Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a foreign body removal device for the oral cavity in the emergency department. Background Technology

[0002] Foreign bodies in the throat are a common condition seen in otolaryngology outpatient and emergency departments. There are many types of foreign bodies, including animal bones, dentures, and others. If the diagnosis is clear and the condition is treated properly, it generally will not lead to serious consequences. However, if the type of foreign body is unusual, the symptoms are atypical, or the foreign body has fallen from the throat into the trachea or esophagus, or if a secondary infection occurs, it often leads to more serious complications. In some cases, it can even be life-threatening. Therefore, it is important to diagnose and treat foreign bodies in the throat as early as possible.

[0003] The shortcomings of existing methods for removing foreign objects from the mouth:

[0004] (1) The existing cleaning method requires opening the oral cavity and pharynx with a video laryngoscope, and then using other clamping tools to enter the pharynx and observe with the video laryngoscope to remove the foreign object. This requires a step-by-step operation. When inserting and removing the clamping tools, the channel becomes smaller and the operating space becomes narrow due to the presence of the opening object and the video laryngoscope, which increases the difficulty of operation. Furthermore, the removal of the foreign object may cause secondary injury.

[0005] (2) Some existing foreign body removal devices have inaccurate suction control and cannot adjust the suction force according to the viscosity of secretions. Excessive suction force will damage the oral mucosa, while insufficient suction force will result in ineffective cleaning.

[0006] (3) Some existing foreign body removal devices are difficult to reach deep into the oral cavity to remove foreign bodies, and it is difficult to adjust the angle of the cleaning head. The operation is not flexible enough, resulting in some areas where foreign bodies cannot be reached. Summary of the Invention

[0025] Preferably, the head positioning block and the side positioning block are covered with a soft pad on the working surface.

[0026] Preferably, the expanding piece is trapezoidal, wider at the top and narrower at the bottom.

[0027] Preferably, the bottom of the smart VR glasses is equipped with a shadowless lamp.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] (1) The present invention has a head positioning component designed to accurately position the head of critically ill patients, avoiding the inconvenience caused by the patient's unconscious head shaking. At the same time, the head positioning component adopts a triangular positioning structure of head positioning block and two sets of adjustable positioning components, which solves the problem of poor adaptability of traditional positioning and can adapt to the head size of patients of different ages (such as children and adults) and different body types. The working surfaces of the head positioning block and the side positioning block are covered with soft pads to avoid the hard structure from directly contacting the patient's head skin and eliminate the risk of head injury.

[0030] (2) This invention eliminates the traditional manual operation of opening the patient's mouth by designing a mouth opening component. It improves the efficiency of medical work by automatically driving the hydraulic cylinder. At the same time, the mounting seat can move up and down along the fixed support rod through the positioning screw, which can accurately adjust the height of the opening component according to the height of the patient's head and the position of the oral cavity, ensuring that the opening piece is accurately aligned with the interdental space and avoiding the time-consuming repeated adjustments. The opening piece is designed as a trapezoid with a larger top and a smaller bottom, which makes it easier and faster to embed into the patient's interdental space (especially for critically ill patients who may have trismus or relaxed oral muscles). Compared with the traditional rectangular opening piece, the embedding efficiency is improved and the patient's oral discomfort is reduced.

[0031] (3) This invention is designed with a foreign object grasping component and uses a universal adjustment component spliced ​​with multiple universal ball joints. With the help of the adjustment servo motor and guide wire control, it can achieve flexible turning in 360° direction and can penetrate into narrow areas in the oral cavity (such as the throat and gum gaps), avoiding the blind spots of traditional straight rod grasping tools that are "unreachable and cannot be turned". At the same time, the camera probe at the end of the ball joint can transmit the image of the foreign object in the oral cavity to the smart VR glasses in a synchronous manner, and medical staff can accurately locate the position of the foreign object through clear images.

[0032] (4) The present invention is designed with a foreign object suction component. The suction tube is equipped with an electrode point near the working end. When liquid foreign objects flow through, the flow rate can be sensed and the data can be synchronized to the smart VR glasses. Medical staff can observe the flow rate changes in real time. When the flow rate decreases, the suction force of the conventional suction device can be reduced in time to avoid negative pressure damage to the oral mucosa (such as the fragile mucosa of the pharynx) caused by continuous strong suction.

[0033] (5) The present invention is designed with smart VR glasses, which can simultaneously receive image information of the clamping component and liquid flow information of the suction component, so that medical staff do not need to frequently switch observation devices, thus improving the continuity of operation;

[0034] The VR glasses have an integrated shadowless light at the bottom, which can directly illuminate the inside of the oral cavity, assisting medical personnel in observing the condition inside the patient's oral cavity, helping them to quickly locate the foreign object, and improving the efficiency of foreign object removal.

Detailed Implementation

[0051] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0052] like Figure 1 As shown, the present invention provides an emergency department critical oral foreign body removal device, which consists of a head positioning component 1, a support component 2, a mouth opening component 3, a foreign body clamping component 4, a foreign body suction component 5, and a smart VR glasses 6.

[0053] Among them, the bracket assembly 2 is set on the head positioning assembly 1, the mouth opening assembly 3 and the smart VR glasses 6 are assembled on the bracket assembly 2, and the foreign object clamping assembly 4 and the foreign object suction assembly 5 are both connected to the smart VR glasses 6 through an electric control line.

[0054] Specifically, such as Figure 2 As shown, the head positioning component 1 consists of a base plate 101, a head positioning block 102, and an adjustment positioning component 103. The head positioning block 102 is fixedly installed at one end of the base plate 101 and is used to fit and position the top area of ​​the patient's head. There are two sets of adjustment positioning components 103, which are respectively installed on the left and right sides of the base plate 101, near the head positioning block 102. The three form a triangular area. By adjusting the adjustment positioning component 103, head positioning can be performed for patients of different ages and body types to ensure the positioning of the head during the removal of foreign objects from the oral cavity. This avoids failure of foreign object removal or mechanical damage to the oral cavity caused by the patient's unconscious shaking or turning of the head, thus ensuring the smooth progress of the foreign object removal work. A set of fixing seats 104 is provided on the base plate 101, through which the assembly of the support component 2 is realized.

[0055] like Figure 3As shown, the adjusting positioning assembly 103 consists of a side positioning block 103a, a base 103b, and an adjusting screw 103c. The base 103b is fixedly mounted on one side of the base plate 101. An internal threaded hole 103d is provided on the base 103b, and guide holes 103e are provided on both sides of the internal threaded hole 103d. The adjusting screw 103c is assembled onto the base 103b through the internal threaded hole 103d. One end of the adjusting screw 103c is provided with a mating bearing 103f, and the end away from the mating bearing 103f is provided with an adjusting knob 103g. The side positioning block 103a is assembled through the mating bearing 103f. A mating groove 103h is provided in the middle of the rear end of the side positioning block 103a. The mating bearing 103f is assembled through the mating groove 103h. A guide rod 103i is provided on the side, which passes through a guide hole 103e. Thus, by rotating the adjustment knob 103g, the adjustment screw 103c is driven to rotate. Because the adjustment screw 103c is threadedly engaged with the internal threaded hole 103d, the adjustment screw 103c can reciprocate linearly along the internal threaded hole 103d, thereby driving the side positioning block 103a to also reciprocate linearly. To prevent the rotation of the adjustment screw 103c from causing the side positioning block 103a to rotate, a docking bearing 103f is provided to engage with the docking groove 103h, thus preventing the side positioning block 103a from rotating. At the same time, the engagement of the guide rod 103i with the guide hole 103e ensures that the side positioning block 103a will not wobble, thus ensuring the smooth positioning of the patient's head side.

[0056] like Figure 4 As shown, the support assembly 2 consists of a fixed support rod 201, an adjustable support frame 202, and an adjusting nut 203. There are two fixed support rods 201, each mounted on a fixed seat 104 of the head positioning assembly 1. The mouth opening assembly 3 is mounted on one of the fixed support rods 201. An assembly frame 204 is located in the middle of the adjustable support frame 202, through which the smart VR glasses 6 are mounted. Hollow rods 205 are located at both ends of the bottom of the adjustable support frame 202. The fixed support rods 201 are inserted into the hollow rods 205, allowing the adjustable support frame 202 to move freely up and down. The end of the hollow rod 205 closest to the fixed support rod 201... A tapered external thread section 206 is provided, and a through groove 207 is opened in the middle of the tapered external thread section 206. An adjusting nut 203 is assembled on the tapered external thread section 206. By rotating the adjusting nut 203, the inner diameter of the hollow rod 205 can be adjusted in conjunction with the tapered external thread section 206. Thus, when the inner diameter of the hollow rod 205 is normal, the adjusting support frame 202 can move freely up and down along the adjusting support frame 202 to adjust the height of the smart VR glasses 6. When the adjusting nut 203 is tightened to shrink the inner diameter of the hollow rod 205, the adjusting support frame 202 can be fixed on the fixed support rod 201 to achieve fixed support for the smart VR glasses 6.

[0057] like Figures 5-6 As shown, the mouth-opening assembly 3 consists of a mounting base 301, a hydraulic cylinder 302, a shaft 303, a pair of arc rods 304, a pair of hinge rods 305, and an opening member 306. The mounting base 301 has mounting holes 301a, through which it is mounted to the fixed support rod 201. The hydraulic cylinder 302 is mounted inside the mounting base 301, and the shaft 303 is connected to the output end of the hydraulic cylinder 302. A pair of hinge seats 307 are provided on both sides of the mounting base 301 near the shaft 303. One end of each of the two arc rods 304 is hinged to one of the two... At the hinge seat 307 on the side, the opening member 306 is assembled on the arc rod 304 at the end away from the junction seat. The bottom of the opening member 306 is provided with an opening piece 306a. The shaft 303 is provided with a hinge joint 303a at the end away from the hydraulic cylinder 302. One end of the two hinge rods 305 is hinged to the hinge joint 303a, and the other end is hinged to the middle of the arc rod 304. In this way, the hydraulic cylinder 302 drives the shaft 303 to advance or retract, thereby driving the two arc rods 304 and the opening member 306 to open and close, thus opening the patient's mouth.

[0058] The mounting base 301 has a threaded positioning hole 301b on one side, and a positioning screw 301c is installed in the threaded positioning hole 301b. By screwing the positioning screw 301c in and out, the mounting base 301 can be tightened or loosened relative to the fixed support rod 201, thereby adjusting the up and down position of the mouth opening component 3 on the fixed support rod 201. In this way, the precise positioning of the patient's mouth can be achieved, ensuring the smooth progress of subsequent mouth opening work.

[0059] like Figures 7-11 As shown, the foreign object gripping assembly 4 consists of a gripping handheld body 401, a universal adjustment assembly 402, and a gripping component 403. The universal adjustment assembly 402 is mounted on one end of the gripping handheld body 401, and the gripping component 403 is mounted inside the gripping handheld body 401 and the universal adjustment assembly 402. A camera probe 404 is provided at the end of the universal adjustment assembly 402 near the gripping component 403, and a wire 405 is provided at the end of the gripping handheld body 401 away from the universal adjustment assembly 402. The wire 405 is connected to the smart VR glasses 6, and the image captured by the camera probe 404 can be synchronized with the smart VR glasses 6. A control button 406 is provided on the gripping handheld body 401, which can remotely control the universal adjustment assembly 402 and the gripping component 403.

[0060] The gripping handpiece 401 has a gripping through hole 401a inside, and the gripping part 403 is assembled in the gripping through hole 401a. There are six universal through holes 401b arranged around the gripping through hole 401a.

[0061] The universal adjustment assembly 402 consists of several universal ball joints 402a, an adjustment servo motor 402b, a guide wire 402c, and a head ball joint 402d. The main body of the universal ball joint 402a is a large-diameter ball 407. The bottom of the large-diameter ball 407 is provided with a small ball head 408. The interior of the large-diameter ball 407 and the small ball head 408 is provided with a through hole 409. The large-diameter ball 407 is provided with a ball groove 410 for fitting the small ball head 408 away from the small ball head 408. Several universal ball joints 402a The main body of the universal adjustment assembly 402 is formed by sequentially splicing together the small ball head 408 with the ball groove 410. The outer side of the large diameter ball 407 is arranged with six universal rings 411 along the central axis. The first end ball joint 402d is the same as the universal ball joint 402a in the large diameter ball 407 part, but the bottom of the first end ball joint 402d is not the small ball head 408, but is provided with a clamping tube 412. The clamping tube 412 is connected to the through hole 409. A limiting protrusion ring is provided in the through hole 409 of the first end ball joint 402d. 412a, When the universal adjustment assembly 402 is connected to the gripping handpiece body 401, the through hole 409 and the gripping tube 412 are connected to the gripping through hole 401a. The six universal rings 411 are also axially aligned with the six universal through holes 401b. The number of adjustment servos 402b is the same as that of the universal through holes 401b, and they are respectively assembled on the gripping handpiece body 401 and axially aligned with the universal through holes 401b. One end of the guide wire 402c is connected to the power end of the adjustment servo 402b, and the rest passes through the universal through holes 401b. The universal joint 402 is connected to the through hole 401b and the universal ring 411. The end of the universal ring 411 that is furthest away from the adjusting servo 402b is connected to the first ball joint 402d. When the universal adjustment assembly 402 is adjusted by the control button 406, the guide wires 402c in the six adjusting servos 402b will retract in the corresponding direction. Under the pull of the guide wires 402c, the universal ball joint 402a and the first ball joint 402d will rotate in the direction, thus realizing universal adjustment, which can be used by medical personnel to remove foreign objects in the patient's oral cavity.

[0062] The camera probe 404 is located at the end of the first ball joint 402d. Thus, when the universal adjustment component 402 is working, the camera probe 404 can follow and capture images at the corresponding angles and transmit them to the smart VR glasses 6, which makes it easier for medical personnel to observe the inside of the patient's mouth and helps them to remove foreign objects from the patient's mouth smoothly.

[0063] The clamping component 403 consists of a chuck 403a, a slider 403b, a cable 403c, and a clamping servo motor 403d. The clamping servo motor 403d is assembled inside the clamping handpiece body 401, axially coinciding with the clamping through hole 401a. The slider 403b is located below the limiting protrusion 412a inside the clamping tube body 412. A return spring 403e is sleeved on the outside of the slider 403b, with one end of the return spring 403e connected to the limiting protrusion 412a. One end of the cable 403c is connected to the power end of the clamping servo motor 403d, and the other end is connected to the slider 403b. The head 403a is mounted on the end of the slider 403b away from the cable 403c and extends out of the clamping tube 412. When the clamping servo 403d retracts the cable 403c, the slider 403b moves upward, causing the clamp 403a to retract into the clamping tube 412. At this time, the clamp 403a will close due to being retracted into the clamping tube 412, forming a clamping action on foreign objects. When the servo moves the cable 403c back, the return spring 403e rebounds, helping the slider 403b to move downward, thereby causing the clamp 403a to extend out of the clamping tube 412 again, thus opening. This realizes the opening and closing operation of the clamping body.

[0064] like Figures 12-13 As shown, the foreign body suction assembly 5 includes a suction handheld body 501 and a suction tube 502. The suction tube 502 is assembled at one end of the suction handheld body, and the tail end of the suction tube 502 is connected to a suction pipe 503. The suction pipe 503 extends out of the suction handheld body 501 and is connected to a conventional suction device to provide suction for the suction tube 502. A set of electrode points 504 is provided inside the suction tube 502 near the working end. The tail end of the suction handheld body 501 is provided with a wire 405, which is connected to the smart VR glasses 6. When the foreign body suction assembly 5 is working, the liquid passing through the suction tube 502 will pass through the electrode points 504, thereby sensing the flow rate of the liquid foreign body. At the same time, it will be displayed on the smart VR glasses 6. When the amount of liquid passing through decreases, the medical personnel can understand it immediately and reduce the suction, thereby protecting the patient's oral cavity tissue.

[0065] The smart VR glasses 6 are mounted on the bracket assembly 2. They can receive and display image information and liquid foreign body flow information from the foreign body retrieval assembly 4 and the foreign body suction assembly 5. Medical personnel can use the smart VR glasses 6 to understand the situation of foreign bodies inside the patient's mouth in real time and intuitively, ensuring the smooth progress of foreign body removal.

[0066] Furthermore, the head positioning block 102 and the side positioning block 103a are covered with soft pads 105 on the working surface, so as to ensure comfort when positioning the patient's head and avoid the hard structure from bumping and injuring the patient's head.

[0067] Furthermore, the expander 306a is trapezoidal with a larger top and a smaller bottom, making it easier to insert between the patient's teeth and facilitate quick opening of the patient's mouth.

[0068] Furthermore, such as Figure 14 As shown, the bottom of the smart VR glasses 6 is equipped with a shadowless lamp 601. The shadowless lamp 601 helps medical personnel to more clearly observe the location of foreign objects in the patient's mouth, ensuring the smooth completion of the removal work.

[0069] The specific implementation process is as follows:

[0070] When starting the foreign body removal procedure for critically ill patients, medical personnel place the patient's head on the base plate 101 of the head positioning component 1. First, the top of the patient's head is placed against the head positioning block 102. At this time, the medical personnel start to rotate the adjustment knob 103g, which drives the adjustment screw 103c to rotate. The side positioning blocks 103a on both sides are adjusted according to the patient's condition. After they are in contact with the patient's side, the head positioning work is quickly completed.

[0071] After the patient's head is positioned, the medical personnel quickly adjust the position of the mouth opening component 3 relative to the patient's mouth using the positioning screw 301c, insert the opening piece 306a between the patient's teeth, and activate the hydraulic cylinder 302 to open and close the opening piece 306, thus quickly completing the opening of the patient's mouth.

[0072] After opening the patient's mouth, medical personnel begin removing the foreign object using smart VR glasses 6, foreign object retrieval component 4, and foreign object suction component 5. First, the shadowless lamp 601 below the smart VR glasses 6 is turned on to illuminate the patient's mouth. The foreign object retrieval component 4 and foreign object suction component 5 are then inserted into the patient's mouth. The camera probe 404 transmits the captured images to the smart VR glasses 6, allowing medical personnel to clearly observe the situation inside the patient's mouth. Once the location of the solid foreign object is determined, the universal adjustment component 4 is adjusted using control button 406. In the direction of 02, the clamping component 403 is controlled by the control button 406 to clamp out the solid foreign object; if there is a liquid foreign object, it is sucked up by the foreign object suction component 5. When the foreign object suction component 5 is working, the liquid foreign object passing through the suction tube 502 will pass through the electrode point 504, thereby sensing the flow rate of the liquid foreign object. At the same time, it will be displayed on the smart VR glasses 6. When the amount of liquid passing through decreases, the medical personnel can understand it immediately and reduce the suction force to protect the patient's oral cavity tissues; thus completing the entire process of removing foreign objects from the patient's oral cavity.
