Scientists Propose Laser Scalpel with a ‘Curved’ BladeTBMG-3831101/01/2021
Scientists from Tomsk Polytechnic University and Saratov State University teamed up with colleagues from Taiwan and proposed to make a laser “blade” for a medical scalpel with a specified curved shape using a photonic “hook.” Currently there are laser scalpels only with an axisymmetric focus area, i.e., with a cylindrical blade. According to scientists, changing the shape of the blade will expand the possibilities of using the laser in medicine, while it is about two times thinner than the cylindrical option. The concept and its rationale are published in the Journal of Biophotonics.
Implantable Sensor Could Measure Bodily Functions and Safely BiodegradeTBMG-3830901/01/2021
Sensors that monitor a patient’s condition during and after medical procedures can be expensive, uncomfortable, and even dangerous.

Smart, Self-Powered Knee ImplantsTBMG-3796711/01/2020
Knee replacement surgery is the most common joint replacement procedure, with the number of surgeries increasing every year. This surgery is being performed for younger, more active patients who are faced with a dilemma: When they undergo the surgery, they are expected to remain physically active for their overall health but that activity can also wear down the new implant. Often, doctors don’t know if patients are overexerting themselves until they begin to develop symptoms. By that point, the damage to the implant has already been done. For a young patient, going through knee replacement surgery every five or 10 years is a daunting task but finding the perfect balance of activity levels to maintain the integrity of the implant has been equally daunting.
Improved Electrosurgical Grounding Pad Prevents Patient Skin Burn During ElectrosurgeryTBMG-3806011/01/2020
The high-power electrosurgical and radio-frequency (RF) ablation devices that apply a high level of RF current to the patient for extended periods can increase the risk of patient skin burns at the grounding pad’s attachment site. Safety measures that have been proven effective using traditional electrosurgical procedures may not be sufficient to prevent grounding pad burns when used in procedures that require any combination of high current, long activation times and the use of conductive fluids (e.g., saline) for irrigation or distention. 1

Biorubber Glue Offers Faster Surgical RecoveryTBMG-3784910/01/2020
Researchers have developed a new type of surgical glue that can help join blood vessels and close wounds faster and may also serve as a platform to deliver pain relief drugs. The glue can bond soft tissues, including muscle and blood vessels, even when their surfaces are wet. Named CaproGlu, it is activated by a low dose of ultraviolet (UV) light that cures it in seconds, turning it from a liquid glue into a solid but flexible biorubber — a biocompatible material that can be resorbed by the tissue after a few weeks.
Origami-Inspired Miniature ManipulatorTBMG-3783610/01/2020
Minimally invasive laparoscopic surgery, in which a surgeon uses tools and a tiny camera inserted into small incisions to perform operations, has made surgical procedures safer for both patients and doctors. Surgical robots further assist surgeons by allowing them to manipulate multiple tools at once with greater precision, flexibility, and control than is possible with traditional techniques. These robotic systems are extremely large, often taking up an entire room and their tools can be much larger than the delicate tissues and structures on which they operate.

Smart Design: How to Develop Your Next Orthopedic Product During the COVID-19 PandemicTBMG-3734708/01/2020
The advent of the COVID-19 pandemic has created uncertainty and delays in procedures, but hospitals and surgeons still need a steady supply of product, meaning that the orthopedics industry must keep innovating. One thing is certain, 2020 will be a turbulent year for procedure demand. Early on, analysts predicted that because many orthopedic procedures are elective, they would be postponed to help free up space for critically ill patients. While the recovery of orthopedic procedures has begun more quickly than analysts initially expected, it seems likely it will take longer than expected to reach full recovery as we look into 2021. June ordering patterns were already much higher than May, but the quicker recovery may indicate a second decline (W-shaped) versus a sharp decline followed by a quick recovery (V-shaped).

Hydrogel Contact Lens to Treat Eye DiseaseTBMG-3744708/01/2020
Corneal melting is a condition that is a significant cause for blindness worldwide. The incurable eye disease can be initiated by a number of different causes such as autoimmune diseases (like rheumatoid arthritis, Lupus, or Stevens-Johnson syndrome), chemical burns, or some surgical procedures (like LASIK and cataract procedures). The patient’s cornea melts due to the uncontrolled production of certain zinc-dependent enzymes called matrix metalloproteinases (MMPs) by the patient’s immune cells in the cornea. To help prevent this, a new hydrogel was developed that deactivates those enzymes by removing the zinc ions.
