Description
Technical field
This utility model relates to medical instrument field, particularly relates to a kind of orientation tool of fracture of femoral neck hollow nail.
Background technology
Fracture of femoral neck has become comparatively common orthopaedics illness at present, spends a large amount of human and material resources and financial resources to carry out the treatment of being correlated with every year for this reason.At present, usually can adopt the conservative Therapeutic Method such as to lie up for imperfection fracture of femoral neck, and without shift-type complete fracture and shift-type fracture, except non-patient has obvious surgical contraindication, all should operative treatment be considered.For complete shift-type fracture of femoral neck, owing to there is the probability of the bad and ischemic necrosis of femoral head of higher healing of femoral neck fracture, whole coxa substitution or half hip replacement are then considered to ideal method.And open reduction and Kirschner wire fixation for comparatively young neck of femur without shift-type and transposition of partial stable type fracture of femoral neck and the gerontal patient without displacement stable type fracture of femoral neck, remain ideal therapeutic choice.
Fracture of femoral neck is cut or closed reduction internal fixtion comprises multiple method, and many forcing screw fixed fracture of femoral neck are methods of main promotion at present, and that wherein commonly uses has AO compression screws, Asnis nail etc.The advantage of cannulated compression screw has: fracture end can obtain good plus-pressure; Three pieces of screws fixedly have very high intensity and anti-torsion ability; Operation technique is easy, operation wound is little.Due to the pressurization between fracture site and strong fixing, improve union of fracture rate.The curative effect of fracture of femoral neck many cannulated compression screw internal fixtion is relevant with many factors, as the operating technology etc. of degree, patient age and operator that the degree of neck of femur displacement, waiting time of performing the operation, the confession of neck of femur blood destroy, wherein the operating technology of operator is very crucial, comprise the reset of fracture, spatial distribution, the angle of screw, the quantity of screw and driving depth that hollow screw distributes in neck of femur, these all directly to determine after fracture of femoral neck internal fixtion intensity at once, the prognosis for the treatment of of femoral neck fracture is played an important role.But, at present clinically great majority for fracture of femoral neck line space heart Pinning, preoperative location is often made up of simple and easy object of reference, as Kirschner wire etc., a "ball-park" estimate preoperatively can only be made with these class methods location, easily there is error when beating guide pin in operation, to take unnecessary iatrogenic injury to patient, also extend operating time.
So the orientation tool inventing a kind of simple and practical fracture of femoral neck hollow nail is the hope of orthopedist.
Summary of the invention
In order to solve the problem, the purpose of this utility model is the orientation tool providing fracture of femoral neck hollow nail, by using this orientation tool, the inserting needle direction determining hollow nail can be convenient to, thus improve operation degree of accuracy, reduce patient's damage, improve procedure efficiency.
In order to realize above-mentioned object, this utility model have employed following technical scheme:
An orientation tool for fracture of femoral neck hollow nail, is characterized in that: comprise mobile jib, the first secondary bar, the second secondary bar and inserting needle bar; Described first secondary bar and the second secondary bar all indicate scale, and the middle part of the first secondary bar and the second secondary bar is all fixed on mobile jib, and the first secondary bar and the second secondary bar are parallel to each other and all perpendicular with mobile jib; The end of described inserting needle bar is slidably arranged on the first secondary bar, and be provided with angle demodulator between inserting needle bar and the first secondary bar, the angle between inserting needle bar and the first secondary bar is limited between 35 ° ~ 40 ° by described angle demodulator.
As preferably, the cross section of described mobile jib is the square that the length of side is 5mm.
As preferably, the movable end of described inserting needle bar is also connected with longitudinally secondary bar, longitudinal secondary bar is spatially perpendicular to mobile jib and the first secondary bar; Longitudinally secondary bar is marked with scale, longitudinally secondary bar is also provided with two auxiliary bars of inserting needle, and the equal longitudinal sliding motion in middle part of two auxiliary bars of inserting needle is arranged on longitudinal secondary bar; When femur is due to external force deformation, when entry point deviation is excessive, by the two auxiliary bars of inserting needle that slide, in order to measure the scope of Fracture of femur point, doctor regulates the inserting needle direction of hollow nail by measuring numerical value.
This utility model adopts technique scheme, and the orientation tool of this fracture of femoral neck hollow nail can be convenient to the inserting needle direction determining hollow nail, thus improves operation degree of accuracy, reduces patient's damage, improves procedure efficiency.During use, patient is in the shape that dosses, the mobile jib of orientation tool is parallel to femoral axis to arrange, first secondary bar and the second secondary bar are respectively used to the femoral width measuring different parts, slided by measurement data and adjust inserting needle bar, after determining inserting needle boom end (i.e. entry point), by the direction (i.e. inserting needle direction) of angle demodulator determination inserting needle bar.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.
As shown in Figure 1, the orientation tool of this kind of fracture of femoral neck hollow nail, comprises mobile jib 1, first secondary bar 2, second secondary bar 3 and inserting needle bar 4.The cross section of described mobile jib 1 is the square that the length of side is 5mm, and the first secondary bar 2 and the second secondary bar 3 all indicate scale, and the middle part of the first secondary bar 2 and the second secondary bar 3 is all fixed on mobile jib 1, and the first secondary bar 2 and the second secondary bar 3 are parallel to each other and all perpendicular with mobile jib 1; The end of described inserting needle bar 4 is slidably arranged on the first secondary bar 2, is provided with angle demodulator 5 between inserting needle bar 4 and the first secondary bar 2, and the angle between inserting needle bar 4 and the first secondary bar 2 is limited between 35 ° ~ 40 ° by described angle demodulator 5.The movable end of described inserting needle bar 4 is also connected with longitudinally secondary bar 6, longitudinally secondary bar 6 is spatially perpendicular to mobile jib 1 and the first secondary bar 2; Longitudinally secondary bar is marked with scale, and the equal longitudinal sliding motion in middle part longitudinally secondary bar being also provided with two auxiliary bars of inserting needle, 7, two auxiliary bars of inserting needle is arranged on longitudinal secondary bar; When femur is due to external force deformation, when entry point deviation is excessive, by the two auxiliary bars of inserting needle that slide, in order to measure the scope of Fracture of femur point, doctor regulates the inserting needle direction of hollow nail by measuring numerical value.
Comprehensive technique scheme, the orientation tool of this fracture of femoral neck hollow nail can be convenient to the inserting needle direction determining hollow nail, thus improves operation degree of accuracy, reduces patient's damage, improves procedure efficiency.During use, patient is in the shape that dosses, the mobile jib 1 of orientation tool is parallel to femoral axis to arrange, first secondary bar 2 and the second secondary bar 3 are respectively used to the femoral width measuring different parts, slided by measurement data and adjust inserting needle bar 4, after determining inserting needle bar 4 end (i.e. entry point), by the direction (i.e. inserting needle direction) of angle demodulator determination inserting needle bar 4.
