As shown in Figure 1 to Figure 4, this kind of medical suture needle bending machine includes a frame 1, on which there are two sets of opposed clamps. The two sets of clamps are placed on a straight line, and they have the same structure. But in the opposite direction, the structure of the fixture is like this (take the left as an example): A guide tube 2 is installed on the frame 1, the hole of the guide tube 2 is left and right, and a guide plate stands on the left side of the guide tube 2. 3. The plane of the guide plate 3 is in the front and rear direction. A hole is opened on the guide plate 3. The center of the hole and the axis of the hole on the guide tube 2 are on a horizontal line. A guide rod 4 passes through the guide plate 3 and The guide tube 2 can move freely left and right. A horizontal return spring 5 is sleeved on the guide rod 4. The transverse return spring 5 is located between the guide plate 3 and the guide tube 2. A flat plate 7 is fixed at the right end of the guide rod 4, The plate 7 extends in the direction of the guide plate 3, and its whole is located above the guide cylinder 2 and the transverse return spring 5. A roller 7 is installed at the right end of the plate 7. The roller 7 is cylindrical and lays flat in the front and rear directions. Exceed the upper surface of the plate 7, install an adjustment bolt 8 on the plate 7, and then open a long strip hole 10 on a limiting plate 9, pass the adjustment bolt 8 through the strip hole 10, and use a nut to connect the plate 7 and The limit plate 9 is fixed together. The position of the limit plate 9 can be adjusted by adjusting the bolt 8 and the nut. The right end of the limit plate 9 is facing the corner of the operator. A rectangle 11 is removed. The rectangular 11 space of the two clamps is stitched. The placement position of the needle; there is an upper pin 12 between the two rollers 7, the lower end of the upper pin 12 is connected with a longitudinal return spring 13, and two positioning ear plates 14 with holes are installed symmetrically on the upper pin 12 to locate the ear plates 14 is sleeved on the positioning column 15. When the longitudinal return spring 13 is in a relaxed state, the upper end surface of the upper top column 12 is not higher than the upper surface of the roller 7, but just slightly lower than the upper surface of the roller 7, two rollers 7 The distance between them is slightly larger than the maximum distance between the left and right sides of the upper pillar 12. If the upper pillar 12 is a cylinder, the maximum distance refers to the diameter of the upper pillar 12. The positioning column 15 and the longitudinal return spring 13 are both installed on the frame 1. The flat plate 7 can be supported by the support plate 21 on the guide cylinder 2.
如图4所示，上顶柱12部分的动作方式也可以是这样的：在机架1上安装一个柱形筒22，柱形筒22下端可以有底，也可以没有底，然后在柱形筒22内安装一根压簧23，柱形筒22与压簧23固定连接，例如焊接，然后上顶柱12的下端伸入柱形筒22内并与压簧23的上端固定连接。As shown in Figure 4, the action of the upper pillar 12 part can also be like this: a cylindrical barrel 22 is installed on the frame 1. The lower end of the cylindrical barrel 22 may have a bottom or no bottom, and then the A compression spring 23 is installed in the barrel 22, and the cylindrical barrel 22 is fixedly connected with the compression spring 23, for example, by welding, and then the lower end of the upper pillar 12 extends into the cylindrical barrel 22 and is fixedly connected with the upper end of the compression spring 23.
上顶柱12的正上方是一个冲压装置，冲压装置可以是普通的机械结构，也可以是气缸16，气缸16的话，其输出端朝下，并且在其输出端固定一个圆柱形的模具17，这个模具17是平放的，并且前后放置，也就是说其轴心线与导向杆4垂直，模具17的直径大于两个滚轮7松弛状态下的间距，并且模具17位于上顶柱12的正上方，气缸16采用的是脚踏式开关18，放到操作工脚底下，便于操作工控制气缸16的启闭。Right above the upper pillar 12 is a punching device. The punching device can be a common mechanical structure, or a cylinder 16. For the cylinder 16, its output end faces downward, and a cylindrical mold 17 is fixed at its output end. This mold 17 is laid flat and placed back and forth, that is, its axis is perpendicular to the guide rod 4, the diameter of the mold 17 is greater than the distance between the two rollers 7 in the relaxed state, and the mold 17 is located on the upper side of the upper pillar 12 Above, the air cylinder 16 uses a foot switch 18, which is placed under the feet of the operator so that the operator can control the opening and closing of the air cylinder 16.
两个模具17前方是一个操作平台19，操作平台19与平板7的上表面平齐，在才做平台上固定一个L型的操作收纳板20，用于对未折弯的缝合针进行收纳，便于操作。In front of the two molds 17 is an operating platform 19, the operating platform 19 is flush with the upper surface of the plate 7, and an L-shaped operating storage plate 20 is fixed on the working platform for storing unbent suture needles. Easy to operate.
操作过程如下：根据缝合针的长度调整两块限位板9的位置，将缝合针放到操作收纳板的控制范围内，准备操作，将一根直的缝合针当道矩形11空间内，踩下脚踏式开关18，模具17下压，接触到缝合针后继续下压，将缝合针的中部和上顶针一起下压，同时，由于模具17的直径大于两个滚轮7之间的间距，于是模具17也通过滚轮7和平板7推着导向杆4向两边退缩，缝合针的两端则搭在两个滚轮7上，无法下压，从而缝合针被折弯，松开脚踏式开关18，模具17缩回，上顶杆和滚轮7失去压力，在纵向回位弹簧13和横向回位弹簧5的作用下回归原位，折弯好的缝合针也在上顶针的作用下弹出来，这时再进行下一个缝合针的冲压即可。The operation process is as follows: adjust the position of the two limit plates 9 according to the length of the suture needle, put the suture needle in the control range of the operation storage board, prepare for operation, place a straight suture needle in the rectangular 11 space, step on it With the foot switch 18, the mold 17 is pressed down, and after contacting the suture needle, it continues to press down, and the middle part of the suture needle and the upper thimble are pressed down together. At the same time, since the diameter of the mold 17 is larger than the distance between the two rollers 7, so The mold 17 also pushes the guide rod 4 through the roller 7 and the plate 7 to retract to both sides, and the two ends of the suture needle are placed on the two rollers 7 and cannot be pressed down, so the suture needle is bent and the foot switch 18 is released. , The mold 17 is retracted, the upper ejector rod and the roller 7 lose pressure, and return to the original position under the action of the longitudinal return spring 13 and the transverse return spring 5, and the bent suture needle is also ejected under the action of the upper ejector. At this time, press the next suture needle.
除说明书所述技术特征外，其余技术特征均为本领域技术人员已知技术。Except for the technical features described in the specification, the other technical features are all techniques known to those skilled in the art.
