Description
Technical field
This utility model relates to technical field of medical instruments, is a kind of belt-type adsorbable bone folding fixing band.
Background technology
Clinically, it is fixing that the fracture fixation band is usually used in fracture site binding, and fixing band commonly used is at present made by metal material usually, as the tension band made by steel wire or wirerope etc.No matter metal material is in rigidity, intensity, still the fatigue resistance aspect is all more satisfactory, but implant deteriorating of causing, metal anaphylaxis because of long-term, stress is blocked the fracture once more that the osteoporosis that acts on and cause might cause postoperative again, need carry out second operation taking-up steel nail or clamping plate after adding union of fracture, it is painful for the second time that this just means that also the patient not only will bear, also increased simultaneously financial burden, moreover, metal material can influence patient's postoperative and carry out inspections such as CT or MRI, thereby might influence the operation quality.
Ideal orthopaedics material should be safety, use reliably, easily and can degrade and need not take out.Adopt Biodegradable material, behind the implant into body of making as materials such as poly-Acetic acid, hydroxy-, bimol. cyclic ester, polylactide, polylactic acid such as nail, its inherent initial strength can play the effect of the positive bone material of conventional steel.As time goes on, fracture is healing gradually, and biodegradable nail is absorbed by tissue gradually simultaneously, does not accumulate in vivo, does not almost have toxic action; Its original space can be substituted by osseous tissue, and patient also need not be subjected to the misery of performing the operation once more.Because the approximate spongy bone elastic modelling quantity of the elastic modelling quantity of absorbable material allows the small activity of the local generation of fracture end, be beneficial to union of fracture in addition; The product aseptic packaging of making must not sterilized, and is easy to use; Its nonmetallic characteristic does not influence patient's postoperative and carries out inspections such as CT or MRI any time.Therefore, say that in theory absorbable material is optimal orthopaedics material.At present, the medical nail of biodegradation both domestic and external has entered clinical practice, but all is in the elementary development phase, and does not see so far with Biodegradable material and make the report that can absorb fixing band, does not more see the report that belt-type fracture fixation band is arranged.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, easy to use, can be by the belt-type fracture fixation band of human body degraded and absorbed.
This utility model adopts Biodegradable material to make, and is made up of snap close, bundling belt and compression screw.Snap close is equivalent to the metal snap close of belt, and bundling belt is equivalent to belt.Its metal latch of usually said belt is buckled and is provided with a button shape projection, and belt is provided with lockhole a plurality of and button shape projection coupling, during use the belt tail end is inserted snap close, and the lockhole that after tightening up button shape projection is inserted belt gets final product.Yet, as bundling belt, if offer lockhole above, and be a plurality of lockholes, be certain to have a strong impact on the tension force tolerances of bundling belt, be easy to fracture, moreover, all keep at a certain distance away between a plurality of lockholes, can't regulate the suitable elasticity of bundling belt, therefore snap close of the present utility model and bundling belt are different from above-mentioned belt.Snap close of the present utility model is hollow cuboid, the front/rear end opening, the end face length of top can be isometric with the bottom surface, also can be shorter than the bottom surface, end face is provided with a screw, this screw is provided with female thread, and itself and the external screw thread coupling that is threaded onto the compression screw in this screw laterally are provided with many row's pawls on the bottom surface of snap close inner chamber.One end of this utility model bundling belt and the bottom surface of snap close rear end are connected in one, the junction is certain arc angle, so that along fracture site bending binding, the one side that bundling belt is affixed on surface of bone laterally is provided with pawl, pawl on this pawl and snap close inner chamber bottom surface coupling is complementary, tightens up the back by the mutual interlock between the pawl on pawl on the bundling belt and the snap close inner chamber bottom surface and tighten compression screw and fixed so that the bundling belt tail end is inserted snap close.
During use, outside fracture segment that after fracture site resets bundling belt of the present utility model is surrounded on routinely or the broken bone piece, tail end penetrates snap close, adjust the position and tighten up bundling belt, make the pawl of bundling belt and the pawl interlock on the snap close inner bottom surface, tighten compression screw, cut off the redundance of bundling belt tail end, can operate routinely.
Advantage of the present utility model is: 1) because the fracture fixation band is belt-type, make operation become efficient and convenient; 2) because the adjacent distance of respectively arranging between the pawl that is used for fixing is very near, the elasticity that is easy to regulate binding; 3) multiple tooth interlock adds that the pressurization of compression screw makes bundling belt fix quite firmly; 4) be affixed on the slip that bundling belt pawl on the surface of bone can prevent fixing band; 5) pliability of absorbable material is good than metal material, resists to fracture and bending easily the surface of bone of fitting better; 6) since absorbable material place and do not influence patient's postoperative in the body and carry out inspections such as CT or MRI any time, be convenient in time pinpoint the problems, improve the operation quality, and also needn't operate on taking-up later on, not only convenient, and alleviated patient's misery and the medical expense of being born.
