According to the tissue closing clip 100 provided by the embodiment of the invention, the clip arm 30 is positioned between the first pressure arm 10 and the second pressure arm 20, the proximal end of the tissue closing clip 100 can be adjusted in a plastic deformation mode on the basis that the first pressure arm 10 is connected with the proximal end of the second pressure arm 20, the clip arm 30 has a force biasing the second pressure arm 20 on the basis that the clip arm 30 is connected with the first pressure arm 10 in a distal end, and then the clip arm 30 is in elastic contact with the second pressure arm 20, after the tissue closing clip 100 is conveyed into a human body through a special conveying device and opened, a tissue 70 to be clipped, such as a left atrial appendage, is placed between the clip arm 30 and the second pressure arm 20, and then the tissue closing clip 100 is released, so that the clip arm 30 and the second pressure arm 20 are mutually closed to clamp the tissue 70.
As shown in fig. 1 and 2, the first pressing arm 10 and the second pressing arm 20 of the tissue closing clip 100 in this embodiment are symmetrically disposed, and the first pressing arm 10 and the second pressing arm 20 are connected at the proximal end, so as to form a U-shaped closing clip body, and the closing clip body can be opened and closed along with the distal distance and approaching of the first pressing arm 10 and the second pressing arm 20. The tissue closure clip 100 in this embodiment may be made of elastic materials with good biocompatibility such as medical stainless steel, nickel-titanium alloy, titanium alloy (e.g. TC4, TC 20), etc. by means of wire cutting, electric spark, machining, etc.
