Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a split-type fiber bronchoscope used for sputum suction. Background Art

[0002] Fiberoptic bronchoscopes have multiple uses. It is a routine clinical procedure to insert a bronchoscope into the patient's bronchus and perform precise suction of sputum together with a suction tube.

[0003] At present, there are various models of fiberoptic bronchoscopes with suction function. According to the type of disinfection, they can be mainly divided into two categories. One is a disposable sputum-collecting suction tube bronchoscope, which is only used for a single patient. Patients do not have to wait in line for daily suction operations. It is convenient to use a single person with a single tube, and it also avoids the risk of cross infection. The disadvantage is that the cost of use is extremely high, and it is not suitable for popular use. The other type is the fiberoptic bronchoscope with a fixed suction tube that is currently used in clinical practice. Patients use it in turn, and disinfection is performed after each use, which is extremely inefficient. Since the number of suction times per person for hospital-related patients can reach up to 2 times a day, disinfection and sterilization are required after each use. The disinfection operation cycle is long, resulting in extremely low efficiency of suction operation, time-consuming and labor-intensive, and there may also be problems with incomplete sterilization, and there is a risk of cross infection.

The bottom of the detachable sub-body 2 is provided with a fiberoptic bronchoscope body 6 sleeved in the sleeve 5, and a lens 7 is fixedly connected to the bottom of the fiberoptic bronchoscope body 6. The bottom of the detachable sub-body 2 is provided with a sputum suction tube 8 sleeved in the sleeve 5, and a sputum suction hole 9 is provided at the bottom of the sputum suction tube 8. The bottom of the sleeve 5 is provided with a sealing mechanism. The surface of the detachable sub-body 2 near the top is provided with an elastic negative pressure blocking valve 10, and a negative pressure connector 11 is fixedly connected to the outer contour of the elastic negative pressure blocking valve 10. The surface of the detachable sub-body 2 near the bottom is provided with a biopsy forceps inlet 12;

[0030] First, the bronchoscope body 1 and the detachable sub-body 2 are installed through the snap-in mechanism, and then the bronchoscope body 6 and the suction tube 8 are installed in the sleeve 5 through the fixing mechanism. At this time, the lens 7 at the bottom of the bronchoscope body 6 is sealed by the sealing mechanism, and then the negative pressure connector 11 is connected to the negative pressure machine. When it is needed, the sleeve 5 is sent into the patient's body, and then the display screen connected to the display connecting line 3 is used to observe that the lens 7 at the bottom of the bronchoscope body 6 reaches the position where suction is required, and then the push handle 4 is pushed to rotate the lens 7 so that the operator can carefully observe the suction situation in the patient's body, and then press the elastic negative pressure blocking valve 10 to suck out the sputum through the suction hole 9 at the bottom of the suction tube 8, thereby completing the suction operation of the patient. At this time, the operator can quickly disassemble the detachable sub-body 2 and then replace it, so that the operator's suction operation efficiency is increased.

[0031] The clamping mechanism includes a clamping groove 13 provided on the fiberoptic bronchoscope main body 1 near one side of the detachable sub-body 2, a clamping block 14 is fixedly connected to one side of the detachable sub-body 2 near the clamping groove 13, a movable cavity 18 is provided through the top of the inner wall of the clamping groove 13, a hexagonal rod 16 is limitedly slidably connected to the inner wall of the movable cavity 18, a lifting block 15 is fixedly connected to the top of the hexagonal rod 16, a reset spring 19 sleeved on the outer contour of the hexagonal rod 16 is provided on the inner wall of the movable cavity 18, a limiting groove 21 for the clamping of the hexagonal rod 16 is provided on the top of the clamping block 14, a retaining ring 17 is fixedly connected to the outer contour of the hexagonal rod 16 near the bottom, a retaining ring 20 is threadedly connected to the inner wall of the movable cavity 18 near the top, and two ends of the reset spring 19 are in contact with the bottom and top of the retaining ring 17 and the retaining ring 20 respectively;

At this time, the operator inserts the clamping block 14 on the detachable sub-body 2 into the clamping groove 13. When the limiting groove 21 on the clamping block 14 is aligned with the active cavity 18, the elasticity generated by the squeezed return spring 19 is used to drive the hexagonal rod 16 on the inner wall of the retaining ring 17 to complete the clamping process in the limiting groove 21. When the return spring 19 needs to be replaced, because the top-down shape of the inner cavity of the retaining ring 20 and the main view shape of the retaining ring 17 are both hexagonal, the operator rotates the lifting block 15, thereby driving the hexagonal rod 16 to rotate through the lifting block 15, and driving the retaining ring 20 to move it out of the active cavity 18 through the rotating hexagonal rod 16. At this time, the return spring 19 can be taken out and replaced.

[0033] The fixing mechanism includes an externally threaded fixing cylinder 101 fixedly connected to the bottom of the fiberoptic bronchoscope body 1, the bottom of the externally threaded fixing cylinder 101 is detachably connected to the sleeve 5, an internally threaded connecting cylinder 24 is fixedly connected to the outer contour of the sleeve 5 near the top, a fixing cavity 22 for limiting and sliding connection of the internally threaded connecting cylinder 24 is provided through the bottom of the detachable auxiliary body 2, the inner wall of the internally threaded connecting cylinder 24 is threadedly connected to the outer contour of the externally threaded fixing cylinder 101, a connecting ring 241 is fixedly connected to the outer contour of the internally threaded connecting cylinder 24 near the top, and both sides of the inner cavity of the detachable auxiliary body 2 are fixedly connected to limiting rings 23;

[0034] By inserting the externally threaded fixing tube 101 at the bottom of the bronchoscope main body 1 into the detachable sub-body 2, the bronchoscope body 6 in the externally threaded fixing tube 101 is inserted into the other side of the inner cavity of the sleeve 5, so that the outer contour of the bronchoscope body 6 contacts the outer contour of the suction tube 8, and then the internally threaded connecting tube 24 is rotated with a wrench so that the inner wall of the internally threaded connecting tube 24 is threadedly fixed to the outer contour of the externally threaded fixing tube 101, and the connecting ring 241 is limited by two limiting rings 23 when moving up and down.

[0035] The sealing mechanism includes an externally threaded connecting tube 25 fixedly connected to the bottom of the sleeve 5, a sealing tube 26 is threadedly connected to the outer contour of the externally threaded connecting tube 25, a high-definition lens 27 is fixedly connected to the bottom of the sealing tube 26, and a sealing rubber ring 29 is fixedly connected to the outer contour of the sealing tube 26 near the fixing ring 28 in an equidistant array, and a sealing groove for the sealing rubber ring 29 to be engaged is provided on the outer contour of the fixing ring 28. The bottom of the lens 7 is connected to one side of the top of the high-definition lens 27, and the other side of the high-definition lens 27 is provided with a connecting hole connected to the sputum suction hole 9. The bottom of the externally threaded connecting tube 25 is fixedly connected to the fixing ring 28.

[0036] The operator fixes the external threaded connecting tube 25 and the outer contour of the sealing tube 26 with threads, and seals it through the sealing rubber ring 29 on the inner wall of the sealing tube 26 and the sealing groove opened on the outer contour of the fixing ring 28, and forms a labyrinth seal on the bottom end of the sleeve 5 by connecting multiple sealing rubber rings 29 and the sealing groove to increase the sealing effect of the equipment. When the lens 7 is suctioning sputum in the patient's body, the sealing rubber ring 29 and the sealing groove are used to seal the connection between the sleeve 5 and the sealing tube 26, and then the high-definition lens 27 at the bottom of the sealing tube 26 is used to seal the lens 7 when it is working, and then the connecting hole opened on the high-definition lens 27 is used to suck the sputum into the sputum suction tube 8 through the sputum suction hole 9 to complete the sputum suction operation on the patient.

[0037] Working principle: First, pull the lifting block 15 upward to drive the retaining ring 17 on the outer contour of the hexagonal rod 16 to move upward, and drive the reset spring 19 to move upward through the retaining ring 17, and squeeze the reset spring 19 that moves upward through the retaining ring 20. At this time, the operator inserts the clamping block 14 on the detachable sub-body 2 into the clamping groove 13. When the limiting groove 21 on the clamping block 14 is aligned with the active cavity 18, the elasticity generated by the squeezed reset spring 19 is used to drive the hexagonal rod 16 on the inner wall of the retaining ring 17 to be inserted into the limiting groove 21, thereby completing the clamping process of the fiberoptic bronchoscope main body 1 and the detachable sub-body 2;

[0038] Then, the external thread fixing cylinder 101 at the bottom of the fiberoptic bronchoscope main body 1 is inserted into the detachable secondary body 2, so that the fiberoptic bronchoscope body 6 in the external thread fixing cylinder 101 is inserted into the other side of the inner cavity of the sleeve 5, so that the outer contour of the fiberoptic bronchoscope body 6 contacts the outer contour of the sputum suction tube 8, and then the internal thread connecting cylinder 24 is rotated with a wrench so that the inner wall of the internal thread connecting cylinder 24 is threadedly fixed with the outer contour of the external thread fixing cylinder 101, thereby fixing the fiberoptic bronchoscope body 6 and the sputum suction tube 8 in the sleeve 5;

[0039] Then, the external threaded connecting tube 25 is fixed to the outer contour of the sealing tube 26 by thread, and the sealing process is performed by the sealing rubber ring 29 on the inner wall of the sealing tube 26 and the sealing groove opened on the outer contour of the fixing ring 28. In addition, a labyrinth sealing process is formed on the bottom end of the sleeve 5 by connecting multiple sealing rubber rings 29 and the sealing groove to increase the sealing effect of the equipment. When the lens 7 is suctioning sputum in the patient's body, the sealing rubber ring 29 and the sealing groove are used to seal the connection between the sleeve 5 and the sealing tube 26.

[0040] When it is needed, the sleeve 5 is inserted into the patient's body, and then the display screen connected to the display connecting line 3 is used to observe that the lens 7 at the bottom of the bronchoscope body 6 reaches the position where suction is required. Then, the push handle 4 is pushed to rotate the lens 7 so that the operator can carefully observe the suction of sputum in the patient's body. Then, the elastic negative pressure blocking valve 10 is pressed, and the connecting hole opened on the high-definition lens 27 is used to suck the sputum into the suction tube 8 through the suction hole 9 to complete the suction operation on the patient.

[0041] Finally, the operator rotates the sealing cylinder 26 to separate the sealing cylinder 26 from the externally threaded connecting tube 25, and then rotates the internally threaded connecting cylinder 24 with a wrench to separate the internally threaded connecting cylinder 24 from the externally threaded fixed cylinder 101. At this time, the operator pulls up the lifting block 15 to drive the hexagonal rod 16 to move out of the limiting groove 21 provided on the clamping block 14. At this time, the bronchoscope main body 1 and the detachable sub-body 2 can be separated, and then the bronchoscope body 6 and the lens 7 can be moved out of the old sleeve 5, and then the new detachable sub-body 2 can be taken out to replace it.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
