Description

Technical Field

[0001] The invention relates to the technical field of thoracoscope lens cleaning, and in particular to a thoracoscope lens cleaning device. Background Art

[0002] Solutions to the blur of single-hole VATS lenses include wiping with iodine gauze blocks or soaking and heating with sterile saline stored in a thermos cup. However, there are many problems with the above methods. On the one hand, wiping the lens with iodine gauze blocks can prevent fogging and clean the lens, but it cannot achieve the same effect every time. The reason is that the moisture content of the iodine gauze decreases with the increase in the frequency of use. Secondly, each wipe cannot effectively form a coating on the lens, resulting in poor lens cleaning effect or excessive iodine causing the lens to display yellow. On the other hand, when using a thermos cup for heating and cleaning, it can also prevent fogging and clean the lens, but in clinical applications, the water temperature of the insulation cannot be guaranteed. There are cases where overheating has caused the lens to break, and overcooling has no effect. In addition, there are cases where the lens collides with the bottom of the thermos cup and breaks when using a thermos cup. There are also risks such as hot water in the cup contaminating the countertop and scalding.

[0003] In response to the current situation, some related cleaning device technologies have been published, but the existing technologies have certain defects in clinical applications: on the one hand, simply flushing the laparoscope lens lacks a carrier for intraoperative use, and the hand-held gauze used in the application of iodine-containing medical gauze cannot guarantee the flat folding surface mentioned in the patent, which is insufficient to achieve uniform contact between the lens and the gauze surface, and the iodine-containing gauze forms a uniformly thick moist film on the lens to play an anti-fogging role. In addition, the existing technology lacks a fundamental solution to the cause of lens blur in clinical single-port thoracoscopic surgery.

[0004] Chinese Patent Publication No.: CN118557128A discloses a thoracoscopic and laparoscopic lens cleaning device, comprising: a cleaning barrel, a cleaning assembly is provided in the cleaning barrel, the opening of the cleaning barrel is upward; a drying barrel, the drying barrel is located on the outside of the cleaning barrel, the opening of the drying barrel is downward, and the drying barrel is connected to the drying assembly; a partition, the partition is used to seal the opening of the drying barrel and the opening of the cleaning barrel. The beneficial effects of the invention: through the setting of the drying barrel and the cleaning barrel, when it is necessary to clean the thoracoscopic and laparoscopic lens, only the drying tube needs to be moved to complete the two functions of cleaning and heating, so that the lens can be cleaned and prevented from fogging, ensuring that the lens is clean and clear, reducing the work pressure of the doctor holding the lens, ensuring the continuity of the surgeon's surgical ideas and operations, and improving the work efficiency of the surgical team.

[0005] It can be seen that the thoracoscopic and laparoscopic lens cleaning device has the following problems: although the technology uses an electric cleaning rod and a sealed drying barrel for drying and heating, which is achieved through a base, a motor and a control system, in clinical applications, lens cleaning emphasizes speed and effectiveness, especially when intraoperative bleeding causes the lens field of view to disappear, the clinical application of this technology has certain limitations. Summary of the invention

[0006] To this end, the present invention provides a thoracoscopic lens cleaning device to overcome the problem of low cleaning efficiency of the thoracoscopic lens caused by slow lens cleaning speed in the prior art.

[0007] To achieve the above object, the present invention provides a thoracoscope lens cleaning device, comprising:

[0008] A thoracoscope, which includes a lens for acquiring images of the surgical site in real time;

[0009] A support tube, used for supporting the thoracoscope to enter the surgical incision;

[0010] A cleaning mechanism, comprising a decontamination cover, a cleaning tube eccentrically arranged outside the support tube, and a cleaning base arranged at the bottom of the cleaning tube, for cleaning the lens;

[0011] A negative pressure suction mechanism, comprising a smoking pipe, a plurality of smoking holes arranged on the end of the smoking pipe wall away from the decontamination cover, and a siphon port arranged on the cleaning pipe wall;

[0012] A data acquisition module, which is connected to the thoracoscope and includes an optical signal monitoring component for acquiring the incident light spectrum and the transmitted light spectrum of the lens in real time;

[0013] A control mechanism, which is respectively connected to the thoracoscope, the cleaning mechanism and the negative pressure suction mechanism, comprises:

[0014] a data analysis module, comprising an image analysis component and a spectrum analysis component, wherein the image analysis component is used to determine the resolution of the image based on the image to determine whether to start cleaning the lens and the eligibility of the cleaning effect of the lens, and the spectrum analysis component is used to determine the distribution mode and pollution index of the pollutants based on the comparison result of the incident light spectrum and the transmitted light spectrum;

[0015] An execution control module is responsive to the analysis result of the data analysis module to determine a cleaning mode based on the distribution mode, determine a pressing depth and a number of cleaning circles of the lens based on the contamination index, and correct a cleaning parameter of the lens based on an unqualified cleaning effect.

[0016] Furthermore, the data analysis module determines to issue a prompt to stop the operation and start cleaning the lens based on the comparison result that the resolution is less than the first preset resolution.

[0017] Furthermore, the data analysis module compares the transmitted light spectrum with the spectrum of the incident light, determines the change amplitude of each light wave with a changed wavelength to determine the maximum change amplitude and the minimum change amplitude, records the value of the maximum change amplitude as the pollution index, and subtracts the maximum change amplitude from the minimum change amplitude to obtain the amplitude difference, and determines that the distribution of pollutants is uniformly distributed based on the comparison result that the amplitude difference is less than or equal to the preset amplitude difference.

[0018] Furthermore, the data analysis module determines that the distribution of pollutants is non-uniform based on the comparison result that the amplitude difference is greater than the preset amplitude difference.

[0019] Furthermore, the execution control module determines that the cleaning mode of the lens is a first cleaning mode in which the cleaning base is kept horizontal under the condition that the pollutants are evenly distributed.

[0020] Furthermore, the execution control module determines that the cleaning mode of the lens is a second cleaning mode in which the cleaning base is tilted at a preset angle based on the condition of non-uniform distribution of pollutants.

[0021] Further, the execution control module determines, in the determined cleaning mode, to perform cleaning with a first pressing depth and a first number of cleaning cycles based on a comparison result that the pollution index is greater than a preset index;

[0022] Based on the comparison result that the pollution index is less than or equal to the preset index, it is determined to perform cleaning with a second pressing depth and a second number of cleaning cycles.

[0023] Furthermore, the data analysis module determines the resolution of the lens again after the first cleaning is completed, and determines that the cleaning effect of the lens is unqualified based on a comparison result that the resolution is less than a second preset resolution.

[0024] Further, the execution control module, under the condition that the cleaning effect is unqualified, obtains a resolution difference by subtracting the second preset resolution from the resolution, and determines to increase the pressing depth by a depth adjustment coefficient based on a comparison result that the resolution difference is less than or equal to the preset difference;

[0025] Based on the comparison result that the resolution difference is greater than the preset difference, it is determined to increase the number of cleaning circles by the circle adjustment coefficient.

[0026] Furthermore, the data acquisition module also includes a smoke sensor for real-time detection of smoke concentration, and the control mechanism determines to start the negative pressure suction mechanism when the smoke concentration is greater than or equal to a preset concentration.

[0027] Compared with the prior art, the invention has the following beneficial effects: the lens cleaning device provided by the invention is an automatic cleaning device and does not require manual operation; by providing a support tube, the thoracoscope is allowed to enter the surgical incision from the support tube, providing support for the thoracoscope, preventing the mirror rod from shaking in the air during the operation, causing the surgical field to shake and affecting the doctor's operation; the contaminants in the lens are initially cleaned by the gauze block and the cleaning sponge on the decontamination cover, so that the subsequent cleaning effect is better; by providing a cleaning tube, the mirror rod can be initially cleaned when the lens is deeply inserted into the cleaning base, and the mirror rod can also be cleaned by rotating when the lens is rotating for cleaning. The cleaning base is provided with a lens guide hole for guiding the lens to enter the cleaning base accurately, and the lens rotates on the gauze block at the bottom of the guide hole to clean the lens. At the same time, pressure can be applied to compress the cleaning sponge downward on the partition to squeeze the iodine tincture in the cleaning sponge into the gauze block to disinfect the lens. After the cleaning sponge is restored to its original state, the excess iodine tincture is absorbed by the cleaning sponge through the holes in the partition, thereby improving the utilization rate of the iodine tincture. After cleaning, the lens enters the surgical incision again through the support tube to continue the operation, thereby improving the cleaning efficiency of the thoracoscopic lens.

[0028] Furthermore, the present invention determines the resolution of the image presented by the lens. When the lens is contaminated, the resolution will decrease. Based on the resolution, the operation is stopped and the lens cleaning begins, thus avoiding the error of subjective judgment of the human eye, thereby improving the cleaning efficiency of the thoracoscopic lens.

[0029] Furthermore, the present invention determines whether the contaminants are evenly distributed on the lens or unevenly distributed by comparing the spectra of light emitted by the light source and the transmitted light. When evenly distributed, the contaminants cover the surface of the lens as a thin film or a uniform scattering layer, resulting in overall attenuation of the spectrum, that is, light waves of all wavelengths will be absorbed or scattered to a certain extent, but the relative intensity relationship between the wavelengths may remain unchanged or change slightly, making the image captured by the thoracoscopic lens blurred, but will not significantly change the overall shape of the spectrum; when the contaminants are unevenly distributed, larger scatterers or agglomerates will be formed, which will have a stronger scattering effect on the light waves. The positions of the distributed contaminants cause the light waves to be strongly scattered, while the light waves at other positions are relatively weakly affected, resulting in changes in the wavelength; different cleaning methods are selected for different distribution methods, and the contaminated positions are accurately cleaned, thereby improving the cleaning efficiency of the thoracoscopic lens.

[0030] Furthermore, the present invention selects a cleaning mode in which the cleaning base is horizontal for evenly distributed contaminants, ensuring that the lens is completely in contact with the yarn block, and performs cleaning with a certain pressing depth and number of cleaning circles. For unevenly distributed contaminants, the present invention selects a cleaning mode in which the cleaning base is tilted. Under the same pressing force, the cleaning base is tilted so that the extrusion force on the lens is unbalanced, increasing the friction of the contact part, and the entire lens can be covered by rotation, thereby improving the cleaning efficiency of the thoracoscope lens.

[0031] Furthermore, the present invention selects to increase the pressing depth and the number of cleaning circles to improve the cleaning effect in the cleaning process with unsatisfactory cleaning effect. The greater the pressing depth, the greater the friction between the lens and the yarn block, and the better the effect of cleaning the contaminants; the more cleaning circles, the longer the contact time between the lens and the yarn block, and the better the effect of cleaning the contaminants, thereby further improving the cleaning efficiency of the thoracoscope lens.

[0032] Furthermore, the present invention is also provided with a negative pressure suction mechanism, which is turned on to extract the smoke when smoke is detected. The presence of smoke will also cause the resolution of the lens to decrease. By sucking away the smoke, the cause of the decrease in lens resolution is removed, thereby further improving the cleaning efficiency of the thoracoscopic lens. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] Specifically, the value range of the preset difference is set to [640×360, 2176×1080], and 1536×720 is preferably used in the embodiment of the present invention; the value range of the depth adjustment coefficient is set to [1.05, 1.2] and 1.13 is preferably used in the embodiment of the present invention.

[0086] Specifically, the value range of the number of turns adjustment coefficient is set to [1.2, 1.5], and 1.3 is preferred in the embodiment of the present invention.
