The invention has simple operation, can fully expose the endothelium of the blood vessel to be anastomosed and provides favorable conditions for subsequent anastomosis operation. The device can effectively reduce the difficulty of blood vessel anastomosis and bring convenience to the fields of organ transplantation and the like.
Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to an auxiliary device suitable for exposing vascular endothelium.
Background
Vascular anastomosis may be applied to a variety of surgical fields, such as organ transplantation, maxillofacial reconstruction, wound healing, and the like. In the manual anastomosis of blood vessels in liver transplantation operation or shunt operation of portal hypertension, the anastomosis time of each vena cava anastomosis opening is generally 10-15 min even for a trained doctor. After the portal vein is opened, the hepatic artery is anastomosed again for about 10min, which can cause the secondary thermal ischemia of the liver and biliary tract, and is the important reason for the high biliary tract complication after liver transplantation. The shorter the hepatic absence period in liver transplantation, the more stable the hemodynamics and the faster the recovery of the hepatic function. In order to improve the quality and speed of anastomosis and reduce the difficulty of anastomosis and postoperative complications, people have made continuous improvements and attempts on the quality of anastomosis and suture lines, but still are based on the traditional manual suture technology, and cannot avoid the influence of surgical skills and suture lines on the healing of an anastomosis. There are also attempts to anastomose blood vessels in a non-suture manner, but the difficulty is how to fully expose the vascular endothelium and achieve the anastomosis of the vascular endothelium to the endothelium, so far, no new technology can replace manual suture.
Disclosure of Invention
In order to overcome the drawbacks of the prior art, the present invention provides an auxiliary device for exposing the vascular endothelium, which is simple to operate, can fully expose the vascular endothelium to be anastomosed, and provides advantages for the subsequent anastomosis operation. The device can effectively reduce the difficulty of blood vessel anastomosis and bring convenience to the fields of organ transplantation and the like.
In order to achieve the purpose, the invention adopts the technical scheme that:
an auxiliary device suitable for exposing the vascular endothelium comprises a circular or elliptical auxiliary device sheet 1, the inner diameter of the auxiliary device sheet is matched with the corresponding vascular lumen, a plurality of small holes 2 are formed in the auxiliary device sheet 1 along the circumferential direction, the aperture of each small hole 2 is matched with a suture needle with a thread, and the suture needle with the thread penetrates through the vascular endothelium to be fixed.
The number of the small holes 2 is 6 to 8, and the small holes are uniformly distributed in the circumferential direction.
The auxiliary device sheet 1 has a thickness of about 1mm and the small holes 2 have a diameter of 0.5-1 mm.
The auxiliary device sheet 1 is made of a high polymer material, and the surface of the auxiliary device sheet is subjected to plating treatment such as titanium nitride, polytetrafluoroethylene and parylene.
Compared with the prior art, the auxiliary device can fully expose the endothelium of the blood vessel to be anastomosed, and provides favorable conditions for subsequent anastomosis operation. The blood vessel anastomosis can be completed by various ways such as magnetic ring suction, glue bonding and the like. After the operation is finished, the auxiliary device can be cut and removed through the surgical knife blade so as to be not left in the body. The device is simple and convenient to use, and the vascular endothelium is fully and reliably exposed. The vascular endothelium is exposed through the device, and vascular anastomosis is realized subsequently and by utilizing a novel anastomosis technology, so that the overlong liver-free period and a series of associated complications caused by manual suturing in a liver transplantation operation are avoided.
Drawings
FIG. 1 is a schematic diagram of the present invention.
Detailed Description
The embodiments of the present invention will be described in detail below with reference to the drawings and examples.
As shown in figure 1, the auxiliary device suitable for exposing the vascular endothelium comprises a circular or elliptical ring-shaped auxiliary device sheet 1, the thickness of the auxiliary device sheet is about 1mm, the inner diameter of the auxiliary device sheet is matched with the corresponding vascular lumen, a plurality of axial small holes 2 are uniformly formed in the auxiliary device sheet 1 along the circumferential direction, the number of the small holes 2 is 6-8 in the embodiment, the hole diameter of the small holes is matched with that of a suture needle with a thread and is about 0.5-1mm, and the suture needle with the thread penetrates through the vascular endothelium to be fixed. The device adopts high polymer material, and the surface is subjected to plating treatment such as titanium nitride, polytetrafluoroethylene, parylene and the like.
In the using process, a blood vessel to be anastomosed penetrates into the inner ring of the auxiliary device sheet 1, the auxiliary device sheet 1 is sleeved at the broken end of the blood vessel to be anastomosed, and then a suture needle with a thread penetrates through the small hole 2 to fix the inner skin of the blood vessel. After all the small holes 2 are fixed, the vascular endothelium is fully exposed in a bell mouth shape, so that the subsequent operation is convenient.
