It is respectively formed the first circuit either second servo loop or tertiary circuit.Wherein, the first indicator light 491 is set on the first circuit, is used
Pia mater 44 whether is touched in instruction puncture needle 48；Second indicator light 492 is set on second servo loop, is used to indicate puncture needle 48
Whether transverse process 45 is touched；Third indicator light 493 is set on tertiary circuit, is used to indicate whether puncture needle 48 touches lumbosacral region
Nerve 46.Three indicator lights can play the role of guided puncture.Master control switch 47 can be substituted with the attaching plug 41 in Fig. 1,
Play the role of controlling on/off.External power supply 43 can be direct current or alternating current.
Canalis spinalis 13 when in use, is inserted into air bag 12 by the simulator that backbone is punctured under the ultrasound in the embodiment first
It is interior, then air bag 12 is inserted into spine model 100, air charging system 123 is then operated and inflates, until canalis spinalis 13 is solid securely
Due in spine model 100.Then, power on, puncture position is looked under ultrasonic imaging by puncture needle 48.If by soft
Meninx 44 then when puncture needle 48 is punctured to air bag 12, punctures practitioner and has the sense that falls through, to which simulation is worn as target is punctured
The needle point of pricker 48 punctures into the feeling of ligamentum flavum, and when further test touches pia mater 44 to needle point, first refers at this time
Show that lamp 491 lights, instruction punctures successfully.In piercing process, if being punctured to transverse process 45 or lumbosacral region nerve 46, accordingly refer to
Show that lamp can light, is guided to play the role of puncturing.It certainly, also can be by transverse process 46 or lumbosacral region nerve 46 as puncture mesh
Mark is practiced, and is played in the process for that can play the role of instruction as the part for puncturing target.
It punctures in practice, impregnates substance 3 due to that can penetrate, puncture air bag 12, to influence to puncture the effect of practice again.
Substance 3 is impregnated at this point, can heat so that it is again moulding to impregnate substance 3.For air bag 12, air bag 12 can be rotated an angle,
Switch different puncture positions, to not influence to puncture the effect of practice again.When air bag 12 is due to repeatedly puncturing, can not use
When, directly air bag 12 can be taken out, re-replace air bag 12, or integral replacing is all done to air bag 12 and canalis spinalis 13.Certainly,
Canalis spinalis 13 can be only replaced in primary replace.
The simulator that backbone is punctured under ultrasound in the application, movably fills due to being equipped with air bag 12 including canalis spinalis 13
It fills in in the model ontology 11, on the one hand due to the presence of air bag, the sense that falls through when wearing out ligamentum flavum can be simulated；Another party
The switching in face, puncture position is simple and convenient so that puncturing practice can repeatedly be continued for effectively puncturing practice, also, gas
The replacement of capsule 12 and canalis spinalis 13 is simple and convenient, substantially increases practice efficiency, while reducing cost.
