Description

  The present invention relates to an injection container body for cosmetic surgery, which is filled with a gel prosthesis having a cosmetic effect.

  Conventionally, cosmetic surgery has been performed to raise the nose and shape the jaw. In such cosmetic surgery, a method has been used in which a solid prosthesis is formed in advance so that most of the cosmetic surgery conforms to the shape of the surgical site, and this is inserted into an incised surgical site.

  However, with this method, it takes time to mold the prosthesis for each person to be operated, and high technical skill is required to minimize the scar on the surgical site as much as possible. there were. Further, such cosmetic surgery is required to be performed by a simple method and in a shorter time not only by the patient but also by the operator.

  Under such circumstances, a gel-like prosthesis has been developed instead of a solid form, but no proposal has yet been made as to what means can be applied to cosmetic surgery.

  Therefore, an object of the present invention is to provide an injection container body for cosmetic surgery suitable for simple cosmetic surgery using a gel-like prosthesis.

The cosmetic surgery injection container body of the present invention is characterized in that a gel-like prosthesis containing polyacrylamide and a physiological solution is filled in a hermetic injection container.
The hermetic injection container is composed of a syringe for storing a gel prosthesis, a rod for pushing out the gel prosthesis, a needle for injecting the gel prosthesis from the syringe, and a cap for storing the needle. desirable.

  Moreover, it is preferable that the capacity | capacitance of the gel prosthesis with which the said airtight injection container was filled is 1-20 mL.

  According to the injection container body for cosmetic surgery of the present invention, it is not necessary to mold a prosthesis in advance, and the labor for incising the surgical site can be saved, so that more rapid cosmetic surgery can be performed.

  Moreover, since the injection container body for cosmetic surgery in which a required amount of gel prosthesis is filled in advance can be selected according to the shape of the target site of cosmetic surgery, cosmetic surgery can be further simplified. .

  Furthermore, it becomes possible to further reduce the pain and scars of the subject.

Hereinafter, the present invention will be specifically described with reference to the drawings showing examples of the present invention as necessary. In addition, in each drawing, the same code | symbol is turned down and shown about the same site | part.
The injection container body for cosmetic surgery according to the present invention is characterized in that a gel-like prosthesis is filled in a hermetic injection container.

<Gel prosthesis>
The gel prosthesis filled in the hermetic injection container constituting the cosmetic surgery injection container body of the present invention contains polyacrylamide. Since this polyacrylamide has a low molecular weight as compared with the polyacrylamide conventionally used for solid prostheses, the entire prosthesis exhibits a gel-like dosage form.

  The content of such polyacrylamide is usually 3 to 6% by weight, preferably 4 to 5.5% by weight in the gel prosthesis 100% by weight used in the present invention, and the balance is a physiological solution. .

  Specifically, the gel prosthesis is marketed, for example, as Cosmogel (registered trademark: manufactured by Styling Medical Devices Co., Ltd.) containing 5% by weight of polyacrylamide and 95% by weight of physiological solution. The pH value is a suitable value of 5.5 to 7.0, and the handleability is good.

  Since such a gel-like prosthesis has a property of forming a film when inserted into the body, the gel-like prosthesis can be applied to simpler surgery than conventional solid prostheses. It is possible to respond flexibly to the shape of. Moreover, since it has moderate elasticity, it is possible to give a natural shape to the site after surgery.

<Injection container body for cosmetic surgery>
An injection container body for cosmetic surgery according to the present invention is formed by filling the above-mentioned gel prosthesis into a hermetic injection container. The hermetic injection container may have any structure as long as the filled gel-like prosthesis comes into contact with the outside air to prevent alteration and prevent leakage from the inside of the container.

  For example, FIG. 1A shows an overall view of an embodiment of an injection container body for cosmetic surgery according to the present invention. A cosmetic surgery injection container body 1 according to the present invention includes a syringe 2 in which a hermetic injection container accommodates a gel-like prosthesis, a rod 3 that pushes out the gel-like prosthesis, a needle 4 that ejects the gel-like prosthesis from the syringe 2, It consists of a cap 5 of the needle 4 and is filled with a gel-like prosthesis.

  The material of the syringe 2 and the rod 3 is not particularly limited as long as the material has good transparency and chemical resistance, and examples thereof include materials such as polyethylene, polypropylene, polyethylene terephthalate, and polycarbonate. Moreover, the capacity | capacitance of the syringe 2 is although it does not restrict | limit especially because the quantity of the gel-like prosthesis required by the desired surgery site | part fluctuates, Usually, it is about 1-20 mL. Furthermore, a scale may be attached to the outer wall of the syringe 2, and a nodge 10 as shown in FIG. 2 may be provided on the inner wall corresponding to a desired location of the syringe 2. By providing the nodge 10, the rod 3 can be temporarily pressed at the position of the nodge 10, and the capacity of the gel prosthesis ejected from the needle 4 can be limited by a single press against the rod 3. . For example, in the case where the same amount of gel prosthesis is injected at a plurality of locations with respect to the same surgical site, the amount of gel prosthesis that can be injected with a single press if a plurality of nodules 10 are provided at each desired position. Can be automatically restricted, and it is possible to save the trouble of checking the remaining amount of the prosthesis in the syringe 2 every time the gel prosthesis is injected.

Further, the distal end portion 6 of the rod 3 is made of a material having high hermeticity and moderate flexibility, and the periphery of the distal end portion 6 is prevented so that the gel prosthesis accommodated in the syringe 2 does not exude or change in quality. Is in close contact with the syringe 2. Examples of the material of the tip 6 include ethylene propylene rubber, butyl rubber, styrene butadiene rubber, and silicone rubber. Moreover, in order to give moderate lubricity so that operation | movement of the rod 3 may not be inhibited, the fluorine processing may be given to the surface and the grease may be apply | coated.

  Examples of the surgical site using the cosmetic surgery syringe body 1 of the present invention include the cheek, nose, forehead, middle face, jaw, periorbital, chest, and buttocks, and are filled in the syringe 2. The volume of the gel prosthesis is 1 to 5 mL, for example, when correcting facial or small body defects, and 5 to 10 mL when correcting relatively large body defects. When it makes object, it is preferable that it is 5-20 mL. As described above, since the syringe 2 constituting the cosmetic surgery syringe body 1 of the present invention is pre-filled with a required amount of a gel prosthesis corresponding to a desired surgical site, the needle 4 is inserted into the surgical site. Thus, it is only necessary to inject a gel prosthesis, which can reduce surgical pain and minimize scarring. Moreover, not only can cosmetic surgery be performed simply and quickly, but also the generation of surplus prostheses can be suppressed, and the disposal of the syringe body 1 for cosmetic surgery is also simplified.

  The shape of the needle 4 is not particularly limited as long as it has a hollow portion inside and can be easily inserted into a desired surgical site. For example, as shown in FIG. 1 (A), the tip 4 of the needle 4 may be cut obliquely, and as shown in the enlarged view of the needle 4 in FIG. 1 (B). The tip 4 of the needle 4 may have a rounded shape, that is, a so-called cannula shape. The gel prosthesis filled in the syringe 2 is inserted into the body through the hollow portion of the needle 4.

The length l ₁ of the needle 4 is usually about 15 to 200 mm, and the diameter r is about 0.8 mm to 2.5 mm. For example, when the surgical site is a face, l ₁ is 15 to 40 mm, and r is 0.8 mm to
It is preferably 1.2 mm. On the other hand, when the surgical site is a body part, l ₁ is 50 to 120.
mm and r are preferably 1.2 mm to 2.0 mm. When the length and diameter are in the above range, the size of the needle 4 corresponding to the desired surgical site is previously obtained, so that damage to the subcutaneous tissue due to insertion of the needle 4 into an unnecessary site can be prevented. At the same time, a predetermined amount of gel prosthesis corresponding to the surgical site can be smoothly injected into the body.

Further, as shown in FIG. 3A, the needle 4 may be formed with its tip portion curved in advance in the extending direction. Curvature means that when the needle tip is stabbed diagonally, it bends in the forward direction. When the distal end portion of the needle 4 is formed in this way, when the needle 4 is inserted into the surgical site, the curved distal end portion 4a side is turned upward, and the distal end portion is slowly inserted upward from an oblique direction. 4a can be advanced along the epidermis. Thereby, the front-end | tip part 4a does not reach | attain an unnecessary site | part. In this case, it is desirable that the length l ₂ of the needle 4 has a length corresponding to l _1, and the most distal end portion thereof is as shown in the partially enlarged view of the needle 4 in FIG. Alternatively, the shape may be rounded, such as a so-called cannula.

  The material of the needle 4 is usually made of, for example, titanium or a titanium alloy, and may be coated with a fluororesin having a low frictional resistance so that the needle 4 can be easily inserted into the surgical site. Alternatively, it may be a disposable needle 4 made of hard plastic.

As shown in FIG. 4, the needle 4 is sealed by being covered with a sterilized cap 5 so that the gel prosthesis filled in the syringe 2 does not exude or deteriorate. The tip 5a of the cap 5 has such a shape that the tip of the needle 4 is completely intimately contained as shown in the sectional view of the cap 5 in FIG. Holds sex. Such a cap 5 is preferably made of a material having excellent adhesion to the needle 4 and high chemical resistance, and is preferably silicone rubber. Examples of the silicone rubber include methyl silicone rubber, phenyl-methyl silicone rubber, and fluorinated silicone rubber. Immediately before the needle 4 is inserted into the desired surgical site, the cap 5 is removed and used.

  It should be noted that the needle 4 may be detachable from the syringe 2. In this case, the syringe 2 has a shape as shown in FIG. 5 (A), and a gel prosthesis prefilled with the stopper 8 is sealed. The material of the stopper 8 can be the same as that of the cap 5. It is only necessary to remove the stopper 8 immediately before the operation and take out the needle 4 shown in FIG. 5B from the cap 5 and attach it to the syringe 2.

<Cosmetology surgery method>
By using the cosmetic surgery container body of the present invention in which the above-mentioned specific gel prosthesis is filled in a hermetic injection container, a necessary amount of the prosthesis is injected into a desired surgical site and fine adjustment is performed immediately after the injection. However, a desired shape can be formed. Such a shape gives a natural impression and also has a smooth hand feeling.

  As a cosmetic surgery method using the cosmetic surgery container of the present invention, first, surface anesthesia or transmission anesthesia is applied to a desired surgical site. Next, the gel prosthesis is injected into the surgical site using the cosmetic surgery container 1. At this time, when the needle 4 in the cosmetic surgery container body 1 has a shape as shown in FIG. 1 (A) or FIG. 3 (A), the needle 4 is inserted into the surgical site as it is and the syringe 3 is pushed. The gel prosthesis is injected into the body through the hollow portion of the needle 4. Alternatively, when the needle 4 in the cosmetic surgery container body 1 has a shape as shown in FIG. 1B or FIG. 3B, an introduction hole is provided in the surgical site in advance using another injection needle. By inserting the needle 4 into the introduction hole and pushing the syringe 3, the gel prosthesis is injected into the body through the hollow portion of the needle 4. The operation time is usually about 2 to 10 minutes.

  Thus, since it is a cosmetic surgery using the cosmetic surgery container body of the present invention, the gel prosthesis required for the desired surgical site is pre-filled in the cosmetic surgery container body. A cosmetic surgery container can be selected and used, and simple and quick surgery is possible. Moreover, since the predetermined gel-like prosthesis that has been filled is already solidified into a gel shape, it is possible to reduce the sense of foreign body of the operator. Furthermore, such cosmetic surgery does not require the use of a scalpel because it is not a surgical operation that has conventionally been performed using a solid prosthesis. The container body can be easily disposed of.

According to such a cosmetic surgery method, it exhibits excellent effects in nasal surgery, eagle nose correction, nasal bone formation, cheekbone correction, jaw bone formation, gill bone correction, chest correction, buttocks correction, and the like.
In this cosmetic surgery method, after the gel-like prosthesis has once formed a film in the body, the prosthesis can be removed and reinserted again for shape improvement, so that an excellent shape can be easily maintained.

  In addition, it can be carried out in an auxiliary manner in combination with a cosmetic surgery using a conventional solid prosthesis.
