Problems solved by technology

However, after the installation of the existing calcaneus external fixation bracket, the operation space is narrow. After the calcaneus is reset, the doctor needs to maintain the reset posture with his hands to perform follow-up treatment. Not only is the operation space narrow, but also requires the cooperation of multiple people.

Abstract

The present invention discloses a calcaneus outer fixing support, and belongs to the technical field of medical equipment. The calcaneus outer fixing support comprises a first bone nail fixed to the distal end of the fibula, a second bone nail fixed to the corpora calcanei and a third bone nail fixed to the fifth metatarsal bone, wherein a connecting piece is arranged between every two of the first, second and third bone nails; each connecting piece comprises a lateral extension rod arranged on each bone nail and a connecting rod arranged between the lateral extension rods; the lateral extension rods are fixedly connected with the bone nails; each lateral extension rod has first motion of sliding on the corresponding connecting rod and second motion of rotating around the corresponding connecting rod; the third bone nail is sleeved with a fixing device; and the fixing device is used for controlling the position and angle of the third bone nail. The surgery operation space is large, andthe bone nails can be fixed by the support after calcaneus restoration, so that both hands of a doctor are freed to perform subsequent surgery operation; and the calcaneus outer fixing support is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a calcaneal external fixation bracket. Background technique [0002] Bone external fixator can be used in the treatment of common fractures in clinical practice, and can also be used to correct some bone deformities. It is an important device in orthopedics. Any external fixator includes three basic parts: fixation pin, fixation pin holder and connecting rod. When used for fracture treatment, the operation method is usually to insert the fixation pin at the position and angle of the needle after the fracture is reduced. Then install the clamps, connecting rods, etc. However, after the installation of the existing calcaneal external fixation bracket, the operation space is narrow. After the calcaneus is reset, the doctor needs to maintain the reset posture with his hands to perform follow-up treatment. Not only is the operation space narrow, but also requires the cooper...
