Abstract
The invention provides a proximal anastomosis device, and belongs to the technical field of surgical medical supplies. A lower part of a hemispherical body is provided with a circular bottom edge, the middle part of the hemispherical body is provided with a connecting shaft, the bottom edge of the hemispherical body is in circle shape, the diameter R of the circle is 16 mm, the hemispherical body is a hemisphere with a diameter A of 16 mm, the hemispherical body is formed by latticed body wires, and the latticed body wires are gathered and fixed at one point on the top end of the hemispherical body and connected with the connecting shaft. The proximal anastomosis device has the advantages that leakage from blood flow anastomosis stoma of aorta ascendens is prevented, a proximal end of saphenous vein bypass grafts is convenient to suture, and inner wall peeling of aorta ascendens caused by use of a side wall clamp is prevented. A memory function is provided by the proximal anastomosis device, so that after the proximal saphenous vein bypass graft is sutured in a surgery, the device can be taken out through catheters with diameters of 3.5 mm, 3.8 mm, 4.0 mm, 4.3 mm and 4.5 mm, and can be recovered to the original state for suturing the next proximal anastomosis stoma. The device can be reused in the same surgery of the same patient.
Description
Technical field
The present invention relates to a kind of proximal anastomosis device, belong to surgical articles for use technical field.
Background technology
Coronary artery bypass grafting is the conventional operation for the treatment of coronary artery disease.This operation uses the vein or arteries that take off in chest, leg or arm, proximal anastomosis is at ascending aorta, far-end strides across the coronary artery of stenosis or occlusion, to improve the blood supply of heart and to reduce the generation of cardiovascular event, thus improves patients ' life quality and life-saving.Because Coronary Artery Bypass Grafting blood vessel proximal anastomosis mouth is directly sutured on ascending aorta, when conventional bypass graft sews up proximal anastomosis mouth, need to use sidewall clamp closing part to divide ascending aorta, block anastomotic stoma blood flow, and sew up near-end bridge blood vessel, but when sidewall clamp closes or decontrols ascending aorta, ascending aorta inner membrance and atheromatous plaque can be caused to come off, blood vessel wall is impaired, easily cause Thrombosis, and then cause cerebral infarction, and distal artery blood vessel embolism, the particularly patient of ascending aorta calcification, more easily cause above-mentioned complication, proximal anastomosis mouth is even caused to sew up.Not yet find good solution clinically at present.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the object of this invention is to provide a kind of proximal anastomosis device, it has can avoid using sidewall clamp to close ascending aorta, reduces the situation that calcification ascending aorta inwall peels off, thus reduces the feature of operation risk.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of proximal anastomosis device, the bottom of hemispherical body has base, centre and has connecting axle, and base is rounded, and circular diameter R is 16mm; Hemispherical body is hemispherical, and diameter A is 16mm; Hemispherical body is latticed body silk material composition, and body silk material comes together on the top of hemispherical body and is fixed on a bit, and is connected to connecting axle.
The present invention is advantageously:
1, the situation stopping ascending aorta blood flow self-fitting mouth seepage is played in art, convenient stitching bridge blood vessel near-end, close without sidewall clamp and just can complete coincideing of ascending aorta near-end stapling mouth, significantly decrease because ascending aorta folder closes the such as cerebral infarction caused, the complication such as limb artery embolization.
2, this proximal anastomosis device is formed by the silk material braiding with memory function, like this, this device can be taken out by the conduit that diameter is 3.5mm, 3.8mm, 4.0mm, 4.3mm, 4.5mm after sewing up near-end bridge blood vessel in art, and restore to the original state, sew up for next proximal anastomosis mouth.
3, base loop buffer pad, is conducive to protecting the sealing around the injury-free and anastomotic stoma of ascending aorta wall, prevents seepage.
4, for same patient, this device can be reused, i.e. same of same patient operation, uses a set of device can complete the stitching of all anastomotic stoma, reduce expense.
Device of the present invention takes the silk material of the nitinol with good shape memory function to weave.This alloy is after thermoforming process process, and shape memory strengthens further.Namely this bracing or strutting arrangement not only has certain intensity, can overcome aortic pressure, thus avoids the obturation of anastomotic stoma;
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the perspective view of the embodiment of the present invention;
The schematic top plan view of Fig. 2 embodiment of the present invention.
Detailed description of the invention
The following stated is only preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, as Figure 1-Figure 2, described proximal anastomosis device comprises hemispherical body 1, the bottom of hemispherical body 1 has base 4, centre has connecting axle 2, and base 4 is rounded, and circular diameter R is R=16mm, hemispherical body 1 is hemispherical, and diameter A is A=16mm.
Body silk material 3 braiding that described hemispherical body 1 is prepared by nitinol forms, the external diameter of body silk material 3 is 0.15mm, and is in unidirectional body silk material 3 and is parallel to each other, and assumes diamond in shape between the body silk material 3 of different directions, meanwhile, radially scatter from body top to base.
By the high resiliency thin film coated of liquid state in hemispherical body 1 surface, liquid high resiliency thin film can use medical polyurethane, politef etc.
The thin film 5 that described hemispherical body 1 external application highly elastic material is made, in the middle of body silk material sandwiches by thin film 5, thin film 5 is airtight film, and blood can not penetrate, thin film 5 thickness 0.2mm, and base thin film 5 is annular, thin film ring diameter 0.3mm.
Described body silk material comes together on top and is fixed on a bit, and is connected to connecting axle 2, and connecting axle 2 is one cylindrical, and body diameter 1mm, there is screw thread connecting axle 2 inside.
The thermoforming process process of nitinol belongs to prior art, repeats no more.
