Description
Technical field
This utility model belongs to medical instruments field, is specifically related to the drag hook that mirror auxiliary little otch thyroid operation in a kind of Miccoli chamber is used.
Background technology
Thyroid operation is had relatively high expectations to beauty treatment, and present well accepted thyroid operation mode is the auxiliary little otch thyroid operation of Miccoli chamber mirror.The Miccoli operation does not have work chamber truly, the complete provisional lacuna that leans on drag hook to form of its observation and operation.The chamber means of building commonly used at present are to use goitre retractor to carry out tractive by manpower, but its existence is a lot of not enough: 1, less owing to skin incision, and the restricted width of drag hook, the space that tractive is formed is narrow and small; 2, grasp by its dynamics of manpower tractive is difficult, very high to assistant's requirement; 3, at operating time than long time, need long manpower tractive, hands lead instability makes operation easier increase and often image interrupt and influence the operation process.
Summary of the invention
The purpose of this utility model is, a kind of special-purpose drag hook of the auxiliary little otch thyroid operation of Miccoli chamber mirror that can carry out tractive intensity, tractive range regulation as required is provided.
In order to realize above-mentioned task, this utility model is taked following technical solution:
The special-purpose drag hook of the auxiliary little otch thyroid operation of a kind of chamber mirror is characterized in that, comprises the base that is connected with operation table; Base is connected with draw-in groove through screw mandrel, and base is connected with a L type support, on the L type support fixed block is arranged; T type bolt is installed on the fixed block, and there is connecting hole the lower end of T type bolt, below T type bolt, is connected with elevating lever; The corresponding fixing hole of lower end connecting hole with T type bolt is arranged on the elevating lever, also have plate to turn round on the elevating lever, a pair of drag hook is arranged at the elevating lever bottom; Drag hook produces relative rotation between the drag hook under the drive that plate is turned round.
Other characteristics of this utility model are: one of them is fixed in elevating lever bottom described a pair of drag hook, another root drag hook through be positioned at elevating lever connecting rod be connected with a pair of bevel gear, the bevel gear on the connecting rod is turned round with plate and is linked to each other.
Described elevating lever is a pipe, and the internal diameter of its pipe is greater than the external diameter of T type bolt.
The special-purpose drag hook of the auxiliary little otch thyroid operation of the chamber mirror of this utility model, compared with prior art, bring following beneficial effect:
Adopt draw-in groove and operation table to carry out effectively fixing; Simultaneously drag hook can carry out the adjusting of tractive intensity and tractive scope as required, has flexible, reliable characteristics, has both satisfied the needs that thyroid operation under the different situations is built the chamber; Do not need the assistant to continue tractive again; Save manpower, convenient operation is raised the efficiency.
