Abstract

The utility model relates to a hand-held bone cement propeller which is mainly used for overcoming the defects of long mounting time with a syringe, difficulty in operation, long injection process of bone cement and the like of the traditional bone cement propeller. The hand-held bone cement propeller comprises a trigger of the propeller, a propelling rod, a connecting rod friction block, a connecting rod return spring, a front cover of the propeller and a cam disk, wherein a link with a puncture needle of the syringe can be rapidly screwed up by clockwise rotating a handle of the propeller. During the process of injecting the bone cement, the trigger of the hand-held bone cement propeller can better control the injection amount of the bone cement, the injection process is stable in action, the mounting time and the injection operation time of the bone cement propeller can be shortened, the bone cement can be prevented from being solidified in the syringe, then the situation that the effective injection amount can not be achieved can be prevented, force is applied to the trigger of the propeller through the finger for injecting the bone cement, the operation is convenient, fast, quantitative and labor-saving, and the stability is good.

Description

A kind of hand held bone cement propeller

Affiliated technical field

This utility model relates to a kind of bone cement propeller, relates in particular to a kind of hand held bone cement propeller.

Background technology

Bone cement propeller in the market is by sleeve pipe, promotes piston, lid, and bail handle combines.During use the bone cement syringe is placed in the sleeve pipe; Need 360 degree rotation bone cement propellers as the turn of the screw, could lid and bone cement propeller be tightened fixing, in injecting the bone cement process; Want 360 degree rotary bar handles, could will promote piston and be pushed into relevant position in the sleeve pipe.But, during through the rotary manipulation bail handle, because of the one hand rotation; Power arm is too short, very requires great effort, and the operator points pain in rotary course; Length consuming time very is being difficult to fast rotational operation bail handle in the effort, in the rotary torsion also variation of love dart stability of making a bet; Also just can not inject bone cement fast, can cause bone cement in syringe, to solidify, seam is excessive and reverse risk of going into blood.

Summary of the invention

In order to overcome the existing angle of rake above-mentioned defective of bone cement, this utility model proposes a kind of hand held bone cement propeller.

The technical scheme that this utility model adopted: a kind of hand held bone cement of this utility model propeller is made up of propeller trigger, pushing ram, connecting rod brake pad, connecting rod back-moving spring, propeller protecgulum, cam disc, utilizes facing directly of cam tooth on the cam disc, when turning clockwise; The empty tube of pushing syringe handle, the empty tube of syringe handle is rotated in a clockwise direction, and the injector screw nipple is screwed in the puncture needle screw socket; When cam disc is rotated counterclockwise, because the inclined-plane of cam tooth can't be rotated counterclockwise by the empty tube of a pushing syringe handle, therefore; When holding bone cement propeller handle left-right rotation, syringe can only rotate according to clockwise direction, thereby makes syringe can screw in the puncture needle screw socket fast; The completion syringe is connected with puncture needle; Utilize lever principle, release with have gentle hands and start shank type bone cement propeller trigger, utilize the leverage of propeller trigger; The drivening rod brake pad; Promote pushing ram forward, and then the pushing syringe piston handle, bone cement injects skeleton accurately, fast, stably the most at last.Avoided to greatest extent that bone cement solidifies, excessive or reverse risk of going into blood, and operated conveniently, stable, quick, laborsaving, control propelling process is effectively controlled injection rate, plays safe effect.

The beneficial effect of this utility model: compare with existing bone cement propeller, a kind of handle type bone cement propeller that this utility model proposes clockwise rotates the propeller handle and can tighten being connected of syringe and puncture needle rapidly; In injection bone cement process, hand held bone cement propeller trigger can better be controlled the bone cement injection volume; Injection process action is stable, shortens the set-up time and the injection operation time of syringe and puncture needle in the bone cement propeller, has prevented that bone cement from solidifying in syringe and do not reach effective injection volume; Bone cement is injected in the reinforcing of finger propeller trigger, and is convenient, quick; Limit the quantity of, laborsaving, good stability.

Among the figure, 1. propeller, 2. propeller trigger, 3. pushing ram, 4. reset handle, 5. connecting rod brake pad of pushing ram; 6. connecting rod back-moving spring, 7. pushing ram back-moving spring, 8. pin, 9, the propeller protecgulum, 10. cam disc, 11. cam tooth; 12. the empty tube of syringe, 13. syringe piston handles, the empty tube of 14. syringes handle, 15. propeller handle pins, 16. link pins, 17. screw thread nipples; 18. the propeller cavity, 19. syringes, 20. propeller handles, 21. bail handles, 22. promote piston, 23. lids.

The specific embodiment

Press the propeller handle 4 that resets, pushing ram 3 is pulled back, syringe 19 is inserted propeller cavity 18, when propeller protecgulum 9 and propeller cavity 18 are screwed; Cam tooth 11 is pressed on the empty tube of the syringe handle 14, when the propeller 1 that turns clockwise, and the empty tube of cam disc 10 fluctuation syringes handle 14; Syringe 19 rotates in the direction of the clock, and when being rotated counterclockwise propeller 1, cam tooth 10 is streaked on the empty tube of syringe handle 14; Syringe 19 does not rotate, continuously about twisting propeller 1, drive syringe 19 and turn clockwise continuously; The puncture needle screw socket can be rapidly with syringe 1 on screw thread nipple 17 be connected, button is held propeller trigger 2, drivening rod brake pad 5; Promote pushing ram 3 drive syringe piston handles 13 and push away forward, the bone cements in the empty tube 12 of syringe through puncture needle injection skeleton, are unclamped propeller trigger 2; Connecting rod back-moving spring 6 resets connecting rod brake pad 5, and button is held propeller trigger 2 continuously, accomplishes the injection of bone cement.

Claims

1. a hand held bone cement propeller is made up of propeller trigger, pushing ram, connecting rod brake pad, connecting rod back-moving spring, propeller protecgulum, cam disc, it is characterized in that hand held bone cement propeller is provided with the cam disc and the propeller trigger of strap cam tooth.
