[0001] The technical field of the medical device of the present invention, specifically, relates to a puncture positioning device for cerebrovascular intervention in neurology department. Background Art

[0002] Endovascular intervention technology is a newly developed method for preventing and treating cerebrovascular diseases. It has certain advantages compared with traditional treatment methods for cerebrovascular diseases.

[0003] During interventional treatment, it is necessary to fix the puncture needle. When the positioning device in the prior art fixes the puncture sleeve, the effect of automatic centering is not very ideal, and the operation is also rather troublesome. Summary of the Invention

[0004] The present invention provides a puncture positioning device for cerebrovascular intervention in neurology department, which can automatically center the puncture sleeve after determining the basic position, and the fixing operation is simple and easy.

[0005] To this end, the present invention provides a puncture positioning device for cerebrovascular intervention in neurology department, including a base; an adjustment mechanism is slidably provided on the base through a sliding mechanism; a clamping and positioning mechanism for adaptively and continuously clamping and fixing the puncture sleeve is provided on the upper part of the adjustment mechanism; the clamping and positioning mechanism includes a mounting plate connected to the adjustment mechanism, two sets of side clamping components arranged on the mounting plate, and an intermediate abutting component arranged between the two sets of side clamping components, and the two sets of side clamping components are connected to the intermediate abutting component through a linkage component.

[0006] By adopting the above technical solutions: The base is installed on the operating table or the hospital bed to install the entire positioning device. The position of the adjustment mechanism installed through the sliding mechanism can be changed relatively to adapt to the puncture position. By setting the clamping and positioning mechanism, when installing the puncture sleeve, the adaptive positioning and fixing of the puncture sleeve can be realized by pressing down the puncture sleeve. During the fixing process, pressing down the puncture sleeve can cause the two side clamping components and the intermediate abutting component to expand and open outwards simultaneously to form a clamping cavity. When the puncture sleeve enters the clamping cavity, the two sets of side clamping components and the intermediate abutting component reset to realize automatic centering clamping and fixing of the puncture sleeve.

[0007] Optionally, the sliding mechanism includes an arc T-shaped chute arranged on the base, the adjustment mechanism includes an adjustment column slidably arranged at the lower end inside the arc T-shaped chute, a T-shaped slider is arranged at the lower part of the adjustment column, the T-shaped slider is slidably arranged inside the arc T-shaped chute, and a locking component is arranged between the adjustment column and the arc T-shaped chute.

[0008] By adopting the above technical solutions: the arc T-shaped chute can be used to puncture and position the patient's head on the semi-circular circumference, and the adjustment structure can adjust the angle of the device to facilitate adaptation to the puncture position. By setting the locking component, the position of the adjusting column can be relatively locked after the position of the adjusting column is adjusted in place, so as to facilitate assisting in positioning the puncture sleeve.

[0009] Optionally, the locking component includes a locking piece arranged at the lower part of the adjusting column. A threaded hole is provided on the locking piece, and a locking screw is threadedly connected in the threaded hole.

[0010] By adopting the above technical solutions: after the position of the adjusting column is adjusted in place, the adjusting column can be fixed by continuously screwing the locking screw into the threaded hole.

[0011] Optionally, the adjusting column includes a lower rod and an upper rod rotatably connected to the lower rod. An adjusting screw is provided between the upper rod and the lower rod.

[0012] By adopting the above technical solutions: the upper rod can rotate relative to the lower rod, so as to change the swinging direction of the upper rod, and thus can adapt to the puncture position in multiple dimensions. After adjustment, it can be locked by the adjusting screw.

[0013] Optionally, the side clamping component includes two opposite clamping plates slidably arranged on the mounting plate through an elastic component. A guiding clamping block is provided at the upper part of the clamping plate.

[0014] By adopting the above technical solutions: when installing the puncture sleeve, by pressing down the puncture sleeve, the puncture sleeve contacts and pushes the guiding clamping blocks to move away from each other, thereby driving the two mounting plates to compress the elastic component and move away from each other. The two mounting plates drive the intermediate abutting component to move downward through the linkage component, gradually forming a clamping cavity. When the puncture sleeve completely slides past the two guiding clamping blocks, the two mounting plates approach each other, and at the same time the intermediate abutting component also resets to clamp the puncture sleeve.

[0015] Optionally, the intermediate abutting component includes a moving plate arranged on the mounting plate through a telescopic component. Abutting columns are provided on the upper part of the moving plate, and arc-shaped holding pieces for clamping the puncture sleeve are provided on the abutting columns.

[0016] By adopting the above technical solutions: driven by the linkage component, when the two mounting plates move away from each other, the moving plate can be driven to move downward through the linkage component, and at the same time the telescopic component is compressed. When resetting, the two arc-shaped holding pieces clamp the bottom of the puncture sleeve.

[0017] Optionally, the linkage assembly includes a retaining rod. The lower end of the retaining rod is fixed to the mounting plate, and the other end of the retaining rod passes through the moving plate. The linkage assembly further includes a crank and connecting rod hinged to the upper end of the retaining rod. The lower end of the crank and connecting rod abuts against the upper surface of the moving plate, and the other end of the crank and connecting rod is hinged to one end of a pull rod, and the other end of the pull rod is connected to the inner side surface of the clamping plate.

[0018] By adopting the above technical solution: Firstly, the retaining rod can limit the movement of the moving plate so that it can only move up and down. Secondly, the retaining rod is used to install the crank and connecting rod. When the two mounting plates move away from each other, the crank and connecting rod can be swung through the pull rod, so that the crank and connecting rod push the moving plate downward.

[0019] Optionally, the guiding and clamping block includes a downwardly inclined sliding inclined surface portion and a clamping portion provided at the lower part of the sliding inclined surface portion.

[0020] By adopting the above technical solution: By providing the sliding inclined surface portion when pressing down the puncture sleeve, the two guiding and clamping blocks can move away from each other. During the process of the guiding and clamping block returning to its original position, the clamping portion can be used to clamp the upper part of the puncture sleeve.

[0021] Optionally, the elastic assembly includes a fixing plate provided on the mounting plate. One end of a return spring is fixed to the fixing plate, and the other end of the return spring is connected to the clamping plate.

[0022] By adopting the above technical solution: The setting of the return spring can push the two clamping plates to move towards each other for resetting.

[0023] Optionally, the telescopic assembly includes a telescopic rod with one end connected to the mounting plate. The other end of the telescopic rod is connected to the moving plate, and a top spring is sleeved outside the telescopic rod.

[0024] By adopting the above technical solution: The setting of the telescopic rod and the top spring can prompt the moving plate to reset and clamp the bottom of the puncture sleeve.

[0025] The working principle and beneficial effects of the present invention are as follows:

[0026] 1. In the present invention, the base is installed on an operating table or a hospital bed to install the entire positioning device. The position of the adjusting mechanism installed through the sliding mechanism can be changed relatively to adapt to the puncture position. By providing the clamping and positioning mechanism, when installing the puncture sleeve, the self-adaptive positioning and fixation of the puncture sleeve can be achieved by pressing down the puncture sleeve. During the fixing process, pressing down the puncture sleeve can cause the two side clamping assemblies and the middle abutting assembly to expand simultaneously to form a clamping cavity. When the puncture sleeve enters the clamping cavity, the two side clamping assemblies and the middle abutting assembly reset to realize automatic centering clamping and fixation of the puncture sleeve.

[0027] 2. When installing the puncture sleeve, by pressing down the puncture sleeve, the puncture sleeve contacts and pushes the guiding clamping blocks to move away from each other, thereby driving the two mounting plates to compress the elastic components and move away from each other. The two mounting plates drive the intermediate abutting component to move downward through the linkage component, gradually forming a clamping cavity. When the puncture sleeve completely slides past the two guiding clamping blocks, the two mounting plates approach each other, and at the same time the intermediate abutting component also resets, forming a clamp on the puncture sleeve.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0034] Such as Figures 1 - 3As shown in the figure, this embodiment provides a puncture positioning device for cerebrovascular intervention in neurology, including a base 100. The base 100 can be injection-molded, and an adjusting mechanism 300 is slidably arranged on the base 100 through a sliding mechanism 200; a clamping and positioning mechanism 500 for adaptively and continuously clamping and fixing a puncture sleeve 400 is arranged on the upper part of the adjusting mechanism 300; the clamping and positioning mechanism 500 in this embodiment includes a mounting plate 510 connected to the adjusting mechanism 300, two sets of side clamping components 520 arranged on the mounting plate 510, and an intermediate abutting component 530 arranged between the two sets of side clamping components 520. The two sets of side clamping components 520 are connected to the intermediate abutting component 530 through a linkage component 540.

[0035] The basic principle of this embodiment: The base 100 is installed on the operating table or the hospital bed to install the entire positioning device. The position of the adjusting mechanism 300 installed through the sliding mechanism 200 can be changed relatively to adapt to the puncture position. By setting the clamping and positioning mechanism 500, when installing the puncture sleeve 400, the adaptive positioning and fixing of the puncture sleeve 400 can be realized by pressing down the puncture sleeve 400. During the fixing process, pressing down the puncture sleeve 400 can cause the two side clamping components 520 and the intermediate abutting component 530 to expand simultaneously to form a clamping cavity. When the puncture sleeve 400 enters the clamping cavity, the two sets of side clamping components 520 and the intermediate abutting component 530 reset to realize automatic centering clamping and fixing of the puncture sleeve 400.

[0036] In order to facilitate position adjustment to adapt to the puncture position, the sliding mechanism 200 in this embodiment includes an arc T-shaped sliding groove arranged on the base 100. The adjusting mechanism 300 includes an adjusting column 310 with its lower end slidably arranged inside the arc T-shaped sliding groove. A T-shaped slider is arranged at the lower part of the adjusting column 310, and the T-shaped slider is slidably arranged inside the arc T-shaped sliding groove. A locking component is arranged between the adjusting column 310 and the arc T-shaped sliding groove. The setting of the arc T-shaped sliding groove can perform puncture positioning on the patient's head on a semi-circular circumference. The setting of the adjusting structure can adjust the angle of this device to facilitate adaptation to the puncture position. By setting the locking component, the position of the adjusting column 310 can be relatively locked after the position of the adjusting column 310 is adjusted in place, so as to facilitate assisting in positioning the puncture sleeve 400.

[0037] The locking component includes a locking piece 320 arranged at the lower part of the adjusting column 310. A threaded hole 330 is arranged on the locking piece 320, and a locking screw is threadedly connected inside the threaded hole 330. After the position of the adjusting column 310 is adjusted in place, the adjusting column 310 can be fixed by continuously screwing the locking screw into the threaded hole 330.

[0038] The adjusting column 310 in this embodiment includes a lower rod 340 and an upper rod 350 rotatably connected to the lower rod 340. An adjusting screw 360 is provided between the upper rod 350 and the lower rod 340. The upper rod 350 can rotate relative to the lower rod 340, so that the swinging direction of the upper rod 350 can be changed, thereby enabling the puncture position to be adapted in multiple dimensions. After adjustment, it can be locked by the adjusting screw 360.

[0039] The side clamping assembly 520 therein includes two opposite clamping plates 521 slidably arranged on the mounting plate 510 through an elastic assembly. A guiding clamping block 522 is provided on the upper part of the clamping plate 521. When installing the puncture sleeve, by pressing down the puncture sleeve 400, the puncture sleeve 400 contacts and pushes the guiding clamping blocks 522 to move away from each other, thereby driving the two mounting plates 510 to compress the elastic assembly and move away from each other. The two mounting plates 510 drive the intermediate abutting assembly 530 to move downward through the linkage assembly 540, gradually forming a clamping cavity. When the puncture sleeve 400 completely slides past the two guiding clamping blocks 522, the two mounting plates 510 approach each other, and at the same time the intermediate abutting assembly 530 also resets to clamp the puncture sleeve 400.

[0040] The intermediate abutting assembly 530 therein includes a moving plate 531 arranged on the mounting plate 510 through a telescopic assembly. Abutting columns 532 are provided on the upper part of the moving plate 531. Arc-shaped holding pieces 533 for clamping the puncture sleeve 400 are provided on the abutting columns 532. Driven by the linkage assembly 540, when the two mounting plates 510 move away from each other, the moving plate 531 can be driven to move downward through the linkage assembly 540, and at the same time the telescopic assembly is compressed. When resetting, the two arc-shaped holding pieces 533 clamp the bottom of the puncture sleeve.

[0041] Specifically, the linkage assembly 540 in this embodiment includes a retaining rod 541. The lower end of the retaining rod 541 is fixed on the mounting plate 510. The other end of the retaining rod 541 passes through the moving plate 531. It also includes a crank connecting rod 542 hinged to the upper end of the retaining rod 541. The lower end of the crank connecting rod 542 abuts against the upper surface of the moving plate 531. The other end of the crank connecting rod 542 is hinged to one end of a pull rod 543. The other end of the pull rod 543 is connected to the inner side surface of the clamping plate 521. The retaining rod 541 can limit the movement of the moving plate 531 so that it can only move up and down, and is also used to install the crank connecting rod 542. When the two mounting plates 510 move away from each other, the crank connecting rod 542 can be swung through the pull rod 543, so that the crank connecting rod 542 pushes the moving plate 531 downward.

[0042] Specifically, the above-mentioned guiding clamping block 522 includes a downwardly inclined sliding inclined surface portion 523 and a clamping portion 524 provided at the lower part of the sliding inclined surface portion 523. By providing the sliding inclined surface portion 523 when pressing down the puncture sleeve, the two guiding clamping blocks 522 can move away from each other. During the process of the guiding clamping block 522 returning to its original position, the clamping portion 524 can be used to clamp the upper part of the puncture sleeve 400.

[0043] The elastic component of this embodiment includes a fixing plate 525 provided on the mounting plate 510. One end of a return spring 526 is fixed on the fixing plate 525, and the other end of the return spring 526 is connected to the clamping plate 521. The setting of the return spring 526 can push the two clamping plates 521 to move towards each other for resetting.

[0044] The telescopic component in this embodiment includes a telescopic rod 534 with one end connected to the mounting plate 510. The other end of the telescopic rod 534 is connected to the moving plate 531. A top spring 535 is sleeved outside the telescopic rod 534. The settings of the telescopic rod 534 and the top spring 535 can prompt the moving plate 531 to reset and clamp the bottom of the puncture sleeve.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
