Obviously, the described embodiments are some embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] As Figures 1 to 3 shown, a metal clip that can be adjusted in direction and angle for use with an endoscope in the first aspect embodiment of the present utility model includes a connecting rod 1, a connecting member 12, a clip head 2, a steering control mechanism 6, and a clip head opening and closing control mechanism 7. One end of the connecting member 12 is rotatably connected to one end of the connecting rod 1, and the other end of the connecting member 12 is detachably connected to the clip head 2. After the clip head 2 is used to complete clamping and hemostasis, the clip head 2 can be released from the connecting member 12, and the release method between the connecting member 12 and the clip head 2 can adopt the corresponding structure in the prior art; the steering control mechanism 6 and the clip head opening and closing control mechanism 7 are arranged at the end of the connecting rod 1 away from the connecting member 12. The steering control mechanism 6 is used to control the turning of the clip head 2, and the clip head opening and closing control mechanism 7 is used to control the opening and closing of the clip head 2.

[0026] The chuck 2 includes a first clamping arm 9 and a second clamping arm 10. One end of the first clamping arm 9 is hinged to the second clamping arm 10. An anti-slip mechanism 11 is provided on the side of the first clamping arm 9 facing the second clamping arm 10, and an anti-slip mechanism 11 is provided on the side of the second clamping arm 10 facing the first clamping arm 9. After the chuck 2 is closed, that is, after the first clamping arm 9 and the second clamping arm 10 are in contact, the anti-slip mechanism 11 on the first clamping arm 9 and the anti-slip mechanism 11 on the second clamping arm 10 engage with each other to prevent slipping.

[0027] In this embodiment, it should be noted that the anti-slip mechanism 11 is an anti-slip protrusion. The chuck opening and closing control mechanism 7 can adopt the corresponding mechanism in the existing hemostatic clip, and it only needs to be able to control the opening and closing of the chuck 2; the connecting rod 1 is made of a flexible material and is bendable.

[0028] The technical effects achieved by this embodiment are as follows: By setting the steering control mechanism 6, the chuck 2 can be controlled to turn during use, which is suitable for multi-angle operations and is easier to operate; the first clamping arm 9 and the second clamping arm 10 are respectively provided with anti-slip mechanisms 11, and they are not easy to slip off after engagement, which can effectively ensure the smooth progress of the operation.

[0029] Embodiment 2

[0030] As Figures 1 to 3 shown, another metal clip with adjustable direction and angle for use with an endoscope provided in this embodiment includes all the contents of Embodiment 1, and only the different parts will be described below.

[0031] In this embodiment, the steering control mechanism 6 includes a pulling rope 5, a sliding sleeve, and an elastic reset member 4. The connecting member 12 and the connecting rod 1 are rotatably connected through a rotating shaft 3;

[0032] The pulling rope 5 is arranged along the length direction of the connecting rod 1. One end of the pulling rope 5 is connected to the connecting member 12, and the other end of the pulling rope 5 is connected to the sliding sleeve. The sliding sleeve is slidably arranged at one end of the connecting rod 1 away from the chuck 2.

[0033] In this embodiment, it should be noted that the elastic reset member 4 is a spring piece. The sliding sleeve is slidably sleeved on the connecting rod 1 along the length direction of the connecting rod 1, and a return spring is provided between the sliding sleeve and the connecting rod 1.

[0034] The principle of the steering control mechanism 6 for controlling the turning of the chuck 2 is as follows. During use, by sliding the sliding sleeve in the direction away from the chuck 2, the pulling rope 5 can be dragged, so as to drag the connecting member 12 to rotate along the rotating shaft 3 through the pulling rope 5. When the connecting member 12 rotates, it drives the chuck 2 to rotate. After rotating to an appropriate angle, the chuck 2 can be controlled to close by the chuck opening and closing control mechanism 7 for hemostasis operation.

[0035] The technical effects achieved in this embodiment are as follows: The steering control mechanism 6 has a simple structure and is easy to operate. During use, it can conveniently control the steering and reset of the chuck 2, greatly improving the efficiency of surgical operations.

[0038] In this embodiment, an elastic restraint sleeve is further included. The elastic restraint sleeve is sleeved on the connecting rod 1 and is used to restrain the pulling rope 5 on the side wall of the connecting rod 1. Specifically, the elastic restraint sleeve can be a mesh-shaped elastic sleeve. During use, the elastic restraint sleeve makes the pulling rope 5 fit on the outer side wall of the connecting rod 1, so that the pulling rope 5 can bend accordingly as the connecting rod 1 bends, but does not affect the sliding sleeve's pulling of the pulling rope 5.

[0039] In this embodiment, it should be noted that the pulling rope 5 is made of nylon rope, which is more durable.

[0040] The technical effects achieved in this embodiment are as follows: By setting the elastic restraint sleeve, the smooth and normal operation of the entire steering control mechanism 6 can be ensured.
