Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.

As shown in fig. 1 to 3, in the embodiment of the present invention, the vein retractor for thyroscopic surgery is a detachable assembly structure, which can be detached into two parts, including a puncture retractor 1 and a novel vein retractor 2.

In the embodiment, the puncture retractor 1 of the vein retractor for the thyroscope surgery consists of a handle 11, a connecting rod 12 and a U-shaped hook needle 13, wherein the tail end of the U-shaped hook needle 13 is in a needle point shape, so that the skin can be conveniently punctured to enter the surgical field, one end of the connecting rod 12 is fixedly connected to the handle 11, the other end of the connecting rod 12 is connected with the U-shaped hook needle 13 and is of an integrated structure, the connecting part of the U-shaped hook needle 13 is reduced, and therefore the disinfection dead angle is reduced; preferably, the connecting rod 12 and the U-shaped crochet hook 13 of the venous draw hook for thyroscopic surgery in the embodiment are made of stainless steel; the shape of the novel vein drag hook 2 of the vein drag hook for the thyroscopic surgery is U-shaped, and the novel vein drag hook 2 is provided with the connecting part 21, so that the novel vein drag hook 2 can be sleeved and fixed at the needle head part of the U-shaped hook needle 13, and the hidden danger that the sharp needle head damages the blood vessel is effectively avoided.

As shown in fig. 4-5, the outer surface of the needle portion of the U-shaped bearded needle 13 is provided with a plurality of protrusions 14, and the surfaces of the protrusions are smooth and have no sharp edges, so as to prevent the muscle tissue and blood vessels from being damaged, the connecting part 21 of the novel vein retractor 2 is a tubular structure, and the inner part of the connecting part is provided with a groove 22 matched with the protrusions 14, so that the novel vein retractor 2 can be directly sleeved and fixed on the needle portion of the U-shaped bearded needle 13 through the connecting part 21.

It should be noted that the figures show 3 protrusions 14 and 3 grooves 22, and the number of the protrusions 14 and the grooves 22 can be increased or decreased according to the actual situation. In addition, in the above embodiments, the connection manner of the novel intravenous retractor 2 and the needle portion of the U-shaped crochet needle 13 is not particularly limited, and may be, for example, a combination of the protrusion 14 and the groove 22 in the embodiments, or other common connection manners in the prior art, such as a threaded connection, as long as it can simply and conveniently fix the novel intravenous retractor 2 to the needle portion of the U-shaped crochet needle 13.

In this embodiment, the use method of the venous retractor for the thyroscopic surgery in the thyroscopic surgery is as follows: send into the operation under the help of laparoscopic surgery pincers novel vein drag hook 2 by the laparoscopic tunnel, puncture drag hook 1 pierces through skin entering operation field from the extroversion to the introversion through neck skin, puncture drag hook 1 assembles fixedly with novel vein drag hook 2 through arch 14 and recess 22 in the operation field, the thyroid laparoscopic surgery who the equipment was accomplished pulls the blood vessel with the vein drag hook, adjust the position of the vein drag hook for the thyroid laparoscopic surgery as required, can carry out the split with puncture drag hook 1 and novel vein drag hook 2, with puncture drag hook 1 after the split withdraw from the operation field, it is fixed with novel vein drag hook 2 equipment that it gets into the operation field to puncture again as required position, after the operation, puncture drag hook 1 can be dismantled and withdraw from the operation field through former route separately with novel vein drag hook 2.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, all should be in the scope of protection of the present invention for the technical solution that the concept of the present invention can be obtained through logic analysis, reasoning or limited experiment based on the prior art.
