Abstract
The utility model discloses a kind of rotating suction circular cutter, comprise presoma and opisthosoma, the two is hollow tubular structure, and two tube chambers are coaxial; Presoma inner wall at end is provided with stepped hole, and this stepped hole comprises first step hole and second step hole, and first step Kongzui major diameter is less than second step Kongzui minor diameter; Presoma top is provided with cutting knife; Opisthosoma comprises leading portion, stage casing and back segment; Leading portion inserts in second step hole, and the two can matched in clearance with the relative rotation.In use, doctor can attract by limit cutting edge when surgical cut operates this utility model, remains that visual area is clear.Relatively can rotate between presoma and opisthosoma, no matter doctor is cutting when operating or attracts all can rotate freely operation, increase operation technique scope, make operation easier.This utility model is very easy to and operates in the art under endotoscpe, saves operating time, is conducive to improving procedure efficiency.
Description
Technical field
This utility model relates to a kind of circular cutter, specifically a kind of circular cutter of rotatable band suction function.
Background technology
At present, during ear operation, cut skin many uses circular cutter of bony auditory canal, the hemorrhage operation that can affect doctor in visual area after cutting.When doctor carries out tympanum repairing or tympanotomy, while one-handed performance, also require that visual area is clear.
In the prior art, once occur that visual area is unintelligible and will change suction pump immediately and attract during operation, until recover visual area clear after gain circular cutter again and continue operation.An operation often needs frequently to change circular cutter and suction pump, and not only operation technique is complicated, and operating time can extend.In addition, it is that suction pump cannot rotate freely that prior art also exists a problem, and suction pump leather strap also needs after screwing to reversely rotate recovery ortho states in use, doctor's opereating specification is obstructed, reduces procedure efficiency.
How to solve above-mentioned the problems of the prior art, be the focus that those skilled in the art study always.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of when performing the operation ring cutting operation, can clear up visual area dirt at any time and rotatable attraction circular cutter.
For achieving the above object, this utility model adopts following technical scheme:
A kind of rotating suction circular cutter, comprise presoma and opisthosoma, the two is hollow tubular structure, and two tube chambers are coaxial; Described presoma inner wall at end is provided with stepped hole, and this stepped hole comprises first step hole and second step hole, and the maximum gauge in described first step hole is less than the minimum diameter in second step hole; Described presoma top is provided with cutting knife; Described opisthosoma comprises leading portion, stage casing and back segment; Described leading portion inserts in described second step hole, and the two can matched in clearance with the relative rotation.
Wherein more preferably, described presoma is tapered structure.
Wherein more preferably, the first step hole of described presoma is bellmouth, and top end diameter is less than end diameter.
Wherein more preferably, the second step hole of described presoma is bellmouth, and top end diameter is less than end diameter.
Wherein more preferably, the angle between the top through hole place plane of described presoma and described cutting knife place plane is 50 ~ 130 degree.
Wherein more preferably, the top through hole of described presoma and described cutting knife are positioned at same plane.
Wherein more preferably, the stage casing external diameter of described opisthosoma is identical with the maximum outside diameter of described presoma.
Wherein more preferably, described opisthosoma back segment outer wall is provided with some boss or convex ridge that can be connected with suction pump leather strap.
Wherein more preferably, described presoma outer wall is provided with anti-skid structure.
Wherein more preferably, described rotating suction circular cutter is made up of stainless steel.
In use, doctor can attract by limit cutting edge when surgical cut operates this utility model, remains that visual area is clear.Presoma and opisthosoma can rotate therebetween relatively, no matter doctor is cutting when operating or attracts all can rotate freely operation, increase operation technique scope, make operation easier.This utility model is very easy to and operates in the art under endotoscpe, saves operating time, is conducive to improving procedure efficiency.

Detailed description of the invention
Embodiment 1
As shown in Fig. 1 to 5, a kind of rotating suction circular cutter, comprise presoma 1 and opisthosoma 2, the two is hollow tubular structure, and two tube chambers are coaxial; Presoma 1 is tapered structure, and inner wall at end is provided with stepped hole, and first step hole 11 maximum gauge is less than second step hole 12 minimum diameter, and first step hole 11 is bellmouth, and top end diameter is less than end diameter.Second step hole 12 is bellmouth, and top end diameter is less than end diameter; Presoma 1 top is provided with cutting knife 13.
As shown in Figure 3, the angle α between the top through hole 14 place plane A of presoma 1 and cutting knife 13 place plane B is 50 ~ 130 degree, is 62.42 degree in the present embodiment.
Opisthosoma 2 comprises leading portion 21, stage casing 22 and back segment 23; Leading portion 21 inserts in described second step hole 12, the two matched in clearance that can relatively rotate.Stage casing 22 external diameter is identical with presoma 1 maximum outside diameter.
Opisthosoma 2 back segment 23 outer wall is provided with some boss 24 that can be connected with suction pump leather strap.
Presoma 1 outer wall is provided with anti-skid structure 15.
This rotating suction circular cutter is made up of stainless steel, facilitates high-temperature sterilization.
Suction pump leather strap in use, is connected with the back segment 23 of opisthosoma 2 by this utility model, and opisthosoma's leading portion 21 inserts in presoma second step hole 12, is fixed together between the body of front and back by suction pump negative pressure.Doctor is when using cutting knife resection organization thing, and the tissue substances such as blood stains enter presoma top through hole, are entered in suction pump by presoma and opisthosoma.Like this, can ensure that the definition of visual area in art is again without the need to frequently changing operating theater instruments at any time.In addition, doctor, operating cutting step and attracting can rotate presoma and/or opisthosoma as required at any time during step, adds range of operation and flexibility ratio.
Embodiment 2
As shown in Figure 6, wherein presoma 1 top through hole and cutting knife 13 are positioned at same plane.Other structures are with embodiment 1.
