Human tissue radiation protector with auxiliary method of radiotherapy
The present invention provides a human tissue radiation protector with auxiliary method of radiotherapy, wherein said human tissue radiation protector comprises an interconnected expander, a syringe and a marker set onto the expander; said marker is made of radiopaque materials, which could assist the expander in positioning; as well as multiple radiation dosage detector capable of measurement the radiation dosage at different positions of the expander; said method allows to place the expander of the human tissue radiation protector between the tumor and nearby human tissues or organs so as to separate them, and assist the expander in positioning via the marker and measurement the radiation dosage via the radiation dosage detector.
Membrane for protecting intraocular tissues and the protection methods used thereof
According to embodiments, a membrane with a flat or curved surface is provided for protection of intraocular tissues. The membrane can be used to cover the cornea for protecting corneal endothelial cells, to cover the anterior and posterior surface of the iris, or to cover the surface of the posterior capsule for separating the intraocular tissues. The membrane has a layered structure, which is composed of a collagen and a hydrophilic biopolymer or an organic polymer material. In particular, the membrane has high transparency and high water retention in a wet state.
Apparatus and method for applying light in ocular and periocular areas
A removable tip for alight 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.
Radiation protection equipment and radiation protection system provided with radiation protection equipment
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.
Radiation shielding implants and methods of use
A removable implant having a radiation shield adapted to reduce radiation exposure to one or more secondary radio-sensitive tissues during breast cancer radiation therapy is provided herein, the implant including: a flexible casing having: a base adapted for anchoring the implant to a chest wall of a patient; a cap disposed on the base; and a radiation-absorbing core adapted to absorb at least a portion of cardiac impact zone radiation when compared to a control, wherein the cap encloses the radiation-absorbing core, and wherein the radiation-absorbing core includes: a flexible solid polymer; and a plurality of radiation-absorbing members dispersed throughout the flexible solid polymer. In another embodiment, the implant further includes a breast tissue expander disposed on a top face of the flexible casing of the implant. Methods of use of the described implants are also provided herein.
ELECTROSURGICAL DEVICES, DIRECTIONAL REFLECTOR ASSEMBLIES COUPLEABLE THERETO, AND ELECTROSURGICAL SYSTEMS INCLUDING SAME
A directional reflector assembly includes a tubular shaft having a proximal end and a distal end and adapted to operably engage an electrosurgical ablation probe, and a conical aperture having a proximal open apex joined to a distal end of the tubular shaft, and a distal open base, wherein an interior volume of the tubular shaft is open to the conical aperture.
RADIO FREQUENCY ABLATION COOLING SHIELD
A medical assembly and method are provided to effectively treat abnormal tissue, such as, a tumor. The target tissue is thermally ablate using a suitable source, such as RF or laser energy. A cooling shield is placed in contact with non-target tissue adjacent the target tissue, and actively cooled to conduct thermal energy away from the non-target tissue. In one method, the cooling shield can be placed between two organs, in which case, one of the two organs can comprise the target tissue, and the other of the two organs can comprise the non-target tissue. In this case, the cooling shied may comprise an actively cooled inflatable balloon, which can be disposed between the two organs when deflated, and then inflated. The inflated balloon can be actively cooled by pumping a cooling medium through it. In another method, the cooling shield can be embedded within the non-target tissue. In this case, the cooling shield can comprise one or more needles. If a plurality of needles is used, they can be embedded into the non-target tissue in a series, e.g., a rectilinear or curvilinear arrangement. The needle(s) can be actively cooled by jumping a cooling medium through them.
MEMBRANE FOR PROTECTING INTRAOCULAR TISSUES AND THE PROTECTION METHODS USED THEREOF
According to embodiments, a membrane with a flat or curved surface is provided for protection of intraocular tissues. The membrane can be used to cover the cornea for protecting corneal endothelial cells, to cover the anterior and posterior surface of the iris, or to cover the surface of the posterior capsule for separating the intraocular tissues. The membrane has a layered structure, which is composed of a collagen and a hydrophilic biopolymer or an organic polymer material. In particular, the membrane has high transparency and high water retention in a wet state.
Electrosurgical devices, directional reflector assemblies coupleable thereto, and electrosurgical systems including same
A directional reflector assembly includes a tubular shaft having a proximal end and a distal end and adapted to operably engage an electrosurgical ablation probe, and a conical aperture having a proximal open apex joined to a distal end of the tubular shaft, and a distal open base, wherein an interior volume of the tubular shaft is open to the conical aperture.
Roll subsystems for robotic stapling and cutting systems
Systems and subsystems for cutting and stapling tissue are disclosed. More specifically, the present disclosure relates to systems, devices, and subsystems for attachments for robotic surgeries. The surgical instrument is a robotic attachment including a roll subsystem. The roll subsystem comprises a rotatable shaft having a longitudinal axis, a roll input puck engageable with a roll robotic output, a worm gear coupled to and rotatable by the roll input puck, and a worm follower coupled to the rotatable shaft. Rotation of the roll input puck causes the worm gear to rotate the worm follower and thereby roll the rotatable shaft about its longitudinal axis.
