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

[0002] Intravascular interventional technology is a newly developed method for preventing and treating cerebrovascular disease, which has certain advantages over traditional cerebrovascular disease treatment methods.

[0003] During interventional treatment, the puncture needle needs to be fixed. When the positioning device in the prior art is used for fixing, the puncture sleeve needs to be fixed, and the automatic centering effect is not very ideal, and the operation is also relatively troublesome. Summary of the invention

[0004] The present invention provides a neurological cerebrovascular interventional puncture positioning device, 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 neurological cerebrovascular interventional puncture positioning device, comprising 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 a puncture sleeve is provided on the upper part of the adjustment mechanism; the clamping and positioning mechanism comprises a mounting plate connected to the adjustment mechanism, two groups of side clamping assemblies arranged on the mounting plate, and an intermediate top connection assembly arranged between the two groups of side clamping assemblies, and the two groups of side clamping assemblies are connected to the intermediate top connection assembly through a linkage assembly.

[0006] By adopting the above technical solution: the base is installed on the operating bed or the hospital bed, and is used to install the entire positioning device. The position of the adjustment mechanism installed by the sliding mechanism can be relatively changed to adapt to the puncture position. By setting the clamping and positioning mechanism, when installing the puncture sleeve, the puncture sleeve can be adaptively positioned and fixed by pressing down the puncture sleeve. During the fixing process, pressing down the puncture sleeve can make the two side clamping components and the middle top connection component expand outward at the same time to form a clamping cavity. When the puncture sleeve enters the clamping cavity, the two sets of side clamping components and the middle top connection component are reset, and the puncture sleeve is automatically centered, clamped and fixed.

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

[0008] By adopting the above technical solution: the setting of the arc T-shaped slide groove can position the patient's head for puncture on a semicircle, the setting of the adjustment structure can adjust the angle of the device to facilitate adaptation to the puncture position, and by setting a locking component, the position of the adjustment column can be relatively locked after the position of the adjustment column is adjusted into place, thereby facilitating the auxiliary positioning of the puncture sleeve.

[0009] Optionally, the locking assembly includes a locking plate arranged at the lower part of the adjusting column, the locking plate is provided with a threaded hole, and a locking screw is threadedly connected in the threaded hole.

[0010] By adopting the above technical solution: after the position of the adjusting column is adjusted to the right position, 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, and an adjusting screw is provided between the upper rod and the lower rod.

[0012] By adopting the above technical solution, the upper rod can be rotated relative to the lower rod, so that the swing direction of the upper rod can be changed, so that the puncture position can be adapted in multiple directions, and can be locked by adjusting the screw after the adjustment is completed.

[0013] Optionally, the side clamping assembly includes two opposite clamping plates slidably arranged on the mounting plate via an elastic assembly, and a guide clamping block is provided on the upper portion of the clamping plate.

[0014] By adopting the above technical solution: when installing the puncture sleeve, by pressing down the puncture sleeve, the puncture sleeve contacts and pushes the guide clamping blocks to move away from each other, thereby driving the two mounting plates to compress the elastic components to move away from each other, and the two mounting plates drive the middle top connection component to move downward through the linkage component to gradually form a clamping cavity. When the puncture sleeve completely slides through the two guide clamping blocks, the two mounting plates approach each other, and the middle top connection component is also reset to clamp the puncture sleeve.

[0015] Optionally, the intermediate top connection assembly includes a movable plate arranged on the mounting plate through a telescopic assembly, a top connection column is provided on the upper portion of the movable plate, and an arc-shaped holding plate for clamping the puncture sleeve is provided on the top connection column.

[0016] By adopting the above technical solution: driven by the linkage component, when the two mounting plates move back to back, the linkage component can drive the movable plate to move downward, and at the same time compress the telescopic component. When resetting, the two arc-shaped holding plates clamp the bottom of the puncture sleeve.

[0017] Optionally, the linkage assembly includes a retaining rod, the lower end of which is fixed to the mounting plate, the other end of which passes through the movable plate, and a crank connecting rod hinged to the upper end of the retaining rod, the lower end of which abuts against the upper surface of the movable plate, the other end of the crank connecting rod is hinged to one end of the 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: the retaining rod can limit the movable plate so that it can only move up and down, and secondly, it is used to install the crank connecting rod. When the two mounting plates move away from each other, the crank connecting rod can swing through the pull rod, so that the crank connecting rod pushes the movable plate downward.

[0019] Optionally, the guide clamping block includes a downwardly inclined sliding slope portion and a clamping portion arranged below the sliding slope portion.

[0020] By adopting the above technical solution: when the puncture sleeve is pressed down, the two guide clamping blocks can be moved away from each other by setting the sliding inclined portion. When the guide clamping blocks are returning to their original positions, the clamping portion can be used to clamp the upper part of the puncture sleeve.

[0021] Optionally, the elastic component includes a fixing plate arranged on the mounting plate, one end of a return spring is fixed on 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 reset spring can push the two clamping plates to move towards each other for reset.

[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 movable plate, and a top spring is sleeved on the outer side of the telescopic rod.

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

[0025] The working principle and beneficial effects of the present invention are: 1. The base of the present invention is installed on an operating bed or a hospital bed to install the entire positioning device. The position of the adjustment mechanism installed by the sliding mechanism can be relatively changed to adapt to the puncture position. By setting a clamping and positioning mechanism, when installing the puncture sleeve, the puncture sleeve can be adaptively positioned and fixed by pressing down the puncture sleeve. During the fixing process, pressing down the puncture sleeve can make the two side clamping components and the middle top connection component expand at the same time to form a clamping cavity. When the puncture sleeve enters the clamping cavity, the two sets of side clamping components and the middle top connection component are reset to achieve automatic centering, clamping and fixing of the puncture sleeve.

[0026] 2. When installing the puncture sleeve, by pressing down the puncture sleeve, the puncture sleeve contacts and pushes the guide 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 middle top connection component to move downward through the linkage component to gradually form a clamping cavity. When the puncture sleeve completely slides through the two guide clamping blocks, the two mounting plates approach each other, and the middle top connection component is also reset to clamp the puncture sleeve.

DETAILED DESCRIPTION

[0030] The following will be combined with 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] like Figure 1-Figure 3As shown, this embodiment provides a neurological cerebrovascular interventional puncture positioning device, including a base 100, which can be injection molded, and an adjustment mechanism 300 is slidably provided on the base 100 through a sliding mechanism 200; the upper part of the adjustment mechanism 300 is provided with a clamping positioning mechanism 500 for adaptively and continuously clamping and fixing the puncture sleeve 400; the clamping positioning mechanism 500 in this embodiment includes a mounting plate 510 connected to the adjustment mechanism 300, two groups of side clamping assemblies 520 arranged on the mounting plate 510, and an intermediate top connection assembly 530 arranged between the two groups of side clamping assemblies 520, and the two groups of the side clamping assemblies 520 are connected to the intermediate top connection assembly 530 through a linkage assembly 540.

[0032] The basic principle of this embodiment is as follows: the base 100 is installed on an operating bed or a hospital bed and is used to install the entire positioning device. The position of the adjustment mechanism 300 installed by the sliding mechanism 200 can be relatively changed to adapt to the puncture position. By setting the clamping and positioning mechanism 500, when installing the puncture sleeve 400, the puncture sleeve 400 can be adaptively positioned and fixed by pressing down the puncture sleeve 400. During the fixing process, pressing down the puncture sleeve 400 can make the two side clamping components 520 and the middle top connection component 530 expand at the same time to form a clamping cavity. When the puncture sleeve 400 enters the clamping cavity, the two groups of side clamping components 520 and the middle top connection component 530 are reset to achieve automatic centering, clamping and fixing of the puncture sleeve 400.

[0033] In order to facilitate the adjustment of the position to adapt to the puncture position, the sliding mechanism 200 in this embodiment includes an arc T-shaped groove arranged on the base 100, and the adjustment mechanism 300 includes an adjustment column 310 whose lower end is slidably arranged inside the arc T-shaped groove. A T-shaped slider is provided at the lower part of the adjustment column 310, and the T-shaped slider is slidably arranged inside the arc T-shaped groove. A locking assembly is provided between the adjustment column 310 and the arc T-shaped groove. The setting of the arc T-shaped groove can position the patient's head for puncture on a semicircle. The setting of the adjustment structure can adjust the angle of the device to facilitate adaptation to the puncture position. By setting the locking assembly, the position of the adjustment column 310 can be relatively locked after the position of the adjustment column 310 is adjusted into place, thereby facilitating the auxiliary positioning of the puncture sleeve 400.

[0034] The locking assembly includes a locking plate 320 arranged at the lower part of the adjustment column 310, and the locking plate 320 is provided with a threaded hole 330. The threaded hole 330 is internally threaded with a locking screw. After the position of the adjustment column 310 is adjusted to the right position, the locking screw is continuously screwed into the threaded hole 330 to fix the adjustment column 310.

[0035] The adjustment column 310 in this embodiment includes a lower rod 340 and an upper rod 350 rotatably connected to the lower rod 340. An adjustment 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 swing direction of the upper rod 350 can be changed, so that it can adapt to the puncture position in multiple directions. After the adjustment is completed, it can be locked by the adjustment screw 360.

[0036] The side clamping assembly 520 includes two opposite clamping plates 521 slidably arranged on the mounting plate 510 through an elastic assembly, and a guide clamping block 522 is provided on the upper portion of the clamping plate 521. When installing the puncture sleeve, the puncture sleeve 400 is pressed down, and the puncture sleeve 400 contacts and pushes the guide clamping block 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 middle top connection assembly 530 to move downward through the linkage assembly 540 to gradually form a clamping cavity. When the puncture sleeve 400 completely slides over the two guide clamping blocks 522, the two mounting plates 510 approach each other, and the middle top connection assembly 530 is also reset to clamp the puncture sleeve 400.

[0037] The middle top-connecting assembly 530 includes a movable plate 531 arranged on the mounting plate 510 through a telescopic assembly, a top-connecting column 532 is provided on the upper part of the movable plate 531, and an arc-shaped holding piece 533 for clamping the puncture sleeve 400 is provided on the top-connecting column 532. When the two mounting plates 510 move away from each other, the movable plate 531 can be driven downward by the linkage assembly 540, and the telescopic assembly can be compressed at the same time. When resetting, the two arc-shaped holding pieces 533 clamp the bottom of the puncture sleeve.

[0038] Specifically, the linkage assembly 540 in this embodiment includes a retaining rod 541, the lower end of which is fixed on the mounting plate 510, and the other end of the retaining rod 541 passes through the movable plate 531. It also includes a crank connecting rod 542 hinged at the upper end of the retaining rod 541, the lower end of the crank connecting rod 542 abuts against the upper surface of the movable plate 531, and the other end of the crank connecting rod 542 is hinged to one end of a pull rod 543, and 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 movable plate 531 so that it can only move up and down, and is 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 swing through the pull rod 543, so that the crank connecting rod 542 pushes the movable plate 531 downward.

[0039] Specifically, the guide clamping block 522 includes a downwardly inclined sliding slope portion 523 and a clamping portion 524 arranged at the lower part of the sliding slope portion 523. When the puncture sleeve is pressed down, the sliding slope portion 523 is arranged to enable the two guide clamping blocks 522 to move away from each other. When the guide clamping block 522 is returning to its original position, the clamping portion 524 can be used to clamp the upper part of the puncture sleeve 400.

[0040] The elastic component of this embodiment includes a fixing plate 525 arranged on the mounting plate 510, and one end of a reset spring 526 is fixed on the fixing plate 525. The other end of the reset spring 526 is connected to the clamping plate 521. The setting of the reset spring 526 can push the two clamping plates 521 to move toward each other for reset.

[0041] The telescopic assembly in this embodiment includes a telescopic rod 534 with one end connected to the mounting plate 510, and the other end of the telescopic rod 534 is connected to the movable plate 531. A top spring 535 is sleeved on the outer side of the telescopic rod 534. The arrangement of the telescopic rod 534 and the top spring 535 can cause the movable plate 531 to reset and clamp the bottom of the puncture sleeve.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
