Spinal operation assisting device

Abstract

The invention relates to the field of medical treatment, in particular to a spinal operation assisting device which comprises a sleeve and an inserting needle. The sleeve comprises a hollow tubular structure, the inserting needle can penetrate the tubular structure and comprises a protruding inserting needle end, a positioning nail can penetrate in the tubular structure and comprises a pinnacle, a body portion with a thread in the middle, a deboss at a non-pinnacle end, and a mounting handle capable of being matched with the deboss in an embedded manner, the mounting handle comprises a handle rotating handle and a rotating head, and the rotating head comprises a protrusion and can be fitted with the deboss of the positioning nail. The spinal operation assisting device has the advantages of capability of realizing accurate positioning, convenience and safety in use, small wound, easiness in rehabilitation and less proneness to causing complication.

Description

technical field [0001] The invention relates to the medical field, in particular to an auxiliary device for spinal surgery. Background technique [0002] Spinal surgery requires precise positioning, because lesions are often located inside the spinal canal. Inaccurate positioning not only makes it difficult to find lesions, but also requires opening more unnecessary spinal segments, which can easily lead to loss of spinal stability. [0003] During posterior spinal surgery, especially thoracic and thoracolumbar surgery, repeated fluoroscopy is often required due to the difficulty in determining the lesion segment, which not only brings more radiation damage to the patient, affects the operation process, and even causes positioning errors, spinal nerves, etc. Complications such as injury.

Problems solved by technology

[0002] Spinal surgery requires precise positioning, because lesions are often located inside the spinal canal. Improper positioning not only makes it difficult to find lesions, but also requires opening more unnecessary spinal segments, which can easily lead to loss of spinal stability

[0003] During posterior spinal surgery, especially thoracic and thoracolumbar surgery, repeated fluoroscopy is often required due to the difficulty in determining the lesion segment, which not only brings more radiation damage to the patient, affects the operation process, and even causes positioning errors, spinal nerves, etc. Complications such as injury

For the operating room without intraoperative X-ray fluoroscopy, the vertebral body can only be positioned by X-ray inspection after the body surface is touched or the body surface is pasted with markers before the operation. Or skin displacement leads to positioning errors, which will eventually bring additional complications such as spinal bone and even spinal nerve injury to the patient

[0004] There are many traditional spine positioning methods, and each has its own limitations: (1) The positioning method of the anterior superior iliac spine is likely to lead to misjudgment for obese or degenerated patients with unclear spinous process gaps, and this positioning method relies on the experience of doctors

(2) The rib positioning method has higher requirements on the clarity of preoperative X-ray films and intraoperative fluoroscopy

However, due to the inconsistency between the intraoperative body position and the photographic body position or the movement of the skin, the position of the skin mark and the corresponding position of the bony spinous process is not very accurate, especially for obese patients, the error is even greater
