Abstract
The utility model discloses an external supporting bracket to prevent sliding direction-variation of double-threaded compression needle or nail for intertrochanteric or neck fracture of femur, which comprises a double-threaded compression needle, a single-threaded fixing needle, a middle sliding and direction-variation needle groove of the compression body and an external supporting bracket, wherein when connected, the two external supporting brackets form twin columns; the double-threaded compression needle is provided with a conical needle tip, a coarse thread section, a non-thread section, a fine thread section, and tail of the needle bar is semicircular; the single-threaded fixing needle is provided with a needle tip, and tail of the threaded needle bar is semicircular; the external supporting bracket is provided inside with dovetail grooves and a groove-shaped sliding block, and the compression screw hole bracket is respectively provided with a screw hole and a screw rod; the groove-shaped sliding block can adjust distance and direction with invariant moments and multidirectional restrictions, making assembling works more convenient and enabling intersection of a plurality of needles and nails. The needles and nails can be fixed and improper needle and nail positions can be detected in a short time for momentarily adjustment of the position and direction of the needles and nails to reduce damages to bone substances, muscles and blood circulation. With help of the utility model, no operation is needed, and no pain is caused; besides, the facture gap can be shrunk to speed fracture healing process.
Description
Technical field
This utility model relates to a kind of neck of femur and intertrochanteric fracture double cut Needle with pressure-increasing means, follows closely slippage break-in fixed mount, belongs to the medical apparatus and instruments of treatment fracture.
Background technology
At present, neck of femur and intertrochanteric fracture are old people's frequently-occurring diseases, adopt traction and external plaster fixation, make the essential long-term bed of patient, and be painful big, nurses very inconveniently, and complication is many; Operative treatment adopts gooseneck nail internal fixation more, needs long incision, peels off cut-out muscle on bone, and wound is big, and is hemorrhage many, the risk height, and the gooseneck that needs second operation to take out on the folding bone is followed closely; Common exterior fixation bracket and percutaneous drift bolt bone cement expopexy, this type of technology adopts steinman pin more, but should be poor at the fracture end restraining forces, effective stable fracture position, because the pin position disperses, far away apart from fracture end, significantly restriction muscular movement reduces patient's autonomic activities amount, and joint motion spoke degree is little, can cause ankylosis, and backshank is outside support, activity dressing inconvenience, and external fixer is fixed pin, pitch of nails, can not adjust pin, the nail direction can not be along with rotation, each pin of assembling difficulty, nail enter and make single nail fixedly make fixing folding end instability.
Summary of the invention
In order to overcome above-mentioned deficiency, this utility model provides a kind of neck of femur and intertrochanteric fracture double cut Needle with pressure-increasing means, follows closely slippage break-in external fixer, and is simple in structure, easy to use, do not need operation, it is little to have wound, the folding end is stable, and fixation is not subjected to pin, nail position and direction restriction, simple and convenient assembly, no pain, not hemorrhage, to the muscle not damaged, but early functional exercise promotes union of fracture, effectively reduce complication, and do not influence dressing.
The technical scheme that its technical problem that solves this utility model adopts is: it is made up of two screw thread Needle with pressure-increasing means, nail, single thread locking pin, support body external fixer, external fixer goes to upper and lower double columnar form after connecting, the top of two screw thread Needle with pressure-increasing means is provided with the taper needle point, front end is provided with coarse-pitch thread, the stage casing is that circular shank does not have screw thread, back segment is provided with fine thread, the shank tail end is the semicircular body needle body, so as during inserting needle on clip and the external fixer corresponding cooperation press fixing; The single thread locking pin is provided with needle point on the top of pin, uses during for inserting needle, is provided with single thread at the rear portion of needle point, and tail end is the semicircular body shank, presses fixingly for cooperating in the semicircle chute on clip inserting needle and the external fixer, makes two screw needles, nail stable; Cylindrical external fixer is divided into fan, two semicylinder external fixers of lower fan, the half slot of a plurality of slip angles is housed in the dovetail groove on the semicylinder external fixer, on two semicylinder external fixers, be provided with a plurality of corresponding vertical threaded bore, press its shank afterbody fixing with pressing fixed screw, after making two semicircular body external fixers involutory, the formation cylindrical body connects back formation and upward saves, saves down twin columns type external fixer.
The beneficial effects of the utility model are: scientific and reasonable for structure, easy to usely need not operate on operation, only need local anaesthesia, wound is little, basic no pain, because it is thick, the effect of fine thread, fracture gap is dwindled, each pin, nail can change direction with chute makes pin, nail intersects fixing, and internal fixation is firm, plus-pressure is strong, the folding end is stable, and external fixation is firmly safe and reliable, and the removable direction that can arbitrarily change of slipping block is not limited by pitch of nails and direction, postoperative is found can adjust nail position and direction at any time when the nail position is bad, external fixer does not have backshank outward, and normally functional exercise is carried out in dressing, anterior pointed circular cone hole-opening voluntarily when entering owing to the pressurization needle point, reduced sclerotin, the infringement of muscle and blood fortune, accelerating union of bone fracture.
