Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described further.
See accompanying drawing 1-4, this intervertebral disc function method localised puncture frame disclosed in the utility model, comprises locating hole 1, sleeve pipe hold-down nut 2, puncture casing 3, cross bar 4, vertical pole 5, contiguous block 6, fixing card 7, cross bar slideway 8, vertical pole slideway 9, vertical pole set bolt 10, cross bar set bolt 11, sleeve 12.
Contiguous block is respectively arranged with a through slideway along on its width and length direction, i.e. cross bar slideway and vertical pole slideway, in two planes arranged before and after two slideways are positioned at, and two slideways are vertically arranged, and cross bar and vertical pole are inserted in slideway respectively.Contiguous block is provided with clamping screw, clamping screw matches with two slideways respectively, and namely slideway comprises cross bar slideway and vertical pole slideway, and locking nut comprises cross bar clamping screw and vertical pole clamping screw, cross bar clamping screw is corresponding with cross bar slideway, and vertical pole clamping screw is corresponding with vertical pole slideway.Cross bar clamping screw is arranged on the contiguous block sidewall of cross bar slideway side, its precession and back-out, and control the locking of cross bar and loosen, vertical pole in like manner.
Cross bar and vertical pole are respectively arranged with the rule for locating.By controlling clamping screw, regulating the relative position of cross bar and vertical pole, carrying out precise positioning by the rule on its surface.
Cross bar is provided with two locating holes, is fitted with sleeve pipe hold-down nut in locating hole, puncture casing is arranged on sleeve pipe hold-down nut.The top of the excircle of locating hole is provided with angle measuring scale, sleeve pipe hold-down nut is provided with a sleeve be integrated with it, this sleeve is provided with a through hole, sleeve is inserted in locating hole, puncture casing is inserted in the through hole of sleeve, by rotating sleeve, determine the rotational angle of puncture casing.
The bottom of vertical pole is provided with fixing card by connector, and fixing cartoon is crossed connector and is fixed on operation table frame.For being flexibly connected between vertical pole bottom with fixing card upper surface, namely can rotate around connector between vertical pole and fixing card.When plan puncture intercalated disc and crossbar be not or not a plane, need vertical pole to rotate, so that puncture needle points to intend the intervertebral space that punctures.Puncture casing is the guiding channel of puncture needle; After puncture angle mixes up, fix puncture casing with sleeve pipe hold-down nut.
When implementing intervertebral disc puncture, puncture supporter is scheduled on the other crossbeam of operation table with fixing fixing, measure intervertebral disc according to C arm machine fluoroscopic image and intend the distance of point of puncture on vertical pole between subpoint and cross bar, the puncture angle that intervertebral disc intends point of puncture is measured according to preoperative CT sheet, try to achieve intervertebral disc on cross bar according to trigonometric function and intend the length that point of puncture projects to the Distance geometry puncture needle of puncture needle, then the position into nail angle and entry point is adjusted, grasp the length of puncture needle, thrust along puncture casing, C arm machine observes puncture effect.
Operating process of the present utility model is summarized as follows:
Patient lies prone position, with C arm machine Kirschner wire Fluoroscopy location, depicts waist 4/5 intervertebral space position at patient's lower back and right side, and the position that reaches intended by puncture needle, i.e. point of care (position, side: 1/3 intersection intervertebral space mid point after in intervertebral space; Normotopia: pedicle of vertebral arch medial border plane intervertebral space mid point on the right side of waist 4.) sterilize in visual area, paving operation towel.To fix and fix on crossbeam on the right side of operating-table, position is relative with waist 4/5 intervertebral space side, and vertical pole is placed on the right side of lumbar vertebra along intervertebral space, and cross bar is placed in lower back, relative with intervertebral space, locking junction button and fixing card.Vertical pole measures the distance between point of care and cross bar.Preoperative CT sheet measures puncture needle angle, i.e. point of care and waist 5 superior articular process outer rim line and the sagittal angle of body.At this moment, on the cross-section axial plane of lumbar vertebra 4/5 intercalated disc, the triangle that virtual is had.Two right-angle sides are the line that point of care arrives cross bar, and the line between point of puncture and locating hole to the projection of point of care on cross bar, puncture needle is hypotenuse.According to trigonometric function rule, calculate the length of base and hypotenuse.Adjusting locating hole to the projection pitch of point of care on cross bar is the length on base, locking junction button, according to the direction of CT institute measuring angle adjustment trocar sleeve, tightens hold-down nut.Choose the puncture needle that hypotenuse length matches to thrust along trocar sleeve, during to hypotenuse length, C arm machine observes the position of puncture needle.After position suitable, proceed next step operation.
