Detailed Description
The following detailed description of specific embodiments of the invention is provided to facilitate a further understanding of the invention.
The utility model provides a novel pipe is implanted to implantable bent angle centrum shaping device, includes the peek implantation tube, the peek implantation tube includes handle 1 and body 2, and the one end and the 1 detachably of handle of body 2 are connected, other end bending type becomes curved portion 3, has seted up a plurality of bone cement mud outlet hole 4 on the curved portion 3, and the curved portion can cut off and remain internally through the cutting off department 10 of 5 front ends of sleeve pipe passageway. The plurality of cement grout outlet holes 4 of the bending portion 3 are directed in a plurality of different directions. The advantage of this is that bone cement can diversely fill after 4 blowout from bone cement mud outlet, and it is more even to fill, and it is effectual to fill.
Further, the peek implantation tube is detachably disposed in the cannula passage 5, and the bending portion 3 can be protruded out of the cannula passage 5 and cut off through the cutting portion 10 at the front end of the cannula passage 5.
Furthermore, the device also comprises a bone drill 6, an expander 7 and a puncture needle 8, wherein the expander 7 is detachably sleeved outside the puncture needle 8, the sleeve channel 5 is detachably sleeved outside the expander 7, and the bone drill 6 is detachably sleeved inside the sleeve channel 5. The device further comprises a positioning tab 9 for positioning. The puncture needle comprises a handle and a needle head which are detachably arranged.
The operation process is as follows:
after the positioning sheet is positioned, the puncture needle is used for puncturing, the handle of the puncture needle is taken down after puncturing, the dilator is installed, and the sleeve pipe channel is installed on the outer side of the dilator; taking out the puncture needle and the dilator, then installing the bone drill in the cannula channel and drilling the bone by using a drill bit at the front end of the bone drill; taking out the bone drill, installing the peek implantation tube in the sleeve channel for bone cement filling, and enabling the bent part at the front end of the peek implantation tube to extend out of the sleeve channel; after the perfusion is finished, the bent part of the peek implantation tube is cut off by utilizing the cut-off part at the front end of the sleeve channel, and the bent part forms a crotch-shaped structure and is retained in the body.
The device of the application overcomes a series of problems of long operation time, more radioactive ray exposure, increased puncture risk, increased cost and the like of the traditional double-side puncture operation. The technical advantages are as follows: single-side puncture and double-side reinforcement; the risk of puncture complications is reduced by half; reducing half of the operator intraoperative X-ray exposure; the unique bent angle opening design reduces the leakage of bone cement; the multi-point injection and the uniform reinforcement are more in accordance with the biomechanical reconstruction of the human body.
Although the present invention has been described with reference to the above embodiments, it should be understood that the present invention is not limited thereto, and various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
