Abstract
The utility model provides a sac scarifying needle for an eye operation, which comprises a needle base matched with a liquid suction pipe, a hollow needle whose one end is connected with the needle base in communication and a knife needle whose head is bended arranged on the front portion of the hollow needle. The utility model is matched with the liquid suction pipe and combines a scalpel and a liquid suction device into integration. Partial scarification can be conducted. The liquid can be directly sucked. The wound surface of an eyeball operation is reduced. The infection chance is decreased. The operation and the use are convenient.
Description
The utility model relates to a kind of medical apparatus, particularly be that a kind of ophthalmology is drawn the capsule operation needle.
Present domestic ophthalmologic operation such as the cataract operation done, at first be to choose with scalpel to cut the eyeball film, and then the liquid after will cutting with the imbibition hordeolum sucks out, gurry is picked out, so continuous transposing medical apparatus, operating not only bothers but also inconvenient, and has prolonged operating time, surgical wound surface is big, easy infection.
In view of above reason, the purpose of this utility model is that ophthalmic easy for operation is drawn the capsule operation needle for wound surface after a kind of operation is provided is little.
The needle stand that can cooperate with pipette is arranged in this utility model, the hollow needle that an end is connected and communicates with needle stand, there is elbow knife needle (referring to Fig. 1) front portion of hollow needle, and integrates scalpel and aspirating needle after pipette cooperates, and is both convenient and postoperative wound surface is little.
Elbow knife needle centrage on the above-mentioned hollow needle and hollow shank centreline space angle 90 °＜α＜180 ° (referring to Fig. 1), elbow knife needle length: 0＜L＜2mm.
Elbow knife needle centrage in the above-mentioned hollow needle and hollow shank centreline space angle α=105 °, elbow knife needle length L=1.5mm(is referring to Fig. 1), surgical effect is good.
This utility model and pipette are used and integrate scalpel and aspirator, can carry out the part and choose and cut, and directly imbibition significantly reduces the operation on eyeball wound surface, reduce infection chance, and be easy for operation.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is this utility model structural representation
With reference to figure 1, the 90 °＜α of angle of the centrage of the hollow shank 2 in the hollow needle 1 and elbow knife needle 3 centreline spaces on it＜180 ° (best α=105 °), the elbow knife needle length 0＜L＜best L=1.5mm of 2mm().One end of hollow shank 2 is connected on the needle stand 4 and with needle stand 4 and communicates.The pipette 5 that can pack into and cooperate with it in the needle stand 4.
Claims (3)
1, draw the capsule operation needle, it is characterized in that having in the described operation needle needle stand that can cooperate with pipette, the hollow needle that an end is connected and communicates with needle stand, there is the elbow knife needle front portion of hollow needle.
2, as claimed in claim 1 stroke of capsule operation needle is characterized in that elbow knife needle centrage and 90 °＜α of hollow shank centreline space angle＜180 ° of elbow knife needle length on the described hollow needle: 0＜L＜2mm.
3, as claimed in claim 2 stroke of capsule operation needle is characterized in that elbow knife needle centrage in the described hollow needle and hollow shank centreline space angle α=105 °, elbow knife needle length L=1.5mm.
