Embodiment Construction

[0049] This embodiment is an anatomical locking plate type external fixator of the whole tibia, which is made of titanium alloy.

[0050] The external fixator is a special-shaped steel plate with enlarged at both ends and narrowed in the middle, and the middle of the external fixator has torsion, which is consistent with the skeleton of the distal end of the tibia, the inner side of the proximal end of the human tibia, and the anterior inner side of the tibial shaft. Both ends of the external fixator are enlarged fan-shaped, one end is the distal end 8 of the external fixator, which is used to connect the distal end of the tibia 12 of the human body; the other end is the proximal end 7 of the external fixator, which is used to connect the proximal tibia of the human body. 15.

[0051] One side surface of the external fixator is a concave arc surface; the concave arc surface is adapted to the surface structures of the medial malleolus of the distal end of the tibia and the medi...

Abstract

The invention discloses a tibia whole-segment anatomical locking plate type external fixing frame which is an integral steel plate. The outer fixing frame is similar to the inner side of the tibia far end and the inner side of the tibia plateau in anatomical form, the middle section of the plate-type structure is consistent with the front inner side of the tibia shaft in shape, and multi-angle adjustable locking nail holes are formed in the two ends. The device accords with medical AO and BO theories, can be used by domestic adults with the height of 160-175cm, can comprehensively consider various types of fractures of tibia, can replace internal fixation, avoids secondary operation of taking out internal fixation, and prevents complications of internal fixation of tibia fractures. And the problem troubled by people who are not suitable for internal fixation of patients can also be solved. Meanwhile, the defects that a traditional single-arm outer frame is tedious, heavy, poor in stability and incapable of effectively fixing fractures at the far end and the near end of the tibia are overcome, time and labor are saved during operation, social benefits are economical and practical, pain of a patient lying for a long time after an operation is reduced, and the rehabilitation time of the patient is shortened.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a bionic locking type plate-type external fixator for tibial fractures. Background technique [0002] Open tibial fractures are a common type of fracture in clinical practice, and internal fixation plates are prone to complications such as wound closure, bone exposure, infection, and nonunion. If traditional external fixators (single-arm external fixators, Semi-ring type, combined type, Ilizarov external fixator), it will cause difficulty in surgical operation for those with skin and soft tissue defects that need to be repaired. Moreover, once internal fixation fails, it will bring a great burden to the patient's economy and body and mind. Internal fixation should not be used for special patients with tibial fractures complicated by diabetic foot, osteoporosis, leg edema caused by lack of renal function, and poor blood circulation in the legs caused by other reasons. Therefor...
