Detailed description of the invention
The locking external fixer for clavicular fracture treatment that the utility model proposes, it is characterized in that, this locking external fixer is made up of class S-shaped cylinder support body or rectangle support body and multiple fracture fixation screw, this S-shaped cylinder laterally has multiple screwed hole, the screwed hole of this support body matches with the screw thread of screw, this fracture fixing screw links into an integrated entity with support body in being threaded into hole, and fracture fixation screw head is fixed with fracture clavicle.
Described S-shaped cylinder support body or rectangular support body are formed by connecting by tilting section, straightway and V-arrangement curved segment, and profile and the size of this support body match with clavicle；Wherein the tilting section of this support body and the both sides cross direction profiles of V-arrangement curved segment have multiple screw holes of same apertures；The length of straigh line of this support body is 65-75mm, a diameter of 3.0mm-4.0mm of this fracture fixing screw.
The degree of depth sum of the distance between described fracture fixation screw length and the thickness of support body, support body and skin and the soft tissue thickness outside bone and embedding clavicle matches.
Locking external fixer for clavicular fracture treatment of the present utility model, the advantage of traditional clavicular plate and external fixer is combined, S-shaped is cylindrical or rectangle support body designs according to the appearance profile of clavicle, setscrew is combined into one with support body screwed hole, setscrew tip 5 is screwed into human body clavicle, with fixing fracture.There is Wicresoft, without features such as second operation taking-ups, it is possible to effectively reduce the multiple complications of clavicular fracture treatment.
This device is external owing to support body is positioned at, and support body, in the case of meeting the intensity needs of length, can be metal or any materials such as carbon steel, carbon fiber such as rustless steel, aluminium alloy, titanium alloy.
The width of support body and thickness are all to meet in the case of the size of screwed hole depending on according to the strength of materials selected.
In conjunction with the embodiments and accompanying drawing is further described below a kind of miniature locking external fixer for clavicular fracture treatment that the utility model proposes:
The locking external fixer of the present embodiment is made up of class S-shaped cylinder support body or rectangle support body and multiple fracture fixation screw.
The support body of the present embodiment is as shown in Figure 1, this support body 1 is formed by connecting by tilting section, straightway and V-arrangement curved segment, wherein tilting section and straightway be 147 ° of angles, straightway and V-arrangement curved segment be connected in 147 ° of angles, the another side of straightway and V-arrangement curved segment is 90 ° of angles；And the end of V-arrangement curved segment is same with straightway high；The length of each section is respectively as follows: tilting section 40mm, straightway 70mm, and V-arrangement curved segment both sides are respectively 30mm, 17mm.Wherein the both sides of tilting section and V-arrangement curved segment are uniformly distributed the screw hole 2 respectively 7,5 and 2 of same apertures, a diameter of 3.5mm；The screwed hole of this support body matches with the screw thread of fracture fixation screw.The quantity of screwed hole also can according to the intensity of material and application time be screwed into screw position motility depending on.It is easy to the fixed position of doctor's unrestricted choice screw as required, simultaneously in order to alleviate elongated support body weight.The degree of depth sum of the distance between fracture fixation screw length and the thickness of support body, support body and skin and the soft tissue thickness outside bone and embedding clavicle matches.
Screwed hole 2 on the support body of the present embodiment is up big and down small stepped, become with elongated support body 1 90 degree vertical, upper end is the screwed hole that the screw thread with screw matches, and lower end is the through hole that diameter is slightly less than threaded upper ends hole.
The structure of the fracture fixation screw of the present embodiment is as in figure 2 it is shown, be made up of integral part of most advanced and sophisticated 5, cylindrical midsection 4 and afterbody 3, and wherein, most advanced and sophisticated 5 is with externally threaded cone, in order to hold skeleton；The external diameter in stage casing 4 matches with the aperture, lower end of the screwed hole 2 of elongated support body, and the external diameter in stage casing 4 is slightly less than aperture, screwed hole 2 lower end, and its stage casing is through the lower end of screwed hole 2, and tip contacts and enter human body lock bone with fixing fracture through smooth with skin and soft tissue；Afterbody 3 is provided with external screw thread, diameter matches with the internal diameter of screwed hole 2 upper end, afterbody top middle portion has screw, it is simple to be screwed in the screwed hole 1 of elongated support body 1 by screw with corresponding tool, and makes the tip 5 of screw be screwed into the human body clavicle fracture with fixing relevant position.The threaded upper ends of afterbody 3 and screwed hole 2 is fixed.The screw of the present embodiment uses medical stainless steel or titanium alloy material to make.
Locking external fixer for clavicular fracture treatment of the present utility model, its operative process is as follows:
First passing through incision or Guan Bi prying and pulling mode resets clavicular fracture, with the most fixing fracture such as Kirschner wire, hollow nail or spring nail, perspective is lower confirms that the position of locking external fixer is correct, with Kirschner Wire Drilling, then is screwed into the fixing fracture of screw.
Reliable for fixing intensity, it is proposed that screw is uniformly distributed, and interval screwed hole is screwed into screw, and effect is more preferable.
For comminuted fracture, stretching traction and recover clavicle length, pulverize little sclerite, reach functional reduction after taking, then place locking external fixer, now screw is tried one's best beat more, in order to increase fixed effect.
The profile of clavicle locking external fixer breast piece is designed according to the appearance profile of clavicle surface skin, and configuration design becomes big " S-shaped ", in order to meet the mechanics of fixing clavicle and needs attractive in appearance to greatest extent.Material for the locking external fixer of clavicular fracture treatment of the present utility model is positioned at external owing to not contacting skin, can be the lightweight materials such as rustless steel, titanium alloy, carbon fiber or aluminium alloy.Being evenly distributed with screwed hole on support body, density is bigger, it is simple to the fixed position of doctor's unrestricted choice screw as required, alleviates support body weight simultaneously.Screw thread nail on support body, is characterized in that screwed hole matches with screw threads.Screw is lock screw nail, is divided into most advanced and sophisticated stage casing and tail end, and tip band screw thread holds skeleton, and stage casing is smooth to be contacted with skin and soft tissue, and tail end has screw thread to pass through combination lock with locking external fixer.
