Description

Self-made simple sleeve for neuroendoscopy operation

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a simple and easy neural scope sleeve for operation of self-control.

Background

Neuroendoscopy is a tool for observation and operation in endoscopic neurosurgery. As early as 1806, Philipp Bozzini invented endoscopes and gradually became available for clinical use in multiple specialties. In 1918, Dandy observed the ventricles using a cystoscope and named the endoscope "neuro-endoscope". The neural endoscope commonly used in clinic includes a hard endoscope and a soft endoscope, and the latter develops through two stages of an optical fiber endoscope and an electronic soft endoscope. Neuroendoscopic surgery has become one of the major development directions in modern minimally invasive neurosurgery.

Neuroendoscopy surgery has three advantages over surgical microscopes:

1. endoscope sight tube itself has side view angle, can eliminate intraoperative field blind area. The neuroendoscopy assisted neuromicrosurgery overcomes many dead angles of the neurosurgery in vision, and enables the operation to be more precise and better in effect. When the lesion is reached, a panoramic view can be obtained, the lesion is 'closed up', the image is enlarged, important nerve and blood vessel structures on the side and around the lesion are identified, and surrounding lesion tissues are guided to be cut off. Angled endoscopes show the corners of the pons cerebellar triangle, basal ganglia, etc., which some surgical microscopes cannot reach. In addition, the operation under the direct vision of the neuroendoscope can avoid the bleeding caused by blind puncture.

And 2, the tissue can be accurately positioned by means of stereotactic or neuronavigation technology, can process the parts which are difficult to reach in the conventional operation, and is particularly suitable for pathological operation of deep brain or midline parts. In a deeper surgical field, the brightness of a light source of the surgical microscope is attenuated, and the neuroendoscopy system performs short-distance illumination, although the stereoscopic impression of the image is slightly different from that of a microscope image, the definition degree of the deep surgical field is obviously superior to that of the surgical microscope.

3. neural endoscope is more suitable for entering with ossicle window, and the operation is less invasive. The neuroendoscopy diameter is different from 0.6-6 mm, the brain tissue damage is very small, and the majority of neuroendoscopy operations adopt a ossicle window approach, so the brain tissue trauma caused by the bone flap craniotomy is avoided. The endoscope has long body and small cross section, and is suitable for operation in narrow cavity and duct. These properties of neuroendoscopy help to better visualize lesions or important structures around the cranium, and are particularly helpful in deep lesion manipulation (e.g., basilar aneurysms) in the narrow space of microsurgery, to reduce the scope of craniotomy and avoid excessive exposure. The operation microscope can increase local illumination and the brightness is softer.

In the prior art, a working channel (cannula) needs to be established in part of neuroendoscopy, the endoscopy usually places a proper cannula in a lesion cavity and can cut (clear) the cannula in the inner space, and the smaller the outer diameter of the used cannula is, the less invasive the brain parenchyma is, the larger the inner diameter is, and the easier the operation is. The clinical general opinion is that transparent outer tube is more convenient to hematoma chamber wall condition observation, and electric coagulation ware and aspirator can be put into to this sleeve pipe, need not continuously wash the scope, make the operation more simple and convenient, and the transparent pipeline is convenient for observe, makes hemostasis more thoroughly.

The price of partial casing pipes applied in the market is expensive, the casing pipes cannot be popularized and limited in primary hospitals, the diameter of partial casing pipes is large, the damage to surrounding brain tissues is large, the length of partial casing pipes is not enough, the pathological changes cannot be effectively achieved, the operation is influenced, and even more structural damages are caused.
