[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A drainage tube after endoscopic thyroid surgery, which comprises a drainage tube main body, the drainage tube main body is arranged on an inner tube, the head end of the inner tube is a puncture section, and a sharp end sheath is arranged at the head end; an outer tube is arranged on the outer wall of the inner tube, and a fixing device for fixing the drainage tube is arranged at one end of the outer tube close to the sharp end sheath.

[0007] Specifically, the fixing device comprises a telescopic fixing frame, the telescopic fixing frame has a telescopic sliding structure, a sleeve is movably connected to the telescopic sliding structure, the sleeve slides up and down on the telescopic sliding structure, and the telescopic fixing frame is controlled to be closed or expanded.

[0008] Specifically, a circular ring double-ear clamping block is arranged below the sleeve, and the circular ring double-ear clamping block is fixedly arranged between the inner tube and the outer tube and is in conformity with the sleeve.

[0009] Specifically, the length of the outer tube is less than that of the inner tube, the hole diameter of the outer tube is greater than that of the inner tube, and the bottom ends of the inner tube and the outer tube are flush.

[0010] Specifically, the tip sheath is funnel-shaped with a narrow front and a wide back, facilitating the drainage tube to penetrate the skin.

[0011] Specifically, the tip sheath is further provided with a drainage hole. The tip sheath can be placed in the patient's body, and the drainage tube body is placed outside the patient's body.

[0012] The utility model has the following advantages:

[0013] The utility model provides a kind of endoscope thyroid postoperative drainage tube, and the skin inner face is expanded to be horn type by telescopic fixing frame structure, skin outside is again used circular ring double ear block to be stuck, circular ring double ear block (9) can be combined with the sleeve pipe on telescopic fixing frame, inside and outside combination structure, avoid the tedious operation of suture, more convenient, it also reduces the risk of infection simultaneously.
