[0035] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0036] Since most gynecological patients are middle-aged and elderly women, their skin is loose and inelastic. When preparing the skin of the groin and perineum, there are many wrinkles, making it difficult to remove the hair cleanly, and the operation is difficult and time-consuming for nurses. In order to facilitate skin preparation and improve efficiency, the utility model provides a skin-stretching auxiliary device, such as Figures 1 to 3 As shown, the leather stretching auxiliary device includes: an end 1, a first support leg 2 and a second support leg 3; the upper ends of the first support leg 2 and the second support leg 3 are respectively hinged to the end 1, and the lower ends of the first support leg 2 and the second support leg 3 are respectively connected with a support member 4; a locking member is arranged on the end 1 for fixing the angle between the two support legs.

[0037] The terminal 1 comprises: a front plate 101, a rear plate 102, and a top plate 103. The front plate 101 and the rear plate 102 are arranged in parallel and perpendicular to the top plate 103, and the upper end of the front plate 101 is connected to the front end of the top plate 103, and the upper end of the rear plate 102 is connected to the rear end of the top plate 103, so as to form a structure with openings on the left, right and bottom sides.

[0038] The first leg 2 and the second leg 3 have the same structure, both of which are rod-shaped structures. The upper ends of the first leg 2 and the second leg 3 can be hinged to the end 1 through a variety of existing hinge structures. For example, the upper ends of the first leg 2 and the second leg 3 are respectively installed on the lower part of the end 1 through the rotating shaft 5, and the first leg 2 and the second leg 3 can rotate around the central axis of the rotating shaft 5. One end of the rotating shaft 5 is a large head end 501, and the other end is a threaded end. There is a smooth rod between the large head end 501 and the threaded end. The outer diameter of the large head end 501 is larger than the outer diameter of the smooth rod, and the outer diameter of the threaded end is equal to the outer diameter of the smooth rod. Specifically, two holes are respectively opened at the lower parts of the front plate 101 and the rear plate 102 of the terminal 1, and the holes on the front plate 101 and the rear plate 102 are arranged opposite to each other. Holes are opened at the upper ends of the first leg 2 and the second leg 3. The upper end of the first leg 2 is inserted between the front plate 101 and the rear plate 102, and the hole on the first leg 2 is aligned with the holes on the front plate 101 and the rear plate 102. After the threaded end of the rotating shaft 5 is passed through the hole of the front plate 101, the hole at the upper end of the first leg 2, and the hole on the rear plate 102 in sequence, it is connected with the nut 502 located on the rear side of the rear plate 102, and the big head end 501 of the rotating shaft 5 is located on the front side of the front plate 101. In this way, the upper end of the first leg 2 is hinged to the terminal 1 through the rotating shaft 5 and the nut 502, and the first leg 2 can rotate around the rotating shaft 5. Similarly, the second support leg 3 can be installed by using another rotation shaft 5, the nut 502 and another hole on the front plate 101 and the rear plate 102, so that the second support leg 3 can rotate around another rotation shaft 5. The two rotation shafts 5 are arranged in parallel.

[0039] The locking member includes a gasket 8 and a locking screw 6. Figure 2 As shown, each of the gaskets 8 has a central through hole, each rotating shaft 5 passes through the central through holes of two gaskets 8, and one gasket 8 is located between the upper end of the first leg 2 and the front plate 101, and the other gasket 8 is located between the upper end of the first leg 2 and the rear plate 102 (for clarity, Figure 2 The gap between the gasket 8 and the front plate 101, the rear plate 102 is enlarged in the figure, but in fact the gasket is in contact with the front plate 101, the rear plate 102). The gasket 8 can increase the friction between the first leg 2 and the front plate 101, the rear plate 102, so that the first leg 2 can stay at a desired angle. Similarly, gaskets 8 are also provided on both sides of the second leg 3, so that the second leg 3 can stay at a desired angle.

[0040] A threaded hole is provided on the upper part of the rear plate 102, and a light hole is provided on the upper part of the front plate 101, and the central axes of the light hole and the threaded hole are located on the same straight line, which is parallel to the central axis of the rotating shaft 5. The locking screw 6 can be screwed into the threaded hole of the rear plate 102 after passing through the light hole of the front plate 101. When the locking screw 6 is tightened, the front plate 101 and the rear plate 102 squeeze the gasket 8, and the gasket 8 squeezes the upper ends of the first leg 2 and the second leg 3, so that the angle between the first leg 2 and the second leg 3 can be fixed. When the angle between the first leg 2 and the second leg 3 needs to be adjusted, the locking screw 6 is loosened, and the angle between the first leg 2 and the second leg 3 is increased or decreased to the desired angle, and then the locking screw 6 is tightened again, so that the angle between the first leg 2 and the second leg 3 can be maintained when the leather is stretched. Preferably, an anti-slip pattern is provided on one end of the locking screw 6 located on the front side of the front plate 101, so that it is convenient to tighten or loosen the locking screw 6 by hand.

[0041] Preferably, the support member 4 is an arc-shaped structure, one end of which is a connecting end and the other end is a free end. The lower end of the first leg 2 is fixedly connected to the connecting end of one support member 4, and the lower end of the second leg 3 is fixedly connected to the connecting end of the other support member 4 (for example, a blind hole can be opened at the connecting end of the support member 4, and the lower ends of the first leg 2 and the second leg 3 are inserted into the blind hole). The two support members 4 are symmetrically arranged, and the arc-shaped openings of the two support members 4 are opposite to each other, such as Figure 3 As shown ( Figure 3 The locking screw 6, the rotating shaft 5, and the nut 502 are not shown in the figure). The purpose of designing the stretching member 4 into an arc structure is to make the stretching member 4 contact the skin with a larger area, so that the friction force is also greater, thereby achieving a better skin stretching effect. Preferably, the shape of the stretching member 4 is a part of an ellipse.

[0042] Preferably, the center line of the first leg 2 and the center line of the second leg 3 are located in the same plane, the center lines of the two support members 4 are located in the same plane, and the two planes are perpendicular to each other, that is, when the two support members 4 are parallel to the skin, the plane where the center line of the first leg 2 and the center line of the third leg 3 are located is perpendicular to the skin.

[0043] Preferably, the spreading member 4 is made of silicone, which has a certain elasticity and can protect the skin. Preferably, the cross-sectional shape of the spreading member 4 is circular, so that no matter what angle the two legs are at, the spreading member 4 can fully contact the skin.

[0044] Preferably, anti-slip grooves are provided on the outer surface of the expansion piece 4, which can further increase the friction between the expansion piece 4 and the skin.

[0045] Preferably, in order to facilitate gripping, a handle 7 is connected to the end 1. Specifically, Figure 1As shown, the right end of the handle 7 is connected to the upper end of the top plate 103, and the left end of the handle 7 is a free end. Preferably, protective particles are arranged on the outer surface of the handle 7.

[0046] When in use, after selecting the skin stretching range, adjust the angle between the first leg 2 and the second leg 3 (the larger the angle, the farther the distance between the two stretching members 4, and the larger the skin stretching range), and tighten the locking screw 6 to fix the angle between the two legs. Press the two stretching members 4 on the skin surface, hold the handle 7 with one hand to tighten the skin, so that the skin between the two stretching members 4 is flat, and then use the other hand to prepare the skin. It can be seen that the area of ​​the skin between the two stretching members 4 is much larger than the area that can be stretched by two fingers of one hand, and it is more stable.

[0047] By using the utility model, a large area of ​​skin can be stretched with one hand and the skin can be stretched for a long time, and the skin stretching effect is better. Moreover, the handle 7 is on the side, so the nurse has a wider field of vision, which is convenient for the nurse to operate and improves the nurse's work efficiency. Moreover, after the nurse's skin preparation time is shortened, the time the patient is in the lithotomy position is also shortened accordingly, which reduces the patient's discomfort. In addition, the utility model can fix the angle after adjusting the angles of the two legs, and a large area of ​​skin can be stretched with one hand. The skin stretching is flat and stable, and it is not easy to scratch the patient's skin, which improves safety and reduces the risk of infection. The stretching piece 4 that contacts the patient's skin is made of silicone material, which improves the patient's comfort.
