[0002] Skin cysts are sac-like structures formed in the dermis or subcutaneous tissues. The sacs may contain liquid or other substances. They are common skin lesions that can occur anywhere on the body. Most of them appear as localized dermal or subcutaneous papules or nodules that are higher than the skin surface. The traditional treatment method is to puncture the epidermis of the cyst with a medical needle and squeeze it in a circular shape by hand to squeeze out the hard secretions of the cyst. The advantage is that there is no need to perform a large wound treatment through surgery, which saves patients money and postoperative recovery. The disadvantage is that the puncture needle hole is too small, which is easy to be not cleaned properly and residues may lead to secondary recurrence. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0021] This specific embodiment provides a needle device for skin use to solve the technical problem in the prior art that the cystic structure needs to be squeezed by hand, resulting in a large amount of residual liquid, which is easy to cause secondary recurrence.

[0022] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to the solutions required as the utility model described in the claims.

[0023] Reference Figure 1-Figure 3The utility model provides a needle device for skin use, comprising a needle 1, a sleeve 2, and a scoop 3, wherein the needle 1 is inserted into the sleeve 2, and the length of the needle is longer than the length of the sleeve 2, so as to drive the sleeve 2 to be inserted into the patient's skin, that is, like an infusion hose, the needle 1 is used to pierce the skin to form a wound, thereby facilitating the sleeve 2 to be brought into the skin. After the sleeve 2 enters the patient's body, the needle 1 is retracted from the sleeve 2. In order to facilitate people to dig out the hard secretions in the cystic structure, a digging spoon 3 is arranged on the outside of the sleeve 2. One end of the digging spoon 3 is hinged to the sleeve 2, and the other end is connected to the sleeve 2 through an elastic member 4, so that the digging spoon and the sleeve 2 form a certain angle, and the digging spoon 3 brings out the hard secretions. Specifically, when the sleeve 2 enters the patient's skin, due to the pressure of the skin, the elastic member 4 is compressed, so that the digging spoon 3 is close to the sleeve 2, thereby facilitating the digging spoon 3 to enter the patient's skin. After the digging spoon 3 passes through the wound, the elastic member 4 is no longer subject to the pressure of the wound position. The digging spoon 3 rotates around the position of the hinge axis under the action of the pressure of the elastic member 4, so that the digging spoon 3 is away from the hinge One end of the connecting shaft is away from the sleeve 2, and a space for accommodating hard secretions is formed between the sleeve 2 and the scoop 3. After use, the medical staff removes the sleeve 2 from the wound. Since the scoop 3 is opened inside the wound, the cross-sectional area is relatively large. However, the wound at the patient's skin position is elastic. The opened scoop 3 can go out from the elastic wound position, and then take out the hard secretions in the cystic structure. This operation is repeated to completely remove the hard secretions in the cystic structure, which greatly reduces the situation where medical staff squeeze out the hard secretions by hand, reduces the problem of residual hard secretions, and prevents secondary recurrence.

[0024] In this embodiment, in order to conveniently accommodate more hard secretions, a cavity 6 is provided on the side of the scoop 3 close to the sleeve 2, and the cavity 6 is used to accommodate hard secretions with a cystic structure. In this way, during the process of removing hard secretions at one time, medical staff can store more hard secretions in the cavity 6, thereby reducing the number of times the needle 1 is inserted into the skin.

[0025] In this embodiment, in order to facilitate the cannula 2 to enter the patient's skin from the wound, the cannula 2 is configured to be conical, that is, the cross-sectional area of ​​one end of the cannula 2 is relatively small, and the cross-sectional area of ​​the other end is relatively large. The first end of the cannula 2 is the end with a relatively small cross-sectional area, which is used to pierce the patient's skin, and the cross-sectional area of ​​the second end is relatively large, which is convenient for people to hold.

[0026] In this embodiment, in order to prevent the distance between the scoop 3 and the sleeve 2 from becoming larger when the sleeve 2 is removed from the wound, making it inconvenient to remove the scoop 3 from the wound, a fixing rope 5 is provided between the sleeve 2 and the scoop 3. The fixing rope 5 is provided at a section of the scoop 3 away from the sleeve 2. In this way, when the fixing rope 5 is in a taut state, the scoop 3 cannot continue to open and can only be maintained at a certain angle. Since the wound is relatively small, the scoop 3 is prevented from continuing to expand outward.

[0027] In this embodiment, in order to facilitate the scoop 3 to smoothly come out of the wound, the angle formed between the scoop 3 and the sleeve 2 is 30°-60°, which can not only accommodate more hard secretions, but also facilitate coming out of the wound.

[0028] In this embodiment, in order to facilitate the scoop 3 to accommodate more hard secretions and prevent the hard secretions from flowing out from both sides of the scoop 3 when being taken out from the inside to the outside, the scoop 3 is configured to have an arc-shaped cross-section to wrap the sleeve 2. This not only reduces the occupied area, but also can accommodate more hard secretions.

[0029] In this embodiment, in order to facilitate the digging spoon 3 to come out of the wound and dig out more hard secretions at one time, the length of the digging spoon 3 is 2-3 mm, and the length of the digging spoon 3 set on the sleeve 2 is 20-30 mm. The digging spoon 3 is evenly distributed along the circumference of the sleeve 2, and the digging spoon 3 is arranged in 2-6 rows along the extension direction of the sleeve 2. In this way, the digging spoon 3 set on the sleeve 2 can dig out more secretions, thereby reducing the number of times the sleeve 2 pierces the skin.
