Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a mirror tube protection device for medical endoscopes. BACKGROUND

[0002] In the modern medical field, medical endoscopes are widely used in the diagnosis and treatment of various diseases, such as gastrointestinal endoscopy, laparoscopic surgery, etc. As an important component to ensure the normal operation of the endoscope and the safety of the patient, the performance of the mirror tube protection device is crucial. However, the current market mirror tube protection devices for medical endoscopes have many problems. First, the functions of the device are relatively scattered, and each functional module is independent of each other, resulting in a complex overall structure. This not only increases the size and weight of the device, but also makes the operation of medical staff during installation and use cumbersome, making it difficult to quickly and accurately complete device assembly and debugging, which seriously affects the efficiency of medical operations. At the same time, the complex structure also brings difficulties to the transportation and storage of the device, requiring more space, and during transportation, parts may be loose or damaged due to collision. Moreover, the assembly relationship of the parts of the existing device is not clear, and the coordination between the parts is poor, which makes the effect unstable when clamping and sealing the endoscope, and cannot effectively prevent liquid and gas leakage. In actual medical operations, leakage may cause infection in the surgical area, increase the risk of postoperative recovery of patients, and even cause serious complications. In addition, most endoscope protection devices have poor adaptability and are difficult to adapt to different types of endoscope heads. Hospitals often need to equip different types of endoscopes with multiple adapters, increasing the cost of equipment procurement and management. SUMMARY

[0003] In view of the deficiencies of the prior art, the present application provides a mirror tube protection device for medical endoscopes, which has the advantages of quick disassembly and multi-angle rotation, and solves the problems of being unable to match multiple types and being difficult to ensure sealing.

[0004] To solve the above technical problems, the present application provides the following technical solutions: The mirror tube protection device for medical endoscopes comprises a main body, wherein the main body is provided with a top clamping and universal structure and a multi-angle rotating structure. The top clamping and universal structure comprises a rotating compression ring threadedly connected with the main body, a combined component composed of a spring one clamped between a rotating compression ring upper cover and a compression ring movable block is sleeved on the rotating compression ring, a handle is arranged in the rotating compression ring, a spring two and a contact are arranged inside the handle, and an O-shaped sealing ring is arranged in a groove of the main body; and the circular hole of the rotating compression ring is centrally arranged in the inclined groove of the main body. The multi-angle rotating structure includes an outer tube welded to the main body, and the outer tube is sequentially covered with an angle color ring and a compression nut. The main body is covered with a rotating sealing ring, and two large O-rings are installed in the groove of the rotating sealing ring. The right water valve and the left water valve are installed on the rotating sealing ring, and the rotating sealing ring is locked on the main body by a conical compression nut.

[0005] Preferably, the main body is threadedly connected to the rotating clamping ring, and the rotating clamping ring is rotated clockwise to drive the clamping ring movable block to move downward. The top step of the clamping ring movable block presses the endoscope, and the O-ring inside the main body is deformed with the Luer connector at the front end of the endoscope to form a sealing ring.

[0006] Preferably, the top of the main body is a conical structure, which is larger than the head of the endoscope.

[0007] Preferably, a spring is provided between the upper cover of the rotating pressing ring and the movable block of the pressing ring, and the contact inside the handle pops out when the rotating pressing ring rotates to the bottom and falls into the corresponding circular groove of the main body.

[0008] Preferably, a 0.1mm gap is reserved after the rotating sealing ring and the main body are assembled and locked with the conical compression nut. The O-rings at the front and rear ends of the rotating sealing ring are deformed after assembly to seal the main body and the rotating sealing ring. The water outlet of the main body is located in the middle of the rotating sealing ring, and the main body has reserved notches for water overflow around it.

[0009] Preferably, the handle provided in the rotating clamping ring is screwed onto the rotating clamping ring, and the spring 2 and the contact placed inside the handle cooperate with the rotating clamping ring to achieve locking and anti-accidental collision functions.

[0010] Preferably, after the right water valve and the left water valve are installed on the rotating sealing ring, the rotating sealing ring is rotated, and water can flow in and out from the water outlet of the main body through the middle of the rotating sealing ring and through the water valve, and when the operation is blocked by the water valve, the operating angle can be adjusted by rotating the rotating sealing ring.

[0011] Preferably, a spring 1 between the rotating clamping ring upper cover and the clamping ring movable block is used for telescopic adjustment to compensate for the excess size of the front section caused by the size difference between the main body and the endoscope head, and at the same time generates downward pressure to assist in locking the endoscope.

[0012] Preferably, the outer tube is sequentially covered with an angle color ring and a compression nut, the angle color ring is used to indicate the rotation angle, and the compression nut is used to fix the relative position of the outer tube and the main body.

[0013] By means of the above technical solution, the present invention provides a tube protection device for a medical endoscope, which has at least the following beneficial effects: 1. This tube protection device for medical endoscopes rotates the clamping ring clockwise, causing it to move downward along the threads, driving the clamping ring's movable block to move downward synchronously. The stepped design at the top of the clamping ring's movable block allows it to fit tightly against the endoscope, forming the first physical seal. Simultaneously, the O-ring inside the main body deforms under pressure upon contact with the Luer connector at the front end of the endoscope, forming a sealing ring that effectively prevents water and air leaks, greatly improving the device's sealing performance.

[0014] 2. The scope tube protection device for medical endoscopes, when the rotary clamping ring is rotated to the bottom, the contact inside the handle pops out under the action of the mechanical structure and falls accurately into the corresponding circular groove of the main body. On the one hand, after the contact falls into the circular groove, the operator can intuitively understand that the device has completed the locking operation through obvious mechanical feedback or visual prompts, which serves as a clear locking prompt; on the other hand, during normal use of the device, if it is accidentally bumped or subjected to slight external force, the rotary clamping ring will not easily rotate counterclockwise, because in order to make the contact pop up from the groove, a greater external force needs to be provided, thereby ensuring that the endoscope is firmly connected during use.

[0015] 3. The scope tube protection device for medical endoscopes adopts a conical structure on the top of the main body, which is slightly larger than the endoscope head, reserving space for adapting to different models of endoscopes. At this time, the spring 1 between the rotating clamping ring cover and the clamping ring movable block plays a key role. The spring 1 has a telescopic adjustment function and can be adaptively adjusted according to the difference in the size of the endoscope head to compensate for the excess size of the front section. During the clamping process, the downward pressure generated by the spring 1 will further enhance the locking effect, ensuring that different models of endoscopes can be tightly connected to the equipment, significantly improving the versatility of the equipment. The hospital does not need to equip different models of endoscopes with a variety of adapter devices, reducing equipment procurement and management costs, and also facilitating medical staff to quickly replace different models of endoscopes during operation, thereby improving work efficiency.

[0016] 4. This tube protection device for medical endoscopes has a 0.1mm gap reserved after the rotating sealing ring and the main body are assembled and locked with a conical compression nut, providing smooth rotation conditions for the equipment. The operator can rotate the rotating sealing ring according to actual operation needs to achieve multi-angle rotation of the equipment. The O-rings assembled at the front and rear ends of the rotating sealing ring will deform after installation, forming a sealing barrier to seal the main body and the rotating sealing ring, ensuring that water will not leak even during rotation.

[0017] 5、The mirror tube protection device for medical endoscope, the water outlet of the main body is located in the middle of the rotating sealing ring, and the main body is reserved with a notch to facilitate the overflow of water flow from all around. Combined with the sealing structure formed by the large deformation of the O-shaped sealing ring in the rotating sealing ring, it is ensured that the water flow can normally enter and exit from the water valve when the rotating sealing ring is rotated. This device can maintain the stable supply of water flow during medical operation regardless of the rotation of the device, and will not interrupt or affect the flow and pressure of the water flow due to the rotation operation. Even when the line of sight or operation is blocked due to the position of the water valve, the operator can rotate the valve body, adjust the operation angle, and still ensure the stable supply of water flow, providing a strong guarantee for the smooth operation of medical operation.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0021] Some embodiments of the mirror tube protection device for medical endoscope provided by the present application will be described below in combination with the drawings.

[0022] Embodiment one: Currently, medical endoscope tube protection devices have problems such as dispersed functions and complex structures, which make installation and use inconvenient, and transportation and storage difficult. Therefore, the tube protection device for a medical endoscope provided by the present invention includes a main body 9, which is provided with a top clamping and universal structure and a multi-angle rotation structure. By integrating the two core functions into the main body 9, the device structure is made compact, component redundancy is reduced, and medical staff can quickly install and use it during medical operations. It also facilitates the transportation, storage and maintenance of the device.

[0023] The assembly relationship of parts of existing medical endoscope protection equipment is unclear, the coordination of various components is poor, and the clamping and sealing effects are unstable. In order to solve the above problems, the top clamping and universal structure includes a rotating clamping ring 4 threadedly connected to the main body 9, and the rotating clamping ring 4 is provided with a combination composed of a rotating clamping ring upper cover 1 and a clamping ring movable block 3 with a spring 2 sandwiched in the middle. A handle 7 is provided inside the rotating clamping ring 4, and a spring 2 6 and a contact 5 are placed inside the handle 7, and a small O-ring 8 is placed in the groove of the main body 9; the circular hole of the rotating clamping ring 4 is centered with the oblique groove of the main body 9; the clear assembly relationship and position setting of parts ensure that the various components can work together during work, lay the foundation for achieving reliable clamping and sealing functions, ensure stable equipment performance, and improve reliability and safety of use.

[0024] Previous endoscope protection devices had inflexible viewing angle adjustment, and water was prone to leaking during rotation, affecting operation. Therefore, the multi-angle rotating structure includes an outer tube 17 welded to the main body 9. The outer tube 17 is sequentially covered with an angle color ring 10 and a compression nut 11. A rotating sealing ring 15 is provided on the main body 9. Two large O-rings 12 are installed in the groove of the rotating sealing ring 15. The right water valve 13 and the left water valve 14 are installed on the rotating sealing ring 15, and the rotating sealing ring 15 is locked to the main body 9 by a conical compression nut 16. The component composition and connection method of the multi-angle rotating structure provide the endoscope with flexible viewing angle adjustment capabilities during medical operations, allowing doctors to quickly adjust the angle of the endoscope according to different surgical sites and patient conditions, thereby improving the accuracy and efficiency of surgical operations. At the same time, the sealing design ensures the normal operation of the water flow system during rotation.

[0025] The existing equipment has a single sealing method, poor sealing effect, and is prone to liquid and gas leakage. In order to solve the above problems, the main body 9 is threadedly connected to the rotary clamping ring 4, and the rotary clamping ring 4 is rotated clockwise to drive the clamping ring movable block 3 to move downward. The top step of the clamping ring movable block 3 presses the endoscope, and the O-ring 8 inside the main body 9 and the Luer connector at the front end of the endoscope are deformed to form a sealing ring. The threaded drive and mechanical compression cooperate with the deformation of the sealing ring to achieve a tight seal on the endoscope, effectively prevent liquid and gas leakage, avoid the risk of infection caused by leakage during surgery, provide a safe environment for medical operations, and ensure patient safety.

[0026] Most endoscope protection devices have poor adaptability and are difficult to be compatible with different models of endoscope heads. Therefore, the top of the main body 9 is a conical structure that is larger than the endoscope head. Advantages: The conical structure design expands the compatibility of the device with different models of endoscope heads, allows a certain dimensional error, and enables the device to adapt to endoscopes of various specifications, reducing the cost of hospitals purchasing multiple adapters for different endoscope models, while improving the versatility and convenience of the device.

[0027] Example 2: Existing equipment cannot automatically adapt to endoscopes of different sizes and lacks locking prompts. In order to solve the above problems, combined with Figure 2 As shown, on the basis of Example 1, a spring 2 is provided between the rotary clamping ring upper cover 1 and the clamping ring movable block 3. The contact 5 inside the handle 7 pops out when the rotary clamping ring 4 rotates to the bottom and falls into the corresponding circular groove of the main body 9. The spring 2 can be telescopically adjusted according to the size difference of the endoscope head, automatically compensating for the excess size of the front section, and ensuring that a good clamping force can always be provided for endoscopes of different sizes; the pop-up and positioning function of the contact 5 not only provides the operator with a clear locking reminder, but also prevents the equipment from loosening due to accidental collisions, etc., ensuring that the endoscope is stably connected during the operation and ensuring the smooth progress of the operation.

[0028] In the past, the sealing effect of the equipment was poor when rotating, and the water flow was easily interrupted. Therefore, specifically, a 0.1mm gap is reserved after the rotating sealing ring 15 and the main body 9 are assembled and locked with the conical compression nut 16. The O-rings 12 at the front and rear ends of the rotating sealing ring 15 are deformed after assembly to seal the main body 9 and the rotating sealing ring 15. The water outlet of the main body 9 is located in the middle of the rotating sealing ring 15. The main body 9 reserves notches for water overflow on all sides. The 0.1mm gap ensures that the rotating sealing ring 15 can rotate flexibly and realize the multi-angle rotation function without affecting the sealing performance due to excessive gaps. The deformation seal of the sealing ring and the special water flow channel design ensure that the water flow can be stable during the rotation process, and the water flow will not be interrupted or leaked due to the rotation operation, providing stable water flow support for medical operations and maintaining the cleanliness of the operating area and a clear field of vision.

[0029] The existing equipment has a single locking function and is easily loosened by external interference. Therefore, the handle 7 set in the rotary clamping ring 4 is screwed onto the rotary clamping ring 4, and the spring 2 6 and contact 5 placed inside the handle 7 cooperate with the rotary clamping ring 4 to achieve locking and anti-accidental collision functions. The handle 7 cooperates with the internal spring 2 6 and contact 5 to form a double locking guarantee mechanism. The spring 2 6 provides a certain buffering and reset capability. The locking effect of the contact 5 enhances the stability of the equipment after locking, effectively avoiding the loosening of the equipment due to external interference during medical operations, and improving the safety and reliability of the equipment.

[0030] Example 3: The water flow control and viewing angle adjustment of traditional equipment are independent of each other and the operation is cumbersome. Figure 2 As shown, on the basis of Example 1, after the right water valve 13 and the left water valve 14 are installed on the rotating sealing ring 15, the rotating sealing ring 15 is rotated, and water can flow in and out from the water outlet of the main body 9 through the middle of the rotating sealing ring 15 through the water valve, and when the operation is blocked by the water valve, the operating angle of view can be adjusted by rotating the rotating sealing ring 15. The combined design of the water valve and the rotating sealing ring 15 integrates the water flow control and angle adjustment functions. The doctor can simultaneously realize water flow adjustment and angle conversion without additional complex operations during the operation, which improves the convenience and fluency of the surgical operation, helps to shorten the operation time and improve the quality of the operation.

[0031] The existing equipment has poor adaptation effect to endoscopes of different specifications and the clamping force is unstable. In order to solve the above problems, a spring 2 is provided between the rotating clamping ring upper cover 1 and the clamping ring movable block 3, which is used for telescopic adjustment to compensate for the excess size of the front section caused by the size difference between the main body 9 and the endoscope head, and at the same time generates downward pressure to assist in locking the endoscope. The dual action mechanism of spring 2 not only realizes adaptive adjustment to endoscopes of different specifications, but also enhances the clamping force, ensuring that no matter how the size of the endoscope changes, it can be tightly connected to the equipment, thereby improving the versatility and stability of the equipment and reducing the surgical risks caused by adaptation problems.

[0032] In the past, the angle adjustment of the equipment lacked precise reference and the structural stability was insufficient. Therefore, the outer tube 17 was sequentially covered with an angle color ring 10 and a tightening nut 11. The angle color ring 10 is used to indicate the rotation angle, and the tightening nut 11 is used to fix the relative position of the outer tube 17 and the main body 9. The angle color ring 10 provides an intuitive reference for the doctor when adjusting the angle of the endoscope, making the angle adjustment more precise and helping the doctor to locate the surgical site more accurately; the tightening nut 11 ensures a firm connection between the outer tube 17 and the main body 9, maintains structural stability during multi-angle rotation, ensures the overall performance of the equipment is reliable, and provides stable support for medical operations.

[0033] Through the above embodiment, it can be known that: the rotary pressure ring cover 1, spring 1 2, and pressure ring movable block 3 are assembled in sequence, and the three are combined and sleeved on the rotary pressure ring 4; spring 2 6 and contact 5 are placed inside the handle 7; the small O-ring 8 is placed in the groove of the main body 9; the rotary pressure ring 4 is screwed onto the main body 9 according to the thread definition position, so that the circular hole of the rotary pressure ring 4 is centered with the inclined groove of the main body 9, and then the handle 7 is screwed onto the rotary pressure ring 4; the main body 9 is welded to the outer tube 17, and the angle color ring 10 and the pressure nut 11 are put on in sequence; two large O-rings 12 are installed in the groove of the rotary sealing ring 15, the right water valve 13 and the left water valve 14 are installed on the rotary sealing ring 15, and then the rotary sealing ring 15 is sleeved on the main body 9 and locked with the conical pressure nut 16. When in use, the rotating clamping ring 4 is rotated clockwise, and it moves downward along the thread to drive the clamping ring movable block 3 to move downward. The top step of the clamping ring movable block 3 presses the endoscope, and at the same time, the O-ring 8 inside the main body 9 and the Luer connector at the front end of the endoscope are deformed under pressure to form a sealing ring; when the rotating clamping ring 4 is rotated to the bottom, the contact 5 in the handle 7 pops out and falls into the corresponding circular groove of the main body 9 to prompt locking and prevent accidental contact and rotation; with the help of the conical structure at the top of the main body 9 and the telescopic adjustment of the spring 2 between the rotating clamping ring upper cover 1 and the clamping ring movable block 3, it is suitable for different endoscope heads; when the viewing angle needs to be adjusted, the rotating sealing ring 15 is rotated, and the 0.1mm gap reserved for assembly with the main body 9 is used to achieve multi-angle rotation, the O-ring 12 inside the rotating sealing ring 15 is deformed and sealed, and the water outlet of the main body 9 is located in the middle of the rotating sealing ring 15, and the overflow tank design is used to ensure that water flows in and out of the water valve normally during rotation.

[0035] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
