Abstract

The invention relates to a multi-angle tumor medicine injector. The multi-angle tumor medicine injector comprises a needle cylinder, a plug arranged below the needle cylinder, a needle inserted into the plug, a needle hole formed in the lower end of the needle, a piston inserted into the needle cylinder in a sliding mode, a piston rod fixed to the piston, and a pressing head arranged at the head end of the piston rod. The multi-angle tumor medicine injector further comprises multiple sliding blocks arranged in the needle and located above the needle hole, multiple sliding plates inserted into sliding block sliding holes in a sliding mode, and elastic reset devices installed on the sliding plates. After the needle is inserted into a tumor, the pressing head is pressed to push the piston to move downwards so that liquid medicine in the needle cylinder can be injected into the tumor from the needle hole. A power device drives the sliding plates in designated positions to move so that through holes I and through holes II can coincide with one another, the liquid medicine can be sprayed out to other positions of the tumor from the needle along the through holes II, and the situation that pain of a patient is increased due to repeated puncture is effectively avoided.

The present invention is in order to overcome the deficiency of above technology, and providing a kind of once penetrating can the multi-angle tumor medicine injecting device of multidirectional injection.
The present invention overcomes the technical scheme that its technical problem adopts:
This multi-angle tumor medicine injecting device, comprise syringe, be arranged at the plug below syringe, be plugged in the syringe needle on plug, be arranged at the pin hole of syringe needle lower end, slide the piston be plugged in syringe, be fixed on the piston rod on piston and be arranged at the press head of piston rod head end, also comprise and be arranged at syringe needle, be arranged at needle wall and be positioned at the some slide blocks above pin hole, slide the some slide plates be plugged in slide block slide opening and the elasticity reset device be installed on slide plate, described slide plate is provided with some open-works I, described syringe needle outer wall is provided with the open-work II corresponding with open-work I with the slide plate place of matching, in its natural state, described elasticity reset device drives the open-work I on slide plate to close with corresponding open-work II mutual dislocation, power set are arranged in syringe needle, the open-work I on slide plate and corresponding open-work II mutual conduction is driven successively in its rotary course.
Above-mentioned elasticity reset device comprises some spring leafs and is arranged at the some projections in syringe needle, and slide plate lower end is fixed in described spring leaf upper end, its lower end be fixed on relative to projection on, described spring leaf convexes to form circular arc to the position of center line of syringe needle.
Above-mentioned power set comprise the screwed hole be arranged in syringe needle, to be combined in screwed hole by external screw thread and the swivel head being positioned at each slide plate upper end, the spline that is fixed on the drive rod above swivel head and is arranged on drive rod, described drive rod is once through plug, piston, piston rod and press head, and it is plugged in piston, piston rod and press head by spline slide, described swivel head is provided with some liquid pass holes, and lower end is provided with inclined-plane.
The invention has the beneficial effects as follows: when syringe needle is inserted into after in tumor, piston can be promoted after pressing press head and move down the medicinal liquid in syringe is expelled in tumor from pin hole.Driving the slide plate of assigned address to move by power set makes open-work I overlap with open-work II, thus medicinal liquid can be made from syringe needle, to be ejected into other positions of tumor along open-work II, the increase of patient suffering's property that effectively prevent repeatedly punctures causes.

Detailed description of the invention
Below in conjunction with accompanying drawing 1, the present invention will be further described for accompanying drawing 2.
This multi-angle tumor medicine injecting device, comprise syringe 13, be arranged at the plug 14 below syringe 13, be plugged in the syringe needle 1 on plug 14, be arranged at the pin hole 2 of syringe needle 1 lower end, slide the piston 15 be plugged in syringe 13, be fixed on the piston rod 16 on piston 15 and be arranged at the press head 18 of piston rod 16 head end, also comprise and be arranged at syringe needle 1, be arranged at syringe needle 1 inside and the some slide blocks 5 be positioned at above pin hole 2, slide the some slide plates 6 be plugged in slide block 5 slide opening and the elasticity reset device be installed on slide plate 6, slide plate 6 is provided with some open-works I 7, syringe needle 1 outer wall is provided with the open-work II 8 corresponding with open-work I 7 with slide plate 6 place of matching, in its natural state, elasticity reset device drives the open-work I 7 on slide plate 6 to close with corresponding open-work II 8 mutual dislocation, power set are arranged in syringe needle 1, the open-work I 7 on slide plate 6 and corresponding open-work II 8 mutual conduction is driven successively in its rotary course.When syringe needle 1 is inserted into after in tumor, piston 15 can be promoted after pressing press head 18 and move down the medicinal liquid in syringe 13 is expelled in tumor from pin hole 2.Driving the slide plate 6 of assigned address to move by power set makes open-work I 7 overlap with open-work II 8, thus medicinal liquid can be made from syringe needle 1, to be ejected into other positions of tumor along open-work II 8, the increase of patient suffering's property that effectively prevent repeatedly punctures causes.
Some projections 3 that elasticity reset device comprises some spring leafs 4 and is arranged in syringe needle 1, slide plate 6 lower end is fixed in spring leaf 4 upper end, its lower end be fixed on relative to projection 3 on, spring leaf 4 convexes to form circular arc to the position of center line of syringe needle 1.When slide plate 6 moves down, its compression spring leaf 4 becomes curved, because spring leaf 4 protrusion direction is towards center, it is hereby ensured the flexural deformation of spring leaf 4, is closed by open-work II 8 to guarantee that slide plate 6 can pop up smoothly when return.
The swivel head 9 that power set are comprised the screwed hole 11 be arranged in syringe needle 1, are combined in screwed hole 11 by external screw thread and are positioned at each slide plate 6 upper end, the spline 17 being fixed on the drive rod 12 above swivel head 9 and being arranged on drive rod 12, drive rod 12 is once through plug 14, piston 15, piston rod 16 and press head 18, and it is plugged in piston 15, piston rod 16 and press head 18 by spline 17 slip, swivel head 9 is provided with some liquid pass holes 10, and lower end is provided with inclined-plane.Owing to adopting spline joint, therefore 10 rotation of drive rod 12 driven rotary can be driven by rotating press head 18, because swivel head 10 baseplane is inclined-plane, therefore it is by threads turn, it can be moved downward and be promoted downwards by the slide plate 6 of inclined-plane minimum point by proximity, until open-work I 7 and open-work II 8 coincide.Next group slide plate 6 can be driven after again rotating beyond this slide plate 6 to move downward, and structure is simple, easy to adjust, can be opened by the open-work of Spin Control required direction, thus completes the work of injection hydrojet.
