Background
A method for the identification of semi‐active fiducial magnetic resonance (MR) markers is presented based on selectively optically tuning and detuning them.Methods
Four inductively coupled solenoid coils with photoresistors were connected to light sources. A microcontroller timed the optical tuning/detuning of coils and image collection. The markers were tested on an MR manipulator linking the microcontroller to the manipulator control to visibly select the marker subset according to the actuated joint.Results
In closed‐loop control, the average and maximum were 0.76° ± 0.41° and 1.18° errors for a rotational joint, and 0.87 mm ± 0.26 mm and 1.13 mm for the prismatic joint.Conclusions
This technique is suitable for MR‐compatible actuated devices that use semi‐active MR‐compatible markers. 相似文献2.

Background
Transoral robotic surgery (TORS) using the Single-Port system (SPS) relies on electrocautery, limiting its applications in the upper aerodigestive tract. We evaluated the feasibility of a CO2 delivery system for the SPS.Methods
Otolaryngology residents performed a cutting exercise using a handheld CO2 laser and participated in a cadaveric oropharyngeal dissection using the SPS with monopolar cautery (SP + EC) and CO2 laser (SP + CO2). Residents completed the System Usability Scale (SUS) questionnaire to evaluate these techniques.Results
The same laser fiber was used for all combined dissections. The handheld CO2 laser, SP + EC, and SP + CO2 demonstrated similar SUS scores. On individual domain scores, SP + CO2 received less favorable ratings compared to the handheld CO2 laser for complexity, integration, and cumbersome experience (p < 0.05). On subgroup stratification, less TORS experience was associated with worse SUS scores.Conclusion
SP-guided CO2 laser delivery is a viable alternative to electrocautery in robotic surgery, and should be considered when performing TORS. 相似文献3.

Introduction
As robotic surgery increases its reach, novel platforms are being released. We present the first 17 consecutive cases of alimentary tract surgery performed with the HugoTM RAS (Medtronic).Methods
patients were selected to undergo surgery from February through April 2023. Exclusion criteria were age <16 years, BMI>60, ASA IV.Results
17 patients underwent ileocaecal resection for Chrons disease (2 M and 1 F) and pseudo-obstruction of the terminal ileum (1 M), cholecystectomy (3 M and 5 F), subtotal gastrectomy with D2 lymphadenectomy (1 F), sleeve gastrectomy (1 F), hiatal hernia repair with Nissen fundoplication (1 M), right hemicolectomy (1 M) and sigmoidectomy (1 M). No conversion to an open approach or any arm collisions requiring corrective actions were reported.Conclusions
Our preliminary experience with the HugoTM RAS point to safety and feasibility for a rather wide spectrum of surgical procedures of the alimentary tract. 相似文献5.

Background
We aimed to evaluate the accuracy and safety of a novel self-tapping bone fiducial as a registration technique for stereoelectroencephalography (SEEG) implantation.Methods
Each patient was installed with five bone fiducial markers. All procedures were performed using the same Sinovation robot system. The accuracy was determined by calculating the target point error (TPE) and the entry point error (EPE) of electrodes.Results
Fourteen patients underwent SEEG implantation surgery; and the average installation time of the markers per patient was 86.1 s. In the operating theatre, the average registration time was 206.6 s, and the average registration error was 0.18 mm. The average TPE of 174 electrodes was 1.98 mm and the average EPE was 0.88 mm.Conclusion
Our study provided a bone fiducial marker installation and registration technique that was convenient and fast, highly accurate in registration, and highly tolerated by patients. 相似文献10.

Background
Impairment of haptic perception by surgical gloves could reduce requirements on haptic systems for surgery. While grip forces and manipulation capabilities were not impaired in previous studies, no data is available for perception thresholds.Methods
Absolute and differential thresholds (20 dB above threshold) of 24 subjects were measured for frequencies of 25 and 250 Hz with a Ψ‐method. Effects of wearing a surgical glove, moisture on the contact surface and subject's experience with gloves were incorporated in a full‐factorial experimental design.Results
Absolute thresholds of 12.8 dB and ?29.6 dB (means for 25 and 250 Hz, respectively) and differential thresholds of ?12.6 dB and ?9.5 dB agree with previous studies. A relevant effect of the frequency on absolute thresholds was found. Comparisons of glove‐ and no‐glove‐conditions did not reveal a significant mean difference.Conclusions
Wearing a single surgical glove does not affect absolute and differential haptic perception thresholds. 相似文献11.

Background
Critically ill pediatric patients can have difficulty with establishing and maintaining stable vascular access. A long-dwelling peripheral intravenous catheter placement decreases the need for additional vascular interventions.Aim
The study sought to compare longevity, catheter-associated complications, and the need for additional vascular interventions when using ultrasound-guided longer peripheral intravenous catheters comparing to a traditional approach using standard-sized peripheral intravenous catheters in pediatric critically ill patients with difficult vascular access.Methods
This single-center retrospective cohort study included children 0–18 years of age with difficult vascular access admitted to the pediatric intensive care unit between 01/01/2018–06/01/2021.Results
One hundred and eighty seven placements were included in the study, with 99 ultrasound-guided long intravenous catheters placed and 88 traditionally placed standard-sized intravenous catheters. In the univariate analysis, patients in the traditional approach were at a higher risk of intravenous failure compared to those in the ultrasound-guided approach (HR = 2.20, 95% CI [1.45–3.34], p = .001), with median intravenous survival times of 108 and 219 h, respectively. Adjusting for age, patients in the traditional approach remained at higher risk of intravenous failure (HR = 1.99, 95% CI: [1.28–3.08], p = .002). Adjusting for hospital length of stay, patients in the ultrasound-guided approach were less likely to have additional peripheral intravenous access placed during hospitalization (OR = 0.39, 95% CI [0.18–0.85] p = .017).Conclusion
In critically ill pediatric patients with difficult vascular access, ultrasound-guided long peripheral intravenous catheters provide an alternative to traditional approach standard-sized intravenous catheters with improved longevity, lower failure rates, and reduced need for additional vascular interventions. 相似文献12.
