The specific space 401 may be formed in plural along the surface of the rotation unit 110.

The recovery network 109 may be disposed in a specific space 401 formed on the outer surface of the rotation unit 110, respectively. Here, the recovery network 109 may be implemented in a form in which a net 403 for covering the polyps of the resected body organs is attached to the frame 402 having flexibility. The recovery network 109 may be disposed in a specific space 401 with the net 403 folded on the frame 402. The recovery net 109 may be inserted into a specific space 401 formed on the outer surface of the rotating unit 110 in a folded state in order to recover the cut polyps.

Referring to (a) of FIG. 4, the recovery network 109 may be disposed in a specific space 401 of the rotation unit 110 during endoscopy and procedure. At this time, the recovery network 109 is completely in the specific space 401 of the rotating unit 110 when the endoscopy and procedure are performed, that is, until the recovery network is used to recover the polyps. Can be kept folded.

After the polyp is excised by the ablation snare, at the time when the excised polyp is to be recovered, the recovery network 109 may be exposed from the inside of the specific space 401 to the outside of the specific space 401. In detail, the first control device 115 of the polyp recovery device 114 may couple the forceps 302 with the ring 301 of the recovery network 109 through the recovery line 112 connected to the forceps 302. .

In detail, the recovery network 109 may be exposed to the outside of the specific space 401 when the polyps excised by the ablation snare 108 are sucked by the suction pump. When the polyps are sucked close to the opening 104 in a state exposed to the outside of the specific space 401 of the recovery network 109, the operation of the suction pump stops, and the polyps sucked by the suction pump have no suction power. It can fall down from the point. The recovery net 109 is disposed at the lower end of the endoscope tube 103, thereby recovering the polyps falling down. A detailed configuration in which the polyps are recovered will be described with reference to FIG. 5.

5 is a diagram for explaining an operation of introducing a recovery network from which polyps are collected into a specific space according to an embodiment.

Referring to Figure 5, the polyp recovery device 114 is a polyp 501 that is excised by the ablation snare 108 through the recovery network 109 exposed to the outside of the specific space from the inside of the specific space of the rotation unit 110. Can be recovered. The polyp recovery device 114 may be attached to the endoscope device 101. The polyp recovery device 114 may recover the polyps 501 that have been excised by the ablation snare 108 by controlling the plurality of recovery networks 109 inserted in a specific space using forceps.

In other words, when the cut polyp 501 is sucked by the suction pump, the polyp recovery device 114 may expose the recovery network 109 inserted in the specific space to the outside of the specific space. When the suction pump is exposed to the outside of the specific space 401 of the recovery network 109 and the polyps are sucked adjacent to the opening 104, the operation of the suction pump may be stopped. Polyps that have been sucked by the suction pump may fall down at the point where suction power is lost.

Here, the polyp recovery device 114 may collectively recover the polyps found multiple times using the plurality of recovery networks 109. In detail, when the polyps 501 found in the body organs are cut by the ablation snare 108, the endoscope device 101 may suck the cut polyps 501 using a suction pump. Here, the suction pump may be externally connected to the passage of the opening in order to suck the polyps 501 cut by the ablation snare 108. The suction pump can suck liquids and small objects existing inside the body organs by the operation unit 102 of the endoscope device 101.

At the lower end of the endoscope tube 103, a recovery network 109 for recovering the currently cut polyps 501 among a plurality of recovery networks disposed in a specific space of the rotation unit 110 may be exposed. The recovery network 109 may be prepared in an unfolded state of the recovery network 109. In other words, the recovery network 109 may be coupled to the forceps by the first control device 115 of the polyp recovery device 114 and exposed to the outside of a specific space in order to recover the ablated polyp 501. As the recovery net 109 is exposed to the outside of a specific space, the folded net is unfolded, thereby preparing a state for recovering the polyps.

By inhaling air through the opening 104, the suction pump may suck the polyp 501 cut from the body part where the polyp 501 is excised by the ablation snare 108 to the end of the endoscope tube 103. . The suction pump can release the suction when the sucked polyp 501 is located at the end of the endoscope tube 103. The excised polyp 501 may be dropped into the net of the recovery network 109 as it is, while the suction power by the suction pump is lost. As the polyp 501 is dropped, it may be recovered in the recovery network 109. Each step in which the polyp 501 is sucked will be described with reference to FIG. 9.

Referring to (a) of FIG. 5, the first control device 115 of the polyp recovery device 114 is, in a state in which the polyps 501 are recovered in the recovery network 109, the forceps 302 coupled to the ring of the recovery network. ), it is possible to finally recover the recovery network from which the polyps 501 are recovered.

That is, the polyps recovered in the recovery network may be fixed while hanging at the entrance of a specific space where the recovery network is exposed.

The size of the polyps 501 may be classified into polyps of 1 cm or less or polyps of 1 cm or more. Polyps 501 of 1 cm or more are known to occur more than villi-shaped cells belonging to polyps of 1 cm or less, as cells in the form of villi according to endoscopic tissue findings. And, polyps of 1 cm or more are more likely to develop cancer than polyps of 1 cm or less. Accordingly, the present invention can individually collect each polyp in order to perform a biopsy on the polyps generated inside the body organs.

In consideration of this, the specific space formed on the outer surface of the rotation unit 110 may be formed in a small size such that the recovery net and the forceps 302 are moved or the recovery net is stored. For example, the specific space may have a size of 1 cm or less and may be formed in the form of a hole passing through a portion of the rotating unit. In other words, when the size of the polyp 501 is larger than the width of the inlet of the specific space, the polyp 501 cannot pass through the specific space. In the present invention, by fixing the polyp 501 in the form of suspending the polyp 501 recovered through the recovery network on the end of the endoscope tube 103, the polyp 501 may be finally recovered.
