Description

The utility model relates to the field of medicine, in particular to plastic surgery, and can be used during operations to lift the forehead and eyebrows (front lift).

A buccal retractor is known, which is a flattened metal elongated plate, the central part of which is a holder for the surgeon’s hand, and one end is bent to form a support for this hand; at the other end of the flattened plate, bent from the area that is the holder, a working body is organized in in the form of an end part thinning in cross-section and pointed in plan. At the same time, at the top of the end part of the working body there is an open recess with inclined side walls and an arcuate convex section between them to form a bone support zone limited by the inclined walls (according to patent RU165597 class A61C 3/00, publ. 10.27.16).

A surgical retractor with an elongated and wavy body is known, containing at the first end a sigma-shaped retractor for the zygomatic bone, having a central groove and a sharp edge on each side of said central groove. The zygomatic bone retractor passes through the pontic to the second flat end, the flap retractor. The pontic extends in a curvilinear manner to the flap retractor. The surgical retractor may also have an ergonomic cushion to support the doctor's hand (according to patent WO2022195390, class A61C 5/90, A61B 17/02, publ. 09.22.22).

A retractor device is known for breast reconstruction surgery, which provides effective exposure and visibility of the breast pocket and, at the same time, does not violate the integrity of the subcutaneous flap, which leads to a positive result of the breast reconstruction procedure, usually, but not exclusively, performed using a prepectoral (or subcutaneous) cell-free biological matrix (according to patent US11633177, class A61B 17/02, publ. 04/25/23).

A Taylor fulcrum retractor is known, which is a wide, pliable band that can be easily shaped by hand to fit any situation. At the same time, it maintains this shape against forces that may be applied to pull the muscles away from the center of the cut. A fulcrum retractor is especially useful in spine surgery and may have a claw-like spike or spikes that penetrate the surface of the bone within the incision to create an extremely secure fulcrum (per US4610243, class A61B 1/00, publ. 09/09/86) .

The most structurally similar technical solution is a device for transaxillary breast augmentation, including a U-shaped element containing a first part having a first end, a second part having a second end, and a third part extending between the first and second parts opposite the first and second ends. The device also includes a handle protruding from the first end and a corner member protruding from the second end at an oblique angle relative to the longitudinal axis of the second portion. The corner member and at least a portion of the second portion are configured to be positioned through an insertion site in the body to facilitate a surgical procedure, such as guiding a breast implant to a desired location (US20110172496, cl. A61B 1/32, publ. 07/14/11 ).

Each analogue and prototype described above have a narrow range of applications and are used in certain operations. None of the described structures is intended for front lifting operations.

The technical result to be achieved by the proposed utility model is to ensure a non-traumatic expansion of the area of dissection of the patient's skin so that the surgeon can gain access and/or visibility when performing front-lifting operations.

This technical result is achieved by the fact that the retractor for open front lifting is a bent metal strip and is characterized in that the strip has a V-shape, where the bend divides the strip into a working part, at the end of which there is a section bent inward with blunt teeth, and a holder, the end of which is bent inward, forming a hook, while the length of the working part is made in the range from 20 to 80 mm.

In addition, the working part can be made arc-shaped with the apex of the arc directed inward.

In addition, the angle between the working part and the holder can be made in the range from 80° to 60°.

In addition, the length of the inwardly curved section with blunt teeth can be made in the range from 5 to 15 mm.

In addition, the angle between the working part and the area with blunt teeth can be made in the range from 30° to 40°.

The proposed utility model is illustrated by the following drawings, which show:

Fig. 1 – retractor, axonometry;

Fig. 2 – retractor, side view;

Fig. 3 – retractor with a long arcuate working part, axonometry;

Fig. 4 – retractor with a short working part, axonometry;

Fig. 5 – use of a retractor during front lifting surgery.

The retractor for front lifting 1 (Fig. 1) is a bent metal strip 2 of a V-shape. The bend 3 divides the strip 2 into the working part 4 and the holder 5. At the end of the working part 4 there is a section 6 bent inward with blunt teeth 7. The end of the holder is bent inward, forming a hook 8.

The length A of the working part 4 (Fig. 2) is selected from the range from 25 to 80 mm depending on the stage of the operation, the individual characteristics of the patient and the convenience of each surgeon.

The standard retractor (Fig. 1) has a length A of the working part of 65±5 mm and is suitable for working with the foreheads of most patients in the late stages of tissue detachment and at the time of fixing the eyebrows (working with a ligature).

A retractor with a long arcuate working part (Fig. 3) has a working part length L of 75±5 mm. It is used to work with male forehead types (high or with receding hairlines), when the surgical approach is more distant from the eyebrow. That is why it has a maximum length and the working part is made arched with the apex 9 of the arc directed inward to repeat the shape of the frontal tubercle.

A retractor with a short working part (Fig. 4) has a working part length A of 30±5 mm. It is used when working with any type of forehead, but only at the initial stage of the operation (a recess no further than 30 mm). At the initial stage of the operation, a standard retractor, due to the large angle of attack in relation to the tissues, may slip out and not provide reliable retention of detached tissues. This will require increased attention from the surgeon or his assistant.

The angle α between the working part 4 and the holder 5 is in the range from 80° to 60°, which, when retracting the skin, will ensure uniform impact of the working part on the skin from the inside and prevent the retractor from slipping out.

It is advisable to make the inwardly curved section 6 with blunted teeth 7 with a length B in the range from 5 to 15 mm and at an angle β to the working part 4 in the range from 30° to 40°. These parameters, as well as the implementation of blunted teeth 7 (with moderate sharpening sharpness), provide reliable fixation of the detached flap of skin, but do not cause its perforation (puncture).

Application.

The described retractor is used only for open (not endoscopic) lifting (lifting) of ptotic (sagging) eyebrows in men and women. The retractor fully satisfies the technique of this operation, reducing the time of its implementation and, accordingly, the time of anesthesia and health risks and improving the quality of the result, due to less trauma, thanks to an improved overview of the surgical field and ease of access with a surgical instrument.

During the operation, surgical access is made through the incision 10 (Fig. 5), into which the surgeon places the working part 4 of the retractor 1. The retractor 1 is held by the surgeon by the holder 5. Thanks to the hook 8, the surgeon pulls the retractor 1 with one hand, pulling the skin 11 of the incision 10, and provides convenient access and/or overview of the dissection area. With the second hand, the surgeon can carry out the actions necessary for the operation.

Thus, the solutions used in the utility model provide a non-traumatic expansion of the area of dissection of the patient’s skin so that the surgeon can gain access and/or visibility when performing front-lifting operations, and thereby ensure the achievement of a technical result.
