[0005] The prior art WO2006098994A1 discloses a hair-running clip. The shortcoming of the hair-running clip is that multiple clips are connected end-to-end in sequence, and the control line is only connected to the most proximal clip. When a pulling force is applied to the farthest clip to release When the distal clips are used, the force needs to be transmitted through the subsequent clips. In order to effectively transmit the force to the distal clips and ensure that there is no disconnection between the rear clips, the connection strength between the rear clips needs to be gradually increased. If the most distal clip If it is not released successfully, the clip at the rear end is likely to fail due to excessive tension. At this time, the entire hemostatic clip assembly needs to be replaced. This situation will not only delay the operation time but also increase the cost of the patient.
In addition, when the most distal clip is released, the rear clips all bear a certain force, so the performance of the clips will be damaged, which will lead to inconsistent stability and reliability of each clip and affect the therapeutic effect
[0006] The prior art CN107280723A discloses a hair extension clip. The shortcoming of the hair extension clip is that the de

Example Embodiment

[0062] Example 1

[0063] Such as Figure 1-10 The first embodiment of the medical hemostatic clip of the present invention is shown, wherein the hemostatic clip is a continuous hair clip (such as figure 1 (Shown), there is a clip assembly (not shown in the figure) that includes two or more clips 1 arranged in an axial direction. Each clip 1 in the clip assembly is connected in series along the axial direction and can control the opening or opening of the most distal clip. A closed control wire 2, the clip 1 includes a clip body (not shown in the figure) and a clip base 14, the distal end of the control wire 2 is releasably connected to the clip body of the most distal clip 11; The child also includes a handle 3 located at the proximal end of the control wire 2 and used to control the control wire 2 to move back and forth in the axial direction, and a sheath 4, the control wire 2 extending along the inner cavity of the sheath 4 to control The proximal end of the wire is fixedly c...

Example Embodiment

[0078] Example 2

[0079] Such as Picture 12 As shown, the connection between the outer sheath and the inner sheath in Example 1 is changed. In the second embodiment, the proximal end of the outer sheath 41 and the outer wall of the second inner sheath 43 are directly and fixedly connected by the fixed connecting portion 71. Accordingly, the movement of the control wire can be used to control the release process. For the release of the most distal clip 11, the specific operation process can refer to the operation mode of using the control wire to release the clip in Embodiment 1, which will not be repeated here.

Example Embodiment

[0080] Example 3

[0081] Such as Figure 13 As shown, based on the basic structure of Embodiment 1, as an alternative, the outer sheath 41 and the inner sheath in this embodiment 4 are replaced by a relatively movable manner. In the process of releasing the most distal clip 11, the outer sheath 41 can also be moved. Specifically, in the process of releasing the clip, the release assembly is also detached from the release channel of the most distal clip 11, and then along Figure 13 As shown in the direction of the middle dotted line, by pulling the outer sheath proximally, the convex surface on the inner side of the limiting boss 51 is radially expanded by the radial and axial compression of the first inner sheath and then pulled to the distal end of the first inner sheath. End the outer periphery of the end and release the most distal clip 11. It can be seen that based on Example 1 and Example 3, the present invention can realize the release of the clip in two ways, and the ope...

Abstract

A medical hemostatic clip includes at least the following structures: a clip component, a control line, a handle and a sheath pipe; the clip component is connected in series through the control line in the axial direction, and the control line is moved to control opening or closing of a clip located at the most far end; the handle is used to control the control line to move forward and backward; and the far end of the sheath pipe has a limiting component, the near end side of the limiting component has a limiting space facing the axial direction of the sheath pipe, and at least a part of the clip located at the most far end is releasably limited in the limiting space by the limiting component. The medical hemostatic clip has the technical effects of repeatable opening and closing, rotationand the like.

Description

technical field [0001] The invention relates to a medical hemostatic clip, belonging to a medical device used in a human body. Background technique [0002] Endoscopy has been born for more than 50 years, and has gone through the stages from disease diagnosis to disease treatment. The treatment of specific diseases has been very effective and reliable, and has been widely used. The stomach and intestines of organisms often suffer from bleeding or mucosal damage, or even perforation, due to various diseases, accidental injuries, or injuries during endoscopic diagnosis and treatment. For active bleeding, drug spraying, high-frequency electrocautery burning, or mechanical compression with hemostatic clips are generally used for treatment. Among them, hemostatic clip mechanical compression hemostasis is more reliable for the treatment of active bleeding not caused by varicose veins, and has been generally recognized by doctors and patients. With the development of endoscopic he...
