Description

Technical Field

[0001] This invention relates to a tissue reinforcement installer that enables accurate and easy installation of adhesive tissue reinforcement material into an automatic suture device in a short time, reduces the occurrence of poor installation, and a tissue reinforcement installer kit using the tissue reinforcement installer. Background Technology

[0002] Previously, stapler-type automated staplers with many embedded staples were used for tissue suturing. However, when applied to lungs, air leakage from the suture site was a problem. In addition, when applied to soft tissues, tissue damage and breakage sometimes occurred.

[0003] Therefore, to prevent air or bodily fluid leakage and tissue damage, bio-absorbable reinforcing materials (e.g., Patent Documents 1 and 2) are used in conjunction with automatic suture devices. The reinforcing materials in Patent Documents 1 and 2 form a tubular structure by sewing together two opposite edges of a piece of bio-absorbable nonwoven fabric, or by overlapping two pieces of bio-absorbable nonwoven fabric or one piece of bio-absorbable nonwoven fabric and one piece of stretch knitted fabric and sewing together the opposite edges. Then, the automatic suture device is installed by inserting the end of its staple cartridge into the tubular structure and sutured together with the tissue, thereby reinforcing the tissue. Furthermore, after reinforcement, unwanted areas can be separated by pulling the threads extending from the reinforcing material, thus improving operability. Moreover, since the reinforcing material is made of bio-absorbable nonwoven fabric, it can ultimately be absorbed into the body after reinforcement is no longer needed.

[0007] Patent Document 2: Japanese Patent No. 4675237 Summary of the Invention

[0008] The problem that the invention aims to solve

[0009] To prevent misalignment during the operation of automatic suture machines, existing reinforcing materials for these machines are formed by combining a reinforcing tissue blank and a stretchable blank into a cylindrical shape, thus ensuring a tight seal with the automatic suture machine. However, due to the wide variety of sizes available for the staple cartridges in automatic suture machines, there are instances where the size of the cartridge prevents the reinforcing material from achieving a sufficient seal, leading to misalignment. Furthermore, even when using reinforcing materials suitable for the staple cartridge size, gaps can sometimes occur near the needle feet of the blank, causing further misalignment.

[0010] On the other hand, in endoscopic surgery using automated suture devices, multiple tubular ports are inserted into the patient's body to insert instruments such as endoscopes and automated suture devices. In this case, existing reinforcing materials are installed around the staple cartridge of the automated suture device, which can sometimes cause jamming when the automated suture device inserts the port. Furthermore, because the reinforcing material is positioned around the staple cartridge, the size of the automated suture device with the reinforcing material increases. Therefore, if a port with a diameter larger than the automated suture device itself is not used, the automated suture device cannot pass through. From the perspective of reducing patient burden, there is a need for reinforcing materials that can pass through smaller diameter ports.

[0011] Therefore, the applicant of this application proposes a suture reinforcement material for an automatic suture device, which is constructed by integrally laminating a fabric layer made of bioabsorbable material and a sponge layer made of water-soluble polymer. This suture reinforcement material for an automatic suture device generates adhesive force through the absorption of moisture by the sponge layer, allowing it to be installed in the automatic suture device by pasting it onto the staple cartridge. Therefore, it can be used in automatic suture devices of all sizes, and it offers high tube insertion throughput, minimizing displacement during operation of the automatic suture device.

[0012] However, this type of adhesive tissue reinforcement material adheres to the automatic suture device after being soaked in water, making installation more complex than with conventional cylindrical tissue reinforcement materials. Furthermore, if the installation position deviates, it needs to be torn off and re-attached. Therefore, a method is needed to easily and accurately install adhesive tissue reinforcement materials into the automatic suture device.

[0013] In view of the above problems, the object of the present invention is to provide a tissue reinforcement installer that can correctly and easily install an adhesive tissue reinforcement material into an automatic suture device in a short time, and a tissue reinforcement material installation kit using the tissue reinforcement material installer.

[0028] This disclosure 12 is: the fixing groove of the tissue reinforcement material installer according to any one of disclosures 1 to 11 holds the tissue reinforcement material installation kit of the adhesive tissue reinforcement material.

[0029] This disclosure 13 is a tissue reinforcement material mounting kit as described in this disclosure 12, with a cover mounted on the end of the automatic suture device on the operating hand side of the tissue reinforcement material mounter.

[0030] The following describes in detail the tissue reinforcement material installer of the present invention and the adhesive tissue reinforcement material used thereon. First, the tissue reinforcement material installer of the present invention will be described in detail.

[0031] The tissue reinforcement material installer of the present invention is a tissue reinforcement material installer for fixing an adhesive tissue reinforcement material to an automatic suture device.

[0032] Compared to existing cylindrical tissue reinforcement materials, adhesive tissue reinforcement materials are virtually non-jammable and can be used regardless of their size. However, to install adhesive tissue reinforcement materials into an automatic suture device, they must be adhered to a designated position on the device, which presents a challenge in quickly and accurately installing them. By using the tissue reinforcement material installer of this invention, adhesive tissue reinforcement materials can be installed into the automatic suture device quickly, accurately, and easily, regardless of the installer's skill level.

[0033] The tissue reinforcement material installer of the present invention has a plate-shaped component with recesses at opposite positions on both sides of the plate-shaped component.

[0034] By providing recesses at opposite positions on both sides of a plate-like component (the surfaces of the component perpendicular to the thickness direction), and holding the adhesive tissue reinforcement material in these recesses, the operability of transporting and storing the adhesive tissue reinforcement material can be improved. Furthermore, by immersing the adhesive tissue reinforcement material along with the tissue reinforcement material installer in water or an aqueous solution (hereinafter simply referred to as an aqueous solution), two pieces of adhesive tissue reinforcement material can be simultaneously installed in an automatic suture device by clamping the recesses. Examples of such aqueous solutions include sterile water, physiological saline, and buffer solutions. Additionally, "plate-like" here refers to a flat shape with a thickness sufficient to be clamped by an automatic suture device.

[0035] Each of the aforementioned recesses has a shape corresponding to the shape of the portion of the automatic suture device where the adhesive tissue reinforcement material is installed, and each of the aforementioned recesses is continuous up to the same end of the aforementioned component.

[0036] By shaping the aforementioned recesses to correspond to the shape of the area where the adhesive tissue reinforcement material is installed in the automatic suture device, the adhesive tissue reinforcement material can be correctly installed in a specified position. Furthermore, since the two recesses are continuous up to the same end of the component, the automatic suture device can be inserted from one side of the continuous recesses. "Continuous up to the same end" means that the open ends of the two recesses are continuous up to the same side of the component; "side" refers to the surface perpendicular to both sides of the plate-shaped component.

[0037] Each of the above-mentioned recesses has a brush-like protrusion on its bottom surface.

[0038] When the adhesive tissue reinforcement material is placed in the recessed area of ​​a flat surface and clamped in by an automatic stapler, the part near the hand end of the automatic stapler first contacts the bottom surface of the recess and is obstructed. Therefore, there is a possibility that the adhesive tissue reinforcement material cannot make sufficient contact with the part near the front end of the automatic stapler and cannot be clamped in. As a result, sometimes poor installation such as lifting or peeling of the adhesive tissue reinforcement material occurs near the front end of the automatic stapler.

[0039] In this invention, by providing brush-like protrusions (hereinafter simply referred to as protrusions) on the bottom surface of the recess, when the automatic suture contacts the protrusions at the bottom of the recess, the protrusions tilt sequentially as the clamping progresses, creating an inclination at the bottom. Furthermore, when the bottom tilts, the thickness of the bottom on the operator's side of the automatic suture becomes thinner than the front side, thus preventing the clamping from stopping midway. Compared to a recess with a flat bottom surface, the automatic suture can be fully clamped to the front end. As a result, poor installation, such as warping or peeling of the adhesive tissue reinforcement material near the front end of the automatic suture, can be suppressed. The front end of the protrusion can be flat or pointed, but a flat front end is preferred because it allows for pressing the adhesive tissue reinforcement material against the automatic suture with a larger area, facilitating sufficient adhesion of the adhesive tissue reinforcement material. Additionally, in this specification, the bottom of the recess refers to the area where the bottom surface of the recess and the protrusion meet.

[0040] There is no particular limitation on the length of the protrusion, but from the viewpoint of further increasing the force of pressing the adhesive tissue reinforcement material against the automatic suture device and making it difficult for the adhesive tissue reinforcement material to shift or fall off, it is preferably 0.5 mm or more, more preferably 1 mm or more, even more preferably 2 mm or more, preferably 5 mm or less, more preferably 3 mm or less, and even more preferably 2.8 mm or less.

[0041] Preferably, the length of the brush-shaped protrusion is shortened at the end of the automatic stitcher facing the recessed part.

[0042] The length of the protrusion decreases towards the operator's hand side of the automatic suture device, creating an inclination at the bottom of the recess even when the protrusion is not tilted. This allows for more reliable clamping of the automatic suture device to the front end, reducing the risk of improper installation. Furthermore, the elastic force of the protrusion allows the adhesive tissue reinforcement material to adhere more strongly to the front end of the automatic suture device, thus suppressing warping and peeling of the adhesive tissue reinforcement material at the front end. The length of the protrusion can decrease continuously towards the operator's hand side of the automatic suture device or decrease in a stepped manner. When the length of the protrusion decreases in a stepped manner, it is preferable that the length decreases in a manner where the step differences are equal.

[0043] In addition, in this specification, the operating hand side of the automatic suture refers to the direction near the hand end of the automatic suture when the tissue reinforcement material installer of the present invention is inserted into the automatic suture; in other words, it refers to the direction of the open end side of the recess (hereinafter also referred to as the operating hand side). Furthermore, the front end side of the automatic suture refers to the direction opposite to the operating hand side of the automatic suture (hereinafter also referred to as the front end side only).

[0044] When the length of the protrusion shortens toward the operating hand side of the automatic stitcher, from the viewpoint of clamping the automatic stitcher more firmly, the difference between the maximum and minimum length of the protrusion is preferably 0.1 mm or more, more preferably 0.5 mm or more, more preferably 1.5 mm or less, and more preferably 1.0 mm or less.

[0045] The thickness (cross-sectional area in the planar direction) of the aforementioned protrusion is not particularly limited, as long as it allows for tilting as the automatic suture clamps in, and on the other hand, its hardness is sufficient to press the tissue reinforcement material against the automatic suture with sufficient force up to the tilt. However, from the viewpoint of further increasing the force pressing the tissue reinforcement material against the automatic suture to make it more difficult for the tissue reinforcement material to shift or fall off, 0.5 mm is preferred. 2 The above, preferably 1.0mm 2 The preferred size is 2.0mm. 2 The following is more preferably 1.5mm 2 The following is a further explanation. Additionally, when the thickness of the protrusion is not fixed, the thickness of the protrusion mentioned above refers to the value at its maximum thickness. Furthermore, in this specification, the planar direction refers to the plane direction perpendicular to the thickness direction of the tissue reinforcement material installer.

[0046] The density of the aforementioned protrusions is not particularly limited, as long as the amount of protrusions reliably tilts when the automatic suture device is inserted is acceptable, but a surface density of 9 protrusions / cm² is preferred. 2 More than 25 per cm 2Below. By setting the amount of the aforementioned protrusions to the areal density within the aforementioned range, it is possible to reliably tilt the material when it is inserted into the automatic suture device, and before tilting, to ensure that the adhesive tissue reinforcement material is evenly distributed and contacts and presses against the automatic suture device over a larger area. More preferably, the areal density of the aforementioned protrusions is 16 protrusions / cm². 2 above.

[0047] Each of the aforementioned recesses has a retaining groove on its side for holding the aforementioned adhesive tissue reinforcement material in place.

[0048] By providing grooves at opposite positions on the sides of each of the aforementioned recesses and inserting the adhesive tissue reinforcement material into these grooves, it is possible to prevent the adhesive tissue reinforcement material from falling off. Furthermore, the adhesive tissue reinforcement material held in the aforementioned fixing grooves is released from the fixing grooves by the force exerted when the automatic suture device is inserted. From the viewpoint of preventing the adhesive tissue reinforcement material from falling off and reliably releasing it when the automatic suture device is inserted, the distance between the ends of the two grooves of the aforementioned fixing groove is preferably 0.5 mm or more and 2 mm or less wider than the width of the adhesive tissue reinforcement material, more preferably 0.5 mm or more and 1.5 mm or less.

[0049] Preferably, each of the above-mentioned recesses is wider when facing the operating hand side of the automatic stitcher.

[0050] The recessed structure, being a V-shaped structure that widens towards the operator's hand side of the automatic stitcher, facilitates easy guidance of the automatic stitcher into the recess. Furthermore, as will be explained later, when the bottom of the recess is connected to other parts via a bottom retaining groove, the bottom of the recess can be more easily pulled out during the release of the automatic stitcher.

[0051] From the viewpoints of making it easier to guide the automatic stitcher towards the recess and from the viewpoints of operability, the degree of widening of the recess, that is, the difference in width between the end of the recess on the operating hand side and the end on the front end side, is preferably 0.1 mm or more, more preferably 0.4 mm or more, more preferably 0.6 mm or less, and more preferably 0.3 mm or less.

[0052] Preferably, the portion at the bottom of the aforementioned recess that connects with the front end of the aforementioned automatic stitcher becomes the opening.

[0053] Automatic suture devices come in various front-end shapes, including those with a hook-shaped front end. When inserting an automatic suture device with such a hook-shaped front end, the front end sometimes contacts the bottom of the recess before insertion is complete, resulting in insufficient installation of the adhesive tissue reinforcement material. When the portion at the bottom of the recess that connects to the front end of the automatic suture device forms an opening, the front end no longer interferes with the bottom of the recess, allowing for reliable installation of the adhesive tissue reinforcement material even with an automatic suture device having a hook-shaped front end. The size and shape of this opening are not particularly limited, as long as the automatic suture device with the hook-shaped front end can be fully inserted.

[0054] Preferably, the bottom of the aforementioned recess protrudes from the side at the end on the operator's hand side.

[0055] The bottom of the recess protrudes from the side of the recess at the end on the operator's hand side, creating a structure where the protruding bottom is discontinuous with other parts, allowing for stronger clamping of the automatic stitcher. The protruding length of the bottom of the recess is preferably 1.0 mm or more, more preferably 2.0 mm or more, more preferably 10.0 mm or less, and more preferably 5.0 mm or less.

[0056] The thickness between the bottoms of each of the above-mentioned recesses is preferably 3 mm or more and 8 mm or less.

[0057] By ensuring the thickness between the bottoms of the recesses is within the aforementioned range, the automatic stitcher can be more reliably inserted into the recesses. More preferably, the thickness between the bottoms of each recess is 4 mm or more, and more preferably 6 mm or less. Furthermore, the thickness between the bottoms of each recess refers to the thickness including the aforementioned protrusions, that is, the thickness from the tip of the protrusion of one recess to the tip of the protrusion of the other recess.

[0058] The tissue-strengthening material installer of the present invention preferably has a different material at the bottom of the recess and other parts.

[0059] By separating the material of the bottom of the aforementioned recess from that of the other parts, the aforementioned protrusion can be made to have a firmness that makes it easy to tilt when clamped into an automatic suture device and improve the overall strength of the tissue reinforcement material installer.

[0060] When the material at the bottom of the aforementioned recess differs from the material of the other portions, it is preferable that the bottom of the recess is installed and held in the other portions via a bottom retaining groove provided in the other portions. By employing such a structure, the adhesive tissue reinforcement material can be installed and the automatic suture device can be released by pulling out the bottom of the recess after the automatic suture device is inserted, thus enabling the installation of the adhesive tissue reinforcement material in a shorter time.

[0061] When the other parts are installed at the bottom of the recess via the bottom retaining groove, it is preferable that the bottom retaining groove widens towards the operator's hand. When the bottom retaining groove widens towards the operator's hand, the bottom of the recess is easier to pull out, thus allowing for the installation of the adhesive tissue reinforcement material in a shorter time.

[0062] From the viewpoint of balancing the retention performance and ease of extraction of the bottom of the recess, the bottom retaining groove is preferably located at the end of the front end and the end of the operator's hand side, and the difference in width between the bottom retaining grooves is 0.1 mm or more, more preferably 0.3 mm or more, more preferably 0.5 mm or less, and more preferably 0.4 mm or less.

[0063] When the material at the bottom of the aforementioned recess is the same as the material of the other parts, the thickness of the outer edge of the aforementioned tissue reinforcement material installer is preferably 5.0 mm or more and 10.0 mm or less.

[0064] With the thickness of the outer edge within the aforementioned range, bending deformation is less likely to occur during the operation of the tissue reinforcement material installer, allowing for more reliable retention of the adherent tissue reinforcement material. Furthermore, the material forming the outer edge is not limited when the bottom of the recess and other parts are made of different materials; therefore, the thickness can be appropriately selected based on the material. Here, "outer edge" refers to the portion of the recess constituting the tissue reinforcement material installer (component) excluding the bottom.

[0065] The tissue reinforcement material installer of the present invention is preferably located at the end of the component that is continuous with the recess, and portions on both sides of the recess protrude from the end of the recess.

[0066] At the end of the recess that is continuous with the outside (the end on the operating hand side), the portions on both sides of the recess (outer edges) protrude from the end of the recess. That is, at the operating hand side end of the tissue reinforcement material installer, the ends of the outer edges protrude more than the ends of the recess, and the operating hand side end of the tissue reinforcement material installer becomes concave. Thus, the portions on both sides of the protruding recess (outer edges) serve as guides for the automatic suture device, thereby enabling more reliable installation of the adhesive tissue reinforcement material at the designated position of the automatic suture device. There is no particular limitation on the protruding length of the portions on both sides of the recess (the protruding length of the outer edges), but from the viewpoint of guiding performance and operability of the automatic suture device, it is preferably 10 mm or more and 50 mm or less.

[0067] The tissue reinforcement material installer of the present invention preferably has guide walls along the recess on both sides of the long side of the recess.

[0068] By providing guide walls along the recess on both sides of the recess, it is easier to guide the automatic stitcher into the recess and to easily clamp the automatic stitcher in.

[0069] Preferably, the guide wall has an inner surface that slopes downward toward the bottom of the recess. (Hereinafter, the downward-sloping portion of the inner surface of the guide wall is referred to as the inner surface slope portion.) By making the inner surface of the guide wall slope downward toward the bottom of the recess, the automatic suture is guided along the slope toward the bottom of the recess, thus making it easier to insert the automatic suture. The slope angle of the inner surface slope portion is preferably 20° or more, and preferably 40° or less. Here, when observing the cross-section in the height direction (thickness direction of the tissue reinforcement material installer) of the guide wall, the slope angle of the inner surface slope portion refers to the smaller angle between the vertical line drawn from the upper end of the side abutting the inner surface of the guide wall to the lower side and the angle formed by the line drawn from the upper end of the side abutting the inner surface of the guide wall to the lower side. In addition, in this specification, "lower" refers to the direction of the bottom surface side of the recess in the thickness direction of the tissue reinforcement material installer, and "upper" refers to the opposite direction. Furthermore, "inner" refers to the direction of the recess side, and "outer" refers to the opposite direction.

[0070] From the viewpoint of operability and ease of insertion of the automatic stitcher, the height of the guide wall is preferably 1 mm or more, more preferably 2 mm or more, preferably 7 mm or less, and more preferably 4 mm or less. Furthermore, from the viewpoint of further improving the ease of insertion of the automatic stitcher and preventing it from getting stuck, the length of the guide wall, starting from the front end (front end) of the recess, is preferably 20% or more of the length of the recess, more preferably 40% or more, more preferably 80% or less, and more preferably 60% or less.

[0071] Preferably, the end of the guide wall on the operator's hand side of the automatic stitcher is inclined downwards toward the operator's hand side. (Hereinafter, the downwardly inclined portion of the end of the guide wall on the operator's hand side will be referred to as the operator's hand side inclined portion.)

[0072] By tilting the hand-side end of the guide wall downwards, the automatic suture device is less likely to get stuck when the tissue reinforcement material installer is inserted from the hand-side, thus improving the guiding ability of the automatic suture device towards the tissue reinforcement material installer. From the viewpoint of further improving the guiding ability of the automatic suture device, the tilt angle of the aforementioned hand-side tilt portion is preferably 30° or more, and preferably 50° or less. Furthermore, from the same viewpoint, the proportion of the aforementioned hand-side tilt portion to the entire guide wall is preferably 2% or more, more preferably 5% or more, more preferably 30% or less, and more preferably 20% or less. Here, the tilt angle of the hand-side tilt portion refers to the smaller angle between the vertical line drawn downwards from the front end of the upper side of the hand-side tilt portion on the outer surface of the guide wall and the upper side of the hand-side tilt portion.

[0073] The tissue reinforcement material installer of the present invention preferably has a handle at the end of the front end side of the aforementioned automatic suture device.

[0074] By incorporating a handle into the tissue reinforcement material installer, operation becomes easy, and hands do not get wet when the installer is immersed in an aqueous solution.

[0075] The handle portion can be shaped for easy gripping with fingers, but a recessed structure along the long side of the recess is preferred. This handle portion structure makes it easier to grip the tissue-reinforcing material installer with fingers and reduces slippage. Furthermore, it is more preferable that the handle portion has anti-slip ribs along the long side of the recess. By providing anti-slip ribs to the handle portion, it is even more difficult for fingers to slip.

[0076] Preferably, the handle portion has a notch or groove on the side of the recessed portion.

[0077] By providing a notch or groove on the side of the recessed part of the handle, the front end of the automatic stitcher is less likely to interfere with the handle, making it easier to clamp the automatic stitcher. As long as it does not interfere with the front end of the automatic stitcher, the shape and size of the notch or groove are not particularly limited; for example, a semi-circular or rectangular shape is provided.

[0078] The material of the aforementioned component, namely the material of the tissue reinforcement material installer of the present invention, is not particularly limited, but it is preferable to have a hardness that prevents the protrusion from tilting when clamped into the automatic suture device. Examples of such materials include silicone rubber, polyurethane rubber, and polyolefin elastomers. Among these, heat resistance and dimensional stability are required when the adhesive reinforcement material is held in place during manufacturing for sterilization and packaging; therefore, highly durable silicone rubber is preferred. Furthermore, when the bottom of the recess and the other portions are made of different materials, the material of the bottom of the recess is preferably one of the aforementioned materials, while the materials of the other portions are preferably polyethylene or polypropylene from the viewpoint of strength and ease of molding.

[0079] The manufacturing method of the tissue-reinforcing material installer of the present invention is not particularly limited. When the bottom of the recess and other parts are made of the same material, injection molding, stamping, cutting, etc., can be cited as examples. When the bottom of the recess and other parts are made of different materials, for example, a method can be cited where a U-shaped housing part and a platform part are manufactured separately, and the platform part is installed in the bottom retaining groove. The U-shaped housing part has the aforementioned fixing groove and the aforementioned bottom retaining groove, and the platform part includes a bottom of the recess with brush-like protrusions and mounting portions on both sides corresponding to the aforementioned bottom retaining groove. The housing and platform part can be manufactured by injection molding, stamping, cutting, etc.

[0080] The tissue reinforcement material installer of the present invention can hold the adhesive tissue reinforcement material at the surgical site. However, by sterilizing, packaging, transporting and storing the adhesive tissue reinforcement material while holding it, the operability of the adhesive tissue reinforcement material can be improved and the operation at the surgical site can be further simplified.

[0081] Such a tissue reinforcement material mounting kit, in which the adhesive tissue reinforcement material is held in the fixing groove of the tissue reinforcement material mounter of the present invention, is also one aspect of the present invention.

[0082] The tissue reinforcement material installation kit of the present invention preferably has a cover installed on the end of the automatic suture device on the operating hand side of the tissue reinforcement material installer.

[0083] By protecting the operating hand end of the automated suture device for the tissue reinforcement material installation kit with a cap, the adhesive tissue reinforcement material is less likely to fall off during transportation and storage. The shape of the cap can be appropriately determined to match the shape of the operating hand end of the automated suture device for the tissue reinforcement material installer. Furthermore, the cap can be removed at the surgical site before immersing the tissue reinforcement material installation kit in an aqueous solution.

[0084] Here, the form and method of use of the tissue reinforcement material installer of the present invention will be described in detail with reference to the accompanying drawings. Figure 1 This is a schematic diagram illustrating an example of the tissue-reinforcing material installer of the present invention. Figure 1 and the following discussion Figure 2 , 3 In the image, the right rear side is the front end, and the left front side is the operator's hand side. Figure 1 The example illustrates a structure-reinforced material mount where the bottom of the recess (platform section) and other parts (shell section) are made of different materials. For example... Figure 1As shown, the tissue reinforcement material installer 1 of the present invention has recesses 2 formed at opposite positions on both sides of the plate-shaped component, and the two recesses 2 have brush-like protrusions 3 on their bottom surfaces. Fixing grooves 4 for holding the adhesive tissue reinforcement material 5 are provided on the sides of the recesses 2, and the adhesive tissue reinforcement material 5 is held by inserting it into the fixing grooves 4. Furthermore, the two recesses 2 are continuous up to the same end (same side) of the component (tissue reinforcement material installer 1), so when the automatic suture is clamped from the continuous end (open end) of the recesses 2 of the tissue reinforcement material installer 1 in a manner that fully engages with the recesses 2, two pieces of adhesive tissue reinforcement material can be simultaneously and correctly installed in the prescribed positions of the automatic suture. Furthermore, by employing a structure in which the end of the outer edge portion (the portion of the recess 2 other than its constituent bottom) protrudes more than the end of the recess 2 on the operator's side, the protrusion becomes a guide portion toward the recess 2, making it easier to clamp the automatic suture. Furthermore, when an opening 6 is provided at the bottom of the recess 2 where it connects to the front end of the automatic suture device, even when using an automatic suture device with a hook-shaped front end, the front end is retracted into the opening 6 during insertion, thus allowing the automatic suture device to be completely inserted into the tissue reinforcement material installer. Additionally, [the following is provided] Figure 1 The groove between the two sets of fixing grooves 4 is a groove (bottom retaining groove 7) for installing the bottom (platform part) of the recess.

[0085] Figure 2 This is a schematic diagram illustrating one usage state of the tissue-strengthening material installer of the present invention. (See diagram for example.) Figure 2 As shown, in the method of using the tissue reinforcement material installer 1 of the present invention, firstly, the adhesive tissue reinforcement material 5 is held between the fixing grooves 4 of the two recesses. Furthermore, the operation of holding the adhesive tissue reinforcement material 5 can be performed at the surgical site, or the adhesive tissue reinforcement material 5 can be held during manufacturing for sterilization, packaging, transportation, and storage. Next, the adhesive tissue reinforcement material 5, together with the tissue reinforcement material installer 1, is immersed in an aqueous solution such as sterile water, physiological saline, or buffer solution. Then, it is removed from the aqueous solution such as sterile water, physiological saline, or buffer solution, and the automatic suture device 8 is inserted from the continuous end (open end) side of the recesses. By clamping into the recesses, two adhesive tissue reinforcement materials 5 are simultaneously installed in the automatic suture device 8. At this time, on the operating hand side of the automatic suture device 8, which first contacts the adhesive tissue reinforcement material 5, the protrusion tilts as it is clamped in, thus ensuring that the automatic suture device 8 is clamped in when the subsequent contacting front end side fully contacts and presses against the adhesive tissue reinforcement material 5. As a result, poor installation such as lifting and peeling is unlikely to occur across the entire surface of the adhesive tissue reinforcement material 5. Furthermore, even the tip of the automatic suture device 8... Figure 2As shown, it is hook-shaped. When the automatic stitcher 8 is clamped in, the part that contacts the front end is the opening 6, and the front end is also housed in the opening 6, thus allowing the automatic stitcher 8 to be completely clamped in. Furthermore, in... Figure 1 When the tissue reinforcement material installer 1, which consists of a platform section and a housing section, is shown, the automatic suture 8 can be removed from the tissue reinforcement material installer 1 by pulling the platform section toward the operator's hand while keeping the automatic suture 8 in the clamped state.

[0086] Figure 3 This is a schematic diagram illustrating an example of the tissue-reinforcing material installer of the present invention. Figure 3 In the form of, Figure 1 Based on the shape, a handle 9 is provided at the end of the front side. By providing the handle 9, fingers will not get wet when the tissue reinforcement material installer 1 is immersed in an aqueous solution, and the immersion operation can be performed easily. Furthermore, when the central part of the side of the handle 9 is concave, it is easier to grip the tissue reinforcement material installer 1 with fingers; and when anti-slip ribs are further formed on the side of the handle 9, it is easier to hold the tissue reinforcement material installer 1. In addition, by adopting a structure where the bottom of the recess 2 protrudes from the side at the end of the recess 2 on the operating hand side, the automatic suture can be gripped with greater force. When the handle 9 also has a notch 11 on the side of the recess 2, the front end is less likely to interfere with the handle 9 when gripping the automatic suture, thus further suppressing the lifting and peeling of the adhesive tissue reinforcement material at the front end.

[0087] exist Figure 3 In this configuration, the length of the protrusion 3 shortens from the front end towards the end of the recess 2 on the operator's side. By shortening the length of the protrusion 3 towards the operator's side, an inclination is created at the bottom of the recess 2. Therefore, with the clamping action of the automatic stapler, the adhesive tissue reinforcement material can be more reliably clamped from the operator's side to the front end, and the rebound force (elastic force) of the protrusion ensures that the adhesive tissue reinforcement material makes stronger contact with the front end of the automatic stapler. As a result, lifting and peeling of the adhesive tissue reinforcement material at the front end can be suppressed.

[0088] exist Figure 3 In this configuration, guide walls 10 are formed along both sides of the recess 2. By providing guide walls 10, the automatic stitcher is guided towards the recess 2, making it easier to clamp the automatic stitcher. Furthermore, by tilting the end of the guide wall 10 on the operator's hand side downwards towards the operator's hand, the automatic stitcher is less likely to get stuck, making it easier to clamp the automatic stitcher. Moreover, when the inner surface of the guide wall 10 tilts downwards towards the bottom of the recess 2, the automatic stitcher is guided towards the bottom of the recess 2 along the tilt during clamping, making it even easier to clamp the automatic stitcher.

[0089] exist Figure 3 In this configuration, the width of the bottom of the recess 2 widens towards the operator's hand side of the automatic stitcher; in other words, the housing portion widens towards the operator's hand side. This structure allows the automatic stitcher to more easily penetrate the recess.

[0090] In addition, Figure 3 In this configuration, the width between the bottom retaining grooves 7 used to mount the platform increases towards the operator's hand. By employing such bottom retaining grooves 7, the platform can be easily pulled out in its original state after the automatic suture is inserted. Therefore, the automatic suture is easy to remove, and the adhesive tissue reinforcement material 5 can be installed on the automatic suture more easily and in a shorter time.

[0091] Furthermore, such as Figure 3 As shown, when the adhesive tissue reinforcement material 5 is held in place of the tissue reinforcement material installer 1 as a tissue reinforcement material installation kit, the tissue reinforcement material installation kit preferably has a cover 12. By protecting the end of the tissue reinforcement material installation kit on the operator's side with the cover 12, accidental detachment of the adhesive tissue reinforcement material during transportation and storage can be prevented. The cover 12 is removed when the tissue reinforcement material installer 1 is immersed in an aqueous solution.

[0092] Next, the adhesive tissue reinforcement material paired with the tissue reinforcement material installer of the present invention will be described in detail.

[0093] The aforementioned adhesive tissue reinforcement material is a tissue reinforcement material that is fixed to an automatic suture device using adhesive force. There are no particular limitations on the aforementioned adhesive tissue reinforcement material, as long as it is a material formed by coating or laminating an adhesive substance onto an existing tissue reinforcement material, or a tissue reinforcement material that itself has adhesive properties. However, it is preferable to use an adhesive tissue reinforcement material formed by laminating a fabric layer made of bioabsorbable material and a sponge layer made of water-soluble polymer. When using such an adhesive tissue reinforcement material, the effects of the present invention can be maximized. Hereinafter, an adhesive tissue reinforcement material formed by laminating a fabric layer made of bioabsorbable material and a sponge layer made of water-soluble polymer will be described.

[0094] The aforementioned fabric-like layer serves as a tissue-strengthening material. Because it uses bioabsorbable materials, it is ultimately absorbed within the body after reinforcement is no longer needed, preventing long-term foreign body residue and ensuring high safety. The aforementioned sponge layer imparts adhesiveness to the adherent tissue-strengthening material; the aforementioned water-soluble polymer exhibits adhesiveness through its water content. Furthermore, here, "sponge-like" refers to a structure with numerous pores.

[0095] The aforementioned laminated integration refers to bonding two layers to a degree that makes it difficult for the fabric layer and the sponge layer to peel off even when force is applied. One method for laminating the fabric layer and the sponge layer is to freeze-dry the fabric after it has been floated on a water-soluble polymer solution that forms the raw material of the sponge layer. To improve the interfacial adhesion between the fabric layer and the sponge layer, it is preferable to use a plasma treatment device or similar method to perform a hydrophilic treatment on the fabric, thereby improving the permeability of the water-soluble polymer solution to the fabric.

[0096] Examples of the aforementioned bioabsorbent materials include synthetic absorbent polymers such as polyglycolic acid polymers, polylactide (D, L, DL bodies), glycolide-lactide (D, L, DL bodies) copolymers, glycolide-ε-caprolactone copolymers, lactide (D, L, DL bodies)-ε-caprolactone copolymers, poly(p-dioxanone), glycolide-lactide (D, L, DL bodies)-ε-caprolactone copolymers, and α-hydroxy acid polymers; and natural absorbent polymers such as collagen, gelatin, chitosan, and chitin. These can be used alone or in combination of two or more. For example, when using the aforementioned synthetic absorbent polymers as the aforementioned bioabsorbent materials, natural absorbent polymers can be used in combination. From the perspective of exhibiting high strength, polyglycolic acid, polylactic acid, or copolymers of lactic acid and caprolactone are preferred.

[0097] When using polyglycolic acid (a homopolymer or copolymer of glycolide) as the aforementioned bioabsorbable material, the preferred lower limit for the weight-average molecular weight of the glycolide is 30,000, and the preferred upper limit is 1,000,000. When the weight-average molecular weight of the glycolide is 30,000 or higher, it can more reliably strengthen tissues; when it is 1,000,000 or lower, it can further suppress foreign body reactions. A more preferred lower limit for the weight-average molecular weight of the glycolide is 50,000, and a more preferred upper limit is 300,000.

[0098] The shape of the aforementioned fabric layer is not particularly limited; for example, it can be any shape such as knitted fabric, woven fabric, non-woven fabric, or membrane. However, from the viewpoints of softness, breathability, and ease of passing through stitching staples, non-woven fabric is preferred.

[0099] When the aforementioned fabric layer is a nonwoven fabric, there is no particular limitation on the weight per unit area of ​​the nonwoven fabric, but the preferred lower limit is 3 g / m². 2 The preferred upper limit is 300g / m 2 The weight per unit area of ​​the aforementioned nonwoven fabric is 3 g / m². 2 At the above levels, it can more reliably strengthen the tissue, at 300g / m². 2 The following steps can further improve the adhesion to tissues. A more preferred lower limit for the weight per unit area of ​​the aforementioned bioabsorbent nonwoven fabric is 5 g / m².2 The preferred upper limit is 100g / m 2 .

[0100] There are no particular limitations on the method for manufacturing the above-mentioned nonwoven fabric. For example, currently known methods such as electrospinning deposition, meltblowing, needle punching, spunbonding, flash spinning, hydroentangling, air-laid web forming, thermal bonding, resin bonding, and wet bonding can be used.

[0101] Examples of water-soluble polymers include natural polymers such as polysaccharide-based materials and protein-based materials, and synthetic polymers such as polyacrylic acid and polyvinyl alcohol. Since the tissue-reinforcing material used in automated suture devices is implanted within the body, materials with high biocompatibility are required. Among these, polysaccharide-based or protein-based materials are preferred because they are less prone to displacement during automated suture device operation and possess adhesive strength sufficient for easy peeling at the end of suturing. Examples of polysaccharide-based materials include hydroxypropyl methylcellulose, amylopectin, sodium alginate, and carboxymethyl cellulose; examples of protein-based materials include gelatin, collagen peptides, and water-soluble elastin.

[0102] It is desirable that the viscosity of the aforementioned water-soluble polymer, when forming a 2% aqueous solution, is above 1 mPa·s and below 500 mPa·s. By using water-soluble polymers within the above range, the sponge layer formed exhibits moderate softness, and after being soaked in water, it demonstrates moderate adhesiveness, making it easy to bond with an automatic sewing machine.

[0103] The aforementioned sponge layer is preferably a freeze-dried body.

[0104] By freeze-drying to form a sponge layer, a sponge layer can be formed without the use of a pore-forming agent. Therefore, it is not necessary to remove the pore-forming agent, and a sponge layer with high material purity can be formed. There are no particular limitations on the freeze-drying method; currently known methods can be used.

[0105] The thickness of the aforementioned sponge layer is preferably 0.3 mm or more and 3.0 mm or less.

[0106] By ensuring the thickness of the sponge layer is within the aforementioned range, deviation can be further suppressed during the operation of the automatic suture machine, and the adhesive force can be easily adjusted to a suitable level that allows for easy peeling after suturing. More preferably, the thickness of the sponge layer is 0.3 mm or more and 0.5 mm or less. In the case of forming the sponge layer through freeze-drying, the thickness of the sponge layer can be adjusted according to the amount of water-soluble polymer solution impregnated in the fabric layer. Furthermore, the thickness of the sponge layer mentioned here refers to a value of 1 cm² using a dial indicator (e.g., the SMD-565J-L manufactured by Teclock). 2The thickness of the sponge layer is obtained by measuring the entire area at intervals and averaging the results.

[0107] The density of the aforementioned sponge layer is not particularly limited, but is preferably 0.1 g / cm³. 3 Above and 0.7g / cm 3 the following.

[0108] By setting the density of the sponge layer to the aforementioned range, it is possible to further suppress deviations when operating the automatic suture machine, and to easily adjust to a moderate adhesive force that allows for easy peeling after suturing.

[0109] The shape of the aforementioned adhesive tissue reinforcement material corresponds to the shape of the location where the automatic suture device is installed.

[0110] The aforementioned adhesive tissue reinforcement material is attached to the automatic suture device via an adhesive attachment, thus eliminating the need for a cylindrical shape as required by existing reinforcement materials for fixation. As a result, the reinforcement material is less likely to get stuck during catheter insertion, and the diameter of the automatic suture device remains almost unchanged even with the reinforcement material installed, allowing for the passage of finer catheters.

[0111] The preferred adhesion strength of the above-mentioned adhesive tissue reinforcement material when attached to an automatic suture device is 5 N / cm. 2 above.

[0112] By ensuring the adhesive strength when attached to the automatic suture device is within the aforementioned range, deviation during operation of the automatic suture device can be further suppressed. More preferably, the adhesive strength is 10 N / cm. 2 That's all. There is no particular upper limit to the adhesive strength described above, but from the viewpoint of facilitating peeling after the suture is completed, 30 N / cm is preferred. 2 The following methods can be used to determine the aforementioned bond strength.

[0113] Cut the adhesive tissue reinforcement material into pieces 8mm wide and 40mm long. Apply only a 10mm length to the abutment side of an automatic stapler (such as the Ethicon ENDOPATH ECHELON FLEX 60 stapler) pre-soaked in saline solution, pressing for 3 minutes to ensure adhesion. Next, mount the handle of the automatic stapler to the lower chuck of a tensile testing machine (such as the AG-X Plus automatic plotting precision universal testing machine, manufactured by Shimadzu Corporation), and mount the end of the adhesive tissue reinforcement material extending from the automatic stapler to the upper chuck of the tensile testing machine. Then, perform a tensile test at a tensile speed of 100mm / min, and take the maximum load at which displacement occurs as the bond strength.

[0114] There is no particular limitation on the manufacturing method of the above-mentioned adhesive tissue reinforcement material. For example, it can be manufactured according to the above method, or it can be obtained by pouring a water-soluble polymer solution onto the fabric after the fabric is applied to the bottom surface, so that the water-soluble polymer solution does not flow into the lower surface of the fabric, and then using freeze drying to form a sponge layer.

[0115] Invention Effects

[0116] According to the present invention, it is possible to provide a tissue reinforcement installer that can correctly and easily install an adhesive tissue reinforcement material into an automatic suture device in a short time, and a tissue reinforcement material installation kit using the tissue reinforcement material installer. Attached Figure Description

[0117] Figure 1 This is a schematic diagram illustrating an example of the tissue-strengthening material installer of the present invention.

[0118] Figure 2 This is a schematic diagram illustrating the use of the tissue reinforcement material installer of the present invention.

[0119] Figure 3 This is a schematic diagram illustrating an example of the tissue reinforcement material mounting kit of the present invention. Detailed Implementation

[0120] The present invention will now be described in more detail with reference to figures, but the present invention is not limited to these forms.

[0121] (Example 1)

[0122] (1) Manufacturing of adherent tissue-reinforcing materials

[0123] Add distilled water to hydroxypropyl methylcellulose (HPMC) (viscosity grade 6: AN6, 2% solution viscosity: 5.1 mPa / s, manufactured by Mitsubishi Chemical Foods Co., Ltd.) to prepare an 8% by weight HPMC aqueous solution. Add 10g to the culture dish. Next, cut the fibrous layer into... A sheet of polyglycolic acid (PGA) nonwoven fabric was floated on a petri dish containing an aqueous solution of HPMC. After confirming that the HPMC solution had thoroughly soaked the sheet of nonwoven fabric, the petri dish was placed in a freezer at -80°C for 15 minutes to freeze the HPMC solution. The frozen HPMC solution was then dried using a vacuum freeze dryer to form a sponge layer (adhesive layer) of HPMC on the nonwoven fabric, thus creating an adhesive tissue reinforcement material.

[0124] (2) Manufacturing of tissue reinforcement material installers and adhesive tissue reinforcement material installation kits.

[0125] By injecting and molding polyethylene, a product was made. Figure 1 The housing portion has a U-shape with two sets of fixing grooves and one platform mounting groove. Here, the width of each fixing groove is 0.5mm, the width of the bottom retaining groove is 3.5mm, and the dimensions inside the U-shape are 11mm high × 9mm wide × 70mm long. On the other hand, it is manufactured by injection molding with silicone (manufactured by Asahi Kasei Wacker Silicon Co., Ltd., SILPURAN (registered trademark) 8020 / 40), resulting in a surface with 16 pieces / cm on both sides. 2 The density has a bottom recess with a brush-like protrusion 2 mm in length, a width of 9 mm, and a length of 60 mm, and a platform portion with a width of 3.5 mm on both long sides for mounting in the bottom retaining groove. Next, the obtained platform portion is inserted into the bottom retaining groove of the obtained housing portion to obtain the tissue reinforcement material installer. At this time, the platform portion is inserted 60 mm from the front end (inlet side) of the housing portion, and an opening with a width of 9 mm and a length of 10 mm is provided on the closed side of the housing portion.

[0126] Then, the obtained adhesive tissue reinforcement material is cut to a size of 10mm wide × 60mm long and held in the fixing groove with the adhesive layer facing upward as a tissue reinforcement material installation kit.

[0127] (3) Installation of automatic sewing machine

[0128] The obtained adhesive tissue reinforcement material mounting kit was immersed in physiological saline (Otsuka Raw Food Injection, manufactured by Otsuka Pharmaceutical) for 5 seconds. Then as follows... Figure 2 As shown, the automatic stapler (Ethicon, ENDOPATH ECHELON FLEX 60 stapler) is inserted from the open side of the housing and clamped between the recesses for 5 seconds. Then, while keeping the automatic stapler clamped, the platform section is pulled out of the housing, releasing the automatic stapler from the tissue reinforcement installer. The tissue reinforcement installation site of the automatic stapler is checked, and it is found that the adhesive tissue reinforcement is completely installed to the front end without deviation from the designated position. Furthermore, the time from soaking in saline solution to completion of installation is approximately 20 seconds.

[0129] (Example 2)

[0130] By injecting polypropylene and molding it, a product with... Figure 3The housing portion is U-shaped, comprising a handle, two sets of retaining grooves, one set of bottom retaining grooves, and two sets of guide walls. Here, the width of each retaining groove is 0.5 mm. Furthermore, the thickness direction length of the bottom retaining groove is 2 mm at the front end and 2.4 mm at the operator's hand end. The width within the U-shape, including the portion forming the retaining grooves and the guide walls, is 17 mm at the front end and 17.4 mm at the operator's hand end, thus creating a shape that widens towards the operator's hand. Further, the guide walls have a height of 2 mm and a length of 34 mm, with an inner surface inclined portion having a 30° inclination angle on the inner surface and an operator's hand inclined portion having a 30° inclination angle at the operator's hand end.

[0131] On the other hand, by injection molding silicone (manufactured by Asahi Kasei Wacker Silicone Co., Ltd., SILPURAN (registered trademark) 8020 / 40), a product with 9 / cm on both bottom surfaces was manufactured. 2 The device has a brush-like protrusion with a maximum length of 2.2 mm, a concave bottom with a width of 9 mm × length of 52 mm × bottom thickness of 1 mm, and a platform portion with a width of 3.5 mm on both long sides for mounting to the aforementioned bottom retaining groove. At this time, the length of the protrusion is changed to 2.2 mm, 1.95 mm, and 1.7 mm from the front end side towards the operator's hand side, thereby shortening its length towards the operator's hand side. Furthermore, each length interval is 1 / 3 of the length of the bottom.

[0132] Next, a tissue reinforcement material installer is obtained by inserting the obtained platform portion into the aforementioned platform portion mounting groove of the obtained housing portion. At this time, an opening of approximately 9mm wide and 10mm long is provided on the front end side of the recess. Then, an adhesive-type tissue reinforcement material cut to dimensions of 10mm wide and 60mm long is held in the fixing groove with the adhesive layer facing upwards as a tissue reinforcement material mounting kit.

[0133] The obtained tissue reinforcement material installation kit was operated in the same manner as in Example 1. When installing the adhesive tissue reinforcement material onto the automatic suture device, the adhesive tissue reinforcement material was completely installed to the front end without deviation from the designated position. Furthermore, the time from immersion in physiological saline to completion of installation was approximately 15 seconds.

[0134] (Comparative Example 1)

[0135] The adhesive tissue reinforcement material prepared in Example 1 was cut according to the shape of the automatic suture device. Then, it was immersed in physiological saline for 5 seconds and adhered to the designated positions (2 locations) on the automatic suture device. The adhesive tissue reinforcement material was installed by pressing with a 2mm thick foamed polyethylene sheet for 5 seconds. Although the adhesive tissue reinforcement material was installed without deviation from the designated position, the time from immersion in physiological saline to completion of installation was approximately 90 seconds.

[0136] (Comparative Example 2)

[0137] Except for lacking the aforementioned brush-like protrusions, the adhesive tissue reinforcement material installation kit was fabricated using the same method as in Example 1, and the adhesive tissue reinforcement material was installed. As a result, the time from immersion in saline solution to completion of installation was the same as in Example 1, and it was also possible to install it from the specified position without deviation, but some lifting occurred at the front end.

[0138] Industrial availability

[0139] According to the present invention, it is possible to provide a tissue reinforcement installer that can correctly and easily install an adhesive tissue reinforcement material into an automatic suture device in a short time, and a tissue reinforcement material installation kit using the tissue reinforcement material installer.
