Bone cement remote injection system and injection method thereof

Abstract

The invention relates to the technical field of medical equipment, and discloses a bone cement remote injection system and an injection method thereof.The bone cement remote injection system comprises a driving device, a transmission line structure, a driven device and an injection device; wherein a driving wheel structure in the driving device is connected with a driven wheel structure in the driven device through a transmission line structure; the injection device comprises an injector, an injection piston and an injection head; one end of the injector is connected with the injection head through a connecting pipe structure, and the other end is connected with the injection piston through a lead screw structure; the screw rod structure is detachably connected with the driven device through the assembly structure; the driving wheel structure rotates to pull the transmission line structure to drive the driven wheel structure to rotate, so that the screw rod structure is driven to push the injection piston to inject bone cement. By using the bone cement injection system provided by the invention, injection operation can be carried out at a relatively far distance, and adverse effects on the body caused by exposure of medical personnel in an X-ray irradiation environment for a long time in the operation process are avoided.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a bone cement remote injection system and a remote injection method thereof. Background technique [0002] In the field of medical technology, bone cement is a water-soluble polymer compound with excellent performance and wide application. It is a high-tech, high-value-added fine chemical product. Bone cement has a wide range of applications in medicine, and can be used as a glidant for capsules, a cosolvent for injections, a dispersant for liquid preparations, and a stabilizer for enzymes and heat-sensitive drugs. At the same time, bone cement is also a medical material widely used in orthopedic surgery, mainly used for bone filling in artificial joint replacement surgery and vertebroplasty surgery. At present, in orthopaedic operations in major hospitals, bone cement injectors are often used for injection and filling of bone cement. Bone cement starts out like morta...

Problems solved by technology

[0003] During the actual operation, the doctor uses the conventional bone cement injector to fill the following problems: First, during the orthopedic surgery, the doctor takes the bone cement injector into the patient's bone cavity while considering the amount of bone cement injection and the injection channel. Slowly inject bone cement, the operation process is cumbersome, the injection volume is uncontrollable, and the injection volume is not stable enough, which will bring great risks to the operation; in addition, for example, in vertebroplasty surgery, the injection volume and injection location need to use C-arm X-ray perspective It can only be seen that in order to avoid long-term exposure of the human body to the X-ray radiation environment, doctors will choose to leave the operating room when X-rays are needed, or choose to wear heavy protective clothing throughout the operation. The necessary workload also reduces the efficiency of bone cement injection, prolongs the operation time, and increases the patient's pain
