Embodiment

[0028] 80 parts of barium sulfate with a purity of 96-99% and 20 parts of plastic particles are put into a container, and then the container is heated to 180 degrees Celsius to melt the barium sulfate and the plastic particles and stir evenly. Finally, the melted material is molded into a film blank with a thickness of 0.8 mm. Carve the film blank to form a radiation positioning film; the radiation positioning film is sequentially subjected to gluing, filming, packaging, and sterilization processes to become a usable finished product.

[0029] The film solves the corresponding problem of the deep tissue in the body and the projection on the body surface, so that the projection can be expressed in the form of coordinates, and is widely used in orthopedic operations such as the positioning of the vertebral body in vertebroplasty, the measurement of the length of the fracture line of the external fixation bracket, and the extraction of the femur. Positioning of screws by nailing;...

Abstract

The invention relates to the field of ray positioning films, and in particular relates to a ray positioning film and a preparation method of the ray positioning film. The ray positioning film is prepared from the following components in parts by volume: 40-90 parts of barium sulfate, and 10-40 parts of plastic particles. The ray positioning film has the beneficial effects that the ray positioningfilm is used in the pleural effusion puncture and drainage surgery, according to a radiograph picture, the part and range allowing for puncturing can be marked and shown through coordinates of the product, so that the puncture range is more accurate, and the use convenience is also increased. Meanwhile, the novel puncture mode gets rid of the dependence on anatomic landmarks, is particularly suitable for obesity patients and patients with body surface anatomic variation, and belongs to the novel method different from that taught in textbooks, so that the occurrence of injuries is effectively prevented. When the ray positioning film is used in the vertebral plasty, during one time or two times of radiograph of a C-arm machine for a patient, the surgery needle inlet path of the patient can be marked, thus the irradiation times and surgery time are greatly reduced, and the radiant quantity to a doctor and the patient is reduced. The radiograph times is reduced to 1-2 times from 7-8 times,and the radiograph time is shortened to 5-10 min from 30-40 min. The ray positioning film has very good social benefit and clinic use value.

Description

technical field [0001] The invention relates to the field of radiation positioning films, in particular to radiation positioning films and a preparation method thereof. Background technique [0002] X-ray films are required before puncture and drainage of pleural effusion to determine the scope and volume of pleural effusion. Then puncture according to the corresponding anatomical positioning. When using this method, puncture may easily lead to organ damage in obese patients or patients with unclear anatomical landmarks. [0003] In vertebroplasty, the traditional method is to place Kirschner wires on the patient's body surface, and after several shots, determine the positional relationship between the Kirschner wires and the vertebral body, so as to find the needle insertion route for the operation. This process is generally It takes 7-8 times and the time is 30-40 minutes. Contents of the invention [0004] The technical problem to be solved by the present invention i...
