Description

A kind of ophthalmostat

Technical field

The utility model is related to the adjustment structures of ophthalmostat, especially pressure ring.

Background technology

In ophthalmologic operation, ophthalmostat is a kind of common auxiliary instrument, and main function is to lodge external force to fix eye Subsequent operation is convenient in the position of ball.

Such as Chinese invention patent：A kind of ophthalmostat for full femtosecond SMILE operations, publication number： CN104921869A, publication date 2015-09-23, disclosed ophthalmostat include handle, connecting rod and fixed ring, described Handle includes the handgrip part of coaxial system on it, and one end of the handle is tilted admittedly by a side of connecting rod and fixed ring It is fitted together, plane of a loop and the handle of the fixed ring are inclined to set, and the center line of the handle, connecting rod and fixed ring is at one In plane.

For another example Chinese invention patent：A kind of rotary ophthalmostat of semicircle, publication number：CN104720970A, publication date： 2015-06-24, it discloses ophthalmostat, including device body and ophthalmostat device head, with anti-skid chequer with the device, The ophthalmostat device head is connected to device body left end, and the ophthalmostat device head left end is equipped with outer semi-ring and inner ring, outside partly Ring and inner ring are connect by support arm with ophthalmostat device head, and the inner ring is welded on inside outer semi-ring；Fixator passes through in device Anti-skid chequer is set with it, to increase gripping feel when medical staff uses, on the basis of original semi-ring, welds an inner ring, This inner ring is rotatable, to increase the applicability of different types of ophthalmologic operation.

The fixator of above-mentioned patent disclosure has its specific use occasion, and use scope is smaller, while the pressure of pressure ring Be inconvenient to adjust.

Invention content

The technical problems to be solved in the utility model is：A kind of ophthalmostat is provided, pressure ring part can it is round with Be switched fast between semicircle, pressure ring can opposite brackets rotation, be conveniently adjusted angle, meanwhile, holder is capable of providing additional pushing Power, entire fixator adjustment is more convenient, holds more comfortable.

The technical solution of the utility model is as follows：

A kind of ophthalmostat, including handle, handle end are connected with U-bracket, and two edge tails of U-bracket are in circle Bowing, and be flexibly connected with semicircle first pressure ring and semicircle second pressure ring by shaft；

Two sides of the U-bracket include bellows segment, and bellows segment, that is, section is in ups and downs wavy such as sinusoidal Waveform；

There are semi-circular recesses on the end face of first pressure ring, the adjustment spiral shell coaxial with shaft is provided on peripheral surface Mother, the shape of semi-circular recesses is identical as the shape of the second pressure ring, and can just store the second pressure ring is advisable.

The handle includes holding section and screwed length adjustment bar of the end face with screw hole.

The holding section includes a pair of parallel plane, and plane-parallel both ends are connected by arc section, the surface of arc section It is intervally distributed with slot.

It is arranged jagged on the peripheral surface of first pressure ring, convex block is provided on the second pressure ring peripheral surface.

The shaft is placed in pivoted housing, and pivoted housing outer surface is threadedly coupled with adjusting nut.

The protrusion of silica gel material is along the circumferential direction equidistantly provided on the end face of first pressure ring and the second pressure ring.

The relatively existing fixed appliance of the utility model has the advantage that：

1. the second pressure ring can be rotated relative to the first pressure ring, and be received into the semi-circular recesses of the first pressure ring, half is formed Round pressure ring；Second pressure ring is also deployable, is compressed by adjusting nut, and complete round pressure ring is formed with the first pressure ring, to Adapt to different use environments；

Bellows segment on 2.U shape holders can be additionally provided relative to form of straight lines since the restoring force of its flexible deformation is big It gives pressure ring certain pressure, while being easy to restore to the original state；

3. the convex block of notch and the second pressure ring peripheral surface on the first pressure ring peripheral surface coordinates, facilitate the first pressure ring and second Folding rotation between pressure ring；

4. the combination of shaft and pivoted housing enables to pressure ring can opposite brackets rotation and the opposite locking of realization；

5. the parallel plane and slot on handle had not only facilitated gripping, but also can be anti-skidding；

6. the combination of holding section and length adjustment bar facilitates the use scope of extension fixator.

Specific implementation mode

As shown in Figure 1, a kind of ophthalmostat, including handle 1,1 end of handle are connected with U-bracket 2, U-bracket 2 Two edge tails are in arc-shaped bend, and are flexibly connected with semicircle first pressure ring 4 and semicircle second pressure ring 6 by shaft 5； Two sides of U-bracket 2 include respectively one section of bellows segment 3；There are semi-circular recesses 7 on the end face of first pressure ring 4, is set on peripheral surface It is equipped with the adjusting nut 8 coaxial with shaft 5.

As shown in Fig. 2, shaft 5 is placed in pivoted housing 81,81 outer surface of pivoted housing is threadedly coupled with adjusting nut 8.

As shown in figure 3, jagged 41 are arranged on the peripheral surface of the first pressure ring 4, it is provided on 6 peripheral surface of the second pressure ring The protrusion of silica gel material is along the circumferential direction equidistantly provided on the end face of convex block 61, the first pressure ring 4 and the second pressure ring 6.

As shown in figure 4, handle 1 includes the holding section and screwed length adjustment bar 9 that end face carries screw hole.Holding section 11 include a pair of parallel plane 111, and the both ends of parallel plane 111 are connected by arc section 112, the surface interval of arc section 112 Slot 113 is distributed with.

In use, length of rotation adjusts bar 9 as needed, it is made to elongate or shorten.According to actual conditions, selection is semicircle Pressure ring or round pressure ring unclamp adjusting nut 8 when needing the former, pinch convex block 61, rotate second the 6 to the first pressure ring of pressure ring 4 Groove 7 in, then lock adjusting nut 8.When needing using the latter, adjusting nut 8 is first unclamped, the second pressure ring 6, shape are rotated out of At adjusting nut 8 is locked after complete circle again.
