What is stereotactic surgery
Stereotactic Surgery is a minimally invasive surgical technique that uses a three-dimensional coordinate system to accurately locate lesions in the brain or other body parts. It uses imaging guidance (such as MRI, CT) and computer-aided navigation to achieve precise positioning and operation of lesions, and is widely used in neurosurgery, tumor treatment and other fields. The following is a compilation of hot topics related to stereotaxic surgery in the hot topics on the Internet in the past 10 days.
1. Core features of stereotaxic surgery
| Features | illustrate |
|---|---|
| Accuracy | The error range can be controlled within 1 mm |
| Minimally invasive | Only a small incision or puncture is required |
| Wide range of indications | Suitable for tumors, epilepsy, Parkinson's disease, etc. |
2. Popular medical technology developments in the past 10 days
| time | event | Related technologies |
|---|---|---|
| 2023-11-05 | AI-assisted stereotactic surgical robot approved | Artificial intelligence + robotic arm |
| 2023-11-08 | Clinical breakthrough in frameless stereotaxic system | Optical navigation technology |
| 2023-11-12 | The world's first 5G remote stereotactic surgery completed | Telemedicine |
3. Main application fields of stereotaxic surgery
1.neurosurgery: Treatment of brain tumors, epilepsy lesions, Parkinson's disease deep brain stimulation (DBS) implantation, etc.
2.radiation therapy: Precision radiosurgery technologies such as Gamma Knife and Cyber Knife.
3.mental illness: Targeted therapy for treatment-resistant depression.
4.biopsy sampling: Precise needle biopsy of tiny lesions.
4. Comparison of surgical procedures (traditional vs stereotactic)
| project | traditional surgery | stereotactic surgery |
|---|---|---|
| Incision size | 5-10cm | 2-5mm |
| length of stay | 5-7 days | 1-2 days |
| Positioning method | naked eye observation | image navigation |
5. Answers to Frequently Asked Questions by Patients
Q: Is stereotactic surgery safe?
A: The complication rate is less than 3%, but the indications need to be strictly evaluated.
Q: Does the surgery require general anesthesia?
A: In most cases, local anesthesia can be done.
Q: How long is the recovery period after surgery?
A: It usually takes 24-48 hours to resume basic activities.
6. Technology development trends
