Detailed Description

The invention will be further described with reference to examples of embodiments shown in the drawings.

The suction type face opener shown in fig. 1 mainly comprises a support assembly 1, an eyelid opening assembly 2, a suction tube set 3 and the like.

The support assembly 1 includes two swing arms 11 disposed oppositely, two connecting members 12 with ends embedded into ends of the corresponding swing arms 11 (i.e., one connecting member 12 is fixed by inserting the end of the corresponding swing arm 11 into the connecting member), and an adjusting structure 13 connecting the two swing arms 11 for adjusting the opening degree of the connecting member. The two swing arms 11 can be directly pivoted at the ends, or can be arranged in the manner of the present embodiment (realized by the adjusting structure 12). Specifically, the adjusting structure 13 includes a supporting member 131 having two end portions pivotally connected to the other ends of the two swing arms 11 respectively (the supporting member 131 may be a straight plate-shaped or block-shaped structure having two end portions, each end portion is pivotally connected to the other end of one swing arm 11; both ends of the supporting member 131 are provided with an avoiding groove matching with the swing arms 11 to facilitate the action of the swing arms 11), a supporting sleeve 133 disposed between the two swing arms 11, two connecting rods 132 having one end pivotally connected to the middle portion of the corresponding swing arm 11 and the other end pivotally connected to the supporting sleeve 133 (the two connecting rods 132 may be connected to the supporting sleeve 133 by the same pivotal connecting shaft or by two different connecting shafts; the pivotal connecting portion is located at one end of the supporting sleeve 133), and an adjusting screw 134 penetrating through the supporting member 131 and having an end portion clamped in the supporting sleeve 133 (a convex ring body for clamping the end portion of the adjusting screw 134 is formed on the inner side wall, so that the adjusting screw 134 can rotate relative to the supporting sleeve 133), and the adjusting screw 134 is connected with the supporting member 131 through threads (i.e., the supporting member 131 is provided with a threaded hole matched with the adjusting screw 134). Thus, the adjusting screw 134 is rotated to drive the connecting rod 132 to move, and finally the opening degree between the two swing arms 11 is adjusted. In the present embodiment, the connecting member 12 includes a first connecting portion 121 fixed (usually by laser welding) inside the supporting rod 21 and parallel thereto, and a second connecting portion 122 connected to an end of the first connecting portion 121 and forming an obtuse angle therewith; the obtuse angle is preferably ≧ 140 and < 180, which if too small may result in a safety hazard by the suction face opener easily striking the patient's face during use. The connecting rod 132 is formed by two support plates in different planes and connected in a smooth transition mode, and the two connecting rods 132 are matched with each other instead of being symmetrical when in use.

The eyelid expanding components 2 are provided in two groups, which are respectively installed at the free ends of the two connecting pieces 12 and correspond to the two connecting pieces one by one, and are used for expanding the upper eyelid and the lower eyelid of the patient. Each set of eyelid retractor 2 includes a support rod 21 fixed to the corresponding connector 12 (i.e., the support rods 21 and the connectors 12 are in one-to-one correspondence, where the fixing is achieved by laser welding), an eyelid hook 22 formed at an end of the support rod 21 and having a plurality of suction holes 221 formed in an inner side thereof (in the present embodiment, each set of eyelid retractor 2 has two suction holes 221 symmetrically formed therein), a connection protrusion 23 formed at the other end of the support rod 21 (the support rod 21, the eyelid hook 22 and the connection protrusion 23 are generally integrally formed, and the eyelid hook 22 and the support rod 21 are formed by bending a titanium alloy wire), and a flow channel (as shown in fig. 2) formed in the support rod 21, the eyelid hook 22 and the connection protrusion 23 and communicated with the suction holes 221. Thus, the liquid such as tears and blood generated in the eye can be discharged through the suction hole 221 and the flow channel. The eyelid hook 22 and the aforementioned second coupling portion 122 are generally located on the same side of the support bar 21, so that the coupling protrusion 23 and the suction tube group 3, etc. are prevented from adversely affecting the patient during treatment.

The suction tube set 3 includes a main tube 31, two branch tubes 33 connected to the end of the main tube 31, and a suction needle 32 inserted into the other end of the main tube 31, wherein the free end of each branch tube 33 is fitted over the connecting protrusion 23 and extends to a part of the support rod 21 (i.e., the connecting protrusion 23 is inserted into the branch tube 33 so that the branch tube 33 covers a part of the support rod 21), so that a syringe can be mounted on the suction needle 32 to suck out the aforementioned tears, blood, and other liquids. In the present embodiment, two branch pipes 33 are connected to the main pipe 31 through a tee 34.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
