Clamping device special for zygomatic fracture reduction operation

Abstract

The invention relates to a clamping device special for zygomatic fracture reduction operation, which comprises a fixing base and three clamping bodies. The fixing base is fixedly provided with a handle. The clamping bodies are hinged to the fixing base, and clamping ends of the clamping bodies are provided with clamping heads for realizing clamping action. Three clamping heads are correspondingly arranged on an inner side face of an external low edge of orbit, at the corner between an external edge of the orbit and the cheekbone, and at the corner between the cheekbone and a zygomatic crest support. An adjusting mechanism for clamping and loosening the clamping heads is arranged on the fixing base. Therefore, stable clamping force acts on three parts, namely an inner wall of the orbit, on the rear low part of the external edge of the orbit and at the zygomatic crest support, where the bone tissues are relatively firm, so that the maxillary process, the frontal process and the zygomatic process are integrally moved for reduction, and the problem that single prying or pulling is hard for the reduction of the cheekbone due to the complex shape of the cheekbone is solved. The clamping device special for the zygomatic fracture reduction operation can be used for large wound surface and minimally invasive zygomatic arch reduction, and has simple and reasonable structure and low cost.

Description

technical field [0001] The invention relates to a special device for surgery, in particular to a special clamping device for zygomatic fracture reduction surgery. Background technique [0002] Clinically, after the displacement of the zygomatic fracture, the moving direction and position of the fracture fragments are complex and diverse, resulting in the force of trauma often causing the zygomatic bone to shift inwards and backwards, resulting in the collapse and deformity of the zygomatic process of the face. Such fractures are often accompanied by Limited mouth opening, sunken eyeballs, orbital congestion and other symptoms. Because the zygomatic bone is located between the maxilla, frontal bone, and temporal bone, and adjacent to the above bones to form the anatomical shape of the orbit and zygomatic arch, the zygomatic bone is in the shape of three protrusions: zygomatic body, maxillary process, frontal process, The zygomatic process forms three spaces around the zygoma...

AI Technical Summary

Problems solved by technology

But at the part where the zygomatic bone is adjacent to the maxillary bone, because the bone wall of the maxillary sinus is very thin, it is difficult for the sunken zygomatic bone to reset the maxillary process of the zygomatic bone with general force; at the part where the zygomatic bone is adjacent to the frontal bone, because There is an eyeball in the orbital wall, and the inner side of the orbital wall is smooth, so there is no place to apply prying force to reset the displaced zygomatic frontal process; as for the displacement of the zygomatic process, the general lifting method can only reset the zygomatic arch The shape of the cheekbone cannot be completely reset as a whole, which often brings great difficulties to the final fixation of the cheekbone due to inaccurate reduction.

In addition, using a retractor or a crowbar, multiple incisions must be made on the skin tissue around the cheekbones, which in turn causes unnecessary secondary damage to the facial appearance of the injured
