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

Abstract

The invention relates to the technical field of medical equipment, and provides a bone cement injection device. The bone cement injection device comprises a support, a bone cement injection executing mechanism and a far-end handheld control mechanism, wherein the bone cement injection executing mechanism is arranged on the support and used for injecting bone cement; and the far-end handheld control mechanism is connected with the bone cement injection executing mechanism through a flexible connecting mechanism, the far-end handheld control mechanism comprises an action part, and the action part acts to drive the bone cement injection executing mechanism to act through the flexible connecting mechanism so as to inject the bone cement. According to the bone cement injection device, the action part of the far-end handheld control mechanism is remotely operated to act, the bone cement injection executing mechanism is driven by the flexible connecting mechanism to synchronously act, remote operation of bone cement injection is carried out, surgical workers are far away from X-ray irradiation, and the influence of X-ray irradiation on the body of a doctor during an operation is greatly reduced.

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...
