Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to an open clamp applicator capable of quickly distinguishing the type of a hemostatic clip by the color of a finger ring. Background Art

[0002] A clip applier is a medical device used to stop bleeding from a patient's blood vessels or tissues. The front end of the clip applier is used to clamp the hemostatic clip, which can accurately and effectively clamp the blood vessels or tissues to achieve hemostasis. In surgical operations, different blood vessels also require different types of clip appliers to clamp different types of hemostatic clips to achieve hemostasis. The ability to quickly identify the type of hemostatic clip is also conducive to faster hemostasis during surgery. However, conventional clip appliers do not have the function of helping to identify the type of hemostatic clip. Different sizes of human blood vessels require different sizes of hemostatic clips. The identification of hemostatic clips usually depends on the experience of doctors and nurses, which increases the difficulty of surgery. In addition, existing clip appliers lack a rebound structure and rely on the operator to manually open the clip applier to loosen it, which is more laborious and affects the operating experience. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and to provide an open clamp applicator that can quickly distinguish the type of hemostatic clip by the color of the finger ring. The open clamp applicator can automatically rebound and release, and the operation is smooth and labor-saving. At the same time, the suitable hemostatic clip model can be distinguished according to the color of the finger ring.

[0004] The purpose of the utility model is achieved through the following technical solution: the open clamp applicator which can quickly distinguish the type of hemostatic clip by the color of the finger ring comprises:

[0005] A first clamp rod, one end of which is provided with a first clamp head, and the other end of which is provided with a first finger ring;

DETAILED DESCRIPTION

[0021] The utility model will be described in detail below with reference to the accompanying drawings:

[0022] Example: As attached Figure 1 , 2 As shown, this open clamp forceps that can quickly distinguish the type of hemostatic clip by the color of the finger ring includes a first clamp rod 1, a first clamp head 11, a first finger ring 12, a second clamp rod 2, a second clamp head 21, a second finger ring 22, a pin hole 3, a rotating pin 31, a limiting groove 4, a limiting pin 41, a spring screw 5, a spring sheet 6, a latch 7 and an anti-slip film 8.

[0023] Reference Figure 1 A first clamp head 11 is provided at the front end of the first clamp rod 1, and a first finger ring 12 is provided at the rear end of the first clamp rod 1. A second clamp head 21 is provided at the front end of the second clamp rod 2, and a second finger ring 22 is provided at the rear end of the second clamp rod 2. A pin hole 3 is provided on each of the first clamp head 11 and the second clamp head 21, and a rotating pin 31 is installed in the pin hole 3 to realize the hinge connection between the first clamp rod 1 and the second clamp rod 2. One end of the spring sheet 6 (as a rebound mechanism) is fixedly connected to the second clamp rod 2 by a spring screw 5, and a slot is provided at the other end of the spring sheet 6. At the same time, a latch 7 is provided at the rear end of the first clamp rod 1, and the latch 7 is inserted into the slot to realize the connection and fixation. When the first finger ring 12 and the second finger ring 22 are released, the spring sheet 6 can apply a rebound force to the first clamp rod 1 and the second clamp rod 2, so that they automatically rebound and open. Preferably, the spring sheet 6 is in an arc shape.

[0024] Furthermore, a layer of anti-slip film 8 is coated on the first finger ring 12 and the second finger ring 22, and the anti-slip film 8 has colors (as color indication areas), and different colors can be set on the anti-slip film 8 to indicate the type of hemostatic clip that the clip applier is adapted to. The colors can be quickly distinguished during surgery, making the surgery smooth and efficient.

[0025] like Figure 2 As shown, a limit groove 4 (preferably arc-shaped) is provided on the first clamp 11, and the limit groove 4 can cooperate with a limit pin 41 provided on the second clamp 21, so as to limit the opening angle of the first clamp 11 relative to the second clamp 21, and effectively prevent the clamp from being damaged due to excessive opening.

[0026] The working process of the utility model is as follows: before or during surgery, the model of the hemostatic clip corresponding to the clamp is determined according to the color of the anti-slip film 8 on the first finger ring 12 and the second finger ring 22. After selecting the appropriate clamp, the surgical operation can be performed. During the operation, the first clamp head 11 and the second clamp head 21 are clamped by pressing the first finger ring 12 and the second finger ring 22, so that the hemostatic clip is clamped. When the hemostatic clip needs to be loosened, the first finger ring 12 and the second finger ring 22 are opened, and the spring sheet 6 provides the rebound force to bounce the first clamp rod 1 and the second clamp rod 2 relatively apart, which saves effort. At the same time, the limit pin 41 slides in the limit groove 4 to limit the angle at which the first clamp head 11 opens to the second clamp head 21, preventing damage due to excessive opening.

[0027] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and the concept of the utility model should fall within the protection scope of the claims attached to the utility model.
