Description

Technical Field

[0001] The present invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a dual-mode gas cylinder safety management system. Background Art

[0002] Laparoscopic surgery requires continuous infusion of carbon dioxide gas to create artificial pneumoperitoneum to provide sufficient operating space. Laparoscopic surgery requires the injection of carbon dioxide into the abdominal cavity to create pneumoperitoneum and create a clear surgical field of view. As a gas source carrier, the stability of the carbon dioxide cylinder directly affects the maintenance of pneumoperitoneum pressure (usually maintained at 12-15 mmHg). If the cylinder tips over or leaks, it may lead to risks such as surgical interruption and gas embolism.

[0003] In the actual application scenarios of laparoscopic surgery, existing carbon dioxide cylinders have exposed significant shortcomings in their use. First, the cylinder itself is heavy, and a single cylinder can reach up to one hundred kilograms when fully filled. This makes it extremely inconvenient for medical staff to operate during transportation, and there is also a high consumption of manpower and the risk of accidental bumps. Secondly, after the cylinder is installed on the surgical frame, due to the limitations of existing fixing technology, it is difficult to firmly restrain the cylinder during surgery. During the operation, the external force generated by frequent equipment movement, body position adjustment and other operations can easily cause the cylinder to shake, and even topple over in severe cases. Once this happens, it may not only cause damage to the cylinder valve and cause gas leakage, interfere with the stable control of pneumoperitoneum pressure, affect the surgical field of view and operating space, but also cause chain reactions such as damage to surgical instruments and power failure of equipment, thereby significantly increasing the risk of surgery, seriously interfering with the normal progress of laparoscopic surgery, and even threatening the patient's life.

Unscrewing connection; the bottom of the gas cylinder fixing frame 2 is provided with a bottom fixing structure 4 for fixing the bottom of the gas cylinder, and the side wall of the gas cylinder fixing frame 2 is provided with a fixing adjustment structure 5, which is slidably matched with the gas cylinder fixing frame 2, and the fixing adjustment structure 5 is provided with a limiting fixing structure 6 for fixing the body of the gas cylinder, and the bottom of the gas cylinder fixing frame 2 is provided with four auxiliary rotating wheels 20; the auxiliary rotating wheels 20 can assist the movement of the gas cylinder fixing frame 2 and also support the entire gas cylinder fixing frame 2.

[0035] Usage method 1:

[0036] The gas cylinder on the gas cylinder fixing frame 2 is connected to the laparoscopic trolley 1, and the position of the gas cylinder can be moved and adjusted according to the needs of the operation through the laparoscopic trolley 1;

[0037] Method 2:

[0038] The gas cylinder fixing frame 2 is disassembled from the laparoscope trolley 1 so that the gas cylinder fixing frame 2 is positioned alone at the surgical site for use.

[0039] Specifically, the bottom fixing structure 4 includes a first fixing seat 41, a second fixing seat 42, an adjustment bidirectional screw shaft 43 and a turntable 44. The first fixing seat 41 and the second fixing seat 42 are provided with fixed semicircular grooves, and the bottom ends of the first fixing seat 41 and the second fixing seat 42 are provided with slide rails 45. The bottoms of the first fixing seat 41 and the second fixing seat 42 are provided with support plates 46. The adjustment bidirectional screw shaft 43 is rotatably connected to the bottom of the gas cylinder fixing frame 2, and the two support plates 46 are threadedly connected to the adjustment bidirectional screw shaft 43; the gas cylinder fixing frame 2 is provided with a slideway 21 that slides with the slide rail 45, and the side wall of the gas cylinder fixing frame 2 is provided with a support groove 22 that slides with the support plate 46, and the turntable 44 is located at the end position of the adjustment bidirectional screw shaft 43.

[0040] When fixing the bottom position of the gas cylinder, the rotating turntable 44 drives the adjustment bidirectional screw shaft 43 to rotate, and the adjustment bidirectional screw shaft 43 rotates to drive the positions of the two support plates 46 to move closer to each other, thereby driving the first fixing seat 41 and the second fixing seat 42 to move in the slideway 21 through the bottom slide rail 45, so that the positions of the two first fixing seats 41 and the second fixing seats 42 are close to each other, and the bottom of the gas cylinder is clamped and fixed, which can quickly and accurately adapt to gas cylinders of different diameters and effectively avoid the risk of gas cylinders tipping over due to vibration or external force

[0041] Specifically, the fixed adjustment structure 5 includes a connecting belt 51 and two adjusting members 52. The two adjusting members 52 are symmetrically arranged inside the gas cylinder fixing frame 2. Each adjusting member 52 includes an upper pulley 521, a lower pulley 522, a connecting belt 523 and an adjusting slider seat 524. The upper pulley 521 and the lower pulley 522 are rotated up and down and connected to the side wall of the gas cylinder fixing frame 2. The connecting belt 523 is sleeved between the upper pulley 521 and the lower pulley 522. The adjusting slider seat 524 It is slidably connected to the side wall of the gas cylinder fixing frame 2, and the adjustment slider seat 524 is connected to the connecting belt 523. The connecting belt 51 is sleeved on two upper pulleys 521, and one of the upper pulleys 521 is provided with a rotating hand plate 525; the side wall of the adjustment slider seat 524 is provided with a locking plate 526, and the locking plate 526 is provided with a locking threaded button 527. The side wall of the gas cylinder fixing frame 2 is provided with locking screw holes 23 distributed vertically and evenly spaced, and the locking threaded button 527 is threadedly connected to the locking screw hole 23.

[0042] When fixing the position of the gas cylinder body, the height position of the limit fixing structure 6 can be adjusted according to the height size of the gas cylinder. At this time, the rotating hand plate 525 can be turned to drive the upper pulley 521 to rotate, and the upper pulley 521 rotates and drives the lower pulley 522 to rotate through the connecting belt 523. The rotation of the connecting belt 523 will drive the adjustment slider seat 524 to slide up and down on the gas cylinder fixing frame 2. The position height of the left fixed semicircular seat 61 and the right fixed semicircular seat 62 can be adjusted according to the height of the gas cylinder, so as to be suitable for the fixation of gas cylinders of different sizes. Whether it is a conventional 40L standard gas cylinder or a small portable gas cylinder, this structure can quickly match its height size, which greatly improves the versatility of the fixing device.

[0043] When the positions of the left fixed semicircular seat 61 and the right fixed semicircular seat 62 are fixed, tighten the locking threaded button 527 so that the locking threaded button 527 is connected to the corresponding locking screw hole 23, thereby locking and fixing the position of the adjustment slider seat 524, thereby locking and fixing the positions of the left fixed semicircular seat 61 and the right fixed semicircular seat 62.

[0044] Specifically, the limiting fixing structure 6 includes a left fixed semicircular seat 61, a right fixed semicircular seat 62 and two plug-in blocks 63. The left fixed semicircular seat 61 and the right fixed semicircular seat 62 are each provided with two sliding blocks 64. The side wall of the adjusting slider seat 524 is provided with a sliding groove that slides with the sliding block 64. The top of the adjusting slider seat 524 is provided with two vertically arranged plug-in rods 65. The plug-in rods 65 slide up and down between the sliding block 64 and the sliding groove. The setting of the plug-in rods 65 ensures that the left fixed semicircular seat 61 and the right fixed semicircular seat 62 are fixed. After the fixed semicircular seat 62 fixes the gas cylinder, the left fixed semicircular seat 61 and the right fixed semicircular seat 62 can be placed on the adjustment slider seat 524 to slide, and the plug-in rod 65 is used to fix the sliding block 64 on the adjustment slider seat 524; the two plug-in blocks 63 are symmetrically arranged on the left fixed semicircular seat 61, and the right fixed semicircular seat 62 is provided with a plug-in groove that is plugged into the plug-in block 63, and each of the plug-in blocks 63 is provided with a fixing threaded button 66 for fixing the left fixed semicircular seat 61 and the right fixed semicircular seat 62.

[0045] When fixing the body of the gas cylinder, the left fixed semicircular seat 61 and the right fixed semicircular seat 62 are respectively slid on the adjustment slider seat 524 through the two plug-in blocks 63, so that the left fixed semicircular seat 61 and the right fixed semicircular seat 62 are close to each other to fix the body of the gas cylinder. When the left fixed semicircular seat 61 and the right fixed semicircular seat 62 are close to each other, the two plug-in blocks 63 are respectively inserted into the two plug-in slots, and then the positions of the left fixed semicircular seat 61 and the right fixed semicircular seat 62 are fixed by rotating the fixing threaded button 66. Fixing the gas cylinder by the left fixed semicircular seat 61 and the right fixed semicircular seat 62 effectively avoids the risk of loosening due to vibration or external force during the operation, and provides reliable safety protection for laparoscopic surgery.

[0046] When operating the gas cylinder, the bottom of the gas cylinder can be clamped and fixed, and the position of the gas cylinder body can be adjusted according to the height of the gas cylinder. The benefits of managing the gas cylinder during laparoscopic surgery are:

[0047] Comprehensive stability ensures reduced surgical risk: The bottom clamp, secured by a bidirectional screw and slide rail 45, provides strong horizontal restraint to the cylinder, preventing it from tipping over due to external impact or trolley movement. The height-adjustable limiter 6 on the cylinder body adjusts the clamping position according to cylinder specifications, providing stable vertical support. This dual securing mechanism ensures the cylinder remains secure throughout surgery, preventing accidents such as gas leaks and line disconnection caused by cylinder movement, minimizing the risk of surgical interruption and ensuring patient safety.

[0048] Flexible adaptation to different gas cylinders, enhancing versatility: The bottom clamping device can adaptively adjust the spacing via a screw drive, accommodating cylinder diameters of various sizes, ranging from 20L to 50L. The cylinder mounting structure can be freely adjusted in height within a range of 600-1200mm. This design allows the same mounting system to accommodate different brands and sizes of gas cylinders, reducing the number of operating room equipment and improving resource utilization. This is especially true when performing multiple surgeries, as cylinder specifications can be quickly switched, saving equipment replacement time.

[0049] Specifically, four sliders 24 are provided on the side wall of the gas cylinder fixing frame 2, and four long slide grooves 13 are provided on the side wall of the laparoscopic trolley 1. The sliders 24 slide up and down in the long slide grooves 13.

[0050] It should be noted that the latch 14 is provided with a safety. When the latch 14 is inserted so that the slider 24 is fixed in the long slide groove 13, a vertical pin is provided at the other end of the latch 14 to prevent the latch 14 from falling off.

[0051] When the gas cylinder is transported to the gas cylinder fixing rack 2 and the gas cylinder fixing rack 2 is on the ground, the pin 14 at the bottom is plugged into the slider 24 and the long slide groove 13. When the gas cylinder fixing rack 2 needs to be hung on the laparoscope trolley 1 when moving upward, the pin 14 at the bottom is pulled out to make the slider 24 move upward in the long slide groove 13. After moving to the specified position, the pin 14 at the top is plugged into the slider 24 and the long slide groove 13, thereby fixing the position of the gas cylinder fixing rack 2 and hanging it on the laparoscope trolley 1.

[0052] Specifically, a rotatably connected connecting plate 31 is provided at the telescopic end of the hydraulic jack 3, two rotating plates 32 are provided on the top of the connecting plate 31, a connecting block 25 is provided on the rear side wall of the gas cylinder fixing frame 2, a circular groove 26 is provided at the bottom of the connecting block 25, and a rotating groove for the rotating plate 32 to move is provided on the side wall of the circular groove 26, and four rotating blocks 33 are provided at the bottom of the connecting plate 31.

[0053] When placing the gas cylinder fixing frame 2 on the laparoscope trolley 1 or removing the gas cylinder fixing frame 2 from the laparoscope trolley 1, the gas cylinder fixing frame 2 needs to be manually moved downward or downward at this time, so that the gas cylinder fixing frame 2 slides in the long slide groove 13 through the corresponding slider 24, so that the position of the gas cylinder fixing frame 2 moves up and down on the laparoscope trolley 1, which is convenient for carrying, moving, installing or removing the gas cylinder fixing frame 2. During this process, the bottom fixing structure 4 and the limit fixing structure 6 work to fix the position of the gas cylinder;

[0054] When the gas cylinder holder 2 needs to be removed from the laparoscopic trolley 1, the four rotating blocks 33 on the connecting plate 31 are rotated to make the connecting plate 31 rotate in the circular groove 26, so that the positions of the two rotating plates 32 on the connecting plate 31 are aligned with the two rotating grooves. The gas cylinder holder 2 is moved upward to remove the connecting block 25 from the connecting plate 31 on the hydraulic jack 3, thereby removing the gas cylinder holder 2;

[0055] It should be noted that when the gas cylinder fixing frame 2 is fixed to the laparoscope trolley 1, the connecting plate 31 is clamped in the circular groove 26 in the connecting block 25 through two rotating plates 32, so that the position of the connecting plate 31 is connected in the connecting block 25. When the hydraulic jack 3 is upward or downward at the telescopic end, it can drive the position of the gas cylinder fixing frame 2 to move upward or downward on the laparoscope trolley 1.

[0056] Specifically, both ends of the laparoscopic trolley 1 are provided with plug-in connectors 7 for fixing the gas cylinder fixing frame 2. Each of the plug-in connectors 7 includes a plug-in round rod 71, a resistance spring 72 and a shift block 73.
