do not cause damage because of movable.
During use, the binder upper end is fixed on side of body bow portion, the lower end is fixed on the bone hip, and the top back is aimed at position, the 3rd waist pushed section, and the adjusting of towing plate can be adjusted to the desired position with the moving tooth rotation, pull ratchet handle, moving tooth is just stirred ratchet, drives traction table lead screw and rotates, and towing plate is under the rotation of positive and negative nut, stretch or contraction, reach the optimum efficiency of traction.The adjusting of top back be rotation regulating handle 28, two backs adjust arm under the rotation of positive and negative nut with top back jack-up or even up, reach best therapeutic effect.This utility model is lumbar vertebra fixedly, not because of making left rotation and right rotation and preceding bent action increases the load of intervertebral disc, thereby alleviates pathological interspinal dish pressurized, helps inflammation to disappear and mitigation symptoms.
