The specific embodiment
With the following drawings and preferred embodiments of the present invention, further set forth the technological means that the present invention takes for reaching predetermined goal of the invention.
As shown in Figures 1 and 2, it is the multiple preferred embodiment that discloses the spiral fracture fixing apparatus of the present invention, described spiral fracture fixing apparatus is to comprise a spiral fixing band 1, this spiral fixing band 1 is the elongate body that a flexible material forms screw winding shape, can helical coated be fixed on bone 3 outsides of fracture as Fig. 3 makes this spiral fixing band 1, the length of described spiral fixing band 1 and the number of turns of spiral determine according to factors such as applied bone 3 length.
As shown in Figure 1, described spiral fixing band 1 is the helical form for two adjacent sections lateral margins in each pitch with spacing.Again as shown in Figure 2, described spiral fixing band 1 also can be the helical form of two adjacent sections lateral margins contacts in each pitch, or described spiral fixing band 1 also can be the feasible examples such as the overlapping helical form of two adjacent sections sides in each pitch.
The material of described spiral fixing band 1 is biological degradable material, for example: and polylactic acid (Polylactide, PLA), or bio-compatible material, for example: pure titanium (Ti) or titanium alloy or vitallium etc.
In addition, as shown in Figure 4, described spiral fracture fixing apparatus also can arrange in spiral fixing band 1 one end a fairlead 11, this fairlead 11 is that central shaft along spiral fixing band 1 is to protruding out outwardly, described spiral fixing band 1 also can be set up a fixed part 12 with respect to the other end of fairlead 11, utilize described fixed part 12 to provide a retaining element 2 to be fixed on bone, described retaining element 2 can be the equivalent element of staple or bone screw or other.
When the spiral fracture fixing apparatus of the present invention is applied to fracture fixing operation, the bone of fracture 3 is reset to normal position by doctor, again according to the form of fracturing, select the spiral fracture fixing apparatus of suitable length, and outside bone 3 one end of corresponding fracture the suitably otch of size of lateral incision, with manual or mechanically actuated mode, otch is passed in spiral fixing band 1 one end, as shown in Figure 5, and pull open spiral fixing band 1 front end and be placed on bone 3 outsides, secondly, rotation spiral fixing band 1 is not placed on the part in bone 3 outsides, helical coated is lived the bone 3 of fracture along bone 3 directions and by the gap between bone 3 and tissue to make spiral fixing band 1, spiral fixing band 1 curls up completely after bone 3, as shown in Figure 3, intactly helical coated is lived bone 3, and reach the object of fracture fixation by the intensity of spiral fixing band 1 self.
In aforementioned fracture fixing operation, as shown in Figure 4, when described spiral fixing band 1 front end has fairlead 11, that the front end that has fairlead 11 with this spiral fixing band 1 penetrates in otch, be placed on bone 3, rotate again spiral fixing band 1, wherein can utilize laminar fairlead 11 be easy to by bone 3 and tissue between gap and along bone 3 directions and helical coated live fracture bone 3, in order to the carrying out of operation, in addition, this spiral fixing band 1 also can utilize the fixed part 12 of rear end, provide doctor with steel nail, the retaining elements such as bone screw 2 stretch into by otch, be fixed in bone 3 and run through fixed part 12, spiral fixing band 1 is more firmly fixed on bone 3.
From illustrating above, the spiral fracture fixing apparatus of the present invention utilizes spiral fixing band to envelope in a spiral manner the bone of fracture completely, and reach the object of good fixing fracture site by the intensity of spiral fixing band self, at operative connection, the use of the spiral fracture fixing apparatus of the present invention, only must cut a little otch and can carry out the operation of spiral fixing band helical coated bone, only easy to be easy in operation, can shorten operating time.For sufferer, also, because postoperative wound is little, contribute to postoperative recovery.
