Primary trigeminal neuralgia is that recurrent exerbation, of short duration and pain tempestuously appear in facial nervi trigeminus management area, has following feature: (1) has the ictal pain at painless interval; (2) without clear and definite nervous system positive sign; (3) trigger point is had; (4) pain is strictly limited in nervi trigeminus domination region, and need get rid of the craniofacial region pain that following disease causes: carcinous prosopodynia, herpes zoster prosopodynia, periodic migrainous neuralgia, atypia nervus facialis characteristic of disease pain etc.
Primary trigeminal neuralgia pathogenesis is failed to understand, Therapeutic Method is various, and standardized therapeutic scheme is not also established.Often select Drug therapy, nerve block for treatment, neural damage treatment, microvascular decompression treatment at present.
The method of recent commonplace application is percutaneous oval foramen puncture semilunar ganglion radiofrequency thermoagulation, and this technology utilizes the coagulation treatment heat under specified temp optionally to destroy pain sensation fiber, reaches the object of pain relieving, and can retain sense of touch and motor function simultaneously.The effect of getting instant result can be reached.
Often adopt Hartel puncture method Ji Qian road puncture method clinically: patient's horizontal position, first reserve 3 points: A point is about 2.5-3.0cm place outside patient's bicker, is the point of puncture of puncture needle herein; B point is 2.5 ~ 3cm place before patient's external auditory meatus, namely before patient's external acoustic pore to paropia line 2/3 with rear 1/3 point of intersection; C point is disease side pupil central authorities.Get point of puncture A inserting needle, puncture needle points to C point on coronalplane, and sagittal plane points to B point.The precision confirming puncture direction and the degree of depth according to CT or DSA is needed in piercing process.The method locates by the anatomic landmark point of human body that to have accuracy not good enough, and effect is unstable, the defect that easily develops complications, and repeatedly has an X-rayed in art, has certain infringement to patient.
Utility model content
The purpose of this utility model is to provide a kind of navigation template for nervi trigeminus navigation puncture, the position of clear and definite oval foramen and structure in software, virtual puncture path, avoids the damage along road nervus vasculairs simultaneously, measure paracentesis depth, thus form puncture guide plate.Pre-set like this puncture path and depth of needle, can guarantee that puncture precisely, puts in place, greatly can improve success rate of operation, reduce patient's damage, have shortening operating time simultaneously, reduce perspective amount of radiation, reduce the advantage of postoperative complication.
The technical solution adopted in the utility model is: a kind of navigation template for nervi trigeminus navigation puncture, its innovative point is: main body is stencil body, described stencil body is for be highly no more than palpebra inferior, and half face shield of facial radian of fitting, half face shield is provided with a length can cover the whole bridge of the nose, and to match nose cup with bridge of the nose radian, nose cup and half face shield one-body molded;
Described half face shield is also provided with one can be fixed on ear, and with the face shield frame of ear radian form fit, described face shield frame and half face shield one-body molded;
The place of described half face shield distance corners of the mouth 20 ~ 30mm is provided with the puncture post for lancet puncture, puncture post and half face shield one-body molded.
Further, described face shield frame is auricle shape, and the length of face shield frame is 1/2 ~ 2/3 of the total arc length of auricle.
Further, described half face shield is half face shield having hollowed out the relevant position contacted with mouth region.
Further, the length of described puncture post is 8 ~ 10mm.
The beneficial effects of the utility model are as follows:
(1) the nervi trigeminus puncture navigation template of this utility model design individuation, the position of clear and definite oval foramen and structure in software, virtual puncture path, avoids the damage to facial vessels and intracranial vessel simultaneously, measures paracentesis depth, thus forms puncture guide plate.
(2) the nervi trigeminus puncture navigation template of this utility model design individuation, is set to 1/2 ~ 2/3 of the total arc length of ear, meets patient comfort by the length of face shield frame, simultaneously also difficult drop-off.
(3) navigation puncture template of the present utility model can improve puncture precision in actual clinical is used, and shortens operating time, reduces perspective amount of radiation, reduces patient's damage.
(4) the nervi trigeminus puncture navigation template of this utility model design individuation, face shield is the face shield having hollowed out the relevant position contacted with mouth region, and mouth region can be protected not carry the baby, and improves patient comfort sense.
(5) the nervi trigeminus puncture navigation template of this utility model design individuation, is set to 8 ~ 10mm by the length of puncture post, according to the average puncture point demand of patient, sets up the puncture post of a suitable length, realize puncture precision.
(6) the nervi trigeminus puncture navigation template of this utility model design individuation, by pre-set puncture path and depth of needle, can guarantee that puncture precisely, put in place, greatly can improve success rate of operation, reduce patient's damage, there is shortening operating time simultaneously, reduce perspective amount of radiation, reduce the advantage of postoperative complication.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described in further details.
Fig. 1 is this utility model overall structure schematic diagram.
Detailed description of the invention
For primary trigeminal neuralgia disease, clinically, normal employing Hartel puncture method Ji Qian road puncture method, the precision confirming puncture direction and the degree of depth according to CT or DSA is needed in piercing process, it is not good enough that location has accuracy, effect instability, the defect easily developed complications, and repeatedly have an X-rayed in art, there is certain infringement to patient.
In order to solve the problem, the nervi trigeminus puncture navigation template of this utility model design individuation, the position of clear and definite oval foramen and structure in software, virtual puncture path, avoids the damage along road nervus vasculairs simultaneously.
