Description
Technical field
The utility model is the novel combination type external fixing rack fixed outside limbs fracture, belongs to outer fixed medical instrument skill
Art field is that the fixed external fixation device of limbs fracture is completed in cooperation.
Background technology
Mixed external fixator is gathered knowledge from around the world by Xia Hetao doctor etc., is digested, and application component exchanges and row
The mechanical engineering principle of row combination forms, and component has opposite independence and interchangeability, can form various configurations, combined type at random
External fixing rack is divided into three functions such as orthopedic, limb lengthening of fracture fixation, Bones and joints by function, by a large amount of Clinical practice
Afterwards, finding the component of part, there are many limitations, such as traditional combined type bar bar cramp head and shank collet can only be single
Folder needle or clamping bar, can make troubles, waste time in surgical procedure to doctor, on this basis, the design of my company
A kind of novel combination type external fixing rack, the same collet, can press from both sides needle also can clamping bar, facilitate doctor to operate, save the time.
Invention content
The utility model brings the time for conveniently saving outer fixed surgical procedure to the operation of mixed external fixator.
The technical solution of the utility model is as follows：
The utility model is novel combination type external fixing rack, and chuck component (2), horizontal collet are exchanged by connecting rod (1), shank
Component (3) collectively forms.Wherein, shank exchanges chuck component (2) by bar cramp (4), spring (5), bar cramp 2 (6), soket head cap screw
(7), cutting ferrule (8) forms, it is characterised in that：There are 1mm openings for the unilateral longitudinal direction of cutting ferrule (8), facilitate gripping by deformation, are inserted into bar cramp
Circular hole in, centre penetrates spicule or connecting rod, tightens soket head cap screw (7) and fixes spicule or connecting rod, can press from both sides in this way
Spicule can press from both sides connecting rod again, realize that shank exchanges, doctor is facilitated to operate；It is each on contact surface between bar cramp (4) and bar cramp 2 (6)
There are 60 teeth, it is non-slip during so that it is tightened using Principles of Gear Connection, ensure the fastness of spicule；Even with spring (5)
It connects, soket head cap screw (7) is fixed, and spring connection is advantageous in that：Bar cramp (4) in the axial direction can be 360 ° turns with bar cramp 2 (6)
It is dynamic, it ensure that the directionality of spicule, unclamp soket head cap screw (7) and realize that it struts pressurization function.Horizontal chuck component (3) is by horizontal folder
Body (9), upper cover (10), soket head cap screw (11) composition, it is characterised in that：Horizontal chuck component (3) exchanges collet group by shank
Part (2) is fixed in connecting rod (1), horizontal clamp (9) be rod shaped structure, penetrate in cutting ferrule (8), can it is axial 360 ° rotation, twist
Tight soket head cap screw (7) is fixed by horizontal chuck component (3), ensures spicule multi-dimensional nature inserting needle mode.
The utility model has the following advantages compared with prior art：
1 steps up spicule or connecting rod by cutting ferrule, realizes that shank exchanges, doctor is facilitated to operate；
2 two bar cramp contact surfaces utilize Principles of Gear Connection, ensure that its fastness, spring connection in the axial direction can
360 ° of rotations, ensure that the directionality of spicule, realize that it struts pressurization function by tightening soket head cap screw (7)；
3 horizontal clamps (9) be rod shaped structure, can it is axial 360 ° rotation, ensure that multi-dimensional nature inserting needle mode；
4 entire operations can be completed by a hexagon, easy to operate.
Description of the drawings
Fig. 1 is the general structure schematic diagram of the utility model.
Fig. 2 is that the utility model shank exchanges chuck component structural schematic diagram.
Fig. 3 is the horizontal chuck component structural schematic diagram of the utility model.
Fig. 4 is the utility model ferrule structure schematic diagram.
Specific implementation mode
The utility model operating instruction is as follows：
The several shanks of fixed operation basic need exchange chuck component (2), cross outside the novel combination type of completion complete set
Chuck component (3), several connecting rods, spicule and one are hexagon.Doctor selects the specification of spicule according to patients with fractures's situation
And cutting ferrule, if this time operation needs five spicules, it is necessary to a connecting rod, two horizontal chuck components (3) and three shanks
Exchange chuck component (2), it is first determined the spicule entry point for surrounding of fracturing squeezes into spicule, spicule is penetrated the utility model
In horizontal chuck component (3), then another spicule is squeezed into, according to spicule angle, adjusts horizontal chuck component (3) and shank exchanges collet
Component (2) arrives suitable angle, soket head cap screw (11) and soket head cap screw (7) is tightened with hexagon, according to same side
Method squeezes into two spicules for enabling one end, determines the 5th spicule position, and spicule, which is inserted in the shank with cutting ferrule, exchanges collet group
In part (2), spicule is squeezed into, is adjusted to suitable angle, soket head cap screw (7) is tightened with hexagon, completes outer fixed operation.
Claims (3)
1. a kind of novel combination type external fixing rack exchanges chuck component (2), horizontal chuck component (3) altogether by connecting rod (1), shank
With composition, wherein shank exchanges chuck component (2) by bar cramp (4), spring (5), bar cramp 2 (6), soket head cap screw (7), cutting ferrule
(8) it forms, it is characterised in that：The unilateral longitudinal direction of cutting ferrule (8) facilitates gripping by deformation there are 1mm openings, can splenial bone needle but also folder
Connecting rod realizes that shank exchanges.
2. novel combination type external fixing rack according to claim 1, it is characterised in that：Bar cramp (4) and bar cramp 2 (6) connect
