Description

Technical Field

[0001] The utility model relates to the field of implant prostheses for plastic surgery, in particular to a nose tip and columella supporting prosthesis trial mold component. Background Art

[0002] Rhinoplasty surgery requires the implantation of a columella support prosthesis. The support prosthesis needs to be of a suitable height. If the height is too high, it may cause excessive tension on the skin of the columella and the nose tip, which may easily lead to skin necrosis and contracture of the skin and soft tissue. If the support prosthesis is not high enough, the rhinoplasty effect will be lacking. Therefore, during the operation, the surgeon often needs to repeatedly and gradually shorten the height of the prosthesis, and repeatedly try to put it into the implantation site, and judge the appropriate height of the prosthesis by the tension of the columella skin. This process is more cumbersome, and the prosthesis is easily contaminated, and the prosthesis is also easily damaged by excessive carving, resulting in waste. In addition, the technical cost of electronic scanning judgment is relatively high. Therefore, the art has been seeking a low-cost, simple and easy method that can avoid the above defects. Utility Model Content

[0003] The purpose of the utility model is to provide a nose tip and columella support prosthesis trial mold component, which can be used to try to put it into the implantation site to obtain the suitable height and shape of the prosthesis to be implanted, thereby avoiding the above-mentioned defects.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a nose tip and columella support prosthesis trial mold assembly, which includes: a plurality of nose tip and columella support prosthesis trial molds; each of the nose tip and columella support prosthesis trial molds includes a nose tip support structure, a columella main structure and a support foot, wherein the nose tip support structure and the support foot are respectively located at two ends of the columella main structure; wherein the plurality of nose tip and columella support prosthesis trial molds have different height specifications.

[0005] Preferably, the lengths of the columella main body structures of the multiple nose tip and columella support prosthesis trial molds are different.

[0006] Preferably, the trial models of nose tip and columella support prosthesis have height specifications of 22mm, 26mm, 30mm, 34mm and 38mm respectively.

[0008] Preferably, each nose tip and columella support prosthesis trial mold also has a mark on the columella main structure to indicate the corresponding height specification.

[0009] Preferably, each nose tip and columella support prosthesis trial mold is an integrated structure.

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a front view schematic diagram of a nose tip and columella support prosthesis trial mold according to the first embodiment of the utility model;

[0012] Figure 2 It is a side view schematic diagram of the nose tip and columella support prosthesis trial mold of the first embodiment of the utility model. DETAILED DESCRIPTION

[0013] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part embodiment of the utility model, not all embodiments.

[0014] like Figure 1 and Figure 2 FIG. 1 is a schematic diagram of a nose tip and columella support prosthesis trial mold 1 (hereinafter referred to as the prosthesis trial mold) in the nose tip and columella support prosthesis trial mold assembly of the first embodiment of the utility model, wherein Figure 1 This is the front view of the structure. Figure 2 Each prosthesis trial mold 1 comprises a nose tip support structure 11, a nose columella main structure 12 and a support foot 13, and the nose tip support structure 11 and the support foot 13 are respectively located at two ends of the nose columella main structure 12.

[0015] The nose tip support structure 11 is an arc surface, and the columella main structure 12 extends from the nose tip support structure 11 to the support foot 13, and the cross-sectional size gradually increases to provide sufficient support force. The support foot 13 is Y-shaped and is used to be fixed on the surface of the maxillary nasal spine.

[0016] The multiple prosthesis trial molds 1 have multiple different height specifications. The length of the columella main structure 12 in each prosthesis trial mold 1 may be different, while the nose tip support structure 11 and the support leg 13 of the prosthesis trial mold 1 are consistent in size, which is convenient for rapid prototyping and batch processing of the prosthesis trial mold 1. In other embodiments, the nose tip support structure 11 and the support leg 13 of the prosthesis trial mold 1 increase or decrease in the same direction as the length of the columella main structure 12 is different. Preferably, the recommended height specifications of the prosthesis trial mold 1 include: 22mm, 26mm, 30mm, 34mm, 38mm. In a preferred embodiment, the height specifications of the prosthesis trial mold 1 can be further refined into 22mm, 24mm, 26mm, 28mm, 30mm, 32mm, 34mm, 38mm, 40mm. Preferably, multiple prosthesis trial molds 1 with a height specification that is used more frequently can be prepared in the nose tip and columella support prosthesis trial mold assembly. In other words, if the 30mm prosthesis trial mold 1 is used more frequently, the set of prosthesis trial mold assembly will include multiple prosthesis trial molds 1 with a height specification of 30mm.

[0017] In a preferred embodiment, each nose tip and columella support prosthesis trial mold 1 also has a mark on the columella main structure 12 or the nose tip support structure 11 (such as Figure 1 and Figure 2 22mm as shown) to indicate the corresponding height specification.

[0018] Each prosthesis trial mold 1 is an integrated structure, and the material used can be, for example, artificial materials such as porous polyethylene, silicone rubber, and combinations thereof, or can be autologous rib cartilage, allogeneic cartilage, and the like.

[0019] During the operation, the surgeon opens the nose with an open incision and separates the nasal septum cartilage membrane. The doctor can select a prosthesis trial mold 1 from the prosthesis trial mold assembly and try to insert it into the nose. By observing the tension of the skin of the columella and the height specification of the corresponding prosthesis trial mold 1, the height specification of the prosthesis to be implanted can be determined. It is also possible to try several prosthesis trial molds 1 to determine the most suitable height specification. After determining the height specification, the prosthesis corresponding to the height specification can be directly selected; the prosthesis of the corresponding height specification can also be directly carved out on artificial materials or autologous costal cartilage and other materials; further, the prosthesis obtained based on the above selection or preliminary processing is further carved. Then the processed prosthesis is placed in the nasal septum area, adjusted in posture, and sutured and fixed. The used prosthesis trial mold 1 needs to be cleaned and disinfected after use to facilitate cross infection.

[0020] In summary, through the application of prosthesis trial mold components, doctors can quickly locate prostheses of corresponding specifications, based on which they can directly perform fine processing to quickly obtain prostheses with suitable shapes, avoiding the use of overly large prostheses and frequent processing that wastes surgical time, and avoiding the waste of prosthetic materials due to excessive carving (especially when the prosthesis is taken from fresh autologous tissue such as rib cartilage). It also avoids contamination caused by multiple carvings and multiple placements of implant sites, which is beneficial to the patient's postoperative repair.

[0021] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any changes and modifications made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
