Description

The present invention relates to an anastomosis instrument, and more particularly, to a sleeve-type fixation anastomosis ring used for surgery of the stomach, intestine, esophagus, gallbladder and the like.

Surgery for the intestine and gallbladder is a normal operation, especially after total gastrectomy, and an anastomosis of the intestine and esophagus must be performed. However, after anastomosis using a conventional anastomosis device, complications such as postoperative anastomotic suture failure, anastomotic stenosis, regurgitation, and affecting the passage of food appear. The cost of anastomosis instruments is high.

Currently used stapler-type tubular anastomosis devices (eg, CDH25 anastomosis device manufactured by Johnson & Johnson, USA) are turned over with a distant intestinal tract and then fixed using a double row nail. It forms into a stenotic ring that cannot be expanded or contracted after adhesion, and causes complications such as postoperative anastomotic suture failure, anastomotic stenosis, reflux, and affecting the passage of food.

In addition, the Chinese patent of CN1036898Y provides an elastic attachment ring for fastening to be used in the esophageal gastric cavity, and the fastening ring to be used in the esophageal gastric cavity is the esophagus and stomach after excision of esophageal cancer or cardia cancer. Suitable for use in anastomosis surgery. The attachment ring includes a main body, a handle, a ring structure, and a support tube structure, and the support tube structure and the ring structure work synchronously. After performing esophagogastric anastomosis using this instrument, there is no suture material left in the anastomosis, the anastomosis is tightly coupled, and situations such as anastomotic suture failure and anastomotic stenosis may occur. It can be effectively prevented, the operation of the instrument is simple, easy to master and saves time.

The Applicant provides a sleeve-type intestinal anastomosis ring which is locked in the CN 101327142 patent, and includes an inner ring, an outer ring and an elastic ring, and an outer ring shape at the bottom of the inner ring. A bowl-shaped groove is installed, an annular groove is installed at the top of the outward ring-shaped bowl-shaped groove, and a back-side annular bowl is installed at the bottom of the outer ring. An annulus is connected to an outward ring-shaped groove, and an annular groove is also installed in the reverse-side ring-shaped groove, and the elastic ring is installed between the two ring-shaped grooves. The ring-shaped hook locks with the outward-shaped ring-shaped groove at the bottom of the inner ring.

The present applicant provides a sleeve-type intestinal anastomosis ring that is fixed with a rubber ring lock in the CN 10123987 patent, and includes an inner ring, an outer ring, and an elastic ring, and a lower part of the inner ring. Has a ring-shaped groove facing backwards, a ring-shaped ridge is installed on the back side of the inner ring, an outward projecting ring is installed on the lower part of the outer ring, and at least two hooks are provided on the back side of the lower part of the outer ring. The hook that is installed and installed on the back side of the lower part of the outer ring locks with the ring cage installed on the back side of the inner ring.

The technical means described in the two patents of the present applicant do not cause any postoperative anastomotic suture failure, no anastomotic stenosis, little backflow, smooth passage of food, and a foreign body in the anastomosis. However, the operation cost is long, the operation process is complicated, and the anastomosis fixation effect and the medical cost are still not satisfactory.

The purpose of the present invention is to overcome the problem that the operation time that existed in the disclosed technical means is long, the operation process is complicated, and the anastomosis fixation effect and medical costs are still not fully understood, and the structure is simple Shorter operation time, easier operation process, better anastomosis results, higher safety and reliability, lower medical costs, and often used for surgery such as intestine, stomach, esophagus and gallbladder A sleeve-type fixation anastomosis ring is provided.

The present invention adopts the following technical means,
In the sleeve type fixing anastomosis ring, an inner ring and an outer ring are installed, and in order to be inserted into the back of the outer ring, the inner ring extends downward to form a connection ring. An arc-shaped groove is formed between the bottoms, a protruding ring is installed on the back side of the bottom of the outer ring, and the protruding ring is installed by anastomosing the arc-shaped groove.

In the most preferred embodiment, the bottom of the arcuate groove is planar.

In the most preferred embodiment, the inner ring is an inner ring made of a hard material, for example, an inner ring made of hard plastic, and the height of the inner ring is 3 to 6 mm.

In the most preferred embodiment, the outer ring is an elastic outer ring, such as a rubber ring, a silica gel ring, or a synthetic resin ring, and the rubber ring includes, for example, a nitrile / butadiene / rubber ring. Is 3 to 6 mm in height.

In the sleeve type fixing anastomosis ring of the present invention, an inner ring and an outer ring are installed, and the inner ring extends downward to form a connection ring for insertion into the back of the outer ring. An arc-shaped groove is formed between the bottom of the inner ring and the bottom of the inner ring, the bottom of the arc-shaped groove is flat, a protruding ring is installed on the back side of the bottom of the outer ring, and the protruding ring is installed by anastomosing the arc-shaped groove Therefore, in the present invention, the two rings are sleeved and anastomosed and locked. And since the inner ring adopts a hard material and the outer ring adopts an elastic material, the outer ring can be turned over arbitrarily, the protruding ring of the elastic outer ring and the arc-shaped groove of the inner ring are closely anastomosed, The inner ring and the outer ring have higher bonding reliability, better anastomosis effect, higher safety and reliability, shorter operation time, easier operation process and lower medical cost.
