Specific embodiment

It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection It encloses.In addition, all connection/connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality Situation is applied, by adding or reducing couple auxiliary, Lai Zucheng more preferably coupling structure.Each technology in the utility model is special Sign, can be with combination of interactions under the premise of not conflicting conflict.

Referring to figs. 1 to Fig. 4, this is the embodiments of the present invention, specifically:

A kind of attraction crochet hook, including be in vertically arranged needle body 1, the needle body 1 is tubular structure, the needle body 1 Upper end is connected with coupler body 2, and being equipped with inside the needle body 1 is in the first vertically arranged attraction channel 11, the needle body 1 it is upper End face is equipped with suction port 12, and the upper end of first attraction channel 11 is connected to suction port 12, and the lower end of the needle body 1 connects Being connected to is in vertically arranged handle body 3, and being equipped with inside the handle body 3 is in the second vertically arranged attraction channel 31, described The upper end of the second attraction channel 31 be connected to the lower end of the first attraction channel 11, between the coupler body 2 and the axis of needle body 1 Equipped with angle, the angle of the angle is greater than 0 °.The second attraction channel in vacuum extractor and handle body 3 at the time of surgery, 31 connections, the tissue for attracting bleeding by the suction port 12 of the upper surface of needle body 1 and separating, doctor can in surgical procedure side It removes ear canal tissue side to attract, remains that visual area is clear, while being a certain included angle and setting between coupler body 2 and the axis of needle body 1 It sets, meets different patients because of the demand in the different aperture of ear canal, increase surgical procedure range, make that the operation is more convenient.

It is further used as preferred embodiment, the outer diameter of the needle body 1 is gradually increased from upper end to lower end.So that needle The lateral wall of body 1 is in certain taper, and the upper end convenient for needle body 1 puts in ear canal, improves the range of visual area, needle body 1 is put in Ear canal internal, when coupler body 2 being enabled to operate the tissue of ear canal, doctor can observe the feelings that coupler body 2 is contacted with tissue easily Condition, to improve the efficiency and success rate of operation.

It is further used as preferred embodiment, the angle between the coupler body 2 and the axis of needle body 1 is 180 °.Make It obtains coupler body 2 and needle body 1 is linearly arranged, be mainly used for the operation to tissue longitudinal in ear canal.

It is further used as preferred embodiment, the angle between the extended line of 1 axis of the coupler body 2 and needle body is 45°.Make the contact of the end of coupler body 2 with horizontal organization in ear canal in this way, while being in 45 ° of inclination, before meeting operation It puts, further increases the field range of operation, the sight of doctor is along needle body 1 towards the inside of ear canal, main detection hook The contact situation of body 2 and horizontal organization in ear canal, with it is more existing be in the crochet hook of 90 ° of angles compared with, it is wider on the visual field.

It is further used as preferred embodiment, the coupler body 2 is toward right bank or toward left bank.More different need It asks, coupler body 2 can be 45 ° toward left bank or toward the angle between right bank and the axis of needle body 1, to improve the function of crochet hook Energy.

It is further used as preferred embodiment, the coupler body 2 is in needle-shaped or in flat-shaped.It is main in acicular coupler body 2 For small tissue, and the use scope of crochet hook is improved mainly for slightly a little bigger tissue in flat-shaped coupler body 2, is in needle The accuracy that coupler body 2 is contacted with ear canal tissue can be improved in the coupler body 2 of shape, thus the success rate of operation, and exist in flat-shaped coupler body 2 When removing, each strip operation is peelable to separate out more ear canal tissues, reduces the number of removing, reduces the contusion to ear canal, mentions The efficiency of height operation.

The better embodiment of the utility model is illustrated above, but the utility model be not limited to it is described Embodiment, those skilled in the art can also make various equivalent changes without departing from the spirit of the present invention Type or replacement, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
