Description
Technical field
The present invention relates to medical instruments field, specifically a kind of Needle localization instrument taken measurement of an angle for 3 D stereo.
Background technology
Along with the development of medical skill, the technology of Minimally Invasive Surgery reaches its maturity.Due to Minimally Invasive Surgery due to damage little, cost less, recover the advantage such as fast, by increasing doctor and patient accept.
At present, Minimally Invasive Surgery has been successfully applied to clinical medical multiple field, but the Minimally Invasive Surgery of Imaging Technology (C-arc X-ray machine or CT) guided puncture treatment still exists technological deficiency.Although the minimal invasive surgical procedures of Imaging Technology guided puncture relates to two committed steps: one is accurately locate diseased region by Imaging Technology, two is accurately puncture to diseased region behind location.Wherein, Imaging Technology can assist first committed step completing operation smoothly, namely accurately locates diseased region.But for second committed step, namely how accurately puncture is to diseased region, and clinical position lacks effective way.Although imaging data can provide puncture angle accurately, but clinician is usually less determines puncture path after skin penetrating point carries out actual measurement, but according to self clinical experience and subjective judgment, puncture angle is assessed, cause puncture success rate to reduce, cause 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 to measure puncture angle in mistake shape position and horizontal position, to guarantee that puncture enters oval foramen smoothly simultaneously.But clinician assesses puncture angle according to self clinical experience and subjective judgment, it is the major reason causing operative failure or severe complication.
Cause the less present situation being determined puncture path by actual measurement puncture angle of clinician, its reason is mainly owing to lacking convenience, simple survey tool clinically, thus deviation appears in the puncture angle usually causing the actual puncture angle in clinical position and imaging data to provide.
Summary of the invention
The object of this invention is to provide a kind of Needle localization instrument taken measurement of an angle for 3 D stereo, measure puncture angle simultaneously provide convenience for losing shape position and horizontal position in Minimally Invasive Surgery, improving puncture accuracy, there is deviation in the puncture angle avoiding actual puncture angle and imaging data to provide.
Technical scheme of the present invention is: a kind of Needle localization instrument taken measurement of an angle for 3 D stereo, comprise locating rack and bevel protractor combination unit, described locating rack is that soft metal material is made, be made up of several located lateral bar and several vertical positioning strip square crossing, each located lateral bar and square crossing place of vertical positioning strip have an annular slot structure, described bevel protractor combination unit is by I type bevel protractor, II type bevel protractor, rotating shaft and fixed axis are formed, described I type bevel protractor is made up of hard transparent plastic material, scale range is 90 °, described II type bevel protractor is by bevel protractor, rotating ring and pointer are formed, described bevel protractor is made up of hard transparent plastic material, scale range is 90 °, II type bevel protractor right angle end is fixed in described rotating ring one end, the microdactylia pin front end of one end concatenation pointer, described pointer is made up of microdactylia pin and thick pointer, described microdactylia pin is positioned at the first half of pointer, be connected with rotating ring, can be that the center of circle rotates with rotating ring, described thick pointer is positioned at the latter half of pointer, energy guided puncture direction, I type bevel protractor right angle end is fixed in described rotating shaft one end, one end connects II type bevel protractor, described I type bevel protractor becomes vertical bit architecture with II type bevel protractor, described II type bevel protractor can be that the center of circle rotates with rotating shaft, described fixed axis is hollow cylindrical-shaped structure, one end is fixed on bottom I type bevel protractor, the annular slot structure that locating rack can be inserted in one end is fixed on locating rack top, described locating rack and bevel protractor combination unit are dismountable structure, described bevel protractor combination unit is integral type structure.
In order to the Needle localization instrument taken measurement of an angle to 3 D stereo of the present invention is further described, here its operating procedure is in use described as follows:
Step 1): first orientation tool is placed on the body surface needing location, locates under iconography equipment (X-ray or CT);
Step 2): after the anatomical position relation determining locating rack located lateral bar and vertical positioning strip and body interior diseased region, labelling body surface puncture position;
Step 3): after the good point of puncture of labelling, the annular slot of locating rack nearest for distance point of puncture is positioned over above point of puncture;
Step 4): the fixed axis of bevel protractor combination unit is inserted in the annular slot of locating rack, bevel protractor combination unit is fixed on above locating rack;
Step 5): after bevel protractor combination unit fixes, the right-angle side contacted with I type bevel protractor due to II type bevel protractor has the effect of pointer, therefore when II type bevel protractor rotates along I type bevel protractor scale surface, angle indicated by the right-angle side that II type bevel protractor contacts with I type bevel protractor 21, namely loses the puncture angle of shape position;
Step 6): after the right-angle side that II type bevel protractor contacts with I type bevel protractor indicates and loses shape position puncture angle, fixing II type bevel protractor is motionless, continues to rotate II type bevel protractor pointer, now, angle on II type bevel protractor microdactylia pin instruction II type bevel protractor, i.e. the puncture angle of horizontal position;
Step 7): keep II type bevel protractor and pointer position motionless, puncture needle enters after skin through point of puncture, relies on the guiding function of thick pointer of pointer, keeps puncture needle and thick pointer horizontal direction inserting needle, namely realizes the accurate puncture of 3 D stereo;
Step 8): puncture successfully, can orientation tool be taken away.
The invention has the beneficial effects as follows: the Needle localization instrument that this 3 D stereo takes measurement of an angle share the Minimally Invasive Surgery in row puncture for treating, with low cost, convenient and practical, measure puncture angle simultaneously provide convenience for losing shape position and horizontal position in Minimally Invasive Surgery, improve puncture accuracy, reduce operation risk.
