Problems solved by technology

[0003] With the expansion of external limb fixation in clinical applications, there are more and more styles of external limb fixation frames. However, most of the existing external limb fixation frames are simple in style and single in function, which cannot meet the requirements of firmness, convenience and ease of fixation. Operability and other aspects of the demand, for this we have introduced a special orthopedic external limb fixation frame

Abstract

The invention discloses an external limb fixing frame special for the orthopedic department. The external limb fixing frame comprises a first supporting plate and a second supporting plate which are symmetrically arranged at the two sides, the left end of the first supporting plate and the right end of the second supporting plate are connected through two lead screws, fixing legs are arranged at the lower side of the right end of the first supporting plate and the lower side of the left end of the second supporting plate respectively, two limb fixing rings are arranged at the upper side of theright end of the first supporting plate, and two limb fixing rings are arranged at the upper side of the left end of the second supporting plate. The external limb fixing frame is reasonable in layout and ingenious in structure, the whole device is fixed to a proper position through the fixing legs, then the limbs are supported through the two supporting plates, the four fixing rings are adoptedfor clamping the two ends of each required limb, then fixing nails penetrate through staggered bone at the two ends for after-position-correction fixation, and limiting screws are screwed up; meanwhile, a screw cover is adjusted to keep a proper distance between the two supporting plates, the requirement of limb fixation for the firmness and precision of the frame is met, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a special external limb fixation frame for orthopedics. Background technique [0002] External limb fixation refers to the use of external fixators to treat limb fractures. Over the years, its indications have mainly included patients with infected open fractures, skin loss that cannot be covered by phase I, or internal fixation that cannot achieve stable fixation. With the strengthening of the awareness of trauma, the indications for its clinical application are gradually expanding; external limb fixation can also prevent secondary damage caused by the broken end of the fracture stabbing blood vessels, nerves and other surrounding tissues, and reduce pain, which is convenient for rescue transportation and handling. [0003] With the expansion of external limb fixation in clinical applications, there are more and more styles of external limb fixation frames. However, most...
