Description
Technical Field
The invention relates to the technical field of minimally invasive finger avulsion fracture, in particular to a minimally invasive finger avulsion fracture reduction internal fixation device.
Background
For the tear-off fracture of the phalanx, the prior closest similar technologies are mainly a kirschner wire internal fixation technology and a U-shaped finger dragging external fixation technology. The Kirschner wire is a commonly used surgical plant in orthopedics and is a stainless steel wire with a sharp end and a blunt end and a smooth flat surface. The gauge is typically fixed at about 23 cm in length and between 0.88-4 cm in diameter. The bone fracture fixation device is used for fixing short fractures or avulsion fractures and other fractures with low stress, and is also commonly used for fixing temporary fracture blocks in orthopedic operations. U-shaped finger drags are another external fixation mode of conservative treatment local braking commonly used in orthopedics. The splint has a spongy lining contacting the skin, and a bendable rectangular aluminum plate serving as an outer lining to serve as a splint, and two adhesive tapes are arranged on the near side and the far side of the splint to fix fingers. The specific specification and model are different. It is used for fixing distal phalanx avulsion fracture, comminuted fracture, interphalangeal joint dislocation, etc.
The kirschner wire fixing technology is an operation treatment technology. 1. The closed puncture needle has poor fracture alignment, so the open reduction internal fixation is often performed. The blood circulation around the fracture is injured and torn off by the incision operation, and the fracture block is easily changed into dead bone. 2. Since the k-wire requires a power system to drill in, there is thermal damage to the surrounding soft tissue and bone. 3. When the kirschner wire is used for fixation, the experience of an operator is greatly depended, the error rate is high, the operation time is long, and repeated wearing causes great influence on tearing off a fracture block. 4. Although belonging to internal fixation, the internal fixation also belongs to a relatively stable fixation technology because the broken end is not pressurized. 5. Because the Kirschner wire has no thread, the internal fixation is easy to loosen; if the torn fracture block is small, when the broken block is fixed by only one kirschner wire, the broken block is unstable in rotation, and the resetting and losing are easy to happen. 6. And because the tail end of the nail tube is left outside the body, the patient is required to carry out nail path nursing, and therefore, the risk of nail path infection and the like also exists.
The U-shaped finger drags and belongs to an external fixing device. 1. The external fixing device has lower stability strength and belongs to a relatively stable fixing technology. Fracture usually realizes the second-stage healing, easily causes the abnormal healing, influences the limb function of suffering from. 2. When closed injury is combined with tendon injury, avulsion fracture is easy to form fracture unconnected or hammer fingers. The patient is therefore not only restricted in mobility but may also be at risk for secondary surgery. 3. The patients hold the fingers for one month, which is easy to cause the complications of the finger joint stiffness and the like, and the prognosis is poor.
