Problems solved by technology

For example, the universally adjustable fracture external fixer designed by the inventor can adjust the position and direction of the fixing nail hole arbitrarily, so that the distance and direction of the drilled hole in the operation are no longer strictly limited by the fixer, thereby reducing the difficulty of operation , but the translation and rotation of the device must be operated separately, and the accuracy is low
Other three-dimensional external fixators, such as the Irizanov frame and the Basini frame, etc., also cannot simultaneously satisfy all movements such as translation and rotation required for fracture reduction.

Embodiment Construction

[0016] Embodiment shown in accompanying drawing, overall structure of the present invention comprises upper and lower two fixed chassis 1,3 and 6 support rods 2 that two ends are respectively hinged on two fixed chassis 1,3, and every support rod 2 is by the outside The sleeve tube 4 and the slide bar 12 inserted in the sleeve tube 4 are formed, so that its effective length can be telescopically adjusted. There is a clamping head 9 that can clamp the slide bar 12 at one end of the socket 4 and the slide bar 12, and the end of the sleeve 4 at the rear of the clamping head 9 has an external thread, and a lock nut 11 is mounted on it. , the clamping head 9 has a certain taper, and there are several gaps 10 in the longitudinal direction. When the lock nut 11 is rotated and moved backward, the inner side of the clamping head 9 can be pressed inward to clamp and fix the slide bar 12. The other end of the casing 4 also has an external thread, and the ball hinge 5 is installed on the ...

Abstract

The invention relates to a reset fixing frame for orthopedics, belonging to the technical field of medical apparatus and instruments for clinical bone-knitting. The reset fixing frame for orthopedics is provided with two fixed base plates and six support rods with adjustable effective lengths, wherein both ends of the support rod are respectively articulated on the two fixed base plates; each support rod is composed of a sleeve and a sliding rod inserted in the sleeve; and the sleeve and the sliding rod are respectively arranged on the fixed base plates through spherical hinges. The support rods are extended and adjusted by utilizing the sliding rods, active movement of the support rods is changed into passive movement driven by the base plates, and six actions such as compression prolongation, left-right angulation, fore-and-aft angulation, left-right translation, for-and-aft translation and rotation can be carried out according to the alignment requirement at bone stump, so that the reset fixing frame for orthopedics is accurate for positioning, simple and convenient to operate and wide in range of application.

Description

technical field [0001] The invention relates to the technical field of medical instruments for clinical osteosynthesis, in particular to an external fixator for fracture correction and reduction. Background technique [0002] In recent years, orthopedic fixation devices have developed rapidly, and various fracture orthopedic reduction devices have appeared clinically. For example, the universally adjustable fracture external fixer designed by the inventor can adjust the position and direction of the fixing nail hole arbitrarily, so that the distance and direction of the drilled hole in the operation are no longer strictly limited by the fixer, thereby reducing the difficulty of operation , but the translation and rotation of the device must be operated separately, and the accuracy is low. Other three-dimensional external fixators, such as the Irizanov frame and the Basini frame, etc., also cannot simultaneously satisfy all movements such as translation and rotation required...
