Description
Technical field
The present invention relates to medical instruments field, more particularly, to fracture lacrimal canalicular anastomosis and lacrimal stent is synchronously implanted into
Operation device and its probe.
Background technology
Eye traumas is the common disease of ophthalmology, and according to documents and materials, eye traumas accounts for ophthalmology and is in hospital the 1/3 of total number of persons,
It is the first blinding factor in ophthalmology inpatient, accounts for the 5%-10% of whole-body trauma disease.Traumatic canaliculus disruption is eye
The common complication of wound, because wound is irregular, local organization reaction oedema, wound oozing of blood, local anesthetic are injected, tear is small
Pipe fracture port is located at the various factors such as tissue deep, causes the anastomosis operation mortality of lacrimal higher.In turn result in patient's length
Phase epiphora symptom, has had a strong impact on quality of life.
Current conventional therapeutic modality includes：
(1) single-handedly implantation：Unilateral adopted pipe implantation is generally used for, because conduit is soft, operating difficulties, it is difficult to which conduit is implanted into
Precalculated position, and postoperative conduit extrusion rate is higher.
(2) pigtail type probe：It is the current operation method for being widely accepted and using.Predominantly visited using a kind of annular
Pin enters from the puncta for being broken lacrimal offside, is passed after tear house steward transfers from fracture lacrimal near-end, reaches detection
Fracture end and the dual purpose of conduit implantation.Due to the stainless steel that the pigtail type probe that uses at present is hard quality, typically
Elastic deformation will not be produced, easily causes Lacrimal path damage and via formation；Secondly end of probe need to leave threading pin hole so that head
Portion is bigger than normal, easily causes lacrimal passage hard force expansion damage or is not easily accessible lacrimal passage；Furthermore using the preset lacrimal passage suture of probe, by stitching
Because the presence of knot can become difficult when line traction conduit enters lacrimal passage, and organizing the case management of deep laceration of lacrimal canaliculus just
It is more intractable.
At present, through searching document, a kind of newest disclosed operation device (CN for being used for identical fracture lacrimal
203736381 U) air and liquid injected to confirm free fracture end by lacrimal passage, reuse magneticaction guiding Magnetic force ball-
Suture-conduit passes from lacrimal-tear house steward-complete lacrimal is broken, and reaches the purpose for being implanted into adopted pipe.The method operates
It is more complicated, and can not still avoid needing fracture end to position and require that conduit pulls entrance from laceration of lacrimal canaliculus end suture, therefore
To the case of organizing deep laceration of lacrimal canaliculus, there is also the unsuccessful risk of performing the operation.
In summary various therapeutic modalities, it is based on to be accurately positioned laceration of lacrimal canaliculus end in advance, and wants derivation
Pipe from laceration of lacrimal canaliculus end can be at least once accurate suture draw implantation, this is current nasolacrimal anastomosis success
Committed step.Fracture end location technology in Present clinical use, including Dye Injections method, thick substances injection and liquid note
Penetrate method etc. and there may be the various deficiencies such as pollution, conditionality, operating difficulties；And conduit is from the accurate suture in laceration of lacrimal canaliculus end
It is pulled into, given surgical effect can not be usually obtained in the cases such as serious, the surgical field of view oozing of blood obstruction of local organization swelling,
Even can not smoothly it enter in deep laceration of lacrimal canaliculus case is organized.
In addition, lacrimal puts pipe and pulls out the time and is generally 3-6 months at present, but easily occur in tube drawing or after tube drawing
Complication, including difficulty in decannulation (23%), nasal cavity stump hide (4.4%), drainage tube comes off (2.7%), lacrimal passage support tube thorn
Broken lacrimal caruncle (5.9%), stenosis of lacrimal canaliculus (6.2%), nasolacrimal passage obliteration cause flushing to backflow (4.4%)；Lacrimal point cleaves or lacrimal
Tear (4.8%), lacrimal point is scorching, canaliculitis and dacryocystitis (3.1%), granulation breed (11.1%), and difficulty in decannulation or the broken ends of fractured bone are residual
(5.4%) is stayed, via formation (0.9%), and if occurring Secondary cases obstruction of lacrimal passage after tube drawing, even I phases lacrimal is performed the operation
Success, which coincide, will also become meaningless.To find out its cause, caused by the scar obstruction lacrimal passage mainly formed after broken ends of fractured bone healing, also may be used
There can be the damage that traction knot or hard apparatus are expanded in art to whole lacrimal passage interior wall tissue, cause tube wall thickening, adhesion, increasing
Life, even collapse.
At present, put that pipe mode puts pipe including single lacrimal and double lacrimal annulars put pipe；Putting tube material includes plastics, silicon
Glue, and novel degradable material etc..And in clinical practice, that also complies with one's wishes not to the utmost below is local to be modified.
(1) pipe mode is put：
Though single lacrimal, which puts pipe, is easy to later stage tube drawing, easily slipped from lacrimal, fixed relative difficulty.
Leibovitch et al. puts pipe using the mono- lacrimals of Mini-Monoka, and near-end is fixed on lacrimal point by grappling plug, partly solved
State shortcoming.
Double lacrimal annulars are put pipe and are substantially increased compared to the stability of single Lacrimal passage tube, but how the end line knot that coincide is handled
It is a great problem.Knot is rotated into lacrimal to nasolacrimal duct by most patient, as a result causes further damage of the knot to tube chamber
Wound.And the justice pipe for being exposed to interpalpebral zone can also cause many discomforts of patient, such as：Turned up in foreign body sensation, puncta, secretion adhesion
Aggregation, influence outward appearance etc..Have been reported that to burn two free-ends and be stuck in puncta in " 7 " type, form the implantation of inverted " C " type, but still have
Stump is present in interpalpebral zone, fails thoroughly to solve the above problems.
Also, either it is above-mentioned which kind of put pipe mode, be required for making tube drawing processing after the 3-6 months, it is possible to again result in
While Lacrimal path damage, because losing lacrimal passage supporter, it is likely to occur narrow in lacrimal, especially lacrimal occurs in some cases
Hyperplasia at end-to-end anastomosis, and then obstruction of lacrimal passage.
