Abstract
The utility model relates to a decompression ring for operative treatment on intracranial prosopalgia. The decompression ring is a longitudinally opening sponge ring, the cross section of the decompression ring is C-shaped, and the opening gap of the decompression ring is 0.1-3mm. The decompression ring for operative treatment on intracranial prosopalgia provided by the utility model is used for separating and isolating the blood vessels which press the intracranial nerves at the brainstem in the neurocranium operations, so that the blood vessels pulsate to percussion the root of nerves no longer, and the pain of a patient is relieved greatly. By utilizing the decompression ring, the labor intensity of doctors is reduced, operations can be more normalized and standardized, and simultaneously, the decompression ring has the advantages of being convenient to use, clean, excellent in cushioning and relatively light in weight, and the like.
Description
Technical field
This utility model relates to the pressure-reducing ring that a kind of operative treatment intracranial trigeminal neuralgia is used.
Background technology
Trigeminal neuralgia refers to occur in having an intense pain in the facial nervi trigeminus distributed areas, is the insufferable nervous system disease of ordinary person as a kind of cut-like pain.Age of onset is many after 40 years old, and the woman is more than the man.Pain is periodical attack, and patient even saliva also dare not be swallowed during outbreak, has affected normal live and work, thereby is called as " the first under heaven pain ".
Cause that trigeminal neuralgia has many reasons, one of its reason is that nervi trigeminus has been subject to cerebrovascular compressing, has caused regular pain.The treatment trigeminal neuralgia mainly contains Drug therapy, gamma knife treatment, microvascular decompression operative treatment and this several method of Radiofrequency treatment, but for the affected nerves of patients with trigeminal neuralgia that is subject to perstriction, the microvascular decompression operation is to use at present more widely technique of surgical treatment, has become the prosopalgic standard method for the treatment of.
MVD is at microscopically the brain stem place to be oppressed trifacial blood vessel and arachnoidea bar rope to push aside and isolate, and makes beating of blood vessel no longer tunk nervi trigeminus.In case the responsibility blood vessel is isolated, produce the root that stimulates and also be isolated simultaneously, trigeminal neuralgia has just disappeared immediately.
At present decompression isolated material commonly used is to make a certain size isolation bed course at operative site according to the affected part situation with floccule (as: fiber that the dacron patch of using from department of cardiac surgery is torn), with the generation cushioning effect.The defective of this kind method is: the pressure-reducing pad plate shape that do at the scene has certain randomness, and cushioning effect can't standardization, the operation relative complex, and spended time is partially long.The people such as Li Shiting [Li Shiting etc., a kind of decompression material cartridge that is used for the treatment of all kinds of cranial nerve syndromes, 201120121755.9] designed a kind of prosopalgic decompression material cartridge that can be used for treating, operation is placed in the material cartridge by different sizes with the decompression cotton-wool, its advantage is accurately to control the size of decompression material, omitted on-the-spot process of tearing floccule preparation decompression pad in operation, operated efficient and convenient to some extent; And weak point is, the polarization of this decompression material is relatively poor, might reset and the flowing and the decompression position that slips away of cerebrospinal fluid along with postoperative cerebral tissue, causes effect of easing stress decline even reduces pressure unsuccessfully.
Summary of the invention
Technical problem to be solved in the utility model provides the pressure-reducing ring that a kind of operative treatment intracranial trigeminal neuralgia is used, and the application of this pressure-reducing ring is being so that the doctor is carrying out microvascular decompression when operation more convenient operation, and operation process normative standard more.
The pressure-reducing ring that a kind of operative treatment intracranial trigeminal neuralgia of the present utility model is used have more standardization of the operation of making, standardization, easy to operate, use cleaning, resiliency good, with advantages such as specific mass are light.The doctor can with blood vessel with after nervi trigeminus separates, the pressure-reducing ring of clip suitable length only needs this pressure-reducing ring is enclosed within the effect that can play isolation buffer on the blood vessel as required.The good elasticity of sponge has guaranteed effective isolation effect; Loop configuration be so that pressure-reducing ring can firmly be enclosed within blood vessel outside, makes the slip away generation of decompression position phenomenon of insulating wool sheet along with postoperative cerebral tissue resets with cerebrospinal fluid mobile when having prevented from using the traditional cotton sheet; The pressure-reducing ring of different model so that the doctor can select according to field condition easily; The integrated structure of pressure-reducing ring is not easy to produce chip, and spatter property is good; Foam sponge is except good springiness, and is also relatively light and handy, more favourable to patient's rehabilitation; Need not on-the-spot processing so that operating time shortens dramatically, alleviated doctor's labor intensity.
The pressure-reducing ring that a kind of operative treatment intracranial trigeminal neuralgia of the present utility model is used is the sponge ring of longitudinal opening, and its shape of cross section is " C " shape, and aperture slots is 0.1～3mm.The sponge ring refers to the ring made take foam sponge as material, and sponge is formed by a kind of foaming in polyurethane, polyethers, rubber, the polyester; Shape of cross section is " C " shape structure so that pressure-reducing ring can firmly be enclosed within blood vessel outside, makes the slip away generation of decompression position phenomenon of insulating wool sheet along with postoperative cerebral tissue resets with cerebrospinal fluid mobile when having prevented from using the traditional cotton sheet.As a rule, " C " shape structure of pressure-reducing ring is conducive to grip the responsibility blood vessel; Material takes foam sponge can play well cushioning effect, and sponge has preferably skin-friction force in addition, is not easy along the slippage of responsibility blood vessel; Aperture slots is to be enclosed within responsibility blood vessel outside be used to breaking annulus into two with one's hands, and aperture slots is designed to 0.1～3mm and is used on the responsibility blood vessel of different-diameter for the ease of the pressure-reducing ring with same diameter.
The pressure-reducing ring that aforesaid a kind of operative treatment intracranial trigeminal neuralgia is used, the length of described pressure-reducing ring is 5～50mm, and wall thickness is 1～5mm, and internal radius is 1～5mm.The pressure-reducing ring Design of length becomes 5～50mm to cut out according to the concrete condition that runs in the operation for the ease of the doctor, in general 5mm length can have been set up a reduction points, just can reach therapeutic effect but sometimes need to set up several reduction points, therefore long pressure-reducing ring is more convenient concerning the doctor; It is in order to adapt to different patients' concrete clinical needs that the pressure-reducing ring internal diameter is designed to 1～5mm; It is in order to adapt to the needs of different responsibility blood vessels that wall thickness is designed to 1～5mm, though the thicker effect of easing stress of tube wall is better, sometimes be limited to the pressure-reducing ring that less wall thickness can only be used in the space, so wall thickness should be designed to series.
Beneficial effect
The pressure-reducing ring that a kind of operative treatment intracranial trigeminal neuralgia of the present utility model is used is used for separating and isolation at the blood vessel of brainpan operation with brain stem place compressing intracranial nerve, makes beating of blood vessel no longer tunk nerve root, has greatly alleviated patient's misery.The use of pressure-reducing ring has reduced doctor's labor intensity so that more standardization, standardization of operation, have simultaneously easy to use, cleaning, resiliency good, with advantages such as specific mass are light.
