Integrated bone cement injection device with stirring function and injection function

Abstract

The invention relates to the field of medical instruments and discloses an integrated bone cement injection device which comprises a needle cylinder, a push-pull assembly and a stirring assembly. The front end of the needle cylinder is detachably connected with a plug assembly achieving a closing effect. The rear end of the needle cylinder is detachably connected with a handheld grip assembly. The push-pull assembly comprises a push-pull rod, a push-pull handle and a piston with a sealing ring. The stirring assembly comprises a stirring rod, a stirring handle and a stirring piece. A stirring assembly and a push-pull assembly are arranged at two ends of the needle cylinder, stirring and push-pull injection action can be finished within one needle cylinder, injection can be conducted by installing a puncture device after stirring, the shortcoming that bone cement falling on the outside generates pungent odor and reproduction of bone cement causes waste, the operation time is reduced, the burden of doctors is reduced, a doctor can finish various operations in a surgery easily, accidents in the surgery are reduced, and the surgery quality can be improved.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to an integrated bone cement injector with stirring and pouring functions. Background technique [0002] In orthopedic surgery, it is often necessary to perfuse the patient after stirring the bone cement, but the process of stirring and perfusing the bone cement is complicated, requiring the doctor to be familiar with the characteristics of the bone cement and to be able to accurately grasp the timing during the operation, but due to Due to the nature of the bone cement itself, the operation process only takes a few minutes, and the mixing and perfusion steps are relatively short, which is prone to uneven mixing. [0003] In addition, the entire operation process is very hasty, requiring high skill and mental concentration of the doctor, and the surgical situation is complex and changeable.

Problems solved by technology

[0002] In orthopedic surgery, it is often necessary to perfuse the patient after stirring the bone cement, but the process of stirring and perfusing the bone cement is complicated, requiring the doctor to be familiar with the characteristics of the bone cement and to be able to accurately grasp the timing during the operation, but due to Due to the nature of the bone cement itself, the operation process is only a few minutes, and the mixing and perfusion links are relatively short, which is prone to uneven mixing

[0003] In addition, the entire operation process is very hasty, requiring high skill and mental concentration of the doctor, and the surgical situation is complex and changeable. If you are not careful, you may not be able to grasp the best timing, so you have to re-adjust the bone cement, which increases the risk of surgery. The pain of the patient is reduced, and the doctor needs to go through the above-mentioned operation process again, so the workload can be imagined; and the re-modulation of the bone cement also causes a waste of materials

[0004] The existing bone cement mixing methods are divided into two types, one is manual stirring, and manual stirring is carried out in a container with a stirring rod, which is prone to uneven stirring, and the viscosity is not easy to control, which affects the stirring efficiency

The other one needs to be mixed with a motor, which requires a motor, a control box for controlling the motor, and a vacuum device for vacuuming. Its structure is complicated and it is not convenient to use on the surgical site.
