Description

[0001] The present invention relates to a photodynamic therapy endoscope,

The present invention relates to a photodynamic therapy cap and an endoscope combined therewith. More particularly, the present invention relates to a photodynamic therapy cap capable of effectively irradiating light to as many sites as possible, and an endoscope combining the same.

In the past, the treatment of various pathogens including bacteria has been mainly performed using antibiotics. However, recently, treatment with these antibiotics has caused infection by pathogens such as various bacteria (so-called super bacteria) resistant to antibiotics The mortality rate is increasing.

On the other hand, in cases where the patient's antibiotic compliance is low, or when the patient is allergic to antibiotics and difficult to treat with antibiotics, development of a therapeutic method that can replace antibiotics is required.

To solve this problem, a wide-band dynamic therapeutic apparatus using light of a specific wavelength within a limited space such as the gastrointestinal tract (gastrointestinal tract) has been developed. However, in order to sterilize a bacterium using a photodynamic method, It is necessary to develop a device for reducing the inconvenience of the patient by reducing the procedure time by minimizing the time and for the operator to easily treat it. To this end, it is necessary to develop a device that can irradiate more light at the same time than a simple rod for irradiating light.

The endoscope according to an embodiment of the present invention includes an endoscope body 1; A cap body 10 coupled to a distal end of the endoscope body 1; And a light irradiation unit 12 coupled to the cap body 10 so as to be able to expand and contract, and to irradiate light into the human body in an expanded state.

The endoscope body 1 is made of a cable material which can be inserted and discharged into the human body. A camera 2 for photographing the inside of the human body is provided on the front surface of the endoscope body 1 and a working channel 4 into which surgical instruments (not shown) are inserted is formed. The working channel 4 may be formed as a plurality of channels extending along the endoscope body 1. Thus, the surgical tools are inserted and discharged along the working channel 4 so that the operation can proceed.

As the surgical instrument, for example, any one of a clamp, a scissors, and a clamp can be selectively used to perform surgery or incision of the affected part, and a hook, a scalpel, a pin, and an electric pocket A device for burning tissue by heat generated by flowing a high current and performing incision or hemostasis) may be selectively used.

At the distal end of the endoscope body 1, a photodynamic therapy cap is coupled. Photodynamic therapy cap increases the detection rate of the endoscope by pushing the curved internal wall with the endoscope inserted.

The overall appearance of the photodynamic therapy cap is formed by the cap body 10. The cap body 10 is formed into a substantially hollow cylindrical shape and is coupled to the distal end of the endoscope body 1 through a rear end inner surface. The cap body 10 is made of a transparent material so that it can be photographed outside through the camera 2. [

In this embodiment, the light irradiation unit 12 is coupled to the cap body 10 so as to be able to expand and contract. A plurality of light irradiation units 12 may be provided at the tip of the cap body 10, and a plurality of light irradiation units 12 may be disposed along the circumferential direction. FIG. 1 shows a light irradiation part 12 in a rounded state at the tip of a cap body 10. That is, the light irradiation unit 12 has a structure similar to that of an 'elephant flute', and when it contracts, it keeps its rounded state as shown in FIG. 1, and when it expands, it spreads toward the front as shown in FIG. The light irradiating unit 12 has an elastic force so as to maintain a rounded state, and when the supply of the fluid after the inflation is stopped, it returns to a rounded state. In addition, the light irradiating unit 12 can be kept folded inward as shown in Fig. 1 for smooth insertion of the endoscope.

In the present embodiment, the light irradiation unit 12 is configured as described above in order to maintain the shaded state of the light irradiation unit 12 in the process of inserting the endoscope so that insertion of the endoscope is smooth. Further, in the state where the endoscope is inserted into the human body, the light irradiation unit 12 is expanded and unfolded, so that light can be irradiated. In this case, the light irradiation unit 12 can effectively irradiate light to various parts at the same time.

In addition, in the present embodiment, when the light irradiating unit 12 expands so as to irradiate light more effectively, it is configured to spread radially forward as shown in Fig. With this configuration, since the light irradiating unit 12 radiates light while radiating it, it is possible to effectively irradiate the entire built-in wall with light.

On the other hand, the light irradiating unit 12 may be provided with a light source 13 such as an LED capable of irradiating light of a specific wavelength depending on causative bacteria (see FIG. 4). That is, the light source 13 irradiates light to a specific region in a state where the light irradiation unit 12 is unfolded, thereby facilitating photodynamic therapy. In the above description, the light source 13 directly irradiates the light. However, the present invention is not limited thereto. The light irradiating unit 12 itself may be formed of a light emitting unit capable of emitting light, or the light irradiating unit 12 may be made of a transparent material It is also possible to irradiate light with a light source provided therein. It is also possible to maximize the light irradiation effect by configuring the light irradiation unit 12 itself as a light emitting unit and providing the light source 13 on the inner and outer surfaces of the light irradiation unit 12.

On the other hand, a fluid supply line 14 for expanding and contracting the light irradiation unit 12 is connected to the rear end of the light irradiation unit 12. The fluid supply line 14 is connected to the pump and serves to supply a fluid such as air to the inside of the light irradiation unit 12. That is, the fluid supply line 14 does not supply the fluid at the time of inserting the endoscope but inserts the endoscope into the inside of the human body, and then supplies the fluid so that the light irradiation unit 12 can be inflated.

1, the fluid supply line 14 may be elongated along the outer surface of the endoscope body 1 and may include a plurality of fluid supply lines 14 provided on the outer surface of the endoscope body 1 to prevent the fluid supply line 14 from flowing. Can be fixed by the support ribs (20). A plurality of support ribs 20 may be provided along the longitudinal direction of the fluid supply line 14 at predetermined intervals. Further, the front and rear ends of the support ribs 20 (with respect to the inserting direction of the endoscope) may be curved to minimize damage to the inner wall of the human body as shown in Fig.

Referring to FIG. 3, the fluid supply line 14 may be installed to penetrate the support ring 120, which is coupled to surround the outer surface of the endoscope body 1. At this time, a plurality of fluid supply lines 14 may pass through one support ring 120 along the circumferential direction as shown in FIG.

5, the light irradiating unit 12 may be configured so that the reinforcing member 16 passes through the center. The reinforcing member 16 provides an elastic force to keep the light irradiation part in a rounded state. Therefore, the light irradiation unit 12 can be held with greater rigidity in the unfolded state, can be returned to the original rounded structure due to its elasticity, and stable light irradiation can be performed in a wide area.

According to the embodiment described above, it is possible to treat a causal organism in vivo without using an antibiotic by using broad band dynamic therapy, and it is possible to use broad band therapy while using an endoscope.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as set forth in the following claims It will be understood that the invention may be modified and varied without departing from the scope of the invention.
