Description

Technical Field

[0001] The present application relates to the technical field of osteotomy navigation, and in particular to a multi-layer osteotomy navigation device for dentistry. Background Art

[0002] Stomatology is one of the medical disciplines. The main oral diseases include oral and maxillofacial dermoids, submandibular space infection, maxillofacial lymphangioma, odontoid malformation, maxillary sinus malignant tumor, jaw ameloblastoma, chronic ethmoid sinusitis, mandibular retraction, tetracycline teeth, leukoplakia of the tongue, etc. Through technology, many periodontal diseases can be completely cured. The development of tissue bioengineering technology such as guided tissue regeneration technology, genetic technology, and implant dentures has brought exciting hope for the regeneration of diseased teeth. When performing osteotomy in the oral cavity, in order to increase the surgical operation space, an opener is usually used to open the patient's mouth, and then the doctor holds an endoscope to explore the inside of the mouth, and observes the recovery of the wound after the osteotomy through the photos taken.

[0003] Through searching, Chinese patent announcement number CN113598873B discloses the field of oral surgery technology, specifically relates to an oral surgery multi-layer osteotomy navigation device, including a stretching module and a tube delivery module, the stretching module is movably connected with two opening plates, the tube delivery module includes an L-shaped rod, the bottom end of the L-shaped rod is fixedly connected to the stretching module, one end of the top of the L-shaped rod is fixedly connected to a delivery box, the top surface of the delivery box is provided with a delivery groove, and the inner side of the delivery box is rotatably connected to two delivery blocks. In the present invention, the delivery box is rotatably connected with a delivery block, the endoscope tube can be transported by the delivery block, and the round block can make the endoscope tube bend to one side, the angle of the round block can be adjusted by a power mechanism, thereby adjusting the bending direction of the endoscope tube, and there is no need to manually hold the endoscope tube, and subsequent inspections can be performed with the same tube delivery length and direction, thereby keeping the angle and range of photography unchanged, which is conducive to the observation of postoperative wound recovery.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0005] Although the above patent does not need to manually hold the endoscope tube, thereby maintaining the angle and range of photographing unchanged, the navigation device in the above patent can only open the patient's mouth laterally during the process of opening the patient's mouth, and it is difficult to fix the patient's mouth firmly. When the patient opens his mouth for a long time, it will cause muscle fatigue, and the patient will unconsciously cause a certain degree of closure, which will easily lead to a certain degree of deviation in the position and angle of the photo taken this time and the photo taken before, which will affect the comparison effect between the two sets of photos, and further affect the observation of the patient's postoperative wound recovery.

The shortening of the electric push rod 1 3 can drive the supporting frame 4 to descend, and lower the opening block 1 76 and the opening block 2 89 into the patient's mouth. At this time, rotate the control handle 75. The rotation of the control handle 75 can drive the main gear 73 to rotate. When the main gear 73 rotates, it can drive the two racks 72 to move in opposite directions, and then drive the two connecting rods 1 77 and the opening block 1 76 to move in opposite directions, so as to open the patient's mouth in the lateral direction. When the main gear 73 rotates, it can At the same time, it drives the two sub-gears 74 to rotate. When the two sub-gears 74 rotate, they can drive the two adjusting screws 82 to rotate. The rotation of the adjusting screws 82 can drive the two movable screw blocks 83 to move in opposite directions, and then drive the two connecting rods 84 and the opening block 89 to move in opposite directions, so as to open the patient's upper jaw and lower jaw, and then fix the patient's mouth from the front-to-back direction. This device can fix the patient's mouth from the front-to-back direction and the lateral direction at the same time, and can achieve a good fixing effect. After multiple photos, the position and angle of the front and back photos will not deviate, which is convenient for consistent observation of the recovery of the patient's postoperative wound.
