[0042] In the prior art, the surgical tray and the bracket are reversed by 180 degrees so that the surgical tray corresponds to the middle part of the operating bed, and the medical personnel on both sides can easily obtain medical instruments, but this use also causes the center of gravity of the bracket to be unstable, and the prior art often uses sandbags and other heavy objects to fix the bracket, which increases the workload and also easily causes the bed side to be blocked, affecting the medical personnel to walk.

[0043] Based on the above problems in the prior art, the utility model provides a surgical tray frame capable of preventing tilting, which comprises Figure 1 and Figure 2As shown, the anti-toppling surgical tray rack comprises: a tray body 100; a rack body 200, the rack body 200 comprises a bottom rack 210 and a telescopic rod 220 vertically arranged on one end of the bottom rack 210, a bent portion 222a is arranged on the end of the telescopic rod 220 away from the bottom rack 210, and the tray body 100 is arranged on the bent portion 222a; a storage bin 221c is arranged on one side of the telescopic rod 220, a supporting rod 230 is rotatably arranged in the storage bin 221c, the supporting rod 230 is detachably connected with the storage bin 221c at a predetermined position, and the supporting rod 230 is used for supporting the rack body 200.

[0044] The telescopic rod 220 is arranged on one side of the rack body 200, the rotatable supporting rod 230 is arranged in the storage bin 221c, when the tray body 100 needs to be rotated to correspond to the upper side of the operating bed, the supporting rod 230 can be rotated to the predetermined position to be clamped, thereby forming the support on the ground, the position of the rack body 200 is locked, and the stability of the rack body 200 is improved; the supporting rod 230 occupies a very small space, and the situation that the surgical tray rack is easily tilted due to the change of the gravity center of the surgical tray and the tray is avoided while not affecting the walking of medical staff.

[0045] In the above embodiment, as shown in Figure 1 and Figure 2 The main body of the anti-toppling surgical tray rack of the utility model is composed of a tray body 100 and a rack body 200, wherein the tray body 100 is a surgical tray in the prior art, and the rack body 200 comprises a bottom rack 210 and a telescopic rod 220; the bottom rack 210 is used for stabilizing the whole anti-toppling surgical tray rack, and the telescopic rod 220 has a telescopic function and is used for adjusting the height of the tray body 100, thereby facilitating medical staff to obtain medical instruments in the tray body 100; in the embodiment, a bent portion 222a is arranged on the end of the telescopic rod 220 away from the bottom rack 210, and the bent portion 222a is arranged at a predetermined angle, thereby providing a part for fixing the tray body 100; specifically, the tray body 100 arranged on the bent portion 222a is placed in a horizontal state.

[0046] In the use of the conventional surgical tray rack, the setting direction of the tray body 100 corresponds to the position of the bottom rack 210, and the gravity center is on the bottom rack 210, so that the stability can be ensured; however, when the surgical tray rack is applied to an operating bed, the bottom of the operating bed is filled with adjustable support structures and medical equipment, so that the bottom rack 210 of the conventional surgical tray rack cannot be moved to the bottom of the operating bed, and the tray body 100 needs to be rotated by 180 degrees relative to the bottom rack 210, thereby forming an S-shaped structure as shown in Figure 2 At this time, the gravity center of the tray body 100 does not correspond to the bottom rack 210, and the tray body 100 is easily moved downward due to external force in the use process, thereby causing the whole surgical tray rack to be tilted.

[0047] For this reason, in the case of using the disc body 100 in the reverse direction by 180 degrees when the bottom of the operating bed is filled with other equipment, a storage bin 221c is arranged on one side of the telescopic rod 220 in the embodiment, a supporting rod 230 is arranged in rotation in the storage bin 221c, and the supporting rod 230 can be detachably connected with the storage bin 221c at a predetermined position after rotation, so as to form position fixation. The fixed supporting rod 230 is in abutment with the ground, supports the downward pressing direction of the disc body 100, and thus can assist in stabilizing the chassis 210 and prevent side tilting.

[0048] In the embodiment, the supporting rod 230 is hidden in the storage bin 221c when not in use, and does not affect the normal use of the operating tray frame in other use states. When the supporting rod 230 needs to be opened in the above-mentioned case, the ground is supported, the position of the operating tray frame is locked, the chassis 210 is stabilized, and the side tilting pressure is resisted, so as to improve the stability during use without affecting the placement of the operating tray frame.

[0049] Specifically, as shown in Figure 1 The above-mentioned chassis 210 is specifically composed of a first cross beam 211, a second cross beam 212, and a longitudinal beam 213. The first cross beam 211 and the second cross beam 212 are arranged in parallel, and the longitudinal beam 213 is fixedly connected with the first cross beam 211 and the second cross beam 212, so as to increase the area of the chassis 210 and obtain greater stability. Meanwhile, the space formed between the first cross beam 211, the second cross beam 212, and the longitudinal beam 213 can facilitate the standing position of medical staff.

[0050] In the embodiment, in order to further guarantee the anti-toppling performance of the operating tray frame, as shown in Figure 1 In the embodiment, a plurality of installation grooves 214 are arranged on the upper surfaces of the first cross beam 211 and the second cross beam 212, respectively. The sizes of the installation grooves 214 correspond to each other. In the embodiment, the anti-toppling operating tray frame further includes a plurality of counterweight blocks 300, which are detachably arranged in the installation grooves 214. In actual use, the center of gravity of the chassis 210 can be adjusted by adjusting the installation grooves 214 of the counterweight blocks 300 at different positions, and the side tilting of the disc body 100 under stress can be prevented by the principle of leverage.

[0051] Specifically, as shown in Figure 1As shown, in this embodiment, the longitudinal beam 213 should be set perpendicular to the center line of the length direction of the first crossbeam 211 and the second crossbeam 212, that is, the longitudinal beam 213, the first crossbeam 211, and the second crossbeam 212 form an "I" shape to ensure the center of gravity is concentrated and the chassis is stable. The aforementioned mounting slots 214 are set at both ends of the first crossbeam 211 and the second crossbeam 212. Since the mounting slots 214 are the same size, the counterweights 300 can be placed as needed. In this embodiment, the number of counterweights 300 is specifically two, and the number of mounting slots 214 is specifically four. In actual use, medical personnel can switch the position of the counterweights 300 according to actual needs to improve stability.

[0052] by Figure 2 Taking the state as an example, in addition to using support rods 230 to fix the base frame 210, two counterweights 300 can be placed in the two mounting slots 214 on the second crossbeam 212, so that the overall center of the anti-tipping surgical tray frame is shifted to the position of the corresponding base frame 210; in other embodiments, there is also a case where the tray body 100 rotates 90 degrees relative to the base frame 210. In this case, the two counterweights 300 can be placed in the two storage compartments 221c opposite to the end of the tray body 100, thereby improving the stability of the base frame 210.

[0053] In this embodiment, to facilitate medical staff in adjusting the position of the anti-tipping surgical tray frame or moving and transporting the anti-tipping surgical tray frame, such as... Figure 1 As shown, several casters 400 are provided on one side below the base frame 210. Specifically, the casters 400 are located on the side below the ends of the first crossbeam 211 and the second crossbeam 212. In actual use, they allow for effortless movement. In this embodiment, since only two counterweights 300 are provided, the actual added weight to the base frame 210 is minimal and will not affect the movement of the entire surgical tray frame by the casters 400. Specifically, the height of the casters 400 should correspond to the orthographic projection of the support rod 230 onto the vertical plane below the base frame 210. This ensures that the support rod 230 can maintain close contact with the ground during use, providing both support and braking to prevent displacement due to the casters 400.

[0054] In another possible embodiment of this utility model, such as Figure 1As shown, the telescopic rod 220 is specifically composed of a base rod 221, an adjusting rod 222 and a locking 223.

The other is an adjusting part 221b for realizing the telescopic function in cooperation with the adjusting rod 222. In this embodiment, the pivot arrangement position of the support rod 230 in the storage bin 221c should be below and a certain allowance should be reserved to make the support rod 230 have a proper rotation angle. In actual arrangement, the upper end of the support rod 230 should also be arranged with a pulling mechanism to facilitate the medical staff to pull out the support rod 230. The support rod 230 rotates around the pivot to the below and abuts against the ground. In order to realize the locking of the position of the support rod 230, a tenon 234 is arranged on one side of the functional part 221a in this embodiment. The tenon 234 penetrates through the storage bin 221c. Correspondingly, a hole is arranged on the support rod 230.
