Description
Technical field
The present invention relates to orthopedic medical device technical field, and in particular to one kind is used to fix in bone, is particularly suitable for people
A kind of calcaneum ladder steel plate of the body with bone fixation.
Background technology
Generally, the long axis angle of the long axis of human tibia and calcaneum is 0-15 °, when shin bone long axis with
Surgical intervention, the common disease of calcaneum ladder steel plate are then needed when the long axis angle of calcaneum is more than 20 ° or when angle is negative：
Talipes cavus, flat foot, congenital hypodevelopment and fracture of calcaneus healing deformity.The usual way of operation：1. calcaneum is being needed
Position block, cause artificial fracture；2. it is fixed behind position needed for block two sections are adjusted to.
Nail and hone lamella, deficiency in use are used during above-mentioned with the operative treatment disease of prior art mostly：Bone
Nail is during screw-in, it is impossible to which accurate control screws in angle, and easily occurs osteoporosis；Nail holds in actually walking
Easily occur to loosen and come off；Screw not enough, is main weight-bearing areas below talocalcaneal joint, uses existing spiral shell at the top and bottom of calcaneum
Nail and internal fixation plate design, often only have one piece of screw space herein；Many regions for placing screw, its bone density is low, holds
The problems such as easily there is nail pulling；The design of internal fixation plate bearing partition shape is unreasonable, its gravity conduction orientation and bone trabecula bearing of trend
Mismatch.Disadvantages described above causes calcaneum is postoperative to be unable to early loading.Therefore, it is very necessary to develop a kind of calcaneum ladder steel plate
, it is the best way for overcoming prior art defect.
The content of the invention
The technical problems to be solved by the invention be to provide it is a kind of simple to operate, it is fixed, infection can be prevented effectively from,
Flexibly and easily, a kind of calcaneum ladder steel plate for being conducive to patient's calcaneum to recover.
The present invention solve the technical scheme that is used of seven technical problem for：A kind of calcaneum ladder steel plate, including backboard 1, the back of the body
The middle part of plate 1 is provided with stepped bending 2, and 1 point by backboard of stepped bending 2 is two regions up and down, up and down two region height differences
For 5-10mm, four angles of backboard 1 are provided with pin nail 4 is respectively equipped with, and the tip of pin nail 4 is in the same plane；It is in area on backboard 1
Two pin nail 4 in domain is parallel to each other, and inclination angle is tilted down, and the two pin nail 4 for being in 1 time region of backboard is parallel to each other, and together
Inclination angle is inclined upwardly；Arc bent area 3 is provided between backboard 1 and pin nail 4.
It is in 60-80 degree to set transition zone between backboard 1 and pin nail 4 to make backboard 1 and pin follow closely the angle between 4.
Backboard 1, pin nail 3 are formed in one, and its material is medical grade Ultimum Ti, aluminium alloy or stainless steel.
The contact surface of pin nail 4 and bone is provided with anti-skid structure.
Anti-skid structure is thrust 5, rectangular in cross-section, triangle or the semicircle of thrust 5.
Anti-skid structure on pin nail 4 is the anti-skidding groove 7 being evenly distributed.
Anti-skidding groove 7 is transversely arranged or longitudinal arrangement.
The width 15-25mm of backboard 1.
It is 20-30mm that pin, which follows closely 3 length,.
Backboard 1 is provided with least two through hole 4, and through hole 4 is evenly and symmetrically distributed on backboard about 1 on two regions.
The forward projection of backboard 1 is in I-shaped or rectangle.
The beneficial effects of the present invention are：The present invention is made using Ultimum Ti, according to material in 0 DEG C to 40 DEG C temperature
The characteristic of memory deformation is produced in the range of degree, the special construction form of the present invention is designed by fracture fixation engineering science structural requirement,
Calcaneum ladder steel plate, by two nail pin expansion of calcaneum ladder steel plate, is directly inserted and suffered from bone in 0 to 5 DEG C of brine ice
Afterwards, produced dynamic on calcaneum ladder steel plate with 40 DEG C of hot salt brine soak using Ultimum Ti sheet material geneva effect and added
Pressure, pressurization nature, soft holds device, bone and is integrated, solid and reliable.The present invention is the back rank of fixed arc and special height
Ladder design is more beneficial for bone grafting, loaded reset and fixation, and fixator is placed directly within subcutaneously, both easy to operate without outer fixation, again
Infection is avoided, is conducive to the activity of patient's early postoperation and the recovery for suffering from bone.
Backboard about 1 two region heights difference be 5-10mm, can effectively fit human body, improve success rate of operation.The back of the body
60-80 degree angles between plate 1 and pin nail 3 are optimum fixed angles, are especially suitable for Ultimum Ti, and restore in deformation
After can also make pin follow closely 3 in the same plane.The width of backboard 1 can be adjusted in 15-25mm best results according to the injury condition of the injury
It is whole.It is 20-30mm best results that pin, which follows closely 3 length, can be adjusted according to the injury condition of the injury.
For the patient, old man, child of osteoporosis, the product with anti-skidding groove 7 is applicable, adult's sclerotin is solid
Patient is applicable the product with thrust 5, and the postoperative patient for needing long-term bed is applied to the product without anti-skid structure.
