Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and more particularly to a wire grabbing forceps. Background Art

[0002] Arthroscopic surgery is different from conventional surgery. It is an operation performed on lesions or damaged structures in the joint cavity under a microscope. It is a highly technical operation with great difficulty and high requirements. Sutures are needed when suturing the incisions in the joints. When suturing, since it is a moving operation inside the body, the sutures need to be grasped during the operation. In the current arthroscopic surgery, wire graspers are mostly used to grasp the sutures to drive the sutures to move for suturing operations.

[0003] At present, conventional wire graspers are generally used to grasp one wire before grasping another wire, which often results in the already grasped wire easily slipping out of the wire grasper when grasping another wire after grasping one wire, increasing the time of the surgical operation. Too long an operation time will have an impact on the patient's health, so it is crucial to improve the efficiency of the operation.

[0004] In order to meet the current clinical needs, a smaller wire grasping forceps is needed to meet the needs of smooth wire grasping and pulling fixation. Summary of the invention

[0005] The purpose of the invention is to design and develop a wire grasping forceps, which is more convenient to grasp the suture thread and improve the operation efficiency through the platform design of the forceps head.

[0006] The technical solution provided by the present invention is:

[0007] A wire grabber, comprising:

[0008] a tip tube assembly; and

[0009] a connecting rod slidably disposed within the tip tube assembly;

[0010] A movable jaw, one end of which cooperates with one end of the tip tube assembly to form a jaw head, and the other end of which is connected to the connecting rod;

[0011] Wherein, a platform is arranged at the contact point between one end of the movable jaw and one end of the tip tube assembly.

[0012] Preferably, the tip tube assembly comprises:

[0013] A fixed tube, one end of which is connected to the handle assembly;

[0014] A pointed end portion, which is in an arc-shaped structure, and one end of the pointed end portion is integrally arranged with the other end of the fixed tube on one side of the circumference;

[0015] A connecting groove is arranged at the other end of the fixed tube near the sharp end, and the connecting groove is arranged opposite to the sharp end, and the connecting groove is connected to the interior of the fixed tube;

[0016] Wherein, the other end of the pointed port cooperates with the movable jaw to form a clamp head.

[0017] Preferably, the movable jaw comprises an integrally formed jaw end and a connecting end;

[0018] The jaw end is in an arc-shaped structure, and a cavity is formed inside when the jaw end and the pointed end are closed, and the connecting end is a symmetrically arranged plate-shaped structure.

[0019] Preferably, it also includes:

[0020] A first rotating pin is riveted through both sides of the connecting groove.

[0021] Preferably, it also includes:

[0022] A first through hole, which is symmetrically arranged on both sides of the bottom of the connecting end;

[0023] A second rotating pin is fixed through both sides of the top of the connecting end, and the second rotating pin is centrally symmetrical with the first through hole;

[0024] Wherein, the first through hole is rotatably sleeved on the first rotating pin.

[0025] Preferably, a second through hole is provided on one end of the connecting rod, and the second through hole is rotatably sleeved on the second rotating pin.

[0026] Preferably, it also includes:

[0027] A card slot, which is arranged at one end of the connecting rod, and the card slot is arranged opposite to the second through hole;

[0028] Wherein, the slot can be selectively engaged with the first rotating pin, and when the slot is engaged with the first rotating pin, the jaw end and the pointed end are in a closed state.

[0029] Preferably, it also includes:

[0030] A thumb end connected to one end of the fixed tube;

[0031] The finger end is rotatably connected to the thumb end, and the finger end is connected to the other end of the connecting rod, so as to selectively pull or push the connecting rod to move forward and backward in the fixed tube.

[0032] Preferably, when the jaw end and the pointed end are closed, a teardrop-shaped cavity is formed inside, and the head of the teardrop-shaped cavity is close to the connecting end.

[0033] Preferably, a platform is provided at the contact point between the other end of the pointed end and the jaw end.

[0034] The beneficial effects of the present invention are:

[0035] The wire grasping forceps designed and developed by the present invention have a platform design of the forceps head, which makes it easier to grasp the sutures, thereby grabbing the sutures. Combined with the cavity structure of the forceps head, a closed loop can be formed, allowing multiple sutures to slide freely in the cavity, and can limit the positions of the multiple sutures, thereby achieving traction of the multiple sutures. The small diameter and low profile of the overall structure can ensure that the wire grasping forceps can enter the tightest joint space. The pin transmission structure of the forceps head ensures the mechanical strength and service life of the wire grasping forceps, ensures that the jaws will not break, reduces surgical operation time, improves surgical efficiency, and reduces the risk of medical accidents.

[0052] like Figure 6 As shown, the movable jaw 120 includes an integrally formed jaw end 121 and a connecting end 122, the jaw end 121 is an arc-shaped structure, and the jaw end 121 and the pointed end 112 have basically the same structure, and a cavity is formed inside when the jaw end 121 and the pointed end 112 are closed, and the connecting end 122 is a symmetrically arranged plate-like structure.

[0053] like Figure 7 As shown, the connecting rod 130 is slidably disposed in the fixing tube 111 , and the other end of the connecting rod 130 is connected to the handle assembly.

[0054] like Figure 3-Figure 7 As shown, third through holes are symmetrically arranged on both sides of the connecting groove 113, and a first rotating pin 151 is riveted through the third through holes on both sides of the connecting groove. Symmetrical first through holes 153 are arranged on both sides of the bottom of the connecting end 122 close to the tip tube assembly 110, and the movable jaw 120 can rotate relative to the tip end 112 by being rotatably sleeved on the first rotating pin 151 through the first through holes 153; symmetrical fourth through holes 154 are arranged on both sides of the top of the connecting end 122 away from the tip tube assembly 110, and the fourth through holes 154 and the first through holes 153 are centrally symmetrical, and a second through hole 155 is arranged at one end of the connecting rod 130, and the second rotating pin 152 is penetrated and fixed in the fourth through hole 154 of the connecting end, and is rotatably sleeved on the second rotating pin through the second through hole 155, and the connecting rod 130 can pull the movable jaw 120 to open and close toward the tip end 112.

[0055] A slot 131 is provided at one end of the connecting rod 130, and the slot 131 is arranged opposite to the second through hole 155. The slot 131 can be selectively engaged with the first rotating pin 151, and when the slot 131 is engaged with the first rotating pin 151, the jaw end 121 and the pointed end 112 are in a closed state, thereby realizing the closed limit of the jaw head.

[0056] The handle assembly includes: a thumb end 141 and a finger end 142, the thumb end 141 is connected to one end of the fixed tube 111; the finger end 142 and the thumb end 141 are rotatably connected to each other through a handle pin, and the finger end 142 is fixedly connected to the other end of the connecting rod 130 through a shear pin, which is used to selectively pull or push the connecting rod 130 to move forward and backward in the fixed tube 111.

[0057] like Figure 8 , Fig. 9 As shown, in order to enable the wire grabber to enter the tightest joint space, the outer sides of the jaw end 121 and the pointed end 112 are inclined, and the maximum outer inclination angle of the jaw end 121 and the pointed end 112 does not exceed 90°. The maximum height of the clamp head of the wire grabber does not exceed 4 mm, and the maximum width of the clamp head does not exceed 2 mm, so that the wire grabber has the characteristics of small diameter and low profile.

[0058] like Fig.10 As shown, in this embodiment, a platform is provided at the contact point between the other end of the pointed end 112 and the jaw end 121, which can be used for conventional grasping work to firmly grasp the suture and thus grab the suture.

[0059] like Fig.11As shown, in this embodiment, when the jaw end 121 and the pointed end 112 are closed, a teardrop-shaped cavity is formed inside, and the head of the teardrop-shaped cavity is close to the connecting end 122, allowing multiple sutures to slide freely in the cavity when the sutures are taken out, thereby pulling the multiple sutures at the same time.

[0060] The working process of the wire grabbing pliers described in the present invention is as follows: the connecting end and the tip end are riveted to form a rotating structure, and at the same time, the connecting end is pinned to a connecting rod to form a driving structure. Through the movable jaws, the tip tube assembly is connected to the connecting rod to form a pliers head shearing structure. The finger ends are connected to the connecting rod through pins to form a driving structure. The thumb end and the finger end are held, and the finger end is driven to rotate around the handle pin. The connecting rod is driven through the shear pin to make the jaws movable to form a rotating structure.

[0061] The shape and spacing of the handles of the wire grabber described in the present invention are designed according to the small and medium-sized hands of Chinese people. The ergonomic design can better reduce fatigue during long-term surgical card clearing. High-strength and high-hardness metal is used in the jaw part, which will not break, effectively improving the mechanical strength and service life, ensuring that the jaw will not break and remain in the cavity, and greatly reducing the risk of medical accidents.

[0062] The wire grasping forceps designed and developed by the present invention have a platform design of the forceps head, which makes it easier to grasp the sutures, thereby grabbing the sutures. Combined with the cavity structure of the forceps head, a closed loop can be formed, allowing multiple sutures to slide freely in the cavity, and can limit the positions of the multiple sutures, thereby achieving traction of the multiple sutures. The small diameter and low profile of the overall structure can ensure that the wire grasping forceps can enter the tightest joint space. The pin transmission structure of the forceps head ensures the mechanical strength and service life of the wire grasping forceps, ensures that the jaws will not break, reduces surgical operation time, improves surgical efficiency, and reduces the risk of medical accidents.

[0063] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
