[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the utility model and its application or use.
[0023] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.
[0024] See also Figure 1-3 As shown, in this embodiment, a hemostatic clip is provided, comprising: a left clamp 1, a right clamp 2, a first connection portion 3 and a second connection portion 4 respectively fixedly connected to the left clamp 1 and the right clamp 2, and two grasping handles 5 respectively fixedly connected to one end of the first connection portion 3 and the second connection portion 4, wherein the end of the grasping handle 5 is arranged as an extension structure, thereby enabling the ends of the two grasping handles 5 to be connected;
[0025] The first connection part 3 and the second connection part 4 cross and rotate with each other to drive the relative movement between the left clamp 1 and the right clamp 2 so that the silicone anti-skid pads on the left clamp 1 and the right clamp 2 fit tightly, thereby clamping the blood vessel and achieving the effect of hemostasis. By crossing and rotating the two connection parts, the heads of the two gripping handles 5 can be relatively close. This structure can make the clamping of blood vessels more accurate and precise, which can help doctors more effectively control the amount of blood loss during the operation and ensure the safety and success rate of the operation. The left clamp 1 and the right clamp 2 are both made of tungsten materials to ensure their safety and biocompatibility;
[0026] A groove is provided between the opposite sides of the inner walls of the two gripping handles 5, and a spring 6 is fixedly connected between the inner walls of the two grooves. The arrangement of the spring 6 enables the gripping handles 5 to provide resistance when in use, which greatly increases the stability of blood vessel clamping. The ends of the two gripping handles 5 are connected, and the ends of the two gripping handles 5 are V-shaped structures. Pressing the two gripping handles 5 can control the opening and closing of the ends of the two gripping parts 5, so as to adjust the opening and closing of the left clamp 1 and the right clamp 2. The spring 6 can also ensure the stability and controllability of the clamping of the left clamp 1 and the right clamp 2, making the left clamp 1 and the right clamp 2 more stable and reliable when in use, and improving the operator's work efficiency and precision.
[0027] In this embodiment, the left clamp 1 and the right clamp 2 are both arc-shaped structures. When the left clamp 1 and the right clamp 2 are in contact, the arc-shaped protruding part of the left clamp 1 will fit tightly into the arc-shaped recessed part of the right clamp 2. This clamp handle design allows the doctor to more effectively control the amount of blood loss during the operation and more easily control the clamping force, thereby clamping the blood vessel more accurately.
[0028] In this embodiment, the arc-shaped protruding part of the left clamp 1 and the arc-shaped recessed part of the right clamp 2 are fixedly connected with a plurality of silicone anti-skid pads. The provision of the silicone anti-skid pads increases the closure degree of the left clamp 1 and the right clamp 2 after they are combined, and reduces the gap after the left clamp 1 and the right clamp 2 are combined, thereby reducing the probability of the hemostatic clamp falling off and improving the clamping effect on the blood vessel.
[0029] In the present embodiment, the cross-section of the two gripping handles 5 is arc-shaped, and an elliptical cavity is formed when the two gripping handles 5 are fitted together. The width of the two gripping handles 5 after combination is greater than the width of the left clamp 1 and the right clamp 2 after combination. The two gripping handles 5 are fixedly connected with anti-slip grooves on the relatively distant sides, and the shape of the anti-slip grooves is a triangular structure. By adjusting the setting of the gripping handles 5, the user can hold the tool more easily and reduce hand fatigue and discomfort.
[0030] In this embodiment, notches are provided on opposite sides of the first connecting portion 3 and the second connecting portion 4. The depth of the notches is half of the left clamp 1 or the right clamp 2. The notches can make it easier to lay the hemostatic clamp flat when it is used, and it is not easy to damage the blood vessels.
[0031] The above-mentioned embodiments may be combined with each other.
