[0002] Renal puncture is a renal biopsy, also known as renal puncture biopsy. It is a pathological biopsy of an appropriate amount of renal tissue obtained by puncture to determine the pathological type of kidney disease. It is of great significance in assisting the diagnosis of renal parenchymal diseases, guiding treatment and judging the prognosis. Renal biopsy is a traumatic examination and may result in injury, bleeding or infection.

Due to the existence of the limiting bar and the elastic column, the polygonal cylinder cannot drive the one-way rotating gear to rotate.

[0008] Furthermore, the automatic timing control component includes a support seat, a rotating column, a bevel gear wheel, a uniform speed wheel and a uniform speed transmission source component.

[0011] Furthermore, the opposing tensioning assembly includes a limiting column, a double-tooth clamping rod, a single-tooth clamping rod, limiting teeth, clamping limbs, a clamping arc, a pull-back spring, a transmission column and a linkage wheel. The limiting column is provided with two groups, and the bottom ends of the two groups of limiting columns are fixed on the bracket. The double-tooth clamping rod is slidably provided on one group of limiting columns, and the single-tooth clamping rod is slidably provided on the other group of limiting columns. The end of the clamping power tooth plate is fixedly provided on the single-tooth clamping rod, one end of the limiting tooth is fixedly provided on the double-tooth clamping rod, and the other end of the limiting tooth is slidably provided on the bracket. There are two groups of clamping limbs, one end of which is fixedly provided on the double-tooth clamping rod, and the other end of which is slidably provided on the bracket. The clamping limbs are provided with two groups, one end of which is fixedly provided on the double-tooth clamping rod, and the other end of which is slidably provided on the bracket. The other end of the clamping limbs is fixedly provided on the single-tooth clamping rod, and the other end of the other group of clamping limbs is slidably provided on the bracket.

[0012] Furthermore, the compression assembly includes a fixed frame, a polygonal threaded rod, a positioning rotating wheel, a lifting plate, a lifting threaded rod, a rotating wheel, an upper and lower plates and a hemostatic pack. The bottom end of the fixed frame is fixedly arranged on the bracket, the polygonal threaded rod is threadedly arranged on the bracket, the polygonal threaded rod is slidably arranged on the fixed frame, the upper part of the polygonal threaded rod is a polygon, the positioning rotating wheel is slidably arranged on the polygonal threaded rod, the positioning rotating wheel is meshed with the double-tooth clamping rod, the lifting plate is rotatably arranged on the bottom end of the polygonal threaded rod, the lifting threaded rod is threadedly arranged on the lifting plate, the rotating wheel is fixedly arranged on the top of the lifting threaded rod, the upper and lower plates are rotatably arranged on the bottom end of the lifting threaded rod, and the hemostatic pack is arranged on the upper and lower plates. The polygonal threaded rod is rotated by the positioning rotating wheel, so that the lifting plate moves up and down, and then the hemostatic pack compresses the puncture site of the patient to stop bleeding, and the rotation of the lifting threaded rod can also make the hemostatic pack move up and down to adapt to patients with different body shapes.

[0013] The beneficial effects achieved by the present invention using the above structure are as follows:

[0014] (1) The double-tooth clamping rod is designed to have teeth on both sides. When the double-tooth clamping rod moves, the single-tooth clamping rod is transmitted through the linkage wheel, so that the double-tooth clamping rod and the single-tooth clamping rod move relatively. The double-tooth clamping rod and the single-tooth clamping rod move synchronously, achieving the effect of synchronous clamping or synchronous relaxation of the patient by the compression hemostasis device. At the same time, the double-tooth clamping rod can also drive the positioning rotating wheel to rotate, providing a power source for the timing of the device;

[0015] (2) When the limiting teeth are stuck and the two sets of clamping arcs clamp the patient, the polygonal threaded rod no longer drives the lifting plate to descend. Instead, the height of the hemostatic pack can be adjusted by adjusting the lifting threaded rod, thereby achieving the technical effect of compressing and stopping bleeding for patients with different body shapes;

[0016] (3) When the double-tooth clamping rod and the single-tooth clamping rod move relative to each other, the electrostrictive grafted elastomer 1 is in a state of being energized and extended, and the clamping power tooth plate can drive the polygonal cylinder to rotate through the sliding gear to tighten the mainspring, thereby achieving the effect of synchronous timing and power storage. At the same time, the polygonal cylinder drives the rebound power storage tooth plate to move through the uniform speed transmission wheel. When the double-tooth clamping rod and the single-tooth clamping rod move in the opposite direction, the electrostrictive grafted elastomer 1 is in a state of being de-energized and contracted, and the sliding gear loses the meshing connection state with the clamping power tooth plate. The reverse rotation of the polygonal cylinder will not have any effect on the clamping power tooth plate, thereby achieving the technical effect of synchronously tightening the mainspring while the clamping power tooth plate moves inward and asynchronously restoring the original state;

[0017] (4) The one-way rotating gear is arranged on the polygonal cylinder, and a one-way tooth is arranged on the inner wall of the one-way rotating gear, which cooperates with the limiting strip and the elastic column, so that when the polygonal cylinder rotates clockwise, the one-way rotating gear does not rotate with the rotation of the polygonal cylinder, and when the polygonal cylinder rotates counterclockwise, the limiting strip is stuck on the inner teeth of the one-way rotating gear, and the one-way rotating gear rotates with the rotation of the polygonal cylinder. On the one hand, it avoids the automatic timing control component from affecting the winding speed during the winding process of the mainspring, and on the other hand, the automatic timing control component makes the recovery time of the rebound storage tooth plate consistent;

[0018] (5) The mainspring releases energy, causing the uniform-speed wheel and the bevel gear wheel to rotate. The bevel gear wheel drives the swing fork to swing, and the other end of the swing fork drives the rotating pin to swing, thereby causing the hairspring to contract and relax. The frequency of the hairspring's swing per unit time is the same. The hairspring reacts on the swing fork, making the rotation speed of the bevel gear wheel constant, and the time it takes for the rebound storage tooth plate to return to the initial position is constant, thereby achieving the technical problem of precise time control;

[0019] (6) The control switch is electrically connected to the electrostrictive grafted elastomer 2. After the compression hemostasis at the puncture site is completed, the rebound force storage tooth plate squeezes the control switch, and the electrostrictive grafted elastomer 2 is de-energized and contracts, so that the limit pin loses its limiting effect on the limit tooth. Under the action of the return spring, the double-tooth clamping rod and the single-tooth clamping rod move in opposite directions, thereby achieving the technical effect of automatic expansion of the compression hemostasis device.

The rotating pin 29 swings back and forth once, causing the bevel gear wheel 23 to rotate one tooth. Due to the isochronism of the hairspring 30, that is, the frequency of the hairspring 30 causing the rotating pin 29 to swing back and forth in unit time is constant, so that the number of teeth of the bevel gear wheel 23 rotating in unit time is constant, the bevel gear wheel 23 drives the rotating column 22 to rotate at a constant speed, the rotating column 22 drives the uniform wheel 24 to rotate at a constant speed, and the uniform wheel 24 makes the reverse rotation speed of the one-way rotating gear 16 constant. The one-way rotating gear 16 makes the reverse rotation speed of the polygonal cylinder 12 constant, and the polygonal cylinder 12 drives the uniform speed transmission wheel 17 to rotate in the reverse direction, and the uniform speed transmission wheel 17 drives the rebound force storage tooth plate 9 to move in the reverse direction. When the rebound force storage tooth plate 9 returns to its original position, the rebound force storage tooth plate 9 squeezes the control switch 10, and the electrostrictive grafted elastic body 2 32 is de-energized and shrinks, and the electrostrictive grafted elastic body 2 32 drives the limit pin 33 to move in the reverse direction, so that the limit pin 33 loses the limiting effect on the limit tooth 37, and the pull-back spring 40 releases the elastic potential energy, so that the double-tooth clamping rod 35 and the single-tooth clamping rod 36 move in the reverse direction, so that the hemostatic pack 50 and the clamping arc 39 return to their original positions, and the compression hemostasis is completed.
