Technical Field
The invention relates to a medical instrument, in particular to a guide tube special for laparoscopic sleeve gastrectomy.
Background
Laparoscopic sleeve gastrectomy (laparoscopic sleeve gastrectomy, LSG) is mainly used for weight loss and treatment of type 2 diabetes. The method of laparoscopic sleeve gastrectomy is to reserve gastric antrum above 2-6cm along the running direction of the greater curvature of the stomach by using a laparoscope, resect the majority of the stomach along the long axis of the stomach, resect the whole fundus of the stomach to make the residual stomach in a banana shape, and make the stomach form a small stomach pouch of about 150cc, which can hold about 4-5 ounces of food, the principle of laparoscopic sleeve gastrectomy is to reduce the stomach volume and reduce the hormone secretion that stimulates hunger sensation, thereby achieving the purpose of weight reduction. The laparoscopic sleeve gastrectomy has the advantages of not changing the physiological state of the gastrointestinal tract and not interfering with the normal digestion and absorption processes of food. Laparoscopic sleeve gastrectomy does not require the placement of foreign objects in the body. Compared with the laparoscopic gastric banding and gastric bypass, the laparoscopic sleeve gastrectomy has the advantages of small technical difficulty, no laparoscopic anastomosis operation, easy postoperative endoscopy, maintenance of the original continuity of the digestive tract and minimal influence on postoperative nutrition. The literature reports that the treatment of laparoscopic sleeve gastrectomy results in about 70% reduction of excess body weight 2 years after surgery, which is similar to the efficacy of gastric bypass surgery, but without complications such as anemia, osteoporosis, vitamin deficiency, etc. after gastric bypass surgery. The results of the 5-year follow-up study showed that re-enlargement of the stomach to be inflated rarely occurs after laparoscopic sleeve gastrectomy.
The laparoscopic sleeve gastrectomy has good treatment effect on type 2 diabetes, and is a weight-reducing and diabetes operation widely adopted in Europe at present. Studies have shown that patients receiving weight loss who have been treated with traditional medications alone can completely relieve blood glucose in type 2 diabetics compared to those who have been treated with diabetes. The average follow-up for 3 years, the cure rate of diabetes mellitus by sleeve gastrectomy is 80.9%. The laparoscopic sleeve gastrectomy has good effect on treating obese patients with type 2 diabetes, and blood glucose can be recovered to be normal before weight is reduced. The laparoscopic sleeve gastrectomy can reduce the use of medicines for diabetes, hypertension, hyperlipidemia and other complications while controlling blood sugar, and has different improvements in the aspects of overall health, emotional health, physical and social functions, pain relief, personal energy recovery and the like of patients.

Meanwhile, if only one lumen exists, side holes can be attached during suction, and the suction cannot be effectively performed; through the design, the round channel is connected with the negative pressure aspirator, when in use, holes are formed between the crescent channel and the round channel according to the requirements, liquid firstly enters the crescent channel, and then is sucked through the round channel, so that the problems can be avoided.
The circular pipeline is designed to be effectively matched and connected with the negative pressure aspirator, so that the requirements on materials of instruments in a conventional operating room are reduced. At the same time, the non-circular channel may be deformed or even closed during suction at negative pressure, so that it must be designed as an internal small circular channel, while the shape of the remaining cavity is determined by the position of the circular channel. In view of the manufacturing difficulty, the circular channel cavity is most suitable to be attached to the side wall of the whole large pipe, so that the remaining channel is crescent-shaped.
The working principle of the invention is as follows:
during laparoscopic sleeve gastrectomy, the guide tube 1 is inserted into the alimentary canal, gas and liquid in the alimentary canal enter the inner cavity of the guide tube from the exhaust holes 6-11 and the liquid suction holes 12-16 on the side wall of the guide tube 1, and are discharged out of the body and into the suction device through the other end of the crescent-shaped channel 4 in the inner cavity of the guide tube 1 and the circular channel 5 and the suction joint 3, and the resistance when the guide tube 1 is inserted into the alimentary canal is reduced at the same time; the guide head 2 at the front end of the guide tube 1 is a variable-diameter guide head, the diameter of the front end part of the guide head 2 is smaller than that of the guide tube 1, the resistance of the guide tube 1 when the guide tube 1 is inserted into the pylorus is reduced, the pylorus is prevented from being damaged, and the guide tube 1 is easy to guide when the guide tube 1 is inserted into the pylorus. In the laparoscopic sleeve gastrectomy operation process, the guide head 2 is supported in the pylorus to fix the front end part of the guide tube 1, the guide tube 1 is positioned at a specific proper position in the alimentary canal, and the guide tube 1 can be used as a shearing reference line for laparoscopic sleeve gastrectomy operation. The whole length of the outer wall of the guide tube 1 marks the distance value from the position of the scale point to the top point of the guide head 2 at the front end of the guide tube 1, and the insertion distance value of the guide tube 1 in the digestive tract can be directly read out, so that the length of the guide tube 1 in the digestive tract can be conveniently known, and the guide tube 1 can be conveniently positioned at a specific proper position in the digestive tract.
From the above description, it can be seen that the above embodiments of the present application achieve the following technical effects:
1. the guide tube is inserted into the pylorus with small resistance by adopting the variable-diameter guide head, thereby avoiding damaging the pylorus and being convenient to guide.
2. The diameter of the guide tube body is not limited by the diameter of the guide head and the diameter of the liquid channel, the diameter and the hardness of the guide tube body can be conveniently designed, and the moderate diameter size and the hardness of the guide tube body can be realized under the condition that the resistance is small when the guide tube is inserted into the pylorus, so that the guide tube body is conveniently positioned at a specific position in the laparoscopic sleeve gastrectomy operation to make a shearing reference line.
3. The inner cavity of the tube body is provided with an independent liquid channel, the diameter of the liquid channel in the inner cavity of the tube body is not limited with the diameter of the tube body, and the liquid channel with proper inner diameter can be selected, so that the suction pressure of liquid in the alimentary canal can be conveniently regulated, and the liquid in the stomach can be conveniently discharged in the operation process.
4. The whole length of the outer wall of the guide tube body marks the distance value from the position of the scale point to the top point of the guide head at the front end of the guide tube, so that the insertion distance value of the guide tube in the digestive tract can be conveniently and directly read, the length of the guide tube in the digestive tract can be conveniently known, and the guide tube can be conveniently positioned at a specific proper position in the digestive tract.
