Description
Technical Field
The utility model relates to a medical treatment anatomical model makes technical field, concretely relates to percutaneous spine minimal access surgery fixes a position puncture training model based on ultrasonic scanning location.
Background
Prolapse of intervertebral disc is a common and frequently encountered clinical disease. According to statistics, up to 80% of people suffer from neck and shoulder pain or lumbocrural pain caused by intervertebral disc protrusion in life, and the life quality and the labor capacity are seriously influenced. While most patients can be relieved by rest, physical therapy, medication or other non-surgical means, about 10-20% of patients need to take various types of surgical intervention into account.
At present, minimally invasive spinal surgery has been applied to discectomy, laminectomy decompression, foraminotomy, intervertebral fusion, and the like.
Percutaneous spinal endoscopic surgery is a minimally invasive and most effective surgical procedure developed in recent years for treating herniated intervertebral discs. The operation only uses a tiny wound of about 0.8cm, accurately and effectively relieves the oppression of nucleus pulposus of intervertebral disc to nerve roots under the direct vision of an endoscope, rapidly eliminates pain, has small wound, keeps the normal physiological activity of the spine, and does not need fusion and fixation.
The percutaneous endoscopic surgery facility has strong mobility, and the display system is universal with other surgical endoscopic platforms, so the required economic investment is not high, and the percutaneous endoscopic surgery facility is suitable for being developed in primary hospitals in districts and counties. However, the technical threshold of percutaneous spinal endoscopy is high, the control is not easy, the requirement on accurate positioning and puncture of an operation target point is extremely high, the control can be gradually controlled by learning of many cases, and the learning process is extremely difficult in the current medical environment.
At present, puncture positioning of a clinical percutaneous spinal endoscopic surgery mainly depends on X-ray fluoroscopy of a C-arm machine in the operation, a doctor performs experimental puncture and determines a puncture position through fluoroscopy again according to a plain film and puncture positioning experience, the above processes are usually repeated for many times, the consumed time is long, and a patient is also required to endure trauma caused by multiple punctures; on the other hand, the radiation damage caused by this is not negligible. The intraoperative CT can realize relatively quick and accurate puncture positioning, but the high selling price of the CT makes a general hospital hard to bear, and the radiation exposure risk of the CT is often higher than that of intraoperative X-ray fluoroscopy. The existing spine operation navigation equipment in clinic often needs to cut the skin to set a fixed mark point on the surface bone of the spinous process or the iliac crest, the process is invasive, the wound required by the positioning is often more obvious than that of endoscopic operation, and the spine operation navigation equipment has a non-invasive principle and is only suitable for positioning of the traditional spine open operation.
Therefore, the mature, reliable, simple and convenient-to-operate percutaneous spine minimally invasive surgery positioning technology without ionizing radiation exposure risk is developed, the technical threshold of spine minimally invasive surgery can be lowered, medical radiation exposure is reduced, and the positioning technology has good clinical practice value and great significance. Ultrasound has many advantages of being radiationless, portable, and capable of being used in operation, but is a short plate of ultrasound in bone imaging, and the obtained image information is less because the ultrasound cannot penetrate through bone structures. At present, there are many breakthrough researches on image fusion processing, wavelength adjustment, electromagnetic positioning, etc. by scientific research institutions, examples of the methods for navigation in spinal surgery are also available, and the application of ultrasound to preoperative positioning and intraoperative navigation in minimally invasive spine surgery is a future trend. The unique water proof ultrasonic scanning design of this puncture model for the ultrasonic wave can see through specific silica gel material, and water proof scanning presents the medical image of the backbone model of below, also can further carry out real-time three-dimensional reconstruction, presents the bony anatomy structure of puncture point below directly perceivedly.
