Description
Technical field
The present invention relates to a kind of scalpel, relate in particular to a kind of scalpel with position limitation protection.
Background technology
Scalpel is the conventional surgical instrument of surgery, internal medicine, and any operation all must be used scalpel, and visible scalpel is the essential condition of operation, quite important.
Scalpel, because function is more single, does not structurally all have any more great reform all the time.Current scalpel generally comprises handle of a knife and blade, and blade is arranged on one end of handle of a knife, and during operation, doctor grasps handle of a knife, with blade periphery of diseased region with it the patient, cuts.The tissue of excision disease sites, or cut some tissue samples and chemically examine, analyze, finally to reach the object that makes Rehabilitation, this is also a kind of mode of the most effectively, the most directly curing the disease.
Current scalpel is not controlled the position limiting structure of the blade depth, and doctor relies on doctor's experience and maneuver by the depth of cutter, and the depth is difficult to accurate control, tends to occur that blade crosses shallow or excessively dark situation.During operation, blade is excessively shallow, does not reach cutting object or cutting effect, needs feed again again to cut, and to patient, increases unnecessary misery; And blade is excessively dark, can damage patient, to patient, increase unnecessary misery equally.Therefore, also there is safe and reliable not defect in current scalpel, and this is also the technical barrier of all the time expecting solution.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of scalpel with position limitation protection, and this scalpel with position limitation protection is easy to operate, more safe and reliable.The technical scheme adopting is as follows:
A scalpel with position limitation protection, comprises handle of a knife and blade, and blade is arranged on the lower end of handle of a knife, it is characterized in that: also comprise base plate, support, rotating shaft and at least one elevating mechanism; Support is arranged on base plate, and the upper end of support offers notch; The upper end of described handle of a knife is rotatably arranged in notch by rotating shaft; Described blade reaches base plate below from the edge of base plate; Elevating mechanism is arranged on base plate, and the clutch end of elevating mechanism is connected with the middle and lower part of handle of a knife.
Above-mentioned blade generally comprises the knife back and blade.
When performing the operation, first according to the needs of operation depth of cut, first by elevating mechanism, regulate blade and expose the size below base plate, then base plate is placed into patient's operative site with it, in feed, drag base plate slides on operative site, under the restriction of base plate, the degree of depth of feed is that blade exposes the size below base plate.By base plate, support and elevating mechanism are set, base plate forms supporting surface and the reference plane of scalpel, and by the adjusting of elevating mechanism, adjust the size that base plate below blade exposes, thereby limited the degree of depth of feed, avoided the too shallow or too dark situation of feed, performed the operation more accurate, reduce patient's misery, more safe and reliable, in addition, pass through elevating mechanism, can adjust at any time the size that blade exposes, according to the degree of depth that need to adjust at any time feed of operation.
As preferred version of the present invention, described elevating mechanism comprises screw rod, sleeve and locating dowel, and the medial wall of sleeve offers the screw thread matching with screw rod, on the medial wall, lower end of sleeve, offers annular slot, and the upper end of locating dowel is provided with at least two fixture blocks; The lower end of locating dowel is fixed on the upper surface of base plate; The lower end of sleeve is enclosed within locating dowel, and fixture block is in annular slot; The bottom of screw rod in sleeve, screw rod and threaded engagement; The upper end of screw rod and the middle and lower part of described handle of a knife are hinged.Pass through rotational sleeve, sleeve rotates around locating dowel, and due to the cooperation of fixture block and annular slot, sleeve and locating dowel can not be moved in the axial direction, when sleeve rotates, by the engagement of screw thread and screw rod, make screw rod and sleeve relative motion in the axial direction, be to make screw rod on above-below direction, do elevating movement, thereby drive the middle and lower part lifting of handle of a knife, adjust the gradient of handle of a knife, thereby adjusted blade, exposed the size below base plate, adjusted the degree of depth of operation feed.
As the further preferred version of the present invention, the outer end of described fixture block is sphere.The outer end of fixture block is set to sphere, and being slidably matched between fixture block and annular slot is better, more smooth and easy, prevents from, between fixture block and annular slot, stuck phenomenon occurs.
As the further preferred version of the present invention, the top of described screw rod is provided with station location marker line.By at screw rod top setting position tag line, from station location marker line, directly read the degree of depth of feed, convenient in operation, quick, also more accurate.
As preferred version of the present invention, described elevating mechanism comprises tooth bar, gear, tooth bar fairlead and rocking bar; The lower end of gear fairlead is fixedly mounted on described base plate; Gear is rotatably arranged in gear fairlead; One end of rocking bar is connected with the flank of tooth of gear; The bottom of tooth bar is in tooth bar fairlead, and rack and pinion is meshed; The upper end of tooth bar and the middle and lower part of described handle of a knife are hinged.By shaking rocking bar, gear is rotated, gear driven tooth bar is done oscilaltion campaign in tooth bar fairlead, thereby drive the middle and lower part lifting of handle of a knife, adjust the gradient of handle of a knife, thereby adjusted blade, exposed the size below base plate, adjusted the degree of depth of operation feed.
As the further preferred version of the present invention, the top of described tooth bar is provided with station location marker line.By at tooth bar top setting position tag line, from station location marker line, directly read the degree of depth of feed, convenient in operation, quick, also more accurate.
As preferred version of the present invention, the edge of described base plate is equipped with curve slope.By the edge at base plate, curve slope is set, reduces resistance, the movement of base plate on patient body can not be subject to the obstruction of gauffer on patient body, mobile very smooth and easy.
As preferred version of the present invention, the quantity of described elevating mechanism is two.The quantity of elevating mechanism is set to two, adopts at 3 blade holder is positioned, more stable, can not shake, and makes it possible to feed reposefully, on operation technique, more freely, makes operation safer.
As preferred version of the present invention, described notch is provided with outside and downward-sloping inclined-plane.At notch, outside and downward-sloping inclined-plane is set, makes the amplitude that scalpel can be downward-sloping larger, reduce the area of base plate, and the length that reduces the handle of a knife of scalpel, make integral body smaller and more exquisite.
Compared with prior art, tool has the following advantages in the present invention:
By base plate, support and elevating mechanism are set, base plate forms supporting surface and the reference plane of scalpel, and by the adjusting of elevating mechanism, adjust the size that base plate below blade exposes, thereby limited the degree of depth of feed, avoided the too shallow or too dark situation of feed, performed the operation more accurate, reduce patient's misery, more safe and reliable, in addition, pass through elevating mechanism, can adjust at any time the size that blade exposes, according to the degree of depth that need to adjust at any time feed of operation.
