Description
Technical field
The present invention relates to a kind of surgical knife tool, specifically a kind of cutter for Hysterectomy belongs to Medical treatment device
Tool field.
Background technology
Hysterectomy approach has through abdomen, Via vagina and laparoscope etc., compared with classical abdominal hysterectomy, female
Uterectomy and laparoscopically hysterectomy have that wound is small, it is acceptant to restore advantages, the patient such as fast.Female uterus simultaneously
Resection is small there are surgical field of view, exposure and operating difficulties, easily the shortcomings of damage adjacent organ.Therefore, also derive in recent years
Go out some and special equipment, such as Patent No. 20,102,021 6262.9 are matched with minimally invasive uterectomy, it is entitled cup type
The invention of uterus raising device can play good effect in surgical procedure.Presently relevant derivative instrument is primarily directed to uterus
With the separation of surrounding tissue, and clinically often occur cannot directly be taken out since the palace body after separation is excessive by vagina, and will first
The situation that fritter takes again is shredded into, the time needed is long, and the heavy workload of doctor, effect is also bad, easily encounters adjacent organ.
Invention content
The object of the present invention is to provide a kind of cutters for Hysterectomy, can more efficient, easily chopping, taking-up
Gong Ti greatly shortens operating time, mitigates patient's pain.
In order to achieve the above object, the present invention adopts the following technical scheme that：A kind of cutter for Hysterectomy,
Cutter including handle of a knife and on the handle of a knife, which is characterized in that the cutter includes knife spine portion and by the knife spine portion
Extend outward for cutting at least one blade part in uterus, the blade part along the vertical axes with the handle of a knife it
Between make an angle alpha central shaft helical form setting, the angle α be obtuse angle.
Strip is cut into the uterus detached with surrounding tissue by the technical solution by spiral helicine cutter, successfully from
Vagina takes out, and more rapidly, operating time is greatly saved in cutting.
Longitudinal direction is formed preferably, the blade part at least two, between adjacent blade part leads to the handle of a knife
The vertical passage in direction.
The number of blade part determines the speed of cutting, and vertical passage plays guiding role, the bar cut along
Vertical passage skids off, and not only can smoothly export bar, but also can improve the efficiency of cutting.
Preferably, the blade forms a breakthrough top at the top of cutter, the top of the blade part is described
Top is broken through to accumulate a little.Convenient for quickly finding the starting point of cutting.
Preferably, the spiral angle of the blade part is gradually reduced by top to described handle of a knife one end of cutter.
Spiral angle is big, cutting it is fast, but angle is big, is easily wrapped on blade, it is not easy to export bar, spiral
Angle gradually increases with export direction, and cutting is completed in the small upstream of angle, continue thereafter with thoroughly cutting open bar and with
Vertical passage export.
Preferably, the width of the vertical passage is gradually increased by top to described handle of a knife one end of cutter, ensure item
Shape object smoothly exports.
Preferably, the channel surface of the vertical passage is in smooth arc, the bar export efficiency cut is increased.
Preferably, the angle α is 120-135 °, it is conveniently operated.
Preferably, the blade part is 2-4, blade part can influence to cut effect very little, can lead to uterus meeting too much
It is wrapped on blade, influences extraction efficiency.
Preferably, structure, cutting, export effect are good in the form of sheets for the cutter.
Preferably, being equipped with connecting neck portion between the handle of a knife and the cutter, coordinate the length of vagina, be conveniently operated,
It will not cause suffering again to patient, the cutter is mounted on by the connecting neck portion on the handle of a knife.
By implementing above-mentioned technical proposal, the present invention has the advantages that：The present invention is rational in infrastructure, easy to operate,
Situation is not easily taken out of for palace body is larger, the present invention can be shredded efficiently, take out palace body, substantially increase procedure efficiency,
Mitigate the pain of patient.
Description of the drawings
Attached drawing 1 is the structure diagram of the embodiment of the present invention 1；
Attached drawing 2 is the structure diagram of the embodiment of the present invention 2；
Attached drawing 3 is the structure diagram of the embodiment of the present invention 3.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the present invention is described in further detail.
Embodiment 1：
Cutter as shown in Figure 1, for Hysterectomy, sheet including handle of a knife 1 and on handle of a knife 1 is cut
Knife 2, cutter 2 include knife spine portion 21 and two blade parts 22 for being used to cut uterus extended outward by knife spine portion 21, knife
The setting of central shaft helical form that blade 22 makes an angle alpha between the vertical axes along handle of a knife 1, the angle α are obtuse angle, this implementation
Example is 135 °, and the spiral angle of blade part 22 is gradually reduced by top to 1 one end of handle of a knife of cutter；Adjacent blade part 22
Between formed longitudinal direction lead to 1 direction of handle of a knife channel surface be in smooth arc vertical passage 23.Blade 2 is on the top of cutter
Portion forms a breakthrough top 24, and the top of blade part 22 accumulates a little on breakthrough top 24.
Embodiment 2：
As shown in Figure 2 be used for Hysterectomy cutter, including handle of a knife 1, the connecting neck portion on handle of a knife 2 and
The sheet cutter 2 integral with connecting neck portion, cutter 2 include knife spine portion 21 and are used to cut by what knife spine portion 21 extended outward
Cut three blade parts 22 in uterus, blade part 22 along the angle α between the vertical axes of handle of a knife 1 being in 110 ° central shaft spiral
Shape is set, and the spiral angle of blade part 22 is gradually reduced by top to 1 one end of handle of a knife of cutter；Adjacent blade part 22 it
Between form the vertical passage 23 for leading to 1 direction of handle of a knife of longitudinal direction, width gradually increases by top to 1 one end of handle of a knife of cutter.
