Minimally invasive surgical module

Abstract

A minimally invasive surgical module includes a light transmission unit having a light emitting end, a containing unit having an containing recess and a first reflecting surface located on an optical axis of the light transmission unit at the light emitting end, and an light path switching unit having a recess and a second reflecting surface, wherein the first reflecting surface and the second reflection surface are inclined with respect to the optical axis and located on the inner wall of the containing recess and the inner wall of the recess, respectively. The containing recess contains the light emitting end. The light path switching unit is adapted to switch between a first position and a second position. The light from the light emitting end is reflected by the first reflecting surface and the second reflecting surface in sequence when the light path switching unit is switched to the first position. The light from the light emitting end is reflected by the first reflecting surface and then transmitted to the outside from a side of the light path switching unit. The minimally invasive surgical module has a switchable light emitting direction, and the convenience and safety of minimally invasive surgery can be improved.

Description

technical field [0001] The present invention relates to a surgical assembly, and in particular to a minimally invasive surgical assembly. Background technique [0002] In recent years, with the progress of medical technology, minimally invasive surgery (minimally invasive procedure) has gradually replaced the traditional surgical operation. With the advancement of optical technology and with appropriate light sources, minimally invasive surgery can irradiate the soft tissue in the patient's body that needs to be removed through the combination of endoscope and optical fiber. Vaporization by the light beam emitted from the optical fiber. [0003] The above optical vaporization of soft tissue has the advantages of less blood loss, high safety and fast recovery, and has gradually been widely used in Urology surgery, such as the removal of enlarged prostate . However, because minimally invasive surgical instruments introduce the light beam irradiated by an external light sour...

AI Technical Summary

Problems solved by technology

However, because minimally invasive surgical instruments introduce the light beam irradiated by an external light source through the optical fiber, the optical fiber is irradiated along a fixed direction (for example, directly in front of the endoscope), so it is impossible to change the light beam during the operation according to the needs of the operation. Irradiation direction (e.g. the side of the endoscope)

Therefore, under the premise that the illumination direction of the minimally invasive surgical instrument cannot be changed, it will cause inconvenience during the operation, and it is necessary to use more complicated operation methods to deal with soft tissues in various directions, thereby increasing the time required for the minimally invasive surgical instrument during movement. unnecessary harm
