Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a balloon compression needle. Background Art

[0002] Hemifacial spasm, also known as hemifacial spasm, refers to repeated involuntary contractions, tonic spasms, and linkages of the facial muscles innervated by one facial nerve. Hemifacial spasm often begins in the orbicularis oculi muscle and then gradually spreads to other muscles innervated by the same facial nerve. Although hemifacial spasm is generally considered a benign disease, involuntary facial twitching can lead to social embarrassment and withdrawal, and in severe cases, functional blindness due to involuntary eye closure.

[0003] At present, the treatment options for hemifacial spasm mainly include the following: (1) local injection of botulinum toxin, but the relief of symptoms of facial spasm by botulinum toxin injection is limited and short-lived, and the efficacy is generally only about 3 months; (2) craniotomy and microvascular decompression surgery (MVD), which can effectively treat hemifacial spasm, but it needs to be performed under general anesthesia and requires entering the skull for operation. There are many complications related to the surgery, which is not easy for patients to accept; (3) facial nerve radiofrequency treatment, which is to insert the radiofrequency puncture needle into the outlet of the facial nerve at the stylomastoid foramen under CT guidance. The principle of electric couple is used to generate heat energy between nerve fibers through radiofrequency current, and the temperature is controlled to cause the nerve to be thermally coagulated and denatured, blocking part of the conduction function of the facial nerve, so that the abnormal excitement cannot be fully transmitted to the effector (expression muscle), thereby preventing the occurrence of hemifacial spasm and retaining part of the function of the expression muscle to prevent severe facial paralysis. During facial nerve radiofrequency ablation, an external radiofrequency device is usually used to achieve the treatment effect by adjusting the current, temperature, and time, and observing the changes in the patient's face. The treatment equipment and process are relatively complicated. Because its treatment mechanism is to thermally coagulate and deform the facial nerve with conduction abnormalities (i.e., destroy the nerve), there will be certain side effects. If the treatment effect cannot be achieved, it is necessary to adjust the needle tip position or change the puncture path before testing and radiofrequency treatment. Therefore, multiple tests are required during facial nerve radiofrequency treatment. Repeated radiofrequency treatment during the test may cause further damage to the patient's health. Summary of the invention

[0004] In order to overcome the defects in the prior art, the task of the present invention is to provide a balloon compression needle for treating hemifacial spasm which has a simple structure and is easy to operate.

[0005] The task of the present invention is achieved through the following technical solutions:

[0006] A balloon compression needle comprises a puncture needle tube, a needle is provided at the front end of the puncture needle tube, a side hole is provided on the side wall of the puncture needle tube near the needle, the side hole is covered with an elastic diaphragm, the side edge of the elastic diaphragm is sealed and connected to the puncture needle tube, and injecting a filling agent into a filling channel can cause the elastic diaphragm to expand and arch outward through the side hole to form a balloon structure, and extracting the filling agent can restore the elastic diaphragm to be flat on the puncture needle tube.

[0007] As a preferred technical solution, the side wall of the puncture needle tube is provided with a groove, the elastic diaphragm is embedded in the groove, and the side hole is provided at the bottom of the groove.

[0008] As a preferred technical solution, the tail end of the puncture needle tube is provided with a Luer connector, through which a syringe can be connected to inject or extract the filling agent into the puncture needle tube.

[0009] As a preferred technical solution, the elastic membrane is a sheet-like structure, or a ring-like structure surrounding the side circumference of the puncture needle tube.

[0010] Compared with the prior art, the balloon compression needle provided by the present invention has the following beneficial effects:

[0011] The balloon compression needle provided by this patent is provided with an elastic diaphragm on the puncture needle tube. When in use, after the puncture needle tube reaches the designated position, a filling agent (gas or liquid) is injected into the puncture needle tube, so that the elastic diaphragm on the puncture needle tube can bulge out to form a soft balloon. The puncture needle tube is adjusted by external operation to drive the soft balloon to compress the inner surface of the stylomastoid foramen, which can block part of the conduction function of the facial nerve, thereby achieving the treatment of facial muscle spasm. Moreover, compared with the facial nerve radiofrequency treatment device, the structure of this patent is simpler, the operation is easier, and the treatment process has fewer side effects on patients.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the "first", "second" and similar words used in the specification and claims of this application do not indicate any order, quantity or importance, but are only used to distinguish different components. "Connected" or "connected" and similar words should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate element. It is not limited to physical or mechanical connections, and can include electrical connections. For those of ordinary skill in the art, the specific meanings of the above words in this application can be understood according to specific circumstances.

[0023] Embodiment 1:

[0024] like Figure 1-6 As shown, this embodiment provides a balloon compression needle, including a puncture needle tube 1, a needle 2 is provided at the front end of the puncture needle tube 1, a side hole 11 is provided on the side wall of the puncture needle tube 1 near the needle 2, and a sheet-like elastic membrane 3 is covered on the side hole 11. The side edge of the elastic membrane 3 is sealed with the puncture needle tube 1. Injecting a filling agent into the puncture needle tube 1 can cause the elastic membrane 3 to expand and arch outward through the side hole 11 to form a hemispherical balloon structure, and extracting the filling agent can restore the elastic membrane 3 to be flat on the puncture needle tube 1.

[0025] The balloon compression needle is used to treat hemifacial spasm, which mainly includes the following steps:

[0026] S1: Insert the balloon compression needle according to the puncture angle and pass through the stylomastoid foramen;

[0027] S2: Inject the filling agent into the puncture needle tube 1 to make the elastic membrane 3 expand outward to form a balloon, and then operate the puncture needle tube 1 so that the balloon presses the inner surface of the stylomastoid foramen.

[0028] The balloon compression needle provided by this patent has a puncture needle tube 1 that is made of metal like a conventional puncture needle. The biggest difference is that an elastic diaphragm 3 is provided on the puncture needle tube 1. During the treatment operation, after the puncture needle tube 1 is punctured to the designated position, a filling agent (gas or liquid) is injected into the puncture needle tube 1, so that the elastic diaphragm 3 on the puncture needle tube 1 can be protruded to form a soft balloon. By adjusting the puncture needle tube 1 through external operation, the soft balloon is driven to compress the inner surface of the stylomastoid foramen, thereby blocking part of the conduction function of the facial nerve, and achieving the same therapeutic effect as the radiofrequency treatment of the facial nerve. Moreover, compared with the radiofrequency treatment of the facial nerve, the structure of this patent is simpler, the operation is easier, and the treatment process has fewer side effects on patients.

[0029] As a preferred solution of this embodiment, the outer wall of the puncture needle tube 1 is provided with a groove 12, the elastic membrane 3 is embedded in the corresponding groove 12, and the side hole 11 is provided at the bottom of the groove 12. This solution enables the elastic membrane 3 to be embedded in the groove 12 when it is not expanded, so that the outer diameter of the puncture needle tube 1 will not be increased, and the puncture process will not be affected.

[0030] As a preferred solution of this embodiment, the front end of the puncture needle tube 1 and the needle 2 thereon are bent at a certain angle, and the elastic membrane 3 is located at the bent position.

[0031] As a preferred solution of this embodiment, the tail end of the puncture needle tube 1 is provided with a syringe that can be connected via a Luer connector 4 to inject or extract the filling agent into or from the puncture needle tube 1 .

[0032] Embodiment 2:

[0033] Based on the technical solution of Example 1, the following improvements are made:

[0034] like Figure 7-8 As shown, the elastic diaphragm 3 is a ring-shaped structure surrounding the side of the puncture needle tube 1. There are two or more side holes 11 set on the puncture needle tube 1. Injecting filling agent into the filling channel can make the elastic diaphragm 3 expand and arch outward to form a spherical balloon structure, thereby achieving circumferential outward compression.

[0035] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the inventive concept. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this application. It should be noted that when an element is referred to as "connected" to another element, it can be directly connected to another element, or it can be indirectly connected through a central element, depending on the application scenario.
