As shown in fig. 1 to 3, a protector for open fracture treatment includes a fixing pin 10 for inserting into a bone of an affected part to fixedly connect the bone, and the fractured bone is fixed by the fixing pin 10. The driving position of the fixing nail 10 is the same as that of the external fixator, and generally the fixing nail 10 is driven and fixed from the inner side after the fracture of the calf or forearm, while the fixing nail 10 is driven and fixed from the outer side after the fracture of the thigh or upper arm.
This protector still includes and is used for the cover to locate the limbs affected part and form 5 ~ 20mm annular gap's outer lag 20 with the limbs top layer, be equipped with adaptation district 21 along its axial on the outer wall of outer lag 20, adaptation district 21 is including inside sunken rectangle heavy groove, a plurality of intervention hole 211 has been seted up on the rectangle heavy groove, intervention hole 211 is the bar hole structure of arranging along outer lag 20 axial, be located the rectangle heavy inslot all around in the hole 211 outside and form extrusion portion 212, the surface of extrusion portion 212 is metal level 213.
The staple 10 is T shape structure, has spacing portion and the vertical intervention portion that can penetrate the hole 211 that intervenes that the level set up, the lower extreme of spacing portion is personally submitted the arcwall face that can laminate mutually with extrusion 212 surface, be equipped with the magnetic adsorption layer 11 that can adsorb on metal level 213 on the arcwall face.
The protective device can replace a conventional external fixing frame and is used for treating open fracture. When using, earlier overlap outer lag 20 in the affected part of limbs, then rotatory adjustment outer lag 20, make adaptation district 21 correspond with the affected part, and guarantee to keep certain annular interval as far as possible between outer lag 20 and the limbs, then pass intervention hole 211 with the portion of interveneeing of staple 10, and adjust the axial position of staple 10 along interveneeing hole 211, then use equipment is squeezed into the staple 10 into the bone in, and make spacing portion and extrusion portion 212 laminate mutually with the help of the absorption of magnetic force adsorbed layer 11 to metal level 213, realize that staple 10 is fixed to outer lag 20, can make and keep certain annular interval between outer lag 20 and the limbs through the length of squeezing into staple 10.
The outer protective sleeve 20 of the protective device wraps the affected part, the fixation nail 10 is inserted into the bone of the affected part, and the outer protective sleeve 20 is axially and radially positioned by magnetic adsorption, so that the infection and inflammation of the affected part caused by dust (bacteria) or water can be reduced under the condition of ensuring air permeability; the outer protecting sleeve 20 and the fixing nails 10 are mutually fixed, the outer protecting sleeve 20 also plays a role in connecting and fixing a plurality of fixing nails 10, the overlong protruding length of the fixing nails 10 is avoided, the contact probability of external force and the fixing nails is reduced, and the intervention stability of the fixing nails 10 is improved; in addition, the intervention hole 211 is a strip-shaped hole, so that the accuracy of the intervention position of the fixing nail 10 is improved.
The diameter of the sleeve formed by the outer protective sheath 20 is dependent on the size of the patient, since the patient may have different fat and thin body shapes. In order to facilitate the use of the device, the outer protective cover 20 is made of a polymer splint made of a plurality of layers of polymer fibers impregnated with polyurethane or polyester. The polyurethane material is a segmented copolymer containing soft segment, has higher plastic capability, can be shaped into a shape fitting with limbs in 75 ℃ water, has high curing speed, hard strength and light weight after curing, generally has no stimulation to affected parts, and does not generate anaphylactic reaction. And the adaptation zone 21 is located on an arc-shaped aluminum plate 22 embedded in the outer protective sleeve 20, and the thickness of the outer protective sleeve 20 is the same as that of the arc-shaped aluminum plate 22. The adaptation district 21 is because during the nailing, staple 10 need be spacing by extrusion portion 212, therefore adaptation district 21 need can bear great power, so imbed arc aluminum plate 22 on polymer splint material to improve the life of the device.
In order to improve the holistic structural strength of outer lag 20, it is fixed that arc aluminum plate 22 and outer lag 20 adopt the lapped form, arc aluminum plate 22 have first overlap joint portion 214 all around, outer lag 20 and the lapped position of arc aluminum plate 22 have with first overlap joint portion 214 assorted second overlap joint portion 201, in addition in order to guarantee that arc aluminum plate 22 imbeds whole inner wall in back smooth, improve the comfort level that the patient wore, thickness after first overlap joint portion 214 and the overlap joint of second overlap joint portion 201 is the same with outer lag 20's thickness.
Specifically, after the first overlapping portion 214 overlaps the second overlapping portion 201, a connection barb 215 capable of being embedded into the second overlapping portion 201 may be fixed to the first overlapping portion 214, so as to achieve overlapping fixation. The first strap 214 and the second strap 201 may be adhesively fixed.
In order to increase the friction between the metal layer 213 and the magnetic force absorption layer 11, so that the metal layer 213 and the magnetic force absorption layer 11 are not easy to slide axially, the outer surface of the metal layer 213 has friction lines for increasing the friction between the metal layer and the magnetic force absorption layer 11.
In order to prevent the driving of the fixing nail 10 from being affected by the magnetic force of the magnetic adsorption layer 11, the fixing nail 10 adopts a split structure and comprises a positioning sleeve 12 and a carbon fiber rod 13, the carbon fiber rod 13 is in a screw or screw structure, the positioning sleeve 12 is in a T-shaped structure, and a T-shaped through hole matched with the carbon fiber rod 13 is formed in the axis of the positioning sleeve 12. In use, since the magnetic force adsorption layer 11 is provided on the positioning sleeve 12, the positioning sleeve 12 is first mounted at a suitable position in the insertion hole 211 and fixed to the pressing portion 212 by adsorption, and then the carbon fiber rod 13 is inserted through the positioning sleeve 12 and driven into the bone with a tool. Thus, when the carbon fiber rod 13 is driven, the carbon fiber rod can be driven at any angle without being affected by the magnetic force.
Further, in order to improve the air permeability of the affected part, especially in summer, and prevent the affected part from rotting, a plurality of air holes 23 are uniformly distributed on the lower outer protective sleeve 20.
The above is only a preferred embodiment of the invention, and any simple modifications, variations and equivalents of the invention may be made by anyone in light of the above teachings and fall within the scope of the invention.
