A non-intermittent automatic operation spinal minimally invasive robotic hand based on flank guidance

Abstract

The invention relates to a non-intermittent automatic operation type spinal minimally invasive robotic hand based on flank guidance, which comprises a base plate, an interface is arranged on the base plate, and is characterized in that: an endoscope lens, an aspirator and a Main lift mechanism. At the same time, the main lifting mechanism is connected with a bite-cutting device through the steering mechanism, the bite-cutting device is connected with the connecting seat, and the bite-cutting device includes a bite-cutting forceps. In addition, a guide tube is arranged in the bite-cutting forceps, a cam mechanism is connected to the bite-and-cutting forceps, the cam mechanism is connected with a bite motor through a connecting shaft, and a return spring is arranged between the connecting seat and the bite-cutting forceps. Furthermore, a cutting straw is arranged in the guide tube. Able to participate in the implementation of spinal surgery, especially to help medical staff perform various spinal surgeries such as spinal fractures, spinal tumors, scoliosis, intervertebral disc herniation, spinal stenosis, spondylolisthesis, etc. The overall application range is wide, the operation is simple, safe and reliable.

Description

technical field [0001] The invention relates to a minimally invasive robotic hand, in particular to a non-intermittent automatic operation spinal minimally invasive robotic hand based on flank guidance. Background technique [0002] At present, tens of thousands of patients with spinal diseases around the world undergo various nerve decompression operations every year, such as traditional laminectomy, nucleus pulposus removal, and minimally invasive intervertebral fusion under endoscopy. Because the surgery is done near nerves, damage to the nerves can cause paralysis. Therefore, safe and effective nerve decompression is of great significance in the field of spinal surgery. [0003] The surgical instruments used for nerve decompression mainly include the following types: 1. The lamina rongeur is manually operated, and the method of "cutting the knife once, biting off once, and removing chips once" is adopted, and nerve compression can only be completed after multiple operat...

AI Technical Summary

Problems solved by technology

Each operation requires the identification of resected tissue and the adjustment of the posture and position of the rongeur, so there is a risk every time, not only time-consuming and laborious, but also a little carelessness may cause an accident

2. The electric grinding drill can reduce the intensity of the doctor's work, but due to the high speed, there are many risk factors, such as high temperature generated by friction between the grinding head and the cutting surface, easy to entangle the soft tissue in the spinal canal, and manual grinding is difficult to accurately control the grinding head The depth of entry, instability and easy loss of hands, etc., may cause nerve damage, so it is usually used to thin the lamina bone tissue and cannot be directly used for its full-thickness resection and decompression

3. Ultrasonic knife, the efficiency is low, and heat will be generated during the bone cutting process, usually used for carving and grinding of small pieces of bone tissue

The robot has obvious disadvantages. It cannot completely grind through the lamina bone. It still needs manual operations such as lamina rongeurs to remove the remaining lamina that is most closely in contact with the nerve tissue, which cannot effectively reduce the surgical risk.
