Abstract
The invention discloses an in-vivo fixing device for the department of orthopaedics. The device comprises a bone fracture plate made of a ceramic material, a power supply module arranged inside the bone fracture plate, and two electrodes led out of the bone fracture plate and electrically connected with the power supply module. By arranging the electrodes on the bone fracture plate and implanting the electrodes into the fracture part of a patient together with the bone fracture plate, fixed-point electrical stimulation treatment of the fracture part is achieved, treatment effect is improved, and limitation on the time and area of fracture electrotherapy is broken.
Description
Technical field
The present invention relates to orthopedic medical device field, particularly relate to a kind of orthopaedics body inner fixing device promoting knitting.
Background technology
Existing tangible proof shows that electricity irritation has the effect obviously promoting union of fracture.Galvanism coordinates various fixed form also to achieve good clinical effectiveness in the treatment of fracture.Galvanism mode conventional is clinically by pasting electrode on patients with fractures's limbs, external power supply unit is adopted to be energized to suffering limb, this therapeutic modality obviously has the restricted of time and region, first patient can not because the electronic stimulation of short time and the equipment of purchasing price costliness, the place of therefore treating can only be selected in hospital, in addition, even if patient have purchased electrotherapy apparatus voluntarily, because electrotherapy apparatus carries inconvenience, therefore also can not apply medical diathermy equipment in patient moving process.
Consider the problems that electrotherapy mode of fracturing at present exists, the present inventor devises a kind of orthopaedics body inner fixing device, can solve the problem well.
Summary of the invention
In view of this, the object of this invention is to provide a kind of orthopaedics body inner fixing device, the fixed point electronic stimulation for fracture can be realized by this orthopaedics body inner fixing device, breach time and the region restriction of fracture electrotherapy simultaneously.
The present invention realizes above-mentioned purpose by following technological means:
Orthopaedics body inner fixing device of the present invention, comprises the blade plate be made up of ceramic material, the supply module being arranged on blade plate inside and is drawn out to blade plate outside and two electrodes be electrically connected with supply module.
Further, described blade plate is provided with the pressurization hole or lock hole that coordinate with built-in nail, described electrode is embedded on the hole wall of pressurization hole or lock hole.
Further, have timing power supply circuit in described supply module, described timing power supply circuit is used for the time of circuit communication between control electrode and supply module.
Further, the described supply module wireless charging receiver that comprises chargeable battery and be connected with battery.
Further, described wireless charging receiver adopts electromagnetic induction or electromagentic resonance principle to receive electric energy, and electric energy is flowed to battery charges.
Further, the plate face of described blade plate side is provided with groove, described supply module is arranged in described groove, and the notch place of groove is sealed by medical plastic.
Further, described blade plate adopts calcium phosphorus porous ceramic film material to make.
Further, the surface of described blade plate is provided with the slow release layer containing skeletal growth factor and slow releasing pharmaceutical.
