Description
Technical field
This utility model relates to a kind of surgery and uses medical apparatus and instruments, relates in particular to a kind of bending-type pin cutter.
Background technology
Pin cutter therapy is a kind of closure lysis between operative therapy and non-operative treatment, and it is mainly used in soft tissue injury pathological changes and osteoarthrosis.Because pin cutter therapy is the operation treatment of under the situation of non-direct-view, carrying out; Be unfamiliar with if treat the position of dissection, maneuver is improper, causes damage easily; Especially when the treatment osteoarthrosis; In the time of need carrying out strip operation such as the pinch spalling in deep, horizontal stripping and vertical stripping, very easily damage tissues such as ligament, tendon, this has just proposed high request to osteoarticular pin cutter therapeutic kit.
The Chinese patent Granted publication number is CN201394052Y, and Granted publication day is that the utility model patent on February 3rd, 2010 discloses a kind of novel small needle knife, comprises handle, the needle body, pin cutter three parts; Pin cutter width generally equates with diameter of needle body; Cutting edge is sharp, and the point of a knife angle is an acute angle, and pin cutter blade is not a straight line; Be the setback line, the angle of setback line is the obtuse angle.Though this utility model can alleviate patient's pain when carrying out strip operation, and has avoided the damage or the cut-out of ligament, tendon etc. to a certain extent, its blade structure is fixed; Can not cut the stripping angle according to what the practical situation of osteoarthrosis tissue changed blade, adjustability is relatively poor, and; Its blade has only a side to be provided with to cut the cutting edge and the point of a knife of stripping usefulness; It is relatively poor not only to cut the stripping effect, and is prone to blocked by tissue, increases operation easier.
Summary of the invention
The purpose of this utility model be overcome the adjustability that exists in the prior art relatively poor, cut stripping effect is relatively poor, operation easier is bigger defective and problem, provide a kind of adjustability strong, cut the stripping bending-type pin cutter that effect is better, operation easier is less.
For realizing above purpose, the technical solution of this utility model is: a kind of bending-type pin cutter, comprise interconnective handle and cutter hub, and an end of said cutter hub is connected with handle, and the other end is provided with point of a knife; One end of said handle is provided with the external screw thread hole, and the other end of handle is connected with the bending handle, and the other end of bending handle is connected with cutter hub.
The manufactured materials of said bending handle is stress property plastics.
Said cutter hub comprises that into a single integrated structure master cuts portion and pair is cut portion, and a main end of cutting portion is provided with point of a knife, and the other end is connected with the pair portion of cutting, and the other end that pair is cut portion is connected with the bending handle.
The both sides that said master cuts portion are provided with arcual main left cut sheet and main right cut sheet, and the both sides that pair is cut portion are provided with arcual secondary left cut sheet and secondary right cut sheet, and the camber of main left cut sheet is lower than the camber of main right cut sheet, and the camber of secondary left cut sheet is higher than the camber of secondary right cut sheet.
Compared with prior art, the beneficial effect of this utility model is:
1, the end owing to handle in a kind of bending-type pin of this utility model cutter is provided with the external screw thread hole, and the other end of handle is connected with the bending handle, and the other end of bending handle is connected with cutter hub; And the manufactured materials of bending handle is stress property plastics, and during use, what can change blade through the stress property twisting of bending handle cuts the stripping angle; Thereby improve the specific aim and the efficient of cutting stripping; And the external screw thread hole that an end of handle is provided with can external ancillary equipment, thereby improves the effect of pin cutter treatment.Therefore not only adjustability is stronger for this utility model, and it is better to cut the stripping effect.
2, because the cutter hub in a kind of bending-type pin of this utility model cutter comprises that into a single integrated structure master cuts portion and pair is cut portion; Main both sides of cutting portion are provided with arcual main left cut sheet and main right cut sheet, and the both sides that pair is cut portion are provided with arcual secondary left cut sheet and secondary right cut sheet, and the camber of main left cut sheet is lower than the camber of main right cut sheet; The camber of secondary left cut sheet is higher than the camber of secondary right cut sheet; During use, not only stripping all can be cut in the both sides of cutter hub, cut the stripping effect stronger; And can cut on the basis of shelling effect in raising through the mutual coordination of main left cut sheet, main right cut sheet and secondary left cut sheet, secondary right cut sheet and reduce operation easier, effectively avoid cutter hub to be blocked by the osteoarthrosis tissue.Therefore it is better that this utility model is not only cut the stripping effect, and operation easier is less.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Among the figure: handle 1, external screw thread hole 11, cutter hub 2, point of a knife 3, bending handle 4, the master cuts portion 5, main left cut sheet 51, main right cut sheet 52, pair is cut portion 6, secondary left cut sheet 61, secondary right cut sheet 62.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment this utility model is done further detailed explanation
Referring to Fig. 1, a kind of bending-type pin cutter comprises interconnective handle 1 and cutter hub 2, and an end of said cutter hub 2 is connected with handle 1, and the other end is provided with point of a knife 3; One of special feature of this utility model is: an end of handle 1 is provided with external screw thread hole 11, and the other end of handle 1 is connected with bending handle 4, and the other end of bending handle 4 is connected with cutter hub 2.The manufactured materials of preferred bending handle 4 is stress property plastics.What the stress property design of bending handle 4 was convenient to select cutter hub 2 cuts the stripping angle, and pin cutter external ancillary equipment is convenient in the design in external screw thread hole 11, thereby improves the effect of pin cutter treatment.
Preferred cutter hub 2 comprises that into a single integrated structure master cuts portion 5 and cuts portion 6 with pair, and a main end of cutting portion 5 is provided with point of a knife 3, and the other end is cut portion 6 with pair and is connected, and the other end that pair is cut portion 6 is connected with bending handle 4; Further preferred main both sides of cutting portion 5 are provided with arcual main left cut sheet 51 and main right cut sheet 52; The both sides that pair is cut portion 6 are provided with arcual secondary left cut sheet 61 and secondary right cut sheet 62; And the camber of main left cut sheet 51 is lower than the camber of main right cut sheet 52, and the camber of secondary left cut sheet 61 is higher than the camber of secondary right cut sheet 62.This design can make the both sides of cutter hub 2 all can cut stripping; It is stronger to cut the stripping effect; And can effectively avoid cutter hub 2 to be blocked, thereby reduction operation difficulty through the mutual coordination of main left cut sheet 51, main right cut sheet 52 and secondary left cut sheet 61, secondary right cut sheet 62 by the osteoarthrosis tissue.
Therefore not only adjustability is strong, to cut the stripping effect better for this utility model, and simple in structure, operation easier is less.
The above is merely the preferred embodiments of this utility model; The protection domain of this utility model does not exceed with above-mentioned embodiment; As long as the equivalence that those of ordinary skills do according to this utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
