Abstract
Description
Technical Field
[0001] The invention relates to the field of medical instruments, and in particular to a puncture locator for spinal surgery. Background Art
[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items used directly or indirectly on the human body, including the required computer software. Medical devices include medical equipment and medical consumables.
[0003] Spinal surgical puncture is a medical procedure used to diagnose and treat spinal diseases. Depending on the condition, the doctor will choose different puncture methods, including percutaneous puncture and open puncture. Percutaneous puncture is a minimally invasive technique that punctures the skin to the lesion site for examination or treatment. During the percutaneous puncture process, the doctor will use imaging technology, such as CT, MRI or X-ray, to locate the lesion site and determine the best puncture path. The advantages of percutaneous puncture are small trauma and fast recovery, and it is suitable for the diagnosis and treatment of most spinal diseases. Open puncture is a more complicated operation that requires cutting the skin and muscle tissue to directly reach the lesion site for examination or treatment. During the open puncture process, the doctor needs to use tools such as scalpels and traction devices to choose different incisions and surgical approaches according to the different lesion sites. The advantage of open puncture is that the condition of the lesion site can be directly observed, which is suitable for serious spinal diseases that require thorough treatment.
[0004] For example, a spinal surgical puncture locator with publication number CN117281594A moves the puncture positioning device on the surface of the hospital bed so that the puncture needle is aligned with the top of the patient's puncture position, and then controls the puncture needle to move downward to puncture into the patient's body. However, the actual operation process is more difficult. The puncture needle is on the top of the patient's body, and the operator observes the puncture needle descending to the patient's puncture position with the naked eye. The visual method is relatively inaccurate, and the puncture needle may be inaccurate when it moves downward. At the same time, iodine tincture needs to be manually wiped before puncture, which is cumbersome. In addition, the area of wiping iodine tincture is large, and there is a situation where wiping iodine tincture affects the accurate observation of the puncture position.
