The invention, in various embodiments, provides systems, devices, and methods for treating urinary incontinence.

The method of reducing pain in a patient by combining a traditional pharmacological treatment with electro-acupuncture or percutaneous electrical nerve stimulation therapy. The pharmacological treatment consists of using analgesics such as morphine sulfate and hydromorphine provided to patients around the clock or as needed for pain. The patient controlled analgesia pump (PCA) is used by patients for self-administering of analgesia as needed. After patient stops using PCA pump narcotic and non-narcotic pain medications are administered mostly orally. Typically, there are two pairs of needle electrodes, two on each leg, connected to two separate outputs of the portable electrical stimulator. The constructions of the needle holder and the stimulator allow a patient to move freely and, if necessary, to carry the device during the entire day.

The present invention relates to hydrogels based on hyaluronic acid based derivatives, that are more resistant than hyaluronic acid alone towards chemical and enzymatic degradation and are endowed with a mix of chemical and mechanical properties such that they are of optimal use in several surgeries, for instance for injection in bone fractures or cavities and for the production of coatings of prostheses in orthopedic surgery, as fillers in cosmetic and maxillo-facial surgery, as anti-adhesion barrier in the prevention of postoperative adhesions in abdominal and abdominal/pelvic surgery, and in general surgery. These hydrogels can be loaded with several different kinds of compounds having pharmacological and biological activity, that are then released from the hydrogel in the site of intervention.

To perform pelvic surgery, a directionally illuminating balloon catheter enters a bladder. The catheter has a multi-lumen shaft. The balloon defines an interior fluidically connected to a balloon inflation lumen and is inflated therethrough. The balloon comprises a light source, a light-radiating surface adjacent the shaft-balloon junction, and a substantially opaque surface disposed at a portion of the balloon other than the light-radiating surface such that the integrated light source illuminates a distal half of the environment outside the balloon. The balloon is inflated while in the bladder. Light from the light source is directed out through the light-radiating surface to illuminate at least a portion of a procedure area opposite the bladder-prostate junction. With the light illuminating the portion of the procedure area, at least a portion of a pelvic surgery is performed at the portion of the procedure area.

The invention discloses a multifunctional retractor for pelvic surgery. The multifunctional retractor for pelvic surgery comprises a plurality of retractors. Each retractor comprises a pull hook, a first cylinder and a second cylinder; in each retractor, a pull rod of the pull hook is fixed to a first support block in a mode that the pull rod can move leftwards and rightwards on the first supportblock, a first motor for driving the movement of the pull hook is arranged on the first support block, the first support block is fixed to a second support block in a mode that the first support blockcan move back and forth on the second support block, a second motor for driving the movement of the first support block is arranged on the second support block, a telescopic rod of a first cylinder is hinged to the left end of the second support block, a second cylinder is hinged to the telescopic rod of the first cylinder, and an telescopic rod of the second cylinder is hinged to the right end of the second support block; the first motors, the second motors, the first cylinders and the second cylinders of all retractors are all connected to a controller. The multifunctional retractor for pelvic surgery can control the movement of the pull hooks in three directions and the rotation of the pull hooks in one direction, and can ensure that the incision can be opened in different directions and angles during the operation to show different opening degrees and opening states.

The invention discloses an evoked potential monitor for real-time monitoring of cavernous nerve damage during laparoscopic surgery, which comprises a stimulating signal output line, a host computer, an evoked potential recording line and a reference electrode line. The stimulation signal output line includes the nerve stimulation probe rod and the output line body connected in sequence. The output line body is connected to the nerve stimulation probe rod and the current stimulation output socket of the evoked potential monitor through the connecting plug; the evoked potential recording line includes positive and negative wires connected respectively. The needle recording electrode and its evoked potential recording line body, and the evoked potential recording line body are respectively connected to the evoked potential signal acquisition socket of the evoked potential monitor; the reference electrode line includes a needle-shaped reference electrode and a reference electrode line body, and the reference electrode line body is connected to the The reference signal acquisition socket of the evoked potential monitor. The invention can realize real-time monitoring of penis cavernous body nerve in laparoscopic radical prostatectomy or radical cystectomy and other pelvic operations.
