Description

Technical Field

[0001] The present invention relates to the field of interventional medicine, and particularly to a gasket cutting system. Background Art

[0002] The interventional treatment method for treating vascular diseases has the characteristics of low cost, short treatment cycle and small trauma to the human body, and thus has gradually become the mainstream method for treating vascular diseases. In interventional treatment, a delivery sheath is usually required to establish a channel, and then a corresponding guide wire is inserted as needed to serve as an entry track for other instruments, such as a guiding catheter, a balloon catheter or other endovascular devices. When the delivery sheath enters the human blood vessel, due to blood pressure, there is a tendency for blood to overflow from the body of the delivery sheath. At this time, the delivery sheath needs to be provided with a corresponding sealing gasket structure.

[0003] And a thin slit usually needs to be cut out on the sealing gasket for the instrument to pass through, so as to ensure the sealing performance of the sealing gasket as much as possible. However, the existing method of cutting the slit is to manually cut each sealing gasket with a scalpel. This cutting method has low efficiency, high time cost and high labor cost, and the depth, length, etc. of the slit cannot be accurately controlled, so the sealing performance of the sealing gasket cannot be guaranteed. At the same time, a slit with a better sealing shape cannot be cut out. Summary of the Invention

[0004] To overcome the problems existing in the prior art, the present invention provides a gasket cutting system.

[0005] The solution for the present invention to solve the technical problem is to provide a gasket cutting system, which includes a cutting device and a sealing gasket. The cutting device includes a cutting table, a pressing member and a tool assembly. A receiving groove for receiving the sealing gasket is provided on the cutting table. The tool assembly can move on the cutting table, and when the tool assembly moves, it can pass through the receiving groove. An opening window is provided on the pressing member, which penetrates from the side far away from the sealing gasket to the side close to the sealing gasket. After the sealing gasket is received in the receiving groove, the pressing member is pressed on the sealing gasket. The sealing gasket deforms under the extrusion of the pressing member, and a part of the sealing gasket enters the opening window. When the tool assembly moves through the receiving groove, the part of the sealing gasket located in the opening window is cut by the tool assembly to form a slit. The two ends of the slit are arc-shaped towards the center position, and the depth of the slit gradually becomes deeper from the two ends towards the center position.

[0006] In some embodiments of the present invention, one surface of the accommodation groove in contact with the sealing gasket protrudes towards the sealing gasket to form a first arc structure, and one surface of the pressing member in contact with the sealing gasket is recessed away from the sealing gasket to form a second arc structure. After the pressing member covers the sealing gasket, the sealing gasket is extruded by the first arc structure and the second arc structure and deforms into an arc shape.

[0007] In some embodiments of the present invention, a slide rail protrudes on one surface of the cutting table, the accommodation groove is arranged on the slide rail, the tool assembly includes a sliding member, and a chute is arranged on the sliding member, and the chute cooperates with the slide rail.

[0008] In some embodiments of the present invention, the tool assembly further includes a tool and a tool fixing member. A tool receiving groove penetrating from a surface away from the chute to a surface close to the chute is arranged on the sliding member. A fixing member receiving groove is arranged on an adjacent surface of the surface of the sliding member away from the chute, and the fixing member receiving groove is communicated with the tool receiving groove. The tool is received in the tool receiving groove, and after the fixing member is received in the fixing member receiving groove, the fixing member can fix the tool.

[0009] In some embodiments of the present invention, a first cutting groove is arranged on the slide rail, and a second cutting groove is arranged on a surface of the pressing member away from the accommodation groove. The first cutting groove passes through the accommodation groove and is communicated with the second cutting groove. The cutting head of the tool can slide in the first cutting groove and the second cutting groove; the distance from the first cutting groove to the surface of the cutting table away from the accommodation groove is less than the distance from the surface of the sealing gasket close to the pressing member to the surface of the cutting table away from the accommodation groove, and the distance from the second cutting groove to the surface of the cutting table away from the accommodation groove is less than the distance from the surface of the sealing gasket close to the pressing member to the surface of the cutting table away from the accommodation groove.

[0010] In some embodiments of the present invention, the cutting device further includes an ejecting member. The ejecting member includes a body and a rotating shaft. The body includes a button portion, a connecting portion, and an ejecting portion. One end of the connecting portion is connected to the ejecting portion, and the other end is connected to the button portion. The rotating shaft is arranged on the connecting portion, and the body can rotate around the rotating shaft.

[0011] In some embodiments of the present invention, an ejector member receiving groove is provided on a side of the cutting table away from the receiving groove. The ejector member is received in the ejector member receiving groove. The ejecting portion is disposed close to the receiving groove. The cutting table is provided with a first through groove penetrating through the receiving groove and the ejector member receiving groove. A second through groove is provided at a position of the cutting table corresponding to the key portion, which penetrates from a surface of the cutting table away from the ejector member to the ejector member receiving groove.

[0012] In some embodiments of the present invention, a ejector pin protruding relative to the ejecting portion is provided on the ejecting portion. The ejector pin is received in the first through groove. The key portion extends into the second through groove and is exposed outside the cutting table.

[0013] In some embodiments of the present invention, the cutting device further includes a drive system. The drive system includes a power source and a drive connecting member. The drive system is connected to the tool assembly through the drive connecting member. The power source can drive the drive connecting member to move, and the movement of the drive connecting member drives the tool assembly to move.

[0014] In some embodiments of the present invention, the drive system further includes a reciprocating lead screw. The reciprocating lead screw is arranged parallel to the slide rail. The drive connecting member is sleeved on the reciprocating lead screw, and the drive connecting member is threadedly connected to the reciprocating lead screw. The power source is connected to an end of the reciprocating lead screw. The power source can drive the reciprocating lead screw to rotate, and the rotation of the reciprocating lead screw drives the drive connecting member to move on the reciprocating lead screw along the axial direction of the reciprocating lead screw.

[0015] Compared with the prior art, a gasket cutting system of the present invention has the following advantages: The cut formed by the cutting device of the present invention has an arc-shaped structure. The arc-shaped cut has better sealing performance compared to a straight cut or a cut of other shapes. When an instrument passes through the cut, a position with a deeper cut depth will be more strongly squeezed by the instrument, and the position with a deeper cut depth will fit the instrument more tightly, thereby further ensuring the sealing performance of the sealing gasket. At the same time, in a specific embodiment of the present invention, when cutting the cut, only by sliding the tool assembly on the cutting table, the operation of completely cutting the cut can be completed. The operation is very simple, time-saving and labor-saving, reducing the time cost and labor cost. At the same time, the cuts formed after cutting the sealing gasket with the cutting device can be highly unified in terms of size and shape. The size and shape of each cut can be accurately controlled, thereby ensuring the sealing performance of each sealing gasket and improving the yield rate of the sealing gasket.

[0033] Please refer to Figure 1 - Figure 3, an embodiment of the present invention provides a gasket cutting system 100. The gasket cutting system 100 includes a cutting device 1 and a sealing gasket 2. The sealing gasket 2 is particularly suitable for use in a delivery sheath to provide sealing performance for the delivery sheath, and the delivery sheath is used to establish a delivery channel from outside the body to inside the body. The cutting device 1 is used to cut a slit 21 in the sealing gasket 2. The slit 21 allows an instrument to pass through the sealing gasket 2 while ensuring the sealing performance of the sealing gasket 2. The cutting device 1 includes a cutting table 11, a pressing member 12, and a tool assembly 13. A receiving groove 111 for receiving the sealing gasket 2 is provided on the cutting table 11. The tool assembly 13 can move on the cutting table 11, and when the tool assembly 13 moves, it can pass through the receiving groove 111, thereby cutting the sealing gasket 2 received in the receiving groove 111. An opening window 121 that penetrates from a surface away from the sealing gasket 2 to a surface close to the sealing gasket 2 is provided on the pressing member 12. After the sealing gasket 2 is received in the receiving groove 111, the pressing member 12 is pressed on the sealing gasket 2. The sealing gasket 2 deforms under the extrusion of the pressing member 12, and part of the sealing gasket 2 will be extruded and deformed and then enter the opening window 121. When the tool assembly 13 moves through the receiving groove 111, the part of the sealing gasket 2 located in the opening window 121 is cut by the tool assembly 13 to form a slit 21. Both ends of the slit 21 are arc-shaped and transition towards the central position, and the depth H of the slit 21 gradually becomes deeper from both ends towards the central position.

[0034] Specifically, in a specific embodiment of the invention, the sealing gasket 2 is made of an elastic material, such as silicone. When the sealing gasket 2 needs to be cut, the sealing gasket 2 is placed in the receiving groove 111, and then the pressing member 12 is pressed on the sealing gasket 2. The pressing member 12 can press the sealing gasket 2 to prevent the sealing gasket 2 from shifting in the receiving groove 111. At the same time, after the pressing member 12 is pressed on the sealing gasket 2, the sealing gasket 2 will deform, and part of the sealing gasket 2 will be squeezed into the opening window 121. At this time, the part of the sealing gasket 2 that enters the opening window 121 will be squeezed and bent to form a certain arc shape. When the tool assembly 13 passes through the receiving groove 111, the tool assembly 13 will also pass through the pressing member 12 and then cut the part of the sealing gasket 2 located in the opening window 121, and the tool assembly 13 cuts from one side of the sealing gasket 2 to the other side. Since the part of the sealing gasket 2 located in the opening window 121 is in an arc shape, and the movement trajectory of the tool assembly 13 is a straight line, the depth H of the cut seam 21 formed by the tool assembly 13 gradually becomes deeper from both ends to the central position, and the two ends of this cut seam 21 arc towards the central position to form an arc-shaped cut seam 21. It can be understood that the shape of the cut seam 21 formed by cutting with the cutting device 1 of the present invention is an arc structure, and the arc-shaped cut seam 21 has good sealing performance compared with a straight cut seam or other shaped cut seams. When the instrument passes through the cut seam 21, the position with a deeper depth of the cut seam 21 will be more strongly squeezed by the instrument, and the position with a deeper depth of the cut seam 21 will fit the instrument more tightly, thereby further ensuring the sealing performance of the sealing gasket 2. At the same time, if the sealing gasket is to be cut manually to form an arc-shaped cut seam and ensure the size and shape of each cut seam, the difficulty will be very great. In the specific embodiment of the present invention, when cutting the cut seam 21, only the tool assembly 13 needs to be slid on the cutting table 11 to complete the operation of cutting the cut seam 21. The operation is very simple, time-saving and labor-saving, reducing the time cost and labor cost. At the same time, the cut seam 21 formed by cutting the sealing gasket 2 with the cutting device 1 can be highly unified in size and shape, and the size and shape of each cut seam 21 can be accurately controlled, thereby ensuring the sealing performance of each sealing gasket 2 and improving the yield rate of the sealing gasket 2.

[0035] Please refer to Figure 1 , Figure 3 - Figure 5, to further ensure that the shape of the slit 21 is an arc-shaped slit, a first arc-shaped structure 1111 is formed by protruding from the surface of the accommodation groove 111 in contact with the sealing gasket 2 toward the sealing gasket 2, and a second arc-shaped structure 122 is formed by recessing from the surface of the pressing member 12 in contact with the sealing gasket 2 away from the sealing gasket. After the pressing member 12 covers the sealing gasket 2, the sealing gasket 2 is deformed into an arc shape under the extrusion of the first arc-shaped structure 1111 and the second arc-shaped structure 122. It can be understood that in a specific embodiment of the present invention, the curvature of the first arc-shaped structure 1111 is similar to the curvature of the second arc-shaped structure 122. Thus, when the pressing member 12 presses on the sealing gasket 2, the sealing gasket 2 can be deformed in accordance with the shapes of the first arc-shaped structure 1111 and the second arc-shaped structure 122, so that the sealing gasket 2 is deformed into an arc shape similar to the first arc-shaped structure 1111 and the second arc-shaped structure 122. At this time, the sealing gasket 2 has been deformed into an arc shape. When the tool assembly 13 passes through the pressing member 12 and cuts a part of the sealing gasket 2 within the opening 121, a slit 21 with an arc shape whose depth gradually becomes deeper from both ends to the central position is inevitably formed. Therefore, the first arc-shaped structure 1111 and the second arc-shaped structure 122 can ensure that the shape of the slit 21 is an arc.

[0036] In a specific embodiment of the present invention, the number of the accommodation grooves 111 and the pressing members 12 is multiple. The multiple accommodation grooves 111 are arranged side by side, and the multiple accommodation grooves 111 are arranged on the same straight line, and this straight line is parallel to the movement trajectory of the tool assembly 13, as Figure 1 shown. When the tool assembly 13 moves, it can pass through the multiple accommodation grooves 111, and then cut the multiple sealing gaskets 2. In other specific embodiments of the present invention, the number of the accommodation grooves 111 can be set correspondingly according to actual needs, such as specifically setting 3, 6, 8, etc. accommodation grooves 111.

[0037] Further, please refer to Figure 1 , Figure 6 and Figure 7, a slide rail 112 protrudes on one side of the cutting table 11, the accommodating groove 111 is arranged on the slide rail 112, the tool assembly 13 includes a sliding member 131, a chute 1311 is arranged on the sliding member 131, and the chute 1311 cooperates with the slide rail 112, so that the sliding member 131 can slide on the slide rail 112. Since the accommodating groove 111 is arranged on the slide rail 112, when the sliding member 131 moves on the slide rail 112, it will pass through the accommodating groove 111 located on the slide rail 112. At the same time, the tool assembly 13 further includes a tool 132 for cutting the sealing gasket 2. A tool receiving groove 1312 is arranged on the sliding member 131 and penetrates from the side away from the chute 1311 to the side close to the chute 1311. The tool 132 is received in the tool receiving groove 1312, and the cutting head 1321 of the tool 132 is exposed outside the sliding member 131. Specifically, in a specific embodiment of the present invention, the size of the tool receiving groove 1312 is similar to the size of the tool 132, so as to ensure that the tool 132 will not shake too much in the tool receiving groove 1312 and avoid the tool 132 affecting the cutting effect due to shaking during cutting. The cutting head 1321 is exposed outside the sliding member 131, that is, the cutting head 1321 is the part for cutting the sealing gasket 2. It can be understood that by sliding the sliding member 131, the sliding member 131 slides on the slide rail 112. When the sliding member 131 passes through the accommodating groove 111 located on the slide rail 112, the cutting head 1321 enters the accommodating groove 111 and passes through the pressing member 12, and then the cutting head 1321 cuts a part of the sealing gasket 2 in the opening window 121 to form the cut 21.

[0038] At the same time, please also combine Figure 8, to ensure the stability of the tool 132 during cutting, the tool assembly 13 further includes a tool fixing member 133. A fixing member receiving groove 1313 is provided on an adjacent surface of the sliding member 131 away from the chute 1311. The fixing member receiving groove 1313 communicates with the tool receiving groove 1312, and the tool fixing member 133 is received in the fixing member receiving groove 1313. In a specific embodiment of the present invention, the tool fixing member 133 is a bolt, and the tool fixing member 133 is threadedly connected to the fixing member receiving groove 1313. Since the fixing member receiving groove 1313 communicates with the tool receiving groove 1312, when the tool fixing member 133 is received in the fixing member receiving groove 1313, it can enter the tool receiving groove 1312 and abut against the tool 132, thereby fixing the tool 132. Specifically, rotate the tool fixing member 133 so that the tool fixing member 133 is threadedly connected to the fixing member receiving groove 1313, thereby ensuring that the tool fixing member 133 can be fixed on the sliding member 131. When rotating the tool fixing member 133, the tool fixing member 133 moves in the direction of the tool 132 and finally abuts against the tool 132, thereby fixing the tool 132 in the tool receiving groove 1312 and preventing the tool 132 from jittering or shaking.

[0039] In other specific embodiments of the present invention, the number of the tool fixing members 133 can be set according to actual needs, and the number of the fixing member receiving grooves 1313 is set corresponding to the number of the tool fixing members 133. For example, if the number of the tool fixing members 133 is two, the number of the fixing member receiving grooves 1313 is correspondingly two, and the two tool fixing members 133 are respectively received in the two fixing member receiving grooves 1313. The tool fixing member 133 can also be a magnetic structure. Correspondingly, the material of the tool 132 needs to be a material that can be attracted by a magnet. When the tool is placed in the tool receiving groove 1312, the tool will be attracted by the magnetic tool fixing member 133 and thus adsorbed on the tool fixing member 133, thereby fixing the tool 132.

[0040] Please refer to Figure 1 and Figure 9, to ensure that the cutter head 1321 can smoothly pass through the pressing member 12 and cut the sealing gasket 2, a first cutting groove 1121 is provided on the slide rail 112, and a second cutting groove 123 is provided on the surface of the pressing member 12 away from the accommodating groove 111. The first cutting groove 1121 passes through the accommodating groove 111 and communicates with the second cutting groove 123. The cutter head 1321 of the cutting tool 132 can slide in the first cutting groove 1121 and the second cutting groove 123. The distance S1 from the first cutting groove 1121 to the surface of the cutting table 11 away from the accommodating groove 111 is less than the distance S2 from the surface of the sealing gasket 2 close to the pressing member 12 to the surface of the cutting table 11 away from the accommodating groove 111. The distance S3 from the second cutting groove 123 to the surface of the cutting table 11 away from the accommodating groove 111 is less than the distance S2 from the surface of the sealing gasket 2 close to the pressing member 12 to the surface of the cutting table 11 away from the accommodating groove 111.

[0041] It can be understood that the first cutting groove 1121 is used for the cutter head 1321 to move in the cutting table 11, and the first cutting groove 1121 communicates with the accommodating groove 111. Therefore, the cutter head 1321 can enter the accommodating groove 111 through the first cutting groove 1121. After the cutter head 1321 enters the accommodating groove 111, the cutter head 1321 can enter the second cutting groove 123 communicating with the first cutting groove 1121, and the cutter head 1321 passes through the pressing member 12 through the second cutting groove 123. After the cutter head 1321 passes through the second cutting groove 123, it can pass through the opening window 121, thereby cutting a part of the sealing gasket 2 in the opening window 121. Further, to ensure that the cutter head 1321 can smoothly enter the second cutting groove 123 from the first cutting groove 1121, the distance S1 is greater than or equal to the distance S3. At the same time, to ensure that the cutter head 1321 can smoothly cut a part of the sealing gasket 2 located in the opening window 121 after passing through the second cutting groove 123, the distance S3 should be less than the distance S2.

[0042] Please refer to Figure 9 - Figure 11, for the convenience of taking out the sealing gasket 2 from the accommodating groove 111, the cutting device 1 further includes an ejecting member 14. The ejecting member includes a body 141 and a rotating shaft 142. The body 141 includes a key portion 1411, a connecting portion 1412, and an ejecting portion 1413. One end of the connecting portion 1412 is connected to the ejecting portion 1413, and the other end is connected to the key portion 1411. The key portion 1411 is for the user to press, and the ejecting portion 1413 is for ejecting the sealing gasket 2 from the accommodating groove 111. The rotating shaft 142 is arranged on the connecting portion 1412. When the key portion 1411 is pressed, the body 141 can rotate around the rotating shaft 142. Specifically, in a specific embodiment of the present invention, an ejecting member receiving groove 113 is provided on a side of the cutting table 11 away from the accommodating groove 111. The ejecting member 14 is received in the ejecting member receiving groove 113, and the ejecting portion 1413 is arranged close to the accommodating groove 111. The cutting table 11 is provided with a first through groove 114 that penetrates the accommodating groove 111 and the ejecting member receiving groove 113. A second through groove 115 that penetrates from a side of the cutting table 11 away from the ejecting member 14 to the ejecting member receiving groove 113 is provided at a position of the cutting table 11 corresponding to the key portion 1411. A ejector pin 1414 protruding relative to the ejecting portion 1413 is arranged on the ejecting portion 1413. The ejector pin 1414 is received in the first through groove 114. The key portion 1411 extends into the second through groove 115 and is exposed outside the cutting table 11. During use, the key portion 1411 exposed outside the cutting table 11 is pressed, so that the key portion 1411 rotates around the rotating shaft 142 in the second through groove 115 in a direction away from the accommodating groove 111. The movement of the key portion 1411 will drive the movement of the ejector pin 1414. At this time, the ejector pin 1414 rotates around the rotating shaft 142 in the first through groove 114 in a direction close to the accommodating groove 111 until the ejector pin 1414 enters the accommodating groove 111 and abuts against the sealing gasket 2 located in the accommodating groove 111. At this time, when the key portion 1411 is continuously pressed, the ejector pin 1414 continues to rotate in a direction close to the accommodating groove 111. The ejector pin 1414 will drive the movement of the sealing gasket 2, and then eject the sealing gasket 2 from the accommodating groove 111. Through the ejecting member 14, the user can very conveniently and easily take out the sealing gasket 2 and the pressing member 12 pressing on the sealing gasket 2 from the accommodating groove 111. It can be understood that the number of the ejector pins 1414 and the first through grooves 114 is set corresponding to the number of the accommodating grooves 111. The position of the ejector pin 1414 on the ejecting portion 1413 is set corresponding to the position of the first through groove 114.

[0043] Further, please continue to refer toFigure 1 , to achieve the automatic cutting of the sealing gasket 2 by the cutting device 1, the cutting device 1 further includes a drive system 15. The drive system 15 includes a power source 151 and a drive connecting member 152. The drive system 15 is connected to the tool assembly 13 through the drive connecting member 152. The power source 151 can drive the drive connecting member 152 to move. The movement of the drive connecting member 152 drives the tool assembly 13 to move, so that the tool assembly 13 does not need to be manually moved. Specifically, in a specific embodiment of the present invention, the drive system 15 further includes a reciprocating screw rod 153. The reciprocating screw rod 153 is arranged parallel to the slide rail 112, so as to ensure that the movement trajectory of the drive connecting member 152 is parallel to the movement trajectory of the sliding member 131. The drive connecting member 152 is sleeved on the reciprocating screw rod 153, and the drive connecting member 152 is threadedly connected to the reciprocating screw rod 153. One end of the power source 151 is connected to the reciprocating screw rod 153. The power source 151 can be a motor. The motor drives the reciprocating screw rod 153 to rotate. After the reciprocating screw rod 153 rotates, it can drive the drive connecting member 152 to move in a direction away from the power source 151. The movement of the drive connecting member 152 drives the sliding member 131 to move. The movement of the sliding member 131 further causes the tool 132 in the sliding member 131 to move. When the sliding member 131 passes through the receiving groove 111, the tool 132 will complete the cutting of the sealing gasket 2. When the drive connecting member 152 moves to one end of the reciprocating screw rod 153 away from the power source 151, due to the characteristics of the reciprocating screw rod 153, the drive connecting member 152 will "return the same way" at this time. The drive connecting member 152 will move in a direction close to the power source 151. By analogy, the drive connecting member 152 will make a reciprocating motion on the reciprocating screw rod 153, thereby driving the sliding member 131 to reciprocate on the slide rail 112. That is, the tool 132 will cut the sealing gasket 2 back and forth, so as to ensure that the cut of the cut 21 formed by the tool 132 is neat, avoid affecting the overall sealing performance of the sealing gasket 2 due to the uneven cut of the cut 21, and at the same time improve the yield rate of the sealing gasket 2 after the cut 21 is cut out.

[0044] Further, the cutting device 1 may further include a main body (not shown in the figure) and an infrared sensor (not shown in the figure). The infrared sensor is disposed near the power source 151. After the power source 151 drives the slider 131 to move back and forth on the slide rail 112, the slider 131 passes by the infrared sensor. After the infrared sensor recognizes that the slider 131 has passed by, the infrared sensor transmits an instruction to the main body. After the main body recognizes the instruction, it will cut off the power supply of the power source 151, thereby causing the power source 151 to no longer drive the reciprocating lead screw 153 to rotate, and further causing the driving connecting member 152 and the slider 131 to stop moving. Through the above arrangement, after the slider 131 moves back and forth, that is, after the cutter 132 cuts the sealing gasket 2 back and forth, it will automatically stop. At this time, the sealing gasket 2 can be taken out of the receiving groove 111, and the uncut sealing gasket 2 can be placed into the receiving groove 111, and then the power source 151 can be started to cut the slit 21 of the next batch of the sealing gaskets 2. Thereby improving the convenience of the cutting device 1 and improving the production efficiency.

[0045] In other specific embodiments of the present invention, the reciprocating lead screw 153 may also be replaced by a telescopic rod. The power source 151 can drive the telescopic rod to extend and contract, and the process of the telescopic rod extending and contracting will drive the slider 131 to move. The power source 151 may also be a pneumatic device. At this time, the reciprocating lead screw 153 will be replaced by a rod-shaped object with a smooth outer surface. The pneumatic device will blow the slider 131 to move away from the power source 151. At this time, an infrared sensor can be disposed near one end of the rod-shaped object away from the power source 151. After the slider 131 passes by the infrared sensor, the power source 151 loses power, and the slider 131 will automatically stop. At this time, the slider 131 can be manually reset.

[0046] Compared with the prior art, a gasket cutting system of the present invention has the following advantages: The cut formed by the cutting device of the present invention has an arc-shaped structure. The arc-shaped cut has better sealing performance compared to a straight cut or cuts of other shapes. When an instrument passes through the cut, the position with a deeper cut depth will be more strongly squeezed by the instrument, and the position with a deeper cut depth will fit the instrument more tightly, thereby further ensuring the sealing performance of the sealing gasket. At the same time, in a specific embodiment of the present invention, when cutting the cut, only by sliding the tool assembly on the cutting table can the operation of completely cutting the cut be completed. The operation is very simple, time-saving and labor-saving, reducing the time cost and labor cost. At the same time, the cuts formed after cutting the sealing gasket with the cutting device can be highly unified in terms of size and shape. The size and shape of each cut can be precisely controlled, thereby ensuring the sealing performance of each sealing gasket and improving the yield rate of the sealing gasket.

[0047] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the principle of the present invention shall be included within the protection scope of the present invention.
