Abstract
The invention discloses a lobulated hollow forcing screw, comprising a lobulated screw cap and a hollow screw rod, wherein the lobulated screw cap is fixed at one end of the hollow screw rod, and the other end of the hollow screw rod is provided with external threads; the center of the lobulated screw cap is provided with a threaded hole extending to the hollow screw rod; and a plurality of arc-shaped fixed blocks are arranged on the periphery of the lobulated screw cap, and each fixed block is provided with a pair of interconnected lobulated hole. By virtue of the above mode, the lobulated hollow forcing screw disclosed by the invention can effectively achieve the integral fixation of compression and fixation of a fracture and the surrounding injured ligaments and joint capsules, so that the surgical operation is simpler, more convenient and easier, and the curative effect is more reliable.
Description
Technical field
The present invention relates to orthopaedics and enclose articular fracture field of surgical, particularly relate to a kind of leaflet cannulated compression screw.
Background technology
Hollow screw is that orthopaedics encloses the conventional internal fixation material of articular fracture operation, but existing hollow screw only has the effect of the fixing sclerite that pressurizes, for the avulsion fracture with periarticular ligament, joint capsule damage, without the effect that pressurization is fixed or fixedly secured.Traditional operation gives adding when sclerite screw is fixed with the reparation etc. of pad to fracture and periarticular ligament, joint capsule damage, also to apply band wire rivet or the fixing ligamentous joint capsule of other immobilization materials stitching in addition simultaneously, thus increase difficulty and operating time, and increase medical expense.
Summary of the invention
The technical problem that the present invention mainly solves be can not reach effectively for conventional hollow screw simultaneously, good fixing fracture, again can to the function of periarticular ligament, joint capsule pressurization fixed and repaired, a kind of leaflet cannulated compression screw is provided, can reach and enclose articular fracture and fix, firmly can repair periarticular ligament, joint capsule pressurization again, reduce operating difficulty.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of leaflet cannulated compression screw, comprising: leaflet nut and cored screw, described leaflet nut is fixed on cored screw one end, and the cored screw other end is provided with external screw thread; Described leaflet nut center has the screwed hole extending to cored screw; Be arranged with the fixed block of some circular arc outside described leaflet nut, each fixed block is provided with the leaflet hole be interconnected for a pair.
Preferably, described fixed block has four, and four fixed blocks are evenly distributed on leaflet nut periphery.
Preferably, described leaflet nut and external screw thread spaced apart.
The invention has the beneficial effects as follows: the present invention effectively can reach fracture with compressive and fix the ligament, the joint capsule that damage with surrounding and be fixed on one, and make operation technique more easily easy, curative effect is more reliable.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of a kind of leaflet of the present invention cannulated compression screw one preferred embodiment;
Fig. 2 is the plan structure schematic diagram of shown a kind of leaflet cannulated compression screw.
In accompanying drawing, the labelling of each parts is as follows: 1, cored screw; 2, leaflet nut; 3, screwed hole; 4, fixed block; 5, leaflet hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:
A kind of leaflet cannulated compression screw, comprising: leaflet nut 2 and cored screw 1, described leaflet nut 2 is fixed on cored screw 1 one end, and cored screw 1 other end is provided with external screw thread, and leaflet nut 2 is spaced apart with external screw thread; Described leaflet nut 2 center has the screwed hole 3 extending to cored screw; Fixed block 4, four fixed blocks 4 that described leaflet nut 2 periphery is fixed with four circular arcs are evenly distributed on leaflet nut 2 periphery, and each fixed block 4 is provided with the leaflet hole 5 be interconnected for a pair.Can penetrate in the leaflet hole 5 of leaflet nut 2 and repair the fixing material sewing up ligament, joint capsule, can fracture surrounding ligaments, the joint capsule reparation pressurization of circular arc fixed block simultaneously on leaflet nut is fixed, and makes fracture fixation and periarticular capsule, ligament repair more firm.
The invention provides a kind of simple, practical leaflet cannulated compression screw, effectively can reach fracture with compressive and fix the ligament, the joint capsule that damage with surrounding and be fixed on one, make operation technique more easily easy, curative effect is more reliable.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the present invention and accompanying drawing content to do, or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
Claims (3)
1. a leaflet cannulated compression screw, is characterized in that, comprising: leaflet nut and cored screw, and described leaflet nut is fixed on cored screw one end, and the cored screw other end is provided with external screw thread; Described leaflet nut center has the screwed hole extending to cored screw; Be arranged with the fixed block of some circular arc outside described leaflet nut, each fixed block is provided with the leaflet hole be interconnected for a pair.
2. a kind of leaflet cannulated compression screw according to claim 1, is characterized in that: described fixed block has four, and four fixed blocks are evenly distributed on leaflet nut periphery.
