Description

TECHNICAL FIELD

[0001] The present application relates to the field of clinical medicine, and in particular to a 3D-printed multi-site jaw cyst endoscope-assisted surgical curettage teaching model. BACKGROUND

[0002] Jaw cyst is a cystic lesion that occurs in the jaw, characterized by painless slow growth, and can persistently destroy the surrounding bone; cyst curettage is the most common method for treating jaw cysts; however, some cysts will recur after curettage, and the important reason is that the cyst wall is thin, the surgical field is poor, and cyst wall residues are easily found in the tooth root and dead angle positions; in order to improve the effect of cyst curettage and reduce the recurrence rate of cysts, part of the jaw bone is usually removed to better expose the surgical field, which will inevitably cause a large amount of bone loss, affecting the stability of the teeth and the effect of bone healing;

[0003] An endoscope is a high-tech device that integrates traditional optics, precision machinery, and electronic information technologies, and has the advantages of high brightness, large viewing angle, and flexible angle, etc. Under the assistance of an endoscope, cyst curettage can improve the operating field and reduce cyst wall residues, and is a new emerging cyst surgery method. Under the assistance of an endoscope, jaw cyst curettage can observe whether there are cyst wall residues through multiple angles of the endoscope, improve the field of view, and reduce the recurrence rate of cysts. At the same time, the use of an endoscope can better observe the internal morphology of the cyst and the bone wall, reduce the amount of jaw bone removed, and make the jaw bone healing more ideal. In addition, this method can effectively identify and separate important anatomical structures (such as the inferior alveolar nerve and maxillary sinus mucosa), reduce intraoperative damage and postoperative complications.

[0004] However, in current clinical practice, using an endoscope to assist in jaw cyst curettage is still a high threshold surgical procedure that requires the operator to have a full understanding of the anatomy of the jaw, cyst curettage instruments, endoscopes, and other operating experience. Young surgeons need a long learning and training period to independently perform such surgery. The existing teaching methods mainly remain at the stage of teachers' verbal instruction and demonstration, and young doctors cannot get efficient training in the early stage, and need a lot of time to observe and imitate the relevant operations of experienced doctors, which is low in learning efficiency.

[0005] The existing technology can display the morphology of the jaw cyst from multiple angles through CT three-dimensional reconstruction, strengthen the impression of the doctor, and also has the method of printing a mandibular model and manually making a defect area, and using a water bag to simulate a jaw cyst to actually display the morphology of the jaw cyst. However, this does not effectively combine with the actual characteristics of the clinical cases. There is currently no systematic training model and method for jaw curettage technology, especially for training under the assistance of an endoscope.

[0006] Therefore, a 3D-printed multi-site jaw cyst endoscope-assisted surgical curettage teaching model is needed. SUMMARY
