Fracture restoration fixer for long bones of limbs

Abstract

The invention discloses a fracture restoration fixer for long bones of limbs. The fracture restoration fixer comprises first metal rods, second metal rods, connecting rings, a kirschner wire, a special kirschner wire and a pressed screw; the first metal rod is adjacent to the second metal rod and is connected with the second metal rod through the connecting ring to form a three-dimensional framework, two ends of two kirschner wires are arranged in through hole parts of two first metal rods which are arranged relative to each other, the middle part of each kirschner wire respectively penetrates through cortical bone on two sections of fractured bones, the special kirschner wire is arranged in a hollow part of the pressed screw, the pressed screw is installed in a screw hole on each of the first metal rod and the second metal rod, the pressed screw is locked onto the metal rods, and a tip of the special kirschner wire is compressed onto the fractured bone. The fracture restoration fixer has the beneficial effects that: when the fracture restoration fixer is used for carrying out the minimally invasive surgery, only local anesthesia is needed, simplicity in operation can be realized, and convenience in operation in primary hospitals; and surgical injury is small, the soft tissue surrounding the fractured bone is not damaged, the bone is unlikely to shift after the fractured bone is straightened, and the early functional training can be taken by the patient.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a fracture reduction fixer for long dry bones of limbs. Background technique [0002] The choice of treatment method for extremity fractures has been controversial for many years, and there are probably two views at present. One is surgical treatment: it is believed that the reconstruction of the anatomical structure is the basis for future functional recovery. Only through surgery can a good reduction of the broken bone and early functional exercise be achieved. Nice feature restoration. The other is conservative treatment: it is believed that most patients with limb fractures can achieve functional restoration through conservative treatment such as manipulation and traction, and do not need to undergo tissue re-injury and internal fixation removal during the operation. [0003] The inventor has been engaged in orthopedic clinical practice for a long time, and the fixation o...

Problems solved by technology

However, during the treatment process, the conservative treatment of fractures mainly relies on manipulative reduction, external fixation with small splints or plaster external fixation. Although the damage is small, there are disadvantages of difficult reduction and weak fixation. If the external fixation is too tight during fracture fixation, the blood circulation of the affected limb will be affected. If it is too loose, the fracture will be redisplaced due to local muscle contraction; in order to prevent the displacement of the fracture end, the upper and lower joints of the broken bone must be fixed, so that the joints of the broken bone cannot perform early functional exercises, and later it will easily cause joint stiffness and muscle tension. Atrophy

Surgical incision and internal fixation, although the fixation is firm and the anatomy is aligned, extensive soft tissue stripping is required during the operation. The destruction of the soft tissue hinge will affect the blood supply of the fracture end, affect the growth of callus, prolong the fracture healing time, and fracture healing. Afterwards, the internal fixation removal operation is required, which increases the pain of the patient, and the surgical scar will affect the appearance
