[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figure 1-8 An embodiment of the present invention discloses a negative pressure suction type eye periorbital milia removal device, which is used to realize the integration of disinfection, pricking and negative pressure suction removal of eye affected parts to achieve the purpose of one-time operation. Specifically, the device includes a tube body 1 connected with a suction head 11, wherein the tube body 1 can be set as a transparent tube to facilitate observation of the internal working conditions. Specifically, the suction head 11 described in this embodiment is detachably connected to the tube body 1, and the suction head 11 is set as a silicone head. In addition, in this embodiment, the suction head 11 and the tube body 1 are preferably threadedly connected to facilitate replacement and disassembly and storage. A collection bin 2 is connected to the outside of the tube body 1, and the collection bin 2 is connected to an external negative pressure device. Of course, a structure is also installed at the bottom of the collection bin 2. Through the design of the joint, a convenient connection to an external vacuum pipeline can be achieved;

[0035] Among them, a negative pressure chamber 31 is formed between the collecting bin 2 and the front end of the tube body 1 through the partition 3 on the inner side of the tube body 1, a puncture needle assembly 4 is movably inserted into the inner side of the tube body 1, and a locking assembly 5 for positioning the puncture needle assembly 4 is also provided in the tube body 1.

[0036] Reference Figure 1 , 24. It should be noted that, in order to realize the operation of atomization disinfection in the present embodiment, a liquid storage tank 7 is also fixedly installed on the outer side of the tube body 1, one end of the liquid storage tank 7 is connected to an atomizing nozzle 71, the liquid storage tank 7 is externally connected to a positive pressure device, and disinfectant is stored in the liquid storage tank 7. When positive pressure gas is input, the disinfectant is sprayed out through the atomizing nozzle 71 to achieve disinfection of the patient's affected part. Preferably, a joint for connecting the pipeline should also be provided at the bottom of the liquid storage tank 7 in the present embodiment. In addition, in order to facilitate the observation of the liquid level inside the liquid storage tank 7, the liquid storage tank 7 described in the present invention is preferably a transparent part, so that the liquid level inside can be viewed. Further, in order to realize the addition of disinfectant, a closable liquid filling port should be reserved on the liquid storage tank 7.

[0037] Reference Figure 4 In some embodiments, the puncture needle assembly 4 in the present invention includes a transmission rod 41 passing through the inside of the tube body 1, and a needle 42 is fixed to the end of the transmission rod 41 located on the inner side of the tube body 1. The needle 42 can pass through the suction head 11 along the inside of the tube body 1 to puncture the affected part, and the other end thereof passes through and extends to the outside of the tube body 1.

[0038] Of course, in order to realize convenient operation of the transmission rod 41, the transmission rod 41 and the tube body 1 are circumferentially locked in this embodiment. The circumferential locking method is adopted to prevent the transmission rod 41 from rotating. In a specific embodiment, a guide groove can be opened axially on the outer side of the transmission rod 41, and a protrusion limited in the guide groove is set on the inner side of the tube body 1 to achieve a circumferential locking effect. In addition, a pressing portion 44 is fixedly installed on the outer end surface of the transmission rod 41, and the pressing portion 44 is set as a knob, which can provide a larger holding space while also realizing the stop and limit of the insertion of the transmission rod 41.

[0039] Reference Figure 4 On the basis of the above-mentioned embodiment, in this embodiment, a sealing piston 43 is fixedly sleeved on the outer side of the transmission rod 41, and a hole is provided on the end surface of the partition 3 for the transmission rod 41 to pass through and is plugged and sealed with the sealing piston 43. That is, in this embodiment, by adopting the design of the sealing piston 43, it is possible to achieve sealing with the partition 3 to avoid air leakage at the plug-in point of the transmission rod 41 and the partition 3. During actual operation, due to the sealing design of the partition 3 and the sealing piston 43, the negative pressure stability between the collection bin 2 and the front end of the tube body 1 can be ensured to enhance the adsorption effect on fat particles.

[0040] Reference Figure 4A damping piston 45 is also fixed to the outside of the transmission rod 41, and a return spring 46 is connected between the damping piston 45 and the partition 3. The return spring 46 is used to control the return of the transmission rod 41 after the locking assembly 5 is unlocked. In addition, the design of the damping piston 45 is used to avoid the entire transmission rod 41 from returning too quickly, so as to improve its return stability.

[0041] Reference Figure 5 In some embodiments, the locking assembly 5 in the present invention includes a button 51 inserted into the tube body 1, and a guide portion is fixed inside the tube body 1. The button 51 slides in the guide portion to improve the sliding stability of the button 51. In addition, one end of the button 51 extends into the inside of the tube body 1, and the button 51 is located inside the tube body 1 and is fixedly installed with a locking piece 52. An elastic piece 53 is fixedly connected between the locking piece 52 and the inner side surface of the tube body 1. Preferably, two elastic pieces 53 are provided in this embodiment, and both are configured as springs.

[0042] Reference Figure 5 , 6 On the basis of the above embodiment, the locking member 52 in this embodiment is a plate fixed on the inner side of the button 51, and a locking groove 521 is provided on the plate. A plurality of locking grooves 522 are provided at intervals on the outer side of the transmission rod 41, and the inner side of the locking groove 521 is engaged with the locking groove 522, that is, in the locked state, the locking groove 521 and the locking groove 522 are engaged and positioned. When the transmission rod 41 needs to be moved, the button 51 is pressed, and the button 51 drives the plate to move, so that the locking groove 521 and the locking groove 522 are misaligned, and the transmission rod 41 can be conveniently driven to move.

[0043] Reference Figure 6 Of course, in order to realize the one-way convenient movement control of the transmission rod 41, the slot 522 in this embodiment is a wedge-shaped notch, and the inclined surface of the wedge-shaped notch faces one side of the suction head 11. In this way, when the transmission rod 41 is pressed, the transmission rod 41 can be continuously freely moved through the resistance of the inclined surface, and reversely locked to improve the convenience of controlling the transmission rod 41.

[0044] Reference Figure 3 , 4 In addition, in this embodiment, a one-way component 6 is further provided between the tube body 1 and the collecting bin 2, and the one-way component 6 is conductive toward the inner side of the collecting bin 2. In some embodiments, the one-way component 6 is a plate connected to the opening of the collecting bin 2 through a torsion spring. A resistance block for stopping the partition is provided on the top side of the collecting bin 2 to achieve the effect of one-way rotation of the partition toward the inner side of the collecting bin 2.

[0045] Reference Figure 3 In some embodiments, a through groove is provided on the outer side of the tube body 1 in the present invention, and a connecting portion 12 is formed by extending outward along the through groove, and the one-way component 6 is rotatably connected to the connecting portion 12, wherein a claw portion 13 is provided on the outer side of the connecting portion 12, and a bayonet 21 is provided on the outer side of the collecting bin 2 to be engaged with the claw portion 13. Preferably, two claw portions 13 and two buckles 21 are provided in this embodiment to improve the stability of the engagement, and secondly, the claw portion 13 provides a deformation space by providing two through grooves on the side of the connecting portion 12, and secondly, a resisting inclined surface for resisting the collecting bin 2 should be provided at the bottom of the claw portion 13.

[0046] That is to say, the collection bin 2 described in this embodiment can be easily disassembled, and the design purpose is to disassemble and disinfect the collection bin 2 or directly replace it;

[0047] During the specific operation, first press the claw part 13 on the connecting part 12. The claw part 13 should be symmetrically arranged with two to ensure the stability of the clamping of the collecting bin 2, until the claw part 13 is disengaged from the inside of the clamping port 21 of the collecting bin 2. At this time, the collecting bin 2 can be pulled downward to disassemble it. The operation is simple and convenient.

[0048] It should be noted that in the above-mentioned embodiment, the affected part is first punctured by the needle 42, and then the fat particles are adsorbed by the negative pressure of the collection chamber 2. In order to further improve the convenience of adsorption, it can be designed that when the needle 42 punctures the affected part, the punctured and picked fat particles are directly adsorbed, as described below;

[0049] Reference Figure 4 , 7 8. Preferably, the present invention further comprises a sealing assembly 8 disposed inside the tube body 1;

[0050] The sealing assembly 8 comprises a fixing plate 81 fixed in the tube body 1 and a sealing plate 82 rotatably connected to the fixing plate 81. The end surfaces of the fixing plate 81 and the sealing plate 82 are both provided with a plurality of fan-shaped channels 83.

[0051] When the fan-shaped channel 83 of the fixed plate 81 and the sealing plate 82 are opposite to each other, a conducting channel is formed; when the sealing plate 82 rotates, it can cover the fan-shaped channel on the fixed plate 81, that is, in the normal state of the present invention, the sealing plate 82 is opposite to the fan-shaped channel 83 on the fixed plate 81, and the entire air path is conductive at this time. After the milia papules are punctured with the needle 42, the negative pressure is connected through the collection bin 2 to suck the fat particles. Of course, in the present invention, a torsion spring can also be arranged between the fixed plates 81 to facilitate the resetting of the sealing plate 82 after rotation.

[0052] Reference Figure 8 In addition, based on the above embodiment, the present invention further has a trigger tube 84 fixedly mounted on the side of the sealing piston 43, and a trigger column 85 fixedly mounted on the outer side of the trigger tube 84;

[0053] A sleeve 86 is fixedly mounted on the end surface of the sealing plate 82, and a Z-shaped groove 87 is formed on the end surface of the sleeve 86. The trigger tube 84 is plugged into the inner side of the sleeve 86, and drives the sealing plate 82 to rotate through the trigger column 85 and the Z-shaped groove 87.

[0054] An air hole 88 extending to the interior of the transmission rod 41 is opened at the end of the needle 42, and one end of the air hole 88 passes through the outside of the transmission rod 41. A sealing block 89 is also provided on the outside of the transmission rod 41, and the sealing block 89 is inserted into the hole of the partition 3.

[0055] That is, when the milia is small, it can be directly adsorbed when the needle 42 punctures it. During operation, the transmission rod 41 is first pressed to the maximum movement position. At this time, the sealing piston 43 is separated from the partition 3. At the same time, when the sealing piston 43 moves, the trigger tube 84 on its side will be plugged into the sleeve 86. At this time, the trigger column 85 on the trigger tube 84 slides in the Z-shaped groove 87, thereby driving the entire sleeve 86 to rotate in coordination with the sealing plate 82 until the sealing plate 82 closes the fan-shaped channel 83 on the fixed plate 81;

[0056] Furthermore, when the fan-shaped channel 83 on the fixed plate 81 is closed, the sealing block 89 on the transmission rod 41 is inserted into the hole of the partition 3 to form a seal. At this time, when the collecting bin 2 is connected to the vacuum, the one-way component 6 opens. At the same time, since the sealing block 89 seals the partition 3, the fixed plate 81 and the sealing plate 82 are sealed, a negative pressure space is formed between the fixed plate 81 and the partition 3. When the vacuum is connected, the fat particles can enter the interior of the transmission rod 41 along the air hole 88, and finally be discharged and fall into the interior of the collecting bin 2.

[0057] When working, when the milia are large in size and need to be distributed separately:

[0058] First, connect the collection chamber 2 to a negative pressure device such as a vacuum pump to provide the entire device with a treatment gun suction power, and connect a positive pressure device such as an air pump to the liquid storage chamber 7 to provide the device with atomization spray power;

[0059] Press to start positive pressure, disinfectant is sprayed out through the atomizing nozzle 71, and disinfectant is sprayed on the surgical site. Use a cotton swab to clean the surgical site, press the pressing part 44 on the transmission rod 41, and after the needle 42 moves to the set position, the transmission rod 41 of the needle 42 is locked by the locking assembly 5. When pressed, the sealing piston 43 is separated from the partition 3. At this time, the negative pressure chamber 31 is connected to the back side of the partition 3, and the negative pressure fails;

[0060] Use the extended needle 42 to perform corresponding treatment. After the treatment, press the locking assembly 5 to make the needle 42 rebound. The damping piston 45 makes the rebound process controllable and natural. During the rebound process, the sealing piston 43 is driven to contact the partition 3 to close the negative pressure chamber 31, so that the negative pressure of the negative pressure chamber 31 takes effect, and the required disinfection atomization spraying and negative pressure absorption are performed on the treatment area. The residue flows to the collection bin 2 through the negative pressure chamber 31 and the one-way component 6, thereby completing the entire treatment process.

[0061] When the size is small, consider simultaneous adsorption during puncture:

[0062] Specifically, when the pressing part 44 on the transmission rod 41 is pressed, the needle 42 moves to the maximum moving position, so that the fixed plate 81 and the sealing plate 82 are sealed, and the sealing block 89 seals the partition 3. Therefore, a negative pressure space will be formed between the fixed plate 81 and the partition 3. When the needle 42 pricks the millet papules, the fat particles can enter the interior of the transmission rod 41 along the pores 88, and finally be discharged and fall into the interior of the collection bin 2.

[0063] Secondly, the present invention adopts a replaceable silicone suction head 11, which is suitable for different surgical sites. Of course, the needle 42 and the transmission rod 41 can also be fixed by a threaded connection. By unscrewing the needle 42, different treatment needles and disinfection treatment needles can be replaced.

[0064] In summary, the present invention adopts the design of the needle assembly 4, the collection chamber 2 and the liquid storage chamber 7, which is used to integrate disinfection, pricking and negative pressure suction into one, and can be completed in one operation; and the negative pressure suction can simultaneously remove blood accumulation in the tissue, facilitate operation, and quickly remove fat particles. The overall structural design is simple and reasonable. The integrated treatment device greatly improves the efficiency of medical diagnosis and treatment and the convenience of operation.

[0065] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
