Cheekbone positioning fixing apparatus

Abstract

The invention provides a cheekbone positioning fixing apparatus, which comprises two forceps bodies consisting of forceps handles and forceps heads. The two forceps bodies are connected in a crossed manner via a hinge pin, a finger ring hole and a fixing clamping tooth are arranged at the rear end of each forceps handle, the fixing clamping teeth on the two forceps handles match mutually, claw hooks are arranged at the front ends of the two forceps heads, the plane with the claw hooks is perpendicular to a plane with the forceps handles, a plane with mouths of the claw hooks is parallel to the plane with the forceps handles, a conical groove is arranged on the inner side surface of each claw hook along the length direction of the claw hook, and the grooves on the inner side surfaces of the two claw hooks correspond to each other. The cheekbone positioning fixing apparatus is firm in clamping, cannot slip, guarantees surgery quality, shortens surgery time, can well realize that a bone stump of a cheekbone after a part of the cheekbone is cut off is fixed stably and reliable in the facial contouring industry, can utilize absorbent threads or nylon threads to replace steel wires for fixation or miniature titanium steel plate screws for fixation, and eliminates the drawback that metal foreign bodies are remained in the face of a patient forever.

Description

Technical field: [0001] The invention relates to the technical field of medical devices, in particular to the technical field of facial contour shaping and beauty, in particular to a zygomatic bone positioning fixator. Background technique: [0002] At present, facial contour plastic surgery, especially the closed reduction and fixation of the bone stump after zygomatic lowering osteotomy, adopts the corresponding punching and positioning on the bone stump after zygomatic osteotomy. There is no special surgical forceps when the stump is closed and reset, and the corresponding hole can only be pulled together and then ligated with large curved forceps. The existing surgical instruments have no reset fixation and lead wire functions, so when doing this kind of small-field surgery, only Use steel wires to fix the two holes corresponding to the broken ends of the bones together or fix them with micro-titanium plate screws. Due to the use of steel wires or micro-titanium plate sc...

Problems solved by technology

[0002] At present, facial contour plastic surgery, especially the closed reduction and fixation of the bone stump after zygomatic lowering osteotomy, adopts the corresponding punching and positioning on the bone stump after zygomatic osteotomy. There is no special surgical forceps when the stump is closed and reset, and the corresponding hole can only be pulled together and then ligated with large curved forceps. The existing surgical instruments have no reset fixation and lead wire functions, so when doing this kind of small-field surgery, only Use steel wires to fix the two holes corresponding to the broken ends of the bones together or fix them with micro-titanium plate screws. Due to the use of steel wires or micro-titanium plate screws for fixation, metal foreign bodies will permanently remain on the face, which will affect the results of future medical examinations, such as CT examinations. , nuclear magnetic resonance examination, etc.; if a second operation is used to remove the metal foreign body, it will increase the pain and financial burden of the recipient

Moreover, this kind of surgical forceps cannot be suitable for operation requirements because of its unreasonable structure, and it is easy to slip off when clamping, and it is difficult to fix in a narrow visual field. The broken end is displaced again, the broken end is poorly aligned, and the reduction of the broken bone after osteotomy is inaccurate, and fixation failure often occurs, and it is often necessary to repeat several times. The operation time is very long, and repeated reduction and fixation may cause complications such as neurovascular injury, which brings great trauma to the recipient, increases the difficulty of the operation, and also increases the physical and mental burden of the surgeon.
