Problems solved by technology

[0005] The main disadvantages of the type II bone cement injection device with the above structure are: there will inevitably be non-directional factors when the bone cement is filled. The side of the diseased vertebral body will be more or less under certain pressure, causing the side of the diseased vertebral body to protrude outward, which is very likely to aggravate the degree of fracture of the diseased vertebral body, not only does not achieve the expected surgical effect, but may aggravate the patient's pain. pain

Abstract

A type-II bone cement injection device comprises a probe sleeve. A grip is disposed at the tail end of the probe sleeve. The front end of the probe sleeve is provided with a serrated-edge opening which is communicated with an inner passage of the probe sleeve. The type-II bone cement injection device is characterized in that the grip is provided with a Luer taper, a connector of the Luer tape is communicated with the inner passage of the probe sleeve, and one side of the probe sleeve, close to the serrated-edge opening, is provided with an injection outlet which is communicated with the inner passage of the probe sleeve.

Description

technical field [0001] The invention relates to the field of orthopedic medical devices, in particular to a type II bone cement injection device used in vertebral body balloon dilatation and plastic surgery. Background technique [0002] Balloon vertebroplasty is a minimally invasive spinal surgery, mainly used in the treatment of vertebral compression fractures, which is the most common complication in patients with osteoporosis, causing local pain and mobility impairment In severe cases, it can also lead to paralysis of the lower limbs. Balloon dilatation of the vertebral body first expands the height of the damaged vertebral body through balloon expansion, and then injects bone cement and other fillers into the diseased vertebral body for filling, thereby enhancing the strength and stability of the diseased vertebral body and enabling recovery. The posterior vertebral body will no longer be compressed and deformed. [0003] Type II bone cement injection device is one of...
