Methods and devices for maintaining nasal passages open after nasal surgery are provided. The post-operative device includes a first tubular member with a first proximal end and a first distal end, and a second tubular member with a second proximal end and a second distal end, where the first proximal end is connected to the second proximal end with a bridging member. The method includes inserting the post-operative device into the nasal passages and before, during or after inserting the device into the nasal passages, adjusting the medical device to accommodate the nasal passages by manipulating a flexible member of the medical device.

Methods and devices for maintaining nasal passages open after nasal surgery are provided. In some embodiments, the method of the present invention includes initially cleaning at least some of the bodily fluids from the nasal passages of a patient after the nasal surgery; providing a post-operative device having a first tubular member with a first proximal end and a first distal end, and a second tubular member with a second proximal end and a second distal end, where the first proximal end is connected to the second proximal end with a bridging member, and the post-operative device is splintless; inserting the first distal end and the second distal end into the nasal passages of the patient to a location where the first proximal end and the second proximal end each protrude beyond the nostril opening of the patient; and placing a packing material at least partially around each tubular member. In some embodiments of the present invention, a specialized speculum is provided to facilitate placing packing material around the tubular members of the medical device. Medical kits for use following nasal surgery are also provided.

The invention discloses a cold compress device for nasal surgery in rhinology clinic. The device includes two armrests. A rotary shaft is rotatably connected with the opposite ends of the two seat handrails. A rotating column is fixedly sleeved on two rotating shafts, a mounting cavity is arranged in one side of the armrest of the seat, and a first motor is fixedly installed in the mounting cavity, the output end of the first motor penetrates the wall of the mounting cavity and is fixedly connected with adjacent rotating shafts, and the top ends of the two rotating columns are movably connected with a plug shaft. A telescopic structure capable of flexibly adjust that rotation angle is arranged on the arm rest of the seat on both sides of the seat, and two telescopic structures are directlyprovided with a chin placing structure and a nose cold compressing structure which are matched with each other, As that position of the cold compress structure can be adjusted up, down, left, right and omni-directional accord to the operation position of the patient, the patient can adjust his own face position or the position of the cold compress structure according to the demand of the best position of the cold compress state of the patient, so as to achieve the b treatment state and improve the experience effect of the cold compress device.

The invention discloses a preparation method of a water-soluble sponge with density gradient and its application in the field of nasal cavity hemostasis. The preparation method of the water-soluble sponge with density gradient includes the following steps: (1) preparing a polymer aqueous dispersion, denoted as dispersion A; (2) thickening the aqueous polyurethane dispersion, denoted as dispersion B; (3) ) Mix the dispersions A and B, and then pour it into a centrifuge tube for centrifugation; (4) quickly freeze the centrifuge tube containing the sample in step (3); (5) take out the thoroughly frozen sample for freeze-drying to obtain a Density gradient water soluble sponge. The sponge is particularly suitable for nasal surgery, used as a hemostatic material, and has the application effects of compression hemostasis, no adhesion, and water flushing ablation.

The invention discloses an auxiliary mirror-holding robot for nasal cavity surgery, which includes three parts: a frame, a robot body and an endoscope, wherein, according to the direction from top to bottom, the robot body includes a sequentially connected endoscope horizontal movement mechanism, The endoscope rotation mechanism, the endoscope swing mechanism and the endoscope vertical movement mechanism constitute four degrees of freedom on the horizontal plane and the vertical direction of the robot body. The four motion mechanisms of the robot body are driven by independent servo motors, and the movements of each mechanism do not interfere with each other; each servo motor is controlled by an external computer control system, using three-dimensional image navigation technology, to control the trajectory, positioning and positioning of the endoscope. Air attitude control. The coordination and synchronization of the movements of the moving parts of the invention are good, and it has four degrees of freedom, which can fully meet the needs of the auxiliary operation of the nasal cavity surgery endoscope. Its overall structure is simple and compact, with reasonable layout, accurate positioning, high precision, and flexible attitude adjustment in the air.

The invention discloses an angle-freely-changeable nasal sinus mirror, comprising a handle, a stainless steel tube, an observation device and an angle adjusting device. The angle adjusting device comprises an end plate arranged at the end of the stainless steel tube. A transparent front cover, wherein an outwardly protruding cover is arranged at the front end of the end plate, and a cavity is formed between the transparent front cover and the end plate; Flip plate, which can be flipped with respect to the end plate, and the flip angle range is not less than 0 DEG to 75 DEG; a steel wire with one end connected to the flap and the other end extending to the handle; a telescopic adjust mechanism is arranged on the handle and is connected with the steel wire to control the steel wire to move along the stainless steel pipe and drive the turnover plate to turn over; and the objective lens of the observation device is arranged on the flap. The angle-freely-changeable nasal sinus mirror can see the best operation position in any direction of nasal surgery, and only one nasal sinus mirror is required for the whole operation process, so that the operation is convenient to carry out and the equipment resources are saved. The angle-freely-changeable nasal sinus mirror can convert the lens angle to see the best operation position in any direction of nasal surgery.
