Detailed description of the invention
Below in conjunction with brief description of the drawings detailed description of the invention of the present utility model,
Fig. 1 is the structural representation of the pedicle screw implanting device of this utility model embodiment.As shown in Figure 1, pedicle screw implanting device 100, comprises center open cell 1, outer sleeve 2, and seal wire 3.
Fig. 2 is the schematic diagram of the center open cell of the pedicle screw implanting device of this utility model embodiment, and Fig. 8 is the circuit diagram of pedicle screw implanting device of the present utility model.As shown in Figure 2 and Figure 8, center open cell 1 has convex handle 4, bar portion 5, and convex handle 4 inside have current sense link plate 6 and acoustic-optic alarm 7, and bar portion 5 comprises central electrode 8, periphery electrode 9 and insulating barrier 10.As shown in Figure 3 and Figure 4, central electrode 8 is positioned at central authorities, and insulating barrier 10 holds central electrode 8, and periphery electrode 9 holds insulating barrier 10.Central electrode 8 and periphery electrode 9 are the metal material of conduction, and insulating barrier 10 is insulant.Insulating barrier 10 makes mutually insulated between central electrode 8 and periphery electrode 9.The front end of center open cell 1 is coniform, in order to open a way before implanting pedicle screw.Central electrode 8, periphery electrode 9, insulating barrier 10 run through whole bar portion 5, are finally connected in convex handle 4.Central electrode 8, periphery electrode 9 are connected with current sense link plate 6 respectively, current sense link plate 6 is powered by the power supply 15 of convex handle 4 inside, between central electrode 8 and periphery electrode 9, can form circuit loop by surrounding tissue and current sense link plate 6.Current sense link plate 6 is common commercial prod.Central electrode 8 and periphery electrode 9 respectively with the first electrode column 14 be connected with the second electrode column 13, the first electrode column 14 is connected respectively wire with the second electrode column 13, the tail end of wire has binding post, can insert in the wire inserting slot of current sense link plate 6, acoustic-optic alarm 7 is connected with current sense link plate 6, can, according to curent change in circuit, make different acousto-optic hints.In the time that central electrode 8 penetrates or penetrates cortical bone, there is larger variation in the resistance of the circuit loop between it and periphery electrode 9, affect the electric current in loop, in the time that electric current in loop occurs to change suddenly, current sense link plate 6 can be connected the switch of report acousto-optic alarm devices 7, causes that acoustic-optic alarm 7 reports to the police.Prompting nail road track mistake, now operator should be according to pointing out shut-down operation immediately, in case Spinal Cord and nerve.In convex handle 4, there is power supply 15 and provide electric energy for whole circuit.
Fig. 5 is the schematic diagram of the pedicle screw implanting device outer sleeve of this utility model embodiment.As shown in Figure 5, outer sleeve 2 has pipe portion 11 and spill handle 12 two parts, the external diameter of the bar portion 5 of center open cell 1 is identical with the pipe portion internal diameter of outer sleeve 2, and outer sleeve 2, compared with the short 2mm of the length of center open cell 1, can expose the tip of center open cell 1.Between outer sleeve 2 and center open cell 1, there is insulating barrier.The convex handle 4 of the spill handle 12Yu center open cell 1 of outer sleeve 2 agrees with mutually, what Fig. 6 showed is the rearview of convex handle 4 while rotating with respect to spill handle 12, spill handle 12 rear portions have opening, this opening can only could pass through in the time of convex handle 4 90-degree rotation, thereby center open cell 1 and outer sleeve 2 are separated.The external diameter of seal wire 3 is identical with pipe portion 11 internal diameters of outer sleeve 2, after available nail road is successfully established, extracts center open cell 1, inserts seal wire 3, takes off outer sleeve 2, and the pedicle screw of hollow is enclosed within on seal wire 3, and guiding screw is screwed into pedicle of vertebral arch.
When use, first whole device is carried out disinfection, the outside of operator grasps spill handle 12 operates, and as shown in Figure 7, the head of center open cell 1 enters after tissue, and acoustic-optic alarm 7 starts to send low frequency alarm sound.When spongy bone is left at the head tip of center open cell 1, when penetrating or passing cortical bone, the central electrode 8 of device head is positioned at different tissues with periphery electrode 9, make the resistance in circuit occur sharply to change, cause that unexpected variation occurs electric current, alarm sends high frequency alarm sound, and prompting channel errors should stop immediately and change passage, in case Spinal Cord and nerve.Owing to thering is certain gap between the cortical bone on vertebral foramen arm and its inner spinal cord, therefore in the time that cortical bone has just been broken through in the tip of open cell, also have certain distance apart from spinal cord, now send the most advanced and sophisticated Spinal Cord of head that warning can be avoided center open cell 1 completely.
Embodiment effect and effect
According to pedicle screw implanting device of the present utility model, because the different caused curent changes of resistance that utilized different tissues are reported to the police, therefore can effectively survey the residing position, implantation hole of operation pedicle screw, remind in time user, damage intrinsic nerve tissue etc. after preventing from penetrating cortical bone.
In addition, after combination between convex handle and spill handle, by rotating 90 dismountings, therefore this utility model is more firm in use procedure.
