Example 1
The embodiment 1 of the utility model provides a jejunum tube for stomach fistulization for carry the liquid food in to patient's jejunum, guarantee nutrition in the intestines, as shown in fig. 1, it includes body 1, and establish water pocket 2 and the fixed pressing plate 3 on body 1 respectively the cover.
As shown in fig. 2, a liquid food channel 11 and a waterway channel 12 are arranged in the tube body 1, an inlet of the waterway channel 12 is positioned at the outer end of the tube body 1, and an outlet thereof is positioned on the side wall of the tube body 1 and is butted with a water inlet of the water bag 2; the entrance of the liquid food channel 11 is located at the outer end of the tube body 1, the exit is located at the inner end of the tube body 1 extending into the jejunum 600, and the inner end of the tube body 1 is curled and is in a single pig tail shape.
The tube body 1 is made of a flexible material with self-recovery capability, preferably medical silica gel, the inner end of the tube body 1 is curled in a natural state, a single pigtail shape is kept, and the tube body can be unfolded into a linear state under the action of external force.
After adopting above-mentioned technical scheme, through 1 extension of body with the jejunum pipe, make its internal end can directly stretch into jejunum 600, liquid diet and medicine can directly be carried to jejunum 600, nutrition in the intestines has been guaranteed, still design the internal end of jejunum 600 pipe for pigtail formula structure simultaneously, make it be difficult to shift from jejunum 600, deviate from to in stomach cavity 400, thereby a series of adverse reactions that the food gathering arouses in stomach cavity 400 have been avoided, the treatment is guaranteed, patient's travelling comfort has been improved, and the security is higher.
Furthermore, the diameter of the jejunum 600 of the human body is generally 20mm-30mm, when the inner end of the tube body 1 is curled into a single pigtail shape, the maximum diameter of the pigtail structure is designed to be 25-35mm, so that the tube body is slightly attached to the inner wall of the jejunum 600, and a better displacement prevention effect is achieved.
Further, as shown in fig. 2, a guide wire lumen 13 is further provided in the tube body 1, the guide wire lumen 13 is semi-closed, an opening of the guide wire lumen 13 is located at the outer end of the tube body 1, and an inner cavity of the guide wire lumen extends to an outlet close to the liquid food channel 11.
The semi-closed guidewire lumen 13 is provided for the purpose of: when the guide wire 14 is inserted to the bottom of the guide wire lumen 13, the body inner end of the tube body 1 is unfolded from the single-pig tail shape to be in a straight line (as shown in fig. 3), so that the tube body 1 can be inserted into the gastric cavity 400 from the incision, after the body inner end of the tube body 1 is fed into the jejunum 600 with the assistance of a gastroscope, the guide wire 14 is withdrawn, and the body inner end is restored to the single-pig tail shape (as shown in fig. 4), so that the displacement and the falling-out of the body inner end from the jejunum 600 can be prevented.
Since the guide wire 14 needs to stretch the single pigtail-shaped inner end of the tube body 1 straight, the guide wire 14 itself needs to have a certain self-supporting force, and will not bend excessively under the elastic recovery force of the tube body 1, and the excessively thin guide wire 14 is difficult to satisfy the requirement, the guide wire 14 having an outer diameter of 3F is used here, and the inner diameter of the guide wire lumen 13 is preferably set to 1mm so that the guide wire 14 having an outer diameter of 3F can pass through.
Further, the inner wall of the guidewire lumen 13 is coated with a low coefficient of friction coating comprising barium sulfate.
The guide wire 14 is generally made of metal, and a large friction force exists when the metal and the silica gel slide relatively, so that the guide wire 14 has a large resistance when being inserted into or withdrawn from the tube body 1, and a problem that the tube body 1 put into the jejunum 600 is taken out when the guide wire 14 is withdrawn also can exist, meanwhile, in operation and after-operation examination, whether the tube body 1 is put in place needs to be observed through X-ray equipment, and the most main component of a general developer is barium sulfate. Therefore, the inner wall of the guide wire lumen 13 is preferably coated with a low friction coefficient coating containing barium sulfate, so that the friction between the guide wire 14 and the tube body 1 is greatly reduced, the development and observation are facilitated, and no lubricant or contrast agent needs to be input secondarily.
Further, in order to prevent the liquid food passage 11 communicating with the inside of the human body from being contaminated by the outside, a hole plug is provided at an inlet of the liquid food passage 11.
Meanwhile, hole plugs are arranged at the inlet of the waterway channel 12 and the opening of the guide wire lumen 13, so that the waterway channel 12 and the guide wire lumen 13 are prevented from being blocked by foreign matters.
The utility model discloses an operation process does:
(1) making incision on abdominal wall and stomach wall of required intubatton position of patient;
(2) a guide wire 14 is inserted from the opening of the guide wire lumen 13 until the guide wire is abutted against the bottom of the lumen, and the inner end of the single-pig-tail-shaped body 1 is straightened and unfolded under the action of the guide wire 14;
(3) inserting the tube body 1 into the gastric cavity 400 from the incision;
(4) with the assistance of a gastroscope, the internal end of the tube body 1 and the guide wire 14 in the tube body are simultaneously clamped by a clamp at the front end of the gastroscope, and the guide wire 14 and the internal end of the tube body 1 are conveyed into the jejunum 600 after passing through the duodenum 500;
(5) injecting water into the water bag 2 through the waterway channel 12 by using a syringe, taking down the syringe and plugging the inlet of the waterway channel 12 by using a hole plug after the water bag 2 is expanded to the maximum;
(6) the external end of the tube body 1 is slightly pulled outwards to ensure that the water sac 2 is tightly attached to the stomach wall and the stomach wall is tightly attached to the abdominal wall;
(7) the tube body 1 can be fixed after the fixed pressing plate 3 is tightly attached to the abdominal wall and sealed;
(8) the guide wire 14 is withdrawn, and the inner end of the tube body 1 in the jejunum 600 is restored to be in a single pig tail shape.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
