Description

Sealing port for endoscope

The present invention relates to a sealing port for an endoscope, and more particularly, to a sealing port for an endoscope that is applied to the introduction end of an endoscope retracting tool that induces insertion of various endoscopes including a ureteroscope into a human body to maintain an airtight state. .

In general, an endoscope is a term that refers to a device that is inserted into the body to observe the inside of the body for medical examination, and depending on the area to be examined, a ureteroscope, a bronchoscope, an esophagus, a gastroscope, a laparoscope, an anusoscope. There is a back, such as seeing with the naked eye, seeing images conveyed by fiberglass, and taking pictures.

For example, a ureteroscope is an equipment for surgical treatment such as removal of a ureteral stone or biopsy or removal of a ureteral tumor by entering a narrow ureter. Through the introduction of this equipment, instruments such as laser fibers and stone baskets are introduced into the ureteroscope to perform surgical treatment.

The ureteroscope maintains a certain level of hydraulic pressure by continuously introducing a solution (mainly physiological saline) or gas (mainly CO2) when performing surgery.

When a device such as a laser fiber or a stone basket is introduced through the introduction part of the ureteroscope using conventional plastic and rubber materials, the sealing degree is weak, and the solution backflows through the gap between the introduction part and the introduced device such as laser fiber. There is a problem that frequently occurs when it is buried in the body and eyes of the surgeon.

In this case, it interferes with the operation of the surgeon, and if the solution is contaminated, the risk of infection is high, and the hydraulic pressure is lowered due to reflux, causing various problems, such as deterioration of the surgical field of view. These problems tend to become more severe as the durability decreases as the procedure is performed.

Therefore, it is important that the seal port of the separator prevents the backflow of the solution while allowing the introduction of the ureteroscope or other instruments smoothly, and currently available instruments have such limitations.

Only when the expansion space is formed in this way, the hermetic means 12, which is a semi-solid gel, is supported while stably maintaining the shape at the correct position.

On the other hand, in the present invention, the port part 11 is provided with 2 to 4 paths on the upper surface, as shown in the accompanying drawings FIG. 6, and the

airtight means

121, 122, 123 are independent in each path. It is also preferable to be provided with.

In this way, when a plurality of

airtight means

121, 122, 123 are independently provided in a single port part 11, a plurality of surgical tools (T) are densely and intensively inserted into a specific area to perform surgery. In the situation, it is possible to make the operation of each of the surgical instruments (T) that are introduced without mutual interference.

On the other hand, in the present invention, the airtight means 12 is preferably located in the entire or part of the path through which the surgical tool (T) of the introduction part (2) or the port part (11) is drawn in/out.

Specifically, in the present invention, it is preferable to include 3 to 10% by weight of water-soluble chitosan based on the total weight of the hydrogel composition.

In order to secure the biological stability of biomedical materials, it is very important to prevent contamination from microorganisms. When a biomedical material contaminated with microorganisms comes into contact with the human body, it may cause fatal consequences depending on the condition of the patient, especially in the case of a patient undergoing surgery. Microorganisms prefer a state attached to the surface of a biomedical material rather than a state suspended in a liquid, and in the case of a hydrogel adhesive, there is a great risk of being exposed to contamination by microorganisms as described above. Factors involved in the adhesion of microorganisms include the type of microorganism, characteristics of the microorganism such as surface charge, chemical composition of the material, and characteristics of the material surface such as surface charge, hydrophobicity, roughness, and surface energy.

Chitosan is useful as a biomedical material because of its excellent biocompatibility, antibacterial properties, and bio-healing properties, and a polymer gel having excellent adhesion can be prepared by crosslinking an aqueous chitosan solution using a radiation crosslinking method. In addition, a hydrogel can be prepared by mixing chitosan with synthetic polymers such as polyvinyl lactam, polyvinylpyrrolidone, acrylic acid, acrylamide, etc., and then crosslinking with radiation. Therefore, it is usefully used in overall biomedical materials including artificial organ materials.
