[0034] Reference Figures 1 to 3 The present invention discloses a wound suturing device, comprising a shell 100, a knotting mechanism 200, a thread clamping mechanism 300, a suture needle 400 and a thread cutter 600. The shell 100 is provided with a support block 110, the support block 110 is provided with a vertical through hole, and the lower surface of the support block 110 is provided with a step 111; the knotting mechanism 200 comprises a connecting portion 210, an arc-shaped scraping arm 220 and an arc-shaped hook arm 230, the connecting portion 210 can be rotatably arranged in the through hole, the upper end of the scraping arm 220 is connected to the lower surface of the connecting portion 210, the upper end of the hook arm 230 is hinged to the upper end of the scraping arm 220 and is connected to a horizontally arranged slider 231, and the lower end of the hook arm 230 is provided with a hook portion; the thread clamping mechanism 300 can be swingably arranged on the shell 100, and the thread clamping mechanism 300 is used to move the middle section of the suture thread to the area between the hook portion and the lower end of the scraping arm 220; the suture needle 400 is arc-shaped The suture needle 400 is arranged in front of the knotting mechanism 200. The head of the suture needle 400 is provided with a threading hole for the front end end of the suture thread to pass through. The root of the suture needle 400 is connected to the housing 100 through the first rotating shaft 500. The suture needle 400 can rotate to pass the front end of the suture thread through the skin on both sides of the wound from front to back and move the front end of the suture thread between the hook portion and the lower end of the scraper arm 220; the connecting portion 210 rotates to make the slider 231 slide from the lower surface of the support block 110 to the lower surface of the step 111, the lower end of the hook arm 230 and the lower end of the connecting portion 210 are opened, the slider 231 slides from the lower surface of the step 111 to the lower surface of the support block 110, the hook portion is close to the lower end of the scraper arm 220 and hooks the front end of the suture thread after passing through the skin on both sides of the wound and the middle section of the suture thread; the thread cutter 600 is arranged on the housing 100, and the thread cutter 600 is used to cut off the rear end of the suture thread.

[0035] When the connecting part 210 carries the scraper arm 220 and the hook arm 230 to rotate, since the upper end of the hook arm 230 is hinged with the upper end of the scraper arm 220, the upper end of the hook arm 230 is connected with a horizontally arranged slider 231, the connection point between the upper end of the hook arm 230 and the upper end of the scraper arm 220 is a fulcrum, the hook arm 230 and the slider 231 are a lever structure, the slider 231 is against the lower surface of the support block 110, and the hook portion is close to the lower end of the scraper arm 220, so that the hook portion and the lower end of the scraper arm 220 are in a closed state, and the hook portion can hook the middle section of the suture and the front section of the suture. As the connecting part 210 continues to rotate, the slider 231 slides on the lower surface of the support block 110 and is converted to slide on the lower surface of the step 111. At this time, the lower end of the hook portion and the scraper arm 220 is in an open state, so that the middle section of the suture and the front section of the suture enter the area between the hook portion and the lower end of the scraper arm 220.

[0036] The front end of the suture thread is passed through the threading hole in advance. The suture needle 400 rotates around the central axis of the first rotating shaft 500, that is, the suture needle 400 rotates around the left and right axes, and the suture needle 400 passes the front end of the suture thread through the skin on the front and back sides of the wound, and moves the front end of the suture thread to between the hook and the lower end of the scraper arm 220; then the suture needle 400 rotates in the opposite direction around the left and right axes, that is, the suture needle 400 is reset. During this process, the front end of the suture thread remains stationary, and the middle section of the suture thread is on the clamping mechanism 300. After the suture needle 400 is reset, it will avoid interference with the clamping mechanism 300; then the clamping mechanism 300 moves the middle section of the suture thread to the area between the hook and the lower end of the scraper arm 220, and at this time, the front section of the suture thread and the middle section of the suture thread are in the same position.

[0037] Then the connecting part 210 carries the scraper arm 220 and the hook arm 230 to rotate on the support block 110. Since the scraper arm 220 and the hook arm 230 are both arc-shaped, the front section and part of the middle section of the suture are wrapped around the scraper arm 220 and the hook arm 230. The lower ends of the hook and the scraper arm 220 complete the transition between the open and closed states. When the hook and the scraper arm 220 are closed, they hook the front section and another part of the middle section of the suture. As the hook and the scraper arm 220 continue to rotate, the front section and part of the middle section of the suture fall off the hook and are wrapped around another part of the front section and the middle section of the suture. The front section and the middle section of the suture are detached from the hook, completing the knotting of the front section and the middle section of the suture, and the wire cutter 600 cuts the rear end of the suture.

[0038] The wound suturing device replaces the manually operated suturing needle, effectively improving the speed of wound suturing, reducing the number of steps, reducing the suturing technical requirements for medical personnel, and saving time and effort.

[0039] The wound suturing device also includes an unwinding device, which is used to release the suture thread. The unwinding device can be connected to the housing 100 or fixed in an independent manner.

[0040] Reference Figure 3 It is conceivable that the support block 110 is annular. The connecting portion 210 is vertically columnar, and the connecting portion 210 can be connected to the support block 110 by using a first bearing.

[0041] In some of the embodiments, the wound suturing device also includes a first rotary drive mechanism 120 disposed in the shell 100, and the output end of the first rotary drive mechanism 120 is transmission-connected to the upper end of the connecting part 210 through two mutually meshing first gears 121. The first rotary drive mechanism 120 drives the connecting part 210 to rotate around the upper and lower axes on the support block 110 through two mutually meshing first gears 121, and the connecting part 210 drives the scraping arm 220 and the hook arm 230 to rotate.

[0042] Reference Figure 3 In some embodiments, the length direction of the output end of the first rotary drive mechanism 120 is the left-right direction, and the first gear 121 is a bevel gear, one bevel gear is provided at the output end of the first rotary drive mechanism 120, and the other bevel gear is provided at the upper end of the connecting portion 210, and the two bevel gears are meshed with each other. The provision of the two bevel gears realizes right-angle transmission, so that the first rotary drive mechanism 120 can be provided horizontally, that is, the first rotary drive mechanism 120 is located next to the knotting mechanism 200, which can reduce the first rotary drive mechanism 120 from blocking the operator's line of sight, so that the operator can more easily observe the knotting mechanism 200.

[0043] In some of the embodiments, a second rotating shaft 130 is provided on the shell 100, and the length direction of the second rotating shaft 130 is the front-to-back direction. The output end of the first rotation drive mechanism 120 is transmission connected to one end of the second rotating shaft 130 through two mutually meshing second gears 122, and the first rotation drive mechanism 120 drives the second rotating shaft 130 to rotate through the two mutually meshing second gears 122.

[0044] Reference Figure 2 and Figure 3 The thread cutter 600 includes a sliding portion 610 and a hook-shaped knife portion 620. The sliding portion 610 is arranged on the shell 100 and can slide along the left and right directions. The other end of the second rotating shaft 130 is connected to the sliding portion 610 through a transmission mechanism to drive the sliding portion 610 to slide along the left and right directions. The knife portion 620 moves along the left and right directions to cut off the rear end of the suture thread.

[0045] The second rotating shaft 130 drives the sliding part 610 and the knife part 620 to slide along the left and right directions on the housing 100 through the transmission mechanism, so as to realize the conversion of the rotational motion into the linear reciprocating motion. Initially, the second rotating shaft 130 drives the sliding part 610 and the knife part 620 to move to the left or right, avoiding the interference of the sliding part 610 and the knife part 620 with the clamping mechanism 300, so that the clamping mechanism 300 can smoothly move the middle section of the suture to the area between the hook part and the lower end of the scraper arm 220, and the rear end of the suture is on the motion track of the knife part 620. When the second rotating shaft 130 drives the sliding part 610 and the knife part 620 to move to the right or left, that is, the sliding part 610 and the knife part 620 are reset, the knife part 620 can cut off the rear end of the suture.

[0046] Reference Figure 3 In some embodiments, the second gear 122 is a helical gear, one helical gear is fixedly mounted on the output end of the first rotation drive mechanism 120, and the other helical gear is fixedly mounted on one end of the second rotating shaft 130. The two helical gears enable the second rotating shaft 130 and the output end of the first rotation drive mechanism 120 to be arranged perpendicular to each other.

[0047] The transmission mechanism includes a ruler structure 611 arranged on the sliding part 610 and a spur gear 131 arranged on the other end of the second rotating shaft 130. The ruler structure 611 and the spur gear 131 are meshed with each other. When the second rotating shaft 130 drives the spur gear 131 to rotate, the spur gear 131 drives the ruler structure 611 to move in the left and right directions.

[0048] It can be understood that the knotting mechanism 200 is disposed on the left side of the shell 100 , the first rotary drive mechanism 120 is disposed in the shell 100 , and the output end of the first rotary drive mechanism 120 faces left and extends to the left side of the shell 100 .

[0049] The thread cutter 600 is disposed in front of the knotting mechanism 200. The second shaft 130 is disposed on the left side of the housing 100 through a second bearing. A second gear 122 is fixedly sleeved on the rear end of the second shaft 130, and a spur gear 131 is fixedly sleeved on the front end of the second shaft 130.

[0050] A portion of the blade of the knife portion 620 faces right, and another portion of the blade of the knife portion 620 faces downward. When the knife portion 620 moves to the left, the middle section of the suture can move smoothly between the hook portion and the lower end of the scraper arm 220. When the knife portion 620 moves to the right, the knife portion 620 can hook the rear end of the suture and cut or sever the rear end of the suture.

[0051] Reference Figure 2 and Figure 4In some embodiments, the wound suturing device further includes a second rotary drive mechanism 140 disposed in the shell 100, the output end of the second rotary drive mechanism 140 is connected to an eccentric shaft 141, the length direction of the eccentric shaft 141 is the front-to-back direction, and a jacket 142 is rotatably mounted on the eccentric shaft 141. The second rotary drive mechanism 140 drives the eccentric shaft 141 and the jacket 142 to rotate around the front-to-back axis.

[0052] A first guide sleeve 143 is provided on the outer circular surface of the sleeve 142, and the length direction of the first guide sleeve 143 is the left-right direction. A first guide column is inserted into the first guide sleeve 143, and the first rotating shaft 500 is rotatably provided on the shell 100, and the length direction of the first rotating shaft 500 is the left-right direction. One end of the first rotating shaft 500 is connected to a swing arm 510, and the free end of the swing arm 510 is connected to the first guide column, and the other end of the first rotating shaft 500 is connected to the root of the suture needle 400.

[0053] The sleeve 142 can rotate on the eccentric shaft 141. When the sleeve 142 rotates around the front and rear axes, the posture of the sleeve 142 remains unchanged, that is, the length direction of the first guide sleeve 143 is always in the left and right direction. Part of the structure of the first guide column can rotate and slide in the first guide sleeve 143, thereby driving the swing arm 510 to swing, and the swing arm 510 drives the first rotating shaft 500 to rotate, thereby driving the suture needle 400 to rotate around the left and right axes.

[0054] It can be imagined that the suture needle 400 is in an arc shape. After the suture needle 400 pierces the skin on the front and back sides of the wound, the suture needle 400 can return to the initial position along the original path, thereby improving the comfort of the puncture of the suture needle 400.

[0055] Reference Figure 2 and Figure 4 In some embodiments, the wound suturing device further includes a second rotary drive mechanism 140 disposed in the shell 100, the output end of the second rotary drive mechanism 140 is connected to an eccentric shaft 141, the length direction of the eccentric shaft 141 is the front-to-back direction, a disc 144 is fixedly sleeved on the eccentric shaft 141, and the second rotary drive mechanism 140 drives the eccentric shaft 141 and the disc 144 to rotate around the front-to-back axis.

[0056] A side plate 145 is provided on the outer edge of the disc 144. The side plate 145 forms an angle with the front-rear direction. One end of the side plate 145 is close to the front of the eccentric shaft 141. A second guide column 146 is provided at one end of the side plate 145. The axis of the second guide column 146 intersects with the axis of the eccentric shaft 141. A second guide sleeve 147 is sleeved on the second guide column 146. The outer wall of the second guide sleeve 147 is connected to a third guide sleeve 148. The third guide sleeve 148 is provided with a The third guide column 149, the thread clamping mechanism 300 includes a suspension rod 310, a rocker arm 320 and a U-shaped clamp 330 arranged on one end of the rocker arm 320, the other end of the rocker arm 320 is connected to the third guide column 149, the upper end of the suspension rod 310 is hung on the shell 100, and one end of the rocker arm 320 is hung on the lower end of the suspension rod 310, and the U-shaped clamp 330 is used to move the middle section of the suture thread to the area between the hook and the lower end of the scraper arm 220.

[0057] When the second rotary drive mechanism 140 drives the eccentric shaft 141 and the disc 144 to rotate around the front and rear axes, the rocker arm 320 performs a movement similar to a paddle, and the rocker arm 320 drives the U-shaped clamp 330, so that the U-shaped clamp 330 can move the middle section of the suture thread to the area between the hook and the lower end of the scraper arm 220.

[0058] It can be understood that the clamping area of ​​the U-shaped clamp 330 intersects with the movement trajectory of the suture needle 400. When the suture needle 400 is reset, the middle section of the suture thread is just in the clamping area of ​​the U-shaped clamp 330, so that the U-shaped clamp 330 can clamp or hook the middle section of the suture thread, thereby driving the middle section of the suture thread to move to the area between the hook portion and the lower end of the scraper arm 220.

[0059] Reference Figure 2 In some embodiments, a U-shaped rod is provided at the other end of the rocker arm 320, and the two ends of the U-shaped rod are respectively connected to the two ends of the third guide column 149, and the third guide sleeve 148 is located between the two ends of the U-shaped rod, which can prevent the third guide column 149 from detaching from the third guide sleeve 148. The third guide column 149 rotates under the limit of the third guide sleeve 148.

[0060] In some of the embodiments, a first connecting hole is provided at the upper end of the suspension rod 310, and the axial direction of the first connecting hole is the front-to-back direction. A fastener 700 is movably inserted into the first connecting hole, and the fastener 700 is connected to the shell 100, so that the upper end of the suspension rod 310 is suspended on the shell 100. A universal ball is provided at the lower end of the suspension rod 310, and the universal ball is provided with a second connecting hole. One end of the rocker arm 320 is inserted into the second connecting hole.
