Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Example 1

As shown in fig. 1 to 3, the present embodiment provides an adjustable head position fixer for ophthalmic surgery, which includes a fixing device and a limiting ring 10, wherein the limiting ring 10 is a reducing hoop;

the fixing device comprises a clamping piece and an adjusting device, the adjusting device comprises a transverse telescopic rod 21, a vertical telescopic rod 22 and a connecting piece 23, one end of the vertical telescopic rod 22 is fixedly connected with the top of the clamping piece, and the other end of the vertical telescopic rod is fixedly connected with the connecting piece 23; one end of the transverse telescopic rod 21 is fixedly connected with the connecting piece 23, and the other end is fixedly connected with the limiting ring 10.

When the fixing device is used, the clamping piece of the fixing device is clamped at the edge of the operating table, so that the whole fixer is fixed, and the phenomenon that the head of a patient moves to influence the normal operation of the operation due to the shaking of the fixer is avoided; after the patient recumbents in suitable position on the operation table, through adjusting device, the telescopic link of horizontal and two vertical directions of control removes for spacing collar 10 encircles in the patient head outside, then adjusts the diameter of reducing staple bolt, makes spacing collar 10 press close to the patient head, carries on spacingly to the patient head, avoids the patient head to take place to remove at the operation in-process, shortens operation time, improves the operation security.

In this embodiment, the clamping member includes an Contraband-type band member 30 and a fastening nut 31 provided at the bottom of the band member 30. The Contraband type hoop member 30 is clamped at the edge of the operating bed, and the fastening nut 31 is screwed tightly, so that the whole fixer can be fixed on the operating bed by the clamping member; after the use, loosen fastening nut 31, can take off the clamping piece from the operation table, the design of clamping piece makes the device not only fix firm to dismantle and simple to operate.
