Description
Technical Field
The invention relates to the field of medical instruments, in particular to a trigeminal balloon catheter and a use method thereof.
Background
Trigeminal neuralgia, which is considered to be the most severe painful disease suffered by humans to date, is characterized by severe facial paroxysmal pain at the onset, and the frequency of attacks seriously affects the quality of life of the patient. The prevalence rate of the trigeminal neuralgia is 182/10 ten thousands of people, about 200 thousands of cases occur in China every year, and the middle-aged and old people are more common, and if the price of the product is 10000 yuan per set, the market value is about 200 million yuan. Trigeminal neuralgia is classified into primary trigeminal neuralgia and secondary trigeminal neuralgia. The etiology and pathogenesis of primary trigeminal neuralgia are unknown, and the disease is generally considered to be related to demyelination of nerve roots or brain stem parts of trigeminal sensory roots. This demyelination is primarily due to compression of adjacent arterial or venous vessels, and may be due to multiple sclerosis or other causes. When the nerve root of the trigeminal neuralgia patient stressed by the blood vessel is explored in the operation, the demyelination of the stressed part can be found. The secondary trigeminal neuralgia mainly refers to organic lesions existing in or around trigeminal nerve, and is mainly caused by the space-occupying lesion of the pontine and cerebellum, the space-occupying lesion of the semilunar ganglion and the vascular malformation. Experimental studies have demonstrated that spontaneous abnormal nerve impulses caused by anatomical changes associated with vascular compression can be transmitted to adjacent nerve fibers, and that pain disappears almost immediately after vascular compression is relieved, as also demonstrated clinically.
The primary trigeminal neuralgia treatment methods comprise percutaneous trigeminal ganglion temperature control radio frequency thermal coagulation treatment, percutaneous trigeminal ganglion micro-balloon compression, adriamycin, alcohol or glycerol trigeminal ganglion blocking treatment, trigeminal peripheral branch avulsion, trigeminal sensory root cutting, trigeminal root microvascular decompression, stereotactic radiosurgery gamma-knife treatment and the like, and various treatment means have certain curative effect.
The trigeminal nerve root microvascular decompression is considered to be the only treatment method aiming at the etiology at present, and the clinical curative effect of the trigeminal nerve root microvascular decompression is widely accepted. The percutaneous trigeminal ganglion micro-balloon compression method can keep the integrity of the physiological structure of the trigeminal nerve without damaging the nerve, thereby not influencing the normal feeling of the face. The advantages of percutaneous minimally invasive treatment are simple operation and small wound.
The operation needs to be performed under general anesthesia, has special puncture parts and operation technical requirements, is applied more abroad at present, and is performed in few hospitals in China. And no balloon catheter suitable for the indication appears in the market at present, and other balloons which are not suitable for the indication are generally used at home and abroad, such as a Fogarty thrombus-taking balloon catheter or a balloon catheter kit (single balloon) for brain surgery to perform the surgery. The single balloon catheter penetrates into the semilunar ganglion after puncture under the irradiation of X rays and compresses the semilunar ganglion at present, the single balloon structure is single and rigid, the compression mode is not targeted, pressure can be applied only according to the preset shape of the single balloon, and the pressure cannot be increased directionally, so that the use effect is poor.
The single pressure balloon is not oriented to the compression around the Mylar sac (trigeminal nerve), and the balloon pressure is increased only by matching the pressure pump, so that the orientation of the balloon pressure cannot be formed. Therefore, the development of the trigeminal balloon with adjustable pressure can increase the pressure of the trigeminal semilunar ganglion part, meets the clinical requirements, and is the key development direction of research and development personnel.

As shown in fig. 1-3, the present embodiment discloses a trigeminal balloon catheter, which includes a catheter 1 and a balloon connected to an end of the catheter 1, the balloon includes an outer balloon 2 and three inner balloons 3 disposed in the outer balloon 2, a plurality of lumens 11 are disposed in the catheter 1, distal ends of the lumens 11 are in one-to-one communication with the outer balloon 2 and the inner balloons 3, and proximal ends of the lumens 11 are connected to different injection devices through the catheter 1. Where the end of the instrument closer to the operator is defined herein as the proximal end and the end farther from the operator is defined herein as the distal end. The cavity tube 11 is used for filling or discharging filling media into or from the corresponding outer balloon 2 or inner balloon 3, so that the outer balloon 2 and the inner balloon 3 are combined to form different filling shapes and pressures, the different filling shapes and pressures can flexibly meet the requirements of different tissue structures of a diseased part when the trigeminal nerve meniscus is compressed, the directionality of the pressure provided by the balloons to the diseased part is improved, the meniscus is subjected to targeted compression treatment, and the treatment effect is improved.
In order to facilitate accurate balloon delivery to the treatment site, the lumen 11 is further provided with a mounting channel 12 along the same extending direction of the lumen 11, and the mounting channel 12 is used for mounting a support (not shown in the figure), so that the catheter 1 has certain rigidity, which facilitates balloon delivery at the distal end of the trigeminal balloon catheter to the treatment site, and increases maneuverability. In this embodiment, the support member is a steel wire having both rigidity and flexibility. In other alternative embodiments, the support member may be made of a non-metallic material.
As shown in fig. 1, in this embodiment, since three inner balloons 3 and one outer balloon 2 are provided, the pressure between each inner balloon 3 and each outer balloon 2 may be set to be the same or different, the pressure of each balloon may be adaptively adjusted according to the difference of the tissue structure of the treatment site to meet the different pressure requirements of the treatment site, and high pressure or low pressure may be sequentially injected into different balloons to meet the treatment requirements of high pressure first and low pressure second or low pressure first and high pressure second of the lesion site, so as to provide the treatment site with a shape and pressure adjusted in real time, and meet the diversified requirements in the operation.
Wherein, the filling medium can be gas or liquid. The inflation medium of gas or liquid facilitates inflation or deflation of the different balloons as desired. Since the gas has a certain compression ratio, by filling different amounts of gas, more precise pressure values which gradually increase or decrease can be provided to the lesion site.
In this embodiment, the filling medium is a contrast medium which can be visualized or visible under X-ray, so that the doctor can observe and operate the device conveniently in the operation, thereby improving the accuracy of the operation.
In the present embodiment, the outer balloon 2 has elasticity. Because outside sacculus 2 wraps up inside sacculus 3, under the circumstances that all sacculus do not fill into sufficient medium, the outside sacculus 2 of elastic material makes all sacculus all attach in the outer wall of pipe 1 and ensure that whole sacculus is outside level and smooth, easy propelling movement for the sacculus has better compliance, and the port of putting into the wheat's capsule through the sheath pipe with the sacculus pipe after being convenient for puncture is with accurate arrival treatment position. Simultaneously, the outer sacculus 2 of elasticity material is along with filling the increase of medium, and the volume can constantly expand to the tissue inner wall of treatment position is laminated better.
In this embodiment, the inner balloon 3 has no elasticity. Because the inner balloon 3 is arranged inside the outer balloon 2, after the inner balloon 3 is filled with the filling medium, the inner pressure gradually increases along with the increase of the filling medium, and a higher pressure value can be provided for the treatment part. If the inner balloon 3 is elastic, its volume will expand continuously with the increase of the filling medium, and the outer balloon 2 will be burst.
Preferably, the internal pressure that the inner balloon 3 can withstand is not less than the internal pressure that the outer balloon 2 can withstand, facilitating the provision of different pressure values. The filling medium filled in the inner balloon 3 can provide a higher pressure value for the treatment site than the outer balloon 2, and the filling medium filled in the outer balloon 2 can provide a lower pressure value for the treatment site than the inner balloon 3, so that the selection can be conveniently carried out according to the treatment requirement.
In this embodiment, the outer balloon 2 can withstand an internal pressure in the range of 600-1000 mmHg, which can satisfy most of the relatively low pressure requirements for trigeminal therapy. The internal pressure range that interior sacculus 3 can bear is 1000-1300 mmHg, can satisfy the great pressure value demand of most relatively in trigeminal treatment.
The sizes of the outer balloon 2 and the inner balloon 3 and the values of the pressure range to be born can be customized according to the needs of users.
As shown in fig. 4, the present embodiment also discloses a method for using the balloon catheter for trigeminal nerve as described above, which includes the following steps:
step S1, under X-ray perspective monitoring, the puncture needle and the sheath are firstly punctured into the semilunar junction of the trigeminal nerve;
step S2, withdrawing the puncture needle, remaining the sheath at the puncture part, and placing the trigeminal nerve saccule conduit into the port of the Mycoplasma gondii through the sheath;
step S3, filling or discharging filling media into or out of the outer balloon 2 and/or the inner balloon 3, so that the outer balloon 2 and the inner balloon 3 are combined to form different filling shapes and pressures to flexibly match the requirements of different tissue structures when the trigeminal nerve meniscus is compressed;
step S4, after the operation, the contrast agent of the outer balloon 2 and the inner balloon 3 is emptied and the trigeminal balloon catheter is retracted, and then the operation point is subjected to transient compression hemostasis.
In step S3, according to the shape of the different tissue structures of the port of the patient' S mcluses, the filling medium is respectively filled into or discharged from the inner balloon 3 and/or the outer balloon 2, so that the filled inner balloon 3 and the filled outer balloon 2 are combined to form different filling shapes and pressures, and the different filling shapes and pressures flexibly match the requirements of different tissue structures when the trigeminal semilunar ganglion is compressed, thereby adaptively compressing the trigeminal semilunar ganglion, releasing the clamping pressure of the nerve fibers causing trigeminal neuralgia, and causing structural damage to the nerve fibers by the expansion and compression of the balloons, so as to perform targeted treatment on different nerve root fibers of trigeminal neuralgia and play a role in treating trigeminal neuralgia.
When high pressure is required at the target expansion site, the inner balloon 3, which is relatively high in pressure, may be inflated first, and the outer balloon 2, which is relatively low in pressure, may be inflated. When the target expansion part needs low-pressure expansion and then local high-pressure expansion, the external balloon 2 with relatively low filling pressure can be filled firstly, and after the target expansion part meets the requirement, the internal balloon 3 with relatively high filling pressure can be filled, and the whole treatment process can be completed only by adjusting the opening sequence of the balloons. The entire procedure is usually completed within 15 minutes. Thus, the trouble of replacing different balloons and iatrogenic injuries to the patient during treatment are reduced, and accordingly, the operation cost can also be reduced.
