Embodiment 1

[0017] The mandibular ultra-long curve osteotomy nerve locator includes a tooth sleeve 1, a main rod 2, a slider 3, a positioning block 4, and a secondary rod 5. The main rod 2 is marked with a scale from top to bottom, and the slider 3 It is sleeved on the main rod 2, the tooth sleeve 1 and the slider 3 are connected by the connecting rod 6, and the slider 3 is fixed to the main rod 2 by the first screw 7 through the set screw hole. Specifically, the tooth sleeve 1 is two , Located on both sides of the main rod 2, more stable when fixed, respectively connected to the main rod 2 by two connecting rods 6 and two sliders 3, the connecting rod 6 is curved, and extends from the inside of the human oral cavity to the outside of the human oral cavity . The positioning block 4 is also sleeved on the main rod 2, and is fixed to the main rod 2 by a second screw 8 through the provided screw holes, and the auxiliary rod 5 is set across the positioning block 4.

Embodiment 2

[0020] On the basis of Example 1, specifically, the tooth sleeve 1 includes two clips 1-1, the clips 1-1 are arc-shaped pieces bent inward on both sides, which are convenient to fit the teeth and clamp the teeth. The upper end of the clip 1-1 is provided with a connecting part 1-2, and a third screw 9 is arranged to pass through the connecting part 1-2 and the connecting rod 6 to connect the connecting part 1-2 with the connecting rod 6. It is convenient to adjust the angle of the clip 1-1 to adapt to the shape of the tooth.

Embodiment 3

[0022] On the basis of Embodiment 2, specifically, the connecting portion 1-2 and the clip 1-1 are connected in a stepped manner, and the distance between the two connecting portions 1-2 is less than that of the two clips The distance between slices 1-1. It is convenient to fit the clip 1-1 more closely to the teeth.

[0023] The best embodiment:

[0024] The mandibular ultra-long curve osteotomy nerve locator includes a tooth sleeve 1, a main rod 2, a slider 3, a positioning block 4, and a secondary rod 5. The main rod 2 is marked with a scale from top to bottom, and the slider 3 It is sleeved on the main rod 2, the tooth sleeve 1 and the slider 3 are connected by the connecting rod 6, and the slider 3 is fixed to the main rod 2 by the first screw 7 through the set screw hole. Specifically, the tooth sleeve 1 is two , Located on both sides of the main rod 2, more stable when fixed, respectively connected to the main rod 2 by two connecting rods 6 and two sliders 3, the connectin...

Abstract

The invention relates to medical instruments and specifically relates to a nerve locator for mandible super-long curve osteotomy. The nerve locator comprises gear sleeves, a main rod, sliding blocks,a locating block and an auxiliary rod, wherein the main rod is marked with scales from top to bottom, the sliding blocks sleeve the main rod, the gear sleeves are connected with the sliding blocks through connecting rods, and the sliding blocks are fixed with the main rod through first screws by virtue of formed screw holes; specifically, the two gear sleeves are respectively arranged on two sidesof the main rod, are more steady during fixation and are respectively connected with the main rod through the two connecting rods and the two sliding blocks, and the connecting rods in an oral cavityof a human body are of a bending shape and bend and extend outwards; and the locating block sleeves the main rod and is fixed with the main rod through a second screw by virtue of a formed screw hole, and the auxiliary rod is arranged on the locating block in a transverse penetrating manner. The nerve locator can be used for marking the position of a mandibular nerve tube during the mandible super-long curve osteotomy, so that effective evading is realized.

Description

Technical field [0001] The invention relates to a medical appliance, in particular to a mandibular ultra-long curve osteotomy nerve positioner. Background technique [0002] In cranio-maxillofacial surgery professional medical facial contour surgery, such as mandibular super-long curve osteotomy, it refers to the removal of the facial bones from the mandibular angle to the mandibular chin, creating a naturally stunning small face, and obtaining good side effects not only eliminates hypertrophy Jaw angle can also shape the perfect chin. When performing a long-curve osteotomy operation, touch it with your hands or use a dental mirror to confirm whether the design is correct, an osteotomy saw should be used to perform full-thickness osteotomy according to the marks made in advance. When osteotomy, you should hold the handle of the swing saw steadily, vibrate the swing saw at a high speed, and perform osteotomy from back to front to prevent the osteotomy line from rising in the dire...
