DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] When implementing: Figure 1-5 As shown, a constant temperature demisting device for a nasal endoscope comprises: a liquid storage cylinder 1 and an endoscope body 2, the inner wall of the liquid storage cylinder 1 is fixedly connected with a partition 101, the bottom of the partition 101 and the inside of the liquid storage cylinder 1 are filled with heat transfer oil, a heating rod 102 is arranged at the bottom of the partition 101, a pump body 202 is arranged at the top of the partition 101, the bottom of the pump body 202 is connected with a connecting pipe, and the lower end of the connecting pipe passes through the partition 101; a heat exchange sleeve 201 is fixedly connected to the surface of the endoscope body 2, and a spiral heat exchange channel 201 is provided inside the heat exchange sleeve 201 5. One end of the heat exchange channel 205 is connected to the liquid outlet pipe 203, the other end of the liquid outlet pipe 203 is connected to the pump body 202, the other end of the heat exchange channel 205 is connected to the liquid discharge pipe 204, the other end of the liquid discharge pipe 204 passes through the liquid storage cylinder 1 and the partition 101 in sequence; auxiliary mechanism 3, the auxiliary mechanism 3 is arranged inside the liquid storage cylinder 1, and the auxiliary mechanism 3 is used to assist in heating the surface of the endoscope body 2; defogger mechanism 4, the defogger mechanism 4 is arranged on the surface of the endoscope body 2, and the defogger mechanism 4 is used to reduce the influence of fog on the endoscope body 2 during use;

[0023] After the heat exchange oil is heated by the heating rod 102, the heated heat exchange oil is introduced into the outlet pipe 203 through the pump body 202, and injected into the heat exchange channel 205, and then guided back to the liquid storage cylinder 1 for storage through the discharge pipe 204. In this process, the heat exchange oil can heat the surface of the endoscope body 2 through the heat exchange channel 205 and the heat exchange sleeve 201, thereby reducing the influence of fog caused by temperature difference.

[0024] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the defogger mechanism 4 includes a connecting ring 407 that is slidably connected to the surface of the endoscope body 2 and is located below the heat exchange sleeve 201, a blocking block 408 is fixedly connected to the bottom of the connecting ring 407, and two guide rods are fixedly connected to the top of the connecting ring 407, and the upper ends of the two guide rods pass through the heat exchange sleeve 201, and the inner wall of the connecting ring 407 is fixedly connected to a resistance-increasing airbag 409, and the inner edge of the resistance-increasing airbag 409 passes through the connecting ring 407 and contacts with the surface of the endoscope body 2, and the defogger mechanism 4 also includes an air storage chamber 401 opened in the heat exchange sleeve 201, the interior of the air storage chamber 401 is filled with inert gas, and a conduit 406 is arranged inside the heat exchange sleeve 201, one end of the conduit 406 is connected to the air storage chamber 401, and the other end of the conduit 406 is connected to the resistance-increasing airbag 409.

[0025] The inner wall of the air storage cavity 401 is slidably connected with an extrusion plate 402, one side of the extrusion plate 402 is fixedly connected with a connecting rod 403, the other end of the connecting rod 403 passes through the heat exchange sleeve 201 and is fixedly connected with a pull plate 405, and a spring 404 is sleeved on the surface of the connecting rod 403;

[0026] During the use of the endoscope body 2, the endoscope body 2 needs to be inserted into the nasal cavity through the nostrils. During this process, the block 408 can be moved and inserted into the nostrils to cover the nostrils and reduce moisture entering the nasal cavity to form fog that affects the use of the endoscope body 2. During the insertion process, the pull plate 405 can be pulled to drive the connecting rod 403 to make the squeezing plate 402 squeeze the spring 404, and at the same time increase the internal space between the squeezing plate 402 and the side of the spring 404 away from the air storage chamber 401. At this time, the inert gas stored in the resistance-increasing airbag 409 can be introduced into the internal storage of the air storage chamber 401 through the conduit 406 under the elastic force of the resistance-increasing airbag 409 itself. Without contacting the endoscope body 2, the movable endoscope body 2 will not drive the connecting ring 407 and the blocking block 408 to move synchronously, so as to facilitate the use of the endoscope body 2. After the endoscope body 2 is inserted to the desired position, the pull plate 405 can be released to drive the squeezing plate 402 to reset under the action of the spring 404, and the inert gas is squeezed by the squeezing plate 402 to inflate the resistance-increasing airbag 409 through the catheter 406. The inflated resistance-increasing airbag 409 increases the contact area with the endoscope body 2 and the friction between the two, so as to achieve the effect of fixing the position of the connecting ring 407 and the blocking block 408. At the same time, the blocking block 408 reduces the moisture from entering the nasal cavity to form fog and affect the use of the endoscope body 2.

[0027] like Figure 1 and Figure 2As shown, the auxiliary mechanism 3 includes a heat exchange tube 301 disposed inside the liquid storage cylinder 1, the upper end of the heat exchange tube 301 passes through the partition 101 and the liquid storage cylinder 1 in sequence, and the upper end opening is flush with the top surface of the liquid storage cylinder 1, and the inner wall of the heat exchange tube 301 is fixedly connected with a buffer layer 302;

[0028] During the process of heating the heat exchange oil through the heating rod 102, the surface of the endoscope body 2 can be heated by inserting it into the interior of the heat exchange tube 301. Therefore, during use, the heated endoscope body 2 can reduce the impact of fog on it, and at the same time reduce the time for the heat exchange oil to heat it through the heat exchange channel 205, thereby effectively improving work efficiency.

[0029] When the utility model is in use, during the process of the heat exchange oil being heated by the heating rod 102, the surface of the endoscope body 2 can be heated by inserting the endoscope body 2 into the interior of the heat exchange tube 301, and then the heated endoscope body 2 during use can reduce the influence of fog on it, and at the same time reduce the time for the heat exchange oil to heat it through the heat exchange channel 205, thereby effectively improving the work efficiency. During the use of the endoscope body 2, the endoscope body 2 needs to be inserted into the nasal cavity through the nostrils, and during this process, the block 408 can be inserted into the nostrils by moving it, so as to block the nostrils and reduce moisture from entering the nasal cavity to form fog that affects the use of the endoscope body 2.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
