Description

Technical Field

[0001] The utility model relates to the technical field of suction tubes, in particular to an endoscope-assisted suction tube. Background Art

[0002] During endoscopic surgery for EMR, ESD or other complex operations, since flushing, suction and many other operations are completed through the endoscope operation hole, when bleeding occurs and hemostasis and other treatments are required, the surgical field is unclear and it is difficult to perform surgical operations. The drainage effect of existing flushing and suction tubes is poor, and pus such as diseased tissue and cheesy substances can easily cause the suction tube to be blocked, and accumulated blood, fluid or other contaminants are difficult to discharge, making it impossible for the endoscope to reveal a good surgical field of view, which increases the difficulty and risk of the operation.

[0003] After searching, the Chinese patent document application number: 202122181526.2 discloses a disposable suction tube for use with an endoscope, including a suction tube body, a transparent cap and a suction control hole, the transparent cap is arranged on the upper side of the suction tube body; the suction control hole is installed on one side of the suction tube body. When the user blocks the suction control hole connected to the suction tube body with his fingers, the suction tube body can play a suction role and smoothly suck out the blood clot. On the contrary, when the suction control hole is in an open state, the suction effect of the suction tube body will disappear, thereby realizing intermittent suction operation through the suction control hole.

[0004] However, the above-mentioned disposable suction tube for endoscope still has the following defects:

[0005] When the user blocks the suction control hole connected to the suction tube body with a finger through the disposable suction tube for endoscope, the suction tube body can play a suction role and smoothly suck out the blood clot. On the contrary, when the suction control hole is in an open state, the suction function of the suction tube body disappears, thereby realizing intermittent suction operation through the suction control hole.

[0006] However, this device achieves intermittent suction operation through the suction control hole. Although it can meet certain surgical needs to a certain extent, it may also limit the continuity and stability of suction. It may not be suitable for situations that require continuous suction. Therefore, we need an endoscopically assisted suction tube to solve the above problems. Utility Model Content

[0025] 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.

[0026] See also Figure 1-4 The utility model provides a technical solution: an endoscope-assisted suction tube, comprising a tube body 1, a tip portion 4 is arranged at the upper end of the tube body 1, one end of the tip portion 4 is arranged obliquely, a tail portion 2 is connected to the lower end of the tube body 1, one end of the tail portion 2 is arranged as a plastic layer 3, a steel wire 11 is fitted on the inner wall of the tube body 1, a suction tube 12 is arranged inside the tube body 1, the interior of the suction tube 12 is a spiral structure, an endoscope tube 13 is also arranged inside the tube body 1, an endoscope cavity 14 for an endoscope to be inserted is opened inside the endoscope tube 13, the side wall of the endoscope cavity 14 is a tubular structure, the suction tube 12 is sleeved on the endoscope tube 13, a filling body 15 is fixedly arranged in the inner cavity of the tube body 1, and the filling body 15 is filled and installed in the gap around the suction tube 12 and the endoscope tube 13;

[0027] During use, the internal spiral structure of the suction tube 12 can increase the suction force of the suction tube 12, so that the suction tube 12 can be more effectively sucked out of the blood in the stomach. The inner wall of the tube body 1 is fitted with a steel wire 11, which enhances the structural strength of the tube body 1 and is not easily deformed or damaged during use. An endoscope cavity 14 is provided inside the endoscope tube 13 for the endoscope to be inserted, and the suction tube 12 is sleeved on the endoscope tube 13, so that the endoscope and the suction tube 12 can be used at the same time, and both endoscopic examination and suction operation can be performed at the same time, thereby improving the efficiency and accuracy of the operation. One end of the tip 4 is inclined, so that the suction tube 12 can be more easily inserted into the stomach, especially when there is a lot of blood or other liquid in the stomach, the inclined tip 4 can better adapt to the shape of the stomach, so that the suction operation is smoother. The filling body 15 is filled and installed in the gaps around the suction tube 12 and the endoscope tube 13, which can not only prevent blood or other liquids from seeping out of these gaps, but also enhance the stability between the suction tube 12 and the endoscope tube 13, and prevent them from moving relative to each other during use.

[0028] A through hole 9 is provided at the inclined portion of the tip portion 4, and the other end of the tip portion 4 is fixedly connected to the upper end of the tube body 1. The inclined tip portion 4 design, combined with the through hole 9, can reduce the resistance during the suction process. When the suction tube 12 enters the stomach, the inclined tip portion 4 can better adapt to the shape of the stomach wall, making the suction operation smoother and reducing the obstacles that may be encountered during the suction process.

[0029] One end of the tail portion 2 is open, and the plastic layer 3 is a soft polyvinyl chloride plastic layer. Polyvinyl chloride plastic is a commonly used medical plastic material with good durability and stability. It can maintain stable performance under a variety of environmental conditions, including acid and alkali resistance, high temperature resistance, etc. Therefore, using the soft polyvinyl chloride plastic layer 3 as the material of the suction tube 12 can ensure that the suction tube 12 has a long service life and stable performance during use.

[0030] A spiral drainage groove 7 for drainage is arranged on the outer side of the front end of the tube body 1, and a plurality of drainage ports 8 are arranged inside the drainage groove 7. The design of the spiral drainage groove 7 can increase the drainage area, so that more liquid or secretions can be drained into the suction tube 12, and the spiral structure of the drainage groove 7 can guide the liquid to flow along the groove, thereby reducing the residual liquid on the surface of the tube body 1 and improving the drainage efficiency.

[0031] The drainage port 8 is a guide surface with a larger outer end and a smaller inner end. Multiple drainage ports 8 are evenly installed on the drainage groove 7. The design of the drainage port 8 with a smaller inner end can prevent the occurrence of backflow to a certain extent. When negative pressure is generated inside the suction tube 12, the smaller drainage port 8 can better resist the external pressure, reduce the possibility of liquid backflow, and help maintain the stability and continuity of the suction process.

[0032] The surface of the tube body 1 is provided with a scale 6, which is fitted on the tube body 1. Through the scale 6 on the tube body 1, the doctor can adjust the insertion depth of the suction tube 12 more quickly, reducing the operation time and steps during the operation, helping to improve the operation efficiency, shorten the operation time, and reduce the patient's pain and discomfort.

[0033] The inner wall of the tube body 1 is provided with a hydrophilic coating 10, which is an acrylic resin. The hydrophilic coating 10 can make the inner wall of the tube body 1 smoother, reduce the residual liquid in the tube body 1, and help prevent the liquid from clogging the tube body 1 or breeding bacteria during the suction process, thereby improving the cleanliness and safety of the suction tube 12.

[0034] A cap 5 is provided at one end of the tip portion 4, and the cap 5 is transparent. The cap 5 can protect the tip portion 4 of the suction tube 12 from contamination and damage. During the operation, the tip portion 4 may come into contact with the patient's tissue or body fluids, and the cap 5 can serve as a barrier to reduce the direct impact of external factors on the tip portion 4.

[0035] The tube body 1 and the filling body 15 are an integral structure made of medical silicone. The filling body 15 is medical polyethylene. Medical silicone is known for its softness and elasticity, which enables the suction tube 12 to conform to the patient's anatomical structure during insertion and use, reducing discomfort. At the same time, medical polyethylene provides good durability and stability, ensuring that the suction tube 12 can maintain good performance after multiple uses or cleanings.

[0036] The steel wire 11 is arranged in a spiral shape and is wound and installed on the inner wall of the tube body 1. The spiral winding design of the steel wire 11 can significantly enhance the structural strength and rigidity of the tube body 1. This structure makes the tube body 1 less likely to deform or collapse when subjected to external force or pressure. The spiral winding of the steel wire 11 can effectively support the inner wall of the tube body 1 and prevent the tube body 1 from collapsing due to negative pressure during the suction process, which helps to keep the suction channel unobstructed and ensure the continuity and efficiency of the suction process.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
