Description

Technical Field

[0001] This invention relates to the field of medical fascia suturing technology, and more specifically, to a fascia stapler and its method of use. Background Technology

[0002] After the medical procedure, the fascia needs to be sutured, followed by suturing the corresponding skin surface. Therefore, the effectiveness of fascial suturing is crucial for the healing and recovery of the affected area after surgery.

[0003] However, due to the structural characteristics of the fascia and the special location of the fascia, the existing fascial suturing results are not ideal, making it inconvenient to suture the fascia during surgery, resulting in poor fascial suturing effects and affecting the patient's postoperative recovery. Summary of the Invention

[0004] The present invention aims to solve the problem of inconvenience in suturing fascia during surgery, which leads to poor fascia suturing results.

[0005] To address the above problems, the present invention provides a fascia stapler, comprising:

[0006] A central shaft has an insertion end at one end. Two recessed structures are formed in parallel at the central shaft behind the insertion end. Guide grooves are formed on both sides of the central shaft, and the guide grooves are connected to the recessed structures one by one. A connecting hole is formed inside the insertion end. The connecting hole is a U-shaped through hole, and its two ends are connected to one of the recessed structures. A release groove is formed on the insertion end. The release groove extends from one side of the insertion end, around the insertion end, to the other side of the insertion end. The release groove connects the connecting hole to the outer surface of the insertion end. The width of the release groove is smaller than the diameter of the connecting hole.

[0007] Two needles are respectively positioned in corresponding guide grooves, and the needles are used to be inserted into the connecting holes from the guide grooves; and

[0008] A guide sleeve, the diameter of which is greater than the width of the release groove, one end of which is used to pass from one needle tube through the connecting hole into another needle tube; the other end of which is connected to the suture.

[0009] The suture is used to extend from the release groove.

[0010] Optionally, the two recessed structures are symmetrically arranged about the central axis, and the release groove connects the two recessed structures.

[0011] Alternatively, the recessed structure passes through the central axis from top to bottom, and the two recessed structures are recessed into the central axis from the left and right sides respectively.

[0012] Optionally, the guide sleeve is a metal conduit, and the guide sleeve is adapted to undergo plastic deformation in the connection hole.

[0013] Optionally, the fascial anastomosis device further includes a sleeve fitted over the central axis, the sleeve being used to cover the two recessed structures.

[0014] Optionally, the fascia anastomosis device further includes two pushers, and the needle tubes are inserted into the corresponding pushers one by one. Each pusher has an insertion hole, which communicates with the needle tubes and is used for the passage of the guide sleeve.

[0015] Optionally, the fascia stapler further includes a fixation seat, which is disposed on the outer surface of the central shaft and connected to the central shaft. A protruding structure is connected to the outer surface of the sleeve, which is placed between the central shaft and the fixation seat. A limiting groove is formed on the top surface of the fixation seat, which penetrates the bottom surface of the fixation seat. The limiting groove is F-shaped and arranged along the axial direction of the central shaft. The front end of the limiting groove communicates with the front end of the fixation seat. The protruding structure is used to move within the limiting groove.

[0016] Optionally, the fixing seat is a sleeve structure, the fixing seat is sleeved outside the central shaft, and the fixing seat has a sliding groove on both sides. The pusher seat is installed in the corresponding sliding groove, and the pusher seat is used to move back and forth along the sliding groove.

[0017] Optionally, the central shaft is a tubular structure, and the main through hole inside the central shaft extends from the other end of the central shaft to the two recessed structures. The main through hole communicates with the two recessed structures, and the side wall of the fixing seat is provided with an observation window. The main through hole communicates with the observation window.

[0018] The fascia stapler also includes:

[0019] An adjusting piece is disposed within the connecting hole, covering the connection between the connecting hole and the release groove. The long side of the adjusting piece is arranged along the extending direction of the connecting hole. One end of the long side of the adjusting piece is fixed within the connecting hole, and the other end of the long side of the adjusting piece is disposed at the end of the connecting hole. The adjusting piece has a tear line, which is arranged along the extending direction of the release groove. The stitching line is used to disconnect the adjusting piece along the tear line.

[0020] Two traction wires, one end of each traction wire is connected from top to bottom to the other end of the long side of the adjusting plate, the two traction wires are spaced apart, the guide sleeve is used to pass between the two traction wires, and the other end of each traction wire passes through the side wall of the connecting hole and extends out of the central shaft along the main through hole;

[0021] Two springs, one in each direction, are fitted over the traction line. Each spring is positioned within the connecting hole, with one end abutting against the other end of the long side of the adjusting plate and the other end abutting against the side wall of the connecting hole.

[0022] Two pull rings are connected one-to-one with the other end of the corresponding traction line.

[0023] In addition, the present invention also provides a method of using a fascia stapler, the method of using the fascia stapler comprising:

[0024] Move the syringe behind the recessed structure;

[0025] Insert the insertion end of the central shaft into the opening of the fascia;

[0026] Place the fascia near the opening into the corresponding concave structure;

[0027] The two needles are moved along the guide groove and pass through the fascia in the corresponding recessed structure into the connecting hole;

[0028] One end of the guide sleeve is inserted from one needle tube through the connecting hole into another needle tube, and the guide sleeve extends out from the other needle tube, wherein the other end of the guide sleeve is connected to the suture.

[0029] Only the guide sleeve is removed from the needle tube, while the suture remains in both needle tubes;

[0030] Pull the two needles out of the fascia;

[0031] Withdraw the insertion tip from the opening in the fascia;

[0032] Tie a knot in the suture.

[0033] Optionally, before inserting the insertion end of the central shaft into the opening of the fascia, the recessed structure is covered with a sleeve.

[0034] After inserting the insertion end of the central shaft into the opening of the fascia, the sleeve is moved backward along the central shaft so that the fascia near the opening is placed in the corresponding recessed structure.

[0035] Compared with the prior art, the present invention has the following technical effects:

[0036] In this invention, it is only necessary to insert the insertion tip into the opening of the fascia and place the fascia on both sides of the opening in the corresponding recessed structure. Then, the needle tube is inserted into the connecting hole through the fascia in the recessed structure. Next, the guide sleeve containing the suture is inserted from one needle tube through the connecting hole into another needle tube. Then, the guide sleeve is pulled out of the needle tube. In this process, taking advantage of the fact that the diameter of the guide sleeve is larger than the width of the release groove, and taking advantage of the connection between the guide sleeve and the suture, the suture can only move along the connecting hole with the guide sleeve and enter the other needle tube. This allows the suture to pass through the fascia on both sides of the opening at the same time. Furthermore, during the process of pulling out the guide sleeve, since the guide sleeve is in the needle tube and the connecting hole, rather than in direct contact with the fascia, there is no damage to the fascia when pulling out the guide sleeve. Therefore, it is not necessary to be too careful, and the speed of pulling out the guide sleeve can be increased, thereby improving the suturing efficiency. Then, utilizing the characteristics that "the release groove extends from one side of the insertion end, around the insertion end, to the other side of the insertion end, and the release groove connects the connecting hole to the outer surface of the insertion end" and "the suture can extend from the release groove," the suture separates from the insertion end through the release groove from the connecting hole during the process of the insertion end withdrawing from the opening. This ensures that the suture still passes through the fascia at the opening, thus avoiding interference with the suture during the withdrawal of the insertion end. For example, it can prevent the insertion end from detaching the suture from a fascia at the opening, thereby ensuring that the suturing effect of the previous suture remains unchanged. In this way, the fascial anastomosis device of the present invention achieves rapid and accurate suturing of the fascia without damaging the fascia near the opening during the process, providing a strong guarantee for subsequent wound healing, thereby solving the problem of inconvenient fascial suturing during surgery and resulting in poor fascial suturing effect.

[0052] To solve the above technical problems, see [link to relevant documentation]. Figures 1 to 7 The present invention provides a fascia stapler, comprising:

[0053] A central shaft 100 has an insertion end 110 at one end. Two recessed structures 120 are formed in parallel at the central shaft 100 behind the insertion end 110. Guide grooves 130 are formed on both sides of the central shaft 100, and the guide grooves 130 are connected to the recessed structures 120 one by one. A connecting hole 111 is formed in the insertion end 110. The connecting hole 111 is a U-shaped through hole, and its two ends are connected to one of the recessed structures 120. A release groove 112 is formed in the insertion end 110. The release groove 112 extends from one side of the insertion end 110, around the insertion end 110, to the other side of the insertion end 110. The release groove 112 connects the connecting hole 111 to the outer surface of the insertion end 110. The width of the release groove 112 is smaller than the diameter of the connecting hole 111.

[0054] Two needle tubes 200 are respectively disposed in corresponding guide grooves 130, and the needle tubes 200 are used to be inserted into the connecting holes 111 from the guide grooves 130; and

[0055] Guide sleeve 210, the diameter of which is greater than the width of the release groove 112, one end of which is used to enter from one needle tube 200 through the connection hole 111 into another needle tube 200, and the other end of which is connected to the suture 211.

[0056] The suture 211 is used to extend from the release groove 112.

[0057] In use, move the needle tube 200 to the rear of the recessed structure 120 to prevent the needle tube 200 from obstructing the fascia 600 at the opening from entering the recessed structure 120. Insert the insertion end 110 of the central shaft 100 into the opening of the fascia 600; place the fascia 600 near the opening in the corresponding recessed structure 120; move the two needle tubes 200 along the guide groove 130 and through the fascia 600 in the corresponding recessed structure 120 into the connecting hole 111.

[0058] One end of the guide sleeve 210 is inserted from one needle tube 200 through the connecting hole 111 into another needle tube 200, and the other end of the guide sleeve 210 is connected to the suture 211. During this process, the guide sleeve 210 can be pushed manually or mechanically, such as with a suture sleeve 300, to allow one end of the guide sleeve 210 to enter from one needle tube 200 through the connecting hole 111 into another needle tube 200. For example, in... Figure 6 The arrows indicate the direction of passage of the guide sleeve 210. Here, the diameter of the guide sleeve 210 is larger than the width of the release groove 112, so that during the process of pushing the guide sleeve 210, the guide sleeve 210 can only move along the connecting hole 111 and eventually enter another needle tube 200, thereby enabling the suture 211 at the other end of the guide sleeve 210 to pass through the fascia 600 on both sides of the opening at the same time.

[0059] The guide sleeve 210 extends out from the other needle tube 200, and the guide sleeve 210 is withdrawn from the needle tube 200;

[0060] Pull the two needles 200 out of the fascia 600 and remove the insertion end 110 from the opening of the fascia 600;

[0061] Using the needle tube 200 to pass through the fascia 600 at the opening, the suture 211 passing through the needle tube 200 also passes through the fascia 600 on both sides of the opening along with the guide sleeve 210, thereby suturing the fascia 600 on both sides of the opening. Then, the guide sleeve 210 is withdrawn from the needle tube 200. Taking advantage of the fact that the suture 211 can extend out of the release groove 112, the insertion end 110 is withdrawn from the opening of the fascia 600, so that the suture 211 is released from the release groove 112.

[0062] Finally, the suture 211 at the opening is knotted to achieve a good suturing effect on the fascia 600 on both sides of the opening.

[0063] Thus, it is only necessary to insert the insertion tip 110 into the opening of the fascia 600, and place the fascia 600 on both sides of the opening into the corresponding recessed structure 120. Then, the needle tube 200 is inserted into the connecting hole 111 through the fascia 600 in the recessed structure 120. Next, one end of the guide sleeve 210 is inserted from one needle tube 200 through the connecting hole 111 into another needle tube 200. Then, the guide sleeve 210 is withdrawn from the needle tube 200, so that the suture 211 connected to the guide sleeve 210 also moves along the above trajectory. During this process, the guide sleeve 210 is used to... The diameter of the guide sleeve 210 is larger than the width of the release groove 112, which allows the suture 211 inside the guide sleeve 210 to move only along the connecting hole 111 and enter another needle tube 200. This allows the suture 211 to pass through the fascia 600 on both sides of the opening at the same time. Furthermore, during the withdrawal of the guide sleeve 210, since the guide sleeve 210 is in the needle tube 200 and the connecting hole 111, rather than in direct contact with the fascia 600, there is no damage to the fascia 600 when the guide sleeve 210 is withdrawn. Therefore, it is not necessary to be too careful, and the speed of withdrawing the guide sleeve 210 can be increased, thereby improving the suturing efficiency. Then, utilizing the characteristics that "the release groove 112 extends from one side of the insertion end 110 around the insertion end 110 to the other side of the insertion end 110, and the release groove 112 connects the connecting hole 111 with the outer surface of the insertion end 110" and "the suture 211 can extend out from the release groove 112", the suture 211 is released from the connection hole 111 through the release groove 112 and detached from the insertion end 110 during the process of the insertion end 110 withdrawing from the opening. This allows the suture 211 to remain in the state of simultaneously passing through the fascia 600 at the opening, thereby avoiding interference with the suture 211 during the withdrawal of the insertion end 110. For example, it can prevent the insertion end 110 from detaching the suture 211 from a fascia 600 at the opening, thus ensuring that the suturing effect of the previous suture 211 remains unchanged. In this way, the fascia 600 can be quickly and accurately sutured using the fascia anastomosis device of the present invention, and the fascia 600 near the opening will not be damaged during the process, which provides a strong guarantee for subsequent wound healing. This solves the problem that it is inconvenient to suture the fascia 600 during surgery, resulting in poor fascia 600 suturing effect.

[0064] See Figures 1 to 7 Furthermore, the two recessed structures 120 are symmetrically arranged about the axis of the central axis 100, and the release groove 112 connects the two recessed structures 120.

[0065] This arrangement ensures that the fascia 600 on both sides of the opening is positioned within the recessed structure 120, allowing the needle 200 to pass through the fascia 600 on both sides of the opening. Consequently, the suture 211 sutures the fascia 600 on both sides of the opening, resulting in a better suturing effect at the opening of the fascia 600.

[0066] Alternatively, the recessed structure 120 may penetrate the central axis 100 from top to bottom, and the two recessed structures 120 may be recessed into the central axis 100 from the left and right sides respectively.

[0067] The central axis 100 is penetrated from top to bottom through the recessed structure 120, so that as much of the fascia 600 at the opening as possible is within the recessed structure 120. This reduces the deformation of the fascia 600 on both sides of the opening when the insertion tip 110 is inserted, ensuring that the insertion position of the needle 200 into the fascia 600 is as similar as possible to the insertion position of the needle 200 into the fascia 600 when the opening is closed. This guarantees the effectiveness of the subsequent suturing of the opening by the suture 211.

[0068] See Figures 1 to 7 Furthermore, the guide sleeve 210 is a metal conduit, and the guide sleeve 210 is adapted to undergo plastic deformation in the connection hole 111.

[0069] The metal conduits here can be made of titanium or stainless steel.

[0070] The metal conduit here can also be formed by wrapping metal foil around the suture 211. For example, it can be a guide sleeve 210 formed by wrapping tin foil around the suture 211, or it can be a metal conduit formed by wrapping aluminum foil around the suture 211. Of course, the metal conduit here can also be an injection-molded metal conduit, which can be reused.

[0071] The guide sleeve 210 is a metal conduit, and the weight of the metal conduit is greater than that of the suture 211, thereby guiding the suture 211 to move along the needle tube 200 so that the suture 211 can move quickly within the needle tube 200.

[0072] In addition, the guide sleeve 210 is adapted to undergo plastic deformation in the connecting hole 111, so that the guide sleeve 210 can deform when passing through the needle tube 200, the connecting hole 111 and their docking point, so that the guide sleeve 210 can guide the suture 211 smoothly through the U-shaped connecting hole 111 and change direction, and finally extend out from another needle tube 200.

[0073] See Figures 1 to 7 Furthermore, the fascia stapler also includes a sleeve 300, which is sleeved outside the central shaft 100 and is used to cover the two recessed structures 120.

[0074] Before inserting the insertion end 110 of the central shaft 100 into the opening of the fascia 600, the recessed structure 120 is covered with a sleeve 300.

[0075] After inserting the insertion end 110 of the central shaft 100 into the opening of the fascia 600, the sleeve 300 is moved backward along the central shaft 100 so that the fascia 600 near the opening is placed in the corresponding recessed structure 120.

[0076] Without the sleeve 300 covering the recessed structure 120, the irregular shape of the recessed structure 120 could damage the fascia 600 at the opening when the insertion end 110 enters and exits the fascia 600. Therefore, the sleeve 300 is used to cover the recessed structure 120 during the insertion and exit of the insertion end 110 at the fascia 600 opening, effectively preventing damage to the fascia 600 near the opening due to the irregular shape of the recessed structure 120. This promotes wound healing at the fascia 600 opening.

[0077] See Figures 1 to 7 Furthermore, the fascia anastomosis device also includes two push seats 220, and the needle tubes 200 are inserted into the corresponding push seats 220 one by one. The push seats 220 have insertion holes 221, which are connected to the needle tubes 200. The insertion holes 221 are used for the guide sleeves 210 to pass through.

[0078] By having medical staff manually push the pusher seat 220 back and forth, the needle 200 can be easily inserted into or removed from the fascia 600 next to the opening, thereby improving the efficiency of the needle 200. Furthermore, the insertion port 221 communicates with the needle 200, allowing the guide sleeve 210 to extend from the insertion port 221.

[0079] See Figures 1 to 7 Furthermore, the fascia stapler also includes a fixation base 400, which is disposed on the outer surface of the central shaft 100 and connected to the central shaft 100. A protrusion structure 310 is connected to the outer surface of the sleeve 300. The sleeve 300 is placed between the central shaft 100 and the fixation base 400. A limiting groove 410 is formed on the top surface of the fixation base 400. The limiting groove 410 penetrates the bottom surface of the fixation base 400. The limiting groove 410 is F-shaped and arranged along the axial direction of the central shaft 100. The front end of the limiting groove 410 communicates with the front end of the fixation base 400. The protrusion structure 310 is used to move in the limiting groove 410.

[0080] The limiting groove 410 is F-shaped and arranged along the axial direction of the central axis 100, meaning that the vertical line of the F-shape is arranged along the axial direction of the central axis 100. The front end of the limiting groove 410 communicates with the front end of the fixing seat 400, allowing the protruding structure 310 to enter the limiting groove 410 from the front end of the fixing seat 400. When the sleeve 300 needs to cover the recessed structure 120, the protruding structure 310 can move along the vertical groove of the limiting groove 410 into the horizontal groove at the front of the F-shape, that is, into the "-" shaped groove at the bottom of the F-shape. This horizontal groove at the front of the F-shape restricts the protruding structure 310, thus keeping the sleeve 300 covering the recessed structure 120. In the case where it is necessary to expose the recessed structure 120 outside the sleeve 300, the protruding structure 310 is moved from the front horizontal groove of the F-shape along the vertical groove of the F-shape to the rear horizontal groove of the F-shape, that is, the "-" shaped groove at the top of the F-shape, thereby restricting the protruding structure 310 from moving axially along the central axis 100, so that the sleeve 300 is placed behind the recessed structure 120, and the recessed structure 120 is exposed outside the sleeve 300; conversely, when it is necessary to cover the recessed structure 120, the protruding structure 310 is moved from the rear horizontal groove of the F-shape along the vertical groove of the F-shape to the front horizontal groove of the F-shape, so that the sleeve 300 covers the recessed structure 120.

[0081] Alternatively, the fixed seat 400 is a sleeve structure, which is sleeved on the outside of the central shaft 100. The fixed seat 400 has a sliding groove 420 on both sides, and the pusher seat 220 is installed in the corresponding sliding groove 420. The pusher seat 220 is used to move back and forth along the sliding groove 420.

[0082] The pusher seat 220 is installed and fixed via the slide groove 420, and is bolted to the outside of the central shaft 100 using a sleeve structure. The slide groove 420 also guides the pusher seat 220, allowing medical personnel to quickly extend and retract the needle tube 200 simply by pushing the pusher seat 220 along the slide groove 420.

[0083] See Figures 1 to 7 Furthermore, the central shaft 100 is a tubular structure, and the main through hole 140 inside the central shaft 100 extends from the other end of the central shaft 100 to the two recessed structures 120, and the main through hole 140 communicates with the two recessed structures 120.

[0084] An endoscope can be inserted into the main through-hole 140 from the other end of the central shaft 100.

[0085] The main through-hole 140 within the central shaft 100 extends from the other end of the central shaft 100 to the two recessed structures 120. The main through-hole 140 communicates with the two recessed structures 120, allowing the endoscope to enter the recessed structure 120 along the main through-hole 140. This allows observation of the guide sleeve 210 entering the other needle tube 200, enabling corresponding adjustments to the extension and retraction of the other needle tube 200 and the guide sleeve 210 to ensure accurate entry of the guide sleeve 210 into the other needle tube 200. Alternatively, the endoscope can be inserted into the main through-hole 140 through a pre-set observation window 430 located on the side wall of the fixing base 400. The observation window 430 is equipped with a cap, which normally covers the observation window 430.

[0086] See Figure 4 Furthermore, the fascia stapler also includes:

[0087] An adjusting piece 510 is disposed within the connecting hole 111, covering the portion of the connecting hole 111 that communicates with the release groove 112. The long side of the adjusting piece 510 is arranged along the extending direction of the connecting hole 111. One end of the long side of the adjusting piece 510 is fixed within the connecting hole 111, and the other end of the long side of the adjusting piece 510 is disposed at the end of the connecting hole 111. The adjusting piece 510 has a tear line 511, which is arranged along the extending direction of the release groove 112. The suture line 211 is used to disconnect the adjusting piece 510 along the tear line 511.

[0088] Two traction wires 520, one end of each traction wire 520 is connected from top to bottom to the other end of the long side of the adjusting piece 510, and the two traction wires 520 are spaced apart. The guide sleeve 210 is used to pass between the two traction wires 520. The other end of each traction wire 520 passes through the side wall of the connecting hole 111 and extends out of the central shaft 100 along the main through hole 140.

[0089] Two springs 530 are fitted onto the outside of the traction line 520, one in each case. Each spring 530 is positioned inside the connecting hole 111. One end of each spring 530 abuts against the other end of the long side of the adjusting piece 510, and the other end abuts against the side wall of the connecting hole 111.

[0090] Two pull rings 540 are connected to the other end of the corresponding traction line 520.

[0091] When the guide sleeve 210 cannot smoothly enter another needle tube 200, the pull ring 540 can be controlled to cause the corresponding traction line 520 to drive the other end of the long side of the adjusting piece 510 to swing left and right in the connecting hole 111, thereby allowing the guide sleeve 210 to swing left and right. When the pull ring 540 is released, the spring 530, with one end pressing against the other end of the long side of the adjusting piece 510 and the other end pressing against the side wall of the connecting hole 111, will reset the other end of the long side of the adjusting piece 510, preventing the adjusting piece 510 from interfering with the movement of the guide sleeve 210. Here, the guide sleeve 210 is placed between two traction lines 520, and one end of each traction line 520 is connected from top to bottom to the other end of the long side of the adjusting piece 510. By pulling the pull ring 540, the guide sleeve 210 can swing up and down at the adjusting piece 510, thus enabling the guide sleeve 210 to swing left and right. If the guide sleeve 210 cannot be accurately inserted into another needle tube 200, the endoscope can be inserted into the recessed structure 120 along the main through hole 140. The endoscope is used to observe the docking of the guide sleeve 210 and the other needle tube 200. By controlling the corresponding pull ring 540, the traction line 520 drives the corresponding adjustment piece 510 to adjust the position of the guide sleeve 210 in the front, back, left, and right directions. The extension and retraction position of the end of the needle tube 200 can also be adjusted at the same time, so that the guide sleeve 210 can be accurately inserted into the needle tube 200.

[0092] In addition, after the guide sleeve 210 accurately enters another needle tube 200 and after the guide sleeve 210 is withdrawn from all needle tubes 200, a tear line 511 is provided by the adjusting plate 510. The tear line 511 is set along the extension direction of the release groove 112. The suture line 211 is used to break the adjusting plate 510 along the tear line 511, so that the suture line 211 can be smoothly released from the release groove 112, realizing the separation of the suture line 211 from the insertion end 110.

[0093] See Figure 8 In addition, the present invention also provides a method of using a fascia stapler, the fascia stapler comprising:

[0094] Move the needle 200 behind the recessed structure 120 to prevent the needle 200 from obstructing the fascia 600 at the opening from entering the recessed structure 120.

[0095] Insert the insertion end 110 of the central shaft 100 into the opening of the fascia 600;

[0096] Place the fascia 600 near the opening into the corresponding concave structure 120;

[0097] The two needles 200 are moved along the guide groove 130 and pass through the fascia 600 in the corresponding recessed structure 120 into the connecting hole 111;

[0098] One end of the guide sleeve 210 is inserted from one needle tube 200 through the connecting hole 111 into another needle tube 200, and the other end of the guide sleeve 210 is connected to the suture 211. During this process, the guide sleeve 210 can be pushed manually or mechanically, such as using a suture 211 sleeve 300, to allow the guide sleeve 210 to move from one needle tube 200 through the connecting hole 111 into another needle tube 200. Here, the diameter of the guide sleeve 210 is larger than the width of the release groove 112, so that during the pushing process, the guide sleeve 210 can only move along the connecting hole 111 and eventually enter the other needle tube 200, thus ensuring that the suture 211 connected to the other end of the guide sleeve 210 also passes through the fascia 600 on both sides of the opening.

[0099] The guide sleeve 210 extends out from the other needle tube 200, and the guide sleeve 210 is withdrawn from the needle tube 200;

[0100] Pull the two needles 200 out of the fascia 600 and remove the insertion end 110 from the opening of the fascia 600;

[0101] Using the needle tube 200 to pass through the fascia 600 at the opening, the suture 211 passing through the needle tube 200 also passes through the fascia 600 on both sides of the opening along with the guide sleeve 210, thereby suturing the fascia 600 on both sides of the opening. Then, the guide sleeve 210 is withdrawn from the needle tube 200. Taking advantage of the fact that the suture 211 can extend out of the release groove 112, the insertion end 110 is withdrawn from the opening of the fascia 600, so that the suture 211 is released from the release groove 112.

[0102] Finally, the suture 211 at the opening is knotted to achieve a good suturing effect on the fascia 600 on both sides of the opening.

[0103] Furthermore, before inserting the insertion end 110 of the central shaft 100 into the opening of the fascia 600, the recessed structure 120 is covered with a sleeve 300.

[0104] After inserting the insertion end 110 of the central shaft 100 into the opening of the fascia 600, the sleeve 300 is moved backward along the central shaft 100 so that the fascia 600 near the opening is placed in the corresponding recessed structure 120.

[0105] Without the sleeve 300 covering the recessed structure 120, the irregular shape of the recessed structure 120 could damage the fascia 600 at the opening when the insertion end 110 enters and exits the fascia 600. Therefore, the sleeve 300 is used to cover the recessed structure 120 during the insertion and exit of the insertion end 110 at the fascia 600 opening, effectively preventing damage to the fascia 600 near the opening due to the irregular shape of the recessed structure 120. This promotes wound healing at the fascia 600 opening.

[0106] See Figure 8 Therefore, the method of using the fascia stapler of the present invention includes:

[0107] Move the syringe 200 to the rear of the recessed structure 120;

[0108] The recessed structure 120 is covered with a sleeve 300;

[0109] Insert the insertion end 110 of the central shaft 100 into the opening of the fascia 600;

[0110] Move the sleeve 300 backward along the central axis 100;

[0111] Place the fascia 600 near the opening into the corresponding concave structure 120;

[0112] The two needles 200 are moved along the guide groove 130 and pass through the fascia 600 in the corresponding recessed structure 120 into the connecting hole 111;

[0113] One end of the guide sleeve 210 is inserted from one needle tube 200 through the connecting hole 111 into another needle tube 200, and the guide sleeve 210 extends out from the other needle tube 200, wherein the other end of the guide sleeve 210 is connected to the suture 211;

[0114] Only the guide sleeve 210 is removed from the needle tube 200, while the suture 211 remains in both needle tubes 200;

[0115] The two needles 200 are pulled out of the fascia 600;

[0116] The insertion tip 110 is withdrawn from the opening of the fascia 600;

[0117] Tie a knot at the suture line 211 at the opening.

[0118] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
