Description

Technical Field

[0001] The invention belongs to the technical field of surgical auxiliary tools, and in particular relates to a material cutting device for a surgical positioning patch. Background Art

[0002] A drainage tube is a tube placed in the body cavity. Its main function is to help guide the fluid in the body cavity after surgery, such as blood, pus, urine, gastric juice, etc. Therefore, drainage tubes are further divided into chest tubes placed in the chest cavity, abdominal drainage tubes placed in the abdominal cavity, and gastric tubes.

[0003] Before surgeries in the chest, abdomen and other cavities, drainage tubes must generally be inserted first. To ensure that the inserted drainage tubes do not shift during the operation, after the drainage tubes are inserted, medical positioning stickers are needed to stick and fix the drainage tubes to the skin. However, the shapes of ordinary positioning stickers on the market are basically regular rectangles. In order to better fix the drainage tubes, a notch needs to be cut on one edge of the positioning sticker before pasting and the drainage tube needs to be passed through the notch when pasting. The existing notch cutting is all done manually, and there are at least 2-3 drainage tubes used in the operation, and each drainage tube requires more than one positioning sticker. Therefore, if the multiple positioning stickers required for the operation are all cut manually, the operation is very troublesome, time-consuming and laborious, resulting in an inconvenient operation process, which urgently needs to be solved.

[0051] Two first transition blocks 104 and two second transition blocks 117 are respectively provided, and the positions of the two first transition blocks 104 and the two second transition blocks 117 can be adjusted respectively; if only one hole needs to be cut on the positioning sticker, the hole cutter 114 is only installed on one of the first transition blocks 104, and when the electric cylinder 106 pushes the two first transition blocks 104 to move downward during operation, the first transition block 104 without the hole cutter 114 is not in contact with the positioning sticker, and the hole cutter 114 descends and contacts the second traction bar 119 to raise the driving plate 118, and the sheet cutter 120 cuts the side wall of the positioning sticker drilled with the driving plate 118 when it is raised; when two holes need to be cut on the positioning sticker, the hole cutters 114 are installed on both first transition blocks 104, and then the positions of the two first transition blocks 104 and the two second transition blocks 117 are adjusted to cut two through holes with notches on the positioning sticker.

[0052] The following is a detailed description of cutting a through hole on the positioning sticker as an example: after pressing the first driving block 109, the second driving plate 128 pushes the first auxiliary block 130 out of the first directional groove, and the second return spring 127 pushes the third guide block 126 to move out of the third limiting channel, and the storage tray 102 pops out from the first compartment. The storage tray 102 continues to be pulled outward so that the positioning sticker can be laid flat in the storage tray 102. When the third guide block 126 is against the fourth traction bar 1253 and cannot continue to move outward, the handle 107 is pulled relative to the storage tray 102, the first transmission bar 112 moves relative to the storage tray 102, and the positioning plate 111 rises; after the positioning sticker is placed in the storage tray 102, The handle 107 is pushed relative to the storage tray 102, and the connecting strip 129 rotates to drive the first traction strip 113 to move, and the positioning plate 111 moves downward to press the positioning sticker on the storage tray 102, thereby fixing the positioning sticker on the storage tray 102; after the positioning sticker is fixed, the storage tray 102 is pushed into the first compartment, and after the storage tray 102 drives the positioning sticker to move into the first compartment, the switch 108 is pressed to start the electric cylinder 106, and the first driving plate 115 moves downward to push the first transition block 104 to move downward, and the hole cutter 114 descends to drill a hole in the positioning sticker, and the second traction strip 119 is inserted into the first opening groove, and the electric cylinder 106 drives the first driving plate 115 to move upward, and the reference spring pushes the first transition block 104. When the hole cutter 114 moves upward, the driving plate 118 is driven to move upward under the action of the magnetic block. When the second guide block 1181 moves to above the bridging rod 124, the second guide block 1181 is at the top of the second limiting channel and cannot move further. The hole cutter 114 is disengaged from the second traction bar 119, and the bridging rod 124 fixes the second guide block 1181 at the current position. The sheet cutter 120 is inserted into the through hole of the positioning sticker; after the first transition block 104 is reset, the first driving block 109 is pressed, and the first auxiliary block 130 is disengaged from the first directional groove. The second return spring 127 pushes the third guide block 126 to move out of the third limiting channel, and the inner wall of the through hole of the positioning sticker is against the sheet cutter 120. The sheet cutter 120 shears the positioning sticker and cuts a notch on the side wall of the through hole of the positioning sticker, and the cut positioning sticker falls into the receiving tray 103; after the storage tray 102 does not move, continue to pull the storage tray 102 outward until the storage tray 102 cannot be pulled, and the third guide block 126 abuts against the fourth traction bar 1253, and the fourth traction bar 1253 drives the adapter plate 125 to move, and the adapter plate 125 drives the bridging rod 124 to move, and after the driving plate 118 raises the supporting force, the first return spring 1182 pushes the driving plate 118 to move downward and reset; continue to pull the handle 107 relative to the storage tray 102, the first transmission bar 112 moves to make the positioning plate 111 rise, and the cut positioning sticker can be directly taken out.

[0053] If the storage tray 102 needs to be removed, the third guide block 126 cannot move further after moving to the fourth traction strip 1253, and a push rod-shaped tool is inserted into the matching cavity 101a to push the third guide block 126 to move. The third guide block 126 enters the sixth guide channel and is offset from the fourth traction strip 1253, so that the storage tray 102 can be directly removed from the first compartment.

[0054] The receiving tray 103 can be directly pulled out from the second compartment so as to clean the broken materials in the receiving tray 103 .
