Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a bronchoscope protective sleeve. Background Technology

[0002] A bronchoscope is a medical device inserted through the mouth or nose into a patient's lower respiratory tract for observation, biopsy sampling, bacteriological and cytological examination of lesions in the lobes, segments, and subsegments of the bronchi. When used with a TV system, it can perform photography, teaching, and dynamic recording. Through connected biopsy attachments, it can assist in the detection of early lesions and facilitate internal surgical procedures such as polyp removal. It is suitable for bronchial and lung disease research and postoperative examinations.

[0003] Bronchoscopes do not have protective mechanisms. When not in use, bronchoscopes are exposed to the environment, and the optical lens at the end may be bumped or knocked, which may damage it and affect its normal use. Utility Model Content

[0004] The purpose of this invention is to provide a bronchoscope protective sleeve to solve the technical problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides a bronchoscope protective sleeve, including an outer sleeve and an inner sleeve inserted inside the outer sleeve. A top limiting ring is fixedly connected to the top of the outer sleeve, and a sealing ring is threadedly installed at the lower end of the outer sleeve. The inner sleeve is restricted between the top limiting ring and the sealing ring. The outer sleeve is made of rigid material, and the inner sleeve is made of soft material.

[0006] Preferably, the top of the outer casing has two symmetrically distributed positioning frames fixedly connected, a rotating shaft is rotatably inserted between the inner walls of the positioning frames, a connecting rod is fixedly connected to the rotating shaft, a clamping rod is fixedly connected to the other end of the connecting rod, and a torsion spring is fixedly connected between the connecting rod and the positioning frame.

[0007] Preferably, one end of the rotating shaft has an external thread, and a nut is threaded onto the end of the rotating shaft.

[0008] Preferably, the clamping rod has a cylindrical structure.

[0009] Preferably, the connecting rod is located inside the positioning frame, and the width of the connecting rod is smaller than the width of the positioning frame.

[0010] Preferably, the lower end of the outer casing has an external thread, the top of the sealing ring has an internal thread, and the sealing ring is threadedly installed on the lower end of the outer casing.

[0011] Preferably, the outer circumferential sidewall of the inner sleeve abuts against the inner circumferential sidewall of the outer sleeve.

[0012] Preferably, both the inner sleeve and the outer sleeve are cylindrical.

[0013] Preferably, the outer and inner sleeves are covered with an antibacterial coating.

[0014] Preferably, a rubber sleeve is fixedly connected to the clamping rod.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] 1. In this utility model, the bronchoscope is inserted into the inner sleeve to achieve the purpose of protecting the bronchoscope; since the inner sleeve is made of flexible material, it helps to protect the bronchoscope and has a buffering effect in direct contact; the outer sleeve is made of rigid material, which improves the protection ability in case of impact.

[0017] 2. In this utility model, the bronchoscope is passed through the top limiting ring and then the two clamping rods are released. At this time, the torsion spring releases its elastic force, which drives the connecting rod and the clamping rods to rotate, so that the two clamping rods clamp the bronchoscope. This can achieve the purpose of installing the entire protective sleeve. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The present invention will be further explained below with reference to specific embodiments.

[0031] like Figure 1-7 As shown, the bronchoscope protective sleeve provided in this embodiment includes an outer sleeve 1 and an inner sleeve 2 inserted inside the outer sleeve 1. A top limiting ring 4 is fixedly connected to the top of the outer sleeve 1, and a sealing ring 3 is threadedly installed at the lower end of the outer sleeve 1. The inner sleeve 2 is restricted between the top limiting ring 4 and the sealing ring 3. The outer sleeve 1 is made of rigid material, and the inner sleeve 2 is made of soft material.

[0032] The bronchoscope is inserted into the inner sleeve 2 to protect it. Since the inner sleeve 2 is made of flexible material, it helps to protect the bronchoscope and provides a cushioning effect in direct contact. The outer sleeve 1 is made of rigid material to improve protection against impacts.

[0033] Two symmetrically distributed positioning frames 5 are fixedly connected to the top of the outer casing 1. A rotating shaft 7 is rotatably inserted between the inner walls of the positioning frames 5. A connecting rod 6 is fixedly connected to the rotating shaft 7. A clamping rod 10 is fixedly connected to the other end of the connecting rod 6. A torsion spring 8 is fixedly connected between the connecting rod 6 and the positioning frame 5.

[0034] The bronchoscope is inserted through the top limiting ring 4 and then the two clamping rods 10 are released. At this time, the torsion spring 8 releases its elastic force, which drives the connecting rod 6 and the clamping rods 10 to rotate, so that the two clamping rods 10 clamp the bronchoscope. This achieves the purpose of installing the entire protective cover.

[0035] One end of the rotating shaft 7 has an external thread 101, and the end of the rotating shaft 7 is threaded with a nut 9; by rotating the nut 9, the end of the nut 9 comes into contact with the side wall of the positioning frame 5, which can achieve the purpose of locking the connecting rod 6 and the clamping rod 10.

[0036] Furthermore, the clamping rod 10 has a cylindrical structure, and a rubber sleeve is fixedly connected to the clamping rod 10; this reduces wear on the bronchoscope when clamping the surface of the bronchoscope.

[0037] Link 6 is located inside the positioning frame 5, and the width of link 6 is smaller than the width of positioning frame 5.

[0038] The lower end of the outer sleeve 1 has an external thread 101, and the top of the sealing ring 3 has an internal thread 301. The sealing ring 3 is threaded onto the lower end of the outer sleeve 1. When the inner sleeve 2 needs to be installed, it needs to be inserted into the lower part of the outer sleeve 1, and the inner sleeve 2 needs to be completely inserted into the inner sleeve 1. Then, the sealing ring 3 is screwed on at the lower end of the outer sleeve 1 to lock the inner sleeve 2. The inner sleeve 2 can be replaced periodically as needed.

[0039] The outer circumferential sidewall of the inner sleeve 2 abuts against the inner circumferential sidewall of the outer sleeve 1, thus better protecting the bronchoscope.

[0040] In addition, both the inner sleeve 2 and the outer sleeve 1 are cylindrical.

[0041] The outer sleeve 1 and inner sleeve 2 are coated with an antibacterial coating, thereby improving the hygienic properties of the protective sleeve. This coating not only helps reduce the risk of cross-infection but also extends the lifespan of the protective sleeve.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
