Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an infection-preventing indirect bronchoscopy operating device. Background Technology

[0002] Bronchoscopy is a common examination method for the respiratory system. It is mainly used to examine the condition inside the airway or the reaction of lesions outside the airway in the airway. The bronchoscope is inserted through the mouth or nose into the patient's lower respiratory tract for observation, and specimens are collected from the lesion area for analysis.

[0003] During bronchoscopy brushing and biopsy, the inserted portion in the trachea or bronchus may encounter sputum and secretions that affect the extension of the trachea and require suctioning. However, during suctioning, the sputum and secretions are drawn out through the operating tube, and the biopsy forceps and brush also need to be transported through the operating tube afterward. This process can cause contaminants in the operating tube to be carried to other parts of the lower respiratory tract, increasing the risk of infection. At the same time, during bronchoscopy, especially during biopsy, bleeding and coughing can cause a sharp increase in tracheal pressure, causing blood and sputum to flow backward into the air and water delivery biopsy tube, leading to blockage and requiring additional cleaning. This process also increases the risk of infection for the patient.

[0004] Therefore, it is necessary to provide an infection-resistant indirect bronchoscopy device to solve the problems mentioned in the background art. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: an infection-preventing indirect bronchoscopy operating device, comprising: An operating frame is provided with an operating port and a suction port, and the operating port and the suction port are connected to the operating tube; An insertion assembly is fixedly connected to the lower end of the operating frame, and the insertion assembly includes an operating tube and a delivery tube; The control valve assembly is fixed on the operating frame, and the control valve assembly includes a suction valve, a water valve, an air valve, and multiple auxiliary adjustment buttons; The directional knob is rotatably mounted on the operating frame; The connector is fixedly connected to the operating frame.

[0006] Furthermore, preferably, the insertion component further includes: The sleeve has one end fixed to the operating frame and the other end fitted with an end cap. The snake bone assembly is fitted and fixed inside the sleeve, and the snake bone assembly is disposed close to the end cap; An adjustment component is disposed within the snake-bone assembly; A light guide and an objective lens are fitted inside the sleeve and snake bone assembly.

[0007] Furthermore, as a preferred embodiment, one end of the light guide and the objective lens are fixed to the end cap, and the other end is connected to an external light source and an image processor via the operating frame and connector. A micro motor connected to the auxiliary adjustment button is provided in the operating frame, and the micro motor can adjust the insertion component.

[0008] Furthermore, preferably, the snake bone assembly includes: Multiple snake-bone rings are configured and connected sequentially by hinges. Multiple curved steel wires are provided to connect the snake-bone ring and the direction adjustment knob.

[0009] Furthermore, preferably, the adjustment component includes: A pressure pipe is disposed between the delivery pipe and the operating pipe, and connects the delivery pipe and the operating pipe; Multiple support rings are provided, each corresponding to a single snake-bone ring; Two control wires are arranged, which are respectively sleeved on the operating tube and the conveying tube. The control wires pass through the support ring and are connected to the micro motor. The auxiliary adjustment button controls the contraction and relaxation of the control wires.

[0010] Furthermore, as a preferred embodiment, the pressure pipe has a built-in pressure valve and a check valve, which only allow communication from the delivery pipe to the operating pipe, and the opening pressure of the pressure valve is greater than the maximum adjustable suction pressure of the suction valve.

[0011] Furthermore, as a preferred embodiment, the support ring has an opening on one side that allows the control wire to pass through. The support ring near the end cap is used to adjust the conveying pipe, and the subsequent support ring is used to adjust the operating pipe. The openings of the two support rings face opposite directions.

[0012] Furthermore, as a preferred embodiment, the outer wall and inner wall of the operating tube are respectively provided with an outer support curved platform and an inner closed curved platform. The outer support curved platform and the inner closed curved platform on one side of the operating tube form an adjustment group. The two adjustment groups are staggered along the axial direction of the operating tube. The adjustment group on the side closer to the conveying tube is closer to the end cap, and the edge of this adjustment group is the control wire sleeve position, corresponding to the tension point of the operating tube. The other adjustment group is close to the support ring, and the corresponding outer support curved platform abuts against the support ring. This position is the limiting point of the operating tube.

[0013] Furthermore, as a preferred embodiment, the conveying pipe is fitted with a compression sleeve, one end of which abuts against the support ring. The side wall of the compression sleeve has a groove for placing a control wire, and the compression sleeve is fitted with a deflection radius on the end face of the support ring.

[0014] Compared with the prior art, the present invention provides an infection-preventing indirect bronchoscopy operation device, which has the following beneficial effects: 1. In this invention, if an aspiration operation is performed through the operating tube before conveying the brush and biopsy forceps, keeping the insertion assembly inside the body, pressing the auxiliary adjustment button causes the two control wires to retract, closing the operating tube and the delivery tube. First, press the suction valve to create negative pressure in the operating tube, then press the water valve to deliver cleaning fluid into the delivery tube to increase the pressure in the delivery tube. A pressure difference is created between the operating tube and the delivery tube, causing the pressure tube to open. The cleaning fluid enters the operating tube and is discharged from the suction port to clean the inner wall of the operating tube. After cleaning, the brush or biopsy forceps are inserted, which can effectively prevent infection. 2. In this invention, when the tracheal pressure rises sharply, the delivery tube can be closed to prevent blood and sputum from flowing back in and causing blockage and contamination. While blockage of the delivery tube usually involves removing the valve, rinsing it with sterile saline, and then replacing it, blockage of the operating tube is addressed by rinsing with 5-10 ml of saline, intermittently pressing the suction valve to aspirate secretions and blood, or using biopsy forceps to clear blood clots into the body before removal. This entire process is cumbersome and increases the risk of infection. Directly cleaning the operating and delivery tubes, creating a circulation, and cleaning both simultaneously, reduces the processing steps and indirectly decreases the risk of infection.

[0016] Please see Figure 1-5 In this embodiment of the invention, an infection-preventing indirect bronchoscopy operation device includes: The operating frame 1 has an operating port 3 and a suction port 5, and the operating port 3 and the suction port 5 are connected to the operating tube 25. Specifically, the operating port 3 is used to insert biopsy forceps and a brush to facilitate biopsy and brushing, and the suction port 5 is used to receive a collection container to collect secretions and other substances aspirated from the trachea. Insertion component 2 is fixedly connected to the lower end of the operating frame 1, and the insertion component 2 includes an operating tube 25 and a delivery tube 26. Specifically, the operating tube 25 is used to aspirate secretions in the trachea, and at the same time provides a channel for biopsy forceps and brush to enter the trachea. The control valve assembly 4 is fixed on the operating frame 1, and the control valve assembly 4 includes a suction valve, a water valve, an air valve, and multiple auxiliary adjustment buttons. Specifically, the suction valve is connected to an air pump. By controlling the air pump to work, a negative pressure is formed in the operating tube 25 to suction secretions in the trachea. The water valve and the air valve are connected to the air pump and the water pump. By controlling the air pump and the water pump, water and air are delivered through the delivery tube 26. The directional knob 6 is rotatably mounted on the operating frame 1; Connector 7 is fixedly connected to the operating frame 1.

[0017] It should be explained that during bronchoscopy, the insertion component 2 is first gently inserted through the nostril or mouth to observe for any abnormalities in the nasal cavity or pharynx. The insertion component 2 is then inserted gradually, avoiding contact with the bronchial walls. The main bronchi on both sides are observed, and each lobe bronchus is examined sequentially from top to bottom. If secretions are encountered that affect the delivery of the insertion component 2, the suction valve can be pressed to aspirate the secretions through the operating tube 25. Once the lesion is reached, the specimen can be collected, including suction (specifically, by pressing the suction valve through the operating tube 25 to aspirate secretions from the lesion area for storage), irrigation (by pressing the water valve through the delivery tube 26 to deliver irrigation fluid to the lesion area to flush out the specimen from the trachea and aspirate it for storage), brushing (by delivering a brush through the operating tube 25 to the lesion area and brushing the specimen for storage), and biopsy (by delivering biopsy forceps through the operating tube 25 to the lesion area and directly removing the specimen for storage).

[0018] In this embodiment, as Figure 2-3 The insertion component 2 further includes: The sleeve 21 has one end fixed to the operating frame 1 and the other end fitted with an end cap. The snake bone assembly 22 is sleeved and fixed inside the sleeve 21, and the snake bone assembly 22 is disposed close to the end cap; Adjustment component 27 is disposed within the snake bone component 22; A light guide 23 and an objective lens 24 are fitted inside the sleeve 21 and the snake bone assembly 22.

[0019] In a preferred embodiment, one end of the light guide 23 and the objective lens 24 are fixed to the end cap, and the other end is connected to an external light source and an image processor via the operating frame 1 and the connector 7. Specifically, the light guide 23 is made of high-transmittance glass or acrylic resin drawn into fine fibers, which can effectively guide light through the end cap to illuminate the object being observed. The objective lens 24 has a built-in high-performance camera to record the shape of internal organs in color to assist in observation. A micro motor connected to the auxiliary adjustment button is provided in the operating frame 1, and the micro motor can adjust the insertion component 2.

[0020] In this embodiment, as Figure 3 The snake bone assembly 22 includes: Multiple snake-bone rings 221 are configured and connected sequentially by hinges; Multiple bent steel wires 222 are provided to connect the snake-bone ring 221 and the adjustment knob 6. Specifically, the snake-bone ring 221 is deflected by adjusting the adjustment knob 6, thereby adjusting the orientation of the insertion component 2 to avoid the insertion component 2 touching and irritating the tube wall, causing problems such as coughing or bronchospasm.

[0021] In this embodiment, as Figure 3-4 The adjustment component 27 includes: Pressure pipe 271 is disposed between the delivery pipe 26 and the operating pipe 25, and connects the delivery pipe 26 and the operating pipe 25; Multiple support rings 272 are configured and are correspondingly fitted into a single snake-bone ring 221. The specific support ring 272 deflects with the corresponding snake-bone ring 221, and the snake-bone ring 221 is limited in movement and can be actively controlled, so as to provide support for the support ring 272. Two control wires 273 are arranged and respectively sleeved on the operating tube 25 and the conveying tube 26. The control wires 273 pass through the support ring 272 and are connected to the micro motor. The auxiliary adjustment button controls the contraction and relaxation of the control wires 273.

[0022] It should be explained that when obtaining samples using brushing or biopsy operations, if the sample is aspirated through the operating tube 25 before being transported by the brush and biopsy forceps, while keeping the insertion component 2 inside the body, pressing the auxiliary adjustment button causes the two control wires 273 to retract respectively, thereby closing the operating tube 25 and the delivery tube 26. At this time, the suction valve is first pressed to create a negative pressure in the operating tube 25, and then the water valve is pressed to deliver cleaning fluid into the delivery tube 26 to increase the pressure in the delivery tube 26. A pressure difference is formed between the operating tube 25 and the delivery tube 26, causing the pressure tube 271 to open. The cleaning fluid enters the operating tube 25 and is discharged from the suction port 5 to clean the inner wall of the operating tube 25. After cleaning, the brush or biopsy forceps are then inserted, which can effectively prevent infection.

[0023] In a preferred embodiment, the pressure tube 271 has a built-in pressure valve and a check valve, which only allows communication from the delivery tube 26 to the operating tube 25. The opening pressure of the pressure valve is greater than the maximum suction pressure that the suction valve can adjust. This effectively prevents the pressure valve from opening due to negative pressure suction when the operating tube 25 is used to suction secretions, which would cause secretions to enter the operating tube 25 through the delivery tube 26 and the pressure tube 271, resulting in blockage and contamination of the delivery tube 26.

[0024] In a preferred embodiment, the support ring 272 has an opening on one side that allows the control wire 273 to pass through. The support ring 272 near the end cap corresponds to the adjustment of the delivery tube 26, and the subsequent support ring 272 corresponds to the adjustment of the operating tube 25. The openings of the two parts of the support ring 272 face opposite directions. Specifically, when the tracheal pressure rises sharply, the delivery tube 26 can be controlled to close, preventing blood and sputum from flowing back in and causing blockage and contamination. At the same time, when the delivery tube 26 is blocked, the valve is usually removed, rinsed with sterile saline, and then replaced. When the operating tube 25 is blocked, it is rinsed with 5-10 ml of saline, and the secretions and blood are aspirated by intermittently pressing the suction valve, or the blood clot is cleared into the body with biopsy forceps before being removed. The whole process is cumbersome, and the risk of infection will increase accordingly. Direct cleaning process, connecting the operating tube 25 and the delivery tube 26 to form a loop, and cleaning the delivery tube 26 and the operating tube 25 simultaneously, shortens the processing steps and indirectly reduces the risk of infection.

[0025] In a preferred embodiment, the outer and inner walls of the operating tube 25 are respectively provided with an outer support curved platform 251 and an inner closed curved platform 252. The outer support curved platform 251 and the inner closed curved platform 252 on one side of the operating tube 25 form an adjustment group. The two adjustment groups are staggered along the axial direction of the operating tube 25, with the adjustment group closer to the end cap on the side near the conveying pipe 26. The edge of this adjustment group is the connection point of the control wire 273, corresponding to the tension point of the operating tube 25. The other adjustment group is close to the support ring 272, and the corresponding outer support curved platform 251 abuts against the support ring 272. This is the limiting point of the operating tube 25. The overall inner diameter of the operating tube 25 is relatively large. Therefore, closing the operating tube 25 by squeezing or bending would result in a large degree of deformation, which would reduce its service life. By setting two adjustment groups to control the closing of the operating tube 25, the inner diameter of part of the tube is reduced, thus reducing the degree of deformation required for the closing of the operating tube 25. At the same time, the inner diameter of the operating tube 25 at the corresponding adjustment group position is reduced. When inserting the brush and biopsy forceps, the corresponding position is inevitably subjected to more wear. However, the corresponding adjustment group increases the wall thickness of the operating tube 25, which can effectively reduce the impact of wear.

[0026] In a preferred embodiment, the conveying pipe 26 is fitted with a compression sleeve 261, one end of which abuts against the support ring 272. The side wall of the compression sleeve 261 has a groove for placing the control wire 273, and the compression sleeve 261 is fitted with a deflection radius on the end face of the support ring 272. Specifically, when the control wire 273 is pulled, the compression sleeve 261 deflects under the support of the support ring 272, causing the conveying pipe 26 to bend, thereby closing the conveying pipe 26.

[0027] In practice, the insertion component 2 is inserted into the main bronchus and each lobe bronchus is examined sequentially from top to bottom. If secretions are encountered that affect the delivery of the insertion component 2, the suction valve can be pressed to aspirate the secretions to the outside through the operating tube 25. After reaching the lesion location, the specimen can be collected using a brushing or biopsy procedure. If the brush and biopsy forceps were aspirated through the operating tube 25 before delivery, the insertion component 2 is kept in the body. Pressing the auxiliary adjustment button causes the two control wires 273 to contract respectively, thereby closing the operating tube 25 and the delivery tube 26. At this time, the suction valve is pressed to create negative pressure in the operating tube 25. Then, the water valve is pressed to deliver cleaning fluid into the delivery tube 26 to increase the pressure in the delivery tube 26. A pressure difference is created between the operating tube 25 and the delivery tube 26, causing the pressure tube 271 to open. The cleaning fluid enters the operating tube 25 and is discharged through the suction port 5 to clean the inner wall of the operating tube 25. After cleaning, the brush or biopsy forceps is inserted again for sampling.

[0028] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
