Description

Technical Field

[0002] In modern clinical medical surgery, accurate positioning of small lesions is one of the key links to ensure the success of the operation. Ultrasound diagnostic technology is widely used for preoperative positioning of small lesions due to its many advantages such as being non-invasive, real-time, and convenient. However, traditional ultrasound positioning operation methods have significant defects: on the one hand, medical staff usually hold the ultrasound probe directly, which can easily lead to hand fatigue after long-term operation, making it difficult to maintain the probe stable, resulting in jitter and blurring of the ultrasound image, seriously affecting the accurate judgment of the location of small lesions. On the other hand, different surgical sites have different requirements for the angle, height, and distance between the ultrasound probe and the lesion. Relying on medical staff to manually hold and adjust the ultrasound probe is not only cumbersome and inefficient, but also difficult to accurately detect the required location for a long time. To overcome these problems, there is an urgent need for a handheld device that can facilitate medical staff to operate, adjust, and stably clamp the ultrasound locator to improve the efficiency and accuracy of preoperative ultrasound positioning of small lesions.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] The embodiment of the present invention discloses a handheld preoperative ultrasound positioning device for clinical small lesions.

[0030] Reference Figure 1-6 A handheld preoperative ultrasound positioning device for clinical small lesions includes an adjustment seat assembly 1, a placement pole 2 is slidably provided on the surface of the adjustment seat assembly 1, a placement sleeve 3 is provided on the outer side of the support pole, and the outer side of the anti-placement sleeve is fixedly connected to the surface of a grip frame 4, and a locking assembly 13 is provided at the bottom end of the grip frame 4. The locking assembly 13 is used to fix the grip frame 4 at a suitable position outside the placement pole 2; the grip frame 4 is designed according to ergonomics to fit the hand's grip curve, reducing hand fatigue caused by long-term operation;

[0031] An adjustment boss 5 is provided at a top corner of the handle frame 4, and a connecting column 6 is rotatably installed in the adjustment boss 5 through a damping shaft, and an adjusting rod 7 is slidably provided in the connecting column 6. The top end of the adjusting rod 7 is fixedly connected to the universal shell 9 through a support frame 8, and a universal ball 10 is rotatably installed in the universal shell 9, and the other end of the universal ball 10 is fixedly connected to the clamping assembly 11, and an ultrasonic locator 12 is detachably clamped and fixed in the clamping assembly 11; the damping shaft gives the connecting column 6 the ability to rotate at multiple angles, and combined with the universal ball 10 in the universal shell 9, the ultrasonic locator 12 can be freely rotated in the horizontal and pitch directions. No matter whether it is a deep organ or a small lesion in a superficial part, it can be easily aligned, which greatly improves the positioning accuracy and operational flexibility.

[0032] The clamping assembly 11 includes a clamping housing 14 and a transmission plate 22. The clamping housing 14 has a built-in groove 15, and a reinforcement slide bar is fixedly installed on the inner wall of the built-in groove 15. The two ends of the reinforcement slide bar are respectively slidably provided with a clamping adjustment block 17. One side of the reinforcement adjustment block 102 is fixedly connected to the clamping mechanism via a guide rod 18, and the guide rod 18 slides through the reinforcement housing.

[0033] The bottom ends of the two sets of reinforcement adjustment blocks 102 are provided with guide grooves 21. The two ends of the transmission plate 22 are respectively spliced and slid in the guide grooves 21 at the bottom ends of the two sets of reinforcement adjustment blocks 102. The bottom ends of the guide grooves 21 are fixedly connected to the clamping mechanism through the moving rod 23. The moving rod 23 slides through the clamping housing 14.

[0034] A spring frame A24 is sleeved on the outer side of the moving rod 23 , one end of the spring frame A24 is fixedly connected to the built-in groove 15 , and the other end of the spring frame A24 is fixedly connected to the bottom surface of the transmission plate 22 .

[0035] The three groups of clamping mechanisms include a guide block 19, which is fixedly connected to the guide rod 18. A clamping block 20 is fixedly installed on the other side of the guide block 19. The clamping block 20 is a "concave" structure and can limit and fix the side of the ultrasonic locator 12; the clamping slide bar 16 cooperates with the clamping adjustment block 17, and moves through the moving rod 23 to squeeze the spring frame A24 while driving the transmission plate 22, driving the guide rod 18 and the clamping block 20 to stably clamp the ultrasonic locator 12; among them, the "concave" structure of the clamping block 20 not only adapts to the shape of the ultrasonic locator 12, but also effectively prevents it from shaking and displacing during operation, thereby ensuring the stability of the ultrasonic detection after clamping.

[0036] A power module is provided in the grip frame 4, and a power switch 27 is provided on the surface of the grip frame 4. A bracket 25 is fixedly installed on the inner wall of the built-in groove 15, and a magnetic guide plate 26 is fixedly installed on the surface of the bracket 25. The magnetic guide plate 26, the power module, and the power switch 27 are electrically connected, and the transmission plate 22 has a built-in magnetic block. It is worth noting that in order to further achieve stable fixation of the ultrasonic locator 12, after the clamping assembly 11 initially completes the fixation of the ultrasonic locator 12, in order to further enhance the fixation effect, the medical staff only needs to operate the power switch 27 on the surface of the grip frame 4 to start the power module. The power module starts to power the magnetic guide plate 26, so that the magnetic guide plate 26 generates magnetic force, and generates a downward magnetic attraction force on the magnetic block built into the transmission plate 22, thereby further tightening the transmission plate 22, so that the clamping block 20 clamps the ultrasonic locator 12 more tightly, thereby improving the stability of the ultrasonic locator 12 during operation.

[0037] The universal circular shell 9 is electrically connected to the power module (there is a corresponding magnetic part in the universal circular shell 9) and the power switch 27. The surface of the universal ball 10 is set to silicone material, and a magnetic block is provided in the universal ball 10. Similarly, after power is turned on, the magnetic block can interact with the corresponding magnetic part in the memory of the universal circular shell 9. When the ultrasonic locator 12 is adjusted to a suitable angle, the magnetic block can assist in fixing the position of the universal ball 10, so that it can overcome external force interference to a certain extent and maintain the current posture.

[0038] The locking assembly 13 includes a groove 42, a groove 42 is provided on the top of the grip frame 4, and a slide groove 41 is provided on the surface of the groove 42, a round rod 43 is fixedly installed on the inner wall of the groove 42, and a column sleeve 45 is provided on the outer side of the other end of the round rod 43 for sliding. One end of the column sleeve 45 slides through the grip frame 4 and the placement sleeve 3, and is used to resist the placement pole 2 in the placement sleeve 3. A moving ring 46 is fixedly installed on the surface of the column sleeve 45, and the moving ring 46 slides in the slide groove 41. A spring frame B44 is provided on the outer side of the round rod 43, and one end of the spring frame B44 is fixedly connected to the groove 42, and the other end is fixedly connected to the column sleeve 45. The column sleeve 45 is made of silicone. The locking assembly 13 cleverly uses the spring frame B and the column sleeve 45 made of silicone. Medical staff only need to operate with one hand to overcome the slight elastic force to easily adjust the height of the grip frame 4 on the placement pole 2, and quickly fix it after releasing their hands.

[0039] It is worth noting that the design of the locking assembly 13 can not only facilitate medical personnel to statically fix and adjust the ultrasonic locator 12, but also facilitate medical personnel to quickly fix and place the ultrasonic locator 12 after dynamic use.

[0040] The adjustment seat assembly 1 includes an adjustment outer frame 101, a guide groove 21 is opened at the upper end of the adjustment outer frame 101, an adjustment block 102 is fixedly installed on the inner wall of the adjustment outer frame 101, a splicing slider 103 is slidably mounted on the outer side of the adjustment block 102, and a placement pole 2 is fixedly installed on the upper surface of the splicing slider 103. The placement pole 2 slides in the guide groove 21. This structure can facilitate horizontal adjustment.

[0041] A threaded hole is provided on the surface of the connecting column 6 , and a threaded screw 61 is threadedly connected in the threaded hole. The threaded screw 61 is rotated to fix the position of the adjusting rod 7 .

[0042] In the present invention, the adjustment seat assembly 1 is placed steadily on a suitable plane close to the patient's surgical site to ensure that it will not shake or move, providing a stable foundation for subsequent operations; then the vertical rod 2 is pushed and placed by hand to make it slide smoothly in the guide groove 21 at the upper end of the adjustment outer frame 101. Based on the preliminary judgment of the position of the small lesion before the operation, the components connected to it are driven to allow the ultrasonic locator 12 to quickly approach the target area, complete the preliminary horizontal positioning, and make the ultrasonic locator 12 roughly align with the position of the lesion; then, hold the handle frame 4 with one hand, and touch the moving ring 46 at the top groove 42 with your fingers. , push the movable ring 46 with a little force to overcome the elastic force of the spring frame B44 outside the round rod 43. At this time, the silicone column sleeve 45 will move synchronously with the movable ring 46, and one end of it will slide in the grip frame 4 and the placement sleeve 3 to change the pressing position with the placement pole 2, so as to adjust the grip frame 4 to the appropriate height according to the height requirement of the surgical site. Release your fingers, and the spring frame B44 will rebound quickly, pushing the column sleeve 45 tightly against the placement pole 2, thereby fixing the grip frame 4 at the desired position outside the placement pole 2, and realizing the preliminary adjustment of the vertical height of the ultrasonic locator 12;

[0043] Then, the ultrasonic locator 12 is installed, and the ultrasonic locator 12 is placed on the surface of the clamping shell 14 of the clamping assembly 11. The moving rod 23 is pushed inward, and the moving rod 23 drives the transmission plate 22 to slide in the guide groove 21 at the bottom end of the two sets of clamping adjustment blocks 17, squeezing the spring frame A24, and the spring frame A24 is stretched; as the transmission plate 22 moves, the guide rod 18 is driven to move outward through the clamping adjustment block 17, and slides toward each other on the reinforced sliding rod of the clamping adjustment block 17, thereby causing the clamping fixing block 20 to open from both sides. At this time, the ultrasonic locator 12 can be placed, and its clamping positioning block fixes the ultrasonic locator 12; then, the force acting on the moving rod 23 is released, so that the elastic force generated by the spring frame A24 tightly clamps the ultrasonic locator 12, preliminarily fixing the position of the ultrasonic locator 12 to prevent it from shaking;

[0044] Subsequently, the power switch 27 on the surface of the grip frame 4 is pressed as needed to turn on the power module, which supplies power to the magnetic guide plate 26. The magnetic guide plate 26 generates magnetic force to attract the magnetic block built into the transmission plate 22, further tightening the transmission plate 22, allowing the clamping block 20 to clamp the ultrasonic locator 12 more firmly and tightly, ensuring that the ultrasonic locator 1212 will not be displaced during subsequent operations, thereby ensuring the stability of ultrasonic detection;

[0045] Then, hold the handle frame 44 where the connecting column 6 is located with your hand, and gently rotate the connecting column 6. Relying on the characteristics of the damping shaft, the connecting column 6 can be flexibly rotated at multiple angles, driving the adjusting rod 7, the supporting frame 8, the universal shell 9 and the ultrasonic locator 12 to rotate synchronously, so as to achieve precise angle adjustment of the ultrasonic locator 12 in the horizontal direction, so that it can avoid the possible blocking structures in the surgical area and accurately aim at the lesion; at the same time, the other hand can gently move the universal ball 10, which is spliced and rotated in the universal shell 9, driving the ultrasonic locator 12 to achieve free and precise rotation in the pitch direction, further optimizing the ultrasonic positioning. The detection angle of the locator 12 can be adjusted; during the adjustment process, the threaded nail 61 in the threaded hole on the surface of the connecting column 6 can be rotated according to actual needs to make it go deeper or withdrawn to fix the telescopic position of the adjusting rod 7, accurately control the distance between the ultrasonic locator 12 and the lesion, and ensure that the ultrasonic beam is accurately focused on the core area of the lesion; when the angle of the ultrasonic locator 12 is adjusted to the optimal state, press the corresponding power switch 27 again to make the magnetic part in the universal shell 9 interact with the magnetic block in the universal ball 10 to assist in fixing the position of the universal ball 10, overcome possible slight interference from the outside world, and allow the ultrasonic locator 12 to maintain a stable detection posture.

[0046] Switch to handheld use (if necessary):

[0047] When the surgical scene or operation requirements change and the fixed support function of the device is no longer needed, the medical staff can hold the handle frame 4 with one hand and pull it vertically upward from the placement sleeve 3 on the outside of the placement pole 2 to separate the handle frame 4 from the device body; after separation, the medical staff can conveniently hold the handle frame 4 and flexibly operate the ultrasonic locator 12 like a traditional handheld ultrasonic probe, meeting the diverse needs of different surgical links for ultrasonic positioning.
