Description
Technical field
This utility model relates to technical field of medical instruments, especially relates to a kind of external dynamic hip screw guider.
Background technology
At present, human society enters aging, and neck of femur and intertrochanteric fracture of the femur are old people's common frdquently encountered diseases.It is fixedly current conventional operation method that intertrochanteric fracture of the femur is used in DHS, and one of key operation of operation is to insert location guide pin, and it has determined position and the direction of screw in neck of femur, and the success or failure of operation are played an important role.But because neck of femur anatomical structure is special, in Different Plane, there is collodiaphyseal angle and top rake, and position deeply, hidden, make to locate correctly inserting of guide pin and have certain difficulty.When clinical internal fixation treatment neck of femur and intertrochanteric fracture of the femur, all need first to insert guide pin location.Normally with doctor's clinical experience, carrying out guide pin inserts, after each inserting needle, all need to adopt C arm machine to have an X-rayed to check whether guide pin enters puts in place, but conventional because its entry point is upper or lower skew, top rake and collodiaphyseal angle grasp are bad, causing locating guide pin can not correctly insert.
In recent years, many scholars have designed some operating theater instruments, have even applied computer assisted navigation system.In the similar apparatus of design principle, the localizer of the design such as Wu Lin, fixed point puncture needle need puncture to femoral head central point, and the patients with fracture of neck reduction of the fracture needs to maintain lower limb inward turning position more, now, this point, by acetabular bone embedding, is difficult for being punctured to, and this point from abdominal cavity and thigh portion nervus vasculairs close to, easily stab these vital tissues.Yu is superfine to be used for computer navigation to fix in hollow nail, has advantages of and improves the precision of operation, the error that can avoid mechanical guiding device, shortening operating time.But this system price is expensive, at basic hospital, be difficult at present universal.
Use conventional DSH angle guideline, unless operator's straightforward manipulation under X-ray examination pierces after guide pin as finds on the upper side or on the lower side, need to take out guide pin in art, after adjustment, again pierce, as dissatisfied, need repetitive operation again.Cause repeatedly inserting needle repeatedly, to patient, bring iatrogenic infringement, repetitious C arm machine perspective is brought radiation injury to patient and medical personnel.
For above-mentioned technical problem, notification number is that the patent of CN202146359U discloses " a kind of Multifunctional dynamic hip screw guider ", it comprises substrate and guide pad, angle between guide pad and substrate is 130 ° or 135 °, in guide pad, be provided with two above and be parallel to each other guiding needle tracks, guide pad is draw-in groove drawing and pulling type structure, during use, need and under femoral greater trochanter, make the otch of long 4 to 6 centimetres by patient's anesthesia, again substrate is close to lateral side of femur face, utilize any one guiding needle track to pierce guide pin, fluoroscopic image according to C type arm X-ray machine in normotopia, select corresponding guiding needle track to pierce guide pin, the fluoroscopic image in side position according to C type arm X-ray machine again, adjust guide pin to neck of femur side position desired location, finally remove dynamic hip screw guider, carry out hip screw operation powered by conventional energy.This dynamic hip screw guider adopts the mode of locating after first otch, it needs larger otch to expose fully by neck of femur, just can make dynamic hip screw guider can be positioned over applicable position, not reach the object of minimally-invasive treatment in operation, the healing time of patient's wound is also longer.And substrate is while being close to lateral side of femur face, dynamic hip screw guider is difficult to fix, and keeps comparatively difficulty of needle angle, therefore can not locate quickly and accurately.
Summary of the invention
The advantages such as for the deficiency of above-mentioned prior art existence, the purpose of this utility model will provide a kind of external dynamic hip screw guider, can accurately locate fast entry point and keep needle angle, and wound is little, cost is low, radiationless.
To achieve these goals, the technical scheme that this utility model adopts is:
A kind of external dynamic hip screw guider, comprise guide pin sleeve pipe and guide pad, described guide pad is provided with base and guide edge, described base is provided with two parallel puncture needles, on described base, offer several guide pinholes parallel with described guide edge, described guide pin sleeve pipe is inserted in described guide pinhole.
Wherein, the angle of described base and described guide edge is 130 ° or 135 °.
Wherein, between two adjacent described guide pinholes, be equipped with the guide pin passage that the guide pin that can make to perform the operation passes through.
Further, described guide pinhole diameter is 4.1mm, and the center of circle spacing of two adjacent described guide pinholes is 5mm, and the external diameter of described guide pin sleeve pipe is that 4mm, internal diameter are 2.6mm, and the wide of described guide pin passage is 2.6mm.
Wherein, described in two, puncture needle lays respectively at the two ends on described base and vertical with described base.
Adopt after technique scheme, the advantage that compared to the prior art this utility model had is:
External dynamic hip screw guider described in the utility model, comprises base and guide edge, and its base is provided with two parallel puncture needles, can directly thrust skin, offers several guide pinholes parallel with guide edge on base.During use, in art, patient takes combined spinal-epidural anesthesia, and flat crouching on orthopaedics traction operation table carried out the reset of maneuver closed draw under C type arm X-ray machine perspective.With many pieces of Kirschner wires, be placed in before hip, after perspective, make the normotopia witness marker of guide pin, then will be placed in horizontal position at C type arm X-ray machine, Kirschner wire is placed in to lateral side of femur face, have an X-rayed lower mobile guide pin to neck of femur central projection, and mark.According to above-mentioned just, side position witness marker, the puncture needle of external localizer is directly arrived to the lateral surface of proximal femur and fixes through skin, optionally get a guide pinhole, guide pin and guide pin sleeve pipe are passed to guide pinhole, through lateral side of femur face after a little incision skin, the backward neck of femur direction of the top rake of controlling well pierces, with C type arm X-ray machine perspective guide pin position, generally have partially wrong, can be according to actual needs remaining guide pinhole in selective guide device on the upper side or on the lower side, and insert guide pin sleeve pipe and pierce location guide pin.Have an X-rayed again guide pin position, as normotopia position meets the requirements, remove remaining guide pin, the lower position of guide pin in neck of femur of adjusting of side position perspective.Until guide pin meets requirements of operation.While removing guider, first extract guide pin sleeve pipe out, then take out guider.According to existing location guide pin, the otch that operates is about 4～5cm, cuts skin and subcutaneous tissue, cuts fascia lata and vastus lateralis, appears the lateral surface to femur upper segment, carries out hip screw operation powered by conventional energy.This guider is simplified intertrochanteric fracture of the femur and the fracture of femoral neck fixing positioning action of threading a needle, can accurately locate fast entry point and keep needle angle, there is the advantages such as wound is little, cost is low, radiationless, can reduce and take the photograph sheet or have an X-rayed number of times, shortening operating time, alleviate patient's misery, guarantee that handling safety is reliable simultaneously, simple in structure, be easy to dismounting, be easy to carry, economical and practical, be applicable to finally apply.
