Description

Technical Field

[0001] This invention relates to the field of thoracic surgical medical auxiliary devices, specifically a drainage fixation and protection device for thoracic surgical treatment. Background Technology

[0002] Thoracic surgery is a discipline that specializes in the diagnosis and treatment of diseases of organs within the thoracic cavity, mainly the esophagus, lungs, and mediastinum. During thoracic drainage surgery, a drainage catheter needs to be inserted into the surgical wound to drain the internal fluid. During the drainage surgery, the catheter needs to be fixed to prevent displacement.

[0003] Current fixation methods typically involve wrapping the wound with tape. However, since patients usually undergo drainage in a semi-reclining position to facilitate the drainage of fluid from the pleural cavity, this fixation method leaves the drainage tube suspended in the air. This can cause the tube to sway, potentially leading to secondary injury and hindering the drainage treatment. Therefore, this fixation method is not comprehensive enough.

[0004] Therefore, in order to solve the above problems, the present invention proposes a drainage fixation and protection device for thoracic surgery. Summary of the Invention

A fixing mechanism 1 is provided on the bottom wall of the mounting frame 1 at the position corresponding to the through groove 11. 2. A connecting rod 13 is slidably connected to the middle position of the side wall of the mounting frame 1. A handle 14 is fixedly connected to one side of the connecting rod 13, and a pressing mechanism 15 is fixedly provided on the other side of the connecting rod 13.

A clamping frame 22 is fixedly connected to one side of each connecting rod 19.

[0026] Specifically, the transmission mechanism 9 includes symmetrically arranged vertical blocks 91, a lead screw 92 rotatably connected between the two vertical blocks 91, a guide rod 93 fixedly connected between the two vertical blocks 91, a rotating disk 94 fixedly connected to one side of the lead screw 92 through one of the vertical blocks 91, and a first pressing rod 95 threadedly connected to the lead screw 92 near the middle position.

[0027] Specifically, the vertical block 91 in the transmission mechanism 9 is symmetrically fixedly connected to the top wall of the connecting pipe 4, the guide rod 93 in the transmission mechanism 9 is slidably connected to the first extrusion rod 95, the transmission mechanism 9 is located at the top of the first pressure seat 8, and the guide rod 93 in the transmission mechanism 9 is located at the bottom end of the lead screw 92. The guide rod 93 facilitates the movement of the first extrusion rod 95.

[0028] Specifically, the fixing mechanism 12 includes a support frame 121, a movable rod 122 is slidably connected to the bottom wall of the support frame 121, a fixing block 123 is fixedly connected to the top of the movable rod 122, a pull ring 124 is fixedly connected to the bottom of the movable rod 122 through the bottom wall of the support frame 121, and a fixing spring 125 is fixedly connected to the bottom of the fixing block 123 at the position corresponding to the movable rod 122.

[0029] Specifically, the support frame 121 in the fixing mechanism 12 is fixedly connected to the corresponding slot 11 position on the bottom wall of the mounting frame 1. The pull ring 124 in the fixing mechanism 12 is located at the bottom end of the support frame 121. The bottom end of the fixing spring 125 in the fixing mechanism 12 is fixedly connected to the top end of the bottom wall of the support frame 121. The moving rod 122 in the fixing mechanism 12 is located at the hollow position of the fixing spring 125. The bottom end of the fixing spring 125 is fixedly connected to the support frame 121 to facilitate the compression and contraction of the fixing spring 125 when the fixing block 123 moves.

[0030] Specifically, the extrusion mechanism 15 includes a movable plate 151. Guide blocks 152 are fixedly connected to the top and bottom of the movable plate 151 at positions corresponding to the slide groove 10. Support blocks 153 are fixedly connected to one side of each of the two guide blocks 152. Second extrusion rods 154 are fixedly connected to the opposite ends of the two support blocks 153. Symmetrically arranged through slots 155 are provided on the movable plate 151. A connecting block 156 is fixedly connected to the bottom end of the support block 153.

[0031] Specifically, the moving plate 151 in the extrusion mechanism 15 is fixedly connected to one side of the connecting rod 13, the two guide blocks 152 in the extrusion mechanism 15 are slidably connected inside the slide groove 10, and the opposite ends of the two second extrusion rods 154 in the extrusion mechanism 15 are located inside the pressure bearing groove 20. The slidable connection between the guide block 152 and the slide groove 10 facilitates the movement guidance of the moving plate 151.

[0032] Specifically, the two connecting rods 19 are slidably connected to the limiting rod 17, and the opposite ends of the two connecting rods 19 are fixedly connected to the return spring 18. One side of each of the two connecting rods 19 passes through the through groove 155 in the extrusion mechanism 15 and is fixedly connected to the clamping frame 22. The limiting rod 17 facilitates the movement of the connecting rods 19, and the moving connecting rods 19 facilitate the compression and retraction of the return spring 18.

[0033] When using the device, first, the entire drainage fixation device needs to be fixed to the edge of the bed. Medical staff can align the two clamping brackets 22 inside the mounting frame 1 with the edge of the bed, hold the mounting frame 1 with one hand and the handle 14 with the other, and pull. The handle 14 will move the connecting rod 13, which in turn will move the moving plate 151. The moving plate 151 moves towards the mounting groove 16. The movement of the moving plate 151 will also move the support block 153 and the guide block 152. The movement of the support block 153 will move the second compression rod 154, which will then contact the bearing. Inside the pressure groove 20, as the second pressing rod 154 moves continuously, the two connecting rods 19 are pressed and move towards the center. The limiting rod 17 guides the movement of the two connecting rods 19. Then, the continuously moving second pressing rod 154 presses against the second bearing seat 21, causing the connecting rods 19 to move continuously. At the same time, the movement of the connecting rods 19 will compress and contract the return spring 18. The simultaneous movement of the connecting rods 19 towards the center will drive the clamping frame 22 to move. The moving clamping frame 22 will clamp the edge corner of the bed, while the bottom end moves... The support block 153 will cause the connecting block 156 to touch the sloping position of the fixing block 123. At this time, the fixing block 123 will move downward under the pressure of the connecting block 156. The downward movement of the fixing block 123 will drive the moving rod 122 to move and also compress the fixing spring 125. When the clamping frame 22 fixes the edge corner of the bed, the concave part at the bottom of the connecting block 156 will also correspond to the top of the fixing block 123. At this time, the fixing block 123 will be reset under the action of the fixing spring 125. Then the fixing block 123 will be inserted into the connecting block 156. At this time, the position of the clamping frame 22 is... Once the drainage tube is secured, it is then introduced into the connecting tube 4. To secure the drainage tube, simply rotate the screw 92. The screw 92 will drive the first compression rod 95 to move towards the first pressure seat 8. The continuously moving first compression rod 95 will press the first pressure seat 8 towards the bottom. At this time, the first pressure seat 8 will drive the round rod 5 and the pressure tube 6 to move. Then, the pressure tube 6 will press down on the drainage tube and thus secure it. The clamping force depends on the situation. To release the overall fixation, simply pull the fixing block 123 out of the recessed part of the connecting block 156 through the pull ring 124, and the other mechanisms will automatically reset.
