Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a human cavity endoscope. Background Art

[0002] The human body has a complex structure and has many cavities connected to the outside world, including the nasal cavity, oral cavity, rectum, vagina, etc. The rectum and vagina are usually closed, but in the event of infection or inflammation, the cavities need to be opened for examination or treatment using an endoscope, applicator, etc.

[0003] In the prior art, when examining a diseased cavity, a rigid columnar body is usually coated with lubricating grease on its surface and then inserted into the cavity from the entrance of the cavity (such as the anus and vaginal opening). During this process, the columnar body contacts and rubs against the inner wall of the cavity. Although the lubricating grease is applied, as the columnar body goes deeper, the grease gradually decreases, and the friction area between the columnar body and the inner wall of the cavity gradually increases and becomes harder, which will make the patient feel unbearable pain, making it impossible for medical staff to complete the expected examination or treatment work, and will leave a great psychological shadow on the patient, making the patient more resistant to later treatment work, thereby delaying the disease.

[0004] Therefore, the inventor needs to design a new human cavity endoscope to overcome the above problems. Summary of the invention

[0005] The main purpose of the present application is to provide a human cavity endoscope to solve the problem of friction generated when treating the cavity in the related art.

[0006] In order to achieve the above-mentioned purpose, the present application provides a human cavity endoscope, including a lens barrel, one end of an annular elastic telescopic part is fixedly connected to the inner wall of the top of the lens barrel, the other end of the annular elastic telescopic part is fixedly connected to one end of an annular covering film, and the other end of the annular covering film extends out of the bottom of the lens barrel, rolls upward and is fixedly connected to a retaining ring.

[0007] Preferably, the annular elastic telescopic member is detachably connected to the lens barrel.

[0008] Preferably, the top of the annular elastic telescopic member is fixedly connected to an annular plate, the bottom of the annular plate is fixedly connected to an annular latch, and the top inner wall of the lens barrel is provided with an annular groove matching the annular latch.

[0009] Preferably, the lens barrel, the annular elastic telescopic member and the annular covering film are all made of transparent material.

[0010] Preferably, the bottom of the lens barrel has a chamfer.

[0011] Preferably, both ends of the annular elastic telescopic member are fixedly connected to the annular plate and the annular covering film respectively by hot melting.

[0012] Preferably, the annular elastic telescopic member is made of highly elastic polyurethane.

[0013] Preferably, a hand-held portion is fixedly provided on the top of the lens barrel.

[0014] Preferably, the annular covering film is made of polypropylene.

[0015] The human body cavity endoscope provided by the utility model has the following beneficial effects compared with the prior art:

[0016] During the process of the lens barrel going deeper inward, since the retaining ring is pressed and fixed and cannot move, the lower end of the annular covering film is always subjected to tension, so that the annular covering film inside the lens barrel is continuously rolled outward and laid on the inner wall of the cavity, so that the lens barrel does not contact the inner wall of the cavity. During the process of the lens barrel going deeper, the lens barrel does not rub against the inner wall of the cavity, which makes it less likely for the patient to feel pain, and the patient no longer resists the treatment of cavity diseases, thereby improving the treatment efficiency.

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] like Figures 1 to 5As shown, a human cavity endoscope comprises a lens barrel 1, one end of an annular elastic telescopic member 2 is fixedly connected to the inner wall of the top of the lens barrel 1, the other end of the annular elastic telescopic member 2 is fixedly connected to one end of an annular covering film 3, the other end of the annular covering film 3 extends out of the bottom of the lens barrel 1 and then rolls up and is fixedly connected to a retaining ring 4; when working, when it is necessary to open the patient's cavity, the lens barrel 1 is made to face the cavity entrance, the retaining ring 4 is pressed around the cavity entrance, an auxiliary tool with a circular arc surface at the end such as a piston is inserted into the lens barrel 1, and the annular covering film 3 is fixedly connected to the inner wall of the top of the lens barrel 1, and the annular covering film 3 is fixedly connected to the inner wall of the lens barrel 1. The inner wall of the lens barrel 1 is wetted, and then the entrance of the cavity is opened by an auxiliary tool, and then the auxiliary tool and the lens barrel 1 go deep inward. During this process, since the retaining ring 4 is pressed and fixed and cannot move, the lower end of the annular covering film 3 is always subjected to tension, so that the annular covering film 3 located inside the lens barrel 1 is continuously rolled outward and laid on the inner wall of the cavity, so that the lens barrel 1 does not contact the inner wall of the cavity, and during the process of the lens barrel 1 going deep, the lens barrel 1 does not rub against the inner wall of the cavity, thereby making it difficult for the patient to feel pain, so that the patient no longer resists the treatment of cavity diseases, and improves the treatment efficiency. During the insertion process, the annular covering film 3 is continuously rolled outward, so that the annular elastic telescopic member 2 is continuously stretched to generate elastic force, so when the lens barrel 1 is pulled out, the retaining ring 4 is still pressed to remain motionless, and under the elastic force of the annular elastic telescopic member 2, the annular covering film 3 is continuously rolled inward, so that the annular covering film 3 will not remain in the patient's cavity after the lens barrel 1 is pulled out.

[0031] The annular elastic telescopic member 2 is detachably connected to the lens barrel 1; an annular plate 5 is fixedly connected to the top of the annular elastic telescopic member 2, an annular latch 6 is fixedly connected to the bottom of the annular plate 5, and an annular groove 7 matched with the annular latch 6 is provided on the top inner wall of the lens barrel 1; during operation, since the parts that are in direct contact with the patient's body are the annular covering film 3 and the retaining ring 4, the lens barrel 1 is not in direct contact with the patient, therefore, the lens barrel 1 and the elastic telescopic member are designed to be detachably connected so that the lens barrel 1 can be reused, and during installation, the annular latch 6 on the annular plate 5 is inserted into the annular groove 7 on the lens barrel 1 to achieve the installation of the elastic telescopic member.

[0032] The lens barrel 1, the annular elastic telescopic member 2, and the annular covering film 3 are all made of transparent materials; during operation, the condition of the inner wall of the cavity can be observed through the transparent lens barrel 1, the annular elastic telescopic member 2, and the annular covering film 3, which is convenient for medical staff to treat and examine.

[0033] The bottom of the lens barrel 1 has a chamfer 8; during operation, when the annular covering film 3 rolls outward from the bottom of the lens barrel 1, if the bottom of the lens barrel 1 has edges and corners, the rolling of the annular covering film 3 will not be smooth enough, and the annular covering film 3 may even be damaged, thereby causing harm to the patient's cavity. However, providing the chamfer 8 at the bottom of the lens barrel 1 can make the rolling of the annular covering film 3 smoother, thereby making the annular covering film 3 fit better when covering the inner wall of the cavity, and the patient feels better.

[0034] Both ends of the annular elastic telescopic member 2 are fixedly connected to the annular plate 5 and the annular covering film 3 respectively by hot melting. When working, due to the small size of this endoscope, the connection of the annular elastic telescopic member 2 through various connection structures easily occupies a larger space inside the lens barrel 1, thereby reducing the space for medical staff to inspect and treat the patient's cavity through the lens barrel 1. The use of hot melting to connect the annular elastic telescopic member 2 can make the connection of the annular elastic telescopic member 2 more stable and not occupy additional use space, which is convenient for medical staff to perform inspection and treatment operations.

[0035] The material of the annular elastic telescopic member 2 is high-elastic polyurethane; when working, the high-elastic polyurethane has good elasticity, is harmless to the human body, and is inexpensive, and is suitable for products that need to be replaced on a large scale.

[0036] A hand-held part 9 is also fixedly provided on the top of the lens barrel 1. When working, medical staff perform operations such as inspection and medication through the outer end of the lens barrel 1. Since the cavity is relatively private and direct contact is inconvenient, the hand-held part 9 can make it more convenient for medical staff to operate.

[0037] The material of the annular covering film 3 is polypropylene. When working, the diameter of the annular covering film 3 becomes larger after rolling from the inside to the outside of the lens barrel 1. Therefore, the annular covering film 3 needs to have good and uniform ductility. Polypropylene material has this property and is relatively low in price.

[0038] It should be noted that the connection mode of the annular elastic telescopic member 2 can also be the mode that the annular elastic telescopic member 2 is fixed on the lens barrel 1 by elastic pressing block etc. except the mode that annular latch 6 and annular groove 7 are docked on the annular plate 5, and any mode that can make the end of the annular elastic telescopic member 2 be fixedly connected with the inwall of the lens barrel 1 can all be applied at this.In addition, the material of the retaining ring 4 preferably adopts plastics or rubber etc. to have certain ductility, so that when the annular elastic telescopic member 2 and the annular covering film 3 are installed, the retaining ring 4 can be bent after passing through the lens barrel 1 to realize the annular covering film 3 and pass the lens barrel 1, and be convenient to the installation of the annular elastic telescopic member 2 and the annular covering film 3.

[0039] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
