Description

Novel perforating needle

Technical Field

The utility model relates to the field of medical instruments, in particular to a novel perforating needle.

Background

Acupuncture is a specific disease treatment means in China, and is a medical technology of treating internal diseases by external therapy. Acupuncture and moxibustion treat systemic diseases through the conduction of meridians and acupoints and certain manipulation methods. Acupuncture is a general term of acupuncture and moxibustion, wherein acupuncture is a method of puncturing a needle into a patient's body at a certain angle under the guidance of the theory of traditional Chinese medicine to stimulate the designated acupoints of the human body, thereby achieving the purpose of treating diseases.

The needles have important functions in acupuncture, and needles with different structures and different shapes have different usages and different efficacies in acupuncture. In 1976, professor Zhuhan chapter, Beijing university of traditional Chinese medicine, developed a small needle knife. The small needle knife is similar to the needle in acupuncture, but the sharp end of the small needle knife is provided with a narrow knife edge, so that the double functions of acupuncture and knife cutting can be realized. The small needle knife can stimulate channel qi, dredge qi and blood to achieve the purpose of relieving pain, and can also directly release adhesion and contracture of tissues around the focus and reduce pressure around the tissues, thereby relieving compression of nerves and blood vessels.

In recent years, a new acupuncture method developed by Mr. Gongchangxiang is as follows: after disinfection, the needle is held by hands actively, the skin pricked by the needle is pressed tightly by hands in an auxiliary manner, and the distance from the skin to the bone surface is sensed. The needle point is pressed on the skin of the acupuncture point to quickly penetrate the skin, and the needle inserting angle is quickly adjusted after the skin penetration, so that the needle is perpendicular to the bone surface and is inserted at a constant speed to reach the bone surface. Then the lower part of the needle body is rapidly pinched by the assistant hand, the two hands are matched, the needle body is shaken along the side surface of the needle body to cut the bone surface, the needle is inserted into the bone by about 1mm, and the needle body is pulled out when the needle is felt to be clamped by the bone. The acupuncture method can stimulate acupuncture points and adjacent bone tissues, and has good acupuncture effect.

The needle handle of current little needle sword is mostly flat sheet structure, and the length that the needle handle was inserted to the needle bar is shorter, and the needle bar is relatively poor with the combination effect of needle handle. When the needle is used for acupuncture or cutting a bone surface, the needle bar is easy to shift, so that the perforation effect is poor, the wound is large, and extra pain is brought to a patient.

Patent CN201510744633.8 discloses a small needle knife with a horseshoe-shaped needle handle, which is improved in the degree of combination of the needle handle and the needle bar compared with the conventional structure. However, the needle handle is thin and difficult to be forced during the operation of punching.

Patent CN201620222501.9 discloses a needle knife with a needle handle with abrasive particles, the design of the needle handle can increase the friction force with the hand. The needle shaft is still a flat sheet-like structure, and the position of the needle shaft cannot be effectively stabilized when perforating and cutting bone surfaces.

Patent CN201721486804.2 discloses a needle knife with replaceable needle bar, which can replace needle bars with different needle blade shapes according to different application occasions. But it still can not solve the weak problem of needle handle and needle bar cohesion, the needle sword maneuverability is weak.

Therefore, the market needs a perforation needle with a stable combination of a needle handle and a needle rod and good operability.
