It further, further include the actuating for opening the driving means of interval in the conduit in the essence note step When the bone cement of middle receiving cannot continue to enter injection site from the outlet by the extruding of the protrusion substantially, to the conduit Middle a certain amount of bone cement of supplement is to continue to inject.

The advantages of the technical program, is as follows.

The quantitative bone cement of extruding offer, which is carried out, by the burr of mandrel greatly improves quantitative accuracy.

Specific embodiment

Below with reference to embodiment, the present invention is described in further detail, and embodiments of the present invention are not limited thereto.

Embodiment one.

A kind of bone cement injection control apparatus, described device include: the entrance with the bone cement base portion and with Base portion separates and the injection needle of the outlet with the bone cement;It further includes be attached to the base portion and the injection needle outer Shell.Or at least one directly by the base portion, the injection needle constitutes the part of the shell.Here base portion and injection The shell shape of needle can be set according to the occasion of specific implementation weight feed, such as by the shell structure of base portion and injection needle It makes as handle shape.The base portion be also connected with one for bone cement push driving means, driving means can for manually or Person is electronic, such as is configured to syringe, is sent by hand push so that bone cement enters the conduit;

It also has an elastically deformable and partially transparent conduit, and the tube at one end and the entrance fluid connect The logical and other end and the communication;This conduit can be the conduit of plastics or general macromolecule material, It can be deformed so that the paste-like bone cement wherein passed through advances to gush out from injection needle.The transparent part of conduit is longitudinal The amount that bone cement in conduit is observed through entire conduit substantially.

And the burr at least one screw shape for being used to drive the bone cement being contained in the conduit Live spindle, one end of the mandrel is rotationally attached to the base portion, and the part enclosure of mandrel can be fixed here It is connected on base portion and makes its limit installation, mandrel belongs to common connection firmware, and specific mounting means is no longer superfluous here It states, and the other end of the mandrel is rotatably attached or that fixes is attached to the injection needle;The setting of screw can be with Supply precision as needed changes the size of its outer diameter, such as when needing bigger precision using outside lesser screw thread Diameter, so that the bone cement that rotary squeezing goes out every time is less.

The conduit is also equipped with a support backing, the support backing to be located at the mandrel and the support backing it Between at least part and the mandrel extruding of one section of conduit contact;

And a drive shaft being connected with mandrel, for driving the rotation of the mandrel, which can be set It sets on base portion, so that the bone cement for the pasty consistency being contained in the conduit by the screw driving of the mandrel gushes To the outlet.Drive shaft can be by connecting the stepper motor being arranged in inside base portion come so that the flow gushed out every time can Control, the amount for the bone cement gushed out is controlled by programming.

Further, wherein the support backing includes the shell for the conduit, so that on the support backing The conduit be supported so that screw and the tubular conduit extruding of mandrel contact.And in the present embodiment wherein The mandrel has the uncontinuous spiral line for discontinuously driving the bone cement.Alternatively, the mandrel has band There is the screw of bending part.Here backing can have the screw thread substantially cooperated with the screw, so that Two sides carry out corresponding extruding simultaneously.

Further, wherein the conduit and the support backing are integrated in the same component.Or it wherein described leads Pipe and the support backing are independent components.And wherein the support backing by the material of elastically deformable be made for example with Conduit uses the same or similar material.

Change its shape with specific reference to application scenarios.The shell includes one or more spiral shells for running through the shell The head of nail, the screw is reachable from the outside of shell, and end reaches the support backing.In this way can by screw come The compressing dynamics for adjusting backing needs to carry out screw operation especially after present apparatus access times are more to continue it and squeeze The degree of press contacts.

In this example, wherein the drive shaft is flexible, it is used for the driving between actuator motor and the mandrel Connect the manual orientation to allow described device.In this way when supply paste-like bone cement enters complicated region, hand can be passed through Base portion and injection needle are held to change the direction of output to carry out injection operation to the part performed the operation.Specifically injecting When include: two steps of thick note and smart note, the thick note step includes activating the driving means by described and forcing the bone Cement passes sequentially through the entrance, conduit and outlet and enters injection site to complete most of dosage of the bone cement injection Injection;The essence note step include stop or suspend the actuating of the driving means, and by continue or intermittently open described in Drive shaft described in actuating motor driven drives the mandrel to rotate, and then is forced and led to the extruding of the conduit by the protrusion The bone cement basal ration accommodated in pipe enters injection site from the outlet.Further, it is also wrapped in the essence note step The actuating for including the unlatching driving means of interval cannot be continued substantially with the bone cement accommodated in the conduit by described convex When the extruding risen enters injection site from the outlet, a certain amount of bone cement is supplemented into the conduit to continue to inject.This Sample first substantially injection for example push injection 90 or more percent bone cement amount, then by control mandrel rotation come Accurately inject subsequent part.

Embodiment two.
