【新型外科手术机器人将投入使用 精准完成微创手术】英国国家医疗服务系统(NHS)宣布明年将使用一款新型机器人Versius,进行各类精细的锁孔手术,如疝气修补等。Versius的四条机械臂能灵活旋转,只需一名外科医生控制。其灵巧度和活动范围较此前的机器人大大提升,体积仅为达芬奇系统的三分之一,且能够完成大多数腹腔镜手术,这些特性有助于其尽快向各地方的医院推广,同时也有助于减轻患者疼痛及术后恢复。

Robot with flexible joints like a human arm and operated by a surgeon using joysticks will perform keyhole surgery on NHS patients by next year

  • Known as Versius, it is a third of the size of robots already used by hospitals
  • This should allow it to perform a wider range of procedures via laparoscopy
  • Robot surgery reduces a patients' pain and speeds up their recovery time 

A new robot with flexible joints like a human will be used by the NHS next year to operate on patients.

Known as Versius, it is a third of the size of robots already used by hospitals, such as the da Vinci Xi system. Experts say this should allow it to perform a wider range of delicate procedures via keyhole surgery, such as hernia repairs.

Each of the robot's four arms has fully-rotating wrists, controlled by a surgeon sitting at a console with two video game-like joysticks and a 3D screen.

This gives surgeons increased dexterity and a magnified view, which is thought to reduce pain and boost recovery times among patients.

A spokesperson from Versius' manufacturer CMR Surgical, told MailOnline: 'Versius mimics the dexterity and range of movement in the surgeon’s own hand and wrist and is designed to be flexible enough to handle the majority of laparoscopic abdominal and pelvic surgical procedures.'

Why use robots over surgeons? 

According to Mark Slack, who co-founded CMR Surgical, teaching surgeons to suture takes around 80 hours. Suturing is a method of closing wounds by holding body tissues together and 'sewing'.

When using Versius, the technique can be mastered in as little as half an hour, he added.

The robot is modeled on the human arm but has a greater range of movement and does not tire.

Dr Hachach-Haram, who is a member of the Royal College of Surgeons' Commission on the Future of Surgery, agrees robots may be able to automatically close wounds, but adds humans will remain in control of operations.

The Versius robot is expected to receive a European health and safety approval mark within the next few months, ready for its launch next year.

Its price is unclear, however, CMR Surgical aims for it to be more cost effective than da Vinci, which costs around £2 million and is used in over 70 hospitals in the UK.

Although expensive, doctors have previously said such systems pay for themselves in the long term by allowing patients to return home quicker with less hospital care requirements.

Martin Frost, CEO at CMR Surgical, said: 'We believe Versius represents a paradigm shift in surgery.

'The ground-breaking design, coupled with genuine affordability, means that patients everywhere have the potential to benefit from the advantages of minimal access surgery.

'Versius is a great example of British innovation and its launch represents a pivotal moment in the next chapter of surgery and patient care.'

How is Versius different to da Vinci? 

Unlike da Vinci, which is around 6ft tall by 6ft wide and weighs three quarters of a tonne, Versius is approximately 2ftx2ft and around a third of the former's weight.

Mr Frost previously said larger robots force surgeons to make use of the limited space around them.

Versius' smaller size means it can be more easily set up and moved between hospital rooms, according to CMR Surgical.

Nadine Hachach-Haram, a plastic and reconstructive surgeon at St Thomas' Hospital, London, told the BBC: 'The newer generation robots are more versatile, compact and cost-effective, which means we can deliver robotic surgery locally and not in large hospitals with dedicated robotic suites.'
