Handle part is compressed on block.
The fixed U-shaped bone nail of the small sclerite of the utility model, the main position of bone that two nail pins squeeze into fracture is set, using kirschner
Needle sets punch operation in the main position of bone of fracture in advance, and later again by nail pin press-in hole, elastic joint part is pressed on small sclerite
On, small sclerite and main bone are kept fixed by realization, and there is nail pin end to provide better pushing tow position, convenient for U-shaped bone nail
It is pressed into the operation of fracture；Nonrigid connector, which is pressed on, to be realized at small sclerite and will connect between small sclerite and main bone, and elasticity is even
Junctor uses arch design, provides good press force, guarantees that fracture fixation is reliable and promotes fracture healing.
Preferably, two nail pins are in from tail end to tip along phase under the fixed U-shaped bone nail free state of small sclerite
Mutually gather direction inclination to extend.Under structure design, in the fixed U-shaped bone nail of small sclerite in use, the tip of two nail pins
The dome height of the controllable nonrigid connector of the control of angle of release degree, i.e., the elasticity that control nonrigid connector compresses small sclerite are held
Dynamics；Fracture is squeezed into two the vertical of nail pin, nonrigid connector is best to the holding power of small sclerite.
Preferably, two nail pin side walls are equipped with barb, and the barb lateral surface is to connect with nail pin smooth-sided transition
Connect cancave cambered surface.Under structure design, the design of barb guarantees that bone nail fixation is reliable, while the lateral surface of barb is and nail pin
Smooth-sided transition connects cancave cambered surface design, in the main bone for facilitating bone nail indentation fracture.
Preferably, it is described compress handle part by three in the width direction distribution compress item and constitute, and middle position compresses
Item compresses power to the elasticity of small sclerite and compresses power to the elasticity of small sclerite greater than the item that compresses of two sides.Under structure design,
Center, which compresses power greater than two sides, so that more solid and reliable to the fixation of small sclerite, to be realized to small sclerite.
Preferably, the item that compresses in the middle position compresses item along what protrusion direction was higher by two sides.Under structure design, in
Between the item that compresses small sclerite is carried out compressing fixation in advance, it is then intermediate to compress that item gradually pressurizes and successive two sides are supported
Press strip pressurizes to small sclerite, so that the fixation of small sclerite is more solid and reliable.
The utility model is further described with reference to the accompanying drawing.

Specific embodiment
Referring to attached drawing 1~4, a kind of fixed U-shaped bone nail of small sclerite disclosed by the utility model, including two nail pins 1 with
And the nonrigid connector 2 of two nail pins 1 of connection, two 1 side walls of nail pin are equipped with barb 11,11 lateral surface of barb be with
1 smooth-sided transition of nail pin connects cancave cambered surface 111, and the design of barb guarantees that bone nail fixation is reliable, while the outside of barb
Face is that cancave cambered surface design is connect with nail pin smooth-sided transition, in the main bone for facilitating bone nail indentation fracture；Nail described in two
1 tail end of foot has been laterally extended end 12, and 2 both ends of nonrigid connector are respectively fixedly connected in the end of two nail pins 1 12, end
12 tops have the concave surface 121 cooperated for thimble on bone nail pressing in tool, and nonrigid connector 2 is along nail pin 1 tip direction protrusion
Arch, have pressure holding in compressing handle part 21 on small sclerite in the middle part of nonrigid connector 2, the two sides for compressing handle part 21 are
The linking arm 22 being connect with the end 12.
Further setting, two nail pins 1 are under the fixed U-shaped bone nail free state of small sclerite in from tail end to point
End extends (as shown in Figure 4) along direction inclination is mutually gathered.In the fixed U-shaped bone nail of small sclerite in use, the point of two nail pins
The dome height of the controllable nonrigid connector of the control of opening angle is held, that is, controls the elasticity that nonrigid connector compresses small sclerite
Holding dynamics；Fracture is squeezed into two the vertical of nail pin, nonrigid connector is best to the holding power of small sclerite.
It is described compress handle part 21 by three in the width direction distribution compress 21-1,21-2, a 21-3 and constitute, and interposition
The 21-2 that compresses set compresses power to the elasticity of small sclerite and compresses 21-1,21-3 to the elasticity of small sclerite greater than two sides
Compress power.Center, which compresses power greater than two sides, so that more solid and reliable to the fixation of small sclerite, to be realized to small sclerite.It is described
The 21-2 that compresses in middle position compresses 21-1,21-3 along what protrusion direction was higher by two sides；In reaching while design in this way
Between the item that compresses of position power is compressed to the elasticity of small sclerite power is compressed to the elasticity of small sclerite greater than the items that compresses of two sides, in
Between the item that compresses small sclerite is carried out compressing fixation in advance, it is then intermediate to compress that item gradually pressurizes and successive two sides are supported
Press strip pressurizes to small sclerite, so that the fixation of small sclerite is more solid and reliable.
The fixed U-shaped bone nail of the small sclerite of the utility model, the main position of bone that two nail pins squeeze into fracture is set, using kirschner
Needle sets punch operation in the main position of bone of fracture in advance, and later again by nail pin press-in hole, elastic joint part is pressed on small sclerite
On, small sclerite and main bone are kept fixed by realization, and there is nail pin end to provide better pushing tow position, convenient for U-shaped bone nail
It is pressed into the operation of fracture；Nonrigid connector, which is pressed on, to be realized at small sclerite and will connect between small sclerite and main bone, and elasticity is even
Junctor uses arch design, provides good press force, guarantees that fracture fixation is reliable and promotes fracture healing.
