Abstract
The utility model discloses a novel trephine comprising trephine, wherein saw teeth are formed at one end of the saw rod of the trephine and the saw rod is shaped like a hollow tube. The novel trephine is characterized by further comprising a handle, wherein the handle is arranged at the other end of the saw rod and fixedly connected to the outer wall surface of the saw rod. The novel trephine is provided with the handle so that the trouble that the handle and the saw rod should be matched and connected with each other before use in operation is avoided; the novel trephine is simple in structure, convenient for carrying and use and easy to operate; and the operation time is shortened, the working efficiency is improved and the operation risk is reduced.
Description
Technical field
This utility model relates to a kind of trepan, and particularly a kind of convenient Novel trephine that uses belongs to medical instruments field.
Background technology
When the treatment intervertebral disc prolapse, in the situation that intervertebral disk hernia will use trepan that the intervertebral disc vertebra is punched.Present employed trepan has the plurality of specifications that varies in size, saw rod and handle separately, so saw rod and handle could use in operation after will assembling when using temporarily, this trepan assembles loaded down with trivial details and expends time in, the unstable possibility of assembling is more arranged, making operation have security risk.
The utility model content
The utility model proposes a kind of Novel trephine, solved the problem that the saw rod of trepan needs first and the handle assembling could be used in the prior art, for the time has been saved in operation, and be convenient for carrying and use.
The technical solution of the utility model is achieved in that and comprises trepan, saw rod one end of described trepan is provided with sawtooth and is hollow tubular, it is characterized in that: described trepan also comprises one handle, and the other end of described saw rod is provided with handle, and the outside wall surface of handle and saw rod is affixed.Saved on the one hand the trouble that need to first handle be connected with saw rod when operation is used, no longer needed it is dismantled packing after trepan uses on the other hand, carried with more convenient to use.
Described trepan is provided with a distance keeper, and described distance keeper is enclosed within the outer surface of described saw rod, and can be by tight shelves fastening nuts.Described distance keeper can move freely at the saw rod outer surface, behind tight shelves fastening nuts, and the degree of depth that pierces when limiting operation.
Described trepan is provided with an obturator that is inserted in described hollow saw rod, and described obturator is the elongated rod shape that enlarged head is arranged.
Described handle and saw rod are by being welded and fixed.
The saw rod outer surface of described trepan has scale near an end of sawtooth, and described scale indicates corresponding scale value.
The beneficial effect that the utlity model has is: simple in structure, easy operating; The saw rod that links into an integrated entity and handle have saved on the one hand and saw rod and handle need to have been coupled together the trouble that could use, no longer need it is dismantled packing after trepan uses on the other hand, carry with more convenient to use.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Trepan as shown in Figure 1 comprises trepan, and saw rod 4 one ends of trepan are provided with sawtooth 5 and are hollow tubular, and trepan also comprises one handle 2, and the other end of saw rod 4 is provided with handle 2, and handle 2 is affixed with the outside wall surface of saw rod 4.Having saved on the one hand when operation is used needs first handle 2 to be connected with saw rod the trouble that connects, and no longer needs it is dismantled packing after trepan uses on the other hand, carries with more convenient to use.
Trepan is provided with a distance keeper 6, and distance keeper 6 is enclosed within the outer surface of saw rod 4, and can be fastening by tight shelves nut 1.Distance keeper 6 can move freely at saw rod 4 outer surfaces, fastening by tight shelves nut 1 after, the degree of depth that pierces when limiting operation.
Trepan is provided with an obturator 3 that is inserted in the hollow saw rod 4, and obturator 3 is for there being the elongated rod shape of enlarged head.
Handle 2 and saw rod 4 are by being welded and fixed.
Saw rod 4 outer surfaces of trepan have scale near an end of sawtooth 5, and described scale indicates corresponding scale value.
The specific operation process of the present embodiment is as follows:
When performing the operation to patient, mix up the position of distance keeper 6 on saw rod 4 according to target scale value on the saw rod 4, the tight shelves of twisting nut 1 is fixing, and the doctor holds handle 2, the manual pressure rotary-cut, thus reach purpose to the vertebra perforate.
The above only is preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
