Description
Technical Field
The utility model relates to a medical equipment technical field especially relates to a can fix vascular puncture sheath pipe of inner catheter.
Background
At present, artery and vein catheter thrombolysis treatment is widely applied to lower limb ischemic diseases including atherosclerosis, diabetes, arterial occlusion caused by arteritis and lower limb deep vein thrombosis, and is also applied to clinical treatment of superior mesenteric vein embolism, renal artery thromboembolism and the like.
The long catheter is placed in the artery puncture sheath to reach the thrombus position, the tail end of the catheter is connected with a micro pump to continuously pump thrombolytic drugs, and the puncture position is conventionally pressurized and bandaged after the patient returns to the room after the operation, so that the patient is required to lie on the side or on the side. Keeping the limb at the side of the catheter extending to the end of the treatment, and preventing the catheter from moving and falling out caused by the movement of the operative limb.
Thrombolysis catheters are important to ensure the therapeutic effect, and if the catheter is displaced and falls out, the therapy is interrupted.
At present, a fixing mode aiming at the inner catheter is not provided, a sheath catheter and the inner catheter are designed in the long-term practice of medical workers, and the problem of inner catheter slippage in the treatment process can be avoided.
Disclosure of Invention
The utility model aims at solving the defects existing in the prior art and providing a blood vessel puncture sheath tube capable of fixing an inner catheter.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a blood vessel puncture sheath capable of fixing an inner catheter comprises a clamping edge and the inner catheter, wherein the clamping edge is arranged on the inner wall of the sheath, one end of the clamping edge is fixedly connected with the inner wall of the sheath, and the other end of the clamping edge inclines towards the inside of the sheath and forms an acute angle with the inner wall of the sheath; the tail end of the inner conduit is a serrated clamping groove type conduit, and the shape of the clamping groove section is matched with the clamping edge.
Furthermore, the clamping edge is connected with the inner wall of the sheath tube in an integrated manner.
Further, the clamping edge is also provided with a contraction valve.
Furthermore, the corners of the clamping edges are rounded.
Furthermore, a pair of clamping edges are respectively arranged on the corresponding positions of the inner wall of the sheath tube.
Further, the length of the clamping groove section is matched with that of the sheath tube.
Compared with the prior art, the beneficial effects of the utility model are that:
the shape and direction of the clamping groove are matched with the clamping edge, so that no resistance is generated when the catheter is inserted, but when the catheter is stressed in other directions, the clamping edge embedded into the clamping groove can support the catheter to fix the catheter, and the catheter cannot easily slip.
The utility model discloses a use method:
insert the sheath pipe with interior pipe, because the direction of draw-in groove, at the pipe insertion in-process, the card limit can not produce the resistance to the pipe, and the back that finishes, the card limit laminating blocks the pipe both sides in the draw-in groove, makes the pipe not the slippage under the effect of external force, when extracting the pipe, pulls down the shrink valve of sheath pipe both sides, can take out the card limit of both sides from the draw-in groove, and the pipe just can directly be taken out from the sheath pipe.
Drawings

fig. 2 is a schematic view of the catheter removal of the present invention.
Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
A blood vessel puncture sheath capable of fixing an inner catheter is shown in figure 1 and comprises a clamping edge 1 and an inner catheter 2, wherein the clamping edge 1 is arranged on the inner wall of the sheath, one end of the clamping edge 1 is fixedly connected with the inner wall of the sheath, and the other end of the clamping edge 1 inclines towards the inside of the sheath and forms an acute angle with the inner wall of the sheath; the end of inner catheter 2 is the draw-in groove type pipe of cockscomb structure, and the draw-in groove shape and the 1 phase-match in card limit of draw-in groove section 21, card limit 1 still has shrink valve 11, shrink valve 11 with 1 body coupling in card limit, card limit 1 pierces through the sheath pipe inner wall and extends to the sheath outside.
Furthermore, the clamping edge 1 is connected with the inner wall of the sheath tube in an integrated manner.
Furthermore, the corners of the clamping edge 1 are rounded.
Furthermore, a pair of clamping edges 1 are respectively arranged on the corresponding positions of the inner wall of the sheath tube.
Further, the length of the slot section 21 is matched with the sheath.
The utility model discloses a use method: the inner catheter is inserted into the sheath, and because of the direction of the clamping groove in the clamping groove section 21, the clamping edge 1 can not generate resistance to the catheter 2 in the catheter insertion process, and after the completion, the clamping edge 1 is attached in the clamping groove to clamp two sides of the catheter, so that the catheter can not slip off under the action of external force;
as shown in fig. 2, when the catheter 2 is pulled out, the contracting valves 11 on both sides of the sheath tube are pulled downwards, so that the clamping edges 1 on both sides can be pulled out from the clamping grooves, and the catheter 2 can be directly pulled out from the sheath tube.
The present invention has been described in relation to the above embodiments, which are only examples for implementing the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. On the contrary, all changes and modifications which do not depart from the spirit and scope of the present invention are deemed to fall within the scope of the present invention.
