Description

Technical Field

[0001] The utility model relates to the technical field of neurointervention surgery accessories, and in particular to a neurointervention surgery microcatheter fixing device. Background Art

[0002] Neurointerventional surgery is mainly used to treat neurological diseases. It is performed with the support of a digital subtraction angiography (DSA) system, using intravascular catheter operation technology, through specific methods such as selective angiography, dilation shaping, mechanical clearance, and drug delivery. The catheter used is called a microcatheter, which is a reinforced catheter with a very small diameter and no strict size definition. When used, it is introduced into the patient's vascular system and then passed through the patient's blood vessels until the distal end of the microcatheter reaches the desired target position.

[0003] Currently, the catheter is fixed by a catheter fixing belt. The catheter fixing belt on the market is composed of an elastic tie and a catheter fixing patch. The elastic tie is fixed to the patient's abdomen, and the catheter is fixed by Velcro after entering the appropriate position in the patient's artery. When the position of the catheter needs to be adjusted during the operation, the position of the catheter is adjusted by operating the Velcro. Since the Velcro is very sticky, it is easy to pull the patient's surface skin during the adjustment process, causing bleeding, which in turn affects the progress of the interventional procedure.

[0004] In summary, there is an urgent need for a safer neurointerventional microcatheter fixation device to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art in that the patient's surface skin is easily pulled and bleeding occurs during the adjustment process, the utility model provides a microcatheter fixation device for neurointervention with higher safety.

[0006] A neurointerventional microcatheter fixation device includes an arc plate, a telescopic belt, a rotating plate, a lower fixed plate, an upper fixed plate, a first clamping plate, a fixing rod, a rubber pad, a fitting plate and a second clamping plate, which are mounting carriers for parts; the telescopic belt is detachably arranged between the two sides of the arc plate; the anti-slip pad is fixedly connected to the lower side surface of the arc plate; the rotating plate is rotatably connected to the arc plate; the lower fixed plate is fixedly connected to the rotating plate; the upper fixed plate is rotatably connected to the lower fixed plate, and the facing surfaces of the lower fixed plate and the upper fixed plate are both provided with arc grooves; the fixing rod is fixedly connected to the right side of the lower fixed plate; the first clamping plate is rotatably connected to the fixing rod; the rubber pad is fixedly connected to the left side of the first clamping plate; the fitting plate is symmetrically connected to the rotating plate, and the fitting plate is located on the lower side of the lower fixed plate; the second clamping plate, the number of the second clamping plates is set to two, is slidably connected to the arc plate, and the two second clamping plates are in contact with the fitting plate.

[0007] In one embodiment, an anti-slip pad is further included, which is fixedly connected to the lower side of the curved plate.

[0008] In one embodiment, it also includes a fixed block, which is symmetrically fixed to the lower side of the lower fixed plate in a front-to-back manner; a threaded rod, which is threadedly provided on the fixed block; and an extension plate, which is fixedly connected to the threaded rod, and the facing surfaces of the two extension plates are in contact with the lower fixed plate, and an arc groove is opened on the extension plate.

[0009] In one embodiment, the two second clamping plates are oppositely oriented and symmetrically slidably disposed on the arc-shaped plate.

[0010] In one embodiment, the second clamping plate is J-shaped, and the inner circle width of the second clamping plate at the hook is equal to the width of the fitting plate.

[0011] In one embodiment, the lower side of the anti-slip pad is configured to be arc-shaped.

[0012] The beneficial effects of the utility model are:

[0013] The utility model fixes the device and prevents displacement through the cooperation between the arc plate, the telescopic belt and the anti-slip pad. The upper fixing plate is rotated to open, and the arc groove places and guides the catheter. The upper fixing plate is rotated in the opposite direction to contact and fix the catheter with the lower fixing plate. In this way, pulling the patient's surface skin, causing bleeding and thus affecting the operation, can be avoided, and the safety is higher. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0022] Example: A microcatheter fixation device for neurointervention, such as Figures 1-6 As shown, it includes an arc plate 1, a telescopic belt 2, a rotating plate 4, a lower fixed plate 5, an upper fixed plate 6, a first clamping plate 8, a fixing rod 9, a rubber pad 10, a fitting plate 13 and a second clamping plate 14. The arc plate 1 is a mounting carrier for parts. A telescopic belt 2 is detachably provided between the two sides of the arc plate 1. The lower side of the arc plate 1 is fixedly connected with an anti-slip pad 3. The arc plate 1 is rotatably connected with a rotating plate 4. The rotating plate 4 is fixedly connected with a lower fixed plate 5. The lower fixed plate 5 is rotatably connected with an upper fixed plate 6. The facing surfaces of the lower fixed plate 5 and the upper fixed plate 6 are both provided with an arc groove 15. The right side of the lower fixed plate 5 is fixedly connected with a fixing rod 9. The fixing rod 9 is rotatably connected with the first clamping plate 8. A rubber pad 10 is fixedly connected to the left side of the first clamping plate 8, and the rotating plate 4 is symmetrically connected to the fitting plate 13. The fitting plate 13 is located on the lower side of the lower fixed plate 5. The second clamping plate 14 is symmetrically slidably connected to the curved plate 1. The two second clamping plates 14 are arranged in opposite directions. The second clamping plate 14 is J-shaped. The inner circle width of the second clamping plate 14 barb is equal to the width of the fitting plate 13. By rotating the first clamping plate 8, the rubber pad 10 is disengaged from the fixing rod 9, and the upper fixing plate 6 is disengaged from the lower fixing plate 5. The catheter is placed in the arc groove 15. The arc groove 15 guides the catheter. The upper fixing plate 6 and the first clamping plate 8 are rotated in opposite directions in turn to fix the catheter.

[0023] like Figure 2 As shown, an anti-skid pad 3 is also included. The lower side of the arc-shaped plate 1 is fixedly connected to the anti-skid pad 3, and the lower side of the anti-skid pad 3 is set to an arc shape.

[0024] like Figure 5 As shown, it also includes a threaded rod 11, a fixed block 12 and an extension plate 16. The lower side surface of the lower fixed plate 5 is fixedly connected to the fixed block 12 in a front-to-back symmetrical manner. The fixed block 12 is threaded with a threaded rod 11, and the threaded rod 11 is fixedly connected to the extension plate 16. The extension plate 16 has an arc groove 15. The facing surfaces of the two extension plates 16 are in contact with the lower fixed plate 5. The threaded rod 11 and the fixed block 12 cooperate to make the extension plate 16 contact with the lower fixed plate 5, thereby increasing the placement surface of the catheter.

[0025] When the device needs to be used, the patient lies down on the operating table, and the staff removes one end of the retractable belt 2 from the curved plate 1, goes around the surgical site of the patient's body and reconnects it to one side of the curved plate 1 so that it is fixed near the surgical site of the patient. The anti-slip pad 3 contacts the patient's skin to prevent the device from shifting. According to the position of blood vessel puncture, the lower fixing plate 5 is rotated, and the lower fixing plate 5 drives the rotating plate 4, the upper fixing plate 6, the first clamping plate 8, the fixing rod 9, the rubber pad 10 and the fitting plate 13 to rotate to a suitable angle, and then, the second clamping plate 14 is moved toward each other to contact the fitting plate 13, and the fitting plate 13 contacts and fixes it with the second clamping plate 14, thereby fixing the angle of the lower fixing plate 5 and the upper fixing plate 6, and then, the first clamping plate 8 is rotated to drive the rubber pad 10 to rotate and disengage from the fixing rod 9, and the upper fixing plate 6 is rotated to disengage from the lower fixing plate 5, and the largest catheter is shifted along the guide wire into the blood vessel. , the staff places the part of the catheter exposed outside the patient's body in the arc groove 15, and the arc groove 15 can place and guide the catheter, and reversely rotate the upper fixing plate 6 to contact the lower fixing plate 5 again, and reversely rotate the first clamping plate 8 to drive the rubber pad 10 to contact the fixing rod 9 again, so that the upper fixing plate 6 and the catheter are fixed again. When the position of the catheter needs to be adjusted during the interventional procedure, open the upper fixing plate 6 according to the above operations, close the upper fixing plate 6 to fix the catheter and continue the operation. The above operations can avoid pulling the patient's surface skin, causing bleeding to affect the operation, and are safer. After the interventional surgery is completed, open the upper fixing plate 6 again according to the above operations, and remove the catheter from the patient's blood vessel and the arc groove 15 in turn. Finally, close the upper fixing plate 6, pull out one end of the telescopic belt 2 from the side of the arc plate 1, and remove the device from the patient.

[0026] Since the catheter is made of soft material with good elasticity and flexibility, before adjusting the position of the catheter, it is necessary to first extend the placement surface to avoid the catheter from operating in a bent state and to guide the catheter. Therefore, move the extension plate 16, align the threaded rod 11 with a threaded hole on the fixed block 12, rotate the extension plate 16 to drive the threaded rod 11 into the fixed block 12, and the extension plate 16 contacts the side of the lower fixed plate 5, extending the placement surface to guide the catheter.

[0027] The above description is merely an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent substitutions made within the principles of the present invention shall be included within the scope of protection of the present invention. Any matters not fully described in the present invention are prior art known to those skilled in the art.
