Abstract
Description
Technical Field
[0001] The present invention relates to an ultrasound-guided puncture technology, and in particular to an ultrasound-guided puncture fixation device that is user-friendly and can be adjusted at multiple angles. Background Art
[0002] Ultrasound aspiration is a technique that uses ultrasound to guide puncture procedures. Under ultrasound guidance, doctors use an ultrasound probe to observe the patient's tissue structure and organ position in real time, ensuring the accuracy and safety of the puncture procedure. Ultrasound aspiration is commonly used to guide the extraction of tissue samples or the drainage of fluids. For example, in medicine, ultrasound-guided puncture procedures can be used for biopsies, cytology, and cyst fluid extraction. This technology helps doctors accurately locate the area requiring surgery while minimizing the risk of damaging surrounding tissue.
[0003] In actual application, the operator usually needs to hold the ultrasound probe with one hand and move it on the human skin to detect different organ locations; at the same time, the other hand holds the puncture needle and performs puncture at the appropriate position. This method limits the operator's flexibility, as both hands are occupied at the same time, making it inconvenient to use. In addition, when performing detection, the position of the puncture needle is easily deviated because the coordination of the two hands is often not unified. Summary of the Invention
[0004] In order to solve the problems existing in the above-mentioned technology, the present invention provides a device that can move the ultrasonic head and the puncture needle with one hand, thereby facilitating the operation process of medical personnel.
[0005] The present invention provides a multi-angle adjustable ultrasound-guided puncture and fixation device, which includes an ultrasonic mobile gun and a puncture assembly;
[0006] The ultrasonic mobile gun has a gripping rod portion, and the bottom of the gripping rod portion is provided with an ultrasonic head;
[0007] The puncture assembly is arranged at a lower position on the side of the holding rod, and the puncture assembly has a driving member and an angle adjustment clamping member, and the angle adjustment clamping member has a fixed frame, a left elastic splint, a right elastic splint, and angle adjustment cams arranged at multiple positions, a left elastic splint and a right elastic splint are arranged inside the fixed frame, a clamping channel is formed between the left elastic splint and the right elastic splint, the puncture needle main body rod is placed in the clamping channel, and the angle adjustment cam is arranged at the side position of the left elastic splint and the right elastic splint; the driving member is used to drive the angle adjustment clamping member to reciprocate up and down for puncture.
[0008] The beneficial effects of the above scheme are as follows: the operator moves the ultrasonic mobile gun with their hand, and the ultrasonic head detects the user's skin to achieve positioning. When puncture is required, the puncture assembly is activated, and the automatic button can be manually controlled to activate the operation, causing the driver to drive the angle adjustment clamp and the puncture needle body to perform puncture. In addition, the puncture needle body is fixed by the left and right elastic clamps, and the angle adjustment cam is activated by button control to rotate the angle adjustment cam in a specific position. This not only better clamps the puncture needle body in the middle position, but also allows the angle of the elastic clamp in the middle position to be adjusted by rotating the angle adjustment cam, thus adjusting the placement angle of the puncture needle, thus allowing the puncture angle position to be quickly adjusted as needed. More importantly, the puncture assembly and ultrasonic probe are integrated into one, allowing single-handed operation. Both components can be moved simultaneously, and when puncture is required, they can be quickly controlled by a button, which is very convenient.
[0009] Preferably, the angle adjustment cams are connected to the angle drive motor, and there are four groups of angle adjustment cams, two groups of angle adjustment cams are arranged on the left side of the left elastic clamping plate, and the other two groups of angle adjustment cams are arranged on the right side of the right elastic clamping plate.
[0010] Angle adjustment cams are provided above and below both sides, which can better fix the puncture needle, and the angle placement of the puncture needle can be controlled by controlling the angle adjustment cam at a specific position, which has a better application effect.
[0011] Preferably, the driving member includes a driving motor, a driving eccentric, a driving handle and a driving rod, the driving motor is connected to the driving eccentric, the driving eccentric is rotatably set on the fixed plate, the middle part of the driving handle is swingably hinged to the fixed plate, one end of the driving handle cooperates with the driving eccentric through a rotating roller, the bottom of the driving handle on the side close to the rotating roller is connected to the fixed plate through a spring structure, the other end of the driving handle is hinged to the driving rod, the bottom of the driving rod is hinged to the fixed frame, and the fixed frame is slidably set in the limit frame.
[0012] When the puncture needle needs to be pressed, the drive motor provides power to the drive eccentric wheel to drive the drive handle to move, which in turn causes the drive rod to move up and down, thereby causing the fixed frame to move up and down, driving the puncture needle in the middle position to perform puncture. In addition, the fixed frame slides within the limit frame to make the puncture process more stable.
[0013] Preferably, the drive handle has an adjustment opening, an adjustment screw is disposed in the adjustment opening, one side of the adjustment screw is connected to the adjustment motor, the adjustment screw has an adjustment slider, the side of the adjustment slider slidably engages with the inner wall of the adjustment opening, and the drive rod is hinged to the adjustment slider. The position of the adjustment slider is adjusted by movement of the adjustment screw, thereby changing the connection point of the drive rod on the drive handle. When the drive handle swings, the amplitude of the up and down movement of the drive rod is adjusted, and the amplitude or depth of the puncture is correspondingly changed.
[0014] Preferably, the fixing plate is connected and fixed to the limiting frame via a connecting plate.
[0015] Preferably, the ultrasonic moving gun is moved by operating the gripping rod; the puncture assembly is controlled by an electric button, that is, the angle adjustment cam is activated to rotate the angle adjustment cams at different positions, thereby driving the left elastic splint or the right elastic splint to move, on the one hand, clamping the puncture needle main body rod in the middle position, and on the other hand, adjusting the placement angle of the left elastic splint or the right elastic splint as needed to adjust the puncture angle of the puncture needle.
[0016] Preferably, when the angle adjustment cam at the left side of the left elastic clamp is rotated, the left elastic clamp is driven to move, and when the angle adjustment cam at the right side of the right elastic clamp is rotated, the right elastic clamp is driven to move, so as to adjust to a suitable angle position.
[0017] Preferably, the driving motor provides power to rotate the driving eccentric wheel. When the driving eccentric wheel rotates, it contacts the rotating roller and forces the driving handle to move. The driving handle realizes a lever-like swinging action, and then drives the fixed frame to move up and down through the driving rod, and is reset by the spring structure.
[0018] Preferably, the adjusting motor provides power to move the adjusting screw rod, which causes the adjusting slider to move along the adjusting opening, thereby adjusting the lifting range of the driving rod and correspondingly adjusting the lifting range of the fixed frame.

[0029] The ultrasonic mobile gun 10 has a gripping rod 11 , and an ultrasonic head 12 is provided at the bottom of the gripping rod 11 ;
[0030] The puncture assembly 20 is arranged at the lower side of the holding rod 11, and the puncture assembly 20 has a driving member 30 and an angle adjustment clamping member 40. The angle adjustment clamping member 40 has a fixed frame 41, a left elastic splint 42, a right elastic splint 43, and angle adjustment cams 44 arranged at multiple positions. The left elastic splint 42 and the right elastic splint 43 are arranged inside the fixed frame 41, and a clamping channel is formed between the left elastic splint 42 and the right elastic splint 43. The puncture needle main body rod 45 is placed in the clamping channel, and the angle adjustment cam 44 is arranged at the side position of the left elastic splint 42 and the right elastic splint 43; the driving member 30 is used to drive the angle adjustment clamping member 40 to reciprocate up and down for puncture.
[0031] In addition, the puncture assembly 20 preferably has a housing 61 with a plurality of buttons 62 on the housing 61. By controlling the buttons 62, selective control of the driving member 30 or the plurality of angle adjustment cams 44 can be achieved.
[0032] The operator holds the ultrasonic mobile gun and moves it, using the ultrasonic head 12 to detect and locate the user's skin. When a puncture is required, the puncture assembly 20 is activated, and the automatic button 62 can be manually controlled to activate the operation, causing the driver 30 to drive the angle adjustment clamp and the puncture needle body to perform the puncture movement. Furthermore, the puncture needle body is secured by the left and right elastic clamps 42 and 43. The angle adjustment cam 44 is activated by a button to rotate the angle adjustment cam 44 at a specific position. This not only better clamps the puncture needle body in the middle position, but also allows the angle of the elastic clamp in the middle position to be adjusted by rotating the angle adjustment cam 44, thus adjusting the placement angle of the puncture needle 49. This allows for quick adjustment of the puncture angle position as needed. More importantly, the puncture assembly 20 and the ultrasonic probe are integrated into one, allowing single-handed operation. Both components can move simultaneously, and when a puncture is required, the button can be quickly controlled for quick control, making it very convenient.
[0033] The ultrasonic moving gun 10 is moved by operating the gripping rod 11; the puncture assembly 20 is controlled by the electric button, that is, the angle adjustment cam 44 is started to rotate the angle adjustment cam 44 at different positions to drive the left elastic splint 42 or the right elastic splint 43 to move, on the one hand, clamping the puncture needle main rod 45 in the middle position, and on the other hand, adjusting the placement angle of the left elastic splint 42 or the right elastic splint 43 as needed to adjust the puncture angle of the puncture needle 49.
[0034] Second embodiment:
[0035] Based on the first embodiment, in this embodiment, the angle adjustment cams 44 are connected to the angle drive motor 46. The angle adjustment cams 44 are provided in four groups, two of which are arranged on the left side of the left elastic clamping plate 42, and the other two groups of angle adjustment cams 44 are arranged on the right side of the right elastic clamping plate 43. In addition, multiple groups of angle adjustment cams 44 can be provided on both sides in the vertical direction, and each group of angle adjustment cams 44 can be individually controlled to achieve different angles of placement to adjust the angle of the puncture needle.
[0036] Angle adjustment cams 44 are provided above and below both sides, which can better fix the puncture needle, and the angle of the puncture needle can be controlled by controlling the angle adjustment cam 44 at a specific position, which has a better application effect.
[0037] When the angle adjustment cam 44 at the left side of the left elastic clamping plate 42 rotates, the left elastic clamping plate 42 is driven to move, and when the angle adjustment cam 44 at the right side of the right elastic clamping plate 43 rotates, the right elastic clamping plate 43 is driven to move to adjust to a suitable angle position.
[0038] Third embodiment:
[0039] In a further preferred embodiment, the driving member 30 of this embodiment includes a driving motor 31, a driving eccentric wheel 32, a driving handle 33 and a driving rod 34, the driving motor 31 is connected to the driving eccentric wheel 32, the driving eccentric wheel 32 is rotatably set on the fixed plate 35, the middle part of the driving handle 33 is swingably hinged to the fixed plate 35, one end of the driving handle 33 cooperates with the driving eccentric wheel 32 through a rotating roller 36, the bottom of the driving handle 33 on the side close to the rotating roller 36 is connected to the fixed plate 35 through a spring structure 37, the other end of the driving handle 33 is hinged to the driving rod 34, the bottom of the driving rod 34 is hinged to the fixed frame 41, and the fixed frame 41 is slidably set in the limit frame 38.
[0040] When the puncture needle needs to be pressed, the drive motor 31 provides power to the drive eccentric 32, which drives the drive handle 33 to move. That is, the drive eccentric 32 has different contour edges, and through contact with the rotating roller 36, the drive handle 33 moves, which in turn causes the drive rod 34 to move up and down, thereby causing the fixed frame 41 to achieve a lifting movement, driving the puncture needle in the middle position to achieve a puncture movement. In addition, the fixed frame 41 slides within the limit frame 38 to make the puncture process more stable.
[0041] The driving handle 33 has an adjustment opening 51, in which an adjustment screw 52 is disposed. One side of the adjustment screw 52 is connected to the adjustment motor 53. The adjustment screw 52 has an adjustment slider 54. The side of the adjustment slider 54 slidably engages with the inner wall of the adjustment opening 51. The driving rod 34 is hinged to the adjustment slider 54. The position of the adjustment slider 54 is adjusted by the movement of the adjustment screw 52, thereby changing the connection point of the driving rod 34 on the driving handle 33. Therefore, when the driving handle 33 swings, the amplitude of the up and down movement of the driving rod 34 is adjusted, and the amplitude or depth of the puncture is correspondingly changed.
[0042] The fixing plate 35 is connected and fixed to the limiting frame 38 via a connecting plate 57 .
[0043] The driving motor 31 provides power to rotate the driving eccentric wheel 32. When the driving eccentric wheel 32 rotates, it contacts the rotating roller 36 and forces the driving handle 33 to move. The driving handle 33 performs a lever-like swinging action, and then drives the fixed frame 41 to move up and down through the driving rod 34, and is reset by the spring structure 37.
[0044] The adjusting motor provides power to move the adjusting screw rod, which in turn moves the adjusting slider along the adjusting opening, thereby adjusting the lifting range of the driving rod 34 and correspondingly adjusting the lifting range of the fixing frame 41 .
