Abstract
The invention discloses a nerve protection guide plate for mandible osteotomy. The guide plate is integrally attached to the bone face of the mandible, an arc guide area is arranged on the edge of the guide plate, and the arc and the length of the guide area are matched with the arc and the length of the inferior alveolar nerve canal. The nerve protection guide plate for mandible osteotomy enables osteotomy to be carried out more easily, and is convenient for an operator to operate; osteotomy under guidance of the guide plate allows a mandible diseased region to be cut off precisely along the boundary, residual is avoided, and the risk of postoperative recurrence is effective reduced; osteotomy under guidance of the guide plate can effectively preserve the inferior alveolar neurovascular bundle, the serious complications, such as postoperative affected side chin lip skin numbness, tooth remaining on the affected side lower jaw, nerve loss of alveolar bone and the like, ischemia, inactivation and even necrosis, due to cutting or accidentally injure are avoided, and the postoperative life quality of patients is improved.
Description
Technical field
The present invention relates to a kind of medical aid, in particular a kind of Mandible Osteotomy neuroprotective guide plate.
Background technology
In the treatment of mandibular bone benign lesion, traditional operation often ignores the preservation of inferior alveolar nerve vascular bundle while excision mandibular bone focus, and existing osteotomy technology is that entirety amputates mandibular bone bone section of getting involved, and blocks and ligation inferior alveolar nerve vascular bundle simultaneously.This method certainly will cause nerve injury, and there is the danger of massive hemorrhage in art, and severe patient may threaten patient vitals; Secondly, in art, the determination of osteotomy scope often relies on the experience of simple imaging data and surgical doctor, if osteotomy is insufficient, then may cause Residue, increases the risk of postoperative recurrence; Again, after blocking inferior alveolar nerve vascular bundle, postoperative patient will occur that the permanent chin skin of lip of Ipsilateral is numb, and the severe complications such as denervation, ischemia, inactivation be even downright bad may appear in the remaining tooth of Ipsilateral lower jaw, alveolar bone etc. simultaneously, have a strong impact on patient's postoperative quality of life.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of Mandible Osteotomy neuroprotective guide plate, can be easy to use in art, realize precise positioning.
The present invention is achieved by the following technical solutions, and guide plate integral plaster of the present invention invests mandibular bone surface of bone, and the edge of guide plate is provided with the boot section with arc, and arc and the length of the arc of described boot section and length and inferior alveolar nerve pipe match.
As one of optimal way of the present invention, the thickness of described guide plate is 1.5 ~ 3mm.
Described boot section is bladed structure.For carrying out osteotomy by intra-oral approach.
Described boot section is shoulder structure.For carrying out osteotomy by the outer approach of mouth.
The width of described boot section is 2 ~ 3mm.Guide plate edge is inferior alveolar nerve cannon born surface projection position, just can accurately expose inferior alveolar nerve vascular bundle after osteotomy, is convenient to peel off in art and protects this important feature, occurs previously described multiple complications to avoid postoperative patient.
The present invention has the following advantages compared to existing technology: the present invention can make bone-culting operation more easily carry out, and is convenient to patient's operation; Instruct lower osteotomy along border precise ablation Mandibular disease, to avoid remaining through guide plate, effectively reduce the risk of postoperative recurrence; Instruct lower osteotomy effectively can preserve inferior alveolar nerve vascular bundle through guide plate, avoid due to excision or accidentally injure and severe complication, the raising patient postoperative quality of life such as denervation, ischemia, the inactivation such as postoperative Ipsilateral chin skin of lip numbness, the remaining tooth of Ipsilateral lower jaw, alveolar bone that cause be even downright bad.

Fig. 2 is the structural representation of embodiment 1;
Fig. 3 is the structural representation of embodiment 2.
Detailed description of the invention
Elaborate to embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
If Fig. 1 is ill mandibular bone schematic diagram, when dotted line L1 is approach outside mouth below inferior alveolar nerve pipe 1, be close to the osteotomy line of neurocele bone surface projection lower edge design; When dotted line L2 is intra-oral approach above inferior alveolar nerve pipe 1, be close to the osteotomy line of neurocele bone surface projection upper limb design.
Embodiment 1
As depicted in figs. 1 and 2, Fig. 2 is outer approach osteotomy guide plate 2 design diagram of mouth, guide plate 2 integral plaster of the present embodiment invests mandibular bone surface of bone, the edge of guide plate 2 is provided with three boot sections 21, the boot section 21 at two ends is used to indicate pathological changes and osteotomy scope, and the middle arc of boot section 21 and the arc of length and inferior alveolar nerve pipe 1 and length match.
The thickness of the present embodiment guide plate 2 is 2mm.The boot section 21 of the present embodiment is shoulder structure, and width is 2.5mm.Boot section 21 indicates the position of osteotomy line, and osteotomy and retain neural operation in the outer approach art of bootable mouth.
The present embodiment can be used in the treatment of the various mandibular bone benign lesion not involving inferior alveolar nerve vascular bundle, as bone fibres textural anomaly, ossifying fibroma, mandibular permanent first molar etc.Preoperative based on patient CT data, use three-dimensional reconstruction, accurately location lesion region and inferior alveolar nerve pipe position; Utilize CAD/CAM Technology design osteotomy and neural preservation guide plate, and made the individuation osteotomy guide plate being applicable to every patient by three-dimensional printing technology.Guide plate 2 entirety is transparent or milky, involves scope and inferior alveolar nerve pipe and is located and and guide osteotomy to operate, be beneficial to complete resection pathological changes in art by guide plate to the preoperative pathological changes determined, and dissects and preserve inferior alveolar nerve vascular bundle.
Embodiment 2
As shown in figures 1 and 3, Fig. 3 is intra-oral approach osteotomy guide plate 2 design diagram.The You Liangge boot section, edge 21 of guide plate 2, article one, boot section 21 is used to indicate pathological changes and osteotomy scope, arc and the length of the arc of another boot section 21 and length and inferior alveolar nerve pipe 1 match, and the thickness of guide plate 2 is about 2mm, fits tightly with outside mandibular bone; Boot section 21 is bladed structure, instruction osteotomy line position, and osteotomy and retain neural operation in bootable intra-oral approach art.Other embodiments are identical with embodiment 1.
