- a protrusion 620 for applying pressure to the needle actuating means 500 is formed on the inner surface of the control piece 610, and when the needle 330 is completely exposed to the outside of the body entry part 300, the protrusion 620 on one side It is seated in the seating groove 513 on one side to prevent the needle operating means 500 from moving arbitrarily, and when the needle 330 completely enters the inside of the body entry part 300, the protruding part 620 on the other side moves to the seating groove on the other side. 513 to prevent the needle operating means 500 from moving arbitrarily, thereby ensuring stability during polyp removal surgery.
- the snare operating means 400 moves forward from the main body 100, the polyp removal line 320 moves forward, exposing the snare 310 to the outside of the body entry part 300, and the needle operating means 500 ) is moved forward from the main body 100, the needle 330 is exposed to the outside of the body entry part 300 while the chemical solution supply line 340 moves forward, and when the needle 330 is exposed, the snare operating means 400 is operated.
- the snare 310 enters the inside of the body entrance part 300, and when the snare 310 is exposed, the needle operating means 500 moves backward from the body 100 to insert the needle 330. ) to enter the inside of the body entry unit 300.
- the medical snare device of the present invention includes a needle that inflates the size of the polyp by injecting a chemical solution into the polyp so that the snare can be easily inserted when removing the polyp generated in the organ as described above, and ,
- the forward/backward movement of the snare to cut and remove the polyp is accurately performed, the rotation of the snare is precisely performed, and the bleeding of the part cut and removed by the snare is minimized to reduce the patient's pain and speed recovery.
