Description

Technical Field

[0001] The invention relates to the field of surgical instruments, in particular to an automatic cleaning device for a thoracoscope. Background Art

[0002] Thoracoscopic, laparoscopic, and arthroscopic surgeries are among the most commonly used medical procedures. They address the existing challenges of large incisions, severe postoperative pain, and delayed recovery. By making a minimally invasive incision on the patient's surface and inserting a laparoscopic device into the body through this incision, the surgical site can be monitored and magnified in real time. This reduces the size of the incision and allows for real-time magnification of the surgical image, facilitating the surgical procedure. However, a problem with existing surgical procedures is that the laparoscope lens is easily contaminated during surgery, which can affect the surgical image and require frequent cleaning. Repeated removal from the incision can cause repeated friction and infection. To improve surgical efficiency and minimize tedious procedures, there is an urgent need to develop a device that is non-invasive to the patient's surgical incision and facilitates cleaning of the laparoscope lens. Existing medical devices are highly sophisticated, making it difficult to perform real-time lens cleaning within the body. Therefore, a sheath is fixed at the patient's surgical incision, and the thoracoscope is inserted from the sheath into the surgical site to provide real-time image feedback of the surgical position. Once the lens is contaminated, the thoracoscope is removed from the sheath, cleaned, wiped, and disinfected, and then inserted into the chest cavity from the sheath again to resume work. The disadvantage of this operation method is that the laparoscope needs to be repeatedly inserted and removed for cleaning and wiping, which is cumbersome to operate. In addition, the laparoscope is easily contaminated when it comes into contact with the external environment, and contaminants can easily enter the chest or abdominal cavity from the working pipe of the sheath, which can easily cause infection. Therefore, it is urgent to develop a cleaning device that can automatically clean and disinfect the lens without completely removing the thoracoscope or laparoscope from the working cavity.

DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] like Figure 1-4As shown, the present invention includes a thoracoscope 3 and a matching automatic cleaning fixed sheath device. The automatic cleaning fixed sheath device includes a fixed sheath 5 and an automatic cleaning assembly disposed within the fixed sheath 5. The fixed sheath 5 has a tubular working channel 8 in the middle, and the automatic cleaning assembly is disposed within the tubular working channel 8. The front end of the thoracoscope 3 is a lens 7, and the rear end is a handle connection end 2 for the thoracoscope 3. A cold light source connection port 1 is also provided on the side of one end near the handle connection end 2. After the cold light source connection port 1 is connected to a cold light source, it provides light for the lens 7 of the thoracoscope 3. The lens 7 extends into the chest cavity through the tubular working channel 8 of the fixed sheath 5, and the lens 7 of the thoracoscope 3 can be directly inserted into or withdrawn from the tubular working channel 8 of the fixed sheath 5. The handle and cold light source are conventional handles and conventional cold light sources used for thoracoscopes 3, laparoscopes, and endoscopes. During surgery, the cold light source is connected to the cold light source interface to provide light for the lens 7 and power for the anti-fog heating device 24. The specific connection method is the same as that of existing laparoscopes, thoracoscopes 3, and endoscopes.

[0035] In this embodiment, the fixed sheath 5 includes an incision insertion end 13, an incision external fixing end 12, and a lens insertion end 9. The incision external fixing end 12 is located above the incision insertion end 13, and the lens insertion end 9 is located above the incision external fixing end 12. The interior of the fixed sheath 5 is a hollow, tubular working channel 8. The outer surface of the incision insertion end 13 is provided with an outwardly protruding external thread 14. The protruding external thread 14 on the outer surface of the incision insertion end 13 is a right-handed thread. When securing the fixed sheath 5, the right-handed thread is screwed into the incision 6 in a clockwise manner, consistent with the normal rotation operation. After screwing in, the incision external fixing end 12 abuts against the outside of the incision 6, preventing the entire fixed sheath 5 from being accidentally screwed into the incision 6. The fixed sheath 5 can be fixed in the incision 6 without slipping.

[0036] In this embodiment, the end of the lens 7 of the thoracoscope 3 is tilted, with the slope 25 of the tilted portion facing away from the cold light source connection port 1. An anti-fog heating device 24 is provided around the end of the lens 7 of the thoracoscope 3. During actual operation, this structural design ensures that the cold light source connection port 1 faces upward, and wiring will not affect the surgical site. The lens 7 has an inclined slope 25. After insertion into the chest cavity, the slope 25 of the lens 7 is tilted from top to bottom and aligned with the organ undergoing surgery, providing a relatively wide and unobstructed field of view. During surgery, the lens surface is prone to fogging due to the temperature difference between body temperature and the surgical instruments. When fogging occurs, simply powering on the anti-fog heating device 24 can achieve defogging of the lens surface. The power for the anti-fog heating device can be supplied through the connected cold light source connection port.

[0037] In this embodiment, the automatic cleaning assembly includes a cleaning assembly base 4 and a cleaning device mounted on the cleaning assembly base 4. The cleaning assembly base 4 is mounted within the tubular working channel 8 and is in contact with the inner wall of the tubular working channel 8. A working channel is provided in the center of the cleaning assembly base 4 for the passage of the thoracoscope 3. The cleaning device includes a cleaning liquid injection tube 20, a disinfectant injection tube 19, and a waste liquid negative pressure recovery tube 26, all mounted within the cleaning assembly base 4. The present invention separates the automatic cleaning device from the thoracoscope for ease of manufacture. Thoracoscopes are typically standard medical devices. If the cleaning device were mounted directly on the thoracoscope, it would be inconvenient to manufacture and would not meet the standards of standard medical devices. Furthermore, if any component were damaged, the entire thoracoscope would cease to function properly, resulting in high replacement costs. This independent automatic cleaning assembly not only facilitates manufacture, reducing production costs, but also facilitates disassembly, facilitating subsequent cleaning and disinfection of the medical device.

[0038] In this embodiment, the lower end of the outlet of the cleaning liquid injection pipe 20 is a cleaning nozzle 22, which is arranged at the lower end of the cleaning component base 4. The outlet of the cleaning nozzle 22 is inclined upward. When the cleaning nozzle 22 is working, the cleaning liquid sprayed can be directly sprayed onto the slope 25 of the lens 7 of the thoracoscope 3, so as to facilitate the flushing of dirt on the surface of the lens 7; the lower end of the outlet of the disinfectant injection pipe 19 is a disinfectant nozzle 21, which is located above the cleaning nozzle 22. The outlet end of the disinfectant nozzle 21 can drain the disinfectant to the bottom of the thoracoscope 3. end, flush and disinfect the lower end of the entire thoracoscope 3; and the lower end of the waste liquid negative pressure recovery pipe 26 is provided with an elbow 23, which extends below the cleaning component base 4, and the waste liquid negative pressure recovery pipe 26 is not fixed to the cleaning component base 4, and can be extended and retracted up and down relative to the cleaning component base 4, or the elbow 23 can be rotated around the waste liquid negative pressure recovery pipe 26, so that after cleaning and disinfection, the cleaning waste water and disinfectant can be extracted through the elbow 23 and the waste liquid negative pressure recovery pipe 26, and the residual liquid remaining at the bottom of the fixed cap 15 can be cleaned.

[0039] In this embodiment, the lower end of the fixed sheath 5 is provided with a fixed cap 15, which is detachably connected to the lower end of the fixed sheath 5. A silicone leak-proof sheet 16 is provided at the center of the lower end of the fixed cap 15. The silicone leak-proof sheet 16 has an opening for the lens 7 of the thoracoscope 3 to pass through. When the thoracoscope 3 is pressed down, the end of the lens 7 pushes open the opening of the silicone leak-proof sheet 16, and the opening opens. The edge of the opening fits against the surface of the lens 7 of the thoracoscope 3, scraping off excess disinfectant or water stains. When the thoracoscope 3 is retracted, the opening closes. A sealing ring 17 is provided at the connection between the fixed cap 15 and the fixed sheath 5. The shape of the opening of the silicone leak-proof sheet 16 can be designed to fit the shape of the lens 7, ensuring that the edge fits against the outer edge of the lens 7 to prevent leakage. The fixed cap 15 and the fixed sheath 5 can be threaded or snap-fitted. Since the silicone leak-proof sheet 16 is made of elastic silicone, it has a limited lifespan and is difficult to sterilize. Repeated use can easily lead to cross infection. Conventional thoracoscopes and automatic cleaning sheaths are typically made of stainless steel, which is more convenient to clean and sterilize. Therefore, a removable fixing cap 15 is used, making it a disposable item that is discarded and replaced after each surgery, thus avoiding cross infection and leakage caused by aging of the silicone leak-proof sheet 16.

[0040] In this embodiment, a snap-fit ​​device 18 is provided between the upper end of the cleaning component base 4 and the fixed sheath 5 . After the snap-fit ​​device 18 is snapped, the cleaning component base 4 and the fixed sheath 5 cannot rotate relative to each other.

[0041] In this embodiment, the outer edge diameter of the incision outer fixed end 12 is larger than the outer diameter of the incision insertion end 13, the outer edge of the lens insertion end 9 is provided with a snap-fit ​​protrusion 11, and the upper end of the lens insertion end 9 is provided with an inwardly inclined guide section 10.

[0042] In this embodiment, the waste liquid negative pressure recovery pipe 26 is externally connected to a negative pressure suction device to negatively suction out the wastewater or disinfectant generated during the cleaning and disinfection process; the upper end of the disinfectant injection pipe 19 is externally connected to a disinfectant supply device. Generally speaking, the disinfectant supply device will supply diluted iodine tincture for disinfection, or other liquids used to clean and disinfect the thoracoscope during surgery, in order to allow the lens surface to be disinfected again after cleaning, so that its surface is drier and the lens is clearer; the upper end of the cleaning liquid injection pipe 20 is externally connected to a cleaning liquid supply device. The cleaning liquid can be water, physiological saline, or other common medical cleaning liquids used to clean blood stains on the lens surface, in order to promptly rinse away blood stains attached to the lens surface during surgery to avoid affecting the progress of the surgery. The negative pressure suction device, disinfectant supply device, and cleaning liquid supply device are all external existing equipment and will not be described in detail here.

[0043] In this embodiment, the automatic cleaning device for thoracoscope includes the following steps when working:

[0046] C. Insert the cleaning assembly base 4 into place from the lens insertion end 9 of the fixed sheath 5, and fasten the fastening device 18 with the fastening protrusion 11 on the lens insertion end 9 of the fixed sheath 5 to ensure that the two do not move relative to each other; the waste liquid negative pressure recovery pipe 26 is externally connected to a negative pressure suction device, the upper end of the disinfectant injection pipe 19 is externally connected to a disinfectant supply device, and the upper end of the cleaning liquid injection pipe 20 is externally connected to a cleaning liquid supply device; connect the cold light source to the cold light source interface of the thoracoscope 3, and connect the thoracoscope 3 handle to the handle connection end 2 of the thoracoscope 3;

[0047] D. Hold the handle of the thoracoscope 3 and insert the lens 7 of the thoracoscope 3 into the working channel of the cleaning assembly base 4 until the lens 7 passes through the silicone leak-proof sheet 16 and reaches the chest cavity. During insertion, keep the cold light source interface of the thoracoscope 3 facing away from the operating surgeon, and keep the lens 7 of the thoracoscope 3 facing the organ to be operated on in the patient's chest cavity.

[0048] E. When the lens (7) is contaminated and blurred during the operation, the thoracoscope 3 is retracted until the lens 7 of the thoracoscope 3 is retracted to the top of the silicone leak-proof sheet 16 and the opening of the silicone leak-proof sheet 16 is closed;

[0049] F. Turn on the cleaning liquid supply device, and the cleaning liquid is sprayed from the cleaning nozzle 22 onto the slope 25 of the lens 7 to clean the lens 7;

[0050] G. After cleaning is completed, the cleaning liquid supply device is turned off and the negative pressure suction device is turned on to suck the flushed liquid out from the elbow 23 into the waste liquid negative pressure recovery pipe 26.

The liquid flowing down after the thoracoscope cleaning is sucked out completely;

[0051] H. After the suction is complete, turn off the negative pressure suction device, turn on the disinfectant supply device, and drain the disinfectant to the lower end of the thoracoscope 3 to flush and disinfect the entire lower end of the thoracoscope 3;

[0052] I. After disinfection is completed, the disinfectant supply device is turned off, and the negative pressure suction device is turned on to suck the flushed liquid out from the elbow 23 into the waste liquid negative pressure recovery pipe 26. At the same time, the depth of the waste liquid negative pressure recovery pipe 26 is adjusted up and down, and the position of the elbow 23 is rotated to perform adaptive position adjustment. The liquid flowing down from the thoracoscope after disinfection is sucked out. After the liquid is sucked out, the negative pressure suction device is turned off;

[0053] J. When the lens 7 is fogged, the anti-fog heating device 24 is turned on to perform the defogging operation; when the lens 7 is not fogged, this step is omitted;

[0054] K. Press down the thoracoscope 3. When the thoracoscope 3 is pressed down, the end of the lens 7 pushes open the opening of the silicone leak-proof sheet 16. The opening is opened, and the edge of the opening fits against the surface of the lens 7 of the thoracoscope 3 to scrape off excess disinfectant water stains.

[0055] L. Repeat steps DK.

[0056] In this embodiment, the device is not limited to the thoracoscope 3, and the corresponding thoracoscope 3 can also be replaced with corresponding laparoscopic equipment such as a laparoscope, an arthroscope, etc. The principle is the same and the adaptability is wide.
