Problems solved by technology

[0007] The purpose of the present invention is to provide a negative-pressure hollow needle to solve the above-mentioned problems in the background technology, although it can be simple in structure, easy to operate, safe and convenient to use, and the needle knife does not need to be pulled out and inserted repeatedly during the treatment process. Rotate the required angle to reduce the pain of the patient, but it cannot solve the problem of more bleeding, damage to nerves and blood vessels, damage to surrounding tissues, and increase the pain of the patient

Embodiment 1

[0025] see Figure 1-3 , the present invention provides a technical solution: a negative pressure hollow needle, comprising a hollow rubber ball 1, an intermediate tube 2, a hemispherical block 3, a rubber pad 4, a glass window 5, a needle body 6 and a needle head 7, the needle body 6 One end is fixedly connected with an inclined needle head 7, and a through hole is symmetrically opened on the needle body 6, and a glass window 5 is installed in the through hole of the needle body 6, and a rubber pad 4 is provided on the right side of the glass window, and the The rubber pad is fixedly connected with the outer wall of the needle body 6, the rubber pad 4 is evenly fixedly connected with a hemispherical block 3, the other end of the needle body 6 is provided with a threaded hole, and the needle body 6 is threadedly connected with the intermediate pipe 2 through the threaded hole , the other end of the intermediate pipe 2 and the hollow rubber ball 1.

Embodiment 2

[0027] The negative pressure hollow needle of this embodiment is similar to that of Embodiment 1, the difference is that the needle body 6 and the needle head 7 are both in a hollow state, and when the needle is positioned and inserted, there will be blood return if it encounters a large blood vessel, which avoids the negative pressure in the negative pressure hollow needle. Excessive bleeding occurs during pressure.

Embodiment 3

[0029] A negative pressure hollow needle of this embodiment is similar to that of Embodiment 1, except that the needle body 6 is a cylinder with a diameter ranging from 0.6 mm to 1.2 mm, which is convenient for medical staff to operate and facilitates the operation. Finish.

Abstract

The invention discloses a negative pressure hollow needle in the technical field of medical equipment. The negative pressure hollow needle comprises a hollow rubber ball, a middle tube, hemisphere blocks, rubber pads, glass windows, a needle body and a needle head, wherein one end of the needle body is fixedly connected with the inclined needle head, through holes are symmetrically formed in the needle body, the glass windows are arranged in the through holes of the needle body, the rubber pads are arranged at the right sides of the glass windows, the rubber pads are fixedly connected with theouter wall of the needle body, the rubber pads are fixedly connected with the hemispherical blocks uniformly, the other end of the needle body is provided with a threaded hole, the needle body is inthreaded connection with the middle tube through the threaded hole, and the other end of the middle tube is connected with the hollow rubber ball. The negative pressure hollow needle solves the problem that a patient is easily bled more during surgery, reduces the damage to nerves, blood vessels and surrounding tissues, and alleviates the suffering of patients.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a negative pressure hollow needle. Background technique [0002] The small needle knife is an acupuncture tool made of metal material that looks like a needle and a knife. It was developed on the basis of the ancient nine-needle needle and sharp needle, combined with the scalpel used in modern medicine and surgery. It is the product of the organic combination with soft tissue release surgery. It has a history of more than ten years. It is a trend of further development and is valued by the world. Small needle-knife therapy is a kind of closed release between surgical method and non-surgical therapy. It is formed on the basis of the incision method combined with the acupuncture method. The operation of small needle-knife therapy is characterized by penetrating deep into the treatment site to easily cut the lesion, stripping off harmful tissues, so as to achieve the pu...
