Problems solved by technology
Obviously, there is no risk of leakage in the implantation of solid objects, which represents the direction of future development. However, there are many lumens and gaps in the vertebroplasty applied to implantation of solid objects, and it is difficult to clean. Repeated application may have the risk of disease transmission. risk

Embodiment Construction
[0021] like Figure 1~4 A self-destructing vertebroplasty device shown includes an instrument part 1 on which an implant rod 2 is connected. Considering the convenience of operation, a handle 8 is provided on the instrument part 1, which is unique The difference lies in that a limiting spring 23 is arranged inside the instrument part 1 adopted in the present invention, and the instrument part 1 also includes an insertion tube 4 . Specifically, in order to facilitate correct guidance and ensure smooth implementation, a guide tube 3 is connected to the insertion tube 4 , and a catheter 6 is arranged inside the guide tube 3 . Simultaneously, the inserting rod 5 is pierced in the inserting tube 4, the self-destructing mechanism 7 is connected on the described conduit 6, and the self-destructing rod 22 is connected on the described self-destructing mechanism 7, and the described self-destructing rod 22 One end is distributed with a self-destruction block 24, the inner wall of the ...

The invention relates to a self-destructing vertebroplasty device, which includes an instrument part, an implant rod is connected to the instrument part, and a handle is arranged on the instrument part. The insertion tube is connected with a guide tube. At the same time, a catheter is arranged in the guide tube, an insertion rod is pierced in the insertion tube, a self-destruction mechanism is connected to the catheter, and a self-destruction rod is connected to the self-destruction mechanism. In addition, a self-destruct block is distributed at one end of the self-destruct rod, and a guide groove is provided on the inner wall of the conduit. Both the self-destruct rod and the self-destruct block are installed in the guide groove, and a limit spring is arranged between the self-destruct rod and the self-destruct block to form an anti-contact spacing. As a result, the vertebral body can be effectively formed by cooperation of the instrument part and the implant rod. A self-destruct mechanism is adopted to prevent repeated use and avoid the possibility of disease transmission. Moreover, the overall structure of the present invention is simple, easy to manufacture, assemble and use, and easy to popularize.
Description
technical field [0001] The invention relates to a shaping device, in particular to a self-destructing vertebral body shaping device. Background technique [0002] Vertebroplasty is a new minimally invasive spinal surgery, mainly used to treat vertebral compression fractures in osteoporosis, primary or metastatic vertebral tumors and other diseases. At present, the main technical methods are: 1. Liquid Material injections include non-revivable bone cement and rejuvenable bone slurry. Bone cement injection can be divided into percutaneous vertebroplasty and kyphoplasty according to whether the vertebral body is stretched. The former is to inject bone cement into the vertebral body without space under high pressure conditions; the latter is to inject bone cement through bone expansion. The expansion of the apparatus in the vertebral body produces a cavity, and the bone cement is injected into the cavity of the vertebral body under low pressure, and the leakage is relatively li...
