[0028] like Figure 1-3 As shown, a tracheotomy auxiliary device provided in this embodiment includes a positioning seat 1 and a cutting ring 2.
[0029] like Figure 2 As shown, an air cavity groove 11 is provided on the top of the positioning seat 1, and a piston push column 12 is slidably inserted on the top of the air cavity groove 11, and the piston push column 12 is tightly fitted with the inner wall of the air cavity groove 11, and a plurality of circular arc air channels 13 are evenly distributed around the air cavity groove 11 inside the positioning seat 1, and both ends of the circular arc air channels 13 face downward, one end of the circular arc air channel 13 is connected to the bottom of the air cavity groove 11 and the other end is provided with a needle hole 131 that passes through the bottom of the positioning seat 1, and the size of the needle hole 131 is smaller than the size of the circular arc air channel 13, and a piston block 14 is slidably provided in the circular arc air channel 13, and the piston block 14 is tightly fitted with the inner wall of the circular arc air channel 13, and an arc needle 141 matching the size of the needle hole 131 is provided at one end of the piston block 14 close to the needle hole 131, and the tip of the arc needle 141 faces the needle hole 131, and a ring track 15 is provided on the outer periphery of the bottom of the positioning seat 1.
[0030] The cutting ring 2 is sleeved and rotatably mounted on the outer side of the ring rail 15 , and a cutting blade 21 capable of protruding out of the bottom of the positioning seat 1 is mounted on the cutting ring 2 .
[0031] When in use, the bottom of the positioning seat 1 is first placed on the outside of the exposed trachea, and the piston push rod 12 is pressed downward. The air pressure will push each piston block 14 to move toward the needle hole 131, so that the tip of the arc needle 141 can pass through the needle hole 131 and pierce into the trachea. The arc needle 141 will puncture along the arc trajectory of the arc airway 13, so that the arc needle 141 can hook back to the front wall of the airway after passing through the trachea, which can prevent the tip of the arc needle 141 from approaching the rear wall of the airway, and can hook and fix the positioning seat 1 on the trachea in a hook shape, and then the cutting blade 21 is extended out of the bottom of the positioning seat 1 to pierce into the trachea, and the cutting ring 2 is rotated to make the cutting blade 21 cut the trachea along the annular path, so that the cut tracheal window is regular and neat, so as to facilitate the subsequent insertion of the tracheal tube. The present invention is not only easy to operate, but also can ensure the regularity of the section of the tracheal window, and can also prevent sharp objects from injuring the airway, thereby improving the safety of operation.
[0032] It should be noted that one end of the needle hole 131 in the arc airway 13 is the end away from the air cavity groove 11, so that the arc needle 141 can hook back toward the center of the positioning seat 1 when puncturing the trachea, and then hook the positioning seat 1 on the tracheal tissue removed from the tracheal window.
[0033] Preferably, the blade surface of the cutting blade 21 is curved in an arc shape, and the curvature of the cutting blade 21 matches the curvature of its moving path, so that the cutting edge of the cutting blade 21 can always face the cutting position to prevent the incision from being offset.
[0034] Preferably, a limit ring 161 is installed above the air cavity groove 11 through the bracket 16, and the inner diameter of the limit ring 161 is adapted to the size of the piston push rod 12. The side wall of the piston push rod 12 near the top of itself is surrounded by a plurality of receiving grooves 121, and each receiving groove 121 is provided with an elastic strip 122. The elastic strip 122 can be made of an elastic iron sheet or an elastic plastic sheet. One end of the elastic strip 122 is connected to the bottom side of the receiving groove 121 and the other end extends obliquely to the outside of the receiving groove 121. When the piston push rod 12 is pushed into the air cavity groove 11 When the elastic strip 122 is inside, the elastic strip 122 will pass through the inner circle of the limit ring 161. Since the inner diameter of the limit ring 161 is adapted to the size of the piston push rod 12, the elastic strip 122 will be pushed into the receiving groove 121 when passing through the inner circle of the limit ring 161. When the elastic strip 122 completely passes through the limit ring 161, the elastic strip 122 will pop out of the receiving groove 121 again under the action of its own elastic force, and then the elastic strip 122 will prevent the piston push rod 12 from moving out of the air cavity groove 11, thereby preventing the arc needle 141 from retracting and causing the positioning seat 1 to lose its fixation.
[0035] In one embodiment, a movable ring body 17 is slidably sleeved up and down on the outer side of the positioning seat 1. Specifically, a guide groove 18 is longitudinally provided on the outer wall of the positioning seat 1, and a guide block 172 slidably connected to the guide groove 18 is provided on the inner side of the movable ring body 17. An annular groove 171 is provided on the outer side of the movable ring body 17. A slide groove 22 is longitudinally provided on the inner side of the cutting ring 2, and a slider 23 is slidably installed in the slide groove 22. A sliding pin 231 slidably connected to the annular groove 171 is provided on the slider 23, and the sliding pin 231 can slide along the path of the annular groove 171. The cutting blade 21 is installed at the bottom of the slider 23. When the movable ring body 17 moves downward, it can drive the slider 23 to move downward, so that the cutting blade 21 can be protruded from the bottom of the positioning seat 1 so as to cut the trachea. When the movable ring body 17 moves upward, it can drive the slider 23 to move upward, so that the cutting blade 21 is received in the slide groove 22, so that the cutting blade 21 can be prevented from scratching personnel when the device is not in use, and the cutting blade 21 can be protected.
[0036] Furthermore, a pressing plate 123 is provided at the top of the piston push rod 12 to expand the pressing surface of the piston push rod 12 for easy pressing. A connecting ring 124 is provided on the bottom side of the pressing plate 123. The bottom end of the connecting ring 124 is connected to the movable ring body 17. The piston push rod 12 is connected to the movable ring body 17 through the connecting ring 124. While driving the arc needle 141 to puncture and fix the trachea, it can also synchronously drive the cutting blade 21 to move out of the bottom of the positioning seat 1, thereby simplifying the operating steps and facilitating the tracheal cutting operation.
[0037] like Figure 3As shown, preferably, the path of the annular groove 171 is wavy and undulates up and down, so that when the cutting ring 2 is rotated, the slider 23 can continuously rise and fall along the path of the annular groove 171 in the slide groove 22, so that the cutting blade 21 can cut the trachea while rotating and moving up and down, thereby improving the cutting ability of the cutting blade 21 and ensuring that the tracheal window is smoothly cut.
