Background
Since the beginning of the seventies of the last century, percutaneous coronary intervention has been widely and rapidly developed worldwide for diagnosis and treatment of atherosclerotic heart disease. Although China starts to start late, the technology is rapidly popularized and is increasingly applied to clinical diagnosis and treatment of heart diseases. According to the latest statistical data, the number of percutaneous coronary intervention treatments in China keeps an annual average growth rate of 20-30% in the last decade.
Although coronary intervention techniques continue to be developed with hopes for numerous patients with coronary heart disease, complications still occur, a significant portion of which are associated with guidewire manipulation. When the coronary intervention diagnosis and treatment is performed, the guide wire penetrates out of the Y-shaped connector, and then an operator needs to push the guide wire and move the guide wire to a working position. When a plurality of guide wires are used for surgery at the same time, the problem that one guide wire is pushed to drive the other guide wire to move easily occurs, so that an operator is difficult to feed the plurality of guide wires into a specified lesion position at the same time, complications such as vessel perforation, tearing, interlayer and the like can be caused, and finally, the surgery is unsuccessful, so that a patient is injured or even killed.
The existing coronary intervention instrument cannot ensure that tools such as guide wires and the like are stably kept at the original position, and cannot ensure that one guide wire is immobile when the other guide wire moves under the condition that a plurality of guide wires enter simultaneously. At present, in the coronary intervention diagnosis and treatment operation process, the stability of the guide wires depends on experience and technology of operators to a certain extent, but the operators with more abundant experience and technology still cannot ensure that other guide wires can move while keeping a plurality of guide wires in the original positions in the instrument exchange process, so that the operation process is influenced.

Examples
Referring to fig. 1-3, the application provides a cap for locking a guide wire, which comprises a cap body 2 covering a Y-shaped connector 1, wherein the cap body 2 is in threaded fit with the Y-shaped connector 1. Offer the locking hole 211 that is used for supplying seal wire 11 to pass on the terminal surface of block body 2, be connected with flexible buckle 23 on the block body 2, the one end integrated into one piece that block body 2 was kept away from to buckle 23 has latch segment 231, latch segment 231 and locking hole 211 gomphosis to chucking seal wire 11.
When the cap is used, the cap is covered on the Y-shaped connector 1, and the guide wire 11 penetrates out of the Y-shaped connector 1 and then penetrates out of the locking hole 211. The locking block 231 is snapped into the locking aperture 211 to clamp the guidewire 11 as desired. The guide wire 11 needing to be kept in the original position can be clamped tightly by the cap, the guide wire 11 needing to be moved can be moved normally, and the guide wire 11 is guaranteed not to be interfered with each other when being moved, so that the smooth operation is guaranteed.
The cap body 2 is further provided with a through hole 21 through which the guide wire 11 can pass, and a channel 212 through which the guide wire 11 can pass is arranged between the through hole 21 and the locking hole 211. Can wear out two seal wires 11 from same Y type connector 1, two seal wires 11 all wear out from through-hole 21, to the seal wire 11 that needs to be fixed, can stir it through passageway 212, get into in the locking hole 211, recycle latch segment 231 and locking hole 211 cooperation, will need fixed seal wire 11 to press from both sides tightly, and the seal wire 11 that needs to remove can normally move in through-hole 21. After the through hole 21 is additionally arranged, the two guide wires 11 can simultaneously penetrate out of one Y-shaped connector 1, and the two guide wires 11 are prevented from interfering with each other when moving, namely, the use cost of locking the guide wires 11 by using the cap is reduced.
The number of the locking holes 211 and the locking blocks 231 is at least one, and each locking hole 211 corresponds to one locking block 231. By providing a plurality of locking holes 211 and locking blocks 231, a plurality of wires 11 can be passed through the Y-connector 1 at the same time. The guide wire 11 penetrates through the through hole 21, the guide wire 11 to be fixed is shifted into one locking hole 211, the corresponding guide wire 11 can be clamped by utilizing the corresponding locking block 231 to be embedded with the locking hole 211, and due to the fact that the locking holes 211 are formed in the scheme, the plurality of guide wires 11 can be simultaneously clamped by utilizing the locking holes 211, namely the cover cap can simultaneously clamp the plurality of guide wires 11, and the application range of the cover cap is expanded.
The breach 22 has been seted up at the border of block body 2, and when installing block body 2, if there is the error in the size of block body 2, when establishing block body 2 cover on Y type connector 1, the deformation of small amplitude can take place for block body 2 to guarantee that block body 2 can cover smoothly and establish on Y type connector 1.
The border shaping that latch segment 231 is close to buckle 23 has annular boss 232, inserts the latch segment 231 after the locking hole 211, boss 232 supports tightly with the surface of block body 2 for buckle 23 can't support tightly with the surface of block body 2, when the art person need extract latch segment 231, can conveniently insert the finger between shifting block and the block body 2, and to 23 application of force of buckle, extract latch segment 231.
Each buckle 23 is provided with two notches 233 for the guide wire 11 to penetrate through, the notches 233 penetrate through the boss 232, the inner sides of the notches 233 are tangent to the side surfaces of the locking block 231, and the two notches 233 are respectively located on two sides of the locking block 231. When the guide wire 11 placed in the locking hole 211 is clamped by the locking hole 211 and the locking block 231, the guide wire 11 extends along the axial direction of the locking hole 211 and can smoothly pass through the notch 233 without being bent by the buckle 23, so that the possibility that the guide wire 11 is bent and damaged is reduced.
The buckle 23 is equipped with bending groove 24 near the one end of block body 2, and when buckle 23 was buckled, bending groove 24 department stress concentration easily deformed to make things convenient for the art person to buckle 23, in order to imbed latch segment 231 in the locking hole 211.
Referring to fig. 1 and 3, the present application also provides a guidewire locker comprising a Y-connector 1 and a cap body 2. A guide wire locker can be formed by matching the cap body 2 with the Y-shaped connector 1.
A wire guide hole 12 for a guide wire 11 to pass through is formed in the Y-shaped connector 1, and an arc chamfer 121 is formed in the edge of the side wall of the wire guide hole 12 facing the cap body 2. When the guide wire 11 is pulled into the through hole 21 or the locking hole 211 after passing out of the guide wire hole 12, the guide wire will contact with the edge of the guide wire hole 12 facing the cap body 2 and generate friction, and the arc chamfer 121 is arranged, so that the possibility that the edge of the guide wire hole 12 abrades the guide wire 11 can be reduced.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the invention as herein taught may be within the scope of the present invention.
