[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Embodiment 1
[0021] Combination Figure 1-Figure 4 , an auxiliary intestinal dilation device, comprising a guide head 1 and a cylindrical tube 2, both left and right ends of the cylindrical tube 2 are fixedly provided with sealing partitions 5, and the two sealing partitions 5 isolate the inside of the cylindrical tube 2 into a closed environment; an air inlet is opened on the sealing partition 5, an air injection pipe 6 is fixedly provided on the inner wall of the air inlet, an air inlet pipe 9 is provided at one end of the air injection pipe 6, a control valve 7 is provided between the air inlet pipe 9 and the air injection pipe 6, a pressure gauge 8 is provided at one end of the air injection pipe 6, and the cylindrical tube 2 is provided with a row of foldable annular folds along the axial direction;
[0022] The cylindrical tube 2 is mainly made of medical silicone or polyurethane material. One end of the cylindrical tube 2 is fixedly connected to the guide head 1, and the other end of the cylindrical tube 2 is fixedly provided with a catheter 3. An endoscope 4 is arranged inside the catheter 3. One end of the endoscope 4 passes through two sealing partitions 5 in sequence and extends to the inside of the guide head 1. The air injection tube 6 is arranged inside the catheter 3. One end of the air injection tube 6 extends out of the catheter 3 and is connected with the air inlet pipe 9 through the control valve 7. The surfaces of the cylindrical tube 2 and the guide head 1 are coated with medical lubricant. The guide head 1 is arranged in a pointed shape, and the inside of the guide head 1 is hollow. The sealing partition 5 is made of a medical rubber sealing ring, and the catheter 3 is made of medical flexible material for protecting the endoscope 4 and the air injection tube 6.
[0023] Specifically, in this embodiment, the cylindrical tube 2 is inflated through the air inlet pipe 9, and the gas injection pipe 6 delivers gas to the cylindrical tube 2. The cylindrical tube 2 is made of a flexible material, and its surface is foldable annular folds, so that it can be easily inserted into the intestine in an uninflated state. After inflation, the cylindrical tube 2 unfolds to form a smooth expansion surface, which can achieve safe and gentle expansion of the intestine, reduce the patient's discomfort, and improve the safety and efficiency of the medical process; through the setting of the control valve 7, the user can adjust the inflation amount or deflate the cylindrical tube 2, and through the setting of the pressure gauge 8, the user can monitor the air pressure inside the cylindrical tube 2 to ensure safe use. The control valve 7 and the pressure gauge 8 jointly ensure the safety and effectiveness of the intestinal dilator during use, so that the doctor can perform precise operations according to the specific conditions and needs of the patient.

The guide head 1 is set in a pointed shape to facilitate better insertion into the intestine. After the cylindrical tube 2 is sent into the intestine, the intestine can be explored through the endoscope 4. When expansion is required, since sealing partitions 5 are provided at both ends of the cylindrical tube 2, the inside of the cylindrical tube 2 is a closed environment, and the cylindrical tube 2 is made of a flexible material, and its surface is foldable annular folds, so that it can be easily inserted into the intestine in an uninflated state. After that, the cylindrical tube 2 is inflated through the air inlet pipe 9, and the control valve 7 can adjust the inflation amount and deflation. The pressure gauge 8 is convenient for monitoring the air pressure inside the cylindrical tube 2 to ensure safe use. The gas is transported to the gas injection pipe 6 and injected into the cylindrical tube 2. After inflation, the cylindrical tube 2 unfolds to form a smooth expansion surface, which can achieve safe and gentle expansion of the intestine, reduce the patient's discomfort, and facilitate improving the safety and efficiency of the medical process.
