Description

Technical Field

[0001] This invention belongs to the field of medical supplies technology, specifically a portable wound suture device. Background Technology

[0002] The portable wound suture device is a sophisticated and quick-operating modern emergency medical instrument designed to replace traditional needle and thread sutures, particularly suitable for pre-hospital emergency care, battlefield rescue, and outdoor emergency medical scenarios. Driven by a mechanical structure, it can precisely implant specially designed medical titanium staples or high-strength bio-adhesive tape into both sides of the wound within seconds, much like a medical stapler, achieving rapid closure and reliable alignment of the skin wound. This device significantly shortens wound treatment time, greatly reduces the risk of infection due to wound exposure, and alleviates patient pain and fear.

[0003] Patent document WO2012167745A1 discloses a skin wound suture device that can promote skin wound healing, including suture structures disposed on both sides of the skin wound, a retractable suture force adjustment device disposed between the suture structures on both sides of the skin wound, and a force measuring device for measuring the magnitude of the suture force disposed between the suture structures on both sides of the skin wound. One end of the force measuring device is disposed on the suture structure on one side of the skin wound, and the other end of the force measuring device is disposed on the suture structure on the other side of the skin wound.

[0004] Existing skin wound closure devices have certain shortcomings in use. The aforementioned skin wound closure devices are large in size and complex to operate, requiring the cooperation of professional medical personnel. In emergency situations, conventional skin wound closure devices are not suitable for outdoor emergency scenarios, and indiscriminate use may lead to secondary damage to the incision. Secondly, conventional skin wound closure devices do not have an incision sealing structure. When the skin wound closure device is used to fix the incision directly, it is to suture and fix the skin incision in an open state. The fixed skin incision position is not tightly closed, which affects the later recovery of the incision. Summary of the Invention

[0005] This invention provides a portable wound suture device that solves the problems of traditional skin wound suture devices being unsuitable for outdoor emergency scenarios, causing secondary damage to the wound if used haphazardly, and failing to tightly close the wound after fixation when directly using the skin wound suture device, thus affecting the later recovery of the wound. A portable wound suturing device includes an outer shell, a presser, and a staple cartridge. The presser is elastically mounted on its inner side. A staple pusher plate is movably mounted on the lower part of the presser. The staple pusher plate and the presser are driven by a slanted panel. A staple cartridge for loading titanium staples is provided on the inner side of the outer shell at the lower part of the presser. An anvil is fixedly mounted on the lower end of the outer shell below the staple pusher plate. A presser is fixedly mounted on the outer surface of the lower end of the outer shell on one side of the anvil.

[0006] As a further technical solution of the present invention, two sets of transverse springs are provided on one side of the presser. The outer shell and the presser are elastically connected by the transverse springs. The inclined plate is located at the lower part of one side of the presser. During operation, by pressing the presser, the presser drives the pusher plate to move down using the inclined plate. The pusher plate pushes the titanium nail, thereby shooting the titanium nail downward. The transverse springs play an elastic restoring role for the presser.

[0007] As a further technical solution of the present invention, a fixing frame is fixedly installed on the upper outer surface of the pusher plate, and a roller is fixedly installed on the inner side of the fixing frame. The setting of the roller can reduce the friction between the inclined panel and the pusher plate. By pushing the roller with the inclined panel, the roller rolls on the surface of the inclined panel, thereby converting the lateral movement of the presser into the vertical movement of the pusher plate.

[0008] As a further technical solution of the present invention, the pusher plate and the outer shell are elastically connected by a vertical spring. The vertical spring is located on both sides of the pusher plate. The inner part of the outer shell is provided with a sliding groove for use with the pusher plate. During operation, the user presses the presser, which causes the presser to move the inclined plate at its lower part. One side of the inclined plate adopts an inclined structure design. When the inclined plate contacts the roller, the inclined structure of the inclined plate pushes the roller down, while reducing the friction of the inclined plate surface. When the roller moves down, the fixed frame drives the pusher plate to move down, so that the pusher plate shoots the titanium nail in the nail cartridge downward, so that the titanium nail passes through the guide sleeve of the anvil. When the titanium nail is shot out, the guide sleeve causes the two ends of the titanium nail to bend inward, so that the two ends of the titanium nail pass through both sides of the skin incision. With the bending deformation of the two ends of the titanium nail, the incision is closed and fixed, and the titanium nail is fixed on the incision.

[0009] As a further technical solution of the present invention, a slot is provided on the upper outer surface of the presser, and a safety buckle is fixedly provided on the upper end of the outer shell to cooperate with the slot. During operation, the safety buckle is used to fix the slot, so that the presser is in a locked and fixed state, preventing the presser from being pressed and avoiding accidental ejection of titanium nails. Secondly, when the presser is released, the presser is reset by the horizontal spring, and at the same time, the vertical spring is reset to the pusher plate.

[0010] As a further technical solution of the present invention, a guide sleeve is fixedly installed on the inner side of the anvil. The inner side of the guide sleeve is provided with a sloping groove. When the titanium nail passes through the guide sleeve, the two ends of the titanium nail are bent and deformed by the setting of the sloping groove. When the titanium nail completely passes through the guide sleeve, the two ends of the titanium nail are bent inward by ninety degrees, thereby completing the locking and fixing of the skin tissue.

[0011] As a further technical solution of the present invention, the inner side of the titanium nail is provided with two sets of bending grooves, both sets of bending grooves are located at the same height of the titanium nail. By using the setting of bending grooves, the nail foot structure of the titanium nail is more easily bent, allowing the nail ejector plate to easily eject the titanium nail and allowing the nail foot of the titanium nail to be bent and fixed. When the presser is pressed to perform the nail injection operation, the use of the presser is more labor-saving, allowing the titanium nail to complete the fixation operation of skin tissue more effortlessly.

[0012] As a further technical solution of the present invention, two sets of guide blocks are fixedly installed on the inner side of the presser. The two sets of guide blocks are arranged in a mirror symmetrical manner. By using the guide blocks, the incision position can be assisted to close when the suturer performs the incision suturing operation, thereby improving the fixation effect of the titanium nail.

[0013] As a further technical solution of the present invention, one side of the outer surface of the guide block is provided with a beveled part and a flat part, and the flat part is located at one end of the beveled part. During operation, the presser at the lower end of the outer shell is moved to fit the skin incision. Using the beveled parts of the two sets of guide blocks, the presser gradually tightens the skin on both sides of the incision as it moves. When the skin at the incision moves to the flat part, the skin on both sides of the incision closes with each other. This, together with the titanium nail, completes the fixation operation of the skin at the incision, avoiding the phenomenon of the incision splitting after the titanium nail is fixed, and improving its suturing effect.

[0014] As a further technical solution of the present invention, an elastic top plate is elastically installed on the inner side of the nail cartridge, and the titanium nail is installed on one side of the elastic top plate. One end of the nail cartridge is provided with a through hole for use with a pusher plate. During operation, the elastic top plate is used to elastically push the titanium nail to move. When a titanium nail is fired, the titanium nail behind it moves forward to replenish it. The design of the through hole structure allows the pusher plate to pass through the nail cartridge and fire the titanium nail downwards.

[0015] The beneficial effects of the present invention are as follows: The present invention uses a push plate and anvil to drive the titanium nails in the portable wound suture device by a press-type push structure, which reduces the size of the suture device itself, reduces its operation difficulty, and makes the suture device more suitable for emergency situations, and can quickly complete the suturing operation of the wound. In daily operation, the titanium nails are installed inside the nail cartridge, which is then inserted into the outer casing. The anvil is aligned with the skin incision and moved along the incision. Simultaneously, the user presses the pressure device, causing it to move the lower inclined plate. One side of the inclined plate features a beveled design. When the inclined plate contacts the roller, its beveled structure pushes the roller downwards, reducing friction on the plate surface. As the roller moves downwards, the fixing bracket drives the pusher plate downwards, ejecting the titanium nails from the cartridge downwards. As the titanium nail is ejected through the guide sleeve of the anvil, the guide sleeve causes the two ends of the titanium nail to bend inward, allowing the two ends of the titanium nail to pass through both sides of the skin incision. The bending deformation of the titanium nail ends closes and fixes the incision, securing the titanium nail to the incision. Secondly, the setting of the bending groove makes the nail foot structure easier to bend, allowing the pusher plate to easily eject the titanium nail and complete the bending and fixation of the titanium nail foot. When the presser is pressed to perform the nail injection operation, the use of the presser is more labor-saving, allowing the titanium nail to complete the fixation operation of the skin tissue more effortlessly. By incorporating a compression device, this portable wound suture device features an incision-assisted compression structure, enabling suturing and fixation to be completed even when the incision is closed, thus preventing the incision from reopening after suturing and improving the effectiveness of the suture device. During operation, the presser at the lower end of the outer shell is moved to fit the skin incision. Using the inclined surfaces of the two sets of guide blocks, the presser gradually tightens the skin on both sides of the incision as it moves. When the skin at the incision moves to the flat surface, the skin on both sides of the incision closes together. This, combined with the titanium staples, completes the fixation of the skin at the incision, preventing the incision from splitting after fixation and improving the suturing effect.

Detailed Implementation

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1-4 As shown, a portable wound suture device includes an outer shell 1, a presser 2, and a staple cartridge 5. The presser 2 is elastically installed inside the presser 2. A staple pusher plate 12 is movably installed at the lower part of the presser 2. The staple pusher plate 12 and the presser 2 are driven by a slanted panel 13. The staple cartridge 5 for loading titanium staples 6 is provided on the inner side of the outer shell 1 at the lower part of the presser 2. An anvil 4 is fixedly installed at the lower end of the outer shell 1 below the staple pusher plate 12. A presser 3 is fixedly installed on the outer surface of the lower end of the outer shell 1 on one side of the anvil 4.

[0020] Two sets of transverse springs 10 are provided on one side of the presser 2. The outer shell 1 and the presser 2 are elastically connected by the transverse springs 10. The inclined plate 13 is located at the lower part of one side of the presser 2. During operation, by pressing the presser 2, the presser 2 drives the pusher plate 12 to move down by using the inclined plate 13. The pusher plate 12 pushes the titanium nail 6, thereby shooting the titanium nail 6 downward. The transverse springs 10 play an elastic restoring role for the presser 2.

[0021] A fixing frame 15 is fixedly installed on the upper outer surface of the pusher plate 12, and a roller 14 is fixedly installed on the inner side of the fixing frame 15. The setting of the roller 14 can reduce the friction between the inclined panel 13 and the pusher plate 12. By pushing the roller 14 with the inclined panel 13, the roller 14 rolls on the surface of the inclined panel 13, thereby converting the lateral movement of the presser 2 into the vertical movement of the pusher plate 12.

[0022] The pusher plate 12 and the outer shell 1 are elastically connected by a vertical spring 11. The vertical spring 11 is located on both sides of the pusher plate 12. The inner part of the outer shell 1 is provided with a sliding groove for use with the pusher plate 12. During operation, the user presses the presser 2, which causes the presser 2 to move the inclined plate 13 at its lower part. One side of the inclined plate 13 adopts an inclined structure design. When the inclined plate 13 contacts the roller 14, the inclined structure of the inclined plate 13 pushes the roller 14 down, while reducing the friction of the inclined plate 13 surface. When the roller 14 moves down, the fixing frame 15 drives the pusher plate 12 to move down, so that the pusher plate 12 ejects the titanium nail 6 in the nail cartridge 5 downward, so that the titanium nail 6 passes through the guide sleeve 16 of the anvil 4. When the titanium nail 6 is ejected, the guide sleeve 16 causes the two ends of the titanium nail 6 to bend inward, so that the two ends of the titanium nail 6 pass through the two sides of the skin incision. With the bending deformation of the two ends of the titanium nail 6, the incision is closed and fixed, and the titanium nail 6 is fixed on the incision.

[0023] The upper outer surface of the presser 2 is provided with a slot 9, and the upper end of the outer shell 1 is fixedly provided with a safety buckle 8 that works with the slot 9. During operation, the safety buckle 8 is used to fix the slot 9, so that the presser 2 is locked in a fixed state, preventing the presser 2 from being pressed and avoiding the titanium nail 6 from being accidentally ejected. Then, when the presser 2 is released, the horizontal spring 10 is used to reset the presser 2, and at the same time, the vertical spring 11 is used to reset the pusher plate 12 upward.

[0024] A guide sleeve 16 is fixedly installed on the inner side of the anvil 4. The inner side of the guide sleeve 16 is provided with a sloping groove 17. When the titanium nail 6 passes through the guide sleeve 16, the sloping groove 17 causes the two ends of the titanium nail 6 to bend and deform. When the titanium nail 6 completely passes through the guide sleeve 16, the two ends of the titanium nail 6 bend inward by ninety degrees, thus completing the locking and fixing of the skin tissue.

[0025] The inner side of the titanium nail 6 is provided with two sets of bending grooves 18. Both sets of bending grooves 18 are located at the same height of the titanium nail 6. The setting of the bending grooves 18 makes the nail foot structure of the titanium nail 6 easier to bend, allowing the nail pusher plate 12 to easily eject the titanium nail 6 and complete the bending and fixing of the nail foot of the titanium nail 6. When the presser 2 is pressed to perform the nail injection operation, the use of the presser 2 is more labor-saving, allowing the titanium nail 6 to complete the fixation operation of the skin tissue more effortlessly.

[0026] Two sets of guide blocks 19 are fixedly installed on the inner side of the presser 3. The two sets of guide blocks 19 are arranged in a mirror symmetrical manner. By using the guide blocks 19, the incision position can be assisted to close when the suturer is performing incision suturing, thereby improving the fixation effect of the titanium nail 6.

[0027] One outer surface of the guide block 19 is provided with a beveled part 20 and a flat part 21. The flat part 21 is located at one end of the beveled part 20. During operation, the presser 3 at the lower end of the outer shell 1 is moved to fit the skin incision. Using the beveled parts 20 of the two sets of guide blocks 19, the presser 3 gradually tightens the skin on both sides of the incision as it moves. When the skin of the incision moves to the flat part 21, the skin on both sides of the incision closes with each other. The titanium nail 6 is used to complete the fixation of the skin at the incision, avoiding the splitting of the incision after the titanium nail 6 is fixed, and improving the suturing effect.

[0028] An elastic top plate 7 is elastically installed on the inner side of the nail cartridge 5. Titanium nails 6 are installed on one side of the elastic top plate 7. One end of the nail cartridge 5 is provided with a through hole for use with the pusher plate 12. During operation, the elastic top plate 7 is used to elastically push the titanium nails 6 to move. When a titanium nail 6 is fired, the titanium nails 6 behind it are moved forward to replenish it. The design of the through hole structure allows the pusher plate 12 to pass through the nail cartridge 5 and fire the titanium nails 6 downwards.

[0029] A portable wound suture device is disclosed. In use, titanium nails 6 are installed inside a nail cartridge 5, which is then inserted into the outer casing 1. The anvil 4 is aligned with the skin incision and moved along the incision. Simultaneously, the user presses a pressure device 2, which moves a lower inclined plate 13. One side of the inclined plate 13 has a beveled design. When the inclined plate 13 contacts a roller 14, the beveled structure pushes the roller 14 downwards, reducing friction on the surface of the inclined plate 13. As the roller 14 moves downwards, a fixing frame 15 drives a nail pusher plate 12 downwards, causing the nail pusher plate 12 to push the titanium nails from the nail cartridge 5. The nail 6 is ejected downwards, allowing it to pass through the guide sleeve 16 of the anvil 4. As the nail 6 is ejected, the guide sleeve 16 causes both ends of the nail 6 to bend inwards, allowing them to pass through both sides of the skin incision. The bending deformation of the ends of the nail 6 closes and fixes the incision, securing the nail 6 to the incision. Furthermore, the bending groove 18 makes the nail foot structure of the nail 6 easier to bend, allowing the pusher plate 12 to easily eject the nail 6 and bend and fix its feet. When the presser 2 is pressed to perform the nail ejection operation, the presser 2 is used more effortlessly, allowing the nail 6 to complete the fixation operation on the skin tissue more effortlessly. The presser 3 at the lower end of the outer shell 1 is moved to fit the skin incision. Using the inclined surfaces 20 of the two sets of guide blocks 19, the presser 3 gradually tightens the skin on both sides of the incision as it moves. When the skin at the incision moves to the flat surface 21, the skin on both sides of the incision closes together. This, together with the titanium nail 6, completes the fixation of the skin at the incision, preventing the incision from splitting after the titanium nail 6 is fixed, and improving the suturing effect.
