Abstract
The invention discloses a cannula scalpel. The cannula scalpel comprises a scalpel head, a scalpel body and a cannula. The cannula is of a cylinder shape, one end of the cannula is opened, and the other end of the cannula is closed. The scalpel body is of a flat cuboid shape, one end of the scalpel body is connected with the scalpel head, and the other end of the scalpel body stretches into the interior of the cannula from the open end of the cannula. A strip-shaped guide groove is formed in the axial direction of the surface of the cannula. Clamping grooves perpendicular to the guide groove are formed in the surface of the cannula at the two ends of the guide groove, and the clamping grooves are communicated with the guide groove. Clamping blocks are arranged above the tail of the scalpel body and can move in the clamping grooves and the guide groove back and forth. According to the cannula scalpel, when the scalpel needs to be rotated, the scalpel body can be freely shrunk in the cannula and clamped through the clamping grooves, when one-way stable cutting needs to be conducted, the scalpel body can be stretched out of the cannula and then clamped by the clamping grooves, and the cannula scalpel is flexible and convenient to use.
Description
Technical field
The present invention relates to technical field of medical instruments, relate in particular to a kind of sleeve pipe scalpel.
Background technology
In operation process, scalpel has become a kind of requisite medical apparatus and instruments, in the process of operation, may encounter the situation of various complexity, scalpel needs above-below direction to cut sometimes, need sometimes horizontal direction to cut, need sometimes scalpel to rotate, and the handle of a knife of traditional scalpel is all generally flat cuboid, very inconvenient when adjusting scalpel direction.
Summary of the invention
for the problems referred to above, the invention provides a kind of sleeve pipe scalpel, the design by sleeve pipe can allow blade free-extension, can be for need to scalpel being adjusted into different states under different situations.
Technical problem to be solved by this invention is achieved through the following technical solutions:
A kind of sleeve pipe scalpel, it is characterized in that: comprise cutter head, blade, sleeve pipe, described sleeve pipe one end opening, other end sealing, one end of described blade is connected with cutter head, the other end stretches into inside pipe casing from the opening of sleeve pipe, the guide groove that axially has strip is prolonged on the surface of described sleeve pipe, and the sleeve surface at guide groove two ends has the draw-in groove vertical with guide groove, and draw-in groove is connected with guide groove, above the afterbody of described blade, be provided with fixture block, fixture block can move around in draw-in groove and guide groove.
Preferably, described draw-in groove starts to be narrowed down by wide to the other end from the one end being connected with guide groove.
Preferably, described fixture block is cube shaped.
Preferably, between described cover inner casing tube bottom and blade afterbody, be provided with a constant force spring.
The beneficial effect that the present invention reaches is: when needs rotate scalpel, is free in blade retraction sleeve pipe and block by draw-in groove, when needs are done one way stable incision, blade can be stretched out to sleeve pipe and by draw-in groove, be blocked again, and flexible.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of sleeve pipe scalpel of the present invention.
The specific embodiment
In order to further describe technical characterstic of the present invention and effect, below in conjunction with the drawings and specific embodiments, the present invention is described further.
With reference to Fig. 1, a kind of sleeve pipe scalpel, comprise cutter head 1, blade 2, sleeve pipe 3, described sleeve pipe 3 is cylindrical, one end opening, other end sealing, described blade 2 is flat cuboid, one end is connected with cutter head 1, and the other end stretches into sleeve pipe 3 inside from the opening of sleeve pipe 3, and the guide groove 4 that axially has strip is prolonged on the surface of described sleeve pipe 3, sleeve surface at guide groove two ends has the draw-in groove vertical with guide groove 5, draw-in groove is connected with guide groove, is provided with fixture block 6 above the afterbody of described blade 2, and fixture block 6 can move around in draw-in groove 5 and guide groove 4.
Tighter for what allow fixture block 6 block in draw-in groove 5, described draw-in groove 5 starts to be narrowed down by wide to the other end from the one end being connected with guide groove 4.
In order to make slip and the screens of fixture block 6 more stable, described fixture block 6 is cube shaped.
Tighter and stable in the process of sliding for the card of fixture block 6, is provided with a constant force spring between described sleeve pipe 3 inner sleeve 3 bottoms and blade 2 afterbodys.
When using when needs scalpel is done unidirectional incision, blade 2 stretches out sleeve pipe 3, and fixture block 6 is snapped in the draw-in groove 5 of sleeve pipe upper end, in the time of need to rotating scalpel, the bottom that fixture block 6 is moved to guide groove 4 along guide groove 4 snaps in draw-in groove 5, and now blade 2 is also in retraction sleeve pipe 3.
Above-described embodiment does not limit the present invention in any form, all take to be equal to replace or technical scheme that the form of equivalent transformation obtains, within all dropping on protection scope of the present invention.
