[0026] like Figures 1-4 As shown, an adjustable-aperture surgical drape includes a drape body 1 with an opening area 2. The opening area 2 is circular and includes several fan-shaped pieces 3, which are cut from the opening area 2. The arc-shaped ends of the fan-shaped pieces 3 are connected to the drape body 1, and the tips of the fan-shaped pieces 3 are fitted with elastic rings 4 and fixedly connected to traction ropes 5. The drape body 1 is equipped with a traction component, and rope-attached counterweights 6 are arranged on the drape body 1 around the opening area 2. The design of the rope-attached counterweights 6 eliminates the need for cloth clips during use. After the drape is laid out, the rope-attached counterweights 6 naturally fall, pulling the drape to make it flat. The traction ropes 5 are connected to the traction component, allowing the fan-shaped pieces 3 to open and close, thereby controlling the size of the opening area 2. Through the design of the traction component and the fan-shaped plate 3, after the power rope 8 is pulled, the rotating shaft 11 rotates, which in turn drives the connecting shaft 10 and the winding wheel 12 to rotate, so that the traction rope 5 is wound on multiple adjustment frames 15, pulling the tip of the fan-shaped plate 3 closer to the fixed block 7, causing the fan-shaped plate 3 to fold. The opening formed by the folds of multiple fan-shaped plates 3 is the surgical opening, realizing flexible adjustment of the size and shape of the opening, and meeting the requirements of different surgical sites and operations.

[0027] The traction assembly includes a fixed block 7 and a power rope 8. The fixed block 7 has a receiving groove 9. There are several fixed blocks 7. The number of fixed blocks 7 is the same as the number of fan-shaped pieces 3. Fixed rings 16 are fixedly connected between the multiple fixed blocks 7. The power rope 8 passes through all the receiving grooves 9 in sequence.

[0028] The inside of the accommodating groove 9 is movably mounted with a connecting shaft 10, the outer surface of the connecting shaft 10 is sleeved with a rotating shaft 11, and the power rope 8 is wound around the rotating shaft 11 once. Since the power rope 8 is wound around the rotating shaft 11 once, the rotating shaft 11 rotates after the power rope 8 is pulled.

[0029] The top end of the connecting shaft 10 penetrates through the fixed block 7 and is fixedly connected with a winding wheel 12, the inside of the winding wheel 12 is a hollow structure, the top of the winding wheel 12 is threadedly connected with a rotating rod 13, and the bottom end of the rotating rod 13 is provided with a conical head 14.

[0030] The winding wheel 12 is penetrated through with a plurality of adjusting frames 15, and the plurality of adjusting frames 15 are distributed in a circumferential array around the winding wheel 12.

[0031] One end of the adjusting frame 15 is in abutting connection with the conical head 14, and one of the adjusting frames 15 is fixedly connected with the traction rope 5. Since one end of the traction rope 5 is connected with the adjusting frame 15, the traction rope 5 is wound on the plurality of adjusting frames 15.

[0032] Working principle:

[0033] Using the device, the sheet main body 1 is laid on the patient, the opening area 2 is aligned with the operation site, then the rotating rod 13 is rotated according to the operation requirement, the height of the conical head 14 is adjusted, with the change of the height of the conical head 14, the adjusting frame 15 moves, the rotating radius of the adjusting frame 15 changes when rotating, then one end of the power rope 8 is pulled, since the power rope 8 is wound around the rotating shaft 11 once, the rotating shaft 11 rotates after the power rope 8 is pulled, then the connecting shaft 10 and the winding wheel 12 are rotated, since one end of the traction rope 5 is connected with the adjusting frame 15, the traction rope 5 is wound on the plurality of adjusting frames 15, the tip of the sector-shaped sheet 3 is pulled to the fixed block 7, the sector-shaped sheet 3 is folded, the elastic ring 4 is at the folding position of the sector-shaped sheet 3, and exerts a pulling force on the folding position of the sector-shaped sheet 3 to the center of the opening area 2, the holes surrounded by the folding positions of the plurality of sector-shaped sheets 3 are the operation holes, the size of the operation holes is controlled by controlling the displacement of the power rope 8, the moving speed of the tip of the sector-shaped sheet 3 is controlled by controlling the position of the adjusting frame 15, and different-shaped operation holes are formed by the speed difference.

[0034] The design of the rope counterweight 6 makes it unnecessary to use a towel clamp when in use, and the rope counterweight 6 naturally falls after the sheet is laid, the sheet can be pulled to be flat.
