Problems solved by technology

[0011] However, since the position and size of blood vessels passing through tissue vary from patient to patient, it is difficult to obtain accurate information about the presence and size of blood vessels in tissues only from the intensity information of light signals passing through tissues
Also, if the device malfunctions, it can pose a considerable risk to the patient during the procedure
The probability of accidental resection of blood vessels during actual surgery is about 3%, and the probability of fatal injury in these cases is about 18%, so billions of dollars in treatment costs due to accidental resection of blood vessels
[0012] In addition, according to the prior art, light is widely irradiated to the tissue to be observed, and the intensity of the light passing through the tissue is collected by a light collection device such as a CCD, therefore, the manufacturing cost of unnecessary modules is high, which is not economical

no. 1 approach

[0061] A tissue resection system equipped with a tissue resection device according to a first embodiment will be described below.

[0062] ●Tissue resection device

[0063] Such as figure 1 and figure 2 As shown, the tissue resection device 100 includes a resection unit 110 , an extension part 120 and an optical signal transmission module 140 .

[0064] The cutting unit 110 is inserted into the human body to grasp or cut the human tissue 10 . An optical signal transmission module 140 for line-scanning a portion to be resected from the human tissue 10 is provided in the resection unit 110 . A second optical signal transmission module 150 operating independently of the optical signal transmission module 140 may also be provided in the cutting unit 110 .

[0065] The optical signal transmission module 140 and the second optical signal transmission module 150 may be configured to provide a reflected optical signal or a reflected second optical signal to the image generation u...

no. 2 approach

[0156] A tissue resection device 100a and a tissue resection system 200a using the tissue resection device 100a according to a second embodiment of the present invention are described below.

[0157] The tissue resection device 100a according to the present embodiment is the same as the first embodiment described above in terms of structures and functions of the resection unit 110 , the extension 120 , and the actuator 130 . In addition, the installation positions and structures of the optical signal transmission module 140a and the second optical signal transmission module 150a are the same as those of the optical signal transmission module 140 and the second optical signal transmission module 150 of the above-mentioned first embodiment, therefore, the following description of the optical signal transmission module 140a and the second optical signal transmission module 150a are different from the first embodiment.

[0158] In this embodiment, the optical signal transmission m...

no. 3 approach

[0166] Refer below Figure 15 to Figure 19 A tissue resection device 300 according to a third embodiment of the present invention and a tissue resection system 200b using the same will be described.

[0167] Such as Figure 15 to Figure 18 As shown, the tissue resection device 300 according to this embodiment includes a resection unit 310, an extension part 320, an actuator 330, a pair of optical signal transmission modules 340a and 340b, and a pair of second optical signal transmission modules.

[0168] The cutting unit 310 , the extension part 320 and the actuator 330 of the present embodiment basically have the same functions as the cutting unit 110 , the extension part 120 and the actuator 120 of the first embodiment described above. In addition, the pair of optical signal transmission modules 340a and 340b and the pair of second optical signal transmission modules are functionally and structurally the same as the optical signal transmission module 140 and the second opti...

Abstract

A tissue excisor according to an embodiment of the present invention comprises: an excising part capable of being inserted into a human body and having a structure that can excise human tissue; and anoptical signal relay module built into the excising part to be capable of moving forward and backward along the lengthwise direction of the excising part, and providing an optical signal to human tissue, wherein the optical signal relay module preferably collects the optical signal reflected by the human tissue while moving forward and backward along the lengthwise direction and line-scans the human tissue.

Description

technical field [0001] The present invention relates to tissue resection systems, and more particularly, to a tissue resection system capable of displaying images obtained by allowing scanning of human tissue via lines, even without a camera module inserted into the human body. Internal images of resected tissue to visually observe the presence and size of blood vessels to minimize damage during surgery due to accidental resection or blood vessels. Background technique [0002] In medical terms, surgery means surgery to treat disease by cutting or removing skin, mucous membranes or other tissue with medical tools. Abdominal surgery in medical surgery is an operation in which a person's abdominal cavity or skin is cut open and then treated, undergoing plastic surgery, or removing internal organs. [0003] In abdominal surgery, the patient's skin is cut to form a predetermined space through the skin and tissue, and then the operation is performed in this space, so a large sca...
