Description
This utility model relates to a kind of multi-functional controlled scalpel.
In the ophthalmologic operation, especially whether the otch of operation on eyeball is neat at present, and whether the depth is suitable, directly influence the effect of operation, but it is very difficult to carry out operation with present ophthalmology scalpel, needs very high medical skill, but careless slightly in the operation technique, will cause failure.
The purpose of this utility model provides the multi-functional controlled scalpel of a kind of easy to use, handling safety, simple, operative incision depth controlled.
This utility model is made up of handle of a knife and blade two parts, described handle of a knife is made up of for two sections front and back, leading portion is one with the back segment socket and can rotates relatively, the back segment inner chamber has female thread, and blade is flush-mounted in the handle of a knife, and the tail end of blade has and the identical external screw thread of the screw thread of handle of a knife back segment inner chamber, the blade tail end is threaded onto in the screw thread of handle of a knife back segment inner chamber, the sword sheet point of a knife of blade front end passes from handle of a knife leading portion head, and when the rotation handle of a knife, blade can stretch out in handle of a knife or indentation.
The head of above-mentioned handle of a knife leading portion can be provided with micro lighting lamp (7), is provided with corresponding battery in the handle of a knife, also can establish an ironing head at the head of handle of a knife rear end, and heater element is arranged in the ironing head.
This practicality newly can be regulated the length that blade stretches out easily, cutting-up relievedly when performing an operation, the precise control of the edge of a knife depth, easy for operation, simple, as miniature light-emitting component being installed at the handle of a knife leading section, can throw light on when then performing the operation, as load onto miniature ironing head, also can do haemostat when then performing the operation and use.
Below in conjunction with accompanying drawing this utility model is described further.
