The headgear provided in the embodiment of the present disclosure, that is, the gamma knife positioning headgear, can be worn on the patient's head by setting the cap body 1, and then the head nail 2 can be used to offset the target position of the patient's head to achieve the patient's head lesions. Positioning. The head frame can be worn on the patient's head through the integrally formed cap body 1, which is functionally equivalent to the base ring and the vertical post in the prior art, which significantly simplifies the structure of the head frame, and only needs to nail the head nail 2 during application. Assembled on the cap body 1, simplifying the assembly process.

In the prior art, a screw hole provided on a base ring is used to connect with a U-shaped frame on a treatment bed through screws. In the wearing state, the base ring is located at the lower part of the patient's head. During the above connection, the shoulder of the human body will hinder the above connection, making the connection operation inconvenient. In order to solve the above technical problems, the head frame provided by the embodiment of the present disclosure further includes: a fixing body 3 located on the top and outer side of the cap body 1, and connecting the head frame with the treatment bed through the fixing body 3 to ensure the fixation of the head frame relative to the treatment bed By setting the fixed body 3 outside the top of the cap body 1, the installation space is significantly increased, and the connection between the head frame and the treatment bed is more convenient.

It can be understood that the cap body 1 is worn on the patient's head, and the head nail 2 is disposed along the radial direction of the cap body 1 to ensure that it can abut the target position of the skull of the patient. In order to prevent the patient's breathing from being hindered when worn, the bottom edge of the cap body 1 may be located above the nostril of the patient.

Wherein, the cap body 1 may be provided as a whole closed type, that is, the wall of the cap body 1 is closed; the cap body 1 may also be provided as a non-closed type, that is, the wall of the cap body 1 is open, with an opening on it. The hole area to expose part of the skull and reduce the weight of the cap 1.

Taking an open (ie, non-closed) cap body 1 as an example, as shown in FIG. 1 and FIG. 2, the cap body 1 may include a plurality of links 101, and the plurality of links 101 are cooperatively configured to receive A receiving cavity in the patient's head. Among them, a lateral gap is formed between two adjacent links 101 to serve as the above-mentioned opening area.

Considering that the receiving cavity of the cap body 1 is matched with the contour of the patient's head as much as possible, and the head frame is made as light as possible, the number of the connecting rods 101 may be 3-6, for example, 3, 4 and so on. The plurality of connecting rods 101 are evenly distributed at the same interval along the circumferential direction to strengthen the structure of the cap body 1 and at the same time give its aesthetic appearance.

It can be known from the above that the cap body 1 is equivalent to the base ring and the vertical pole in the prior art, and its structure is significantly simplified compared with the prior art. And when in use, only the head nail 2 and the connecting rod 101 need to be connected, and installation is more convenient.

In one example, the top ends of the plurality of links 101 meet and meet to form the top of the cap body 1, and the fixed body 3 is installed at the joint of the plurality of links 101.

The top ends of the plurality of connecting rods 101 are merged and connected to form a contact point or a contact surface, which is not only conducive to improving the strength of the cap body 1 but also facilitates the installation of the fixing body 3 thereon.
