Adjustable rapid alignment positioning device

Abstract

The invention discloses an adjustable rapid alignment positioning device. The adjustable rapid alignment positioning device comprises a handheld mechanism, an upper positioning mechanism and a lower positioning mechanism, wherein an opening and closing limiting mechanism is arranged between the rear ends of an upper handle and a lower handle of the handheld mechanism, and a connecting plate is arranged at the front end of the upper handle of the handheld mechanism; the upper positioning mechanism comprises an upper positioning block and a connecting column; a milling surface is provided with scales, a connecting port allowing the connecting plate to be inserted is arranged on the upper positioning block, a connector is slidably arranged on the connecting column in a sleeving manner, a first alignment rod and a second alignment rod are detachably fixed at two ends of the fixing part of the connector respectively, and the lower positioning mechanism is slidably arranged on the connecting column at the lower end of the connector in a sleeving manner; and the lower positioning mechanism comprises a lower positioning block and a scale reading block fixed to the outer surface of the lower positioning block, the scale reading block and the lower positioning block are fixed in a sliding mode, and a sliding limiting mechanism is arranged between the scale reading block and the lower positioning block. The device is simple in structure and reasonable in design, the positioning efficiency and the positioning precision can be improved, and the biological force line can be recovered more accurately.

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...

AI Technical Summary

Problems solved by technology

Placement by experience is too affected by subjective factors, and it is easy to deviate from the correct position

Since the simple device is placed on both sides separately, the accumulation of position errors on both sides will cause a large overall position deviation

In addition, due to the operation on both sides of the joint, it takes a long time and is interfered by soft tissues, making the operation difficult
