Description

Head fixer for ophthalmic operation

Technical Field

The utility model relates to the field of medical instruments, in particular to a head fixator for an ophthalmologic operation.

Background

When performing ophthalmic surgery, the head of a patient needs to be fixed to avoid swinging.

Most of the existing fixators adopt a structure that two fixing plates directly clamp and fix the head. For example, patent document CN212037777U discloses a head fixing device for a supine position operation of pediatric surgery in an anesthesia department, which comprises two sets of oppositely arranged bed plate fixing frames and two sets of oppositely arranged head fixing mechanisms; the bed board mount includes: the first fixing plate and the second fixing plate are arranged oppositely, the vertical plate is vertically arranged between the first fixing plate and the second fixing plate, the second fixing plate is provided with a first screw hole, and the adjusting bolt is in threaded connection with the screw hole; the head fixing mechanism comprises a stand column, an adjusting rod and a head positioning baffle, the stand column is vertically arranged on a first fixing plate, one end of the adjusting rod is fixed on the head positioning baffle, the other end of the adjusting rod is rotatably arranged on the stand column, and the head positioning baffle can be conveniently fixed to the head of a child.

Patent document CN107898586A discloses a head fixing device for ophthalmologic operation, which also relies on two fixing plates to directly clamp and fix the head, and only the driving manner of the fixing plates is different from that of the previous patent.

The head is directly clamped and fixed by the two fixing plates, and the shapes of the fixing plates cannot be matched with the shapes of the heads of patients due to different head shapes of different people, so that the contact area between the fixing plates and the heads of the patients is not large. If a larger clamping force is adopted, the pressure born by the head part of the patient is large, and the patient is uncomfortable. If a smaller clamping force is used, the fixing effect is poorer. In addition, the fixing plate can only prevent the head of the patient from swinging left and right, and the head fixer does not have the design of preventing the head of the patient from rising and can not prevent the head of the patient from rising.

labeled as: the pillow comprises a fixed seat 1, a bottom plate 11, a guide groove 111, a side plate 12, a deformable pillow 2, a flexible headrest 21, a pillowcase 22, particles 23, a lifting lug 24, a pressing plate 3, a dovetail-shaped sliding block 31, a push rod 4 and a head band 5.

Detailed Description

The utility model is further described with reference to the following figures and detailed description.

Head fixer for ophthalmic surgery is including warping pillow 2 and fixed knot structure, warp pillow 2 and place on fixed knot structure, warp pillow 2 and include flexible headrest 21 and pillowcase 22, and pillowcase 22 encircles flexible headrest 21 and sets up, and pillowcase 22 intussuseption is filled with particulate matter 23, and fixed knot structure can warp pillow 2 to warping 2 central direction extrusion.

As shown in FIG. 3, in the case of ophthalmic surgery, the patient lies down with his head on the flexible head pad 21; then the edge of the pillowcase 22 is lifted, and the periphery of the deformable pillow 2 is lifted and attached to the head; then the fixing structure is used for extruding the deformable pillow to complete the head fixing. Therefore, the particles 23 are filled between the fixing structure and the head of the patient, so that the fixing effect is better; in addition, the contact area between the deformable pillow and the head of a human body is large, and the comfort is better; the extrusion force can be properly increased, the fixing effect is improved, and discomfort of a patient can not be caused. Therefore, the utility model has the beneficial effect of good fixing effect. The height of the deformable pillow 2 is preferably substantially the same as the height of the patient's face when the head restraint is used in ophthalmic surgery.

The flexible head cushion 21 serves to support the head of the patient and may be made of a conventional flexible material, such as silicone. The pillow case 22 and the particles 23 play a role in fixing the left and right sides of the head of the patient to prevent the head of the patient from swinging left and right, and also play a role in preventing the head of the patient from rising. The particulate matter 23 is preferably fine sand. The pillow cover 22 should be able to avoid fine sand escaping. In order to facilitate lifting of the pillow case 22, the deformable pillow 2 comprises a lifting lug 24, and the lifting lug 24 is connected with the pillow case 22.

The specific structure of the fixing structure is preferably as follows: the fixing structure comprises a fixing seat 1, a pressing plate 3 and an ejector rod 4; the fixed seat 1 comprises a bottom plate 11 and two side plates 12 connected to two ends of the bottom plate 11, wherein the bottom plate 11 is provided with a guide groove 111; the deformable pillow 2 is placed on the fixed seat 1; the number of the compression plates 3 is two, the two compression plates 3 are respectively positioned at two sides of the deformable pillow 2, the bottom end of each compression plate 3 is matched with the guide groove 111, the compression plates 3 can move along the guide grooves 111 to be close to or far away from the deformable pillow 2, and one side, facing the pillowcase 22, of each compression plate 3 is arc-shaped; ejector pin 4 and curb plate 12 threaded connection, ejector pin 4 can push up pressure strip 3 tightly.

The compression plate 3 is moved inwards and is tightly pushed by the ejector rod 4, and the compression plate 3 can compress the deformable pillow 2. Otherwise, the compression plate 3 is moved outwards, the deformation pillow 2 collapses due to the fluidity of the particles 23, and the fixation of the head of the patient is released. The shape of the side of the pressing plate 3 facing the pillowcase 22 is arc, so that the shape of the side of the pressing plate 3 facing the pillowcase 22 is basically matched with the shape of the head of a patient, the fixing effect is improved, and the particles 23 are prevented from flowing outwards.

In order to prevent the patient from rising head more effectively, the fixing structure preferably comprises a head band 5, and the head band 5 can be connected with the two compression plates 3. After the head of the patient is fixed by the deformable pillow 2, the head band 5 is connected, and the forehead of the patient is pressed by the head band 5, so that the head of the patient can be prevented from rising.

Specifically, the guide groove 111 is preferably a dovetail groove, and the bottom of the pressing plate 3 is provided with a dovetail-shaped slider 31, and the dovetail-shaped slider 31 is matched with the guide groove 111. The dovetail groove is a common guide groove, and the dovetail-shaped sliding block 31 is matched with the dovetail groove, so that the pressing plate 3 can be prevented from moving upwards besides realizing moving and guiding of the pressing plate 3.
