Description

Technical Field

[0001] The present invention relates to the medical field, and more specifically to an intelligent terminal device for 3D simulation teaching based on nasal endoscope operation technology. Background Art

[0002] With the rapid development of modern industry, the continuous progress of medical technology, and the gradual improvement of patients' health awareness, the application scope of nasal endoscopes is gradually expanding, which directly promotes the steady growth of market demand. Therefore, doctors or interns with certain experience are in short supply in the medical system. Among the teaching and training materials available on the market, the most commonly shown is the nasal cavity structure model, and there are relatively few nasal endoscope training devices developed in combination with the nasal cavity model. Moreover, the relevant foreign devices are expensive.

[0003] For example: CN217366657U, a new type of aspirator for rigid nasal endoscopes. The present utility model discloses a new type of aspirator for rigid nasal endoscopes, which includes an aspirator, a groove, and an aspiration end. The aspirator includes an L-shaped tube and a connection end, and the connection end is connected to one end of the short side of the L-shaped tube. An open groove is provided on the long side of the L-shaped tube, and the aspiration end is provided at one end of the long side of the L-shaped tube. The aspiration end is arc-shaped, and a hanging ring is provided on one side of the open groove close to the connection end. The present utility model can fix one end of the open groove on the tube body of the rigid nasal endoscope, so that the aspirator and the endoscope can enter the nasal cavity simultaneously, saving space. The aspiration end is arc-shaped, which is convenient for aspiration operation and can keep the field of view clear. It is easy to use and operate conveniently. The aspirator structure of the present utility model does not have an anti-flushing structure. If the aspiration cavity is blocked, it will affect the use, and its structural features are also common structures that those skilled in the art can flexibly adjust according to the actual situation.

[0004] For example: CN215274861U, a special suction device for nasal endoscopy surgery. The present utility model discloses a special suction device for nasal endoscopy surgery, which includes a suction main body and at least one set of auxiliary suction components and a main suction component respectively arranged on one side of the suction main body; the auxiliary suction component includes a first suction tube and a second suction tube respectively communicated with the suction main body through a first suction joint, and an L-shaped barrier member sleeved on the first suction tube and the second suction tube; at least one branch tube is arranged on the first suction tube at the barrier member section, and the branch tube passes through the side wall of the barrier member, so that the first suction tube is communicated with the outside of the barrier member through the branch tube; a suction head is arranged at the end of the second suction tube; one side of the suction main body opposite to the main suction component is connected with a negative pressure device arranged outside. The operation of the present utility model is simpler and more suitable for popularization and application. The structure of the suction device described in this utility model does not have an anti-flushing structure. If the suction cavity is blocked, it will affect the use, and its structural features are also common mechanisms that those skilled in the art can flexibly adjust according to the actual situation.

[0036] An intelligent terminal device for 3D simulation teaching of nasal endoscope operation technology according to the present invention has the following working principle: With the continuous progress of medical technology and the gradual improvement of patients' health awareness, the application scope of nasal endoscopes is gradually expanding, which directly promotes the steady growth of market demand. In order to train the operation technology of nasal endoscopes for staff, the present invention provides a training platform for nasal endoscope operation technology based on a nasal cavity model. This device realizes the debugging and control of all devices in the device through the chassis 103, which is the general term for the host and the controller. A display can be installed on the operation table 101, and after being connected to the chassis 103, it can realize the real-time viewing of the endoscope image. During the training process, aiming at the problem of blurred vision caused by blood contamination during nasal endoscope surgery, a multifunctional nasal endoscope 2 with "pulse flushing + suction integration" is designed to solve this situation. Its design purpose is to integrate independent flushing and suction channels in the nasal endoscope to achieve "one-key flushing + synchronous suction", and the training is carried out with the goal of restoring clear vision within 2 seconds. The PEEK triple-lumen tube 207 has a miniaturized layout of three channels. An optical cavity 209 is installed in the optical channel. Among them, the optical cavity 209 contains a camera and a fiber optic lighting component. The inner lining of the flushing channel is a PTFE anti-sticking layer 214. At the outlet of the flushing channel of the PEEK triple-lumen tube 207, there is a 30° conical diffuser nozzle 215, which can cover a 120° area in front of the lens. The suction cavity is designed with an eccentric side hole and is located in front of the optical cavity 209 to avoid blocking the vision during suction. Silicone umbrella valves B216 and silicone umbrella valves A210 are respectively provided in the flushing cavity and the suction cavity of the PEEK triple-lumen tube 207 to prevent blood backflow from contaminating the pipeline. Before the simulation training of the multifunctional nasal endoscope 2, adjust the tilt angle of the rubber nasal cavity model 321 according to the operator's body type. Loosen the adjustment bolt 314. When the rubber nasal cavity model 321 rotates, it drives the connecting rod 316 to rotate along the adjustment bolt 314 through the ball head fixing seat 318, the fixing screw 319, and the ball head fixing seat B320. When it is roughly convenient for the operator to operate, tighten the adjustment bolt 314. The adjustment bolt 314 rotates along the engagement of the fixed nut 315 and clamps and fastens the connecting rod 316 through the shaft seat 313. Subsequently, adjust the rotation angle of the rubber nasal cavity model 321 acting on the ball head 317 to simulate the effect of human cranial rotation. When the rubber nasal cavity model 321 rotates, it drives the ball head fixing seat 318 and the ball head fixing seat B320 to rotate along the ball head 317. In order to avoid uncontrolled deviation of the rubber nasal cavity model 321 due to the weight of itself and the attached components, install a fixing screw 319 in the ball head fixing seat 318 so that the fixing screw 319 generates friction with the ball head 317, and adjust this friction to debug the stability of the rubber nasal cavity model 321 when rotating along the ball head 317 and when the rotation stops. When the rubber nasal cavity model 321 rotates to the required angle and stops rotating, take the multifunctional nasal endoscope 2 from the nasal endoscope G fixing bracket 122 on the operation table 101.The front end of the multifunctional nasal endoscope 2 is inserted into the simulated nostril of the rubber nasal model 321 from the nasal model device 3. The rubber nasal model 321 is covered with sensors 326, as well as liquid outlets of pipeline group A308, pipeline group B310, and pipeline group C312. Three liquid outlets are provided in each pipeline group. When the multifunctional nasal endoscope 2 is inserted into the nasal model device 3, if the sensor feedback loop 208 in the PEEK three-lumen tube 207 is close to or touches the sensor 326 by a certain distance, the sensor 326 gives a signal to the chassis 103, and the controller in the chassis 103 controls the water pump 304 to start. Taking the pipeline group A308 as an example, the water pump 304 sucks the artificial blood in the liquid storage tank 302 through the pipeline G303, and the artificial blood The liquid is composed of carboxymethyl cellulose + red dye, which is injected into the liquid storage tank 302 after being prepared. The blood is transported to the solenoid valve B307 through the multi-directional pipe 306 through the spring-type telescopic pipe D305. At this time, the solenoid valve B307 is opened, and the pipe group A308 is subdivided into three pipes. The three pipes correspond to a number of sensors 326 respectively. When the sensor feedback loop 208 approaches or touches any sensor in the area corresponding to a single pipe, the artificial blood is transported to one of the pipes and discharged into the rubber nasal cavity model 321. The purpose is that when the sensor feedback loop 208 approaches or touches any sensor in the rubber nasal cavity model 321, the pipe transportation mechanism in the area where the sensor is located will be automatically triggered. The pipe group A308, the pipe The channel group B310, the pipeline group C312 and many sensors divide the inside of the rubber nasal cavity model 321 into several regional networks, so that when the multifunctional nasal endoscope 2 approaches or touches the inner surface of the nasal cavity, artificial blood will be automatically discharged, simulating the bleeding phenomenon when the real nasal endoscope touches the human nasal mucosa during operation. The operator observes the bleeding in the rubber nasal cavity model 321 on the display, and realizes one-key flushing + synchronous suction through the button of the button module 204 to ensure that the field of vision is restored in a short time. This is also one of the cores of the training of this equipment. The button of the button module 204 is a thumb-pressed linear control, which is specifically expressed as pressing force → flushing flow, and the equipment operation status is transmitted in real time through the status indicator 206. The indicator light 206 is green when it is not in status, which means it is in the ready state. When it flashes in blue, it means it is in the flushing state. When it is in the red state, it is a warning of suction chamber blockage, so that the operator can visually understand the equipment status. When cleaning begins, the piezoelectric ceramic pump 115 is started to suck up the flushing liquid in the flushing liquid storage box 113 through the pipe A114. The piezoelectric ceramic pump 115 is equipped with an embedded micro heating module 116 to heat the flushing liquid and maintain it in a warm state to avoid cold stimulation causing discomfort to the patient. The piezoelectric ceramic pump 115 transports the flushing liquid to the water inlet fixed cover 211 through the spring-type telescopic pipe A117, and then the solenoid valve A212 is opened, and the flushing liquid enters the solenoid valve A212. The solenoid valve A212 has one inlet and two outlets.The flushing liquid is transported from the first outlet through the pipe C213 to the flushing chamber in the PEEK three-lumen tube 207, and then pulse-sprayed outward by the 30° conical diffusion nozzle 215, and then the negative pressure suction module 120 is started. The negative pressure suction module 120 sequentially sucks the artificial blood and the flushing liquid mixture into the pipe B119 through the spring-type telescopic pipe B121, pipe D217, three-way joint 218, pipe F220, pressure sensor 221, and the PEEK three-lumen tube 207 suction chamber, and finally injects it into the antibacterial waste liquid storage box 118. During the suction, the pressure sensor 221 monitors the pressure in the suction chamber of the PEEK three-lumen tube 207 in real time. When blockage is detected, the negative pressure suction module 120 is closed, the solenoid valve A212 closes the first outlet, and opens the second outlet. The flushing liquid enters the pressure sensor 221 through the pipe E219, the three-way joint 218, and the pipe F220, and then is injected into the PEEK three-lumen tube 207 by the pressure sensor 221. The suction cavity of the cavity tube 207 is back-pulsed and flushed. After the dredging, the pressure sensor 221 detects the pressure change, and then closes the second outlet of the solenoid valve A212, and continues to open the negative pressure suction module 120 to suck the waste liquid into the antibacterial waste liquid storage box 118. The remaining flushing liquid in the rubber nasal cavity model 321 is collected into the antibacterial waste liquid storage box 118 through the spring-type telescopic pipe C123. Since there are many pipelines in this teaching device, in order to avoid the interference of the limited length of the pipeline on the various structures in the device, the spring-type telescopic pipe A117, the spring-type telescopic pipe B121, and the spring-type telescopic pipe C123 in this device are all telescopic structures in the form of spring coils. The multifunctional nasal endoscope 2 is connected to the handle control signal through the FPC flexible circuit. The FPC flexible circuit is wrapped by the control line 107, and is connected to the chassis 103 after connecting the hub 106. It is extended through the hub 106 for easy use by the operator. ,
