[0040] Embodiment

[0041] Embodiment 1

[0042] A multifunctional needle assembly for skin surgery, as Figures 1 to 4 shown, the multi-needle assembly A includes a suction adapter 2, an injection joint part 4, and an adjusting part 6.

[0043] The suction adapter 2 includes a main body 200 with openings at both ends and a partition wall 26. The main body 200 includes a needle insertion section and a fastening tube section 270. A partition wall 26 is arranged inside the needle insertion section. A needle holder 22 and a suction hole 260 are arranged on the partition wall 26. A needle hole 220 is arranged on the needle holder 22. An air suction port 24 is arranged on the side wall 210 of the needle insertion section.

[0044] Specifically, the suction adapter 2 forms an internal accommodation space W through the side wall 210. A partition wall 26 is arranged inside the internal accommodation space W. A plurality of conical needle holders 22 are arranged on the partition wall 26, and the needle holders 22 are also accommodated inside the internal accommodation space W. Needle holes 220 are arranged inside the needle holders 22 for inserting a plurality of needle members 20 respectively. A plurality of suction holes 260 are also arranged on the partition wall 26. The needle holders 22 and the suction holes 260 are arranged at intervals. Residual drugs or blood (hereinafter referred to as "liquid") on the skin can be sucked through the needle holes 220 and the suction holes 260. During use, the front end opening 202 of the main body 200 is in close contact with the skin, so that a space capable of sucking pressure is formed between the front end opening 202 and the internal partition wall 26 of the main body 200. Therefore, when a suction pressure is formed between the front end opening 202 and the skin, during the surgical process of inserting the needle member 20 into the skin and injecting drugs, the liquid flowing out will remain inside the front end opening 202 or in the internal space behind the partition wall 26, that is, on the side far from the front end opening 202, and then is sucked out through the suction port 24. Among them, the suction adapter 2 can be cylindrical tubular or rectangular tubular.

[0045] The injection joint part 4 includes an introduction tube body 40, a support plate 42 and a side plate 44. A needle member is arranged on one side of the support plate 42, and a side plate 44 is arranged on the other side of the support plate 42. The side plate 44 is in close contact with the inner peripheral surface of the fastening tube body section 270, and the side of the side plate 44 away from the support plate 42 is connected to the introduction tube body 40. The injection joint part 4 is inserted at one end of the suction adapter 2, and the needle member is inserted into the needle holder 22, and the support plate 42 is adapted to the needle holder 22.

[0046] Specifically, the injection joint part 4 is inserted into the internal accommodation space W from the end of the suction adapter 2 away from the front end opening 202, and can be adapted to the needle holder 22 through the support plate 42, wherein the needle member 20 on the support plate 42 is inserted into the needle holder 22 to complete the injection.

[0047] An adjustment part 6 is arranged on the outer peripheral surface of the fastening tube body section 270. The adjustment part 6 can adjust the length of the needle member 20 protruding in the needle holder 22 to adjust the injection depth of the needle member 20.

[0048] Preferably, in this embodiment, the adjustment part 6 is annular, is connected to the fastening tube body section 270 by thread, and a positioning protrusion is arranged at the end of the adjustment part 6 away from the needle member insertion section, and a positioning groove adapted to the positioning protrusion is arranged on the side plate 44.

[0049] Specifically, a first thread 603 is provided on the inner surface of the adjusting portion 6, and a second thread 272 adapted to the first thread 603 is provided on the outer surface of the fastening pipe body section 270. Moreover, the side plate 44 of the adjusting portion 6 and the injection joint portion 4 are fixedly connected through positioning protrusions and positioning grooves. Therefore, by rotating the adjusting portion 6, the suction adapter 2 can be moved away from or closer to the injection joint portion 4 to achieve the protruding length of the needle member 20 at the front end outlet 202.

[0050] Preferably, a blocking wall 25 is provided between the through hole 240 of the air inlet port 24 and the needle holder 22. Specifically, one end of the blocking wall 25 is connected to the outer surface of the needle holder 22, and the other end is connected to the inner surface of the main body 200, which can block the through hole 24 of the air inlet port 24 from communicating with the internal accommodation space W, thus serving as a pipeline for moving the drug. During operation, the drug is inhaled through the inhalation hole 260, moves along the internal flow path, and is inhaled and discharged through the upper air inlet port 24. Due to the obstruction of the blocking wall 25, direct inhalation around the through hole 240 of the air inlet port 24 is avoided, thereby preventing the liquid from concentrating around the through hole 240.

[0051] Preferably, an inlet 402 is provided on the side of the introducing pipe body 40 away from the side plate 44, and the inlet 402 is connected to the discharge port 110 of the syringe 100. Specifically, the introducing pipe body 40 is connected to the syringe 100 to complete the injection work.

[0052] Preferably, an airtight device 5 is provided at the position of the side plate 44 close to the needle holder 22. The airtight device 5 can be a sealing ring, which is connected to the outer surface of the side plate 44 and also to the inner surface of the fastening pipe body section 270.

[0053] Preferably, as Figure 7 shown, the air inlet port 24 is connected to the suction device T through a suction hose 27. The end of the suction hose 27 is connected to a suction motor 28, and a filter 29 is installed on the suction hose 27. Specifically, the air inlet port 24 protrudes from the outer surface of the suction adapter 2 and communicates with the internal accommodation space W through the through hole 240. The suction device T is connected to the air inlet port 24 of the suction adapter 2 through the suction hose 27. The suction motor 28 can generate negative pressure to complete the suction work, and the filter 29 can filter foreign substances such as drugs. The filtered air is discharged through the drain pipe 30, and finally, the leaked drug during the operation is recovered through the filter 29. When the unfiltered foreign substances in the filter 29 accumulate on one side of the suction motor 28, causing the negative pressure to weaken, at this time, clean water can be sucked into the suction hose 27, and the clean water flows out through the drain pipe 30 to complete the cleaning and restore the normal negative pressure.

[0054] Usage process: First, insert the injection joint part 4 into and connect it to the inside of the aspiration adapter 2. Then, insert the adjustment part 6 through the fastening tube body section 270 of the aspiration adapter 2. The introduction tube body 40 of the injection joint part 4 is connected to the discharge port 110 of the syringe 100 to complete the preparation work. During injection, by rotating the adjustment part 6, the aspiration adapter 2 moves back and forth, so as to finely adjust the protruding length of the needle part 20 relative to the front end opening 202. Inject the drug through the syringe 100. With the aspiration adapter 2 closely attached to the skin, the needle part 20 will protrude and penetrate the skin, so that the drug is injected into the skin from the port of the needle part 20. During the operation, the drug will flow out of the skin again, and at the same time, the drug will remain on the skin in a state of being mixed with blood. In order to remove these liquids, start the aspiration motor 28, so that the aspiration hose 27 connected to the aspiration port 24 generates negative pressure to suck out the excess drug remaining on the skin.

[0055] Embodiment 2

[0056] As Figure 5 And Figure 6 shown, the difference from Embodiment 1 is that the method of adjusting the protruding length of the adjustment needle part 20 relative to the front end outlet 202 in this embodiment is different.

[0057] In this embodiment, the adjustment part 6 is a ring with a baffle plate 64. The injection joint part 4 passes through the baffle plate 64 and is inserted into the aspiration adapter 2, and the injection joint part 4 is threadedly connected to the baffle plate 64.

[0058] Specifically, the adjustment part 6 is inserted through the insertion port 602 on the outer periphery of the fastening tube body section 207 of the aspiration adapter 2. A connection hole 640 is provided on the baffle plate 64. The injection joint part 4 passes through the connection hole 640 and is inserted into the inside of the aspiration adapter 2 to be adapted to the needle holder 22. A third thread 403 is provided on a section of the injection joint part 4 in contact with the connection hole 640, and a fourth thread adapted to the third thread is provided on the surface of the connection hole 640 in contact with the injection joint part 4. Therefore, the injection joint part 4 can be moved back and forth by rotation to realize the protruding length of the needle part 20 relative to the front end outlet 202.
