Embodiment 1
[0018] The combined surgical resection device for pterygium involved in this embodiment, its main structure includes four parts: corneal fixator, linear knife fixer, linear knife, and linear knife penetrator; the main structure of the corneal fixator Including cornea fixing ring 1, first handle 2, groove 3, fixing teeth 4, connecting shaft 5, track groove 6, cornea fixing ring 1 is a medical metal ring structure with a diameter of 12mm, a height of 4mm, and a thickness of 0.5mm The two sides of the corneal fixing ring 1 are equipped with the first handle 2 with a semicircular fork structure through the connecting shaft 5, the holding end of the first handle 2 is in the same plane as the plane where the semicircular fork is located, and the first handle 2 can be wound around the connecting shaft 5 Rotate relative to the cornea fixing ring 1, the bottom of the cornea fixing ring 1 is provided with an arc-shaped groove 3 at the position opposite to the first handle 2, so as to fre...
Embodiment 2
[0023] The combined surgical resection device for pterygium involved in this embodiment has the same main structure as in Embodiment 1, the first buckle groove 9, the second buckle groove 10, the third buckle groove 11, and the fourth buckle groove. The gap between the upper and lower sides of the buckle groove 12 is a blunt sawtooth structure, and the size of the gap is 0.01-0.5 mm, which can block the linear knife 13 .
Embodiment 3
[0025] The combined surgical resection device for pterygium involved in this embodiment has the same main structure as that in Embodiment 1 or Embodiment 2, and one end of the linear knife 13 is fixedly provided with an indicator plate 15, which is made of medical PVC material. The formed disc structure has a diameter of 3 to 4 mm and a thickness of 1 to 2 mm. One side of the indicating disc 15 is red, and the linear knife 13 is fixed between the upper and lower surfaces of the indicating disc 15 and passes through the center of the indicating disc 15. When indicating When the red side of the disc 15 faces upward, the teeth of the linear knife 13 face to the left of the indicating disc 15; It is used to judge and determine the direction of the cutter teeth. When in use, when passing the linear knife 13 through the linear knife threader 14, determine the orientation of the knife teeth according to the cutting direction and select the direction of the indicator disk 15, then pin...
