Description

Technical Field

[0001] This utility model belongs to the field of SMAS fascia lifting technology, specifically relating to a guiding device for SMAS fascia lifting. Background Technology

[0002] SMAS fascia removal surgery is a type of wrinkle removal procedure that allows for specific incision sites to be chosen for wrinkles in different areas of the face. After separating the skin tissue from the SMAS fascia, the SMAS fascia is lifted and fixed backward or upward. Excess skin tissue after tightening is then removed, which helps the skin quickly return to a firm state. It is a type of wrinkle removal surgery that improves skin laxity and sagging.

[0003] For improving facial skin laxity or sagging, the most common method currently is the use of V-shaped thread lifting to tighten the fascia in the sagging areas of the face. V-shaped thread lifting typically involves inserting the thread into the scalp. This is primarily because V-shaped thread lifting uses long threads, which are further divided into suspension and non-suspension types. The suspension type uses a method where one end of the thread is positioned within the scalp to achieve a facial lifting effect, while the non-suspension type only embeds the thread in the face without fixing it to the scalp.

[0004] The main reason for using the V-shaped thread lift, which involves inserting the thread through the scalp, is that it will not damage the skin on the face. Moreover, the incision made through the scalp is relatively inconspicuous, and will not cause scars on the face or affect facial appearance.

[0005] The procedure of inserting large V-line sutures through the scalp mainly uses guide needles to advance the sutures at multiple points on the curved surface of the head, which increases the complexity and surgical risks of puncturing and threading the scalp tissue.

[0006] In view of this, the present invention proposes a guiding device for SMAS fascia lifting. Utility Model Content

[0007] The purpose of this invention is to provide a guiding device for SMAS fascia lifting that can solve the above-mentioned technical problems.

[0008] The specific technical solution adopted by this utility model is as follows:

[0009] This utility model provides a guiding device for SMAS fascia lifting, including a needle body. The needle body has a hollow cavity that extends through both ends. One side of the needle body is integrally provided with a piercing part, and the other side of the needle body has a notch that communicates with the hollow cavity near the end section.

[0010] When using the above-mentioned guiding device for SMAS fascia lifting, the needle body can be bent according to the curvature of the head to fit the curvature of the head. Then, the guide wire on the large V line is passed through the hollow cavity and then blocked by the inclined surface on the plug to guide the protruding concave part. This makes it easy to fix the guide wire to the needle body and then guide the wire to travel.

[0011] Preferably, the hollow cavity is provided with a plug corresponding to the notch.

[0012] Preferably, the needle body and the puncture guide are made of tough medical steel with a diameter of 3 mm, and the total length of the needle body and the puncture guide is between 170 and 190 mm.

[0013] Preferably, the diameter of the hollow cavity is set between 2.2 and 2.4 mm.

[0014] Preferably, the width of the notch is between 2-3 mm.

[0015] Preferably, the plug has a blocking surface on one side that corresponds to the same cross-section as the recess, and the plug has an adhesive portion on its outer periphery that connects to the wall of the hollow cavity.

[0016] Preferably, the other side of the plug is provided with a tapered portion that facilitates insertion into the hollow cavity.

[0017] The beneficial effects are:

[0018] 1. This utility model uses a hollow cavity on the needle body to facilitate bending of the needle body to accommodate the curvature of the head. In this way, the large V-line is fixed to the needle body by the notch, and traction puncture is performed under the scalp tissue to improve the guidance effect and surgical efficiency.

[0019] 2. This utility model allows the guide wire of the connected large V-shaped wire to pass through the hollow cavity and be blocked by the inclined surface of the guide surface, thus facilitating the threading and fixing. Attached Figure Description

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1-3 As shown, a guiding device for SMAS fascia lifting includes a needle body 1, a hollow cavity 3 with both ends passing through it, an piercing part 5 integrally provided on one side of the needle body 1, the piercing part 5 being a constricted cone shape with a blunt end, and a notch 2 communicating with the hollow cavity 3 on the other side of the needle body 1 near the end face.

[0027] As an optional implementation, the hollow cavity 3 is provided with a plug 4 corresponding to the recess 2. The plug 4 is made of medical rubber. This arrangement can seal one side of the recess 2 in the hollow cavity 3, reduce the residue of blood and bacteria in the hollow cavity 3, and improve the cleanliness of the hollow cavity 3.

[0028] See attached document Figure 2 The needle body 1 and the puncture guide 5 are made of tough medical steel with a diameter of 3mm. The total length of the needle body 1 and the puncture guide 5 is between 170-190mm, which makes it easy to bend the tough medical steel needle body 1 according to the curvature of the head, so as to meet the user and increase the range of use.

[0029] Furthermore, the diameter of the hollow cavity 3 is set between 2.2 and 2.4 mm.

[0030] Furthermore, the width of the notch 2 is set between 2-3mm, and the shape of the notch 2 is set as an inward concave shape cut by a cylinder perpendicular to the needle body 1.

[0031] See attached document Figure 3 The plug 4 has a guide surface 41 on one side that corresponds to the same cut surface as the notch 2. The guide surface 41 is in contact with the inner wall of the hollow cavity 3, which facilitates the upward oblique guidance of the wire inserted into the hollow cavity 3, thus achieving the effect of easy wire threading and fixing. The plug 4 has an adhesive part 42 on its outer periphery that is connected to the wall of the hollow cavity 3. The adhesive part 42 is connected to the inner wall of the hollow cavity 3 using medical adhesive.

[0032] Furthermore, the other side of the plug 4 is provided with a conical part 43 that facilitates insertion into the hollow cavity 3, so that the plug 4 can be easily inserted into the hollow cavity 3 through the conical part 43, thus making it convenient to install the plug 4.

[0033] With the above structure, when in use, the needle body 1 can be bent according to the curved surface of the head to fit the curved surface of the head. Then, the guide wire on the large V line is passed through the hollow cavity 3 and then blocked by the inclined surface on the plug 4 to guide the protruding recess 2. This makes it easy to fix the guide wire to the needle body 1 and then guide the wire to run.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
