Embodiment 1

[0044] Example 1, such as Figure 1-Figure 7 As shown, a kind of anastomotic clip is provided, including carrier transparent cap 1, fixing clip 2 and push rod 3, carrier transparent cap 1 axially penetrates, carrier transparent cap 1 is sleeved on the front end of endoscope 8, and carrier transparent cap 1 The front end is provided with a fixing clip accommodation chamber 101, and the rear end is provided with a pushing chamber 102; the pushing chamber 102 communicates with the fixing clip accommodation chamber 101; The push chamber 102 is positioned at the outside of the endoscope 8, when the push rod 3 is pushed forward (that is, the push rod 3 is pushed to the front end of the endoscope 8), the clip 2 stretches out from the clip accommodating chamber 101, and the clip The front end of 2 is tightened toward the longitudinal central axis direction of fixing clip 2, and fixing clip 2 clamps diseased tissue 7 at this moment.

[0045] The carrier transparent cap 1 has a tubular...

Embodiment 2

[0051] Embodiment 2, a kind of matching suit, such as Figure 8-Figure 11 , Figure 14-Figure 19 As shown, it includes the pulling clip 6 and the above-mentioned anastomotic clip. The pulling clip 6 passes through the transparent cap 1 of the carrier from the forceps hole of the endoscope 8, and pulls the diseased tissue 7, so that the diseased tissue 7 moves toward the carrier. The transparent cap 1 approaches or enters the transparent cap 1 of the carrier.

[0052] In Example 1, only the anastomotic clip is used to clamp the diseased tissue 7, which is mainly suitable for tissues with better elasticity. At this time, the tissue can be sucked into the clamp 2 by relying on negative pressure. It will be hardened. At this time, it is difficult to suck the diseased tissue 7 into the clamp 2 by relying on the negative pressure alone, or the thickness of the clamped diseased tissue 7 is small, resulting in incomplete suturing of the diseased tissue 7. In this embodiment, the pull...

Embodiment 3

[0061] Embodiment 3, an anastomosis suit, is especially suitable for suturing large-area perforation 4 . In Example 2, when the traction clip 6 fails to grasp the appropriate diseased tissue 7, it will lead to the failure of the anastomotic clip to grasp the tissue, especially when the area of ​​the perforation 4 is large, due to the peristalsis of the stomach, the activity of the diseased tissue 7 is more Strong, bring difficulties to the grasping work, such as Figure 12 and Figure 13 As shown, in this embodiment, on the basis of Embodiment 2, a set screw 605 is added. The front end of the set screw 605 is provided with a threaded cone head 6051, and the center of the cable liner 603 is provided with an axial through cavity, that is, the cable liner The tube 603 is a hollow structure, and the positioning screw 605 is arranged in the axially through cavity, and can perform axial reciprocating movement relative to the cable liner 603 . The relative movement between the set ...

Abstract

The invention discloses an anastomosis clamp and an anastomosis set containing the anastomosis clamp. The anastomosis clamp comprises a carrier transparent cap, a pushing rod and a fixing clamp, wherein the carrier transparent cap is arranged at the front end of an endoscope; the front end of the carrier transparent cap is provided with a fixing clamp containing cavity, and the rear end of the carrier transparent cap is provided with a pushing cavity; the pushing cavity is communicated with the fixing clamp containing cavity; the fixing clamp is arranged in the fixing clamp containing cavity;one end of the pushing rod extends into the pushing cavity; the pushing cavity is located outside the endoscope; when the pushing rod is pushed forwards, the fixing clamp stretches out of the fixing clamp containing cavity, and the front end of the fixing clamp is tightened in the direction of the center axis. The anastomosis set comprises a traction clamp and the above anastomosis clamp, and thetraction clamp pulls the lesion tissues, so that the lesion tissues get close to the carrier transparent cap or enter the carrier transparent cap. The device is simple in structure, is not affected byhuman tissue peristalsis after entering a human body, cannot generate structural deformation and winding phenomena, and improves the success rate of an operation.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an anastomotic clip and an anastomotic suit containing the anastomotic clip. Background technique [0002] The OTSC anastomotic clip system is a combination of the OTSC anastomotic clip made of superelastic shape memory alloy and a soft endoscope. It is used for the compression and closure of the digestive tract tissue and can also be used to mark the wound. The OTSC anastomotic clip system is because of its good elasticity. , strong tightening force, more grasping tissues, and large scope, etc., are widely used in the medical field, but the OTSC anastomotic clip system in the prior art has the following disadvantages: [0003] (1) The structure is complex and inconvenient to use. It is necessary to pass the traction rope through the OTSC handwheel and bind it before operating the OTSC handwheel to clamp the tissue. [0004] (2) The operation level of the operator is high. If t...
