Description

Technical Field

[0001] The present invention relates to the technical field of laparoscopic instruments, and in particular to an anti-fogging device for laparoscopic gastrointestinal surgery. Background Art

[0002] Laparoscopic surgery has become a mainstream procedure in gastrointestinal surgery due to its advantages such as minimal trauma and rapid recovery. During surgery, the clarity of laparoscopic imaging directly determines the safety and efficiency of the operation. However, in actual application, the following clinical problems exist: due to the difference between the ambient temperature in the abdominal cavity and the temperature of the lens surface, especially after flushing with low-temperature disinfectant, water vapor easily condenses into fog on the lens surface, resulting in a blurred field of view. Traditional solutions include applying anti-fog agents before surgery or wiping frequently during surgery. However, the anti-fog coating easily loses its effectiveness after contact with blood or tissue fluid, requiring repeated application; the wiping operation requires withdrawing the lens, interrupting the surgical process and increasing the risk of complications.

[0003] There's also the issue of bodily fluid contamination. During intraoperative electrocoagulation for hemostasis or tissue separation, smoke, blood, or exudate can easily splash onto the lens surface, blurring the image. Existing technologies often rely on water injection systems, such as injecting saline through instrument channels. However, these systems have the following limitations: Fluid accumulation in the abdominal cavity requires additional suction, prolonging the procedure; frequent water injections can dilute clots and increase the risk of postoperative bleeding; and high-pressure irrigation can cause mechanical damage to delicate tissues, such as the intestinal wall.

[0004] Furthermore, some existing devices are designed for specific models or types of laparoscopes and are not widely applicable to a variety of laparoscope lenses of different specifications and brands, limiting their scope of use. Therefore, considering the aforementioned shortcomings of laparoscopic gastrointestinal surgery, those skilled in the art have proposed a solution to address this issue with an anti-fog device for laparoscopic gastrointestinal surgery.

[0030] In order to more clearly explain and illustrate the technical solution and implementation of the present invention, preferred specific embodiments for implementing the technical solution of the present invention are introduced below.

[0031] A gastrointestinal surgical laparoscopic anti-fogging device comprises: a laparoscopic endoscope 1, a lens connecting component 2, a lens negative pressure anti-fogging component 3 and a lens anti-fogging component 4.

[0032] The laparoendoscope 1 includes the following parts: the main body of the scope 11 is a cylindrical structure with an integrated optical imaging system; the insertion part 12 is fixed to the front end of the scope 11, made of flexible material, and can be bent to adapt to intra-abdominal operations; the control knob 13 is set on the right side of the scope 11, and the bending angle of the insertion part 12 is controlled by adjusting the knob; the eyepiece 14 is fixed to the rear end of the scope 11 for the operator to observe the intra-abdominal image, and the image transmission cable 15 is connected to the left side of the scope 11 to transmit the image signal to the external display device; the front end of the insertion part 12 is fixedly connected to the connection end 24 of the lens connection assembly 2 to ensure the continuity of optical transmission.

[0033] The lens connection assembly 2 includes: the front end of the internally threaded sleeve 21 is fixedly connected to the lens body 41 of the lens anti-fogging assembly 4, the inner cavity is provided with screw threads, the rear end of the connecting end 24 is fixedly connected to the insertion part 12, and the outer surface is provided with a thread adapted to the internally threaded sleeve 21; the transmission interface 22 is fixed to the rear end of the internally threaded sleeve 21 and inserted into the transmission plug 23 of the connecting end 24 to realize lossless transmission of optical signals; the threaded rotation connection method is used to facilitate quick disassembly of the lens.

[0034] The lens negative pressure anti-sticking component 3 includes: a micro-liquid pump 31 fixed to the outer surface of the lens body 11 through a clamp to provide negative pressure power; a liquid suction catheter 32 is connected to the suction port of the micro-liquid pump 31 through a pipe joint, and its front end extends to the front end of the lens 44 and is flush with its end face, and is used to suck the body fluid around the lens. The discharge pipeline is connected to the discharge port of the micro-liquid pump 31 to discharge the sucked body fluid to an external container; the liquid suction catheter 32 is locked on the surface of the insertion part 12 by multiple pipe clamps.

[0035] The lens anti-fogging assembly 4 includes: a lens 44 is fixed at the front end of a lens body 41, an optical lens is integrated inside, a silicone jacket 42 is covered on the outer ring of the lens body 41, and a plurality of grooves are provided on the inner side, an electric heating ring 43 is embedded in the groove of the silicone jacket 42, and the heating end face is in contact with the lens body 41, and uniform heating is used to prevent the lens from fogging, and a micro temperature sensor is embedded in the outer side of the silicone jacket 42 to monitor the abdominal cavity temperature in real time and feed back to the external controller to prevent overheating and damage to the tissue and keep the temperature of the lens 44 within the range consistent with the patient; wherein, the electric heating ring 43 is powered by low voltage and the heating power is adjusted by an external controller; wherein, a wiring groove is provided inside the silicone jacket 42, and the groove is filled with wires for powering the electric heating ring 43, and the outer surface of the insertion part 12 and the lens connecting assembly 2 also has grooves for wiring the power lines. It is also worth mentioning that the outer diameter of the lens anti-fogging component 4 is 1 cm, which is used to adapt to the 10mm puncture sheath, and the silicone jacket 42 on the lens anti-fogging component 4 has a high temperature resistance of 200℃-300℃, which prevents high temperature disinfection from damaging the lens anti-fogging component 4.

[0036] The workflow is described as follows:

[0037] Connect the lens anti-fogging assembly 4 to the laparoendoscope 1 through the internal threaded sleeve 21, start the electric heating ring 43 to preheat the lens, adjust the angle of the insertion part 12 by controlling the knob 13, and the electric heating ring 43 maintains the lens temperature higher than the intra-abdominal environment to avoid condensation of water vapor. The micro suction pump 31 continuously sucks the body fluid in front of the lens to prevent contamination. Remove the lens connecting assembly 2 and disinfect or replace the lens anti-fogging assembly 4.

[0038] Example 1: Optimizing the lens anti-fogging component.

[0039] Among them, the mirror body 41 is made of medical-grade stainless steel and the surface is covered with a nano-hydrophobic coating to further reduce the adhesion of body fluids. The electric heating ring 43 is replaced by a spiral electric heating wire, which is wrapped around the outer surface of the mirror body 41 and fixed by a silicone jacket 42. The spiral design makes the heating more uniform and avoids local overheating. A micro temperature sensor is embedded on the outside of the silicone jacket 42 and connected to an external controller to adjust the heating power in real time. The front end of the extraction catheter 32 is designed as a flexible catheter head with adjustable angle. It is driven by a micro motor. The suction direction can be adjusted during the operation to accurately remove the liquid on the side of the lens 44. A filter is added inside the drainage pipeline to separate the aspirated body fluids and gases to avoid clogging the pipeline. Among them, the inner side of the 10mm puncture sheath used in conjunction with the laparoendoscope 1 has a semi-cylindrical groove for the extraction catheter 32 to pass through. The groove is filled with a silicone pad to seal the gap between the extraction catheter 32 and the 10mm puncture sheath.

[0040] During use, before the operation, the lens anti-fogging component 5 is connected to the laparoendoscope 2 through the internal threaded sleeve 21, and the spiral heating wire is started to preheat to 40°C. During the operation, the temperature upper limit is set by the controller, and the temperature sensor feeds back data in real time to prevent overheating. When blood accumulates on the side of the lens 44, the operator controls the flexible catheter head of the liquid extraction catheter 32 to deflect 30° through the foot switch to directionally aspirate the liquid.

[0041] Example 2: Further optimize the anti-fog and anti-fog functions of the device.

[0042] A control chip is integrated inside the mirror body 11, connecting the electric heating ring 43, the micro-liquid extraction pump 31 and the micro-temperature sensor. A humidity sensor is added and embedded in the front end of the silicone jacket 42 to detect humidity changes around the lens 44. Moreover, the internal threaded sleeve 21 is replaced with a magnetic quick-release structure, which improves the installation and disassembly speed by magnetically docking the transmission interface 22 and the transmission plug 23. After the system is started, the humidity sensor detects the humidity on the surface of the lens 44, automatically increases the power of the electric heating ring 43 to the highest level, and eliminates fog within 3 seconds. When the suction efficiency of the liquid extraction tube 32 decreases, such as when there is a large resistance in the pipeline, the control chip automatically increases the speed of the micro-liquid extraction pump 31 to maintain a constant negative pressure.
