Abstract
The hollow screw of screw thread the utility model discloses a kind of both sides of sophisticated self tapping are ruptured with seriality.The hollow screw includes following closely body (1), the head of a nail (2), nail tip (3)；There is symmetrical seriality fracture screw thread (11), nail tip (3) outer surface there is seriality screw thread (31) for nail body (1) outer surface both sides.Boring of the present utility model, can squeeze into inside sclerotin along the fixed-direction of Kirschner wire by sophisticated self tapping structure, this structure can effectively solving early stage osteoarthritis tibial plateau understrressing so that the pathological changes subsided.The plane that there is not screw thread distribution both sides plays good supporting role, and symmetrical seriality screw thread is combined closely with sclerotin and reaches fixed effect.
Description
Technical field
This utility model belongs to technical field of biomedical materials, is related to one kind and there is sophisticated self tapping structure, and both sides carry
The hollow screw of seriality screw thread.
Background technology
In early stage osteoarthritis, ability that tibial plateau two ends meet with stresses is simultaneously unbecoming.Because on the outside of tibial plateau
There is peroneal sustaining, its stress ability to bear is relatively strong.But medial side of tibial plateau is supported only according to itself sclerotin, stress bears energy
Power is relatively weak.Early stage Human Osteoarthritis, often with hyperosteogeny so that lateral stress ability to bear phase inside and outside tibial plateau
Difference is increasing.In the course of time can then cause tibial plateau to subside, cause even more serious pathological changes, great pain is brought to patient
Bitter.
Titanium alloy is used widely in human body surgical implant, such as one of bio-medical Metallic Functional Materials
Mouth cavity planting body, Cranial defect patching material, pseudarthrosis implant etc..Which has nontoxic, light weight, good biocompatibility and corrosion resistant
Corrosion and with the elastic modelling quantity more mated with human Cortex's bone.At Titanium Alloy Screw application to tibial plateau, by interior
Side is squeezed into, and can play good support effect, and prevention early stage osteoarthritis tibial plateau subsides generation.
Content of the invention
The purpose of this utility model be to provide a kind of tip can self tapping hollow screw of the both sides with seriality screw thread.
This utility model can be incoming along Kirschner wire direction by boring structure, by sophisticated self tapping and both sides seriality screw thread
Structure, squeezes into inside sclerotin, reaches the supporting role of medial side of tibial plateau part.
To achieve these goals, this utility model employs following technical scheme：
This utility model provide a kind of tip can self tapping both sides with seriality screw thread hollow screw, described hollow
Screw includes following closely body (1), the head of a nail (2), nail tip (3)；Nail body (1) the outer surface both sides have symmetrical seriality fracture
There is seriality screw thread (31), nail body (1) to be had hollow with the nail tip (3) for screw thread (11), nail tip (3) outer surface
Inner chamber, the inner chamber of nail tip (3) lower end outlet and described nail body (1) inner space, the head of a nail (2) are provided with hole
Groove (21), hole slot (21) lower end and the inner space for following closely body (1).
Further, nail tip (3) are round table-like self tapping structures.
Further, described hole slot (21) are in interior hexagon.
Further, the hollow screw adopts titanium alloy to be prepared from for raw material.
Hollow screw of the present utility model can be prepared from using 3D printing or casting.
Advantage of the present utility model and beneficial effect：
Hollow screw simple structure of the present utility model, reasonable in design.Boring of the present utility model, can be along kirschner
The fixed-direction of pin, squeezes into inside sclerotin by sophisticated self tapping structure.The symmetrical hand of spiral in both sides is hung down with tibial plateau
Directly, the relatively flat plane in another both sides is parallel with tibial plateau, and this structure can effectively solving early stage osteoarthritis tibial plateau
Understrressing is so that the pathological changes subsided.The plane that there is not screw thread distribution both sides plays good supporting role, and symmetrical
Seriality screw thread is combined closely with sclerotin and reaches fixed effect.
