Embodiment 1

[0042] A device capable of expanding nasal tip tissue, used in plastic surgery such as figure 1 -2, it includes a fixed entity 101, an expansion bag 102 and a pipeline 103.

[0043] The fixed entity 101 is a nasal dorsal prosthesis, which can be implanted in the tissue, and the expansion bag 102 is arranged on the front end of the fixed entity 101, for example, by bonding, and the two are formed into one body, and the expansion bag 102 is implanted in the tissue for Expansion of the tip of the nose.

[0044] The pipe 103 is a slot formed in the fixed body 101 , which is a strip-shaped channel along the front and rear length direction of the fixed body 101 .

[0045] The pipeline 103 has an outlet 104 and an injection port 105. The outlet 104 of the pipeline 103 communicates with the expansion bag 102. The given substance injected after the puncture of the fixed entity 101 enters the injection port 105 of the pipeline 103, passes through the pipeline 103 and passes through the...

Embodiment 2

[0052] A device capable of expanding nasal tip tissue, used in plastic surgery such as image 3 -4, including a fixed entity 201, an expansion bag 202 and a pipeline 203.

[0053] The fixed entity 201 is a nasal dorsal prosthesis, which can be implanted in the tissue. The expansion bag 202 is arranged on the front end of the fixed entity 201 in a plug-in assembly, for example. Expand the tip of the nose.

[0054] The pipeline 203 is a stainless steel conduit arranged in the fixed entity 201. An installation groove 204 is provided in the fixed entity 201. The stainless steel conduit is inserted into the installation groove 204 for assembly, wherein the stainless steel conduit is a strip along the front and rear length direction of the fixed entity 201. shaped conduit.

[0055]The pipeline 203 has an outlet 205 and an injection port 206. The outlet 205 of the pipeline 203 communicates with the expansion bag 202, and the injection port 206 of the pipeline 203 is provided on the...

Embodiment 3

[0063] A device capable of expanding nasal tip tissue, such as Figure 5 As shown, the difference between this embodiment and Embodiment 2 is that the injection port 306 in this embodiment is in the shape of a slot, and the injection port 306 is close to the rear end of the pipeline.

Abstract

The invention provides a device capable of expanding nasal tip tissue. The device comprises a fixed entity capable of being implanted into the tissue, an expansion bag capable of being implanted into the tissue and a pipeline, wherein the fixed entity can be punctured and still achieve sealing after being punctured; the expansion bag is located at the front end of the fixed entity; a main body component of the pipeline is arranged in the fixed entity; the pipeline is provided with an outlet and an injection opening; the outlet of the pipeline communicates with the expansion bag; and a given object injected after the fixed entity is punctured enters the injection opening of the pipeline, passes through the pipeline and enters the expansion bag from the outlet of the pipeline. The device provided by the invention can be used for effectively treating short nose deformity and nasal tip defects, which are caused by dysplasia or trauma, and can be used for preventing complications caused by the reason that a nasal prosthesis penetrates through nasal tip skin after a rhinoplasty operation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device capable of expanding nasal tip tissue used in plastic surgery. Background technique [0002] Soft tissue expander, as an advanced treatment method unique to plastic surgery, its principle is to implant the soft tissue expander under the normal skin soft tissue near the lesion, and increase the capacity of the expander by intermittently injecting liquid into the expansion sac, so that it can affect the surface skin soft tissue. Pressure is generated, and the division and proliferation of tissue and epidermal cells and the expansion of cell gaps are caused by the expansion mechanism on the local area, thereby increasing the skin area. After removing the expansion sac, tissue repair and organ reconstruction can be performed with the newly increased skin soft tissue. [0003] In the prior art, there are problems such as incomplete implantation, inconvenie...
