Description

Backbone tumour total spine resection surgery drag hook

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a backbone tumour holochiotomy drag hook.

Background

Spinal tumors fall into two categories, primary and metastatic. Primary tumors originate from the bony component of the vertebrae and are relatively rare and can be classified as benign and malignant tumors. The secondary tumor is derived from spinal metastasis of other internal organ tumors in vivo and is malignant tumor. Common benign tumors are: giant cell tumors, osteoid tumors, osteoblastic tumors, hemangiomas, and the like; common malignant tumors are: chordoma, osteosarcoma, chondrosarcoma, and the like. Spinal tumors are characterized by local pain or nerve compression due to different reasons (primary or metastatic), and partial or complete removal of vertebral body tumors can relieve nerve compression, reduce recurrence and prolong survival time. After the spine tumor is removed, the spine stability can be maintained by bone grafting or internal fixation as appropriate. In the spine tumor resection operation, a guide clamp is often needed to clamp the wire saw cutter and then send the wire saw cutter to a cutting site so as to realize the tumor resection.

However, the deep anatomical position of the spine and the large blood vessels or the important organs of the pleuroperitoneal cavity on the ventral side of the vertebral body are difficult problems in the field of spinal surgery. The therapeutic principle of oncology is that the whole tumor tissue is cut without tumor, and a layer of normal tissue is wrapped outside the tumor tissue, but the important organs around the spine limit the surgical cutting range, and the recurrence rate of the spinal tumor patient can be obviously reduced by adopting the whole-spine resection, but at the same time, the complication incidence rate and the patient mortality rate of the surgery are also obviously higher than those of other surgery methods, and part of the reasons are related to the damage of the adjacent important blood vessels and organs around the spine, so the retractor for protecting the important blood vessels and organs on the ventral side is commonly used in the whole-spine resection, the retractor can be placed from the back side to the ventral side to separate the vertebral body from the organs such as the aorta, the inferior vena cava and the like on the ventral side in the surgery, so as to perform the spine resection operation, however, the angles of the retractor in the prior art are all fixed and can not be adjusted according to needs, in the surgery process for different people, the requirements on the operator are high, and the effect of separating the vertebral body from organs such as the abdominal aorta, the inferior vena cava and the like cannot be achieved.
