Problems solved by technology

The navigation template is mainly positioned and fixed by the bridge of the nose and the root of the ear, so the mask area is larger, the printing time is longer, and the cost is higher
In addition, due to interfering factors such as hair, the ears are not easy to fit; a large mask fits on the face will give people an uncomfortable feeling; for people with thick subcutaneous fat, facial expressions will also cause the mask to move, thus affecting positioning
The structure of the formwork is not compact, and it is prone to deformation during transportation and disinfection, which affects its accuracy

Embodiment 1

[0030] The preparation method of the maxillofacial puncture navigation device based on 3D printing technology, the steps include:

[0031] A. Perform CT thin-layer scan on the patient's interest area (including teeth) to obtain scan data;

[0032] B. Import the scanning data into the medical modeling software, establish a three-dimensional digital model of the maxillofacial bone in the area of ​​interest, and mark the target position. The three-dimensional digital model includes the patient's dental model;

[0033] D. According to the three-dimensional digital model, use the software to establish the simulated optimal puncture needle path and puncture depth to reach the target position. The optimal puncture needle path needs to avoid important blood vessels and nerves;

[0034] E. Import the patient's three-dimensional digital model and the simulated optimal puncture needle path data into the software to generate the puncture navigation device model according to claim 1, so th...

Embodiment 2

[0037] Such as figure 1 As shown, the maxillofacial puncture navigation device based on 3D printing technology is a printed integrated device, including a fixing device and a guiding device. The fixing device includes a fixing rod 1 and a brace 2, and the brace is a brace for the upper teeth , can trap 4-6 upper teeth, the guide device includes a guide rod 3 and a puncture column 4, a through hole is established in the puncture column, which is a puncture hole 5, the guide of the fixed rod of the fixation device and the guide device The rod connection constitutes the connection means.

Embodiment 3

[0039] Such as figure 2 As shown, this maxillofacial puncture navigation device based on 3D printing technology is a printed integrated device, including a fixing device and two guiding devices. The fixing device includes a fixing rod 1 and a brace 2, and the brace is the Braces can cover 4-6 upper teeth. The guide device includes guide rods 3,6 and puncture columns 4,7. Through holes are established in the puncture columns, which are puncture holes 5,8. The fixed rod is connected with the guide rod of the guide device to form a connection device, and the puncture holes 5 and 8 of the two puncture columns 4 and 7 are coaxial through holes, which are positioned on the same position of the maxillofacial region.

Abstract

The invention discloses a maxillofacial-region puncture navigation device based on the three-dimensional print technology.The maxillofacial-region puncture navigation device is an integrated device formed in a three-dimensional print mode, comprises a tooth socket and at least one puncture column, and further comprises a connecting device for connecting the tooth socket and the puncture column.A through hole is formed in the puncture column, and is a puncture hole.The invention further discloses a preparing method of the maxillofacial-region puncture navigation device.The maxillofacial-region puncture navigation device based on the three-dimensional print technology is fixed to upper teeth through the tooth socket and is not prone to displacement, and positioning is more accurate.Meanwhile, a plurality of puncture holes can be formed in the same navigation device to carry out multi-target-point puncture or same-target-point different-path puncture, and the operation success rate is increased.In addition, two guide rods can be arranged on a fixing rod of the same connecting device, the puncture holes of the two puncture columns are located in a same straight line accordingly, and the accuracy of a puncture needle channel is further increased.

Description

technical field [0001] The invention relates to a maxillofacial puncture navigation device based on 3D printing technology and a preparation method thereof, belonging to the field of medical image processing and application. Background technique [0002] Cranial neuralgia (such as trigeminal neuralgia, glossopharyngeal neuralgia, sphenopalatine neuralgia, etc.) is a typical neuropathic pain. The pain is severe during the attack, which seriously affects the daily life of the patient, and some even commit suicide because of it. [0003] In general, patients with cranial neuralgia can be controlled to a certain extent through drug treatment, but when the disease progresses or cannot be treated with drugs for various reasons, minimally invasive treatment is the common choice of doctors and patients. Radiofrequency thermocoagulation has become the most commonly used minimally invasive treatment method because of its good short-term and long-term curative effects. It is to insert ...
