The specific embodiment
For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing and describe the specific embodiment of the present utility model in detail.
Fig. 1 shows bulbar conjunctiva polyp in embodiment of this utility model and peels off and strike off double purpose device, and this bulbar conjunctiva polyp is peeled off and struck off double purpose device and can be used for peeling off bulbar conjunctiva polyp and strike off bulbar conjunctiva polyp dual-purpose.Bulbar conjunctiva polyp is peeled off and is struck off double purpose device and comprise interconnective handpiece 10, peel off and strike off part 20 and peel off and strike off part 30.
Handpiece 10 is strip, for hand-held to carry out operation technique for user.Preferably, handpiece 10 cross sections are circular, and handpiece 10 is cylinder, also can be provided for the decorative pattern of increasing friction force on it.
Peel off and strike off part 20 and peel off and strike off part 30 for peeling off and strike off bulbar conjunctiva polyp.Peel off and strike off part 20 and strike off part 30 and be connected with handpiece 10 respectively with peeling off, and peel off to strike off part 20 and peel off and strike off part 30 and be connected to handpiece 10 two ends.Wherein, peel off and strike off part 20 and peel off the radian adaptive left eye eyeball of difference and the right eye eyeball that strikes off part 30.Understandably, peel off to strike off part 20 and peel off the position of striking off part 30 and also can exchange.Further, peel off and strike off part 20 and/or peel off that to strike off part 30 be 120 °-150 ° with the angle of handpiece 10.Preferably, peel off and strike off part 20 and/or peel off that to strike off part 30 be 135 ° with the angle of handpiece 10.
As shown in Figure 2 and Figure 4, peel off and strike off part 20 and comprise that main body 21, blunt separation head 22, blunt separation portion 23 and sharp property strike off portion 24.Wherein, main body 21 is elongated, and blunt separation head 22, blunt separation portion 23 and sharp property are struck off portion 24 and be all positioned at main body 21 edges.Main body 21 is connected in handpiece 10 first ends and is crossed out to the first side by this end, and crooked towards the direction away from handpiece 10 second ends.
Main body 21 is flat, and it is crooked and form a radian matching with eyeball towards the outside.Understandably, because the radius of curvature of people's eyeball is generally 8.2-8.9mm, therefore the radius of curvature of this radian is preferably designed for to 8.0-9.0mm, so that peel off, strikes off part 20 and match with eyeball.Main body 21 one end are connected with handpiece 10, and the other end is provided with blunt separation head 22.
Blunt separation portion 23 and sharp property are struck off in two opposite edges that portion 24 lays respectively at main body 21, and blunt separation portion 23 and sharp property are struck off portion 24 and extended along its length in main body 21.Blunt separation portion 23 is the blunt passivity knife-edge of edge circle, and sharp property is struck off portion 24 for the sharp property sword limit of clear-cut margin.
Blunt separation head 22 is positioned at main body 21 ends and is connected with blunt separation portion 23.Preferably, blunt separation head 22 is circular arc, and blunt separation portion 23 strikes off portion 24 with sharp property and is connected with circular arc two ends on blunt separation head 22 respectively.Preferably, main body 21, blunt separation head 22, blunt separation portion 23 and sharp property are struck off portion 24 and are wholely set.
As shown in Figure 3, understandably, peel off and strike off part 30 structure and be with peeling off the main distinction of striking off part 20, peel off and strike off position that blunt separation portion 33 and sharp property in part 30 strike off portion 34 and strike off blunt separation portion 23 and sharp property in part 20 and strike off the position opposite of portion 24 with peeling off.Peel off to strike off part 20 and peel off and strike off part 30 and be respectively used to peel off heterochiral different eyeball.Peel off the main body 31 of striking off part 30 and be connected in handpiece 10 second ends and crossed out to the second side by this end, and crooked towards the direction away from handpiece 10 first ends, and the second side is relative with the first side.
Main body 31 is flat, and it is crooked and form a radian matching with eyeball towards the outside.Understandably, because the radius of curvature of the eyeball of human body is generally 8.2-8.9mm, therefore the radius of curvature of this radian is preferably designed for to 8.0-9.0mm, so that peel off, strikes off part 30 and match with eyeball.Main body 31 one end are connected with handpiece 10, and the other end is provided with blunt separation head 32.
Blunt separation portion 33 and sharp property are struck off in two opposite edges that portion 34 lays respectively at main body 31, and blunt separation portion 33 and sharp property are struck off portion 34 and extended along its length in main body 31.Blunt separation portion 33 is the blunt passivity knife-edge of edge circle, and sharp property is struck off portion 34 for the sharp property sword limit of clear-cut margin.
Blunt separation head 32 is positioned at main body 31 ends and is connected with blunt separation portion 33.Preferably, blunt separation head 32 is circular arc, and blunt separation portion 33 strikes off portion 34 with sharp property and is connected with circular arc two ends on blunt separation head 32 respectively.Preferably, main body 31, blunt separation head 32, blunt separation portion 33 and sharp property are struck off portion 34 and are wholely set.
In conjunction with shown in Fig. 1 to Fig. 3, for example, when an eyeball is carried out to bulbar conjunctiva polyp scraping operation, use peeling off of adaptive this eyeball shape strike off part 20 or peel off and strike off after part 30 peels off, owing to peeling off, strike off in part 20 blunt separation portion 23 and sharp property and strike off portion 24 and strike off blunt separation portion 33 and sharp property in part 30 and strike off the position opposite of portion 34 with peeling off, therefore need to strike off part 20 by peeling off or peel off to strike off part 30 and switch in striking off step, switching to another peels off and strikes off part 30 or peel off and strike off part 20, like this, another is peeled off and strikes off part 30 or peel off the sharp property of striking off part 20 and strike off portion 34 or sharp property and strike off portion 24 and just conform to this eyeball shape, so can strike off.
Operating procedure while carrying out treatment of pterygium operation below in conjunction with Fig. 1 to Fig. 4 to using bulbar conjunctiva polyp in this utility model embodiment to peel off to strike off double purpose device describes:
A operator wears mask after sterilization, medicated cap etc., is ready to the disposable sterilized bulbar conjunctiva polyp aseptic bag of performing the operation, and the bulbar conjunctiva polyp in this utility model embodiment is peeled off and struck off double purpose device and be positioned at the disposable sterilized bulbar conjunctiva polyp aseptic bag of performing the operation;
B strict sterilization field of operation;
C opens the disposable sterilized bulbar conjunctiva polyp aseptic bag of performing the operation, and takes out bulbar conjunctiva polyp and peels off and strike off double purpose device;
D peels off the blunt separation head 22/ blunt separation head 32 and the blunt separation portion 23/ separated conjunctiva of blunt separation portion 33 and bulbar conjunctiva polyp that strikes off double purpose device with bulbar conjunctiva polyp, peel off bulbar conjunctiva polyp and cornea, sclera;
E strikes off the sharp property of portion 34/ by sharp property and strikes off portion's 24 corneal surfaces bulbar conjunctiva polyps and strike off, and makes cornea face recover smooth.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under this utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in several improvements and modifications that do not depart under this utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
