Abstract
The present invention relates to regulation tool for installing interlocking intramedullary pin during treating bone fracture and its usage, and belongs to the field of clinical orthopaedic equipment. The present invention features that inner pulling hook; outer push board and arced scale are used in regulating the frame of the original installing tool for reaching its parallel plane relation to the interlocking intramedullary pin. The present invention makes the small locking pin of the interlocking intramedullary pin easily locked into the hole accurately to shorten the time of surgical operation and raise success rate of surgical operation.
Description
Patent of the present invention relates to is a kind of treatment fracture patient when doing the medullary cavity internal fixation and using interlocking (with lock, intersect) intramedullary needle, adjustment instrument and using method thereof that fixing interlocking intramedullary nail is installed.Belong to clinical orthopaedics medical apparatus and instruments instrument class.
Known to the inventor, the fixing interlocking intramedullary nail of each manufacturer production of home and abroad has several different methods in the erecting tools design at present: as sight method, infra-red method, magnetic force positioning mode, endoscope's direct-view method.The purpose of these methods is the little locking nails of fixing interlocking intramedullary nail of packing into accurately in order to guarantee to perform the operation, and it is to realize this purpose by the frame on the erecting tools.This little locking nail need penetrate medullary cavity from a side of skeleton, wears the locking nail hole on the middle fixing interlocking intramedullary nail, and passes from the opposite side of skeleton.The effect of little locking nail is that skeleton and fixing interlocking intramedullary nail are fixed into one, prevents that the two ends rotation of fractured bones and displacement are to reach the purpose of treatment.Can usually occur little locking nail in actual applications installs unsuccessful, this is owing to being out of shape between the erecting tools frame outside appearance after fixing interlocking intramedullary nail is in the medullary cavity of packing into and the pulp cavity, lose parallel, plane relation, cause 1, the locating rack in the erecting tools can not aim at fixing interlocking intramedullary nail, boring back locating rod can not be pushed down on fixing interlocking intramedullary nail; 2, because locating rod is not pushed down fixing interlocking intramedullary nail, can not correct parallel, plane relation between fixing interlocking intramedullary nail and the erecting tools frame; 3, the locking nail hole Cheng Jiao of little locking nail and fixing interlocking intramedullary nail.Make little locking nail can not accurately insert in the locking nail hole of fixing interlocking intramedullary nail, cause operating time to prolong, repeatedly cause iatrogenic fracture and repeated multiple times to throw according to deleterious X ray (because of the doctor have to insert little locking nail under X line perspective) in boring on the skeleton.
The purpose of patent of the present invention is a kind of adjustment instrument and using method thereof that fixing interlocking intramedullary nail is installed of design.This method is on the basis of original erecting tools, the adjustment instrument that increase is made up of interior drag hook, outer pushing plate and camber scale, to reach parallel, the plane relation that when fixing interlocking intramedullary nail is installed, recovers between fixing interlocking intramedullary nail and the erecting tools frame, use the positioning action of sight accurately, method is directly perceived, simple and practical, only need throw according to X line several times, be recovered to get final product with parallel, plane relation between the erecting tools frame to determine fixing interlocking intramedullary nail.
Patent of the present invention is by interior drag hook, outer pushing plate and camber scale are formed, its method of work is as follows: earlier fixing interlocking intramedullary nail and original erecting tools are installed, operation is inserted fixing interlocking intramedullary nail in the medullary cavity, the sight locating rack is installed on frame, guarantee that locating rack is perpendicular to the limbs body surface, look locating rack and be positioned at limbs body surface center line left or right situation decision installation drag hook or outer pushing plate, and the camber scale is positioned on the limb skin surface, vertical limbs X line is thrown and is shone, observe fixing interlocking intramedullary nail in the image in pulp cavity the position and with locating rack on the relation of locating hole, and and scale on scale relation, after reading the scale on the scale, this adjusts interior drag hook or outer pushing plate tool, so that the scale of fixing interlocking intramedullary nail projection is corresponding on the locating hole on the locating rack and the scale, throws once more according to the X line and confirm that locating hole on the locating rack and fixing interlocking intramedullary nail overlap a line and get final product.To skeleton hole along locating hole with drill bit this moment, bores and should touch fixing interlocking intramedullary nail after saturating, inserts locating rod and be pressed on the fixing interlocking intramedullary nail, and then insert little locking nail and promptly be easy to, and the installation that little locking nail is all inserted the back fixing interlocking intramedullary nail is promptly accused and finished.
Below in conjunction with description of drawings embodiment:
Accompanying drawing 1 fixing interlocking intramedullary nail is installed adjustment instrument view.
Accompanying drawing 2 fixing interlocking intramedullary nails are installed adjustment instrument user mode sketch map.
As shown in Figure 1: 1 is fixing interlocking intramedullary nail and erecting tools thereof, and 2 is the erecting tools frame, and 3 is locating rack, and 4 is interior drag hook, and 5 is outer pushing plate, and 6 is the camber scale.
As shown in Figure 2: earlier fixing interlocking intramedullary nail and erecting tools 1 thereof are installed, locating rack 3 is placed on the erecting tools frame 2, then interior drag hook 4 or outer pushing plate 5 also are placed on the erecting tools frame 2, again the camber scale is placed on the limbs body surface, throw according to the X line and determine locating hole on fixing interlocking intramedullary nail and the locating rack and camber scale three's relation, adjust interior drag hook 4 or outer pushing plate 5 and make the locating hole on fixing interlocking intramedullary nail and the locating rack overlap on the line and can hole.
Claims (5)
1, a kind of adjustment instrument and using method thereof that fixing interlocking intramedullary nail is installed is characterized in that: the adjustment instrument that drag hook, outer pushing plate and camber scale are formed in using is used for recovering the method for parallel, the plane relation between fixing interlocking intramedullary nail and the former erecting tools frame.
2, the adjustment instrument and the using method thereof of installation fixing interlocking intramedullary nail as claimed in claim 1 is characterized in that: the profile of interior drag hook, outer pushing plate can be different shapes such as camber, triangle, circle.
3, the adjustment instrument and the using method thereof of installation fixing interlocking intramedullary nail as claimed in claim 1, it is characterized in that: the effect of interior drag hook, outer pushing plate is the position of adjusting the former erecting tools frame of fixing interlocking intramedullary nail, makes it recover parallel, plane relation with fixing interlocking intramedullary nail.
4, the adjustment instrument and the using method thereof of installation fixing interlocking intramedullary nail as claimed in claim 1 is characterized in that interior drag hook, outer pushing plate and camber scale made by rigid material.
5, the adjustment instrument and the using method thereof of installation fixing interlocking intramedullary nail as claimed in claim 1 is characterized in that: interior drag hook, outer pushing plate and camber scale promptly can use at the left and right side of suffering from limb, also can use in the front and rear direction of suffering from limb.
