In general, an endoscope is an internal view of a hollow growth phase, such as a stomach or esophagus, or an internal view of a body such as a chest cavity or an abdominal cavity. It is a generic term for medical instruments that can be used, and it is subdivided into various kinds such as bronchoscope, laryngoscopy, esophagus, gastrointestinal, uterus, urethra, arthroscopy, bladder, rectal, laparoscopic, heart, etc. It is a medical aid that helps the discovery and diagnosis of the disease and its treatment by observing the state inside the human body and at the same time to facilitate the removal of tissue and collection of secretions.

This endoscope-based surgery (procedure) is less damage to the tissue and excellent in cosmetics, replacing the conventional conventional surgery in the field of thoracic surgery or abdominal surgery, and recently, due to the development of various endoscopes and small endoscopy instruments The range is getting wider.

In particular, in the case of thyroid disease, which occurs mainly in women, thyroidectomy through the frontal skin incision was safe and effective, but it was not cosmetically good due to the scars of the incision remaining on the front of the neck after surgery.

For example, in the case of thyroid surgery, there are various endoscopy methods such as the breast approach, breast approach, and cervical approach, but recently, the axillary approach has been mainly used.

The initial endoscopic resection using the axillary approach had to inject carbon dioxide gas to secure the surgical space. Accordingly, complications such as increased PaCO ₂ , subcutaneous swelling and severe tachycardia, and complicated procedure equipment were required. .

Accordingly, it was urgently required to develop a retractor that induces a simple and easy endoscopy procedure without additional side effects while ensuring sufficient surgical space without injecting carbon dioxide gas during endoscopy.

The present invention has been made in view of the above-described problems of the prior art as described above, and secures sufficient space for the procedure during endoscopy, while maintaining nerves, blood vessels, tissues, and other human bodies distributed around the treatment site. The main purpose is to provide an endoscopic retractor for guiding to ensure the ease of the procedure while minimizing damage to the internal organs.

The present invention to achieve the above technical problem, the mainframe; A space securing frame integrally fixed to the lower end of the main frame and having a hollow portion of a predetermined shape to secure a surgical space; A plate-shaped lower spoke extending horizontally from the bottom surface of the space securing frame; A support frame protruding in the direction of the lower spoke at the interruption of the main frame; A connection frame arranged on the support frame to be rotated about a rotation axis; An upper spoke fixed to the lower end of the connecting frame and having a shape similar to the lower spoke and extending inclined toward the lower spoke; The technical feature is to provide a retractor for the thyroid endoscope which is engaged through the main frame in the form of a screw, one end is in contact with the rear surface of the connecting frame, the other end comprises an adjustment shaft with a control handle.

In this case, the space securing frame may be formed in a C shape or a rectangular frame shape, and furthermore, a portion of the extended tip of the upper spoke and the lower spoke is preferably formed to be bent in a direction facing each other.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

1 is an exemplary perspective view of an endoscope surgical retractor according to an embodiment of the present invention, Figure 2 is a side view showing an exemplary operating state of the endoscope surgical retractor according to an embodiment of the present invention, Figure 3 is Exemplary perspective view of an endoscope surgical retractor according to another embodiment of the invention.

1 and 2, the retractor of the present invention is provided with an upper spoke 150 and a lower spoke 160 which are movable around a main frame 100 having a rectangular bar shape, such that a surgical site, for example, axillary (armpit) is installed. ) Loosen the incised tissue up and down.

To this end, a space securing frame 110 having a C shape is connected and fixed to the lower end of the main frame 100 so as to sufficiently secure the surgical space during the procedure.

In addition, the lower surface of the space securing frame 110 is relatively thin and the width becomes narrower toward the front, that is, the lower spoke 160 forming a trapezoidal shape is firmly fixed integrally.

At this time, the tip of the lower spoke 160, that is, a part of the opposite end of the portion connected to the space securing frame 110 is preferably inclined at a slight angle in the form of a downward curved line, which is appropriate for the tissue of the treatment site. This is to keep the tissue from slipping down so that it is in close contact.

On the other hand, the upper end of the main frame 100 is integrally formed with a holder 190 that provides ease for gripping and storage, the support frame 120 in the direction orthogonal to the longitudinal direction of the main frame 100 ) Is protruding.

Here, the support frame 120 is preferably formed to protrude in the same direction as the direction in which the lower spoke 160 protrudes.

The connecting frame 130 is axially coupled to the protruding end of the support frame 120 so that the connecting frame 130 can be freely rotated in the vertical direction by the rotation shaft 140.

To this end, the upper end of the connection frame 130, that is, the portion axially coupled to the support frame 120 has a cutout 132 cut into a substantially rectangular shape.

Accordingly, the connection frame 130 is configured to be freely rotatable about the rotation shaft 140 without interfering with the support frame 120.

Here, the connection frame 130 should be disposed to be located at a position higher than the lower end of the space securing frame 110, the step (height difference) may have a deviation depending on the subject, but maintained at approximately 60mm or more Preference is given.

In addition, the lower end of the connecting frame 130 is fixed to the upper spoke 150 is integrally formed, the upper spoke 150 is also formed to correspond to the same shape as the lower spoke 160.

At this time, the lower spoke 160 extends horizontally from the lower end of the space securing frame 110, and only a portion of the end portion thereof is bent inclined downwardly, whereas the upper spoke 150 faces the lower spoke 160. It is preferably formed to be inclined to extend from the bottom of the connecting frame 130, the end is bent to be slightly curved in the upper direction opposite to the lower spoke (160).

On the other hand, on the main frame 100, which is a lower position of the support frame 120, the adjustment shaft 180 is installed through in a direction opposite to the support frame 120.

The adjustment shaft 180 is a screw shaft form, the screw thread is formed in part or all of its length and the end protruding toward the support frame 120 through the main frame 100 is the rear surface of the connection frame 130 Is supported in contact.

In this case, a through hole (not shown) is formed at a point through which the adjustment shaft 180 of the main frame 100 penetrates, and a thread thread engaged with a screw thread formed in the adjustment shaft 180 is processed on an inner circumferential surface of the through hole. Of course it is.

And, the other end of the adjustment shaft 180, that is, the control handle 170 that is easy to grip is fixed integrally to the opposite side end from which the support frame 120 protrudes.

Therefore, when the adjustment handle 170 is rotated in the clockwise or counterclockwise direction (because the adjustment handle forward and backward is determined according to the direction of the thread formed on the adjustment shaft), the adjustment shaft 180 is moved forward or backward. When the forward is pushed up the connecting frame 130, and when the reverse has a clearance with the connecting frame 130. The upper spoke 150 including the connecting frame 130 is a member having a weight As it falls down, the play is reduced.

Figure 3 shows another embodiment of the retractor of the present invention, the other components are similar to the above-described embodiment of Figures 1 and 2, but the space securing frame 110 'is formed of a hollow rectangle, that is, a rectangular frame body Is the point.

The difference between the space securing frame (110, 110 ') is that the first side of the C-type is drilled in one side, there is an advantage that the use of surgical instruments is convenient, but in terms of stability (support map) of the rectangular frame shape, In the case of high stability, but less than the C type in the use of surgical instruments it is preferable to employ selectively employed as necessary.

The operating relationship of the present invention having such a configuration will be described by way of example in the case of thyroid procedures.

First, the patient is anesthetized and placed on the operating table with the supine position. Then, the neck is stretched and the arm on the lesion side is directed toward the ipsilateral head and neck, so that the axilla is easily exposed, thereby reducing the distance between the axilla and the thyroid gland.

Subsequently, an incision of approximately 7 cm in size is made on the axillary recessed portion of the lesion, and the flap is peeled between the subcutaneous layer and the pectoralis muscle to access the clavicle, and a tunnel is formed between the subcutaneous layer and the thorax ductus muscle.

When the tunnel is formed to secure the surgical space using the present invention retractor.

That is, the upper spoke 150 and the lower spoke 160 constituting the retractor of the present invention, as shown in Figure 1, the two spokes 150, 160 are in contact with each other in contact with each other the tip of the tip into the cut-in tunnel Insert it.

Subsequently, when the control handle 170 is rotated in a predetermined direction while the main frame 100 is firmly gripped, the control shaft 170 moves forward and pushes the connecting frame 130.

Accordingly, the connecting frame 130 is pushed up while being rotated about the rotation shaft 140, and eventually the upper spoke 150 is opened while gradually spaced apart from the lower spoke 160.

As this process is repeated, the incision tunnel is maintained with the incision open with sufficient space for surgery.

When sufficient space is secured for surgery, the operator grasps the surgical instrument and inserts the surgical instrument (other instruments including the endoscope) into the hollow portion of the space securing frame 110 provided at the bottom of the main frame 100. Procedures, such as thyroidectomy, are performed.

When the procedure is completed, the adjustment handle 170 is rotated in the opposite direction as described above to reverse the adjustment shaft 180, and the upper spoke 150 and the connecting frame having its own weight in accordance with the reverse of the adjustment shaft 180 ( 130 is returned to its original position.

When the upper spokes 150 and the connecting frame 130 are returned, the upper spokes 150 and the lower spokes 160 are taken out from the inserted tunnel and then necessary post-operation is performed.

As described above, the retractor of the present invention ensures a stable and easy space for surgery during the procedure using an endoscope after resection, thereby providing convenience of surgery.

In addition, the retractor of the present invention has been exemplarily described to be used in the thyroid gland, but the present invention is not limited thereto, and the retractor may be easily used in other cervical regions such as the submandibular gland and lymph glands.

As described in detail above, the retractor according to the present invention is simple in structure and easy to operate, thereby improving convenience in use, as well as less damage to tissue at the surgical site, maximizing the convenience of surgery by securing sufficient operating space, and having a low price. Enables thyroid endoscopic surgery and microscopic ablation to provide the effect of minimizing cervical thoracic.
