Abstract
The utility model relates to a novel lacrimal sac opener and belongs to the technical field of ophthalmological medical instruments. The novel lacrimal sac opener comprises an elastic frame, an arc-shaped metal sheet, opening claws, rectangular metal sheets and the like, wherein the rectangular metal sheets being 8mm high are symmetrically manufactured at two ends of an opening of the elastic frame; four opening claws vertical to the elastic frame are manufactured at the bottom of the elastic frame; one end of the arc-shaped metal sheet is mounted on one side of the middle part of the elastic frame through a moveable locking pin; and a positioning locking bolt is arranged in an arc-shaped locking chute of the arc-shaped metal sheet. According to the novel lacrimal sac opener, the rectangular metal sheets being 8mm high are manufactured at two ends of the opening of the elastic frame and the four opening claws vertical to the elastic frame are manufactured at the bottom of the elastic frame, so that the scope for stressing muscular tissues is wide during a use process, the effect of hemostasis by compression is good, the exposed operation visual field is wide, the deep muscular tissues can be exposed, and the blood is prevented from flowing into the operation visual field from the opening claws during an operation process. Besides, the arc-shaped metal sheet is mounted in the middle of the elastic frame, the bouncing range can be randomly regulated and controlled and the eyeball is prevented from being hurt by excessive bouncing.
Description
Technical field
This utility model relates to a kind of novel lachrymal sac dilator, belongs to the ophthalmic medical instrument technical field.
Background technology
Ophthalmology needs to use the lachrymal sac distraction instrument in doing dacryocystorhinostomy or row lachrymal sac excising operation, so that accomplish operation smoothly.At present, the lachrymal sac dilator structure of ophthalmology use is to adopt two drawing arms splitting clinically; The rear end of two drawing arms is connected on the operation screw rod, and the front end of two drawing arms is manufactured with and retracts the palm, and retracting palm has 3 to strut pawl; Strut pawl and be column, L-shaped, it highly is 3mm.Can not expose deep muscle tissue in this lachrymal sac dilator use, the hemostasis by compression weak effect causes intraoperative hemorrhage often to flow in the surgical field of view between the pawl from strutting; In addition, because it is less to strut the pawl number, have only 3, the muscular tissue that causes strutting is few, and the surgical field of view of exposure is little, the influence operation fast, carry out smoothly.
Summary of the invention
The purpose of this utility model is: a kind of novel lachrymal sac dilator is provided, and it struts operative incision automatically through elastic shelf, and through positioning and locking screw positioning and locking; Can be fine exposure deep muscle tissue, hemostasis by compression is effective, the muscular tissue that struts is many, the surgical field of view of exposure is big, be beneficial to operation fast, carry out smoothly.
This utility model is realized above-mentioned purpose through following technical scheme:
This novel lachrymal sac dilator by elastic shelf, movable safetied pin, positioning and locking screw, arc locking chute, arc metal plate, strut pawl and rectangular metal sheet constitutes; It is characterized in that: elastic shelf is the U type structure that is bent into by steel wire, and the opening two ends symmetry of elastic shelf is manufactured with and is that highly the rectangular metal sheet of 8mm, the bottom of each rectangular metal sheet are manufactured with 4 perpendicular pawls that strut; One end of arc metal plate is contained in the one side at elastic shelf middle part through movable safetied pin, and the middle part of arc metal plate has arc locking chute, is provided with the positioning and locking screw in the arc locking chute.
This utility model beneficial effect compared with prior art is:
Symmetry is manufactured with and highly is the rectangular metal sheet of 8mm this novel lachrymal sac dilator at the opening two ends of elastic shelf; And be manufactured with 4 perpendicular pawls that strut in the bottom of rectangular metal sheet, and it is big to make that this novel lachrymal sac dilator is in use oppressed the muscular tissue scope, and hemostasis by compression is effective; The muscular tissue that struts is many; The surgical field of view that exposes is big, can expose deep muscle tissue, can prevent in the art hemorrhagely to flow in the surgical field of view from strutting between the pawl.In addition, arc metal plate is housed, can arbitrarily regulates and control to flick amplitude, avoid flicking excessive damage eyeball at the elastic shelf middle part.This novel lachrymal sac dilator is reasonable in design, draws materials easily, and is easy to use, cheap, is easy to promote.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of novel lachrymal sac dilator.
Among Fig. 1: 1, elastic shelf, 2, movable safetied pin, 3, the positioning and locking screw, 4, arc locking chute, 5, arc metal plate, 6, strut pawl, 7, rectangular metal sheet.
The specific embodiment
This novel lachrymal sac dilator by elastic shelf 1, movable safetied pin 2, positioning and locking screw 3, arc locking chute 4, arc metal plate 5, strut pawl 6 and rectangular metal sheet 7 constitutes.Elastic shelf 1 is to bend the U type structure that forms by a steel wire; Elastic shelf 1 can open through elasticity automatically; The opening two ends symmetry of elastic shelf 1 is manufactured with and highly is the rectangular metal sheet 7 of 8mm; The bottom of each rectangular metal sheet 7 is manufactured with 4 and struts pawl 6, struts pawl 6 and rectangular metal sheet 7 vertical installations.The middle part that one end of arc metal plate 5 is contained in elastic shelf 1 through movable safetied pin 2 on one side, the middle part of arc metal plate 5 has arc locking chute 4; One end of arc metal plate 5 is locked on the elastic shelf 1, can rotate along movable safetied pin 2, is provided with positioning and locking screw 3 (referring to accompanying drawing 1) in the arc locking chute 4 of arc metal plate 5.
When using this novel lachrymal sac dilator to do dacryocystorhinostomy or row dacryocystectomy, after local infiltration anesthesia and nerve block anesthesia, separate skin, subcutaneous tissue and muscular tissue; Strut muscular tissue with strutting the elasticity of pawl 6 then, and oppress rectangular metal sheet 7 on muscular tissue, muscular tissue is strutted to suitable amplitude through elastic shelf 1; Separate again 3 lockings of positioning and locking screw, and then to deep muscle tissue, along with the intensification of operative site; To strut pawl 6 and rectangular metal sheet 7 moves to the deep; Expose lachrymal sac at last, behind the exposure lachrymal sac, the subsequent operation of operation can be undertaken by routine.
