Description

Technical Field

[0001] The present invention relates to the technical field of bone cement injection, and in particular to a bone cement remote injection device capable of quickly replacing multiple types of syringes. Background Art

[0002] Vertebroplasty is currently the most effective treatment for osteoporotic vertebral compression fracture (OVCF) in clinical practice, including percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP). It is widely used in clinical practice because of its advantages of less trauma, faster recovery, significant pain relief, and effective avoidance of complications caused by long-term bed rest. However, the most common complication of vertebroplasty is the leakage of bone cement. If bone cement leaks into the spinal canal, it will compress the spinal cord and nerves, causing catastrophic consequences, and even paralysis in severe cases. Therefore, in order to effectively avoid the leakage of bone cement and to observe the penetration state and range of bone cement in the vertebral body in time during vertebroplasty, spinal surgeons need to inject bone cement into the vertebral body under X-ray fluoroscopy. Doctors suffer huge radiation damage, and the risk of cancer is significantly increased, which seriously endangers the health of spinal surgeons. In addition, for patients who need to inject bone cement into multiple sections of the spine, the amount of bone cement required is large. Currently, more than a dozen hollow thin steel tube fillers for manual bone cement injection need to be replaced for each operation, which makes the doctor's operation too cumbersome. In vertebroplasty, how to check the penetration status of bone cement in a timely manner without being exposed to radiation has become one of the problems that urgently need to be solved in medicine and mechanical engineering. The present invention designs and develops a remote-controlled bone cement injection device that can be away from radiation and control the injection of bone cement by remote control. This not only avoids radiation damage to doctors, but also allows timely observation of the penetration status and penetration range of bone cement to avoid leakage of bone cement and ensure the safety of the operation.

[0091] Step 2: insert the puncture needle 3 into the designated injection position of the body.

[0092] Step 3: Install the base 6 with the bracket 5 on the side bracket of the standard operating table, and then install the syringe body 4 on the bracket 5.

[0093] Step 4: Use the connecting hose 2 to connect the medical syringe 1 and the puncture needle 3 to establish a working channel.

[0094] Step 5, the push rod 46 of the syringe body 4 is fed forward. When the proximity switch 44 approaches the metal disc on the tail clamping slider 43, the proximity switch 44 generates a signal, the push rod 46 stops moving, and then moves forward 3mm, so that the push rod 46 is close to the rear of the tail clamping slider 43.

[0095] Step 6: The remote wired (wireless) controller starts to control the feed amount (injection amount) of the push rod 46.

[0096] Step 7: After the injection is completed, the puncture needle 3 is pulled out from the body, and then the medical syringe 1, the connecting hose 2 and the puncture needle 3 are removed from the syringe body 4 as a whole, and finally the base 6 is removed from the standard operating table to complete the injection work.

[0097] During bone cement injection surgery (vertebroplasty), remote operation is possible.

[0098] 2. Steps for using the quick-change syringe:

[0102] Step 3: then flip over the clamping cover 4121 and transfer the clamping cover 4121 to the upper surface of the medical syringe 1 .

[0103] Step 4: Finally, flip the locking block 4125 and buckle the locking block 4125 into the raised portion of the clamping cover 4121 to complete the locking.

[0104] Taking out the syringe process:

[0105] Step 1: First, flip the locking block 4125, flip the locking block 4125 out of the raised part of the clamping cover 4121, and unlock it.

[0106] Step 2: then flip the clamping cover 4121 over to flip the clamping cover 4121 away from the upper surface of the medical syringe 1.

[0107] Step 3: When working, take out the main body of the medical syringe 1 filled with bone cement and waiting for injection of medicine from the quick-release base 4124.

[0108] Step 4: Take the bottom of the inner tube of the used medical syringe 1 upward from the designated position of the tail clamping slider 43 to complete the overall separation.

[0109] 3. Steps for using the quick-change syringe fixture:

[0110] Step 1: When replacing the clamp, make sure the syringe has been removed from the clamp.

[0111] Step 2: Use the thumbs of both hands to press the two hinges 4122 on the quick-release syringe clamp 412 connected to the clamping cover 4121, and push the quick-release syringe clamp 412 from the hinge 4122 to the hinge 4123. A "click" sound can be heard during the pushing process.

[0112] Step 3: After pushing out, align the dovetail groove 4126 of the new fixture with the dovetail 42 of the quick-release fixture, and push the quick-release syringe fixture 412 from the hinge 4123 to the hinge 4122. A "click" sound can be heard during the pushing process, and it is pushed to the specified position.

[0113] Step 4. After installing the new fixture, install the new syringe according to "II. Quick-change syringe usage steps".
