Technical Field

The utility model relates to the technical field of medical auxiliary equipment, in particular to an endoscope-guided duodenal nutrient canal.

Background

Clinically, for patients with esophageal cancer, postoperative gastric cancer or food obstruction of late esophageal cancer, gastric cancer and the like, the feeding tube is often required to be placed below the pylorus, such as below the descending part of duodenum, under guidance of an endoscope. Compared with the nutrient tube which is placed in the stomach and below the descending part of the duodenum, the utility model can reduce the reflux of the nutrient solution when the patient is in the supine position, thereby reducing the stimulation of the nutrient solution to the esophagus, the anastomotic stoma of the stomach and the tumor wound surface. The gastrointestinal nutrition tube that uses at present is the similar cylindrical nutrition tube that the front end has the side opening, and this kind of nutrition tube is difficult more below wanting to place the duodenum descending part, often need tie up the end of a thread at the nutrition tube front end in the actual clinical work, presss from both sides the end of a thread through scope biopsy forceps, takes the nutrition tube to follow the scope and get into below the duodenum descending part together.

The disadvantages of the prior art include the following: firstly, the binding wires take time and energy, and the operation is complicated; in addition, the suture has poor skin affinity, stays in the descending part of the duodenum of the stomach of a human body for a long time, causes obvious discomfort for patients, also causes bacteria in the intestinal tract to gather in the descending part of the duodenum, has the possibility of causing the bacteria to enter the bile duct and the pancreatic duct through the countercurrent of the abdomen of the Vater kettle, and causes cholangitis and pancreatitis; in addition to the residue problem caused by suture guidance, the feeding tube is smooth at the front end, and is often carried out of the feeding tube into the stomach when the endoscope exits the duodenum, which easily causes placement failure.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides a duodenum nutrient canal under scope guide, including nutrition tube mouth of pipe 1, 1 front portion in nutrition tube mouth of pipe is equipped with stopcock 11, 1 tail end in nutrition tube mouth of pipe is equipped with regulation and control joint 22, regulation and control joint 22 transversely is equipped with regulation and control handle 23, 1 tail end in nutrition tube mouth of pipe is equipped with through the inside nutrition tube pipe 12 of regulation and control joint 22, nutrition tube pipe 12 end is equipped with nutrition tube head 13, nutrition tube head 13 upside is equipped with through-

hole

14, 14 upsides in through-hole are equipped with valve leaflet structure 2, valve leaflet structure 2 is equipped with the control channel 21 that extends to regulation and control joint 22 department along the outer wall of nutrition tube pipe 12.

The outer side of the valve leaflet structure 2 is provided with a medical polyurethane layer, a converging core 203 is arranged in the valve leaflet structure 2, a plurality of longitudinal converging nets 202 are outwards diverged from the converging core 203, the falling points diverged from the longitudinal converging nets 202 are the inner wall of the valve leaflet structure 2, and a transverse support net 201 is arranged at the falling points.

Specifically, the outer side of the valve leaf structure 2 is a medical polyurethane layer which is made of the same material as the material of the nutrition tube catheter 12, so that the valve leaf structure has good adaptability to the human body. When the nutrition tube enters a human body, the biopsy forceps are adopted to clamp the valve leaflet structure 2 to guide the nutrition tube to enter duodenum without being guided by binding wires, and the valve leaflet structure 2 plays a guiding role.

The transverse supporting net 201 and the longitudinal converging net 202 are made of titanium-nickel alloy, a hard plug 211 is arranged at the joint of the valve leaflet structure 2, a through hole 212 is formed in the hard plug 211, a control line 210 is arranged on the converging core 203, and the control line 210 extends into the regulating joint 22 through the through hole 212 and the control channel 21.

Furthermore, the titanium-nickel alloy is a memory alloy, and is in a binding state at normal temperature or low temperature before the valve leaflet structure 2 enters the human body, so that the valve leaflet structure 2 cannot bulge, and the tube head 13 of the nutrition tube can conveniently enter the human body. After entering human body, the memory alloy is unfolded along with the temperature change, so that the effect of preventing the displacement after the tube is placed can be achieved.

The regulating joint 22 is connected with the regulating handle 23 through a control line 210, the regulating handle 23 comprises a fishhook-shaped thumb retaining ring 231 and an index finger retaining ring 232 which is sleeved on the outer side of the thumb retaining ring 231, and the thumb retaining ring 231 is connected with the control line 210 inside the index finger retaining ring 232.

Furthermore, the design is that the nutrition tube needs to be taken out after being used for a plurality of time periods, and the valve leaf structure 2 is unfolded in the body, so that the fixation effect is strong and the nutrition tube is not easy to take out. Thus, the adjustment handle 23 is used to break the internal support structure of the leaflet structure 2. The leaflet structure 2 then becomes flat from bulging to collapsing for easy removal. Because the thumb retaining ring 231 and the forefinger retaining ring 232 in the control handle 23 can relatively displace, the control wires 210 can be pulled, the control wires 210 pass through the control joint 22 and simultaneously pull the control wires 210 in the two control channels 21, then the control wires 21 pass through the through holes 212 on the respective hard plugs 211, the tightening core 203 is pulled, and the tightening core 203 tightens the transverse support net 201 through the longitudinal tightening net 202.

The outer surface of the valve leaf structure 2 is provided with a granular anti-skid layer, so that the anti-skid performance of the valve leaf structure 2 can be enhanced.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
