Description

Technical Field

[0001] The present application belongs to the field of medical teaching and training technology, and specifically relates to a bronchoscope simulation device. Background Art

[0002] Bronchoscopy is a commonly used operation technique in clinical practice, and it has very important clinical significance in the diagnosis and treatment of respiratory diseases. Bronchoscopes are suitable for observation of lesions in lobes, segments and subsegments of the bronchi, biopsy sampling, bacteriology and cytology examinations, and can be used for photography, teaching and dynamic recording with TV systems. Bronchoscopes can be used for testing, surgery, sampling, medication and other operations through matching accessories. Common bronchoscopes are divided into rigid bronchoscopes and flexible bronchoscopes. Flexible bronchoscopes are also called flexible bronchoscopes, which are divided into fiber bronchoscopes and electronic bronchoscopes.

[0003] Before the actual operation of the flexible bronchoscope, novice doctors need a lot of medical technology training and operation practice. This faces many problems, mainly: first, this kind of medical technology training or practice cannot be carried out directly on the human body, but can only be carried out through a simulation system; second, the use of real bronchoscope equipment has a high procurement cost, and when the novice doctors participating in the training have a weak foundation, it is easy to damage the equipment; third, the bronchoscope also requires other supporting equipment, such as medication tubes, irrigation tubes, foreign body forceps, etc., resulting in high operating and maintenance costs for bronchoscopes and supporting equipment.

[0004] There are some simulation devices in the prior art that can be used for simulation operation training of bronchoscopes, but the glottis of the larynx of these simulation devices is always in an open state, which is seriously inconsistent with the actual situation of the intermittent opening and closing of the human glottis, resulting in the operator feeling different from the actual clinical operation when performing bronchoscope operation training, and the simulation training effect is poor, which cannot meet the simulation training needs of clinical doctors. For example, Chinese patent CN217467868U provides a silicone lung model teaching tool for bronchoscopes. The glottis of this teaching tool is made of a thin and transparent material, and the glottis has a fissure for the bronchoscope to pass through. After the bronchoscope enters the nasal concha, an operable nasal concha passage is selected, and the mirror body stays in the throat for a while, and the mirror is inserted into the glottis fissure. Because the glottis of this teaching tool is provided with a fissure of fixed shape structure, the opening and closing action of the human glottis cannot be simulated during the operation training process, which is different from the situation where the bronchoscope is placed in the human glottis, and the simulation training effect is poor.

[0050] In this embodiment, the bronchoscope simulation device also includes an external microcontroller 400, which is connected to the glottis structure 201 via a wired connection or a wireless connection. The external microcontroller 400 is configured to control the glottis structure 201 to open and close according to a set program.

[0051] In one of the optional embodiments, the glottis structure 201 includes a support seat 1 and an opening and closing assembly arranged on the support seat 1; the support seat 1 is fixedly arranged inside the shell; the opening and closing assembly has a first splint 62, a second splint 72 and a driving mechanism, and the driving mechanism is configured to drive the first splint 62 and the second splint 72 to approach and move away from each other to achieve the opening and closing state adjustment of the glottis structure 201; when the first splint 62 and the second splint 72 are close to and in contact with each other, the glottis structure 201 is in a closed state; when the first splint 62 and the second splint 72 are away from each other, the glottis structure 201 is in an open state, and in the open state, there is an open gap between the first splint 62 and the second splint 72, and the open gap and the inlet 202 and the outlet of the shell are located on the moving path of the insertion end of the bronchoscope 300, and the moving path of the insertion end of the bronchoscope 300 is the same or similar to the moving path of the bronchoscope 300 in the internal channel of the human throat.

[0052] In one of the optional embodiments, the driving mechanism has a stepper motor 2, a transmission gear 21, a first rack 22, a second rack 23, a guide rail 13, a first slider 4 and a second slider 5; the first clamping plate 62 is connected to the guide rail 13 through the first slider 4, the second clamping plate 72 is connected to the guide rail 13 through the second slider 5, the first slider 4 is connected to the first rack 22, and the second slider 5 is connected to the second rack 23; the stepper motor 2 drives the first rack 22 and the second rack 23 to move in parallel and opposite directions through the transmission gear 21 to achieve the approach and distance of the first clamping plate 62 and the second clamping plate 72.

[0053] Exemplarily, a limit slot 11 is transversely provided at the top of the support seat 1, a guide rail 13 is transversely fixedly connected to the rear side of the top of the support seat 1 away from the limit slot 11, and a stepper motor 2 is fixedly connected to the bottom center of the support seat 1, the driving end of the stepper motor 2 movably passes through the support seat 1 and is fixedly connected to a transmission gear 21, a first rack 22 is meshed at the front side of the transmission gear 21, and a second rack 23 is meshed at the rear side of the transmission gear 21, and one end of the first rack 22 is fixed along its own length direction. A connecting rod 24 is connected, and a limiting rod 3 is fixedly connected at the bottom center of the first rack 22. The limiting rod 3 and the limiting groove 11 are adapted to each other, and the limiting rod 3 is slidably connected to the inside of the limiting groove 11. By sliding the limiting rod 3 left and right in the limiting groove 11, the running trajectory of the first rack 22 can be limited, which can prevent the first rack 22 from positionally shifting during the movement; one end of the connecting rod 24 is fixedly connected to the first slider 4, and one end of the second rack 23 is fixedly connected to the second slider 5.

[0054] In one of the optional embodiments, two rolling blocks 12 are also installed on the support seat 1. The two rolling blocks 12 are arranged on the support seat 1 through a rotating shaft and are configured to guide the insertion fiber tube 301 of the bronchoscope 300 to smoothly pass through the glottal structure 201; the axis of the rotating shaft is parallel to the axis of the transmission gear 21, the two rolling blocks 12 are located on the outside of the limiting groove 11, and the transmission gear 21 is located on the inner and outer sides of the limiting groove 11. The insertion fiber tube 301 of the bronchoscope 300 can pass through the space between the two rolling blocks 12, and when the insertion fiber tube 301 of the bronchoscope 300 is in friction contact with the rolling blocks 12, the rolling blocks 12 can rotate.

[0055] In one of the optional embodiments, the top of the first slider 4 is fixedly connected to a first pad 6, the top of the first pad 6 is fixedly connected to a first sensor 61, the top of the first sensor 61 is fixedly connected to a first clamping plate 62, the first clamping plate 62 is fixedly connected to a first electromagnet 63, the top of the second slider 5 is fixedly connected to a second pad 7, the top of the second pad 7 is fixedly connected to a second sensor 71, the top of the second sensor 71 is fixedly connected to a second clamping plate 72, and the second clamping plate 72 is fixedly connected to a second electromagnet 73.

[0056] like Figure 6 As shown, the output ends of the first sensor 61 and the second sensor 71 are both electrically connected to the input end of the external microcontroller 400, and the output end of the external microcontroller 400 is respectively electrically connected to the input ends of the stepper motor 2, the first electromagnet 63 and the second electromagnet 73. The first sensor 61 and the second sensor 71 are both pressure sensors.

[0057] In one of the optional embodiments, the first slider 4 and the second slider 5 are both slidably engaged on the top of the guide rail 13, and one end of the second rack 23 is fixedly connected to the front surface of the second slider 5. The sliding of the first slider 4 and the second slider 5 on the guide rail 13 can drive the first clamping plate 62 and the second clamping plate 72 to move relative and oppositely, which is convenient for the actual simulation operation of the external bronchoscope. Moreover, since the first slider 4 and the second slider 5 are both rectangular structures, they have a certain limiting effect and can prevent their own positions from being offset.

[0058] In one of the optional embodiments, the first rack 22 and the second rack 23 are relatively distributed, and the first rack 22 and the second rack 23 are both located above the limiting groove 11, and the lengths of the first rack 22 and the second rack 23 are equal. Through the forward and reverse rotation of the transmission gear 21, the first rack 22 and the second rack 23 can be driven to move relative and oppositely, thereby driving the first slider 4 and the second slider 5 to move relative and oppositely.

[0059] In one optional embodiment, the first clamping plate 62 and the second clamping plate 72 are relatively distributed, and the first clamping plate 62 and the second clamping plate 72 are both "L" shaped structures. The first pad 6 and the second pad 7 are both "T" shaped structures, and the first pad 6 and the second pad 7 are equal in size, which can increase the tightness between the first pad 6 and the first slider 4, and can also increase the tightness between the second pad 7 and the second slider 5.

[0060] In this embodiment, the connecting rod 24 is fixedly connected to the front surface of the first slider 4, which increases the stability of the connection between the stepper motor 2 and the first slider 4. The first electromagnet 63 and the second electromagnet 73 are relatively distributed, and the tops of the first clamping plate 62 and the second clamping plate 72 are located on the same horizontal line. After the first electromagnet 63 and the second electromagnet 73 are in contact, the first clamping plate 62 and the second clamping plate 72 can be tightly pressed together.

[0061] Taking into account the differences in sensitivity of patients of different age groups to bronchoscopes, the bronchoscope simulation device of this embodiment has a variety of setting programs to adapt to patients of different age groups. Exemplarily, the setting program includes a first-level setting program, a second-level setting program, and a third-level setting program. The first-level setting program is suitable for the elderly, with an opening and closing rate of 12 times / minute, and a spacing of 1 cm between the first splint 62 and the second splint 72 when they move in opposite directions; the second-level setting program is suitable for middle-aged people, with an opening and closing rate of 16 times / minute, and a spacing of 1.5 cm between the first splint 62 and the second splint 72 when they move in opposite directions; the third-level setting program is suitable for teenagers, with an opening and closing rate of 20 times / minute, and a spacing of 2 cm between the first splint 62 and the second splint 72 when they move in opposite directions. That is to say, the external microcontroller 400 is divided into three gears: the first gear, the second gear and the third gear, wherein the first gear setting program is suitable for the elderly, that is, the distance between the first splint 62 and the second splint 72 when they move in opposite directions is 1 cm, and the opening and closing rate of the microprocessor is 12 times per minute; the second gear setting program is suitable for middle-aged people, that is, the distance between the first splint 62 and the second splint 72 when they move in opposite directions is 1.5 cm, and the opening and closing rate of the microprocessor is 16 times per minute; the third gear setting program is suitable for teenagers, that is, the distance between the first splint 62 and the second splint 72 when they move in opposite directions is 2 cm, and the opening and closing rate of the microprocessor is 20 times per minute.

[0062] It should be noted that: in the first gear, when the first splint 62 and the second splint 72 move to 1 cm in opposite directions, the microcontroller controls the stepper motor 2 to work in reverse, and the intern doctor needs to pull out the bronchoscope from between the first splint 62 and the second splint 72 at this time; in the second gear, when the first splint 62 and the second splint 72 move to 1.5 cm in opposite directions, the microcontroller controls the stepper motor 2 to work in reverse, and the intern doctor needs to pull out the bronchoscope from between the first splint 62 and the second splint 72 at this time; in the third gear, when the first splint 62 and the second splint 72 move to 2 cm in opposite directions, the microcontroller controls the stepper motor 2 to work in reverse, and the intern doctor needs to pull out the bronchoscope from between the first splint 62 and the second splint 72 at this time.

[0063] In one optional embodiment, the external microcontroller 400 can be operated with one hand, and the external microcontroller 400 has a grip portion 401, and the grip portion 401 is provided with a display portion 402 and an operation button 403. Exemplarily, the display portion includes a plurality of indicator lights for displaying the switch state and the setting program working state; the number of the operation buttons is three, and the three operation buttons include functions such as turning on and off the power supply, switching the setting program, and regulating the opening and closing spacing and speed of the first splint 62 and the second splint 72 of the glottis structure 201; for example, when the grip portion 401 is held with one hand, the display portion is within the operator's field of vision, and an operation button 403 is provided in the pressing range of the index finger and the middle finger, and an operation button 403 is provided in the pressing range of the ring finger or the little finger.

[0064] The working principle and operation process of the bronchoscope simulation device are as follows:

[0065] When using the device, the bronchoscope is inserted through the nostrils of the model, and the device is placed at the throat of the model, and the microcontroller is installed on the outside of the model; when the subject to be tested is an elderly person, the program is switched to the first gear setting program to control the stepper motor 2 to rotate forward, at which time the first rack 22 and the second rack 23 can be driven to move relative to each other, and when the first rack 22 and the second rack 23 move relative to each other, the first slider 4 and the second slider 5 can be driven to move relative to each other, and then the first pad 6 and the second pad 7 can be driven to move relative to each other, and finally the first splint 62 and the second splint 72 can be driven to move relative to each other, and when the first splint 62 and the second splint 72 are in contact, the first electromagnet 63 and the second electromagnet 73 are attracted to each other, and when the upper bronchoscope abuts against the first electromagnet 63 When the first and second electromagnets 73 are on, the first and second electromagnets 63 and 73 can be compressed. At this time, the first sensor 61 and the second sensor 71 can receive corresponding pressure values. When the pressure values ​​reach the specific values ​​for the elderly on the microcontroller, the microcontroller controls the stepper motor 2 to reverse, which can drive the transmission gear 21 to reverse. After the transmission gear 21 reverses, it can drive the first rack 22 and the second rack 23 to move in opposite directions. When the first rack 22 and the second rack 23 move in opposite directions, it can drive the first slider 4 and the second slider 5 to move in opposite directions, and then drive the first pad 6 and the second pad 7 to move in opposite directions. Finally, it can drive the first splint 62 and the second splint 72 to move in opposite directions until the first splint 62 and the second splint 72 move in opposite directions. It only needs to be moved to 1 cm. At this time, it is convenient for the upper bronchoscope to pass between the first splint 62 and the second splint 72, which is convenient for subsequent operations. When the object to be tested is a middle-aged person, the stepper motor 2 is controlled to rotate forward and switched to the second gear setting program. At this time, the first rack 22 and the second rack 23 can be driven to move relative to each other. When the first rack 22 and the second rack 23 move relative to each other, the first slider 4 and the second slider 5 can be driven to move relative to each other, and then the first pad 6 and the second pad 7 can be driven to move relative to each other. Finally, the first splint 62 and the second splint 72 can be driven to move relative to each other. When the first splint 62 and the second splint 72 are in contact, the first electromagnet 63 and the second electromagnet 73 are attracted to each other. When the upper bronchoscope is against the first electromagnet 63 and the second electromagnet When the iron 73 is on, the first electromagnet 63 and the second electromagnet 73 can be compressed. At this time, the first sensor 61 and the second sensor 71 can receive the corresponding pressure value.
