Description

{Electrosurgical scalpel with surgical smoke evacuation tube}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrosurgical instrument, and more particularly, to an electrosurgical instrument with a surgical noxious smoke suction tube capable of effectively removing harmful gas generated during a surgical operation using an electrosurgical instrument.

An electrosurgical instrument is used for surgical operations and is used to apply electrical energy to a living tissue to cause dissection, cauterization or coagulation of the living tissue through protein denaturation. Electrosurgical instruments include laser cutters, laser cutters, electric cutters or electric cutters. When an electrosurgical instrument is used to perform a surgical operation, smoke acts on the living tissue. This is a harmful harmful gas to the human body. It contains living and dead cell tissues including benzene, hydrogen cyanide, formaldehyde and other harmful chemicals, bioaerosols, , Viruses and the like. Hazardous chemicals such as benzene, hydrogen cyanide, and formaldehyde are also known as carcinogens.

High concentrations of noxious gas stimulate the eyes and respiratory muscles of medical staff working at the operating room and can cause problems with the eyesight of the surgeon, especially the surgeon who performs the surgery. It is known that practitioners as well as medical staff working in the operating room can have adverse health effects.

In the United States, the Center for Disease Control and Prevention (CDC) emphasizes the importance of ventilation during surgery and removal of smoke from surgery. It is important to remove the smoke that is generated when the electrosurgical instrument is used in the surgical operation immediately from the site of the injury.

Currently outpatient clinics and operating rooms do not have adequate equipment to remove harmful gases from the use of electrosurgical instruments. Therefore, there is a great need to find a way to effectively remove the harmful gas generated when the electrosurgical instrument is used.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and the manner of achieving them, will be apparent from and elucidated with reference to the embodiments described hereinafter in conjunction with the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The scope of the present invention is defined only by the description of the claims.

FIG. 1 is a view illustrating a configuration of an electrosurgical instrument capable of removing harmful gas according to an embodiment of the present invention. FIG. 2 is a cross- FIG. 3 is a cross-sectional view showing the configuration of a suction tip used in the electrosurgical instrument. FIG. 3 is a cross-sectional view of the electrosurgical instrument according to the present invention shown in FIG. The drawings are shown.

1, an electrosurgical instrument 100 capable of removing harmful gas according to an embodiment of the present invention includes a body 50, an electric action tip 51, a suction tip 10, (56).

The main body 50 is a member having a hollow portion formed inside thereof, and can be a handle when a practitioner grasps the procedure with the hand.

The electric action tip 51 functions as a portion opposed to the living tissue to apply the energy generated by the electric power to the living tissue to treat the living tissue. The form of energy at this time may be thermal energy generated at the tip of the electrical action tip 51 or may be a laser beam emitted from the electrical action tip 51. The electric action tip 51 may be a method of directly contacting the living body tissue to be treated or a method of using it at intervals.

The suction tip 10 is disposed such that the electric action tip 51 passes therethrough. The tip of the electric action tip 51 protrudes outward from the suction tip 10. Preferably, the suction tip 10 is made of a material having excellent heat resistance so as to withstand high temperature heat generated by the action of the electric action tip 51, and the same material as that of the suction tube 56 must be used There is no. Further, it is preferable to be made of a transparent member so as to help secure a view at the time of surgery and to prevent an image by the electric action tip 51. Further, it is preferable that the material is not easily broken even when an impact is applied as in the case of dropping. That is, various commercially available materials including tempered glass, transparent polyimide, and polycarbonate can be used as materials that are excellent in heat resistance and are not easily broken as transparent members.

The length L1 of the tip of the electric action tip 51 protruding from the distal end of the suction tip 10 is preferably in the range of 1.0 mm to 26.0 mm. If the distance is less than 1.0 mm, the protruded length of the electric action tip 51 becomes too short, so that the suction tip 10 frequently touches the living tissue and may be easily contaminated. In addition, when the distance is 26.0 mm or more, the protruding length of the electric action tip 51 becomes excessively large, so that the thin and long electrical action tip 51 may be easily damaged. Furthermore, And the pressure for sucking is too high.

As shown in Fig. 2, the distal end side of the suction tip 10 where the electric action tip 51 protrudes is formed to be smaller in diameter than its rear diameter. By forming in this way, the rear pressure is more likely to be formed, and more harmful smoke can be effectively removed.

The suction tube 56 is connected to the suction tip 10 and is arranged to penetrate the hollow portion of the main body 50 and serves as a duct through which harmful smoke is discharged. The diameter of the suction tube 56 is made equal to or greater than the maximum diameter of the suction tip.

3, the suction tube 56 is relatively moved relative to the main body 50 in the forward and backward directions while being fixed integrally with the suction tip 10 and the electric action tip 51 . Such relative motion can be realized by various technical elements implementing one-way transfer motion. Further, a forward / backward switch 55 may be disposed on the main body so that an operator can easily adjust forward and backward movement of the electric action tip 51.

The electric wire 60 for supplying electric power to the electric action tip 51 is connected to the body 50 so that electric power can be reliably supplied even when the electric action tip 51 is advanced as shown in FIG. And is disposed through the hollow portion. The electric wire 60 also passes through the interior of the suction tip 10 and is connected outwardly through the wall of the portion of the suction tube 56 that is received within the body 50, To the electric power supply unit.

Although only the positional positions of the suction tip 10 and the electric action tip 51 have been described above, the electric action tip 51 may be subjected to a force due to contact with the living tissue or the like Therefore, a structure for supporting the electric action tip 51 may be required.

Fig. 4 is a view showing a structure in which an electric action tip is fixed in a suction tip, and Fig. 5 is a sectional view taken along line V-V of Fig.

4 and 5, the suction tip 10 includes a ring 14 into which the electric action tip 51 is inserted and a ring 14 into which the suction tip 10 A rim 15 for fixing to the inner wall of the body 10 can be disposed. The ring 14 and the rim 15 can be prevented from colliding with the suction tip 10 when a force is applied to the electric action tip 51. The rim 15 here refers to one or more radially extending members connecting the outer side and the central side in a circular cross section, such as the bicycle flesh, and the rim type member is necessary because the rim 15 and the rim 15 So that the electric action tip 51 must be able to be supported without interfering with the flow of the harmful smoke. Although the ring 14 and the rim 15 are disposed on the tip end side of the suction tip 10 in the drawing, the ring 14 and the rim 15 may be disposed anywhere in the suction tip 10 unless the flow of the harmful smoke is interrupted . A step is formed at a portion where the electric action tip 51 abuts against the ring 14, so that the length of the electric action tip 51 that contacts the ring 14 can be maintained.

As a comparative example, in order to remove noxious gas when using the electrosurgical instrument, a tip of the suction line 70 in the vicinity of the tip of the tip of the electrosurgical instrument is installed in parallel with the electric action tip to remove the noxious gas . In this case, the suction tip of the suction line 70 is located in parallel with the electro-surgical instrument tip. In view of the fact that the electro-surgical instrument must be operated while observing the affected part in the surgical operation in many cases, The problem is inevitable. Even if the suction tube arranged in parallel is easy to attach and detach, if the suction tube is not installed, there is still a problem that the choice of the operator may adversely affect the health of the medical staff including the operator. Therefore, it is more effective to dispose the electric action tip 51 through the suction tip 10 as a single body as in the present invention, as compared with a structure in which the electric action tip 51 is disposed in parallel.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. I will understand the point. Therefore, it is obvious that the true scope of the present invention is defined by the technical idea of the appended claims.
