[0021] In order to have a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific embodiments of the present utility model will now be described with reference to the accompanying drawings. Among them, the same components are denoted by the same reference numerals.

[0022] As Figures 1-4 described, the present utility model provides a surgical tray rack, which includes a base 2 with rollers 1. A vertical lifting rod 3 is arranged above the base 2, and a pair of support bottom plates 4 are arranged below the base 2. In the illustrated specific embodiment, two rollers 1 corresponding to the position of the support bottom plates 4 are arranged below the base 2. The rollers 1 facilitate the movement of the surgical tray rack, and the support bottom plates 4 are used to support on the ground to prevent tipping, and at the same time can provide sufficient friction when in contact with the ground to prevent the surgical tray rack from moving arbitrarily. The vertical lifting rod 3 can adopt any existing electric lifting rack, such as the bracket of an electric lifting table, etc., or can also adopt the vertical rod with an electric lifting function described in CN 219207872 U.

[0023] Further, a treadle switch 21 for respectively controlling the rising and falling of the vertical lifting rod 3 can also be provided on the base 2. In the illustrated specific embodiment, a treadle switch 21 is provided on each of the left and right sides of the base 2. One of the treadle switches 21 can be selectively used to control the rising of the vertical lifting rod 3, and the other treadle switch 21 can be selectively used to control the falling of the vertical lifting rod 3.

[0024] Further, a power switch 22 and an indicator light 23 can also be provided on the base 2. Pressing the power switch 22 can connect or disconnect the power supply. Two indicator lights 23 are shown in the figure, which can respectively display states such as power connection, voltage shortage, external power connection, and charging.

[0025] Further, an external power socket 24 and a detachable battery 25 can also be provided on the base 2. The detachable battery 25 is convenient for use when the surgical tray holder is moved to any position. The external power socket 24 can be used to connect to the mains for long-term use, and the detachable battery 25 can also be charged through the external power socket 24.

[0026] Further, the surgical tray holder of the present utility model is also provided with a control lever 5 for facilitating the adjustment of the position and orientation of the tray, as shown in the figure. In the illustrated specific embodiment, the top of the vertical lifting rod 3 supports the control lever 5, and the surgical tray 6 is installed at the end of the control lever 5.

[0027] Specifically, a connecting cross bar 31 is installed at the top of the vertical lifting rod 3, and the control lever 5 is supported at the top of the vertical lifting rod 3 through the connecting cross bar 31. Among them, the connecting cross bar 31 has a cross arm 311 connected to the vertical lifting rod 3, and a connecting column 312 for inserting the control lever 5 is provided at the end of the cross arm 311.

[0028] One end of the control lever 5 away from the surgical tray 6 has a threaded handle 51. The threaded end of the handle 51 is installed on a control seat 52. A telescopic rod 53 is provided inside the handle 51. A gear handle 54 for driving the telescopic rod 53 to expand and contract is provided on one side of the control seat 52. The telescopic rod 53 is provided with a rack 531 meshing with the gear 541 of the gear handle 54 (see Figure 4 ). When it is necessary to extend or shorten the telescopic rod 53, the gear handle 54 can be shaken to drive the gear 541 to rotate, thereby driving the rack 531, and then driving the telescopic rod 53 fixedly connected to the rack 531 to move back and forth, so that the position of the tray 6 can be telescopically moved.

[0029] Further, a tray connecting piece 61 is connected to the end of the telescopic rod 53, and the bottom of the tray 6 is connected to the tray connecting piece 61 through a quick-release connecting piece 62. The quick-release connecting piece 62 can adopt the quick-release connecting pieces commonly used in electronic devices such as cameras sold on the existing network. For example, quick-release adapter seats for small photographic auxiliary devices such as cameras, anti-loosening quick-release seats for tripods, quick-switching seats for photographic equipment, quick-release pan-tilt connecting seats for cameras, etc. Those skilled in the art can use the above keywords to search and select suitable quick-release accessories on shopping websites. To assist in the installation of the quick-release connecting piece 62, a welding block 63 whose bottom can be threadedly connected to the quick-release connecting piece 62 can also be welded to the bottom of the tray 6 as needed. By using the quick-release connecting piece 62, the tray 6 of the present utility model can be quickly disassembled and replaced during the operation.

[0030] Further, two lugs 521 are provided at the lower part of the control seat 52, and a clamping shaft 32 inserted into the connecting column 312 is installed between the two lugs 521. The clamping shaft 32 is composed of two semi-cylindrical structures 321, and the connecting column 312 is inserted between the two semi-cylindrical structures 321.

[0031] The control seat 52 has a squeezable gap 522, which extends from the top of the control seat 52 to the upper part of the lug 521. A handle 51 is provided on one side of the gap 522, and a fixing block 55 threadedly connected to the handle 51 is provided on the other side of the gap 522. The gap 522 can be squeezed and closed by the threaded connection between the handle 51 and the fixing block 55.

[0032] Both sides of the gap 522 of the control seat 52 abut against the handle 51 and the fixing block 55 respectively. When the handle 51 is turned, the threaded connection distance between the handle 51 and the fixing block 55 changes. When the distance between the two becomes shorter, the gap 522 will be squeezed and closed, so that the circumferential length of the lug 521 is reduced, and the lug 521 will clamp the clamping shaft 32, so that the control seat 52 cannot be pitched and controlled around the clamping shaft 32. At the same time, as the gap 522 is squeezed and closed, the circumferential length of the lug 521 becomes smaller. The clamping shaft 32 in the lug 521 is not only locked and difficult to pitch, but also the two semi-cylindrical structures 321 of the clamping shaft 32 will clamp the connecting column 312, and the lateral movement of the control rod 5 around the connecting column 312 will also be restricted or even unable to move.

[0033] When it is necessary to control the control rod 5, the handle 51 can be loosened to restore the gap 522 to its original size, and the control rod 5 can be arbitrarily horizontally and longitudinally pitched and controlled, so as to change the position and direction of the tray.

[0034] Further, additional structures such as a resisting block 511 and a resisting ring 512 can be provided between the handle 51 and the fixing block 55 to facilitate the handle 51 to resist against one side of the gap 522 of the fixing block 52.

[0035] Inside the fixing block 55, a clamping sleeve 56 is provided, and the telescopic rod 53 is inserted inside the clamping sleeve 56; on one side of the control seat 5 opposite to the gear handle 54, a locking nut 542 is provided, and the end of the locking nut 542 can pass through the fixing block 55 to resist against the side of the clamping sleeve 56 to lock the telescopic rod 53. When it is necessary to fix the telescopic rod 53 to prevent it from telescopic movement, the locking nut 542 can be tightened to resist against the side of the clamping sleeve 56 to deform it, thereby locking the telescopic rod 53 inside the clamping sleeve 56. Conversely, when the locking nut 542 is loosened, the clamping sleeve 56 restores its original size through its own elastic deformation, and the telescopic rod 53 can move freely in the clamping sleeve 56. At this time, by shaking the gear handle 54, the telescopic rod 53 can be driven to move back and forth through the gear 541.

[0036] Further, a convex structure can be provided inside the clamping sleeve 56 for cooperating with the groove 532 on the telescopic rod 53 to prevent the telescopic rod 53 from rotating arbitrarily.

[0037] Further, at the end of the telescopic rod 53 located inside the handle 51, a limiting sleeve 533 is provided, and the diameter of the limiting sleeve 533 is larger than the inner diameter of the channel through which the fixing block 55 penetrates the telescopic rod 53. By providing the limiting sleeve 533, it can be avoided that when the gear 541 drives the rack 531, the telescopic rod 53 is pushed out from the end of the control rod 5. Once the rack 531 is disengaged from the meshing relationship with the gear 541, it cannot be retracted and controlled anymore.

[0038] Further, the clamping sleeve 56 can be positioned inside the fixing block 55 through a threaded cap 561 threadedly connected to the fixing block 55.

[0039] In summary, the surgical tray rack of the present utility model can not only electrically drive the height of the surgical tray and flexibly move the position of the surgical tray rack, but also adjust the position and orientation of the tray through the control rod, improving the usage range of the surgical tray rack. The user holds the handle 51 and can control the position of the tray 6 by pitching up and down and swaying left and right. The user can also push the telescopic rod 53 to extend and retract by shaking the gear handle 54. Moreover, in the case of needing to lock, the handle 51 can be turned to make the control rod 5 unable to pitch up and down or sway left and right, or the telescopic rod 53 can be independently locked to make it unable to extend and retract.

[0040] Those skilled in the art should understand that although this utility model is described in terms of multiple embodiments, not every embodiment contains only one independent technical solution. This narrative in the specification is merely for clarity. Those skilled in the art should understand the specification as a whole and consider the technical solutions involved in each embodiment as ways that can be combined with each other to form different embodiments to understand the protection scope of this utility model.

[0041] The above is only an illustrative specific implementation manner of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes, modifications, and combinations made by those skilled in the art without departing from the concept and principles of this utility model shall fall within the scope of protection of this utility model.
