[0018] See also Figure 1-Figure 7 The present invention provides a coronary intervention guide wire tip shaper, comprising a shaping mold 1, wherein the shaping mold 1 comprises a shaping die head 101, a shaping die head 2 102 and a shaping die head 3 103, wherein the upper surfaces of the shaping die head 101 and the shaping die head 2 102 are fixedly connected with a T-shaped pin 104, and the lower surfaces of the shaping die head 2 102 and the shaping die head 3 103 are provided with a T-shaped groove 105, and the upper surfaces of the shaping die head 101, the shaping die head 2 102 and the shaping die head 3 103 are penetrated with a triangular insertion hole 106; The molding mechanism 2 includes a base 201, the upper surface of the base 201 is fixedly connected with a mold plug-in connector 202, and the upper surface of the base 201 is penetrated with an arc groove 203, the inside of the arc groove 203 is slidably connected with a sliding block 204, the bottom of the sliding block 204 is plugged with a handle 205, and the top of the sliding block 204 is fixedly connected with a short rail 206, the upper surface of the short rail 206 is slidably connected with an L-shaped support plate 207, the upper surface of the L-shaped support plate 207 is fixedly connected with a columnar bending head 208, the upper surface of the short rail 206 is fixedly connected with an ear 209, the internal thread of the ear 209 is connected with a No. 1 adjusting rod 210, and the outer surface of the handle 205 is hooked with a tension spring 211.

[0019] See also Figure 1 , Figure 3 and Figure 6 The mold plug connector 202 includes a rotating shaft and a triangular plug rod. The rotating shaft is fixedly connected to the inside of the base 201, and the top of the rotating shaft is fixedly connected to the triangular plug rod. The triangular plug rod and the triangular insertion hole 106 are adapted to each other. The shaping die head 101, the shaping die head 2 102 and the shaping die head 3 103 are connected to each other through T-shaped pins 104 and T-shaped slots 105. The shaping die head 101, the shaping die head 2 102 and the shaping die head 3 103 are all cylindrical.

[0020] By setting a T-shaped pin 104 and a T-shaped slot 105, the shaping die head 101, the shaping die head 2 102 and the shaping die head 3 103 can be connected together for storage when not in use. When the tip of the guide wire needs to be bent and shaped, a suitable die head is selected from the shaping die head 101, the shaping die head 2 102 and the shaping die head 3 103 as a mold for shaping the tip of the guide wire into a J shape. The cross-sectional diameters of the shaping die head 101, the shaping die head 2 102 and the shaping die head 3 103 are set to 6 mm, 5 mm and 4 mm, so that medical staff can bend the tip of the guide wire according to the coronary intervention procedure. The appropriate die head can be selected according to the demand. For example, when treating lesions at the bifurcation of the left anterior descending branch and the diagonal branch of the coronary artery, the J-bend diameter of the guide wire tip generally needs to reach about 6 mm. At this time, the shaping die head 101 can be selected as the shaping mold for the guide wire tip. For another example, when intervening in a coronary artery with a normal diameter, the J-bend diameter of the guide wire tip needs to be about 4 mm or 5 mm. By setting the shaping mold 1 with three dies of different diameters, a variety of options are provided for the diameter requirements of the guide wire tip bend during coronary artery intervention, thereby improving the applicability of the entire shaper.

[0021] See also Figure 1-Figure 2 , Figure 4-Figure 7 The molding structure 2 also includes a second ear 212, the internal thread of the second ear 212 is connected to a second adjusting rod 213, the front end of the second adjusting rod 213 is rotatably connected to a clamping block 214, the upper surface of the base 201 is provided with a guide groove 215, the bottom end of the clamping block 214 is slidably connected to the guide groove 215, the upper surface of the base 201 and the edge around the arc groove 203 are engraved with angle scale lines, the base 201 includes a layered protrusion 2011 located at the top, the layer The upper surface of the protrusion 2011 is engraved with millimeter scale lines, and an ear block is fixedly connected to the outer surface of the handle 205. The outer surface of the ear block is provided with a fine hole, which is hooked with one end of the tension spring 211, and the other end of the tension spring 211 is hooked with a pin, and the pin is fixedly connected to the lower surface of the base 201. The sliding block 204 includes a square plug rod arranged at the bottom end, and the handle 205 includes a cylindrical joint connected to the square plug rod, and the cylindrical joint and the square plug rod are connected by screws.

[0022] By placing the guide wire to be bent on the layered protrusion 2011, the length of the guide wire tip that needs to be bent can be measured by the millimeter scale lines engraved on the layered protrusion 2011, and then a marker can be used to mark the outer surface of the guide wire. Then, according to the requirement of the J-bend diameter of the guide wire tip, a suitable die head is selected. For example, after the shaping die head 101 is selected, it is separated from the shaping die head 2 102 and the shaping die head 3 103, and then the triangular insertion hole 106 opened on the shaping die head 101 is connected to the mold The plug connector 202 is docked, and the guide wire head end is attached to the outer surface of the shaping wood 101. The No. 2 adjusting rod 213 is rotated to feed it in the second ear 212, so that the No. 2 adjusting rod 213 can drive the pressing block 214 to move, and with the assistance of the guide groove 215, it is ensured that the pressing block 214 can press the outer surface of the guide wire. It is worth noting that the part of the guide wire head end that needs to be bent should not be pressed by the pressing block 214, and then the No. 1 adjusting rod 210 is rotated to feed it in the ear 1 209, so that the No. 1 adjusting rod 210 can be rotated to feed it in the second ear 212. The adjusting rod 210 can drive the L-shaped support plate 207 to slide on the short rail 206, so that the distance between the cylindrical bending head 208 and the shaping die head 101 can be adjusted. Since the length of the guide wire tip end for shaping before the coronary intervention surgery needs to be selected according to the actual situation, this means that the length of the J-shape of the guide wire tip end is different when the guide wire tip end is shaped. By setting the position of the cylindrical bending head 208 to be adjustable, it can be ensured that the cylindrical bending head 208 can contact the guide wire tip end before it is bent and shaped. The outer surface of the wire is then rotated by turning the handle 205 to drive the sliding block 204 to slide in the arc groove 203, so that the cylindrical bending head 208 slides along with the sliding block 204, and the cylindrical bending head 208 cooperates with the shaping die head 101 to bend the guide wire tip end into a J shape, and the roundness of the bending can be determined by referring to the angle scale line. After the shaping of the guide wire tip end is completed, the handle 205 is released, and the handle 205 can be reset under the action of the tension spring 211, thereby driving the cylindrical bending head 208 to reset.

[0023] When using, first, select a suitable shaping die according to the needs of the coronary interventional surgery. For example, when treating lesions at the bifurcation of the left anterior descending branch and the diagonal branch of the coronary artery, the J-bend diameter of the guide wire tip generally needs to reach about 6 mm. At this time, you can choose the shaping die 101. Take this as an example to expand the instructions for use of the shaper. Place the guide wire to be bent on the layered protrusion 2011, and measure the millimeter scale lines engraved on the layered protrusion 2011 to measure the diameter of the guide wire tip that needs to be bent. The length of the bend is determined, and a marker is used to mark the outer surface of the guide wire. After the shaping die head 10 is separated from the shaping die head 2 102 and the shaping die head 3 103, the triangular insertion hole 106 opened on the shaping die head 101 is connected to the mold plug connector 202, and the guide wire head end is attached to the outer surface of the shaping wood 101. By rotating the No. 2 adjusting rod 213, it is fed into the ear 2 212, so that the No. 2 adjusting rod 213 can drive the pressing block 214 to move. With the help of the guide groove 215, it is ensured that the pressing block 214 can press the outer surface of the guide wire, but not the part of the guide wire head end that needs to be bent. By turning the No. 1 adjusting rod 210 to feed it in the ear 209, the No. 1 adjusting rod 210 can drive the L-shaped support plate 207 to slide on the short rail 206, thereby adjusting the distance between the cylindrical bending head 208 and the shaping die 101. When the cylindrical bending head 208 contacts the outer surface of the guide wire, the handle 205 is turned to make the cylindrical bending head 208 It drives the sliding block 204 to slide in the arc groove 203, so that the cylindrical bending head 208 slides along with the sliding block 204, and cooperates with the shaping die head 101 to bend the guide wire tip into a J shape, and the roundness of the bend can be determined by referring to the angle scale line; after the shaping of the guide wire tip is completed, the handle 205 is released, and the handle 205 can be reset under the action of the tension spring 211, so that the cylindrical bending head 208 can be reset, and then the next guide wire bending and shaping operation can be carried out.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
