Description

Technical Field

[0001] The invention belongs to the technical field of medical instruments, and in particular relates to a novel medical surgical wire passing forceps. Background Art

[0002] Arthroscopic surgery is different from conventional surgery. Arthroscopic surgery is to perform surgery on lesions or damaged structures in the joint cavity under arthroscopy. This surgery has high technical requirements, is difficult to operate, and has high standards for surgical operations. Tendon injuries are common in the field of sports medicine. With the continuous development of orthopedic sports medicine, the number of tendon repair surgeries has shown an increasing trend year by year. In the traditional tendon repair process, multiple instruments need to be used for coordinated operation. First, tissue graspers are used to grasp the tissue, and then the wire is threaded through the grasped tissue using a wire threader. After that, the suture is grasped by the wire grasper for suturing. This multi-instrument coordination mode has many disadvantages. The operation process is extremely cumbersome, which seriously affects the efficiency of the operation. In addition, frequent switching of instruments during the operation can easily cause confusion of instruments and bring potential risks to the operation. At the same time, doctors need to hold the instruments continuously during long-term surgical operations, which is not convenient for operation and is easy to slip out of the hands, resulting in loosening of the surgical site, which is not conducive to the smooth progress of the operation.

This not only greatly improves the safety of the operation and reduces the risk of the operation, but also optimizes the operation process, improves the efficiency of the operation, reduces the pain of the patient during the operation, and provides a strong guarantee for the smooth operation and the recovery of the patient.

[0070] One end of the movable jaw 210 cooperates with one end of the tip jaw 110 to form a clamp head, and the other end is rotatably connected to one end of the connecting rod 310 and the tip tube 100; the tip jaw protrusion 111 corresponds to the skylight through hole 211; the clamp head is made of high-strength and high-hardness metal material, which will not break, effectively improving the mechanical strength and service life, ensuring that the clamp head will not break and remain in the cavity, greatly reducing the risk of medical accidents; the tip jaw connecting groove 114 is sleeved on the outside of the movable jaw lifting ear 212, and the two first tip jaw connecting holes 115 and the two first movable jaw connecting holes 213 are riveted by the first pin 810, leaving a gap during riveting, so that the tip jaw 110 is rotatably connected to the movable jaw 210 to form a rotating structure; the two second tip jaw connecting holes 116 and the arc-shaped limiting hole 413 are connected by the second pin 820 connection, so that the tip jaw 110 is slidably connected with the limit plate 410, and the second pin 820 can slide along the curvature of the arc-shaped limit hole 413 to limit the opening and closing angle of the pliers head; the two second movable jaw connecting holes 214 and the first limit plate connecting hole 411 are pinned by the third pin 830, and the second limit plate connecting hole 412 and the two first connecting rod connecting holes 312 are pinned by the 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 limit plate 410 to form a driving structure for driving the pliers head to open and close; a 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 to form a driving structure for driving the connecting rod 310 to slide in the connecting tube 120, thereby opening or closing the pliers head.

[0071] The working process of the novel medical surgical wire passing forceps provided by the present invention is as follows:

[0072] The suture needle 710 is inserted into the tip tube 100, and the end groove 712 of the suture needle 710 is connected to one end of the palm operating rod 530 through a pin; the palm operating rod 530 is pressed to move toward the thumb operating rod 510, so that the suture needle 710 passes through the U-shaped notch of the tip jaw protrusion 111, and the suture thread is hung in the needle groove 711 of the suture needle 710, and the palm operating rod 530 is released. The first reset spring 910 takes effect, resets the palm operating rod 530, and the suture needle 710 drives the suture thread back into the needle-containing tube to complete the thread hanging operation.

[0073] The pressing structure 611 is lifted, and the finger operating rod 520 is pressed to move toward the thumb operating rod 510, so as to drive the pliers head to close and grasp the soft tissue. At this time, the limit buckle 612 is separated from the limit column 511, and the hook spring 930 is extended, so that the hook 610 and the ratchet 620 cooperate with each other to self-lock, thereby ensuring the locking state of the operating handle and keeping the pliers head closed; the palm operating rod 530 is pressed to move toward the thumb operating rod 510, so that the suture needle 710 drives the suture thread to pass through the U-shaped notch of the tip jaw protrusion 111, and after passing through one side of the soft tissue, the movable skylight 220 is pushed open to complete the threading operation; the palm operating rod 530 is released, and the first reset spring 910 acts to reset the palm operating rod 530 The suture needle 710 is in the position, and the suture needle 710 is retracted into the needle-containing tube. At the same time, the movable skylight 220 is closed with the movable jaw 210 under the action of the torsion spring, clamping the suture thread so that a part of the suture thread remains on the other side of the soft tissue; the pressing structure 611 is pressed, and the limiting buckle 612 is engaged with the limiting column 511, and the hook spring 930 is compressed to separate the hook 610 from the ratchet 620, and the hook 610 and the ratchet 620 are released from the self-locking state of the operating handle, and the second reset spring 920 works to reset the finger operating lever 520 to release the pliers head from the soft tissue; with the movable skylight 220 keeping the suture thread clamped, the wire-passing pliers are taken out, and the suture thread is taken out to complete the threading and threading operation.

[0074] The clamped suture is pulled upward to separate the movable sunroof 220 from the movable jaw 210, and the suture can move freely at this time; when the movable sunroof 220 is separated from the movable jaw 210, the suture is moved to the movable sunroof wire withdrawal groove 223. Since the suture has no upward pulling force on the head of the movable sunroof 220 at this time, the movable sunroof 220 will be closed again with the movable jaw 210 under the action of the torsion spring 230, and the suture is in the movable sunroof wire withdrawal groove 223; pull the suture downward to pull the suture out of the movable sunroof wire withdrawal groove 223 to complete the wire withdrawal operation.

[0075] The novel medical surgical wire-passing forceps provided by the present invention integrate the operations of tissue grasping, threading and wire removal, greatly simplify the surgical process, shorten the surgical time, avoid surgical errors, and improve the safety and efficiency of the operation; the handle self-locking design enables the operating handle to lock itself when grasped for a long time, reduces the doctor's force, facilitates the stretching operation, reduces surgical fatigue, and avoids the handle from falling off; the handle limit design effectively controls the suture needle stroke through the limit connecting rod, prevents the thread from being stuck, falling off, and damaging other soft tissues during needle threading, thereby ensuring the safety of the operation; the clamp head adopts high-strength and high-hardness metal materials to improve the mechanical strength and service life, and reduce the risk of medical accidents; the notch design on the right side of the movable skylight can facilitate the withdrawal of the suture while retaining the strength of the jaws to the greatest extent, avoiding the previous situation where the suture is forcibly pulled at the head of the movable skylight, resulting in the suture being damaged by the teeth of the head of the movable skylight, or the complicated operation of the movable skylight being difficult to open by hand to withdraw the line, thereby effectively improving the surgical efficiency and protecting the integrity of the suture; in addition, the ergonomic operating handle design based on the small and medium-sized hands of the Chinese can reduce the doctor's fatigue during long-term surgery and improve the user experience.
