Description
Technical field
This utility model belongs to micro-ophthalmology and microsurgical technique field, is specifically related to a kind of micro-needle holder of elbow band shears.
Background technology
The surgical operation step that adopts suture needle and suture to sew up is the necessary link that most of microsurgerys all have.When microsurgical procedure, be common in clinically in the intraocular surgery sclera, cornea, bulbar conjunctiva, the stitching of lacrimal ductule tissue when iris even ocular injury also often will be used fiber suturing skill coincide little blood vessel and nervelet in vascular surgery and neurosurgery in addition.Traditional way, two tissues that separate are passed in the suture needle that will use micro-needle holder to grip band wire during stitching earlier respectively, tighten up closed these two tissues by the knotting (common 3 knots) of suture then, be exchanged into micro-shears afterwards again, prune at the toe-in root.Recent decades, use micro-shears the cutting off and the pruning of toe-in of back suture of tiing a knot always.Because organizing of being sewn is meticulousr often and softish, it is particularly important at this moment not have any tensile trimming, has tensile tractive to tend to produce dissection, may cause tissue injury and toe-in to get loose.
Usually during micro suture, often needing many needlework knots needs to prune, if the trained assistant of neither one assists trimming, will be carried out the operation technique of whole steps by a people, this is more common when emergency treatment, the operation if a people undergos surgery, so just have repeatedly needle holder and the exchange between shears, the time that this wound that not only increases exposes, thus the time of operation prolonged, but also increased the probability of apparatus contamination and wound pollution.In addition in emergency circumstances at some, plant during as penetrating keratoplasty sheet and plant bed to when sewing up, the tolerant pressure of ophthalmic is often higher, the not good trouble eye of myosis before artificial intraocular lenses's eye and art, if do not plant the stitching of sheet fast, artificial intraocular lenses and crystalline lens or vitreous body are just deviate from easily, will cause operative failure, will make eyeball be difficult to keep if explosive choroid massive hemorrhage takes place.And for example when the emergency treatment eyeball rupture is hindered, it is auxiliary often not have the assistant, and need sew up the wound of cornea or sclera as early as possible, so as not to tolerant deviate from of ophthalmic massive hemorrhage takes place in incarceration and the ball.
When the suture operation of non-micrurgic conventional skin breach, existing how tame patent has designed the needle holder of band shears, the more typical example such as the patent No. are that the surgery of ZL89210540.2 is that the surgery of ZL200720103454.7 is with integral type band shears needle holder with the one band shears needle holder and the patent No., these two parts design cleverly can be when trimming, needn't needle holder and shears between carry out frequent substitution, and avoided the shears knife edge in the sewing process to expose being caused iatrogenicly organize the cutting damage.In clinical ophthalmology work, the band shears needle holder of introducing in a kind of outer ocular operation is easily and effectively also arranged, when common eyelid operation and conjunctival operation, can singlely fast finish the series of sutures operation, when having saved operating time greatly, the generation of potential complication be will avoid or reduce to greatest extent, thereby patient and all satisfied surgical state of doctor reached.For being fit to Ophthalimic microsurgery, also designed the micro-needle holder of band shears by the people, the patent No. is the micro-needle holder with micro-shears of ZL 200720021455.7, this needle holder shears portion protrudes, the straight peen design.But the needle holder of the band shears that uses clinically is the straight peen design at present, this when being designed for outer ocular operation operation be very freely, but often need accurate undamaged stitching and accurate toe-in to prune during microsurgery, this just requires patient's hand to move little as far as possible or does not move, if still adopt the micro-needle holder of the band shears of straight peen design, then must patient's hand do moving by a relatively large margin, this not only unfavorable accurate fast stitching, but also increased the iatrogenic risk of bringing greatly owing to the apparatus moving range when sewing up.
Summary of the invention
The purpose of this utility model is to provide a kind of micro-needle holder of elbow band shears.
The micro-needle holder of the elbow band shears that the utility model proposes, hold leaf 1 on the needle body by micro-, micro-ly hold needle body inferior lobe 2, leaf 3 on the microscissors cutter hub, microscissors cutter hub inferior lobe 4, screw 5, leaf 6 on the hand-held caliper, hand-held caliper inferior lobe 7, leaf 8 on the spring leaf, spring leaf inferior lobe 9, fixing rivet 10 and spring leaf bayonet socket 11 are formed, wherein, micro-ly hold leaf 1 on the needle body, on the microscissors cutter hub on leaf 3 and the hand-held caliper leaf 6 connect to form one successively, micro-ly hold needle body inferior lobe 2, microscissors cutter hub inferior lobe 4 and hand-held caliper inferior lobe 7 connect to form one successively, leaf 6 junctions on leaf 3 and the hand-held caliper on the microscissors cutter hub, microscissors cutter hub inferior lobe 4 and hand-held caliper inferior lobe 7 junctions, both junctions connect by screw 5, micro-leaf 1 on the needle body and micro-two the relative faces of needle body inferior lobe 2 of holding held are for holding dial, hold dial and adopt not threaded plane, smoothed curve is adopted in the micro-junction, top of leaf 3 of holding on the needle body on the leaf 1 and microscissors cutter hub, all there is the employing smoothed curve micro-junction, below of holding needle body inferior lobe 2 and microscissors cutter hub inferior lobe 4, micro-ly hold on the needle body that the smoothed curve and the micro-smoothed curve structure of holding the junction, below of needle body inferior lobe 2 and microscissors cutter hub inferior lobe 4 of the junction, top of leaf 3 match on the leaf 1 and microscissors cutter hub, leaf 6 ends are fixed by leaf 8 one ends on rivet 10 and the detachable spring leaf on the hand-held caliper, hand-held caliper inferior lobe 7 ends are fixed by rivet 10 and detachable spring leaf inferior lobe 9 one ends, and leaf 8 other ends are connected by spring leaf bayonet socket 11 with detachable spring leaf inferior lobe 9 other ends on the detachable spring leaf.
In this utility model, the outer surface of leaf 6 and hand-held caliper inferior lobe 7 is provided with slip-proofing device on the described hand-held caliper.
This utility model can be used among the microsurgery of clinical positions such as ophthalmology, vascular surgery, neural microsurgery.When also can be used for needing the independent operation micro suture in the zoopery.
This device can be after the micro-needle holder that uses this one apparatus finishes micro suture, use the micro-shears of this one apparatus to carry out accurate toe-in pruning immediately, the hand mobile range is little simultaneously, thereby reaches the effect that does not need assistant and fast accurate micro suture.
The beneficial effects of the utility model are:
1, the micro-linking part of holding needle body and microscissors cutter hub is designed at grade, needn't make when guaranteeing that carry out toe-in prunes to hold pin portion and open excessively, and suture is easy to slip into the section between the microscissors cutter hub upper and lower lobes.
2, hold pin portion and microscissors cutter hub and be designed to crooked shape, the mobile range of patient's hand when reducing micrurgy.
