Description

Technical Field

[0001] This utility model relates to the field of intestinal examination technology, specifically to a deformable intestinal examination and treatment tool. Background Technology

[0002] Traditional intestinal examination techniques mainly include X-ray examination and colonoscopy. X-ray examination can directly observe the inside of the intestines, while colonoscopy allows for direct visualization of the intestines.

[0003] Chinese patent CN217525079U discloses a novel colonoscopy probe, comprising a colonoscopy insertion tube and a battery. A push column is located on the left side of the insertion tube, and a detection component for probing the intestine is mounted on the left side of the push column. The detection component includes a rigid probe, a heating wire, and a camera. The camera is mounted on the outer surface of the rigid probe, and the heating wire is located on the inner surface of the rigid probe. The battery is embedded on the right side of the front end surface of the push column. A water injection hole and a jet nozzle are arranged sequentially from top to bottom on the left side of the push column. A lighting lamp is connected around the outer perimeter of the middle part of the push column. However, this device still has the following problems during use:

[0004] When examining the intestines, the colonoscope moves the cannula inside the intestines. However, the power for the cannula to bend comes from the bending of the lens of the colonoscope, which makes the lens of the colonoscope prone to damage after prolonged use.

[0005] Based on this, the present invention designs a deformable intestinal examination and treatment tool to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a deformable intestinal examination and treatment tool.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A deformable intestinal examination and treatment tool includes an inner tube and an outer tube, and also includes a convex membrane, a drug delivery tube, a balloon tube, and a fiberscope;

[0009] The inner tube is fitted inside the outer tube, and the right ends of both the inner and outer tubes are closed. A convex membrane is fixedly installed on the right end of the inner tube, and a fiber optic lens is inserted inside the inner tube.

[0010] Multiple drug delivery tubes are fixedly installed on the outer wall of the outer tube, and the multiple drug delivery tubes are distributed in a circumferential array with equal spacing on the outer wall of the outer tube;

[0011] Multiple airbag tubes are fixedly installed on the outer wall of the right end of the outer tube, and the multiple airbag tubes are distributed in a circumferential array at equal intervals on the outer wall of the outer tube;

[0012] The internal region of the inner tube constitutes the core cavity;

[0013] The area between the inner tube and the outer tube constitutes a suction cavity, and the right end of the suction cavity is a closed end;

[0014] The internal regions of the multiple drug delivery tubes constitute a drug delivery cavity;

[0015] Multiple airbag tubes together form a deformable layer.

[0016] Furthermore, the drug delivery tube and the balloon tube are spaced apart on the outer wall of the outer tube.

[0017] Furthermore, the inner tube, outer tube, and drug delivery tube are all made of waterproof soft silicone material.

[0018] Furthermore, the right end of the suction cavity is provided with multiple suction holes, and the multiple suction holes are distributed in a circumferential array at equal intervals on the right end face of the suction cavity.

[0019] Furthermore, a lubricating layer is provided at the outer end of the outer tube.

[0020] Furthermore, the right end of the drug delivery tube is provided with multiple drug delivery holes.

[0021] Furthermore, the multiple drug delivery holes are arranged in a linear array with equal spacing on the drug delivery tube.

[0022] Furthermore, the airbag tube is composed of multiple airbags, and the multiple airbags in each airbag tube are interconnected.

[0023] Furthermore, the convex membrane is made of transparent soft rubber material and is tightly connected to the left end of the inner tube by a waterproof sealing ring;

[0024] Furthermore, the right ends of the inner and outer tubes are provided with multi-stage telescopic structures.

[0025] Compared with the prior art, the advantages of this utility model are as follows:

[0026] In its initial state, the deformable layers are all inflated, keeping the inner and outer tubes vertical. This facilitates the insertion of the tool into the patient's intestines by medical personnel, allowing for observation of the intestinal tract via fiberoptic endoscope. When the tool encounters an obstruction in the intestine, the suction port in the suction chamber removes the obstruction and also suctions intestinal fluid. When a bend is needed, deflation of the corresponding balloon tube alters its expansion and rigidity, causing the right end of the outer tube to bend. Combined with the movement of the fiberoptic endoscope lens, this makes the tool easier to bend, reduces the force required to move the lens, prevents damage to the lens, extends the device's lifespan, and facilitates cleaning. When the tool reaches the lesion, medication is placed into the drug delivery chamber, which is then discharged through a drug delivery port, thus treating the patient's intestines and further enhancing the device's practicality.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0037] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0038] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 A deformable intestinal examination and treatment tool includes an inner tube 1 and an outer tube 2, as well as a convex membrane 3, a suction port 4, a drug delivery port 5, a drug delivery tube 6, a balloon tube 7, a fiberscope 8, and a balloon 9. The inner tube 1 is fitted inside the outer tube 2, and there is a gap between the inner tube 1 and the outer tube 2. The right ends of both the inner tube 1 and the outer tube 2 are closed. The convex membrane 3 is fixedly installed at the right end of the inner tube 1. The fiberscope 8 is inserted inside the inner tube 1, and the lens of the fiberscope 8 is located inside the convex membrane 3.

[0039] The inner region of the inner tube 1 forms the core cavity for inserting the fiberscope 8; the region between the inner tube 1 and the outer tube 2 forms the suction cavity for aspirating liquids and obstructions in the intestine, and the right end of the suction cavity is a closed end; the inner regions of multiple drug delivery tubes 6 form the drug delivery cavity for delivering drugs into the intestine; multiple balloon tubes 7 together form a deformable layer to assist the right end of the tool during its movement.

[0040] Preferably, the right end of the suction cavity is provided with multiple suction holes 4, which are evenly distributed in a circular array on the right end face of the suction cavity. The left end of the suction cavity is used to connect a negative pressure pump to provide suction force. Fluid and obstructions in the intestine are drawn into the suction cavity through the suction holes 4 and finally discharged to the outside. Additionally, one of the multiple suction cavities can be connected to an external liquid delivery pump, which delivers cleaning fluid into this suction cavity, allowing the cleaning fluid to rinse the convex membrane 3. The remaining suction cavities are used to aspirate liquid.

[0041] Preferably, multiple drug delivery tubes 6 are fixedly installed on the outer wall of the outer tube 2. These tubes are arranged in a circumferential array with equal spacing on the outer wall of the outer tube 2. Furthermore, multiple drug delivery holes 5 are provided on the right end of the outer wall of each tube 6, arranged in a linear array with equal spacing. The left end of each tube 6 is used to connect to an external drug delivery pump or syringe, allowing the drug to flow out through the drug delivery holes 5, thereby treating the lesion in the intestine. Additionally, the length of the drug delivery tube 6 can extend to the right end face of the outer tube 2, making it more convenient to administer medication to the lesion.

[0042] Preferably, multiple airbag tubes 7 are fixedly installed on the outer wall of the right end of the outer tube 2, and the multiple airbag tubes 7 are distributed in a circumferential array at equal intervals on the outer wall of the outer tube 2. Each airbag tube 7 is composed of multiple airbags 9, which are connected sequentially along the length of the outer tube 2, and the multiple airbags 9 in each airbag tube 7 are interconnected; the leftmost airbag 9 is connected to an external inflation pump. By inflating and deflating the airbag tubes 7 at different positions using the inflation pump, the expansion degree and stiffness of the corresponding airbag tubes 7 are changed, thereby causing the right end of the outer tube 2 to bend.

[0043] Preferably, the outer end of the outer tube 2 is also provided with a lubricating layer to reduce the friction between the outer tube 2 and the intestine, thereby reducing the patient's discomfort during the treatment process.

[0044] Preferably, the drug delivery tube 6 and the airbag tube 7 are arranged at intervals between each other in the outer tube 2.

[0045] In this invention, the deformable layers are initially inflated, keeping the inner tube 1 and outer tube 2 vertical. This facilitates the insertion of the tool into the patient's intestine by medical personnel. Simultaneously, the fiberscope 8 is inserted inside the inner tube 1, with its lens located inside the convex membrane 3. The fiberscope 8 provides power to propel the tool through the intestine, allowing observation of the intestinal environment. When the tool encounters an obstruction, the suction hole 4 within the suction chamber removes the obstruction and also suctions intestinal fluid. When a bend is needed, the corresponding balloon tube 7 is deflated, altering its expansion and rigidity, causing the right end of the outer tube 2 to bend. This, combined with the force exerted by the lens of the fiberscope 8, makes the tool easier to bend and reduces the force required to drive the lens, preventing damage and extending the device's lifespan. It also facilitates cleaning. When the tool reaches the lesion, medication is placed into the drug delivery chamber, which is then discharged through the drug delivery hole 5. This allows for treatment of the patient's intestinal tract, further enhancing the device's practicality.

[0046] Example 2: In some embodiments, such as Figure 5As shown, in a preferred embodiment of this utility model, the convex membrane 3 is made of transparent soft rubber and is tightly connected to the right end of the inner tube 1 through a sealing ring, so that the lens part of the fiber scope 8 can be inserted to observe the inside of the patient's intestine.

[0047] Example 3: In some embodiments, such as Figure 6 As shown, in a preferred embodiment of this utility model, the left ends of the inner tube 1 and the outer tube 2 are provided with a multi-stage telescopic structure. The multi-stage telescopic structure can be a corrugated tube structure, which is used to expand the range of motion of the treatment tool and further improve the practicality of the device. At the same time, the drug delivery tube 6 will also be extended accordingly.

[0048] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
