AI Technical Summary
In neurosurgery, the traction sutures of the neurosurgical pad are long and flexible, making them prone to tangling and knotting during automated production, which reduces production reliability.
The system employs a combination of a negative pressure adsorption module and an air blowing pipe. The negative pressure adsorption module adsorbs the cotton sheet body, while the air blowing pipe blows away the traction line, aligning it in a fixed direction. Combined with the design of the upright plate and the take-up belt, this ensures that the traction line maintains linear alignment during the take-up process.
It enables automated, synchronous, directional material collection along the traction line, avoiding tangling, improving production reliability and efficiency, and reducing the need for manual sorting.

[0002] In neurosurgery operation, brain cotton piece (nerve operation pad) is a kind of key consumables, its main part is usually attached to a length more than 30 centimeters of traction line (also called fiber line). Traction line is placed outside the body when using in operation, it is convenient to take out non-woven fabric dressing piece after operation, so its reliable connection with cotton piece and orderly arrangement when postoperative material collecting are crucial.
[0003] In the automatic production process of traditional nerve operation pad, the cotton piece after slitting is transferred to the material collecting belt by the negative pressure adsorption mechanism. However, due to the long length and soft texture of the traction line, the existing technology only relies on the adsorption of the main body of the cotton piece for material taking and transferring, which causes the traction line to entangle and knot due to inertial swing, air flow disturbance or mutual contact during movement.

DETAILED DESCRIPTION
[0022] As Figures 1-3In the present invention, a negative pressure receiving mechanism for a nerve surgical pad includes a chassis equipped with a traction wire welding module 1 and a cutting module 2, and includes a material taking module 3 and a material receiving belt 4. The material receiving belt 4 is positioned in the output direction of the cutting module 2. The material taking module 3 is equipped with a negative pressure adsorption module 12, which is driven by the material taking module 3 to achieve reciprocating motion between the cutting module 2 and the material receiving belt 4.
[0023] The machine casing is provided with a vertical plate 7, which extends toward the material receiving belt 4. An air blowing pipe 8 is provided close to one side of the vertical plate 7, and the air blowing pipe 8 is set toward the material receiving belt 4.
[0024] In a preferred embodiment, the material receiving module 3 includes a track 10 arranged laterally on one side of the receiving belt 4, a slide 11 on the track 10, and a negative pressure adsorption module 12 arranged on the slide 11.
[0025] In a preferred embodiment, a drag chain 6 is provided on the track 10, and the drag chain 6 drives the slide 11 to move horizontally along the track 10.
[0026] In a preferred embodiment, the slide 11 is provided with a receiving plate 5, the negative pressure adsorption module 12 is provided on the receiving plate 5, and the receiving plate 5 is also provided with a negative pressure pipe 13 connected to the negative pressure adsorption module 12.
[0027] In a preferred embodiment, the receiving plate 5 on the slide 11 is movably connected to the slide 11, and the receiving plate 5 is pneumatically controlled to move vertically relative to the slide 11.
[0028] In a preferred embodiment, the air blowing pipe 8 is located on the opposite side of the traction wire 902 on the nerve surgical pad 9, and the air blowing pipe 8 is used to blow away the traction wire 902 placed on the upright plate 7.
[0029] In a preferred embodiment, the upright plate 7 is attached to and parallel to the air blowing pipe 8, with one end of the upright plate 7 fixed to the chassis of the slitting module 2 and the other end extending above the surface of the receiving belt 4.
[0030] Combined with appendix Figure 4 The existing structure of the nerve surgical pad 9 includes a barium wire 901 and a traction wire 902 approximately 30cm long. Due to the relatively long length of the traction wire 902, entanglement occurs during the material collection process. This invention discloses a negative pressure material collection mechanism for the nerve surgical pad 9. During the material collection operation of the nerve surgical pad 9:
[0031] The traction wire welding module 1 welds the traction wire 902 to the cotton pad substrate at a preset position. Then the substrate enters the cutting module 2 and is cut into independent nerve surgical pads 9.
[0032] After the cutting is completed, the sliding seat 11 moves along the track 10 to above the neurosurgical pad 9 product in the cutting module 2, the receiving plate 5 is lowered to the surface of the neurosurgical pad 9 by the air cylinder, the negative pressure suction module 12 is started, and the cotton piece main body 901 is sucked. After suction, the sliding seat 11 moves reversely to above the receiving belt 4, the receiving plate 5 releases the negative pressure, and the cotton piece main body 901 falls to the surface of the receiving belt 4. At this time, the traction line 902 is placed on the top of the vertical plate 7.
[0033] The blowing pipe 8 continuously blows air flow to blow the traction line 902 placed on the vertical plate 7 to the other side of the vertical plate 7, so that it is laid on the surface of the receiving belt 4 and extends along the side of the belt. Since the end of the vertical plate 7 is close to the belt, the traction line 902 cannot rebound under the action of the air flow, ensuring that all the traction lines 902 of the cotton pieces are arranged towards the same side without crossing and winding.
[0034] The receiving belt 4 operates in an intermittent motion mode, and the above receiving operation is performed once each time. The subsequent cotton pieces are sequentially sucked, transferred and arranged, and finally form a neat stack of the traction lines 902 aligned on one side, which is directly conveyed to the packaging station.
[0035] In addition, for the length change of the traction line 902 (such as more than 40 cm), the following adjustments can be made to achieve compatibility:
[0036] Increase the air flow pressure of the blowing pipe 8 (such as 0.4 MPa) or prolong the blowing time to ensure that the longer traction line completely passes over the vertical plate 7;
[0037] Adjust the extension length of the vertical plate 7 so that the end is increased to 10 mm from the surface height of the belt to provide more swing space for the long traction line;
[0038] The vertical stroke of the receiving plate 5 is expanded to 80 mm to meet the stacking requirements of thicker cotton pieces.
