Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, an embodiment of the present invention is shown: the utility model provides a patient's head anti-moving device for ophthalmic surgery, including fixed support body 1, the inside wall of fixed support body 1 is fixed with head supporting pad board 2, the top of fixed support body 1 is provided with lamina tecti 3, the internally mounted of lamina tecti 3 has head fixed subassembly 4, head fixed subassembly 4 is including built-in cavity 41, and built-in cavity 41 sets up the inside at lamina tecti 3, sliding tray 42 has been seted up to lamina tecti 3's bottom, gear 44 is installed through the bearing in the inside intermediate position department of built-in cavity 41, and gear 44's both sides mesh respectively has rack 45, rack 45 is close to the bottom fixedly connected with head of gear 44 one end and adds holding piece 46, and head adds holding piece 46 and runs through sliding tray 42 and extends to head supporting pad board 2 top position department, and sliding connection between head holding piece 46 and the sliding tray 42.

Further, bar-shaped rubber convex blocks are transversely arranged on the surfaces of the head supporting base plate 2 and the head clamping piece 46, the bar-shaped rubber convex blocks are uniformly distributed on the surfaces of the head supporting base plate 2 and the head clamping piece 46 at equal intervals, as shown in the attached

drawings

1 and 4, the rubber convex blocks on the surfaces of the head supporting base plate 2 and the head clamping piece 46 are designed, the main material is natural latex raw material foam to form the rubber convex blocks, the elastic force is excellent, the elastic resilience is good, the deformation-free rubber characteristic is realized, so that the contact surfaces between the head supporting base plate 2 and the head clamping piece 46 and the head of a patient have certain elastic resilience, the buffering effect is realized, and the condition that the surface of the head of the patient is damaged due to the overlarge extrusion force of the head clamping piece 46.

Further, the preformed hole has all been seted up at the top of lamina tecti 3, and the inside threaded connection of preformed hole has locking bolt 43, and locking bolt 43 has lock washer with the junction pressfitting of preformed hole, it is shown according to fig. 4 and fig. 5, through the locking bolt 43 in the rotatory preformed hole, can realize the operation that two sets of racks 45 are fixed, and because lock washer's design, the connection stability between locking bolt 43 and the preformed hole has been strengthened, the gasket can play the buffering and prevent the not hard up effect of locking bolt 43 nature.

Furthermore, the length of the sliding groove 42 is the same as the length of the rack 45, and a gasket is pressed at the joint of the sliding groove 42 and the top of the head clamping piece 46, as shown in fig. 1, fig. 3, fig. 4 and fig. 5, one group of head clamping pieces 46 is held by hand to drive the rack 45 to transversely move along the sliding groove 42 to approach the head, due to the design of mutual engagement between the rack 45 and the gear 44, the gear 44 engaged with the rack 45 can rotate along with the transverse movement of the rack 45, and the other group of rack 45 is driven to drive the other group of head clamping pieces 46 to transversely move along the sliding groove 42 in the opposite direction, so that the two groups of head clamping pieces 46 synchronously approach the head of the patient, the tightness of the two groups of head clamping pieces 46 can be adjusted according to the head size of the patient, the stability of the head of the patient is increased, and as the length of the sliding groove 42 is the same as the length of, make rack 45 drive the head and add the length that the piece 46 moved along sliding tray 42 unanimous, and through the design of gasket, can reduce the fit clearance between sliding tray 42 and the head adds the piece 46, avoid removing the in-process because the emergence is rocked and lead to the condition that sliding tray 42 and head add the piece 46 not to lean on, strengthen the head and add the stability when piece 46 removed.

Further, the head adds and holds piece 46 and be provided with two sets ofly, and two sets of heads add the inner wall that holds piece 46 and set up to half-circular arc, and it is shown according to fig. 4 because the head adds and holds piece 46 and be curved setting, laminates more with the head of disease, is favorable to playing good protective effect, also strengthens the comfort level when patient's head is fixed simultaneously.

The working principle is as follows: when the patient is ready to check the eyes, the head is extended into the fixing frame body 1 and the chin is lapped at the middle position of the head supporting cushion plate 2, according to the size of the head of the patient, the two groups of locking bolts 43 are respectively rotated and unscrewed from the reserved holes, one group of head clamping pieces 46 are held by hands to drive the rack 45 to transversely move along the sliding groove 42 to approach the head, due to the design of the mutual engagement between the rack 45 and the gear 44, the gear 44 engaged with the rack 45 can be rotated along with the lateral movement of the rack 45, and drives another set of rack 45 to drive another set of head clamping piece 46 to perform reverse transverse movement along the sliding slot 42, so that the two groups of head clamping sheets 46 synchronously approach to the head of the patient to be clamped, the locking bolts 43 in the reserved holes are sequentially rotated and screwed inwards, can fix the head of the patient well so as to facilitate the examination operation of medical personnel, and the above is the whole working principle of the utility model.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
