Step S4: The pull block is pulled, the pull block stretches the pull rope, and the pull rope drives the sliding block one and the sliding block two to move, respectively. Step S5: when the pull rope moves the sliding block one, the sliding block one slides along the sliding groove at the bottom of the front end plug plate, and the front end plug plate rotates, the front end plug plate pushes the foreign matter from the back to the inside of the storage assembly, and the foreign matter is collected in the storage assembly, and the foreign matter is wrapped by the storage assembly; Step S6: when the pull rope moves the sliding block two, the sliding block two extrudes the liquid in the hydraulic cavity through the piston rod, sends the liquid into the bladder bag, and expands the bladder bag, and separates the foreign matter with edges and corners from the nasal cavity through the expansion of the bladder bag.

[0012] The beneficial effects of the present application are: (1) The base pipe is inserted into the nasal cavity, the storage assembly and the clamping assembly are moved close to the foreign matter in the nasal cavity, the storage assembly is opened in advance when the storage assembly and the clamping assembly are close to the foreign matter, the push-pull ring sleeve is pushed to move the connecting rod and the inclined surface ring synchronously, the inclined surface ring drives the arc-shaped plate to open under the cooperation of the inclined surface ring and the inclined surface of the arc-shaped plate, the storage assembly is attached to the nasal cavity, and the nasal cavity is continuously opened by continuously pushing the push-pull ring sleeve, so that the nasal cavity is lifted, the nasal cavity at the front end of the foreign matter is formed into a low position, the tissue fluid and blood exuded from the blocked part of the nasal cavity flow into the storage assembly, and then the tissue fluid and blood in the nasal cavity are removed, so that a small amount of tissue fluid and blood exuded from the blocked part does not affect the operation of the clamping assembly.

[0013] (2) The pull block is pulled to stretch the pull rope, and the pull rope moves the sliding block one and the sliding block two respectively.

[0030] The present application is used at the beginning of work, referring to Figure 1As shown, the accommodation assembly 2 is in a retracted state, and the clamping assembly 6 is inwardly gathered, thereby effectively avoiding scratching the nasal cavity lining by the clamping assembly 6.

[0031] It should be noted that when the foreign body with edges and corners is blocked inside the nasal cavity, it is easy to scratch the nasal cavity lining, causing a small amount of tissue fluid and blood to seep out at the blocked place, and the tissue fluid and blood fill the gap between the nasal cavity and the foreign body, making it difficult for the clamping assembly 6 to pass through the gap and affecting the operation of the clamping assembly 6.

[0032] The base pipe 1 is inserted into the nasal cavity, and the accommodation assembly 2 and the clamping assembly 6 are moved close to the foreign body inside the nasal cavity. When the accommodation assembly 2 and the clamping assembly 6 approach the foreign body, the accommodation assembly 2 is opened in advance by pushing the push-pull ring 3, and the push-pull ring 3 drives the connecting rod 5 and the inclined ring 7 to move synchronously. Under the cooperation of the inclined ring 7 and the inclined surface of the arc-shaped plate 201, the inclined ring 7 drives the arc-shaped plate 201 to open, so that the accommodation assembly 2 fits the nasal cavity.

Further, the present application can also be used with a liquid suction device to completely clean the seepage.

[0033] Pulling the push-pull ring 3 drives the connecting rod 5 and the inclined ring 7 to move outward, and the arc-shaped plate 201 contracts under the action of the contraction spring 10, so that the opening of the accommodation assembly 2 is larger than the foreign body. Then, the base pipe 1 is pushed, and the front end plug-in plate 603 and the rear end plug-in plate 602 pass through the gap between the nasal cavity and the foreign body, so that the front end plug-in plate 603 is located behind the foreign body, and the rear end plug-in plate 602 is located between the contact surface of the nasal cavity and the foreign body. Figure 6 Pulling the pull block 4 stretches the pull rope 609, which drives the sliding block one 605 and the sliding block two 608 to move, respectively. When the pull rope 609 drives the sliding block one 605 to move, the sliding block one 605 slides along the sliding groove 615 at the bottom of the front end plug-in plate 603, and the front end plug-in plate 603 rotates. The front end plug-in plate 603 pushes the foreign body from behind to the inside of the accommodation assembly 2, and the foreign body is collected in the accommodation assembly 2. When the foreign body is taken out of the nasal cavity, the edges and corners of the foreign body can avoid scratching the nasal cavity, causing secondary damage.

[0034] When the pull rope 609 drives the sliding block two 608 to move, the sliding block two 608 extrudes the liquid in the hydraulic chamber 613 through the piston rod 614, and sends the liquid into the bladder 611, so as to make the bladder 611 swell. The bladder 611 swells to separate the foreign body with edges and corners from the nasal cavity, avoiding the edges and corners of the foreign body scratching the local nasal cavity during the process of pushing the foreign body into the accommodation assembly 2 by the front end plug-in plate 603.

[0038] Referring to Figures 1-8 , the present application is a kind of nasal foreign body extractor extraction method, the method is applied to the nasal foreign body extractor as described in the above embodiment, the method comprises the following steps: Step S1: the base pipe 1 is inserted into the nasal cavity, so that the accommodation assembly 2 and the clamping assembly 6 are close to the nasal cavity internal foreign matter, when the accommodation assembly 2 and the clamping assembly 6 are close to the foreign matter, the accommodation assembly 2 is opened in advance, the push-pull ring sleeve 3 is pushed, the push-pull ring sleeve 3 drives the connecting rod 5 and the inclined surface ring 7 to move synchronously, under the cooperation of the inclined surface ring 7 and the inclined surface of the arc-shaped plate 201, the inclined surface ring 7 drives the arc-shaped plate 201 to open, so that the accommodation assembly 2 is attached to the nasal cavity; Step S2: with the continuous pushing of the push-pull ring sleeve 3, the accommodation assembly 2 is continuously opened, the nasal cavity is lifted, the nasal cavity in front of the foreign matter forms a low position, and the tissue fluid and blood exuded from the nasal cavity blockage are flowed into the accommodation assembly 2; Step S3: the push-pull ring sleeve 3 is pulled, the push-pull ring sleeve 3 drives the connecting rod 5 and the inclined surface ring 7 to move outward, the arc-shaped plate 201 is contracted under the action of the contraction spring 10, the opening of the accommodation assembly 2 is greater than the foreign matter, then the base pipe 1 is pushed, the front end plug plate 603 and the rear end plug plate 602 pass through the gap between the nasal cavity and the foreign matter, so that the front end plug plate 603 is located behind the foreign matter, and the rear end plug plate 602 is located between the contact surface of the nasal cavity and the foreign matter; Step S4: the pull block 4 is pulled, the pull block 4 stretches the pull rope 609, and the pull rope 609 drives the sliding block one 605 and the sliding block two 608 to move respectively; Step S5: when the pull rope 609 drives the sliding block one 605 to move, the sliding block one 605 slides along the sliding groove 615 at the bottom of the front end plug plate 603, and the front end plug plate 603 rotates, the front end plug plate 603 pushes the foreign matter from the rear to the inside of the accommodation assembly 2, and the foreign matter is put into the accommodation assembly 2, and the foreign matter is wrapped by the accommodation assembly 2; Step S6: When the pull rope 609 drives the slider 608 to move, the slider 608 extrudes the liquid in the hydraulic cavity 613 through the piston rod 614, sends the liquid into the bag 611, promotes the bag 611 to expand, and separates the foreign matter with edges and corners from the nasal cavity through the expansion of the bag 611.

[0039] The implementation principle of the present application is: At the beginning of the work, referring to Figure 1 As shown in the figure, the accommodation assembly 2 is in the state of being gathered, and the clamping assembly 6 is gathered inward, thereby effectively avoiding the clamping assembly 6 from scratching the nasal cavity lining.

[0040] It should be noted that when the foreign matter with edges and corners is blocked in the nasal cavity, it is easy to scratch the nasal cavity lining, causing a small amount of tissue fluid and blood to seep out of the blocked part, and the tissue fluid and blood fill the gap between the nasal cavity and the foreign matter, making it difficult for the clamping assembly 6 to pass through the gap and affecting the operation of the clamping assembly 6.

[0041] The base pipe 1 is inserted into the nasal cavity, and the accommodation assembly 2 and the clamping assembly 6 are moved close to the foreign matter in the nasal cavity. When the accommodation assembly 2 and the clamping assembly 6 are close to the foreign matter, the accommodation assembly 2 is opened in advance by pushing the push-pull ring 3, so that the push-pull ring 3 drives the connecting rod 5 and the inclined ring 7 to move synchronously. Under the cooperation of the inclined ring 7 and the inclined surface of the arc-shaped plate 201, the inclined ring 7 drives the arc-shaped plate 201 to open, so that the accommodation assembly 2 is attached to the nasal cavity. With the continuous pushing of the push-pull ring 3, the accommodation assembly 2 is continuously opened, the nasal cavity is lifted, the nasal cavity at the front end of the foreign matter is formed into a low position, and the tissue fluid and blood seeping out of the blocked part of the nasal cavity flow into the accommodation assembly 2, thereby removing the tissue fluid and blood in the nasal cavity, and avoiding the influence of a small amount of tissue fluid and blood seeping out of the blocked part on the operation of the clamping assembly 6.

[0042] The push-pull ring 3 is pulled, the push-pull ring 3 drives the connecting rod 5 and the inclined ring 7 to move outward, and the arc-shaped plate 201 is contracted under the action of the contraction spring 10, so that the opening of the accommodation assembly 2 is greater than that of the foreign matter. Then the base pipe 1 is pushed, and the front end plug-in plate 603 and the rear end plug-in plate 602 pass through the gap between the nasal cavity and the foreign matter, so that the front end plug-in plate 603 is located behind the foreign matter, and the rear end plug-in plate 602 is located between the contact surface of the nasal cavity and the foreign matter. Figure 6 The pull rope 609 drives the slider 605 and the slider 608 to move, respectively. When the pull rope 609 drives the slider 605 to move, the slider 605 slides along the sliding groove 615 at the bottom of the front end plug-in plate 603, and the front end plug-in plate 603 rotates. The front end plug-in plate 603 pushes the foreign matter from behind to the inside of the accommodation assembly 2, and the foreign matter is put into the accommodation assembly 2. When the foreign matter is taken out of the nasal cavity, the edges and corners on the foreign matter can be avoided to scratch the nasal cavity, causing secondary damage.
