Problems solved by technology

[0004] At present, some scholars can provide some spatial data of cranial and maxillofacial bone deformities before surgery through computer-aided design and digital simulation design, etc., but most of the data are indirect data, and doctors still need to rely on their personal experience during surgery To operate, it is difficult to solve the oral clinical problem

Embodiment 1

[0041] The inventor's craniofacial three-dimensional measuring device adopts stainless steel material, and the scale scale on each measuring ruler is (unit mm): the first horizontal measuring ruler 4 is respectively 50mm. to the scale marked on both sides from the midpoint, and the second horizontal measuring ruler 7 The scale marked from the midpoint to both sides is respectively 150mm, the scale of the third horizontal measuring ruler 9 from the midpoint to the two marks is also respectively 150mm, and the scale of the vertical measuring ruler 1 is 120mm.

[0042] Take the midpoint of the intersection of the 20 mm scale point at the upper end of the vertical measuring ruler 1 and the first horizontal measuring ruler 4 as the origin (0, 0, 0) of the three-dimensional coordinates, the direction to the right is positive, and the direction to the left is negative Value; the forward direction is a positive value, the backward direction is a negative value; the face-up direction is...

Embodiment 2

[0063] This embodiment is the treatment of a clinical patient (West Ward 2, Inpatient Department, West China Stomatological Hospital, Sichuan University, hospital number 52715). The patient's name, Xiong XX, male, 35 years old, was admitted to the hospital for more than one month due to a house collapse and injured his face. At that time, there was no coma, nausea, vomiting and other symptoms. He was treated in a local hospital. After his condition stabilized, he found that the occlusal relationship was not good and required further treatment, so he was admitted to West China Stomatological Hospital. After the outpatient examination, he was admitted to our ward with "old double maxillary fractures". Admission examination: T: 37.0°C, P: 80bpm, BP: 122 / 80mmHg, R: 19bpm. No obvious abnormalities were found in the whole body. Specialist examination: a linear scar was seen from the bottom of the eyelid to the left nose, a 7-8cm long scar was seen under the right lower lip, the low...

Abstract

The present invention relates to human craniofacial three-dimensional measuring equipment. Said measuring equipment has a three-dimensinal coordinate measuring scale which is formed from the components of vertical measuring rule, horizontal measuring rule and parallel measuring rule which is mutually perpendicular to the vertical measuring rule and horizontal measuring rule. Said invention also provides its three-dimensional measuring method and concrete steps.

Description

1. Technical field [0001] The invention relates to a treatment technique in trauma of oral craniofacial surgery, in particular to a human craniofacial three-dimensional measuring device and a measuring method thereof for measuring the structure and shape of normal or injured craniofacial soft and hard tissues. 2. Background technology [0002] With the continuous development of the transportation industry and the continuous improvement of people's living standards, various types of vehicles are increasing, resulting in more and more traffic accidents. The number of patients with maxillofacial fractures mainly caused by traffic accidents is increasing year by year. , Maxillofacial fractures often cause severe facial deformities in patients. So far, the treatment of such patients can only be based on the subjective reduction and fixation of the fracture site based on the doctor's clinical experience. The face often has lost the reference point of restoration, lacks objective ...
