[0002] Surgical right-angle forceps is a commonly used tool in surgery, mainly used to free and bypass major blood vessels, bile ducts and other tissues. According to the different materials used, surgical right-angle forceps can be divided into stainless steel and other materials. In surgery, it is mainly used to clamp and stabilize tissues to facilitate cutting, ligation or hemostasis. It can also be used for delicate separation operations to help surgeons complete surgical operations accurately and quickly. Right-angle forceps is one of the indispensable tools in surgery.

[0003] The shortcomings of the prior art: The surgical right-angle pliers in the prior art usually have a right angle at the pliers head, and the right angle is usually lengthened. When the surgical incision is small, it is very inconvenient for the lengthened right-angle pliers head to enter the incision. At the same time, the lengthened part is easy to cause obstruction, affecting the doctor's line of sight during the operation. At the same time, the clamping end of the existing right-angle pliers head will be deformed after long-term use, resulting in a gap in the closure of the right-angle pliers when used, affecting the use effect.

In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The surgical right-angle forceps involved in the present invention are not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0020] The utility model provides a surgical right-angle forceps, such as Figure 1 and Figure 2 As shown, it includes a first finger ring 1 and a second finger ring 2, a first serrated buckle 3 is fixedly connected to one side of the right end of the first finger ring 1, and a second serrated buckle 4 is fixedly connected to one side of the left end of the second finger ring 2, the positions of the first serrated buckle 3 and the second serrated buckle 4 correspond to each other, and the first serrated buckle 3 and the second serrated buckle 4 are movably connected to each other, and the clamping degree of the surgical forceps is adjusted by the buckling of different numbers of serrations provided on the surfaces of the first serrated buckle 3 and the second serrated buckle 4, so that the closure of the right-angle forceps is tighter, the front ends of the first finger ring 1 and the second finger ring 2 are fixedly connected to a first clamp arm 5, and one end of the first clamp arm 5 away from the first finger ring 1 and the second finger ring 2 is rotatably connected to a connecting component 6, and one end of the connecting component 6 away from the first clamp arm 5 is fixedly connected to a second clamp arm 7, and the doctor holds the first finger ring 1 and the second finger ring 2 to drive the first clamp arm 5 and the second clamp arm 7 to move.

[0021] Furthermore, one end of the second clamp arm 7 away from the connecting component 6 is fixedly connected to a connecting block 8, a clamp head 9 is fixedly connected to the front end of the connecting block 8, a serrated block 10 is fixedly connected to the inner wall of the clamp head 9, the front ends of the two clamp heads 9 are respectively fixedly connected to a first clamp block 11 and a second clamp block 12, and connecting grooves 13 are provided inside the two connecting blocks 8. The connecting grooves 13 ensure the tightness and stability of the connection between the two connecting blocks 8, and a rotating shaft 14 is fixedly connected to the middle of the inner cavity of the connecting groove 13. The positions of the two connecting blocks 8 correspond to each other, and the two connecting blocks 8 are rotatably connected through the rotating shaft 14.

[0022] Further, such as Figure 3As shown, the connecting assembly 6 includes a first rotating connecting member 61 and a second rotating connecting member 62, and the first rotating connecting member 61 and the second rotating connecting member 62 are rotatably connected to each other. The rear end of the first rotating connecting member 61 is fixedly connected to the front end of the first forceps arm 5, and the front end of the second rotating connecting member 62 is fixedly connected to the rear end of the second forceps arm 7. The surgical forceps are changed into a right angle by the rotation between the first rotating connecting member 61 and the second rotating connecting member 62. At the same time, the rotation between the first rotating connecting member 61 and the second rotating connecting member 62 is a damping rotation, which is beneficial to control the rotation of the connecting assembly 6, generate a certain resistance, and ensure the stability of the surgical forceps. The left and right ends of the first rotating connecting member 61 and the second rotating connecting member 62 are both rotatably connected to the limit block 63, and the limit block 63 is used to ensure the stability of the surgical forceps when bending.

[0023] Further, such as Figure 4 As shown, the first clamping block 11 and the second clamping block 12 are adapted in shape and size, and a serrated block 10 is provided at the forceps head 9 to ensure that when the two forceps heads 9 are closed, the object is clamped firmly and the friction is increased. The first clamping block 11 and the second clamping block 12 are movably connected to each other to prevent the surgical forceps from being deformed after long-term use, resulting in a gap between the two forceps heads 9 when closed.

[0024] The working principle of the utility model is as follows: the user takes the surgical forceps through the first finger ring 1 and the second finger ring 2, and by moving the first finger ring 1 and the second finger ring 2, the first forceps arm 5 and the second forceps arm 7 are driven to move. The first forceps arm 5 and the second forceps arm 7 are connected to each other through the connecting block 8 and the connecting groove 13. The first forceps arm 5 and the second forceps arm 7 are rotated relative to each other through the rotating shaft 14, driving the two forceps heads 9 to close each other. When a right-angle operation is required, the surgical forceps are turned into a right angle by rotating the first rotating connecting member 61 and the second rotating connecting member 62. The first rotating connecting member 61 and the second rotating connecting member 62 are rotated relative to each other. The rotation between the dynamic connecting member 61 and the second rotating connecting member 62 is a damping rotation, which is beneficial to controlling the rotation of the connecting component 6, generating a certain resistance, and ensuring the stability of the surgical forceps. During the clamping process using the forceps head 9, the friction force is increased by the serrated block 10 provided at the forceps head 9. The first clamp block 11 and the second clamp block 12 at the front end of the forceps head 9 can prevent the surgical forceps from being deformed after long-term use, resulting in a gap in the closure between the two forceps heads 9. The longer bent front end allows the surgical forceps to better enter smaller surgical incisions while reducing obstruction of the line of sight.
