Background
Intraoperative cone‐beam computed tomography (CBCT) offers the advantage of navigation on the current anatomical situation and the possibility to take a control scan. We assessed the feasibility of using intraoperative CBCT for navigated intralesional curettage.
Methods
Nine benign bone tumour patients were studied. Feasibility was assessed by describing the workflow and indications...
Background
Transhumeral prostheses are worn by transhumeral amputees to replace the missing upper limb segment between shoulder and elbow. Prostheses should be able to function as a natural limb for the user to gain the full advantage of wearing a prosthesis. When performing reach‐to‐grasp and pointing motions by the upper limb, the hand is capable of adhering to a straight‐line path with a bell‐shaped...
Background
Keyhole surgery is characterized by loss of dexterity of surgeon's movements because of the limited workspace, nonintuitive motor skills of the surgical systems, and loss of tactile sensation that may lead to tissue damage and bad execution of the tasks.
Methods
In this paper, a three‐fingered underactuated miniature tool for robot‐aided laparoscopic surgery is presented. The design...
Background
Several studies have compared robotics‐assisted (RA) and conventional manual (CM) approaches for total hip arthroplasty (THA), but their results are controversial.
Methods
A literature search was conducted for controlled clinical trials (CCTs) comparing the clinical efficacy of the RA and CM approaches for THA and published between August 1998 and August 2018. The obtained data were...
Background
Conventional video‐assisted minimally invasive esophagectomy (MIE) is safe and associated with low rates of morbidity and mortality, but the two‐dimensional monitor reduces eye‐hand harmony and viewing yield. Robotic‐assisted minimally invasive esophagectomy (RAMIE) with its virtual reality simulators offers a realistic three‐dimensional environment that facilitates dissection in the narrow...
Background
The adoption of minimally invasive surgery for transduodenal ampullectomy has been slow because of special characteristics and complexity of this procedure.
Methods
Six patients underwent robotic transduodenal ampullectomy. We employed novel methods to facilitate exposure of the ampulla.
Results
All patients completed robotic transduodenal ampullectomy, but one patient was immediately...
Background
Rigid image coregistration is an established technique that allows spatial aligning. However, rigid fusion is prone to deformation of the imaged anatomies. In this work, a novel fully automated elastic image registration method is evaluated.
Methods
Cervical CT and MRI data of 10 patients were evaluated. The MRI was acquired with the patient in neutral, flexed, and rotated head position...
Background
Bile duct injury after cholecystectomy can be a life‐threatening complication. Use of robotic approach to manage a complex biliary injury is in an early phase.
Methods
We have performed an analysis of our prospectively maintained database that included 12 patients who underwent robotic‐assisted repair of bile duct injury after laparoscopic cholecystectomy between 2014 and 2017.
Results...
Recently, minimally invasive surgery (MIS) robotics enters the phase of autonomous operation. However, because of the high variability of the environment, conducting a fully autonomous surgery is still extremely difficult. This paper presents a share control system, the objective of which is to suggest the optimum path of tool guidance through the use of force on the master manipulator (hereinafter...
Background
This paper presents a model‐based bone milling state identification method that provides intraoperative bone quality information during robotic bone milling. The method helps surgeons identify bone layer transitions during bone milling.
Methods
On the basis of a series of bone milling experiments with commercial artificial bones, an artificial neural network force model is developed...
Background: In robot‐assisted minimally invasive surgery, feedback as well as sensing of translational and grasping forces allows surgeons to manipulate the robots using an appropriate force. However, there have been limited reports on single instruments capable of sensing both forces (translational force and grasping force), with the exception of instruments with electronic sensors.
Methods: In this...
Background
When fashioning a retrosigmoid craniotomy, precise placement of the initial burr hole is crucial to avoid iatrogenic sinusal injury and to facilitate a corridor that allows for minimal cerebellar retraction.
Methods
3D CT reconstructions of 16 cadaveric sides were used to identify and measure three discrete anatomical points. These three points and distances between them were plotted...
