This not only greatly improves the safety of the operation and reduces the risk of the operation, but also optimizes the surgical process, improves the surgical efficiency, reduces the pain of the patient during the operation, provides a strong guarantee for the smooth development of the operation and the recovery of the patient.
[0070] One end of the movable jaw 210 cooperates with one end of the pointed jaw 110 to form a jaw head, and the other end is rotatably connected with one end of the connecting rod 310 and the pointed tube 100; the pointed jaw protrusion 111 corresponds to the skylight through hole 211; the jaw head is made of high-strength and high-hardness metal material, and will not be broken, thus effectively improving the mechanical strength and service life, ensuring that the jaw head will not be broken and left in the cavity, and greatly reducing the risk of medical accidents; the pointed jaw connecting groove 114 is arranged outside the movable jaw lug 212, the two first pointed jaw connecting holes 115 are riveted with the two first movable jaw connecting holes 213 through a first pin 810, a gap is left during riveting, the pointed jaw 110 is rotatably connected with the movable jaw 210, and a rotating structure is formed; the two second pointed jaw connecting holes 116 are connected with the arc-shaped limiting hole 413 through a second pin 820, the pointed jaw 110 is slidably connected with the limiting plate 410, the second pin 820 can slide along the arc of the arc-shaped limiting hole 413, and the opening angle of the jaw head is limited; the two second movable jaw connecting holes 214 are pinned with the first limiting plate connecting hole 411 through a third pin 830, and the second limiting plate connecting hole 412 is pinned with the two first connecting rod connecting holes 312 through a fourth pin, so that the other end of the movable jaw 210 is rotatably connected with one end of the connecting rod 310 through the limiting plate 410, a driving structure is formed, and the jaw head is driven to open and close; the shear pin is arranged in the second connecting rod connecting hole; the other end of the connecting rod 310 is rotatably connected with one end of the finger operating rod 520 through the shear pin, a driving structure is formed, and the connecting rod 310 is driven to slide in the connecting tube 120, so that the jaw head is opened or closed.
[0071] The working process of the novel medical operation wire passing forceps provided by the utility model is as follows:
[0072] The suture needle 710 is inserted into the pointed tube 100, the end groove 712 of the suture needle 710 is connected with one end of the palm operating rod 530 through pin cooperation, the palm operating rod 530 is pressed to move towards the thumb operating rod 510, the suture needle 710 is taken out from the U-shaped gap of the pointed jaw protrusion 111, the suture wire is hung in the needle groove 711 of the suture needle 710, the palm operating rod 530 is loosened, the first reset spring 910 is activated to reset the palm operating rod 530, and the suture needle 710 drives the suture wire to retreat into the needle container tube, and the wire hanging operation is completed.
[0073] Lifting the pressing structure 611 and pressing the finger operating lever 520 towards the thumb operating lever 510 drives the clamp head to close, grasping the soft tissue. At this time, the limiting buckle 612 separates from the limiting post 511, the hook spring 930 extends, and the hook 610 engages with the ratchet 620 for self-locking, ensuring the operating handle is locked and keeping the clamp head closed. Pressing the palm operating lever 530 towards the thumb operating lever 510 causes the suture needle 710 to drive the suture thread through the U-shaped notch of the tip clamp protrusion 111, passing through one side of the soft tissue and opening the movable window 220 to complete the threading operation. Releasing the palm operating lever 530 activates the first return spring 910, returning the palm operating lever 530 to its original position. When the suture needle 710 retracts into the needle holder, the movable window 220 closes with the movable jaw 210 under the action of the torsion spring, clamping the suture and leaving a portion of the suture on the other side of the soft tissue. Pressing down the pressing structure 611 causes the limiting buckle 612 to engage with the limiting post 511, compressing the hook spring 930 and separating the hook 610 from the ratchet 620. This disengages the hook 610 from the ratchet 620, releasing the self-locking state of the operating handle. The second return spring 920 then returns the finger operating lever 520 to its original position, allowing the clamp head to loosen the soft tissue. With the movable window 220 clamping the suture, the threading clamp is removed, and the suture is pulled out, completing the threading and suture removal operation.
[0074] Pull the clamped suture upwards to separate the movable window 220 from the movable jaws 210, allowing the suture to move freely. With the movable window 220 separated from the movable jaws 210, move the suture into the movable window suture release groove 223. Since the suture exerts no upward pulling force on the head of the movable window 220, the movable window 220 will close again with the movable jaws 210 under the action of the torsion spring 230, and the suture will be in the movable window suture release groove 223. Pull the suture downwards to remove it from the movable window suture release groove 223, completing the suture release operation.
[0075] This novel medical surgical suture forceps integrates tissue grasping, suture threading, and suture removal into one unit, greatly simplifying the surgical procedure, shortening surgical time, avoiding surgical errors, and improving surgical safety and efficiency. The self-locking handle design allows the handle to lock automatically when gripped for extended periods, reducing the force required by the surgeon, facilitating extension and retraction, alleviating surgical fatigue, and preventing the handle from falling off. The handle limiting design effectively controls the suture needle's stroke through a limiting linkage, preventing suture jamming, detachment, and damage to other soft tissues during needle threading, ensuring surgical safety. The forceps head is made of high-strength, high-hardness metal material, improving mechanical strength and service life, and reducing the risk of medical accidents. The notch design on the right side of the movable window maximizes the strength of the forceps jaws while facilitating suture removal, avoiding the previous situation where forcibly pulling the suture at the movable window head could damage the suture due to the teeth, or requiring the complex operation of manually prying open the movable window for suture removal. This effectively improves surgical efficiency and protects the integrity of the suture. Furthermore, the ergonomic handle design, based on the small to medium hand size of Chinese people, reduces surgeon fatigue during prolonged surgeries and enhances the user experience.
