Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a multi-

The present invention relates to a surgical tool coupling structure of a multifunctional electrosurgical instrument, and more particularly, to a surgical instrument coupling structure of a multifunctional electrosurgical instrument, including a function of cauterizing an anode current in a single electrosurgical instrument body, The present invention relates to a surgical tool coupling structure of a high-quality, high-quality, multifunctional electrosurgical instrument structured to perform both a grasper function and a dissection function for separating tissue.

Surgical procedures are largely vaginal, abdominal, laparoscopic, and laparoscopic. Recently, there have been fewer cases of scarring, Laparoscopic surgery (hereinafter referred to as "laparoscopic surgery", or "laparoscopy"), which has advantages of less pain, shorter hospitalization days, and quick return to daily life, has been greatly increased.

However, laparoscopic surgery (laparoscopy), ie minimally invasive surgery, also has many drawbacks.

For example, compared with laparotomy, it requires longer operation time, higher cost of medical equipment due to use of expensive medical equipment, possibility of new complication, and necessity of new intensive training.

The increase of the double operation time is mainly due to the frequent replacement of the instrument through the small trocar.

Laparoscopic surgery is done by using electricity, which is called electrosurgery.

Electricity has a bipolar current and a monopolar current. Anodic current causes coagulation / cauterization of tissue, And the unipolar current has a cutting current and a coagulation current so as to cut and cut the tissue, Perform coagulation / cauterization of small vessels (vessels).

 The cutting function is divided into incision and transection. In general, in laparoscopic surgery, a monopolar instrument is used for incision during incision, and transection is a no-current (no-current ) Scissors are used mainly.

The unipolar current can coagulate the blood vessels of the tissue, but the coagulation effect of the blood vessel using the unipolar current is only possible for the blood vessels having a small diameter.

Surgery first closes the blood vessels by coagulating / cauterizing the tissue to be cut, then cutting the coagulated / cauterized tissue and repeating this process many times.

However, most currently available laparoscopic instruments have only one function in a single instrument, so they must be cauterized using an aneurysmal cauterizer, and then the cauterized tissue should be cut with a monopolar cauterizer.

Therefore, as mentioned above, frequent replacement of the instrument through a small trocar is necessary, which not only increases the operation time,

If a hemorrhage occurs at the incision after cutting the cauterized area with an unilateral cauterization, the unicompartmental cauterization can not be performed. Therefore, it must be replaced with an anterolateral cauterizer in order to perform a hemostasis. The amount of bleeding increased, and the amount of blood transfusion also increased.

The electrosurgical instrument is disclosed in Korean Patent Application Nos. 10-2007-9788, 10-2010-7005320, 10-2011-7003357, and 10-2013-7027730.

However, most of the conventional electrosurgical instruments presented here have only one function in one mechanism, and thus there are many restrictions on the use.

SUMMARY OF THE INVENTION The present invention has been accomplished in view of the above problems, and it is an object of the present invention to provide a method of manufacturing a single- A monolithic / bipolar automatic converter (monopolar / bipolar automatic converter) is provided to provide a surgical tool coupling structure of a high-quality, high-quality multifunctional electrosurgical instrument capable of performing both a grasper function and a dissection function for separating tissue. And to selectively use a single-pole current, an anodic current, or a no-current, as needed.

According to an aspect of the present invention, there is provided a surgical tool coupling structure for a multifunctional electrosurgical instrument, the electrosurgical instrument main body having a rear end portion connected to a monopolar / bipolar automatic converter, A main shaft having an upper side fixed to the upper end of which a scissors contact surface is formed on the upper end thereof and a circular pipe whose outer surface is surrounded by an insulating sheath;

And a rear end of the lower claw is hinged to the upper claw so as to be engaged with the upper claw fixed to the front end of the main shaft, A tongue operation shaft having a circular pipe linked to the rear end;

The main shaft is connected to the main body so as to be movable forward and backward while being inserted between the main shaft and the tongue operation shaft. The tip is hinged to the upper gripper so that the blade can be engaged with the upper scissor contact surface of the main shaft And a scissor operation shaft in the form of a circular pipe linked to the rear end of the scissor operation shaft,

When the tongue operation shaft is advanced, the lower claw is opened from the upper gripper around the hinge. On the other hand, when the tongue operation shaft is retracted, the lower grip is closed so that the tissue can be gripped.

The scissors are configured such that scissors are opened from the scissors-contact surface about the hinge when the scissor-action axis is advanced, and the scissors are closed when the scissor-action axis is retracted.

When the present invention is used in combination with a body of the electrosurgical instrument connected to a monopolar / bipolar automatic converter,

It has a function of coagulating / cauterizing with an anode current without replacing a surgical tool, a function of cutting by a unipolar current, a function of cutting with scissors, a grasper function of holding tissue, and a dissection function of peeling tissue The operation time can be greatly reduced.

In addition, if hemorrhage occurs after cauterization / amputation, hemostasis is possible immediately, so the time to hemostasis after bleeding is very short, which can reduce blood loss.

In addition, since there is no frequent replacement of the surgical tool, it reduces the fatigue of the medical staff undergoing surgery.

In addition, without the new hospital enlargement, the number of operation patients per day and day is increased due to shortening of the operation time, and early discharge is possible, which leads to a large increase in the operating room and bedside turnover rate.

In addition, the existing surgical tools have relied almost entirely on imports, but it is possible to save and export foreign currency due to localization.

As described above, the multifunctional complex cautery machine of the present invention is a breakthrough invention that can be used very usefully because various advantages are exhibited in combination.

Meanwhile, a connection shaft 300 is installed between the main shaft 100 and the tongue operation shaft 200 so that the rear end of the shaft can be moved back and forth to the body 2 of the electrosurgical instrument. The tip end of the scissoring operation shaft 300 is connected to the scissors 310 coupled to the hinge 102 to the upper gripper 110 so that the blade can be engaged with the upper scissors contact surface 111 of the main shaft 100. [ As shown in FIG.

Accordingly, when the gripping operation shaft 200 is moved forward and backward, the lower gripper 210 is opened from the upper gripper 110 around the hinge 101, and then the gripper 210 can grip the tissue when the gripper 210 is closed.

In addition, when the scissors operation shaft 300 is moved forward and backward, the scissors 310 are opened from the scissor contact surface 111 with the hinge 102 as a center, and then the tissue can be cut while being closed.

In the present invention, the upper surface of the upper gripper 110 is partially cut when the scissors close face 111 formed on the upper side of the upper gripper 110 fixed to the front end of the main shaft 100 is cut, The scissors 310 are coupled to the hinge 102 to the blade grasping portion 112 formed with the hinge coupling hole 112a so that the blade can be engaged with the scissors contact surface 111, The scissors 310 can be formed thick with a thickness corresponding to the thickness of the scissors 310 and the greatest merit is that the scissors 310 are firmly coupled to the knife gripper 112, Even if the scissors 310 are operated, the scissors 310 do not have any fear of bending, so that the cutting function is smoothly performed. When the scissors 310 are closed, the scissors 310 are minimized in volume so that they can be easily inserted into or removed from the trocar.

An insulator 350 is inserted between the main shaft 100 and the scissors operation shaft 300 so that the main shaft 100 and the scissors operation shaft 300 are inserted into the scissors operation shaft 300 So that electricity can not be conducted to each other.

5 and 6, when the electrosurgical instrument to which the surgical tool coupling structure of the present invention as described above is applied, the lower claw 210 is attached to the upper claw 110 coupled to the front end of the main shaft 100, (Not shown) connected to the electrosurgical main body 2 in an initial state in which both the scissors 310 and the scissors 310 are pinched together with the upper gripper 110 and the lower side 7 and 8, the lever 10 provided in the electrosurgical main body 2 is advanced to be coupled with the pawl actuating shaft holding block 20 And the hinge 101 is coupled to the upper gripper 110 at the distal end of the gripper action shaft 200 by advancing the gripper operation shaft 200 coupled to the gripper action gripping grip block 20 at a forward end thereof, The rear end of the lower claw 210 is linked with the link bar 201 Since it will arise from the front end, while the lower claws 210 around the hinge 101 is rotated to the lower side upper nip 110. The

When the lower claw 210 is opened, the lower claw 210 is positioned in a tissue to be cut. When the lower claw 210 is retracted, the lower claw 210 is closed and the tissue is gripped.

The upper claw 110 fixed to the distal end of the main shaft 100 is fixed while the lower claw 210 is positioned at the center of the hinge 101 in a state in which the upper claw 110 fixed to the distal end of the main shaft 100 is fixed, It is possible to close the blood vessels by coagulating / cauterizing the tissue to be cut.

On the other hand, in the case of cutting the solidified / cauterized tissue using the scissors 310, as shown in FIG. 9, in a state in which no current is supplied, Push the button (31) up.

The fixing protrusion 31a provided on the lock button 31 is released from the locking groove 2a formed in the body 2 of the electrosurgical instrument and is released from the fixed state by the resilient force of the compressed spring 41, The rear end of the scissors operation button 30 linked with the scissors operation piece 40 and the link bar 42 rotates one side of the hinge 30a about the center of the hinge 40a, So that the scissors operation shaft 300 is advanced while the scissor operation shaft grip block 50 linked with the scissors operation piece 40 by the link bar 43 advances.

The upper end of the scissors operation shaft 300 is provided with a scissors (not shown) coupled to the upper scissors 110 so that the blade 311 can be engaged with the upper scissor contact surface 111 of the main shaft 100 310 are linked by the link bar 301, the tip of the scissors 310 rotates upward from the hinge 102 and spreads from the scissors close-contact surface 111.

When the scissors 310 are opened upward, the scissors 310 are positioned in the tissue to be cut. In particular, as shown in FIG. 10, the scissors operation button 30, which has been raised by the elastic force of the spring 41, Press the rear end down.

The rear end of the scissors operating piece 40 linked with the link bar 42 is moved to the rear end of the scissors operation button 30 while the rear end of the scissors operation gripper block 50 advancing while descending around the hinge 40a Thereby retracting the scissors operation shaft 300 while retracting.

The scissors 310 are closed around the hinge 102 so that the cutting edge 311 of the scissors 310 overlaps the scissor contact surface 111 formed on the upper gripper 110 and cuts the tissue. (At this time, since the spring 41 is compressed by the scissor operating piece 40, when the scissor operating piece 40 is subsequently pressed and released, the scissor operating piece 40 is automatically lifted and lowered by the elastic force of the spring 41 The scissors 310 are again open.)

Therefore, the lock button 31, which interrupts the movement of the scissors operation button 30, is pushed up to release the fixation so that the movement of the scissors operation piece 40 is smooth, and then the scissor operation piece 40 is repeatedly The scissors contact surface 111 formed on the upper surface of the upper gripper 110 fixed to the distal end of the main shaft 100 is fixed while the scissors operation shaft 300 is moved forward and backward, Is widened toward the upper side with the hinge 102 as a center, and thus the tissue to be cut can be easily cut by using it.

As described above, the multifunctional electrosurgical machine having the head part coupled to the tool according to the present invention coagulates / cauterizes the tissue using the upper and lower claws 110 and 210 to which the anode current is supplied during the operation, It is possible to cut the coagulated / cauterized region using the scissors 310 without supplying the current immediately, without having to replace it with another surgical tool equipped with the scissors 310,

If bleeding occurs at the cut surface after the cutting, the multifunctional electrosurgical instrument coupled with the head portion of the present invention is immediately supplied with the positive current to the upper claw 110 and the lower claw 210 without needing to replace with another surgical tool Post-hemostasis is possible.

In addition, according to the present invention, the tongue operation shaft 200 is retracted, the lower claw 210 is pinched by the upper claw 110, the scissor operation shaft 300 is retracted, and also the upper claw 110 is scissors It is possible to minimize the volume and to cut the tissue by supplying a unipolar current to the distal end of the tissue.

In addition, it is possible to perform a grasper function of grasping the tissue in a state in which no current is supplied to the upper and lower claws 110 and 210, and to perform a dissection function to peel off the tissue .

The upper part of the upper claw 110 fixed to the front end of the main shaft 100 is partially cut to form a vertically scissor contact face 111. The scissors face 111 is formed with a blade 311, In a state where the scissors 310 are coupled to the hinge 102 and the scissors 310 are firmly coupled inwardly to the knife gripper 112 by inserting the scissors 310 into the knife gripper 112 having the hinge- The thickness of the scissors 310 can be increased by a thickness corresponding to the cutting portion and even if a large force acts on the scissors 310 during the surgical procedure, The cutting function is smoothly performed and the volume of the scissors 310 is minimized so that it is easy to insert or remove the head of the electrosurgical instrument through the trocar.

As described above, when the multifunctional electrosurgical instrument using the surgical tool coupling structure of the present invention is used, the function of coagulating / cauterizing with the anode current without replacing the surgical tool, the function of cutting with a single pole current, the function of cutting with scissors, The grasper function and the dissection function to separate the tissue can be performed, thereby greatly reducing the operation time.

In addition, if hemorrhage occurs after cauterization / amputation, hemorrhage is possible immediately, so the time to hemostasis after bleeding is very short, which can reduce blood loss.

In addition, since there is no frequent replacement of the surgical tools, it is possible to reduce the fatigue of the medical staff performing the operation.

In addition, without the new hospital enlargement, the number of operation patients per day, day, and day can be increased due to shortening of the operation time, and early discharge is possible, which can lead to a large increase in the operating room and bed turnover rate.

In addition, the existing surgical tools have relied almost entirely on imports, but it is possible to save and export foreign currencies due to localization.
