Customised Instruments
for Minimally Invasive Manipulation in Cervical Oncological Surgery
Abstract:
The Oncological
Abdomino-Pelvic Surgery Reference Unit (UR-COAP) of the General
University Hospital of Castellón, devoted to multidisciplinary
oncological surgery, has developed a series of instruments for the
handling of tumours and/or organs in the course of cancer surgery.
Recent studies point to the need to design a uterine manipulator
that does not injure the initial uterine cervical tumour. Given the
variability of the size of the cervix/tumour and the dimensions of
the vagina in women, it would be very appropriate to be able to
design a specific uterine manipulator for each woman and each tumour,
which could be based on the medical images obtained from the
patient, generating the models for the manufacture by 3D printing of
such a customised manipulator.
Besides, the Biomechanics and Ergonomics Group (BE-UJI) and the
Institute of Advanced Materials (INAM) of the Universitat Jaume I
have experience in different 3D printing techniques and materials.
The three institutions have joined efforts under the call for
UJI-SABIO projects (UJI-FISABIO collaboration programme, http://ujisabio.uji.es)
to tackle the following objectives in this first year:
1. Creation of a bank of anonymised images that will be a test bench
for the techniques necessary for the materialisation, by 3D
printing, of this type of final actuator for the manipulator.
2. Study of the state of the art of existing uterine manipulators,
as a starting point for total or partial redesign.
3. Study of the most suitable printing techniques and biomaterials
for this final actuator. Carrying out physical tests to evaluate the
qualities of the 3D prints obtained with these biomaterials.
4. Study of the surface treatment of the biomaterials used,
evaluating the possibility of adding virucides or other agents that
minimise the risk of migration of the human papillomavirus (HPV),
the cause of this type of cancer.
5. Generation of the first printed prototypes for simulated
evaluation (outside the operating theatre) of their resistance and
manipulability.
