An intervertebral space disconnection system for massive total resection of thoracolumbar tumors

Abstract

The invention discloses an intervertebral space disconnection system for large total resection of thoracolumbar tumors. The intervertebral space disconnection system includes: a protective body and cuttings; the protective body includes a head end, a tail end and a body The end of the head end is a first concave structure that conforms to the protrusion of the intervertebral space; the protective body is an arc-shaped structure that matches the anatomical radian of the thoracolumbar spine; the cross-section of the body conforms to the protrusion of the intervertebral space. The second concave structure raised; the top of the protection body is provided with a wire groove along the axial direction of the protection body; the wire groove is used to accommodate the wire saw; on the two side walls of the wire groove along the protection body Two corresponding card slots are provided in the axial direction; the insertion strip matches the card slots; a recess communicating with the wire slot is provided above the head end; a hook is provided in the recess. The intervertebral space disconnection system claimed in the present invention is simple in operation, safe in use and good in effect.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a disc space disconnection system used for massive total resection of thoracolumbar tumors. Background technique [0002] Thoracic and lumbar tumor total vertebral mass resection is the only surgical procedure to treat thoracolumbar tumors through radical resection and save the patient's life, and it is also one of the most complicated operations in spine surgery. There are usually two methods of total vertebral mass resection: simple posterior approach and posterior + anterior approach. Posterior surgery alone is less traumatic than posterior + anterior surgery. However, since the posterior approach cannot directly view the anterior vascular structures (aorta, vena cava, iliac arteriovenous, segmental vessels, umbilical vein, and tumor feeding vessels), it is extremely difficult to dissect the anterior vertebral body and dissect the intervertebral space.

Problems solved by technology

[0009] 3. The way of stripping the front completely by the doctor's hands and separating blood vessels to stop bleeding is closely related to the doctor's personal experience and ability. It does not have visibility and repeatability at all, and cannot be popularized

Moreover, due to the large gap and loose tissue in front of the vertebral body, the method of packing and compressing cannot form effective pressure on the front blood vessels to stop bleeding. Therefore, the method of stripping and packing a large amount of gauze to stop bleeding will bring great risks to patients. Extremely bad

[0010] To sum up, in the prior art, there is no technical solution that can make the total vertebral resection of thoracolumbar tumors safe, efficient and low-risk
