Above embodiment described pair of electrodes that is first electrode 4 and the situation of the second electrode 5 of being provided with, and in order to
Understand the electric current between the multiple diverse locations away from the surface of described open circuit handle 3 of described open circuit head body 9 in more detail
Situation, can arrange multipair electrode, it will therefore be appreciated that electric current, the change of resistance when multipair electrode is respectively at different biological tissue
Change situation, contributes to adjusting nail road more accurately and sets up direction, carry out following closely the foundation in road more accurately, more accurately.
When the present invention uses, as a example by vertebral body operation, medical personnel's hand-held open circuit handle 3, by the open circuit of open circuit head body 9
Head 1, according to pedicle of vertebral arch direction of travel, inserts in patient's pedicle of vertebral arch, can detect the first electrode 4 He by resistance-measuring unit 13
Resistance situation between second electrode 5, can detect the current conditions in testing circuit by current measuring members 7, when wherein one
Individual electrode or two electrodes all proximal or into cortical bone, then due to interelectrode biologic resistance generation significant change, cause electricity
Road curent change, resistance value display shows that resistance value, color-changing light-emitting device make respective color according to curent change in real time
Changing, be black (when being introduced into human body) during resistance maximum, when electrode is in spongy bone, color becomes green, and electrode encounters Cortex Lycii
(resistance reduction) color yellowing during matter, electrode is worn out cortical bone (resistance is the least) color when muscular tissue or Ink vessel transfusing and is become
Becoming redness, medical personnel can do outgoing direction adjust according to concrete prompting.
Pointed to by the passage of apparatus of the present invention, it is ensured that during clinical operation, fix the standard of the screw placement Path Setup of apparatus
Exactness.And the foundation of the big data system of scientific research can be contributed to real time record resistance value.Spinal operation pedicle of vertebral arch can be ensured
The security requirement that screw conduits is set up.
Therefore, the present invention is different by biological tissue between detecting electrode and the different resistance that cause and different electric currents, and will
Resistance sizes and size of current show, thus medical personnel can be adjusted in time according to resistance sizes and size of current,
Thus ensure that following closely road sets up correct, without departing from, it is to avoid patient is caused additional injuries, even jeopardizes patient vitals.
Thus, present inventive concept is novel, and simple in construction is easy to use, and operator can become according to resistance value signal, electric current
Chrominance signal and alarm signal, adjust operation device and enter the direction of sclerotin, sets up the screw placement passage of fixing apparatus, and obtains
Scientific data.Can preferably ensure the security requirement of clinical operation, have bigger using value.
To sum up, the nail road of the display resistance sizes of the present invention set up real-time monitoring device can monitor in real time nail road set up
Journey, once nail road is set up wrong, and medical personnel can be reminded to be adjusted, thus ensures to follow closely the correct foundation in road, it is simple to operation
Operation, it is to avoid screw is put by mistake, reduces and patient is produced additional injuries, it is ensured that operation safety, saves operating time, and design is skilful
Wonderful, simple for structure, easy and simple to handle, manufacture and maintenance cost is low, be suitable to large-scale promotion application.
As can be seen here, the purpose of the present invention the most completely and is effectively achieved.The function of the present invention and structural principle
Being shown the most in an embodiment and illustrate, without departing substantially under described principle, embodiment can arbitrarily be revised.So, this
Bright include based on claim spirit and all variant embodiment of right.
