Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to an ilium osteotomy and shaping guide plate kit for repairing defects of lower jaw corners and lifting parts.
Background
The mandible is positioned at the protruding part of the jaw face and plays a decisive role in the appearance and the function of the face of a human body. The defects of the mandible can be caused by tumor, trauma and infection, thereby causing serious functional and appearance disorder of the patient and greatly influencing the life quality of the patient. Since the first use of the ilium flap by Taylor for the repair and reconstruction of jaw defects in the last seventies, the vascularized ilium muscle skin flap has gradually become one of the dominant bone flaps for the repair and reconstruction of mandibular defects.
The traditional iliac flap preparation method is that an operator manually measures the defect range of the mandible in the operation according to experience, so as to cut and shape the bone; with the maturity of digital surgical techniques and 3D printing techniques in recent years, various iliac osteotomy guides have gradually appeared, which can assist in osteotomy and shaping of iliac flaps to some extent, and improve operation efficiency and precision compared to conventional methods.
The traditional preparation method of the ilium flap does not adopt a guide plate for assisting in osteotomy, which has high requirements on the experience and operation level of a surgeon, and the overall repair process highly depends on the personal level and experience of the surgeon and often needs long operation time; meanwhile, the accuracy and precision of repair are difficult to ensure in the lack of auxiliary operation, so that the face shape of a patient is often difficult to effectively reconstruct; more importantly, because the external shape of the ilium is different from that of the mandible, the traditional preparation method usually requires a lot of time for trimming the bone block contour, which is generally performed after the tissue valve is broken, thereby greatly increasing the ischemia time of the tissue valve.
The currently adopted iliac osteotomy guide plate can determine the osteotomy range, but can only guide the osteotomy of iliac crest, and cannot guide the osteotomy of anterior inferior iliac crest and other parts. When the ilium section prepared by the existing bone cutting guide plate is in place, the spatial position of the ilium section also lacks uniqueness, and each bone block and the residual ends of the mandible at two sides can slide mutually, so that the repairing error is caused, thereby causing various surgical complications such as the change of the face appearance and the like, and finally influencing the treatment effect. Meanwhile, the traditional bone cutting guide plate has the risk of damaging the vascular pedicle and the blood vessel in a bone cutting process due to the large size.
The existing ilium trimming guide plate is large in size, difficult to place, careless to operate and even easy to damage a blood vessel pedicle and a blood vessel puncture branch; the retention height of the trimming guide plate depends on anatomical structures such as teeth, and once dentition in the mouth of a patient is seriously damaged or corresponding anatomical structures are lost, the in-position uniqueness cannot be obtained; the more important defect is that the existing trimming guide plate still needs to be placed and used after the tissue valve breaks the pedicle, and the problem that the tissue valve is still not solved due to too long ischemia time; in addition, the existing trimming guide plate is extremely complicated in operation, and the operation time is greatly prolonged.
The present application proposes the following effective solutions to the problems in the related art.
