Abstract
The utility model discloses a kind of pouch suspensory retractors, including retractor head, drag hook handle, suspention line and suture needle, retractor head uses flexible intraocular biocompatible materials, one end is connected on hollow drag hook handle, form fish hook formation, it suspends line in midair and uses polypropylene material, one end passes through drag hook handle and is connected to retractor head one end, and the other end is connected to suture needle tail end.The utility model is hooked in pouch using retractor head, and the suspention line for connecting retractor head is sewn onto scleral walls by suture needle, to realize the fixation of pouch, this passes through retractor head, suspention line artificial suspensorium similar with the pouch Suspending fixation device that suture needle is constituted, the fixed lens capsule bag of the suspensorium being broken is substituted, structure is simple, low in cost, easy to operate, use is safer.
Description
Technical field
The utility model relates to a kind of pouch suspensory retractors, belong to technical field of medical equipment.
Background technique
Apparatus suspensorius lentis caused by wound or congenital anomaly is abnormal in the past cataract surgery, less than 1/2
Dislocation can be used capsular tension ring and pouch supported to operate in order to artificial lens implant surgery, also feasible artificial lens or pouch
Sling operation.The former 2,000 yuan of price or so, price is higher, is only capable of helping for the even tension of suspensorium to be distributed, can not
It is additional to increase the fixed pouch of tension, and be only capable of operating in pouch, operating space is limited, and the suspensorium detachment greater than 1/2 is not
It is suitble to use；The latter is cumbersome, and technical requirements difficulty is high, and postoperative complication is more, is unfavorable for clinical development, there are biggish
Medical hidden danger.
Summary of the invention
Technical problem to be solved by the utility model is: a kind of pouch suspensory retractor is provided, it cannot to solve the prior art
The technical operation that the suspensorium detachment greater than 1/2 of processing and suspensorium detachment material less than 1/2 are likely to occur is complicated,
Difficulty is high, complication is more, less effective, clinical development difficulty, expensive problem, can solve most of lens-dislocation disease
The treatment difficult point of people.
The technical solution that the utility model is taken are as follows: a kind of pouch suspensory retractor, including retractor head, drag hook handle, suspention line
And suture needle, retractor head use flexible intraocular biocompatible materials, one end is connected on hollow drag hook handle, is formed
Fish hook formation, suspention line use polypropylene material, and one end passes through drag hook handle and is connected to retractor head one end, other end connection
To suture needle tail end.
Preferably, above-mentioned retractor head uses PMMA or polypropylene material.
Preferably, it is connected as being detachably connected between above-mentioned retractor head and drag hook handle.
Preferably, above-mentioned retractor head length 3mm, hook inner width 1mm.
Preferably, above-mentioned suspention line length is 10-20cm.
Preferably, above-mentioned suture needle uses stainless steel material, and the length is 3mm.
The utility model has the beneficial effects that compared with prior art, the utility model is hooked in pouch using retractor head,
And the suspention line for connecting retractor head is sewn onto scleral walls by suture needle, to realize the fixation of pouch, should by retractor head,
It suspends line artificial suspensorium similar with the pouch Suspending fixation device that suture needle is constituted in midair, it is crystalline to substitute the suspensorium fixation being broken
Somatocyst bag, structure is simple, low in cost, easy to operate, previously commonly uses capsular tension ring, but capsular tension ring is only capable of making remnants'
Suspensorium uniform force and cannot reinforce, fix row cataract operation and crystalline substance after cyst membrane in the retractor head using the utility model
Body implantation is safer, fixes loose or dialysis suspensorium using drag hook, can mitigate the tension of opposite side suspensorium,
The drawing to abnormal suspensorium can be mitigated in surgical procedure, the detachment of abnormal suspensorium or detachment is avoided to expand, so as to
Prevent the exacerbation of suspensorium detachment, intraocular tolerant loss can be reduced, artificial lens is enable to be placed in pouch, it is inclined to reduce crystalline lens
The possibility of position avoids or alleviates the complication such as suspensorium is broken caused Prevention and treatment, artificial lens cannot be implanted into and occurs,
Security risk is effectively eliminated, the suspensorium detachment greater than 1/2 that efficiently solves that the prior art cannot handle and less than 1/2
The technical operation that suspensorium detachment material is likely to occur is complicated, difficulty is high, complication is more, less effective, clinic carry out difficulty,
Expensive problem, capsular hooks can then solve the treatment difficult point of most of lens-dislocation patient, also can be used as iris/capsule
Film drag hook temporarily uses, be suitable for medical field promote and apply, the utility model also have structure it is simple, it is at low cost, using dimension
Protect convenient and efficient feature.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1- retractor head, 2- drag hook handle, 3- suspention line, 4- suture needle.
Specific embodiment
With reference to the accompanying drawing and the utility model is described further in specific embodiment.
Embodiment 1: as shown in Figure 1, a kind of pouch suspensory retractor, including retractor head 1, drag hook handle 2, suspention line 3 and suture needle
4, retractor head 1 uses flexible intraocular biocompatible materials, and one end is connected on hollow drag hook handle 2, forms fish
Hook formation, suspention line 3 use polypropylene material, and one end passes through drag hook handle 2 and is connected to 1 one end of retractor head, and the other end connects
It is connected to 4 tail end of suture needle.
Preferably, above-mentioned retractor head 1 uses PMMA or polypropylene material, and elasticity is good, intraocular good biocompatibility, avoids hard
It is pulled caused by drag hook.
Preferably, it is connected as being detachably connected between above-mentioned retractor head 1 and drag hook handle 2, is detachably connected as being threadedly coupled, fill
Tear open it is convenient and efficient, it is easy to use.
Preferably, above-mentioned 1 length 3mm of retractor head, hook inner width 1mm can satisfy and be articulated in pouch, excessive to will cause sky
Between it is limited, it is not easy to operate, it is too small will lead to mounting it is unreliable.
Preferably, above-mentioned suspention line 3 uses polypropylene material, and intraocular good biocompatibility should not intraocularly degrade, length
For 10-20cm, adapts to suture and require, it is too long to will lead to influence surgical procedure, it is too short and it is impossible to meet sutures to require.
