Detailed Description

The present invention will be further described with reference to the accompanying drawings 1-3.

Referring to fig. 1, the embodiment of the present invention provides an auxiliary tool for ophthalmology retrobulbar injection, which includes a head fixing band 1, a connecting band 2, a face fixing band 3 and a needle insertion positioning assembly 4, wherein the head fixing band 1 is fixed on the head of a patient and is located at the forehead of the patient; the connecting belt 2 is used for connecting the head fixing belt 1 and the face fixing belt 3 at the same time; the face fixing band 3 is fixed on the face of the patient and is positioned on the lower edge of the orbit of the patient, and scales are arranged on the face fixing band 3 along the length direction of the band, so that an operator can conveniently determine the position of the needle inserting position of the patient according to the scales; the needle inserting positioning component 4 is arranged on the face fixing band 3 and can slide along the scale direction of the face fixing band 3, and the needle inserting positioning component 4 is used for the injection needle to enter.

When in use, an operator firstly fixes the head fixing belt 1 at the forehead of the head of a patient; then fixing the face fixing belt 3 on the face of the patient, and enabling the face fixing belt 3 to pass through the infraorbital margin of the patient; then the position of the intersection of the outer 1/3 in the lower margin of the orbit of the patient is determined through the scale, and the needle inserting positioning assembly 4 is moved to the position; finally, after the patient watches the needle towards the inner upper part, the needle can be inserted through the needle inserting positioning component 4. By the needle inserting mode, the operation of manually finding a needle inserting point by an operator is reduced, and the needle inserting point can be judged through scales, so that the problem that the needle inserting position is determined in a manual empirical mode and is not accurately found in the prior art during the retrobulbar injection is solved.

Referring to fig. 1 and 2, in particular, in the embodiment of the present invention, the head fixing band 1 includes a flexible mounting band 11 and two head pasting bands 12, and the flexible mounting band 11 may be made of silica gel and may deform under pressure; the two head adhesive tapes 12 are respectively fixed at two ends of the flexible mounting tape 11, can be supported by thread gluing and can be mutually adhered.

When the head fixing belt 1 is fixed on the forehead of the head of a patient, the flexible mounting belt 11 is arranged on the forehead of the patient, and the flexible mounting belt 11 is fixed in a mode that the two head pasting belts 12 are bonded together.

Of course, in other embodiments, the head fixation band 1 may be made of an elastic headband.

One side of the flexible mounting belt 11 is provided with a clamping groove 111, the clamping groove 111 is a stepped groove or a dovetail groove and has a limiting effect, and the groove length direction of the clamping groove 111 extends along the belt length direction of the flexible mounting belt 11.

The connecting band 2 can be made of silica gel, and one end of the connecting band is matched and connected in the clamping groove 111 in a sliding manner so as to be clamped on the flexible mounting band 11; and obviously, when the flexible installation belt 11 is fixed on the head of the patient, the flexible installation belt 11 is pressed to deform so as to limit the connecting belt 2, so that the connecting belt 2 is prevented from freely sliding, namely, when needed, the connecting belt 2 can be moved by applying force to the connecting belt 2.

An opening is arranged on the connecting band 2 for the sight line of the eyes of the patient to penetrate through, and the operator can observe the eye condition of the patient conveniently. An elastic belt 21 is fixed on the connecting belt 2, and an adhesive layer 211 is arranged at the end part of the elastic belt 21; before the needle is inserted, an operator adheres the adhesive layer 211 to the upper eyelid of the patient, and indirectly drives the upper eyelid of the patient to be pulled upwards through the pull-back action of the elastic band 21, so that the operation of automatically closing the eyes of the patient in the treatment process is reduced, and meanwhile, the patient is given a signal that the eyeball does not rotate downwards, so that the smoothness and the safety of the needle insertion are indirectly ensured.

The face fixing band 3 comprises two scale rods 31 and two face adhesive bands 32; the scale rods 31 can be made of silica gel, the two scale rods 31 are fixedly connected with the belt 2 at intervals, and the scale rods 31 are provided with scales; the face paste belt 32 is fixed on the end parts of the two scale rods 31 at the same time, and the two face paste belts 32 are fixed on the two ends of the scale rods 31 respectively, so that the face fixing belt 3 is fixed by pasting the belt 32 on the face of the patient.

The needle inserting positioning assembly 4 comprises two positioning rings 41, a connecting pipe 42, a needle inserting tube 43 and a rotating rod 44; the two positioning rings 41 are respectively sleeved and slidably connected with the two scale rods 31; the connecting tube 42 is fixed to both positioning rings 41; the needle inlet tube 43 is arranged in the connecting tube 42, and the lower side surface of the needle inlet tube 43 is higher than the lower side surface of the face fixing band 3; one end of the rotating lever 44 is fixed to the outer wall of the needle insertion tube 43, and the other end is rotatably connected to the needle insertion tube 43, and the longitudinal direction of the rotating lever 44 extends along the longitudinal direction of the scale rod 31.

After the face fixing band 3 is fixed on the face of the patient and the needle feeding position is determined by the scale of the scale rod 31, the positioning ring 41 is moved, so that the needle feeding tube 43 is moved to the needle feeding point; then, the needle can be inserted vertically through the needle insertion tube 43, and after the needle is inserted by 1cm, the needle insertion tube 43 can rotate along with the rotation of the needle when the needle is inclined upward to the nose.

Referring to fig. 3, the lower side of the connection tube 42 is lower than the lower side of the face fixing band 3, so that after the face fixing band 3 is fixed on the face of the patient, the lower side of the connection tube 42 can abut against the face of the patient, and a pressing action on the needle insertion region is formed. An adhesive area 421 and a sterile area 422 are provided at the lower side of the connecting tube 42, the connecting tube 42 is fixed at the needle insertion point through the adhesive area 421, the needle insertion positioning assembly 4 is prevented from moving during needle insertion, and the sterile area 422 is located in the adhesive area 421 for sterilization and infection of the needle insertion point.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
