Description
Technical field
The present invention relates to medical instruments field, specifically a kind of Needle localization work measuring angle for 3 D stereo
Tool.
Background technology
With the development of medical skill, the technology of Minimally Invasive Surgery reaches its maturity.Because Minimally Invasive Surgery is due to damaging little, cost
Less, the advantages of recover fast, is accepted by increasing doctor and patient.
At present, Minimally Invasive Surgery has been successfully applied to clinical medical multiple fields, but Imaging Technology (c- shape arm x-
Ray machine or ct) guided puncture treatment Minimally Invasive Surgery still suffer from technological deficiency.Although, Imaging Technology guided puncture minimally invasive
Operation process is related to two committed steps: one is to be accurately positioned diseased region by Imaging Technology, two be positioning after accurately wear
Pierce to diseased region.Wherein, Imaging Technology can assist to smoothly complete first committed step of operation, that is, be accurately positioned pathological changes
Position.But, for second committed step, how accurately to puncture to diseased region, clinical position lacks effective way.Though
So imaging data can provide accurate puncture angle, but clinician is generally less to carry out actual measurement in skin penetrating point
Determine puncture path afterwards, but according to itself clinical experience and subjective judgment, puncture angle is estimated, lead to puncture successfully
Rate reduces, and causes repeated multiple times puncture or operative failure.
Especially for the affected nerves of patients with trigeminal neuralgia of Trigeminal Semilunar Ganglion Radio frequency thermoset, need losing shape position and horizontal position
Measure puncture angle, to guarantee to puncture smooth entrance oval foramen simultaneously.But, clinician is according to itself clinical experience and subjectivity
Judge puncture angle is estimated, be the major reason leading to operative failure or severe complication.
Cause the less present situation determining puncture path by actual measurement puncture angle of clinician, its reason is mainly
Due to clinically lacking convenience, simple survey tool, thus frequently resulting in actual puncture angle and image in clinical position
Deviation in the puncture angle that data provides.
Content of the invention
It is an object of the invention to provide a kind of Needle localization instrument measuring angle for 3 D stereo, it is in Minimally Invasive Surgery
Lose shape position and horizontal position measures puncture angle provides convenient simultaneously, improve and puncture accuracy, it is to avoid actual puncture angle and image
Deviation in the puncture angle that data provides.
The technical scheme is that a kind of Needle localization instrument measuring angle for 3 D stereo, including locating rack

Structure.
Needle localization instrument in order to the 3 D stereo of the present invention is measured with angle is further described, here to its
Operating procedure during use is described as follows:
Step 1): being first placed on positioning instrument needs the body surface of positioning, under iconography equipment (x-ray or ct)
Positioning；
Step 2): in the anatomical position determining locating rack located lateral bar and vertical positioning strip and body interior diseased region
After relation, labelling body surface puncture position；
Step 3): after the good point of puncture of labelling, the annular slot of the locating rack nearest apart from point of puncture is positioned over puncture
Above point；
Step 4): the fixing axle that bevel protractor is combined the unit is inserted in the annular slot of locating rack, and bevel protractor group is attached together
Put and be fixed on above locating rack；
Step 5): after bevel protractor combination unit fixes, because the right-angle side that ii type bevel protractor is contacted with i type bevel protractor has
Play the role of pointer, therefore ii type bevel protractor along i type bevel protractor scale surface rotate when, ii type bevel protractor and i type angle
The angle indicated by right-angle side of chi 21 contact, that is, lose the puncture angle of shape position；
Step 6): after shape position puncture angle is lost in the right-angle side instruction that ii type bevel protractor is contacted with i type bevel protractor, fixing ii type
Bevel protractor is motionless, continues rotation ii type bevel protractor pointer, and now, ii type bevel protractor microdactylia pin indicates the angle on ii type bevel protractor
Degree, i.e. the puncture angle of horizontal position；
Step 7): keep ii type bevel protractor and pointer position motionless, puncture needle clicks through after skin through puncturing, and relies on pointer
Thick pointer guiding function, keep puncture needle and thick pointer horizontal direction inserting needle, that is, realize the accurate puncture of 3 D stereo；
Step 8): after puncturing success, you can take positioning instrument away.
The invention has the beneficial effects as follows: the Needle localization instrument that this 3 D stereo measures angle shares in row puncture for treating
Minimally Invasive Surgery, with low cost, convenient and practical, it is that in Minimally Invasive Surgery, mistake shape position and horizontal position measure puncture angle provider simultaneously
Just, improve puncture accuracy, reduce operation risk.
