Description
Technical Field
The utility model relates to an auxiliary tool for a medical endoscope, in particular to a laser optical fiber protection device.
Background
Currently, a medical endoscope mainly includes an insertion portion, an operation portion, and a light guide portion, and a forceps channel for guiding insertion of a surgical instrument is installed in the operation portion. Some procedures may be performed using an endoscope and a laser, the laser fiber of the endoscope being capable of delivering a laser beam to cauterize a neoplasm or tumor and seal a bleeding blood vessel. The front end of the laser fiber extending into the forceps channel is sharp, so that the endoscope forceps channel is easy to scratch, the length of the laser fiber is long, the laser fiber is easy to bend and damage in the using process, and in addition, the laser fiber can carbonize tissues and generate eschar in the using process, so that the operation visual field is influenced.
Disclosure of Invention
An object of the utility model is to overcome the defect that exists among the prior art, provide one kind and can protect laser fiber, can also protect the pincers way, can carry out water injection or injection operation under the condition that does not withdraw laser fiber, shorten operating time's laser fiber protection device greatly.
The utility model discloses a realize like this: a laser optical fiber protection device comprises a protection pipe sleeve used for penetrating a laser optical fiber, wherein a fixer is arranged at the tail end of the protection pipe sleeve, and scales are arranged on the outer surface of the front end of the protection pipe sleeve; the tail part of the protective pipe sleeve is provided with a short pipe which is opened laterally, the fixer comprises a shell, a fixing piece, a screw rod and a rotary handle, an optical fiber channel communicated with the inside of the protective pipe sleeve is arranged in the shell, the screw rod vertically penetrates through the side wall of the shell and is connected with the fixing piece in the optical fiber channel, and the rotary handle is connected with the screw rod outside the shell; the screw is connected with the shell through threads; the inner side surface of the fixing piece is provided with an anti-slip layer.
The tail end of the side-opening short pipe is provided with a sealing cover.
The maximum scale range of the scales is 1-5 cm.
The length of the protective pipe sleeve is 90-110 cm.
The diameter of the optical fiber channel is 0.17-0.19 cm.
The protective pipe sleeve is a transparent hose.
The utility model has the advantages that: the laser optical fiber is protected by the protective tube sleeve, the service life of the laser optical fiber is prolonged, and meanwhile, the damage of the laser light to the endoscope clamping channel is avoided; through the short pipe with the side opening, under the condition that the laser optical fiber is not withdrawn, water injection or medicine injection operation can be carried out on the inner part of the protective pipe sleeve through the short pipe with the side opening, the phenomenon that the operation visual field is influenced due to eschar generated by tissue carbonization is prevented, and the operation time is greatly shortened.

Fig. 1 is a schematic view of the internal structure of the present invention.
Wherein: 1. a laser fiber; 2. a protective pipe sleeve; 3. a holder; 4. calibration; 5. a short pipe is opened on the side; 6. a housing; 7. a fixing sheet; 8. a screw; 9. rotating the handle; 10. a fiber channel; 11. and (7) sealing the cover.
Detailed Description
According to fig. 1, the present invention comprises a protective sleeve 2 for passing a laser fiber 1, said protective sleeve 2 being a transparent hose. The tail end of the protective pipe sleeve 2 is provided with a fixer 3, and the outer surface of the front end of the protective pipe sleeve 2 is provided with scales 4; the maximum scale range of the scale 4 is 1-5 cm. The tail part of the protective pipe sleeve 2 is provided with a short pipe 5 which is opened at the side, the fixer 3 comprises a shell 6, a fixing piece 7, a screw 8 and a rotary handle 9, an optical fiber channel 10 communicated with the interior of the protective pipe sleeve 2 is arranged in the shell 6, the screw 8 vertically penetrates through the side wall of the shell 6 and is connected with the fixing piece 7 in the optical fiber channel 10, and the rotary handle 9 is connected with the screw 8 outside the shell 6; the screw 8 is connected with the shell 6 through threads; the inner side surface of the fixing piece 7 is provided with an anti-slip layer, and the anti-slip layer is preferably a rubber layer. The tail end of the side-opening short pipe 5 is provided with a sealing cover 11. The length of the protective pipe sleeve 2 is 90-110 cm, and preferably 100 cm. The diameter of the optical fiber channel 10 is 0.17-0.19 cm, and preferably 0.18 cm.
The utility model discloses during the use, pass fibre channel 10 and the protection tube housing 2 of fixer 3 with laser fiber 1 in proper order, through scale 4 can clearly judge the position of laser fiber 1 in protection tube housing 2. The position of the laser fiber 1 in the protective sleeve 2 is moved, so that the front end of the laser fiber 1 is hidden in the protective sleeve 2, the laser fiber is fixed through the fixer 3, then the protective sleeve 2 and the laser fiber 1 are placed in an endoscope clamping path and observed, when the front end of the laser fiber 1 reaches a focus position, the screw rod 8 and the fixing piece 7 are driven to retreat and loosen through rotating the rotary handle 9, so that the fiber channel 10 is widened, the front end of the laser fiber 1 is pushed out from the protective sleeve 2 by the handle at the rear end of the laser fiber 1, then the rotary handle 9 is screwed, so that the laser fiber 1 is fixed by the fixing piece 7, and laser surgery can be carried out. If the mirror surface is fuzzy in the operation or the wound surface is bleeding, the laser optical fiber 1 does not need to be taken out, the sealing cover 11 is directly opened to inject water and medicine through the side opening short pipe 5, after the operation is finished, the laser optical fiber 1 is loosened through rotating the handle 9, the front end of the laser optical fiber 1 is pulled back into the protective pipe sleeve 2 again to be hidden, then the protective pipe sleeve 2 and the laser optical fiber 1 are taken out from the endoscope channel together, and the smooth operation is ensured.
