Preferably, the shape of the second urging portion 520 is a rectangle with a circular chamfer. In other embodiments, other shapes of the second urging portion 520 may also be selected.

In order to facilitate the application of a force to separate the bottom plate from the positioning film, at least one edge of the bottom plate may have a first force applying portion 510 extending outward. In the present embodiment, one of the edges of the bottom plate has a first urging portion 510 that extends outward. Preferably, the shape of the first urging portion 510 is a rectangle with a circular chamfer. In other embodiments, other shapes of the first force applying portion 510 may also be selected.

In one embodiment, the top plate and the bottom plate may each have a force applying portion, or one of them may have such a force applying portion.

When the size and size of the bottom plate and the positioning film are completely the same, the separation of the bottom plate and the positioning film may be difficult. The first urging portion 510 is a portion that is connected to the bottom plate and is not bonded to the positioning film, and is more easily held by the hand or the tool, so that it is easier to find a point of application on the bottom plate, and the bottom plate and the positioning film are more easily separated by human. The second urging portion 520 has a similar effect as the first urging portion 510.

In summary, the disposable surgical positioning film provided by the embodiment of the present application has the advantages of good skin bonding effect, accurate positioning, protection of surgical incision, simple structure, simple positioning operation, and positioning at any time.

The disposable surgical positioning film package provided by the embodiment of the present application performs aseptic packaging on the disposable surgical positioning film to avoid contamination of the positioning film caused by pollution sources or misoperations in the storage process of the disposable surgical positioning film. Good conditions, safer use and easy storage for long periods of time.

The above description is only for the preferred embodiment of the present application, and is not intended to limit the present application, and various changes and modifications may be made to the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application are intended to be included within the scope of the present application.

Industrial applicability

The disposable surgical positioning film provided by the embodiment of the present application can realize the positioning operation by the illumination of the C-arm X-ray machine or the like. Since the soft coordinate developing layer is flexible and can be bent at will, the positioning film can be adhered to the surface of any surgical skin by the adhesive layer at random, so that the positioning film completely and stably adheres to the skin surface. During the positioning operation, the positioning film is closely attached to the skin surface of the operation area and can be positioned by the C-arm X-ray machine, etc., and can be removed after positioning, aseptic packaging, disposable use, without pre-operative preparation for high temperature and high pressure sterilization. Avoid cross infection and easy to operate. The positioning film can allow the scalpel and other surgical devices to be cut or passed through, and can be attached to the skin surface of the operation area for pre-operative and intraoperative positioning, which can meet the needs of the positioning at any time during the operation. At the same time, the positioning film can be located at the same time. It is always applied around the wound during surgery to protect the wound. The disposable surgical positioning film package provided by the embodiment of the present application is aseptically packaged in the aseptic packaging casing to prevent the disposable surgical positioning film from infecting bacteria before use, thereby being more sanitary and convenient to use.
