Embodiment

[0045] Multi-spectral spectroscopic fusion surgical guidance system, including light source part, spectroscopic camera part and image fusion part,

[0046] The light source part includes an annular white light LED8 and an annular near-infrared LED9. White light LED with a brightness of 40,000 lux and a wavelength of 400-650nm, which mainly makes the surgical field bright and clear; near-infrared LED excitation light source with a light intensity of 4 mW / cm 2 The light source is arranged in a ring-shaped LED, and all LEDs are controlled by a highly integrated LED driver to keep the output power stable.

[0047] The spectroscopic imaging part includes a close-focus lens 1, a spectroscopic lens 2, a relay lens 3, a filter 4, and a lens barrel 6 connecting the above-mentioned parts together. The lens barrel 6 is made of a light-proof material.

[0048] Close-focus lens 1. The close-focus lens requires a super large aperture of 50mm f / 0.95. To capture images of the surgical field,...

Embodiment 2

[0052] Camera CCD: more than 2 sets, the end of the first refraction light path formed by the beam splitter lens 2 is a color camera CCD 5, which captures the anatomical image of the surgical field and receives the light reflected by the first beam splitter, and the end of the rest of the light path is near-infrared Camera CCD 7 and so on. (This embodiment takes 2 sets as an example)

[0053] Lens barrel 6: The lens barrel 6 is made of light-shielding material, and connects the lens, beam splitter, relay lens and camera CCD together. The overall lens barrel will be fixed on a bracket, and the point signal of the camera CCD will be transmitted through the connection line. The bracket is fixed on the movable mechanical cross arm. The rotation angle of the bracket is 360 degrees, and it has six degrees of freedom of movement. It can realize the electric pitch and rotation movement of the front and back, left and right, up and down of the lens, so that the doctor can get the best...

Abstract

The invention belongs to the technical field of operating field target qualitative positioning for surgical operation, and particularly relates to a multispectral light-splitting fused surgical operation guide system, which is used for solving the problem that a target cannot be distinguished existing in a tumor qualitative positioning technology for surgical operation in the conventional intranperative imaging technology. The multispectral light-splitting fused surgical operation guide system comprises a light source part, a light-splitting image pick-up part and an image fusing part, wherein the light source part comprises an annular white-light LED (Light-Emitting Diode) and a near infrared LED; the light-splitting image pick-up part comprises a near focus lens, a light splitting lens,a relay lens, an optical filter and a lens barrel; and the image fusing part comprises a plurality of video decoders which are connected with the signal output end of a near infrared and color image-pickup CCD (Charge-Coupled Device) respectively. The multispectral light-splitting fused surgical operation guide system has the beneficial effects that: an anatomical color image of an operating field and a near infrared optical image which cannot be seen by naked eyes are shot respectively by adopting spectroscopic photography, and are displayed respectively; and image fusing is adopted, so thatblood vessels, lymph vessels, lymph nodes and fluorescent dye-marked tumor tissues in the operating field can be accurately positioned and displayed.

Description

technical field [0001] The invention belongs to the technical field of qualitative positioning of surgical operation field targets, and in particular relates to a multi-spectrum spectroscopic fusion surgical operation guidance system. Background technique [0002] Surgical resection of tumors is still the most effective way to treat tumors. Radical surgery for tumors refers to extensive resection of the primary tumor, together with en bloc resection of the surrounding lymph nodes. Malignant tumors can infiltrate and spread locally to surrounding tissues. Therefore, the principle of surgical treatment is to resect the primary tumor and possibly involved surrounding tissues, and even resect a certain range of normal tissues to avoid residual cancer cells at the margins. However, the scope of surgical resection is too large, and there are certain sequelae and dysfunction after surgery. Therefore, the scope of tumor surgery has been discussed by clinical surgeons for many year...
