The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
Described operation on vertebra knife system, mainly comprises three assemblies: operation on vertebra cutter, guide needle and puncture needle.Wherein, guide needle is mainly used in guiding operation on vertebra cutter into need to implement operation particular location, and puncture needle is for guide needle being taken to sufferer place, and the location that completes guide needle, and operation on vertebra cutter completes concrete operation and implements.Respectively above-mentioned three assemblies are illustrated one by one below.
Described operation on vertebra cutter comprises front-end and back-end two parts, and as described in Figure 1, front end comprises wire electrode 1, dynode 2 and the outer utmost point 3, between wire electrode 1 and dynode 2, between dynode 2 and the outer utmost point 3, be provided with insulator, forms insulating barrier 4.Specifically, as shown in Figure 4 and Figure 5, the overall curved shape of wire electrode 1, its two ends all with the power line conducting of rear end, the electrode needing to produce operation, and the maximum path length of wire electrode is no more than the diameter of the outer utmost point; Dynode and the outer utmost point are stainless steel capillary, and diameter is identical, and for improving safety, the surface of the utmost point also arranges an insulating barrier outside.The difference of Fig. 4 and Fig. 5 is, the shape difference of wire electrode, and this is to design in order to adapt to different sufferer shapes, certainly, also wire electrode can be designed to other shapes, this technology does not limit this.The rear end of operation on vertebra cutter comprises the first plastic 5, the second plastic 6 with the first plastic 5 clampings, front end passes the second plastic 6, the first plastic 5, the outer utmost point 3, dynode 2 afterwards and the power line 8 of wire electrode 1 conducting successively, the attaching plug 9 being electrically connected with the rear end of power line 8.In addition, in order to ensure the connection safety of power line, in the junction of power line 8 and the second plastic 6, also thermoplastic has a heat-shrink tube 7.Heat-shrink tube 7 can select rubber or silica gel to be made.
As shown in Figure 2, described guide needle is mainly made up of stainless steel tube 10 and the 3rd plastic 11.The slightly larger in diameter of stainless steel tube 10, in the diameter of the outer utmost point 3, can allow the outer utmost point 3 smoothly through stainless steel tube 10, arrives sufferer place; The 3rd plastic 11 is fixed on the end of stainless steel tube 10, for being connected with puncture needle with operation on vertebra cutter, realizes supporting.Be provided with scale at stainless steel tube 10, location teething ring 12 is installed simultaneously, location teething ring 12 can slidably reciprocate on stainless steel tube 10, and while sliding into appropriate location, also stainless steel tube 10 can be located.
As shown in Figure 3, described puncture needle comprises stainless pin 13, and is fixed on the plastic head 14 of stainless pin 13 ends, and is connected to the 4th plastic 15 of plastic head 14 outsides.The path length of stainless pin 13 equates with the path length of the outer utmost point 3, all can penetrate in stainless steel tube 10.The 4th plastic 15 is for coordinating with the 3rd plastic 11, and when work, both are threaded.
When use, first the stainless pin of puncture needle 13 is penetrated in the stainless steel tube 10 of guide needle, and stretch out, then the 4th plastic 15 and the 3rd plastic 11 are connected firmly, the sufferer place that inserts together vertebra, determines after particular location, utilizes location teething ring 12 that guide needle is stuck in to sufferer place; Then take off puncture needle, the front end of operation on vertebra cutter penetrated in stainless steel tube 10, and make wire electrode 1 extend out to stainless steel tube 10 outsides, then the first plastic 5 is connected with the 3rd plastic 11 fastening, as shown in Figure 6.Now, the location work of whole operation on vertebra has just completed, and only attaching plug 9 need to be accessed to power supply, can come into effect operation.
This utility model principle is simple, easy to operate, no longer need to rely on doctor's experience to position, can quickly and accurately operation on vertebra cutter be guided to sufferer place, implement operation, the problem that there will not be scalpel to depart from, had both improved the convenience of operation, also the difficulty that has reduced operation, has very high practical value.
Above-described embodiment is only preferred embodiment of the present utility model; the not restriction to this utility model protection domain; in every case adopt design principle of the present utility model, and carry out non-creativeness work on this basis and the variation made, within all should belonging to protection domain of the present utility model.
