Description

Technical Field

[0001] This invention relates to the field of catheter fixation technology, specifically to a catheter fixation device for gastrointestinal surgery. Background Technology

[0002] With the development of science and technology, the number of traditional open surgeries in gastrointestinal surgery is increasingly decreasing. Minimally invasive gastrointestinal surgery, benefiting from its smaller incisions, more targeted approach, and easier postoperative recovery, has gained widespread application. Common procedures such as laparoscopic surgery utilize thin catheters inserted into the abdominal wall, providing ample space for the laparoscope and surgical instruments. Therefore, catheter-based interventional therapy, a commonly used medical approach in gastrointestinal surgery, is a fundamental technical prerequisite for minimally invasive gastrointestinal surgery. However, in actual surgical procedures, the interventional catheter needs to be maintained in the same position for extended periods, placing higher demands on the stability and reliability of the catheter fixation device.

[0003] Existing catheter fixation frames lack effective cushioning and anti-slip measures. When the patient moves during surgery, the catheter moves with it, making it prone to displacement, detachment, or even bending. This can also cause the items connected to the catheter to shift or fall off. When these items fall off, they may cause additional injury to the patient, posing a significant safety hazard. Therefore, we propose a catheter fixation frame for gastrointestinal surgery. Summary of the Invention

[0013] This invention provides a fixation device for gastrointestinal surgical catheters. It has the following beneficial effects: (1) The present invention is equipped with a clamping device. When the conduit is needed, the connecting frame, fixed cylinder, pull plate, guide rod, compression spring, piston plate, fixed ring, sliding groove and sliding rod cooperate with each other to pull the pull plate, so that the pull plate drives the piston plate to move upward, so that the two sets of fixed rings move away from each other. After the item is placed, the pull plate is released, so that the two sets of fixed rings fix the item, so that the item connected to the conduit is always inside the fixed ring, which solves the problem that the item connected to the conduit falls off the fixed frame when the fixed frame shakes.

[0014] (2) The present invention provides a support device. When the fixed frame wobbles and tilts to one side, the base, limiting plate, sliding block, tension spring, fixed block, moving block, compression spring, rack, gear, support column, and flipping plate work together to make the sliding block slide to one side along with the fixed frame when it tilts to one side. This causes the sliding block to press against the moving block, which moves downward and drives the rack downward. The meshing rack drives the gear to rotate, which in turn drives the flipping plate to flip outward and make it contact the ground. This solves the problem of the fixed frame tilting to one side. The problem of the fixture tipping over completely after tilting to the side is addressed. Simultaneously, when the fixture's tilt is only slight due to swaying, the base, moving block, compression spring, flipping plate, compression block, compression spring, locking block, and limit spring work together to ensure that the flipping plate remains within the inner wall of the base until the moving block fully compresses the compression block. At this point, the locking block stops limiting the flipping plate, causing it to flip outwards. This solves the problem of the flipping plate easily flipping outwards when the fixture's sway is slight, thus preventing an increase in the probability of accidental contact between the fixture and a person.

[0015] (3) The present invention is equipped with a pressing device. When the fixed frame tilts to one side, the sliding block, sleeve, tension block, moving spring, L-shaped connecting rod, connecting rod, reset spring, support rod, rotating plate and load-bearing block cooperate with each other to make the sliding block move to one side and drive the sleeve to move to one side together. This causes the L-shaped connecting rod to drive the load-bearing block on the rotating plate to move in the opposite direction of the tilt, so that the weight on the tilted side is greater than that on the tilted side. This solves the problem that the fixed frame cannot be restored after tilting and causes the fixed frame to move with the guide tube. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-8 One embodiment of the present invention is: a fixation frame for gastrointestinal surgical catheters, including a base 1, a caster wheel 2 fixedly connected to the bottom of the base 1, a support block 3 fixedly connected to the inner wall of the base 1, a fixing column 4 fixedly connected to the top of the support block 3, and the fixing column 4 penetrates the base 1 and is fixedly connected at the penetration point. A connecting frame 5 is rotatably connected to the outer wall of the fixing column 4. A clamping device is provided at the connecting frame 5 to prevent the material on the connecting frame 5 from falling off when the material shakes. A support device is provided at the base 1 to prevent the fixation frame from shifting and thus tilting. The clamping device includes a fixed cylinder 61, a pull plate 62, a guide rod 63, a compression spring 64, a piston plate 65, a fixed ring 66, a sliding groove 67, and a sliding rod 68. The outer wall of the fixed cylinder 61 is fixedly connected to the inner wall of the connecting frame 5, and the fixed cylinder 61 penetrates the connecting frame 5, with a fixed connection at the penetration point. The outer wall of the piston plate 65 is slidably connected to the inner wall of the fixed cylinder 61. The bottom of the guide rod 63 is fixedly connected to the top of the piston plate 65, and the guide rod 63 penetrates the fixed cylinder 61, with a slidable connection at the penetration point. The bottom of the pull plate 62 is fixedly connected to the guide rod 63. The top of the fixed cylinder 61 is fitted with the bottom of the pull plate 62. The inner wall of the fixed cylinder 61 is provided with a sliding groove 67, which limits the piston plate 65. One end of the compression spring 64 is fixedly connected to the top of the piston plate 65, and the other end is fixedly connected to the inner wall of the fixed cylinder 61. The top of the sliding rod 68 is fixedly connected to the bottom of the piston plate 65, and the sliding rod 68 passes through the fixed cylinder 61 and is slidably connected at the penetration point. The outer wall of the fixed ring 66 is fixedly connected to the bottom of the sliding rod 68, and the fixed ring 66 is limited by the connecting bracket 5.

[0020] When the conduit is needed, the connecting bracket 5, fixing cylinder 61, pull plate 62, guide rod 63, compression spring 64, piston plate 65, fixing ring 66, sliding groove 67, and sliding rod 68 work together to pull the pull plate 62, causing the piston plate 65 to move upwards, thus moving the two sets of fixing rings 66 away from each other. After the item is placed, the pull plate 62 is released, and the two sets of fixing rings 66 secure the item, ensuring that the item connected to the conduit is always inside the fixing rings 66. This solves the problem of the item connected to the conduit falling off the fixing bracket when the bracket shakes. In this embodiment, when the pull plate 62 is pulled upward, it moves upward along with the guide rod 63 and the piston plate 65, thereby causing the sliding rod 68 and the upper fixing ring 66 to move upward, so that the two sets of fixing rings 66 move away from each other, and the item connected to the conduit is placed on the fixing ring 66. At this time, the pull plate 62 is released, and the compression spring 64, which is in a compressed state, generates elastic force to drive the piston plate 65 to return downward, thereby driving the guide rod 63 to return to the bottom of the inner wall of the fixing cylinder 61, and allowing the pull plate 62 to return to the fixing cylinder 61, so that the pull plate 62 is in contact with the top of the fixing cylinder 61, thereby causing the sliding rod 68 and the upper fixing ring 66 to move downward together, so that the two sets of fixing rings 66 move closer to each other, and fix the item placed on the fixing ring 66.

[0021] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the support device includes a limiting plate 71, a sliding block 72, a tension spring 73, a fixing block 74, a moving block 75, a compression spring 76, a rack 77, a gear 78, a support column 79, a flipping plate 710, a compression block 711, a compression spring 712, a locking block 713, and a limiting spring 714. The bottom of the limiting plate 71 is fixedly connected to the top of the support block 3, the top of the sliding block 72 is slidably connected to the inner wall of the base 1, and the bottom of the sliding block 72 is in contact with the top of the support block 3. One end of the tension spring 73 is fixedly connected to the outer wall of the sliding block 72, and the other end is fixedly connected to the outer wall of the limiting plate 71. The bottom of the fixing block 74 is fixedly connected to the inner wall of the base 1. The outer wall of the moving block 75 is slidably connected to the inner wall of the base 1, and the side of the moving block 75 is in contact with the sliding block 72. One end of the compression spring 76 is fixedly connected to the bottom of the moving block 75, and the other end is fixedly connected to the top of the fixing block 74, and the compression spring 76 is connected to the sliding block 75. The movable block 72 limits the movement of the movable block 75. The outer wall of the rack 77 is fixedly connected to the outer wall of the movable block 75. The outer walls of both ends of the support column 79 are fixedly connected to the inner wall of the base 1. The inner wall of the flip plate 710 is rotatably connected to the outer wall of the support column 79. The inner wall of the gear 78 is rotatably connected to the outer wall of the support column 79. The outer wall of the gear 78 is fixedly connected to the outer wall of the flip plate 710, and the teeth of the gear 78 mesh with the teeth of the rack 77. The outer wall of the pressing block 711 is slidably connected to the base 1. The inner wall of the base 1 is fixedly connected to the outer wall of the pressing block 711 by the moving block 75. One end of the pressing spring 712 is fixedly connected to the outer wall of the pressing block 711, and the other end is fixedly connected to the inner wall of the base 1. The outer wall of the locking block 713 is slidably connected to the inner wall of the base 1, and the locking block 713 is in contact with the slot on the flip plate 710. The pressing block 711 limits the locking block 713. One end of the limiting spring 714 is fixedly connected to the outer wall of the locking block 713, and the other end is fixedly connected to the inner wall of the base 1.

[0022] When the fixed frame wobbles and tilts to one side, the base 1, limit plate 71, sliding block 72, tension spring 73, fixed block 74, moving block 75, compression spring 76, rack 77, gear 78, support column 79, and flip plate 710 work together to make the sliding block 72 slide to one side when the fixed frame tilts to one side. This causes the sliding block 72 to press against the moving block 75, which moves downward and drives the rack 77 to move downward. The meshing rack 77 drives the gear 78 to rotate, which in turn causes the flip plate 710 to flip outward and contact the ground. This solves the problem of the fixed frame completely tipping over when it tilts to one side. When the fixed frame wobbles and the tilt is slight, the base 1, moving block 75, compression spring 1 76, flip plate 710, compression block 711, compression spring 2 712, locking block 713, and limiting spring 714 work together to ensure that the flip plate 710 remains on the inner wall of the base 1 until the moving block 75 fully compresses the compression block 711. At this point, the locking block 713 stops limiting the flip plate 710, and the flip plate 710 flips outward. This solves the problem of the flip plate 710 flipping outward even when the fixed frame wobbles slightly, which would increase the probability of the fixed frame accidentally touching a person.

[0023] It also includes a pressing device to prevent the fixing frame from tilting to one side and becoming irreversible. The inner wall of the base 1 is provided with a pressing device, which includes a sleeve 81, a tension block 82, a moving spring 83, an L-shaped connecting rod 84, a connecting rod 85, a return spring 86, a support rod 87, a rotating plate 88, and a load-bearing block 89. The outer wall of the sleeve 81 is fixedly connected to the outer wall of the sliding block 72, the outer wall of the tension block 82 is slidably connected to the inner wall of the sleeve 81, one end of the moving spring 83 is fixedly connected to the inner wall of the sleeve 81, and the other end is fixedly connected to the outer wall of the tension block 82. The bottom of the support rod 87 is fixedly connected to the base 1. The inner wall of the rotating plate 88 is rotatably connected to the outer wall of the support rod 87. The bottom of the load-bearing block 89 is fixedly connected to the inner wall of the rotating plate 88. The top of the L-shaped connecting rod 84 is fixedly connected to the bottom of the tension block 82, and one end of the bottom of the L-shaped connecting rod 84 is in contact with the outer wall of the rotating plate 88. The outer wall of the connecting rod 85 is slidably connected to the inner wall of the L-shaped connecting rod 84, and the outer wall of the connecting rod 85 is slidably connected to the outer wall of the rotating plate 88, thereby limiting the rotation plate 88. One end of the return spring 86 is fixedly connected to the outer wall of the connecting rod 85, and the other end is fixedly connected to the inner wall of the L-shaped connecting rod 84.

[0024] When the fixed frame tilts to one side, the sliding block 72, sleeve 81, tension block 82, moving spring 83, L-shaped connecting rod 84, connecting rod 85, return spring 86, support rod 87, rotating plate 88, and load-bearing block 89 work together to move the sliding block 72 to one side, causing the sleeve 81 to move to one side as well. This causes the L-shaped connecting rod 84 to move the load-bearing block 89 on the rotating plate 88 in the opposite direction of the tilt. As a result, the weight on the tilted side is greater than that on the tilted side, which solves the problem that the fixed frame cannot be restored after tilting and causes the fixed frame to move with the guide tube.

[0025] In this embodiment, when the fixing frame tilts to one side, the sliding block 72 slides to the tilted side, pressing the inclined surface of the moving block 75. This causes the moving block 75 to move downwards along the inner wall of the base 1, driving the rack 77 to move downwards as well. The rack 77 then drives the gear 78 to rotate counterclockwise along the support column 79, causing the gear 78 to rotate the flip plate 710, gradually moving it away from the base 1. Simultaneously, when the sliding block 72 presses against the inclined surface of the moving block 75, the moving block 75 presses downwards against the inclined surface of the pressing block 711, causing the pressing block 711 to move towards the inner wall of the base 1. This allows the pressing block 711 to press against the inclined surface of the locking block 713, gradually moving the locking block 713 away from the slot of the flip plate 710, releasing the restriction on the flip plate 710. When the fixing... When the frame is reset to the other side, the tension spring 73 generates elastic force to drive the sliding block 72 to gradually move away from the moving block 75. At this time, the compression spring 76, which is in a compressed state, generates elastic force to drive the moving block 75 to reset upward, causing the rack 77 to move upward, thereby driving the gear 78 to rotate clockwise, allowing the flip plate 710 to reset towards the inner wall of the base 1. At the same time, after the moving block 75 moves upward, it no longer compresses the compression block 711. The compression spring 712, which is in a compressed state, generates elastic force to drive the compression block 711 to reset towards the center of the base 1. The compression block 711 no longer compresses the locking block 713. The limit spring 714, which is in a compressed state, generates elastic force to drive the locking block 713 to reset towards the flip plate 710, so that the locking block 713 is re-locked into the slot of the flip plate 710, thus limiting and fixing the flip plate 710.

[0026] When the sliding block 72 slides to the tilted side, it drives the sleeve 81 to move to that side as well. The tension block 82 inside the sleeve 81 remains connected to the L-shaped connecting rod 84 under the action of the moving spring 83. The L-shaped connecting rod 84 moves with the sleeve 81. The bottom end of the L-shaped connecting rod 84 pushes the rotating plate 88 to rotate in the opposite direction of the tilt along the support rod 87, causing the load-bearing block 89 on the rotating plate 88 to move to the tilted side, increasing the weight on the tilted side and helping the fixing frame to return to the horizontal position. When the fixing frame returns to its original position, the sliding block 72 returns to its original position under the action of the tension spring 73, driving the sleeve 81 and the L-shaped connecting rod 84 back to their initial positions. At the same time, the rotating plate 88 also returns to its initial state under the combined action of the weight of the load-bearing block 89 and the return spring 86.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
