Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model aims at providing a blood vessel sheath pipe for preventing blood vessel pedicle of a muscle card is pressed to solve the problem that prior art exists, make the blood vessel in the back that coincide, effectively protect the blood vessel, prevent that the blood vessel from receiving the card of surrounding tissue and pressing and the blood vessel appears twisting round etc. thereby avoid causing flap necrosis, thrombus scheduling problem.
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1-3, the present embodiment provides a sheath for preventing a pedicle of a blood vessel from being jammed, which is configured to be sleeved on an outer wall of a blood vessel to be anastomosed when performing a blood vessel anastomosis operation, and includes an axially stretchable sheath body 1, the sheath body 1 is a tubular structure with openings at two ends, a grid 2 capable of deforming under a stress state is disposed on the sheath body 1, when the sheath body 1 is stressed axially, the sheath body 1 can be elongated, and an axis of the sheath body 1 can form different curvatures along with different deformation amounts of the grid 2 located at two sides of the axis, so as to better conform to the trend of the blood vessel to be curved; sleeving a blood vessel sheath on the outer wall of a blood vessel before vascular anastomosis is performed, and stretching the blood vessel sheath to a proper length to protect the blood vessel after vascular anastomosis at two ends is finished; a section of blood vessel sheath can be sleeved on the blood vessel, and after the anastomosis of the blood vessel is finished, the blood vessel sheath is stretched to uniformly cover the blood vessels on two sides of the anastomosis position; or sleeving the two sections of blood vessels to be anastomosed with the sheath vessels, and stretching the two sections of the sheath vessels respectively after the anastomosis of the blood vessels is finished so as to cover the blood vessels on the two sides of the anastomotic part respectively, thereby supporting the tissues around the blood vessels, preventing the surrounding tissues from clamping and pressing the blood vessels, effectively protecting the blood vessels by the sheath vessels, and avoiding the problems of flap necrosis, thrombus and the like caused by clamping and pressing, twisting and the like of the blood vessels.
In this embodiment, the sheath body 1 may be made of an absorbable material having a certain strength or a medical grade non-absorbable material, and when the non-absorbable material is selected, a material that is commonly used in medicine, can be used in a human body, and does not cause a side effect on the human body, such as a titanium or titanium alloy material, may be used; the sheath body 1 in the embodiment is preferably made of an absorbable material, the blood vessel sheath protects the blood vessel within a period of time after the operation, and after the patient recovers, the blood vessel sheath can complete the function and be absorbed by the human body, so that inconvenience and side effects on the human body can be avoided.
Further, the shape of the grid 2 is preferably a diamond shape or a hexagon shape, and the diamond shape or the hexagon shape is easier to deform, so that the sheath tube of the blood vessel is well stretched, and the blood vessel is protected to the maximum extent.
Further, both ends opening part and 2 departments of net of sheath pipe body 1 all are provided with the fillet to prevent that sharp-pointed structure from causing the damage to the vascular wall.
When carrying out the operation, it is 1-3mm that needs anastomotic blood vessel diameter mostly, the utility model discloses set up sheath pipe body 1's original diameter into 2mm-4mm, after tensile, sheath pipe body 1's diameter can correspondingly reduce, reduces to just in time approximately equal with the blood vessel diameter, neither has very big clearance between messenger's blood vessel sheath pipe and the blood vessel, causes the relative rocking between blood vessel and the blood vessel sheath pipe, can not extrude the blood vessel again to make blood vessel sheath pipe form fine protection to the blood vessel.
The original length of the sheath tube body is 5mm-10mm, the axial size is small, the sheath tube body can be conveniently sleeved into a blood vessel, and after the anastomosis of the blood vessel is finished, the sheath tube body is stretched to a proper length.
It should be noted that, as is obvious to a person skilled in the art, the invention is not limited to details of the above-described exemplary embodiments, but can be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
