Description
Technical Field
The invention relates to a thoracolumbar minimally invasive channel surgery retractor.
Background
For the common clinical lumbar and thoracic diseases such as lumbar intervertebral disc protrusion, lumbar spinal stenosis and thoracolumbar fracture, the protection of muscle tissues is very important with the continuous development of the spine minimally invasive technology. The approach of the muscle gap is a common minimally invasive surgery mode, but the approach of the muscle gap exposes the back of the vertebral plate, and usually needs to use a drag hook or a retractor for assistance, so that the muscle tissue on the inner side of the paravertebral surgery incision is dragged to the midline side, and the muscle tissue on the outer side is dragged to the outer side, so that the surgery operation area is fully exposed, and the muscle tissue on the chest, waist and back is protected. Various clinically applied draw hooks are available, but the following defects 1 that the root canal section of the nerve root draw hook is too small, the muscle tissue is not fully protected, the handle of the draw hook is too thin, the force of the draw hook is difficult to master by an assistant, the draw hook is easy to shift, a plurality of nerve root draw hooks are needed to be used together, and operators are often required to add more personnel in the operation; 2. the nail-shaped drag hook cannot completely protect muscular tissues due to the short front end, is not fully exposed, and is easy to rotate in the operation because the distance between the far end of the handle and the skin is too short, thereby causing the drag hook to move up and down. 3. The contact part of the retractor and the lumbar structure is cylindrical and is easy to slide up and down.
Meanwhile, the structure tip of the existing posterior minimally invasive surgery tool for the spinal column is too sharp and narrow, secondary injury is caused to a patient, postoperative recovery of the patient is affected, the depth of a drag hook of an obese patient is insufficient, soft tissues such as muscles cannot be fully blocked, the visual field is exposed insufficiently, and the problem of operation is affected.

Detailed Description
The invention is further described with reference to the following figures and detailed description.
As shown in fig. 1-4, a thoracolumbar minimally invasive channel surgical retractor comprises a round handle retractor and a right-angle retractor:
the round handle drag hook comprises a cylindrical handle, a connecting rod, a connecting plate body and a horizontal hook part which are sequentially connected, wherein the connecting rod is perpendicular to the connecting plate body, the horizontal hook part is positioned on the same side of the connecting rod, the connecting plate body is an isosceles trapezoid plate with a small upper end and a large lower end, the upper end of the connecting plate body is connected with the connecting rod, the lower end of the connecting plate body is connected with the horizontal hook part, and preferably, the connecting rod, the connecting plate;
the right-angle draw hook comprises a vertical plate body, a horizontal plate body and an arc-shaped bent handle plate which are sequentially connected, wherein the vertical plate body is vertical to the horizontal plate body, the upper end of the vertical plate body is connected with the horizontal plate body, the left side and the right side of the lower end of the vertical plate body are arc surfaces, the middle part of the lower end of the vertical plate body is a horizontal plane, and preferably, the vertical plate body, the horizontal plate body and the arc-shaped bent handle plate are integrally;
the round wood handle design of the round handle drag hook can lead the time for the human body to hold the fist and bend the elbow drag hook for a longer time, and is more labor-saving. Simultaneously the end of round handle drag hook has the crotch of 0.5CM to handle (horizontal hook portion promptly), draws muscular tissue to spinal central line when more being favorable to the flesh interval approach, avoids the drag hook to slide from top to bottom simultaneously, and the connecting plate body openly is isosceles trapezoid, reduces the shadowless lamp and shelters from the area, more is favorable to the operation of operator, and the riser body of right angle drag hook is sharp most advanced because of no vertebral plate drag hook, and the lower extreme left and right sides is the arc surface, for blunt nature, diminishes to the damage of flesh interval outside tissue.
In this embodiment, the cylindrical handle is a wooden handle, and the vertical plate, the horizontal plate, the arc-shaped bent-handle plate, the connecting rod, the connecting plate and the horizontal hook are all made of metal.
In this example, studies have shown that the L1-5 vertebral body posterior edge has an average height of 2.474 cm and the thoracic vertebral body posterior edge has an average height of 1.917 cm. Therefore, when the vertebral plate is decompressed and the muscle gap enters the way, the surgical area can be fully exposed only by exposing the space range of 2-2.5 CM, and the width of the vertical plate body of the right-angle drag hook is selected to be two specifications of 2CM and 2.5 CM.
In this embodiment, the width of the lower end of the connecting plate body is 1.5cm or 2.0cm, the height of the connecting plate body is 12cm, the width of the connecting rod is equal to the width of the upper end of the connecting plate body, the length of the connecting rod is 13cm, the length of the horizontal hook portion is 0.5cm, the length of the cylindrical handle is 10cm, the diameter of the cylindrical handle is matched with actual requirements, and the connecting plate body can be repeatedly held by hands.
In this embodiment, the length of the vertical plate body is 7cm or 8cm, the width is 2cm or 2.5cm, the depth and the width of two sizes and specifications of the vertical plate body can be just flexibly adjusted with the height, the length, the thickness and the thinness of the Chinese, the width of the transverse plate body is the same as that of the vertical plate body, and the length of the transverse plate body is 21 cm.
In this embodiment, the end of the arc-shaped curved handle plate is provided with a bending portion bent toward the vertical plate body.
In this embodiment, the right angle drag hook is the sheet metal component, and it is through a plate body integrated bending shaping.
