Technical Field

[0001] This utility model relates to the field of surgical thruster technology, specifically to an orthopedic screw laparoscopic surgical thruster. Background Technology

[0002] In the field of minimally invasive surgery, the application of laparoscopic techniques is gradually becoming a mainstream direction in medical development. Compared with traditional surgical methods, this technique has significant advantages, such as reducing patient trauma, shortening hospital stays, alleviating postoperative pain, accelerating recovery and work capacity, and reducing aesthetic scarring. Especially in orthopedic surgery, the application of laparoscopic techniques is becoming increasingly widespread, as it can assist doctors in more accurately observing lesions or injuries, improving the precision and safety of the surgery.

[0003] However, in actual surgical procedures, when surgeons need to implant internal fixation screws, they often need to enlarge the existing laparoscopic puncture incision to allow for more accurate positioning and manipulation. Although screws can sometimes be implanted directly through the laparoscopic puncture incision to reduce patient trauma, there is currently a lack of effective auxiliary tools to achieve this process.
