Description

A kind of scalpel with position limitation protection
Technical field
The present invention relates to a kind of scalpel, particularly relate to a kind of scalpel with position limitation protection.
Background technology
The surgical instrument that scalpel is surgery, internal medicine is commonly used, any operation all must use scalpel, and visible scalpel is the essential condition of operation, quite important.
Scalpel is more single due to function, does not structurally all have what 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, cuts with blade periphery of diseased region with it the patient.The tissue of excision disease sites, or cut some tissue samples and carry out chemically examining, analyzing, finally to reach the object making Rehabilitation, this is also that one the most effectively, is the most directly cured the disease mode.
Current scalpel does not control the position limiting structure of the blade depth, and the depth of doctor's cutter relies on experience and the maneuver of doctor, and the depth is difficult to accurate control, often occurs that blade crosses shallow or excessively dark situation.During operation, blade is excessively shallow, then do not reach cutting object or cutting effect, need feed again again to cut, increase unnecessary misery to patient; And blade is excessively dark, then can damage patient, increase unnecessary misery to patient equally.Therefore, also there is defect safe and reliable not in current scalpel, and this is also the technical barrier all the time expecting to solve.
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 adopted is as follows:
Have a scalpel for position limitation protection, comprise handle of a knife and blade, 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 installing is 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 below base plate 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.
Insert generally comprises the knife back and blade.
When performing the operation, first according to the needs of operation depth of cut, first regulate blade by elevating mechanism and expose size below base plate, then base plate is placed into patient's operative site with it, while feed, drag base plate slide on operative site, under the restriction of base plate, the degree of depth of feed is the size that blade exposes below base plate.By arranging base plate, support and elevating mechanism, base plate forms the supporting surface of scalpel and reference plane, and by the adjustment of elevating mechanism, the size that below adjustment base plate, blade exposes, thus limit the degree of depth of feed, avoid the situation that feed is too shallow or too dark, perform the operation more accurate, reduce the misery of patient, more safe and reliable, in addition, pass through elevating mechanism, the size that blade exposes can be adjusted at any time, need according to what perform the operation the degree of depth adjusting feed at any time.
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 matched with screw rod, and the lower end inside wall 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 is 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 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 engaging of screw thread and screw rod, making screw rod and sleeve relative motion in the axial direction, is namely make screw rod do elevating movement in the vertical direction, thus drive the middle and lower part lifting of handle of a knife, namely have adjusted the gradient of handle of a knife, thus have adjusted blade and expose size below base plate, have 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, directly read the degree of depth of feed from station location marker line, 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 being rotatable is 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 hinged.By shake rocking bar, make pinion rotation, gear driven tooth bar does oscilaltion campaign in tooth bar fairlead, thus drive the middle and lower part lifting of handle of a knife, namely have adjusted the gradient of handle of a knife, thus have adjusted blade and expose size below base plate, have 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, directly read the degree of depth of feed from station location marker line, 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.Arrange curve slope by the edge at base plate, reduce resistance, base plate movement on a 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 and positions blade holder, more stable, can not shake, make it possible to feed reposefully, make operation safer on operation technique more freely.
As preferred version of the present invention, described notch is provided with outside and downward-sloping inclined-plane.Outside and downward-sloping inclined-plane is set at notch, makes the amplitude that scalpel can be downward-sloping larger, reduce the area of base plate, and reduce the length of handle of a knife of scalpel, make entirety smaller and more exquisite.
Compared with prior art, tool has the following advantages in the present invention:
By arranging base plate, support and elevating mechanism, base plate forms the supporting surface of scalpel and reference plane, and by the adjustment of elevating mechanism, the size that below adjustment base plate, blade exposes, thus limit the degree of depth of feed, avoid the situation that feed is too shallow or too dark, perform the operation more accurate, reduce the misery of patient, more safe and reliable, in addition, pass through elevating mechanism, the size that blade exposes can be adjusted at any time, need according to what perform the operation the degree of depth adjusting feed at any time.
