Description

Technical Field

[0001] This invention relates to endoscopic catheters that perform many functions such as flushing, suction, air injection, smoke extraction, and instrument insertion. Background Technology

[0002] In various clinical departments, direct observation and treatment within body cavities are performed for the purpose of diagnosis, determining treatment outcomes, and deciding on treatment strategies for various pathological conditions. These all require endoscopic methods. However, using existing endoscopic instrument channels for treatment presents challenges in sterilizing these channels, resulting in unsatisfactory sterilization and a high risk of cross-infection.

[0003] Currently used endoscopic instrument channels and aspiration catheters are integrated with the endoscope and located inside, making them impossible to assemble or disassemble freely. During use, the instrument channels and aspiration catheters become contaminated with mucus or tissue, making cleaning and disinfection difficult and ineffective. Furthermore, if the catheter is damaged or blocked due to accidental aspiration of tissue, it cannot be used again. Each time such a problem occurs, the endoscope must be replaced, resulting in significant risks and increased instrument costs. Summary of the Invention

[0004] The problem that the invention aims to solve The purpose of this invention is to provide an external endoscopic catheter that can perform many functions such as flushing, suction, air injection, smoke extraction, and instrument insertion.

[0005] Methods for solving problems The present invention provides an external endoscope catheter with a buckle on one side. There is more than one buckle. The buckle can be fixed to the outside of the endoscope or removed from the endoscope.

[0006] In one embodiment, the endoscope is a flexible endoscope.

[0007] In one embodiment, the catheter described above can be a single-lumen, single-head catheter ( Figure 1 ), single-chamber multi-head ( Figure 2 It can also be multi-cavity and multi-head ( ), Figure 3 The term "single-lumen single-head" refers to a single catheter with one lumen, where the single-lumen catheter is connected to a single connector. The term "single-lumen multi-head" refers to multiple connectors sharing a single-lumen catheter. The term "multi-lumen multi-head" refers to a single catheter with multiple lumens, where each lumen is connected to a separate connector.

[0008] In one embodiment, the catheter lumen also includes an anti-deformation spring coil.

[0009] Invention Effects The external endoscopic catheter of this invention is secured to the outside of the endoscope using multiple clips. The catheter lumen employs an anti-deformation spring coil design to prevent bending or deformation of the catheter lumen during endoscope operation, allowing for free assembly and disassembly. The catheter is installed when using the endoscope for irrigation, suction, air inflator, or fumigation, and removed when not performing these functions. In addition to the above functions, the external endoscopic catheter of this invention can also perform instrument insertion. External instruments are inserted through the catheter to perform therapeutic effects such as incision, cauterization, coagulation, and hemostasis. Thus, the external endoscopic catheter of this invention can perform many functions, including irrigation, suction, air inflator, fumigation, and instrument insertion. Attached Figure Description

[0013] Figure 4 This is a schematic diagram showing the combination of the endoscope and catheter of the present invention. Detailed Implementation

[0014] Figure 1 The catheter 1 of the present invention shown has a plurality of snap fasteners 2 on one side.

[0015] In this manual, a catheter refers to a hollow, flexible tube used in the medical field that can be inserted into the lumen of the digestive tract, urinary tract, or abdominal cavity for purposes such as flushing, suction, inflating, fume extraction, instrument insertion, injection of medications or contrast agents, etc.

[0016] There are no particular limitations on the luminal organs that can be included; for example, they can be the bronchi, esophagus, stomach, small intestine, large intestine, vagina, bladder, thoracic cavity, abdominal cavity, etc.

[0017] The catheter of the present invention has a catheter cavity 3, a snap fastener 2, and a connector 4. The parts can be integrally formed or connected with appropriate connectors.

[0018] In this instruction manual, "endoscope" refers to a flexible medical endoscope. Examples of flexible endoscopes include nasal endoscopes, urethral endoscopes, ureteroscopes, bronchoscopes, upper digestive tract endoscopes (stomach, etc.), small bowel endoscopes, and large bowel endoscopes. The appropriate size catheter should be selected based on the target endoscope.

[0019] The catheter of the present invention has a snap fastener, the snap fastener being selected in an appropriate size according to the target endoscope, and there are multiple snap fasteners.

[0020] There are no particular restrictions on the shape of the buckle, but it is preferred to be round or oval.

[0021] The catheter of this invention is installed when using an endoscope for flushing, suction, air injection, smoke extraction, and instrument removal, and is removed when using an endoscope without performing these procedures.

[0022] The connector of the catheter of the present invention is connected to the supply source or receiver as needed through flushing, draining or aspiration units. External instruments enter through the catheter connector to exert therapeutic effects, such as cutting, cauterizing, coagulation, hemostasis, etc.

[0023] There are no particular restrictions on the shape of the connector, but a trumpet shape or a circle is preferred.

[0024] The external endoscopic catheter of this invention can be flexibly combined with or separated from the endoscope via multiple clips, enabling functions such as flushing, aspiration, air injection, fumigation, or assisted instrumental treatment of the lumen being treated. This invention integrates the functions of multiple catheters previously integrated inside the endoscope into a single external catheter, reducing cross-infection issues caused by catheter sterilization problems and increased usage costs due to catheter damage.
