Description

Net sleeve gasket for neurosurgery microvascular decompression

Technical Field

The utility model relates to the field of medical equipment, concretely relates to net cover gasket for neurosurgery microvascular decompression technique.

Background

Trigeminal neuralgia is called painful convulsion, is a common disease of middle-aged and elderly people, has the incidence rate of 180/10 ten thousand, and is mainly manifested by paroxysmal laceration-like severe pain which is repeatedly attacked by a facial trigeminal nerve distribution area. Trigeminal neuralgia is mostly started from one maxillary branch or mandibular branch, gradually spreads to two branches or even three branches, the clinical manifestations of patients are mostly changed from typical to atypical along with the development of the course of disease, the pain is hard to endure during the attack, even daily activities such as eating and brushing teeth can not be carried out, and the life quality of the patients is seriously influenced.

At present, there are many ways of treating trigeminal neuralgia clinically, such as drug therapy, but the drug usually takes effect slowly, and treats the symptoms but not the root causes, and the problem cannot be solved fundamentally; additionally to surgical treatment, microvascular decompression (MVD) is a common method of treating trigeminal neuralgia, which ensures that normal nerve function can be preserved. Part of patients can also eliminate the hypertension state caused by the blood vessel pressing the brain stem, thereby achieving the purpose of radically treating the hypertension. Therefore, the microvascular decompression has the advantages of obvious effect, less damage, extremely low recurrence rate and the like, so that the method is the safest and most effective method for treating the trigeminal neuralgia internationally acknowledged at present.

The specific method of the microvascular decompression is as follows: under the general anesthesia state, the nerve trunk enters into the cerebellum area of a patient under a microscope, the trigeminal nerve walking area is explored, all possibly-compressed responsible vessels and arachnoid cord are loosened, the responsible vessels are isolated from nerve roots through gaskets, once the responsible vessels are isolated, the root source of stimulation disappears, the excitation of the trigeminal nerve roots disappears, and the trigeminal nerve roots are recovered to be normal. Although microvascular decompression has been accepted by doctors and patients at home and abroad, the operation still has the probability of ineffectiveness and recurrence to different degrees, and researches show that the recompression of responsible vessels caused by improper gasket size, improper gasket material selection, gasket falling off, displacement and the like is a main reason of recurrence.

Currently, the size, shape, dimension, and the like of a pressure-reducing material used in a microvascular decompression operation are not uniformly specified, and a doctor needs to tear or trim the pressure-reducing material into a desired size and shape during the operation. However, the pressure reducing material made by temporary tearing or trimming has great randomness when being used in the operation and often needs to be repeatedly made again, which not only prolongs the operation time, but also invisibly increases the risk of blood vessel and nerve injury, adds the uncertainty of the operation and directly influences the probability of ineffective and recurrent operation. In addition, the loose, slipping, shifting, too large, too small, etc. of the decompression gasket all affect the success probability of the operation, once the surgery is recurred, the operation needs to be performed again, and the physical and economic burden is caused to the patient.

Therefore, there is a need in the art for a novel gasket for neurosurgical microvascular decompression, which can effectively avoid the risks of loosening, falling off, displacement and the like after implantation, reduce the probability of ineffective and recurrent operations, and improve the efficacy of microvascular decompression.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the net sleeve gasket for the neurosurgery microvascular decompression effectively avoids the risk of loosening the polytetrafluoroethylene cotton-like fibers by arranging the polytetrafluoroethylene net bag, thereby greatly reducing the problem of operation recurrence caused by loosening and slipping of the whole gasket; additionally, the utility model discloses the gasket is with responsibility blood vessel parcel back in the art, through sewing up gasket joint department, plays further fixed action, reduces the gasket equally effectively and drops, shifts and cause the invalid risk of operation and relapse.

2. The utility model discloses can design the polytetrafluoroethylene pocket that provides multiple dimensions, make things convenient for the art traditional chinese medicine to take root and select different specification and dimension's pocket according to patient's needs in a flexible way, and simultaneously, the thinness of gasket, fluffy degree is filled into the cotton-like fibre of different amount of polytetrafluoroethylene by the doctor as required, need not the doctor through tearing or pruning the shape and the size that the gasket adjusted the gasket, unnecessary operation in the art has not only been reduced, improve operation efficiency, and simultaneously, the gasket of making can satisfy different thickness vascular various circumstances in the microvascular decompression art, avoid too big because of the gasket, lead to the operation inefficacy or too thick, the risk of relapse.

3. The net sleeve gasket for the neurosurgery microvascular decompression adopts the stretched and expanded polytetrafluoroethylene material, the material has hydrophobicity, and the risk of pressure rise and nerve or blood vessel compression caused by effusion formed by absorbing a large amount of water after implantation is avoided; and the polytetrafluoroethylene material has good biocompatibility and is not absorbable, so that the invalid operation and the recurrence risk caused by poor biocompatibility and the absorption of the gasket by a human body after long-term use are effectively avoided.
