Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a minimally invasive needle for cervical spine target points. Background Technology

[0002] Cervical spine targeted minimally invasive acupuncture is an advanced modern medical technology specifically designed to treat cervical spine diseases such as cervical disc herniation, cervical spinal stenosis, and bone hyperplasia. During the treatment, doctors use a fine puncture needle to precisely reach the lesion area of ​​the cervical spine. Subsequently, depending on the condition, they can choose to perform precise drug injection to reduce inflammation and pain, radiofrequency ablation to relieve nerve compression, ozone therapy to promote the absorption of local inflammation, or other innovative minimally invasive surgical procedures. With its advantages of minimal trauma, rapid recovery, and fewer complications, cervical spine targeted minimally invasive acupuncture has become the treatment choice for more and more patients with cervical spine diseases. It can not only help patients quickly restore their quality of life, but also largely avoid the risks and inconveniences of traditional open surgery.

[0003] Most existing minimally invasive cervical spine targeting needles, when used, often result in the needle slipping off during use due to the lack of an effective fixation device after the doctor inserts the electrode needle into the needle body. This increases the risk and complexity of the operation. Furthermore, when dealing with patients with diverse lesion sites, it is often necessary to frequently adjust the position of the electrode needle to accurately align with the lesion site. This frequent adjustment not only requires the doctor to move the position of the minimally invasive needle multiple times, but may also exacerbate the patient's discomfort and affect the treatment experience and outcome.

[0004] Therefore, those skilled in the art have provided a minimally invasive needle for cervical spine targeting to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a minimally invasive cervical spine target needle. Through a limiting adjustment mechanism, the electrode needle can not only be limited to prevent it from slipping or falling off, but its position can also be adjusted according to the different treatment locations.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A minimally invasive needle for cervical spine targeting includes a needle body. A limit adjustment mechanism is provided at the upper end of the needle body. The limit adjustment mechanism includes multiple limit grooves, an adjustment block, a reset spring, a limit block, a mounting block, two metal springs, two fixing grooves, and an electrode needle.

[0008] The adjusting block is externally slidably disposed inside the mounting block. Multiple limiting grooves are externally opened on one side of the adjusting block. The limiting block is externally rotatably disposed on one side of the mounting block. One side of the limiting block is snapped into one of the multiple limiting grooves. Two fixing grooves are externally opened at both ends of the mounting block. The lower ends of the two metal springs are fixedly disposed on the upper end of the needle body. The two metal springs are slidably disposed on opposite sides inside the two fixing grooves. The upper end of the electrode needle is fixedly disposed at the lower end of the adjusting block.

[0009] Furthermore, one side of the reset spring is fixedly disposed inside the mounting block on one side, and the other side of the reset spring is fixedly disposed on one side of the limiting block.

[0010] Furthermore, multiple annular scale lines are fixedly provided on the outside of the needle body, and a connecting line is fixedly provided on the upper end of the adjustment block.

[0011] Furthermore, a needle tip is fixedly provided at the lower end of the needle body, and the needle tip is a beveled cutting edge.

[0012] Furthermore, a needle core is provided inside the needle body, and a connecting block is snapped onto the upper end of the needle core.

[0013] This utility model has the following beneficial effects:

[0014] 1. The present invention proposes a minimally invasive needle for cervical spine targeting. When the minimally invasive needle is inserted into the lesion site of the patient, the electrode needle is introduced into the needle body through the adjustment block. At this time, the mounting block will cleverly apply pressure to the metal spring on the needle body, causing it to temporarily contract. As the mounting block continues to slide to the preset position, the metal spring rebounds and then embeds into the fixing groove, forming a lock on the mounting block. This effectively prevents the mounting block and electrode needle from falling off, ensuring safety and stability during the treatment process and improving the treatment effect.

[0015] 2. The cervical spine target minimally invasive needle proposed in this utility model allows the doctor to slide the adjustment block inside the mounting block when the position of the electrode needle needs to be finely adjusted according to the patient's lesion. This causes the limiting block to compress the reset spring, which in turn causes the reset spring to move the limiting block away from the current limiting groove. When the adjustment block reaches the desired position, the reset spring quickly rebounds, pushing the limiting block into the new limiting groove. This achieves precise fixation of the position of the adjustment block and the electrode needle, eliminating the need for the doctor to frequently adjust the position of the entire needle body. This not only simplifies the treatment process and improves the convenience of operation but also reduces the patient's discomfort during treatment. Attached Figure Description

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the utility model:

[0025] A minimally invasive cervical spine targeting needle includes a needle body 2. A limiting adjustment mechanism 1 is disposed at the upper end of the needle body 2. The limiting adjustment mechanism 1 includes multiple limiting grooves 101, an adjusting block 102, a return spring 103, a limiting block 104, a mounting block 105, two metal springs 106, two fixing grooves 107, and an electrode needle 108. The adjusting block 102 is slidably disposed outside the mounting block 105. The multiple limiting grooves 101 are formed on one side of the adjusting block 102. The limiting block 104 is rotatably disposed on one side of the mounting block 105. One side of block 104 is snapped into one of the multiple limiting grooves 101. One side of the reset spring 103 is fixedly installed inside the mounting block 105 on one side. The other side of the reset spring 103 is fixedly installed on one side of the limiting block 104. Two fixing grooves 107 are respectively opened on the outside of the mounting block 105 at both ends. The lower ends of two metal springs 106 are fixedly installed on the upper end of the needle body 2. The two metal springs 106 are slidably installed in the two fixing grooves 107 on opposite sides. The upper end of the electrode needle 108 is fixedly installed on the lower end of the adjusting block 102.

[0026] Specifically, before performing minimally invasive targeted treatment on the cervical spine, the doctor will determine the lesion site based on the patient's specific condition, and then mark the target location for treatment using palpation and imaging equipment. At this time, a minimally invasive needle is used to press on the target, causing the needle body 2 to be inserted into the skin through the needle tip 4 until the target depth is reached. By observing the annular scale line 3 on the needle body 2, the doctor can accurately judge and control the insertion depth of the needle tip 4 to ensure the precision of the treatment. When the needle tip 4 reaches the appropriate position, the electrode needle 108 is inserted into the needle body 2 through the adjusting block 102. When the electrode needle 108 is inserted into the needle body 2, the mounting block 105 will compress the metal spring 106 on the needle body 2, causing it to contract. When the mounting block 105 moves to the set position, the metal spring 106 rebounds, embedding itself into the mounting block 105. In the fixing grooves 107 at both ends of 05, the mounting block 105 and electrode needle 108 are kept stable and do not move, avoiding any unnecessary sliding or falling off. When the position of electrode needle 108 in the needle body 2 is finely adjusted according to the patient's lesion location, the adjusting block 102 is moved to slide inside the mounting block 105. The movement of the adjusting block 102 will squeeze the limiting block 104, causing it to compress the return spring 103 and separate from the current limiting groove 101. When the adjusting block 102 slides to the desired position, the return spring 103 pushes the limiting block 104 to embed into the new limiting groove 101, thereby limiting the adjusting block 102 and ensuring precise fixation of the position. This eliminates the need for doctors to frequently adjust the position of the entire needle body 2, simplifying the treatment process, improving the convenience of operation and treatment effect, and reducing patient discomfort.

[0027] Reference Figure 4 and Figure 5 Multiple annular scale lines 3 are fixedly set on the outside of the needle body 2. A connecting line 5 is fixedly set on the upper end of the adjusting block 102. A needle head 4 is fixedly set on the lower end of the needle body 2. The needle head 4 is a beveled cutting edge. A needle core 7 is set inside the needle body 2. A connecting block 6 is snapped onto the upper end of the needle core 7.

[0028] Specifically, the annular scale line 3 on the outside of the needle body 2 helps doctors accurately grasp the insertion depth and avoid damage caused by over-insertion. At the same time, the beveled cutting edge design makes it easier for the needle tip 4 to penetrate the patient's skin, reducing patient discomfort. The puncture operation can also be performed with the assistance of the needle core 7. Then, the needle core 7 is pulled out through the connecting block 6, leaving only the needle tip 4. The connecting wire 5 connects to the treatment machine and transmits current to the electrode needle 108, causing the electrode needle 108 to continuously generate a high-frequency radio frequency current. This causes the water molecules around the needle body 2 to oscillate at high frequency and generate heat. The generated heat energy will cause the protruding lesion to coagulate and shrink, relieving the compression of the lesion on the nerve roots around the cervical spine, thereby achieving the treatment purpose and reducing the patient's pain and discomfort.

[0029] Working principle: When using it, the doctor first determines the location of the target point according to the patient's specific condition. By pressing, the needle 4 at the lower end of the needle body 2 can be inserted into the skin. The depth of insertion of the needle 4 is determined by the circular scale line 3. When the needle 4 is inserted into the appropriate position, the needle core 7 inside the needle body 2 is taken out through the connecting block 6. Then, the electrode needle 108 is placed inside the needle body 2. Then, the connecting wire 5 is connected to the treatment machine, and the pain in the target area is cleared by electric heating.

[0030] Secondly, when the electrode needle 108 is inserted into the needle body 2, the two metal springs 106 at the upper end of the needle body 2 will be squeezed by the outside of the mounting block 105, causing the metal springs 106 to contract. When the mounting block 105 moves to the set position, the compression on the metal springs 106 is released, causing the metal springs 106 to rebound and embed into the fixing groove 107, thereby fixing the metal springs 106 to the mounting block 105 and preventing the mounting block 105 from causing the electrode needle 108 to slide or fall off. When the position of the electrode needle 108 inside the needle body 2 is adjusted according to the lesion site, by moving... The adjusting block 102 slides inside the mounting block 105. As the adjusting block 102 moves, the limiting block 104 is squeezed, causing it to compress the return spring 103 and disengage from the current limiting groove 101. When the limiting groove 101 slides to the desired position, the return spring 103 pushes the limiting block 104 into the new limiting groove 101, thereby limiting the adjusting block 102. During the adjustment process, the electrode needle 108 moves with the adjusting block 102, thereby adjusting its position within the needle body 2. This eliminates the need for frequent adjustments to the overall position of the needle body 2, simplifying the operation process.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
