FIELD: otorhinolaryngology.SUBSTANCE: under endotracheal anesthesia, an endoscope equipped with optics and an instrument for removing pathological contents of the maxillary sinus are inserted into the nasal passage. The inferior nasal concha is displaced medially using a raspatory. Then, stepping back from the edge of the piriform opening by 1.5–2.0 cm in the caudal direction, a mucoperiosteal flap of the lateral wall is separated in the lower nasal passage. The mucoperiosteal flap is displaced posteriorly, exposing the bone skeleton in the projection of the inferomedial angle of the maxillary sinus. Next, using a cold plasma coblator, in ablation mode, the mucous surface of the bone skeleton is evaporated for 2–3 seconds, followed by coagulation of small vessels. Then, a bone valve measuring 10–15 mm is formed from the exposed bone skeleton. The bony valve is retracted in the caudal direction, forming an antrostomy. A 70-degree endoscope is inserted through the formed antrostomy and the pathological contents of the sinus are visualized. In this case, if the cyst is visualized with a coblator in ablation mode, the cyst is evaporated along with its contents, and the remaining cyst is captured and removed. If a polyp is visualized, the polyp stalk is first evaporated, and then the remaining part of the polyp is removed. If a foreign body is visualized, it is removed with forceps. In this case, if the foreign body is encapsulated or located in the thickness of the mucosa, a coblator in ablation mode evaporates part of the mucosa until the foreign body is exposed, and then removed. Next, the sinus cavity is washed with saline solution. The antrostomy is closed with a bone flap. The formed mucoperiosteal flap is placed back in its original place.EFFECT: method allows for endoscopic endonasal removal of pathological contents from the maxillary sinuses with a minimal risk of cyst / polyp recurrence and postoperative complications, reduced blood loss during surgery, shortened surgical time, postoperative rehabilitation periods, and temporary disability.3 cl, 3 ex

This invention relates to a quick-attachment protective plate for a lower limb prosthesis, comprising a front protective plate, a rear protective plate, clamping arms, and locking handles. The front protective plate has a first connecting groove and a second connecting groove on its inner sides; the rear protective plate has a third connecting groove and a fourth connecting groove on its inner sides. The clamping arms are rotatably connected to the first and third connecting grooves. The locking handles are located on opposite sides of the front and rear protective plates, each locking handle being connected to a shaped slider with an opening groove at its front end. Engaging the two locking handles causes the two shaped sliders to slide inwards, connecting the front and rear protective plates. Simultaneously, the two clamping arms rotate to clamp the lower leg tube. Through the linkage of the locking handles, shaped sliders, and clamping arms, the front and rear protective plates and the lower leg tube can be connected simultaneously, resulting in good stability, fast installation and disassembly, minimal risk of damage or loosening after repeated assembly and disassembly, and good aesthetics.

A system receives, from one or more flow rate sensor circuits, one or more signals that indicate the flow rate of coolant provided to a set of circuit boards. The one or more flow rate sensor circuits are configured to detect the flow rate of the coolant traveling from one or more pumps towards the set of circuit boards. The one or more pumps are configured to direct a flow of the coolant towards the set of circuit boards. The system compares the flow rate of the coolant to a threshold flow rate. The system determines that a total flow rate of the coolant is less than the threshold flow rate. The system causes the autonomous vehicle to perform a minimal risk maneuver in response to determining that the flow rate of the coolant is less than the threshold flow rate.

Embodiments provide a vehicle computer coupled to a vehicle. The vehicle computer may be configured to compute (e.g., generate) a first (e.g., regular, main) trajectory and a second (e.g., fail-safe, minimal risk maneuver) trajectory for the vehicle. Embodiments may provide techniques for incorporating sensor input into the response for managing a minimal risk maneuver. The low-resolution sensor data may be received from a low-resolution sensor having integrated object detection processing such as an automotive radar sensor. The safety processor may modify the second trajectory using the low-resolution sensor data to avoid any new hazards along the second trajectory. Embodiments may also provide, in addition to the low-resolution radar sensor data, pre-computed analysis of the low-resolution radar sensor data from the main processor to the safety processor to reduce the false positives (e.g., false positive object detections) along the second trajectory.
