Description
Technical field
The present invention relates to technical field of medical instruments, especially a kind of anal fistula operating knife.
Background technology
Nowadays the anal fistula operating knife used on clinical medicine generally needle type inner edge cutting knife.Over the course for the treatment of, need
Special probe is wanted to be performed the operation again with Anal fistula scalpel after finding fistula road internal orifice, the shortcomings of there is operation inconvenience；Sometimes for straight
Connect and find internal orifice with Anal fistula scalpel, but extremely easily damage other positions, cause unnecessary damage, or even operative failure.
It is all horizontal to also have the notch on a kind of anal fistula operating knife of steel pipe type, pipe at present, and which results in during cutting
Staggered floor above and below meeting, alignment precision is not high, and with the presence of dead angle, if the knife back is leaned against above meat tissue, just has no idea to carry out
Cutting.
The content of the invention
Existing above-mentioned in order to overcome the shortcomings of, the invention provides a kind of anal fistula operating knife.
The technical solution adopted for the present invention to solve the technical problems is：A kind of anal fistula operating knife, including interior sled and outer sled,
Outer sled includes outer knife pipe and outer handle of a knife, and outer knife pipe upper end is provided with spiral opening, and interior sled includes interior knife pipe and inner handle, outer knife pipe with
Interior knife tube top end is provided with round end, interior knife pipe upper end be provided with and outer knife pipe on identical spiral opening, the spiral shell of outer knife pipe and interior knife pipe
Mouth is outwarded winding provided with the edge of a knife, interior knife pipe is inserted into outer knife pipe, and interior knife pipe can be moved up and down and any 360 ° in outer knife pipe
Rotation.
According to another embodiment of the invention, further comprise spiral opening provided with smooth thread or with tooth thread.
According to another embodiment of the invention, further comprise that outer knife pipe and interior knife pipe lower end are provided with bent stick, bending
Bar is provided with threaded line.
According to another embodiment of the invention, a diameter of 1-5mm of outer knife pipe and interior knife pipe is further comprised.
According to another embodiment of the invention, the pitch for further comprising the spiral opening of outer knife pipe and interior knife pipe is
2.5-4.5mm。
According to another embodiment of the invention, it is equidistant pitch or up big and down small gradual change spiral shell to further comprise pitch
Away from.
According to another embodiment of the invention, further comprise that outer knife pipe and interior knife pipe are provided with graduation mark.
The beneficial effects of the invention are as follows, can any 360 ° without dead angle cutting, realize segmentation cutting, torsional forces is small, manually
Cutting is laborsaving, and approach clinic is used, and reduces the operation fatigue of medical personnel, cuts off more efficient.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is to prize structural representation outside band smooth thread；
Fig. 2 is sled structural representation in band smooth thread；
Fig. 3 is to prize structural representation outside band gear screw thread；
Fig. 4 is sled structural representation in band gear screw thread；
Fig. 5 is to prize structural representation outside band gear screw thread and distortion bar；
Fig. 6 is band gear screw thread and distorts sled structural representation in bar.
Prized in 1. in figure, 2. outer sleds, 3. outer knife pipes, 4. outer handle of a knifes, knife pipe, 6. inner handles, 7. smooth threads, 8. bands in 5.
Tooth thread, 9. bent sticks, 10. sealing screw threads, 11. graduation marks, 12. round ends.
Embodiment
If Fig. 1-Fig. 6 is the structural representation of the present invention, a kind of anal fistula operating knife, including interior sled 1 and outer sled 2, outer sled 2
Including outer knife pipe 3 and outer handle of a knife 4, the outer upper end of knife pipe 3 is provided with spiral opening, and interior sled 1 includes interior knife pipe 5 and inner handle 6, outer knife pipe
3 and the interior top of knife pipe 5 be provided with round end 12, the interior upper end of knife pipe 5 be provided with and outer knife pipe 3 on identical spiral opening, outer knife pipe 3 and interior
The spiral opening 6 of knife pipe 5 is provided with knife pipe in the edge of a knife, interior knife pipe and is inserted into outer knife pipe 3, and interior knife pipe 5 can be in outer knife pipe 3
Move up and down and be provided with smooth thread 7 or with tooth thread 8, outer knife pipe 3 and the interior lower end of knife pipe 5 with any 360 ° rotations, spiral opening
Provided with bent stick 9, bent stick 9 is provided with a diameter of 1-5mm of threaded line 10, outer knife pipe 3 and interior knife pipe 5, outer knife pipe 3 and interior knife
The pitch of the spiral opening of pipe 5 is 2.5-4.5mm, and pitch is equidistant pitch or up big and down small gradient pitch, the outer He of knife pipe 3
Interior knife pipe 5 is provided with graduation mark 11.
This scalpel is adapted to the anal fistula cutting operation in surgical operation, and application method is very simple, first by outer sled（2）Insert
In the required tissue cut, insertion depth can be by graduation mark（11）Intuitively reflect very much, the scalpel top is used
Round end 12 is designed, and can be avoided secondary injury during insertion, then be prized Inner（1）Insertion is outer to prize（2）In, rotation Inner sleds（1）, by
In having the edge of a knife in internal and external screw opening, by rotating force, the cutting of pathological tissues is realized.
Specific embodiment given below：
First, it is the anal fistula operating knife of a cuff smooth thread as shown in Figure 1, Figure 2, this scalpel is most conventional one kind, is made
Glossy cut can be realized with convenient.
2nd, such as Fig. 3, Fig. 4 are the anal fistula operating knife of a cuff gear screw thread, and this scalpel can realize segmentation cutting,
Due to band gear screw thread, torsional forces is big during cutting, manually uses than relatively labor-saving, can if cooperative mechanical equipment is used
Reduce cost.
3rd, such as Fig. 5, Fig. 6 are a cuff gear screw thread and the anal fistula operating knife for distorting bar, and this scalpel more is pressed close to face
Bed is used, and reduces the operation fatigue of medical personnel.
Three sets of scalpels of the above can realize any 360 ° without dead angle cutting, and operating efficiency is very high.
It is described above to be merely exemplary for the purpose of the present invention, and it is nonrestrictive, and those of ordinary skill in the art understand,
In the case where not departing from the spirit and scope that appended claims are limited, many modifications, change or equivalent can be made, but all
