AI Technical Summary
Laparoscopic lenses are prone to getting bloodstains during use, causing them to become blurry. They need to be removed and wiped frequently, which affects the surgical field of vision and increases the risk of infection. In addition, temperature differences can cause fogging, prolonging the operation time.
An automatic wiper for laparoscopic lenses was designed, comprising a baffle plate, a medical sponge, a catheter, a water bladder, a brush, and a micro motor. The brush cleans the lens by means of an electric telescopic rod, water injection through the catheter, and toothed blocks. Combined with spring buffering and the catheter opening up the tissue, it can achieve cleaning without removing the lens.
This allows for cleaning without removing the lens during surgery, avoiding obstruction of the field of vision and leakage of bodily fluids, shortening surgical time, and reducing the risk of infection.

Abstract
Description
Technical Field
[0001] This invention relates to the field of laparoscopic surgery technology, specifically to an automatic windshield wiper for a laparoscopic lens. Background Technology
[0002] Laparoscopic surgery is a newly developed minimally invasive method and an inevitable trend in the future development of surgical methods. With the rapid advancement of industrial manufacturing technology and the integration of related disciplines, a solid foundation has been laid for the development of new technologies and methods. In addition, the increasingly skilled operation of doctors has led to the replacement of many open surgeries with endoscopic surgeries, greatly increasing the surgical options available.
[0003] However, when using a laparoscope, the lens needs to be inserted into the patient's body, and the lens surface will become stained with blood, causing the lens to become blurry and the surgical field of vision to be unclear. At this time, the laparoscope needs to be taken out and wiped clean. After wiping, it needs to be inserted back into the patient's body. However, the surgical operation must be paused when taking it out and wiping it. It can only resume after the laparoscope is cleaned and put back into the body. Moreover, due to the temperature difference between the outside and inside the body, even if the laparoscope is cleaned outside, the lens surface will fog up when it is put back into the body due to the temperature difference. It often needs to be taken out and wiped repeatedly. This undoubtedly delays the operation time. In addition, during the operation, the patient's body tissue will also obstruct the lens, and the patient's blood and body fluids can easily seep out from the surgical incision, causing contamination. Summary of the Invention
[0004] The purpose of this invention is to provide an automatic wiper for laparoscopic lenses to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic wiper for a laparoscopic lens, comprising a laparoscopic rod, a lens connected to the left end surface of the laparoscopic rod, and a connecting ring sleeved on the outer surface of the lens. A baffle plate is sleeved on the outer surface of the laparoscopic rod. A medical sponge is adhered to the surface of the baffle plate near the laparoscopic rod. A conduit extends through both the upper and lower ends of the baffle plate. A water inlet is located at the right end of the conduit, and a water bladder is connected to the left end of the conduit. The water bladder is wrapped around the outer surface of the connecting ring, and a [missing information - likely a design feature] is located on the left end surface of the connecting ring. The first recess has evenly distributed serrated protrusions on its inner wall. A toothed block is provided inside the first recess and meshes with the inner wall of the first recess. A micro motor is connected to the left end surface of the toothed block, and a connecting block is connected to the outer surface of the micro motor. A connecting plate with an L-shaped longitudinal section is connected to the left end surface of the connecting block. A brush that fits against the left end surface of the lens is provided at the bottom of the connecting plate. An electric telescopic rod is connected to the right end surface of the barrier plate, and a fixing ring that fits onto the outer surface of the laparoscopic rod is connected to the right end of the electric telescopic rod.
[0006] Preferably, an inner cavity is provided at the middle position of the connecting ring, and the diameter of the inner cavity is the same as the diameter of the lens.
[0007] Preferably, springs are symmetrically connected to the right end surface of the connecting ring, and the right end of the springs is connected to the barrier plate.
[0008] Preferably, the longitudinal section of the first notch is annular, and a second notch is provided inside the first notch on the connecting ring. A limiting block is engaged inside the second notch, and the left end of the limiting block is connected to the toothed block.
[0009] Preferably, the top of the connecting plate is provided with a groove structure, a battery box is inserted inside the groove structure, the outer surface of the battery box is provided with a thread structure, and the right end of the battery box is connected to the connecting block.
[0010] Preferably, a mounting plate is connected to the left end surface of the brush, and the mounting plate is engaged inside the connecting plate.
[0011] Preferably, a first magnet is connected to the left end surface of the mounting plate, a first iron plate connected to the inner wall of the connecting plate is connected to the left end surface of the first magnet, a second insert is inserted through the top of the mounting plate, a lever protruding outside the mounting plate is connected to the right end surface of the second insert, a second magnet is connected to the top end of the second insert, and a second iron plate connected to the inner wall of the connecting plate is connected to the top end of the second magnet.
[0012] Preferably, a battery compartment is provided on the right end surface of the fixing ring, and fixing bolts are inserted at both the upper and lower ends of the fixing ring, with the inner end of the fixing bolt penetrating the interior of the laparoscopic rod.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. This automatic wiper for laparoscopic lenses features a baffle plate with a medical sponge attached. During surgery, the baffle plate moves along the laparoscopic rod via an electric telescopic rod, allowing the medical sponge to seal the surgical incision on the patient's body, thus preventing the leakage of blood and bodily fluids and causing contamination.
[0015] 2. The automatic wiper of this laparoscopic lens is equipped with a spring. The two ends of the spring are connected to the connecting ring and the baffle plate respectively. When the baffle plate moves, the elastic force of the spring resists the movement, allowing the baffle plate to move slowly. This prevents the baffle plate from moving a large distance at once and avoids damage to the incision site.
[0016] 3. This laparoscopic lens features an automatic wiper system. By using a catheter and a water bladder, water is injected through the catheter into the water bladder. The water bladder then inflates, expanding the patient's internal tissues and preventing the lens from being obstructed, thus ensuring an unobstructed view during surgery.
[0017] 4. This laparoscopic lens automatic wiper is equipped with a brush mounted on a connecting plate. The connecting plate is connected to a toothed block. When the toothed block is rotated by a micro motor, it will make a circular motion on the connecting ring. At the same time, the connecting plate will also make a circular motion synchronously through the rotation of the toothed block. Thus, the brush rotates to clean the surface of the lens, removing contaminants or water mist attached to the lens surface, ensuring that the field of vision is not obstructed during surgery.
[0018] 5. The automatic wiper for this laparoscopic lens, through the above-mentioned series of structures, allows the lens to be cleaned without removing the patient during laparoscopic surgery, and can prevent the patient's internal tissues from obstructing the lens's field of view, while also preventing blood and body fluids from seeping out of the incision site.

[0029] Example 1
[0030] like Figure 1-5As shown, the automatic wiper for a laparoscopic lens in this embodiment includes a laparoscopic rod 1, a lens 2 connected to the left end surface of the laparoscopic rod 1, and a connecting ring 3 sleeved on the outer surface of the lens 2. A baffle plate 6 is sleeved on the outer surface of the laparoscopic rod 1, and the baffle plate 6 can slide freely on the laparoscopic rod 1. A medical sponge 7 is attached to the end surface of the baffle plate 6 near the laparoscopic rod 1. The baffle plate 6 contacts the skin at the patient's abdominal incision site, thereby blocking it and preventing the leakage of internal body fluids and blood through the medical sponge 7. The baffle plate 6 has catheters 8 penetrating both the upper and lower ends. The catheters 8 are telescopic flexible tubes. The right end of the conduit 8 has a water inlet 9, through which an external pipe can be connected to inject water into the conduit 8. The left end of the conduit 8 is connected to a water bladder 10. Water enters the water bladder 10 through the conduit 8, causing the water bladder 10 to inflate and expand the internal tissues of the human body, allowing the lens 2 to perform better imaging inspection. The water bladder 10 wraps around the outer surface of the connecting ring 3. The left end surface of the connecting ring 3 has a first recess 11. The inner wall of the first recess 11 has evenly distributed serrated protrusions. The first recess 11 has a toothed block 14 inside, which is completely recessed inside the first recess 11. Block 14 engages with the inner wall of the first recess 11, allowing the toothed block 14 to rotate on the connecting ring 3. A micro motor 15 (model Y90S-2) is connected to the left end surface of the toothed block 14, controlling its rotation. A connecting block 16 is connected to the outer surface of the micro motor 15, ensuring stable installation. A connecting plate 18 with an L-shaped longitudinal section is connected to the left end surface of the connecting plate 16. A brush 20, with a length equal to the radius of the lens 2, is located at the bottom of the connecting plate 18 and fits against the left end surface of the lens 2. The connecting plate 18 securely connects the brush 20, which contacts the surface of the lens 2. This allows the brush 20 to clean the surface of the lens 2 during the circular motion of the toothed block 14. An electric telescopic rod 27 is connected to the right end of the barrier plate 6. The electric telescopic rod 27 can control the movement of the barrier plate 6 on the laparoscopic rod 1 by extending and retracting. A fixing ring 28, fitted onto the outer surface of the laparoscopic rod 1, is connected to the right end of the electric telescopic rod 27. The fixing ring 28 is firmly connected to the laparoscopic rod 1, ensuring that the connecting ring 3 and the barrier plate 6, among other structures, can be stably installed on the laparoscopic rod 1.
[0031] Specifically, an inner cavity 4 is provided in the middle of the connecting ring 3. The diameter of the inner cavity 4 is the same as the diameter of the lens 2, so that the lens 2 can pass through the connecting ring 3 to perform video inspection of the human body.
[0032] Furthermore, springs 5 are symmetrically connected to the right end surface of the connecting ring 3. The right end of the spring 5 is connected to the barrier plate 6. Through the elasticity of the spring 5 itself, the electric telescopic rod 27 can make the barrier plate 6 move slowly when it pushes it, so as not to cause damage to the patient's surgical incision by moving a large distance at one time.
[0033] Furthermore, the longitudinal section of the first notch 11 is annular, and the interior of the first notch 11 is provided with a second notch 12 opened on the connecting ring 3. The interior of the second notch 12 is engaged with a limiting block 13, and the left end of the limiting block 13 is connected to the toothed block 14. Through the engagement of the limiting block 13 and the second notch 12, the toothed block 14 will not fall out of the interior of the first notch 11.
[0034] Furthermore, the top of the connecting plate 18 is provided with a groove structure, and the battery box 17 is inserted inside the groove structure. The outer surface of the battery box 17 is provided with a thread structure. The right end of the battery box 17 is connected to the connecting block 16. The battery box 17 is connected to a battery that provides power to the micro motor 15. The structure of the battery box 17 makes it easy to assemble and disassemble from the connecting plate 18, thereby facilitating the user to replace the battery.
[0035] Furthermore, a mounting plate 19 is connected to the left end surface of the brush 20. The mounting plate 19 is engaged inside the connecting plate 18, so that the brush 20 is stably mounted on the connecting plate 18 through the mounting plate 19.
[0036] Furthermore, a first magnet 21 is connected to the left end surface of the mounting plate 19, and a first iron plate 22 connected to the inner wall of the connecting plate 18 is connected to the left end surface of the first magnet 21. A second insert rod 23 is inserted through the top of the mounting plate 19, and a lever 24 protruding from the outside of the mounting plate 19 is connected to the right end surface of the second insert rod 23. A second magnet 25 is connected to the top of the second insert rod 23, and a second iron plate 26 connected to the inner wall of the connecting plate 18 is connected to the top of the second magnet 25. This ensures a stable connection between the connecting plate 18 and the mounting plate 19, and also facilitates disassembly for cleaning or replacement of the brush 20.
[0037] The usage method of this embodiment is as follows: Medical personnel connect the mounting plate 19 and the connecting plate 18. At this time, the first magnet 21 and the first iron piece 22 are attracted to each other. Then, the lever 24 is slid to make the second insert 23 slide out. At this time, the second magnet 25 and the second iron piece 26 are attracted to each other, thereby making the brush 20 stably installed. Then, gas is injected into the patient's body through the injection tool to make the internal and external air pressure the same. Then, the lens 2 is inserted into the body through the incision of the patient's body for examination. At this time, the medical sponge 7 is sealed by the sliding of the barrier plate 6 to prevent the patient's body fluids and blood from seeping out. If the examination is blocked by internal tissue, water can be injected into the water bag 10 through the catheter 8 to expand it and open up the patient's internal tissue for examination. If the surface of the lens 2 is contaminated, the button connected to the right end of the laparoscopic rod 1 and the wire of the micro motor 15 can be pressed to make the micro motor 15 drive the tooth block 14 to rotate. At this time, the mounting plate 19 will drive the brush 20 to make a circular motion, thereby removing the contaminants from the surface of the lens 2.
[0038] Example 2
[0039] The structure of the automatic windshield wiper for the laparoscopic lens in this embodiment is basically the same as that in Embodiment 1. The difference is that a battery compartment 29 is provided on the right end surface of the fixing ring 28, and fixing bolts 30 are inserted at both the upper and lower ends of the fixing ring 28. The inner ends of the fixing bolts 30 penetrate the interior of the laparoscopic rod 1, which facilitates the disassembly and assembly of the fixing ring 28 and also provides power to the electric telescopic rod 27 (see...). Figure 6 ).
[0040] The method of use in this embodiment is as follows: the fixing bolt 30 is used to stably connect the fixing ring 28 to the laparoscope rod 1, thereby allowing the connecting ring 3 and the barrier plate 6 to be stably connected to the laparoscope rod 1, ensuring the stability of the overall structure. The fixing bolt 30 also facilitates the subsequent disassembly of the laparoscope rod 1 and the fixing ring 28, allowing the laparoscope to be separated from other structures for easy maintenance, cleaning and disinfection. At the same time, the battery compartment 29 provides power to the electric telescopic rod 27. By pressing the button on the end face of the fixing ring 28, the electric telescopic rod 27 can be made to work stably.
[0041] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
