Embodiment 1

[0033] Combine figure 1 with figure 2 As shown, a double-locking tissue clip with a limit protection device includes an operating handle 1 with a sliding cavity 2 and a slider 3 slidably connected to the sliding cavity 2. Preferably, the slider 3 can be connected to the sleeve The sliding sleeve provided on the surface of the operating handle 1 is fixedly connected to facilitate the sliding of the slider 3. One end of the metal wire 5 is fixedly connected with the slider 3, and the other end is connected with the opening adjustment mechanism 7 which can adjust the opening of the clip 4 The connection between the metal wire 5 and the opening adjustment mechanism 7 has an upper limit of force. When the slider 3 is further slid so that the force between the wire 5 and the opening adjustment mechanism 7 is greater than the upper limit of the force, the wire 5 Separate from the opening adjustment mechanism 7, that is, from the clip 4, it also includes a locking mechanism 6 that keep...

Embodiment 2

[0043] The specific structure in this embodiment is substantially the same as the specific structure in Embodiment 1. The difference lies in the structure of the limit protection mechanism 8. Specifically, the limit protection mechanism 8 includes a T-shaped block 81. There is a pin hole 82 in the middle of the block 81. The pin shaft passes through the pin hole 82 so that the T-shaped block 81 is rotatably connected in the sliding cavity 2. When the T-shaped block 81 is rotated to the side close to the slider 3, the slider 3 will It is pressed on the T-shaped block 81 without causing the clip 4 to fall off. When the T-shaped block 81 is rotated to the side away from the slider 3, the slider 3 can continue to slide for a certain distance to make the clip 4 fall off.

Embodiment 3

[0045] The specific structure in this embodiment is substantially the same as the specific structure in Embodiment 1. The difference lies in the structure of the limit protection mechanism 8. Specifically, the limit protection mechanism 8 includes two ends connected by an arc structure. , One end extends into the sliding cavity 2 and is in interference fit with the sliding cavity 2, and the arc-shaped structure fits the outer surface of the operating handle 1.

[0046] It is similar to the principle that the limit protection mechanism 8 realizes the limit in Embodiment 1, so it will not be repeated here.

Abstract

The invention relates to the technical field of medical devices, in particular to a double locking tissue clip with a limit protection device. The clip comprises an operating handle with a sliding cavity inside and a sliding block in sliding connection with the sliding cavity. One end of a metal wire is fixedly connected with the sliding block, and the other end is connected with an opening adjustment mechanism capable of adjusting the opening degree of the clip. The clip further comprises a locking mechanism enabling the clip to be maintained in the clamping state, and the locking mechanism is arranged on the clip. The clip comprises the locking mechanism arranged on the clip and enabling the clip to be maintained in the clamping state, so that the locking can still hold the clip in a locked state for a long time after the clip breaks away from an operation handle and is reserved in vivo to prevent the clip from being loosed and falling off, leading to secondary bleeding caused by insufficient locking time. Further, the clip is provided with the limit protection device, and accidental falling of the clip caused by excessive force during the clamping process or instrument testing before the surgery is avoided.

Description

Technical field [0001] The invention relates to the technical field of medical equipment and devices, in particular to a double-locking tissue clip with a limit protection device. Background technique [0002] In recent years, endoscopic hemostatic clips have become the most effective non-surgical treatment for acute gastrointestinal bleeding in critically ill patients and have the most clinical application value due to their characteristics of low trauma, fast hemostasis, low incidence of rebleeding, few complications, and definite curative effect. Methods. Endoscopic metal clip hemostasis is one of the more widely used methods of hemostasis. Performing skilled metal clip operations on appropriate cases can effectively stop bleeding and prevent rebleeding, reduce adverse reactions, and greatly improve the safety and safety of endoscopic treatment of gastrointestinal bleeding. Cure rate. The hemostatic mechanism of the metal hemostatic clip is the same as that of surgical blood...
