Abstract
The invention relates to a bone nail and provides a scheme for improving an existing clinically used bone nail. The bone nail comprises a nail head and a nail body connected with the nail head, wherein the nail head comprises a hard nail body and a flexible connecting piece used for enabling the nail body and the nail head to swing relatively; and the head and the tail of the flexible connecting piece are respectively connected with the nail head and the hard nail body. The bone nail provided by the invention has the advantages that the traditional rigid nail body is changed into the flexible connecting piece, so that a tiny growth activity space is left for the bone while fixation of a bone is guaranteed, and the bone is promoted to be better and rapidly healed.
Description
Technical field
The present invention relates to the clothing arts of orthopaedics internal fixation operation are and in particular to a kind of nail.
Background technology
Diseased region is typically first carried out clearing up, reduces pressure by traditional bone surgery, then implants nail, passes through
Two adjoining diseased regions directly or with the cooperation of supporting apparatus are fixed by nail, and formation is rigidly connected.As in waist cervical vertebra
Pedicle nail can be implanted adjacent centrum, then is fixedly connected with pitman by fixing operation；And for example during limb fracture, can use
Nail, through bone plate, implants in bone to be plugged into, is similarly formed and rigidly fixes connection.According to up-to-date clinical discovery, adjoining
Diseased region, if can keep after fixation somewhat（About 0.5 millimeter）Relative motion, the quickening of the surface of a wound can be stimulated to fully recover；And
And its healing rate and effect, fix than perfect rigidity, do not have the wound healing effect of relative motion much better.But due to existing
Some nails are mostly based on traditional theory design, metal entirety converted products, and whole nail is in rigidity it is impossible to accomplish small position
Move it is impossible to promote the quickly good healing of diseased region.
Content of the invention
The present invention can only rigidly fix this technical problem of diseased region for nail of the prior art mentioned above,
There is provided a kind of structure simple, produce easy, can widely use it is ensured that diseased region can make the flexibility of trickle relative motion
Linkage section nail.
It employed technical scheme comprise that：A kind of nail, the nail body be connected including ailhead and with ailhead, described nail body includes
There is the flexible connection section that hard is followed closely body body and made opposing oscillatory for nail body and ailhead；The head and the tail two ends of described flexible connection section are divided
Do not connect described ailhead and hard nail body body.
Further, described flexible connection section is spring.
Further, described flexible connection section is medical titanium cable.
Further, described hard nail body body is additionally provided with taper nail tip.
Further, described hard nail body body is additionally provided with hemispherical nail tip.
Further, described hard nail body body is additionally provided with screw thread.
Further, it is welding structure between described flexible connection section and ailhead and hard nail body body.
Further, it is interface arrangment between described flexible connection section and ailhead and hard nail body body.
Further, described flexible connection section is to have the connecting rod of elastic portion, and described elastic portion is provided with hollow slots.
A kind of nail, the nail body be connected including ailhead and with ailhead, described nail is as flexible connection section.
The invention has the beneficial effects as follows：Provide a kind of new flexible nail, conventional rigid nail body is changed over flexibility
Linkage section, while guaranteeing that bone is fixed, reserves trickle vegetative activity space to bone, promotes bone faster and better
Healing；And hardly change nail profile, make original supporting apparatus can continue to use, cost-effective.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Brief description
Fig. 1 is the structural representation of embodiments of the invention one；
Fig. 2 is the perspective view of the embodiment of the present invention two；
Fig. 3 is the structural representation of embodiments of the invention three；
Wherein：1st, ailhead, 2, flexible connection section, 3, hard nail body body, 4, attachment, 5, bone.
Specific embodiment
Embodiments of the invention one as shown in figure 1, a kind of nail, the nail body be connected including ailhead 1 and with ailhead 1, described
Nail body include the flexible connection section 2 that hard is followed closely body body 3 and made opposing oscillatory for nail body and ailhead；Described flexible connection section
2 head and the tail two ends connect described ailhead 1 and hard nail body body 3 respectively.Ailhead 1 is cylinder, also can coordinate for fixing
Ailhead 1 is changed to spherical or hemispherical by the apparatus of nail；The upper surface of ailhead 1 is provided with the tooling hole that cooperation nail installs apparatus,
Lower surface is provided with an installation position with flexible connection section 2 cooperation, and one end of flexible connection section 2 can be with welding or clamping
It is installed in installation position etc. method.In the present embodiment, flexible connection section 2 is a kind of medical titanium cable；In being embodied as, flexibility is even
Connect section 2 and can use spring, the connecting rod being provided with elastic portion can also be changed into, described elastic portion has the hollow out of horizontally set
Groove.Hard follows closely the other end that body body 3 is arranged on flexible connection section 2, and hard nail body body 3 is provided with cooperation flexible connection section 2
Installation position, afterbody be additionally provided with facilitate nail implant bone taper nail tip.During use, it is inserted in the instrument on ailhead 1 with instrument
Hole, controls nail body, hard is followed closely body body 3 and is implanted to behind the precalculated position in bone, ailhead 1 is arranged on fixing bone pin
In medicine equipment, complete the flexibility to bone fixing.
Embodiments of the invention two are as shown in Fig. 2 ailhead 1, in order to coordinate the apparatus of fixing bone, has made hemispherical；Firmly
It is additionally provided with screw thread on matter nail body body 3 outer wall, facilitate nail implantation bone；In order to avoid damaging bone, hard in the present embodiment
The afterbody of nail body body 3 is hemispherical.During use, nail along hard follow closely body body 3 outer wall on be threaded into bone, until
Behind precalculated position, ailhead 1 is arranged in the medicine equipment of fixing bone pin, completes the flexibility to bone fixing..
Embodiments of the invention three, as shown in figure 3, a kind of nail, the nail body be connected including ailhead 1 and with ailhead 1, follow closely body
It is the flexible connection section 2 making opposing oscillatory for nail body and ailhead.Ailhead 1 is fixedly mounted on one end of flexible connection section 2, described
Ailhead 1 is provided with installation flexible connection section 2 installation position.Flexible connection section 2 in the present embodiment is a spring, and ailhead 1 sets
There is cooperation nail that the tooling hole of apparatus is installed.During use, insert the tooling hole on ailhead 1 with instrument, nail is placed into connection
