Description

technical field

[0001] The invention relates to the technical field of orthopedic surgical instruments, in particular to an adjustable quick alignment positioning device. Background technique

[0002] As the world's aging population increases, more and more people are suffering from knee lesions. Knee osteoarthritis is the joint disease with the highest incidence rate in osteoarthritis, and total shoulder arthroplasty (TSA) is an effective means to treat end-stage degenerative osteoarthritis. Whether abroad or at home, TSA is being carried out more and more. Orthopedic surgery is an important part of surgery. Through surgical replacement of artificial joints, patients who suffer from pain or even paralysis due to osteoarthritis, soft tissue wear, etc. can regain their mobility.

[0003] In traditional orthopedic joint replacement, the position and direction of osteotomy are determined by the operator's subjective experience or simple devices positioned on both sides of the...
