Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a puncture assembly for trigeminal ganglion balloon compression surgery under local anesthesia. Background Art

[0002] Balloon compression of the trigeminal ganglion is an effective treatment for intractable trigeminal neuralgia. Punctures are made at the foramen ovale and a balloon is inserted to compress the trigeminal ganglion, significantly alleviating pain symptoms. During this procedure, the accuracy and safety of the anesthesia puncture procedure directly impact the surgical outcome and patient prognosis. High-quality anesthesia puncture components are crucial for a successful procedure.

[0003] In existing trigeminal ganglion balloon compression procedures, the puncture is typically performed in two steps: first, local anesthesia is administered using a local anesthetic needle, then the needle is removed, and the surgical procedure is performed using a specialized puncture kit. This step-by-step puncture method not only increases the patient's pain but can also lead to deviations in the puncture path, compromising the surgical outcome. Furthermore, the existing technology lacks a real-time monitoring device for the pressure within the balloon, making it impossible to precisely control the balloon's inflation level, increasing the risk of postoperative complications. Summary of the Invention

[0004] To address the aforementioned technical issues, the present invention designs a puncture assembly for trigeminal ganglion balloon compression under local anesthesia. During the anesthesia procedure, the anesthetic needle is first used for puncture. After local anesthesia is established, the puncture needle is then placed over the outer portion of the anesthetic needle for puncture. To facilitate needle insertion, the anesthetic needle is detachable. The anesthetic needle is then removed from the puncture needle, and a balloon catheter is inserted into the puncture needle. The balloon is then inflated using a balloon expansion pressure pump while the internal pressure of the balloon is monitored.

[0005] In order to achieve the above technical effects, the present invention discloses a puncture assembly for trigeminal ganglion balloon compression under local anesthesia, comprising: a puncture needle, an anesthetic needle, a balloon catheter, and a balloon expansion pressure pump; the anesthetic needle is detachably and slidably sleeved inside the puncture needle; the balloon catheter is detachably and slidably sleeved inside the puncture needle;

[0006] Furthermore, a balloon is fixedly provided at the front end of the balloon catheter;

[0007] Furthermore, the balloon expansion pressure pump can inject contrast agent into the balloon of the balloon catheter, and the balloon expansion pressure pump can detect the balloon pressure;

[0008] Furthermore, the balloon catheter is connected to the balloon expansion pressure pump;

[0009] Furthermore, the tip of the puncture needle is configured as a bevel structure;

[0010] Furthermore, the anesthesia needle includes: a needle body and a connector; the connector is detachably arranged at the end of the needle body;

[0011] Furthermore, a marking line is provided on the outside of the puncture needle; a marking line is provided on the outside of the balloon catheter; and a marking line is provided on the outside of the anesthesia needle.

[0012] The beneficial effects of the present invention are:

[0013] The present invention discloses a puncture assembly for trigeminal ganglion balloon compression surgery under local anesthesia. First, by designing the anesthetic needle as a detachable structure and enabling it to be slidably mounted inside the puncture needle, accurate local anesthesia is first performed during the puncture process, and then the same puncture channel is used for subsequent balloon catheter insertion operations. This design not only improves the accuracy of puncture, but also reduces the risk of tissue damage caused by multiple punctures, effectively reducing the patient's pain and the probability of surgical complications.

[0014] Secondly, the balloon fixed at the front end of the balloon catheter and its connection to the balloon expansion pressure pump enable precise control of the balloon's inflation level during surgery to achieve appropriate compression of the trigeminal ganglion. Furthermore, the pressure pump's real-time monitoring of the balloon's internal pressure provides doctors with a crucial reference point, ensuring the safety and effectiveness of the surgical procedure and avoiding nerve damage or other adverse consequences caused by excessive balloon pressure.

[0015] Furthermore, the marking lines on the exterior of the puncture needle, balloon catheter, and anesthesia needle provide intuitive visual references for the surgeon during surgery, helping to more accurately determine puncture depth and catheter position, further enhancing surgical precision. This multifaceted design optimization not only improves surgical efficiency but also provides a safer and more reliable treatment experience for patients, demonstrating its high clinical application value and potential for widespread adoption.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Example 1

[0024] The present invention discloses a puncture assembly for trigeminal ganglion balloon compression under local anesthesia, Figures 1 to 3 In order to achieve the above technical effects, the present invention discloses an anesthesia puncture assembly specifically used for trigeminal ganglion balloon compression surgery, including a puncture needle 1, an anesthesia needle 2, a balloon catheter 3 and a balloon expansion pressure pump 4. The anesthesia needle 2 is designed to be a detachable structure, and can be slidably sleeved inside the puncture needle 1. This design allows the anesthesia needle 2 to be used for precise local anesthesia during the puncture process. After the anesthesia is in place, the puncture needle 1 is inserted along the anesthesia needle 2, which facilitates the subsequent insertion of the balloon catheter 3. At the same time, the balloon catheter 3 also adopts a design that is detachably slidably sleeved inside the puncture needle 1, which not only facilitates the insertion and position adjustment of the balloon catheter 3, but also ensures that it accurately reaches the target area under the guidance of the puncture needle 1.

[0025] A balloon 301 is fixedly mounted at the front end of the balloon catheter 3, a key component for performing the balloon compression procedure. A balloon expansion pressure pump 4 is connected to the balloon catheter 3. Its primary function is to inject contrast agent into the balloon 301 of the balloon catheter 3, enabling clear imaging observation of the position and expansion of the balloon 301 during the procedure. Furthermore, the balloon expansion pressure pump 4 is capable of detecting the internal pressure of the balloon 301. This function is crucial for ensuring the safety and effectiveness of the procedure, as it allows the surgeon to monitor the inflation level of the balloon 301 in real time, preventing unnecessary nerve damage caused by excessive pressure.

[0026] The tip of the puncture needle 1 is designed with a bevel structure, which helps to penetrate the tissue more smoothly during the puncture process, reduce puncture resistance, and improve the accuracy and success rate of the puncture. The anesthesia needle 2 consists of a needle body 202 and a connector 201, wherein the connector 201 is detachably arranged at the end of the needle body 202. This design not only increases the flexibility of the anesthesia needle 2, but also facilitates rapid replacement or adjustment as needed during the operation. In addition, marking lines are set on the outside of the puncture needle 1, the balloon catheter 3 and the anesthesia needle 2. These marking lines play an important reference role during the operation, helping doctors to more accurately judge the puncture depth and the position of the catheter, thereby further improving the accuracy and safety of the operation.

[0027] The working principle and usage process of this device are as follows:

[0028] Before the procedure begins, the doctor prepares the entire assembly, including the puncture needle 1, anesthesia needle 2, balloon catheter 3, and balloon inflation pressure pump 4. The puncture needle 1, serving as the primary guiding tool, features a beveled tip that allows for more precise penetration of the skin and tissue, reducing puncture resistance and ensuring an accurate and stable puncture path.

[0029] In the first step of the procedure, the doctor inserts an anesthetic needle 2 into the patient's body. Using the needle body 202 and connector 201, the doctor precisely injects the local anesthetic around the designated puncture point. Once the anesthetic has taken effect, connector 201 is removed, and puncture needle 1 is inserted along the path of needle body 202. Once needle 1 is in place, needle body 202 is removed, and the balloon catheter 3 is then inserted into puncture needle 1.

[0030] The balloon catheter 3 also utilizes a removable sliding sleeve design, allowing for smooth insertion along the internal channel of the puncture needle 1. The balloon 301, fixed at the front end of the balloon catheter 3, is a key component in achieving the surgical objective. Once the balloon catheter 3 reaches the predetermined location of the trigeminal ganglion, the doctor operates the balloon expansion pressure pump 4 connected to the balloon catheter 3. The pressure pump's primary function is to inject contrast agent into the balloon 301 while simultaneously monitoring the pressure within the balloon 301 in real time. The injection of contrast agent makes the balloon 301 more clearly visible during imaging examinations. Using imaging equipment, the doctor can precisely observe the position and expansion of the balloon 301, ensuring that the balloon 301 accurately compresses the specific area of ​​the trigeminal ganglion. The pressure detection function of the pressure pump provides a crucial safeguard for surgical safety. Based on real-time pressure data, the doctor can precisely control the filling level of the balloon 301, avoiding nerve damage or other complications caused by excessive pressure.

[0031] During the procedure, the marking lines on the exterior of the puncture needle 1, balloon catheter 3, and anesthesia needle 2 also play a crucial role. These markings provide the surgeon with a visual reference, helping them more accurately determine puncture depth and catheter placement, further enhancing surgical precision and safety. The entire procedure is seamless, from puncture and anesthesia to balloon inflation and pressure monitoring. Each step is closely linked and coordinated, ensuring a smooth surgical procedure.
