Description

Technical Field

[0001] The invention relates to the field of medical technology, in particular to a laparoscope with temperature adjustment and anti-lens blurring function. Background Art

[0002] Laparoscope is a medical device with a miniature camera. It consists of a mirror body, a light source, a conduction system and an imaging system. By making several small incisions in the abdomen and inserting the laparoscope into the abdominal cavity, the camera can take pictures of the situation in the abdominal cavity and transmit the images to the display screen, so that the doctor can visually observe the shape, size, position and presence of lesions of the organs in the abdominal cavity. Laparoscopes are often used to diagnose and treat a variety of abdominal diseases, such as cholecystitis, appendicitis, ovarian cysts, uterine fibroids, etc. Compared with traditional open surgery, laparoscopic surgery has the advantages of less trauma, faster recovery, less pain and fewer complications.

[0003] A clear field of vision is extremely important for precise surgical operations. When the temperature inside the abdominal cavity is significantly different from the external ambient temperature, the lens will easily become blurred due to the cold and fog after entering the abdominal cavity; once the lens is blurred, the doctor will not be able to accurately judge the details of the tissue structure and the lesion site, which may lead to surgical errors, such as miscutting normal tissues and missing lesions, thereby increasing the risk of surgery and the probability of complications.

[0004] During surgery, carbon dioxide gas is usually heated to near body temperature before being injected into the abdominal cavity to keep the abdominal temperature stable, thereby preventing the laparoscope from fogging up due to temperature changes and causing blurry lenses. However, if too much carbon dioxide is absorbed inside the abdominal cavity, the concentration of carbon dioxide in the blood will increase, causing hypercapnia, respiratory acidosis, arrhythmia and other symptoms. Moreover, for patients with poor cardiopulmonary function, the increase in intra-abdominal pressure may increase the burden on the heart and lungs, leading to dyspnea, heart failure and other conditions. It is not convenient to stabilize the lens clarity by controlling the temperature around the laparoscope lens.

[0005] In view of this, the present invention provides a laparoscope with temperature adjustment to prevent lens blur. Summary of the invention

At the same time, it can wash away the stains on the surface of the lens piece and adjust the refraction angle between the camera and the lens piece.

[0010] As a further improvement of the present technical solution, the temperature control component includes a water inlet pipe and a water outlet pipe, one end of the water inlet pipe and the water outlet pipe are fixedly connected to a one-way valve, the two one-way valves are fixedly connected to the outer wall of the cavity tube, the other end of the water inlet pipe is fixedly connected to a hot water pump, and the other end of the water outlet pipe is fixedly connected to a water pump.

[0011] As a further improvement of the present technical solution, the one-way valve includes a valve housing, which is fixedly connected to the outer wall of the cavity tube, and a pressure plate is movably connected inside the valve housing, a pressure rod is fixedly connected to the end of the pressure plate, and two clamps are fixedly connected to the other end of the pressure rod, and a plug is movably connected between the two clamps, and the plug is movably connected between the outer wall of the pressure rod and the inside of the conical groove of the valve housing, and an elastic member is fixedly connected between the end of the conical groove of the valve housing and the pressure plate.

[0012] As a further improvement of the present technical solution, the rotating assembly includes a plurality of rotating rods, two of which are symmetrically fixedly connected to the outer wall of the lens piece, the rotating rod is movably connected inside the cavity near the bottom, and the other rotating rod is movably connected to the outer wall of the cavity near the middle, and the end of the rotating rod passing through the cavity is fixedly connected to a roller, and the rotating rod and one of the outer walls of the rotating rod of the lens piece are fixedly connected to a belt pulley, and the two belt pulleys 241 are connected by a belt 242 to form a transmission mechanism.

[0013] As a further improvement of the technical solution, a piston is provided between the outer wall of the lens piece and the inner wall of the cavity tube, the piston is fixedly connected to the inner wall of the cavity tube, the piston is movably connected to the lens piece, and the piston is made of rubber.

[0014] As a further improvement of the technical solution, one side of the lens piece is a concave mirror, and the other side of the lens piece is a convex mirror.

[0015] As a further improvement of the present technical solution, the height adjustment assembly includes a bolt, which is fixedly connected to the outer wall of the camera, the outer wall of the cavity through which the camera passes is fixedly connected to a turntable, and the end of the cavity through which the camera passes is fixedly connected to a cable.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the laparoscope with temperature adjustment to prevent lens blurring, by starting the hot water pump, the temperature control component is prompted to transport the hot fluid to the inside of the cavity; at this time, the heat carried by the hot fluid (such as warm water that has been heated) will be quickly transferred to the lens and its surrounding area, thereby heating the lens and raising its temperature, effectively preventing fogging and blurring caused by low temperature; and when the temperature reaches or exceeds the preset value, the water pump will start to pump out the water inside the cavity to prevent the lens from overheating due to overheating, ensuring that the temperature of the lens is always maintained within an appropriate range.

[0018] 2. In the laparoscope with temperature adjustment to prevent lens blur, when the fluid is transported into the cavity, the fluid will flow through the surface of the lens, thereby washing away the stains on the surface of the lens; during the operation, if tissue fluid, blood, etc. in the abdominal cavity splashes onto the lens, the lens can be turned over by rotating the component so that the stains on the lens can be washed away when the fluid passes through, keeping the lens clear.

[0019] 3. In the laparoscope with temperature adjustment to prevent lens blur, the height of the camera is adjusted with the help of a height adjustment component; since different surgical sites and operations require different viewing angles and distances, adjusting the height of the camera can provide the most suitable observation angle; moreover, properly adjusting the camera height can avoid reflections and shadows caused by surgical instruments or tissues, thereby improving lighting effects and image quality.

[0020] 4. In the laparoscope with temperature adjustment to prevent lens blur, when there is fluid inside the cavity, the light emitted by the light ring needs to pass through the fluid before it can be projected onto the lens. Since the refractive index of water is different from that of air, when light enters water from air, the propagation speed of light slows down, causing the propagation direction of light to change and produce refraction. This refraction phenomenon is conducive to a more even distribution of light in the abdominal cavity, reducing shadows and dark areas, and providing a clearer and more comprehensive field of view for surgical operations. In addition, the changes in light and shadow formed by reflection and refraction can make organs and tissues more three-dimensional, which helps to judge their spatial position and mutual relationship.

[0038] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] See also Figure 1-Figure 9As shown, the purpose of this embodiment is to provide a laparoscope with temperature adjustment and anti-lens blur, including a support 1, a support rod 11 is fixedly connected to the top of the support 1, a cavity 2 is movably connected inside the support rod 11, a gun handle 21 is fixedly connected to the outer wall of the cavity 2, a camera 25 is movably connected inside the cavity 2, and a light ring 250 is fixedly connected to the outer ring at the end of the camera 25;

[0041] A lens piece 23 is movably connected to the inner part of the cavity tube 2 near the top, and a rotating assembly 24 is fixedly connected to both ends of the lens piece 23. The rotating assembly 24 is movably connected to the inner part of the outer wall of the cavity tube 2. A temperature control assembly 22 is fixedly connected to the inner part of the cavity tube 2 near the top, and a height adjustment assembly 26 is fixedly connected to the outer wall of the camera 25.

[0042] The rotating assembly 24 is used to realize the flipping and switching operation of the lens piece 23, the height adjustment assembly 26 is used to adjust the irradiation height of the camera 25 and the light ring 250, and the temperature control assembly 22 is used to adjust the temperature environment around the lens piece 23, and can also wash away the stains on the surface of the lens piece 23 and adjust the refraction angle between the camera 25 and the lens piece 23;

[0043] The improvement of this embodiment is that: by starting the hot water pump, the temperature control component 22 will transport the hot fluid (such as warm water after heating treatment) into the cavity tube 2; the heat carried by the hot fluid will be quickly transferred to the lens piece 23 and its surrounding area, so as to heat the lens piece 23 and increase its temperature to prevent fogging and blurring caused by too low temperature; when the temperature reaches or exceeds the preset value, the water pump will start to output the water in the cavity tube 2 to avoid excessive heating of the lens piece 23 and excessive temperature, so as to ensure that its temperature is always within an appropriate range;

[0044] When the fluid is delivered to the cavity 2, the fluid will flow through the surface of the lens piece 23 to wash away the stains on the surface; if the tissue fluid or blood in the abdominal cavity splashes onto the lens piece 23 during surgery, the lens piece 23 can be turned over by the rotating component 24 to facilitate washing away the stains when the fluid passes through, thereby keeping the lens piece 23 clear;

[0045] The height of the camera 25 is adjusted by using the height adjustment component 26. In view of the fact that different surgical sites and operations may require different viewing angles and distances, this can provide the most suitable observation angle. At the same time, appropriately adjusting the height of the camera 25 can avoid reflections and shadows caused by surgical instruments or tissues, thereby improving the lighting effect and image quality.

[0046] When there is fluid in the cavity 2, the light emitted by the light ring 250 needs to pass through the fluid before it can be projected on the lens 23; because the refractive index of water is different from that of air, the propagation speed of light slows down when it enters water from air, resulting in a change in propagation direction and refraction; this phenomenon can make the light more evenly distributed in the abdominal cavity, reduce shadows and dark places, and provide a clearer and more comprehensive field of view for surgical operations; moreover, the light and shadow changes caused by reflection and refraction can make organs and tissues more three-dimensional, which is helpful to judge their spatial positions and relationships;

[0047] First, the specific structure of the temperature control component 22 is disclosed. The temperature control component 22 includes an inlet pipe 220 and an outlet pipe 221. One end of the inlet pipe 220 and the outlet pipe 221 are fixedly connected with a one-way valve 222. The two one-way valves 222 are fixedly connected to the outer wall of the cavity tube 2. The other end of the inlet pipe 220 is fixedly connected with a hot water pump, and the other end of the outlet pipe 221 is fixedly connected with a water pump. When the temperature around the lens piece 23 is low, the hot water pump is used to allow the fluid to enter the cavity tube 2 through the inlet pipe 220 and the one-way valve 222, and then the fluid with a higher temperature flows along the cavity tube 2 to the lens piece 23, and the heat carried by the fluid is quickly transferred to the lens piece 23. When the lens piece 23 is heated to a certain degree, the water pump is operated to output the fluid inside the cavity tube 2 from the outlet pipe 221 through another one-way valve 222, so that the fluid inside the cavity tube 2 is discharged to ensure that its temperature is always within a suitable range.

[0048] The working principle of the hot water pump is known to those skilled in the art. The hot water pump is a device that can obtain low-temperature heat energy from the environment and convert it into high-temperature heat energy. Its working principle is based on a thermal cycle system. It is mainly composed of a compressor, a heat exchanger, an axial flow fan, an insulated water tank, a water pump, a liquid storage tank, a filter, an electronic expansion valve, and an electronic automatic controller. After the power is turned on, the axial flow fan starts to operate, and the outdoor air is heat exchanged through the evaporator. The air with a lowered temperature is discharged from the system by the fan. At the same time, the working fluid inside the evaporator absorbs heat and vaporizes and is sucked into the compressor. The compressor compresses this low-pressure working fluid gas into a high-temperature, high-pressure gas and sends it to the condenser. The water forced to circulate by the water pump also passes through the condenser, is heated by the working fluid, and is sent to the user for use. The working fluid is cooled into a liquid, which flows into the evaporator again after being throttled and cooled by the expansion valve. The cycle is repeated in this way, and the heat energy in the air is continuously "pumped" into the water, so that the water temperature in the insulated water tank gradually increases.

[0049] As is known to those skilled in the art, the working principle of the water pump is to use the movement of the piston to exhaust air, thereby creating a pressure difference between the inside and outside of the cylinder, so that water rises and is pumped out under the action of the air pressure. When the plug is pressed down, the water inlet valve is closed and the exhaust valve is opened; when the plug is lifted up, the exhaust valve is closed and the water inlet valve is opened. Under the action of the external atmospheric pressure, water flows out from the water inlet pipe through the water inlet valve and out of the water outlet above. In this way, the plug reciprocates up and down in the cylinder, continuously pumping out water.

[0050] The one-way valve 222 includes a valve housing 2220, which is fixedly connected to the outer wall of the cavity tube 2, and a pressure plate 2221 is movably connected inside the valve housing 2220. A pressure rod 2222 is fixedly connected to the end of the pressure plate 2221, and two clamping plates 2224 are fixedly connected to the other end of the pressure rod 2222. An embolism 2225 is movably connected between the two clamping plates 2224. The embolism 2225 is movably connected between the outer wall of the pressure rod 2222 and the inside of the conical groove of the valve housing 2220. The end of the conical groove of the valve housing 2220 is fixedly connected to the pressure rod 2222. An elastic member 2223 is fixedly connected between the valve housing 2220 and the pressure plate 2221. When the fluid passes through the valve housing 2220, it must first pass through the pressure plate 2221 and apply pressure to the pressure plate 2221, so that the pressure plate 2221 drives the pressure rod 2222 to apply pressure to the two clamping plates 2224, and at the same time presses the elastic member 2223 to contract, causing the embolism 2225 to move out of the conical groove part of the valve housing 2220, so that the fluid can pass through the conical groove of the valve housing 2220 to the outside, thereby allowing the fluid to pass smoothly.

[0051] Secondly, the specific structure of the rotating assembly 24 is disclosed. The rotating assembly 24 includes a plurality of rotating rods 240, two of which are symmetrically fixedly connected to the outer wall of the lens piece 23, the rotating rod 240 is movably connected to the inner part of the cavity tube 2 near the bottom, and the other rotating rod 240 is movably connected to the outer wall of the cavity tube 2 near the middle. The end of the rotating rod 240 passing through the cavity tube 2 is fixedly connected to a roller 243, and the rotating rod 240 and the outer wall of one of the rotating rods 240 of the lens piece 23 are both fixedly connected to a belt pulley 241, and the two belt pulleys 241 are connected by a belt 242 to form a transmission mechanism; by manually twisting the roller 243, the rotating rod 240 at its end is driven to rotate. The rotating rod 240 can drive the belt pulley 241 to rotate, and the belt pulley 241 drives the belt 242 to operate, thereby causing the other belt pulley 241 to rotate, driving the rotating rod 240 located on the lens piece 23 to rotate, applying a flipping pressure to the lens piece 23, and realizing the adjustment of the perspective state of the front and back sides of the lens piece 23;

[0052] During the operation, if the tissue fluid or blood in the abdominal cavity splashes onto the lens piece 23, the lens piece 23 can be turned over, the stained side can be turned over to the inside of the cavity 2, and then the fluid can be transported into the cavity 2 to wash the surface of the lens piece 23 to maintain the clarity of the lens piece 23;

[0053] Among them, one side of the lens piece 23 is a concave mirror, and the other side of the lens piece 23 is a convex mirror; a piston 20 is provided between the outer wall of the lens piece 23 and the inner wall of the cavity tube 2, and the piston 20 is fixedly connected to the inner wall of the cavity tube 2, and the piston 20 is movably connected to the lens piece 23. The piston 20 is made of rubber material. Due to the elastic properties of the rubber material itself, it can better fit with the surrounding components to form a good seal to prevent gas or liquid leakage, thereby ensuring the effective realization of functions such as temperature regulation and cleaning. The gap between the lens piece 23 and the cavity tube 2 is sealed by the piston 20, thereby improving the sealing degree between the lens piece 23 and the cavity tube 2, and preventing fluid from flowing out from the gap between the cavity tube 2 and the edge of the lens piece 23.

[0054] Secondly, the lens piece 23, through a unique concave-convex combination design, has the possibility of expanding the field of view in certain directions. In certain application scenarios, it can achieve a zoom-like effect and change the focus of light. This helps to reduce optical aberrations and improve image clarity and accuracy.

[0055] Finally, the specific structure of the height adjustment component 26 is disclosed. The height adjustment component 26 includes a bolt 260, which is fixedly connected to the outer wall of the camera 25. The camera 25 passes through the outer wall of the cavity 2 and is fixedly connected to a turntable 261. The end of the camera 25 passing through the cavity 2 is fixedly connected to a cable 262. The camera 25 is driven to rotate by rotating the turntable 261, and the bolt 260 rotates inside the cavity 2 through the rotation of the camera 25, so that the camera 25 moves up and down inside the cavity 2 with the rotation of the bolt 260, and the recording distance of the camera 25 and the irradiation distance of the light ring 250 are adjusted. Usually, the distance between the light ring 250 and the lens piece 23 is relatively close, which helps to concentrate the light and provide sufficient lighting intensity so that the tissue structure in the abdominal cavity can be clearly seen.

[0056] And when there is fluid in the cavity 2, the light emitted by the light ring 250 needs to pass through the fluid before it can be projected onto the lens 23; since the refractive index of water is different from that of air, the propagation speed of light slows down when it enters water from air, resulting in a change in the propagation direction and refraction; this phenomenon can make the light more evenly distributed in the abdominal cavity, reduce shadows and dark places, and provide a clearer and more comprehensive field of view for surgical operations; moreover, the changes in light and shadow caused by reflection and refraction can make organs and tissues more three-dimensional, which helps to judge their spatial position and mutual relationship.

[0057] In summary, the working principle of this solution is as follows:

[0058] When the temperature around the lens piece 23 is low, the hot water pump inputs the fluid into the cavity tube 2 through the water inlet pipe 220 and the one-way valve 222; so that the fluid with higher temperature flows along the cavity tube 2 to the lens piece 23, and quickly transfers the heat it carries to the lens piece 23; when the lens piece 23 is heated to a certain degree, the water pump works to discharge the fluid inside the cavity tube 2 from the water outlet pipe 221 through another one-way valve 222, thereby emptying the fluid inside the cavity tube 2 and ensuring that its temperature is always within a suitable range; in the one-way valve 222, when the fluid passes through the valve housing 2220, it is necessary to first apply pressure to the pressure plate 2221, so that the pressure plate 2221 drives the pressure rod 2222 to apply pressure to the two clamping plates 2224, and at the same time presses the elastic member 2223 to contract, so that the plug 2225 moves out of the tapered groove part of the valve housing 2220, so that the fluid can pass through the tapered groove of the valve housing 2220 to the outside, so that the fluid can pass smoothly;

[0059] The rotating roller 243 is manually twisted to drive the rotating rod 240 at its end to rotate, and the rotating rod 240 drives the belt pulley 241 to rotate, and the belt pulley 241 drives the belt 242 to rotate, so that the other belt pulley 241 rotates, and drives the rotating rod 240 on the lens piece 23 to rotate, and applies a flipping pressure to the lens piece 23, so as to adjust the perspective state of the front and back sides of the lens piece 23; this may expand the field of view in certain directions, achieve a zoom-like effect in specific applications, change the focusing degree of light, help reduce optical aberrations, and improve the clarity and accuracy of images;

[0060] Furthermore, if tissue fluid or blood in the abdominal cavity splashes onto the lens piece 23 during surgery, the lens piece 23 can be flipped over, with the stained side turned over to the inside of the lumen 2, and fluid can be transported into the lumen 2 to rinse the surface of the lens piece 23, thereby maintaining the clarity of the lens piece 23; the lens piece 23 is made of rubber material, and with its own elastic properties, it can better fit with surrounding components to form a good seal, prevent gas or liquid leakage, and ensure that functions such as temperature regulation and cleaning are effectively achieved; the gap between the lens piece 23 and the lumen 2 is sealed by the piston 20 to improve the sealing degree between the two and prevent the fluid from flowing out of the gap between the lumen 2 and the edge of the lens piece 23. Moreover, the special concave-convex combination of the lens piece 23 may expand the field of view in certain directions, achieve a zoom-like effect in specific applications, change the focus of light, help reduce optical aberrations, and improve the clarity and accuracy of the image;

[0061] The camera 25 is driven to rotate by rotating the turntable 261, and the rotation of the camera 25 causes the bolt 260 to rotate inside the cavity 2, so that the camera 25 moves up and down inside the cavity 2 as the bolt 260 rotates, and the recording distance of the camera 25 and the irradiation distance of the light ring 250 are adjusted; usually, the distance between the light ring 250 and the lens 23 is relatively close, which helps to concentrate the light and provide sufficient lighting intensity, so that the tissue structure in the abdominal cavity is clearly visible. And when there is fluid in the cavity 2, the light emitted by the light ring 250 needs to pass through the fluid before it can be projected on the lens 23; because the refractive index of water is different from that of air, the propagation speed of light from air into water slows down, resulting in a change in propagation direction and refraction. This phenomenon can make the light more evenly distributed in the abdominal cavity, reduce shadows and dark places, and provide a clearer and more comprehensive field of view for surgical operations; and the light and shadow changes caused by reflection and refraction can make organs and tissues more three-dimensional, which helps to judge their spatial positions and relationships.
