Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to a visual throat foreign body treatment and suction auxiliary device. Background Art

[0002] Foreign bodies stuck in the throat are a common disease for emergency visits by patients in the otolaryngology department. When performing throat examinations and removing foreign bodies, a frontal mirror, indirect laryngoscope, and foreign body forceps are required at the same time. When using an indirect laryngoscope to remove foreign bodies from the throat, the patient or his family members are required to cooperate in pulling the tongue to fully expose the pharyngeal cavity. The doctor holds the indirect laryngoscope in one hand to determine the location of the foreign body, and holds the foreign body forceps in the other hand to clamp and remove the foreign body. However, patients often have low cooperation or difficulty mastering the essentials of tongue traction, which makes it difficult to expose the pharyngeal cavity and make it impossible to successfully remove foreign bodies in the throat. Repeated attempts to clamp foreign bodies will increase patient discomfort and delay the efficiency of emergency work.

[0003] Furthermore, if the foreign body is stuck due to eating, there are usually more secretions and food residues in the mouth and throat, which interfere with the location and diagnosis of the foreign body. In the prior art, Chinese medicine practitioners hold the indirect laryngoscope and foreign body forceps in both hands during foreign body diagnosis, which makes it difficult to remove the interfering secretions and residues. Therefore, there is a problem that the foreign body forceps may injure the throat mucosa due to the blind spot of vision caused by the interference of secretions and food residues during the foreign body removal process, resulting in an increased risk of bleeding or subsequent infection.

[0004] In view of this, it is necessary to improve the throat foreign body treatment device in the prior art to solve the above problems. It should be noted that the above introduction to the background technology is only for the convenience of a clear and complete description of the technical solution of the present application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application. Summary of the invention

[0005] The purpose of the present invention is to disclose a visualized throat foreign body treatment and suction auxiliary device to solve the problem that the existing throat foreign body treatment device cannot smoothly remove the foreign body due to poor exposure caused by the narrow pharyngeal cavity and complex anatomical structure, and the problem that the field of vision is unclear due to the interference of secretions and food residues, which leads to damage to the throat mucosa during the foreign body removal process.

[0014] After passing through the connecting portion, the force-applying assembly is located above the connecting section in the connecting port. The force-applying assembly includes a first force-applying member and a second force-applying member assembled on both sides of the negative pressure straw. The first force-applying member is pressed to move toward the second force-applying member. The first force-applying member and the second force-applying member simultaneously apply force to both sides of the negative pressure straw to cause elastic deformation of the negative pressure straw.

[0015] As a further improvement of the present invention, a first guide channel is provided in the accommodating section, and the negative pressure suction tube passes through the first accommodating channel provided in the conduit and enters the first guide channel, and is guided by the first guide channel to between the first force applying member and the second force applying member, and then is inserted into the collecting device;

The laryngoscope handle is held so that the catheter drives the optical lens to extend into the throat, and the throat image captured by the optical lens is displayed by the display device, so as to determine the stuck position of the foreign body. When there are secretions and food residues in the throat that interfere with the determination of the stuck position of the foreign body, the secretions and food residues are attracted to the collection device through a negative pressure straw, so that the optical lens can collect the undisturbed throat image and present it on the display device to achieve the purpose of determining the stuck position of the foreign body. Finally, another handheld foreign body forceps is inserted into the receiving port of the laryngoscope handle and the clamping part of the foreign body forceps is extended into the throat from the second receiving channel and accurately clamps the foreign body stuck in the throat, and the foreign body forceps are kept in the state of clamping the foreign body so that the foreign body forceps are withdrawn from the laryngoscope handle as a whole, completing the entire foreign body treatment step. Through the above steps, a clear picture of the throat can be obtained and the exact location of the foreign body can be determined by holding the laryngoscope handle with one hand. The negative pressure suction tube can be used to remove secretions in the throat in real time, so that the accuracy of determining the location of the foreign body can be further improved, thereby effectively improving the efficiency of handling foreign bodies in the throat and effectively avoiding bleeding and subsequent infection caused by mistakes.

[0035] Ginseng Figures 2 to 8 As shown, the laryngoscope handle 2 is equipped with an optoelectronic component 41 and an illumination optical fiber 42, and a third accommodating channel 33 is formed in the catheter 3 along the length direction. An imaging optical fiber 43 is passed through the third accommodating channel 33, and one end of the imaging optical fiber 43 is connected to the optoelectronic component 41 and the illumination optical fiber 42, and the other end of the imaging optical fiber 43 is connected to the optical lens 4. The laryngoscope handle 2 has a accommodating section 21 and a gripping section 22. The accommodating section 21 and the gripping section 22 enclose a accommodating cavity 23 for accommodating the optoelectronic component 41 and the illumination optical fiber 42, and the axis of the accommodating section 21 and the axis of the gripping section 22 form an angle greater than 100°; the catheter 3 is connected to the end of the accommodating section 21 away from the gripping section 22, and the outer wall of the accommodating section 21 forms a connecting portion 211, and the collecting device 71 is detachably connected to the connecting portion 211, and the connecting portion 211 forms a force-applying component 25 for pressing the negative pressure suction tube 7.

[0036] It should be noted that the optoelectronic component 41 and the illumination optical fiber 42 are all gathered at the connecting line 51, the connecting line 51 is passed through the end of the gripping section 22 of the laryngoscope handle 2 and connected to the plug 52, and is connected to the display device 5 through the plug 52, and the optoelectronic component 41 has a circuit component 412 and an imaging lens 411, and the illumination optical fiber 42 is led out from the plug 52 and extends in the connecting line 51 to Figure 5 The position shown in FIG. 1 is to provide illumination to the imaging lens 411, and the imaging lens 411 and the imaging optical fiber 43 (see FIG. Figure 8The image of the pharynx collected by the optical lens 4 is transmitted to the display device 5 through the imaging optical fiber 43 and the imaging lens 411, the circuit component 412, the connecting line 51 and the plug 52. With the above design, the image of the pharynx can be clearly displayed on the display device 5 by holding the grip section 22 of the laryngoscope handle 2 with one hand so that the optical lens 4 is inserted into the pharynx, and it is not limited by the patient's cooperation and whether the pharynx exposure method is mastered, which facilitates the determination of the embedded position of foreign objects and the removal of foreign objects.

[0037] Ginseng Figures 5 to 7 As shown, the connecting portion 211 has a connecting port 212 in the center thereof which is connected to the accommodating chamber 23, and the collecting device 71 has a connecting section 711 which is adapted to the connecting port 212, and the collecting device 71 is detachably connected to the connecting port 212 through the connecting section 711 so as to be connected to the laryngoscope handle 2; after the force-applying component 25 passes through the connecting portion 211, it is located above the connecting section 711 in the connecting port 212, and the force-applying component 25 includes a first force-applying member 251 and a second force-applying member 252 which are assembled on both sides of the negative pressure suction tube 7, and the first force-applying member 251 is pressed to displace the first force-applying member 251 in a direction close to the second force-applying member 252, and the first force-applying member 251 and the second force-applying member 252 simultaneously apply force to both sides of the negative pressure suction tube 7 to elastically deform the negative pressure suction tube 7.

[0038] It should be noted that the specific Figure 7 As shown, the first force-applying member 251 includes, arranged from right to left, a button 2511, a pressure member 2512, a connecting rod 2513, and an elastic reset member 2514. Figure 1 and Figure 2As shown, the connecting portion 211 is integrally formed just below the accommodating section 21, and a receiving groove 26 for the button 2511 to be placed is provided on the side of the connecting portion 211 close to the conduit 3, one end of the elastic reset member 2514 is fixedly connected to the bottom of the receiving groove 26, and the other end is fixed to the button 2511. One end of the connecting rod 2513 is fixedly connected to the button 2511, and the other end is axially inserted into the elastic reset member 2514, passes through the bottom of the receiving groove 26, and then enters the connecting port 212 and connects to the pressure member 2512. Specifically, the pressure member 2512 and the second force member 252 are both arranged as arc surfaces on one side close to each other. After the throat image collected by the optical lens 4 is displayed on the display device 5, if there are more secretions or food residues in the throat, it may affect the judgment of the position of the foreign body. At this time, by pressing the button 2511 to push the connecting rod 2513 to drive the pressure piece 2512 to press the negative pressure suction tube 7 to make it elastically deformed, and the second force-applying member 252 arranged on the opposite side of the first force-applying member 251 simultaneously applies pressure to the other side of the negative pressure suction tube 7, and the pressure of the negative pressure suction tube 7 is changed by pressing to achieve the purpose of sucking the secretions in the throat, and the purpose of removing the secretions in the throat is achieved by pressing the button 2511 multiple times. After the secretions enter the negative pressure suction tube 7, they flow in the negative pressure suction tube 7 and are temporarily stored in the collection device 71. And, when the button 2511 is released, the elastic reset member 2514 returns to a state without force, so that the button 2511 moves out of the receiving groove 26 and drives the pressure piece 2512 back to a state of not contacting the negative pressure suction tube 7. Through the above scheme, the negative pressure suction tube 7 can effectively remove the secretions in the throat, and the display device 5 can more clearly display the image of the throat without the interference of secretions, further improving the accuracy of the judgment of the position of the foreign body, so that the foreign body can be accurately and quickly removed by the foreign body forceps 6 while avoiding the problem of mucosal damage.

[0039] Ginseng Figures 2 to 8As shown, a first guide channel 213 is provided in the accommodating section 21, and the negative pressure suction pipe 7 is inserted into the first guide channel 213 through the first accommodating channel 31 provided in the conduit 3, and is guided by the first guide channel 213 to between the first force-applying member 251 and the second force-applying member 252, and then inserted into the collecting device 71; the first guide channel 213 has a horizontal channel 2131 connected to the first accommodating channel 31 and a vertical channel 2132 connected to the connecting port 212, and the horizontal channel 2131 and the vertical channel 2132 are smoothly transitioned and connected. Specifically, the negative pressure suction pipe 7 and the collecting device 71 are disposable medical devices, and need to be replaced to avoid cross infection. When replacing the negative pressure suction pipe 7 and the collecting device 71, first connect the collecting device 71 to the connecting port 212, and the connecting section 711 of the collecting device 71 can be detachably connected to the connecting port 212 by means of threads or snap-on connection. Then, the negative pressure suction tube 7 is inserted into the first accommodating channel 31 from the end of the catheter 3 away from the laryngoscope handle 2. The negative pressure suction tube 7 is inserted along the length direction of the first accommodating channel 31 and passes through the first force-applying member 251 and the second force-applying member 252 under the guidance of the horizontal channel 2131 and the vertical channel 2132 and is inserted into the connecting section 711 of the collecting device 71. Through the first guiding channel 213 formed by the horizontal channel 2131 and the vertical channel 2132, the negative pressure suction tube 7 can be effectively guided in the direction of the accommodating chamber 23 so that it can be smoothly docked with the collecting device 71. Further, when replacing the negative pressure suction tube 7 and the collecting device 71, firstly, the end of the negative pressure suction tube 7 passing through the catheter 3 and the entire catheter 3 are rinsed to remove the secretions attached to the outer wall of the negative pressure suction tube 7. Then, the collecting device 71 is removed from the connecting portion 211, and then pressure is applied to the end of the negative pressure suction tube 7 passing through the connecting port 212 to move the negative pressure suction tube 7 out of the catheter 3 and the laryngoscope handle 2 as a whole. Specifically, since a certain amount of pollutants may adhere to the outer wall of one end of the negative pressure suction tube 7 inserted into the collection device 71, the above-mentioned disassembly method can effectively avoid the possibility of contamination of the laryngoscope handle 2 and the catheter 3 caused by the pollutants.

[0040] Ginseng Figures 2 to 8As shown, the accommodating opening 24 is opened on the outer wall of the gripping section 22, and a second guide channel 214 is formed in the accommodating section 21. One end of the second guide channel 214 is connected to the accommodating opening 24, and the other end is connected to the second accommodating channel 32 opened in the catheter 3. The inner diameter of the end of the second guide channel 214 connected to the second accommodating channel 32 is smaller than the inner diameter of the accommodating opening 24. The inner diameter of the second accommodating channel 32 is larger than the width of the clamping portion 62 of the foreign body forceps 6 in the combined state. It should be noted that after the image of the throat after the secretions are removed is presented on the display device 5, the medical staff holds the gripping section 22 of the laryngoscope handle 2 with one hand, and after the other hand completes the action of pressing the button 2511, the gripping portion 61 of the foreign body forceps 6 can be held by hand so that the gripping portion 62 and the connecting member 63 connecting the gripping portion 62 and the gripping portion 61 are sequentially extended into the accommodating opening 24, the second guide channel 214, the second accommodating channel 32, and finally pass through the end of the catheter 3. At this time, the position of the foreign body stuck can be accurately determined through the throat image displayed by the display device 5. Since the opening of the accommodating opening 24 and the second guide channel 214 presents a certain taper, and the second accommodating channel 32 has an inner diameter that is larger than the width of the clamping portion 62 in the closed state and larger than the diameter of the connecting member 63, the gripping portion 61 of the handheld foreign body forceps 6 can control the movement of the foreign body forceps 6 as a whole in the laryngoscope assembly 1 in four relatively free directions (front, back, left, and right), so that the clamping portion 62 can more smoothly clamp the foreign body and remove it from the throat.

[0041] Ginseng Figures 1 to 4 As shown, a guide end piece 34 is formed at one end of the catheter 3 away from the laryngoscope handle 2, and the optical lens 4, the clamping portion 62 of the foreign body forceps 6 and the negative pressure suction tube 7 are all passed through the end face of the guide end piece 34 away from the catheter 3, and the outer wall of the guide end piece 34 is formed with a taper. The guide end piece 34 is connected to the catheter 3 through a snake tube 35. It should be noted that the catheter 3 in this embodiment is selected as an elastic material (such as medical rubber, etc.), and its direction is difficult to control due to its relatively soft texture. In this embodiment, the guide end piece 34 is selected as a device with rigidity (for example, metal titanium). Due to its certain hardness, under the guidance of the guide end piece 34, it is easier to control the catheter as a whole 3 to extend into the throat. Further, the end face of the guide end piece 34 is formed with a round chamfer, and is formed as a tapered outer wall, which can effectively avoid the possibility of mucosal contusion caused by the sharp part.

[0042] Secondly, in this embodiment, the snake tube 35 is selected as an endoscope snake tube, which is composed of multiple small sections, each of which can be bent around a central point, so as to realize flexible navigation of the endoscope in narrow or complex environments. The bending of the snake is usually achieved by traction of a high-strength wear-resistant steel wire rope or cable (the above is the conventional control method of the endoscope snake tube, not shown in the specification). The snake tube 35 is connected between the catheter 3 and the guide end piece 34 to achieve the effect of being able to flexibly adjust the curvature of the guide end piece 34, thereby achieving the purpose of flexibly controlling the optical lens 4 to collect images in the throat, and the purpose of flexibly removing secretions and foreign bodies in the throat by the clamping portion 62 of the negative pressure suction tube 7 and the foreign body forceps 6.

[0043] Ginseng Fig. 9 As shown in FIG. 1 , another embodiment of a visual throat foreign body treatment and suction auxiliary device disclosed by the present invention is different from the aforementioned embodiment in that: in this embodiment, the display device 5a is configured as a display connected to the laryngoscope handle 2, and the photoelectric component 41 and the lighting optical fiber 42 (see the aforementioned embodiment and the attached drawing for details) are arranged inside the laryngoscope handle 2. Figure 2 and attached Figure 6 ) is connected to the display device 5a. Specifically, in this embodiment, the display device 5a is connected to the display device 5a through the connecting component 5a1 (see Fig. 9 As shown in the figure, the optical fiber 41 and the illumination fiber 42 are connected to the upper edge of the laryngoscope handle 2. Figure 2 Middle connecting line 51, Fig. 9 The connecting wire passes through the connecting component 5a1 and is then connected to the display device 5a. Furthermore, a button device (not shown) for controlling the power on and off of the display device 5a and the optoelectronic component 41 may be provided at the connecting component 5a1.

[0044] It should be noted that in this embodiment, the display device 5a is connected to the upper edge of the outer side of the laryngoscope handle 2 by the connecting component 5a1, which makes the overall structure of the visual throat foreign body treatment and suction auxiliary device more compact compared to the previous embodiment. While having the advantages of simple structure and easy to carry, it still has the advantages of the visual throat foreign body treatment and suction auxiliary device in the previous embodiment, which is not affected by the stenosis of the pharynx and the poor exposure of the pharynx caused by the complex anatomical structure, and can achieve the purpose of accurate and rapid removal of foreign bodies in the throat, and can effectively remove secretions and food residues in the throat to ensure a clear field of vision and facilitate the accurate removal of foreign bodies in the throat. Since this embodiment has the advantages of simple structure and portability compared to the previous embodiment, it is more suitable for treatment places such as emergency departments that are not equipped with professional laryngoscope equipment.

[0045] When using the visualized throat foreign body treatment and suction auxiliary device described in this embodiment to treat throat foreign bodies, the gripping section 22 of the laryngoscope handle 2 is held so that the guide end piece 34 drives the catheter 3 as a whole to extend into the throat, and the display device 5a formed on the upper edge of the laryngoscope handle 2 displays the throat image captured by the optical lens 4 in real time, and then the secretions and food residues in the throat are sucked out by the negative pressure suction tube 7, and the foreign bodies stuck in the throat are removed by the foreign body forceps 6. The specific control method is consistent with the above-mentioned embodiment and will not be described in detail here. It should be noted that in this embodiment, the connecting component 5a1 is configured as a bendable tubular component (for example, metal material), and the bending direction of the connecting component 5a1 is changed during operation to observe the throat image displayed by the display device 5a.
