Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a multi-angle skin stretcher. Background Art

[0002] It is common in clinical practice that skin wounds cannot be directly closed and sutured due to excessive tension on the wound edges. In the past, skin grafting or flap transfer surgery was required for repair, but it was traumatic, required long hospital stays, and had high medical costs. In recent years, skin external stretching technology has been introduced into the clinical treatment of such wounds that are difficult to suture directly. The principle is to use the looseness and extensibility of the skin, and use an external stretcher to pull the skin edges on both sides of the wound toward the center, gradually shrink the wound, and finally suture to eliminate the wound surface.

[0003] Skin stretching and extension surgery uses a skin stretch closure device and takes advantage of the extensibility of the skin to stretch the normal skin on both sides of the skin defect under external force, gradually reducing or bringing the wound edges closer together, achieving stress relaxation of the skin to obtain "extra" skin, and reducing or closing the wound. It has the characteristics of no need for skin grafting, rapid wound closure, and reduced complications, and is becoming a new treatment method for skin defects.

[0004] However, in the prior art, it is difficult to achieve effective traction for round or irregular wounds, and the traction force required at various positions on the wound edge is relatively complex. Applying a fixed traction force to the skin around the wound has a poor effect on relaxing the skin, and medical staff need to adjust the tension daily, which takes up a lot of manpower and material resources and reduces work efficiency. Summary of the invention

[0015] Beneficial Effects

[0016] In the present invention, when in use, multiple connected adhesive stickers are torn off, and the adhesive stickers are adhered to the skin around the wound according to the contour of the patient's wound. The angle of the rope hole of the rotating part is adjusted according to the shape of the wound, and the adhesive sticker provided with the connection base is also fixed on the surface of the patient's skin. By rotating the control part and tightening the traction rope, the adhesive sticker drives the skin around the wound, stretches the skin at the wound, and forces the wound to close and keep the wound closed. When the device needs to be removed, the control part is pressed, and the curled traction rope will be released, so that the adhesive sticker no longer pulls the skin at the patient's wound. Through the above structure, the patient's wound can be stretched and closed non-invasively without causing secondary injury to the patient. At the same time, by adjusting the angle of the rope hole of the rotating part, the device can adjust the tension provided by the adhesive tape at the corresponding angle of the wound to effectively close the circular or irregular wound.

[0026] In order to make the purpose, scheme and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments of the present invention.

[0027] Example: Please refer to Figures 1 to 6 : The present invention provides a multi-angle skin stretcher, comprising: The adhesive patch 101 is adhered around the patient's wound. There are at least two types of adhesive patches 101. A fixed base 103 is set at the upper end of one adhesive patch 101, and is rotatably connected to a rotating member 104 through the fixed base 103. There is damping between the rotating member 104 and the fixed base 103. The rotating member 104 adjusts the angle of the traction rope 3, so that after the two ends of the traction rope 3 are tightened, the adhesive patch 101 can be pulled at different angles to stretch the open wound and force the wound to close.

[0028] The traction rope 3 is connected in series with at least two rotating parts 104, and the traction rope 3 and the rotating parts 104 slide relative to each other; after the adhesive patch 101 is adhered, the displacement of the two ends of the traction rope 3 will cause the rotating parts 104 to drive the adhesive patch 101 to pull the skin around the patient's wound, so that the skin around the wound is stretched in the direction of the force of the traction rope 3.

[0029] Among them, Figure 2 , Figure 3 As shown, connecting teeth 102 are provided between the two sides of at least two connected stickers 101; the multiple stickers 101 are connected by the connecting teeth 102, and can be conveniently stored when not in use, and can be quickly torn apart when in use. Since the multiple stickers 101 are also connected by the traction rope 3, there is no need to worry about the loss of a single sticker 101 when not in use or in use. At the same time, the stickers 101 and other structures are separated by a design, and the stickers 101 can be replaced separately as consumables, and other structures can be reused.

[0030] Among them, Figure 2 As shown, the fixed base 103 is fixedly connected to the adhesive tape 101, and a damping bearing is provided at the upper end of the fixed base 103; the rotating member 104 is connected to the fixed base 103 through the damping bearing; the rotating member 104 rotates on the fixed base 103, and at the same time, it is acted upon by the damping bearing, so that the rotating member 104 can be fixed on the fixed base 103 at any angle, and there is a certain angle between the rotating member 104 and the traction rope 3. When this angle changes, the stress between the rotating member 104 and the traction rope 3 will also change. When treating irregular wounds, there will inevitably be a situation where the curvature of the same wound is larger at one place and smaller at another place. If all the adhesive tapes 101 are subjected to equal force, the forces required at positions with different curvatures of the wound are also the same. There will inevitably be a problem where the force at the large curvature of the wound is too small, resulting in a poor stretching effect, or a problem where the force at the small curvature of the wound is too large, which is easy to cause secondary injuries. In this device, different pulling forces are provided for different positions by adjusting the angle between the rotating member 104 and the fixed base 103.

[0031] Among them, Figure 2 As shown, a rope hole is provided at the upper end of the rotating member 104, and the traction rope 3 passes through the rope hole and can slide in the rope hole; since the rotating member 104 can be fixed on the fixed base 103 at any angle through damping, when encountering an irregular wound, the angle of the rope hole of the rotating member 104 can be adjusted to change the pulling force on the skin given by the corresponding rotating member 104 and the adhesive tape 101 to adapt to the traction of the irregular wound.

[0032] Among them, Figure 4As shown, the upper end of another adhesive sticker 101 is fixedly connected to a connecting base 201; the upper end of the connecting base 201 is connected to a protective shell 205, and a mounting groove is opened at the bottom center of the connecting base 201; a rotating groove is provided on the bottom surface of the mounting groove; the rotating groove of the connecting base 201 is used to install a control part 202, and a roller 203, a spring 206 and a limit card 204 are installed in the mounting groove.

[0033] Among them, Figure 5 As shown, a spring 206 is placed at the bottom of the installation groove, and a limit card 204 is fixedly installed along the inner wall of the installation groove; the limit card 204 is an elastic structure, and a clamping tooth is provided on the side of the limit card 204 pointing to the center of the installation groove; the spring 206 is used to lift the control member 202, so that the limit teeth at the lower end of the control member 202 and the limit teeth at the upper end of the roller 203 are engaged, so that the roller 203 is axially locked by the limit card 204 and no longer rotates, thereby locking the length of the traction rope 3. When the control member 202 is pressed, the spring is compressed, the limit teeth of the control member 202 and the roller 203 are disengaged, and the roller 203 can rotate, so that the traction rope 3 rolled up by the roller 203 is released.

[0034] Among them, Figure 5 As shown, a roller 203 is also inserted into the installation groove; the roller 203 is a storage shaft, and the end surface of the roller 203 pointing to the inside of the installation groove is provided with circumferentially arranged limit teeth; the roller 203 is axially locked by the control member 202, and when the control member 202 rotates, it will rotate together, and at the same time, the two ends of the traction rope 3 are fixed on the surface of the roller 203. When the roller 203 rotates, the traction rope 3 will be received by the roller 203, thereby causing the two ends of the traction rope 3 to be displaced.

[0035] Among them, Figure 4 As shown, it also includes a control member 202; the control member 202 passes through the inside of the roller 203 and slides up and down along the roller 203 in the vertical direction; the outer side of the lower end of the control member 202 is provided with circumferentially arranged rotating teeth, and the teeth of the limit card 204 are inserted between two rotating teeth; the end surface of the control member 202 in contact with the roller 203 is provided with a limit tooth, and the limit teeth of the control member 202 and the roller 203 are engaged with each other; the rotating teeth of the control member 202 have an arc, and when rotating clockwise, the elastic limit card 204 will elastically deform along the arc of the rotating teeth, so that the rotating teeth rotate through, and when rotating counterclockwise, the rotating teeth will lock the teeth of the limit card 204, so that the rotating member 104 cannot rotate, thereby achieving limiting.

[0036] Among them, Figure 5 As shown, the height of the control member 202 lifted by the spring 206 is greater than the tooth height of the limiting teeth of the control member 202; after the control member 202 is bounced up by the spring, the limiting teeth of the control member 202 and the roller 203 are engaged.

[0037] Among them, Figure 6 As shown, both ends of the traction rope 3 are fixedly connected to the outer surface of the roller 203 ; when the roller 203 rotates, the traction rope 3 will be driven and wound around the outer side of the roller 203 .

[0038] In another embodiment, an electric control component is included, which is composed of a controller and a motor. The motor of the electric control component is connected to the control component 202 and the rotating component 104. After the daily pulling amount is set by the controller, the controller will drive the control component 202 or the rotating component 104 to rotate through the motor every day to adjust the overall pulling force of the device.

[0039] Specific usage and function of this embodiment: In the present invention, when in use, tear off multiple connected adhesive stickers 101, and adhere the adhesive stickers 101 to the skin around the wound according to the contour of the patient's wound, adjust the angle of the rope hole of the rotating part 104 according to the shape of the wound, and fix the adhesive sticker 101 provided with the connecting base 201 on the surface of the patient's skin. By rotating the control part 202 and tightening the traction rope 3, the adhesive sticker 101 drives the skin around the wound, forcing the wound to close and keep the wound closed. When the device needs to be removed, press the control part 202, the curled traction rope 3 will be released, so that the adhesive sticker 101 will no longer pull the skin at the patient's wound.
