Technical problem to be solved in the utility model is to provide the anatomical form chest rib claw bone-knitting device that a kind of curative effect is good, healing efficiency is high.
For solving the problems of the technologies described above adopted technical scheme: a kind of anatomical form chest rib claw bone-knitting device, comprise blade plate main body and the multipair claw hook being symmetrically set in the blade plate main body left and right sides, described blade plate main body is strip, and the bottom surface of described blade plate main body is the space arc-shaped curved surface matched with human body rib lateral surface anatomic form.
Further, described blade plate main body is made up of the continuous splicing of more piece blade plate head and the tail.
Further, bending is c-shaped all in opposite directions for often pair of described claw hook, and each in described claw hook, wherein the C shape A/F of side claw hook is all less than the C shape A/F of opposite side claw hook.
Further, wherein the C shape A/F of claw hook described in side is 3.5 ~ 8mm, and the C shape A/F of claw hook described in opposite side is 4.5 ~ 8.5mm.
Further, the two ends of described blade plate main body relative turn-back predetermined angular respectively.
Further, the windup-degree of described blade plate main body one end is 7 ~ 12 °, and the windup-degree of the described blade plate main body other end is 22 ~ 28 °.
Further, the claw hook lateral surface that described blade plate main body two ends are positioned at the left and right sides is respectively equipped with secondary side hook.
Further, be stitched together by mortise-tenon joint between the described blade plate of each joint.
Beneficial effect: this anatomical form chest rib claw bone-knitting device designs by adopting human body rib anatomical data, namely the floor design of blade plate main body is the space arc-shaped curved surface matched with human body rib lateral surface anatomic form, blade plate body floor and human body rib side are agreed with completely, meet human body rib anatomical physiology characteristic, good fixing effect, at utmost reach the anatomical reduction of fracture site, reduce the complication such as patient's postoperative pain.

Detailed description of the invention
Referring to figs. 1 through Fig. 6, a kind of anatomical form chest rib of this utility model claw bone-knitting device, comprise blade plate main body 10 and the multipair claw hook 20 being symmetrically set in blade plate main body 10 left and right sides, blade plate main body 10 is in strip, and the bottom surface of blade plate main body 10 is the space arc-shaped curved surface matched with human body rib lateral surface anatomic form.
In the present embodiment, blade plate main body 10 is formed by three joint blade plates, be respectively front side blade plate 11, middle side joint hone lamella 12, rear side blade plate 13, overall blade plate main body 10 is connected to form by space between three joint blade plates, also the placement of mortise-tenon joint can also be adopted between each joint blade plate together combined and spliced, Fig. 4 and Fig. 5 illustrates the mode of two kinds of mortise-tenon joint, certainly also can adopt the mortise-tenon joint of other versions, needs dismounting to be separated each joint blade plate flexibly according to actual operation.
The floor design of blade plate main body 10 is the space arc-shaped curved surface matched with human body rib lateral surface anatomic form, when blade plate main body 10 is fixed on rib, its bottom surface and human body rib side are agreed with completely, meet human body rib anatomical physiology characteristic, good fixed effect can be reached, at utmost reach the anatomical reduction of fracture site, reduce the complication such as patient's postoperative pain.
This anatomical form chest rib claw bone-knitting device abandoning tradition blade plate only considers the form of the conventional anatomic parameter such as length, width, according to the anatomical features of every root bone, not only consider the conventional anatomic parameter such as length, width, more take into full account and make this bone-knitting device meet rib anatomical physiology characteristic by the important parameter that frame bending angle, distortion angle etc. be can not ignore.
Wherein, this bone-knitting device not only considers the anatomical features of each root bone, also take into full account that the front rib of each root bone, side rib, aft rib also have respective profile feature, front side blade plate 11 is designed to arc according to the anatomical features of front rib, its crooked radian is 62 ~ 67 °, to meet the physiologic radian of this section of rib.Middle side joint hone lamella 12 is designed to arc according to the anatomical features of side rib, and its crooked radian is 72 ~ 79 °, to meet the physiologic radian of this section of rib.Rear side blade plate 13 is designed to arc according to the anatomical features of aft rib, and its crooked radian is 129 ~ 135 °, to meet the physiologic radian of this section of rib.
As preferably, bending is c-shaped all in opposite directions for often pair of claw hook 20, in each pair of claw hook 20, wherein the C shape A/F of side claw hook 20 is all less than the C shape A/F of opposite side claw hook 20, see Fig. 4, because the variable thickness of the both sides of the edge of human body rib causes, the anatomical features of this rib is not considered in tradition claw type blade plate, to mate anastomose property low with rib clamping, often easily cause intercostal vessels and nerve injury, both sides claw hook 20 adopts different width according to the different thickness in rib both sides of the edge, make claw hook 20 fully clamping can hold rib tightly, make each joint blade plate can better and rib fit, reach the effect of well fixing rib.Wherein the C shape A/F of side claw hook 20 is preferably 3.5 ~ 8mm, and the C shape A/F of opposite side claw hook 20 is preferably 4.5 ~ 8.5mm.
Wherein, the two ends relative turn-back predetermined angular respectively of blade plate main body 10, the blade plate saved to make front and back two can better fit with rib, according to the anatomical features of rib, namely before and after every root bone, two all has and to a certain degree reverses, and blade plate main body 10 one end plate body centrage that connects reverses certain angle, is preferably 7 ~ 12 °, blade plate main body 10 other end connects plate body centrage turn-back certain angle, is preferably 22 ~ 28 °.
As preferably, claw hook 20 lateral surface that blade plate main body 10 two ends are positioned at the left and right sides is respectively equipped with secondary side hook 21, the bending direction of secondary side hook 21 is consistent with the bending direction of claw hook 20, be arranged on the force part of the secondary side hook 21 on claw hook 20 lateral surface as dismounting, the dismounting of bone-knitting device is carried out after being convenient to Rehabilitation, convenient to operation.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but this utility model is not limited to above-mentioned embodiment, in the ken that described technical field those of ordinary skill possesses, various change can also be made under the prerequisite not departing from this utility model aim.
