External skeletal fixation orthopedic frame

Abstract

The invention relates to an external skeletal fixation orthopedic frame, which comprises a near end ring, a far end ring, a connecting sheet and a taylor rod, wherein each of the near end ring and the far end ring is a metal ring with round holes; the round holes are uniformly distributed in the ring; the connecting sheet is fastened on the round holes of the near end ring or the far end ring; the taylor rod comprises a stud, a sleeve and a universal joint; the stud is telescopically arranged in the sleeve through screw threads; the elongation or the shortening of a connecting rod is realized through helical transmission of the stud; the lower end of the sleeve is hinged to the connecting sheet or the far end ring through the universal joint; the upper end of the stud is hinged to the connecting sheet or the near end ring through the universal joint. The external skeletal fixation orthopedic frame is improved and designed on the Taylor frame technology; the external skeletal fixation orthopedic frame which can improve the surgical safety and the flexibility and provides a larger skeletal orthopedic space is provided.

Description

technical field [0001] The invention relates to the field of medical devices, and more specifically relates to an orthopedic external fixation orthopedic bracket for orthopedic surgery and fracture reduction. Background technique [0002] Dr. Taylor improved the Ilizarov external fixation system by connecting six telescopic extension rods obliquely to the proximal and distal rings, and they can rotate freely at the connection points. As long as the length of one of the connecting rods is adjusted, a ring will Change position relative to another ring. The Taylor frame is a six-degree-of-freedom parallel mechanism of the standard Stewart platform, which has the characteristics of high rigidity, strong bearing capacity, no accumulation of position errors, high stability, and high precision. However, in actual use, the selection of Taylor frame frame components becomes critical. Doctors should consider factors such as the patient's physique, degree of limb deformity, and postop...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the disadvantages of the existing Taylor frame, such as hidden dangers in operation safety, poor flexibility, and limited bone orthopedic space, the present invention improves the design of the Taylor frame technology and provides a method that can improve surgical safety and flexibility. Provides an orthopedic bracket for external fixation with greater bone orthopedic space
