Referring to fig. 1, in the embodiment of the present application, the drainage strip fixing tube 60 is a conical tube made of stainless steel. The drainage strip fixing tube 60 has a head end with a relatively large opening and a tail end with a relatively small opening. The drainage silver is inserted into the fixed pipe 60 of drainage strip by the head end of the fixed pipe 60 of drainage strip, because the fixed pipe 60 of drainage strip is the conical tube for the drainage silver is close to the inner wall extrusion of the fixed pipe 60 of drainage strip by the fixed pipe 60 of drainage strip more at the part of the fixed pipe 60 tail end of drainage strip, thereby makes the more stable fixing of drainage silver in the fixed pipe 60 of drainage strip.
Specifically, the head end of the drainage strip fixing tube 60 is inclined towards the side where the downward bending part 12 is located, so that the drainage cotton strip is convenient to be close to the eyeball of the patient.
With continued reference to fig. 1, the support arm 50 is curved in an arc, and the support arm 50 is a bent stainless steel wire and is welded between the lower bent portion 12 and the drainage strip fixing tube 60. The curved support arm 50 of arc can be better laminating people's face temporal side to make the head end of the fixed pipe 60 of drainage strip be closer to patient's eyeball, in order to make things convenient for the drainage silver to carry out the drainage.
In order to facilitate the rotation of the adjusting screw 20, a knob 40 is connected to the upper end of the adjusting screw 20 for the medical staff to operate with fingers. The knob 40 is made of stainless steel material, and vertical anti-slip threads 41 are arranged on the side wall of the knob 40 to prevent fingers of medical staff from slipping when operating the knob 40.
