Description

Technical Field

[0001] The utility model relates to the technical field of endoscope glue injection, in particular to a glue syringe with an endoscope protection function. Background Art

[0002] In the treatment of bronchial leakage, one method is to inject bioglue into the leakage point through the injection hole of the endoscope through an injection needle to seal the leakage point. The injected bioglue will solidify when it comes into contact with water, thus sealing the leakage point. However, after the injection of the glue seal is completed, bioglue will inevitably remain on the end of the injection needle and it is difficult to completely remove it. Therefore, after the injection needle is retracted to the injection hole of the endoscope, the bioglue on the end of the injection needle tends to adhere to the injection hole mouth. After solidifying in contact with water, it is difficult to clean. Furthermore, it will cause contamination of the endoscope lens. Endoscope lenses are expensive and non-disposable products, so contamination of the endoscope will result in significant economic losses.

[0003] For example, the Chinese invention patent with publication number CN118142054A discloses a visual nasal and throat topical anesthesia spray tube, which belongs to the technical field of topical anesthesia spray tubes. In response to the current problem of being unable to visually spray anesthetic liquid and the limited spraying range, the present invention provides a visual spray head that integrates lighting, imaging and spraying functions, connects the visual spray head to one end of a catheter, and connects an injector to the other end of the catheter. The injector adjusts the injection pressure of the liquid so that the visual spray head and one end of the catheter enter the throat through the patient's nasal cavity. The gathered protective cover prevents the secretions from the oral and nasal cavity from adhering to the visual spray head. After reaching the area to be anesthetized, the anesthetic liquid is used to generate pressure on the spray assembly, so that the nozzle drives the push disk to open the protective cover, fully exposing the field of view of the spraying range, making it easier for the doctor to observe the position of the nozzle during spraying, thereby performing spray anesthesia in a visual environment.

[0004] In this solution, a protective cover can be provided to protect the imaging lens to prevent secretions from adhering. However, in this invention, the protective cover covers the nozzle and the lens together. In the glue injection scenario, the biological glue remaining at the nozzle lacks protection when the glue is withdrawn after the injection is completed, and there is still the problem of contaminating the lens.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1 、 2 As shown in Example 1, a glue syringe with an endoscope protection function includes an outer glue injection tube 2 for slidingly passing through the injection hole 1 of an endoscope, and an inner glue injection tube 3 is slidingly provided in the outer glue injection tube 2. The outer glue injection tube 2 can provide a channel and protection for the passage of the inner glue injection tube 3. The tail ends of the outer glue injection tube 2 and the inner glue injection tube 3 are both connected to a pushing handle 4, and the pushing handle facilitates the pushing and pulling of the outer glue injection tube and the inner glue injection tube before and after glue injection. A connecting ring 5 is provided at the front end of the outer glue injection tube 2, and the setting of the connecting ring 5 provides a support base for the installation of the spring wire skeleton. The connecting ring 5 is connected to the spring wire skeleton 6 on the circumferential outside, and the spring wire skeleton 6 is provided with a soft skin 7, so that the front end of the inner glue injection tube can be accommodated and protected after the glue is injected into the inner glue tube, so as to prevent the biological glue adhering to the front end of the inner glue injection tube from contaminating the injection hole or the endoscope lens.

[0030] In this embodiment, Figure 4 、 6 As shown, the spring wire skeleton 6 includes a number of spring wires 8 arranged at equal intervals along the outside of the connecting ring 5, and the soft skin 7 is fixedly connected to the number of spring wires 8. The spring wires provide an elastic support basis for the soft skin, and the soft skin is used to play a shielding effect to prevent the residual biological glue from contacting the endoscope. The soft skin can be fixed on the inner side of the spring wire in a ring form, or it can be arranged between adjacent spring wires. The soft skin is made of conventional rubber material and has a certain elasticity and tension. It can be stretched to a certain range with the spring wire and play a certain blocking role. In this embodiment, the soft skin 7 is a rubber film, and the soft skin 7 is arranged between adjacent spring wires 8. When the outer tube for injection moves, the spring wire directly contacts the injection hole of the endoscope to achieve sliding guidance.

[0031] When this embodiment is used, Figure 3 、 5 As shown, first use the pushing handle to pass the outer injection tube into the injection hole of the endoscope. Then, after the endoscope moves to the injection position, continue to push the handle to pass the spring wire part connected to the outer injection tube through the injection hole of the endoscope. At the same time, operate the pushing handle to transport the inner injection tube inward, so that the front end of the inner injection tube passes through the range of the spring wire and the soft skin, and perform the injection operation. After completion, the front end of the inner injection tube is retracted into the inner side of the soft skin, and the outer injection tube and the inner injection tube are simultaneously pulled out from the injection hole of the endoscope using the blocking of the soft skin.

[0032] Example 2, based on Example 1, the middle part of the spring wire 8 is hingedly connected to the connecting ring 5. When it has not penetrated into the endoscope injection hole 1, the distance between the tail end of the spring wire 8 and the axis of the connecting ring 5 is greater than the radius of the endoscope injection hole 1. Therefore, when the front end of the spring wire moves out of the endoscope injection hole, the tail end can be squeezed inwardly under the action of the endoscope injection hole wall, prompting the spring wire to rotate along the hinged part.

[0033] In this embodiment, Figure 7 As shown, the spring wire 8 includes a concave section 9, which is hinged to the connecting ring 5. One end of the concave section 9 is connected to the arc section 10 and the other end is connected to the arch section 11. The bending direction of the arc section 10 is similar to the bending direction of the arch section 26, thereby forming an approximately M-shaped elastic body.

[0034] When the spring wire skeleton 6 is in use, it is completely within the endoscope injection port 1. Both the arcuate segment 10 and the arched segment 11 of the spring wire skeleton 6 are squeezed by the endoscope injection port 1 and elastically deformed. When the front end of the arched segment is squeezed, the soft cover 7 on the arched segment partially or completely closes the front end of the injection inner tube 3. When the injection outer tube is pushed so that the arched segment 11 at the front end of the spring wire skeleton 6 is outside the injection outer tube 2 and the arcuate segment 10 is inside the injection port of the endoscope, the arcuate segment at the rear end of the spring wire skeleton 6 relaxes under its own elastic action, releasing the outward restraint of the injection port on the arched segment, allowing the spring wire skeleton to rotate along the hinged portion of the concave segment and the connecting ring, thereby expanding the arched segment outward, thereby driving the front end of the soft cover 7 to expand, and opening the forward passage of the injection inner tube. At this time, the injection inner tube can be pushed forward to pass through for injection. After the glue injection is completed, the glue injection inner tube is retracted into the glue injection outer tube. At this time, the biological glue adhered to the tube mouth of the front end of the glue injection inner tube is located on the inner side of the soft skin. Then, after the glue injection outer tube is retracted into the endoscope injection hole, the endoscope injection hole simultaneously resumes the extrusion of the arc segment and the arch segment, thereby retracting the front end of the arch segment and closing the front end of the soft skin to avoid contamination caused by leakage of biological glue at the tube mouth of the inner glue injection inner tube.

[0035] Example 3, as an optional solution, is based on Example 1 and is different from Example 2 in that the spring wire 8 is fixedly arranged on the outside of the connecting ring 5. The spring wire is a straight elastic wire. The spring wire and the soft skin are relatively thin. They are arranged on the outside of the connecting ring and can form a certain gap between the tube mouth of the inner injection tube. Before injection, the outer injection tube is inserted into the injection hole of the endoscope under the sliding guidance of the spring wire. During injection, the inner injection tube can easily pass through the soft skin. After the injection is completed and the inner injection tube is retracted into the inner injection tube, the biological glue at the tube mouth of the inner injection tube is retracted into the inner side of the soft skin along with the tube mouth to avoid leakage and contamination.

[0036] Example 4, based on Example 2 or 3, Figure 8 As shown, the push handle 4 includes a handle shell 12 connected to the glue injection outer tube 2, a handle inner shell 13 is slidably provided in the handle shell 12, the front end of the handle inner shell 13 is connected to the glue injection inner tube 3, and the handle inner shell 13 is provided with a glue injection channel 14 connected to the glue injection inner tube 3. The tail of the handle inner shell 13 passes through the handle shell 12 and is provided with a connecting joint 15 connected to the glue injection channel 14. Before glue injection, it can be connected to the glue injection syringe through the connecting joint, and then glue is injected through the glue injection channel and the glue injection inner tube. As an option, a needle is provided at the front end of the glue injection inner tube, and glue injection is achieved by using the needle. When a needle is provided, the glue injection inner tube is pre-installed in the glue injection outer tube. Before and after glue injection, it is only necessary to push the needle out and put it into the glue injection outer tube. In addition, a limiting mechanism 16 is provided on the handle shell 12, and an adjustment mechanism 17 is provided between the handle shell 12 and the handle inner shell 13.

[0037] In this embodiment, a handle shell is provided for easy holding during glue injection. When in use, before inserting the glue injection outer tube into the injection hole of the endoscope, the position of the limiting mechanism is adjusted according to the actual length of the endoscope itself, so that when the handle shell is held to send the glue injection outer tube into the injection hole of the endoscope, the limiting mechanism can block the outer tube so that the front end of the spring wire leaks out of the injection hole of the endoscope, and the rear end of the spring wire is inside the injection hole of the endoscope.

[0038] Specifically, the limiting mechanism 16 includes an adjustment portion 18 provided at the front end of the handle housing 12. A limiting ring 19 is slidably provided on the adjustment portion 18. A plurality of slots 20 are formed at equal intervals on the adjustment portion 18. The limiting ring 19 is provided with a spring tongue 21 for engaging with the slots 20. Before the injection outer tube is inserted into the injection port of the endoscope, the spring tongue of the limiting ring is adjusted to engage with the slot at the corresponding insertion length according to the length of the injection port of the endoscope. When the tube is fully inserted, the limiting ring contacts the end of the injection port of the endoscope, thereby limiting further insertion and preventing the problem of the spring wire completely detaching from the injection port due to excessive insertion.

[0039] In addition, the adjustment mechanism 17 includes a knob 22 that is rotated on the handle outer shell 12. The handle inner shell 13 is provided with a rack portion 23. A gear 24 is coaxially fixed to the knob 22 and meshes with the rack portion 23 through the gear 24. During the glue injection and sealing process, the knob is rotated, which drives the gear to rotate. The meshing action of the gear and the rack portion synchronously drives the handle inner shell to move, thereby pushing the glue injection inner tube connected to the handle inner shell to move, thereby achieving glue injection or tube retraction.

[0040] As a further embodiment, Figure 9 As shown, a viewing window 25 is provided on the outer handle housing 12, and a graduated scale is provided on the inner handle housing 13 along the thrust direction. The scale reading matches the extension length of the front end of the injection inner tube relative to the connecting ring. Thus, when the knob is turned to move the inner handle housing for injection, the extension length can be determined based on the scale reading in the viewing window.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
