Detailed Description
The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
Example 1
A skin retractor is shown in figures 1 and 2 and comprises a stay bar 1 and an elastic part 2, wherein the stay bar 1 comprises a handheld part 11 and a distraction part 12 which are respectively positioned at two ends of the stay bar 1, and a corner downward probing part 13 positioned between the handheld part 11 and the distraction part 12; the support rods 1 are provided with a pair of support rods and are arranged in a mutually crossed manner, and the two support rods 1 are rotatably connected at the crossed intersection point; the spatial planes of the two handholds 11 and the spatial planes of the two expansion parts 12 are staggered and parallel to each other. The skin spreader also comprises a rotating shaft 3, the rotating shaft 3 is perpendicular to a space plane where the two handheld parts 11 are located, the two handheld parts 11 are respectively and rotationally connected with the rotating shaft 3, and the rotating shaft 3 is located at an intersection point position where the two handheld parts 11 are intersected with each other. Two ends of the rotating shaft 3 are respectively in threaded connection with adjusting nuts 4, the two handheld portions 11 are located between the two adjusting nuts 4, and the adjusting nuts 4 can prevent the two handheld portions 11 from moving along the axis direction of the rotating shaft 3 to separate from the rotating shaft 3.
During operation, the two handheld portions 11 are held by hands, after the two handheld portions 11 are held tightly, the two handheld portions 11 move towards the directions close to each other, the handheld portions 11 rotate around the rotating shaft 3 to drive the two opening portions 12 to move towards the directions close to each other, after the distance between the two opening portions 12 is reduced, the two opening portions 12 are inserted into a skin gap to be opened, the two handheld portions 11 are opened by hands, and the two opening portions 12 are driven to open the skin. The main surgeon can use the skin retractor to retract the skin without an additional assistant and can control the opening angle, the opening force and the opening position at any time according to the requirements.
The corner downward probing part 13 enables the distraction part 12 and the handheld part 11 to be mutually staggered, so that the distraction part 12 can be conveniently stretched into a skin wound outside the skin wound, and the hand or the handheld part 11 is prevented from contacting the wound.
Referring to fig. 3, the two hand-held portions 11 are respectively and fixedly connected with the connecting blocks 5, the elastic member 2 is a spring, and two ends of the spring are respectively and fixedly connected with the two connecting blocks 5. The two handheld parts 11 are held by hands, after the two handheld parts 11 move towards the direction of approaching each other, the two spreading parts 12 move towards the direction of separating from each other, the two handheld parts 11 compress the spring, and the spring is deformed and shortened; after hands are loosened, the spring gradually recovers deformation and elongation, the stretching part 12 automatically stretches the skin, and a doctor can separate the hands controlling the skin retractor from the skin retractor to process other work, so that the work efficiency is improved.
The surfaces of the two stretching parts 12, which are far away from each other, are respectively provided with stretching surfaces 121, and the stretching surfaces 121 can increase the contact area between the stretching parts 12 and the skin and reduce the damage to the skin in the process of stretching the skin.
Example 2
A skin retractor, which is different from embodiment 1 in that, as shown in fig. 4, a cushion 6 is fixedly connected to a spreading surface 121 (see fig. 3), and the cushion 6 has elasticity (a silica gel cushion, an airbag cushion, an elastic rubber cushion, etc. can be used).
Example 3
A skin retractor is different from embodiment 2 in that, as shown in fig. 5, a cushion 6 is long, a fitting surface 61 which is concave toward the direction of approaching the opening surface 121 is provided on a surface of the cushion 6 which is away from the opening surface 121, and the fitting surface 61 is located at the center of the cushion 6 and is provided along the length direction of the cushion 6. The abutting surface 61 can increase the contact area between the skin and the cushion pad 6, and the concave abutting surface 61 can position and keep the skin edge at the central position of the cushion pad 6, so that the possibility of the skin slipping off from the edge of the cushion pad 6 is reduced.
Example 4
A skin retractor differs from embodiment 2 in that a dressing 7 is detachably and fixedly connected to the side of the cushion 6 away from the opening surface 121, as shown in fig. 6. The two side surfaces of the cushion pad 6 are provided with clamping grooves 62 along the length direction for fixing and clamping the side edges of the dressing 7. The dressing 7 can be made of materials such as sterile gauze, and the dressing 7 can prevent the skin wound from directly contacting with the cushion pad 6, so that the risk of wound infection is reduced. The slot 62 facilitates the replacement of the used dressing 7 and the cleaning of the cushion pad 6.
Example 5
A skin retractor is different from embodiment 1 in that, as shown in fig. 7, the central positions of two spreading surfaces 121 are curved in directions away from each other, and in this embodiment, the spreading surfaces are preferably curved into a cylindrical surface, and the central axes of the spreading surfaces 121 are parallel to the central axis of the rotating shaft 3. The curved opening surface 121 can increase the contact area with the skin, and when the skin retractor is moved along the skin to finely adjust the position of the skin retractor, the frictional resistance between the opening surface 121 and the skin can be reduced, and the comfort of the wounded is improved. The edge of the strutting part 12 is provided with a smooth transition curved surface (not marked in the figure), which can reduce the contact area between the edge of the strutting part 12 and the skin, reduce the scraping acting force of the strutting part 12 to the skin and improve the comfort of the wounded.
