[0030] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings of the specification.

[0031] In the following description, numerous specific details are set forth to facilitate a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Secondly, as used herein, "one embodiment" or "an embodiment" refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other.

[0033] Embodiment 1

[0034] Referring to Figures 1 - 10 , this is the first embodiment of the present invention. This embodiment provides an external skin expander. The external skin expander includes a main body component 100, which includes an adhesive plate 101 and a connecting belt 102. The connecting belt 102 is located on one side of the adhesive plate 101.

[0035] Both the adhesive plate 101 and the connecting belt 102 can be appropriately bent. One side of the adhesive plate 101 has an adhesive that can be pasted onto the skin. There are two adhesive plates 101. By pulling the connecting belt 102, the relative positions of the two adhesive plates 101 can be changed, thereby applying an expanding or contracting tension to the skin. The adhesive plate 101 and the connecting belt 102 can adaptively bend into an annular state and can adapt to the shapes required in different lesion spaces. When the bending amplitude of the skin surface is relatively large, the adhesive plate 101 can still be attached to the skin, and the connecting belt 102 will also bend to the corresponding amplitude. Then, through the cooperation of the adhesive plate 101 and the connecting belt 102, an accurate corresponding tension is applied to the skin.

[0036] An adjusting component 200 is located on the adhesive plate 101 and includes a fixing member 201. The fixing member 201 includes a first fixing block 201a, a second fixing block 201b, and a third fixing block 201c. The first fixing block 201a is fixed to the adhesive plate 101, the second fixing block 201b is fixed to the adhesive plate 101, and the third fixing block 201c is located on one side of the second fixing block 201b.

[0037] The setting of the fixing member 201 provides positioning for the connecting belt 102. The first fixing block 201a, the second fixing block 201b, and the third fixing block 201c are all fixed to the bonding plate 101. However, the first fixing block 201a is fixed to one of the bonding plates 101, while the second fixing block 201b and the third fixing block 201c are fixed to the other bonding plate 101.

[0038] Through holes corresponding to the connecting belt 102 are formed in the first fixing block 201a, the second fixing block 201b, and the third fixing block 201c.

[0039] Through the cooperation of the first fixing block 201a, the second fixing block 201b, and the connecting belt 102, a tension reduction function can be achieved. Through the cooperation of the second fixing block 201b, the third fixing block 201c, and the connecting belt 102, an expansion function can be achieved.

[0040] The adjusting assembly 200 further includes an adjusting member 202, which is arranged in the second fixing block 201b and includes a limiting block 202a, a first spring 202b, a locking block 202c, an auxiliary plate 202d, and a second spring 202e. A first moving groove 201b-1 is formed in the second fixing block 201b. The limiting block 202a slides in the first moving groove 201b-1. A limiting groove 102-1 is formed in the connecting belt 102, and the limiting groove 102-1 can be engaged with the limiting block 202a. Both ends of the first spring 202b are fixed to the limiting block 202a and the inner wall of the first moving groove 201b-1. A second moving groove 201b-2 is formed in the second fixing block 201b. The locking block 202c slides in the second moving groove 201b-2. The auxiliary plate 202d is fixed to the locking block 202c. One end of the second spring 202e is fixed to the auxiliary plate 202d and the other end is fixed to the second fixing block 201b.

[0041] The setting of the adjusting member 202 is used to adjust the relative position between the connecting belt 102 and the second fixing block 201b. Through the cooperation of the limiting block 202a and the limiting groove 102-1, the relative position between the connecting belt 102 and the second fixing block 201b can be adjusted.

[0042] A locking groove 202a-1 corresponding to the locking block 202c is formed in the limiting block 202a. The locking block 202c is used to lock the engaging state between the limiting block 202a and the limiting groove 102-1, thereby locking the position of the connecting belt 102 and the second fixing block 201b.

[0043] The first spring 202b applies a continuous thrust to the limiting block 202a to ensure that the limiting block 202a can be engaged with the limiting groove 102-1 without other external forces. The second spring 202e applies a continuous thrust to the locking block 202c for the reset of the locking block 202c.

[0044] The adjustment assembly 200 also includes an auxiliary part 203, which is located on the third fixed block 201c, including a first auxiliary block 203a and a third spring 203b. The third fixed block 201c is provided with a first slide groove 201c-1, the first auxiliary block 203a slides in the first slide groove 201c-1, the third spring 203b is fixed to the first auxiliary block 203a, and a rectangular groove 102-2 is provided on the connecting belt 102, and the first auxiliary block 203a can be engaged with the rectangular groove 102-2.

[0045] The auxiliary member 203 is provided to assist the adjusting member 202 in completing the tension reduction and expansion functions. There are multiple rectangular grooves 102-2, so as to facilitate the adjustment of the relative position of the third fixed block 201c and the connecting belt 102, thereby completing the expansion function. The third spring 203b applies a continuous thrust to the first auxiliary block 203a to ensure that the first auxiliary block 203a will not be separated from the first slide groove 201c-1 in the absence of other external forces, and the first auxiliary block 203a can be engaged with the rectangular groove 102-2. When the two are engaged, the relative position of the third fixed block 201c and the connecting belt 102 is fixed.

[0046] A pulling block 203e is fixed to one end of the first auxiliary block 203a, and the pulling block 203e is used to pull the first auxiliary block 203a to separate it from the rectangular groove 102-2.

[0047] A first pull tab 102a and a second pull tab 102b are fixed at both ends of the connecting belt 102. Pulling the first pull tab 102a will drive the connecting belt 102 to move toward the first fixing block 201a, and pulling the second pull tab 102b will drive the connecting belt 102 to move toward the third fixing block 201c.

[0048] In the initial state, the two adhesive plates 101 are adhered to the appropriate position of the skin. At this time, the relative position of one end of the connecting belt 102 and the second fixing block 201b is fixed, and the first auxiliary block 203a at the other end is engaged with the rectangular groove 102-2, so that the position of the connecting belt 102 and the third fixing block 201c is fixed, and the skin is currently in a relaxed state.

[0049] When the expansion function is realized, the positions of the connecting belt 102 and the second fixed block 201b are fixed, the pull block 203e is pulled to compress the third spring 203b, the first auxiliary block 203a is separated from the rectangular groove 102-2, and the second pull tab 102b is pulled to drive the connecting belt 102 to move toward the third fixed block 201c, thereby shortening the distance between the second fixed block 201b and the third fixed block 201c, and pulling the skin between the second fixed block 201b and the third fixed block 201c.

[0050] Example 2

[0051] Reference Figures 1 - 10, which is the second embodiment of the present invention and is based on the previous embodiment.

[0052] Specifically, a third moving groove 201b-3 is formed in the second fixing block 201b, and a clamping block 202f is arranged in the third moving groove 201b-3. One end of the clamping block 202f is fixed with a fourth spring 202g.

[0053] A clamping groove 202c-1 is formed in the locking block 202c. The clamping block 202f can be engaged with the clamping groove 202c-1. The clamping block 202f is used to lock the position of the locking block 202c to ensure that the position of the locking block 202c will not move randomly, thereby avoiding affecting the relative position between the connecting belt 102 and the second fixing block 201b. The fourth spring 202g provides a continuous thrust for the clamping block 202f to enable the clamping block 202f to be engaged with the clamping groove 202c-1.

[0054] Specifically, the end face of the limiting block 202a has two inclined slopes, which together form a tip. The shape of the limiting groove 102-1 corresponds to that of the limiting block 202a, and there are multiple such grooves.

[0055] By setting the tip, when the locking block 202c is not engaged with the locking groove 202a-1, the connecting belt 102 can move bidirectionally without obstruction in the through hole of the second fixing block 201b, thereby cooperating to complete the functions of tension reduction and expansion.

[0056] When the connecting belt 102 moves relative to the second fixing block 201b, the inclined surface of the limiting groove 102-1 squeezes the inclined surface of the limiting block 202a, and the first spring 202b will be compressed, causing the limiting block 202a to separate from the limiting groove 102-1. As the connecting belt 102 moves, when the limiting block 202a and another limiting groove 102-1 are in coaxial position, they can be engaged again, and the process is repeated until the connecting belt 102 moves to a suitable position. At this time, the limiting block 202a is still engaged with one of the limiting grooves 102-1. Then, the locking block 202c is engaged with the locking groove 202a-1, thereby restricting the movement of the limiting block 202a and locking the relative position between the connecting belt 102 and the second fixing block 201b.

[0057] Specifically, a second sliding groove 201a-1 is formed in the first fixing block 201a, and a second auxiliary block 203c is arranged in the second sliding groove 201a-1. One end of the second auxiliary block 203c is fixed with a fifth spring 203d. An auxiliary groove 102-3 is formed in the connecting belt 102, and the second auxiliary block 203c can be engaged with the auxiliary groove 102-3.

[0058] Through the cooperation of the second auxiliary block 203c and the auxiliary slot 102-3, when the two are engaged, the position of the connecting belt 102 and the first fixing block 201a is fixed. At this time, pulling the second tab 102b drives the connecting belt 102 to move in the direction of the third fixing block 201c, thereby reducing the position of the first fixing block 201a and the second fixing block 201b, pulling the skin on both sides of the wound towards the middle and fixing it, effectively reducing the tension at the wound edge and facilitating later recovery.

[0059] One end of the second auxiliary block 203c is also fixed with a pulling block 203e. Since the relative position of one end of the connecting belt 102 and the second fixing block 201b is fixed in the initial state, and the other end, the first auxiliary block 203a, is engaged with the rectangular slot 102-2. After the operation, pulling the pulling block 203e compresses the third spring 203b, the first auxiliary block 203a separates from the rectangular slot 102-2, and pulling the first tab 102a drives the connecting belt 102 to move in the direction of the first fixing block 201a. At this time, pulling the pulling block 203e on the second auxiliary block 203c causes the second auxiliary block 203c to completely enter the second sliding slot 201a-1, which will not affect the insertion of the connecting belt 102 into the corresponding through hole in the first fixing block 201a. Then, releasing the pulling block 203e, the fifth spring 203d restores. When the second auxiliary block 203c and the auxiliary slot 102-3 are in the coaxial position, the two are engaged, thereby fixing the position of the connecting belt 102 and the first fixing block 201a. After that, pulling the second tab 102b again drives the connecting belt 102 to move in the direction of the third fixing block 201c, thereby reducing the position of the first fixing block 201a and the second fixing block 201b, pulling the skin on both sides of the wound towards the middle and fixing it, effectively reducing the tension at the wound edge and facilitating later recovery.

[0060] Specifically, the second auxiliary block 203c is rectangular.

[0061] The shape of the auxiliary slot 102-3 corresponds to the shape of the second auxiliary block 203c.

[0062] Specifically, one end of the clamping block 202f is fixed with a pulling rope 202h, and the other end of the pulling rope 202h is fixed with a pulling plate 202i.

[0063] Pulling the pulling plate 202i will drive the pulling rope 202h to move, thereby compressing the fourth spring 202g, and the clamping block 202f will be completely located in the third moving slot 201b-3. At this time, under the push of the second spring 202e, the locking block 202c will move upward, thereby separating from the locking slot 202a-1. At this time, the position of the limiting block 202a will not be locked, and the connecting belt 102 can move bidirectionally without hindrance in the through hole of the second fixing block 201b.

[0064] When it is necessary to lock the relative position of the connecting belt 102 and the second fixing block 201b, press the auxiliary plate 202d to drive the locking block 202c to move downward. When the clamping block 202f and the clamping groove 202c-1 are in the coaxial position, the fourth spring 202g pushes the clamping block 202f to engage with the clamping groove 202c-1, thereby locking the position of the locking block 202c. At this time, the locking block 202c will also engage with the locking groove 202a-1, thereby locking the position of the limiting block 202a, and fixing the position of the connecting belt 102 and the second fixing block 201b.

[0065] Embodiment 3

[0066] Referring to Figures 1 - 10 , this is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0067] Specifically, there are two sets of the limiting blocks 202a, the locking blocks 202c, and the clamping blocks 202f.

[0068] The two sets of limiting blocks 202a, locking blocks 202c, and clamping blocks 202f are symmetrically distributed.

[0069] Specifically, there are two bonding plates 101, and there are multiple adjusting assemblies 200, and the adjusting assemblies 200 are cross-symmetrically distributed.

[0070] Through the cross-distribution setting, when realizing the expansion function, the distance between the second fixing block 201b and the third fixing block 201c in each adjusting assembly 200 will be shortened, pulling the skin between the second fixing block 201b and the third fixing block 201c, thereby expanding the distance between the two bonding plates 101, so as to continuously generate an outward tension on the skin around the operation, and relatively expand the relaxed area of the skin around the operation.

[0071] When realizing the function of reducing tension, the positions of the first fixing block 201a and the second fixing block 201b in each adjusting assembly 200 will be reduced, shortening the distance between the two bonding plates 101, and pulling the skin on both sides of the wound towards the middle, thereby effectively reducing the tension at the wound edge and facilitating the later recovery.

[0072] Specifically, ventilation holes 102-4 are provided on the connecting belt 102.

[0073] When using the function of reducing tension after the operation, the connecting belt 102 will be located above the wound. By providing the ventilation holes 102-4, air can flow between the wound skin and the connecting belt 102, accelerating the evaporation of water vapor, keeping the skin dry, and facilitating the postoperative recovery.

[0074] Specifically, the main body component 100 further includes a display screen 103, a mechanical sensor 104, a temperature sensor 105, and a liquid sensor 106. The display screen 103 is fixed on the bonding plate 101. The mechanical sensor 104 is located on one side of the display screen 103. The temperature sensor 105 is fixed on the bonding plate 101. The liquid sensor 106 is located on one side of the temperature sensor 105.

[0075] The temperature sensor 105 and the liquid sensor 106 are in contact with the skin. The data of the sensors can be displayed on the display screen 103. The data is connected to the terminal device for full-process system management. The mechanical sensor 104 is used to detect the tension on the skin in real time. By adjusting the adjustment component 200, it is ensured that the tension is always within a safe range. The relatively safe range of the tension ≤ 30N. The temperature sensor 105 is used to detect the skin temperature. When the temperature exceeds 2°C, an automatic alarm will be triggered. The liquid sensor 106 is used to sense whether there is blood or fluid leakage. This is the prior art and will not be elaborated in this solution. And those skilled in the art can clearly understand the working principle.

[0076] During use, in the initial state, the two bonding plates 101 are pasted to the appropriate position on the skin. At this time, the relative position of one end of the connecting belt 102 and the second fixing block 201b is fixed, and the other end, the first auxiliary block 203a, is engaged with the rectangular groove 102-2, so that the position of the connecting belt 102 and the third fixing block 201c is fixed, and the current skin is in a relaxed state.

[0077] When implementing the expansion function, the position of the connecting belt 102 and the second fixing block 201b is fixed. Pull the pulling block 203e to compress the third spring 203b. The first auxiliary block 203a is separated from the rectangular groove 102-2. Pull the second tab 102b to drive the connecting belt 102 to move in the direction of the third fixing block 201c, so that the distance between the second fixing block 201b and the third fixing block 201c is shortened, and the skin between the second fixing block 201b and the third fixing block 201c is pulled. The distance between the second fixing block 201b and the third fixing block 201c in each adjustment component 200 will be shortened, and the skin between the second fixing block 201b and the third fixing block 201c will be pulled, thereby expanding the distance between the two bonding plates 101, so as to continuously generate an outward tension on the skin around the operation, and relatively expand the relaxed area of the skin around the operation.

[0078] After the operation is completed and the function of reducing tension needs to be realized, the pulling block 203e is pulled to compress the third spring 203b. The first auxiliary block 203a is separated from the rectangular groove 102-2, and the first tab 102a is pulled to drive the connecting belt 102 to move in the direction of the first fixing block 201a. At this time, the pulling block 203e on the second auxiliary block 203c is pulled to make the second auxiliary block 203c completely enter the second sliding groove 201a-1, which will not affect the insertion of the connecting belt 102 into the corresponding through hole in the first fixing block 201a. Then the pulling block 203e is released, and the fifth spring 203d is restored. When the second auxiliary block 203c and the auxiliary groove 102-3 are in the coaxial position, the two are engaged, so that the position of the connecting belt 102 and the first fixing block 201a is fixed. Then pulling the pull plate 202i will drive the pull rope 202h to move, and further compress the fourth spring 202g. The clamping block 202f will be completely located in the third moving groove 201b-3. At this time, under the push of the second spring 202e, the locking block 202c will move upward, so as to be separated from the locking groove 202a-1. At this time, the position of the limiting block 202a will not be locked, and the connecting belt 102 can move bidirectionally without hindrance in the through hole of the second fixing block 201b. At this time, pulling the second tab 102b drives the connecting belt 102 to move in the direction of the third fixing block 201c, and further reduces the position between the first fixing block 201a and the second fixing block 201b. The positions of the first fixing block 201a and the second fixing block 201b in each set of adjusting components 200 will be reduced, shortening the distance between the two bonding plates 101, and the skin on both sides of the wound will be pulled towards the middle, thus effectively reducing the tension at the wound edge and facilitating the later recovery.

[0079] When it is necessary to lock the relative position of the connecting belt 102 and the second fixing block 201b, the auxiliary plate 202d is pressed to drive the locking block 202c to move downward. When the clamping block 202f and the clamping groove 202c-1 are in the coaxial position, the fourth spring 202g pushes the clamping block 202f to engage with the clamping groove 202c-1, thereby locking the position of the locking block 202c. At this time, the locking block 202c will also engage with the locking groove 202a-1, thereby locking the position of the limiting block 202a and fixing the position of the connecting belt 102 and the second fixing block 201b.
