Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a bone screw implantation device. Background Technology

[0002] This research on bone screw implantation devices primarily addresses the latest advancements and challenges in internal fixation techniques, materials science, and biomechanics within orthopedic surgery. With the increase in traffic and industrial accidents, the number of fracture patients has risen significantly, leading to a growing demand for efficient and reliable fracture fixation methods. The need for rapid recovery and minimal surgical trauma among athletes and other high-intensity individuals has driven the development of minimally invasive surgical techniques. Furthermore, with the global aging population, fractures caused by osteoporosis are becoming increasingly serious, necessitating fixation solutions more suitable for the elderly. Novel bone screws and implantation devices require rigorous clinical trials to verify their safety and effectiveness, including long-term follow-up studies of implanted patients to assess the long-term stability and biodegradation process of the bone screws. Bone screw implantation devices encompass multiple aspects, from clinical needs to technological innovation. As technology advances and medical demands continue to rise, the design and application of bone screw implantation devices are constantly evolving and optimizing to improve surgical outcomes, reduce patient suffering, and promote rapid recovery.

[0003] With the continuous development of medical technology, the requirements for internal fixation devices in orthopedic surgery are becoming increasingly stringent. Traditional bone screw implantation devices have certain limitations during operation, such as insufficient fixation stability and the need to improve biocompatibility. Furthermore, most existing orthopedic surgical fixation devices are complex to operate, which greatly increases the difficulty and time of surgery. Therefore, we propose a bone screw implantation device to solve this problem. Utility Model Content
