[0042] The purpose of the utility model is to provide a tool for folding a sheet structure, which can be used to pre-fold the medical film material, and then manually knead the medical film material according to the crease formed during pre-folding, so as to complete the folding of the medical film material, thereby improving the folding efficiency of the medical film material, improving the dimensional stability of the medical film material after folding, and reducing the scrapping of the medical film material due to excessive deviation of the folded size of the medical film material.

[0043] In order to make the purpose, advantages and features of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model. The same or similar reference numerals in the drawings represent the same or similar components.

[0044] Please refer to Figures 1 to 5 The tool 10 provided in one embodiment of the utility model includes a first component 11 and a second component 12. By using the cooperation between the first component 11 and the second component 12, the following can be performed: Figure 6 The uterine cavity anti-adhesion membrane 1 (i.e. the aforementioned medical membrane material) is pre-folded so that the uterine cavity anti-adhesion membrane 1 is in the following Figure 7 and Figure 8 The semi-folded state is shown, and then the operator manually pinches the intrauterine anti-adhesion membrane 1 so that the intrauterine anti-adhesion membrane 1 is formed into a sheet structure, completing the folding of the intrauterine anti-adhesion membrane 1.

[0045] Specifically, please refer to Figure 1 and Figure 2 The first component 11 includes a first base 100 and a pressure column 200. The first base 100 includes a first surface 110. In this embodiment, the first surface 110 is the bottom surface of the first base 100 (eg Figure 1 The pressure column 200 is disposed on the first surface 110 of the first base 100 and extends in a direction perpendicular to the first surface 110. The pressure column 200 is formed with a plurality of first ridges 210 arranged in sequence at one end away from the first base 100, and each of the first ridges 210 extends in a direction parallel to the first surface. In the figure, the Z direction represents the direction perpendicular to the first surface 110, the X direction represents the arrangement direction of the plurality of first ridges 210, and the Y direction represents the extension direction of each of the first ridges 210. Preferably, as Figure 2As shown, the first ridges are parallel to each other. A person skilled in the art will appreciate that the first ridges may not be parallel to each other, and are specifically arranged according to the shape to be folded.

[0046] Furthermore, at one end of the pressure column 200 away from the first base 100, a plurality of first folding planes 201 are arranged at an angle to the first surface 110. The plurality of first folding planes 201 are connected in sequence, and at the end away from the first surface 110, two adjacent first folding planes 201 intersect to form the first convex ridge 210.

[0047] In other words, in the arrangement direction of the plurality of first ribs 210, the distance between the two first folding planes 201 constituting the same first rib 210 gradually decreases to zero in the direction away from the first base 100, so that the shape of the first rib 210 in the cross section perpendicular to the first surface 110 is a triangle, and the vertex angle of the triangle is located at the end of the first rib 210 away from the first base 100. The vertex angle of the triangle is the angle between the two first folding planes 201 constituting the same first rib 210.

[0048] Those skilled in the art can understand that, at the end of the pressure column 200 away from the first base 100, in addition to the first convex rib 210, a first concave rib 220 is formed between two adjacent first convex ribs 210, and the first concave rib 220 is formed by the intersection of one end of two adjacent first folding planes 201 close to the first surface 110. Thus, one first convex rib 210 and one first concave rib 220 are formed on both sides of each first folding plane 201, and one first convex rib 210 or one first concave rib 220 is formed between two adjacent first folding planes 201. The first convex rib 210 and the first concave rib 220 are arranged alternately, and the number of the first convex rib 210 is one more than the number of the first concave rib 220. The first folding plane 201, the first convex rib 210, and the first concave rib 220 are all used to form a structure for folding the intrauterine anti-adhesion membrane 1.

[0049] Please refer to Figure 3 and Figure 4The second component 12 includes a second base 300, and the second base 300 includes a second surface 310. In this embodiment, the second surface 310 is the upper surface of the second base 300. When in use, the second base 300 is opposite to the first base 100, so that the second surface 310 is arranged face to face with the first surface 110. A recessed area is provided on the second surface 310, and a plurality of second folding planes (not marked in the figure) connected in sequence are formed in the recessed area, and each of the second folding planes is arranged at an angle with the second surface 310. In addition, the angle between each of the second folding planes and the second surface is respectively consistent with the angle between the first folding plane 201 corresponding thereto and the first surface 110; the width of each of the second folding planes is the same as the width of the first folding plane 201 corresponding thereto.

[0050] At one end away from the second surface 310, two adjacent second folding planes intersect to form a second concave ridge 311. At one end close to the second surface 310, two adjacent second folding planes intersect to form a second convex ridge (not marked in the figure). The second convex ridges and the second concave ridges 311 are arranged alternately, each second convex ridge is located between two adjacent second concave ridges 311, and the number of the second concave ridges 311 is one more than the number of the second convex ridges. When in use, each second concave ridge 311 corresponds to a first convex ridge 210 of the first base 100 and is used to accommodate the corresponding first convex ridge 210, each second convex ridge corresponds to a first concave ridge 220 of the first base 100 and is used to be accommodated in the corresponding first concave ridge 220, and each second folding plane corresponds to a first folding plane 201 of the first base 100. Thus, the first base 100 and the second base 300 work together to fold the intrauterine anti-adhesion membrane 1 and form a crease at a position of the intrauterine anti-adhesion membrane 1 corresponding to the intersection line of two adjacent first folding planes 201 or corresponding to the intersection line of two adjacent second folding planes.

[0051] Specifically, when the tool 10 is used to pre-fold the intrauterine anti-adhesion membrane 1, the intrauterine anti-adhesion membrane 1 is first placed on the second surface 310 of the second base 300 and aligned with the recessed area. Afterwards, when the pressure column 200 is aligned with the recessed area, the first base 100 is driven to move in a direction perpendicular to the first surface 110 and approach the second base 300 in any appropriate manner until each of the first ridges 210 on the pressure column 200 is pressed into the corresponding sub-recessed area 311. In this process, all of the first ridges 210 also press the intrauterine anti-adhesion membrane 1 into the recessed area, so that the intrauterine anti-adhesion membrane 1 is folded. Then the first component 11 is separated from the second component 12, and the intrauterine anti-adhesion membrane 1 is taken out to obtain the intrauterine anti-adhesion membrane 1 in a semi-folded state, and multiple folds are formed on the intrauterine anti-adhesion membrane 1 in a semi-folded state. Afterwards, the operator can manually complete the folding of the intrauterine anti-adhesion membrane 1 along the crease. Since the size of the pressure column 200 and the recessed area is constant, when the intrauterine anti-adhesion membrane 1 is pre-folded using the tool 10, the stability of the folding size of the intrauterine anti-adhesion membrane 1 can be effectively guaranteed, thereby ensuring the size stability of the intrauterine anti-adhesion membrane 1 after being fully folded. In addition, after the intrauterine anti-adhesion membrane 1 is pre-folded using the tool 10, the difficulty of the operator performing subsequent folding operations is also reduced, and the folding efficiency is improved. Not only that, compared with the traditional folding method that folds the intrauterine anti-adhesion membrane 1 into a columnar structure and causes the overall bending deformation of the intrauterine anti-adhesion membrane 1, the folding method of the embodiment of the utility model enables the intrauterine anti-adhesion membrane 1 to be folded into a sheet structure, and the deformation amount of the intrauterine anti-adhesion membrane 1 is smaller and the degree of damage is lower, so when the intrauterine anti-adhesion membrane 1 is delivered to the uterine cavity, it is easier to unfold.

[0052] In the embodiment of the utility model, the number of the first folding planes 201 is 2m-1, and the number of the first ridges 210 is m. Among them, 2m-2 first folding planes 201 form m-1 first ridges 210, and one of the first folding planes 201 close to the side plane of the pressure column 200 intersects with the side plane of the pressure column 200 to form another first ridge 210. Preferably, the plurality of first ridges 210 are arranged in sequence, and the extension direction of each first ridge 210 is parallel to the first surface 110. The plurality of first ridges 210 are numbered along the arrangement direction of the plurality of first ridges 210, namely the first first ridge 210, the second first ridge 210...the m-1th first ridge 210, the mth first ridge 210, and m is the number of the first ridges 210, which is an odd number greater than 1. The first ridge 210 is located in the middle. In the direction perpendicular to the first surface 110, the first The distance between the first ridge 210 and the first surface 110 is the largest, and the distances between the remaining first ridges 210 and the first surface 110 are the largest. The first ridges 210 decrease in size in sequence toward the first ridge 210 or the mth ridge 210 at the end. The first convex ribs 210 are respectively oriented toward the first first convex rib 210 and the mth first convex rib 210 located at the end, and the mth first convex rib 210 is oriented toward the first first convex rib 210 and the mth first convex rib 210 located at the end. The first ridges 210 first contact the intrauterine anti-adhesion membrane 1, so that the middle area of ​​the intrauterine anti-adhesion membrane 1 is stressed and folded first, and the other first ridges 210 contact the intrauterine anti-adhesion membrane 1 in sequence, thereby making the intrauterine anti-adhesion membrane 1 stressed from the middle area to the side areas in sequence, and the middle area is stressed and folded in sequence, that is, the intrauterine anti-adhesion membrane 1 is folded in the order from the middle to the sides, which can avoid the situation that the side areas of the intrauterine anti-adhesion membrane 1 are folded before the middle area, causing the middle area to be pulled and broken. In addition, the distance between the first ridge 210 and the first surface 110 refers to the distance from the intersection of the two planes constituting the first ridge 210 to the first surface 110. Except for the mth first ridge 210, the two planes constituting the other first ridges 210 refer to two adjacent first folding planes 201. For the mth first ridge 210, the two planes constituting the first ridge 210 refer to a first folding plane 201 close to the side plane of the pressure column 200 and the side plane of the pressure column 200.

[0053] The hardness of the uterine cavity anti-adhesion membrane 1 in the prior art is relatively high. The angle between two adjacent first folding planes 201 of the first convex ridge 210 is the smallest. The first ridge 210 is directed toward the first ridge 210 on both sides, and the angle between the adjacent two planes of the remaining first ridge 210 is formed along the direction away from the first ridge 210. In this way, the force applied to the intrauterine anti-adhesion membrane 1 is reduced from the middle to the two sides, which is conducive to folding the intrauterine anti-adhesion membrane 1 in the order from the middle to the two sides.

[0054] For the first folding plane 201, Figure 1 and Figure 2As shown in the figure, 2m-1 first folding planes 201 are located at the end of the pressure column 200 away from the first base 100 and are connected in sequence, and each first folding plane 201 is at an angle to the first surface 110. Figure 1 The first folding planes 201 are numbered in the order from left to right (shown), for example, the first first folding plane 201, the second first folding plane 201, the third first folding plane 201, ... the 2m-2th first folding plane 201, the 2m-1th first folding plane 201. Among them, the first first folding plane 201 intersects with the second first folding plane 201 to form the first first ridge 210, the third first folding plane 201 and the fourth first folding plane 201 intersect to form the second first ridge 210, ..., the 2m-3th first folding plane 201 intersects with the 2m-2th first folding plane 201 to form the m-1th first ridge 210, and the 2m-1th first folding plane 201 intersects with the side surface of the pressure column 200 to form the mth first ridge 210. That is, the nth first folding plane 201 intersects with the n+1th first folding plane 201 to form a first ridge 210, where n is an odd number greater than or equal to 1 and less than 2m-1. Also, the last first folding plane 201 intersects with the side surface of the pressure column 200 to form a first ridge 210. In other words, except for the mth first ridge 210, the two planes constituting the other first ridges 210 are both the first folding planes 201, and one of the two planes constituting the mth first ridge 210 is the first folding plane 201, and the other is the side plane of the pressure column 200.

[0055] Further, the first first concave ridge 220 is formed between the first first convex ridge 210 and the second first convex ridge 210, the second first concave ridge 220 is formed between the second first convex ridge 210 and the third first convex ridge 210… the m-1th first concave ridge 220 is formed between the m-1th first convex ridge 210 and the mth first convex ridge 210.

[0056] at the same time, Figure 3 The recessed area of ​​the second base 300 shown in the figure has 2m-1 second folding planes formed therein, and the number of the first folding planes 201 of the pressure column is the same as the number of the second folding planes of the base 300 .

[0057] According to the arrangement order of the plurality of second folding planes, the first second folding plane intersects with the second second folding plane to form the first second concave ridge 311, the third second folding plane intersects with the fourth second folding plane to form the second second concave ridge 311...the 2m-3th second folding plane intersects with the 2m-2th second folding plane to form the m-1th second concave ridge 311, the 2m-1th folding plane intersects with the side wall of the recessed area to form the mth second concave ridge 311. The first second convex ridge is formed between the first second concave ridge 311 and the second second concave ridge 311, the second second convex ridge is formed between the second second concave ridge 311 and the third second concave ridge 311...the m-1th second convex ridge is formed between the m-1th second concave ridge 311 and the mth second concave ridge 311.

[0058] When the tool 1 pre-folds the intrauterine anti-adhesion membrane 1, the intrauterine anti-adhesion membrane 1 forms a fold at the position corresponding to the connection between two adjacent first folding planes 201. Specifically, the intrauterine anti-adhesion membrane 1 forms the first fold at the position corresponding to the intersection of the first first folding plane 201 and the second first folding plane 201, forms the second fold at the position corresponding to the intersection of the second first folding plane 201 and the third first folding plane 201, ... forms the 2m-3 fold at the position corresponding to the intersection of the 2m-3 first folding plane 201 and the 2m-2 first folding plane 201, and forms the 2m-2 fold at the position corresponding to the intersection of the 2m-2 first folding plane 201 and the 2m-1 first folding plane 201. The 2m-2 folds divide the intrauterine anti-adhesion membrane 1 into 2m-1 sub-regions, each of which corresponds to one first folding plane 201. Moreover, the mth sub-region and the m+1th sub-region correspond to the The first ridge 210, in other words, the central area of ​​the intrauterine anti-adhesion membrane 1 mentioned in this article refers to the mth sub-area and the m+1th sub-area, one side area refers to the 1st sub-area to the m-1th sub-area, and the other side area refers to the m+2th sub-area to the 2m-1th sub-area.

[0059] In an alternative embodiment, the end surface of the pressure column away from the first base includes 2m first folding planes connected in sequence, and two adjacent first folding planes limit a first convex edge. That is, according to the arrangement order of the plurality of first folding planes (in Figure 1The folding planes are numbered as the 1st first folding plane, the 2nd first folding plane, the 3rd first folding plane, ... the 2m-1st first folding plane, the 2m-1st first folding plane, respectively, in the order from left to right. Among them, the 1st first folding plane and the 2nd first folding plane jointly define the 1st first ridge, the 3rd first folding plane and the 4th first folding plane jointly define the 2nd first ridge, ..., the 2m-1st first folding plane and the 2m-th first folding plane define the mth first ridge (not shown in the figure). That is, the nth first folding plane and the n+1th first folding plane jointly define one first ridge, and n is an odd number greater than or equal to 1 and less than 2m-1.

[0060] Correspondingly, the intrauterine anti-adhesion membrane forms the first fold at the position corresponding to the intersection of the first first folding plane and the second first folding plane, forms the second fold at the position corresponding to the intersection of the second first folding plane and the third first folding plane, ... forms the 2m-2 fold at the position corresponding to the intersection of the 2m-4 first folding plane and the 2m-1 first folding plane, and forms the 2m-1 fold at the position corresponding to the intersection of the 2m-1 first folding plane and the 2m-1 first folding plane. The 2m-1 folds divide the intrauterine anti-adhesion membrane 1 into 2m sub-regions, each of which corresponds to one of the first folding planes. Moreover, the m-th sub-region and the m+1-th sub-region correspond to the m-4-th first folding plane and the 2m-1-th first folding plane. In other words, the middle area of ​​the intrauterine anti-adhesion membrane 1 mentioned in this article refers to the mth sub-area and the m+1th sub-area, one side area refers to the 1st sub-area to the m-1th sub-area, and the other side area refers to the m+2th sub-area to the 2mth sub-area.

[0061] The width w of all the first folding planes 201 (eg Figure 1 As shown in FIG. 1 , the first surface 110 is equal to the first surface 110. The distance between the first ridge 210 and the first surface 110 is the largest, and the distances between the remaining first ridges 210 and the first surface 110 are the largest. On the premise that the direction of the first ridge 210 to the first ridge 210 or the mth ridge 210 decreases in sequence, the first ridge 210 is also realized. The included angle between the two first folding planes 201 of the first convex rib 210 is the smallest, and the included angle between the two first folding planes 201 of the remaining first convex ribs 210 is along the first The effect of increasing the direction from the first ridge 210 to the first ridge 210 or the mth first ridge 210 is achieved.

[0062] The width w of each first folding plane 201 is equal, resulting in that the sizes of the two side regions of the intrauterine anti-adhesion membrane 1 in the planar unfolded state in the arrangement direction of the plurality of first ridges 210 are not equal, specifically, in the arrangement direction of the plurality of first ridges 210, the size of the side region where the m-1th sub-region is located is greater than the size of the side region where the m+2th sub-region is located. The angle between the two first folding planes 201 of the first ridge 210 is greater than the angle between the two first folding planes 201 of the first ridge 210. The angle i between the two planes of the first convex ridge 210 is an odd number greater than or equal to 1, which makes the first convex ridge 210 The distance between the first ridge 210 and the first surface 110 is less than The distance from the first convex ridge 210 to the first surface 110 is reduced. This is conducive to the smooth folding of the intrauterine adhesion film 1 from the middle to the sides, reducing the possibility of the intrauterine adhesion film 1 being broken during the folding process. It can be understood that when When it is less than m, it constitutes the The two planes of the first convex rib 210 are the two first folding planes 201. When it is equal to m, it constitutes the One of the two planes of the first convex ridge 210 is the first folding plane 201 , and the other is the side plane of the pressing column 200 .

[0063] In practice, according to the size of the intrauterine anti-adhesion membrane 1, the number of the first folding planes 201 is five, wherein the first first folding plane 201 and the second first folding plane 201 jointly define the first first ridge 210, the third first folding plane 201 and the fourth first folding plane 201 jointly define the second first ridge 210, and the fifth first folding plane 201 and the side of the pressure column 200 jointly define the third first ridge 210. Here, the angle between the two first folding planes 201 constituting the second first rib 210 is greater than the angle between the two first folding planes 201 constituting the first first rib 210, and is also greater than the angle between the first folding plane 201 constituting the third first rib 210 and the side plane of the pressure column 200. Four folds and five sub-regions are formed on the intrauterine anti-adhesion membrane 1 pre-folded by the tool 10, wherein the third sub-region and the fourth sub-region constitute the middle region, the first sub-region and the second sub-region constitute a side region, and the fifth sub-region constitutes another side region. That is, the number of the first folding planes 201 is 2m-1, and m is equal to 3.

[0064] Furthermore, the width w of each first folding plane 201 is 3 mm to 5 mm. Matchingly, the angle between the two first folding planes 201 constituting the first first convex ridge 210 is 100° to 130°, the angle between the two first folding planes 201 constituting the second first convex ridge 210 is 30° to 60°, and the angle between the first folding plane 201 constituting the third first convex ridge 210 and the side plane of the pressure column 200 is 40° to 80°.

[0065] Preferably, the intersection of two adjacent first folding planes 201 is formed into a rounded corner, and the intersection of the first folding plane 201 and the side wall of the pressure column 200 is also formed into a rounded corner, so that the first convex edge 210 and the first concave edge 220 do not form a sharp structure. Similarly, the intersection of two adjacent second folding planes is formed into a rounded corner, and the intersection of the second folding plane and the side plane of the recessed area is also formed into a rounded corner, so that the second convex edge and the second concave edge 311 do not have a sharp structure, thereby preventing the intrauterine anti-adhesion membrane 1 from being scratched during the folding process. Optionally, the radius R of the fillet can be selected in the range of 0.3mm to 0.8mm.

[0066] Optionally, the first base 100 is provided with a first guide portion, and the second base 300 is provided with a second guide portion, and the second guide portion cooperates with the first guide portion so that the first base 100 moves along a direction perpendicular to the first surface 110, so as to ensure that each of the first ridges 210 of the pressure column 200 can be pressed into the corresponding sub-recessed area 311 to avoid misalignment. The embodiment of the utility model does not particularly limit the specific forms of the first guide portion and the second guide portion. In an optional implementation, as Figure 2 As shown, the first guide portion includes a guide through hole 101 penetrating the first base 100 in a direction perpendicular to the first surface 110. Figure 3 As shown, the second guide portion includes a guide post 400 disposed on the second surface 310 and extending in a direction perpendicular to the first surface 110. During operation, one guide post 400 is inserted into one guide through hole 101. In an alternative implementation, a guide post extending in a direction perpendicular to the first surface 110 is disposed on the first surface of the first base, and a guide hole (not shown in the figure) extending through the first surface 110 is disposed on the second base.

[0067] Optionally, a limiting groove is also formed on the second surface 310. The limiting groove includes a first sub-limiting groove 312 and a second sub-limiting groove 313, and the first sub-limiting groove 312 and the second sub-limiting groove 313 are distributed on opposite sides of the recessed area in a direction perpendicular to the first surface 110, and the first sub-limiting groove 312 and the second sub-limiting groove 313 are both connected to the recessed area. The contour of the limiting groove matches the shape of the intrauterine anti-adhesion membrane 1, and the area of ​​the area defined by the contour of the limiting groove is 1.1 to 1.2 times the area of ​​the intrauterine anti-adhesion membrane 1. It can be understood that the recessed area is at least partially within the area defined by the contour of the limiting groove. When the intrauterine anti-adhesion membrane 1 is placed on the second base 300 , the intrauterine anti-adhesion membrane 1 is actually placed within the range defined by the limiting groove to ensure that the intrauterine anti-adhesion membrane 1 is located in the recessed area and can be folded by the force from the pressure column 200 .

[0068] Furthermore, the present invention also provides a folding device, such as Figure 5As shown, the folding device includes a press machine 20 and the aforementioned tooling 10. The press machine 20 includes a driving mechanism 21, a joining platform 22 and a carrying platform 23. The driving mechanism 21 is connected to the joining platform 22, and is used to drive the joining platform 22 to make reciprocating linear motion in a direction perpendicular to the first surface 110. The carrying platform 23 and the joining platform 22 are arranged in a direction perpendicular to the first surface 110. The first base 100 of the tooling 10 is connected to the joining platform 22, and the second base 300 of the tooling 10 is connected to the carrying platform 23, so that the second surface 310 is arranged face to face with the first surface 110. In this way, the driving mechanism 21 can be used to drive the first base 100 to move in a direction perpendicular to the first surface 110.

[0069] It can be understood that one pressing machine 20 can cooperate with a plurality of the toolings 10 to pre-fold a plurality of the intrauterine anti-adhesion membranes 1 at the same time.

In one implementation, the bonding platform 22 and the bearing platform 23 are made of ferromagnetic materials, and the first base 100 and the second base 300 are made of permanent magnets. In this way, there is no need to add an additional mechanical connection mechanism, and the assembly operation of the tooling 10 and the pressing machine 20 is also simplified.

[0071] Further, the press machine 20 also includes an electric heating mechanism 24, which is connected to the joint platform 22. The electric heating mechanism 24 generates heat when powered on, and the heat is conducted to the pressure column 200 through the first base 100, and further conducted to the uterine cavity anti-adhesion membrane 1, so as to soften and thermoplasticize the uterine cavity anti-adhesion membrane 1, so that the uterine cavity anti-adhesion membrane 1 is easier to fold, and maintains the folded shape, which is convenient for subsequent loading to the delivery device. It should be understood that the press machine 20 also includes a control mechanism (not shown) and an operation panel 25, and the control mechanism is connected to the operation panel 25, the electric heating mechanism 24 and the drive mechanism 21.
