Endoscope with disposable sheath

Abstract

This utility model discloses an endoscope with a disposable sleeve, relating to the technical field of endoscope protection devices. It includes an endoscope inlet tube, with a flexible protective sleeve fixedly connected to the bottom of the inlet tube for protecting the endoscope. A lens is fixedly connected to the end of the flexible protective sleeve away from the inlet tube. The flexible protective sleeve has eight drainage holes for guiding secretions. During surgery, if secretions obstruct the endoscope's view, a drainage pump can be activated to create negative pressure in the connecting tube via a one-way valve. The connecting tube, through its various connecting branches, creates negative pressure in the drainage holes to draw in the secretions. Finally, the secretions are discharged through the drainage holes, connecting branches, connecting tube, one-way valve, and connector, ultimately through the drainage pump. After the secretions are cleared, the endoscope image becomes clearer, solving the technical problems of existing endoscope protective sleeves having limited effectiveness and the endoscope lens being easily obscured by mucus or blood, affecting light transmission.

Description

Technical Field

[0001] This utility model relates to the technical field of endoscope protection devices, and in particular to an endoscope with a disposable sleeve. Background Technology

[0002] An endoscope is a medical instrument used to examine internal organs for lesions. It is widely used in clinical practice for examining various organs, such as intestinal endoscopes, gastrointestinal endoscopes, hysteroscopes, and otolaryngoscopes. During an examination, the endoscope needs to be inserted into the human organ. After the endoscope enters the body, it becomes contaminated. Therefore, it must be disinfected after each use before reuse. Currently, the disinfection method usually involves soaking the endoscope in disinfectant for more than 15 minutes. However, in reality, due to the large number of patients requiring endoscopy, the endoscope may be removed and reused before being soaked for more than 15 minutes after one patient's use. This leads to some unreliability in the disinfection method and the risk of cross-infection. Therefore, an endoscope sheath (also called an endoscope protective sleeve) that can be attached to the surface of the endoscope has been developed to protect it.

[0003] Currently, most protective sleeves for existing endoscopes achieve their effect using the following technologies; Materials selection techniques include biocompatible materials, flexible materials, chemically resistant materials, and transparent materials; Structural design technology, including lens protection structure, sealing structure, adapter structure and protective structure; Manufacturing process technologies, including high-precision coating processes, integral molding processes, and surface treatment processes.

[0004] Currently, the protective sleeves for existing endoscopes have been found to have at least the following technical problems in actual use; Existing endoscope protective sleeves are mostly single-tube structures. Although they can protect the endoscope body from contaminants such as sewage, body fluids, and blood, they lack suction devices. Mucus and blood secreted by the patient's organs can easily cover the endoscope lens, affecting light transmission and the accuracy of the examination. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an endoscope with a disposable sleeve, which solves the problems of limited protective sleeves and endoscope lenses being easily covered by mucus or blood, thus affecting light transmission.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An endoscope with a disposable cannula includes an endoscope inlet tube, a flexible protective sleeve for protecting the endoscope fixedly connected to the bottom of the endoscope inlet tube, an endoscope being fitted together inside the endoscope inlet tube and the flexible protective sleeve, a lens being fixedly connected to the end of the flexible protective sleeve away from the endoscope inlet tube, eight drainage holes for guiding secretions being provided on the flexible protective sleeve, and an aspiration mechanism for aspirating secretions being fixedly connected to the surface of the endoscope inlet tube, the aspiration mechanism including a one-way valve, a connector, a connecting tube and a connecting branch tube.

[0007] Preferably, the connecting tube is fixedly connected to the surface of the endoscope inlet tube, and the connecting tube is fixedly connected to the one-way valve.

[0008] Preferably, the number of connecting branches is eight, and all eight connecting branches are fixedly connected to the connecting pipe.

[0009] Preferably, all eight connecting tubes pass through the endoscope inlet tube and are interconnected with the eight drainage holes respectively.

[0010] Preferably, the end of the check valve furthest from the connecting pipe is fixedly connected to the connector, and the check valve is connected to an external drainage pump through the connector.

[0011] Preferably, the inner walls of the eight drainage holes are all fixedly connected with several steel wire support rings, which are embedded into the inner side of the drainage holes during the production of the flexible protective sleeve using embedded technology.

[0012] Compared with the prior art, the present invention has the following beneficial effects: I. In this application, an endoscope is inserted into a flexible protective sleeve through an endoscope insertion tube. Internal organs are observed through a lens. Before surgery, it is connected to an external drainage pump via a connector. During surgery, if secretions obstruct the endoscope's view, the drainage pump is activated, creating negative pressure in the connecting tube via a one-way valve. This negative pressure, generated through various connecting branches, draws in the secretions through the drainage holes. The secretions are then discharged through the drainage holes, connecting branches, connecting tube, one-way valve, and connector via the drainage pump. Clearing the secretions makes the endoscope image clearer, solving the technical problems of existing endoscope protective sleeves having limited effectiveness and the endoscope lens being easily obscured by mucus or blood, affecting light transmission.

[0013] Second, this application has a simple structure. During production, molding and embedding technology can be used to embed the connecting tube, connecting branch tube and steel wire support ring into the endoscope entry tube and flexible protective sleeve together. The one-way valve and connecting tube can be produced separately before final assembly. The above production technologies are all existing mature technologies. The production material cost of this application is also not high, which makes this application easy to produce and has low production cost. The cost of direct disposal after single use is also low.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problems of existing endoscope protective sleeves having limited effectiveness and endoscope lenses being easily covered by mucus or blood, thus affecting light transmission. The overall concept is as follows: To address the problems existing in the prior art, this utility model provides an endoscope with a disposable sleeve, including an endoscope inlet tube 1, a flexible protective sleeve 2 for protecting the endoscope fixedly connected to the bottom of the endoscope inlet tube 1, an endoscope being sleeved together inside the endoscope inlet tube 1 and the flexible protective sleeve 2, a lens 3 fixedly connected to the end of the flexible protective sleeve 2 away from the endoscope inlet tube 1, eight drainage holes 201 for guiding secretions being opened on the flexible protective sleeve 2, and an aspiration mechanism for aspirating secretions being fixedly connected to the surface of the endoscope inlet tube 1, the aspiration mechanism including a one-way valve 4, a connector 401, a connecting tube 5 and a connecting branch tube 501.

[0022] The connecting tube 5 is fixedly connected to the surface of the endoscope inlet tube 1, and the connecting tube 5 is fixedly connected to the one-way valve 4.

[0023] There are eight connecting pipes 501, and all eight connecting pipes 501 are fixedly connected to the connecting pipe 5.

[0024] All eight connecting tubes 501 pass through the endoscope inlet tube 1 and are interconnected with the eight drainage holes 201 respectively.

[0025] The end of the one-way valve 4 away from the connecting pipe 5 is fixedly connected to the connector 401, and the one-way valve 4 is connected to the external drainage pump through the connector 401.

[0026] The inner walls of the eight drainage holes 201 are all fixedly connected with several steel wire support rings 6. The steel wire support rings 6 are embedded into the inner side of the drainage holes 201 using embedded technology during the production of the flexible protective sleeve 2.

[0027] Endoscope entry tube 1: used to insert into the flexible protective sleeve 2, providing an insertion channel for the endoscope, and also serving as a carrier for connecting components such as the suction mechanism.

[0028] Flexible protective sleeve 2: Used to protect the endoscope, it is fixedly connected to the bottom of the endoscope inlet tube 1. The endoscope can be fitted inside it, and a drainage hole 201 is provided to provide a channel for suctioning secretions.

[0029] Lens 3: Fixedly connected to the end of the flexible protective sleeve 2 away from the endoscope inlet tube 1, used to observe internal organs of the human body, enabling doctors to see the internal condition.

[0030] One-way valve 4: It is fixedly connected to the connecting pipe 5 and the connector 401. When aspirating secretions, it ensures that the liquid can only flow from the connecting pipe 5 to the connector 401 to prevent backflow. It works with the drainage pump to aspirate and discharge secretions.

[0031] Connecting tube 5: It is fixedly connected to the surface of the endoscope inlet tube 1 and connected to the one-way valve 4. It is the channel connecting each connecting branch tube 501 and the one-way valve 4. It generates negative pressure under the action of the drainage pump to absorb secretions.

[0032] Steel wire support ring 6: It is fixedly connected to the inner wall of the eight drainage holes 201. It is embedded in the inner side of the drainage holes 201 during the production of the flexible protective sleeve 2 using embedded technology. It plays a role in supporting the drainage holes 201, preventing the drainage holes 201 from deforming during the process of absorbing secretions, and ensuring the smooth flow of the absorption channel.

[0033] Drainage holes 201: Eight holes are formed on the flexible protective sleeve 2 to guide secretions. They are connected to the connecting tube 501 and the secretions are absorbed under negative pressure.

[0034] Connector 401: It is fixedly connected to the end of the one-way valve 4 away from the connecting pipe 5, and is used to connect to an external drainage pump to realize the docking of the drainage pump with the entire suction mechanism so as to suction secretions.

[0035] Connecting tubes 501: There are eight of them, all of which are fixedly connected to the connecting tube 5. They penetrate the endoscope into the tube 1 and are connected to the eight drainage holes 201 respectively. They are channels that connect the drainage holes 201 to the connecting tube 5, and transfer secretions from the drainage holes 201 to the connecting tube 5.

[0036] Working principle: In this application, an endoscope is inserted into the flexible protective sleeve 2 through the endoscope entry tube 1 and observed through the lens 3. Before the operation, it is connected to an external drainage pump through the connector 401. During the operation, if secretions obstruct the endoscope's view, the drainage pump can be activated to create negative pressure in the connecting tube 5 through the one-way valve 4. The connecting tube 5 creates negative pressure in the drainage hole 201 through each connecting branch tube 501 to draw out the secretions. Finally, the secretions are discharged from the body through the drainage hole 201, connecting branch tube 501, connecting tube 5, one-way valve 4, and connector 401 via the drainage pump. After the secretions are cleared, the image of the endoscope becomes clearer.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
