Polyester cotton for cranial nerve microvascular decompression and application thereof

Abstract

The invention aims at disclosing polyester cotton for cranial nerve microvascular decompression and application of the polyester cotton, the polyester cotton with an unspecific three-dimensional shape is developed, the polyester cotton is of a cotton-fiber-shaped structure and comprises a plurality of wavy polyester fibers, the fineness d of the polyester fibers ranges from 100 D to 200 D, and the fineness d of the polyester fibers ranges from 100 D to 200 D. The number f of filaments of the polyester fibers is equal to (0.2-2) * d, the density of the polyester cotton is 0.003-0.01 g / cm < 3 >, and the filaments of the polyester fibers are in a separated state, the polyester cotton has the advantages that the polyester cotton is soft and fluffy, has certain elasticity, can be shaped at will in the clinical process, can be used in combination with the polyester cotton of different sizes, and has the advantages of being simple in structure and convenient to use. Compared with the prior art, the polyester cotton with the proper size and shape can be quickly selected according to the space structure between the cranial nerve and the cerebral microvessel, the shaped polyester cotton is placed between the cranial nerve and the cerebral microvessel, isolation of the cranial nerve and the cerebral microvessel is achieved, and cranial neuropathy of a patient is treated.

Description

technical field [0001] The invention relates to the technical field of cranial nerve microvascular decompression, in particular to polyester cotton for cranial nerve microvascular decompression and its application. Background technique [0002] Cranial nerves are also called "cranial nerves". There are 12 pairs of cranial nerves in the human body, that is, there are 24 of them. The cranial nerves include the olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, auditory, glossopharyngeal, vagus, accessory, and hypoglossal nerves. [0003] When cranial nerves are compressed by blood vessels, people will experience trigeminal neuralgia, hemifacial spasm, glossopharyngeal neuralgia, masseter muscle spasm, blepharospasm, postural vertigo, Meniere's syndrome, etc., such as trigeminal neuralgia is a recurrent Paroxysmal episodes of severe neuralgia that usually require conservative or surgical treatment. [0004] Conservative treatment is to block nerve transmis...

AI Technical Summary

Problems solved by technology

The defect that the Teflon (polytetrafluoroethylene) gasket exists is that the Teflon (polytetrafluoroethylene) gasket is placed between the microvascular and the cranial nerve, because the gap between the gasket and the cranial nerve and the microvascular The contact specific surface area is small, on the one hand, it is loose and displaced due to vibration and other reasons; The spacer itself can irritate the cranial nerves, causing new ailments

Teflon (polytetrafluoroethylene) cotton is composed of Teflon (polytetrafluoroethylene) fibers. Teflon (polytetrafluoroethylene) fibers themselves are relatively elastic and not easy to bend. It is not easy to shape during clinical use. It is not conducive to making arbitrary shapes to fill the unspecified shape space between cranial nerves and microvessels. After a long time, the fibers in Teflon (polytetrafluoroethylene) cotton will stimulate cranial nerves and cause disease recurrence

Polyester gaskets are similar to Teflon (polytetrafluoroethylene) gaskets in that because the contact specific surface area between the gaskets and cranial nerves and microvascular vessels is small, they will be displaced and fall off due to vibration or other factors. lead to relapse
