  • Patent number: 11992278
    Abstract: Provided is a robot for vascular intervention. The robot for vascular intervention comprises: a catheter driving unit for rotating and translating a catheter extending in a longitudinal direction while having the longitudinal direction as an axis; a guide wire driving unit provided at a side of the catheter driving unit, drawing a guide wire into the catheter by translating the guide wire, and rotating the guide wire coaxially with the catheter; a micro-catheter driving unit provided at a rear of the catheter driving unit and translating the micro-catheter in a path coaxial with the catheter that is different from draw-in and draw-out paths of the guide wire when the guide wire is drawn out from an inside of the catheter; and a micro-guide wire driving unit provided at a rear of the micro-catheter driving unit, and drawing a micro-guide wire into the micro-catheter by translating the micro-guide wire, and rotating the micro-guide wire coaxially with the micro-catheter.

  • Publication number: 20210353473
    Abstract: A menstrual cup for insertion into a vaginal canal having a vaginal wall for prevention of leakage of menstrual blood may include: a body having an accommodating cavity portion opened upward is formed; a concave portion extending from the upper end of the body to gradually decrease in diameter; and a circular guide rib extending from an upper end of the concave portion to gradually increase in diameter. It can be easily inserted into the vagina so that it is deformable, and the size of the insertion direction is reduced. Not only it is effective, but when inserted it into the vagina, the circular guide rib comes into close contact with the inner wall of the vagina by restoring force for preventing a menstrual blood from leaking.

  • Publication number: 20200222244
    Abstract: The present invention relates to a tension attenuating hypertrophic scar reduction film, and more particularly, the tension attenuating hypertrophic scar reduction film that prevents the opening of the wound by tension by distributing or removing the tension transmitted to the wound by attaching the film of different thickness or asymmetric size to the wound where the tension is applied.

  • Patent number: 9326839
    Abstract: Disclosed is a tension delivery device for preventing urinary incontinence, which includes: Retzius space-insertion portions which are respectively to be inserted into the Retzius spaces positioned on the left side and right side of the urethra and move in response to the pressure or the Retzius spaces; and a urethral support portion which extends convergently from the Retzius space-insertion portions and serves to support the urethra upward, wherein the lateral cross section of the urethral support portion becomes thinner from Retzius space-insertion portions toward the distal end, and a mesh structure may be provided along the outer surface of the tension transfer device. The device can sufficiently inhibit urinary incontinence, and is minimally invasive so that damage associated with an invasive method can be reduced.

  • Patent number: 8574147
    Abstract: Disclosed is a pressure-to-tension conversion device for treating urinary incontinence. The pressure-to-tension conversion device includes resilient sections which are inserted in and occupy Retzius spaces positioned in left and right sides of the urethra in front of the urinary bladder, respectively, and a support extending below the urethra and across the resilient sections in a ā€œVā€ shape, wherein if the resilient sections are deformed as the abdominal pressure increases and the Retzius spaces contract, the support is tensioned, thereby supporting the urethra, so that the urinary incontinence can be treated. Consequently, the length of operation time for transplanting the pressure-to-tension conversion device can be shortened, a complication or a side effect can be reduced, and the charges of operation can be reduced. In addition, expensive operation materials can be substituted by the pressure-to-tension conversion apparatus, the costs for operation materials can be saved.
