Description

Technical Field

[0001] This utility model relates to the field of dental implants, and in particular to an mouth opening device specifically for implant surgery. Background Technology

[0002] Dental implantation, also known as implant prosthesis, is a method of restoration that involves surgically implanting an artificial implant into the alveolar bone of the mouth to replace the root of a missing natural tooth. After healing, the implant forms a stable osseointegration with the surrounding bone tissue, thereby supporting the crown of the tooth structure and achieving the goal of restoring tooth function and aesthetics.

[0003] During dental implant surgery, patients need to open their mouths quite wide. However, this can cause mouth pain if patients keep their mouths open for extended periods. Therefore, a special mouth opener is usually used to help patients open their mouths to a certain degree so that doctors can perform the implant surgery more effectively.

[0004] Most existing mouth openers are forceps type. When supporting the patient's mouth, their long handles will be placed horizontally on one side of the patient's mouth, which will not only make the patient uncomfortable, but also cause problems such as obstruction to the actual operation of subsequent implantation surgery.

[0005] Therefore, it is necessary to provide a new opening device specifically for implantation surgery to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides an opening device specifically for implantation surgery.

[0007] The surgical incision device for implantation surgery provided by this utility model includes a main support, a secondary support rotatably connected to one side of the main support, a baffle fixedly connected to one end of both the main support and the secondary support, a handle A rotatably connected to the end of the main support away from the baffle, and a handle B rotatably connected to the end of the secondary support away from the baffle. A mounting plate A is fixedly connected to the end of both handles A and B near the main support and the secondary support, respectively. Two limiting caps are fixedly connected to the mounting plate A near the main support and the secondary support on the same side. A mounting plate B is fixedly connected to the end of both the main support and the secondary support away from the baffle. A limiting rod is fixedly connected to the side of the mounting plate B near the mounting plate A on the same side. Both ends of the limiting rod are located inside the limiting caps on the same side and rotatably connected to them. A torsion spring is fixedly connected between the limiting rod and the inner wall of the limiting cap on the same side.

[0008] Preferably, the main support has a limiting hole, and the main support and the side opposite to the top of the handle A are provided with interconnected sliding grooves, and the inner walls of the sliding grooves are provided with limiting grooves on both sides.

[0009] Preferably, the main support and the handle A are slidably connected with a mounting frame, the mounting frame is fixedly connected with a sliding block on the side close to the sliding groove, the sliding block is slidably installed in the sliding groove, the two sides of the sliding block are fixedly connected with limiting strips, and the limiting strips are slidably connected with the limiting grooves on the same side, and the mounting frame is fixedly connected with a short gear rack on the end close to the limiting hole.

[0010] Preferably, the vice support is fixedly connected with an arc-shaped long gear rack on the side close to the main support, the long gear rack is located in the limiting hole, and the long gear rack is slidably connected with the inner wall of the limiting hole.

[0011] Preferably, the handle A is rotatably connected with a limiting plate, the handle B is fixedly connected with a limiting frame, the limiting plate is located in the limiting frame and is slidably connected with the limiting frame.

[0012] Preferably, the opposite sides of the two baffles are fixedly connected with illumination plates, and the sides of the baffles are provided with arc-shaped surfaces with grooves.

[0013] Compared with the related art, the mouth gag special for planting surgery has the following beneficial effects:

[0014] When supporting the mouth of the patient, the limiting plate is separated from the limiting frame, and the sliding block is completely moved into the sliding groove on the main support, at this time, the angle between the main support and the vice support is limited through the meshing of the short gear rack and the long gear rack, then the handle A and the handle B are rotated through the rebound force of the torsional spring, and the handle A and the handle B are rotated to be attached to the face of the patient, thereby reducing the problem that the main support and the vice support are too long and horizontally arranged on one side of the mouth of the patient, which easily affects the subsequent planting surgery.
