Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0036] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-9 A simple sterile foldable tray for intraoperative use includes two symmetrically arranged mounting plates 1, a foldable tray 2, an extension adjustment and locking assembly 3, and a telescopic cover limiting assembly 4. The foldable tray 2 is positioned between the two mounting plates 1, and flexible plastic is fixed between the front and rear ends of the foldable tray 2 and the side walls of the two mounting plates 1. One end of the telescopic cover limiting assembly 4 is installed on the top of the rear mounting plate 1, and the other end can be snapped onto the top of the front mounting plate 1. The foldable tray 2 can be repeatedly sterilized to achieve a sterile effect, facilitating its use during surgery.

[0037] like Figures 1-8 As shown, the extension adjustment locking assembly 3 includes an extension adjustment assembly 31 and a locking assembly 32. The two ends of the extension adjustment assembly 31 are respectively connected to the bottom of the two mounting plates 1, and the locking assembly 32 is installed on the extension adjustment assembly 31.

[0038] When in use, the extension adjustment component 31 is used to adjust the extension of the folding tray 2. The folding tray 2 is small in size after folding and easy to store. The locking component 32 is used to lock the extension adjustment component 31, thereby maintaining the stability of the folding tray 2.

[0039] like Figure 9As shown, the folding tray 2 consists of multiple small panels, with flexible plastic fixed between adjacent panels. Both the flexible plastic and the small panels are made of PVC.

[0040] When this utility model is in use, the surgical instruments are placed on the folding tray 2, and the instruments on the folding tray 2 are covered and protected by the telescopic covering and limiting component 4.

[0041] In some embodiments, the extension adjustment assembly 31 includes a connecting block 311, a first swing arm 312, and a second swing arm 314. The connecting block 311 is detachably snap-fitted onto the bottom of the rear mounting plate 1. There are two swing arms 312 and two swing arms 314, arranged symmetrically on the left and right. One end of the first swing arm 312 is hinged to the connecting block 311, and the other end of the first swing arm 312 is hinged to one end of the second swing arm 314. The other end of the second swing arm 314 is rotatably connected to the bottom of the front mounting plate 1 via a pivot 315. The locking assembly 32 is connected to both first swing arms 312. The pivot 315 at the other end of the second swing arm 314 can be detached from the bottom of the front mounting plate 1.

[0042] Among them, the outer wall of the two swing arms 312 on the side closest to each other has a storage cavity for storing the second swing arm 314. The upper and lower end faces of the two swing arms 312 on the side closest to each other have a relief groove 313 for avoiding the rotating shaft 315.

[0043] In some embodiments, the locking assembly 32 includes a mounting sleeve 321, a pin 322, a spring 323, a socket 324, a C-shaped locking plate 325, and an ear plate 326. The mounting sleeve 321 is fixedly mounted on the right side wall of the C-shaped locking plate 325. The pin 322 is located inside the mounting sleeve 321. The spring 323 is sleeved on the outside of the pin 322, and one end of the spring 323 is fixedly connected to the inner wall of the mounting sleeve 321, while the other end of the spring 323 is fixedly connected to the pin 322. A socket 324 is provided through the right side wall of the right swing arm 312 for insertion of the pin 322. The left end of the pin 322 can pass through the socket 324 and be inserted into the inside of the right swing arm 312. The right end of the pin 322 slides through and extends to the outside of the right end of the mounting sleeve 321. An ear plate 326 is fixedly mounted on the left side of the C-shaped locking plate 325 for hinged connection with the left side wall of the left swing arm 312.

[0044] Preferably, the length of the center line connecting the hinge points of the two swing arms 312 and the connecting block 311 is greater than the length of the center line connecting the hinge points of the two swing arms 312 and the swing arm 314.

[0045] When this utility model is in use, if the folding tray 2 is in the unfolded state, such as Figures 4-5As shown, when the folding tray 2 needs to be folded and stored, the locking component 32 unlocks the two swing arms 312. At this time, both swing arms 312 can rotate around the connecting block 311. Pulling the two swing arms 312 outwards with both hands causes the two swing arms 314 to move synchronously with the swing arms 312, thereby reducing the distance between the two mounting plates 1. The folding tray 2 folds accordingly. When the included angle of the two swing arms 312 rotates to its maximum, the end of the two swing arms 314 connected to the pivot 315 rotates inwards toward the storage cavity of the swing arm 312 until the pivot 315 moves into the clearance groove 313. At the same time, the swing arms 314 are stored in the storage cavity of the swing arm 312. At this time, the distance between the two mounting plates 1 is the smallest, and the folding of the folding tray 2 is completed.

[0046] In use, the two swing arms 312 are locked by the C-shaped locking plate 325 through the insertion of the pin 322 into the socket 324. When unlocking, the pin 322 is pulled outward, and the pin 322 drives the spring 323 to compress until the pin 322 disengages from the socket 324. The C-shaped locking plate 325 is rotated so that the C-shaped locking plate 325 rotates downward around the ear plate 326 and disengages from the two swing arms 312, so that the two ends of the C-shaped locking plate 325 no longer limit the swing arms 312.

[0047] In some embodiments, such as Figures 1-8 As shown, the telescopic cover limiting assembly 4 includes a telescopic cover assembly 41 and a limiting assembly 42; the telescopic cover assembly 41 is installed on the top of the rear mounting plate 1, and the limiting assembly 42 is installed on the top of the telescopic cover assembly 41 and the front mounting plate 1.

[0048] Specifically, the telescopic cover assembly 41 includes a roller 411, a spiral spring 412, and a cover cloth 413. The two ends of the roller 411 are rotatably connected to the top left and right sides of the rear mounting plate 1, respectively. One end of the spiral spring 412 is fixedly connected to the outer wall of the roller 411, and the other end of the spiral spring 412 is fixedly connected to the top outer wall of the rear mounting plate 1. The inner end of the cover cloth 413 is fixedly wrapped around the outer wall of the roller 411, and the outer end of the cover cloth 413 is snapped into the top of the front mounting plate 1 through the limiting assembly 42.

[0049] The limiting component 42 includes a limiting ring 421 and a limiting pin 422; the limiting ring 421 is fixedly installed on the outer end of the covering cloth 413, and the limiting pin 422 is fixedly installed on the top of the front mounting plate 1. The limiting ring 421 and the limiting pin 422 are used in conjunction with each other.

[0050] In use, the covering cloth 413 is stored by the cooperation of the roller 411 and the spiral spring 412, and the covering cloth 413 is unfolded by the cooperation of the limiting ring 421 and the limiting pin 422.

[0051] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
