Description

Technical Field

[0001] The invention relates to the technical field of medical assistance, in particular to a navigation-based head needle positioning acupuncture auxiliary device. Background Art

[0002] Scalp acupuncture is a widely used acupuncture treatment method in clinical practice. It can be used to treat a variety of diseases such as stroke, insomnia, dizziness, and headache. At present, the acupoints for scalp acupuncture are mostly located by body surface landmarks, empirical acupoints, and zoned acupoints. Although these acupoint selection methods are simple and fast, due to the influence of various factors such as individual differences in the intracranial cerebral cortex of patients, hair volume, and abnormal skull morphology, the accuracy of acupoint selection is difficult to guarantee, which in turn affects the clinical efficacy and repeatability of clinical trials.

[0003] Magnetic resonance navigation technology mainly uses MR navigation and real-time monitoring systems to display the information of interventional surgical instruments (including position, direction, etc.) in the form of virtual needle shadows on the same MR image simultaneously with the lesions, so that the surgeon can timely understand the positional relationship between the surgical instrument and the target lesion and the signal changes of the target lesion during the treatment process, and timely adjust the surgical instrument insertion point, needle insertion direction and subsequent treatment plan.

[0004] However, there is no report on the combination of cranial magnetic resonance navigation technology and scalp acupuncture in Chinese invention patents. Given the current mature technology, complete conditions, and the widespread application of neuroimaging technology, based on the above, there is an urgent need for a navigation scalp needle positioning acupuncture auxiliary device with a simple structure, easy operation, and the ability to improve scalp acupuncture accuracy and quantify scalp acupuncture parameters. However, there is no report on this new type of navigation scalp needle positioning acupuncture auxiliary device. Summary of the invention

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A head acupuncture positioning and acupuncture assisting device for navigation, comprising a probe body, a needle placement tube and a limiter. The probe body consists of an upper semi-cylindrical body and a lower semi-conical body. Three support rods are connected to the upper half of the probe body, and the support rods are perpendicular to the probe body. A bolt head is provided at the top of the support rod, and an infrared light reflecting head with a bolt hole is further provided on the bolt head, and the infrared light reflecting head is threadedly connected to the support rod; the lower half of the probe body is connected to a needle placement tube, and the needle placement tube is a hollow cylindrical structure, and the diameter of the bottom of the lower half of the probe body is the same as the diameter of the needle placement tube. A rectangular groove is provided on the side of the needle placement tube, and scale lines are correspondingly provided on the groove; a tension adjustment structure composed of three circular fork-shaped metal sheets is connected below the needle placement tube, and the limiter is sleeved on the outside of the tension adjustment structure; the limiter consists of a wrench, a circular retaining piece and a limiting sleeve. The wrench is in a U-shaped structure, with a circular retaining piece connected to the upper end and a limiting sleeve connected to the lower end. The circular retaining piece on the limiter passes through the groove and is located inside the needle placement tube. The limiting sleeve on the limiter is located on the tension adjustment structure, and the limiter slides up and down inside the needle placement tube through the retaining piece and the limiting sleeve.

[0008] In the head acupuncture positioning and acupuncture assisting device for navigation described above, as a preferred solution, the infrared light reflecting heads are arranged in an equilateral triangle on the support frame, parallel to the probe body, and the distance between adjacent two infrared light reflecting heads is 8 - 12 cm.

[0009] In the head acupuncture positioning and acupuncture assisting device for navigation described above, as a preferred solution, the diameter of the circular retaining piece on the limiter is always consistent with the inner diameter of the needle placement tube, and when the circular retaining piece moves to the topmost position inside the needle placement tube, it exactly corresponds to the initial scale on the scale line.

[0010] In the head acupuncture positioning and acupuncture assisting device for navigation described above, as a preferred solution, the limiting sleeve is a hollow frustum-shaped structure, wider at the top and narrower at the bottom.

[0011] In the head acupuncture positioning and acupuncture assisting device for navigation described above, as a preferred solution, the probe body, the needle placement tube and the limiter are all made of metal materials.

Figure 2 Attached is a partial structural diagram of the probe body on the navigation head needle positioning acupuncture auxiliary device of the present invention.

[0028] The present invention mainly solves the problem that the current scalp acupuncture acupoints are mostly based on body surface landmarks, empirical acupoints, and zoned acupoints. However, due to the influence of various factors such as individual differences in the cerebral cortex of patients, hair volume, and abnormal skull morphology, the accuracy of acupoints is difficult to guarantee, which in turn affects the clinical efficacy and clinical trials. Therefore, the cranial magnetic resonance navigation technology and scalp acupuncture are combined to improve the accuracy of scalp acupuncture and quantify the parameters of scalp acupuncture. Therefore, based on the above concept, a navigation scalp acupuncture auxiliary device is provided. The device mainly includes a probe body 1, a needle placement tube 2, and a stopper 3. The probe body 1 is composed of an upper cylindrical body and a lower frustum. The upper half of the probe body 1 is connected to three support rods 4, and the support rods 4 are in the shape of Different positions are set and perpendicular to the probe body 1. The top of the support rod 4 is also provided with a bolt head 5. The bolt head 5 is also provided with an infrared light reflection head 7 with a bolt hole 6. The infrared light reflection head 7 can use MR navigation technology and real-time monitoring system to enable the operator to understand the position relationship between the device and the acupuncture points on the patient's head in real time, present the corresponding positions of the positioning needle and the acupuncture point space, improve the efficiency of acupuncture, and effectively avoid the pain of adjusting the acupuncture direction after the needle is inserted. Through real-time MR technology, the treatment range can be effectively judged and controlled, so that the secondary damage during the treatment process is smaller and the prognosis is better. The infrared light reflection head 7 and the support rod 4 are threadedly connected by bolt screw holes, and the operation is simple and easy to disassemble.

[0029] The lower half of the probe body 1 is connected to a needle placement tube 2. The needle placement tube 2 has a hollow cylindrical structure, and the diameter of the bottom of the lower half of the probe body 1 is the same as the diameter of the needle placement tube 2. A rectangular groove 8 is provided on the side of the needle placement tube 2. The groove 8 is located in the middle of the needle placement tube, penetrates one side of the needle placement tube, and communicates with the inner hole of the needle placement tube. Scale lines 9 are correspondingly provided on the groove 8. Different value ranges can be set on the scale lines 9 as needed to facilitate measuring the precise distance of the head needle insertion and avoid unnecessary harm to the acupuncture patient. A tension adjustment structure 10 composed of three circular fork-shaped metal sheets is connected below the needle placement tube 2, and the limiter 3 is sleeved on the outside of the tension adjustment structure 10. The tension adjustment mechanism 10 is a tension component in the existing device and is very common in daily life, so its structural principle will not be elaborated here. The limiter 3 is composed of a wrench 11, a circular retaining plate 12, and a limiting sleeve 13. The wrench 11 has a U-shaped structure, with a circular retaining plate 12 connected to the upper end and a limiting sleeve 13 connected to the lower end. The circular retaining plate 12 on the limiter passes through the groove and is located inside the needle placement tube 2. The limiting sleeve 13 on the limiter is located on the tension adjustment structure 10, and the limiter 3 slides up and down inside the needle placement tube through the circular retaining plate and the limiting sleeve. The setting of the wrench 11 can facilitate the doctor to push the head needle, provide a supporting effect for the movement of the head needle, improve the comfort of the doctor during use, and at the same time facilitate the doctor to control the force when pushing the needle, avoiding excessive force causing pain to the patient and affecting the needle pushing process of the patient.

[0030] In this embodiment, it is preferred that the infrared light reflecting heads 7 are arranged in an equilateral triangle on the support frame and are parallel to the probe body 1. This setting can make the infrared light reflecting heads 7 all on the same plane to facilitate reading, and the distance between adjacent two infrared light reflecting heads is 8 - 12 cm.

[0031] In this embodiment, it is preferred that the diameter of the circular retaining plate 12 on the limiter is always consistent with the inner diameter of the needle placement tube 2, so as to satisfy the up and down movement of the circular retaining plate 12 inside the needle placement tube. When the circular retaining plate moves to the topmost position inside the needle placement tube, it exactly corresponds to the initial scale of the scale line. When the circular retaining plate moves to the top of the groove on the needle placement tube, the corresponding scale at this time is the 0 scale. When the top of the head needle penetrates into the needle placement tube, the circular retaining plate located inside the needle placement tube can block the head needle from continuing to move upward, and the corresponding original scale at this moment can be used as the initial scale for the head needle to be pushed downward to facilitate controlling the head needle acupuncture depth parameter and improving the accuracy of the head needle acupuncture.

[0032] In this embodiment, the limiting sleeve 13 is preferably a hollow frustum structure, which is wide at the top and narrow at the bottom. The limiting sleeve 13 can wrap around the tension adjustment structure 10. Since the tension adjustment structure 10 is composed of three fork-shaped metal sheets expanding outward, as the limiting sleeve moves upward, the fork-shaped metal sheet inside the limiting sleeve will slowly tighten, and the aperture formed by the three fork-shaped metal sheets will slowly shrink, thereby achieving a fixing effect, avoiding loosening of the probe during acupuncture, stabilizing the angle of head needle acupuncture, and facilitating the smooth progress of acupuncture treatment.

[0033] In this embodiment, the probe body 1, the needle placement tube 2 and the stopper 3 are preferably made of metal material, which is smooth and stable, easy to clean and disinfect, and can be reused.

[0034] The method of using the present invention is as follows: when performing acupuncture on a patient, first place the top of the needle into the needle tube of the device along the tension adjustment structure, and the circular baffle in the needle tube can just block the movement of the head needle. After the head needle reaches the baffle, adjust the limit sleeve on the limiter to force the limit sleeve and the three fork-shaped metal sheets on the tension adjustment structure to be tightly closed, thereby firmly fixing the head needle in the tension adjustment structure to prevent the head needle from moving and causing acupuncture displacement, so as to improve the accuracy of acupuncture; after the head needle is fixed, the MR navigation technology is used to monitor the infrared light reflection head on the probe body, and after the monitoring system detects the accurate acupuncture position, adjust the tightness of the tension adjustment structure, and slowly move downward along the wrench on the limiter, thereby driving the head needle moved down by the baffle to slowly move, and control the depth of the head needle acupuncture according to the scale line on the needle tube; after the acupuncture is completed, clean and disinfect the device for next use.

[0035] It should be noted that: the present invention has a simple structure and is easy to operate. By combining the cranial magnetic resonance navigation technology with scalp acupuncture, the accuracy of scalp acupuncture positioning can be improved. The setting of the infrared light reflection head can utilize the MR navigation technology and the real-time monitoring system to enable the operator to understand the positional relationship between the device and the patient's head acupuncture points in real time, effectively avoiding important tissues such as nerves and blood vessels, thereby reducing the risk of puncture; through real-time MR technology, the treatment range can be effectively judged and controlled, so that the secondary damage during the treatment process is smaller and the prognosis is better; and the setting of the limiter and the tension adjustment structure can adjust the tension effect during the insertion of the scalp acupuncture, and can accurately control the angle and depth parameters of the scalp acupuncture, reduce unnecessary injuries to patients during the acupuncture process, and improve the accuracy of scalp acupuncture.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the principle of the present invention. These improvements and supplements should also be regarded as the scope of protection of the present invention.
