Description

Technical Field

[0001] The invention belongs to the technical field of bronchoscope auxiliary instruments, and in particular relates to a bronchoscope bracket. Background Art

[0002] A bronchoscope is a medical device that is inserted into the patient's lower respiratory tract through the mouth or nose and is used for observation, biopsy sampling, bacteriological and cytological examinations of lobar, segmental and subsegmental bronchial lesions. It can be used in conjunction with a TV system for photography, teaching and dynamic recording. The connected biopsy sampling accessories can assist in the discovery of early lesions and can perform in vivo surgical operations such as polypectomy. It is suitable for bronchial and lung disease research and postoperative examinations. When using a bronchoscope, some medical staff will use a stent to assist in improving the stability of bronchoscope insertion. For example, a bronchoscope stent is proposed in patent announcement number CN110960183B.

[0003] When using an existing bronchoscope holder, it is necessary to pass the lower end pipeline of the bronchoscope through two rotating shafts and rotate the rotating shafts, and use the friction between the rotating shafts and the bronchoscope to drive the lower end of the bronchoscope to move, and apply lubricating fluid during the downward movement of the bronchoscope. When the patient undergoes a bronchoscopic examination, the lower end of the bronchoscope does not move forward all the time, but needs to be pulled back for inspection frequently. The pull-back inspection allows the doctor to re-examine the inspected area to ensure a comprehensive observation of the entire airway and avoid missing lesions. When using the rotating shaft to pull back the bronchoscope, the lubricating fluid applied to the lower end of the bronchoscope will cause the friction between the rotating shaft and the bronchoscope to decrease, thereby affecting the pull-back movement speed of the bronchoscope.

[0004] Therefore, a bronchoscope stent is proposed to solve the above problems. Summary of the invention

[0040] The trigger assembly 26 includes a trigger cylinder 261 rotatably arranged at the rear end of the right driving tube 81. The rear end of the right driving tube 81 is located in the trigger cylinder 261 and is fixedly connected to a trigger plate 262. The rear side wall of the trigger plate 262 is fixedly connected to a conductive block 27. The conductive block 27 is electrically connected to an external power supply. Two blocking plates 28 are fixedly connected to the rear inner wall of the trigger cylinder 261. The two blocking plates 28 are fixedly connected to the same spring between the trigger plate 262. Two conductive plates 29 are inlaid on the rear inner wall of the trigger cylinder 261. The conductive plate 29 on the left is electrically connected to the peristaltic pump 20 through the PLC controller 3, and the conductive plate 29 on the right is electrically connected to the recovery pump 25 through the PLC controller 3, which can control the application and recovery of the lubricating fluid on the surface of the bronchoscope.

[0041] The left side wall of the U-shaped tube 11 is fixedly connected to an air pressure sensor 37 , and the air pressure sensor 37 is electrically connected to the PLC controller 3 , so that the rubber ring 10 can be filled with an appropriate amount of air pressure.

[0042] The right side wall of the U-shaped tube 11 is fixedly connected with a venting pipe 38 , and a control valve 39 is provided in the venting pipe 38 , so as to discharge the gas in the U-shaped tube 11 .

[0043] The operating principle of the present invention is now described as follows: the medical staff inserts the bent rod 6 into the clamping frame 5 and fixes the bent rod 6 in the clamping frame 5 with the positioning bolts, then moves the mobile frame 1 to the front of the patient's bed, adjusts the position of the mobile frame 1, and controls the height of the hydraulic cylinder 4 through the console 2 to align the driving frame 7 with the patient's oral cavity. Then the medical staff holds the operating part of the bronchoscope with one hand and passes the lower end of the bronchoscope through the two rubber rings 10 with the other hand, and the lower end of the bronchoscope passes through the recovery ring tube 211 and the smear ring 131. At the same time, the medical staff can control the peristaltic pump 2 through the console 2 0 works, after the bent rod 6 is inserted into the clamping frame 5, the liquid outlet end of the peristaltic pump 20 and the liquid inlet end of the recovery pump 25 can be connected with the delivery tube 18 and the recovery tube 23 respectively, and the peristaltic pump 20 will deliver the lubricating liquid inside the delivery cylinder 19 to the delivery cavity 132, and deliver it to the coating head 17 (the number of coating heads 17 is multiple) through the telescopic airbag 16, and evenly apply the lubricating liquid on the surface of the bronchoscope through the coating head 17, and then the medical staff connects the lower end of the bronchoscope with the patient's trachea, and then the medical staff controls the peristaltic pump 20 to suspend work through the console 2 to stop the delivery of the lubricating liquid;

[0044] Before going deeper, the medical staff controls the micro air pump 12 through the console 2. The micro air pump 12 delivers external gas to the two driving tubes 81 through the U-shaped tube 11, and delivers it to the two rubber rings 10 through the air outlet 40, so that the rubber rings 10 are inflated. After the rubber rings 10 are inflated, they will contact the bronchoscope. After the air pressure sensor 37 detects that the air pressure inside the rubber ring 10 reaches the set threshold (50kPa), the air pressure sensor 37 will control the micro air pump 12 through the PLC controller 3. The pump 12 stops working, and the medical staff needs to relatively fix the control rod 33, the limiting cover 31 and the threaded rod 302 by the limiting bolt 32. Then the medical staff can stand on the right side of the driving frame 7 and rotate the trigger cylinder 261 clockwise. The trigger cylinder 261 will drive the blocking plates 28 on both sides to rotate together, and the trigger plate 262 is pushed by the spring force between the blocking plate 28 and the trigger plate 262. The trigger plate 262 will drive the right driving tube 81 to rotate clockwise, and the right driving tube 81 will rotate clockwise through the gear transmission. The dynamic component drives the driving tube 81 on the left to rotate counterclockwise, and the two driving tubes 81 will drive the two expanded rubber rings 10 to rotate downward in opposite directions, so as to transport the lower end of the bronchoscope downward and move the lower end of the bronchoscope into the patient's bronchus. When the trigger tube 261 rotates clockwise, the spring between the left blocking plate 28 and the trigger plate 262 is used to push the driving tube 81 on the right to rotate, and the spring between the left blocking plate 28 and the trigger plate 262 will be compressed, so that the distance between the left blocking plate 28 and the trigger plate 262 becomes smaller, and the conductive block 27 on the rear side of the trigger plate 262 will contact the conductive plate 29 on the left. The conductive block 27 is electrically connected to the external power supply, and the conductive plate 29 on the left works through the PLC controller 3 and the peristaltic pump 20. When the conductive block 27 contacts the conductive plate 29 on the left, an electrical signal will be transmitted to the PLC controller 3. After receiving the electrical signal, the PLC controller 3 will control the peristaltic pump 20 to work. Referring to the above principle, the lubricating liquid can be evenly applied to the surface of the bronchoscope.

[0045] Similarly, when the medical staff rotates the trigger cylinder 261 counterclockwise to pull back the bronchoscope, the conductive block 27 will contact the conductive plate 29 on the right side, and the conductive plate 29 on the right side is electrically connected to the recovery pump 25 through the PLC controller 3. The PLC controller 3 will control the recovery pump 25 to work. When the lower end of the bronchoscope moves upward, the lubricating fluid attached to the surface of the bronchoscope will be scraped off by the elastic ring 212, and will flow to the vicinity of the recovery hole 22 under the action of gravity, and will be transported to the recovery cylinder 24 through the recovery pump 25 for storage, so as to avoid the problem that the lubricating fluid on the surface of the bronchoscope will reduce the friction of the rubber ring 10 and affect the movement of the bronchoscope.

[0046] When the right driving tube 81 is rotating, the right driving tube 81 will drive the control rod 33 to rotate through the pulley transmission assembly, and the control rod 33 will drive the threaded rod 302 to rotate together through the limit cover 31 and the limit bolt 32, and drive the threaded tube 34 to move through the thread cooperation, and the threaded tube 34 will drive the indicator plate 35 to move together. Through the position of the indicator plate 35, the depth gauge 36 can be used to assist medical staff in determining the position of the bronchoscope in the patient's bronchus, thereby improving the convenience for medical staff to determine the specific location of the lesion inside the patient's bronchus.

[0047] 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 principle of the present invention should be included in the protection scope of the present invention.
