Description

Laparoscopic Surgery Apparatus {APPRATUS FOR LAPAROSCPOIC SURGERY}

The present invention relates to a laparoscopic surgery apparatus, and more particularly, to a laparoscopic surgery apparatus is applied to the forceps portion.

Laparoscopic surgery means surgery without laparotomy, by inserting an endoscope into the affected part to observe the affected part. For laparoscopic surgery, a laparoscopic surgery apparatus capable of performing an operation such as incision, hemostasis, or suture of the affected part through a narrow hole formed in the human skin is needed.

The laparoscopic surgical device may include a tip for performing an operation such as incision, hemostasis, or suture on the affected part at one end. The tip may be formed in various shapes such as tong shape or ring shape according to the type of procedure.
Laparoscopic surgery apparatus may have a shape including a plurality of tips, handles for driving the tip, etc., the structure or shape thereof is disclosed in Korea Patent Registration No. 10-1098199, Korean Patent Registration No. 10-1091412 It is.
Dislocations may be applied to the tip of the laparoscopic surgery device for ease of surgery on the affected area. The method of applying a potential to a tip includes a method of applying a potential of a single pole and a method of applying a potential of different polarities to a pair of tips, respectively. The method of applying a unipolar potential to the tip is to attach a counterplate to the patient's skin and apply only one pole to the tip to allow current to flow through the entire body of the patient. The method of applying a potential of different polarities to a pair of tips is to apply a different potential to a pair of insulated tips so that a current flows only in a necessary part, thereby giving a small burden to the patient's body. to be.

However, when the operation is applied by applying a potential to the tip of the laparoscopic surgery apparatus, the float having the polarity of the surgical site may be attached to the tip of the opposite polarity. If the float adheres to the tip, the resistance between the tips, or between the tip and the counterplate increases, preventing current from flowing well, thus increasing the time required for surgery. Increasing the time of operation can seriously threaten patient safety.

The problem to be solved by the present invention is to provide a laparoscopic surgical device that can alleviate the adhesion of the float.

The objects of the present invention are not limited to the above-mentioned technical problems, and other technical problems not mentioned will be clearly understood by those skilled in the art from the following description.

Hereinafter, with reference to the accompanying drawings will be described embodiments of the present invention.

1 is a side view of a laparoscopic surgery apparatus according to an embodiment of the present invention.

Referring to FIG. 1, the laparoscopic surgery apparatus 1000 includes a forceps unit 100, a grip control unit 300, and a potential switch 500.

The forceps part 100 may be inserted into the body to perform an operation on the affected part. The tongs unit 100 may be formed in a tongs shape to hold or place a desired portion, and the operation of the tongs unit 100 may be controlled by an operation of the grip control unit 300.

The tongs unit 110 includes a first grip 110 and a second grip 120. The distance between the end of the first grip 110 and the second grip 120 is adjusted by the operation of the grip control unit 300 to hold or place a desired portion between the first grip 110 and the second grip 120. Can be. The first grip 110 and the second grip 120 may be formed of a conductive material so that a potential is applied and a current flows. Since the first grip 110 and the second grip 120 are inserted into the human body, the first grip 110 and the second grip 120 may be formed of a conductive material resistant to corrosion in consideration of hygiene. For example, the first grip 110 and the second grip 120 may be formed of a metal such as titanium alloy or stainless steel, but are not limited thereto.

A potential of different polarities may be applied to the first grip 110 and the second grip 120. For example, the potential of the (+) pole may be applied to the first grip 110, and the potential of the (−) pole may be applied to the second grip 120, and vice versa. By applying potentials of different polarities to the first grip 110 and the second grip 120, the forceps 100 may perform operations such as hemostasis, sutures, and incisions.

Flow and cauterize. Tissue of the cauterized affected area is destroyed, and through this, the laparoscopic surgery apparatus 1000 may perform operations such as stopping bleeding of blood vessels, or cutting abdominal adipose tissue during laparotomy.

Polarities of the potentials applied to the first grip 110 and the second grip 120 may be reversed. If the potential of different polarities is applied to the first grip 110 and the second grip 120 during surgery, the floating part of the polarized part is adhered to the grip of the opposite polarity so that the first grip 110 and the second grip 120 are attached. Increasing the resistance between the 120 prevents the current from flowing, which effectively prevents surgery such as hemostasis, sutures, or incisions, resulting in long surgical times. When the polarity of the potential applied to the first grip 110 and the second grip 120 is reversed, the polarized floating material attracted to the grip on one side is attracted to the grip on the other side, thereby suppressing intensive adhesion of the floating material. can do. Therefore, an increase in resistance between the first grip 110 and the second grip 120 due to the adhesion of the float can be reduced. This can improve the safety of the patient by reducing the operating time.
