A minimally invasive retractor system is shown which has a support frame having two opposing pairs of horizontally oriented sides. The sides of the frame can be adjusted to vary an interior space of the frame. Four retractor blades are mounted on the frame for engaging tissue within a surgical site. Each retractor blade has an elongate body portion with a length which is oriented perpendicularly to the frame in use. One of the retractor blades can be equipped with a light source and a suction source which are integral to the blade. The blade also has an integral power source for powering the light source. The blade can also house a tissue retractor such as a dural retractor for retracting the dural sack of a patient during spinal surgery.

A system and method for tomographic image reconstruction using truncated limited-angle projection data that allows exact interior reconstruction (interior tomography) of a region of interest (ROI) based on the linear attenuation coefficient distribution of a subregion within the ROI, thereby improving image quality while reducing radiation dosage. In addition, the method includes parallel interior tomography using multiple sources beamed at multiple angles through an ROI and that enables higher temporal resolution.

A computer assisted surgical system that includes an apparatus (110) for imaging a region of interest of a portion of an anatomy of a subject; a memory containing executable instructions; and a processor programmed using the instructions to receive two or more two-dimensional images of the region of interest taken at different angles from the apparatus and process the two or more two-dimensional images to produce three dimensional information associated with the region of interest.

A laser induced liquid jet generating device comprising: a main body 6 adapted to be filled with a specified laser beam absorbing liquid and configured such that it can contain a laser irradiating part 4 of an optical fiber from which laser beams are emitted to generate jet streams J of said liquid W by irradiating said liquid W with laser beams, with said jet streams J ejected from said main body 6 to the outside; said main body 6 comprising: a catheter mounting unit mounted integrally or in a removable manner on a catheter member 13 into which said jet stream J is introduced; a jet generating tube unit 10 in which said laser irradiation part 4 is adapted to be positioned; and a heat transfer inhibition means 11 for inhibiting thermal effect due to laser beams irradiated by said laser irradiating part 4 from being transferred outside through said jet generating tube unit 10. Thus, it provides a laser induced liquid jet generating device that is safe for both the operator and the patient as it can apply irradiation of powerful laser beams for a long period of time without the catheter being thermally affected by the laser beams.

A urinary catheter with an improved retaining and activating feature is provided which is a safe device with reduced irritation and discomfort to a patient. The retaining mechanism positioned at the proximal end of the catheter assumes a “close” state for introduction and removal of the catheter into and from the urethral tract, and is transitioned into the “open” state when the catheter is in the bladder by mechanically manipulating the retaining mechanism through the activation mechanism. An actuating linkage wire connected between the retaining mechanism and activation mechanism controllably reciprocates in the channel of the catheter to transition the catheter between the “open” and “closed” states.

A 3-D image observation apparatus includes a reflection type image display panel that has a digital micro mirror device, a magnifying optical system, and at least two light sources. The light sources are positioned at different locations relative to the reflection type image display panel, with the micro mirrors of the digital micro mirror device being variable in tilt angle such that light from a first light source is reflected to the left eye of an observer when the left image is displayed on the display panel in a time-division manner, and light from a second light source is reflected to the right eye of the observer when the right image is displayed on the display panel in a time-division manner. In this manner, one does not need to wear special glasses in order to experience a wide-angle, 3-D viewing experience.

This document provides orthopedic and dental devices and methods for their use. For example, novel bone drills and dental drills are described. The bone and dental drills have at least some centers of mass that are offset from the drills' axis of rotation. Accordingly, the bone and dental drills may rotate and cut using a precessional pattern of motion. The design facilitates bone cutting, chip formation and hauling capacity, irrigation and bone harvesting. In some embodiments, the bone chips are collected in a removable apparatus fixed to the distal portion of the drill, and the collected bone chips can be used for bone grafting.

A device for the assisted loading of a stretcher (2) provided with a chassis (3), comprises at least one driving wheel (4) circumferentially connected to a driving member (5) fed by connectivity member (6) and controlled by controller (7) to activate the at least one driving wheel (4) at least during the loading of the stretcher into the ambulance.

A manually operated pedicle locator instrument measures the static permittivity of matter to locate pedicles in vertebral or bony structures. The locator senses and compares the dielectric constants of the pedicle and the surrounding matter. When the operative component of the locator, the component which contains controlled capacitors, is placed over non-pedicle material, the locator will sense one dielectric constant. However, when it is placed over a pedicle, there is a different dielectric constant. The locator operates on this capacitance difference generated by differences in density. Circuitry in the locator senses this change and sends the change signal to indicator lights located on the locator. A switch on the locator allows the surgeon to select different levels of capacitance in order to identify thicknesses of different bony structures, i.e. structures in cervical, thoracic, and lumbar vertebral bodies.
