Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic surgery and beauty, in particular to a double-head retractor. Background Art
[0002] A facelift utilizes the skin's elasticity to lift loose skin back and upward, remove excess skin, and simultaneously tighten the deep facial fascia. Incisions are often made within the hairline, near the ear, or in a discreet area behind the ear to achieve a firming effect. To achieve a quick and complete skin separation, a retractor is used during the procedure to lift the separated skin, widening the gap between the skin and subcutaneous tissue, allowing the scissors to continue to separate the skin more deeply.
[0003] Since different types and models of retractors are needed during surgery, frequent replacement of instruments prolongs the operation time. Moreover, the retractors have relatively simple functions and are expensive to produce and purchase. In addition, retractors that are perpendicular to the handle also have limitations when used. Not only are they laborious and prone to fatigue, but the handle can also easily block the view. Utility Model Content
[0004] In view of the deficiencies in the prior art, the present invention provides a double-headed retractor to solve the technical problems in the related art that traditional retractors have a single function and limitations in use.
[0005] The utility model provides a double-head hook retractor, comprising:
[0006] A handle having a first end and a second end disposed opposite to each other, wherein a cross-sectional area of the handle gradually increases and then gradually decreases along the direction from the first end to the second end;
[0007] a first retractor hook provided at the first end of the handle;
[0008] a second retractor hook, provided at the second end of the handle;
[0009] Wherein, at least one of the first retractor hook and the second retractor hook is arranged obliquely relative to the handle, and the bending directions of the two retractor hooks are opposite.

[0021] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0023] In the embodiment of the present utility model, Figure 1As shown, the double-headed retractor comprises: a handle 1, a first retractor 2 and a second retractor 3; the handle 1 has a first end and a second end arranged opposite to each other, and the cross-sectional area of the handle 1 gradually increases and then gradually decreases along the direction from the first end to the second end; the first retractor 2 is arranged at the first end of the handle 1; the second retractor 3 is arranged at the second end of the handle 1; wherein, at least one of the first retractor 2 and the second retractor 3 is arranged obliquely relative to the handle 1, and the bending directions of the two retractors are opposite.
[0024] Specifically, in an embodiment of the present invention, the handle 1 has a first end and a second end arranged opposite to each other, which are used to connect the first retractor 2 and the second retractor 3, so that the retractor has a double-headed retractor structure, which reduces the number of preoperative instrument preparations and the number of postoperative disinfections. There is no need to repeatedly replace the retractors during the operation, which saves time spent on replacing instruments during the operation; in addition, the two retractors use the same handle 1, which can save one handle 1 compared to a single retractor, thereby reducing production costs and giving the retractor dual functions.
[0025] At the same time, the cross-sectional area of the handle 1 gradually increases and then decreases from its first end to the second end, i.e., the cross-sectional area of the middle portion of the handle 1 is the largest, and the cross-sectional area of the first and second ends of the handle 1 is the smallest. Furthermore, the first and second ends of the handle 1 can be mirror images of the middle portion of the handle 1. Thus, compared to a conventional columnar grip, the cross-sectional area of the connection between the handle 1 and the retractor is smaller, which not only reduces the weight of the handle 1 itself but also reduces the area of the skin obstructed by the handle 1 during surgery, facilitating more precise separation of the skin and subcutaneous tissue. Of course, during surgery, the handle 1 is held at its largest area to increase the contact area with the hand, facilitating operation.
[0026] On the other hand, at least one of the first hook 2 and the second hook 3 is arranged obliquely relative to the handle 1 (eg Figure 1 As shown, this embodiment uses the second retractor 3 at an angle as an example. The angled retractor not only facilitates skin retraction but also allows for a smaller angle of inclination during the retraction process. Compared to a straight retractor, its smaller angle of inclination reduces fatigue even when maintaining the same position for extended periods. Furthermore, the angled connection between the handle 1 and the retractor reduces obstruction of the incision, facilitating faster and more precise separation of the skin and subcutaneous tissue. Furthermore, the first and second retractors 2 and 3 curve in opposite directions, facilitating the application of force during retraction; the angled angles also facilitate quick identification of the two retractors.
[0027] The utility model provides a first retractor 2 and a second retractor 3 at the first end and the second end of the handle 1 respectively, so as to replace the original single-head retractor with a double-head retractor, thereby improving the versatility of the retractor and making it have a dual-function structure; at the same time, by defining the cross-sectional area of the handle 1 and the angle between the retractor and the handle 1, the comfort of the retractor is improved, and even if the same posture is maintained for a long time, fatigue is not easily generated, and more effort is saved.
[0028] like Figure 1 As shown, in one embodiment, the shape of the first retractor 2 and the shape of the second retractor 3 are the same or different. Specifically, to provide the retractor with multiple functions, this embodiment provides different shapes for the first and second retractors 2 and 3, thereby facilitating selection of the appropriate retractor for different incisions. Of course, in other embodiments, the shapes of the first and second retractors 2 and 3 may be the same, but their sizes may be different, allowing selection of the appropriate retractor size based on actual needs.
[0029] like Figure 1 As shown, in one embodiment, the first retractor 2 and / or the second retractor 3 are provided with a plurality of notches 201 extending along their curvature. Specifically, to reduce the weight of the retractor and facilitate facelift surgery, since the first and second retractor 2 and 3 in this embodiment have different shapes, this embodiment only provides a plurality of notches 201 at intervals on the first retractor 2. One end of the notch 201 extends beyond the first retractor 2 to break the end of the first retractor 2; the other end of the notch 201 is provided along the curvature of the first retractor 2 and extends to the smooth section of the first retractor 2. Preferably, the connection between the first retractor 2 and the notch 201 is rounded to provide a smoother connection.
[0030] like Figure 1 As shown, in one embodiment, the first retractor 2 and / or the second retractor 3 are provided with a retractor head 4, one end of which is tilted toward the handle 1. Specifically, in order to further pull the skin and prevent the skin from slipping off the retractor, since the first retractor 2 and the second retractor 3 in this embodiment have different shapes, a retractor head 4 is integrally formed at the end of the second retractor 3 in this embodiment. The end of the retractor head 4 facing away from the second retractor 3 is tilted toward the handle 1. In this way, the gap in the curved portion of the second retractor 3 can be partially closed, so that the pulled skin can remain in the cavity formed between the two.
[0031] like Figure 1As shown, in one embodiment, the angle α between the first retractor 2 and / or the second retractor 3 and the handle 1 is defined as α, where α satisfies 90° < α < 180°. In order to ensure that at least one of the two retractors is disposed at an angle relative to the handle 1, and fundamentally as described above, the second retractor 3 in this embodiment is disposed at an angle relative to the handle 1. Therefore, in this embodiment, the angle α1 between the first retractor 2 and the handle 1 is defined as α1 = 180°, and the angle α2 between the second retractor 3 and the handle 1 is defined as α2, where 90° < α2 < 180°. Of course, in other embodiments, the angle values of α1 and α2 may be interchangeable or both may be between 90° and 180°, and this is not a limitation here.
[0032] like Figure 1 As shown, an anti-slip pattern 5 is provided between the first end and the second end of the handle 1, which can effectively prevent slipping during surgery.
[0033] The first retractor 2, the handle 1, and the second retractor 3 are sequentially connected and integrally formed. Compared to existing detachable connection methods, this embodiment adopts an integrally formed manufacturing process to avoid gaps between adjacent components, which not only saves processing costs but also facilitates postoperative disinfection and prevents bacteria from accumulating in the gaps and causing intraoperative infection.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
