Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary puncture positioning, in particular to an auxiliary puncture positioning device. Background Art

[0002] When medical staff treat patients, they will use medical equipment to assist in the treatment and help patients achieve rapid recovery. In clinical practice, medical staff will perform puncture treatment on the patient's bones, and auxiliary puncture positioning devices are needed during the puncture process to ensure the puncture effect;

[0003] However, the existing auxiliary puncture positioning device still has certain use defects during use. In the actual puncture operation, the doctor's control of the puncture angle and depth measured by CT is completed by experience and feeling. The doctor needs to rely on his own experience and hand feeling to complete the operation. If the doctor does not have enough experience, he must make multiple adjustments to confirm the insertion angle of the puncture needle, which prolongs the puncture time and increases the risk caused by the swinging process of the puncture needle. In addition, the damage to the tissue caused by multiple insertions is likely to cause heavy bleeding.

[0004] Patent application announcement number CN116849769A discloses an auxiliary puncture operation positioning device, which drives the slide seat up and down by a motor, and then drives the positioning cylinder to move to the puncture site, inserts the puncture needle into the puncture hole and turns the screw to drive the clamping block close to the fixed block to clamp and fix the puncture needle, drives the tooth plate to move by adjusting the electric cylinder, and then drives the positioning cylinder to rotate, the needle insertion angle can be adjusted, and the angle sensor can measure the needle insertion angle and display it on the display screen, moves the slide plate downward to drive the puncture needle to complete the puncture operation, the displacement sensor can measure the needle insertion depth, and the needle insertion angle is adjusted by driving the positioning cylinder to rotate, and the needle insertion depth is adjusted by moving the slide plate. With the accurate measurement of the angle sensor and the displacement sensor, the needle insertion angle and the needle insertion depth can be accurately controlled without multiple adjustments, which reduces the puncture time and the risk of puncture, and is conducive to completing the auxiliary positioning during the puncture operation.

[0005] The patent application announcement number CN215192070U discloses a positioning device for auxiliary puncture, which connects the puncture needle through a connecting ring, and clamps the second elastic clamping block in the corresponding second clamping groove. At this time, the fixing plate can be fixed on the top of the two second support plates, and the second positioning ring is pressed downward. After the second positioning ring is subjected to force, it will squeeze the first support plate. After the first support plate is subjected to force, it will compress the first spring, and the length of the first spring will be shortened. At the same time, after the first support plate is subjected to force, it will drive the second spring and the first elastic clamping block to move downward together. When the first elastic clamping block moves to the position of the first clamping groove, the first elastic clamping block will pop out from the inside of the fixing groove under the elastic force of the second spring and clamp in the inside of the first clamping groove, fixing the second positioning ring. Compared with the prior art, it can be quickly disassembled and assembled, saving disassembly and assembly time, facilitating the fixing of the puncture needle, and being more convenient to use.

[0006] In the above-mentioned patent disclosure, the device solves the above-mentioned problems, but the following problems still exist during the use of the device. During the use of the device, the device needs to be fixed and adjusted, and then puncture can be performed with a puncture needle. During the fixing process of the device, it can only be adjusted in a single angle direction. In actual use, in order to meet the puncture needs, medical staff need to perform puncture at multiple angles, while the above-mentioned device can only be adjusted in a single angle direction.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Embodiment 1: This embodiment Figure 1-Figure 7 and Fig.13As shown, in order to solve the problem of unstable fixation of the existing device, the fixing and installation process of the device is disclosed, and the high stability effect of the device is achieved. The specific contents are as follows:

[0044] The positioning structure includes a driving screw 32 rotatably mounted on the lower end of the fixed base 1 , and an extrusion plate 36 is threadedly mounted on the outer side of the driving screw 32 , and the extrusion plate 36 is located directly below the fixed base 1 .

[0045] The positioning rod 33 is fixedly installed inside the fixed base 1 and the extrusion plate 36, and the supporting spring 35 and the limiting plate 34 are slidably installed outside the positioning rod 33, and the ends of the two sets of limiting plates 34 that are away from each other are arranged in an inclined shape.

[0046] When using the auxiliary puncture positioning device, the device is first installed at the position where it needs to work. During the installation of the device, the fixed base 1 and the extrusion plate 36 need to be located at the upper and lower sides of the operating table, and then the driving screw 32 can be rotated. The driving screw 32 is provided with three groups, and the rotation of the driving screw 32 will make the extrusion plate 36 approach the fixed base 1, so that the extrusion plate 36 and the fixed base 1 limit the clamping of the operating table;

[0047] The limiting plate 34 is tilted near the fixed base 1 and the extrusion plate 36 to increase friction when the device slides, thereby ensuring the stability of the device installation.

[0048] Afterwards, the driving motor 21 can drive the output shaft 19 to rotate, and a pulley structure is provided on the outer side of the output shaft 19 and the driven shaft 20, so that the output shaft 19 and the driven shaft 20 can rotate synchronously, and the output shaft 19 and the driven shaft 20 are threadedly connected to the sliding block 4, so that the sliding block 4 can move up and down.

[0051] A rotating frame 7 is rotatably installed inside the flip plate 6, and a positioning frame 8 is slidably installed inside the rotating frame 7, and a puncture hole 9 is opened inside the positioning frame 8, a rotating member 16 is rotatably installed inside the sliding block 4, and the rotating member 16 is fixedly connected to the rotating member 10, and a mounting member 17 is fixedly installed at one end of the rotating member 16 away from the rotating member 10, and the mounting member 17 is rotatably connected to the sliding block 4, and an electric push rod 11 is arranged inside the telescopic member 5, and the two ends of the electric push rod 11 are respectively fixedly connected to the flip plate 6 and the rotating member 10;

[0052] The rotating structure includes a rotating gear 15 and a sliding rack 13. The rotating gear 15 is fixedly mounted on the outside of the rotating frame 7 and is located inside the flip plate 6. The sliding rack 13 is slidably mounted inside the flip plate 6 and is meshed with the rotating gear 15.

[0053] Two sets of rotating screws 14 are rotatably installed inside the flip plate 6, and the rotating screws 14 are threadedly connected to the sliding rack 13, and a turntable assembly 12 is rotatably installed at one end of the flip plate 6 away from the telescopic member 5, and a pulley structure is arranged on the outer side of the turntable assembly 12 and the rotating screws 14;

[0054] The rotating structure further includes a clamping member 22, and the clamping member 22 is slidably mounted inside the rotating member 16, and a return spring 23 is fixedly mounted on one end of the clamping member 22 close to the rotating member 16, and the return spring 23 is located inside the rotating member 16;

[0055] A snap-fit ​​groove 25 is provided inside the sliding block 4, and the snap-fit ​​groove 25 is snap-fitted with the snap-fit ​​member 22, and the snap-fit ​​grooves 25 are distributed at equal angles with respect to the central axis of the rotating member 16, and a pulling block 18 is slidingly installed inside the end of the mounting member 17 away from the rotating member 16, and a traction rope 24 is fixedly installed on the end of the pulling block 18 close to the mounting member 17, and the end of the traction rope 24 away from the pulling block 18 is fixedly connected to the snap-fit ​​member 22.

[0056] When using the auxiliary puncture positioning device, after the device is installed on the outside of the operating table, the angle of the puncture hole 9 inside the device can be adjusted according to needs, so as to facilitate the placement of the puncture needle through the puncture hole 9 and perform puncture;

[0057] In the process of adjusting the angle of the puncture hole 9, it is necessary to first pull the pulling block 18 to slide outward inside the mounting member 17. During the movement of the pulling block 18, the engaging member 22 will be pulled to move by the traction rope 24, and the engaging member 22 will be away from the engaging groove 25 during the movement, and the reset spring 23 will be squeezed during the movement of the engaging member 22, and the reset spring 23 will shrink after being squeezed, and after the engaging member 22 is separated from the engaging groove 25, the mounting member 17 can be driven to rotate by the pulling block 18, and the mounting member 17 can be rotated. When the mounting member 17 rotates, the rotating member 10 is driven to rotate through the rotating member 16. At this time, the telescopic member 5 and the flip plate 6 can be driven to rotate through the rotating member 10. At this time, the rotating frame 7 and the positioning frame 8 can be rotated at a front-back angle. After the vertical angle of the puncture hole 9 is adjusted, the pulling block 18 can be released. At this time, the contracted return spring 23 will expand and push the engaging member 22 to move, and the engaging member 22 will engage with the engaging groove 25 again during the movement, thereby completing the initial angle adjustment of the puncture hole 9;

[0058] After that, the medical staff can shake the turntable assembly 12 to rotate it, and the rotation of the turntable assembly 12 will drive the two sets of rotating screws 14 to rotate through the pulley structure. The rotation of the rotating screws 14 will cause the sliding rack 13 to slide inside the flip plate 6. At this time, the sliding rack 13 can drive the rotating gear 15 meshing with it to rotate, and the rotation of the rotating gear 15 will drive the rotating frame 7 and the positioning frame 8 to rotate again, thereby completing the final rotation angle adjustment of the puncture hole 9, and achieving the effect that the device can perform multi-angle puncture.

[0059] Embodiment 3: This embodiment is as follows Figure 1-Figure 11 As shown, in order to solve the problem that the device can avoid puncturing too deep or too shallow, the working process of the internal positioning structure of the device is disclosed, and the effect that the device can accurately control the puncture depth is achieved. The device has a fixed base 1 and a support frame 2 fixedly installed on the upper end of the fixed base 1;

[0060] The positioning structure includes a rotating cylinder 26, and the rotating cylinder 26 is rotatably mounted inside the positioning frame 8, and the central axis of the rotating cylinder 26 and the central axis of the puncture hole 9 are in the same straight line, and a limiting gear ring 27 is fixedly mounted on the lower end of the rotating cylinder 26;

[0061] The positioning structure further includes a support tube 30, and the support tube 30 is slidably mounted inside the positioning frame 8, and one end of the support tube 30 away from the positioning frame 8 is located inside a support groove 31 provided in the rotating frame 7, and the support groove 31 is provided equidistantly inside the rotating frame 7, the rotating frame 7 is made of a transparent material, and the outer side of the rotating frame 7 is marked with scale lines;

[0062] A driven screw 28 is internally threadedly installed at one end of the support tube 30 close to the positioning frame 8, and the driven screw 28 is rotationally connected to the positioning frame 8. A driven gear 29 is fixedly installed at one end of the driven screw 28 close to the positioning frame 8, and the driven gear 29 is fixedly connected to the limiting gear ring 27.

[0063] After the device completes the angle adjustment, it is necessary to control the height of the puncture hole 9 to facilitate accurate control of the puncture depth of the puncture needle;

[0064] In this process, the rotating cylinder 26 needs to be rotated. The rotation of the rotating cylinder 26 will drive the limit gear ring 27 fixed at its lower end to rotate synchronously, and the rotation of the limit gear ring 27 will drive the slave gear 29 meshing with it to rotate. At this time, the slave gear 29 can drive the driven screw 28 to rotate, and the rotation of the driven screw 28 will make the support cylinder 30 approach the direction of the slave gear 29 and move away from the support groove 31. After the support groove 31 is separated from the support cylinder 30, the positioning frame 8 can be placed inside the rotating frame 7. It moves up and down, and the position of the positioning frame 8 can be observed through the scale lines on the outside of the rotating frame 7. After the positioning frame 8 moves to the required position, the rotating cylinder 26 can be rotated in the reverse direction. At this time, the rotating cylinder 26 will drive the slave gear 29 to rotate in the reverse direction, and the supporting cylinder 30 will move away from the driven screw 28 and make the supporting cylinder 30 engage with the supporting groove 31 again, thereby limiting the position of the positioning frame 8 and the puncture hole 9, and then controlling the puncture depth of the puncture needle, ensuring the accuracy of the puncture of the device, and increasing the overall practicality.
