[0021] Please see Figure 1-5 A surgical instrument trolley includes a support frame 1, a lifting frame 4 mounted on the support frame 1, and a placement plate 7 mounted on the lifting frame 4. The support frame 1 is equipped with casters 2 on its bottom surface. A lifting mechanism is provided between the support frame 1 and the lifting frame 4. The lifting mechanism includes a lifting rod 3 mounted on the support frame 1, a guide assembly mounted on the lifting frame 4 that can move along the lifting rod 3, and a locking assembly mounted on the support frame 1. The lifting mechanism drives the placement plate 7 to rise and fall along the lifting rod 3 via the guide assembly, and then locks the position of the lifting frame 4 via the locking assembly, thereby adjusting the height of the medical instruments placed on the placement plate 7.

[0022] The placement plate 7 is used to place surgical instruments. With the help of the lifting mechanism, the height of the placement plate 7 can be adjusted at any time according to the height of doctors, so as to meet the requirements of doctors.

[0023] The present invention is further configured such that the guide assembly includes a mounting plate 5 disposed on the lifting frame 4, a guide wheel 6 disposed on the mounting plate 5, and a V-shaped groove provided on the outer surface of the guide wheel 6, the V-shaped groove being able to be engaged with the outer surface of the lifting rod 3.

[0024] The present invention is further configured such that the locking assembly includes a connector 8 disposed on the support frame 1, a fixing sleeve 9 fitted onto the lifting rod 3 within the connector 8, a movable groove 10 on the fixing sleeve 9, and a clamping assembly disposed within the movable groove 10. The clamping assembly includes a push rod 12, a locking block 11 disposed on one side of the push rod 12, a pressure block 13 disposed on the other side of the push rod 12, a first spring 18 disposed on the push rod 12 between the locking block 11 and the pressure block 13, a boss disposed on the outside of the movable groove 10, the pressure block 13 being movablely locked on the outside of the boss, and a fixing groove 17 disposed on the outer surface of the lifting rod 3. When the locking assembly is locked, the locking block 11 is inserted into the fixing groove 17.

[0025] When it is necessary to release the locking state to adjust the height of the lifting frame 4, simply pull the pressure block 13 outward. At this time, the locking block 11 will exit the fixing groove 17, so that the height of the lifting frame 4 can be adjusted up and down.

[0026] The present invention is further configured such that a locking groove 14 is provided at the lower end of the locking block 11, and a backstop structure is connected at the lower end of the fixing sleeve 9. The backstop structure includes a locking sleeve 15, and protruding plates 20 are provided at intervals above the locking sleeve 15. When the protruding plates 20 are engaged in the locking groove 14, the locking block 11 cannot be withdrawn. When the interval between the protruding plates 20 is engaged in the locking groove 14, the locking block 11 can be withdrawn.

[0027] This is equivalent to locking the locking component, preventing the pressure block 13 from being easily pulled outwards.

[0028] The present invention is further configured such that the anti-retraction structure includes a clamping sleeve 24, a second spring 26 connected between the clamping sleeve 24 and the fixed sleeve 9, a rotating sleeve 19 fitted on the outside of the clamping sleeve 24, and a locking sleeve 15 installed on the inside of the rotating sleeve 19.

[0029] In this way, under the tension of the second spring 26, the upper surface of the protrusion 20 can contact the locking groove 14 without falling down.

[0030] The present invention is further configured such that a protrusion 27 is provided on the outer side of the clamping sleeve 24, and the rotating sleeve 19 is movably installed in the protrusion; a slide 25 is provided on the outer wall of the fixed sleeve 9, and a matching guide groove is provided on the clamping sleeve 24; and a handle 16 is installed on the support frame 1.

[0031] In this way, the rotating sleeve 19 can rotate within the protrusion 27, thereby driving the protruding plate 20 to rotate. A slide bar 25 is provided on the outer wall of the fixed sleeve 9 to serve as a guide, similar to a guide rail.

[0032] In use, the operator slides the lifting frame 4 up and down along the lifting rod 3 to adjust the height of the placement plate 7. The sliding connection between the guide wheel 6 and the lifting rod 3 ensures the stability and accuracy of the lifting process. When it is necessary to fix the position of the lifting frame 4, the multiple sets of locking blocks 11 are moved to the position of the fixing groove 17, and the pressure block 13 is released. Under the pressure of the first spring 18, the locking block 11 slides along the movable groove 10 and then locks into the fixing groove 17. At this time, the operator rotates the sleeve 19 to drive the locking sleeve 15 to rotate, which drives the multiple sets of protruding plates 20 into the locking groove 14 set on the bottom surface of the multiple sets of locking blocks 11 to achieve locking. When unlocking, the rotating sleeve 19 is rotated in the opposite direction to drive the locking sleeve 15 to rotate, so that the multiple sets of protruding plates disengage from the locking groove 14 and release the fixing of the multiple sets of locking blocks 11.

[0033] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
