Set comprising a surgical instrument
The invention relates to a correlated set for minimal invasive surgery comprising a surgical instrument and a pattern generating member, a surgical system, a training kit, a method of training and a method of performing a minimal invasive surgery. The surgical instrument comprises a handle portion, a surgical tool and a body portion connecting the handle portion to the surgical tool. The pattern generating member comprises a pattern light source and a projector for projecting a light pattern. The projector is adapted for being at least temporarily fixed to the body portion of the surgical instrument such that a movement of said surgical tool results in a correlated movement of said projector.
1. An apparatus for minimally invasive surgery, comprising:
a surgical instrument comprising a body portion and a surgical tool disposed at the distal end of the body portion; and
a projector disposed on an exterior surface of the body portion, the projector having an outer surface including a plurality of light-emitting areas configured to project a light pattern onto tissue, the plurality of light emitting areas arranged on the outer surface such that distally-disposed light-emitting areas of the plurality of light-emitting areas project the light pattern at a first angle relative to a longitudinal axis of the body portion, and proximally-disposed light emitting areas of the plurality of light-emitting areas project the light pattern at a second angle relative to the longitudinal axis of the body portion, the second angle different from the first angle.
2. The apparatus of claim 1 , wherein the projector includes at least one of a phase optic element, a spatial light modulator, a multi-order diffractive lens, a holographic lens, a Fresnel lens, a computer regulated optical element, a mirror, a filter, and a splitter.
3. The apparatus of claim 1 , wherein the light pattern, when projected onto the tissue, comprises a plurality of angled lines.
4. The apparatus of claim 1 , wherein the light pattern, when projected onto the tissue, comprises a grid pattern.
5. The apparatus of claim 1 , wherein the projector is spherically shaped.
6. The apparatus of claim 1 , wherein the projector is cylindrically shaped.
7. A surgical system, comprising:
a surgical instrument comprising a body portion and a surgical tool disposed at the distal end of the body portion;
a projector disposed on an exterior surface of the body portion, the projector having an outer surface including a plurality of light-emitting areas configured to project a light pattern onto tissue, the plurality of light emitting areas arranged on the outer surface such that distally-disposed light-emitting areas of the plurality of light-emitting areas project the light pattern at a first angle relative to a longitudinal axis of the body portion, and proximally-disposed light emitting areas of the plurality of light-emitting areas project the light pattern at a second angle relative to the longitudinal axis of the body portion, the second angle different from the first angle;
a camera configured to acquire an image of the light pattern projected onto the tissue; and
a monitor configured to display the acquired image.
8. The surgical system of claim 7 , wherein the camera is an endoscope.
9. The surgical system of claim 7 , wherein the camera is in data connection with a computer programmed to monitor the movements of the surgical tool of the surgical instrument.
10. The surgical system of claim 7 , further comprising a computer configured to analyze the acquired image.
11. The surgical system of claim 7 , wherein the camera is operatively connected to the monitor.
12. The surgical system of claim 7 , wherein the projector is spherically shaped.
13. The surgical system of claim 7 , wherein the projector is cylindrically shaped.
