Branch of Science Associated with the Invention

Engineering science related to single-incision video-assisted surgery equipment set with multiple entry-exit ports for medical instruments and gas tubes.

Background of related art or science

Figure 1 shows single-incision video-assisted surgery. In particular, umbilical incisions for surgery such as uterine tumor removals are aimed to minimize pain, accelerate healing and promote aesthetic beauty When the wounds heal, the scars will not be visible because they are hidden in the umbilical depression. At present, the use of rubber gloves as a medical instrument in surgery has been accepted and become a standard form. The Entry-exit Port Device 2 is in the form of a flexible rubber band. It is composed of the upper band and the lower band with equal diameters. The body of the upper band extending to the bottom band narrows into the middle band with a small diameter functioning as the entry-exit port for medical instruments installed on the abdomen around the umbilical area. The upper band is located on the abdomen of the patient, while the bottom band is located inside the patient's abdomen. Both bands together hold the abdominal wall in this position with the Entry-exit Port Device 2 attached to the bottom of the rubber gloves to provide the sealed area for surgery. All five fingers of the gloves point upward in the opposite direction rom the patient's abdomen.

The tips of all five fingers of the rubber gloves are arranged to provide entry for at least one piece of the medical instrument. In particular, medical instruments composed of at least three pieces are set to have different entry points through each finger to access the umbilical entry at the same central position.

The original invention as shown in Figure 1 has drawbacks in that the rubber gloves are implemented such that the index, ring and middle fingers are located closely together during actual usage. Therefore, when three medical instruments are inserted at the index, middle and ring fingers of the rubber gloves, and back and forth movements of the medical instruments are required during surgery, the three medical instruments will come into contact at the top and thereby obstruct surgery. Furthermore, the entry point devices for medical instruments have to be installed to the rubber gloves afterward, which is inconvenient and insecure. Another drawback is that when surgery requires gas to be inserted through the rubber gloves for delivery to the abdomen in order to expand the abdomen to increase space and provide visibility for surgery through the small incision in the abdomen, with the rubber gloves at the little finger and thumb acting as the gas release and refill points, respectively. The gas entry-exit ports are installed at the tips of the little finger and thumb for external gas tube connections. The gas entry-exit ports installed at the tips of the little finger and thumb cannot sufficiently support the gas pressure. In addition, the gas entry-exit ports have to be installed afterward, which is inconvenient and insecure. Additionally, the gas ports are located near the medical instrument ports, which obstructs and causes inconvenience. Furthermore, another drawback is that the bottom band of Entry-exit Port Device 2 in the form of a flexible band composed of the upper band and bottom band has a large diameter during actual usage. The unnecessarily large size of the aforementioned band causes it to be difficult to be pressed and contracted for insertion of the band through the umbilical entry.

The current invention has made corrections for the single-incision video-assisted surgery equipment set with multiple entry-exit ports for medical instruments and gas tubes for each port of the multiport structure to be spaced from one another other to prevent a number of medical instruments inserted into the multiport from hitting the top part during back and forth movements. Furthermore, the entry-exit ports of a number of different forms of medical instruments are installed permanently to the multiport tube to facilitate use.

Moreover, the gas entry and exit ports are situated on the horizontal plane on the opposite direction and not close to the Medical Instrument Entry Ports in order to space the aforementioned apart and provide convenience during surgery without obstructing external gas tube connection. It is not located near the Medical Instrument Entry Ports in order to separate locations and facilitate surgery without obstructions to the upper side. A number of gas entry-exit ports are installed permanently to the multiport tube to provide usage convenience.

Furthermore, Entry-exit Port Device 2 in the form of a flexible band is composed of the upper band and the lower band with unequal diameters. The lower band has a smaller diameter than the upper band to enable shrinkage for easy insertion of the lower band into the small single-incision.

Invention Characteristics and Objectives

The single-incision video-assisted surgery equipment set with multiple entry-exit ports for medical instruments and gas tubes with multiport tube structure has each port spaced apart to prevent a number of medical instruments inserted into the multiport tubes from hitting the top part as the medical instruments move back and forth during surgery. The entry-exit ports of a number of different types of medical instruments are permanently installed at the multiport tube in order to facilitate use. Meanwhile, the gas entry and exit ports are installed on a horizontal plane in the opposite direction and not close to the Medical Instrument Entry Ports in order to separate locations and facilitate surgery without obstructions and facilitate external gas tube connection and not close to the Medical Instrument Entry Ports in order to separate locations and facilitate surgery without obstruction to the upper part. A number of gas entry-exit ports are permanently installed at the multiport tube to facilitate such that entry-exit to Port Device 2 in the form of a flexible band composed of the upper and lower bands with unequal diameters where the lower band has a smaller diameter than the upper band to enable shrinkage for easy insertion of the lower band into the small single incision.

The objective of this invention is to provide a single-incision video-assisted surgery equipment set with multiple entry-exit ports for medical instruments and gas tubes specifically for use in single- incision video-assisted surgery, especially with Medical Instrument Entry Ports permanently installed on to the multiport tube to enable convenient use without subsequent installation, protection for a number of medical instruments moving back and forth during surgery from hitting the upper part and gas entry-exit tubes installed on the horizontal plane to enable convenience in external gas tube connection spaced away from Medical Instrument Entry Ports to separate locations and facilitate surgery without obstruction with gas entry-exit ports permanently installed on the multiport tube to provide effective pressure support and usage without requiring subsequent installation.
