技术领域Technical Field
本发明属于医疗设备技术领域，具体地说是一种用于腹腔镜的防油污镜鞘。The invention belongs to the technical field of medical equipment, in particular to an oil-proof scope sheath for a laparoscope.
背景技术Background Art
腹腔镜手术是一种常见且广泛应用的微创手术方式。与传统开腹手术相比，腹腔镜手术通过微小切口引入镜头和手术器械，具有创伤小、恢复快、疼痛少等优势。然而，腹腔镜手术的成功依赖于手术过程中清晰的视野，这对外科医生来说至关重要。在腹腔镜手术中，清晰的手术视野是确保手术安全和效果的关键因素。任何妨碍视野的因素都可能增加手术的复杂性和风险。Laparoscopic surgery is a common and widely used minimally invasive surgical method. Compared with traditional open surgery, laparoscopic surgery introduces cameras and surgical instruments through tiny incisions, which has the advantages of less trauma, faster recovery, and less pain. However, the success of laparoscopic surgery depends on a clear field of vision during the operation, which is crucial for surgeons. In laparoscopic surgery, a clear surgical field of view is a key factor in ensuring the safety and effectiveness of the operation. Any factors that hinder the field of vision may increase the complexity and risk of the operation.
现有技术问题是腹腔镜镜头容易受到污染。特别是在使用超声刀进行手术时，超声刀的震动会产生雾状油滴，这些油滴飞溅到镜头上后会导致视野模糊不清。当镜头被污染后，外科医生需要停止手术并将镜头取出腹腔进行清洁。这不仅打断了手术流程，还可能影响手术的关键时刻，例如止血或精确切除组织的最佳时机。通常情况下，腹腔镜手术中需反复清洁镜头，以确保手术过程中的视野清晰。而在较为肥胖的患者中，由于腹腔内脂肪含量较多，这种清洁操作可能需要更频繁地进行。反复清洁镜头意味着手术时间的延长，增加了患者暴露在麻醉和手术环境中的时间，从而增加了手术的总体风险。The problem with the prior art is that the laparoscope lens is easily contaminated. Especially when using an ultrasonic scalpel for surgery, the vibration of the ultrasonic scalpel will produce misty oil droplets, which will splash onto the lens and cause blurred vision. When the lens is contaminated, the surgeon needs to stop the operation and remove the lens from the abdominal cavity for cleaning. This not only interrupts the surgical process, but may also affect critical moments of the operation, such as the best time to stop bleeding or precisely remove tissue. Normally, the lens needs to be cleaned repeatedly during laparoscopic surgery to ensure a clear field of vision during the operation. In more obese patients, this cleaning operation may need to be performed more frequently due to the higher fat content in the abdominal cavity. Repeated cleaning of the lens means a longer operation time, which increases the patient's exposure to anesthesia and the surgical environment, thereby increasing the overall risk of the operation.
发明内容Summary of the invention
为了解决上述技术问题，本发明提供一种用于腹腔镜的防油污镜鞘，减少镜头污染的频率和清洁镜头所需的时间，以及提高手术效率、减少风险并改善手术效果，以解决现有技术中腹腔镜镜头容易受到污染，故需要反复清洁腹腔镜镜头，反复清洁镜头意味着手术时间的延长，增加了患者暴露在麻醉和手术环境中的时间，从而增加了手术的总体风险问题。In order to solve the above technical problems, the present invention provides an oil-proof scope sheath for a laparoscope, which reduces the frequency of lens contamination and the time required for cleaning the lens, and improves surgical efficiency, reduces risks and improves surgical results, so as to solve the problem that the laparoscope lens in the prior art is easily contaminated and needs to be repeatedly cleaned.

具体实施方式DETAILED DESCRIPTION
下面结合附图和实施例对本发明的实施方式作进一步详细描述。以下实施例用于说明本发明，但不能用来限制本发明的范围。The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
如图1-3所示，本发明提供一种用于腹腔镜的防油污镜鞘，包括镜头固定装置和镜头保护装置，所述镜头固定装置与镜头保护装置配合装配在一起，所述镜头保护装置包括镜鞘1和保护鞘2，镜头保护装置上镜鞘1表面凸起外部结构与腹腔镜镜头尾部预留的凹槽相契合，所述保护鞘2的内径尺寸与腹腔镜镜头尺寸相匹配，所述镜鞘(1)的头部安装有保护鞘(2)，所述保护鞘(2)为双层空心筒状结构，内含多条气体导轨，所述镜鞘(1)近端安装有安装有鲁尔接头(3)，且保护鞘2和鲁尔接头3之间设置有气体控制阀4，所述保护鞘2的头部安装有末端镜片5，用密封镜头保护套筒，并提供清晰、抗眩光、无失真的光学通道，所述镜鞘1和腹腔镜连接处尾端包裹有线缆保护装置6。As shown in Figures 1-3, the present invention provides an oil-proof scope sheath for a laparoscope, comprising a lens fixing device and a lens protection device, wherein the lens fixing device and the lens protection device are assembled together, wherein the lens protection device comprises a scope sheath 1 and a protection sheath 2, wherein the raised external structure on the surface of the scope sheath 1 on the lens protection device matches the groove reserved at the rear end of the laparoscope lens, wherein the inner diameter of the protection sheath 2 matches the size of the laparoscope lens, wherein the head of the scope sheath (1) is provided with a protection sheath (2),wherein the protection sheath (2)is a double-layer hollow cylindrical structure and contains a plurality of gas guide rails, whereinthe proximal end of the scope sheath (1) is providedwith a Luer connector (3), and a gas control valve 4 is provided between the protection sheath 2 and the Luer connector 3, wherein the head of the protection sheath 2 is provided with an end lens 5, a sealed lens protection sleeve is used, and a clear, anti-glare, distortion-free optical channel is provided, and a cable protection device 6 is wrapped around the rear end of the connection between the scope sheath 1 and the laparoscope.
保护鞘2的内外径之间设置有多条独立的导气轨道，导气出口的聚焦式设计可以使气流在镜头表面行程倒锥状气体保护墙，能够更加有效防污。A plurality of independent air guide tracks are arranged between the inner and outer diameters of the protective sheath 2. The focusing design of the air guide outlet can enable the airflow to form an inverted cone-shaped gas protection wall on the lens surface, which can more effectively prevent dirt.
末端镜片5上涂覆有疏油层和抗反射涂层，疏油层的存在便于水雾和油污迅速脱离镜片表面，大大加快了镜片清洁效率，将腹腔镜防油污功能和除水雾功能整合，能够应对手术中绝大多数污染腹腔镜的场景。The end lens 5 is coated with an oleophobic layer and an anti-reflective coating. The presence of the oleophobic layer facilitates the rapid detachment of water mist and oil from the lens surface, greatly accelerating the lens cleaning efficiency. The laparoscope's anti-oil and water mist removal functions are integrated to cope with most scenarios of laparoscope contamination during surgery.
鲁尔接头3和气体控制阀4为PC材质，可避免腹腔镜高温消毒，为除雾提供气体导出通路。The Luer connector 3 and the gas control valve 4 are made of PC material, which can avoid high-temperature disinfection of the laparoscope and provide a gas outlet path for defog.
线缆保护装置6聚乙烯材质，选用聚乙烯材质能够具有良好的透明性、柔软性和耐磨性，从而达到隔离线缆的目的，避免线缆污染手术台。The cable protection device 6 is made of polyethylene material. The polyethylene material can have good transparency, softness and wear resistance, so as to achieve the purpose of isolating the cables and prevent the cables from contaminating the operating table.
工作原理：首先将腹腔镜置于保护鞘2中，并将腹腔镜镜头尾部与镜鞘1旋转固定装配在一起，并用镜鞘1尾部的线缆保护装置6包裹住腹腔镜上的线缆，将气腹管接在鲁尔接头3上，打开气体控制阀4，打开恒压气腹机，给予通气，最后打开其余任一腹腔镜穿刺器的气体阀门，实现保持腹内压恒定的同时，持续有气流导入，通过该导气出口的聚焦式设计可以使气流在镜头表面行程倒锥状气体保护墙，能够更加有效防污，同时有油污落入到镜头的表面上时，另外持续流动的气体会加速镜头水雾的挥发，从而解决由于腹内外温差导致的镜头表面起雾现象，本方案通过多方面实现腹腔镜防油污功能以及除水雾功能，能够应对手术中绝大多数污染腹腔镜的场景。Working principle: first, place the laparoscope in the protective sheath 2, and rotate and fix the tail of the laparoscope lens and the scope sheath 1 together, and wrap the cable on the laparoscope with the cable protection device 6 at the tail of the scope sheath 1, connect the pneumoperitoneum tube to the Luer connector 3, open the gas control valve 4, turn on the constant pressure pneumoperitoneum machine, and provide ventilation. Finally, open the gas valve of any other laparoscopic puncture device to achieve constant intra-abdominal pressure while continuously introducing airflow. The focusing design of the gas guide outlet can make the airflow form an inverted cone-shaped gas protection wall on the surface of the lens, which can more effectively prevent pollution. At the same time, when oil falls on the surface of the lens, the continuous flow of gas will accelerate the volatilization of water mist on the lens, thereby solving the fogging phenomenon on the lens surface caused by the temperature difference between the inside and outside of the abdomen. This solution realizes the laparoscope's anti-oil and de-fogging functions in many aspects, and can cope with most of the scenarios of contaminated laparoscopes during surgery.
