Detailed Description

In order to make the technical field better understand the solution of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings and the detailed description.

The following description includes discussion of the figures with illustrations given by way of example of implementations of embodiments of the invention. The drawings are to be regarded as illustrative in nature, and not as restrictive. As used herein, references to one or more "embodiments" are to be understood as describing a particular feature, structure, and/or characteristic included in at least one implementation of the invention.

In describing the embodiments of the present invention in detail, the cross-sectional view showing the structure of the device is not partially enlarged in general scale for convenience of illustration, and the schematic diagram is only an example, which should not limit the scope of the protection of the present invention. In addition, the three-dimensional dimensions of length, width and depth should be included in the actual fabrication.

In some embodiments, the numerical parameters used in the specification and claims are approximations that may vary depending upon the desired properties of the individual embodiments. In some embodiments, the numerical parameter should take into account the specified significant digits and employ a general digit preserving approach. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the range are approximations, in the specific examples, such numerical values are set forth as precisely as possible within the scope of the application.

The utility model utilizes the front end of the flat needle body to prevent the nasal augmentation material from being injected into the blood vessel by mistake when the nasal augmentation material is injected to the nasal augmentation part. In addition, the bent front end of the needle body can be used for better operation in the nasal cavity. The following description will be given with reference to specific examples.

Fig. 1 and 2 are top and side views of an example injection needle according to an embodiment. The injection needle of the present embodiment includes a needle body 2. The needle body 2 is provided with a hollow channel extending along the needle body 2. The hollow channel extends to the rear end of the needle body 2 for the passage of the augmentation rhinoplasty material. The nasal augmentation material is, for example, auricular cartilage particles. In some implementations, the material injected into the hollow channel can be a mixture containing particles of the soft ear bone and having a certain viscosity.

The front end of the needle body 2 is provided with at least one exposed injection hole 4, and the injection hole 4 is communicated with the hollow channel. In this way, the augmentation material can flow out of the injection hole 4 via the hollow channel in order to enter the augmentation site.

The needle body 2 of the present embodiment has a flat front end. The injection hole 4 may be located, for example, on the broad face of the front end. The flat front end can effectively prevent the front end of the needle body 2 from mistakenly puncturing the blood vessel when the injection needle of the embodiment is used for injecting the nose humping material to the nose humping part, so that the nose humping material is mistakenly injected into the blood vessel. Moreover, the flat front end has a sharp cutting surface, so that the injection can be achieved by cutting through the superficial tissues. In addition, the operator can use the flat front end to peel off or tidy the superficial tissues of the nose augmentation part, so as to obtain better injection environment and be difficult to injure blood vessels.

In some embodiments, the injection needle may further comprise a detachable joint 3. The joint 3 is attached to the rear end of the needle body 2. The syringe can be configured by assembling the injection needle of the present embodiment with another general-purpose syringe component via the joint 3.

In some embodiments, the bore diameter of the hollow channel and the size of the injection hole 4 may be designed according to the material of the hump nose to be injected (such as particle size, viscosity, etc.), enabling injection.

An example injection needle according to another embodiment is shown below.

Fig. 3 is a side view of an exemplary injection needle according to another embodiment. The injection needle of the present embodiment, similar to the injection needle shown in fig. 1 and 2, includes a needle body 2, and a hollow channel (not shown) is provided in the needle body 2 and extends along the needle body 2. The hollow channel extends to the rear end of the needle body 2 for the passage of the augmentation rhinoplasty material. The front end of the needle body 2 is provided with at least one exposed injection hole 4, and the injection hole 4 is communicated with the hollow channel.

Similarly, the front end of the needle body 2 of the present embodiment is flat. The injection hole 4 may be located, for example, on the broad face of the front end.

As shown in fig. 3, the injection needle of the present embodiment is different from the injection needles shown in fig. 1 and 2 in that the front end of the needle body 2 is bent at an angle or arc toward the side where the injection hole 4 is provided. The angle or curvature of the bend can be designed to allow the needle to better conform to the shape of the intra-nasal space to more easily reach deep sites without damaging other tissues.

Similarly, the injection needle may further comprise a detachable joint 3. The joint 3 is attached to the rear end of the needle body 2. The syringe can be configured by assembling the injection needle of the present embodiment with another general-purpose syringe component via the joint 3.

The following illustrates a syringe constructed using the injection needles described herein.

Fig. 4 and 5 are top and side views of an example injector, according to an embodiment. The syringe of the present embodiment further comprises, in addition to the injection needle described above, a joint 3 coupled to the rear end of the needle body 2, a barrel 5 coupled to the joint 3, and a pusher 6 located at least partially within the barrel 5. The needle body 2 is engaged with the barrel 5 through the engaging portion 3. The injection hole 4 is connected to the barrel 5 directly or via the joint 3. Thereby, the nose humping material in the cylinder 5 can be pressure-fed to the nose humping site by the pusher 6 through the hollow channel of the needle body 2 and the injection hole 4.

Fig. 6 is a side view of an exemplary syringe according to another embodiment. As shown in fig. 6, the front end of the needle body 2 is bent at a certain angle or arc toward the side where the injection hole 4 is provided. Similarly, the angle or curvature of the bend may be designed to allow the needle to better conform to the shape of the intra-nasal space, thereby allowing easier access to deep sites without damaging other tissues.

The embodiments provided by the present invention have been described in detail above. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the core concepts of the present invention. It should be noted that, for a person skilled in the art, without departing from the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of the claims of the present invention.
