In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of cervical vertebra Ultrasound intervention practice
Model including the cervical vertebra model coincideing with human anatomic structure, and is wrapped in outside the cervical vertebra model and is used to imitate human body
The colloid of muscle；It is characterized in that：It further include the simulation puncture needle for being practiced；The colloid is insulator, the mould
Quasi- puncture needle is conductor；The cervical vertebra model is by cervical vertebral body model, intervertebral disc of cervical vertebra model, vertebral artery model, cervical nerve root
Model, cervical spinal model composition；The cervical vertebral body model, intervertebral disc of cervical vertebra model are insulator, the vertebral artery model, neck
Nerve root model, cervical spinal model are conductor；After the vertebral artery model, cervical nerve root model, cervical spinal model are in parallel and mould
Quasi- puncture needle is connect with power positive cathode respectively；Further include and the simulation concatenated warning device of puncture needle.It, will in the utility model
Simulation puncture needle and vertebral artery model, cervical nerve root model, cervical spinal model are connected in same circuit, as long as simulation puncture needle
The one above-mentioned model of contact, circuit are switched on, so that the warning device operation connected in circuit, reminds practitioner.
As an improvement：The simulation puncture needle is made by stainless steel, and the colloid is by for silica gel；The cervical vertebra vertebra
Body Model, intervertebral disc of cervical vertebra model are made by PVC plastic；The vertebral artery model, cervical nerve root model, cervical spinal model are by aluminium
Production, outside be enclosed with insulation film.It is to prevent short circuit since three models contact with each other including the reason of insulation film, together
Shi Liyong membrane analogy it is practical puncture when feel.
As a preference, the warning device is alarm lamp.When simulation puncture needle is contacted with cervical vertebra model, power supply is connect
Logical, alarm lamp flashing prompts practitioner.
As a preference, the power supply is dry cell.
As an improvement the simulation, which punctures Aculeata, is provided with a tail cap, the tail cap passes through conducting wire and power supply
Electrode connection；It is provided with pin shaft on the simulation puncture needle tail end side wall, " 7 " word with pin shaft cooperation is provided in the tail cap
Type link slot, the sensible tail cap edge of connection channel opening.The model for simulating puncture needle is varied, passes through split type design
It realizes quick despatch, saves the time.
The utility model is beneficial in that：Cervical vertebra Ultrasound intervention with above structure practices model, structure is true to nature,
It is cheap, easy to use, it can be allowing operator's repeated multiple times carry out neck in the case of simulating patient's neck real structure
The operation of vertebra Ultrasound intervention.
