The surgical tray can move along the guide rods by sliding connection between the second cross rod 32 and the longitudinal guide rods on the side surface of the operating table so as to adapt to the requirements of different operations on the position of the surgical tray.

In order to make the locking of the vertical bar 2 and the horizontal bar 3 reliable and easy, the first locking unit 23 and the second locking unit 33 respectively include: a locking head 41, a spring 42 and a base 43; the locking head 41 is in supporting connection with the base 43 through a spring 42; the locking head 41 is located in a cavity of the base 43 and is slidable in the base 43.

The first vertical rod 21 and the second vertical rod 22 are of cylindrical structures, and the upper side of the second vertical rod 22 is sleeved inside the first vertical rod 21, so that the first vertical rod 21 and the second vertical rod 22 can slide relatively.

When unlocking is desired, the locking head 41 is pressed in the direction of the base 43, the tip of the locking head 41 is pressed to the outer wall of the second vertical rod 22, and the first vertical rod 21 and the second vertical rod 22 can slide relatively.

The first cross rod 31 and the second cross rod 32 are of cylindrical structures, and one side of the second cross rod 32 is sleeved inside the first cross rod 31; the first rail 31 and the second rail 32 are made slidable relative to each other.

A third locking hole 311 is formed through the outer wall of the first cross rod 31, a fourth locking hole 321 is formed through the outer wall of the second cross rod 32, the base 43 is fixedly connected to the cylindrical inner wall of the second cross rod 32, the locking head 41 is pushed to extend into the third locking hole 311 and the fourth locking hole 321, and the first cross rod 31 and the third locking hole 311 are locked to slide relatively. When unlocking is desired, the locking head 41 is pressed in the direction of the base 43, the tip of the locking head 41 is pressed to the outer wall of the second cross bar 32, and the first cross bar 31 and the second cross bar 32 can slide relatively.

In order to facilitate unlocking of the first locking unit 23 and the second locking unit 33, the surgical tray further includes: the elastic piece 5 is respectively fixed on the outer walls of the first vertical rod 21 and the first cross rod 31 and covers the first locking hole 211 and the third locking hole 311; the top end of the locking head 41 is in a conical structure, and a gap is reserved between the elastic piece 5 and the outer walls of the first vertical rod 21 and the first cross rod 31. When the locking is released, the elastic piece 5 is pressed, the locking head 41 compresses the spring 42 to move towards the inside of the first vertical rod 21 and the first cross rod 31, when the bottommost end of the conical structure at the top end of the locking head 41 is positioned in the inside of the inner walls of the first vertical rod 21 and the first cross rod 31, the first vertical rod 21 and the first cross rod 31 can be pulled, the conical structure at the top end of the locking head 41 is pressed by the first vertical rod 21 and the first cross rod 31, the locking head 41 continues to compress the spring, and the locking head moves towards the direction of the base 43. The locking head 41 is thus pressed into the first vertical bar 21 and the first transverse bar 31, and the first vertical bar 21 and the first transverse bar 31 are movable relative to the second vertical bar 22 and the second transverse bar 32.

In order to prevent the first vertical bar 21 and the second vertical bar 22 from being separated, the top ends of the locking heads 41 of the two first locking units 23 at two ends are in a slope shape, namely, the top ends of the uppermost locking head 41 and the lowermost locking head 41 are in a slope shape, and the slope is arranged at one side far from the first locking units 23; when the first locking hole 211 moves to the uppermost locking head 41, the first vertical rod 21 can only move downwards but not upwards under the action of the slope when the elastic piece 5 is pressed down, so that the first vertical rod 21 and the second vertical rod 22 are prevented from being separated. When the first locking hole 211 moves to the lowermost locking head 41, the first vertical rod 21 can only move upwards and not move downwards under the action of the slope when the elastic piece 5 is pressed down, so that the relative movement range of the first vertical rod 21 and the second vertical rod 22 is limited.

In order to prevent the restriction of the relative movement position of the first rail 31 and the second rail 32, the tips of the locking heads 41 of the two second locking units 33 at both ends of the plurality of second locking units 33 are sloped, and the slope is provided at a side away from the second locking units 33. When the third locking hole 311 moves to the locking head 41 nearest to the slider 35, the first cross bar 31 can only move away from the slider 35 and can not move reversely under the action of the slope when the elastic piece 5 is pressed down. When the third locking hole 311 moves to the locking head 41 farthest from the sliding block 35, under the action of the slope, the first cross bar 31 can only move to the direction close to the sliding block 35 and can not move reversely when the elastic piece 5 is pressed down; this limits the relative movement position of the first rail 31 and the second rail 32.

In order to facilitate the operation of the elastic piece 5, one end of the elastic piece 5 is fixed on the outer wall of the first cross bar 31 or the first vertical bar 21, a distance is reserved between the other end of the elastic piece 5 and the outer wall of the first cross bar 31 or the first vertical bar 21, and the elastic piece 5 is provided with a pressing protrusion 51 at a position covering the first locking hole 211 and the third locking hole 311. When the elastic piece 5 is pressed again, the projection 51 can be pressed against the locking head 41.

The elastic ring 7 limits the second vertical rod 22 to slide relative to the axis of the rotating unit 34. When the elastic ring 7 is installed, the elastic ring 7 is sleeved in the clamping groove on the second vertical rod 22, then the second vertical rod 22 is pressed into the rotating unit 34 forcefully, the elastic ring 7 can be elastically deformed in the process, and the elastic ring 7 enters the clamping groove of the rotating unit 34. At this time, due to the elastic ring 7, the rotating unit 34 is sleeved with the second vertical rod 22, and only if the elastic ring 7 is elastically deformed, the rotating unit 34 and the second vertical rod 22 can be separated.

The crossbar 3 further comprises: the sliding block 35 and the compressing unit 36, the sliding block 35 is fixed at one end of the second cross bar 32 far away from the first cross bar 31, the sliding block 35 is provided with a notch 351, the notch 351 is in sliding connection with a longitudinal guide rod on the side surface of the operating table to be connected, and the operating tray can move along the guide rod. The compressing unit 36 is in threaded connection with the sliding block 35, and the compressing unit 36 can compress the longitudinal guide rod at the side of the operating table. The compression unit enables the operation tray to be fixed on a longitudinal guide rod at the side surface of the operation table.

In order to enable the surgical tray to avoid the cross bar for fixing the guide rod when the longitudinal guide rod at the side surface of the operating table moves, the notch 351 is T-shaped.

The pressing unit 36 includes a pressing unit body 361, a handle 362, the pressing unit body 361 being screw-coupled to the slider 35, the handle 362 being hinged to the pressing unit body 361. When the handle 362 is used to rotate the longitudinal guide bar for compressing/relaxing the lateral surface of the operating table, the handle 362 is rotated to the position of the cross bar 3 to interfere with the cross bar 3 due to space limitation, and at this time, the handle 362 is rotated 180 degrees along the hinge position to continue rotating the longitudinal guide bar for compressing/relaxing the lateral surface of the operating table.

The above is only a preferred embodiment of the present utility model, and is not intended to limit the scope of the present utility model.
