Description
Technical Field
The utility model relates to a medical bone cement injection device for minimally invasive surgery, which belongs to the technical field of medical instruments and utility model.
Background
Vertebroplasty is a minimally invasive spinal surgery technique of percutaneous puncture and injection of bone cement into a diseased vertebral body through a pedicle or an extrapedicular approach, and is mainly applied to treatment of osteoporotic vertebral compression fracture. The vertebral compression fracture is the most common complication of osteoporosis patients, can cause local pain and movement disorder, can also cause paralysis of lower limbs seriously, and is one of the common orthopedic diseases of the old patients.
The vertebroplasty firstly makes an incision with the length of about 2mm on the back of a patient, then enters a diseased centrum through skin puncture under the monitoring of X-rays by using a special puncture needle, establishes a working channel, and finally injects fillers such as bone cement and the like into the centrum to stabilize the fractured centrum, thereby achieving the purposes of increasing the strength and stability of the centrum, preventing collapse, relieving pain and reducing complications of bed rest, and also recovering partial height of the centrum to a certain degree.
At present, the types of commonly used bone cement injectors are various, and the bone cement injectors produced by different manufacturers have defects of different types and degrees. The bone guide is generally hand-held and comprises four parts, namely a bone cement injector push rod, a bone cement injector sleeve, a bone cement injector puncture sleeve and a puncture needle. The bolus needs to be manually manipulated by the physician during the procedure and the fixation of the cement injector during the bolus is also done manually by the physician. When the doctor carries out bone cement and pushes and inject, the patient still need bear the pressure of whole bone director, and unstable phenomenon can appear, influences pushing of bone cement, has increased the risk of operation. Moreover, when injecting bone cement, doctors are required to perform multiple X-ray irradiation on patients in real time to determine whether the bolus dose and position are accurate. The dosage of the bolus of bone cement and the amount of thrust force and the speed of movement of the push rod of the bone cement injector during the bolus cannot be precisely controlled by the experience of the physician alone.
When bone cement is injected into a diseased vertebral body, a large injection pressure is often present at the injection end, which may result in that the bone cement cannot be injected into a human body. The bone cement is injected when being in a toothpaste shape or a pull wire shape, and the complete solidification needs a certain time, so the state of the bone cement injector and the time for performing the operation need to be accurately controlled, otherwise, the bone cement is solidified before being injected into the pathological vertebral body. And the bone cement is injected into a certain part too much, and can leak out of the vertebral body, so a series of complications are caused, irreparable damage is caused to a patient, and the risk of operation is increased. In addition, because current push injection system bone cement outlet pipe length is limited, the doctor receives a large amount of X ray radiation in the operation in-process of pushing in the ward, even can adopt the guard plate to protect, still has certain potential safety hazard.
