Detailed Description

The following describes the present invention in further detail with reference to fig. 1-5.

The utility model discloses a low limbs support 1, it is connected with two sets of curved clamp splices 2 of relative pivoted to rotate on the low limbs support 1, it is connected with cushion 3 to rotate on the clamp splice 2, 1 one side sliding connection of low limbs support has adjustable first slider 4, fixedly connected with bracing piece 5 on the first slider 4, it is connected with fixable's first connecting rod 6 to rotate on the bracing piece 5, sliding connection has adjustable second slider 7 on the first connecting rod 6, second slider 7 rotates and connects second connecting

rod

8, 8 opposite sides of second connecting rod rotate be connected with 5 sliding connection's of bracing piece third slider 9, it is connected with connecting rod 10 to rotate on the third slider 9, connecting rod 10 fixedly connected with guide block 11, it has guide way 12 that is used for the pjncture needle to remove to open on the guide block 11.

The lower limb support 1 is of a structure with a wide lower part and a narrow upper part, the contact area between the lower limb support 1 and the ground can be increased due to the wide bottom surface, the device is more stable when the lower limb support is placed, the arc-shaped groove is formed in the upper top surface of the lower limb support 1, the lower limb support can be more attached to the lower limb of a patient when the lower limb is placed, the fixing area during fixing is increased, the fixing stability is guaranteed, and puncture deviation caused by movement of the lower limb in the puncture process is avoided; the inner side of the cushion block 3 is provided with a flexible cushion layer, the two clamping blocks 2 can synchronously and reversely rotate relative to the lower limb support 1, the lower limbs of a patient can be fixed at the position of the central line of the lower limb support 1 under the action of the two clamping blocks 2, after the lower limbs of the patient are fixed, the position of the supporting rod 5 can be adjusted through the first sliding block 4 to move the guide block 11 back and forth to the position right above the part to be punctured, then the position of the first sliding block 4 is fixed, the vertical height of the third sliding block 9 and the guide block 11 is adjusted through the first connecting rod 6, the guide block 11 and the third sliding block 9 are rotatably connected through the connecting rod 10, the inclination angle of the guide block 11 can be adjusted through the connecting rod 10, and therefore the guide groove 12 of the guide block 11 can be selected to have more inclination angles, after the guide block 11 is fixed, the puncture needle is placed in the guide groove 12, then under the limiting effect of the guide groove 12, and medical staff can push the puncture needle to puncture the patient along the direction of the guide groove 12.

It is connected with first worm 13 to rotate on the lower limbs support 1, first worm 13 meshes has first worm wheel 14, the equal coaxial fixedly connected with carousel 15 in both sides around

first worm wheel

14, 15 eccentric fixedly connected with connecting pin 16 in one side of carousel, 16 sliding connection of connecting pin have with the 1 vertical sliding connection's of lower limbs support key type piece 17, key type piece 17 rotates and is connected with two third connecting rods 18 that are the V type and distribute, two 18 other both ends of third connecting rod rotate respectively with two clamp splice 2 to be connected, two 2 middle parts of clamp splice rotate with lower limbs support 1 jointly and are connected.

The two third connecting rods 18 and the two clamping blocks 2 form a rhomboid quadrilateral mechanism, when the first worm 13 rotates, the first worm 13 drives the meshed first worm wheel 14 to rotate, the first worm wheel 14 rotates to drive the rotary tables 15 on the front side and the rear side to synchronously rotate, the rotary tables 15 rotate to drive the connecting pins 16 to revolve, only the freedom degree of vertical sliding exists between the key-shaped block 17 and the lower limb support 1, a sliding groove with the same diameter as that of the rotary tables 15 is formed in the connecting block, when the connecting pins 16 revolve, the connecting pins 16 drive the key-shaped block 17 to vertically move, when the key-shaped block 17 wants to move, the key-shaped block 17 drives the hinged joint on the lower side of the two third connecting rods 18 to move upwards, the lower ends of the two clamping blocks 2 rotate outwards under the action of the third connecting rods 18, so that the upper ends of the two clamping blocks 2 drive the cushion blocks 3 to approach to the center of the lower limb support 1 to clamp a patient; conversely, when the key-shaped block 17 descends, the two clamping blocks 2 release the fixation of the lower limbs of the patient, and the reverse self-locking between the first worm wheel 14 and the first worm 13 can avoid the return movement of the clamping blocks 2 and the cushion block 3.

Two guide rods 19 are fixedly connected to one side of the lower limb support 1, the first sliding block 4 penetrates through the guide rods 19 and is in sliding connection with the guide rods 19, and a first fastening screw 20 is in threaded connection with the first sliding block 4.

Two guide bars 19 guarantee to have gliding degree of freedom between first slider 4 and the low limbs support 1, first fastening spiral shell pass first smooth one side and the contact of guide bar 19 in the first slider 4, when first slider 4 need be removed, loosen first fastening screw 20 to the state that compresses tightly of guide bar 19, later can remove the position of first slider 4 on guide bar 19, after the position removal, rotate first fastening screw 20 and can fix once more, make things convenient for medical personnel to control.

The first connecting rod 6 is fixedly connected with a bolt 21, the bolt 21 is rotatably connected with the supporting rod 5, and a fastening nut 22 for fixing is connected to the bolt 21 on the outer side of the supporting rod 5 in a threaded mode.

First connecting rod 6 one end is connected with bolt 21, when first connecting rod 6 needs to be rotated, it loosens with fastening nut 22 on the bolt 21 to need the user, reduce the frictional force between first connecting rod 6 and the bracing piece 5, later can drive the vertical lift of third slider 9 through rotating first connecting rod 6, as shown in the figure, when first connecting rod 6 rotates downwards, first connecting rod 6 drives second connecting rod 8 through second slider 7 and moves downwards, second connecting rod 8 length is the definite value, second connecting rod 8 moves downwards and drives third slider 9 and move downwards, third slider 9 drives guide block 11 through connecting rod 10 and carries out vertical removal, thereby change the vertical height of guide block 11, later fix the relative contained angle of first connecting rod 6 and bracing piece 5 through fastening nut 22 and bolt 21's effect, accomplish the fixed after the guide block 11 position shift.

The second sliding block 7 is sleeved on the first connecting rod 6, and a second fastening screw 23 for fixing is connected to the side face of the second sliding block 7 in a threaded mode.

The second slider 7 can advance the horizontal slip on first connecting rod 6, and when the first connecting rod is fixed, through sliding second slider 7, second slider 7 can drive third slider 9 through second connecting rod 8 and carry out the vertical movement of minizone, and second fastening screw 23 is the same with the fixed mode of first fastening screw 20.

The connecting rod 10 is an air cylinder telescopic rod, a second worm wheel 24 is coaxially and fixedly connected to one side of the connecting rod 10, and a second worm 25 rotatably connected with the third sliding block 9 is meshed with the second worm wheel 24.

Connecting rod 10 is common cylinder telescopic link in the life, through the position about the adjustable guide block 11 of connecting rod 10 to the cylinder telescopic link can carry out the auto-lock, and only the sub-degree of freedom of horizontal slip between the interior outer pole of cylinder telescopic link, second worm wheel 24 and second worm 25 can drive connecting rod 10 and rotate, and connecting rod 10 rotates and drives guide block 11 and carry out the regulation of angle.

The utility model discloses novel structure thinks about ingeniously, and easy operation is convenient, through the effectual medical personnel of having solved of this design fix a position the inaccuracy and take place the shake easily at puncture in-process hand to lead to the puncture can not once only succeed, bring too much painful problem for patient.
