Embodiment 1

[0031] see figure 1 As shown, a hemostatic clip according to the present invention that can clean up bleeding points includes a clip 1 , a conveying part 2 , a bleeding cleaning part and a control part 5 .

[0032] Wherein, the clip 1 includes a pair of clips 11 and a tightening tube 12 that can press the clips together. The clip 11 can clamp the biological tissue, and can be made of elastic metal material or polymer material with certain hardness and strength; Hold tissue. The assembly method of the clip 11 and the tightening tube 12 can adopt the conventional method in the existing hemostatic clip, as long as the tightening tube 12 can realize the function of compressing the clip, for example, the clip can be set as the rear end The structure of the thin arm and the thick distal arm can form a stopper at the junction of the clip 11 and the tightening tube 12, so that the stopper can withstand the tightening tube after the clip 11 is stored at a certain position backend. ...

Embodiment 2

[0044] see Figure 4 , 5 As shown, the hemostatic clip of embodiment 2 has been improved on the basis of embodiment 1, and the delivery part 2 is also provided with a delivery tube 26, and the delivery tube 26 is sleeved on the outside of the clip 1 and the flexible tube 22 so that the clip 1 and the flexible tube 22 runs through it. In this embodiment, the injection port 41 is located at the rear end of the delivery tube 26 , the medium channel is formed between the inner wall of the delivery tube 26 and the outer wall of the flexible tube 22 , and the outlet is located at the front end of the inner wall of the delivery tube 26 .

[0045] In addition, the rear end of the delivery tube 26 is provided with a seal 261 to seal the delivery tube 26 and the insulating layer 221 on the outside of the flexible tube 22 to prevent media such as liquid from splashing toward the handle end. The seal is made of elastic materials such as silica gel or rubber TPU, and its inner hole is ro...

Embodiment 3

[0049] The hemostatic clip of embodiment 3 has been improved on the basis of embodiment 1, as Figure 7 As shown, the delivery part 2 also includes a delivery tube 26', the injection port 41 is located on the delivery tube 26', and the delivery tube 26' is located outside the flexible tube 22.

[0050] The delivery tube 26' can be set as a separate hollow channel, which itself can be used as a medium channel, which can be used to transport media such as liquids, and can also be used to pass into guided instruments to guide the hemostatic clip into more difficult-to-reach lesion positions or narrower areas. Hemostasis in the body cavity. The delivery pipe 26' is connected to the insulating layer of the flexible pipe 22, and it can be an integral structure or connected together through processes such as bonding and welding. The injection port 41 communicates with the delivery pipe 26' of the separate cavity. When the injection port is connected with a syringe of a medium such a...

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a hemostatic clip capable of transporting liquid and other media to treat wounds and capable of cleaning bleeding spots. Background technique [0002] The stomach and intestines of organisms often cause bleeding due to various diseases or accidental injuries or injuries after endoscopic treatment. For active bleeding, drugs are generally sprayed, or high-frequency electricity, laser, argon gas burning and hemostasis methods are used. Hemostatic clips Mechanical compression to stop bleeding and other methods for treatment. Among them, the mechanical hemostasis of the hemostatic clip is more reliable for the treatment of active bleeding caused by non-varicose veins, and has also been recognized by doctors and patients; The wound opening can promote wound healing and avoid laparotomy. But at present, if you use a hemostatic clip for hemostasis, you can only clamp and com...
