Description

Medical laser scissors

TECHNICAL FIELD The present invention relates to medical laser scissors, and more particularly, to medical laser scissors used to cut skin or other tissue using a laser.

In general, when it is necessary to cut the skin or tissue during medical practice, such as surgery, using a conventional scalpel or electric knife. In this case, due to the nature of the tool used, the incision is large, so that general anesthesia is required accordingly, a lot of bleeding can not be avoided during treatment. In addition, there is a problem that the problem of infection occurs, the recovery period is long after surgery, and relatively large scars remain.

In particular, when cutting thin tissues such as the mesentery that contain a lot of blood vessels, ligation of the tissues must be performed to prevent inevitable bleeding. There are many examples of easy tearing, and in some cases, secondary medical problems cannot be avoided due to contraction of tissue caused by ligation or contraction caused by the healing process after using an electric knife.

On the other hand, recently, the use of laser equipment in the medical field is gradually increasing. Medical laser treatment devices possess many advantages over treatment equipment, such as electric cautery and electric scalpels, used in past and present surgery or some other treatment.

Advantages of medical laser treatment devices include

(1) The laser beam, as its name implies, is not electric, but is transmitted as a fine electrical signal when the body stimulus is transmitted along the nerve. Does not affect the signal transmission at all, prevents unexpected nerve damage,

(2) When the laser beam is irradiated, small blood vessels are sealed with the tissue incision, so surgery of a patient with a bleeding tendency or surgery of organs consisting of blood vessels such as the liver or kidney When operating on an organ that is expected to have a lot of bleeding, surgery with a laser knife has almost no bleeding, thus eliminating the need for blood transfusions and preventing from diseases that can be transmitted by blood transfusions such as hepatitis. There are many benefits (bloodless surgery,

(3) sealing the small lymphatic vessels of the tissues with laser beam irradiation to reduce edema resulting from accumulation of lymphatic fluid after surgery, and to prevent cancer cells from spreading through the lymphatic vessels during or after surgery;

(4) Surgery using a laser beam may leave a small scar on the patient after surgery than using a conventional surgical instrument, thereby reducing the greatest cause of reoperation due to postoperative stenosis.

(5) Performing surgery using a laser beam reduces the postoperative pain by sealing the cut nerves of the treatment site (target site),

(6) The laser beam promotes the wound healing process after surgery, so the patient recovers quickly.

(7) When using a laser, bleeding is reduced by bleeding at the same time as the laser beam irradiation, the time required for hemostasis is shortened, so that the operation time is shortened,

(8) Since the laser beam basically uses heat, even if the treatment site has a slight infection, all germs are killed by the heat of the laser beam, which reduces the chance of infection after surgery.

(9) By using the laser, the patient had to be hospitalized because general anesthesia had to be performed in the past, but it was possible to operate with local anesthesia rather than general anesthesia, thereby saving valuable time and treatment cost of the patient. Many advantages have been reported.

The present invention has been made to overcome the disadvantages of the prior art as described above, and can be performed more effectively and safely by using the characteristics of the laser as described above, rather than a general surgical scalpel or electric knife at the time of treatment such as surgery. The technical challenge is to provide laser scissors that can shorten the operation time.

25…. projection part.

The present invention in order to achieve the above technical problem, the handle is formed on one end and the first body is formed with an absorbent portion on the other end; At one end, a handle is formed, and at the other end, a second body in which a laser light emitter is formed is rotatably coupled to each other, and a plurality of optical fibers connected to a laser oscillator are inserted into the second body and absorbed from the light emitter. It is characterized by emitting a laser toward wealth.

The first body and the second body is similar to the shape of a general scissors, but since the blade portion of the existing scissors may be replaced by the absorbing portion and the light-emitting portion, respectively, in the present invention specific for the specific shape of the other parts I never do that.

The laser beam is emitted from the oscillator located outside to the light exit portion through the optical fiber, and the optical fiber is inserted into the second body. The oscillator may use a general laser oscillator, preferably using a semiconductor laser diode.

In addition, in the laser scissors, the absorption portion has a flat rectangular cross section, the remaining portion except the light-emitting portion is coated in black that can absorb the laser beam, the light-emitting portion facing the absorption portion Another aspect is that the ends of the optical fiber are arranged in a plurality of rows along the longitudinal direction.

Through such a configuration, the laser in the oscillator can be uniformly emitted to the absorbing part, and the remaining part except the outgoing part is coated in black, preferably ebony (black), ebonized, and the laser beam This prevents reflections on unwanted parts.

The present invention is also characterized in that, in the laser scissors, the laser level of the column located at the center among the rows in which the optical fiber is arranged is higher than the energy level of the remaining columns.

Therefore, a laser beam having a relatively high energy level cuts or ablates tissues or organs, and a laser beam having a low energy level located on both sides may discharge blood from a lymph node or an outflow of a lymphatic vessel that may occur at the incision surface or the cut surface. It will help to prevent the outflow of lymphatic fluid.

In addition, the light emitting portion may be formed so that the portion is arranged the end of the optical fiber is projected, it may be formed on both edges of the light emitting portion protruding toward the absorbing portion along the longitudinal direction.

Preferably, when the spring is installed between the handle of the first body and the second body so as not to apply a force to the handle, the first body and the second body may be separated from each other at a constant angle.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of a laser scissors according to the present invention.

As shown in Fig. 1, the embodiment has a shape similar to that of conventional scissors as a whole. That is, the first body 13 and the second body 22 are hingedly coupled to each other and rotatably fixed to each other, and the handles 10 and 20 are formed at the ends, respectively. The leaf spring is fixed between the handles 10 and 20 so as to maintain a space therebetween when no force is applied to the handles 10 and 20.

An absorbing portion 11 is formed in the blade portion of the first body 13. The absorption part 11 has a rectangular cross section, and the surface facing the light exit part 21 is flat. The light exit portion 21 is formed in the blade portion of the second body 22. As shown in FIGS. 2 and 3, three rows of optical fibers 23 are arranged along the longitudinal direction at the tip portion 24 of the light exit portion 21. The rows of the optical fibers 23 located at the center of the three rows of optical fibers 23 are arranged more densely than those located at both sides, and as a result, a laser having a stronger energy level is output. The energy level can be adjusted by changing the density at which the optical fiber 23 is disposed. When the optical fiber 23 uses a plastic coated silica fiber (PCSF) coated with plastic, it is possible to reduce the loss of light generated during the laser beam transmission process.

In the embodiment shown in FIG. 2, the light exit portion 21 is configured to be in direct contact with the treatment site, but as shown in FIG. 4, the light exit portion 21 is formed by forming protrusions 25 on both sides. It can also be configured as a non-contact type without contact.

The optical fiber 23 is connected to an oscillator located outside through a passage (not shown) formed inside the second body 22. The oscillator may use a conventional laser oscillator, and may use a semiconductor laser diode. The oscillator is provided with the same foot switch as a general laser therapy device.

On the other hand, in the above embodiment, all of the remaining portions except the portion where the laser is emitted is coated in ebony (Black) color. Therefore, the emitted laser is not reflected but is all absorbed by the absorbing portion 11.

The operation of the above embodiment will be described.

When the oscillator is operated for the procedure, the laser beam is emitted in three rows toward the absorber 11 through the light emitter 21. The laser beam located at the center has a high energy level, so the tissue is cut or excised, and the laser beam located at both sides prevents the outflow of blood from the blood vessels or lymphatic fluid from the lymphatic vessel, which may occur at the incision surface or the ablation surface. To prevent it.

According to the present invention having the configuration as described above, the tissue can be incised or resected using a laser beam but using a method different from the conventional laser knife, so that the patient inevitably suffers from bleeding during the procedure. It can minimize the degree of damage of the living body, including the side effects can be minimized.
