Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a sled-type plum blossom needle device. Background Art
[0002] Plum blossom needle, also known as skin needle or seven-star needle, evolved from the ancient "burr" and "raised thorn" acupuncture methods. It has a history of more than 2,000 years and is a therapy of multiple (cluster) needle shallow acupuncture in acupuncture. The ancients tied 5 or 7 needles into a bundle and stimulated the meridians and acupoints on the surface of the body to achieve the purpose of dredging the meridians, adjusting the yin and yang of the internal organs, and treating diseases. A bundle of 5 needles is shaped like a plum blossom, so it is called a "plum blossom needle", and a bundle of 7 needles is called a "seven-star needle". Because the acupuncture is shallow, it is called "piercing the skin without hurting the flesh", so it is also called a skin needle. By gently tapping the acupoints or local areas, it can relax the muscles and activate blood circulation, dredge the meridians, and achieve the purpose of preventing and curing diseases.
[0003] The use of plum blossom needles includes pressing and tapping. The pressing method is to hold the needle handle with the thumb, middle finger and ring finger, with the end of the needle handle against the back of the palm, and the index finger pressing on the needle handle. When pressing, the wrist moves and the index finger applies pressure. The intensity of the stimulation depends on the pressure of the index finger, which is suitable for hard-handled needles. The tapping method is to pinch the end of the needle handle with the thumb and index finger, vibrate the needle up and down, and use the elasticity of the needle handle to tap the skin. The severity of the stimulation should be based on the weight of the needle and the elasticity of the needle handle, and the strength of the vibration should be controlled. It is suitable for elastic needle handles. Whether it is the pressing method or the tapping method, the operator needs to manually press or tap, and the pressing or tapping actions are repeated mechanically, which will cause certain damage to the operator's hands.
[0004] To solve the above technical problems, a Chinese patent with publication number CN209378047U discloses a handheld electric plum blossom needle, comprising a handle shell, a mounting groove is provided inside the handle shell, a motor is installed inside the mounting groove, a rotating shaft of the motor is fixedly connected to a worm, an inner side wall of the mounting groove is connected to a movable shaft through a bearing, a worm gear and a cam are fixedly connected to the surface of the movable shaft, the upper end of the worm gear is meshedly connected to the worm, a spring sheet is fixedly connected to the right side of the interior of the mounting groove, a lifting slide groove is provided at the left end of the handle shell, a hammer head is slidably sleeved inside the lifting slide groove, an earring is fixedly connected to the upper surface of the hammer head, the left end of the spring sheet passes through the interior of the earring, and a needle is fixedly connected to the lower surface of the hammer head.
[0005] Although the above technical solution can reduce the workload of the operator, the operator may push the plum blossom needle to move while tapping, which may cause the plum blossom needle to scratch the patient's skin. In addition, the operator needs to control the tapping force, depth and frequency of the plum blossom needle according to the patient's needs based on subjective feelings, which requires high skills, experience and physical fitness of the operator, and the degree of productization and automation is very low. At the same time, it cannot be effectively popularized, which hinders the development of appropriate technology of traditional Chinese medicine. Summary of the invention

[0017] The working principle of the technical solution is: rotate the first adjustment seat, because the first fixed seat is threadedly connected to the first adjustment seat, the first adjustment seat will move vertically relative to the first fixed seat, and will also move vertically relative to the plum blossom needle body, so that the depth of the plum blossom needle body extending out of the first adjustment seat can be adjusted, thereby adjusting the tapping depth of the plum blossom needle body. Rotate the third adjustment seat, the third adjustment seat drives the second adjustment seat to rotate, and during the rotation of the second adjustment seat, the bar-shaped through hole will move relative to the connecting rod. Since the circular ring is vertically slidably connected to the driving rod, the connecting rod will move vertically, thereby driving the circular ring to move vertically. Since the circular ring and the lifting block are connected to the elastic member, the movement of the circular ring will compress or stretch the elastic member, thereby changing the elastic force of the elastic member on the lifting block, thereby changing the pressing force of the plum blossom needle body on the skin. The rotation speed of the driving member is adjusted by adjusting the button, thereby adjusting the tapping frequency of the plum blossom needle body. Place the sled board on the patient's skin, and the plum blossom needle body will tap the patient's skin. The driving member drives the driving disc to rotate, and the first protrusion on the driving disc will intermittently drive the lifting block to move, and the lifting block will drive the driving rod, the first fixing seat, the first adjusting seat and the plum blossom needle body to move upward, so that the plum blossom needle body is separated from the patient's skin, and the reset member will be stretched. In this process, the first adjusting seat will drive the four supporting rods to move, and the four supporting rods will drive the four second columns to move upward, so that the second elastic member will be stretched, so that the friction between the sled board and the skin is reduced. After the operator feels the friction reduction, he pushes the mounting seat. The operator pushes the mounting seat to drive the plum blossom needle body forward and slide the sled board on the patient's skin. When the first protrusion does not contact the lifting block, the plum blossom needle body, the driving rod, the first fixing seat and the first adjusting seat will return to their original positions under the elastic force of the second elastic member and the reset member, and move downward together to achieve the plum blossom needle body tapping the patient's skin. In this process, the second elastic member will increase the friction between the sled board and the skin, and the operator will stop pushing the mounting seat after feeling the increase in friction. .
[0018] The beneficial effects of this technical solution are: ① The plum blossom needle body in this technical solution can automatically tap the patient's skin, thereby reducing the workload of the operator. ② This technical solution is equipped with a depth adjustment mechanism, a force adjustment mechanism and a frequency adjustment mechanism, which can reasonably adjust the tapping force, tapping depth and tapping frequency of the plum blossom needle body, so that the device can meet the needs of different patients. ③ The sled mechanism can make the advancement and tapping of the plum blossom needle body alternate, avoiding the situation where the advancement and tapping of the plum blossom needle body are carried out at the same time, resulting in skin scratches. ④ The setting of the needle cover can prevent the plum blossom needle body from pricking the fingers and prevent the fingers from dirtying the plum blossom needle body.

The operator pushes the mounting seat 1, thereby driving the plum blossom needle body 2 forward and making the sled board 21 slide on the patient's skin. When the first protrusion 10 is not in contact with the lifting block 12, the plum blossom needle body 2, the driving rod 13, the first fixing seat 17 and the first adjusting seat 5 will return to their original positions under the elastic force of the second elastic member and the reset member, and move downward together to achieve the tapping of the plum blossom needle body 2 on the patient's skin. In this process, the second elastic member increases the friction between the sled board 21 and the skin, and the operator stops pushing the mounting seat 1 after feeling the increase in friction.
