DETAILED DESCRIPTION

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 10 The present invention provides a technical solution: a tumor fluid extraction mechanism.

[0033] like Figure 1-Figure 4 As shown, the extraction mechanism includes an extraction bracket 1, a bed slide 2 is installed at the bottom of the extraction bracket 1, and the extraction bracket 1 can slide on the hospital bed where the patient lies through the bed slide 2, and when positioning is required, the extraction bracket 1 is fixed by connecting the first fixing member 3 with the bed body. The extraction bracket 1 adopts a gantry structure, on which a slide 4 is horizontally installed, a horizontal slide seat 5 is slidably installed in the slide 4, and a second fixing member 6 is arranged on the horizontal slide seat 5. When the horizontal slide seat 5 needs to be positioned, the horizontal slide seat 5 is fixed by connecting the second fixing member 6 with the slide 4, so as to facilitate fixation after the puncture point is found, and avoid displacement during puncture and extraction.

[0034] like Figure 3-Figure 6As shown, an end seat 7 is fixedly mounted on the transverse sliding seat 5, and an adjusting seat 9 is rotatably mounted on the end seat 7 via a damping shaft 8. The adjusting seat 9 can be rotatably adjusted on the end seat 7, and is self-fixed by the friction force of the damping shaft 8. A corresponding fixing structure can also be set for the adjusting seat 9. At the same time, angle disks 10 are set on both sides of the end seat 7, and angle scales are set thereon. The actual rotation angle of the adjusting seat 9 can be controlled by a pointer 11 on the damping shaft 8 to find the correct puncture angle.

[0035] like Figure 7 As shown, the adjustment seat 9 is used as the basic structure, and the limit seat 12 is installed thereon. A slide rod 13 is installed in the limit seat 12 for sliding up and down. A top seat 14 is installed on the top of the slide rod 13, and a base 17 is arranged at the bottom. Therefore, the base 17 can be moved up and down by the sliding of the slide rod 13 to complete the puncture work of the extraction tube 20, and a depth scale 15 is set on the side of the adjustment seat 9. The position of the top seat 14 on the depth scale 15 is used to control the actual depth of the puncture to avoid excessive reliance on the experience of medical staff during the extraction of effusion. After the puncture is completed, the position of the base 17 is determined by connecting the third fixing member 16 with the slide rod 13 to avoid displacement of the needle during the extraction of effusion, which causes problems in the extraction of effusion.

[0036] like Figure 7 As shown, clamps 19 are installed on both sides of the base 17 through spring guide rods 18, and the extraction tube 20 can be fixed by the clamps 19. The extraction tube 20 adopts a disposable structure, and the empty and clean extraction tube 20 is fixed in the clamps 19. Therefore, the extraction tube 20 can be adjusted left and right and rotated along with the adjustment seat 9 to find the puncture position. After the puncture position is found, the extraction tube 20 can move down with the base 17 to complete the puncture work, and then the final effusion extraction work can be carried out.

[0037] like Figure 7 As shown, the present invention is provided with a pulling structure for the piston of the extraction cylinder 20, a buckle 21 is installed on the top of the piston of the extraction cylinder 20, and a guide bracket 23 is installed on the base 17 through a support rod 22, and the guide bracket 23 can move and rotate with the base 17, and a lifting seat 24 is slidably installed in the guide bracket 23, and the bottom of the lifting seat 24 is fixedly connected with a hook 26 through a sling 25, and the hook 26 has the ability to move. Through the connection between the hook 26 and the buckle 21, the piston of the extraction cylinder 20 can be connected to the lifting seat 24. When the lifting seat 24 moves up in the guide bracket 23, the piston can be pulled up to generate negative pressure in the extraction cylinder 20, so as to draw the tumor effusion in the patient's body into the extraction cylinder 20. The sling 25 can have a certain elasticity to compensate for the assembly error of the extraction cylinder 20 and ensure that the hook 26 can be connected to the buckle 21.

[0038] The present invention is provided with a lifting drive structure for the movement of the lifting seat 24, and the lifting drive structure is used to control the lifting seat 24. When the extraction cylinder 20 is fixed by the clamp 19, the effect of lifting the piston of the extraction cylinder 20 is achieved. The lifting drive structure has the speed control capability, and the accumulated fluid is extracted at an appropriate speed, avoiding the patient's pain while quickly completing the accumulated fluid extraction work. Example

[0039] The lifting drive structure can adopt an electric structure. The lifting drive structure includes a driving screw 27 installed in the guide bracket 23, and the lifting seat 24 is threadedly connected to the driving screw 27. When the driving screw 27 rotates, the lifting seat 24 can be driven to move in the guide bracket 23. In order to avoid the complexity of the control system, the driving motor of the driving screw 27 is usually set to a fixed power, and the moving speed of the lifting seat 24 is controlled by providing additional friction. A bevel wheel 28 is installed on the lifting seat 24 through a rotating shaft. The bevel wheel 28 has an inclined surface that contacts the surface of the guide bracket 23. Through the rotation of the bevel wheel 28, different positions can be contacted with the guide bracket 23 to generate friction forces of different sizes, so that the moving speed of the lifting seat 24 is controlled. When it is necessary to extract the effusion faster, the friction force is reduced, so that the lifting seat 24 drives the piston of the extraction cylinder 20 to move up quickly to complete the extraction of the effusion. On the contrary, the friction force is increased to avoid excessively fast effusion extraction causing discomfort to the patient. Example

[0040] The lifting drive structure can adopt a manual structure to manually control the extraction speed of the extraction cylinder 20. The lifting drive structure includes a rack 29 fixedly installed in the guide bracket 23, and also includes a base 30 fixedly installed on the lifting seat 24. A climbing wheel 31 is installed in the base 30 through the rotation of the wheel axle. The climbing wheel 31 is meshed with the rack 29. At the same time, a rocker 32 is connected to the wheel axle. The rocker 32 can drive the wheel axle to rotate, thereby causing the climbing wheel 31 to rotate along the rack 29. The reaction force generated can cause the lifting seat 24 to move in the guide bracket 23, control the piston in the extraction cylinder 20, and extract the accumulated fluid in the patient's body at an appropriate speed.

[0041] When the present invention is used: first, when the patient lies on the bed and has been disinfected, the extraction bracket 1 is installed on the bed through the bed slide 2. The two bed slides 2 are respectively connected to the two sides of the bed, and the extraction bracket 1 can be slid to move it above the puncture point. Then, the extraction tube 20 is loaded into the clamp 19, and the position of the extraction tube 20 is adjusted by moving the horizontal slide seat 5 in the slide 4 to move it to the top of the puncture point. According to the preset puncture angle, the angle of the extraction tube 20 is adjusted by rotating the adjustment seat 9, so that the needle of the extraction tube 20 is facing the puncture position, and then the extraction bracket 1 is respectively fixed by the first fixing member 3 and the second fixing member 6. The horizontal sliding seat 5 is fixed, and the angle of the extraction tube 20 is self-fixed by the friction force of the damping shaft 8. Then, the base 17 and the extraction tube 20 are moved to complete the puncture work. At this time, the specific puncture depth can be determined by the depth scale 15, and the lesion is found. The base 17 and the extraction tube 20 are fixed by the third fixing member 16, and then the hook 26 at the bottom of the lifting seat 24 is connected to the ring buckle 21 on the piston of the extraction tube 20, so that the extraction tube 20 and the lifting seat 24 are connected together. Finally, the speed-controllable lifting drive structure is used to drive the lifting seat 24 to move up along the guide bracket 23 to pull the piston, so as to complete the patient's tumor effusion extraction work at a more comfortable speed.
