Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically relates to a 4K three-dimensional laparoscope. Background Art

[0002] The 4K three-dimensional laparoscope is an advanced medical device. Based on the traditional high-definition laparoscope system, it provides a more high-definition and realistic surgical field of view. This technology not only makes up for the deficiencies of conventional laparoscopes in image description, but also enhances the description of the details of the surgical field, making the surgical field of view clearer and more realistic, even better than that seen with the naked eye.

[0003] In order to display the display effect more clearly and stereoscopically, the 4K three-dimensional laparoscope usually sets an objective lens at the probe position for image shooting and recording. The objective lens enters an environment with a higher temperature (intraperitoneal) from a lower temperature (external). The surface temperature of the objective lens will be relatively low, and water vapor will condense on the surface of the objective lens to form a layer of fog, which will result in poor image acquisition and display effects at this time.

[0004] In view of this, a 4K three-dimensional laparoscope is proposed. Summary of the Invention

[0005] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this part, the abstract, and the title of the invention. However, such simplifications or omissions cannot be used to limit the scope of the present invention.

[0006] In view of the following technical problems existing in the prior art: In order to display the display effect more clearly and stereoscopically, the 4K three-dimensional laparoscope usually sets an objective lens at the probe position for image shooting and recording. The objective lens enters an environment with a higher temperature (intraperitoneal) from a lower temperature (external). The surface temperature of the objective lens will be relatively low, and water vapor will condense on the surface of the objective lens to form a layer of fog, which will result in poor image acquisition and display effects at this time.

[0007] To solve the above technical problems, the present invention provides the following technical solution: A 4K three-dimensional laparoscope, comprising an operating part, a catheter, and a detection head;

[0008] Both ends of the catheter are respectively docked with the operating part and the end of the detection head;

[0009] A flexible pad is docked and installed on the outer side of the bottom of the operating part. A positioning seat is arranged at a position close to the inside of the flexible pad. A heat pipe is docked on the surface of the operating part. One end of the heat pipe inserted into the operating part is docked on the inner wall of the top end of the positioning seat;

[0010] A guiding channel is provided in the catheter, and the guiding channel is used for guiding the trachea;

[0011] An installation groove is provided on the surface of the detection head. A camera is provided in the installation groove. An annular groove is provided on the inner edge of the installation groove, and an annular seat is provided in the annular groove.

[0012] As a preferred technical solution of a 4K three-dimensional laparoscope, a high-definition cable docking seat is docked at the bottom of the operation part. The back of the operation part can be docked with a suction valve for use in cooperation with a water supply nozzle. An angle knob is hinged on the side of the operation part.

[0013] As a preferred technical solution of a 4K three-dimensional laparoscope, a piston performs a sealed telescopic movement in the positioning seat. One end of the piston extending out of the positioning seat is docked with the surface of the flexible pad. When the flexible pad is pressed, the piston can perform a telescopic movement inside the positioning seat, so as to inject the gas above the positioning seat into the trachea. The heat pipe is externally connected to a hot air blower, which can heat the gas in the positioning seat.

[0014] As a preferred technical solution of a 4K three-dimensional laparoscope, a spring is provided on the inner wall of the flexible pad. One end of the spring away from the flexible pad is docked with the bottom wall of the operation part. The spring can enable the piston to reset after the pressing is cancelled, which is convenient for subsequent pressing again.

[0015] As a preferred technical solution of a 4K three-dimensional laparoscope, a water supply nozzle and a light guide window are provided on the surface of the detection head.

[0016] As a preferred technical solution of a 4K three-dimensional laparoscope, an objective lens is provided on the side of the camera facing outwards. A nozzle is provided on the inner edge surface of the annular seat. The center line of the nozzle coincides with the side of the objective lens away from the camera. At this time, the nozzle can preheat or clean the surface of the camera.

[0017] As a preferred technical solution of a 4K three-dimensional laparoscope, one end of the trachea away from the positioning seat penetrates through the guiding channel and is connected to the outside of the annular seat, so that the gas inside the positioning seat can be transported into the annular seat.

[0018] Advantages of the present invention:

[0019] 1. By reciprocally pressing the flexible pad of this 4K three-dimensional laparoscope, the hot air inside the positioning seat is injected into the annular seat through the trachea under the action of the piston. The position of the flexible pad is set close to the high-definition cable docking seat, making the overall operation relatively simple. When operating the high-definition cable docking seat during the inspection, the index finger can be lifted to operate the flexible pad, thereby improving the operation convenience of this endoscope;

[0020] 2. The 4K three-dimensional laparoscope directs a part of the gas directly at the objective lens through the nozzle, making the heat of the objective lens similar to the human body temperature, so as to ensure that atomization is not easily generated when the detection head enters the abdominal cavity, thereby improving the display effect of the image.

[0021] 3. The 4K three-dimensional laparoscope directs another part of the gas towards the surface of the objective lens through the nozzle. At this time, it can clean the liquid or debris on the surface of the objective lens, thereby ensuring the display effect of the image during the detection process.

[0022] 4. Under the action of the nozzle on the objective lens, the lens of the 4K three-dimensional laparoscope controls the temperature of the detection head through the hot air of external diffusion or internal blowing, thereby reducing the discomfort when the detection head is inserted into the abdomen.

[0035] Embodiment

[0036] Refer to Figure 1 、 23 are embodiments of the present invention, which provide a 4K three-dimensional abdominal endoscope, including an operation part 100, a catheter 200 and a detection head 300; both ends of the catheter 200 are respectively docked with the operation part 100 and the end of the detection head 300; a flexible pad 103 is docked and installed on the outer side of the bottom of the operation part 100, a positioning seat 105 is arranged at a position close to the inside of the flexible pad 103 in the operation part 100, a heat pipe 104 is docked on the surface of the operation part 100, one end of the heat pipe 104 inserted into the operation part 100 is docked on the inner wall of the top end of the positioning seat 105; a high-definition cable docking seat 101 is docked at the bottom of the operation part 100, wherein an aspiration valve can be docked on the back of the operation part 100 for cooperation with a water supply nozzle 301, and an angle knob 102 is hinged on the side of the operation part 100; a piston 106 performs a sealed telescopic movement in the positioning seat 105, and one end of the piston 106 extending out of the positioning seat 105 is docked with the surface of the flexible pad 103. When the flexible pad 103 is pressed, the piston 106 can perform a telescopic movement inside the positioning seat 105, so as to inject the gas above the positioning seat 105 into the trachea 108. The heat pipe 104 is externally connected to a hot air blower, which can heat the gas in the positioning seat 105; a spring 107 is arranged on the inner wall of the flexible pad 103, and one end of the spring 107 away from the flexible pad 103 is docked with the bottom wall of the operation part 100. Through the spring 107, the piston 106 can be reset after the pressing is cancelled, facilitating subsequent pressing again;

[0037] Referring to Figure 2 , a guiding channel 201 is opened in the catheter 200, and the guiding channel 201 is used for guiding the trachea 108;

[0038] Referring to Figure 1 , 2 , 4 and 5, an installation groove 303 is opened on the surface of the detection head 300, a camera 304 is arranged in the installation groove 303, an annular groove 306 is opened on the inner edge of the installation groove 303, and an annular seat 307 is arranged in the annular groove 306; a water supply nozzle 301 and a light guide window 302 are arranged on the surface of the detection head 300; an objective lens 305 is arranged on the side of the camera 304 facing outwards, and a nozzle 308 is arranged on the inner edge surface of the annular seat 307. The center line of the nozzle 308 coincides with the side of the objective lens 305 away from the camera 304. At this time, the nozzle 308 can preheat or clean the surface of the camera 304; one end of the trachea 108 away from the positioning seat 105 penetrates through the guiding channel 201 and is connected to the outside of the annular seat 307, so that the gas inside the positioning seat 105 can be transported into the annular seat 307.

[0039] Through this embodiment, the following can be achieved: during use, the gas inside the positioning seat 105 can be heated by an externally connected hot air blower (during this process, the temperature is controlled at 36 - 40 °C, which is adapted according to the normal human body temperature and will avoid the consumption of gas during transportation according to the length of the trachea 108). During operation, the flexible pad 103 is pressed reciprocally. At this time, the piston 106 can change its position in the positioning seat 105, so that the hot air in the positioning seat 105 can be injected into the annular seat 307 through the trachea 108. The annular seat 307 injects the gas into two positions of the objective lens 305 through the nozzle 308. One is to directly preheat the objective lens 305 to ensure that the heat of the objective lens 305 is similar to the human body temperature, so as to ensure that the detection head 300 is not easily atomized when entering the abdominal cavity, thereby improving the image display effect. The other is to blow air on the surface of the objective lens 305, which can clean the liquid or debris on the surface of the objective lens 305 at this time, thereby ensuring the image display effect (the same effect can also be achieved when the detection head 300 is inserted into the abdominal cavity in this step). At the same time, when the hot air reaches the position of the nozzle 308, it can play a certain temperature control effect on the detection head 300, thereby reducing the discomfort when the detection head 300 is inserted into the abdomen).

[0040] It should be understood that in the development process of any actual implementation, in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those ordinary technical personnel who benefit from this disclosure, without excessive experimentation, the development efforts will be a routine work of design, manufacturing, and production.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
