A system and method for knee arthroplasty procedures, using a novel leg rotation fixture to enable the leg mechanical axis, the tibia and the femur to be mutually disposed such that the load bearing, mechanical axis of the leg runs through the center of the knee joint. A measurement gauge is provided for mounting on the tibia and for aligning a baseplate in a known position on the tibia. This baseplate supports an X-ray target plate in a known position relative to the tibia, used in determining the mechanical axis, and an optional surgical robot, used to perform tibial and femoral cuts. The position of the femur relative to the robot may be determined from X-ray imaging of the pelvic region after attachment to the baseplate of an additional target extending to the pelvic region. The system enables improvement in the accuracy of knee arthroplasty procedures.

At least one elongated body is sized and configured for implantation in a desired orientation in a tissue region in an airway. An array of projections extends from the elongated body and is resiliently coupled to the elongated body. The array or projections is in a normally biased outward extending condition sized and configured to engage tissue and resist a reorientation of the elongated body within the tissue region out of the desired orientation after implantation of the elongated body in the tissue region. The array of projections is sized and configured to resiliently yield by flexing inward against the elongated body during implantation of the elongated body in the tissue region.

Embodiments of a smart surgical drape are disclosed. The surgical drape includes an insulating material and one or more sensors mounted with the insulating material, the one or more sensors detecting proximity between the surgical drape and a device.

The present invention provides a therapeutic limb covering and an associated method of treating chronic swelling of a limb. The limb covering is uses hydrostatic pressure provided by liquid contained within the covering to apply pressure to the limb. The limb covering comprises a substantially non-distensible flexible outer layer, a distensible flexible inner layer joined together and a liquid tight bladder therebetween. The covering may be adapted for releasable securement about a limb such as an arm or a lower leg and foot of a patient. After placement on the limb, when the bladder is filled with a liquid, such as water, it expands to contact and apply pressure to the limb.

A protective helmet apparatus of modular construction to be worn by anesthetized patients for facial support during surgery. The helmet apparatus is assembled using one of a plurality of interchangeable, substantially transparent helmet casings, which are removably attachable to a plurality of dismountable facial cushions providing even support to the facial surface of a patient. The removable facial cushions are dimensioned on and interior surface to accommodate different sized facial structures of different patients to yield maximum pressure diffusion on the face and chin of the patient and are replaceable when worn. The exterior surface of the facial cushions are dimensioned for cooperative engagement with the interior surface of the helmet casing. A plurality of different facial cushions and helmet casings are modular in design and dimension to be interchangeable with each other thus providing accommodate the broad differences in facial structure and size of patients using them for surgery. The cushions may be marked with printed or color coded indicia to designate size. A view of the patients eyes and surrounding area is afforded through in line ocular apertures extending around a front surface area and up at least one sidewall. The ocular aperture is in line with a cushion ocular aperture when the cushion is engaged with the casing thereby allowing a view of the patent eye and surrounding face through the ocular aperture from the side of the device. Additional utility is provided by variable elevation above a registered engagement with a mount which also may provide a mirrored surface to reflect the patent facial features for viewing by upright doctors and operating staff. An optional integral heating element aids in temperature control of the patient's head during surgery.

The invention comprises a laying, semi-vertical, or seated patient positioning, alignment, and/or control method and apparatus used in conjunction with multi-axis charged particle or proton beam radiation therapy of cancerous tumors. Patient positioning constraints are used to maintain the patient in a treatment position, including one or more of: a seat support, a back support, a head support, an arm support, a knee support, and a foot support. One or more of the positioning constraints are movable and/or under computer control for rapid positioning and/or immobilization of the patient. The system optionally uses an X-ray beam that lies in substantially the same path as a proton beam path of a particle beam cancer therapy system. The generated image is usable for: fine tuning body alignment relative to the proton beam path, to control the proton beam path to accurately and precisely target the tumor, and/or in system verification and validation.

An operation support device having a surgical instrument unit and a surgical instrument unit support section, includes: an intermediate member connected to the surgical instrument support section and configured to hold the surgical instrument unit; a shielding member having a hole portion engaged with the intermediate member; and a driving force supply unit installed at the surgical instrument support section. A first space and a second space are formed by an assembly constituted by the shielding member and the intermediate member engaged with the hole portion as a boundary. The intermediate member is connected to the surgical instrument support section at a side of the first space, and holds the surgical instrument unit at a side of the second space. The driving force supply unit and the surgical instrument support section are disposed in the first space.
