[0002] Suture needles are essential surgical tools and play a crucial role. In existing surgical suture systems, the thread and needle are often separate. Before suturing, the needle must be threaded. However, the needle holes of both the thread and the needle are very small, which wastes a significant amount of time. Furthermore, the needle must be removed after suturing, which is very inconvenient. Therefore, a suture thread with a needle has been proposed.

[0003] At present, needle-stitched sutures have been widely used in the ligation and suturing of various surgical tissues in clinical practice. During surgical treatment, it is inevitable to encounter unexpected situations such as bleeding at the surgical site. At this time, needle-stitched sutures are needed for rapid suturing to achieve rapid hemostasis and reduce bleeding.

[0004] Needle-threaded sutures are sutures that are threaded into a suture needle and crimped during production. Currently, conventional operations involve manual threading and simple crimping by a machine. This method results in sutures of varying lengths, low processing efficiency, and difficulty in guaranteeing crimping quality. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a needle suture assembly machine, which realizes automatic loading of suture and suture needle, automatic threading and pressing of suture and suture needle, as well as automatic detection and unloading after assembly. Figures 1-3As shown, it includes a cabinet 1, a suture feeding mechanism 2, a temporary storage bracket 3 and a discharge trough 4 installed side by side on the surface of the cabinet, a flipping and transferring mechanism 5 arranged between the suture feeding mechanism and the temporary storage bracket, and between the temporary storage bracket and the discharge trough, a threading mechanism 6 arranged at the front end of the temporary storage bracket, a pressing mechanism 7 arranged at the front end of the threading mechanism, and a suture needle feeding mechanism 8 arranged at the front end of the pressing mechanism, wherein the suture feeding mechanism realizes suture feeding, gluing and fixed-length cutting, the flipping and transferring mechanism realizes the transfer of the cut suture paper to the temporary storage bracket, and the end of the suture is inserted into the suture needle and pressed through the threading mechanism and the pressing mechanism, and another set of flipping and transferring mechanisms transfers the assembled suture with needle to the discharge trough.

[0027] The specific structure of the suture thread feeding mechanism is as follows Figure 4 As shown, it includes a feeding part 21, a gluing part 22, a clamping and shearing part 23, and a transverse wire pulling part 24, wherein the feeding part has a mounting frame 211, a spool 212 with a suture drum fixed on the upper end of the mounting frame, and a tensioning wheel adjustment assembly 213 fixed on the lower end of the mounting frame; the gluing part has an L-shaped mounting frame 221, two sets of threading brackets 222 fixed on the horizontal surface of the L-shaped mounting frame, and a glue coating tube 223 fixed on the vertical surface of the L-shaped mounting frame. The suture is led out from the spool and passes through the tensioning wheel adjustment assembly for tensioning adjustment, and then passes through the threading bracket and the lower end of the glue coating tube and is sent to the clamping and shearing part. In this way, the glue coating tube can coat the surface of the suture with glue during the pulling process, so that the suture becomes hard and is convenient for subsequent threading operations.

[0028] The clamping and shearing part includes a mounting bracket 231, pneumatic scissors 232, a shearing lifting cylinder 233 fixed at the end of the mounting bracket for controlling the lifting of the pneumatic scissors, and a first pneumatic clamp 234 fixed on the mounting bracket. The first pneumatic clamp and the pneumatic scissors are arranged in front and back, and the first pneumatic clamp clamps the glued suture thread.

[0029] The transverse moving wire pulling part includes a first linear module 241, a second pneumatic clamp 242 fixed on the slider of the first linear module, and a detection probe 243 fixed on the L-shaped mounting frame. The second pneumatic clamp moves to the first pneumatic clamp to clamp the end of the suture line. The first linear module drives the second pneumatic clamp to move horizontally to pull the wire. During the wire pulling process, the detection probe detects the wire pulling length. After reaching the required length, the first linear module stops working. At the same time, the first pneumatic clamp opens when pulling the wire, and clamps after stopping pulling the wire. At the same time, the pneumatic scissors descend to cut the suture line.

[0030] The flip transfer mechanism structure includes a rotating shaft 51, a driving motor 52 and two sets of clamping components 53. The two ends of the rotating shaft are fixed on the cabinet with bearing seats, and one end of the rotating shaft is assembled with the driving motor through a coupling. The driving motor controls the forward and reverse rotation of the rotating shaft. The two sets of clamping components are fixed at both ends of the rotating shaft. Its structure is as follows Figure 5As shown, it includes a connecting plate 531, a telescopic cylinder 532 fixed on the connecting plate, and a pneumatic clamp 533 fixed on the telescopic end of the telescopic cylinder. When flipping and transferring, the driving motor controls the rotating shaft to flip the clamping assembly to the side of the loading assembly, the telescopic cylinder extends and the pneumatic clamp clamps the suture thread, and then the driving motor controls the rotating shaft to rotate in the opposite direction so that the clamping assembly flips to the temporary storage bracket side, and the suture thread is placed on the temporary storage bracket.

[0031] The temporary storage bracket has a plurality of spaced apart frames 31, each frame surface is provided with a V-shaped bracket 32, and a partition 41 is provided in the middle of the feed trough to divide the feed trough into a good product trough and a defective product trough, which are respectively filled with qualified products and unqualified products.

[0032] The threading mechanism is arranged at the front end of the temporary storage bracket, and is used to clamp the end of the suture placed on the temporary storage bracket and move forward to thread the suture. The specific structure is as follows Figure 6 As shown, it includes a second linear module 61, a supporting seat 62 fixed on the slider of the second linear module, and a third pneumatic clamp 64 fixed to the front end surface of the supporting seat in conjunction with a lifting cylinder 63. A support plate 65 is provided on the upper surface of the supporting seat for supporting one end of the suture, and the third pneumatic clamp is controlled by the lifting cylinder to rise and clamp the end of the suture, and is moved forward by the second linear module to insert the end of the suture into the hole at the end of the suture needle.

[0033] The structure of the suture needle feeding mechanism is as follows Figure 7 As shown, it includes a vibrating loading tray 81, a manipulator 82, and a transverse clamping assembly 83. The transverse clamping assembly includes a third linear module 831, a fixed plate 832 and two groups of rotary pneumatic chucks 833. The fixed plate is fixed on the slider of the third linear module. The two groups of rotary pneumatic chucks are installed at both ends of the fixed plate in conjunction with the second telescopic cylinder 834. The rotary pneumatic chucks at both ends realize alternating loading. The vibrating loading tray vibrates and disperses the accumulated suture needles. The manipulator grabs the suture needles and sends them to the rotary pneumatic chuck for clamping. The clamped rotary pneumatic chuck rotates to make the suture needle horizontal. At the same time, the third linear module drives the rotary pneumatic chuck with the suture needle to move horizontally, so that the suture needle and the suture line on the threading mechanism are in a straight line. As the second linear module of the threading mechanism moves forward, the second telescopic cylinder drives the suture needle to move synchronously, so that the suture needle and the suture line move relative to each other to realize the threading operation.

[0034] The buckling mechanism performs a pressing operation on the threading point of the suture needle and the suture thread, and its structure is as follows: Figure 8As shown, it includes a fourth linear module 71, two groups of mounting seats 72 symmetrically arranged on the fourth linear module, and pressure plates 73 are installed on the opposite surfaces of the two groups of mounting seats. The two groups of mounting seats are relatively close to or relatively far away from each other on the linear module. When they are relatively close, the two pressure plates squeeze the assembly points of the suture thread and the suture needle to achieve buckling. When they are relatively far away, the suture thread is threaded forward or unthreaded backward after threading. In order to ensure the quality of buckling, an image detection head 74 is provided directly above the pressure plate to perform image quality detection on the connection after buckling.

[0035] The utility model discloses a needle-guided suture assembly machine, whose working principle is as follows: the suture needle is sent to the rotating pneumatic chuck for clamping by a mechanical claw, and is translated to the threading position; the suture feeding mechanism realizes the suture glue coating and fixed-length cutting; the cut suture is inserted into the suture needle by the threading mechanism, and the assembly position is buckled by the buckling mechanism, so that the suture and the suture needle form a whole; the buckled suture is tested for buckling quality by an image detection head, and can also be tested for pulling performance in conjunction with a tension detection device (not shown in the figure), and targeted cutting operations are performed according to the test results. The entire assembly machine has a high degree of automation, which can effectively achieve efficient and high-quality assembly, reduce manpower and cost investment, and improve overall efficiency.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
