Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the utility model, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the utility model.

Referring to fig. 1 and 2, in the present embodiment, a protective anvil head device 1 for laparoscopic surgery is provided, where the protective anvil head device 1 for laparoscopic surgery includes: a leg part 11, wherein an insertion hole 111 extending along the length direction of the leg part 11 is arranged in the leg part; a head 12, wherein the head 12 is positioned at one end of the leg 11, and the head 12 is fixedly connected with the leg 11; the end surface of the head 12 far away from the leg 11 is an arc end surface.

As shown in fig. 3, the protective anvil head device 1 for laparoscopic surgery of the present invention can be used for protecting the center rod spike portion 2, and the center rod spike portion 2 can be inserted into the insertion hole 111 in the leg portion 11, so that the center rod spike portion 2 can be prevented from damaging organs in the abdominal cavity during the surgical operation; because the central rod spike part 2 is protected by the protective nail anvil head device 1 for the laparoscopic surgery, the use is safer, the operation is quicker, and the time and the labor are saved.

In one example, the head 12 may be a solid structure, and by providing the head 12 as a solid structure, the hardness of the head 12 may be relatively large, so that the head 12 is not easily deformed. Of course, in other examples, the head 12 may be a hollow structure or a shell structure.

Optionally, the shape of the head 12 may be set according to actual needs, and specifically, the shape of the head 12 may be a semi-oblate sphere.

As an example, the length of the insertion hole 111 is equal to the length of the central stem spike 2 to be protected; of course, in other examples, the length of the insertion hole 111 may be smaller than the length of the center rod spike 2.

Specifically, the inner diameter width of the insertion hole 111 is larger than the diameter width of the center rod spike 2 to ensure that the center rod spike 2 can be inserted into and fixed to the insertion hole 111.

In one example, the length of the insertion hole 111 may be smaller than the length of the leg portion 111; in another example, the length of the insertion hole 111 may be equal to the length of the leg portion 111.

As an example, the material of the leg portion 11 may be selected according to needs, and preferably, the material of the leg portion 11 may be plastic, rubber, or silicone, that is, the leg portion 11 may be a plastic leg portion, rubber, or silicone leg portion; the material of the head 12 can be selected according to actual needs, preferably, the material of the head 12 can be plastic, rubber or silica gel, that is, the head 12 can be a plastic head, rubber or silica gel head.

Alternatively, the leg 11 and the head 12 may be integrally connected; of course, in other examples, the leg 11 may be welded to the head 12; the leg 11 may also be screwed onto the head 12.

In an alternative example, continuing to refer to fig. 2, the arcuate end surface of the head 12 may be provided with a plurality of interconnected perforations 121; the nail anvil head protection device for the laparoscopic surgery further comprises a lead 13, and the lead 13 sequentially penetrates through at least two through holes 121. Through the through hole 121 on the arc end surface of the head 12 and the lead 13, the protective nail anvil head device 1 can be conveniently taken down from the central rod of the circular stapler after the central rod of the circular stapler protected by the protective nail anvil head device 1 is sent to a required position.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
