Problems solved by technology

The existing bone external fixation bracket takes up a lot of space and is bulky, and it is inconvenient to carry after operation, and there is no physiological pressure device. The telescopic body (threaded rod) of the compression device moves the fracture segment at one end to the fracture end to generate bone compression. The displacement in millimeters can only be seen on the scale. After the ends are anastomosed, the value of the compressive stress at the end is unknown. , the physiological compressive stress cannot be reached, resulting in nonunion of fractures, and stress shielding of external fixation brackets often occurs, resulting in nonunion of fracture ends

Abstract

The invention provides a combined type multifunctinal physiological bone pressurization external fixation support, and belongs to the technical field of bone treatment equipment. The problems that a bone pressurizer conducts bone pressurization on the bone broken end blindly, a fracture is not healed frequently, the size of the bone pressurizer is large, the bone pressurizer is fixed outside the limb and is not convenient to carry, and inconvenience is brought to the post-operation life are solved. The combined type multifunctinal physiological bone pressurization external fixation support comprises a physiological bone pressurizer which is installed on a carbon fiber rod, a bone nail fixation clamp is further installed on the carbon fiber rod, the tail of a bone nail is installed on the fixation clamp, the physiological bone pressurizer is adjusted to drive the carbon fiber rod to move to the bone broken end, the carbon fiber rod drives the bone nail fixation clamp on the carbon fiber rod, the fixation clamp drives the bone nail, the bone nail drives the fracture section, and the physiological bone pressurization is completed. The combined type multifunctinal physiological bone pressurization external fixation support is small in size, light in weight, flexible and safe in physiological bone pressurization of the broken end and easy to operate, the cure rate is increased, and bone infection brought by open fracture treatment is avoided.

Description

technical field [0001] The invention relates to a bone external fixation bracket, in particular to a combined multifunctional physiological bone compression bone external fixation bracket, which is used for external fixation treatment of fractures in various parts of human limbs, and is especially suitable for multi-segment fracture nonunion bone compression The utility model relates to the treatment of multi-segment fracture nonunion by physiological bone pressure external fixation of broken end of bone defect and fracture nonunion, and belongs to the technical field of bone therapy equipment. Background technique [0002] Currently there is no combined multifunctional physiological bone compression bone external fixation bracket. The existing bone external fixation bracket takes up a lot of space and is bulky, and it is inconvenient to carry after operation, and there is no physiological pressure device. The other is an external fixation bracket with a bone presser, which ...
