Gelatin and food-based ultrasound FNA biopsy phantoms

A set of low-cost phantoms for practising ultrasound-guided fine-needle aspiration biopsy, compared head to head for haptic properties, echogenicity and teaching utility. Nine cytopathologists and cytopathology fellows rated them on a five-point scale. The gelatin phantom at a gelatin to water ratio of 1:8 by weight scored best, followed by the 1:10 gelatin phantom, with tofu and chicken breast also rated as good alternatives needing only a few minutes of preparation.

Silicone small bowel simulator from a 3D-printed mould

An affordable silicone small bowel model cast from a 3D printed mould, for practising the hand-sewn bowel anastomosis outside the operating theatre. In a single-blinded pilot randomised controlled trial, sixteen junior surgical residents took a pretest on the simulator, after which the experimental group practised at home over eight sessions while the control group had no hands-on practice. Posttests used the same simulator and a retention-transfer test was performed on an anaesthetised porcine model, with all attempts filmed and graded by a blinded evaluator.

Haemorrhage-control task simulator for bleeding management

A low cost task simulator for haemorrhage control, used inside a high-fidelity simulation scenario so learners practise stopping exsanguinating bleeding under realistic conditions. Performance was measured by millilitres of blood lost and time taken to control the bleed, alongside the Stop the Bleed Education Assessment Tool and a self-efficacy scale. One hundred and three final-year nursing students took part in a before-after study with follow-up at three months.

Artificial circulatory system for ECMO cannulation simulation

A simulated human circulatory system designed for extracorporeal membrane oxygenation training, developed in collaboration with Hamad Medical Corporation in Qatar. It targets cannulation, the insertion of a cannula into the blood vessels to reroute blood flow to the machine rather than the lung or heart, which is the entry step of the procedure. The rationale given is that ECMO teams must monitor over fifty variables and intervene rapidly, so hands-on simulation lets practitioners build those skills without exposing patients to undue risk.

Artificial circulatory system for ECMO cannulation simulation

A simulated human circulatory system designed for extracorporeal membrane oxygenation training, developed in collaboration with Hamad Medical Corporation in Qatar. It targets cannulation, the insertion of a cannula into the blood vessels to reroute blood flow to the machine rather than the lung or heart, which is the entry step of the procedure. The rationale given is that ECMO teams must monitor over fifty variables and intervene rapidly, so hands-on simulation lets practitioners build those skills without exposing patients to undue risk.

A modular low cost simulator for endolaryngeal microsurgery made of two parts, a laryngeal specimen fixation unit and a flexible laryngoscope holder. It takes porcine larynges and allows adjustable exposure and instrument manipulation under microscopic or exoscopic visualisation, supporting subepithelial vocal fold dissection, microsuturing and CO2 laser cordectomy. Twenty one junior and senior otolaryngologists completed standardised tasks and rated realism, usability and educational value, with mean Likert scores between 4.29 and 4.95 and highest ratings for hand-eye coordination and bimanual dexterity.

3D-printed midface model for nasal osteotomy

A midface model printed in polylactic acid on a desktop 3D printer, derived from a 3D reconstruction modified in the free open-source software Meshmixer, with the pyriform aperture smoothed and support rods added to hold the bone fragments generated during simulation. It lets trainees practise nasal osteotomy, a procedure that is hard to teach because it depends on nuanced tactile feedback and usually relies on costly cadaveric bone. Several infill densities were printed to find the one that best mimicked human facial bone, and an osteotomy was successfully simulated on the model.

SLA 3D-printed metacarpal fracture fixation model

An SLA 3D-printed metacarpal for hand trauma training, designed with cortico-medullary differentiation so that drilling reproduces the tactile feedback of real bone. It is intended for practising hand fracture fixation. Seventeen hand surgeons across three centres tested it and rated it highly, with the model outperforming homogenous control simulators. Used models are returned to a plastic upcycling partner, and the authors plan to add built-in fractures and a soft tissue envelope.

  • Appraised against the CASP systematic review checklist, the one study type in this library it genuinely fits.
  • Strength, the largest evidence base of any entry here, spanning both validity and skills transfer.
  • Limitation, the review itself finds no consensus on which exercises or metrics work best, and reports no clear evidence that simulator skill transfers to patient outcomes.
Kirkpatrick levelLevel 2 to 3 across the included studies, learning is well evidenced, behaviour transfer to real robotic cases is not.

The best evidenced entry in the whole library by volume of studies, and an honest one, it concludes simulators are realistic and useful for training but that nobody has yet shown the skill reliably transfers to patients.

Porcine liver metastases model for robotic resection

A liver metastases model made from the livers of adult Landrace pigs, with porcine perinephric fat used to simulate subcapsular metastases. It is intended for practising robotic parenchyma-preserving liver resection, a technique with a demanding learning curve. Surgical trainees used it in a session supervised by expert robotic surgeons and rated fidelity, tissue handling and overall usefulness highly, suggesting simulated blood as an improvement.

Virtual trainer for ultrasound-guided renal biopsy

KBVTrainer is a virtual simulator for ultrasound-guided renal biopsy built from low-cost hardware components and open source software libraries. It uses real ultrasound images to train needle visualisation, tracking, steadiness and hand-eye coordination. Five expert nephrologists and radiologists rated it in a face validation study, scoring it above 4.4 on most items but only 2.4 for the look and feel of the probe and needle compared with clinical practice.

Swine vas deferens vasectomy reversal model

Swine testicles, normally discarded at markets, are dissected to isolate a 10 cm length of vas deferens, with a paper quadrilateral of 5 cm2 used to delimit the training field. The model covers only the microsurgical step of vasovasostomy once the vas deferens is already isolated. Reported internal and external diameters were 0.2 to 0.4 mm and 2 to 3 mm, and patency was obtained in all procedures performed.

Self-healing leg phantom for femoral vascular access

A vascularised leg phantom developed with clinicians for ultrasound-guided femoral vascular access. The material had a shore OO hardness of 18.0 plus or minus 2.2 and a speed of sound of 1454 plus or minus 15 m/s, and recovered from 18 to 20G needle damage within three hours, so it tolerates repeated punctures.
