Description
Technical field
This utility model relates to a kind of cataract cutting cystoma device, belongs to technical field of medical instruments.
Background technology
Cataract operation is the operation saving vision, briefly: method is to be made otch by limbus of corneae, enters the eye-chamber, anterior lens capsule is torn a bag mouth, remove muddy nucleus lentis and cortex, then transparent artificial intraocular lenses be placed in rear pouch.
Crystalline lens is made up of crystalline peplos and lens fibers, is attached to ciliary processes by means of apparatus suspensorius lentis, and lens fibers increases gradual aging with the age, becomes muddiness and forms cataract.Capsulorhexis is a very important link in whole cataract procedure, and technology requires height, and maneuver dynamics difficulty is grasped, and especially for junior doctor, is difficult to especially grasp capsulorhexis skill.So designing a kind of performance safety, simple operation, the cataract capsulorhexis medical apparatus and instruments that tact skill is easily grasped is extremely urgent.
Summary of the invention
The purpose of this utility model is in that to overcome in prior art cyst membrane and is easily shredded, and front pouch mouth tears irregular, operates length consuming time, junior doctor maneuver is difficult to the defects such as control, it is provided that a kind of performance safety, simple operation, consuming time short, junior doctor capsulorhexis technology is required relatively low a kind of cataract cutting cystoma device.
This utility model is to solve by the following technical programs: include injection tube, piston rod, piston rod is in injection tube and makes clearance fit, wherein injection tube front portion is provided with and suddenly extends neck tube section and coordinate with the centring ring with cutter groove, being provided with the barrier plate of a center band circular hole in injection cylinder, afterbody is provided with the fixing block that a center is four square holes；Piston rod back segment is the cubic cylinder with plug holder, the fixing block of its traverse injection tube afterbody, piston rod stage casing is thin cylinder, the barrier plate of the center band circular hole in its traverse injection tube, the stage casing being wherein between barrier plate and cylinder front end, four directions is cased with spring, piston rod leading portion is the one end steel wire with microknife, and it suddenly extends neck tube section, microknife and centring ring card slot fit through injection tube front portion.
Further, above-mentioned centring ring head is provided with female thread hard tube, suddenly extends the external screw thread that neck tube section is provided with injection tube front portion and matches linking.
This utility model enters in the eye-chamber by the centring ring that injection tube is anterior, centring ring is placed in anterior lens capsule surface and adjusts orientation, then front push piston bar, steel wire front end microknife is made to enter in centring ring draw-in groove, by microknife along draw-in groove circular trace, anterior lens capsule is marked a circular bag mouth；Whole operating process is quick, the smooth rule of bag mouth, and operating technology is prone to grasp.
Accompanying drawing explanation
Fig. 1 is this utility model embodiment overall structure schematic diagram.
Fig. 2 is this utility model embodiment locating ring structure schematic diagram.
Detailed description of the invention
Below in conjunction with embodiment accompanying drawing, the utility model is described in further detail.
As shown in the figure, including injection tube 1, piston rod is constituted by leading portion 11, stage casing 8 and back segment 7, piston rod is in injection tube 1 makes clearance fit, wherein injection tube 1 front portion is provided with and suddenly extends neck tube section 3 and coordinate with the centring ring 4 with cutter groove, being provided with the barrier plate 5 of a center band circular hole in injection tube 1 body, afterbody is provided with the fixing block 6 that a center is four square holes；Piston rod back segment is the cubic cylinder 7 with plug holder 2, the fixing block 6 of its traverse injection tube 1 afterbody, piston rod stage casing is thin cylinder 8, the barrier plate 5 of the center band circular hole in its traverse injection tube 1, the stage casing being wherein between barrier plate 5 and cylinder 7 front end, four directions is cased with spring 9, piston rod leading portion is the one end steel wire 11 with miniature double-edged blade 10, and it suddenly extends neck tube section 3, miniature double-edged blade 10 and centring ring 4 card slot fit through injection tube 1 front portion.
Further, above-mentioned centring ring 4 head is provided with female thread hard tube 12, and the external screw thread being provided with neck tube section 3 matches linking.
In operating process, enter in the eye-chamber by the centring ring 4 of injection tube 1 front portion, centring ring 4 is placed in anterior lens capsule surface and adjusts orientation, then with push piston bar before hands, the miniature double-edged blade 10 in steel wire 11 front end is made to enter in centring ring 4 draw-in groove, by miniature double-edged blade 10 along draw-in groove circular trace, anterior lens capsule is marked a circular bag mouth；Whole operating process is quick, the smooth rule of bag mouth, and operating technology is prone to grasp.
In use, according to patient profiles, centring ring 4 can be furnished with the model that varies in size.
