Detailed Description

In the description of the present invention, it should be understood that the terms "upper", "lower", "inner", "outer", "near", "far", and the like indicate orientations or positional relationships based on orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.

Referring to fig. 1 and 2, the present embodiment provides a double-lumen endoscope sheath, which includes a sleeve 1, a sealing valve 2, a gas valve 3, and an operation tube 5;

the sleeve 1 defines an internal channel 100 extending from a proximal end to a distal end, the sleeve 1 has a socket 101 at a proximal end, the distal end of the sleeve is sealed by a sealing member 6, at least a part of the sealing member is arranged to be transparent for observation by an endoscope, and further, a sealing valve is arranged inside the sleeve, so that the sealing valve and the sealing member cooperate to seal the internal channel to facilitate the suction and inflation operation of the internal channel;

an operating tube 5 is arranged through the sleeve 1 from the proximal end to the distal end in a sealing way, and the remaining space of the internal channel 100 after the operating tube is accommodated is suitable for an endoscope to enter the internal channel through the socket 100; the proximal end of the operating tube is provided with a proximal tube section 51 extending out of the sleeve, the distal end of the operating tube is provided with a distal tube section 52 extending out of the operating tube, and the upper tube section and the distal tube section are respectively provided with an upper suction port 510 and a lower suction port 520; firstly, the operating tube penetrates through the sleeve in a sealing manner to ensure the tightness of the internal channel; specifically, the handling tube may be hermetically bonded or heat-bonded to the perforated peripheral edge of the sleeve, or the like; the introduction of the operation tube can avoid the intervention of external instruments such as a suction sputum tube and the like after the endoscope is inserted, and the problem that the external instruments are inconvenient to intervene due to the narrow air passage is solved.

The key point is that the remaining space of the internal channel 100 after the operating tube 5 is received is required to be suitable for an endoscope to enter the internal channel through the socket 100, at least the part of the sleeve 1 used for entering the human body is made of a soft material, and an air valve 3 is arranged on the near side of the sleeve 1, namely the operating side of a doctor, and is used for performing air suction or inflation operation on the internal channel 100; after the endoscope rod of the endoscope is inserted, the sealed internal channel is pumped so that the soft sleeve section is tightly attached to the endoscope, the radial size of the endoscope and the endoscope sleeve which are inserted into the cavity of a patient is reduced, and the observation visual field is clearer; therefore the utility model provides a sealing valve is suitable for when the endoscope is inserted or before inserting and insert the leakproofness that all need guarantee the inside passage after, structure implementation about the sealing valve, the utility model provides a some implementation: the sealing valve is made of elastic polymer materials with reversible deformation, and a valve port with the diameter smaller than that of the endoscope rod is arranged on the sealing valve 2; specifically, for example, the present embodiment employs a conical rubber sealing valve, and the sealing valve 2 has a valve port 21 which is in sealing fit with the stem of the endoscope, so that when the endoscope enters the sleeve through the valve port, the internal channel is in a sealed state; and when the endoscope is inserted, the endoscope rod is tightly jointed with the valve port, so that the sealing performance of the internal channel is ensured.

Because the mirror sleeve provided by the embodiment is disposable, the disinfection step after use is avoided, and the cost is saved.

In the present embodiment, the sleeve 1 comprises a flared section 13 located proximally, a narrowed section 11 located distally, and a tapered section 12 formed at the transition between the flared section 13 and the narrowed section 11, the flared section 13 being adapted to snap-fit with the handle end of the endoscope; the sealing valve 2 is arranged between the flaring section 13 and the conical section 12, and the operating pipe 3 is arranged to penetrate through the narrow section 11 in a sealing manner;

the flaring section 13 is a hard piece, the narrow opening section 11 and the conical section 12 are soft pieces, and the air valve 3 is arranged at the conical section 12, so that the narrow opening section and the conical section can expand and bulge or contract under the action of the air valve and the air pumping and inflating pump.

In this embodiment, the sealing member includes a transparent lens disposed at the distal end of the sleeve, the transparent lens not obstructing the view of the endoscope while ensuring that the internal channel is in a sealed state; in particular, the distal section 52 and the transparent lens are connected together such that the distal section 52 and the transparent lens are disposed as a unit at the distal end of the sleeve 1.

Specifically, the lower suction port 520 forms an oblique port disposed away from the seal, which facilitates insertion into the body.

Specifically, the sleeve is integrally made of a transparent film piece.

In addition, the sleeve 1 and the operating tube 5 are firmly connected by a connecting piece.

During the use, aerify the pneumatic valve earlier, make narrow mouthful section and conic section swell, stretch into the smooth flaring section socket of following of endoscope, the perfect lock of flaring section and endoscope handle end, the endoscope passes the endoscope passageway after stretching into and reachs transparent lens department smoothly, airs this moment to the pneumatic valve for telescopic narrow mouthful section perfect laminating endoscope, corresponds the operation through the control tube when necessary: sputum suction, local hemostasis, etc.

Further, the operation pipe is a hose
