Description

A kind of medical lacrimal passage visible probe

Technical field

The utility model is related to a kind of medical surgical instruments, and in particular to a kind of medical lacrimal passage visible probe.

Background technology

Lacrimal is the pipeline of lacrimal drainage, including upper and lower lacrimal and tear manifold, connects puncta and lachrymal sac.Wound Property laceration of lacrimal canaliculus is one of common acute disease of ophthalmology, and upper inferior lacrimal canaliculus often merges lid injury, if not in time after damage Surgical stapling reparation is connected or is dealt with improperly, can not only be caused endocanthion angle lopsided, be influenced beauty, and there is also more serious Excessive tear influences quality of life.

It coincide for laceration of lacrimal canaliculus, at present frequently with anesthesia epidural catheter, specific method is the tear using hard The probing of road probing needle elder generation is intended to the identical broken ends of fractured bone and entire lacrimal passage, and confirming to coincide through probing needle injection brine, errorless (brine can enter Nasal cavity and pars oralis pharyngis) after, lacrimal passage probing needle is extracted, then lacrimal passage is inserted on the roads epidural catheter Xun Yuan, coincide the broken ends of fractured bone, and by tear The outer one end indwelling of dot is in outside lacrimal passage, fixing on the skin, generally through 3 months, is taken out after the healing of the lacrimal passage broken ends of fractured bone.This operation In, it completes to coincide in two steps and epidural catheter nature brings many inconvenience to operation, cause the pain that patient is additional, and Increase the risk of postoperative complication：1. the channel of lacrimal passage and non-direct type, respectively there are two bending at margo palpebrae and the nasion, and it is curved Dog-ear degree is big, is inserted into conduit just easy to operation, and the finite stiffness of epidural catheter that need to have a certain degree of hardness, bending place usually Dynamics is inadequate, it is difficult to be inserted into, as soundd out repeatedly, easily cause Lacrimal path damage；2. judging to depend on lacrimal passage whether lacrimal passage correctly coincide The result of flushing judges, and irrigation of lacrimal passage needs to use lacrimal passage probing needle, can not judge catheter position after being inserted into epidural catheter It is whether correct；3. during epidural catheter indwelling, generally stretch out in outside lacrimal point, delicate fragility is organized at lacrimal point, at this time dura mater The hardness of outer catheter shows excessive again, be easy to cause lacrimal point tearing.

It is that brine is injected using probing needle to confirm whether kiss in conclusion judging to coincide whether succeed in the prior art Work(is synthesized, but during actual clinical, many patient with operation need general anesthesia, as children, whole body condition are not resistant to local anaesthesia Person, irritability person etc. or the patient of confusing communication, such as deaf-mute, language obstacle person, these patients cannot be to pars oralis pharyngis It is no to have liquid by giving a response and describing, it enables patient that can not judge that lacrimal passage coincide and whether succeeds, or even in patients with general anesthesia, injection Brine may cause cough of choking, and cause danger.

Invention content

The purpose of this utility model is to overcome above-mentioned the shortcomings of the prior art places, and provide a kind of medical tear Road visible probe, its application easy to use, easy to operate, easy to promote large-scale.

The technical solution adopted in the utility model is：A kind of medical lacrimal passage visible probe, including needle body, before the needle body End connects transmittance section by fastener, and the transmittance section front end is equipped with protective cover, and the needle rear end is equipped with handle part, described Handle part be equipped with feeding opening；It is the double-deck ring cavity structure inside the needle body, ring cavity structure includes inner cavity and exocoel, described Exocoel be medicinal liquid cavity, the medicinal liquid cavity be equipped with the external world perforation medicine outlet, the inner cavity be equipped with optical fiber, institute The optical fiber front end stated is located at transmittance section, and the optical fiber rear end connects fiber alignment head, and the fiber alignment head passes through limit Block is fixed on optical fiber flange adapter, and the fiber alignment head of the optical fiber flange adapter other end connects monitor, institute The monitor stated be equipped with display screen, the display screen lower end be equipped with control key, the monitor tail portion be equipped with battery and Charge port.

The protective cover end is smooth hemispherical.

The inner cavity is sealed construction.

The needle body is alloy body.

Sealing-plug is equipped at the feeding opening.

The utility model has the beneficial effects that：Can be correct by the cooperation of optical fiber and monitor, and accurately insert Into in lacrimal passage, reduce the risk of operation and the pain of patient, fiber alignment head and optical fiber flange adapter may be implemented probe with Space is saved in the assembly and disassembly of monitor, with when assemble, the disinfection of rear disassembling cleaning is finished, and convenient for storage, into medicine Mouth and medicine outlet, which realize, to reduce the access times of probe simultaneously by the lacrimal passage effect capable of washing again of probe i.e. lacrimal passage probing Alleviate the pain of patient.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model.

Specific implementation mode
