Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to a foreign body removal device for the ear, nose and throat. Background Technology

[0002] Otolaryngology departments often face the problem of foreign bodies lodged in the nasal cavity, pharynx, and ear canal. Foreign body removal instruments are commonly used tools in the department. They can accurately grasp, clamp, or hook different types of foreign bodies (such as solid particles and soft foreign bodies) and their lodged locations, quickly and safely removing foreign bodies without damaging surrounding tissues. They are key instruments for ensuring the safety of diagnosis and treatment.

[0003] Fish bones stuck in the throat are a common emergency in otolaryngology, which can easily cause discomfort and risks. It is necessary to use targeted foreign body removal instruments to remove them accurately and safely. The main body of the foreign body removal instrument is a special forceps with a near 90° bending structure at the tip, which is adapted to the narrow space of the throat and the angle of foreign body retention. It can accurately reach the lesion and firmly grasp foreign bodies such as fish bones. It is convenient to operate and can reduce tissue damage. For example, a foreign body removal forceps for the throat disclosed in patent publication number CN119279696B. However, in actual use, this type of foreign body removal device still has certain defects. Taking the removal of a fishbone as an example, when the instrument is pulled out after gripping the fishbone, the resistance of the throat tissue to the fishbone disappears instantly. At this time, the handheld instrument may be displaced due to inertia because the resistance has disappeared, which may cause the fishbone or the instrument to hit the throat a second time, increasing the risk of secondary injury. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a foreign body removal device for the ear, nose, and throat.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an ear, nose, and throat foreign body removal device, comprising a base and a clamp assembly disposed above the base, and further comprising: A frame block is fitted onto the outside of the clamp body assembly, and a pin rod that is hinged to the clamp body assembly is fixed inside the frame block; A mounting base is disposed between the frame block and the base, and the base is equipped with a height adjustment component for adjusting the height of the mounting base. Two track side plates are disposed on both sides above the mounting base, and the mounting base is equipped with a resistance unit connected to the track side plates; The speed detection unit is installed inside the track side plate and is used to detect the moving speed of the frame block. The base is equipped with a control board, and the control board controls the resistance unit to work according to the electrical signal fed back by the speed detection unit. An adsorption and fixing unit is connected to the base.

[0006] Preferably, the height adjustment assembly includes an internally threaded cylinder fixed to the upper surface of the base, and an adjusting screw is threadedly connected to the inner side wall of the internally threaded cylinder. The adjusting screw is equipped with a universal adjustment assembly, and the adjusting screw is connected to the mounting base through the universal adjustment assembly.

[0007] Preferably, the universal adjustment assembly includes a support ball fixed to the top of the adjustment screw, the upper surface of the mounting base is integrally formed with a protrusion, and the protrusion has a ball groove that penetrates the bottom of the mounting base. The support ball is rotatably connected to the mounting base through the ball groove.

[0008] Preferably, the resistance unit includes a T-shaped seat fixed on both sides of the upper surface of the mounting base, and the T-shaped seat is slidably disposed inside the track side plate on the same side. A non-magnetic spring is fixed between the side wall of the T-shaped seat and the inner side wall of the track side plate. An iron block is fixed to the inner side wall of the track side plate, and an electromagnetic component corresponding to the position of the iron block is fixed to the end of the T-shaped seat.

[0009] Preferably, the speed detection unit includes rotating columns arranged vertically inside the track side plate, and the rotating columns are rotatably connected to the track side plate. Two adjacent rotating columns mesh with each other. A T-shaped slider is fixed to the side wall of the frame block, and the end of the T-shaped slider contacts the side wall of the rotating column. An encoder is fixed to the side wall of both track side plates, and the detection end of the encoder is drivenly connected to the rotation end of the corresponding rotating column. The control board controls the corresponding electromagnetic components to work according to the electrical signal fed back by the encoder.

[0010] Preferably, the adsorption fixing unit includes an adsorption plate fixed to the bottom of the base, and multiple suction cups are fixedly inserted into the adsorption plate. The bottom of the base has a groove that communicates with the suction cups. The groove wall is fixedly connected to an air suction pipe, and the air outlet end of the air suction pipe is fixedly connected to a hand-squeezable airbag. An exhaust assembly is installed at the air outlet end of the hand-squeezable airbag, and a one-way valve is installed inside the exhaust assembly and inside the air suction pipe. The exhaust assembly is connected to a toothed mechanism.

[0011] Preferably, the exhaust assembly includes a three-way pipe that is fixedly connected to the hand-squeezed airbag. One outlet end of the three-way pipe is threadedly connected to a sealing cap. Two one-way valves are provided inside the three-way pipe and are located at the two outlet ends respectively. The outlet end of the three-way pipe away from the sealing cap is connected to an exhaust hose.

[0012] Preferably, the tooth pad mechanism includes an upper U-shaped tooth pad and a lower U-shaped tooth pad sleeved on the outside of the exhaust hose outlet end, with the upper U-shaped tooth pad sliding vertically inside the lower U-shaped tooth pad.

A hollow block is fixedly connected to the exhaust end of the three-way pipe on the side away from the sealing cap, and a pressure detector is fixed inside the hollow block. The support airbag is connected to the inside of the hollow block through the exhaust hose.

[0013] Compared with existing technologies, the advantages of a foreign body removal device for the ear, nose, and throat are: 1. Through the coordinated operation of the base, clamp assembly, frame block, and pin, foreign objects such as fish bones can be removed from the patient's throat by gripping. Through the coordinated operation of the mounting base, track side plate, resistance unit, speed detection unit, and control board, the resistance to the displacement of the clamp assembly can be automatically adjusted based on the speed at which the doctor moves the clamp assembly. This can minimize the risk of secondary injury caused by the clamp assembly impacting the patient's throat due to inertia when the foreign object leaves the throat, as the resistance between the foreign object and the throat disappears.

[0014] 2. With the height adjustment component and the universal adjustment component, different support heights can be adjusted to suit different patients. The universal adjustment component can also ensure that medical staff can drive the forceps component to tilt and change angles, thus improving its applicability.

[0015] 3. The adsorption and fixation unit can be used to easily fix the entire device, preventing instability that could cause secondary injury to the patient and improving the safety of the foreign body removal process.

[0016] 4. The air venting assembly and dental pad mechanism can support and open the patient's upper and lower teeth when removing foreign objects, thus keeping the patient's mouth in a stable open state and minimizing the risk of secondary injury caused by the patient's mouth suddenly closing during foreign object removal, thereby further improving the safety of the foreign object removal process.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] like Figures 1-7 As shown, an ear, nose, and throat foreign body removal device includes a base 1 and a forceps assembly 2 disposed above the base 1. It also includes a frame block 3, which is sleeved on the outside of the forceps assembly 2. A pin 4, hinged to the forceps assembly 2, is fixed inside the frame block 3. The forceps assembly 2 includes two handles, two main rods, and two curved forceps heads. The forceps heads are connected to the main rods by studs. The angle of the forceps heads can be adjusted appropriately according to the position of the foreign body lodged in the patient's ear, thereby increasing the foreign body grasping range. A mounting base 5 is disposed between the frame block 3 and the base 1. The base 1 is equipped with a height adjustment assembly 6 for adjusting the height of the mounting base 5. The height adjustment assembly 6 includes an internally threaded cylinder 61 fixed to the upper surface of the base 1, and an adjusting screw 62 is threadedly connected to the inner wall of the internally threaded cylinder 61. The adjusting screw 62 is equipped with a universal adjustment assembly 63, and the adjusting screw 62 is adjusted via a universal joint. The joint component 63 is connected to the mounting base 5. The universal adjustment component 63 includes a support ball 631 fixed to the top of the adjustment screw 62. The upper surface of the mounting base 5 is integrally formed with a protrusion 632, and the protrusion 632 has a ball groove that runs through the bottom of the mounting base 5. The support ball 631 is rotatably connected to the mounting base 5 through the ball groove. The support ball 631 is wrapped with a rubber damping pad to prevent the support ball 631 from rotating freely between itself and the ball groove. The power supply and signal feedback between the control board 10, the speed detection unit 9, and the resistance unit 8 are connected by a plug and socket. When the base 1 is rotated, the plug and socket are separated to prevent the cable from affecting the normal rotation of the base 1. Furthermore, the mounting base 5, frame block 3, track side plate 7, support ball 631, T-shaped seat 81, etc. are all made of medical lightweight plastic to reduce weight, make them easy to handle, and improve portability.

[0021] Two track side plates 7 are set on both sides above the mounting base 5. The mounting base 5 is equipped with a resistance unit 8 connected to the track side plate 7. The resistance unit 8 includes a T-shaped seat 81 fixed on both sides of the upper surface of the mounting base 5. The T-shaped seat 81 is slidably disposed inside the track side plate 7 on the same side. A non-magnetic spring 82 is fixed between the side wall of the T-shaped seat 81 and the inner side wall of the track side plate 7. An iron block 83 is fixed to the inner side wall of the track side plate 7. An electromagnetic component 84 corresponding to the position of the iron block 83 is fixed to the end of the T-shaped seat 81. When the electromagnetic component 84 is energized, it will generate a magnetic attraction force on the iron block 83.

[0022] The speed detection unit 9 is installed inside the track side plate 7 and is used to detect the moving speed of the frame block 3. A control board 10 is installed on the base 1, and the control board 10 controls the resistance unit 8 to operate based on the electrical signal fed back by the speed detection unit 9. The speed detection unit 9 includes vertically arranged rotating columns 91 inside the track side plate 7, and the rotating columns 91 are rotatably connected to the track side plate 7. Adjacent rotating columns 91 mesh with each other. A T-shaped slider 92 is fixed to the side wall of the frame block 3, and the end of the T-shaped slider 92 contacts the side wall of the rotating column 91. Encoders 9 are fixed to the side walls of both track side plates 7. 3. The detection end of the encoder 93 is connected to the rotating end of the corresponding rotating column 91. The control board 10 controls the corresponding electromagnetic component 84 to work according to the electrical signal fed back by the encoder 93. When the rotating column 91 rotates, it will drive the code disk inside the encoder 93 to rotate synchronously. The code disk alternately blocks the light path to generate pulse signals. The control board 10 calculates the rotation speed of the rotating column 91 by collecting the pulse frequency. At the same time, the T-shaped slider 92 will only contact one rotating column 91 at most. And because the side rails 7 on both sides apply clamping force to the frame block 3, the T-shaped slider 92 will drive the corresponding rotating column 91 to rotate as the frame block 3 moves.

[0023] The adsorption fixing unit 11 is connected to the base 1. The adsorption fixing unit 11 includes an adsorption plate 111 fixed to the bottom of the base 1, and multiple suction cups 112 are fixedly inserted into the adsorption plate 111. The bottom of the base 1 is provided with a groove 113 that communicates with the suction cups 112. The groove wall of the groove 113 is fixedly connected to an air suction pipe 114, and the air outlet of the air suction pipe 114 is fixedly connected to a hand-squeezed air bag 115. When the suction cup 112 is in close contact with the table and the air inside it is drawn away, the suction cup 112 will be stably adsorbed on the table due to the pressure difference between the inside and outside.

[0024] An exhaust assembly 12 is installed at the air outlet of the hand-held airbag 115, and a one-way valve 116 is installed inside both the exhaust assembly 12 and the air intake pipe 114. The exhaust assembly 12 includes a three-way pipe 121 that is fixedly connected to the hand-held airbag 115. A sealing cap 122 is threadedly connected to one air outlet of the three-way pipe 121. Two one-way valves 116 are provided inside the three-way pipe 121 and are located at the two air outlets respectively. An exhaust hose 123 is connected to the air outlet on the side of the three-way pipe 121 away from the sealing cap 122. The function of the sealing cap 122 is to prevent air from leaking out when inflating the support airbag 133.

[0025] The exhaust assembly 12 is connected to a toothed mechanism 13, which includes an upper U-shaped toothed pad 131 and a lower U-shaped toothed pad 132 fitted on the outside of the exhaust hose 123 outlet end. The upper U-shaped toothed pad 131 slides vertically inside the lower U-shaped toothed pad 132. A support airbag 133 is fixed between the upper U-shaped toothed pad 131 and the lower U-shaped toothed pad 132. The outlet end of the three-way pipe 121 away from the sealing cap 122 is fixedly connected to a hollow block 134, and a pressure detector 135 is fixed inside the hollow block 134. The support airbag 133 is connected to the inside of the hollow block 134 through the exhaust hose 123, and the pressure detector 135 can detect the pressure inside the hollow block 134. The pressure is converted into a numerical value and displayed. The side wall of the hollow block 134 has an exhaust hole with a plug connected to the threaded hole for easy venting. The upper U-shaped dental pad 131 and the lower U-shaped dental pad 132 can be covered with a disposable bag made of medical material during use to avoid direct contact between the upper U-shaped dental pad 131 and the lower U-shaped dental pad 132 and the patient. This can avoid cross-infection and increase the friction between the upper U-shaped dental pad 131 and the lower U-shaped dental pad 132 and the teeth to ensure stable occlusion. At the same time, the supporting airbag 133, the exhaust hose 123, the hand-squeezed airbag 115, etc. are all made of medical high-temperature resistant materials to ensure suitability for high-temperature sterilization environments.

[0026] The operating principle of this invention is explained as follows: The patient is seated with their head tilted back about 30° (for children or other patients with poor self-control, a head fixation device needs to be added to the head position for head fixation, or medical staff can assist in head fixation to ensure that the head does not deflect during the removal of the foreign object). Then, the medical staff takes out the sterilized device and rotates the base 1 according to the patient's head position. The base 1 will drive the internal threaded cylinder 61 to rotate, thereby increasing the distance between the base 1 and the mounting base 5. Finally, when the base 1 is placed on the table, the frame block 3 is slightly higher than the patient's head. Then, the medical staff placed the upper U-shaped mouthguard 131 and the lower U-shaped mouthguard 132 on one side of the patient's mouth, with the upper U-shaped mouthguard 131 and the lower U-shaped mouthguard 132 positioned between the patient's upper and lower teeth. The medical staff then squeezed the hand-operated airbag 115. When the hand-operated airbag 115 was squeezed, under the action of the one-way valve 116, the air inside the hand-operated airbag 115 entered the hollow block 134 through the three-way tube 121, and then entered the support airbag 133 through the exhaust hose 123. When the hand-operated airbag 115 was released, under the action of the one-way valve 116, external air was replenished into the hand-operated airbag 115 through the suction tube 114. By continuously squeezing the hand-operated airbag 115, air can be supplied to the support airbag 133. Under the action of the increasing air, the support airbag 133... The air bladder 133 inflates, increasing the distance between the upper U-shaped dental pad 131 and the lower U-shaped dental pad 132, thus supporting and opening the patient's mouth. During this process, medical staff should instruct the patient to keep their mouth relaxed. When the mouth is fully open, the travel of the upper U-shaped dental pad 131 and the lower U-shaped dental pad 132 is obstructed, and the support air bladder 133 cannot continue to inflate. Therefore, the air pressure inside the hollow block 134 will rise rapidly. Medical staff can stop squeezing the hand-operated air bladder 115 once the air pressure displayed on the air pressure detector 135 reaches the threshold (this threshold is set based on different patients; for example, the air pressure threshold for the elderly and children can be set in the range of 3.0-7.0 kPa, while the corresponding air pressure threshold for adults can be set in the range of 6.0-10.0 kPa). The medical staff then unscrewed the sealing cap 122 of the three-way tube 121 and ensured that the adsorption plate 111 was in close contact with the table. They then continued to squeeze the hand-squeezing airbag 115. At this time, because the air pressure inside the supporting airbag 133 was higher than the external atmospheric pressure, the air expelled by squeezing the airbag 115 would be expelled through the air outlet on the side of the three-way tube 121 away from the hollow block 134. By continuously squeezing the hand-squeezing airbag 115, the air inside the groove 113 of the base 1 and inside each suction cup 112 was continuously reduced. Under the action of the internal and external pressure difference, each suction cup 112 was stably adsorbed on the table, thus ensuring that the base 1 was installed stably enough and would not tip over. After the adsorption plate 111 is stably adsorbed onto the table, the medical staff stops squeezing the hand-operated airbag 115 and holds the two handles of the forceps assembly 2 with one hand, keeping the two clamping ends of the forceps assembly 2 closed. The forceps assembly 2 is then inserted into the patient's throat through the mouth. The other hand can use a light source or a miniature camera to observe the location of the foreign object in the patient's throat. When the foreign object is located, the clamping ends of the forceps assembly 2 are slightly opened and the object is firmly grasped. The forceps assembly 2 is then slowly moved, and the foreign object is pulled outwards using it. During this process, because the forceps assembly 2 needs to be inserted into the patient's throat, the overall height of the forceps assembly 2 decreases during insertion. When the foreign object is clamped outward, the overall height of the clamp assembly 2 increases. This height displacement of the clamp assembly 2 drives the frame block 3 to move up and down between the two track side plates 7. As the frame block 3 moves, the T-shaped slider 92 contacts the rotating column 91, causing the frame block 3 to rotate through the T-shaped slider 92. Since two adjacent rotating columns 91 on the same side are interlocked, one rotating column 91 will drive the other rotating columns 91 to rotate. The rotation of the rotating columns 91 synchronously drives the detection end of the encoder 93 to rotate. The encoder 93 then detects the rotation speed of the rotating columns 91 in real time. The rotation of the rotating columns 91 synchronously drives the code disk inside the encoder 93 to rotate, and the code disk alternately blocks the light path. A pulse signal is generated, and the control board 10 calculates the rotational speed of the rotating column 91 by collecting the pulse frequency. The higher the rotational speed of the rotating column 91, the faster the medical staff moves the clamp assembly 2. At this time, the control board 10 controls the current intensity of the electromagnetic component 84 on the same side to be greater. The electromagnetic component 84 generates a magnetic attraction force on the iron block 83 on the same side. The greater the current intensity, the greater the magnetic attraction force generated by the electromagnetic component 84 on the iron block 83. At this time, the clamping pressure applied by the side rail plates 7 on the frame block 3 through the T-shaped slider 92 is greater, which will increase the frictional resistance between the frame block 3 and the two side rail plates 7. By increasing the frictional resistance, the moving speed of the frame block 3 can be slowed down, thereby avoiding as much as possible. To prevent secondary impacts between the tip of the forceps assembly 2 and the patient's throat due to inertia when the foreign object is removed from the throat, thus reducing the risk of secondary injury and improving the safety of the foreign object removal process. Similarly, since the forceps assembly 2 needs to be moved by medical staff, due to the deviation of hand control stability, the forceps assembly 2 may not only move too fast during the removal of the foreign object, but may also move too fast when inserted into the patient's throat. Through the above-mentioned electromagnetic component 84 and other structures, the displacement resistance can be automatically adjusted based on the displacement speed of the forceps assembly 2, thereby ensuring that the entire forceps assembly 2 remains in a slow and low-speed state during the movement, ensuring the safety of use. After the foreign object is removed, the air inside the support airbag 133 is released (the side wall of the hollow block 134 has an air vent, and the hole is threaded with a plug to facilitate air release). Then, the upper U-shaped dental pad 131 and the lower U-shaped dental pad 132 are removed from the patient's mouth. Then, air is added to the groove 113 to restore it to normal pressure (the groove wall of the groove 113 has an air inlet, and the hole is threaded with a plug to facilitate the entry of external air into the groove 113). After that, the entire device is disinfected and stored.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
