Abstract
The utility model discloses a long-distance injector for pyramid plastic operations. The needle tube comprises an upper and a lower two independent tubes, wherein the upper tube is a power tube (4), and the lower tube is an injection tube (7), and the power tube (4) of which the upper end is connected with a hydraulic conducting tube (2) and the injection tube (7) of which the upper end is provided with an opening are fixed together through a connecting frame (6). The lower end of a piston rod (5) is fixed with a piston, and a piston (3) is installed in the power tube (4). After the scheme is adopted, medical personnel can remotely operate a far liquid compressing device to carry out pyramid expansion and bone cement injection. After separated from X rays through a lead screen, the utility model can be used for continuously monitoring the degree of pyramid expansion, the dispersing state of bone cement and the leaking condition. Besides, the radiation damage of X rays to medical care personnel can be lowered.
Description
Technical field this utility model relates to a kind of syringe.Be particularly related to a kind ofly in vertebral plasty operation, be used to inject the syringe of air bag and bone cement.
Background technology needs air bag to strut vertebral body and at Intrapyramidal gap injection bone cement when compression fracture of vertabral body is implemented the vertebral plasty operative treatment.Strut in the overall process that vertebral body and bone cement injection operation carry out at air bag, need X ray that guide is followed the tracks of in the injection site all the time, strut degree, bone cement disperse situation and ne-leakage is arranged so that the doctor observes vertebral body.Existing method is for straightforward manipulation under the X line perspective and be interrupted perspective, and not only vertebral body struts degree, and bone cement disperse and seepage situation are difficult to grasp, the prolongation operating time, and also X ray is very big to operator's radiation damage.
Utility model content technical problem to be solved in the utility model provides a kind of long-range syringe that is used for the vertebral plasty operation, is used to overcome the deficiency of above-mentioned prior art and product.The operator that implement the vertebral plasty operation can pass through the lead shield isolated operation at a distance, not only effectively avoid the radiation damage of X ray to medical personnel, continuous X line monitors in the time of also can passing through operation, control vertebral body better and strut degree, bone cement disperse situation and supervision bone cement have ne-leakage.
In order to address the above problem, this utility model has adopted following technical scheme.
A kind of long-range syringe that is used for vertebral plasty operation comprises the piston rod in needle tubing and the syringe, and wherein the needle tubing lower end is connected with puncture needle, and its special feature is: described needle tubing for about independently two by all means, last pipe is the power pipe, following pipe is a syringe; The upper end is connected with between the syringe of the power pipe of hydraulic pressure conducting tube and upper end open and is fixed together by link; Piston-rod lower end is fixed with piston; In the power pipe piston is installed.
The inner and fixed mount that the outer end is used for the bracing frame that is connected with syringe rack fix, and fixed mount is connected with gimbal, and puncture needle is fixed on the gimbal.
The fixedly slide post of puncture needle is installed, with slide post meshed gears and the motor that is used for driven wheel on the gimbal.
The end of hydraulic pressure conducting tube is connected with the liquid pressue device, and described liquid pressue device is any in micro pump, applicator liquid or the syringe.
Link is the macromolecular material piece of an end opening.
After adopting such scheme, the healthcare givers can the remote operation far-end the liquid pressue device implement vertebral body and strut with bone cement and inject, keep apart by lead shield and X ray, sustainable monitoring vertebral body struts degree, bone cement disperse situation and ne-leakage is arranged, and greatly reduce the radiation damage of X ray to medical personnel.
Owing to adopt universal the connection between syringe and the support, can not be subjected to the position, direction restriction of puncture needle and influence fixed firm degree, also can avoid causing the entry needle bending because produce shearing, fractureing.
Description of drawings Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is that structure, the installation of bracing frame, fixed mount and gimbal concerns sketch map.
Fig. 3 is the side view of fixed mount and gimbal.
Fig. 4 is the structural representation of gimbal.
The specific embodiment further specifies this utility model below in conjunction with embodiment.
As shown in Figure 1, embodiment of the present utility model comprises that the upper end is connected with the power pipe 4 of hydraulic pressure conducting tube 2, and the lower end is connected with the syringe 7 of puncture needle 8 and the piston rod 5 that the lower end has piston.In its medium power pipe 4 piston 3 is installed.Contiguous block 6 is the certain elastic macromolecular material piece of an end opening and tool, is used to connect power pipe 4 and syringe 7.Syringe 7 upper end open are so that strut air bag, adding and injection bone cement.
Hydraulic pressure conducting tube 2 is generally flexible pipe, and the length Preliminary design is 5～10 meters.The end of hydraulic pressure conducting tube 2 is a liquid pressue device 1, is compression tube 1 in the example, and directly manual pressure also can be installed auxiliary pressue device, as automatic force (forcing) pump (being similar to micro pump), applicator liquid (being similar to Bone cement gun) etc.Compression tube 1 is generally 5ml with power pipe 4 capacity, is common disposable syringe, and syringe 7 capacity are generally 3～4ml.
Shown in Fig. 2,3, the inner and fixed mount 11 that the outer end is used for the bracing frame 9 that is connected with syringe rack fix, and fixed mount 11 is connected with gimbal 10, and puncture needle 8 is fixed on the gimbal 10.
As shown in Figure 4, the fixedly slide post 14 of puncture needle 8 is installed on the gimbal 10, with slide post 14 meshed gears 16 and the motor 17 that is used for driven wheel 16.Motor 17 is a micro motor, and it is connected with power-supply battery 13 by lead, and the latter is connected with point driving switch 12.Wherein puncture needle 8 is fixed on the slide post 14 by screw 15.
Need the slight puncture needle degree of depth of adjusting in the injection bone cement process, so that the better disperse of bone cement.Operation point driving switch 12, CD-ROM drive motor 17 work, but driven gear 16 rotations, gear 16 and then drive slide post 14 move up and down.Every crawl once can drive puncture needle 8 and advance or move back 1mm.
In injection air bag and bone cement process, after syringe 7 installations, power pipe 4 is connected by fixed block 6 with syringe 7, start X-ray machine, the healthcare givers observes under lead shield is isolated on one side, Yi Bian handle liquid pressue device 1, liquid is pressed in the power pipe 4 by hydraulic pressure conducting tube 2.Piston rod 5 is at the upper end piston, and promptly piston 3 suppressing actions in the power pipe 4 promote downwards down, and air bag or bone cement are injected into operative site, finishes vertebral body and struts with bone cement and inject.
Need to prove, compression tube 1, power pipe 4 equate theoretically with the injection volume of syringe 7, but power pipe 4 inner carriers 3 generally have certain interval with syringe 7 inner piston rods 5, will eliminate this part gap during operation, just can reach the perfect condition that the three equates.
