The embodiment of the application discloses a transplantation catheter convenient to assemble.
The first embodiment is as follows:
referring to fig. 1 and 2, an easily assembled graft catheter includes an outer tube 1 and an inner tube 2 which are used in cooperation with each other, the outer tube 1 having an inner diameter larger than an outer diameter of the inner tube 2, and the inner tube 2 inserted into the outer tube 1 along a length direction of the outer tube 1 for use.
Referring to fig. 1 and 2, the outer tube 1 includes a socket tube section 11 and an introduction tube section 12 in order along the insertion direction of the inner tube 2. The side wall of the socket pipe section 11 is provided with a notch 3, the top of the notch 3 is communicated with the top of the socket pipe section 11, and the size of the opening angle of the end part of the outer pipe 1 is enlarged. The gap 3 is a rectangular gap 3 with a height larger than the inner diameter of the outer tube 1, and the width of the gap 3 is the diameter of the outer tube 1, so that the opening area of the end part of the outer tube 1 is enlarged. In assembling the graft catheter, the inner tube 2 may be inserted into the outer tube 1 at a large notch 3 and at various angles, thereby facilitating the assembly and use of the graft catheter by the operator.
Referring to fig. 1 and 2, a first stop 5 is integrally formed on the side wall of the socket pipe section 11 to close the gap 3. First dog 5 is rectangle bent plate and lock in breach 3 department, and 5 bottoms of first dog are connected with 3 bottoms of breach, and 5 lateral walls of first dog are closely laminated with 3 borders in breach. Because the outer tube 1 is made of soft material and has certain elastic deformation, the top end of the first stop block 5 can be lifted, and the inner tube 2 is inserted from the notch 3. The cover is equipped with the lantern ring 6 on 11 outer walls of socket pipeline section, and lantern ring 6 is the rubber ring, 6 inner walls of lantern ring and 11 outer wall interference fit of socket pipeline section. After the inner pipe 2 is inserted, the first stop block 5 is buckled to seal the notch 3, and the lantern ring 6 is slid and moved onto the first stop block 5, so that the first stop block 5 is tightly buckled at the notch 3 of the socket pipe section 11, and the situation that the inner pipe 2 slides out of the outer pipe 1 from the notch 3 is reduced.
Referring to fig. 1, in order to reduce the occurrence of arch blockage of the inner pipe 2, the joint of the spigot pipe section 11 and the lead-in pipe section 12 of the outer pipe 1 is curved, and the insertion end of the inner pipe 2 is provided with a chamfer 4. After the inner tube 2 is inserted into the socket tube 11, the inner tube 2 is inserted into the introduction tube 12 along the curved connection, and the guide angle 4 at the end of the inner tube 2 is matched, so that the inner tube 2 is smoothly slid into the outer tube 1, and the assembly of the transplantation catheter is completed.
The implementation principle of a transplantation catheter convenient to assemble in the first embodiment of the application is as follows: lift 5 tops of first dog, place the end of inserting of inner tube 2 in breach 3 departments, because breach 3 has enlarged the open area and the open angle of 1 tip of outer tube, thereby be convenient for inner tube 2 to insert outer tube 1, afterwards, promote inner tube 2, the smooth immigration of junction along the bending of 2 tip of inner tube is 1 in, thereby reduce the phenomenon emergence that the soft inner tube 2 of material becomes to encircle the jam, be convenient for the operator inserts inner tube 2 in the outer tube 1, accomplish the equipment of transplanting the pipe, insert the back, closed first dog 5, use.
Example two:
referring to fig. 3 and 4, the difference from the first embodiment is that the notch 3 is located in the middle of the side wall of the socket pipe section 11, and the width of the notch 3 is smaller than the inner diameter of the outer pipe 1. A second stop block 7 is integrally formed on the side wall of the socket pipe section 11, the second stop block 7 is a rectangular bent plate and is buckled at the notch 3, one end, far away from the leading-in pipe section 12, of the second stop block 7 is connected with the top of the notch 3, and the side wall of the second stop block 7 is tightly attached to the edge of the notch 3. The insertion end of the inner tube 2 is abutted against the top surface of the second stopper 7, the bottom end of the second stopper 7 is pressed into the socket tube section 11, an insertion gap is formed between the second stopper 7 and the side wall of the socket tube section 11, and the inner tube 2 is directly and quickly inserted into the outer tube 1 from the insertion gap under the guiding action between the notch 3 and the second stopper 7, so that the assembly of the transplantation catheter is facilitated.
Referring to fig. 4, a compression spring 8 is arranged in the socket pipe section 11, the compression spring 8 is located at the bottom end of the second stopper 7, and two ends of the second spring are respectively fixedly connected with the second stopper 7 and the inner side wall of the socket pipe section 11. The second stopper 7 is in a state of closing the notch 3 in a free state of the compression spring 8. When the second stop dog 7 is pressed down, the compression spring 8 deforms, and the compression spring 8 automatically rebounds after the inner tube 2 is completely inserted into the outer tube 1, so that the second stop dog 7 restores to the original position and closes the notch 3.
In the second embodiment of the present application, an implementation principle of a conveniently assembled transplantation catheter is as follows: push down 7 bottoms of second dog, insert the insertion clearance that forms between 7 bottoms of second dog and the 11 lateral walls of socket pipeline section with inner tube 2, and under the guide effect of breach 3 and second dog 7, be convenient for with inner tube 2 direct, quick the inserting in outer tube 1, thereby the operator of being convenient for assembles the transplantation pipe, at this moment, compression spring 8 takes place deformation, and at inner tube 2 automatic resilience after inserting outer tube 1 completely, drive 7 automatic re-setting of second dog and seal breach 3.
The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
