Abstract

The invention relates to the technical field of medical instruments, in particular to an anal fistula scalpel. The anal fistula scalpel comprises an inner prying part and an outer prying part. The outer prying part comprises an outer scalpel pipe and an outer scalpel handle, and the upper end of the outer scalpel pipe is provided with a spiral opening. The inner prying part comprises an inner scalpel pipe and an inner handle. The top end of the outer scalpel pipe and the top end of the inner scalpel pipe are provided with round heads. The upper end of the inner scalpel pipe is provided with a spiral opening the same as the spiral opening in the outer scalpel pipe. The spiral opening in the outer scalpel pipe and the spiral opening in the inner scalpel pipe are provided with scalpel edges. The inner scalpel pipe can move up and down and freely rotate by 360 degrees in the outer scalpel pipe. The spiral openings are provided with smooth threads or toothed threads. The lower end of the outer scalpel pipe and the lower end of the inner scalpel pipe are provided with curve rods. The curve rods are provided with thread lines. The diameter of the outer scalpel pipe and the diameter of the inner scalpel pipe range from 1 mm to 5 mm, and the screw pitches of the spiral openings range from 2.5 mm to 4.5 mm and are equidistant pitches or big-end-up gradually-changing screw pitches. The outer scalpel pipe and the inner scalpel are provided with scale marks. The anal fistula scalpel can freely carry out 360-degree dead-angle-free cutting, segmented cutting is achieved, labor is saved during manual cutting, the anal fistula scalpel is close to clinic use, the operation fatigue of medical workers is relieved, and the excision efficiency is higher.

Description

Anal fistula operating knife

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 using on clinical medicine is generally needle type inner edge cutting knife.In therapeutic process, after finding fistula road internal orifice, the special-purpose probe of needs with Anal fistula scalpel, performs the operation again, exist the shortcomings such as operation inconvenience; Sometimes need directly with Anal fistula scalpel, to find internal orifice, but extremely easily damage other positions, cause unnecessary damage, even operative failure.

The anal fistula operating knife that also has at present a kind of steel pipe type, the notch on pipe is all level, can upper and lower staggered floor when this has just caused cutting, alignment precision is not high, and has dead angle to exist, if the knife back leans against above meat tissue, just has no idea to cut.

Summary of the invention

In order to overcome existing above-mentioned deficiency, 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, comprise interior sled and outer sled, outer sled comprises outer cutter pipe and outer handle of a knife, outer cutter pipe upper end is provided with spiral opening, interior sled comprises interior cutter pipe and inner handle, outer cutter pipe and interior cutter pipe top are provided with round end, interior cutter pipe upper end be provided with outer cutter pipe on identical spiral opening, the spiral opening of outer cutter pipe and interior cutter pipe is provided with the edge of a knife, interior cutter pipe can insert in outer cutter pipe, and interior cutter pipe moves up and down and any 360 ° of rotations in cutter pipe outside.

According to another embodiment of the invention, further comprise that spiral opening is provided with smooth screw thread or band tooth thread.

According to another embodiment of the invention, further comprise that outer cutter pipe and interior cutter pipe lower end are provided with bent stick, bent stick is provided with threaded line.

According to another embodiment of the invention, the diameter that further comprises outer cutter pipe and interior cutter pipe is 1-5mm.

According to another embodiment of the invention, the pitch that further comprises the spiral opening of outer cutter pipe and interior cutter pipe is 2.5-4.5mm.

According to another embodiment of the invention, further comprise that pitch is equidistant pitch or up big and down small gradient pitch.

According to another embodiment of the invention, further comprise that outer cutter pipe and interior cutter pipe are provided with graduation mark.

The invention has the beneficial effects as follows, can be any 360 ° without dead angle cutting, realize segmentation cutting, torsional forces is little, manually cuts laborsavingly, approach clinic is used, and reduces medical personnel's operation fatigue, excision efficiency is higher.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is further described.

Fig. 1 is with smooth screw thread to prize structural representation outward;

Fig. 2 is with sled structural representation in smooth screw thread;

1. interior sleds in figure, 2. outer sled, 3. outer cutter pipe, 4. outer handle of a knife, 5. interior cutter pipe, 6. inner handle, 7. smooth screw thread, 8. band tooth thread, 9. bent stick, 10. sealing thread, 11. graduation marks, 12. round ends.

The specific embodiment

If Fig. 1-Fig. 6 is structural representation of the present invention, a kind of anal fistula operating knife, comprise interior sled 1 and outer sled 2, outer sled 2 comprises outer cutter pipe 3 and outer handle of a knife 4, outer cutter pipe 3 upper ends are provided with spiral opening, interior sled 1 comprises interior cutter pipe 5 and inner handle 6, outer cutter pipe 3 and interior cutter pipe 5 tops are provided with round end 12, interior cutter pipe 5 upper ends be provided with outer cutter pipe 3 on identical spiral opening, the spiral opening 6 of outer cutter pipe 3 and interior cutter pipe 5 is provided with the edge of a knife, in interior cutter pipe, cutter pipe can insert in outer cutter pipe 3, interior cutter pipe 5 moves up and down and any 360 ° of rotations in cutter pipe 3 outside, spiral opening is provided with smooth screw thread 7 or band tooth thread 8, outer cutter pipe 3 and interior cutter pipe 5 lower ends are provided with bent stick 9, bent stick 9 is provided with threaded line 10, the diameter of outer cutter pipe 3 and interior cutter pipe 5 is 1-5mm, the pitch of the spiral opening of outer cutter pipe 3 and interior cutter pipe 5 is 2.5-4.5mm, pitch is equidistant pitch or up big and down small gradient pitch, outer cutter pipe 3 and interior cutter pipe 5 are provided with graduation mark 11.

This scalpel is applicable to the anal fistula cutting operation in surgical operation, using method is very simple, first outer sled (2) is inserted as in the tissue of required cutting, insertion depth can be reflected very intuitively by graduation mark (11), and this scalpel top adopts round end 12 designs, secondary injury in the time of can avoiding inserting, then Inner sled (1) is inserted in outer sled (2), rotation Inner sled (1), owing to having the edge of a knife on internal and external screw opening, by turning effort power, realize the cutting of pathological tissues.

Below provide specific embodiment:

One, be as shown in Figure 1, Figure 2 the anal fistula operating knife of the smooth screw thread of a cuff, this scalpel is the most conventional a kind of, easy to usely can realize glossy cut.

Two, as Fig. 3, Fig. 4, be the anal fistula operating knife of a cuff gear screw thread, this scalpel can be realized segmentation cutting, and due to band gear screw thread, during cutting, torsional forces is large, manually uses more laborsavingly, if cooperative mechanical equipment is used, can reduce costs.

Three, if Fig. 5, Fig. 6 are a cuff gear screw thread and the anal fistula operating knife of distorting bar, this scalpel more approach clinic is used, and reduces medical personnel's operation fatigue.

Above three cover scalpels can both be realized any 360 ° and cut without dead angle, and work efficiency is very high.

More than explanation is just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skills understand, in the situation that do not depart from the spirit and scope that claims limit; can make many modifications, variation or equivalence, but all will fall within the scope of protection of the present invention.
