Description

Technical Field

[0001] The invention belongs to the technical field of ultrasonic puncture, and specifically refers to an auxiliary device for ultrasonic-guided puncture of combat trauma. Background Art

[0002] War trauma refers to various body injuries caused directly or indirectly by lethal weapons during combat. In the war trauma treatment environment, a large amount of fluid may accumulate in the body of the wounded, such as peritoneal effusion, pleural effusion, etc., or pus and exudate need to be discharged due to wound infection. Therefore, it is necessary to puncture and drain the fluid accumulated in the body of the wounded (such as blood, pus, exudate, etc.) to relieve pain and reduce the risk of infection. War trauma ultrasound-guided puncture is a method of puncture operation guided by ultrasound technology in emergency battlefields or trauma treatment environments, and is widely used in the process of war trauma treatment.

[0003] The existing ultrasound-guided puncture treatment process is mainly completed manually by the doctor. The doctor holds the ultrasound probe in one hand and the puncture needle in the other. Under the real-time guidance of the ultrasound image obtained by the ultrasound probe, the doctor manually inserts the puncture needle into the patient's body at the location where drainage or biopsy is required. This puncture method has high requirements on the doctor's operating level. Improper operation can easily cause unnecessary damage to the patient and create infection risks. Manual puncture requires the doctor to maintain a high degree of concentration. Long-term puncture work can easily cause doctor fatigue, thereby reducing efficiency.

[0004] Therefore, it is necessary to propose an auxiliary device for combat trauma ultrasound-guided puncture to solve the technical problems existing in the existing ultrasound puncture-assisted process. Summary of the invention

[0016] Furthermore, the model of the controller is Siemens S7-1200.

[0017] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The device is provided with an ultrasonic puncture assembly. The ultrasonic slider can drive the ultrasonic probe to move along the first guide groove, and the puncture slider can drive the treatment puncture needle to slide along the second guide groove. When performing puncture treatment, the second guide groove rotates a certain angle relative to the first guide groove so that the needle tip of the treatment puncture needle points to the detection area of ​​the ultrasonic probe. The treatment puncture needle is gradually inserted into the patient's body driven by the puncture slider. At the same time, the ultrasonic probe is continuously moved driven by the ultrasonic slider to track the position of the needle tip of the treatment puncture needle, and is reflected in the ultrasonic image, so that the treatment puncture needle can be accurately inserted into the position where treatment is required, thereby achieving the technical effect of automatic ultrasound-guided puncture treatment, reducing the extra labor of manual puncture by doctors, saving time and effort, and improving efficiency; (2) During ultrasound-guided puncture, the ultrasound bidirectional adjustment axis, the puncture rotation motor and the puncture adjustment axis can fine-tune the rotation angle of the ultrasound probe and the treatment puncture needle according to actual needs, so that the ultrasound probe and the treatment puncture needle can adapt to different patient surface morphologies to achieve accurate puncture effects of the treatment puncture needle; (3) The puncture needle fixing part plays the role of fixing the treatment puncture needle. The doctor inserts the treatment puncture needle into the rotating sleeve and passes the treatment puncture needle through the puncture needle fixing sleeve. The outer wall of the fixed end sleeve and the inner wall of the rotating sleeve are provided with mutually matching threads. The doctor can rotate the fixed end sleeve to screw the fixed end sleeve into the rotating sleeve to achieve the meshing and fixing of the fixed end sleeve and the rotating sleeve, thereby achieving effective fixation of the treatment puncture needle. The catheter interface can be connected to the drainage tube, so that the fluid accumulated in the patient's body can be smoothly discharged along the treatment puncture needle, the fixed end sleeve, the catheter interface and the drainage tube; (4) The third motor drives the third screw to rotate, so that the puncture slider slides along the second guide groove and moves the treatment puncture needle to achieve the automatic puncture effect of the treatment puncture needle. In order to enable the treatment puncture needle to smoothly puncture into the patient's body, the third screw drives the synchronous gear to rotate together when rotating, and the synchronous gear drives the first adjustment gear to rotate, and the first adjustment gear drives the second adjustment gear to rotate. The rotation directions of the first adjustment gear and the second adjustment gear are opposite. The first adjustment column and the second adjustment column arranged on the upper wall of the first adjustment gear and the second adjustment gear can respectively drive the reciprocating rotation gear to perform periodic reciprocating rotation, so that the coordination gear rod also performs periodic reciprocating rotation. In the process that the puncture needle fixing part gradually moves with the puncture slider, the coordination gear always maintains a meshing state with the coordination gear rod. Driven by the coordination gear rod, the coordination gear also performs periodic reciprocating rotation, thereby causing the treatment puncture needle to perform periodic reciprocating rotation, simulating the action of the doctor twisting the treatment puncture needle during manual puncture, so that the treatment puncture needle can smoothly puncture into the patient's body; (5) The second motor can drive the collar control gear to rotate, and the collar control gear drives the collar rotating gear to rotate, thereby rotating the adjusting rotating collar. The adjusting rotating collar is threadedly connected to the second screw rod. The second screw rod slides relative to the adjusting rotating collar under the rotation of the adjusting rotating collar, thereby causing the second guide groove as a whole to slide relative to the support block. Combined with the sliding distance of the puncture slider relative to the second guide groove, the moving range of the treatment puncture needle is further expanded, which facilitates the flexible adjustment of the position of the treatment puncture needle to meet the needs of different puncture depths; (6) When fixing the ultrasonic probe, the ultrasonic fixing handle can be inserted into the ultrasonic fixing sleeve, and the fixing ribs can be matched with the matching ribs. At this time, the ultrasonic fixing screw shaft is twisted to gradually approach the ultrasonic fixing handle until the end of the ultrasonic fixing screw shaft touches the side wall of the ultrasonic fixing handle. At this time, the ultrasonic fixing handle is fixed under the limitation of the ultrasonic fixing screw shaft and the matching ribs, and it is easy to disassemble and assemble. The wire on the ultrasonic fixing handle can be placed in the wire placement groove to avoid bending, folding, etc. of the wire; (7) The guide rail moving motor can drive the slider gear to rotate. The slider gear slides along the extension direction of the arc guide rail under the limitation of the guide rail ring teeth. The guide rail slider drives the connecting arm to slide, so that the ultrasonic puncture component as a whole slides along the arc guide rail. When performing puncture treatment, the position of the guide rail slider can be adjusted according to the specific puncture position of the patient, so that the ultrasonic puncture component is moved to an angle position suitable for puncture, which is convenient for the subsequent fine-tuning operation of the ultrasonic probe and the treatment puncture needle; (8) The guide rail angle adjustment motor can drive the guide rail seat and the arc guide rail to rotate, so that the arc guide rail can be switched between the vertical state and the horizontal state, which is convenient for the patient to undergo puncture treatment in both lying or sitting states. The inclination angle of the arc guide rail can be adjusted according to actual needs to meet specific treatment requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The control panel 13, the lifting pole 15, the moving wheel 17, the guide rail angle adjustment motor 24, the guide rail movement motor 312, the first telescopic pole 314, the guide groove rotation motor 315, the first motor 322, the puncture rotation motor 323, the second telescopic pole 33, the ultrasonic adjustment motor 332, the ultrasonic probe 35, the second motor 3635, the third motor 3621 and the puncture adjustment motor 3632 are electrically connected to the controller 14 through wires.

[0031] Working principle and workflow: The doctor can control the operation and conversion of each part of the device through the control panel 13, and the controller 14 sends program instructions to each functional structure of the device. Before using the device, the doctor determines whether the patient should adopt a lying or sitting posture for puncture treatment according to the specific situation of the patient. The doctor controls the posture of the arc guide rail 2 through the control panel 13, and the controller 14 controls the guide rail angle adjustment motor 24 to start. The guide rail angle adjustment motor 24 can drive the guide rail seat 22 and the arc guide rail 2 to rotate, so that the arc guide rail 2 can be switched between a vertical state and a horizontal state, which is convenient for the patient to perform puncture treatment in both lying or sitting states. The inclination angle of the arc guide rail 2 can be adjusted according to actual needs to meet specific treatment requirements, such as Figure 2 and Figure 3 shown.

[0032] The patient lies on the nursing bed or sits on the treatment chair according to the doctor's requirements. The doctor first places the device near the nursing bed or treatment chair, and controls the moving wheel 17 to start through the control panel 13. The moving wheel 17 drives the device as a whole to move toward the patient until the ultrasonic puncture assembly 3 moves to the vicinity of the part where the patient needs to be punctured. The doctor first adjusts the position of the ultrasonic puncture assembly 3 according to the part where the patient needs to be punctured. The doctor controls the position of the guide rail slider 31 through the control panel 13. The controller 14 automatically starts the guide rail moving motor 312. The guide rail moving motor 312 can drive the slider gear 311 to rotate. The slider gear 311 slides along the extension direction of the arc guide rail 2 under the limitation of the guide rail ring gear 21. The guide rail slider 31 drives the connecting arm 313 to slide, so that the ultrasonic puncture assembly 3 slides along the arc guide rail 2 as a whole. When performing puncture treatment, the position of the guide rail slider 31 can be adjusted according to the patient's specific puncture position, so that the ultrasonic puncture assembly 3 moves to an angle position suitable for puncture, which is convenient for subsequent fine-tuning operations of the ultrasonic probe 35 and the treatment puncture needle 4.

[0033] When the ultrasonic puncture assembly 3 moves to the position where the patient needs puncture treatment, the doctor stops the guide rail moving motor 312 from continuing to run through the control panel 13, and makes a fine adjustment to the specific posture of the ultrasonic puncture assembly 3. First, the doctor controls the first telescopic pole 314 to start through the control panel 13, so that the first guide groove 32 and the second guide groove 36 gradually approach the patient's body surface. In the initial state, the support block 363 is located at the bottom of the second screw rod 361, and the puncture slider 3623 is located at the top of the third screw rod 362. At this time, the treatment puncture needle 4 is far away from the patient's body surface. Figure 7 As shown, when the ultrasound probe 35 moves to the vicinity of the patient's body surface, the first telescopic pole 314 stops, and the second telescopic pole 33 starts to fine-tune the position of the ultrasound probe 35 until the ultrasound probe 35 contacts the patient's body surface. At this time, the doctor stops the ultrasound probe 35 from continuing to descend through the control panel 13. At this time, the ultrasound image generated by the ultrasound probe 35 is displayed on the control panel 13, and the ultrasound adjustment motor 332 is started at the same time to control the ultrasound bidirectional adjustment shaft 331. The ultrasound bidirectional adjustment shaft 331 can drive the ultrasound probe 35 to rotate in two different directions perpendicular to each other. The doctor continuously adjusts the position of the ultrasound probe 35 according to the ultrasound image until the puncture target in the patient's body is found. At this time, the doctor The patient can control the posture of the treatment puncture needle 4 through the control panel 13 to prepare for the subsequent puncture process. The puncture rotating motor 323 and the puncture adjusting motor 3632 can also drive the second guide groove 36 to rotate in two different directions perpendicular to each other, so that the treatment puncture needle 4 can puncture into the patient's body surface at a suitable angle and direction; in summary, during the ultrasound-guided puncture, the ultrasonic bidirectional adjustment shaft 331, the puncture rotating motor 323 and the puncture adjusting shaft 3631 can fine-tune the rotation angle of the ultrasonic probe 35 and the treatment puncture needle 4 according to actual needs, so that the ultrasonic probe 35 and the treatment puncture needle 4 can adapt to different patient surface morphologies to achieve the precise puncture effect of the treatment puncture needle 4.

[0034] The ultrasonic probe 35 can be removed from the ultrasonic fixing sleeve 341. When fixing the ultrasonic probe 35, the ultrasonic fixing handle 351 can be inserted into the ultrasonic fixing sleeve 341, and the fixing rib 3511 is matched with the matching rib 343. At this time, the ultrasonic fixing screw shaft 342 is twisted to gradually approach the ultrasonic fixing handle 351 until the end of the ultrasonic fixing screw shaft 342 contacts the side wall of the ultrasonic fixing handle 351. At this time, the ultrasonic fixing handle 351 is fixed under the limitation of the ultrasonic fixing screw shaft 342 and the matching rib 343, and the disassembly and assembly are convenient. The wire on the ultrasonic fixing handle 351 can be placed in the wire placement groove 344 to avoid the wire from bending, folding, etc. Similarly, the treatment puncture needle 4 can be removed from the puncture needle fixing part 37, and the puncture needle fixing part 37 plays the role of fixing the treatment puncture needle 4. Before using the present device, the doctor inserts the treatment puncture needle 4 into the rotating sleeve 372 and passes the treatment puncture needle 4 through the puncture needle fixing sleeve 374. The outer wall of the fixed end sleeve 41 and the inner wall of the rotating sleeve 372 are provided with mutually matching threads. The doctor can rotate the fixed end sleeve 41 to screw the fixed end sleeve 41 into the rotating sleeve 372 to achieve the meshing and fixing of the fixed end sleeve 41 and the rotating sleeve 372, thereby achieving effective fixation of the treatment puncture needle 4. The catheter interface 42 can be externally connected to the drainage tube, so that the accumulated fluid in the patient's body can be smoothly discharged along the treatment puncture needle 4, the fixed end sleeve 41, the catheter interface 42 and the drainage tube.

[0035] After the posture adjustment of the ultrasonic probe 35 and the treatment puncture needle 4 is completed, the doctor starts the ultrasound-guided puncture process through the control panel 13. First, the puncture adjustment motor 3632 starts automatically and drives the second guide groove 36 to rotate a certain angle relative to the first guide groove 32, so that the needle tip of the treatment puncture needle 4 points to the detection area of ​​the ultrasonic probe 35. The first motor 322 starts automatically and drives the first screw rod 321 to rotate. The ultrasonic slider 333 slides along the first screw rod 321 as the first screw rod 321 rotates. The ultrasonic slider 333 can drive the ultrasonic probe 35 to move along the first guide groove 32. Similarly, the third motor 3621 drives the third The screw rod 362 rotates, and the puncture slider 3623 moves with the rotation of the third screw rod 362. The puncture slider 3623 can drive the treatment puncture needle 4 to slide along the second guide groove 36. The treatment puncture needle 4 is gradually inserted into the patient's body under the drive of the puncture slider 3623. At the same time, the ultrasonic probe 35 is driven by the ultrasonic slider 333 to continuously move to track the position of the needle tip of the treatment puncture needle 4, and reflect it in the ultrasonic image, so that the treatment puncture needle 4 can accurately puncture the position where treatment is required, thereby achieving the technical effect of automatic ultrasound-guided puncture treatment, reducing the labor process of manual puncture by doctors, saving time and effort, and improving efficiency. In order to enable the treatment puncture needle 4 to smoothly puncture into the patient's body, the third screw rod 362 causes the synchronous gear 3622 to rotate together when rotating, and the synchronous gear 3622 drives the first adjustment gear 3641 to rotate, and the first adjustment gear 3641 drives the second adjustment gear 3643 to rotate. The rotation directions of the first adjustment gear 3641 and the second adjustment gear 3643 are opposite, and the first adjustment column 3642 and the second adjustment column 3644 arranged on the upper wall of the first adjustment gear 3641 and the second adjustment gear 3643 can respectively drive the reciprocating rotation gear 3645 performs periodic reciprocating rotation, causing the coordination gear rod 365 to also perform periodic reciprocating rotation. As the puncture needle fixing part 37 gradually moves along with the puncture slider 3623, the coordination gear 373 always maintains a meshing state with the coordination gear rod 365. Driven by the coordination gear rod 365, the coordination gear 373 also performs periodic reciprocating rotation, thereby causing the treatment puncture needle 4 to perform periodic reciprocating rotation, simulating the doctor's action of twisting the treatment puncture needle 4 during manual puncture, so that the treatment puncture needle 4 can be smoothly punctured into the patient's body.

[0036] The second motor 3635 can drive the collar control gear 3636 to rotate, and the collar control gear 3636 drives the collar rotating gear 3634 to rotate, so that the adjusting rotating collar 3633 rotates, and the adjusting rotating collar 3633 is threadedly connected with the second screw rod 361. The second screw rod 361 slides relative to the adjusting rotating collar 3633 under the rotation of the adjusting rotating collar 3633, so that the second guide groove 36 as a whole slides relative to the support block 363. Combined with the sliding distance of the puncture slider relative to the second guide groove 36, the moving range of the treatment puncture needle 4 is further expanded, which is convenient for flexible adjustment of the position of the treatment puncture needle 4 to meet the needs of different puncture depths.
