Description

DESCRIPTION CONSTRUCTION OF GRAFT COATED NITINOL TUBULAR RETRACTOR Technical Area The invention relates to the construction of a graft-coated nitinol tubular retractor.

The invention is particularly relevant for brain tumors and cerebrovascular surgery (aneurysm, mall, cavernoma) as well as in other areas of neurosurgery. which facilitates the microdissection and shortens the operation times, a new graft-coated nitinol tubular retractor that is easy and non-damaging to brain tissue relates to the build.

Invention Background Retractors are known as separators used in surgical operations. retractors The most known and used retractor among them is Dr. Developed by Gazi Yasargil Leyla is a retractor. Regarding the Leyla retractor, which has been used for more than 40 years, Dr. Gazi Yasargil "To the Brain" It is very difficult to enter. Because when you open the skull, the bone will appear like an ingot.

But the place you want to enter is under this ingot. Our teachers in 1920 They were very afraid of this ingot. Those who go first, slowly lift the forehead for the first time, They removed the beard and made Iobartractions, that is, they pulled out the brain lobes. We do this While doing it, the young assistants are given a spatula. The assistant holds it in his hand and It pulls in balance so that the teacher can work comfortably. I learned this from my teacher. Most I just kept 0 spatulas for at least two years. My life has been spent holding it. But 10 minutes then this joint in your hand starts to hurt so don't ask. beat that pain you have to; because you can't stop if you can't beat it. If you can't stop the surgery you block. You have to overcome that pain and do your job. This is a tribute. Aciya to resist. While I was doing this job, I was thinking: why do I do this? because we can't keep it in an automatic way? My daughter was 6-7 years old in those years. of his mother He took the pearl neck collar and tried to put it over his head. Of course at this time The necklace is broken, the pearls are scattered around. cost me. He said look, these are broken. together We went to collect the necklace. I'm on nylon thread for ease I spent pearls. But knotting a nylon thread is very difficult. Does not slip, does not hold, does not sit.

Just at this moment, while I'm pulling a piece of it, what do I see: those beads one by one suddenly it became a whole chain. The resulting chain means a completely different value. Yourself special physical property. It can stand on its own. I said I found it. Instead of spatula that will pass, that can stand on its own. Then they made the 0 beads from steel. into they put on a chain. This chain is called retractor. I gave her the name Leyla." has used. The explanations mentioned are actually the history of the separating tools called retractors. means.

The biggest problem with the aforementioned Leyla retractor is that the metal groin Because it is hard (rigid), it provides the dissection of the brain tissue.

The installation and use of the aforementioned retractors can extend the surgical time; even more After a certain period of time, due to its metal blades, it is found in the brain tissue. damage (contusion) may occur.

Regarding the subject in the European Patent application numbered EP3192553A1 in the literature provides a brain retractor device containing: an expandable saccule, a support tube, a connecting base, a lockable and lockable locking mechanism. a flexible retraction component and expansion or retraction of the expandable sucralus It includes a pressurization device connector configured for pulling. A The brain depressor is sheathed at the distal end of the flexible retractor and avulsed by the flexible retraction component so that the gate remains an avulsal state. enters the courtyard passageway. In the brain retractor device, the locking mechanism is attached to the connection base. is pushed and the expandable sucralular is stretched and the expandable sucralus entering the diseased area becomes thin enough to control its length and position. Moreover, the pressure If the expandable sacculus is expanded and the fluid is drained by injecting fluid into its connector, The expandable saccule is retracted.” statements are included.

Again in the literature, in the US patent application numbered U83766910, “A single-use, self-contained brain and replaceable disposable It is a delicate tissue retractor with blades. The blades can be made in a variety of shapes and sizes and in most cases, to prevent damage to the brain or other soft tissues, and It is designed to be covered with a gauze strip to protect it.” place for statements are given.

In none of the aforementioned applications, the above-mentioned problems are avoided. cannot be passed.
