[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0031] See also Figures 1 to 9 , the present invention provides a technical solution: A percutaneous lung puncture biopsy positioning auxiliary device comprises a convex slide rod 1, wherein the upper end of the convex slide rod 1 is in an open state, such as Figure 2 As shown, arc-shaped arc rods 101 are fixedly installed on the left and right sides of the front end of the convex slide rod 1 near the edge.

[0032] During use, the device is fixedly installed on the side of the operating table. Therefore, the arc rod 101 can be suitable for operating tables of different thicknesses, saving installation time.

[0033] Then, a first screw rod 102 is rotatably mounted on the lower end surface of the arc rod 101, a knob 103 is fixedly mounted on the lower end of the first screw rod 102 on the outside of the arc rod 101, and a gasket 104 is fixedly mounted on the upper end of the first screw rod 102 on the inside of the arc rod 101. Figure 2 shown.

[0034] During use, the lower end surface of the convex slide rod 1 and the upper end surface of the operating table are in a fitted state, and then the doctor turns the knob 103. An arc groove is provided on the circumferential surface of the knob 103 to facilitate the doctor's rotation. At this time, when the knob 103 is rotated, it can rotate synchronously with the first screw rod 102, and when the first screw rod 102 is rotated, it can rotate synchronously with the gasket 104. However, when the first screw rod 102 rotates, the gasket 104 will gradually approach the lower surface of the operating table until it is in a fitted state. At this time, the convex slide rod 1 is in a fixed state. When the first screw rod 102 is rotated in the opposite direction, the gasket 104 and the lower end of the operating table can be separated, so that the convex slide rod 1 can be removed. Figure 1 shown.

[0035] Secondly, servo motors 106 are fixedly installed at both ends of the convex chute rod 1, and a screw 105 is rotatably installed inside the convex chute rod 1. The left and right ends of the screw 105 pass through the convex chute rod 1 and are fixedly connected to the output shaft of the adjacent servo motor 106, such as Figure 2 As shown, a slide 107 is rotatably mounted on the circumferential surface of the screw 105, wherein the upper end of the slide 107 extends to the outside of the convex slide rod 1, as shown in FIG. Figure 2 shown.

[0036] During use, when the servo motor 106 at the left end rotates, it can drive the screw 105 to rotate synchronously, and when the screw 105 rotates, the slide 107 can move to the right along the path of the convex slide rod 1, and when the servo motor 106 at the right end drives the screw 105 to rotate, it can drive the slide 107 to the left along the path of the convex slide rod 1.

[0037] Then, a cavity rod 2 is fixedly installed on the upper end of the slide 107, wherein the top of the cavity rod 2 is in an open state and the interior is a cavity structure. Secondly, a dual-axis motor 201 is fixedly installed on both sides of the upper end of the cavity rod 2, and a first adjustment plate 202 is fixedly installed on the output shaft of the dual-axis motor 201. A second adjustment plate 203 is rotatably installed on the end of the first adjustment plate 202 away from the cavity rod 2, as shown in FIG. Figure 3 shown.

[0038] During use, when the dual-axis motor 201 rotates, it can drive the first adjustment plate 202 to rotate synchronously, and when the first adjustment plate 202 rotates, it can drive the second adjustment plate 203 to rotate synchronously.

[0039] Secondly, a support rod 204 is rotatably mounted on the inner side of the upper ends of the two second adjustment plates 203, wherein the lower end of the support rod 204 extends to the inside of the cavity rod 2, such as Figure 3As shown, during use, the second adjustment plate 203 can drive the support rod 204 to move upward or downward when it rotates. Moreover, during use, since the lower end of the support rod 204 is slidably installed inside the cavity rod 2, it is ensured that the support rod 204 will not shake, thereby ensuring the stability of the subsequent device.

[0040] Then, a stepper motor 3 is fixedly installed at the rear of the upper end of the support rod 204, a second screw rod 301 is fixedly installed on the output shaft of the stepper motor 3, a mounting support plate 302 is rotatably installed on the circumferential surface of the second screw rod 301, and then a slide bar 303 is fixedly installed on the left and right sides of the upper part of the support rod 204, and the protruding positions on both sides of the front end of the mounting support plate 302 are slidably installed on the circumferential surface of the slide bar 303, as shown in FIG. Figure 4 shown.

[0041] Therefore, during use, the output shaft of the stepper motor 3 rotates with the second screw rod 301, so that the mounting support plate 302 can rotate synchronously. However, due to the limitation of the sliding rod 303, the mounting support plate 302 cannot rotate synchronously with the second screw rod 301, so that the mounting support plate 302 can only move horizontally back and forth.

[0042] In addition, an information processor 304 is fixedly installed on the upper end surface of the mounting support plate 302, and a human body scanner 305 is fixedly installed on the lower end surface. The human body scanner 305 can scan the structure of the human body in real time, and then transmit the scanned information to the inside of the information processor 304. Then, under the action of the information processor 304, the image of the human body structure can be presented on the screen in real time, which is convenient for doctors to perform puncture operations.

[0043] Secondly, three vertical poles are fixedly installed on the circumferential surface of the mounting support plate 302, and the first motor 401 in the positioning assembly 4 is fixedly installed on the outer side of one end of the three vertical poles away from the center of the mounting support plate 302, and the first adjusting rod 402 is fixedly installed on the output shaft of the first motor 401, and a rotating rod 403 is rotatably installed from one end to the other end of the lower part of the first adjusting rod 402, wherein the two ends of the rotating rod 403 are concave structures, such as Figure 5 shown.

[0044] Then, the second adjusting rods 404 are rotatably mounted at both ends of the rotating rod 403, wherein the second motors 405 are rotatably mounted on the inner sides of the lower ends of the two adjacent second adjusting rods 404. Figure 5As shown, a second arc-shaped slide bar 407 is fixedly installed between the left and right second motors 405, and a first arc-shaped slide bar 406 is fixedly installed on the output shaft of the second motor 405 at the rear end position, wherein the diameter of the first arc-shaped slide bar 406 is larger than that of the second arc-shaped slide bar 407, and the inner side surface of the first arc-shaped slide bar 406 and the outer side surface of the second arc-shaped slide bar 407 are in a fitted state, as shown in FIG. Figure 7 shown.

[0045] During use, when the output shafts of multiple first motors 401 rotate outward synchronously with the first adjusting rod 402, the second adjusting rod 404 can be changed from a tilted state to a relatively horizontal state. Conversely, when the output shafts of the first motors 401 rotate inward with the first adjusting rod 402, the second adjusting rod 404 can be changed from a tilted state to a relatively vertical state.

[0046] Therefore, the first arc-shaped sliding bar 406 and the second arc-shaped sliding bar 407 can perform vertical linear motion during the rotation of the second adjusting rod 404 .

[0047] Secondly, during use, when the first motor 401 at the rear end is started, the first arc-shaped slide bar 406 and the second arc-shaped slide bar 407 can move to between and outside the left and right first adjustment rods 402 .

[0048] On the contrary, starting the first motor 401 on the left side can move the first arc-shaped slide bar 406 and the second arc-shaped slide bar 407 to the lower end of the first adjustment rod 402 on the right end, while starting the first motor 401 on the right end has the opposite effect to the above. Therefore, during use, targeted positioning operations can be performed according to different patient conditions.

[0049] Then, an arc slide 408 is slidably mounted on the inner side of the first arc slide bar 406 and the second arc slide bar 407, but a threaded through rod 409 is fixedly mounted on the upper and lower arc slides 408, wherein the lower end of the threaded through rod 409 penetrates the upper and lower arc slides 408, as shown in FIG. Figure 8 As shown, the threaded through rod 409 is in a through state from the top to the lower end surface, and a thread is provided on its outer circumferential surface, and a groove swivel 410 is installed on the outer circumferential surface of the threaded through rod 409 by means of thread rotation. The groove swivel 410 can rotate on the outer circumferential surface of the threaded through rod 409, and can move up and down along the path of the thread during the rotation process, and its effect is the same as the cooperation effect of the screw and the nut.

[0050] Then, a ring 411 is rotatably mounted on the circumferential surface of the groove rotating ring 410, and long rods 412 are evenly rotatably mounted on the outer circumferential surface of the ring 411 in an annular array. Fig. 9As shown, it should be noted that, during the rotation of the groove rotating ring 410 , the ring 411 will not rotate synchronously with the groove rotating ring 410 .

[0051] In addition, a connecting rod 414 is fixedly installed on the outer side of the lower end opening of the threaded through rod 409, wherein the number of the connecting rods 414 is four, and an expansion plate 413 is rotatably installed at the lower end of each connecting rod 414, wherein the four expansion plates 413 are combined together to form a truncated cone structure, such as Fig. 9 As shown, the lower ends of the long rods 412 are rotatably connected to the outer side surfaces of the corresponding expansion plates 413 .

[0052] During use, the output shafts of the two left and right first motors 401 rotate synchronously with the second arc-shaped slide bar 407. When the second arc-shaped slide bar 407 rotates, the threaded through rod 409 can rotate forward and backward, thereby changing the inclination angle of the threaded through rod 409. Conversely, starting the rear end of the first motor 401 can rotate synchronously with the first arc-shaped slide bar 406. When the first arc-shaped slide bar 406 rotates, the angle of the threaded through rod 409 can be adjusted left and right.

[0053] Secondly, when the groove rotating ring 410 rotates, there are two states of upward movement or downward movement. When moving upward, it can move synchronously with the circular ring 411, and the upward movement of the circular ring 411 can move synchronously with the long rod 412, so that when the long rod 412 moves upward, the lower end of the expansion plate 413 can be opened outward. On the contrary, when the groove rotating ring 410 moves downward, the circular ring 411 can move downward with the long rod 412, so that the lower end of the expansion plate 413 can be tightly fitted together, thereby realizing a micro-expansion operation on the patient's incision.

[0054] Working principle: First, the lower end surface of the convex slide rod 1 fits with the upper end surface of the operating table near the edge, and the knob 103 is turned, and the knob 103 rotates synchronously with the first screw 102, so that the first screw 102 with the gasket 104 fits tightly with the lower end surface of the operating table.

[0055] Then the servo motor 106 at the left or right end is started, and the output shaft of the servo motor 106 rotates synchronously with the screw 105, so that the slide 107 can slide to the left or right.

[0056] During the sliding process of the slide 107, the cavity rod 2 can be rotated synchronously. Then, the dual-axis motor 201 is started, and the output shaft of the dual-axis motor 201 rotates the first adjustment plate 202. When the first adjustment plate 202 rotates, it can drive the second adjustment plate 203 to rotate synchronously, and the second adjustment plate 203 can drive the support rod 204 to move upward.

[0057] At this time, the support rod 204 can move synchronously with the stepper motor 3 when moving, and the stepper motor 3 can move the second screw rod 301 synchronously upward, and then the second screw rod 301 can move the mounting support plate 302 synchronously upward.

[0058] At this time, the stepper motor 3 is started, and the output shaft of the stepper motor 3 rotates synchronously with the second screw rod 301 . When the second screw rod 301 rotates, the mounting support plate 302 can move forward and backward under the restriction of the slide rod 303 .

[0059] The human body scanner 305 is started, and the human body scanner 305 transmits the scanned human body structure to the information processor 304, and the information processor 304 can transmit the collected information to the screen for display.

[0060] Finally, the position of the threaded through rod 409 can be adjusted in real time under the action of the first motor 401 in the positioning assembly 4 .

[0061] Secondly, the first arc-shaped slide bar 406 and the second arc-shaped slide bar 407 can be rotated under the action of the second motor 405, and the tilt angle of the threaded penetrating rod 409 can be adjusted during the rotation, thereby changing the tilt angle of the puncture needle.

[0062] Secondly, under the action of the groove rotating ring 410, the circular ring 411 can move up and down with the long rod 412, so that the expansion plate 413 can expand the incision at the position where the patient needs to be punctured.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
