Abstract

The utility model discloses a multifunctional dynamic hip screw guider comprising a substrate and a guide block, wherein the substrate and the guide block are integrated; at least two parallel guide needle passages are arranged within the guide block; the guide block is a locking-groove drawable structure; an included angle between the substrate and the guide block is 130-135 degrees; specifically, the included angle between the substrate and the guide block is 130 degrees; or the included angle between the substrate and the guide block is 135 degrees. The multifunctional dynamic hip screw guider is practicable, low in production cost, capable of quickly and accurately positioning a needle inserting point and keeping a needle inserting angle, less in injury and free of radiation.

Description

A kind of multifunction dynamic hip screw guider

Technical field

This utility model relates to a kind of hip screw guider of using when treating femur intertrochanteric fracture, particularly a kind of multifunction dynamic hip screw guider.

Background technology

When clinical internal fixation treatment neck of femur and intertrochanteric fracture of the femur, all need insert the guide pin location earlier.Normally carry out guide pin and insert, all need adopt C arm machine to have an X-rayed behind each inserting needle whether to get into to put in place, but commonly usedly grasp badly, and need repeatedly blindness to operate because of last or the following skew of its entry point, top rake and collodiaphyseal angle with the inspection guide pin with doctor's clinical experience.

At present, human society gets into aging, and neck of femur and intertrochanteric fracture of the femur are old people's common frdquently encountered diseases.It is operation method commonly used at present that intertrochanteric fracture of the femur is used the DHS internal fixation, and one of key operation of operation is to insert the location guide pin, and it has determined position and the direction of screw in neck of femur, and the success or failure of performing the operation are played an important role.But because the neck of femur anatomical structure is special, on Different Plane, have collodiaphyseal angle and top rake, and the position deeply, hidden, make correctly inserting of guide pin of location have certain difficulty.How will locate guide pin and correctly insert, in recent years, many scholars have designed some operating theater instruments, even have used computer assisted navigation system.In the similar apparatus of design principle, the localizer of design such as Wu Lin, the fixed point puncture needle need puncture to the femoral head central point; And how the fracture of femoral neck patient reduction of the fracture need maintain lower limb inward turning position; At this moment, this point is difficult for being punctured to by the acetabular bone embedding; And this is nearer from abdominal cavity and thigh portion nervus vasculairs, is prone to stab these vital tissues.Yu is superfine to be used for the hollow nail internal fixation with computer navigation, have precision, the error that can avoid the mechanical guiding device that improves operation, the advantage that shortens operating time, but this system price is expensive, is difficult to popularize at basic hospital at present.Use conventional DSH angle guideline,, pierce once more after the adjustment only if the operator at X line perspective straightforward manipulation down, pierces behind the guide pin as finds on the upper side or on the lower side, need to take out guide pin in the art, as dissatisfied, need repetitive operation once more.Cause repeatedly inserting needle repeatedly, bring iatrogenic infringement to the patient, repetitious C arm machine perspective is brought radiation injury to patient and medical personnel.

The utility model content

This utility model technical problem to be solved is the deficiency to prior art, and a kind of novel multifunctional dynamic hip screw guider is provided.

To achieve these goals, the measure taked of this utility model:

A kind of multifunction dynamic hip screw guider comprises substrate and guide pad, is an integral body between substrate and the guide pad, is provided with at least two guiding needle tracks that are parallel to each other in the said guide pad; Guide pad is a draw-in groove drawing and pulling type structure;

The angle of described substrate and guide pad is 130 °～135 °;

The angle of described substrate and guide pad is 130 °;

The angle of described substrate and guide pad is 135 °.

The beneficial effect of this utility model: practicality, production cost is low, can accurately locate entry point fast and keep needle angle, and wound is little, radiationless.

The specific embodiment

A kind of multifunction dynamic hip screw guider comprises substrate 9 and guide pad 8, is an integral body between substrate 9 and the guide pad 8, is provided with at least two guiding needle tracks 7 that are parallel to each other within the described guide pad 8; Guide pad is a draw-in groove drawing and pulling type structure, and described substrate 9 is 130 °～135 ° with the angle of guide pad 8; Described substrate 9 is 130 ° with the angle of guide pad 8; Described substrate 9 is 135 ° with the angle of guide pad 8.

When using this utility model, at first, the patient takes epidural anesthesia or general anesthesia, flat crouching on orthopedic traction bed, under C type arm X line machine perspective with traction frame reduction by traction fracture end; Under femoral greater trochanter, make long incision 4～6cm, cut skin, reach subcutaneous tissue, cut fascia lata and vastus lateralis, appear lateral surface to femur upper segment; Again the substrate 9 of this utility model is close to the lateral side of femur face, controls well after the top rake, an optional guiding needle track 7 pierces guide pin to the neck of femur direction; With C type arm X line machine perspective guide pin position, inclined to one side mistake is generally all arranged, can select according to actual needs that remaining guiding needle track 7 carries out guide pin in this utility model; Reuse C arm machine perspective guide pin position in the requirement position, is promptly removed remaining guide pin like normotopia; The position of adjustment guide pin in neck of femur side position under C arm machine perspective is positioned at the neck of femur desired location until guide pin again, removes this multifunction dynamic hip screw guider then; Carry out hip screw operation powered by conventional energy, thereby realize the purpose of this utility model.

Those skilled in the art's simple change and replacement in this area all are within the protection domain of this utility model.
