“…There were no statistically significant differences between the 2 groups in gender, age, cause of injury, fracture lateral, fracture type and time from injury to surgery ( P > .05). There were 4 retrospective case–control studies [ 1 , 2 , 13 , 21 ] and 1 prospective study [ 11 ] that compared a series of patients. Four studies used the bi-planar robot system (TINAV/TiRobot Medical Technologies, China) [ 1 , 2 , 11 , 21 ] and 1 used the UR Positioning Robots (Universal Robots, Denmark).…”

“…Three studies failed to report the random sequence generation and allocation concealment. [ 1 , 13 , 21 ] Blinding of patients and personnel was unfeasible to surgeons in the included studies and the risk of bias was judged high. The outcome assessments were reported in all articles and they were judged to low risk of bias.…”

“…[ 1 ] Due to high-energy trauma, young adults are also likely to suffer femoral neck fractures, yet only accounting 2% to 3%. [ 1 , 2 ] Surgery was increasingly advocated in most femoral neck fractures, including: in situ fixation, closed or open reduction and internal fixation, hemiarthroplasty, and total hip arthroplasty. [ 3 ] The Garden classification was selected to guide the surgical method for the femoral neck fractures and was commonly divided into 4 types.…”

Background: Several studies have reported that medical robot-assisted method (RA) might be superior to conventional freehand method (FH) in orthopedic surgery. Yet the results are still controversial, especially in terms of femoral neck fractures surgery. Here, 2 methods were assessed based on current evidence. Methods: Electronic databases including Cochrane Library, PubMed, Web of Science. and EMBASE were selected to retrieved to identify eligible studies between freehand and RAs in femoral neck fractures, with 2 reviewers independently reviewing included studies as well as collecting data. Results: A total of 5 studies with 331 patients were included. Results indicated that 2 surgical methods were equivalent in terms of surgical duration, Harris score, fracture healing time, fracture healing proportion and complications, while RA showed clinical benefits in radiation exposure, intraoperative bleeding, total drilling times, and screw parallelism. Conclusions: Current literature revealed significantly difference between 2 techniques and suggested that RA might be beneficial for patients than freehand method.

“…Compared with previous methods, the surgery is more convenient, the design is more reasonable, and the damage to the patient’s body is less, thus, the procedure is more suitable for elderly patients with poor recovery ability. 26 , 27 PFNA is a relatively new type of proximal femoral nail for PFN internal fixation that involves a spiral blade. The effect of inserting two screws in the internal fixation method is the same, but PFNA greatly shortens the duration of surgery, makes the surgery easier, and patients have fewer complications following surgery.…”

Objective To investigate the effect of angler-assisted proximal femoral nail antirotation (PFNA) spiral blade fixation in treating femoral trochanteric fractures. Methods Patients who underwent angler-assisted PFNA screw blade fixation (angler-assisted group), or conventional internal fixation-intramedullary nailing (traditional surgery group) were included. Intraoperative indicators and treatment effects data were retrospectively analysed. Results Statistically significant differences were observed between the angler-assisted group ( n = 27) and traditional surgery group ( n = 28) regarding surgery duration (71.24 ± 8.01 min versus 81.50 ± 11.56 min), number of intraoperative fluoroscopy images (7.28 ± 0.91 versus 12.83 ± 1.55), and surgical bleeding volume (88.80 ± 7.98 ml versus 121.11 ± 27.21 ml). Rates of one-time intramedullary pin puncture for internal fixation in the angler-assisted and traditional surgery groups were 92.59% (25/27) and 32.14% (9/28), respectively. At 1 year following surgery, fractures in both groups had healed without internal fixation failure or fracture displacement failure. Harris hip function scores were 90.68 ± 4.23 (angler-assisted group) versus 81.69 ± 5.85 (traditional surgery group). Conclusions Angler-assisted intramedullary nailing with PFNA spiral blade provides good spiral blade positioning, low internal fixation failure rate, low fluoroscopy, short surgery time, and low bleeding volume. Hip function was well restored.

“…The PID parameters are set by Zeigler Nichols and genetic algorithm, and the tracking effect is significantly improved compared with the traditional PID. To solve the problem of high-precision trajectory tracking of double-link robots under model uncertainty and external disturbances, relevant scholars have designed a sliding mode control strategy that includes fuzzy tuning PID sliding mode surfaces [28]. This method combines fuzzy gain tuning, the robustness of the sliding mode controller and the rapid response characteristics of the PID, which effectively reduces the chattering caused by the sliding mode controller and improves the stability of the system.…”

Minimally invasive surgical robots have received more and more attention from medical patients because of their higher surgical accuracy and higher safety than doctors. Minimally invasive surgery is rapidly revolutionizing the treatment of traditional surgery. In order to solve the problem that the surgical robot has a redundant degree of freedom, which makes the kinematics solution more complicated, this paper analyzes the kinematics of the coordinate system block. Aiming at the problem that the strategy search algorithm needs to re-learn when the target pose changes, a convolutional neural network control strategy is studied and constructed. By designing the structure of the convolutional neural network visual layer and motor control layer, the loss function and sampling of the training process are established. Aiming at the problem of long training time of convolutional neural network, an effective pre-training method is proposed to shorten the training time of the neural network. At the same time, the effectiveness of the above method and the end-to-end control of the convolutional neural network strategy are verified through simulation experiments. The physical structure of the manipulator body is analyzed, and the forward and inverse kinematic equations of the manipulator are established by the D-H method. Monte Carlo method was used to analyze the working space of the manipulator, and low-latency control and simulation experiments were carried out on the movement trajectory of the manipulator in joint space and Cartesian space. The results show that the low-latency control algorithm in this paper is effective to control the mechanical arm of the minimally invasive medical surgery robot. INDEX TERMS Invasive medical surgical robot, kinematics analysis, convolutional neural network, low trajectory control.
