The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

The utility model provides a medical closing clip, which is formed by splicing the end parts of at least two closing clip parts 1, wherein the closing clip parts 1 comprise a connecting end and a clamping end which are connected with each other, and the connecting end of each closing clip part 1 is sequentially buckled end to form an annular structure; at least two clamping jaws 3 capable of being meshed with each other are correspondingly arranged at one end (namely a clamping end) in the width direction of the annular structure, the width direction refers to the direction parallel to the central axis of the annular structure, the clamping jaws 3 are made of shape memory materials such as nickel-titanium alloy, the buckling part 4 of the annular structure comprises a socket 6 positioned at one closed clamping part and a plug 5 positioned at the other adjacent closed clamping part, the plug 5 is suitable for being inserted into the socket 6 and mutually limited along the circumferential direction, and the buckling refers to the fact that the plug 5 and the socket 6 can be mutually limited when being connected.

The clip applying cap 21 (medical transparent mucosa suction cap) is a common accessory for endoscopic treatment, and is widely used for assisting hemostasis treatment, taking out foreign bodies, amplifying endoscopic examination, improving the tangent position and endoscopic imaging observation of pathological changes of difficult observation parts. Referring to fig. 5, before an actual operation is performed, a clamping cap 21 (a medical transparent mucosa suction cap) is sleeved on the outer periphery of the front end of a lens of an endoscope, a medical closing clamp is loaded on the clamping cap 21, at the moment, clamping jaws 3 are spread by the clamping cap 21, the medical closing clamp can enter a human body cavity along with the endoscope, and after the medical closing clamp is released to a target tissue, the clamping jaws 3 recover the original shape due to the shape memory property, so that the clamping jaws 3 of a plurality of closing clamp parts 1 are mutually engaged, and the target tissue is stably clamped, thereby achieving the purposes of closing a wound and stopping bleeding. The plug 5 and the socket 6 in the embodiment are buckled along the circumferential direction, namely are limited by relative movement along the circumferential direction; being connected with on the plug 5 and pulling wire 7, when pulling and pulling wire 7, plug 5 and socket 6 of mutual lock joint can separate, utilize the surgical instruments that possess the tractive ability such as taking out hook or sampling forceps, pull wire 7, drive plug 5 and break away from socket 6, and the link of two interconnect's closure clamp subsection 1 can part, and then makes the separation of clamping jaw 3 of meshing to can take out closure clamp subsection 1.

Ring structure in one embodiment of the present application, as shown in fig. 1-3, the medical closure clip is formed into a ring structure by the joining ends of two closure clip sections 1 joined end to end; the two closing clamping parts 1 are respectively provided with a clamping jaw 3, the clamping jaws 3 are made of shape memory materials such as nickel-titanium alloy, in a natural state, the two clamping jaws 3 can clamp human tissues when being closed, and in an external force action state, the two clamping jaws 3 are opened, and the natural state is a state without external force action. The resulting loop structure has two fastening sites 4 (fig. 3), the fastening sites 4 comprising a socket 6 at the connecting end of one of the closure clip portions 1 and a plug 5 at the connecting end of the adjacent other closure clip portion 1, the socket 6 being a recess at one of the circumferential ends of the connecting ends (fig. 4), the plug 5 being a projection at one of the circumferential ends of the connecting ends, the plug 5 being adapted to be inserted into the socket 6; the plug 5 and the socket 6 are preferably interlocked with each other in the circumferential direction, so that a circumferential limiting effect can be achieved. For the convenience of batch processing, the two closure clip subsections 1 have the same structure, the two ends of each closure clip subsection 1 are respectively provided with a plug 5 and a socket 6, the plug 5 on each buckling part 4 is connected with a pulling wire 7, one of the pulling wires 7 can be pulled to separate the two clamping jaws 3, one connecting end of the two closure clip subsections 1 is still connected by the buckling part 4, or the two pulling wires 7 are pulled to decompose the annular structure into the two independent closure clip subsections 1, and then the two closure clip subsections are taken out by using surgical instruments with pulling capability, such as a taking-out hook or a sampling clamp.

In alternative embodiments, the loop formation may be formed by three or four or more distinct closure pinch portions 1 joined end to end at the attachment end.

The inner surface of the socket 6 in this embodiment is an arc surface or a rectangular surface, the plug 5 and the socket 6 have the same shape, and when the inner surface of the socket 6 is an arc surface (as shown in fig. 1), the opening width of the socket 6 is smaller than the diameter of the plug 5 (as shown in fig. 2); when the inner surface of the socket 6 is a rectangular surface, the opening width of the socket 6 is smaller than the width of the plug 5.

In order to enable the plug 5 to be pulled outwards, it is preferred that the pulling wire 7 is located on the outer surface of the plug 5. In this embodiment, the plug 5 has two through wires 2 that link up, and two through wires 2 are connected at the both ends of tractive line 7 to form the tractive area between two through wires 2, it can directly hook the tractive line 7 between two through wires 2 to take out the surgical instruments that possess tractive ability such as hook or sampling forceps.

If the socket 6 is not through the circumferential outer surface and the circumferential inner surface of the ring structure, the plug 5 is wrapped by the socket 6, and a certain staggered space is required in the thickness direction of the plug 5 and the socket 6 at this time, so that the plug 5 can be moved in the thickness direction and then is released from the buckling relation with the socket 6, and in order to make the plug 5 more easily pulled, the socket 6 preferably extends to the circumferential outer surface of the ring structure, so that the outer surface of the plug 5 can be exposed, and at this time, the plug 5 can be moved outward by pulling the pulling wire 7 outward, so as to be separated from the socket 6.

The socket 6 may or may not pass through the circumferential inner surface of the ring structure, and when the socket 6 passes through the circumferential inner surface of the ring structure, the plug 5 and the socket 6 simultaneously contact the human tissue, and the expansion force of the human tissue on the plug 5 and the socket 6 may be different, which may cause the plug 5 and the socket 6 to be staggered and separated, for this reason, preferably, the socket 6 does not extend to the circumferential inner surface of the ring structure, that is, the socket 6 does not pass through the inner circumferential surface of the closure clip part 1, so the plug 5 does not contact the human tissue, and when the expansion force of the human tissue is applied, the plug 5 and the socket 6 at the same fastening part 4 are synchronously expanded, and the fastening force of the plug 5 and the socket 6 is gradually increased in the circumferential direction, and the plug 5 does not automatically separate from the socket 6.

In this specification, the schematic representations of the terms are not necessarily referring to the same embodiment. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
