Description

Multi-functional operating forceps of orthopedics

Technical Field

The invention relates to the technical field of medical instruments, in particular to an orthopedic multifunctional operating forceps.

Background

Osteology is also known as orthopedics. With the development and progress of science and technology, bone science has been greatly developed in diagnosis and treatment. With the change of times and society, the orthopedic injury spectrum also has obvious changes, for example, the diseases such as osteoarticular tuberculosis, osteomyelitis, poliomyelitis and the like are obviously reduced, the wounds caused by traffic accidents are obviously increased, the population is aged, the fracture and osteoscientific arthropathy caused by senile osteoporosis are increased, the influence of environmental factors is increased, bone tumors and rheumatoid arthritis are correspondingly increased, and the like. The change of the orthopedics wound spectrum requires that the key point of orthopedics research and the key point of prevention and treatment must be adapted to the change, which also determines the future development direction of orthopedics. The development of modern science not only needs to have fine disciplines, but also emphasizes the cooperation of multiple disciplines, and the development of orthopedics is the same, so that the future development of orthopedics requires more attention to the combination with the basic medicine, and also pays more attention to the full utilization of advanced scientific and technical achievements, for example, the further improvement of the function of the artificial joint must rely on the development of material science, and the new achievements of the material science are applied to the clinical orthopedics in time, so that the diagnosis and treatment level of the orthopedics can be improved to a new height.

Scissors, bone saws and forceps are also basic medical instruments commonly used in orthopedics, and are used for bone grafting and bone extraction in orthopedics, or for cutting and sawing bone warts, callus, osteoma, chondroma and the like. At present, scissors commonly used in clinic are composed of a cutting edge and a handle, when in bone grafting and bone taking operation in orthopaedics or cutting calcifications, poroma, verruca ossis and osteoma of human tissues, the scissors and a bone saw need to be repeatedly replaced, which is very inconvenient, wastes time and labor, increases the labor intensity of medical staff on one hand, prolongs the operation time on the other hand, and increases the pain of patients.
