[0043] One end of the traction belt 4 is a movable end, and the movable end is movably provided with the vertical plate 2; the winding assembly 6 includes a winding shell 6.1, a winding operation part and a winding shaft 6.5, the winding shell 6.1 is provided with a contact plate 6.2, the contact plate 6.2 is arranged at a distance from the winding shaft 6.5, and is used to be detachably placed on the top of one of the traction base plates 1 and the vertical plate 2 of the traction base plate 1; the winding shaft 6.5 is connected to the winding operation part, which is used to be detachably connected to the movable end of the traction belt 4, and the traction belt 4 is wound under the action of the collecting operation part to bring the two traction base plates 1 closer together. The traction belt 4 is shortened by the winding assembly 6, and the shortening of the traction belt 4 drives the two traction base plates 1 closer together, thereby achieving skin traction.

[0044] In this embodiment, the winding operation part includes an operating rod 6.3, which is rotatably mounted on the winding housing 6.1, and one end of which is connected to the winding shaft 6.5. The winding operation of the traction belt 4 is realized by rotating the operating rod 6.3 to drive the winding shaft 6.5 to rotate. Preferably, the winding operation part also includes a winding motor 6.4, which is mounted on the winding housing 6.1, and the output shaft of which is connected to the end of the operating rod 6.3 that is not connected to the winding shaft 6.5. That is, the winding of the traction belt 4 is realized by the winding motor 6.4 causing the operating rod 6.3 to rotate. The winding motor 6.4 replaces manual pulling, and the pulling is more convenient and has a better effect.

[0045] In the present invention, the winding shaft 6.5 is used to wind the traction belt 4, and it is connected to the traction belt 4 by connecting to the movable end of the traction belt 4, wherein the winding shaft 6.5 is connected to the movable end of the traction belt 4 in a detachable manner, which makes it possible for the winding component 6 to be detached from the traction belt 4 after a single pulling and then be ready for the next use, thereby realizing the function of reusing the winding component 6 and avoiding waste of resources. Preferably, the winding shaft rod 6.5 includes a winding shaft 6.5.1, a winding clamping rod 6.5.2 and a winding shaft connecting plate 6.5.3; the winding shaft 6.5.1 and the winding clamping rod 6.5.2 are parallel and spaced apart, one end of both are mounted on the winding shaft connecting plate 6.5.3, and the winding shaft connecting plate 6.5.3 is connected to the operating rod 6.3; a clamping slot is provided on the winding clamping rod 6.5.2, and a clamping strip 4.1 is provided on the movable end of the traction belt 4, and the traction belt 4 is detachably mounted on the winding clamping rod 6.5.2 by means of the clamping strip 4.1 clamping the clamping slot 6.5.2.1, and the winding clamping rod 6.5.2 and the winding shaft 6.5.1 are simultaneously wound by the action of the winding operating part. Furthermore, the end of the winding clamp rod 6.5.2 and the winding shaft 6.5.1 that is not connected to the winding shaft connecting plate 6.5.3 is detachably connected to the winding shaft cover plate 6.5.4, and the covering effect of the winding shaft cover plate 6.5.4 prevents the clamping strip on the traction belt 4 from escaping from the clamping slot 6.5.2.1 on the winding clamp rod 6.5.2; wherein, the winding shaft cover plate 6.5.4 can be detachably connected to the winding clamp rod 6.5.2 and the winding shaft 6.5.1 by a snap-on manner, or the threaded rod on the winding clamp rod 6.5.2 and the winding shaft 6.5.1 can be inserted into the receiving shaft cover plate 6.5.4 and then locked with a nut to achieve detachable connection, or the detachable connection can be achieved through other structures. In order to facilitate the traction belt 4 wound on the winding shaft 6.5 to be separated from the winding assembly 6, the winding shaft 6.5 is preferably detachably connected to the operating rod 6.3, which has a detachable connection through a card block and a card slot, so that the traction belt 4 can be conveniently removed after the entire winding shaft 6.5 is detached from the winding shell 6.1.

[0046] In the present invention, the winding assembly 6 is placed on the traction base plate 1 and the vertical plate 2 through the abutment plate 6.2. For better placement, preferably, two abutment plates 6.2 are installed on the winding shell 6.1, and the traction belt 4 is located between the two abutment plates 6.2. In order to prevent the winding assembly 6 from being separated from the traction base plate 1 during the winding process, preferably, the abutment plate 6.2 can be detachably bonded to the traction base plate 1 and the vertical plate 2, so as to be stably connected to the traction base plate 1 and the vertical plate 2 by pasting and fixing. In addition, this embodiment also makes the abutment plate 6.2 detachably connected to the winding shell 6.1, that is, the abutment plate 6.2 can be replaced, which is convenient for cleaning and disinfection or directly replacing with a new one, which is conducive to the reuse of the winding assembly 6; wherein, the abutment plate 6.2 is detachably connected to the winding shell 6.1, and the detachable connection method can be a buckle clamping method, a screw screwing method, or other detachable methods.

[0047] The present invention further provides a locking block 7, which is detachably mounted on the traction belt 4 and abuts against the vertical plate 2 of the traction base plate 1 overlapped by the winding shell 6.1. The locking block 7 is installed on the traction belt 4 after the winding assembly 6 causes the traction belt 4 to drive the two traction base plates 1 to move toward the middle to a suitable position, so that the traction belt 4 maintains the two traction base plates 1 in a suitable position to maintain the current skin traction state. In this embodiment, preferably, the locking block 7 is a clip structure, and the two clamping surfaces of the clip structure have a clamping tooth structure or a fixed anti-slip structure in which a protrusion groove cooperates and is embedded, such as Figure 4 shown.

[0048] In the present invention, the traction base plate 1 and the traction extension plate 3 are both fixed to the skin, and then the skin is pulled under the traction of the traction belt 4. In this embodiment, it is preferred that a plurality of first through holes 10 are spaced apart on the traction base plate 1 and the traction extension plate 3, and the traction base plate 1 and the traction extension plate 3 are fixed to the skin by connecting to the skin after the skin needle punctures the first through holes 10. Of course, the traction base plate 1 and the traction extension plate 3 can also be fixed to the skin by pasting. Specifically, the wound repair traction device also includes an adhesive patch roll, which is composed of a double-sided adhesive patch. The length of the adhesive patch can be cut, and it can be pasted on the bottom surface of the traction base plate 1 or on the bottom surfaces of the traction base plate 1 and the traction extension plate 3 at the same time. That is, the adhesive patch is cut in time according to the use of the traction base plate 1 and the traction extension plate 3, so that the traction base plate 1 and the traction extension plate 3 thereon can be pasted with the adhesive patch. Furthermore, in order to facilitate the adaptation of the adhesive patch to the first through hole 10 on the traction base plate 1 and the traction extension plate 3, a second through hole is provided on the adhesive patch, and the second through hole is opposite to the first through hole 10 one by one when the adhesive patch is attached to the traction base plate 1 and / or the traction extension plate 3. The length of the traction base plate 1 is a multiple of the length of the traction extension plate 3. The first through hole 10 provided on the traction base plate 1 within the same length range as the traction extension plate 3 is opposite to the first through hole 10 on the traction extension plate 3 when the traction extension plate 3 is superimposed on the traction base plate 1 within this range. The adhesive patch on the adhesive patch roll has a dividing line, and the spacing between two adjacent dividing lines is the length of one traction extension plate 3. In this way, the dividing line position of the adhesive patch is determined according to the use of the traction extension plate 3, and the length of the adhesive patch cut along the dividing line is the required length, and when the adhesive patch is attached to the traction base plate 1, each second through hole thereon is opposite to each first through hole 10 one by one, which is convenient for use.

[0049] In this embodiment, the traction belt 4 is movably passed through the vertical plate 2, and is installed on the traction base plate 1 when in use. Specifically, a limit block 5 is arranged on the inactive end of the traction belt 4, and the limit block 5 abuts against the vertical plate 2 of a traction base plate 1 when the traction belt 4 is pulled. The traction base plate 1 is not the traction base plate 1 supported by the abutment plate 6.2. In order to more intuitively know the degree of skin pulling, the wound repair traction device also includes a pressure monitoring module, which includes a pressure sensor 8, a controller, a display and a power module. The pressure sensor 8 is detachably installed between the limit block 5 and the vertical plate 2 abutted by the limit block 5, and is connected to the controller. The controller is also connected to the display and the power module; the pressure sensor 8 can monitor the extrusion force between the limit block 5 and the vertical plate 2 during the pulling process, and the extrusion force value is transmitted to the display through the controller for display. By checking the extrusion force value displayed on the display, the degree of pulling can be known, which is convenient for medical staff to operate. Furthermore, the pressure sensor 8 can be detachably installed in a disposable protective bag 9. The disposable protective bag 9 has a third through hole for the traction belt 4 to pass through. When traction is required, the traction belt 4 is passed through the disposable protective bag 9 and then through the vertical plates 2 on the two traction base plates 1 in sequence. The disposable protective bag 9 causes the pressure sensor 8 to be set between the limit block 5 and the vertical plate 2, which can be abutted by the limit block 5 during traction, thereby realizing pressure monitoring. In addition, the provision of the disposable protective bag 9 not only facilitates the installation of the pressure sensor 8, but also facilitates the reuse of the pressure sensor 8. In addition, in order to facilitate the detection of the stability of the installation, the disposable protective bag 9 can also be connected to the limit block 5 or the vertical plate 2 by pasting. The pressure sensor 8 can be connected to the controller by wire or by wireless.

[0050] In addition, in order to improve the pulling effect of the traction extension plate 3 on the skin when in use, extended vertical plates 2 are installed on both sides of the traction extension plate 3 in the width direction, and the extended vertical plates 2 are penetrated by a traction reinforcement belt. The traction reinforcement belt is similar to the traction belt 4. It can cooperate with the upper limit block 5 and the locking block 7 to connect the corresponding two traction extension plates 3 together.

[0051] The use principle of the present invention is:

[0052] First, whether to use the traction extension plate 3 and the number of traction extension plates 3 to be used are selected according to the length of the wound. If the traction extension plate 3 is used, the traction extension plate 3 is first installed on the left and right sides of the traction base plate 1, and the two traction base plates 1 and the traction extension plates 3 thereon should correspond to each other one by one;

[0053] Secondly, the adhesive patch is attached as needed. If the traction base plate 1 and the traction extension plate 3 are only fixed to the skin by gluing, the adhesive patch of the corresponding length is glued to the bottom of the traction base plate 1 and the traction extension plate 3, and then the adhesive patch is used to fix them to the skin; if a skin needle is needed to fix them, the skin needle is passed through the first through hole 10 to fix the traction base plate 1 (traction extension plate 3) to the wound skin; of course, the skin needle and gluing can also be used at the same time; after fixation, the two traction base plates 1 are arranged on both sides of the wound, and each traction base plate 1 is fixed to the skin on the corresponding side of the wound;

[0054] Next, the movable end of the traction belt 4 is passed through the disposable protection bag 9, and then through the vertical plate 2 of a traction base plate 1, and the limit block 5 is brought close to the vertical plate 2. At this time, the disposable protection bag 9 is limited between the limit block 5 and the vertical plate 2, and the disposable protection bag 9 can be fixed on the limit block 5 or the vertical plate 2 by gluing; the movable end of the traction belt 4 then passes through the vertical plate 2 of another traction base plate 1, and then is inserted into the card slot on the winding card rod 6.5.2 through the card strip 4.1; the winding shaft cover plate 6.5.4 then covers the winding card rod 6.5.2 and the winding shaft 6.5.1, and the movable end of the traction belt 4 is fixed on the winding assembly 6;

[0055] The traction belt 4 is located between the two abutment plates 6.2.

[0056] Finally, the traction belt 4 outside the limit block 5 to the locking block 7 is cut at an appropriate position or the restriction on the winding shaft 6.5.1 and the winding clamping rod 6.5.2 is released by opening the winding shaft cover 6.5.4, and the traction belt 4 can be detached from the winding shaft rod 6.5. Before detachment, the abutment plate 6.2 can be separated from the winding shell 6.1 first; after removing the winding shell 6.1, the wound skin can be sutured and other operations can be performed according to the operation needs.

[0057] See also Figure 11-12In another embodiment of the present invention, considering that the belt surface of the traction belt 4 may be too large and hinder the medical staff from treating the wound surface, the traction belt of this embodiment can be retracted to reduce the area. The specific structure is: a sliding opening is provided on the limit block 5, and a sliding rod 5.1 is provided at the sliding opening; an annular surface is provided at one end of the traction belt 4, and the one end is slidably connected to the limit block 4 by being sleeved on the sliding rod 5.1 through the annular surface, and the belt surface of the traction belt 4 passes through the sliding opening on the limit block 5, such as Fig.12 As shown; in this way, the belt surface of the traction belt 4 can be folded by sliding the traction belt 4, and then matched with the locking member 7 that can clamp and fix the folded belt surface of the traction belt 4, the traction belt 4 can be stably folded and maintained in the pulling state, that is, the folding action of the traction belt 4 of this embodiment is folded after the traction is completed, and the structure after folding is as shown Fig.11 shown.

[0058] The above description is a detailed description of the preferred feasible embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modified changes completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
