For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0027] like Figure 1-4 As shown, a thoracic surgery positioning device proposed by the utility model comprises a positioning frame 1, a movable plate 2 is slidably installed in the positioning frame 1, a placement table 3 for placing a puncture needle is provided on the movable plate 2, slide grooves 101 are opened on both sides of the positioning frame 1, a screw rod is rotatably installed in the slide groove 101, a slider 201 is slidably installed in the slide groove 101, the slider 201 is threadedly connected to the screw rod, a control motor for controlling the rotation of the screw rod is provided on one side of the positioning frame 1, and the control motor is started to drive the screw rod to rotate, so that the slider 201 moves in the slide groove 101, and drives the movable plate 2 to move in the positioning frame 1, thereby realizing the adjustment of the position of the placement table 3.

[0028] In this embodiment, the lifting device includes multiple groups of fixed boxes 4, each of which has a moving part 5 slidably installed in it, and the positioning frame 1 is fixedly installed on the top of the moving part 5. The lifting device also includes a screw 8 rotatably installed in the fixed box 4. The shape of the moving part 5 is set to be a U-shaped plate. The moving part 5 is threadedly connected to the screw 8, and a first bevel gear 9 is fixedly installed at the bottom of the screw 8.

[0029] Among them, the lifting device also includes a second bevel gear 10 rotatably installed in the fixed box 4 and meshing with the first bevel gear 9. A fixed seat 15 is provided on the side of the second bevel gear 10 close to the sliding frame 12. When the second bevel gear 10 rotates, the first bevel gear 9 also rotates, thereby driving the screw 8 to rotate, so that the moving part 5 is lifted and lowered in the fixed box 4, thereby realizing the lifting and lowering of the positioning frame 1 fixedly installed on the moving part 5.

[0030] In this embodiment, a fixing component for fixing the positioning frame 1 on both sides of the bed is provided on one side of the lifting device, the fixing component includes a clamping plate 6 slidably installed on the inner side of the fixing box 4, and a handle 7 for controlling the movement of the moving member 5 and the clamping plate 6 is provided on one side of the fixing box 4. The fixing component also includes a sliding frame 12 slidably installed in the fixing box 4, and a rectangular plate 121 is fixedly installed on the side of the sliding frame 12 close to the clamping plate 6, and two groups of moving rods 11 are fixedly installed on the side of the rectangular plate 121 close to the clamping plate 6. The moving rod 11 passes through one end of the fixing box 4 and is fixedly connected to the clamping plate 6. Pulling the handle 7 causes the rectangular block 13 to move, thereby driving the sliding frame 12 to slide in the fixing box 4. At this time, the rectangular plate 121 fixedly installed on one side of the sliding frame 12 also moves, causing the moving rod 11 to move, driving the clamping plate 6 to clamp the rod body at the bottom of both sides of the bed, thereby achieving the fixed installation of the positioning frame 1 on the bed.

[0031] Among them, a rectangular block 13 is slidably installed in the sliding frame 12, and convex blocks are provided on both sides of the bottom of the sliding frame 12. A limit plate 131 is fixedly installed on the bottom of the rectangular block 13. A control rod 14 is rotatably installed at one end of the rectangular block 13 away from the sliding frame 12. The handle 7 is fixedly installed at one end of the control rod 14 that passes through the fixed box 4. An L-shaped groove 18 for the control rod 14 to move is provided on one side of the fixed box 4. The handle 7 is pulled upward to move the control rod 14 to the top of the short side of the L-shaped groove 18. At this time, the rectangular block 13 moves upward until the block 16 at one end of the control rod 14 enters the groove 153. The handle 7 is turned to rotate the control rod 14, thereby driving the positioning frame 1 to rise and fall by rotating the second bevel gear 10.

[0032] Finally, a block 16 is fixedly installed on one end of the control rod 14 close to the fixed seat 15, and a slot 153 adapted to the block 16 is provided on the fixed seat 15. Rectangular slots 151 are provided on both sides of the slot 153. A clamping block 17 is slidably connected to one side of the rectangular slot 151 close to the block 16. The inner bottom end of the clamping block 17 is set as a rounded corner. A spring 152 is fixedly connected between the rectangular slot 151 and the clamping block 17. When the rectangular block 13 moves upward until the block 16 at one end of the control rod 14 enters the slot 153, the block 16 squeezes the clamping blocks 17 on both sides of the slot 153. Due to the self-stress of the spring 152, the clamping block 17 clamps and fixes the block 16, so that the block 16 and the fixed seat 15 are in a fixed connection state, which is convenient for turning the handle 7 to rotate the second bevel gear 10.

[0033] Working principle: During the working process of the utility model, the handle 7 is first pulled to move the rectangular block 13 rotatably connected to the control rod 14 at one end of the handle 7, driving the sliding frame 12 to slide in the fixed box 4. At this time, the rectangular plate 121 fixedly installed on one side of the sliding frame 12 also moves, so that the moving rod 11 fixedly installed on one side of the rectangular plate 121 moves, driving the clamping plate 6 to clamp the rod body at the bottom of both sides of the bed, so that the positioning frame 1 is fixedly installed on the bed. At this time, the handle 7 is pulled upward to move the control rod 14 to the top of the short side of the L-shaped groove 18. At this time, the rectangular block 13 moves upward until the block 16 at one end of the control rod 14 enters the slot 153, so that the block 16 clamps the two sides of the slot 153. The clamping block 17 is squeezed, and due to the self-stress of the spring 152, the clamping block 17 clamps and fixes the clamping block 16, and then the handle 7 is turned to rotate the control rod 14, driving the fixed seat 15 to rotate, thereby driving the second bevel gear 10 to rotate, so that the first bevel gear 9 meshing with the second bevel gear 10 is also rotated, so that the screw 8 fixedly connected to the first bevel gear 9 is also rotated, so that the moving member 5 is lifted and lowered in the fixed box 4, so that the positioning frame 1 fixedly installed on the moving member 5 is lifted and lowered, so that the two functions of fixing the positioning frame on both sides of the bed and adjusting the vertical height of the positioning frame can be realized by moving and rotating the handle, reducing the use process of placing the positioning frame, simple operation, and convenient use.

[0034] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
