Problems solved by technology

Using the existing sharp needle to break the skin and open the hole, it is often difficult to find the opened hole later, which reduces the accuracy of the operation
If the opening cannot be found smoothly, a sharp needle is still required for further puncture
In addition, the needle seat of the existing sharp needle is usually conical, and it is easy to slip off and roll off when taking or placing it, causing contamination of the needle tube or failure of puncture
Therefore, the use of existing sharp needles to break the skin and open holes not only makes the operator laborious and time-consuming, but also makes the beauty seeker feel uncomfortable, and also reduces the safety of blunt needle injections

Embodiment 1

[0038] see Figure 1 to Figure 7 , a disposable skin breaking guide needle, comprising a needle tube 1 , a needle holder 2 and a protective sheath 3 .

[0039] The needle tube 1 is composed of the end section 103 of the needle tube, the middle section 102 of the needle tube and the cutting edge 100 which are connected in sequence from front to back. 102 or the front end of the needle tube end section 103. When the needle tube groove 4 ends at the front end 1021 of the needle tube middle section 102, no groove is provided on the needle tube end section 103; groove.

[0040] The needle holder 2 includes a left wing 21, a V-shaped central section 22 and a right wing 23 which are connected successively from left to right. The rear part of the V-shaped central section 22 is a V-shaped tip 201 whose top face is inclined backward and downward; the V-shaped central section The upper surface of the groove bottom of section 22 is longitudinally provided with a needle tube locking gro...

Embodiment 2

[0047] see Figure 8 to Figure 12 , a disposable skin-breaking guide needle, similar to the structure of Embodiment 1, the difference is that: the needle tube 1 is fixed to the V-shaped central section 22 of the needle base 2 by bonding, and the needle tube 1 is fixed to the V-shaped portion of the needle base 2 The length (i.e. the front part of the needle tube end section 103 and the needle tube middle section 102) L23' on the type central section 22 is 10.0mm (see Figure 10 ). The outer diameter D' of needle tube 1 (see Figure 11b ) is 1.3mm, the total length L' is 35mm, and the length L4' of the groove 4 of the needle tube (see Figure 11c ) accounts for 88% of the total length L' of the needle tube. Along the radial section of the needle tube 1, the depth H' of the needle tube groove 4 is 50% of the needle tube diameter D'.

[0048] The disposable skin breaking guide needle of the present invention, when in use, because the needle tube groove (the needle passage of ...

Abstract

The invention discloses a disposable skin-breaking guiding needle. The disposable skin-breaking guiding needle comprises a needle tube, a needle seat and a protecting cover, wherein the needle tube consists of a needle tube tail section, a needle tube middle section and a needle tube cutting edge which sequentially communicate with one another from front to back; a needle tube groove is formed inthe needle tube and is formed from the needle tube cutting edge to the front end surface of the needle tube middle section or the needle tube tail section; the needle seat comprises a left side wing,a V-shaped central section and a right side wing which are sequentially connected from left to right; the front parts of the needle tube tail section and needle tube middle section of the needle tubeare embedded into a needle tube clamping groove of the V-shaped central section, and the needle tube tail section of the needle tube is inserted into a needle tube insertion hole; and a V-shaped tip is clamped into the protecting cover. By virtue of the disposable skin-breaking guiding needle, an operator can conveniently, rapidly and precisely puncture a needling point through a blunt needle, andthe needle seat is convenient to fetch and place, so that the occurring frequencies of slippage, pollution of the needle tube and puncture failure can be greatly reduced, injection of the blunt needle is more comfortable and safe.

Description

technical field [0001] The invention relates to a disposable skin-breaking guide needle, which belongs to the field of medical instruments. Background technique [0002] In the field of medical cosmetology, surgical items commonly include blepharoplasty, rhinoplasty, breast augmentation, and facial remodeling; non-surgical items are divided into injection items (such as hyaluronic acid, botulinum toxin, etc.) and non-injection items (such as phototherapy, freezing, etc.). Among them, injection beauty has been favored by a large number of beauty seekers because of its convenience, speed and no trace. Injection beauty is a cosmetic method that injects biomaterials or synthetic biocompatible materials into the dermis or subcutaneous of the human body to reduce skin wrinkles or shape. Among the injection materials for this type of cosmetic method, hyaluronic acid and autologous fat are currently widely used, second only to botulinum toxin injection. At present, injection need...
