[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] See also Figure 1 to Figure 7 A handle adjustment device for a surgical microscope described in a preferred embodiment of the utility model includes a column 1 and a handle 2 matched therewith, and at least one connecting block component 3 is provided between the column 1 and the handle 2. The handle 2 is movably arranged on the column 1 up and down through the connecting block component 3 and is locked in position. The connecting block component 3 includes a connecting block body 4 and an elastic support member 5.

[0027] Preferably, the column body of the column 1 is provided with at least one limiting groove 6 extending from top to bottom along the circumferential direction, the connecting block member 3 is movably arranged in the limiting groove 6 up and down, and the handle 2 is fixedly connected to the connecting block member 3 .

[0028] Preferably, the limiting groove 6 is a T-shaped groove.

[0029] Preferably, an elastic support member installation groove 7 is opened on one end face of the connecting block 4, and the elastic support member 5 is fixedly installed inside by bolts. The other end face of the connecting block 4 has an assembly end 8, which is exposed through the limiting groove 6 and fixedly connected to the handle 2. The connecting block component 3 is abutted against the A-side groove wall of the limiting groove 6 through the elastic support member 5, and the connecting block component 3 is abutted against the B-side groove wall of the limiting groove 6 through the connecting block 4.

[0030] The connecting block 4 can act as an intermediate carrier to indirectly transmit the force to the elastic support member 5 to cause it to be compressed and deformed. At the same time, it can also abut against the limiting groove 6 through the force provided by the elastic support member 5 to play a locking role through friction.

[0031] Preferably, the elastic support member 5 is an arc-shaped spring sheet, and the pins at both ends of the elastic support member 5 have contact arc ends 9 .

[0032] The contact arc end 9 can reduce the resistance of the elastic support member 5 when it moves up and down, making it convenient for medical staff to perform adjustment operations.

[0033] Preferably, there are two connecting blocks 4, which are respectively fixedly connected to the two handle mounting ends 10 of the handle 2, and are threadedly connected to the assembly end 8 by bolts passing through the assembly cavity 11 of the mounting end 10, so that the handle 2 and the connecting block component 3 are fixedly connected.

[0034] Preferably, a cover 12 is fixedly provided on the handle 2 at the assembly cavity 11 .

[0035] The cover 12 can cover the assembly cavity 11, making it easier to sterilize the entire surgical microscope before and after surgery.

[0036] The working principle of the utility model is as follows:

[0037] When the medical staff needs to adjust the height of the handle 2 according to their own height, they can hold the column 1 with one hand to ensure that the surgical microscope body does not move, and hold the handle 2 with the other hand to apply a force in the direction of the column 1. The force is indirectly transmitted to the connecting block 4 through the handle 2, and the connecting block 4 moves in the direction of the column 1. At this time, the elastic support member 5 will receive pressure and then deform. At this time, the B-side groove wall of the connecting block 4 and the limiting groove 6 is separated. The medical staff can pull the handle 2 up and down according to their own height, and the elastic support member 5 contacts the The arc end 9 contacts the A-side groove wall of the limiting groove 6 to reduce the resistance to sliding up and down. When the handle 2 reaches the required position, the medical staff can release the handle 2. At this time, the elastic support member 5 can be reset, driving the connecting block 4 to abut the B-side groove wall of the limiting groove 6, and finally forming a vertical friction force between the connecting block 4, the elastic support member 5 and the limiting groove 6, thereby offsetting the gravity of the connecting block 4, the elastic support member 5 and the handle 2, ensuring that the handle 2 will not fall automatically, and the handle 2 can be fixed in the required position for the medical staff to pull.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
