Minimally invasive surgery has revolutionized surgical practice by reducing surgical trauma and enhancing recovery. In this context, the da Vinci SP System represents a major technological advancement. This review aims to report its clinical applications in general surgery, evaluating associated outcomes and potential advantages.
Methods
A systematic search of MEDLINE, Embase and Web-of-Science databases was conducted in accordance with PRISMA guidelines. The study was pre-registered in PROSPERO.
Results
Seventy-six studies involving 1841 patients were included. The most frequently reported procedures were colorectal/transanal surgeries (868) and cholecystectomies (661). Learning-curve analyses for SP colorectal surgery demonstrated performance stabilization after 18–21 cases. Comparative studies showed shorter docking times and reduced hospital stays for SP procedures compared to laparoscopic multiport or single-site robotic approaches.
Conclusion
The da Vinci SP system appears to be a safe and feasible option for various general surgery procedures. Preliminary evidence supports improved perioperative efficiency in specific contexts, though further validation is warranted.

This study compares robotic-assisted pancreatic surgery (R-PS) and laparoscopic pancreatic surgery (L-PS) outcomes in patients with pancreatic malignancies and medium- to high-risk pancreatic fistulas.
Materials and Methods
A retrospective cohort study was conducted at Guangdong Provincial People's Hospital (2021–2023). The primary endpoints were major complications (Clavien-Dindo grade ≥ III) and postoperative morbidity.
Results
200 R-PS and 400 L-PS patients were included, with 163 pairs matched. R-PS showed lower conversion rates (2.5% vs. 17.2%, p < 0.001), less blood loss (119 vs. 179 mL, p = 0.013), and faster function recovery (8.2 vs. 9.6 days, p = 0.038). Postoperatively, R-PS had fewer pancreatic fistulas in malignant (4.1% vs. 32.6%, p < 0.001) and moderate to high-risk cases (8.3% vs. 16.7%, p = 0.026). R-PS benefits are not procedure-specific.
Conclusion
R-PS offers advantages in blood loss, complications, and fistula prevention, suggesting it may be preferable for complex pancreatic surgeries.

Percutaneous abdominal interventions require precise and real-time guidance for safe needle placement. Conventional CT or fluoroscopy provides accurate localisation but involves radiation, while ultrasound (US) offers a radiation-free alternative but suffers from limited 3D visualisation.
Methods
We developed a guidance system integrating a needle-guide mechanism with a tracked US probe to achieve real-time radiation-free targeting. The approach reconstructs freehand 3D US volumes at 25 frames per second, enabling path planning and augmenting the needle trajectory onto live B-scan images. Validation was conducted using a mockup, two phantoms, a pig model, and a human volunteer.
Results
The system completed 3D US acquisition within 10 s and achieved high accuracy, with mean calibration errors of 0.62 mm and 0.22°. Needle tracking yielded angular and positional errors of 0.84 ± 0.40° and 0.76 ± 0.38 mm.
Conclusions
This method enables accurate, rapid, and radiation-free guidance, demonstrating strong potential for clinical application.

This work presents a low-complexity robotic device for needle-to-target alignment designed to streamline Magnetic Resonance Imaging (MRI)-guided biopsy procedures while maintaining physician control over insertion.
Methods
The robotic device was designed with a rigid frame incorporating two linear degrees of freedom for the in-plane alignment of a needle guide with a predefined target. Trajectory planning and automated motion execution, including image transfer and sequence triggering, were managed through a custom MRI-integrated software interface. Preliminary evaluation of alignment accuracy was performed in an agar phantom containing 5 and 10 mm tumour mimics.
Results
In phantom experiments, the system consistently achieved submillimeter alignment accuracy for both the 5-mm and 10-mm tumour models across all trials, without any operational failures.
Conclusions
These preliminary findings demonstrate the feasibility of the proposed robotic device for semiautomated MRI-guided abdominal biopsy, pending further extensive preclinical testing.

Background
The concentric tube robots (CTRs) show great potential for minimally invasive surgery due to their size and flexibility. However, friction remains a key factor contributing to accuracy errors in CTR applications, and reducing friction effects to enhance CTRs' precision remains a critical challenge.
Methods
This paper pioneers the application of a vibration friction reduction (VFR) method for CTRs, aiming to reduce inter-tube friction and improve system accuracy. First, a CTR system with VFR was designed, incorporating a vibration generator consisting of four vibration motors and a 3D-printed component. Then, to better test and analyse the effects of vibration on friction, a variable-friction coefficient kinematic model for CTRs was established. Finally, experiments were conducted to validate the approach.
Results
The results show that the VFR method can reduce the positional error of CTRs by approximately 36.5%.
Conclusion
This paper provides a new approach to enhance CTRs' accuracy in surgical applications.

Background
Interest in robotic colorectal surgery is growing, but outcomes in the Australian public health sector are lacking. This study aimed to evaluate short-term outcomes following robotic colorectal surgery in a public hospital setting.
Methods
This retrospective case series included 70 patients who underwent robotic colorectal surgery and were treated at the Royal Adelaide Hospital, South Australia, between 2015 and 2025. All procedures were performed using the da Vinci Xi Surgical System.
Results
The mean operative time was 270 min, with a 4.3% conversion rate to open surgery. The median length of stay was 5 days and there was no 30-day mortality. R0 resection rates were 93.3% for colon cancer and 87.5% for rectal cancer.
Conclusions
Robotic colorectal surgery can be safely implemented within a universally funded public hospital setting. In our specific centre we demonstrate excellent surgical outcomes but have identified oncological outcomes that need ongoing improvement with increasing volume.

Background
Lymph node dissection is essential for lung cancer staging and treatment planning. This study compares the extent and quality of lymph node dissection between robot-assisted thoracic surgery (RATS) and video-assisted thoracic surgery (VATS).
Methods
In this prospective cohort study, 40 patients undergoing oncologic lobectomy via RATS (n = 20) or VATS (n = 20) were included. We assessed the number of explored lymph node stations, dissected nodes, and microscopic integrity criteria.
Results
RATS resulted in a higher median number of explored stations (5 vs. 4; p = 0.0375) and resected nodes (8 vs. 6; p = 0.0432). However, no significant differences were found in the microscopic quality criteria.
Conclusions
RATS enables broader lymph node dissection but does not improve microscopic quality compared with VATS. These findings highlight the need for further studies to assess clinical outcomes.

Surface electromyography (sEMG) enables gesture recognition for rehabilitation and human-computer interaction but faces challenges from noise, inter-subject variability, and limited motion dynamics characterisation.
Methods
We propose BSCAL, a dual-stream network integrating sEMG and inertial measurement unit (IMU) signals. The architecture combines convolutional neural networks (CNNs), long short-term memory (LSTM) networks, and spatiotemporal attention to process eight-channel sEMG and six-channel IMU data from 20 participants performing six gestures. Kalman filtering, Z-score normalisation, and gated fusion optimise multimodal feature integration.
Results
BSCAL achieved 90.41% ± 1.54% recognition accuracy, surpassing single-modality models and state-of-the-art approaches. Ablation studies validated contributions from CNN (local features), LSTM (temporal dependencies), and attention (key feature enhancement).
Conclusions
By synergistically integrating neuromuscular patterns from EMG and kinematic data from IMU, BSCAL delivers a precise and scalable solution for gesture recognition, thereby advancing the development of wearable hand rehabilitation robots and assistive technologies for motor function recovery.

Near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) has been recently introduced for lymphatic mapping in robotic gastrectomy.
Methods
Sixty-two patients with early gastric cancer (EGC) were divided into three groups, namely ICG-guided robotic group (G1; n = 18), conventional robotic group (G2; n = 24), and laparoscopic control group (control; n = 20). The primary endpoints were retrieved LNs, surgical outcomes, and postoperative complications.
Results
The G1 group retrieved more total LNs than the other two groups; however, this difference was not statistically significant (19.8 vs. 16.1 vs. 16.9, p = 0.197). However, there were statistical differences in perigastric LNs (15 vs. 10.5 vs. 11, p = 0.010). The G1 group had shorter surgical time than G2 (260 vs. 300 min, p < 0.05).
Conclusion
ICG guided technology aids in achieving a more precise regional LN dissection during robotic gastrectomy for EGC, and is a valuable advancement for gastric cancer surgery.

近红外（NIR）荧光成像与吲哚菁绿（ICG）最近被引入到机器人胃切除术的淋巴定位。方法将62例早期胃癌（EGC）患者分为ig引导机器人组（G1组，n = 18）、常规机器人组（G2组，n = 24）和腹腔镜对照组（对照组，n = 20）。主要终点为检索LNs、手术结果和术后并发症。结果G1组总回收量高于其他两组；然而，这一差异无统计学意义（19.8比16.1比16.9,p = 0.197）。然而，胃周ln有统计学差异（15 vs. 10.5 vs. 11, p = 0.010）。G1组手术时间短于G2组（260 vs 300 min, p < 0.05）。结论在机器人胃切除术中，ICG引导技术有助于实现更精确的区域淋巴结清扫，是胃癌手术的重要进展。中国临床试验注册中心（ChiCTR2500106082）

Minimally invasive anatomic lung resections are the standard for early non-small-cell lung cancer, and the robotic approach has gained popularity and the latest frontier is the uniportal robotic (uRATS) approach. The goal of our study is to share our series showing technical details, feasibility and early outcomes.
Methods
From December 2024, we started the uRATS programme for selected patients. Continuous and dichotomous variables were recorded about surgery and the perioperative period. Non-parametric tests were used to compare the data between uRATS and contemporary patients treated with robotic multiport RATS.
Results
In 4 months we performed two segmentectomies and five Lobectomy through uRATS, while one patient was converted due to incomplete fissure. No severe perioperative complications occurred and in the comparison with the multiport approach, no significant differences in operative time, conversions and complications were observed.
Conclusions
The Uniportal RATS approach was safe and feasible with adequate surgical and oncologic post-operative results.
