Description
Technical field
this utility model relates to orthopedic medical device technical field, particularly with a kind of chest rib bone-knitting device.
Background technology
The slight fracture of rib of majority is cured by expectant treatment, but for complicated and severe fracture of rib, as many many places fractures of rib the flail chest that causes, the serious breathing caused by paradoxical breathing and circulatory function obstacle entail dangers to life, often need positive treatment.For chest rib fracture, chest rib fracture fixation device conventional at present has:
(1) blade plate, mainly by two side perforatings at the fracture line of rib, with screw by Interal fixation on the rib broken, or with steel wire steel plate to be bundled on the rib that breaks and to be fixed, because its bending resistance is large, postoperative patient chest pain is serious, often needs second operation to take out, and this type of steel plate often has screw loosening in addition, the phenomenon generation such as come off.
(2) claw type blade plate, mainly captures fixing rib by fixed claw, and fixing means is simple, but biomechanical strength is not high, likely forms the instability healing of fracture, has the risk of infection, pain and second fracture; And the type claw type blade plate does not press the anatomical physiology design of rib, and mate anastomose property low with rib, so that fixing poor with molding effect, easily cause intercostal vessels and nerve injury.
(3) Medullary fixation apparatus, is embedded on the cortical bone internal layer around pulp cavity, to reach good internal fixtion mainly through intramedullary needle.But, due to the rotation displacement of the rib broken ends of fractured bone and the displacement of needle body self, easily there is malunion of fracture or bone does not connect.Medullary fixation apparatus often needs also just can reach more satisfactory fixed effect with other fixture coupling, uses inconvenience.
In view of this, the defect of above-mentioned prior art need be improved, provide a kind of and cure fixed effect chest rib fracture fixation device good, easy to use.
Utility model content
Technical problem to be solved in the utility model is to provide the anatomical form chest rib screw lock fixed pattern bone-knitting device that a kind of curative effect is good, healing efficiency is high and easy to use.
For solving the problems of the technologies described above adopted technical scheme: a kind of anatomical form chest rib screw lock fixed pattern bone-knitting device, comprise blade plate main body and multiple lock screw, described blade plate main body is long strip-board shape, 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, and in described blade plate main body, interval has multiple lock hole embedding locking for lock screw along its length.
Further, the top of each described lock hole is hemispherical, and the bottom of each described lock hole is cylindricality, and the head of described lock screw is the half sphere shape that can be embedded in lock hole top.
Further, the apical head of described lock screw is lower than the end face of blade plate main body.
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 °
Beneficial effect: this anatomical form chest rib screw lock fixed pattern 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; Lock screw is embedded design simultaneously, and lock screw top is not protruded in blade plate body surfaces, reduces human body to the foreign body sensation of implant, also improves the steadiness of lock screw, avoid coming off.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is described further;
Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is the middle partial cutaway schematic of this utility model embodiment.
Detailed description of the invention
See figures.1.and.2, a kind of anatomical form chest rib of this utility model screw lock fixed pattern bone-knitting device, comprise blade plate main body 10 and multiple lock screw 20, blade plate main body 10 is in long strip-board shape, 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, and in blade plate main body 10, interval has multiple lock hole 11 embedding locking for lock screw 10 along its length.
In the present embodiment, blade plate main body 10 is fitted fracture of rib place, through corresponding lock hole 11, blade plate main body 10 and rib are being locked firmly by several lock screw 20, floor design due to 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 laminating 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 screw lock fixed pattern 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, blade plate main body 10 is made up of leading portion, stage casing, back segment three sections, leading portion 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.Stage casing 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.Back segment 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, the top of each lock hole 11 is hemispherical, the bottom of each lock hole 11 is cylindricality, the head of lock screw 20 is the half sphere shape that can be embedded in lock hole 11 top, the apical head of lock screw 20 is lower than the top end surface of blade plate main body 10, the head design of lock screw 20 is half sphere shape of coincideing corresponding to lock hole 11 top, lock screw 20 can be made better to embed locking, avoid the top of lock screw 20 to protrude the surface of blade plate main body 10 simultaneously, reduce human body to the foreign body sensation of implant.
The two ends relative turn-back predetermined angular respectively of blade plate main body 10, can better fit with rib to make the blade plate at two, front and back, according to the anatomical features of rib, namely before and after every root bone, two all has and to a certain degree reverses, blade plate main body 10 one end connect plate body centrage reverse certain angle, be preferably 7 ~ 12 °, blade plate main body 10 other end connects plate body centrage turn-back certain angle, is preferably 22 ~ 28 °.
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.
