Description

Technical Field

[0001] The present application relates to the field of plastic surgery and cosmetic medical technology, and in particular to a disposable medical ear puncture trocar. Background Art

[0002] Ear piercing is to create a permanent hole in a specific part of the earlobe for wearing earrings, but there is a risk of scarring at the puncture site. Currently, the common methods of ear piercing are as follows:

[0003] The civilian field includes ear stud guns (metal ear studs are installed before operation) and disposable ear piercers (metal ear studs and gun body are integrated). When performing piercing, the operator holds the gun body, aims at the position where the ear hole is to be pierced, pulls the trigger to trigger the gun body to shoot out the metal ear stud, penetrates the earlobe and other parts, and then uses a metal fixing device to fix the metal ear stud at the piercing position. The ear stud gun is a reusable device. Only the metal ear stud is replaced before use. It is not easy to disinfect. In addition, the early wound after the metal ear stud piercing does not heal. The metal ear stud is easy to cause adverse wound reactions or allergic reactions, and there is a risk of puncture failure.

[0004] Furthermore, the medical field includes disposable medical arteriovenous indwelling needles. The needle was originally mainly used for intravenous puncture and infusion, arterial puncture and catheterization in medical diagnosis and treatment operations. The main structure of the needle is a sleeve structure, and a soft sleeve is provided on the outer sleeve of the steel needle core. During the puncture operation, the medical staff holds the needle core with a sleeve to puncture the corresponding part, and then withdraws the needle core, leaving only the soft sleeve on the human body, and medication can be administered through the sleeve. Later, it was gradually applied to ear piercing operations, with a similar principle, that is, puncture is performed in the earlobe area. After puncturing the earlobe, the needle core is withdrawn, and the remaining sleeve is retained at an appropriate length on both sides of the earlobe. After that, it is cut short and retained in the ear hole area. After the ear hole trauma heals, other ear studs are replaced. After the device is successfully punctured, the soft sleeve is prone to displacement and falling off in the ear hole area, and there is a risk of reset, causing secondary pain to the punctured person. Utility Model Content

[0008] By adopting the above technical solution, the trocar is a disposable device, which can reduce adverse wound reactions or allergic reactions compared to traditional metal earrings. The two occluders cooperate with each other to effectively avoid the displacement and falling of the trocar, thereby reducing the risk of secondary resetting of the trocar, and can also alleviate the pain of the punctured person when the trocar is displaced and re-reset. Medical staff can hold the trocar and perform point-to-point operations under direct vision with high operating accuracy.

[0009] Optionally, the occluder is in a truncated cone shape, and the larger bottom surfaces of the two occluders are arranged facing each other.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 This application is described in further detail.

[0030] The present application embodiment discloses a disposable medical ear puncture trocar. Figure 1 The disposable medical ear puncture trocar comprises a main needle handle 1, which comprises a prismatic main operating block 10, which can be held by medical personnel; a semicircular main ear plate 11 is fixedly connected to both sides of the main operating block 10, which can also be held by medical personnel; a cylindrical connecting block 12 is coaxially fixedly connected to one end of the main operating block 10; a plurality of reinforcing strips 13 are fixedly connected between the connecting block 12 and the main operating block 10, and the plurality of reinforcing strips 13 are evenly arranged around the peripheral wall of the connecting block 12 to improve the stability of the connecting block 12.

[0031] Reference Figure 1A sleeve 2 is coaxially fixedly connected to one end of the connecting block 12 away from the main operating block 10. The sleeve 2 is made of soft material and can be made of the same material as that of a medical venous puncture indwelling needle, as long as it is not prone to allergic reactions. The sleeve 2 in this embodiment is 5 cm long, and the puncture end of the sleeve 2 is set as a bevel; a plurality of scale lines 20 are printed on the outer wall of the sleeve 2, and the plurality of scale lines 20 are evenly arranged along the length direction of the sleeve 2, and the distance between two adjacent scale lines 20 can be set to 1 cm, so that it is convenient for medical personnel to cut off the sleeve 2 according to the scale.

[0032] Reference Figure 1 The trocar also includes a secondary needle handle 3, which includes a prismatic secondary operating block 30, and a semicircular secondary ear plate 31 is fixedly connected to both sides of the secondary operating block 30; a steel needle core 4 is coaxially fixedly connected to one end of the secondary operating block 30, and the puncture end of the needle core 4 is set as an inclined surface, and the needle core 4 is movably inserted into the main operating block 10, the connecting block 12 and the sleeve 2; when the needle core 4 needs to be withdrawn, the medical staff can pinch the secondary operating block 30 or the secondary ear plate 31 and pull the secondary needle handle 3 outward to pull the needle core 4 out of the sleeve 2.

[0033] Reference Figure 1 The trocar needle also includes two occluders 5, which are truncated cone-shaped and made of silicone material. The texture of the occluder 5 is moderately soft and hard, has a certain elasticity, fits the human body and is not prone to allergic reactions. To facilitate the installation of the occluder 5, a clearance hole 50 that penetrates the occluder 5 is opened along the central axis of the occluder 5; one of the occluders 5 is fixedly sleeved on the sleeve 2 through the clearance hole 50, and the occluder 5 and the sleeve 2 can be connected in the form of hot melt, and the other occluder 5 is movably sleeved on the sleeve 2. The maximum diameter of the bottom surface of the occluder 5 is 5 mm. The larger bottom surfaces of the two occluders 5 are arranged facing each other, and the two occluders 5 cooperate with each other to clamp on both sides of the earlobe, thereby effectively fixing the sleeve 2.

[0034] The implementation principle of the disposable medical ear puncture trocar needle in the embodiment of the present application is as follows: before puncture, the medical staff communicates with the punctured person, confirms the puncture position, disinfects and marks the mark point. During puncture, the medical staff holds the main needle handle 1, aligns the needle with the puncture point, and applies a little force to penetrate the earlobe until the bottom surface of the fixed occluder 5 fits the earlobe skin; then another movable occluder 5 is sleeved on the sleeve 2, and the occluder 5 is pushed forward to make its bottom surface fit the earlobe skin. At this time, the two occluders 5 are clamped on both sides of the earlobe.

[0035] Then, the secondary needle handle 3 is pinched to pull the needle core 4 out of the sleeve 2, and the excess sleeve 2 is removed as needed to complete the piercing operation. The disposable medical ear hole puncture trocar needle needs to be strictly disinfected and sterilized before leaving the factory. It is a disposable item to avoid cross infection. Compared with the metal ear stud material, it can effectively reduce the risk of adverse wound reactions or allergic reactions.

[0036] The occluder 5 is truncated cone-shaped as a whole, with a wide bottom surface for contacting the skin to reduce local pressure and relieve the pain of the punctured person. The narrow tip is on the outside, which is convenient for fixing the occluder 5 and reducing its movement. The two occluders 5 cooperate and clamp to effectively prevent the soft cannula 2 from shifting and falling, thereby reducing the risk of resetting the cannula 2 and reducing the pain of the punctured person caused by the displacement or resetting of the cannula 2. At the same time, the trocar is easy to operate. Medical staff hold the trocar and operate point-to-point under direct vision, with high operating accuracy.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
