Description

Laparoscopic surgical device {LAPAROSCOPIC SURGERY APPARATUS}

The present invention relates to a laparoscopic surgical device, and more particularly, to a laparoscopic surgical device for more rapid and stable surgery when performing operations on various organs within the abdominal cavity.

In general, a laparoscopic surgical device is for minimally invasive surgery, and is a device for accurately and safely performing operations such as cholecystectomy, prostate surgery, gastric resection, and tumor removal by inserting an instrument into the abdominal cavity through a small incision.

However, during cholecystectomy, one of the representative surgical operations, there are cases in which the biliary tract is damaged regardless of the operator's skill level. Injury to the gallbladder or biliary tract may also occur.

When the gallbladder or biliary tract is damaged in this way, invasive treatment or reoperation is required due to bile leakage or biliary stenosis, which leads to an increase in the patient's hospitalization period and treatment cost, and even death due to biliary damage. case can be brought.

Therefore, cholecystectomy, which is currently being performed, is performed through intraoperative cholangiography after surgically dissecting and confirming the anatomical structure of the biliary tract.

Cholangiography is usually near-infrared cholangiography, and a contrast medium such as indocyanine green is administered intravenously, and the indocyanine green metabolized in the liver contrasts the biliary tract, thereby determining the location of the biliary tract.

However, such cholangiography has a disadvantage in that a long time is required to selectively contrast the biliary tract in order to selectively contrast the biliary tract because the background signal of the liver is too bright in order to obtain a signal generated by a contrast agent by irradiating near-infrared rays.

5 is a view for explaining a method of performing cholecystectomy using the laparoscopic surgical device according to the present invention.

First, as shown in (a) of FIG. 5, in the laparoscopic surgical apparatus according to the present invention, the infusion tube 101 of the first module approaches the gallbladder by a medical staff, and then the infusion tube 101 enters the gallbladder. When contacted or injected, signals are generated by sensors included in the first sensor module 205a shown in FIG. 2 , and the generated signals are transmitted to the pressure controller 500 . At this time, although not shown, the generated signal may be signal-processed by the computing device and visually displayed on the display device 700 .

Then, as shown in (b) of FIG. 5, as the infusion tube 101 is injected into the gallbladder, the bile inside the gallbladder flows out. maintained under negative pressure). The pressure control unit 500 may be operated manually by a medical staff by recognizing the generated signal, but may be operated automatically according to the sensing signal of the first sensor module 205a. When the inside of the bile duct 103 is maintained at a negative pressure, the leaked bile is carried out of the abdominal cavity along the suction duct.

Then, as shown in (c) of FIG. 5, the infusion tube 101 is injected into the gallbladder, and the gallbladder is primarily removed by using the conjugate 103b disposed on the outer circumferential surface of the suction tube while maintaining the inside of the suction tube under negative pressure. Bind the perforated area. The zygote may be bound by a medical staff using a surgical instrument such as forceps. After binding the conjugate 103b, the medical staff injects a contrast agent such as ICG into the gallbladder through the injection tube 101.

Then, as shown in (d) of FIG. 5, after injecting a certain amount of contrast medium into the gallbladder, the infusion tube 101 is retracted from the gallbladder, and the perforated portion of the gallbladder generated as the infusion tube 101 is retracted is held with forceps. Secondary binding to the zygote 103b using the like. At this time, the marker 103c is positioned at the perforated site together with the zygote to mark the position, and accordingly, a certain amount of contrast medium is internalized in the gallbladder without leakage of bile or contrast medium.

After that, cholecystectomy is usually performed. For example, the gallbladder and the bile duct are irradiated with near-infrared rays to which the contrast agent reacts, and the location of the bile duct is identified using fluorescence generated as the gallbladder and the bile duct are irradiated, and then a necessary operation is performed.

As such, by directly injecting a contrast agent into a tissue such as the gallbladder using the laparoscopic surgical device according to the present invention, the exact position of the tissue can be identified, thereby reducing the operation time, and above all, the relationship between the tissue of the surgical target and other tissues can be reduced. As the distinction becomes clear, stable surgery can be performed.

The laparoscopic surgical apparatus according to the present invention can be used not only for cholecystectomy using the gallbladder as an object described in one embodiment of the present invention, but also for any case where it is necessary to locate an object using a contrast medium inside the abdominal cavity.

As described above, the preferred embodiments according to the present invention have been reviewed, and the fact that the present invention can be embodied in other specific forms without departing from the spirit or scope in addition to the above-described embodiments is a matter of ordinary knowledge in the art.
