Problems solved by technology

However, these small orifices can be difficult to seal, especially if the sealing location is inside the patient's body
At present, manual purse-string suture is usually used to close these wounds clinically. However, this kind of suture has high requirements for doctors, requires a long learning curve, and takes a long time to suture, and requires a large chest opening to enter the suturing equipment.

Embodiment 1

[0038] The apex closer of the embodiment of the present invention includes a main structure, a fixing structure and an outer tube. Please refer to figure 1 and figure 2 , the main structure includes at least two anchoring pieces 1, generally preferably 2 to 9, and this embodiment takes 5 as an example. The anchor 1 includes a main body section 11 connected to each other and a curved end 12. The main body section 11 is connected to each other to form an annular structure 2 with an opening. In the operation of interventional surgery, the curved end 12 bends toward the annular structure 2 in a natural state, and the myocardial tissue is very fragile, so the whole device must be fixed by the curved anchor 1 like a barb.

[0039] The fixing structure is arranged at the opening end of the ring structure 2 , and after the interventional operation, the fixing structure closes the opening 21 of the ring structure 2 , thereby closing the opening of the apex of the heart. In this emb...

Embodiment 2

[0050] Compared with the first embodiment, the present embodiment differs only in the fixing structure.

[0051] Please refer to Figure 8 , the fixing structure of this embodiment includes a second fixing ring 81 and a second fixing needle 82, the second fixing ring 81 and the second fixing needle 82 are respectively connected to the two ends of the opening 21 of the annular structure, when the opening of the apex of the heart is to be closed, the The second fixing pin 82 is directly inserted into the second fixing ring 81, and the shape of the second fixing ring 81 is also not required, and may be circular, elliptical or polygonal.

[0052] In the following, the structure and cooperation relationship of each component will be introduced in combination with the specific use method of each component in the operation.

[0053] (1) Insert the outer tube of the apical closer into the apical tissue for fixation;

[0054] (2) The anchor piece of the apical closer is inserted into...

Abstract

The invention discloses a cardiac apex sealer. The cardiac apex sealer comprises a main body structure, the main body structure comprises at least two anchoring parts, each anchoring part comprises amain body section and a bent tail end which are connected with each other, the main body sections are connected with each other to form an annular structure with an opening in a surrounding mode, theannular structure provides a channel for an interventional operation, and the bent tail ends are bent towards the annular structure in a natural state; a fixing structure is arranged at the open end of the annular structure, and after the interventional operation is finished, the fixing structure seals the opening of the annular structure, so that the cardiac apex opening is sealed; an outer sleeve is matched with the anchoring part for use, the outer sleeve is provided with a tip end, the tip end is fixed to cardiac apex tissue in the using process, and the anchoring part penetrates through the outer sleeve to enter the cardiac apex tissue and be fixed. The cardiac apex sealer is simple in structure and easy to operate, the operation efficiency is greatly improved, and the cardiac apex sealer is made of common medical materials at present and is easy to research, develop and produce.

Description

technical field [0001] The invention relates to a medical tissue sealing device, in particular to a heart apex sealing device. Background technique [0002] Surgical intervention requires gaining access to viscerally damaged or diseased surgical sites, such as perforating or cutting holes in healthy tissue layers to gain access. Surgical instruments can be inserted through a cannula or retractor to gain access to the surgical site, a procedure that requires the surgeon to enter the myocardial entrance to the patient's heart through a small intercostal incision in the patient's chest, in addition to cutting open the heart Myocardium to form a passage opening, and an introducer sheath is inserted to maintain the desired diameter of the passage opening, followed by protection of cardiac tissue during insertion or removal of catheters and other implements through the sheath. Catheters and other instruments may then be inserted through the cannula and into one or more chambers o...
