Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically, to an electronic bronchoscope for pediatric respiratory department. Background Art

[0002] An electronic bronchoscope is a medical instrument used for internal examination of the trachea and bronchi. It is also commonly used in pediatric respiratory medicine. Due to the particularity of pediatrics (children are active), its working time is best controlled to a minimum. The front end of the electronic bronchoscope is a set of slender hoses with built-in objective lenses (ultra-small cameras), nozzles (supplying water and air), and light guides (illumination). It performs examinations or other treatments when it penetrates deep into the patient's bronchi. In the prior art, the surface of the insertion portion of the electronic bronchoscope is made of flexible materials such as silicone or rubber. After the front end penetrates deep into the patient's body, the distance between the operating end and the front end becomes longer and longer. After the front end enters the patient's body, when it needs to turn and face the symptom area, the shortcomings of the flexible material become apparent. The turning action of the operating end produces a slight deformation on the surface of the slender insertion portion, and this deformation becomes very large due to the length of the pipe. The direct consequence is that the steering is not sensitive and the operation time is long, which leads to increased pain for the patient. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 6 As shown, the utility model provides an electronic bronchoscope for pediatric respiratory department, including a fixed tube 1, a hose 2 is fixedly sleeved inside the fixed tube 1, an air inlet pipe 3, a light guide 4 and an objective lens 5 are installed inside the hose 2, a sleeve 7 is fixedly sleeved on the front end of the outer surface of the hose 2, an outer surface of the sleeve 7 is provided with an opening 14 and an opening 2 17 distributed at equal angles, the sleeve 7 is hollow inside, a sealing sleeve 15 is fixedly connected inside the opening 14, an abutment block 16 is fixedly connected to the inner wall of the sealing sleeve 15, a sealing sleeve 2 18 is fixedly connected inside the opening 2 17, an abutment block 2 19 is fixedly connected to the inner wall of the sealing sleeve 2 18, a connecting pipe 1 8 and a connecting pipe 2 9 are fixedly connected to the rear end of the sleeve 7, and the other ends of the connecting pipe 1 8 and the connecting pipe 2 9 are fixedly connected to an airbag 1 11 and an airbag 2 12 respectively.

[0022] The device is provided with a sleeve 7 and a sealing sleeve 15, abutment block 16, a sealing sleeve 2 18 and abutment block 2 19 inside the sleeve 7. Under the action of air pressure, the sealing sleeve 1 moves out from the inside of the sleeve 7 and abuts against the patient's body, thereby pushing the sleeve 7 and the hose 2 to move and realize steering. The airbag 1 11 and the airbag 2 12 are provided to respectively control the air intake of the two chambers inside the sleeve 7, and control the degree of eversion of the abutment block 16 and the opening 2 17, so that the abutment block 16 and the opening 2 17 abut against the patient's body during the eversion movement, and realize reverse thrust on the sleeve 7 and the hose 2. Since the inner cavity of the sleeve 7 is sealed, the air is pressed and supplied by the airbags 1 11 and 12, so that the precise steering function of the front end of the hose 2 can be realized.

[0023] Among them, the front end of the hose 2 is fixedly connected to a fixing block 6, the air intake pipe 3, the light guide 4 and the objective lens 5 are passed through and fixed therein at equal angles, and the inner wall of the fixed tube 1 is fixedly connected to a controller 20, which is electrically connected to the light guide 4 and the objective lens 5 respectively.

[0024] The light guide 4 is used to provide lighting, and the objective lens 5 is responsible for taking pictures of wherever it goes, and transmitting the pictures through the controller 20 and projecting them onto a large screen to facilitate operation by medical staff.

[0025] Among them, the middle and lower part of the outer surface of the fixed tube 1 is fixedly sleeved with a limiting ring 10, and airbag 1 11 and airbag 2 12 are fixedly installed on the opposite side of the outer surface of the fixed tube 1, airbag 1 11 is connected to connecting pipe 1 8, and airbag 2 12 is connected to connecting pipe 2 9.

[0026] The limiting ring 10 is used to fix and support airbag 1 11 and airbag 2 12. By arranging airbag 1 11 and airbag 2 12 at the holding position on the outer surface of the fixed tube 1, medical staff can grasp the pressing status of airbag 1 11 and airbag 2 12 at any time and accurately control the amount of air passing through connecting tube 1 8 and connecting tube 2 9. The annular design of the limiting ring 10 can enable it to be limitedly engaged near the middle finger of the medical staff and form an effective limiting support to maintain the stability of the device when in use.

[0027] Among them, two groups of symmetrically distributed isolation plates 13 are fixedly installed in the inner cavity of the sleeve 7, and the two groups of isolation plates 13 divide the inner cavity of the sleeve 7 into two independent chambers. The connecting pipe 1 8 is connected to the first chamber provided with a sealing sleeve 15, and the connecting pipe 2 9 is connected to the second chamber.

[0028] The isolation plate 13 can separate the interior of the sleeve 7 into a first chamber and a second chamber that are sealed and independent from each other, so that the pressing and exhausting states between the airbag 1 11 and the airbag 2 12 can be independent of each other and will not interfere with each other.

[0029] The opening directions of the first opening 14 and the second opening 17 are respectively the horizontal left tangent line and the horizontal right tangent line of the sleeve 7 .

[0030] like Figure 3 As shown, the openings of opening 14 and opening 2 17 can just guide the sealing sleeve 15, the abutment block 16, the sealing sleeve 2 18 and the abutment block 2 19 to horizontally flip out of the interior of the sleeve 7, and obtain reverse thrust under the tangential guiding effect, thereby realizing the turning of the hose 2.

[0031] The sealing sleeve 1 15 and the sealing sleeve 2 18 are both made of rubber blocks, and the abutment block 1 16 and the abutment block 2 19 are both made of silicone.

[0032] When the sealing sleeve 15 and the sealing sleeve 2 18 enter the patient's body, they will come into direct contact with the inner wall of the bronchus, and their flexible design can reduce damage to the patient's body.

[0033] The working principle of this utility model:

[0034] When the device is working, the front end of the hose 2 passes through the patient's mouth and nasal cavity and enters the trachea. The controller 20 controls the light guide 4 to illuminate, the objective lens 5 is turned on and takes pictures of where it goes, and projects them outside the large screen in real time. As the front end of the hose 2 gradually goes deeper, the distance between the sleeve 7 and the outside world becomes longer and longer. The air inlet pipe 3 can be connected to an external ventilator to supply air or water. After the front end of the hose 2 goes deep into the patient's body, when the direction needs to be adjusted;

[0035] Clockwise steering: Press the airbag 11, and let the air enter the first chamber through the connecting pipe 8, and push the sealing sleeve 15 and the abutment block 16 outward, so that the abutment block 16 turns out along the opening 14 and abuts against the inside of the patient, driving the sleeve 7 and the air inlet pipe 3 to rotate clockwise, or realize the left and right steering function;

[0036] Counterclockwise steering: Press the airbag 12, and let the air enter the second chamber through the connecting pipe 9, and push the sealing sleeve 18 and the abutment block 19 outward, so that the abutment block 19 turns out along the opening 17 and abuts against the inside of the patient, driving the sleeve 7 and the air inlet pipe 3 to rotate counterclockwise, or realize the left and right steering function;

[0037] By controlling the force of pressing the airbag 1 11 and the airbag 2 12 , the amount of air pressure pumped downward by the airbag 1 11 and the airbag 2 12 is controlled, thereby achieving a precise steering adjustment function of the front end portion of the hose 2 .
