Description

Technical Field

[0001] The invention relates to the field of minimally invasive surgical instruments, and in particular to an endoscope lens cleaning device used in narrow spaces. Background Art

[0002] As an indispensable tool in ENT surgery and examination, ENT endoscope has the advantages of minimal trauma, high resolution, and high success rate. Otoscope is used for examination or surgical evaluation of the external ear, middle ear and other parts. It usually adopts a natural approach through the ear canal, without the need for external incision or with a small incision. The structures of the upper, middle and lower tympanic cavity that are difficult to observe under a microscope can be clearly seen at close range. The nasal endoscope has good lighting and a clear field of view. With the matching surgical instruments, the surgery can be made more delicate and can reach areas that traditional surgery cannot reach. The laryngeal endoscope uses a high-brightness LED light source and optical fiber lighting. It has strong brightness and no focal length limit. Both near and far scenes can be clearly observed, and it can provide high-resolution images. The use of these endoscopes can improve the accuracy and safety of surgery.

[0003] During the use of ENT endoscopes, the problem of lens cleaning is often faced. Due to the narrow space in the ENT, nose and throat, the diameter of the ENT endoscope lens is smaller, the surgical cavity is more limited, and the lens fogging and contamination with patient body fluids will occur more frequently. This not only affects the clarity of the surgical field of view, but may also increase surgical risks and the possibility of postoperative infection. At present, the cleaning of the ENT endoscope lens mainly relies on manual wiping. When the lens field of view is affected by body fluids or fog, the lens needs to be pulled out and manually wiped, and then inserted into the patient's body to continue the operation. It cannot be cleaned immediately, which is inefficient and affects the safety of the operation.

[0004] In view of the above problems, there is an urgent need for an endoscopic lens cleaning device for narrow spaces that can improve cleaning efficiency and simplify the cleaning process, so as to improve the efficiency and safety of ENT endoscopic surgery. Summary of the invention

[0005] The purpose of the present invention is to provide an endoscope lens cleaning device for narrow spaces. The cleaning device is put on the endoscope and placed into the narrow space in the ear, nose and throat of the patient. The endoscope lens can be cleaned in the body, improving the cleaning efficiency and preventing the lens from fogging, thereby ensuring the efficiency and safety of the operation.

[0006] In order to achieve the above-mentioned object, the present invention provides an endoscope lens cleaning device for use in a narrow space, comprising a bushing, a cleaning body, and a liquid inlet pipe;

[0007] The cleaning body is at least arranged at the distal end of the bushing, and the cleaning body is formed with a channel for the endoscope lens to pass through;

[0008] The liquid inlet pipe is connected to the bushing, and the liquid inlet pipe is used to inject liquid of a set temperature into the inner space of the bushing;

[0009] The distal end refers to the side away from the operator.

[0010] Optionally, the cleaning body is any one of medical sponge, rubber, gel or similar functional materials.

[0011] Optionally, the cleaning body is disposed inside the sleeve, and the cleaning body extends from a proximal end of the sleeve to a distal end of the sleeve, wherein the proximal end refers to a side close to an operator.

[0012] Optionally, the cleaning body comprises a plurality of symmetrical or asymmetrical sub-cleaning members, and the inner diameter of the channel formed by the sub-cleaning members for the endoscope lens to pass through is less than or equal to the diameter of the endoscope lens.

[0013] Optionally, the cleaning body is provided with a plurality of liquid outlet holes, and liquid flows through the liquid outlet holes to clean the cleaning body.

[0014] Optionally, the liquid forms a liquid layer surrounding the endoscope lens in the inner space of the sleeve.

[0015] Optionally, the number of the liquid inlet pipes is greater than or equal to 1, and the set temperature is controlled by an external device, generally 35°C-40°C.

[0016] Optionally, the bushing is made of any one of aluminum alloy, copper alloy and stainless steel.

[0017] Optionally, the endoscope is used for observation in a narrow space, and the diameter of the narrow space is 1mm-20mm.

[0018] Optionally, when the cleaning body is in a closed state, deep cleaning of the lens can be achieved; when the cleaning body is in an open state, self-cleaning of the cleaning body can be achieved.

[0019] Compared with the prior art, the technical solution of the present invention has at least the following beneficial effects:

[0020] 1) During the operation, the cleaning device is put on the endoscope and placed in a narrow space. When the lens is contaminated with the patient's body fluids or fogged during use, the lens can be retracted into the cleaning body, the cleaning body is closed, and the lens is brought into contact with the cleaning body by pushing, pulling, and rotating to achieve cleaning; if the stain is serious, the corresponding liquid can be injected into the cleaning body to assist cleaning and improve cleaning efficiency.

[0021] 2) Furthermore, the cleaning body is provided with a plurality of liquid outlet holes. When the lens is pushed out and the cleaning body is opened, the liquid in the liquid layer can flow through the liquid outlet holes to clean the cleaning body, thereby extending the service life of the cleaning body.

[0022] 3) Furthermore, when the endoscope is used for observation in a narrow space (such as 1mm-20mm), the cleaning device can clean the lens inside the patient's body without removing the lens from the body, thereby improving the efficiency and safety of the operation.

[0034] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0035] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] The term "distal" refers to the side away from the operator, and "proximal" refers to the side close to the operator.

[0038] As described in the background technology, due to the narrow space in the ENT, the diameter of the ENT endoscope lens is smaller, the surgical cavity is more limited, and the lens fogging and contamination with patient body fluids are more frequent, thereby affecting the clarity of the surgical field of view, increasing surgical risks and the possibility of postoperative infection. When the lens field of view is affected by body fluids or fog, the lens needs to be pulled out for manual wiping or automatic cleaning, which cannot be cleaned immediately, is inefficient and affects the safety of the operation.

[0039] Therefore, in order to improve the cleaning efficiency of the lens and prevent the lens from fogging, the present invention designs a cleaning device. When the cleaning device is put on the endoscope and placed in the narrow space in the ear, nose and throat of the patient, the cleaning device can clean the lens inside the body without pulling the lens out of the body, thereby improving the efficiency and safety of the operation. Specifically, the present invention provides an endoscope lens cleaning device for narrow spaces, comprising a sleeve, a cleaning body, and a liquid inlet pipe, which are described in detail below.

[0040] like Figure 2 and Figure 3 As shown, the cleaning body 2 is at least arranged at the distal end of the bushing 1 , and the cleaning body is formed with a channel 5 for the endoscope lens 4 to pass through.

[0041] The cleaning body 2 can be arranged at the distal end of the liner 1 or inside the liner 1; when the cleaning body 2 is arranged inside the liner 1, the cleaning body 2 extends from the proximal end of the liner 1 to the distal end of the liner 1 (see Figure 1 ), all-round cleaning of the endoscope lens 4 can be achieved. The cleaning body 2 is formed with a channel 5 for the endoscope lens 4 to pass through, and the endoscope lens 4 can be extended and retracted in the channel 5 by the push-pull device of the endoscope.

[0042] In some embodiments, the bushing 1 is made of metal, and can be any one of aluminum alloy, copper alloy, and stainless steel. During surgery, the metal bushing can be sterilized by appropriate means such as low-temperature plasma to prevent intraoperative contamination.

[0043] In some embodiments, the cleaning body 2 is made of a flexible elastic material, which can be deformed under the action of a force and restore its shape when the force disappears. For example, the cleaning body 2 can be any one of medical sponge, rubber, gel or similar functional materials.

[0044] The cleaning body 2 comprises a plurality of sub-cleaning members distributed circumferentially on the inner wall of the liner 1, and these sub-cleaning members may be arranged symmetrically (see Figure 2 a), can also be arranged asymmetrically (see Figure 2 b). The outer sides of the plurality of sub-cleaning members are connected to the inner wall of the bushing 1, and the inner side forms a channel 5 for the endoscope lens 4 to pass through. The inner diameter of the channel 5 is less than or equal to the diameter of the endoscope lens 4, and the sub-cleaning members can be contacted to a large extent to achieve rapid cleaning of the lens. In some embodiments, when the sub-cleaning members are arranged asymmetrically, the center of the channel 5 deviates from the center of the endoscope lens 4 (see Figure 2 b) in the figure, and the sub-cleaning member has an uneven wiping surface, the contact area between the lens and the sub-cleaning member is larger when the lens is in a rotating state, which is more conducive to deep cleaning of the lens.

[0045] It can be understood that when the inner diameter of the channel 5 formed by each sub-cleaning member is 0, each sub-cleaning member is in close contact but not connected, and the contact area between the sub-cleaning member and the endoscope lens 4 is the largest, and the cleaning effect is better. Figure 2 In the closed state, the inner diameter of the channel 5 formed by the sub-cleaning member is relatively small.

[0046] Also, see Figure 3 When in use, the thrust generated when the endoscope lens 4 is extended causes the sub-cleaning member to deform, the inner diameter of the channel 5 formed by the sub-cleaning member becomes larger, the contact area between the endoscope lens 4 and the sub-cleaning member is reduced, and the friction force is increased, thereby producing a stronger cleaning effect on the endoscope lens 4.

[0047] The liquid inlet pipe 3 is connected to the bushing 1 and is used to inject liquid of a set temperature into the inner space of the bushing 1. The liquid inlet pipe 3 in this example is connected to the proximal end of the bushing 1.

[0048] The injected liquid can form a liquid layer 6 around the endoscope lens 4 in the internal space of the sleeve 1, thereby achieving uniform heating of the lens, preventing the lens from fogging and affecting the surgical field of view, and also assisting in cleaning and improving cleaning efficiency.

[0049] The number of the liquid inlet tubes 3 is greater than or equal to 1. When the number of the liquid inlet tubes 3 is large, the liquid can be injected faster and distributed more evenly in the internal space of the bushing 1, thereby heating the endoscope lens 4 more evenly.

[0050] In addition, the set temperature of the liquid is controlled by an external device, which is generally 35°C-40°C, so as to keep the endoscope lens 4 roughly consistent with the patient's body temperature, and better prevent the lens from fogging due to temperature difference.

[0051] In some embodiments, the cleaning body 2 is provided with a plurality of liquid outlet holes 21, and the liquid in the liquid layer 6 can flow through the liquid outlet holes 21 to clean the cleaning body 2, thereby extending the service life of the cleaning body 2 and achieving a better cleaning effect on the lens. When the cleaning body 2 reaches the maximum number of cleaning times, the old cleaning body 2 can be removed and replaced, or the cleaning body 2 can be dissolved with a specific organic solvent and then refilled. After the liquid flows out of the liquid outlet holes 21, it is discharged through the suction tube of the surgical area.

[0052] Therefore, the liquid in the liquid layer 6 has the dual functions of heating the endoscope lens 4 and washing the cleaning body 2 .

[0053] In some embodiments, the cleaning body 2 is an integral body, the outer side of which is connected to the inner wall of the bushing 1, and the inner side forms a channel 5 for the endoscopic lens 4 to pass through, and the inner diameter of the channel 5 is less than or equal to the diameter of the endoscopic lens 4; when the endoscopic lens 4 passes through the channel 5, the cleaning body 2 is squeezed to deform it, so that the inner diameter of the channel 5 increases, and at the same time, the inner side of the cleaning body 2 will closely contact the endoscopic lens 4 to clean it.

[0054] In the embodiment where the cleaning body 2 extends from the proximal end to the distal end in the sleeve 1, after the liquid of set temperature is injected into the internal space of the sleeve 1, it can be absorbed by the cleaning body 2 to achieve cleaning of the cleaning body 2. At the same time, the endoscope lens 4 can be heated by heat conduction of the cleaning body 2.

[0055] In this embodiment, when the cleaning body 2 is in a closed state, the lens can be cleaned; when the cleaning body 2 is in an open state, the wiping surface of the cleaning body 2 can be self-cleaned.

[0056] The cleaning device is put on the endoscope and placed in a narrow space to clean the endoscope. The diameter of the narrow space is 1mm-20mm. As an example, the endoscope used in the narrow space may be an ENT endoscope.

[0057] The following describes in detail the method for using the endoscope lens cleaning device for narrow spaces provided by the present invention in conjunction with the embodiments.

[0058] Example

[0059] Put the cleaning device on the endoscope and place it into a narrow space with a diameter of 5 mm in the ear, nose and throat. First, use the push-pull device of the endoscope to rotate and extend the endoscope lens into the cleaning device. The lens rotates along the channel formed by the medical sponge to squeeze the uneven cleaning body. The contact area between the lens and the cleaning body is large, which can achieve deep cleaning of the lens. When the lens is contaminated with patient fluids or fogged during use, the lens is retracted into the medical sponge. The lens is rotated while squeezing the cleaning body to achieve deep cleaning again. At the same time, the liquid inlet pipe connected to the sleeve injects 37°C liquid into the sleeve to form a liquid layer around the lens to heat the lens or assist in cleaning. After cleaning, the lens can continue to be used through the medical sponge, and the liquid in the liquid layer can flow through the liquid outlet hole of the medical sponge to achieve self-cleaning of the medical sponge. After the liquid flows out of the liquid outlet hole, it is discharged through the suction tube in the surgical area.
