Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a dental pad protection component and a bronchoscope. Background Art

[0002] In the medical field, bronchoscope is an important tool for examining and treating respiratory diseases. It helps doctors diagnose and treat by visualizing the inside of the respiratory tract. It is one of the key tools for treating many respiratory diseases.

[0003] Since the bronchoscope needs to enter the patient's mouth and throat during use, its surface is often easily damaged, such as being bitten by teeth or contacting other hard objects. In order to protect the service life and performance of the bronchoscope, the tooth pad protection assembly is designed to be installed in a specific part of the bronchoscope to provide an additional layer of protection to prevent teeth or other objects from directly contacting the surface of the bronchoscope.

[0004] Since most bronchoscope tooth pad protection components are designed as a tube mouthpiece, the insertion end of the bronchoscope is passed through the mouthpiece for use. This design can easily cause sliding with the teeth, which may cause misoperation or unnecessary discomfort during use. At the same time, the position of the patient's tongue may also affect the bronchoscope, which may interfere with the insertion end of the bronchoscope and cause difficulty in use.

[0030] 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.

[0031] Reference Figure 1-5 The utility model provides an embodiment: a tooth pad protection component, including a vertical rod 10 and a protection tube 14, the outer wall of the vertical rod 10 is slidably connected with an upper cross bar 4, the outer wall of the upper cross bar 4 is provided with an upper tooth pad 6, the outer wall of the vertical rod 10 is slidably connected with a lower cross bar 20, the outer wall of the lower cross bar 20 is provided with a lower tooth pad 11, the top of the lower cross bar 20 is fixedly connected with a square block 17, the inner wall of the square block 17 is slidably connected with a tongue depressor 12, the outer walls of the upper cross bar 4 and the lower cross bar 20 are threadedly connected with a bidirectional threaded rod 13, the upper tooth pad 6 and the lower tooth pad 11 support the teeth through the movement of the bidirectional threaded rod 13, and a limiting component is provided at the top of the square block 17, and the limiting component includes an L-shaped clamping rod 19.

[0032] The upper tooth pad 6 and the lower tooth pad 11 are usually made of soft and durable materials, such as medical grade silicone or rubber, to ensure that they do not cause discomfort to the patient. At the same time, they can be disassembled by bolts 8, making cleaning and disinfection more convenient, and also easy to replace or maintain, ensuring the hygiene and durability of the medical equipment.

[0033] The bidirectional threaded rod 13 is rotatably connected to the inside of the vertical rod 10, and a knob 7 is fixedly connected to the top of the vertical rod 10, and a connecting rod 5 is fixedly connected to the outer wall of the vertical rod 10, and the connecting rod 5 is fixedly connected to the protective tube 14, and a contact tube 15 is fixedly connected to the inside of the protective tube 14, and a plurality of ribs are arranged inside the contact tube 15, and a U-shaped spring piece 18 is fixedly connected to the top of the square block 17, and a pressing rod 16 is symmetrically fixedly connected to the outer wall of the U-shaped spring piece 18, and the pressing rod 16 is fixedly connected to the L-shaped clamping rod 19, and the tongue depressor 12 is limited by the L-shaped clamping rod 19, and the outer walls of the upper tooth pad 6 and the lower tooth pad 11 are both provided with bolts 8, which are detachably connected to the upper cross bar 4 and the lower cross bar 20 through the bolts 8.

[0034] The insertion bending part 9 is arranged inside the contact tube 15. The contact tube 15 is made of a harder material and has a smoother surface. A plurality of ribs are arranged inside the contact tube 15 to reduce friction and facilitate the sliding of the bronchoscope into the insertion bending part 9, so that the operation can be carried out smoothly.

[0035] A bronchoscope comprises an operating part 1, an insertion curved part 9 is arranged on the outer wall of the operating part 1, an eyepiece part 2 is arranged at one end of the operating part 1 away from the insertion curved part 9, a light guide connecting part 3 is arranged on the outer wall of the operating part 1, and the insertion curved part 9 is arranged inside a contact tube 15.

[0036] The operating part 1 is the control part of the bronchoscope. By operating this part, the movement and lighting of the bronchoscope and other functions can be controlled, so that the doctor can observe and operate accurately. The light guide connecting part 3 connects the light source and the optical fiber of the bronchoscope to provide the doctor with a clear observation field. The eyepiece part 2 is the observation part of the bronchoscope. The doctor can directly observe the internal conditions of the trachea, bronchi and lungs through the eyepiece part 2, which is convenient for diagnosis and treatment. The insertion bending part 9 of the bronchoscope is usually designed to be flexible, so that it can be more easily inserted into the body through the oral cavity or nasal cavity.

[0037] Working principle: The insertion bend 9 slides inside the contact tube 15. When using the tooth pad protection component, first, the upper tooth pad 6 and the lower tooth pad 11 are respectively pressed against the upper teeth and the lower teeth, and then the knob 7 is turned to drive the bidirectional threaded rod 13 to separate the upper cross bar 4 from the lower cross bar 20 to prevent the teeth from rubbing against the insertion curved portion 9 and protect the bronchoscope from being damaged during operation. At the same time, the tongue depressor 12 can effectively fix the patient's tongue position to prevent the tongue from being blocked by the insertion curved portion 9 of the bronchoscope, thereby ensuring the smooth operation. The length of the tongue depressor 12 can be adjusted by squeezing the pressing rod 16 to separate the notch of the U-shaped spring sheet 18 to both sides, thereby making the L-shaped clamping rod 19 away from the tongue depressor 12, releasing the limit of the L-shaped clamping rod 19 on the tongue depressor 12, and releasing the pressing rod 16 when it is adjusted to a suitable position. The L-shaped clamping rods 19 on both sides are close to the tongue depressor 12 through the elastic force of the U-shaped spring sheet 18 and clamp and fix the tongue depressor 12, so that the length of the tongue depressor 12 can be adjusted according to different patients.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
