DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] like Figure 1 A transcranial magnetic stimulation positioning ruler shown in the figure comprises two earplugs 1 for matching with two ears of a person, two rotating shafts respectively arranged on the two earplugs 1 and coaxially arranged with each other, an angle ruler 2 coaxial with the rotating shafts and fixedly connected, a transverse ruler 3 which is U-shaped as a whole, angle scales 4 evenly distributed along the fan-shaped edge of the angle ruler 2 arranged on the surface of the angle ruler 2, vernier scales 5 evenly distributed along the length direction of the transverse ruler 3 arranged on the surface of the transverse ruler 3, a slide rail 6 arranged on the transverse ruler 3 and along the direction of the vernier scale 5, and a slider 7 matched with the slide rail 6; the straight edge of the angle ruler 2 extends in the front-back direction, the two earplugs 1 are located between the two rotating shafts, the left and right ends of the transverse ruler 3 are provided with through holes respectively slidably matched with the two rotating shafts, and the angle ruler 2 is located on the side of the transverse ruler 3 away from the earplugs 1; as shown in FIG. Figure 2 and Figure 3 As shown, the transverse ruler 3 is provided with an angle pointer 8 corresponding to the angle scale 4, and the slider 7 is provided with a cursor pointer 9 corresponding to the cursor scale 5. Through the design of the earplug 1, the patient can wear the transcranial magnetic stimulation positioning ruler on the head to locate the effective magnetic stimulation target. The transverse ruler 3 is U-shaped as a whole, which conforms to the design of ergonomics; through the design of the angle ruler 2 and the transverse ruler 3, after calculating the coordinates of the effective magnetic stimulation target, the transverse ruler 3 can be rotated to rotate the angle pointer 8. When the angle pointer 8 rotates to the target coordinate of the angle ruler 2, it stops, and then the cursor pointer 9 is slid to point to the target coordinate on the transverse ruler 3. At this time, it is only necessary to mark the scalp with a marker pen, and it is convenient for medical personnel to use the existing transcranial magnetic stimulation equipment to stimulate the patient later; the transcranial magnetic stimulation positioning ruler involved in the present invention is simple and practical in design, low in cost, and can bring low-cost and high-practical value medical equipment to a large number of medical institutions.

[0018] Preferably, the transverse ruler 3 includes a U-shaped ruler portion 10 and two first telescopic mechanisms respectively arranged at both ends of the U-shaped ruler portion 10, the first telescopic mechanism includes a first telescopic hole arranged at the end of the U-shaped ruler portion 10 and extending along the length direction of the U-shaped ruler portion 10 and a first telescopic portion 11 matched with the first telescopic hole, and the through hole is arranged on the first telescopic portion 11. Through the design of the first telescopic mechanism, the transcranial magnetic stimulation positioning ruler can be adapted to different head sizes of different patients. If some patients have large heads, the first telescopic portion 11 can be stretched downward to make the transcranial magnetic stimulation positioning ruler adapt to heads of different sizes. Preferably, there is an interference fit between the first telescopic portion 11 and the first telescopic hole, so that when no adjustment is required, the friction force makes the first telescopic portion 11 stationary relative to the U-shaped ruler portion 10.

[0019] Preferably, there are two angle rulers 2, and the two angle rulers 2 are connected to the two rotating shafts respectively. Preferably, two angle rulers 2 are designed, and preferably, two angle pointers 8 are also provided corresponding to the angle rulers 2, so that it is convenient for medical staff to position the position no matter which side they stand on.

[0020] Preferably, a nose positioning mechanism is provided between the two angle rulers 2 for maintaining the straight edge of the angle ruler 2 in a state of extending in the front-to-back direction. The nose positioning mechanism includes a nose tip contact portion 12 and two connecting wires 13. Figure 4 As shown, the nose tip contact part 12 is provided with a concave surface 16 for matching with the nose tip of a person, and the nose tip contact part 12 is respectively connected to the two angle rulers 2 through two connecting lines 13. Through the design of the nose tip positioning mechanism, the straight edge of the angle ruler 2 of the present transcranial magnetic stimulation positioning ruler can be kept in a roughly horizontal direction, thereby increasing the accuracy of the present transcranial magnetic stimulation positioning ruler. The concave surface 16 designed for the nose tip contact part 12 is also convenient for contacting with the nose tip of a human body, which is in line with the ergonomic design.

[0021] Preferably, both angle rulers 2 include an angle ruler body and a second telescopic mechanism, the second telescopic mechanism includes a strip telescopic seat 14 and a second telescopic part 15 provided on the angle ruler body, the strip telescopic seat 14 is arranged parallel to the straight edge of the angle ruler body, the front section of the strip telescopic seat 14 is provided with a second telescopic hole extending in the front-to-back direction, the second telescopic part 15 cooperates with the second telescopic hole, and the nose tip contact part 12 is connected to the two second telescopic parts 15 respectively through two connecting lines 13. The purpose of setting the second telescopic mechanism is also to meet the requirement that the transcranial magnetic stimulation positioning ruler can be suitable for heads of different sizes of different people. When adjustment is required, the adjustment can be achieved by simply extending or pulling the second telescopic part 15 out of the second telescopic hole. Preferably, the second telescopic part 15 has a certain interference fit with the second telescopic hole, so that no additional mechanism is required, and the friction force can make the second telescopic part 15 stationary relative to the strip telescopic seat 14 when the second telescopic part 15 does not need to be adjusted.

[0022] Preferably, the nose tip contact portion 12 and the connecting line 13 are made of silicone. The silicone material is relatively soft, and as a contact with human skin, it not only ensures the comfort of human wearing, but also ensures the applicability of easy wearing.

[0023] The implementation method of this embodiment is that, in the first step, the effective magnetic stimulation target coordinates of the patient are calculated by using data analysis software, such as Matlab software. In the second step, the transcranial magnetic stimulation positioning ruler is worn on the patient's head. Note that the concave surface 16 of the nose tip base part contacts the patient's nose tip. At this time, the first telescopic mechanism and the second telescopic mechanism are adjusted. Specifically, the first telescopic part 11 and the second telescopic part 15 can be adjusted. When the adjustment is completed, the transcranial magnetic stimulation positioning ruler adapts to the size of the patient's head, and the patient should be in a sitting position at this time. At this time, the straight edge of the angle ruler 2 is roughly horizontal. At this time, the horizontal ruler 3 can be rotated first to make the angle pointer 8 correspond to the target scale of the angle scale 4, and then the cursor pointer 9 can be slid to make the cursor pointer 9 correspond to the target scale of the cursor scale 5. At this time, the positioning is completed, and the medical staff can mark the patient's scalp with a marker pen, so as to perform transcranial magnetic stimulation on the patient. Preferably, the slider 7 and the slide rail 6 of this embodiment have a certain interference fit between the rotating shaft and the through hole, so that after the medical staff finds the target scale, no human intervention is required, and the transcranial magnetic stimulation positioning ruler will remain stationary, so that the angle pointer 8 and the cursor pointer 9 both point to the target scale.

[0024] The beneficial effect of this embodiment is that, through the setting of the transverse ruler 3 and the angle ruler 2, the effective position of transcranial magnetic stimulation can be found simply and quickly, thereby shortening the preparation time for patient treatment; at the same time, the transcranial magnetic stimulation positioning ruler has a simple structure and low cost, is suitable for a wide range of medical practitioners, and is easy to use; through the setting of the first telescopic mechanism and the second telescopic mechanism, the transcranial magnetic stimulation positioning ruler can be suitable for patients with different head sizes, further improving the practicality of the present invention, and at the same time, the setting of the nose tip contact part 12 and the connecting line 13 keeps the straight edge of the angle ruler 2 horizontal, thereby improving the accuracy of the transcranial magnetic stimulation positioning ruler.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
