Description

Motor Removable Two-Way Adjustable Taylor Mount

technical field

The utility model relates to the field of orthopaedic correction and rehabilitation, in particular to a two-way adjustable Taylor frame with a detachable motor.

Background technique

In the surgical treatment of skeleton, the fixation device is indispensable. The traditional fixation method generally adopts the internal fixation of the steel plate, and now there is also a less traumatic external fixation treatment method—the Taylor skeleton external fixation. Dr. Taylor attached six retractable extension rods to the proximal and distal rings at an inclination, and were free to rotate at the connection point. As long as the length of one of the extension rods was adjusted, one ring would change position relative to the other. . Using computer program software, the length of the extension rod can be calculated relative to the deformity parameters, and the Taylor space frame can be pre-constructed to imitate any deformity to treat and correct various simple or complex fractures and deformities.

At present, the spiral Taylor frame is used in the field of orthopedic rehabilitation. During clinical operations, the doctor first installs a fixing ring on the patient. After the positions of the distal ring and the proximal ring are determined, they are connected with a Taylor rod. The length of the Taylor rod can be changed by adjusting the distance between the stud and the sleeve, and the telescopic length of the six Taylor rods can be gradually adjusted to gradually correct the relative posture between the proximal ring and the distal ring, so as to realize the reduction, correction and fixation of the bone. However, in clinical practice, it is found that the efficiency of the spiral-adjusted Taylor rod is not high enough, especially when the fracture dislocation is relatively large, and the installation is too slow during surgery. At the same time, the accuracy of the spiral adjustment method is not high enough. During the operation, in order to ensure the accuracy, the electric drive method can be used for adjustment. However, electric-driven telescopic devices such as electric push rods, linear motors, etc., cannot control the distance during installation well, and may require multiple fine-tuning during installation, and the effect is not good.
