Orthopedic surgical traction device

Abstract

The invention discloses an orthopedic surgical traction device. The orthopedic surgical traction device is characterized by comprising two mutually independent leg fixing components which are appliedto a human left leg and a right leg respectively. Two adjacent fixing hoops of each crus traction assembly and the corresponding thigh traction assembly are connected through two second traction screws on two sides of the corresponding thigh and crus traction assembles, two ends of each second traction screw penetrate a corresponding rotating connection ring, and second locking nuts sleeve the second traction screws on two sides of each rotating connection ring. A large end of a rod portion of each rotating connection ring is in rotation fit with a mounting blind hole in the outer wall of a corresponding fixing semi-ring, and a small end of the rod portion of each rotating connection ring penetrates a positioning hole of a limiting cover which is fixed to the outer wall of the corresponding fixing semi-ring. The orthopedic surgical traction device is directly fixed to two sides of a fracture part to realize traction, completely different from existing head and sole traction means and is short in traction distance, great in traction effect and less prone to causing extra fracture injuries.

Description

technical field [0001] The invention belongs to the field of orthopedics, in particular to a traction device for orthopedics operations. Background technique [0002] At present, traction is usually used clinically for lower limb surgery patients. The purpose of traction is to relieve pain, reduce swelling, reset, and avoid secondary damage to fracture stump blood vessels and nerves caused by fracture recurrence. Present traction device mainly contains two kinds of traction modes, and the first kind is to fix and traction the head, such as CN2008201268794. The second is to fix and pull the soles of the feet, such as CN2012204816227. And, the prior art all has a bed board, and the traction and fixing parts are all connected to the bed board. For example, CN2008201268794 adopts components such as weights for traction, and its traction structure is connected to the bed board. In addition, the prior art also provides complex height and level adjustment structures for positioni...

AI Technical Summary

Problems solved by technology

[0004] 1. The above two fixation and traction methods fix and tract the head and soles of the feet, away from the fracture site, not only the traction effect is not good, the pain relief, swelling and reset effects are not obvious, but also the head or soles of the feet are easily fractured by traction , resulting in additional fractures, and keeping the traction position is not conducive to rapid recovery

[0005] 2. All the fixing and traction components are connected to the bed board, which increases the complexity of the structure and increases the cost

[0006] 3. It is equipped with a complex height and level adjustment structure, which not only greatly increases the cost, but also the patient has to stay in a fixed position on the bed for a long time during traction, and cannot move at all. Not only is the customer's comfort poor, but it is also very unfavorable for fast recover
