AI Technical Summary
Traditional hard metal needles are difficult to conform to the morphology of subcutaneous tissue in floating needle therapy, resulting in blunt damage and pain, high risk of complications, and low sweeping efficiency.
A floating needle was designed, comprising a puncture section and a sweeping section. By utilizing the cooperation of a limiting groove and a positioning block, the concealment and exposure of the steel needle can be switched. Combined with a flexible tube section, it can sweep and disperse, reducing tissue damage.
It achieves flexible sweeping, reducing the risk of tissue damage to patients and improving sweeping efficiency and safety.

Abstract
Claims
1. A floating needle comprising a puncture portion including a handpiece, a steel needle fixed to a front end of the handpiece, characterized in that, The puncture unit also includes a limiting tube fixed to the front end of the handheld component and coaxially arranged with the steel needle, the end face of which has a limiting groove; it also includes a sweeping part, which includes a positioning tube and an outer sleeve coaxially fixedly connected to the front end of the positioning tube, the steel needle passing through the positioning tube and being sleeved in the outer sleeve; the tail end of the positioning tube is inserted and pulled into the limiting tube, and a positioning block is fixedly connected to the side of the positioning tube; wherein, the positioning block can switch positions between the limiting groove and the end face of the limiting tube as the puncture unit moves axially and rotates circumferentially, so that the front end of the steel needle is exposed and hidden in the outer sleeve.
2. A floating needle according to claim 1, characterized in that The end face of the limiting tube is provided with several positioning grooves at equal intervals. The depth of the positioning groove is less than that of the limiting groove. The positioning block has a positioning protrusion in the middle of the side facing the handheld part. The positioning protrusion is fitted into the positioning groove. When the positioning protrusion is fitted into the positioning groove, the front end of the steel needle is hidden in the outer sleeve.
3. A floating needle according to claim 2, wherein The positioning groove and positioning protrusion are mutually complementary V-shaped, arc-shaped, or rectangular.
4. A float according to claim 1 or 2, wherein The handheld component has a guide post fixed at its front end. The steel needle passes through the guide post, which is inserted into the positioning tube and can move axially and rotate circumferentially relative to the positioning tube.
5. A floating needle according to claim 1, wherein The external sleeve has at least one flexible section at its front end that can be bent.
6. A floating needle according to claim 1 or 5, characterized in that, The external sleeve also includes a connecting pipe section fixedly connected between the flexible pipe section and the front end of the positioning pipe, wherein the connecting pipe section is a rigid pipe or a flexible pipe.
