Problems solved by technology

Combined with literature reports and clinical treatment experience, there are the following disadvantages: Open reduction and internal fixation is used, and a second operation is usually required to remove the internal fixation
Clinically, external fixation with distal femoral, proximal tibial or distal plates has been used, but these internal locking plates for external fixation do not match the body surface, are too thin, have weak mechanical strength after external fixation, and have single functions and other shortcomings

Embodiment Construction

[0033] Examples, see figure 1 As shown, a low-profile locking tibial external fixator of the present invention includes a distal anteromedial fixation plate 1 , a proximal anteromedial fixation plate 2 , two connecting rods 3 and an adjustment member 4 .

[0034] see figure 2 and image 3 As shown, the distal anteromedial fixation plate 1 includes a distal fixation part 11, a first locking part and a first adjustment part 15. The distal fixation part 11 is in the shape of a long plate on which a plurality of universal The locking hole 12, the first locking part includes two connecting rod sliding holes 13 and two jackscrew screw holes 14 communicating with the connecting rod sliding holes 13 respectively, and the first adjusting part 15 is a stud. see Figure 4 and Figure 5 As shown, the proximal anteromedial fixation plate 2 includes a proximal fixation portion 21, a second locking portion and a second adjustment portion 24. The proximal fixation portion 21 is in the sh...

Abstract

The invention discloses a low-incisura locking type external tibia fixing frame which comprises a first fixing plate, a second fixing plate and an adjusting structure. A plurality of universal lock holes are respectively formed in the first fixing plate and the second fixing plate so that external nailing is facilitated; the adjusting structure and an anti-deflection structure are arranged betweenthe first fixing plate and the second fixing plate; the anti-deflection structure is used for guiding anti-deflection when the relative distance between the first fixing plate and the second fixing plate is adjusted, the adjusting structure enables the relative distance between the first fixing plate and the second fixing plate to be adjustable, the fracture end has certain extending and pressurizing functions, and bone healing can be promoted. The design of multiple rows of holes close to joints on the fixing plate can form multi-plane fixation.

Description

technical field [0001] The invention relates to a low-profile locking tibial external fixator. Background technique [0002] Tibial fracture is a common trauma in orthopedics, and internal fixation with plate or external fixator is also the most common surgical method in clinic. Combined with literature reports and clinical treatment experience, there are the following disadvantages: Open reduction and internal fixation is used, and a second operation is often required to remove the internal fixation. For some complex and open fractures, external fixators are often used for fixation. Traditional external fixators are mostly "nail-rod-clip" composite structures, with high appearance notch, inconvenient to carry, and less reliable fixation, so they are mostly used as temporary fixation. Patients often need reoperation and switch to plate internal fixation, which increases the patient's pain and financial burden. In addition, when the traditional fixator is applied to the fra...
