Light guide type medical angle measurement-controller

Abstract

The invention discloses a light guide type medical angle measurement-controller. The light guide type medical angle measurement-controller comprises a measurement-guide structure used for measuring and guiding the operation direction in a surgery or a puncture operation and the like, and a supporting structure used for performing lifting and rotating adjustment on the measurement-guide structure;the measurement-guide structure comprises a fixed structure, and a first sleeve and a second sleeve movably connected to the fixed structure; a first supporting rod and a second supporting rod extendfrom ball heads in the first sleeve and the second sleeve, and the top of the first supporting rod and the top of the second supporting rod are provided with a first dial plate and a second dial platerespectively; a light source is arranged in the middle lower part of each of the first sleeve and the second sleeve; and operation tools, such as a puncture needle and the like are attached to the surfaces of the first sleeve and the second sleeve, or are parallel to the light source light beams. The light guide type medical angle measurement-controller not only can measure the angle of operationin the operation, but also can guide the operation direction after the operation angle is preset, can be compatible with operation tools such as acetabulum grinding rod or puncture needles of different manufacturers in the market, and is convenient to popularize and popularize..

Description

technical field [0001] The present invention relates to the technical field of medical instruments, in particular to a light guide type medical angle measurement-controller, which is suitable for doctors to measure and guide the direction or angle of their operation during operations such as surgery or puncture. Background technique [0002] When doctors perform puncture or surgery on the sick human body, they often need to operate at a certain angle or direction to improve the accuracy of treatment and try to avoid damage to important structures such as large blood vessels, nerves, and internal organs of the human body. When taking a biopsy, it is required to avoid important structures such as the abdominal aorta. When performing operations such as percutaneous vertebroplasty or percutaneous radiofrequency ablation of intervertebral discs, the puncture needle is required to avoid nerve roots. Appropriate operating angle or direction can allow the operating tools to reach th...

Problems solved by technology

In some cases, an appropriate operating angle can also improve the long-term curative effect of the operation. For example, total hip replacement refers to implanting artificial joint prosthesis into the body through surgery to replace the damaged femoral head and acetabulum. Replace the damaged hip joint to eliminate pain and restore normal joint activity and function. It has been widely used in rheumatoid arthritis, osteoarthritis, avascular necrosis of the femoral head, femoral neck fracture nonunion, congenital The cases of hip dysplasia and ankylosing spondylitis have achieved relatively satisfactory clinical results, but at the same time there are still the following deficiencies: Because the surgeon often evaluates the abduction angle and anteversion angle of the acetabular cup with the naked eye during the operation , is prone to relatively large errors, resulting in improper installation of the acetabular prosthesis, resulting in poor postoperative efficacy in some patients; in order to avoid excessive errors, some methods such as X-ray perspective are used to evaluate the acetabular socket during surgery The placement angle of the cup, but the X-ray fluoroscopy operation is more troublesome, and the X-ray may also cause radiation damage to the human body

At present, there are artificial joint replacements assisted by navigation or robots, which have achieved good accuracy in use, but the operation is time-consuming, which significantly prolongs the operation time, increases intraoperative blood loss, and increases anesthesia complications and infections. and other risks, and the navigation (or robot) is expensive, often the navigation (or robot) developed by the same company can only be used for its own artificial joint products, and it is difficult to be well compatible with other companies' artificial joint products on the market , thus affecting its popularization and application; many existing studies aim at how to improve the accuracy of intraoperative acetabular prosthesis installation, and have designed some corresponding methods or appliances, but some methods are too cumbersome for intraoperative application, and some methods The error is still relatively large, and some instruments are not compatible with acetabular setbacks from different manufacturers, tools for placing acetabular cups, and puncture needles that are widely used on the market, thus affecting the promotion and popularization of these tools
