Problems solved by technology

[0007] 2) Manually turn the handle, unable to accurately control the moving distance of the push rod, which means that it is impossible to manually accurately control the injection volume of the syringe
[0008] 3) When manually injecting bone cement, due to individual differences, the injection pressure of the syringe cannot be precisely controlled manually, resulting in an unsteady injection process

Embodiment Construction

[0052] A kind of bone cement injection device of the present invention is described in detail below in conjunction with accompanying drawing:

[0053] Such as Figure 1-5 As shown, the bone cement injection device of this embodiment includes:

[0054] bracket 1;

[0055] The bone cement injection actuator 3 is set on the bracket 1 and is used for bone cement injection;

[0056] And the remote hand-held control mechanism 2 is connected to the bone cement injection actuator 3 through a flexible connection mechanism;

[0057] The remote hand-held control mechanism 2 includes an action part, and the action of the action part drives the action of the bone cement injection actuator 3 through the flexible connection mechanism to perform the bone cement injection operation.

[0058] The bone cement injection actuator 3 of the bone cement injection device in this embodiment is set on the bracket 1, and the bone cement injection actuator 3 can be set at a designated position for bone...

Abstract

The invention relates to the technical field of medical equipment, and provides a bone cement injection device, including: a bracket; a bone cement injection actuator, which is arranged on the bracket and used for bone cement injection; and a remote hand-held control mechanism, which is connected by a flexible connection mechanism The bone cement injection actuator; the remote hand-held control mechanism includes an action part, and the action of the action part drives the bone cement injection actuator to move through the flexible connection mechanism to perform the bone cement injection operation. The bone cement injection device of the present invention operates the action parts of the remote hand-held control mechanism at a long distance, drives the bone cement injection actuator to act synchronously through the flexible connection mechanism, and performs remote operation of bone cement injection, so that surgical workers are far away from X-rays. Radiation greatly reduces the impact of intraoperative X-ray radiation on the doctor's own body.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a bone cement injection device. Background technique [0002] Bone cement is a water-soluble polymer compound with excellent performance and a wide range of uses. It is a high-tech, high-value-added fine chemical product. Bone cement is widely used 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. Bone cement is also a medical material used in orthopedic surgery, mainly used in artificial joint replacement surgery and vertebroplasty for bone filling. At present, in orthopedic operations in major hospitals, bone cement injectors are often used to inject and fill bone cement. Bone cement begins to resemble mortar, which can be kneaded and extruded into any shape, and then solidifies gradually. Before it hardens, the doctor puts it in the place w...
