股动脉穿刺点封堵止血器Femoral artery puncture point occlusion hemostat

技术领域technical field

本发明涉及医疗止血器械,尤其涉及股动脉穿刺点封堵止血器。The invention relates to a medical hemostasis device, in particular to a hemostatic device for puncturing a femoral artery puncture point.

背景技术Background technique

经股动脉穿刺介入疗法中，股动脉穿刺点的止血方法通常采用人工压迫止血，需要医护人员用手或器械压迫穿刺部位10-15分钟。人工压迫止血为传统止血方式，医护人员经验较为丰富。但是人力耗费较大。为解决上述技术问题，本领域技术人员设置封堵止血器，通过封堵止血器将可吸收插塞释放于血管切开点上方和腱膜下方，可吸收插塞吸血膨胀，从而堵止血。但是可吸收插塞在膨胀时，当期横向膨胀可能会导致扩张血管切开点，导致血管切开点无法闭合，从而导致止血失败。In transfemoral artery puncture interventional therapy, the hemostasis method of the femoral artery puncture point is usually artificial compression to stop bleeding, which requires medical staff to press the puncture site with hands or instruments for 10-15 minutes. Artificial compression hemostasis is a traditional method of hemostasis, and medical staff are more experienced. But manpower consumption is high. In order to solve the above technical problems, those skilled in the art set up a blocking hemostat, and the absorbable plug is released above the vascular incision point and below the aponeurosis through the blocking hemostatic device, and the absorbable plug absorbs blood and expands, thereby blocking the hemostasis. However, when the absorbable plug is inflated, the current lateral expansion may lead to dilation of the incision point of the blood vessel, resulting in the inability to close the incision point of the blood vessel, resulting in the failure of hemostasis.

本发明提供的股动脉穿刺点封堵止血器，通过设置记忆合金网，将可吸收插塞的远端进行限定，使其吸血后延长度方向膨胀，从而实现增加向下挤压血管力度，提高止血能力。同时避免横向膨胀中，若吸收插塞过于贴近血管切口，导致血管切口闭合不完全，从而发生腹股沟血肿和动脉假性动脉瘤等问题。The femoral artery puncture point blocking hemostatic device provided by the invention, by setting the memory alloy mesh, the distal end of the absorbable plug is limited, so that the extension direction expands after blood sucking, so as to increase the downward pressure on the blood vessel and improve the Hemostatic ability. At the same time, avoid lateral expansion, if the absorption plug is too close to the vascular incision, resulting in incomplete closure of the vascular incision, resulting in inguinal hematoma and arterial pseudoaneurysm and other problems.

具体实施方式Detailed ways

下面将结合本发明的实施例，对本发明的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The technical solutions of the present invention will be clearly and completely described below with reference to 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 shall fall within the protection scope of the present invention.

根据图1-5所示，作为实施例，股动脉穿刺点封堵止血器，采用医用高分子材料制作，如聚氨酯或聚丙烯等材料。主要包括扩张管 1、鞘管2、推进器4、定位器5等零部件及可吸收插塞。扩张管及鞘管2为现有技术。扩张管1的内径与定位器5的外径紧密配合。定位器5定位在血管切口后，将鞘管2套在扩张管1上顺着定位器5插入肌肉穿刺通道至血管外壁。As shown in Figures 1-5, as an embodiment, the femoral artery puncture point blocking hemostatic device is made of medical polymer materials, such as polyurethane or polypropylene. It mainly includes parts such as dilation tube 1,sheath tube 2, propeller 4,positioner 5 and absorbable plugs. The dilation tube and thesheath tube 2 are in the prior art. The inner diameter of the expansion tube 1 closely matches the outer diameter of thepositioner 5 . After thepositioner 5 is positioned in the blood vessel incision, thesheath tube 2 is sheathed on the dilation tube 1 and inserted into the muscle puncture channel along thepositioner 5 to the outer wall of the blood vessel.

鞘管2包括薄壁管201和把手202，薄壁管201与把手202通过粘合等方式相连接。Thesheath tube 2 includes a thin-walled tube 201 and ahandle 202, and the thin-walled tube 201 and thehandle 202 are connected by means of bonding or the like.

推进器设置推进管401、推送杆402、推送柄403等，推送管401 与推送杆402通过卡口连接，推送杆402可沿推送管401向前推动。推送杆402与推送柄403连接。可吸收插塞3存储在推送管401内部，当鞘管2定位后，推进器将可吸收插塞3沿鞘管2的把手202内腔推送至血管切开点上方、腱膜下方处。可吸收插塞选用可吸收降解的生物材料，如合成聚乙醇酸，吸血后具有良好的膨胀性能，进而压迫止血。合成聚乙醇酸为现有材料，再此不做赘述。在可吸收插塞3外套设记忆合金网311，记忆合金网采用镍钛合金管通过激光镂空雕刻而成。记忆合金网311的高度小于所述可吸收插塞3的高度。记忆合金网311的远端与可吸收插塞3的远端持平，当可吸收插塞3吸血时膨胀，记忆合金网311限制可吸收插塞3横向膨胀，使其倾向于纵向膨胀。从而压迫血管穿刺点，进而达到止血效果。同时避免可吸收插塞 3远端贴合血管穿刺点处位置，在横向膨胀时，带动血管穿刺点横向扩展，导致无法迅速闭合的问题。记忆合金网311的远端设置压翼 312，所述压翼312与所述记忆合金网311的夹角α为89°，角度过大易发生刺破血管的风险。压翼312表面设置胶原蛋白海绵层，在吸血时进行膨胀，从而压迫血管穿刺点周边血管壁，使血管穿刺点闭合更加紧密，从而进一步加快止血。可吸收插塞的近端设置环形合成聚乙醇酸加强筋313。增大膨胀量，提高更大的压力。The pusher is provided with apush pipe 401 , apush rod 402 , apush handle 403 , etc. Thepush pipe 401 and thepush rod 402 are connected by a bayonet, and thepush rod 402 can be pushed forward along thepush pipe 401 . Thepush rod 402 is connected to thepush handle 403 . Theabsorbable plug 3 is stored inside thepush tube 401. After thesheath tube 2 is positioned, the pusher pushes theabsorbable plug 3 along the lumen of thehandle 202 of thesheath tube 2 to above the vascular incision point and below the aponeurosis. The absorbable plug is made of biomaterials that can be absorbed and degraded, such as synthetic polyglycolic acid, which has good expansion performance after blood sucking, thereby compressing to stop bleeding. Synthetic polyglycolic acid is an existing material, and will not be repeated here. Amemory alloy mesh 311 is arranged on the outer cover of theabsorbable plug 3, and the memory alloy mesh is carved from a nickel-titanium alloy tube through laser hollowing. The height of thememory alloy mesh 311 is smaller than the height of theabsorbable plug 3 . The distal end of thememory alloy mesh 311 is flush with the distal end of theabsorbable plug 3, and when theabsorbable plug 3 sucks blood, it expands. Thereby compressing the puncture point of the blood vessel, thereby achieving the effect of hemostasis. At the same time, it is avoided that the distal end of theabsorbable plug 3 fits the position of the vascular puncture point, and when it expands laterally, it drives the vascular puncture point to expand laterally, resulting in the problem that it cannot be quickly closed. The distal end of thememory alloy mesh 311 is provided with apressure wing 312, and the included angle α between thepressure wing 312 and thememory alloy mesh 311 is 89°, and if the angle is too large, the risk of puncturing the blood vessel may occur. The surface of thepressure wing 312 is provided with a collagen sponge layer, which expands when sucking blood, thereby compressing the blood vessel wall around the blood vessel puncture point, and closing the blood vessel puncture point more tightly, thereby further accelerating hemostasis. An annular synthetic polyglycolicacid reinforcing rib 313 is provided at the proximal end of the absorbable plug. Increase the amount of expansion and increase the greater pressure.
