Description

Technical Field

[0001] The present invention relates to the field of neurology instruments, and particularly to an interventional vascular puncture positioning device for interventional use. Background Art

[0002] In neurology interventional therapy, vascular interventional puncture (also known as vascular interventional puncture technique) is a key technical means for entering the body through blood vessels to diagnose and treat various nervous system-related diseases. Vascular interventional puncture is a minimally invasive surgical technique for entering the body through blood vessels for diagnosis or treatment. In the field of neurology interventional, usually by puncturing the femoral artery or the radial artery, a catheter is guided to the cerebral blood vessels or other relevant parts for imaging examination or implementation of treatment operations.

[0003] Currently, when performing puncture treatment on patients with neurology vascular diseases, generally a puncture needle is directly inserted into the blood vessel, and then a catheter is inserted into the blood vessel for treatment. However, in the existing implementation stage, after the hollow needle punctures, the needle tip enters the blood vessel, but the part of the needle tube is in a suspended state. Therefore, when inserting other objects such as a catheter, it is necessary to hold the hollow needle by hand, so an additional doctor is required to continuously hold the needle tube during the vascular surgery. Without holding by hand, the hollow needle will shake, and the hollow needle inserted into the blood vessel will cause discomfort to the patient.

[0004] Although some existing positioning devices can solve the problem of positioning and supporting the puncture hollow needle, it is difficult to well adjust the puncture angle during use, and there are still inconveniences in use.

[0005] Therefore, to solve the above problems, an interventional vascular puncture positioning device for interventional use is proposed. Summary of the Invention

[0006] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an interventional vascular puncture positioning device for interventional use, which realizes the auxiliary positioning of the puncture needle through the positioning device, thereby ensuring the stability of the puncture needle during the puncture process and reducing the hand-holding actions of medical staff.

[0007] The above technical object of the present invention is achieved through the following technical solutions:

[0008] An interventional vascular puncture positioning device for interventional use includes two groups of positioning structures; the two groups of the positioning structures are arranged in a cross-shaped intersection, and one group of the positioning structures is assembled on the other group of the positioning structures;

[0009] One set of the positioning structures is equipped with a moving platform. A positioning block is fixedly arranged on the side surface of the moving platform. A mounting shaft is vertically supported on the upper end surface of the positioning block. A damping universal ball head is assembled at the top of the mounting shaft. A locking sleeve is assembled on the damping universal ball head.

[0010] A limit seat is assembled on the back surface of the other set of the positioning structures.

[0011] Wherein, the locking sleeve is in a columnar shape and through holes are formed through both ends thereof. A blood vessel intervention puncture needle for neurological intervention is movably arranged in the locking sleeve.

[0012] A locking clamp block is sleeved outside the mounting shaft. An ultrasonic detection module is installed on the locking clamp block.

[0013] The positioning structure includes an adjusting seat which is in a U shape and has perpendicular sides on both sides. Two optical rods are arranged in the adjusting seat. A slider is sleeved outside the two optical rods together.

[0014] Further, a threaded hole is formed on the side surface of the slider. The moving platform is detachably installed on the slider of one set of the positioning structures through a bolt member. The vertically arranged positioning structure is assembled on the slider of the horizontally arranged positioning structure.

[0015] Further, a plurality of second locking bolts are threadedly connected to the locking sleeve. The ends of the plurality of second locking bolts penetrate through the locking sleeve and extend into the through holes. Anti-slip threads are formed at the ends of each of the second locking bolts. A first locking bolt is also threadedly connected to the damping universal ball head.

[0016] Further, the positioning structure further includes a threaded lead screw rotatably arranged on the adjusting seat. The threaded lead screw penetrates through the slider and is threadedly connected thereto. One end of the threaded lead screw penetrates through the adjusting seat and extends outside the adjusting seat to be connected with a rotating shaft handle.

[0017] Further, the limit seat is in a U-shaped structure and is assembled on the back surface of the horizontally arranged adjusting seat. A clamping groove is formed on the limit seat.

[0018] Further, a plurality of third locking bolts are threadedly connected to the upper end surface of the limit seat. The end of each of the third locking bolts penetrates through the upper end surface of the limit seat and extends into the clamping groove.

[0019] Further, the locking clamp block includes a locking block and a rotating block. The rotating block is connected to the locking block through a bolt. The rotating block can be adjusted in angle on the locking block.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. In actual use, through the locking of the damping universal ball head by the first locking bolt and the locking of the vascular intervention puncture needle for neurology intervention by the locking sleeve, when the vascular intervention puncture needle for neurology intervention accurately penetrates into the patient's body, the locking mechanism of the damping universal ball head and the locking sleeve can ensure that the vascular intervention puncture needle for neurology intervention remains stationary at the predetermined position, and medical staff do not need to continuously hold the puncture needle, thus liberating both hands.

[0022] 2. The two groups of positioning structures arranged in a cross shape can achieve double-position adjustment of the mobile platform in the horizontal and vertical directions. When the mobile platform is performing linear position adjustment, the erection shaft, damping universal ball head, and locking sleeve installed on the mobile platform can follow for position adjustment. Moreover, through the cooperation of the damping universal ball head, the locking sleeve can drive the vascular intervention puncture needle for neurology intervention to be adjusted at multiple angles. This flexibility allows medical staff to quickly adjust the position of the vascular intervention puncture needle for neurology intervention according to the specific body position of the patient, the puncture target, and the surgical needs, ensuring that the puncture operation can adapt to complex treatment requirements.

[0023] 3. The provided ultrasonic detection module 9 can provide real-time image feedback, helping doctors dynamically observe the movement trajectory of the puncture needle to ensure that the needle tip accurately reaches the target area. At the same time, it can display the surrounding anatomical structures in real time, such as the positions of blood vessels, nerves, and organs, to avoid accidentally injuring important tissues. Using the ultrasonic imaging of the ultrasonic detection module 9, doctors can also accurately locate the lesion site or target tissue, improve the accuracy of puncture, and reduce the risk of blind puncture.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Among them, the same parts are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0031] First embodiment;

[0032] Refer to Figures 1-4 As shown, a vascular interventional puncture positioning device for intervention in the present invention in a preferred embodiment includes two groups of positioning structures 1; the two groups of positioning structures 1 are arranged in a cross shape, and one group of positioning structures 1 is assembled on the other group of positioning structures 1;

[0033] A moving table 2 is assembled and arranged on one group of positioning structures 1, a positioning block 3 is fixedly arranged on the side surface of the moving table 2, a mounting shaft 4 is vertically supported on the upper end surface of the positioning block 3, a damping universal ball head 5 is assembled at the top of the mounting shaft 4, and a locking sleeve 6 is assembled and arranged on the damping universal ball head 5;

[0034] A limiting seat 100 is assembled and arranged on the back surface of the other group of positioning structures 1;

[0035] Among them, the locking sleeve 6 is in a columnar shape and through holes are opened through both ends thereof, and a blood vessel interventional puncture needle 7 for neurology intervention is movably arranged in the locking sleeve 6;

[0036] A locking clamp block 8 is sleeved outside the mounting shaft 4, and an ultrasonic detection module 9 is installed on the locking clamp block 8;

[0037] The positioning structure 1 includes an adjusting seat 11, the adjusting seat 11 is in a U shape and both sides are perpendicular, and two optical rods 12 are arranged in the adjusting seat 11, and a slider 13 is sleeved outside the two optical rods 12 together.

[0038] In this embodiment, when the blood vessel interventional puncture needle 7 for neurology intervention accurately penetrates into the patient's body, the locking mechanism of the damping universal ball head 5 and the locking sleeve 6 can ensure that the blood vessel interventional puncture needle 7 for neurology intervention remains stationary at a predetermined position, and medical personnel do not need to continuously hold the puncture needle, so that both hands can be liberated.

[0039] After both hands are liberated, medical personnel can perform the next operation, such as catheter intervention, more quickly, thereby reducing unnecessary operation time and improving the fluency and efficiency of the overall treatment process.

[0040] Furthermore, the two groups of positioning structures 1 arranged in a cross shape can achieve double position adjustment of the mobile station 2 in the horizontal and vertical directions. When the mobile station 2 performs linear position adjustment, the erection shaft 4, the damping universal ball head 5, and the locking sleeve 6 installed on the mobile station 2 can follow for position adjustment. Moreover, through the cooperation of the damping universal ball head 5, the locking sleeve 6 can drive the vascular intervention puncture needle 7 for neurology intervention to be adjusted at multiple angles. This flexibility allows medical staff to quickly adjust the position of the vascular intervention puncture needle 7 for neurology intervention according to the specific body position of the patient, the puncture target, and the surgical needs, ensuring that the puncture operation can adapt to complex treatment requirements.

[0041] At the same time, when performing some punctures with special angles or greater difficulties, the combined position adjustment of the positioning structure 1 and the damping universal ball head 5 can very conveniently adjust the angle and depth of the vascular intervention puncture needle 7 for neurology intervention. Especially for areas such as the abdomen, chest, or neck that are difficult to access, it can provide an accurate and comfortable operating space.

[0042] Furthermore, the set ultrasonic detection module 9 can provide real-time image feedback, helping doctors dynamically observe the movement trajectory of the puncture needle, ensuring that the tip of the needle accurately reaches the target area. At the same time, it can also display the surrounding anatomical structures in real time, such as the positions of blood vessels, nerves, and organs, to avoid accidentally injuring important tissues. Using the ultrasonic imaging of the ultrasonic detection module 9, doctors can also accurately locate the lesion site or target tissue, improve the accuracy of puncture, and reduce the risk of blind puncture.

[0043] It should be noted that the set ultrasonic detection module 9 is an existing mature equipment component. It uses a high-resolution, portable ultrasonic probe and has various ultrasonic imaging modes, such as B-mode, color Doppler, etc., for real-time acquisition of ultrasonic image information of the target blood vessel and surrounding tissues. In a preferred embodiment, the ultrasonic detection module 9 is connected through a locking clamp 8. The locking clamp 8 can flexibly adjust the position and angle of the probe by loosening the bolt, accurately align with the puncture site, and can lock the position during the operation to ensure stable imaging. In another preferred embodiment, the locking clamp 8 can be replaced with a robotic arm structure.

[0044] The ultrasonic detection module 9 also includes an image processing and analysis unit: It is electrically connected to the ultrasonic detection module and can be used to receive ultrasonic image data. It has built-in advanced image recognition algorithms and can quickly and accurately identify the contour, direction, diameter size, and depth information of the target blood vessel. The image processing and analysis unit of the ultrasonic detection module 9 is an existing mature control method.

[0045] According to the recognition results, combined with the preset human anatomical model database, an optimal puncture path plan is automatically generated, and the path information is superimposed and displayed on the ultrasonic real-time image in a visual form such as a three-dimensional stereoscopic image, a guiding line, etc., providing intuitive and accurate puncture guidance for doctors.

[0046] It should be noted that during the puncture of the patient, medical staff can take anesthesia measures to make the patient still, and at the same time, medical bandages can also be used to bind and position the affected area of the patient, so as to ensure the stability of the patient's body during the puncture process.

[0047] Second Embodiment;

[0048] Referring to Figure 1 and Figure 4 As shown, a threaded hole is provided on the side of the slider 13; the moving table 2 is detachably installed on the slider 13 of one set of positioning structures 1 through a bolt member; the vertically arranged positioning structure 1 is assembled on the slider 13 of the horizontally arranged positioning structure 1. The threaded hole provided on the slider 13 can be matched with the bolt member on the moving table 2, so as to realize the detachable installation of the moving table 2 on the slider 13.

[0049] Furthermore, by assembling the vertically arranged positioning structure 1 on the slider 13 of another set of horizontally arranged positioning structures 1, the user can adjust the horizontal position of the slider 13, so that the vertically arranged positioning structure 1 moves horizontally.

[0050] Third Embodiment;

[0051] Referring to Figures 1-3 As shown, a plurality of second locking bolts 61 are threadedly connected to the locking sleeve 6. The ends of the plurality of second locking bolts 61 penetrate through the locking sleeve 6 and extend into the through hole. Anti-slip threads are provided at the ends of each second locking bolt 61. A first locking bolt 51 is also threadedly connected to the damping universal ball head 5. The user inserts the blood vessel intervention puncture needle 7 for neurology intervention into the locking sleeve 6 and makes its bottom end pass out from the bottom of the locking sleeve 6. Then the user can tighten the second locking bolt 61 on the locking sleeve 6, so as to lock the blood vessel intervention puncture needle 7 for neurology intervention by using the second locking bolt 61.

[0052] Furthermore, when the blood vessel intervention puncture needle 7 for neurology intervention is locked, at this time the user can loosen the first locking bolt 51. At this time, under the universal connection of the damping universal ball head 5, the blood vessel intervention puncture needle 7 for neurology intervention can follow the locking sleeve 6 to complete universal rotation. When the position of the blood vessel intervention puncture needle 7 for neurology intervention is adjusted, at this time the user tightens the first locking bolt 51 and makes it tightly abut against the ball head of the damping universal ball head 5. At this time, the set damping universal ball head 5 can be in a locked state.

[0053] Furthermore, the provided damping universal ball head 5 itself has damping properties and can maintain its own damping lock during universal movement. By locking the position of the ball head of the damping universal ball head 5 with the first locking bolt 51, it is possible to prevent the ball head of the damping universal ball head 5 from accidentally moving or deviating from the predetermined path during the treatment process, thereby reducing the risk of injury and improving the safety of the surgery. In a preferred embodiment, the provided damping universal ball head 5 adopts a common universal ball head structure on the market, and the way it cooperates with the bolt for locking is also an existing technology.

[0054] Fourth Embodiment;

[0055] Referring to Figure 4 As shown, the positioning structure 1 further includes a threaded lead screw 14 rotatably arranged on the adjusting seat 11. The threaded lead screw 14 passes through the slider 13 and is threadedly connected thereto; one end of the threaded lead screw 14 passes through the adjusting seat 11 and extends to the outside of the adjusting seat 11 and is connected with a rotating shaft handle 15. When the user rotates the rotating shaft handle 15, the threaded lead screw 14 connected to the rotating shaft handle 15 can rotate. When the threaded lead screw 14 rotates, due to the lateral limit of the two optical rods 12 on the slider 13, the slider 13 engaged with the outside of the threaded lead screw 14 can perform a linear motion along the stroke range of the threaded lead screw 14.

[0056] Fifth Embodiment;

[0057] Referring to Figures 1-2 As shown, the limiting seat 100 has a U-shaped structure and is assembled on the back of the horizontally arranged adjusting seat 11. A clamping groove 110 is formed on the limiting seat 100. The provided clamping groove 110 can be used to accommodate the armrest or the bed board of the hospital bed body. When the user inserts the clamping groove 110 into the hospital bed body, the overall installation of the positioning device of the present application can be realized.

[0058] Sixth Embodiment;

[0059] Referring to Figures 1-2 As shown, a plurality of third locking bolts 120 are threadedly connected to the upper end surface of the limiting seat 100. The end of each third locking bolt 120 passes through the upper end surface of the limiting seat 100 and extends into the clamping groove 110. The user aligns the limiting seat 100 with the armrest or the bed board of the hospital bed body and makes the clamping groove 110 clamp the bed body, and then screws the third locking bolt 120. At this time, with the tight contact between the third locking bolt 120 and the hospital bed body, the overall installation of the limiting seat 100 on the hospital bed can be achieved.

[0060] Seventh Embodiment;

[0061] Referring to Figures 1-2As shown, the locking clamp block 8 includes a locking block and a rotating block. The rotating block is connected to the locking block by bolts, and the rotating block can be adjusted in angle on the locking block. The rotating block provided on the locking clamp block 8 can be installed on the locking block by using bolts and nuts, and the locking block is sleeved outside the erection shaft 4. The probe position and angle can be flexibly adjusted through the locking clamp block 8, accurately aligned with the puncture site, and the position can be locked during the operation to ensure stable imaging.

[0062] Specific implementation process:

[0063] First step: When the user needs to perform a puncture operation, first install the positioning device of the present application on the hospital bed. During this period, the user aligns the limit seat 100 with the armrest or the bed board of the hospital bed body and makes the clamping groove 110 clamp the bed body, and then screws the third locking bolt 120 until the third locking bolt 120 clamps the hospital bed body.

[0064] Second step: When the limit seat 100 is limited on the hospital bed body, the user can then install the blood vessel intervention puncture needle 7 for neurology intervention. By inserting the blood vessel intervention puncture needle 7 for neurology intervention into the locking sleeve 6 and making its bottom end pass through the bottom of the locking sleeve 6, the user can then tighten the second locking bolt 61 on the locking sleeve 6, thereby using the second locking bolt 61 to lock the blood vessel intervention puncture needle 7 for neurology intervention.

[0065] Third step: When the blood vessel intervention puncture needle 7 for neurology intervention is locked, the user can then loosen the first locking bolt 51. At this time, under the universal connection of the damping universal ball head 5, the blood vessel intervention puncture needle 7 for neurology intervention can follow the locking sleeve 6 to complete universal rotation; through the assembly of two groups of positioning structures 1 arranged in a cross shape, the moving table 2 installed on one group of positioning structures 1 can also drive the positioning block 3 and the erection shaft 4 to perform horizontal and vertical linear movements. The user can adjust the two groups of positioning structures 1 to make the erection shaft 4 drive the locking sleeve 6 to move to the puncture site of the patient. When the blood vessel intervention puncture needle 7 for neurology intervention moves to the puncture site of the patient, the user can then loosen the second locking bolt 61 to lock the blood vessel intervention puncture needle 7 for neurology intervention, so that the blood vessel intervention puncture needle 7 for neurology intervention is in a movable state. Then hold the blood vessel intervention puncture needle 7 for neurology intervention and make it enter the patient's body. When the blood vessel intervention puncture needle 7 for neurology intervention completes the puncture, the user adjusts the second locking bolt 61 again and locks the blood vessel intervention puncture needle 7 for neurology intervention. At this time, the blood vessel intervention puncture needle 7 for neurology intervention is in a locked state.

[0066] Step 4: When the vascular intervention puncture needle 7 for neurology intervention is punctured and locked, the user can insert the catheter into the vascular intervention puncture needle 7 for neurology intervention at this time, and finally complete the vascular intervention puncture operation for neurology. Through the locking of the damping universal ball head 5 by the first locking bolt 51 and the locking of the vascular intervention puncture needle 7 for neurology intervention by the locking sleeve 6, the vascular intervention puncture needle 7 for neurology and the catheter can always maintain a stable state during the puncture process, thus liberating the hands of medical staff and enabling them to perform other operations smoothly.
