Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a multifunctional suction device for thoracoscopic surgery. Background Art

[0002] The development of single-port thoracoscopy in thoracic surgery has been full of innovations and breakthroughs. In the early days, most thoracic surgeries involved large incisions and were extremely traumatic. With the rise of the concept of minimally invasive surgery, multi-port thoracoscopy emerged, but people still pursued less trauma, so single-port thoracoscopy began to be tried in the early 21st century. It was initially used for simple surgeries such as wedge resection of the lung. Since then, with the accumulation of experience and improvement of instruments, its indications have continued to expand, and it can perform complex surgeries such as lobectomy and mediastinal tumor resection. After a large number of multicenter studies confirmed its advantages, single-port thoracoscopy has become an important choice for minimally invasive thoracic surgery, and it has also been combined with robot-assisted technology for continuous innovation and development.

[0003] Compared to traditional surgery, single-port thoracoscopic surgery offers significant advantages. It requires only a small incision, approximately 3 cm in diameter, significantly minimizing chest wall damage and reducing injury to muscles, nerves, and blood vessels. Postoperative pain is significantly reduced, enabling earlier mobility, faster recovery, and shorter hospital stays. The incision is small and discreet, resulting in excellent cosmetic results. The reduced trauma also reduces complications, making it safer for middle-aged and elderly patients and those with poor cardiopulmonary function.

[0004] However, the existing suction device is separated from the traction device. During the operation, it is generally operated separately by the surgeon and the assistant. However, the operation of multiple instruments can easily lead to instrument collision at the incision, thereby increasing the risk of tissue damage. At the same time, the traditional metal suction device has a relatively fixed suction angle. During the process of pulling the tissue, it is not convenient to achieve real-time flexible bending and deflection, which can easily cause damage to the pulled tissue.

[0005] In response to the above problems, it is urgent to carry out innovative designs based on the original suction devices and traction devices. Summary of the Invention

[0037] As an embodiment of the present invention, the slider 486 is configured as an inclined structure with the inclined surface facing the front side. Two sliders 486 are symmetrically arranged in the swing groove 484, so that when the front end suction device swings back and forth, it can be extended and retracted in the swing direction. A metal snake bone 6 is slidingly limited inside the telescopic rod 51, and an attraction head 7 is installed on the front side of the metal snake bone 6. A flexible metal wire 8 is fixed on the rear side of the metal snake bone 6.

[0038] As an embodiment of the present invention, two rotating disks 9 are rotatably connected in the control disk 2, and the two rotating disks 9 are staggered. Connecting rods 10 are rotatably connected to the two rotating disks 9. The two connecting rods 10 are respectively connected to the push rod 41 and the first piston rod 552. Pull rods 11 are fixedly installed on the two rotating disks 9. The pull rods 11 extend from the upper and lower ends of the control disk 2. An adjusting rocker 12 is installed on one side of the outer periphery of the control disk 2. By pulling the serpentine traction cable through the adjusting rocker 12, the direction of the metal snake bone 6 can be changed, and the chest cavity tissue can be attracted in multiple directions to improve the clarity of the surgical field.

[0039] As an embodiment of the present invention, a serpentine traction cable is provided inside the metal snake bone 6, and the serpentine traction cable and the flexible metal wire 8 pass through the swing rod 483, the elastic telescopic component, the rotating rod 43 and the pushing rod 41 toward the rear end in sequence, and the serpentine traction cable is connected to the adjusting rocker 12. The flexible metal wire 8 extends out of the handheld rod 3 through the control panel 2, and the adsorption blade 53 and the suction head 7 are connected to the external negative pressure equipment through the suction tube 1 through the negative pressure hose with an electromagnetic valve. When the adsorption blade 53 pulls the chest tissue, the electromagnetic valve will automatically cut off the negative pressure provided to the suction head 7, and will automatically open when the adsorption blade 53 is pulled.

[0040] Working principle: When using the multifunctional suction device for thoracoscopic surgery, the medical staff will first grasp the hand-held rod 3 to extend the suction tube 1 into the patient's body through the surgical incision pre-opened on the patient's body. When it is necessary to pull the tissue in the chest cavity, the pull rod 11 at the lower end of the control disk 2 is pushed to drive the rotating disk 9 to rotate, so that the connecting rod 10 pushes the first piston rod 552 to move to the front end, thereby causing the first piston rod 552 to slide in the first oil tank 551, squeezing the oil in the first oil tank 551, forcing the oil to enter the second oil tank 553 through the oil hose, squeezing the rear end of the second piston rod 554, and then pushing the telescopic rod 51 to move to the front end through the front end of the second piston rod 554, and the rack-like structure at the front end of the telescopic rod 51 drives the rear side of the adsorption blade 53 The gear 54 rotates, causing the adsorption blade 53 to gradually expand along the front end of the suction tube 1 until the adsorption surface of the adsorption blade 53 fits the tissue to be pulled. At this time, the medical staff turns on the negative pressure equipment and fixes the tissue by negative pressure adsorption through the micropore array on the adsorption surface of the adsorption blade 53. Then, the pull rod 11 at the upper end of the control disk 2 drives the rotating disk 9 to rotate, so that the connecting rod 10 pushes the push rod 41 to move toward the front end, thereby pushing the movable shell 42 to move toward the front end, driving the guide rod 45 on the inside of the movable shell 42 to slide in the guide groove 44 set on the rear side of the rotating rod 43, so that the rotating rod 43 drives the active bevel gear 46 at its front end to rotate, thereby driving the driven bevel gear 47 to rotate, and then drives the swing rod 483 to swing in the swing groove 484, causing the angle of the front section of the suction tube to deflect.

[0041] At the same time, the resistance block 485 on the outer periphery of the middle section of the swing rod 483 slides on the inclined surface of the slider 486, so that the swing rod 483 drives the front section of the suction tube to deflect and move toward the front end, avoiding hard pulling of the tissue. Finally, the medical staff pushes the flexible metal wire 8 toward the front end to slowly extend the metal snake bone 6 from the telescopic rod 51, and uses the suction head 7 at the front end of the metal snake bone 6 to attract the bleeding near the tissue, and by adjusting the rocker 12 to pull the serpentine traction cable, the direction of the metal snake bone 6 is changed to attract in multiple directions and improve the clarity of the surgical field.
