Description

Method for detecting carpal tunnel using ultrasonic detection device

The present invention relates to a method for detecting carpal tunnel by using an ultrasonic detection device, and provides a detecting method that students or doctors can quickly detect the carpal tunnel and perform subsequent processing.

Press, whether in nursing or in medicine, injecting drugs is an indispensable knowledge, and sometimes the injection must be assisted by an instrument to successfully display the injection location, and then prescribe the right medicine to the lesion.

In the treatment or teaching of carpal tunnel syndrome, the teaching manual instructs the students to use the injection needle to inject at the position of the carpal tunnel; as shown in Figure 1, the position of the carpal tunnel A happens to have multiple nerves B, wrist ligaments C, Tendon D, carpal bone E, and artery F converge. If you are not careful, nerve B or tendon D will be stabbed, causing pain to the patient. Carpal bone E will hinder the injection. Therefore, carpal tunnel A is not searched with the help of instruments. Giving injections is quite difficult and quite dangerous.

As shown in Figure 1 in the appendix, if the injection is taken from the side of the ulnar artery, it is easy to let the injection needle stick to the ulnar artery, which may cause the risk of finger ischemia (fingers ischemia); as shown in Figure 2 in the appendix, If the needle is inserted from the radial side, in order to avoid the obstruction of the scaphoid tubercle, the needle must be inserted from the wrist joint, and the radial artery must be avoided first and the needle must be inserted above it; then the radial artery must be avoided. Continuing needle insertion below the distal FCR tendon is difficult to reach the carpal tunnel.

In view of this, ultrasonic detection devices are generally used to measure the wrist in teaching and clinical practice. The location of the tunnel, but the patient will move during the detection process, and the size of the upper carpal tunnel is probably as fine as a grain of rice, which also causes many medical students to be inaccurate in learning and operation, and have misjudgments or Incorrect detection position.

How to correctly teach students or practitioners to find the correct position of the carpal tunnel, and make follow-up judgment and treatment based on the images measured by the ultrasonic detection device, is the purpose of many teaching and medical institutions that have been trying to improve and research.

The main purpose of the present invention is to provide a method for detecting carpal tunnel using an ultrasonic detection device. The probe of the ultrasonic detection device is used to match the posture of a palm, so that the probe can accurately detect the position of the tunnel joint.

The secondary purpose of the present invention is to provide a method for detecting carpal tunnel by using an ultrasonic detection device. Through the technology of the present invention, the position and image of the carpal tunnel can be accurately displayed, so as to assist physicians in the treatment of carpal tunnel syndrome, and to avoid injection contacting blood vessels and nerves or tendons for safety purposes.

Detection methods that can achieve the above purpose include:

Step 1: Lay the palm on a flat surface, with the palm facing up, and naturally straighten and open the fingers to form a "5" shape;

Step 2: Set a mark (Feng Chu point) about 0.5 cm above the Distal wrist crease (that is, at the bottom of the palm-print lifeline);

Step 3: Cooperate with a probe unit of an ultrasonic detection device and set it on the short axis (0-180 degree axis) of the wrist joint of the subject to be tested, and then slightly rotate the probe unit close to the thumb side to let the probe unit Rotate to the direction of the index finger, and the axial direction of the probe unit is exactly the same as that of the index finger and the index finger. recorded on the same axis;

Step 4: Cooperating with the ultrasonic detection device, the probe unit can obtain an image of the carpal tunnel section of the palm on a display of the ultrasonic detection device.

In the embodiment of the present invention, in step 2, the position of the crease is just at the large mausoleum.

In the embodiment of the present invention, in step 3, when searching for the right wrist tunnel image, the middle finger of the right hand is 90 degrees, the probe unit is rotated to the right, and the angle between the middle finger and the probe unit is -20~-25 degrees, in other words the probe unit is positioned at about 70 degrees.

In the embodiment of the present invention, in step 3, when searching for the left wrist tunnel image, the left finger is 90 degrees, the probe unit is rotated to the left, and the angle between the middle finger and the probe unit is 20-25 degrees, in other words That is, the probe unit is located at a position of 110 degrees.

In the embodiment of the present invention, in step 3, the short axis is kept parallel to the image of the display.

Through the above description, the detection method of the present invention has the following advantages:

1. The position of the carpal tunnel can be displayed correctly compared to the method without the use of detection instruments.

2. The detection method of the present invention is accurate and efficient, correctly guides students and doctors to find the position of the carpal tunnel correctly, and avoids the purposeless search of the position of the carpal tunnel by the probe on the palm.

3. Further, the detection method of the present invention can cooperate with the carpal tunnel treatment method, and inject steroids and other drugs into the carpal tunnel to remove the lesions.

4. Through the technology of the present invention, medical students can quickly find the location of the carpal tunnel and further perform simulated injection, which can provide students with clinical experience in the future.

5. Through the technology of the present invention, in addition to providing a rehabilitative doctor as a diagnosis basis, further traditional Chinese medicine can also cooperate with the technology of the present invention to avoid acupuncture needles from hurting parts other than the carpal tunnel in acupuncture treatment.

6. In addition, during the detection process, a thick towel can be laid under the user's wrist, so that the wrist joint can be fully stretched.

As shown in FIG. 2 to FIG. 5 , the present invention is a method for detecting carpal tunnel using an ultrasonic detection device, and the steps include:

Step 1: As shown in Figures 2 and 3, place the palm 1 on a flat surface with the palm facing up, and naturally straighten and open the fingers to form a "5" shape, in order to have better comfort To allow the user's wrist to stretch, a thick towel can be placed under the wrist.

Step 2: As shown in Figure 2, Figure 4, and Figure 3 in the appendix, set a mark 12 (that is, at the top of the Distal wrist crease) 11 (that is, at the bottom of the lifeline of the palm) 0.5 cm above the Attachment Figure 3 for the location of the blue dots). If the crease position 11 is not clear, the thumb can be moved slightly towards the palm side to produce obvious crease marks; and in terms of acupuncture points in traditional Chinese medicine, the position of the crease position 11 just falls on the Daling acupoint.

Step 3: As shown in Figure 2, Figure 5, and Figure 4 in the attachment, cooperate with a probe unit 21 of an ultrasonic detection device 2 and set it on the short axis (0-180 degree axial direction of the wrist joint of the subject to be tested, the position is in the attachment). 4), then slightly rotate the probe unit 21 near the thumb side, so that the probe unit 21 rotates to the direction of the index finger, and the axial direction of the probe unit 21 is just on the same axis L as the index finger, marked on the same axis L .

In the previous steps, if you want to quantify the angle of rotation, the description is as follows: when looking for the right wrist tunnel image, the middle finger of the right hand is 90 degrees, the probe unit 21 is rotated to the right, and the angle between the right middle finger and the probe unit 21 is -20~-25 degrees, in other words, the probe unit 21 is located at about 70 degrees; on the contrary, when looking for the left wrist tunnel image, the left middle finger is 90 degrees, the probe unit 21 is rotated to the left, and the left middle finger is 90 degrees. The included angle with the probe unit 21 is 20-25 degrees, in other words, the probe unit 21 is located at a position of about 110 degrees.

Step 4: As shown in Figure 2 and Figure 5, with the ultrasonic detection device 2, by The probe unit 21 can obtain the image of the carpal tunnel A section of the palm 1 on a display 22 of the ultrasonic detection device 2 . Wherein, in step 3, the short axis is kept parallel to the image of the display 22 . Attached Figure 5 is an ultrasonic schematic diagram of the short-axis exploration of the carpal tunnel by the detection method of the present invention; annexed Figure 6 is an ultrasonic schematic diagram of the detection method of the present invention in the long-axis exploration of the carpal tunnel; and annexed Figure 7 is this Invented a schematic diagram of ultrasound used in carpal tunnel treatment.

As shown in FIG. 2 to FIG. 5 , through the above steps, the position of the carpal tunnel A can be quickly found. For medical students, there is no need to hold the probe 21 on the wrist aimlessly to find the position of the carpal tunnel A. position, and can specifically understand the shape and position of the carpal tunnel A, and then determine the appropriate treatment method through the state displayed on the display 22 .

As shown in FIG. 6 , for a physician who has already practiced, using the technology developed in the present invention, if the physician needs to judge that a drug needs to be applied to the carpal tunnel A, the three detection steps of the present invention can be used to detect the presence of the carpal tunnel A. Depending on the position and the cut plane, the physician naturally injects the drug into the carpal tunnel A from the opposite side of the probe unit 21 (that is, the inner edge of the scaphoid tubercle) through the syringe 3, and supports the carpal tunnel A through the drug to relieve pain.

Further from the technology of FIG. 6, because the detection technology of the present invention can facilitate the physician to perform needle injection, and avoid the situation that the ulnar needle may pierce the radial artery and nerve, and it is not as difficult as the radial needle, And the simple action can solve the lack of conventional detection methods.

As shown in FIG. 7 , students or nursing staff can also perform simulated injection exercises through the aforementioned technique. In this embodiment, the aforementioned palm can be a simulated hand 4 made of rubber, and in the simulated hand 4 There is a soft body of carpal tunnel A and a plurality of sensors serving as nerve B, wrist ligament C, tendon D, carpal bone E, and artery F. When simulating injection, students or nursing staff also follow the steps of the present invention. The simulated hand 4 is placed on a flat surface, so that the folded part 41 of the simulated hand is upward. A mark 42 is set at 0.5 cm, and then the probe 21 is set to the short axis position of the simulated hand 4, and the probe unit 21 is kept parallel to the short axis, and then the probe unit 21 is slightly rotated so that it is on the same axis as the index finger of the simulated hand. On L, the position of the carpal tunnel A can be displayed in cooperation with the ultrasonic detection device 2, and then a simulated needle 5 is used for injection practice. If the carpal tunnel A is inserted correctly, a correct prompt will be generated. B. Wrist ligament C, tendon D, carpal bone E, artery F and other sensors will generate wrong prompts. In this way, it can improve the familiarity of students, medical staff, or residents with injection in the future and the accuracy of needle placement. Confidence, significantly reduce injection time, increase efficiency and reduce patient discomfort from needle insertion.

The detection method of the present invention can be used not only in the treatment of carpal tunnel syndrome, but also in the treatment of acupuncture and moxibustion of traditional Chinese medicine.

To sum up, it is the technical principle immediately applied to the specific implementation of the present invention. If changes are made according to the concept of the present invention, if the function produced by it does not exceed the spirit covered by the description and drawings, it should be Within the scope of the present invention, it is indicated.
