Description

Technical Field

[0001] This invention relates to the field of endoscopy, and more particularly to a medical endoscope with protective features. Background Technology

[0002] Medical endoscopes are indispensable minimally invasive diagnostic and treatment devices in modern clinical medicine. They are widely used in many medical fields such as gastroenterology, respiratory medicine, and urology. By inserting a scope with a camera and operating instruments into the human body, it is possible to directly observe the tissue condition inside the body cavity. At the same time, it is possible to insert operating instruments such as clamps through the instrument channel to complete diagnostic and treatment operations such as tissue extraction, biopsy, and hemostasis. This greatly reduces the trauma to patients caused by traditional open surgery and improves the efficiency and accuracy of diagnosis and treatment.

[0003] When using an endoscope to extract human tissue for testing, the operator needs to insert sampling instruments such as clamps into the human body through the instrument channel of the endoscope, grasp the target tissue, and then remove it through the instrument channel. During this process, the human tissue carried by the clamps comes into contact with the inner wall of the instrument channel, causing tissue debris, body fluids, and other contaminants to adhere to the inner wall of the instrument channel. Because the surgical or treatment process is continuous, it is not possible to directly clean and disinfect the inner wall of the instrument channel in real time. When multiple tissue samples are required, the clamps used for subsequent sampling will be contaminated with residual tissue contaminants from previous samplings as they move through the instrument channel. This can lead to cross-contamination of tissue samples from different sites, affecting the accuracy of test results and potentially misleading clinical diagnoses, posing a safety hazard to the patient's treatment. Summary of the Invention

[0004] In order to overcome the shortcomings of existing endoscopes, such as inconvenience in cleaning and disinfection and the inability to directly clean the instrument channel during surgery or treatment, this invention provides a medical endoscope with protective functions.

[0005] The technical solution is as follows: A medical endoscope with protective function includes an endoscope body; an insertion tube is installed on the endoscope body; a camera is installed at the end of the insertion tube; an instrument channel is opened inside the endoscope body; the instrument channel passes through the insertion tube, and the inner wall of the instrument channel is smooth; it also includes an outer sheath connected to the insertion tube; an inner sheath is fitted inside the instrument channel; a sheath head is fixedly connected to both the outer and inner sheaths, and both the outer and inner sheaths are made of medical silicone; the sheath head is fitted onto the tail end of the insertion tube, and the inner sheath passes through the sheath head; a cleaning component for cleaning the inner sheath is connected to the outer sheath.

[0006] As a further preferred embodiment, the cleaning assembly includes a clamping ring connected to the sheath head, the inner surface of which is an inverted conical surface; one end of the clamping ring is fixedly connected to the sheath head, and the other end is inserted into the inner sheath, with the inserted end being a rubber end; a sealing rod, made of nickel-titanium alloy, is detachably connected inside the inner sheath; a sealing head is fixedly connected to the tail end of the sealing rod; the sealing head is located inside the clamping ring; an inlet pipe is connected to the outer sheath; a connecting groove is provided inside the outer sheath; an outlet groove is provided inside the sheath head; the outlet groove leads to the connection end between the clamping ring and the inner sheath; the outlet groove is connected to the inlet pipe through the connecting groove.

[0007] As a further preferred embodiment, it also includes a detachable protective sleeve attached to the lens body; the protective sleeve has a through groove; a connector is fixedly attached to the inner sleeve; a mating head is detachably threaded onto the connector; the other end of the mating head is inserted into the through groove; the inner sleeve and the through groove are connected through the mating head; a connecting sleeve is fixedly attached to the end of the sealing rod; the connecting sleeve is inserted into the through groove and is connected to the mating head.

[0008] As a further preferred option, a locking ring is fitted to the end of the outer sheath away from the sheath head.

[0009] As a further preferred option, several miniature vibration motors are fixedly connected to the sealing rod; a connecting wire is installed on the connecting sleeve to supply power to the miniature vibration motors.

[0010] As a further preferred option, the connector is made of medical-grade stainless steel.

[0011] By adopting the above structure, the present invention can not only meet the hygiene requirements of medical equipment, but also use its own weight to achieve the natural falling and positioning of the connector in the instrument channel.

[0012] As a further preferred option, a wiping cotton is provided on the outside of the sealing head.

[0013] By adopting the above structure, the present invention can wipe and clean the inner ring surface of the clamping ring, solving the problem that the saline solution entering the inner sheath cannot clean the inner ring surface of the clamping ring.

[0014] As a further preferred option, it also includes a protective lens; the protective lens is fixed to the head of the protective cover; the protective lens fits snugly against the camera.

[0015] As a further preferred option, the protective lens is made of medical-grade high-transparency tempered glass.

[0016] As a further preferred option, it also includes limit rods; several limit rods are fixed to the entrance end of the instrument channel.

[0017] This invention has the following advantages: The outer sheath protects the insertion tube entering the body, while the inner sheath isolates the surgical instruments from the instrument channel, thus preventing contamination of the insertion tube and instrument channel with human tissue. After the surgery, medical staff only need to remove the outer sheath from the insertion tube and pull the inner sheath out of the instrument channel, followed by simple cleaning of the insertion tube and instrument channel. No complex cleaning and disinfection procedures for the endoscope are required. This solves the problems of frequent cleaning and disinfection operations in existing technologies, which can easily damage precision electronic components, cause equipment malfunctions, shorten service life, and consume significant manpower, time, and resources, increasing the operating costs of medical institutions.

[0018] The sealing head of the sealing rod seals the compression ring, and then an external water pump delivers saline solution to the inner sheath. The saline solution entering the inner sheath does not flow into the patient's body through the sealed compression ring, but instead flows outward through the inner sheath, thus cleaning the inner wall of the sheath. Simultaneously, a micro-vibration motor generates high-frequency disturbances in the saline solution within the inner sheath, creating a vibration cleaning effect that significantly improves the ability to remove contaminants from the inner wall. This method allows for direct cleaning of the inner sheath during surgery, solving the problem of existing technologies that cannot directly clean the instrument channel during surgery or treatment. When multiple tissue samples are required, the clamps used for subsequent sampling can become contaminated with residual tissue contaminants from previous sampling as they move through the instrument channel, leading to cross-contamination of tissue samples from different sites. This can affect the accuracy of test results and may even mislead clinical diagnosis, posing a safety hazard to the patient's treatment. Attached Figure Description

[0030] Example 1: A medical endoscope with protective functions, such as Figures 1-9 As shown, it includes a mirror body 1; an insertion tube 1001 is installed on the mirror body 1; a camera 1002 is installed at the end of the insertion tube 1001; an instrument channel 1003 is opened inside the mirror body 1; the instrument channel 1003 passes through the insertion tube 1001, and the inner wall of the instrument channel 1003 is a smooth surface.

[0032] The cleaning assembly includes a clamping ring 105, a sealing rod 106, and an inlet pipe 201; the clamping ring 105 is fixedly connected to the sheath head 102; the inner ring surface of the clamping ring 105 is an inverted conical surface; one end of the clamping ring 105 is fixedly connected to the sheath head 102, and the other end is inserted into the inner sheath 104, and the end inserted into the inner sheath 104 is a rubber end 10501; the sealing rod 106 is detachably connected inside the inner sheath 104, and the sealing rod 106 is made of nickel-titanium alloy; A sealing head 10602 is fixedly connected to the tail end of the sealing rod 106; the sealing head 10602 is located inside the compression ring 105; an inlet pipe 201 is connected to the outer sheath 101; a connecting groove 10101 is provided inside the outer sheath 101; an outlet groove 10201 is provided inside the sheath head 102; the outlet groove 10201 leads to the connection end between the compression ring 105 and the inner sheath 104; the outlet groove 10201 is connected to the inlet pipe 201 through the connecting groove 10101.

[0033] It also includes a protective sleeve 107 and a connector 108; the protective sleeve 107 is threaded onto the end of the endpiece 1, and the protective sleeve 107 covers the entrance end of the instrument channel 1003; a through groove 10701 is provided inside the protective sleeve 107; a connector 10401 is fixedly connected to the inner sheath 104; the connector 10401 is detachably threadedly connected to the connector 108; the other end of the connector 108 is inserted into the through groove 10701; the inner sheath 104 and the through groove 10701 are connected through the connector 108; a connecting sleeve 10601 is fixedly connected to the end of the sealing rod 106; the connecting sleeve 10601 is inserted into the through groove 10701 and is connected to the connector 108.

[0034] A locking ring 10102 is fitted on the outer side of the end of the outer sheath 101 away from the sheath head 102.

[0035] Several miniature vibration motors 202 are fixedly connected to the sealing rod 106, and a sealing film is fitted on the outside of each miniature vibration motor 202; a connecting wire is installed on the connecting sleeve 10601, and all the miniature vibration motors 202 are connected to an external power source through the connecting wire.

[0036] Working principle of Example 1: First, medical staff grasp the upper end of the outer sheath 101 and fold it outwards. Then, they pull it downwards, folding the outer sheath 101 outwards to the lower outer side of the sheath head 102. At this time, as... Figure 8As shown, the outer sheath 101 is located below the sheath head 102, and the inner sheath 104 is located above the sheath head 102, with the inner sheath 104 fully exposed to the outside. Then, the medical staff grasps the endoscope 1 and inverts it so that the lower end of the insertion tube 1001 faces upwards. Next, the medical staff inserts the connector 10401 into the instrument channel 1003. At this time, under the action of gravity, the medical-grade stainless steel connector 10401 will naturally slide downwards within the instrument channel 1003, then pass through the instrument channel 1003 and protrude from the other end of the instrument channel 1003. This solves the problem that the silicone inner sheath 104 is difficult to pass through the narrow instrument channel 1003, making it easier for the medical staff to fit the inner sheath 104 into the instrument channel 1003. After the connector 10401 protrudes from the opening of the instrument channel 1003, the medical staff screws the connector 10401 into the connector 108, and then inserts the connector 108 into the protective sleeve. The inner sheath 104 is then fixedly connected to the instrument channel 1003 by screwing the protective sleeve 107 onto the outside of the inlet end of the instrument channel 1003 within the through groove 10701 on the instrument channel 107. The protective sleeve 107 prevents medical personnel from bumping into the inner sheath 104 and causing it to fall off. After the inner sheath 104 is installed, the sheath head 102 is precisely aligned with the lower end of the insertion tube 1001. Then, the medical personnel invert the endoscope 1 back to its original position and then attach the outer sheath. Fold the outer sheath 101 back to its original position and pull it upwards to fit onto the outer wall of the insertion tube 1001. Then, the medical staff will put the locking ring 10102 on the end of the outer sheath 101 and lock the outer sheath 101 onto the insertion tube 1001 by adjusting the locking ring 10102 to prevent the outer sheath 101 from falling off during subsequent use. After the outer sheath 101 and inner sheath 104 are installed, the medical staff can use the endoscope to perform surgical treatment.

[0037] During the surgical procedure, the outer sheath 101 protects the insertion tube 1001 that enters the body, while the inner sheath 104 isolates the surgical instruments from the instrument channel 1003, thus preventing the insertion tube 1001 and instrument channel 1003 from contaminating human tissue. After the surgery, medical staff only need to remove the outer sheath 101 from the insertion tube 1001 and pull the inner sheath 104 out of the instrument channel 1003, and then perform a simple cleaning of the insertion tube 1001 and instrument channel 1003. There is no need for complex cleaning and disinfection of the endoscope, which solves the problem that frequent cleaning and disinfection operations in the existing technology can easily damage precision electronic components, leading to equipment failure and shortened service life, and also consume a lot of manpower, time and material resources, increasing the operating costs of medical institutions.

[0038] Furthermore, considering that during the process of medical personnel inserting sampling instruments such as forceps into the human body through the instrument channel 1003 of the endoscope to grasp the target tissue and then removing it through the instrument channel 1003, the grasped target tissue may collide with and come into contact with the inner wall of the instrument channel 1003, resulting in contaminants such as tissue debris, body fluids, and blood adhering to the inner wall of the instrument channel 1003; when the endoscope is used normally, the sealing rod 106 is not installed inside the inner sheath 104, at which time the external instruments can normally enter the human body through the inner sheath 104 for surgical treatment; and considering that the inner sheath 104 will connect the human body with the outside world, allowing external gases to enter the human body through the inner sheath 104, therefore, when the external instruments are not needed, medical personnel can use sterile cotton... An external sealing element or a flower is placed inside the through-slot 10701 to seal it, preventing external gas from entering the body through the inner sheath 104. During surgery, the inlet pipe 201 is connected to an external water pump. The instrument channel 1003 is fitted with an inner sheath 104, so tissue samples only come into contact with the inner sheath 104. After each tissue sample is taken, the medical staff removes the external instrument and inserts the sealing rod 106 into the inner sheath 104, allowing the sealing head 10602 to enter the inner sheath 104 and then into the clamping ring 105. The inner ring surface of the clamping ring 105 is an inverted conical surface, facilitating the insertion of the sealing head 10602. When the sealing head 10602 reaches the lower end of the clamping ring 105, as... Figures 4-7As shown: The sealing head 10602 will adhere to and be locked inside the clamping ring 105, sealing the clamping ring 105. At this time, the connecting sleeve 10601 will also be inserted into the through groove 10701, making the connecting sleeve 10601 connected to the inner sheath 104. Then, the sealing rod 106 cannot be inserted further. The sealing rod 106 is made of nickel-titanium alloy, which has excellent bending recovery performance and can pass smoothly through the instrument channel 1003 without easily getting stuck, deformed or broken. Then, the medical staff can start the external water pump to deliver saline into the inlet tube 201. The saline will enter the outlet tank 10201 through the connecting groove 10101, and then flow to the connection end between the clamping ring 105 and the inner sheath 104. The connection end between the clamping ring 105 and the inner sheath 104 is made of rubber. Therefore, the saline solution flowing to the connection end between the compression ring 105 and the inner sheath 104 will squeeze the compression ring 105, thereby squeezing the rubber end 10501 that is in contact with the inner sheath 104 inwards, causing the rubber end 10501 to separate from the inner sheath 104. Then, the saline solution can flow into the inner sheath 104. After the saline solution squeezes the rubber end 10501 inwards, the rubber end 10501 will be pressed against the sealing head 10602. At this time, the other end of the sealing rod 106, namely the connecting sleeve 10601, is fixedly connected to the protective sleeve 107. Therefore, after the sealing head 10602 is compressed, the sealing rod 106 will not move. Thus, the saline solution squeezes the rubber end 10501, causing the rubber end 10501 to be pressed against the inner sheath 104. End 10501 is pressed tightly against the outer surface of sealing head 10602, further improving the sealing effect of sealing head 10602 on compression ring 105. Therefore, the saline solution entering the inner sheath 104 will not flow from the sealed compression ring 105 into the human body, but will be discharged outward from the other end of the inner sheath 104, thereby cleaning the inner wall of the inner sheath 104 and preventing a large amount of saline solution from entering the human body and causing harm to the patient. Then, medical staff only need to insert a drainage tube into connecting sleeve 10601 to drain the saline solution in the inner sheath 104. During the cleaning process, the connecting wire on connecting sleeve 10601 is connected to an external power source, and the miniature vibration motor 202 on sealing rod 106 is started during the cleaning process. The vibration can be transmitted along sealing rod 106. The saline solution inside the inner sheath 104 is subjected to high-frequency agitation, creating a vibration cleaning effect that significantly improves the ability to remove dirt from the inner wall. After cleaning, an external air pump is connected to the inlet pipe 201, and then clean compressed air is delivered to the inlet pipe 201. The clean compressed air is then blown into the inner sheath 104 to purge it and remove any residual saline solution, ensuring that there is no liquid residue inside the inner sheath 104 to avoid affecting subsequent surgical procedures. Furthermore, the inner sheath 104 is made of silicone, which has a flexible cushioning effect and can significantly reduce the transmission of vibration, so that the vibration is mainly concentrated in the area of ​​the inner sheath 104 and will not cause significant interference or damage to the endoscope body and its internal precision electronic components.This method allows for direct cleaning of the inner sheath 104 during surgery, solving the problem in existing technologies where the instrument channel 1003 cannot be directly cleaned during surgery or treatment. This prevents the use of forceps for subsequent sampling when multiple tissue samples are required, as they become contaminated with residual tissue from previous sampling. This cross-contamination of tissue samples from different sites can affect the accuracy of laboratory results, potentially misleading clinical diagnoses and posing safety risks to patient treatment.

[0039] The connector 10401 is made of medical-grade stainless steel.

[0040] In this embodiment, medical-grade stainless steel has good biocompatibility, corrosion resistance and a certain weight, which can not only meet the hygiene requirements of medical equipment, but also use its own weight to achieve the natural falling and positioning of the connector 10401 in the instrument channel 1003.

[0041] Wiping cotton is provided on the outside of the sealing head 10602.

[0042] In this embodiment, the saline solution entering the inner sheath 104 can penetrate and wet the wiping cotton on the outside of the sealing head 10602, thereby using the wiping cotton wetted with saline solution to wipe and clean the inner ring surface of the compression ring 105, solving the problem that the saline solution entering the inner sheath 104 cannot clean the inner ring surface of the compression ring 105.

[0043] It also includes a protective lens 103; the protective lens 103 is fixedly attached to the protective head 102; the protective lens 103 is attached to the camera 1002.

[0044] In this embodiment, the protective lens 103 is attached to the outside of the camera 1002, which can form a physical isolation and protection for the lens of the camera 1002, preventing body fluids, tissue debris and dirt from contaminating the lens during the operation, and at the same time preventing instruments from scratching or bumping and causing damage to the camera 1002.

[0045] The protective lens 103 is made of medical-grade high-transparency tempered glass.

[0046] In this embodiment, the medical high-transmittance tempered glass has the characteristics of high light transmittance and no image distortion, which does not affect the normal shooting and imaging of the camera 1002. The surface is easy to clean, and it has high strength, scratch resistance and wear resistance. It is suitable for repeated use in medical sterile environments and has a long service life.

[0047] Example 2: Based on Example 1, such as Figure 6 and Figure 7 As shown, it also includes limit rods 109; two limit rods 109 are fixedly connected to the entrance end of the instrument channel 1003.

[0048] Working principle of Example 2: To facilitate the connection between the connector 10401 and the connector 108, the inner sheath 104 needs to protrude significantly from the instrument channel 1003. However, this also results in a large amount of excess material in the inner sheath 104, which can lead to a loose state and affect the insertion of subsequent external instruments. Therefore, medical personnel can tighten the inner sheath 104 through the connector 108 and then lock the connector 108 onto the two limiting rods 109 to keep the inner sheath 104 taut at all times. This effectively avoids channel deformation caused by looseness and wrinkles in the sheath, ensuring that subsequent external instruments can be smoothly inserted and used.
