Robot for otorhinocranial base minimally invasive operations and operation method thereof

Abstract

The invention provides a robot for otorhinocranial base minimally invasive operations and an operation method thereof, comprising a linear movement mechanism, a rotation mechanism, a deflection control mechanism, a clamp control mechanism and a continuous body mechanism, wherein, the linear motion mechanism and the rotating mechanism drive the deflection control mechanism, the clamping mechanism and the continuous body mechanism to move and rotate integrally so as to make the continuous body mechanism reach the preset position; the continuous body mechanism comprises a continuous body support,a plurality of continuous body joints, a nickel-titanium tube embedded in the continuous body joints, a clamp fixture and a clamp; the deflection control mechanism and the clamping mechanism controlsthe continuous body mechanism to perform the deflection action back and forth through the wire, and clamping or loosening of the clamp; and the robot is used for minimally invasive operations of theotorhinocranial base. The robot is used for otorhinocranial base minimally invasive operation, has the advantages of smaller size, larger bending angle and simple operation, can meet the needs of clinical operation, has high operation accuracy and good repeatability, can shorten the doctor's training cycle and reduce the operation risk.

Description

technical field [0001] The invention relates to a medical device, in particular to an ear, nose and skull base minimally invasive surgery robot and an operation method thereof. Background technique [0002] Ears, nose, and skull base are one of the most complex areas of the human body, including the external auditory canal, tympanic cavity, Eustachian tube, labyrinthine duct, and internal auditory canal; nasal cavity, sinuses, and nasopharynx; anterior skull base, sella region, and lateral skull base, etc. Due to the curved cavity and narrow space when entering the lesion, there are many surgical blind spots in otolaryngology and skull base surgery, making minimally invasive surgery difficult. [0003] Recently, natural orifice transluminal endoscopic surgery (Natural Orifice Transluminal Endoscopic Surgery) is the trend of minimally invasive and non-invasive surgery. This type of surgery has many advantages, such as minimal incision in the affected area, short operation ti...

AI Technical Summary

Problems solved by technology

It can perform operations such as bending, shrinking, and grasping in multiple directions. However, for more complicated otolaryngology and skull base surgery with natural orifices, the bending degree of the flexible continuum and the size of the robotic arm obviously cannot meet the surgical requirements.
