The present invention relates to an eyeglass system for endoscopic surgery, and more particularly, by allowing the doctor to observe the surgical site of the patient in a free posture and to operate while viewing the surgical instruments in a correct posture, the doctor's discomfort is easily reduced and stable. It relates to an endoscopic surgical glasses system to be able to operate with.

In general, a doctor operates on a patient, and is generally divided into an endoscopic operation in which the patient's body is opened through a monitor, while the patient's body is opened and the patient's body is opened by looking at the inside with the naked eye.

Wherein the laparotomy is a large incision through the body wall, and then open the tissue located thereon to be separated by observable and to secure the space necessary to operate the hands and instruments to start the surgical operation, which is a patient A large incision in the body tissue increases the risk of complications, greatly increasing the risk of surgery for the patient's health, and requires a lot of time from initiation to closure of the surgical site. It is necessary.

Therefore, a method of observing and operating the inside of the body by an endoscope has been developed, which is classified into laparoscopic surgery and gastrectomy according to the surgical site.

Laparoscopic surgery, for example, involves drilling a small hole in the patient's abdomen and observing the surgical site of the abdominal cavity through the hole. It is widely used in the field.

The laparoscopic endoscope equipped with a small camera can be inserted into the body and internal organs so that image information detected from the small camera can be observed through a monitor installed externally. To do.

Endoscopic surgery method does not require a large incision through the body wall, and can perform some major surgery painlessly to the patient, the postoperative hospital stay is very short.

However, in the related art, since the endoscope is inserted into the patient's body and the surgical instrument is operated by observing the surgical site through the monitor, the doctor's eyes are directed toward the monitor, which causes discomfort to the doctor. It is difficult to operate the surgical instruments stably, as well as causing unnecessary repetitive manipulations because they are manipulated without looking.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to allow the doctor to observe the surgical site of the patient in a free position and to operate while watching the surgical instrument in a correct posture, It is to provide an endoscopic surgical glasses system that can easily reduce the inconvenience, easy to operate the surgical instruments can easily increase the stability of the surgery.

In order to realize this, the present invention in the endoscope surgical glasses system consisting of operating while observing the surgical site using the endoscope, having a camera lens at the tip and a plurality of lamps and surgical instrument through-holes An endoscope inserted into the surgical part of the patient and connected to the camera signal processor of the endoscope is provided with a camera signal processor for converting the light input from the camera lens into an electrical signal at the end to the electrical signal of the camera signal processor Endoscopic spectacle system, comprising: a controller for outputting an image, a monitor connected to the controller to output an image signal of the controller as an image, and a small display connected to the controller for outputting the image signal of the controller as an image To provide.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a view showing an example of an endoscope surgical glasses system according to the present invention, the glasses system of the present invention is a structure for operating while observing the surgical site using the endoscope (1).

That is, in the spectacles system of the present invention, the endoscope 1 and the controller 2 are connected, and the controller 2 and the monitor 3, the small display 4a of the controller 2 and the glasses 4 are connected. do.

Here, the camera lens (1a) is provided at the front end of the endoscope (1), a plurality of lamps (1b) and the surgical instrument through hole (1c) is provided, the rear end of the endoscope (1) the camera lens (1a) The camera signal processor (1d) for converting the light input from the electrical signal is provided, the end of the endoscope 1 is inserted into the surgical site of the patient.

The controller 2 is connected to the camera signal processor 1d of the endoscope 1 to output an electrical signal of the camera signal processor 1d as an image signal.

The monitor 3 is connected to the controller 2 to output an image signal of the controller 2 as an image, and the small display 4a of the eyeglasses 4 worn by the doctor is connected to the controller 2. Then, the video signal of the controller 2 is output as an image, and is spaced apart in front of the spectacle lens 4b of the spectacles 4.

Since the small display 4a of the glasses 4 is located in front of the doctor's eye, the surgical site is observed by the size of the screen of the monitor 3 at a distance.

On the other hand, as another example of the spectacle system according to the present invention, as shown in Figure 2, a laser light generator 5 for generating a laser light of wavelength 440nm ~ 800nm is connected to the endoscope 1, the laser light generator ( 5) A laser light fiber 5a for transporting the laser light of 5) to the surgical site is disposed between the laser light generator 5 and the distal end of the endoscope 1, and the white light generator 6 for generating white light includes the endoscope ( The optical fiber 6a connected to 1) and transferring the white light of the white light generator 6 to the surgical site is disposed between the white light generator 6 and the distal end of the endoscope 1.

In the glasses system of the present invention, a filter (not shown) for obtaining blue light from white light is installed between the camera lens 1a of the endoscope 1 and the camera signal processor 1d, A spectrum analysis indicator 7 for displaying the generated spectrum comprises a structure connected between the controller 2 and the laser light generator 5.

In addition, the present invention observes the cancer cells at the surgical site with a fluorescence image by a tumor-specific photosensitizer that accumulates in the cancer cells and emits red light by blue light, and simultaneously displays the spectral analysis indicator through the monitor 3 and the small display 4a. Through (7), the spectrum is measured in real time.

In other words, the tumor-specific photosensitive body (photogem, photofrin, hematoporphyrin derivative, or 5-ALA, etc.) is injected into the human body to selectively accumulate and fluoresce in cancer cells of the tissue under test.

In this embodiment, the laser light generator 5 discriminates tumors under mucus by using a He-Ne laser having a wavelength of 632.8 nm. The tissue excited by the He-Ne laser generates long-wavelength fluorescent light. The long-wavelength light reaches the spectrum analyzer 7 through the laser optical fiber 5a, and the cancer is diagnosed early by comparing the spectrum with that of normal tissue.

The spectrum from cancerous tissues is distinct from that of normal tissues, because photogem, a photosensitive agent, accumulates in cancer cells more than normal cells.

Of course, the wavelength of the laser light generated by the laser light generator 5 is preferably 440 nm to 800 nm, which is to obtain a spectrum as described above.

The white light generator 6 is, for example, the same as that known in the art. The white light generator 6 generates white light for viewing the tissue to be examined, and an infrared filter (IR filter) in front of a white light source (Xe lamp) is formed inside the white light generator 6. ), And this infrared filter removes infrared

The white light emitted from the white light generator reaches the tissue of the surgical site through the optical fiber 6a and observes this area.

As described above, after observing the surgical site with white light, the surgical site is observed with blue light. The blue light can be obtained by filtering the white light by a filter in the white light generator.

The white light source of the white light generator 6 becomes blue light by filtering in the filter holder, and reaches to the surgical site by the optical fiber 6a, and the blue light reaching the tissue turns the dark part where the photosensitive agent is accumulated into red. , Normal tissues appear in blue.

The endoscopic surgical glasses system according to the present invention made as described above acts as follows.

First, as shown in FIG. 1, when the doctor inserts the endoscope 1 into the patient's surgical site, the light emitted from the lamp 1b of the endoscope 1 illuminates the surgical site, the endoscope 1 Light reflected from the surgical site through the camera lens (1a) of the input is processed by the camera signal processor (1d) is to output an electrical signal.

Then, the controller 2 receives the electrical signal of the camera signal processor 1d and processes it, and outputs the electrical image signal to the small display 4a of the monitor 3 and the eyeglasses 4. Inserts a surgical instrument (not shown) into the endoscope 1 to observe the surgical site through the small display 4a and is not interfered by the small display 4a through the spectacle lens 4b of the glasses 4. If you do not check the surgical instrument to operate the patient will be able to operate.

On the other hand, while the doctor observes the cancer cells of the surgical site more conveniently, another example as shown in FIG.

That is, a tumor-specific photosensitive agent selectively accumulated and fluoresced in cancer cells among the surgical sites observed by the endoscope (1) is injected into the human body, the endoscope (1) is inserted into the human body, and the camera of the endoscope (1) The surgical site is observed with white light using the lens 1a and the camera signal processor 1d, the white light is filtered to obtain blue light, and the filtered blue light is excited and observed.

The cancer site where tumor-specific photosensitizers accumulate is red, and the normal site is blue.

By observing the spectrum generated by exciting the surgical site with a He-Ne laser light, the spectrum of the cancerous region and the spectrum of the normal region can be clearly distinguished.

After confirming the cancer cells, the surgical instrument is inserted into the endoscope 1, and the surgical instrument is operated outside the human body while observing the surgical region through the small display 4a of the eyeglass 4, thereby safely operating the surgical region of the patient. It can be operated.

As described above, the endoscopic surgical glasses system according to the present invention is operated by operating the surgical instruments around the small display while observing the patient's interior through the small display wearing the glasses, the doctor to operate the surgical site of the patient It can be observed in a free position, and the surgeon's concentration can increase the concentration of the surgeon, and the operation is easy. have.
