Description
Technical field
This utility model relate to a kind of Maxillary region based on 3D printing technique puncture guider, belong to Medical Image Processing and
Application.
Background technology
Cranial nerve pain (such as trigeminal neuralgia, glossopharyngeal neuralgia, sphenopalatine neuralgia etc.) is typical neuropathic pain,
Sharp ache during outbreak, has a strong impact on the daily life of patient, and therefore What is more commits suicide.
Generally, cranial nerve pain patient can obtain certain control by Drug therapy, but when disease progression or because of each
Kind of reason can not Drug therapy time, minimally-invasive treatment is the common choice of doctors and patients.Radio frequency thermoset is because having the most in the recent period and remote
Phase curative effect and become the most the most frequently used Minimal invasive procedures, it be through Maxillofacial derma by radio frequency puncture needle enter cranium inside and outside
, there is choosing at the positions such as target area (oval foramen, circular hole, jugular foramen, stylomastoid foramen etc.) neuroganglion, nerve root, nerve trunk
Destroying the nerve fiber of corresponding afflicted areas with selecting, then reach the purpose of longer-term treatment cranial nerve pain, precisely puncturing is cranium
The co-route of the minimally-invasive treatments such as nerve block, radio frequency and balloon compression and committed step.
Cranial nerve minimally-invasive treatment target area (as dry in oval foramen Trigeminal Semilunar Ganglion, circular hole maxillary nerve, jugular foramen tongue
Nervus pharyngous goes out at cranium) distributed about there is important organizational structure, and also individual variation is relatively big, therefore requires puncture high.
Under traditional mode, doctor carries out body surface Anatomical orientation according to working specification, punctures by personal experience completely, often needs anti-
Multiple puncture and Fluoroscopy location.Puncture and not in place can not reach therapeutic effect；Repeated localised puncture also can cause ridge hemorrhage, blind, complete
The serious adverse reactions such as marrow anesthesia；Image location adds doctors and patients' radiation exposure repeatedly, also occupies limited medical treatment money simultaneously
Source.3D prints Personalized Navigation system can realize minimally-invasive treatment individuation and precision, relatively other location technology learning curve
Shorter, front-end fee put into lower, replicability is higher.
At present, Chinese patent literature CN104287839A discloses the navigation template that structure is similar with CN204192714U,
Template above utilizes 3D technology to print the face shield of a laminating patient facial region, above has the puncture post for puncturing, and this face shield leads to
Cross nose cup, face shield frame is fixed on face.This navigation template mainly utilizes bridge of the nose gill root location, fixes, therefore face shield area
Relatively big, the time-write interval is longer, relatively costly.It addition, because there being the interference factors such as hair, ear is the most easy to attach；Large stretch of
Face shield is fitted in face can be to the sensation of people's discomfort；For the people that subcutaneous fat is thicker, facial expression also results in face shield
Mobile, thus affect location.This formwork structure not consolidation, in transportation and disinfecting process, easily deforms and affects
Its accuracy.
Utility model content
The purpose of this utility model is to provide a kind of Maxillary region based on 3D printing technique and punctures guider, and this device can be auxiliary
Help and carry out safety, accurately Maxillary region puncture.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of Maxillary region based on 3D printing technique is worn
Thorn guider, the integrated apparatus printed for 3D, including facing and at least one puncture post, also include for even
Connect facing and puncture the attachment means of post, described puncture post setting through hole, for puncturing hole.
Described attachment means is made up of the fixing bar being connected with facing and the guide post being connected with puncture post, and described fixing bar quantity is one
Root or several, every fixing bar can connect one or more guide post, every guide post can set one or more and puncture post,.
Described attachment means is made up of the fixing bar being connected with facing and the guide post being connected with puncture post, and described fixing bar quantity is one
Root or several, every fixing bar can connect one or more guide post, and the guide post of more than two may be connected to same puncture post
On,.Described facing is upper tooth facing, can entangle upper tooth 4-6.
Described facing is occlusion facing, is engaged by upper lower tooth simultaneously and plays fixation.
Described puncture post has two, and the puncturing hole of two puncture posts is positioned at same straight line.
Described puncture post more than two, any two of which punctures the puncturing hole of post and is positioned at same straight line, or is not positioned at same
Straight line.
The invention also discloses above-mentioned Maxillary region based on 3D printing technique and puncture the preparation method of guider, its
Step includes:
A, patient's maxillofacial region including tooth is carried out CT thin slice scan, obtain scan data；
B, scan data is imported medical science modeling software, set up the 3 D digital model of Maxillary region skeleton, and mark out
The target location that may treat, this 3 D digital model includes the tooth mould of patient；
D, according to three-dimensional digit model, the simulation being established to target location with software most preferably punctures needle track and paracentesis depth,
The optimal needle track that punctures needs to avoid the important blood vessels along road and nerve；
E, the optimal puncture needle track data of the 3 D digital model of patient and simulation is imported in software, generate claim
Puncture guider model described in 1 so that puncturing hole is corresponding with the optimal puncture needle track of simulation；
F, the puncture guider data of generation are imported 3D printing equipment print.
Maxillary region based on 3D printing technique of the present utility model punctures guider and is fixed on upper tooth by facing, is difficult to move
Position, more accurate positioning.Multiple puncturing hole can be set on same guider simultaneously, carry out Mutiple Targets (oval foramen, circle
Hole, jugular foramen, stylomastoid foramen etc.) puncture or puncture (such as the approach under socket of the eye, zygomatic arch of circular hole) with target spot difference path,
Improve success rate of operation further.Furthermore it is possible to design two guide posts on the fixing bar of same attachment means, make two
The puncturing hole puncturing post is positioned at same straight line, improves the degree of accuracy puncturing needle track further；Also can set on same guide post
Put more than or equal to two puncture posts, to meet Mutiple Targets puncture needs.Jaw face based on 3D printing technique of the present utility model
Portion punctures guider, and compared with described in background technology two kinds, navigation template stability is strong, consumptive material is few, the time-write interval is short, cost performance
Height, and more accurate positioning, range is more extensive, can carry out the puncture of multiple cranial nerve (such as nervi trigeminus, glossopharyngeum
Nerve, nervus facialis, nervi pterygopalatini etc.).This navigation system can be not only used for the accurate puncture that Maxillary region is neural, Er Qieke
For the diagnosis and treatment of other diseases, as accurate biopsy, the chemistry of Oral and facial tumor damage treatment, radion is inserted, shaping
Prosthesis etc., in a word, all iconographys confirm the site of puncture that can arrive can use this navigation system to carry out auxiliary
Help puncture.
