Description

Novel mandibular integration osteotomy guide plate
Technical field
The utility model relates to biomedical engineering technology field, specifically a kind of novel mandibular integration osteotomy Guide plate.
Background technique
Jaw defect caused by tumour, wound, inflammation etc. can face to patient and function generate extremely apparent shadow It rings, to bring physiology and psychological serious blow to patient, influences patient's social activities and life quality.As facial area Maximum and unique mobilizable bone tissue, recovery of the reconstruction of mandibular for functions such as the facial appearance of patient and chewing voices It is of great significance, can greatly improve the psychological condition and quality of life of patient.
In recent years, with the rapid development of iconography, microsurgery and Computer Aided Surgery, the digitlization of mandibular Reconstruction technique is widely applied, and has pushed the mandibular defect reparation weight using the progress such as vascularization free fibula, ilium Build the development of technology.Guide plate is designed and digitized by virtual operation, and clinician can make for different situations rapid and convenient Complicated personalization guide plate enormously simplifies surgical procedure relative to the modus operandi based on Conventional wisdom, shortens hand The art time.
But because jawbone anatomical structure is special, surface irregularity, there are the important anatomy structures such as tooth, nerve channel, individual differences It is different big, and ilium, fibula used in reconstruction etc. is also the bone tissue of irregular form, so no matter how to cut in art Bone is finally both needed to make osteotomy surface, contact surface and angle certain adjustment.There are certain saw blades to cause during osteotomy Bone tissue loss, during adjustment, multiple bone sections adjustment accumulation error will with defect increase and amplify, finally lead It causes that condyle is prominent, there are biggish deviations for angle of mandible etc. mark point and design scheme, and easily leads to tissue damage.In addition soft in art Additional interference is organized, causes effect and Design of the bone after the fitting reconstruction of position also to there is certain deviation, in lower jaw When the second repair of bone defect is rebuild, since the offset of bone block is larger, the problem is more significant.
How to optimize 3D printing personalization guide plate, reduces the error because grinding, modifying the accumulation such as bone face, in place, it is ensured that repair Mandibular Morphology after multiple reconstruction is consistent with position with Design, still lacks a kind of suitable design scheme.
Utility model content
The utility model devises a kind of mandibular integration osteotomy guide plate of novel Anatomical orientation, which can be effective It reduces bone caused by electric saw to be lost, reduces osteotomy section deviation caused by guide plate deviates in place, reduce in art because adjustment bone block, bone connect The in place of transplanting bone block is not interfered in the shortening or extension of osteotomy section caused by contacting surface and angle, does not influence the in place of fixed titanium plate, The relative tertiary location of broken ends of fractured bone bone block can accurately be retained.By the integration guide plate, 3D printing personalization guide plate can be reduced in jaw Repeatedly shift and consume the deviation of appearance in bone remoulding art, it is more acurrate, reconstruction rapidly is carried out to mandibular defect, it reduces Postoperative complications shorten operating time, shorten length of stay.
A kind of novel mandibular integration osteotomy guide plate, it is characterised in that:
Including fragment sticking part, bridging portion, dissection fixed point portion, location hole and saw lanes;
The fragment sticking part includes the preceding leaflet sticking part and rear leaflet sticking part of structure in the form of sheets, for wrapping and pasting The bone lateral surface and lower edge for closing Mandibular disease area two sides bone section, play the role of maintenance and support;
The preceding leaflet sticking part is connected with rear leaflet sticking part by bridging portion, bridging portion in the form of sheets, rod-shaped or arc;
Preceding leaflet sticking part is equipped with dissection fixed point portion;The shape for dissecting fixed point portion is the circle being adapted with mental foramen form Protrusion, diseased region is ipsilateral or the mental foramen recess as anatomical landmarks of opposite side for being buckled in, and it is quick to play osteotomy guide plate Effect in place;
Be provided on the preceding leaflet sticking part and rear leaflet sticking part and perform the operation the matched location hole of titanium nail dimension,
A saw lanes are respectively provided on the preceding leaflet sticking part and rear leaflet sticking part, two saw lanes are located at mandibular Diseased region two sides are surrounded diseased region with this.
Preferably, the preceding leaflet sticking part and rear leaflet sticking part are respectively equipped with 1-2 location hole, location hole is interior The annular hollow column structure of diameter 2mm, outer diameter 4-8mm, height are 3-4mm lower than the length that operation titanium is followed closely, to guarantee titanium nail Maintenance.
Preferably, the saw lanes are the fine crack road structure of width 0.8mm, it is located at Mandibular disease area lateral border 1cm, Lower edge lower edge on guide plate is 2mm distance thereon, is bevel structure on the inside of saw lanes.
Preferably, the preceding leaflet sticking part and rear leaflet sticking part with a thickness of 2-5mm.
Preferably, the bridging portion and preceding leaflet sticking part, rear leaflet sticking part contact point with a thickness of 4-8mm, In order to avoid forming weak and stress raiser.
It is parallel to each other preferably, two saw lanes are at least a part of.
Compared with prior art compared with, the beneficial effects of the utility model are:
The guide plate can substantially reduce osteotomy section deviation caused by 1. jawbone affected area osteotomy guide plate deviates in place;The area ②Gong Gu The shortening or extension of osteotomy section caused by domain osteotomy guide plate and bone face laminating degree;3. deviation caused by the loss of saw lanes.Pass through The novel all-in-one osteotomy guide plate, can effectively reduce 3D printing personalization guide plate in reconstruction of jaw art because grind, modify bone face, The deviation in place for waiting repeatedly transfer and consume accumulation appearance, it is ensured that Mandibular Morphology and position and Design after reconstruction Unanimously, operation precision is improved, operating time is shortened.
