Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a surgical anastomosis device for attachment to a patient after a surgical procedure.

There are various types of anastomosis devices that have been used in the past, which are attached to a stoma formed in the human body through surgery, but the one that is currently widely used is a skin-attached part that is attached around the patient's stoma. , a bag part for storing excrement, and the skin contact part is made to be sticky on the human body side and has a convex ring on the side opposite to the human body side, while the bag part has a convex ring on the skin contact part. It has a concave ring that can be fitted with a shaped ring and a bag part, and when in use, the bag part is connected in a so-called snap lock type by fitting the concave ring of the bag part to the convex ring of the skin contact part. It is fixed to the skin part, and after excretion, the bag part is removed from the skin part, and the bag part is washed and then reused. This type of anastomosis device has the advantages of being easy to operate, being economical as the pouch can be reused, and being able to change the direction of the pouch. When fitting the convex ring on the part and the concave ring on the pouch part, a certain amount of external pressure must be applied to securely lock the pouch.
The disadvantage is that it is extremely painful. In order to solve this problem, the convex ring of the skin contact part is attached to the main body of the skin contact part through a thin film or bellows so that it has flexibility, and the external pressure at the time of fitting is applied to the back side of the convex ring. There are commercially available devices that are supported by the hand to prevent abdominal pressure from being applied to the patient. Although this type of device certainly overcomes the above-mentioned disadvantages, it requires considerable force to engage the convex and concave rings, requires both hands, and It is necessary to check whether the lock is securely applied all around the circumference, the effective diameter of the opening is small, and it is not always easy to clean excrement attached to the bellows part, especially with bellows type ones. However, there are still some drawbacks such as not being able to use it properly, and the operability is not satisfactory.

The present invention aims to solve all of the problems of conventional anastomosis devices.

According to the present invention, this purpose is to include a skin contact part and a bag part, one of the skin contact part and the bag part is a female type double ring body, and the other is fitted into this female type double ring body. Each of them has a male type ring body which is adapted to be used as a pouch, and a female type double ring body or a male type ring body provided in the skin-contacting part is arranged so as to surround the stoma opening, and a male type ring body provided in the pouch part is arranged so as to surround the stoma opening. The male ring body or the female double ring body has a bag part on the opposite side from the skin contact part,
The male ring body has a groove and a sealing member arranged along its outer periphery, and the female double ring body has an inner ring and an outer ring, and a plurality of claw pieces provided inside the outer ring. This is achieved by being configured such that the inner ring can be inserted into and removed from the groove of the male ring body by passing through a side hole provided in the inner ring.

The outer ring of the female double ring body has a flexible claw piece that extends inward along its inner periphery and has an inward return force, and allows the outer ring to rotate relative to the inner ring. Accordingly, the claw pieces are configured to penetrate through the side holes of the inner ring and protrude to the inside of the inner ring, or move to the outside of the inner ring from the side holes of the inner ring, and as the outer ring rotates, The female double ring body can be configured to be inserted into and removed from the male ring body.
