Problems solved by technology

[0005] 2. Deep suturing device, which is similar to the principle of sewing. The mechanical structure is complex and precise. The whole operation process is cumbersome. It is necessary to judge the position of the blood vessel, and then suture the needle, tie a knot, and cut the thread
[0007] The common problems of these measures are: the structure and operation are complicated, the users need to be trained, and it may also cause a large amount of foreign bodies in the cavity to cause other complications

Embodiment 1

[0032] Such as Figure 1~5 As shown, a human pathological or iatrogenic cavity closure device includes a sheath tube 6 and a push rod 1. The front end of the push rod 1 is connected with an elastic anchor hook 2, and the elastic anchor hook 2 includes an anchor connected to the front end of the push rod 1. Seat 5 and three elastic puncture arms 3 arranged at equal intervals connected to anchor seat 5 , the tail ends of the puncture arms 3 are acupuncture portions 31 . Barbs 4 are provided on the outer surface of the puncture arm 3 .

[0033] The elastic anchor hook 2 is pressed together and placed in the sheath tube 6 together with the pushing rod 1 . After the elastic anchor hook 2 is disengaged from the sheath tube 3, the puncture arm 3 springs back to form a claw-shaped anchor hook.

[0034] The push rod 1 and the elastic anchor hook 2 are made of materials that can be absorbed by the human body.

[0035] The elastic anchor hook 2 is pressed together in advance and place...

Embodiment 2

[0037] Such as Figure 6~7 As shown, repeat Example 1, the difference is: the push rod 1 is set to be a detachable push rod, and a release device 8 is provided between the push rod 1 and the anchor seat 5, and the release device 8 is an electric release device or Mechanical release device.

[0038] During operation, the cavity is closed when the tissue is completely collected on the anchoring seat 5; finally, it is released and withdrawn from the push rod 1 to complete the operation.

Abstract

The invention discloses a human pathological or iatrogenic cavity blocking device. The device comprises a sheathing canal and a push rod, wherein an elastic anchor is connected to the front end of the push rod and comprises an anchoring base connected with the front end of the push rod, and a plurality of elastic puncturing arms connected with the anchoring base, and an acupuncturing part is arranged at the tail end of each acupuncturing arm; the elastic anchor is compressed and placed in the sheathing canal together with the push rod, and after the elastic anchor disengages from the sheathing canal, the puncturing arms rebound off to form claw-shaped anchors. The device is operated in the same way as ordinary instruments in cavities and has the advantages that operation is easy, the blocking effect is good, and the number of residues in a cavity is small.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for closing human pathology or iatrogenic cavities. Background technique [0002] In the puncture operation, the wall of the blood vessel will be punctured, and at the end of the operation, it is necessary to close some kind of pathological cavity or the cavity generated by the medical treatment itself. Such as various atrial and ventricular wall defects; endoscopic surgery and endovascular interventional surgery to establish a channel from the outside to the body. [0003] Currently available closure methods are: [0004] 1. A occluding device with a dumbbell-shaped structure. After the device penetrates into the blood vessel, it can expand to form a plug with a diameter larger than the diameter of the blood vessel cavity, and then drag the plug back to block the blood vessel cavity. [0005] 2. Deep suturing device, which is similar to the princip...
