Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical article, and particularly to treating a patient who is pathological and fat by sandwiching the stomach into a smaller gastric pouch and reducing food. Related to the partitioning clamp.

[0002]

2. Description of the Related Art For patients who are pathological and fat (humans whose body weight exceeds 100% of the standard weight), the general principle is not effective in reducing the weight. These patients are always faced with problems in health, life, and social issues and must be actively assisted by medical technology. One such technique is surgery. Modern surgical practices reduce the absorption capacity of the digestive path. In the field of medicine, gastrointestinal bypass surgery and gastric partition surgery have come before and after. From 1960 to 1970, jejunum and ileum bypass were adopted, that is, the upper small intestine was directly connected to the end of the small intestine. Then, the digested food will reach the large intestine rapidly and the chance of absorption will be greatly reduced. However, due to the reduction of the absorption area, the absorption of nutrients also became a problem, leading to malnutrition, and such a method was finally abandoned. After that, a stomach partition surgery is recommended. Its main purpose is to reduce the volume of the stomach and forcibly reduce food, thereby fulfilling the purpose of weight loss. In the conventional gastric partition surgery, for example, as shown in FIG. 1, first, an automatic gastrointestinal match gun is used to make a hole in the stomach wall. Then 4
With a row of nails 2 approximately 50 ml of gastric pouch 3 along the length of the stomach
Partition. The size of the opening 4 is about 10 mm. Later, position with Core-Tex or Marlex 5 tape.
The main principle is the newly formed gastric pouch, which controls the feed of food and, at the same time, the outlet caliber of the new gastric pouch, which controls gastric emptying. The outlet is simultaneously restricted by the artificial peritoneal band, thus preventing the outlet expansion of the gastric pouch. Not only does it prevent food from passing quickly through its exits, it not only has the effect of losing weight and endurance, but it also prevents eating large amounts of food.

Unfortunately, gastric partition surgery takes a long time, the abdominal wound is large, the patient's bleeding is more and it hurts, the stomach guide tube is left for about a few days, and the wound is less likely to leave. However, it has the drawback of being easily transmitted. If it becomes terrible, if you have a stomach partition surgery, there is no recovery, so you must evaluate it carefully before surgery, and be careful and care after it.

[0004]

SUMMARY OF THE INVENTION In view of the above, the present invention solves the drawbacks of the conventional gastric partition surgery such as no reversion, long operation time, risk of leakage of wound, bleeding and infection. , An object of the present invention is to provide a stomach partitioning clamp. The physical partitioning of the stomach serves the purpose of reducing food and weight loss. The clamp divides the stomach according to the operation of the laparoscope, so the operation time is short, the abdominal wound is small, the pain is reduced, the risk of infection is low, and the day of the operation,
It has the advantages of being able to eat, leave the hospital, and have a considerable amount of blood circulated in the stomach that is clamped in the clamp. The gastric wall sandwiched between the clamps has poor blood circulation and effectively avoids the phenomenon of necrosis or deterioration, resulting in a low yield. Also,
There is also a reversion property that the clamp is removed at any time to restore the structure of the stomach.

[0005]

SUMMARY OF THE INVENTION In accordance with the present invention, the gastric partitioning clamp provided comprises primarily two scissor flakes. Each of the scissors has an elongated shape, and both ends are provided with a connecting structure. The binding structure combines two scissors flakes in a straight-line manner, sandwiching the upper gastric region of the human body like a ramp. Then, a gastric pouch is formed in the upper stomach of the clamp. A bridge portion is formed by bending like an arc at a position near the center of the two scissors flakes. The corresponding bridges of the two scissors flakes form the outlet of the gastric pouch in the stomach.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A plurality of embodiments of the present invention will be described below with reference to the drawings. First, as shown in FIGS. 2 to 5, the gastric clamping 10 ″ according to the first embodiment of the present invention is mainly composed of two scissors flakes 2.
Combine 0 and 20 'so that they face each other. It is made of stainless steel material for entering the human body. The scissors flakes 20, 20 'become elongated flakes. The corners are cut off and processed like wrapping. Both ends of the scissors thin pieces 20 and 20 'are provided with a coupling structure, respectively, and the stomach portion 40 is sandwiched between the two pieces 20 and 20'. In this embodiment, the joint structure is provided with long grooves 21 and 21 'on both sides of the two scissors flakes 20 and 20' so as to extend from a position near the end to the top and the bottom, respectively.
Through holes 22 and 22 'are formed in the upper and lower portions of the two corresponding long grooves 21 and 21', respectively. Two scissors flakes 2
The corresponding long grooves 22, 22 'of 0, 20' are passed, wound or tied with the steel wire 30. Note that the steel wire 30 is housed in the long grooves 21, 21 '.

The bridge portions 23, 23 'are formed by bending the two scissor thin pieces 20, 20' toward the center so as to be bent in an arc shape, and the two scissor thin pieces 20, 20 'are connected to each other. The first clamp stage 24, 24 'and the second clamp stage 25, 25' are divided. The first and second clamp steps 24, 24 '25, 25' provide rough surfaces on corresponding sides of the stomach 40. Also, scissors flakes 20, 2
0'is the number of auxiliary positioning holes 26, 26 'so that they are evenly spaced in the vicinity of one long side.
Is penetrated.

The scissors flakes 20, 20 'each have a thickness of about 0.
The thickness is 3 cm, the width is about 1 cm, and the total length is about 15 cm. The length of the breezes 23, 23 'is 4 cm
Then, the most protruding part is from the side of the scissors flakes 20, 20 ',
About 0.5 cm away. The length of the first clamp stage 24, 24 'is 6 cm and the length of the second clamp stage 25, 25' is 5 cm.
cm. The lengths, heights and thicknesses described above can be varied according to needs during manufacture, and suitable clamps 10, 10 'can be selected for different stomachs.

As shown in FIGS. 5 to 9, when the structure of the first embodiment is applied to a gastric partition surgery, all the precautions should be followed except for the assistance of laparoscopic instruments and techniques. (Since it is within the technical scope of surgery and is not the key point of the present invention, detailed description thereof will be omitted.)

First, the rough surfaces of the two scissors flakes 20 and 20 'are made to face each other. Corresponding through hole 22,
22 'is passed, wound or tied with a steel wire 30. Then, the clamp 10 is inserted into the abdominal cavity with a laparoscopic instrument. The rough surface of the clamp 10 is brought into contact with the stomach wall and the upper area of the stomach 40 is attached, like a ramp,
By isolating the upper part of 0, about 50 ml of gastric pouch 4
1 comes out. The two corresponding bridge portions 23, 23 'of the clamp 10 form the outlet 42 of the gastric pouch. By the way, through holes 22, 22 'corresponding to the other end of the clamp 10
Then, the steel wire 30 is passed through, wound, or tied.
At each end of the clamp 10, two scissors flakes 2 are provided to isolate the gastric pouch 41 when tied with a steel wire 30.
Between 0 and 20 ', the contact and closure thickness of the anterior and posterior stomach wall must be maintained. As a result, the blood flow on the stomach wall is not blocked even when the clamp 10 is sandwiched. Clamp 10
The contact between the rough surface of the and the stomach wall effectively avoids the displacement phenomenon. The doctor who performs the surgery uses the surgical sewing wire 31.
Then, the clamp 10 is positioned on the stomach wall by passing through the auxiliary positioning holes 26, 26 'and sewing with the outer surface of the anterior stomach wall.

After partitioning the stomach, a small amount of food enters the gastric pouch 41 through the esophagus 43, is discharged from the gastric pouch outlet 42 into the lower half of the stomach, and enters the duodenum 44. Therefore, it serves the purpose of reducing the volume of the stomach, reducing the amount of food consumed by patients who are overweight due to the condition, and reducing the weight.

As shown in FIGS. 10 and 11, in accordance with the present invention, an ideal second embodiment of the clamp 10 'has first and second clamp stages 24, 2 at positions corresponding to the sides of the stomach wall.
4 ', 25, 25' are processed like a wave groove. 12
And according to the invention, as shown in FIG.
An ideal third embodiment of 0'is the first and second clamp stages 2
How many through holes 28, 2 are provided in 4, 24 ', 25, 25'
Install 8 '. Since the clamps 10 ′ and 10 ″ of the ideal second and third embodiments are sandwiched in the stomach region at intervals, necrosis or deterioration of the stomach wall can be prevented more effectively.

Compared with the conventional gastric partitioning technique described in the background of the present invention, the conventional gastric partitioning technique makes the stomach part a destructive partition and cannot be recovered after the conventional procedure. In contrast, the present invention allows the stomach to be a physical partition so that the clamp can be removed from the stomach in the future. Further, since the clamp of the present invention performs the gastric partitioning technique in accordance with the laparoscopic instrument, the operation time is short (about 20 minutes), the abdominal wound is small, the amount of bleeding is small, and the painful feeling is reduced. There is less risk of infection, there is no risk of leakage of wounds with conventional gastric partition surgery
On the day of surgery, there are advantages such as meals and discharge. Also, instead of having the prior art of gastric partitioning make the stomach wall destructive, the present invention allows the clamp to:
In the sandwiched stomach part, the front and back stomach walls are closed like physical so that the blood circulation of the stomach wall is maintained, and because of being clamped, the blood circulation of the stomach wall is poor and necrosis occurs. Or, it effectively avoids the phenomenon that becomes worse, and lowers the frequency.
