Description

Technical Field

[0001] The utility model relates to the technical field of calibration and positioning, in particular to an ultrasonic probe calibration and positioning device for living body puncture. Background Art

[0002] With the continuous advancement of medical technology, ultrasonic diagnosis plays an increasingly important role in medical operations such as biopsy. As the core component of ultrasonic diagnosis, the accuracy and stability of the ultrasonic probe are directly related to the precision and safety of the puncture. Therefore, it is particularly important to accurately calibrate and position the ultrasonic probe.

[0003] The patent application with the prior art announcement number CN 116458972 B discloses an ultrasonic probe calibration and positioning device for live puncture, including a water storage membrane shell, a puncture template and a movable bracket. The water storage membrane shell is a transparent water tank structure, and a pipe for inserting an ultrasonic probe is provided at the lower part of the water storage membrane shell, and a plurality of rows of mounting holes forming an array are provided at the top; a movable column capable of moving up and down is installed in the mounting hole, and a target point is provided at the bottom end of the movable column; the puncture template is provided on the outside of one of the side walls of the water storage membrane shell; the movable bracket is provided outside the water storage membrane shell, and the movable bracket includes a base provided with rollers and a feeding device provided on the base, and the ultrasonic probe is fixedly connected to the feeding device and moves in the pipe under the drive of the feeding device. By adjusting the installation position and installation height of the movable column in different mounting holes, the coordinates of the target point can be changed, so that the coordinates of the ultrasonic image measured by the ultrasonic probe for the target point and the coordinates of the template image are aligned.

[0004] The above-mentioned prior art facilitates adjusting the installation position and installation height of the movable column in different installation holes, and can change the coordinates of the target point, thereby realizing the change of the calibration plate. However, in actual applications, a single calibration plate needs to frequently switch the target point coordinates. At the same time, during calibration, a single calibration plate can only calibrate the ultrasonic probe from a single angle or position, and cannot obtain comprehensive data. Furthermore, a single calibration plate cannot obtain multiple sets of repeated data for verification and comparison, which limits the reliability of the calibration results to a certain extent. To this end, we propose an ultrasonic probe calibration and positioning device for in vivo puncture. Utility Model Content

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] See also Figure 1-9The utility model provides a technical solution: an ultrasonic probe calibration and positioning device for live puncture, comprising a bottom plate 100, a top plate 101 and an ultrasonic probe 102, the bottom of the top plate 101 is rotatably connected to a plurality of calibration plates 204, the top of the bottom plate 100 is fixedly connected to a rotating mechanism 401, and the output end of the rotating mechanism 401 is fixedly connected to a bracket 400 for placing the ultrasonic probe 102, and both sides of the bracket 400 are respectively provided with fixing plates 406 for fixing the ultrasonic probe 102, the top of the bottom plate 100 is fixedly connected to a plurality of sleeves 300, and the plurality of sleeves 300 A transmission assembly for driving the fixed plate 406 to move is arranged between the top plate 101 and the fixed plate 406, a driving assembly for driving multiple calibration plates 204 to flip synchronously is arranged at the bottom of the top plate 101, and a linkage assembly for driving the transmission assembly to start is arranged inside the top plate 101. By setting multiple calibration plates 204 and performing rapid calibration with an ultrasonic probe 102 respectively, the accuracy of calibration can be improved, and the transmission assembly can facilitate the fixing of the ultrasonic probe 102, and the linkage assembly can improve the overall automation of the device, wherein the rotating mechanism 401 can be a servo motor-type transmission mechanism to apply mechanical rotation to the bracket 400.

[0038] In the preferred technical solution of this embodiment, in order to facilitate the synchronous unfolding of multiple calibration plates 204 so as to facilitate the calibration of the ultrasonic probe 102, and to simultaneously retract the multiple calibration plates 204 so as to reduce the footprint of the device, a driving assembly is provided, including multiple slide grooves opened at the bottom of the top plate 101, wherein the multiple slide grooves are respectively slidably connected with rack plates 206, and the middle ends of the multiple calibration plates 204 are respectively fixedly connected with rotating gears 205 meshing with the rack plates 206, and the top plate 101 is internally rotatably connected with a rotating shaft 207, and the rotating shaft 207 The bottom is fixedly connected with a transmission gear 208 meshing with the rack plate 206, the tops of the multiple rotating shafts 207 extend to the top of the top plate 101 and are fixedly connected with a pinion 203, the top of the top plate 101 is rotatably connected with an inner ring tooth 202, and the inner ring tooth 202 is respectively meshed with the multiple pinions 203, the top of the top plate 101 is fixedly connected with a protective shell 200, the top of the protective shell 200 is fixedly connected with a driving motor 201, and the output end of the driving motor 201 extends to the inside of a pinion 203 and is fixedly connected to it.

[0039] Specifically, by turning on the driving motor 201, a small gear 203 is driven to rotate, thereby driving the inner ring gear 202 to rotate. At this time, the inner ring gear 202 will simultaneously drive multiple small gears 203 to rotate, and then multiple rotating shafts 207 rotate at the same time, thereby driving the transmission gear 208 to drive the rack plate 206 to move. At this time, when the rack plate 206 moves toward the side close to the calibration plate 204, it will engage with the rotating gear 205, thereby driving the calibration plate 204 and the top plate 101 to flip over. Finally, multiple calibration plates 204 will be unfolded at the same time. The inner ring gear 202 is provided to facilitate the synchronous transmission of multiple small gears 203, and with the cooperation of the rack plate 206, multiple calibration plates 204 can be synchronously unfolded or folded, thereby improving the overall flexibility and automation of the device.

[0040] In the preferred technical solution of this embodiment, in order to improve the overall automation of the device, the position of the top plate 101 can be raised or lowered at the same time, so that the ultrasonic probe 102 is on the same horizontal line when calibrated with the calibration plate 204, and a linkage assembly is provided, including a plurality of screws 301 rotatably connected to the inside of the top plate 101, the plurality of screws 301 are respectively adapted to be threadedly connected to the top of a plurality of sleeves 300, the bottoms of the plurality of screws 301 extend to the inside of the sleeve 300 and are fixedly connected to a first piston, the tops of the plurality of screws 301 are respectively fixedly connected to driven wheels 302, and the tops of the plurality of pinions 203 are fixedly connected to a driving wheel 303 belt-connected to the driven wheel 302.

[0041] Specifically, when the pinions 203 rotate simultaneously, several individual pinions 203 will drive the driving wheel 303 on the top to rotate, thereby driving the driven wheel 302 to rotate through the belt drive and then driving multiple screws 301 to rotate at the same time. At this time, the screw 301 is threadedly connected to the sleeve 300 and gradually separated, thereby increasing the height of the top plate 101, so that 120 is aligned with multiple calibration plates 204, and the driven wheel 302 and the driving wheel 303 are connected by a belt, so that the screw 301 and the pinion 203 rotate synchronously, thereby improving the overall automation operation of the device, and when the top plate 101 is raised, it provides space for the calibration plate 204 to unfold, and the mutual cooperation between the two can effectively improve the calibration efficiency between the ultrasound probe 102 and the multiple calibration plates 204.

[0042] In the preferred technical solution of the present embodiment, in order to fix the ultrasonic probe 102 and avoid dislocation of the ultrasonic probe 102 during rotation, while at the same time considering the convenience of subsequent removal of the ultrasonic probe 102, the transmission assembly includes an air cylinder 404 fixedly connected to the inside of the bracket 400, and movable rods 405 are slidably connected to both ends of the air cylinder 404, and the ends of the two movable rods 405 away from each other are fixedly connected to two fixed plates 406, respectively, and the two movable rods 405 extend to the inside of the air cylinder 404 and are fixedly connected to the second piston, and the two ends of the air cylinder 404 are respectively connected to telescopic air pipes 403, wherein the structural material of the telescopic air pipes 403 is carbon steel, and the ends of the two telescopic air pipes 403 away from each other are fixedly connected to the air supply pipe 402 connected to the sleeve 300.

[0043] In summary, when the screw 301 and the sleeve 300 move away from each other, the piston at the bottom will be driven to absorb the gas in the gas pipe 402. The absorbed gas is provided by the gas cylinder 404, so that the gas in the gas cylinder 404 is reduced, which in turn drives the two movable rods 405 to move closer to each other and then drives the two fixed plates 406 to clamp and fix the ultrasonic probe 102. When the screw 301 moves closer to the sleeve 300, it will push the two fixed plates 406 away from each other, thereby releasing the fixation of the ultrasonic probe 102.

[0044] Working principle:

[0045] By placing the ultrasonic probe 102 on the top of the bracket 400, the driving motor 201 is turned on to drive a small gear 203 to rotate, thereby driving the inner ring gear 202 to rotate. At this time, the inner ring gear 202 will simultaneously drive multiple small gears 203 to rotate, and then multiple shafts 207 will rotate at the same time to drive the transmission gear 208 to drive the rack plate 206 to move. At this time, when the rack plate 206 moves to the side close to the calibration plate 204, it will mesh with the rotating gear 205 to drive the calibration plate 204 and the top plate 101 to flip, and finally multiple calibration plates 204 will be unfolded at the same time;

[0046] When the plurality of pinions 203 rotate simultaneously, some of the pinions 203 will drive the driving wheel 303 on the top thereof to rotate, thereby driving the driven wheel 302 to rotate through the belt drive and then driving the plurality of screws 301 to rotate simultaneously. At this time, the screws 301 are threadedly connected with the sleeve 300 and gradually separated, thereby increasing the height of the top plate 101, so that the ultrasonic probe 102 is aligned with the plurality of calibration plates 204;

[0047] At the same time, when the screw rod 301 and the sleeve 300 move away from each other, the piston at the bottom will be driven to absorb the gas in the gas pipe 402. The absorbed gas is provided by the gas cylinder 404, so that the gas in the gas cylinder 404 is reduced, and then the two movable rods 405 are driven to move closer to each other, and then the two fixing plates 406 are driven to clamp and fix the ultrasonic probe 102.

[0048] Subsequently, the rotating mechanism 401 can be turned on to drive the bracket 400 to rotate and then drive the ultrasonic probe 102 to rotate to calibrate multiple calibration plates 204 in turn. At this time, the telescopic air tube 403 is bent under force to facilitate the rotation of the bracket 400. Each calibration plate 204 has known size and position information, which can be compared and corrected with the measurement results of the ultrasonic probe 102, and the ultrasonic probe performance data from different directions can be obtained.
