Abstract
The utility model disclose an inserting angle measuring guide device for thoracolumbar vertebra pedicle screws, and belongs to an auxiliary tool of medical instruments. The inserting angle measuring guide device comprises two sets of barrel plate compound fixed arms connected with each other and a graduated connecting plate with a gap arranged in the middle. The two sets of barrel plate compound fixed arms and the connecting plate are fixed to a whole through fastening screws and nuts. When the inserting angle measuring guide device is used, firstly a sleeve is adjusted and fixed on a protractor of the graduated connecting plate in a corresponding angle according to an angle needed in inserting and fixing pedicle screws through a pointer on the sleeve, then a pedicle screw on one side is inserted and fixed through the sleeve and along the direction of the sleeve, then the fixing positions of the side barrel plate compound fixed arms and the connecting plate are adjusted according to an actual distance between a pedicle screw entrance point and a spine centerline, and the side pedicle screw is inserted and fixed. Besides, the pedicle screws can be fixed at the same time after the angles of two sides and the distances of two sides are fixed.
Description
(1) technical field
This utility model relates to a kind of appurtenance of medical apparatus and instruments, specifically a kind of angular surveying guide instrument of regulating breast pedicle of lumbar vertebral arch nail placing direction.
(2) background technology:
Breast pedicle of lumbar vertebral arch nail is inserted technique for fixing and is widely used in the diseases such as lumbar vertebra compression fracture, breast prolapse of lumbar intervertebral disc, spinal canal stenosis.But insert in the pedicle nail process in operation, depended on the experience of surgical doctor more in the past, determine to insert the angle of pedicle nail by the range estimation mode.Thereby pedicle nail in operation, occurs easily and insert the inaccurate of angle, affect surgical effect, even can again insert pedicle nail, cause the generation of the fixing situation such as insecure of prolongation, the pedicle nail of operating time.
(3) summary of the invention:
Technical assignment of the present utility model is for the deficiencies in the prior art, provides a kind of and inserts the instrument that definite pedicle nail is inserted the angular surveying guiding in the process in pedicle of vertebral arch.
The technical scheme that its technical problem that solves this utility model adopts is:
This breast pedicle of lumbar vertebral arch nail is inserted the angular surveying guide instrument, comprise two groups of compound fixed arms of cylinder plate and a graduated connecting plate, wherein every group of compound fixed arm of cylinder plate forms by angle board and sleeve fixed combination, two groups of compound fixed arms of cylinder plate pass through trip bolt by nail hole and connecting plate on the angle board respectively, nut is fixed, and allow two groups of compound fixed arms of cylinder plate to carry out move left and right with adjustable range along the breach on the connecting plate, the upper end profile of sleeve is triangle, leg-of-mutton tip forms pointer, and this sleeve can be respectively be rotated and carries out angular surveying and fix along the protractor on the angle board, sleeve on the compound fixed arm of cylinder plate is fixed by clamp nut in bush whorl bar position with angle board respectively, and sleeve can be respectively take its threaded rod as axis of rotation, along the protractor direction rotation on the angle board, the central point of bush whorl bar is the center of circle of the protractor of angle board respectively.Angle board is a straight plate with protractor, and protractor is marked with angle, is that 0 degree is to 40 degree, take 5 degree as the interval.Angle board respectively has up and down a circular hole, and its following circular hole and bush whorl bar are fixed, and the top circular hole is fixed by screw and connecting plate.The protractor of left side angle board is in the left side of plate, and the protractor of the right angle board is on the right side of plate.During use the pointer of sleeve is fixed on the angle of being scheduled to when inserting pedicle nail, by sleeve, inserts pedicle nail along its direction.
Connecting plate is marked with scale, and take its center as 0, both sides are respectively 1,2,3, and unit is cm.Be rectangular indentation in the middle of the connecting plate, a compound fixed arm of plate of both sides can be inserted a little along the connecting plate breach, according to pedicle nail the fixing point of fixing itself and connecting plate with the distance adjustment of spinal column mid point.Also the compound fixed arm of cylinder plate and connecting plate can be pulled down in addition, use separately.

(5) specific embodiment:
Insert the angular surveying guide instrument and do following detailed explanation below in conjunction with accompanying drawing 1,2,3,4,5,6,7,8,9,10 pairs of breast pedicle of lumbar vertebral arch nails of the present utility model.
As shown in Figure 1, breast pedicle of lumbar vertebral arch nail of the present utility model is inserted the angular surveying guide instrument, comprises two groups of compound fixed arms of cylinder plate (6 and 8 are fixed as one group of compound fixed arm of cylinder plate, 7 and 9 is fixed as the compound fixed arm of another group cylinder plate) and a graduated connecting plate.Sleeve and angle board on every group of compound fixed arm of cylinder plate are fixed by clamp nut in bush whorl bar position, and sleeve take its threaded rod as axis of rotation, can carry out angular surveying along the protractor direction rotation of angle board and fix.
Two groups of compound fixed arms of cylinder plate are fixed by trip bolt, nut by the nail hole on the angle board and connecting plate respectively, and allow two groups of compound fixed arms of cylinder plate to carry out move left and right with adjustable range along the breach on the connecting plate.
At first inserting fixing needed angle by the pointer on the sleeve according to pedicle nail during use is fixed to the sleeve debugging on the corresponding angle of protractor of angle board, then by sleeve and carry out a side pedicle nail along its direction and insert fixing, then according to actual range between pedicle nail entry point and the midspinal line, gear shift is carried out the offside pedicle nail and is inserted fixing the fixed position of the compound fixed arm of side neck plate and connecting plate.Also but both sides carry out that angle is fixed, distance carries out simultaneously pedicle nail after fixing and fix.After its sleeve is made semicircle tubular reason and is that pedicle nail carries out angular surveying, can keep in the isogonal situation of pedicle nail, remove this breast pedicle of lumbar vertebral arch nail and insert the angular surveying guide instrument, and do not affect operation technique.
The advantage of this covering device is: (1) is according to the characteristics of different segment breast pedicle of lumbar vertebral arch angle, insert required angle according to pedicle nail and can accurately insert pedicle nail, the postoperative complication that minimizing brings because of when operation range estimation angular error shortens operating time.(2) owing to the symmetry of human body bilateral pedicle of vertebral arch, then the pedicle nail that can insert first a side is measured by the yardstick at connecting plate place, can find fast and accurately pedicle of vertebral arch and the entry point of offside, improves accuracy and the symmetry of operation entry point.(3) the cylinder compound fixed arm of plate and connecting plate fixed form are simple, can assemble and take apart use according to the personal like, do not affect result of use.
