Background technology
Bone cement (i.e. bone cement) is a kind of medical material for bone surgery, due to its part physical property with
And outward appearance and character, quite as white cement for building, there has been so popular title after solidification.Bone cement generally by powder and
Liquid two parts preparation is constituted, when using, according to certain ratio elder generation mix homogeneously, then using bone cement infusion appliance by its
It is expelled to skeleton position.Generally the mixing of bone cement and stirring are carried out in other containers, are reinjected after the completion of mixing
Bone cement infusion appliance, bone cement infusion appliance cannot be directly realized by the purpose of material mix homogeneously, increased operation sequence, and operation is multiple
Miscellaneous, the equipment for using cooperatively is more.
The content of the invention
The bone cement infusion appliance existed to solve prior art cannot realize the defect of the purpose of material mix homogeneously, this
It is bright that a kind of bone cement infusion appliance is provided.
To solve above-mentioned technical problem, the actual technical scheme for being adopted of the present invention for：A kind of bone cement infusion appliance, including
Infusion appliance body has and infusion appliance sheet with the intrinsic piston push rod of the infusion appliance, described infusion appliance body one end is arranged on
The injection nozzle of the cavity connection of body, is placed with movable block, when movable block position in the cavity between the piston push rod and injection nozzle
When injection nozzle one end, there is gap between the movable block and infusion appliance inner body wall, the gap connects the infusion appliance sheet
The cavity and injection nozzle of body.
Preferably, described movable block is spheroid, internal diameter of its diameter less than the infusion appliance body cavity.By thing
Material (powder and liquid) loads after bone cement infusion appliance, rocks bone cement infusion appliance, and spheroid is between piston push rod and injection nozzle
Free movement, plays a part of stirring, mixed material, and movable block is set to into spheroid, and spheroid motion is smooth, advantageously in thing
The uniformity of material mixing.Certainly the movable block of other shapes is equally applicable to the present invention, differs only in mixed effect and mixing
Time.
Preferably, described piston push rod is located at the one end in infusion appliance body cavity body with adaptable with the spheroid
Arc groove.When using the infusion appliance injection bone cement, piston push rod is enabled to as far as possible near injection nozzle, and then
Avoid more bone cement from residing in infusion appliance sheet in vivo, reduce the waste of material.
Preferably, one end inwall that described infusion appliance body is connected with the injection nozzle is tapered, the conical inboard wall
On be provided with some projections, when the spheroid be resisted against it is described projection on when, shape between the spheroid and infusion appliance inner body wall
Into the gap.Upon injection, the bone cement Jing gaps are directed into injection nozzle, it is to avoid the clogging injection nozzle of spheroid.
Further, the duct of some connections is provided with described spheroid.The setting in duct can avoid spheroid from blocking up
While plug injection nozzle, the passage of the injection nozzle of bone cement entrance is increased, improve bone cement injection flow, it is to avoid cause note
Penetrate the big problem of resistance.
Preferably, the duct quantity is three, and three ducts are vertical two-by-two.This kind of setting can be in most less porous
On the premise of road quantity, it is ensured that have a duct to connect with injection nozzle, it is to avoid ball position changes or the rotation in injection is right
The impact that bone cement injection flow is caused, it is ensured that the concordance of injection flow.
Further, for ease of operation, the piston push rod has operation handle away from one end of the injection nozzle.
Further, one end that described infusion appliance body is connected with injection nozzle is provided with installation sleeve, described injection
Mouth is located in the installation sleeve, and the installation sleeve inwall is provided with female thread.Bone cement can be noted using installation sleeve
Enter device to be connected with other equipment, be easy to bone cement to inject human body.
Beneficial effect：Movable block is originally set in vivo in infusion appliance in the application, stirring action can be effectively played, can be direct
The mixing of bone cement material, easy to operate practicality, it is not necessary to which other support the use facility are originally realized in vivo in realization in infusion appliance.

Specific embodiment
Embodiment
As shown in figures 1-4, a kind of bone cement infusion appliance, including infusion appliance body 1 and it is arranged on the infusion appliance body 1
Interior piston push rod 2, the piston push rod 2 has operation handle 21, the infusion appliance body away from one end of the injection nozzle 4
1 one end has the injection nozzle 4 connected with the cavity of infusion appliance body 1, in the cavity between the piston push rod 2 and injection nozzle 4
Movable block is placed with, when movable block is located at 4 one end of injection nozzle, between having between the movable block and the inwall of infusion appliance body 1
Gap, the gap connects the cavity and injection nozzle 4 of the infusion appliance body 1.What described infusion appliance body 1 was connected with injection nozzle 4
