Embodiment 1

[0043] like Figure 1-10 As shown, the present invention provides a thickness-adjustable maxillary osteotomy locator, comprising a rod 1, the top of the rod 1 is fixedly connected with an adjustment support rod 2, and the top of the adjustment support rod 2 is fixedly connected with a lifting lip block 3. The front of the lifting lip block 3 is threadedly connected with a fixing bolt, the inner side of the lifting lip block 3 is rotatably connected with a positioning rod 4, the top of the positioning rod 4 is provided with a thickness adjustment plate 5, and the middle part of the rod 1 is provided with a rod-containing adjustment mechanism. 6. Both ends of the rod-containing 1 are provided with a water absorption mechanism 7, and the bottom of the rod-containing adjustment mechanism 6 is provided with a placement mechanism 8.

[0044] The thickness adjustment plate 5 includes a fixed plate 51 fixedly mounted on the top of the positioning rod 4 , the top of the fixed plate 51 is...

Embodiment 2

[0049] like Figure 1-10 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, a pull rope 54 is fixedly installed on the outer wall of the rotating rod 53, and the end of the pull rope 54 is far away from the rotating rod 53 and the top of the elastic plate 52 Fixed connection, the right side of the rotating rod 53 is provided with a rotating rod fixing mechanism 55, the inner cavity of the adjusting cylinder 61 is slidably connected with a sealing slide plate 65, and the end of the sealing slide plate 65 away from the center plate 62 is fixedly connected with the rod 1.

[0050] In this embodiment, the pull rope 54 is stored by the rotating rod 53 to cause the elastic plate 52 to deform, so as to realize the function of adjusting the supporting thickness of the fixed plate 51 . Inflation in the inner cavity of the adjusting cylinder 61 increases the air pressure in the inner cavity of the adjusting cylinder 61, and pushes th...

Embodiment 3

[0052] like Figure 1-10 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, a water absorbing plug 75 is movably connected to the inner cavity of the fixing ring 71, and a sponge ring 751 is movably connected to the right side of the water absorbing plug 75 , the right side of the sponge ring 751 is fixedly connected with a water guide mechanism 752, the water guide mechanism 752 includes a cone ring a1, the cone ring a1 is fixedly connected to the right side of the sponge ring 751, and the inner cavity of the cone ring a1 is fixedly connected with an arc guide plate a2, one end of the arc guide plate a2 away from the inner cavity of the cone ring a1 is fixedly connected with a water drop block a3, the left side of the water drop block a3 is fixedly connected with a collecting block a4, and the left side of the collecting block a4 is movably connected with the right side of the water suction plug block 75 .

Abstract

The invention discloses a maxillary osteotomy locator with adjustable thickness, which relates to the technical field of medical devices and includes a rod, the top of the rod is fixedly connected with an adjustment support rod, and the top of the adjustment support rod is fixedly connected with a Lifting lip block, the front of the lifting lip block is threadedly connected with a fixing bolt, the inner side of the lifting lip block is rotatably connected with a positioning rod, the top of the positioning rod is provided with a thickness adjustment plate, and the middle of the rod is provided with a Rod adjustment mechanism included. The invention adopts the combination of the elastic plate, the rotating rod, the pulling rope and the rotating rod fixing mechanism, and the fixing of the rotating rod is released through the rotating rod fixing mechanism. When bending occurs, the upper lip of the patient is raised, which is convenient for doctors to use instruments to cut the maxillary bone, solves the problem that the replacement of the fixed plate will affect the operation, shortens the operation time, and reduces the risk of the operation.

Description

technical field [0001] The invention relates to an osteotomy locator, relates to the technical field of medical devices, and in particular relates to a maxillary osteotomy locator with adjustable thickness. Background technique [0002] Dental and maxillofacial deformities are caused by the abnormal growth and development of the jaws, the volume, morphological structure, and the positional relationship between the upper and lower jaws and their relationship with other craniofacial bones are unbalanced. Systemic dysfunction, maxillary and jaw deformities are usually manifested as insufficient or excessive three-dimensional development, and maxillary occlusal plane deviation. When excising the maxilla, a locator should be used to cooperate with the doctor in excising the maxilla. The following problems exist for the prior art: [0003] 1. The existing osteotomy locator does not have the function of adjusting the bending thickness of the locating plate. During the operation, ...
