Abstract
Description
Technical Field
[0001] The utility model relates to an adjustable three-way connecting device for a fiberoptic bronchoscope. Background Art
[0002] Fiberoptic 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 with TV systems for photography, teaching and dynamic recording. The bronchoscope is equipped with a biopsy sampling device, which can help discover early lesions and perform internal surgical operations such as polypectomy. It is a good precision instrument for the study of bronchial and lung diseases and postoperative examinations. After its invention, fiberoptic bronchoscopes (fiberoptic bronchoscopes) have been widely used in clinical practice. In addition to making great progress in the diagnosis of respiratory diseases, it has also been widely used in treatment.
[0003] The three-way connection device of the bronchoscope currently used in clinical practice is a common three-way tube structure, and a bronchoscope fixing structure is set at the insertion end of the bronchoscope. There is a small hole in the center of the structure, and the bronchoscope passes through the small hole when in use. The small hole is only suitable for 5.5-size bronchoscopes. If the diameter of the bronchoscope is larger than this size, it cannot be inserted; if the diameter of the bronchoscope is smaller than this size, it will not be fixed after insertion, the pipeline is not sealed, and gas will escape from the small hole during use. Utility Model Content
[0004] The utility model aims to provide an adjustable fiberoptic bronchoscope three-way connecting device, which is used to solve the problem that the three-way connector cannot be adapted to various types of fiberoptic bronchoscopes.
[0005] In order to solve the above problems, the technical solution of the utility model is:
[0006] An adjustable fiberoptic bronchoscope three-way connection device comprises a three-way joint and an elastic conical sleeve. The elastic conical sleeve has a through hole in its center for the fiberoptic bronchoscope to pass through. The thinner end of the elastic conical sleeve can be detachably extruded and inserted into the three-way joint interface.
[0007] It also includes a plug cap for closing the through hole, and the plug cap is connected to the thicker end of the elastic conical sleeve through a first connecting band.
[0008] It also includes a connecting ring which is sleeved on the three-way joint, and the connecting ring is connected to the thicker end of the elastic conical sleeve through a second connecting belt.
[0009] A plurality of scale lines are arranged on the conical surface of the elastic conical sleeve, and each scale line corresponds to a fiberoptic bronchoscope of a different model.
[0010] The elastic conical sleeve is made of rubber material or TPE material.
[0011] The beneficial effects of the utility model are as follows: an inclined surface is formed between the tapered surface of the elastic conical sleeve and the three-way joint interface, and the aperture of the through hole is adjusted by extrusion by utilizing the change in insertion depth, so that it can be passed through by bronchoscope insertion tubes of different diameters and can fit tightly with the tube wall, thereby adapting to different models of bronchoscopes and ensuring airtightness during use. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] The utility model is further described below in conjunction with the accompanying drawings:
[0013] Figure 1 It is a three-dimensional structural schematic diagram of the utility model.
[0014] Figure 2 It is a schematic diagram of the cross-sectional structure of the utility model.
[0015] In the figure: an elastic conical sleeve 1, a scale line 2, a three-way joint 3, a connecting ring 4, a second connecting belt 5, a first connecting belt 6, a plug cap 7, and a through hole 8. DETAILED DESCRIPTION
[0016] 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.
[0017] like Figure 1 and 2 As shown, an adjustable three-way connection device for a fiberoptic bronchoscope includes a three-way connector 3 and an elastic conical sleeve 1. A through hole 8 for the fiberoptic bronchoscope to pass through is provided in the center of the elastic conical sleeve 1. The thinner end of the elastic conical sleeve 1 can be detachably extruded and inserted into the interface of the three-way connector 3.
[0018] The device further comprises a plug cap 7 for closing the through hole 8, and the plug cap 7 is connected to the thicker end of the elastic conical sleeve 1 through a first connecting band 6. When the fiberoptic bronchoscope is not inserted, the plug cap 7 is closed to ensure the airtightness of the device. In addition, the first connecting band 6 can also be replaced by a first connecting line.
[0019] It also includes a connecting ring 4 which is sleeved on the tee joint 3, and the connecting ring 4 is connected to the thicker end of the elastic conical sleeve 1 through a second connecting belt 5. This structure can prevent the elastic conical sleeve 1 from being lost.
[0020] A plurality of scale lines 2 are arranged on the conical surface of the elastic conical sleeve 1, and each scale line 2 corresponds to a different type of bronchoscope. When the elastic conical sleeve 1 is inserted into the three-way connector 3, the elastic conical sleeve 1 can be directly inserted to the corresponding scale line 2 according to the type of bronchoscope used, thereby simplifying the operation steps and improving the operation accuracy.
[0021] The elastic conical sleeve 1 is made of medical material, preferably rubber material or TPE material. During manufacturing, the elastic conical sleeve 1, the connecting ring 4, the second connecting belt 5 and the first connecting belt 6 are connected in an integrated manner.
[0022] Working principle: when in use, open the plug cap 7, first insert the bronchoscope insertion tube through the through hole 8 opened in the center of the elastic conical sleeve 1, and then insert the elastic conical sleeve 1 into the upper end interface of the three-way joint 3; when the diameter of the through hole 8 is consistent with the diameter of the bronchoscope, the tube wall of the bronchoscope insertion tube fits tightly with the inner wall of the through hole 8, and the elastic conical sleeve 1 is inserted into the upper end interface of the three-way joint 3, corresponding to the position of the middle scale line 2; when the diameter of the bronchoscope used is larger than the diameter of the through hole 8, the through hole 8 and the elastic conical sleeve 1 expand, and the elastic conical sleeve 1 is inserted into the upper end interface of the three-way joint 3 more shallowly, corresponding to the position of the lower scale line 2; when the diameter of the bronchoscope used is smaller than the diameter of the through hole 8, in order to achieve airtightness, the elastic conical sleeve 1 is inserted into the upper end interface of the three-way joint 3 more deeply, and the through hole 8 and the elastic conical sleeve 1 are squeezed and contracted, corresponding to the position of the uppermost scale line 2; when the bronchoscope is not inserted, close the plug cap 7 and the device is still in a closed state.
[0023] The contents described in the embodiments of this specification are merely an enumeration of the implementation forms of the utility model concept. The protection scope of the utility model should not be deemed to be limited to the specific forms described in the embodiments. The protection scope of the utility model also extends to equivalent technical means that can be thought of by those skilled in the art based on the concept of the utility model.
