Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a closed-endoscope. Background Art

[0002] An endoscope is a detection instrument integrating traditional optics, ergonomics, precision machinery, modern electronics, mathematics, software, etc. It has an image sensor, an optical lens, a light source for illumination, a mechanical device, etc. It can enter the stomach through the oral cavity or enter the body through other natural (artificial openings are also possible) orifices. With the endoscope, lesions that cannot be shown by X-rays can be seen, so it is very useful for doctors. For example, with the help of an endoscope, a doctor can observe ulcers or tumors in the stomach and thus formulate the best treatment plan.

[0003] The current endoscope is a medical device with both diagnostic and minimally invasive treatment functions. An endoscope generally includes an insertion part that can be inserted into a cavity and an operation part that can control the bending of the bending part in the insertion part. Among them, an imaging probe is provided on the head end seat of the insertion part, which can collect images in the cavity in real time for doctors to observe; an instrument channel is also provided through the insertion part, through which instruments such as sampling forceps can pass. One end of the instrument channel is communicated with a channel opening formed on the operation part, and the other end is communicated to the head end. During the process of endoscopic diagnosis and treatment, relevant treatment instruments can penetrate into the body cavity through the channel opening, be guided by the instrument channel, and then extend out from the head end to the body cavity for doctors to operate. For example, the prior art CN116831499A discloses an electronic endoscope, including: an operation component, and an insertion component and a connection component respectively arranged at both ends of the operation component; the insertion component includes an outer pipe and an inner pipe sleeved inside the outer pipe. The inner pipe has a medical channel, and a gap part is formed between the outer pipe and the inner pipe; one end of the insertion component is provided with a light-transmitting plate, and an image sensor and a light source component are installed on the light-transmitting plate. Both the image sensor and the light source component are connected with connection wires; among them, the connection wires sequentially pass through the gap part, the operation component and the connection component, and one end of the connection component is provided with an electrical connector for detachably connecting with a visual processing module. The use of photoelectric signals for image information transmission and the detachable replacement of the entire device have obvious advantages in the field of medical devices because the cost of the image sensor is relatively low, and it does not need to be cleaned for single use, reducing the maintenance and use costs, and improving the use safety of the device at the same time.

[0004] For the existing endoscope, doctors directly insert the insertion part of the endoscope into the human body for inspection and other operations, which is open during the use process, and thus has the following deficiencies: during the use of the endoscope, the non-inserted part is directly exposed to the outside and is easily contaminated, and there is a risk of infection for patients; after the endoscope is used, there are attachments on the insertion part, and it lacks protection, and there is a risk of leakage during the turnover process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] As Figures 1 - 5As shown in the figure, this embodiment provides a closed - type endoscope. This endoscope can enter the lungs or stomach through the mouth or enter the body through other natural orifices. With the endoscope, conditions that cannot be shown by X - rays can be seen, and at the same time, functions such as sputum suction, biopsy, drug administration, and flushing can be carried out through the working channel of the endoscope. The endoscope includes an operating component 1, an insertion component 2, a closed sleeve 3, and a closed head 4. The insertion component 2 is used to extend into the human body. One end of the insertion component 2 is connected to the operating component 1, and the other end of the insertion component 2 is in sliding fit with the closed head 4. The closed sleeve 3 is sleeved outside the insertion component 2, and both ends of the closed sleeve 3 are respectively connected to the operating component 1 and the closed head 4. The closed sleeve 3 can be folded and unfolded. The closed head 4 is provided with a sliding through - hole 5 for the insertion component 2 to enter and exit, and a cover 6 for blocking the sliding through - hole 5 is installed at one end of the closed head 4.

[0027] The closed sleeve 3 can be made of a transparent or semi - transparent film, and the thickness can be between 0.02 - 0.2 mm. The material is preferably a film with certain stretching properties, such as PU film and PE film, etc. The closed sleeve 3 has an unfolded state and a folded state. In the unfolded state, the closed sleeve 3 completely houses the insertion component 2 inside the closed sleeve 3, and the closed sleeve 3 provides a protective effect on the insertion component 2. In the folded state, a part of the insertion component 2 extends out of the closed sleeve 3 through the sliding through - hole 5 and then inserts into the human body for corresponding operations, and the other part of the insertion component 2 is housed inside the closed sleeve 3. The closed sleeve 3 protects the unused part of the insertion component 2 to avoid the unused part of the insertion component 2 being contaminated.

[0028] As Figure 2 and Figure 3 As shown in the figure, during the use of the endoscope, the extension length of the insertion component 2 is controlled by sliding the closed head 4. The part of the insertion component 2 that extends out of the closed sleeve 3 is used to insert into the human body for examination. The part of the insertion component 2 that does not extend out of the closed sleeve 3 is always inside the closed closed sleeve 3, improving the safety of the endoscope during use. After the endoscope is used, the insertion component 2 is completely housed inside the closed sleeve 3, providing isolation protection for the insertion component 2 and reducing the leakage risk of the endoscope during turnover. The endoscope of the present invention has good tightness, can avoid the endoscope being contaminated during use, thereby reducing the infection risk of patients. Moreover, after the endoscope is used, the closed sleeve 3 can provide isolation protection for the insertion component 2, effectively avoiding the risk of cross - infection during the turnover of the endoscope.

[0029] In a specific embodiment, as Figure 1As shown, the insertion component 2 includes a flexible endoscope tube 7, a lens tube connecting tube 8, a flexible sleeve 9, and a locking sleeve 10.

The lens tube channel is used for inserting the flexible endoscope tube 7, the instrument channel is used for the movement of the instrument, and the liquid inlet channel and the liquid outlet channel are respectively used for liquid inlet and liquid outlet. Since the lens tube channel, the instrument channel, the liquid inlet channel, and the liquid outlet channel are all prior arts, they will not be elaborated here. In the present invention, both the camera assembly 11 and the flexible endoscope tube 7 are prior arts. The camera assembly 11 and the flexible endoscope tube 7 adopt an integrated structure, and the end of the camera assembly 11 is a sealed structure. Therefore, only the outer wall needs to be disinfected after use.

[0031] In a specific embodiment, the end of the flexible sleeve 9 close to the lens tube connecting tube 8 is provided with an insertion end, and the insertion end is provided with a blocking ring piece 12. The insertion end of the flexible sleeve 9 is inserted into the lens tube connecting tube 8, and the blocking ring piece 12 abuts against the end of the lens tube connecting tube 8. The flexible sleeve 9 and the lens tube connecting tube 8 are inserted into each other and fixed through the locking sleeve 10, which is convenient for the assembly of the flexible sleeve 9 and the lens tube connecting tube 8. In order to increase the sealing performance between the flexible sleeve 9 and the lens tube connecting tube 8, a rubber gasket 14 is arranged between the flexible sleeve 9 and the lens tube connecting tube 8.

[0032] Among them, at least two locking grooves 13 are arranged on the surface of the lens tube connecting tube 8, and locking buckles adapted to the locking grooves 13 are arranged on the inner side of the locking sleeve 10. Preferably, two locking grooves 13 are symmetrically arranged on the surface of the lens tube connecting tube 8, and two locking buckles are correspondingly arranged on the inner side of the locking sleeve 10. The two locking buckles and the two locking grooves 13 cooperate with each other to fix the flexible sleeve 9 and the lens tube connecting tube 8 together.

[0033] Specifically, the locking groove 13 includes an entry section, a sliding section and a locking section, the entry section, the sliding section and the locking section are connected in sequence, one end of the entry section extends along the axial direction of the mirror tube connecting tube 8 to the end of the mirror tube connecting tube 8, the sliding section is arranged in an arc shape along the surface of the mirror tube connecting tube 8, and the locking section is arranged along the axial direction of the mirror tube connecting tube 8. The locking sleeve 10 is sleeved on the mirror tube connecting tube 8, the locking buckle slides along the entry section to the sliding section, and then the locking buckle is rotated half a circle or a certain angle, so that the locking buckle slides along the sliding section to the locking section, and finally the locking buckle stops at the locking section, and the flexible sleeve 9 is fixed to the mirror tube connecting tube 8.

[0034] like Figure 4 As shown, in a specific embodiment, a scraping mechanism 15 is provided inside the sealed head 4, and the scraping mechanism 15 is used to scrape off the attachments on the surface of the insertion component 2. After the endoscope is used, the scraping mechanism 15 is used to scrape off the attachments on the surface of the insertion component 2, so that the attachments remain inside the sealed head 4.

[0035] like Figure 5 As shown, the scraping mechanism 15 includes at least two scraping blades 16, the scraping blades 16 are provided with notches, all the scraping blades 16 are arranged in an annular structure, and the notches of each scraping blade 16 are interconnected and combined to form a scraping hole 17 adapted to the insertion component 2. Preferably, the inner wall of the sliding through hole 5 is provided with an annular storage groove 18, and the scraping blade 16 is arranged on the inner wall of the annular storage groove 18. The scraping mechanism 15 includes four scraping blades 16, and the four scraping blades 16 are arranged on the inner wall of the annular storage groove 18. The center position of the four scraping blades 16 is the scraping hole 17 for the movement of the insertion component 2. The scraping blades 16 do not affect the normal movement of the insertion component 2. At the same time, the scraping blades 16 can scrape the attachments on the surface of the insertion component 2 and leave them in the annular storage groove 18. The sliding through hole 5 is closed by the cover 6 to prevent the attachments from leaking.

[0036] In a specific embodiment, Figure 4 As shown, the cover 6 includes a cover body 19, and a sealing boss 20 is provided on one side of the cover body 19. The sealing boss 20 is clamped in the sliding through hole 5 to close the sliding through hole 5 to prevent the insertion component 2 from being contaminated and the attachments from leaking. The cover 6 blocks the sliding through hole 5 before the endoscope is used to prevent the flexible sleeve 9 from being contaminated; the cover 6 needs to be disassembled when the endoscope is used so that the flexible sleeve 9 can extend out of the sliding through hole 5. The cover 6 blocks the sliding through hole 5 before the endoscope is used to prevent the attachments from leaking.

[0037] When the endoscope of the present invention is not in use, the sealed sleeve 3 is in an unfolded state, the flexible sleeve 9 is located on the inner side of the sealed sleeve 3, and one end of the flexible sleeve 9 is located in the sliding through hole 5 of the sealed head 4, and the cover 6 blocks the end of the sliding through hole 5, so that the insertion component 2 can be protected and the insertion component 2 is contaminated. When the endoscope is in use, the sealed sleeve 3 is in a folded state, that is, the cover 6 is removed, and the sealed head 4 is slid along the flexible sleeve 9, so that the sealed sleeve 3 is gradually folded, and one end of the flexible sleeve 9 extends out of the sealed head 4, so that a part of the flexible sleeve 9 is exposed for the doctor to diagnose and treat the patient, and the other part of the flexible sleeve 9 is inside the sealed sleeve 3 to avoid the uninserted part from being contaminated, thereby improving the safety of the endoscope during use. After the endoscope is used, the sealed sleeve 3 is in the expanded state, and the sealed head 4 is slid along the flexible sleeve 9 to gradually expand the sealed sleeve 3, and the sealed sleeve 3 covers the flexible sleeve 9. At the same time, the scraper 16 slides relative to the flexible sleeve 9, and the scraper 16 can scrape off the attachments on the surface of the insertion component 2 and leave them in the annular storage groove 18. The sliding through hole 5 is closed with the cover 6 to prevent the attachments from leaking; then the locking sleeve 10 is rotated to separate the mirror tube connecting tube 8 and the flexible sleeve 9. After the flexible endoscope tube 7 is pulled out, the flexible sleeve 9 can be directly discarded, and the flexible endoscope tube 7 is not contaminated and can be simply disinfected.
