Background
Microsurgery is generally performed in narrow spaces with limited movement. Endoscopes that allow for angle changes have been developed using elastic materials, but they require a large bending space. We propose a new endoscope with a small sweep volume for angle changes.
Methods
We fabricated a prototype with a thumb‐operated joystick. The image sensor is attached to the tooltip. The...
Background
Oesophageal benign to borderline tumours are rare entities, and their optimal treatment strategy remains controversial. Surgical robotic enucleation is an option to optimize their management.
Methods
We prospectively collected data on seven consecutive oesophageal benign to borderline tumours operated robotically over a 4‐year period. Patient baseline characteristics, perioperative outcomes...
Background
Sutures are a set of standard actions which are accomplished by multi‐instruments, researchers studied the robot autonomy of suturing, which was based on movement planning completed by a single instrument, but did not consider the assignment of suturing tasks to instruments.
Method
A method was proposed for the autonomous suturing task assignment to instruments, which built a comprehensive...
Purpose
Both safety and accuracy are of vital importance for surgical operation procedures. An efficient way to avoid the singularity of the surgical robot concerning safety issues is to maximize its manipulability in robot‐assisted surgery. The goal of this work was to validate a dynamic neural network optimization method for manipulability optimization control of a 7‐degree of freedom (DoF) robot...
Aim
Transrectal ultrasound (TRUS) guided prostate biopsy is a typical early prostate examination. However, the ultrasound imaging suffers from blurred contour, intensity inhomogeneity and small surrounding soft tissue differentiation. To take advantage of clear magnetic resonance imaging (MRI) into robotic prostate biopsy navigation, the prostate regions in the MRI and TRUS images need to be segmented...
Background
This study presents user evaluation studies to assess the effect of information rendered by an interventional planning software on the operator's ability to plan transrectal magnetic resonance (MR)‐guided prostate biopsies using actuated robotic manipulators.
Methods
An intervention planning software was developed based on the clinical workflow followed for MR‐guided transrectal prostate...
Background
Holding endoscopes by hand when performing eye surgery reduces the dexterity of the surgeon.
Methods
A robotic endoscope holder called “Eye Explorer” is proposed to hold the endoscope and free the surgeon's hand.
Results
This device satisfies the engineering and clinical requirements of eye surgery. The force for manual operation is less than 0.5 N. The observable ranges inside the...
Background
Interventional robots currently exist for flexible ureteroscopy (fURS). However, force feedback and intra‐renal pressure, which are important in fURS, were rarely considered when designing these robots.
Methods
We propose a novel robotic system for fURS integrated with partial force feedback function that is the bending knob's torque feedback of the flexible ureteroscope, and intra‐renal...
Background
Traditional flexible endoscopes are sophisticated medical devices that require frequent and expensive maintenance. Therefore, their implementation within low‐income and rural regions is challenging due to their high cost, complex sterilization process and poor portability.
Aims
This paper aims to develop an endoscopic platform that is low‐cost, disposable and portable, with the primary...
Background
Existing surgical navigation approaches of the rod bending procedure in spinal fusion rely on optical tracking systems that determine the location of placed pedicle screws using a hand‐held marker.
Methods
We propose a novel, marker‐less surgical navigation proof‐of‐concept to bending rod implants. Our method combines augmented reality with on‐device machine learning to generate and...
Background
This systematic review sought to compare the urogenital functions after laparoscopic (LAP) and robotic (ROB) surgery for rectal cancer.
Methods
This study conformed to the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines.
Results
Twenty‐six studies (n = 2709 for ROB, n = 2720 for LAP) were included. There was a lower risk of 30‐day urinary retention in...
Background
Cystoscopy plays an important role in the diagnosis of bladder tumours. As a typical representative of the deep learning algorithm, the convolutional neural network has shown great advantages in the field of image recognition and segmentation.
Methods
One thousand two photographs of normal bladder tissue and 734 photos of bladder tumours under cystoscopy were taken from 175 patients...
Background
Most comparisons between robot‐assisted partial nephrectomy (RAPN) and open partial nephrectomy (OPN) indicate the superiority of RAPN, but the learning curve is often not considered.
Methods
All consecutive partial nephrectomies from the very first RAPN at a single tertiary referral centre (n = 818, 500 RAPN vs. 313 OPN) were retrospectively analyzed. Complications, success rates and...
Background
Traditional fracture reduction surgery cannot ensure the accuracy of the reduction while consuming the physical strength of the surgeon. Although monitoring the fracture reduction process through radiography can improve the accuracy of the reduction, it will bring radiation harm to both patients and surgeons.
Methods
We proposed a novel fracture reduction solution that parallel robot...
Background
The robotic‐assisted unicompartmental knee arthroplasty (UKA) is proposed to improve the accuracy of component positioning.
Methods
We conducted a literature search in Medline, Embase, Web of Science and the Cochrane Library until April 2020.
Results
Our meta‐analysis included 10 articles, involving 1231 knees. Our meta‐analysis demonstrated that the robotic group had significantly...
Background
Magnetic technologies have been introduced to reduce invasiveness of surgical procedures. This study was aimed to analyse the performance of a novel combined magnetic‐robotic controller as an enhanced accessory to the Magnetic Surgical System in laparoscopic cholecystectomy (LC).
Methods
This was a prospective study of 10 consecutive patients undergoing LC with this novel surgical system...
Background
Some difficulties are common when using endoscopes. Steering is not intuitive, the endoscope weight is a physical burden to physicians and communication problems often occur between operators.
Method
To overcome these, we developed a robotic endoscopy system and conducted a usability test to compare conventional and robotic manipulation. Nine novices and eighteen physicians participated...
Background
The distribution, utilisation and accessibility of surgical robotics in England is unknown.

A nationwide Freedom of Information (FOI) request was sent to all acute National Health Service (NHS) trusts. Accessibility was assessed for 32 843 Lower Super Output Areas in England.
Results
All 149 acute NHS trusts responded to the FOI request. Sixty‐one robots are distributed between...
Synopsis
Standardization of robotic oesophagectomy can benefit both patients and surgeons by decreasing complications, shortening the learning curve and improving surgical training.

Thoraco‐abdominal oesophagectomy with lymphadenectomy is the cornerstone of curative therapy for oesophageal carcinoma. To reduce post‐operative morbidity, minimally invasive technology has become increasingly...
Background
Recently, task‐autonomous image‐guided robotic cochlear implantation has been successfully completed in patients. However, no data exist on patients' perspective of this new technology.
