An amount of radiation exposure of a medical staff is significantly reduced, and a large working area is ensured during an operation. A size of each component of a radiation protection equipment is reduced so as to decrease a weight thereof. The radiation protection equipment is provided, which can be installed within a short time period before an operation and easily put away after the operation. The radiation protection equipment, includes: a first protection sheet arranged on a periphery of a radiation source device and configured to shield radiation; a second protection sheet formed separately from the first protection sheet, arranged on a side of an operation table, and configured to shield radiation; and a third protection sheet formed separately from the first and second protection sheets, arranged on a periphery of a surgical field so as to expose the surgical field, and configured to shield the radiation.

The present invention relates to a low-temperature treatment device capable of preventing nerve damage. The low-temperature treatment device according to one embodiment of the present invention can comprise: a cooling pocket which is inserted and positioned in a rectum and which has a predetermined shape during expansion; and a circulation tube which has a passage through which fluid flows in and out and which is inserted into the cooling pocket so as to circulate the fluid in an inner space of the cooling pocket.

A removable tip for a light energy handpiece comprises a hollow conduit configured to surround a light guide in the handpiece; a support extension having a length longer than a length of the hollow conduit; and a shielding extension coupled to the support extension at an angle less than 180 degrees and located in front of the hollow conduit. The shielding extension is configured to be inserted behind an eyelid and extend to the fornix, the shielding extension comprised of a thermally insulative material.

The present disclosure provides a positioning assembly for a radiation irradiation system. The positioning assembly includes a shielding body made of polymer and radiation shielding material capable of shielding the radiation and a sealing bag for accommodating the shielding body, when the target to be irradiated is placed on the positioning assembly, the positioning assembly is recessed with a shape of the target at the position where the target is placed and forms a contour corresponding to the target to position the target to be irradiated.

An X-ray system is described with a scatter radiation shielding device to be mounted underneath an operating table. The shielding device (10) comprises one or more layers of a radiation blocking material (6) and a cut-out (8) in the one or more layers. The cut-out extends from a point in or near a center of the one or more layers towards an edge to allow radiation transmission to pass. The shielding device is rotatable around a rotation axis. The shielding device substantially reduces the scatter radiation originating from the patient.

In some aspects, the present disclosure pertains to hydrogel-securing structures that comprise anchoring element that is configured to anchor the structure to bodily tissue and a hydrogel-retaining element that is configured to retain a hydrogel mass. Other aspects of the present disclosure include kits that contain such hydrogel-securing structures. Other aspects of the present disclosure pertain to methods that comprise (a) delivering a structure that comprises a hydrogel-retaining element in a body of a subject comprising first and second tissues, such that the hydrogel-retaining element may be disposed between the first tissue of tissue and the second tissue and (b) delivering a hydrogel to the structure, such that the hydrogel is loaded onto and/or into the hydrogel-retaining element and retained in place by the hydrogel-retaining element, and such that the hydrogel is disposed between the first and second tissues thereby separating the first tissue from the second tissue.
