Abstract
The invention discloses a minimally invasive scalpel manufacturing method which is based on a round slotting tool, a contracting chuck, an ejection rod and a minimally invasive scalpel. A plurality of first line through grooves and a plurality of second line through grooves are formed in the round slotting tool in the axial direction in parallel. The first line through grooves extend from one end face of the round slotting tool to the middle of the round slotting tool to form a plurality of first elastic blades. The second line through grooves extend from the other end face of the round scalpel to the middle of the round slotting tool to form a plurality of second elastic blades. The manufacturing method includes the following steps: step1 utilizing the contracting chuck to clamp the round slotting tool to form a deformed round slotting tool; step2 arranging the deformed round slotting tool in the step1 into a through hole of an outer aluminum pipe sleeve; step3 placing the ejection rod into the through hole of the outer aluminum pipe sleeve to push the ejection rod to drive the deformed round slotting tool to move. By means of the manufacturing method, small protruding points can be removed cleanly and smoothly, the round slotting tool have certain elastic force and can be in contact with the inner wall of an aluminum pipe at any time, and the small protruding points on the inner wall can be removed to the largest extent.
Description
Technical field
The present invention relates to medical instruments field, more particularly, to a kind of manufacture method of minimally-invasive scalpel.
Background technology
In prior art, coventional scalpel blade is roomy, and normal tissue damages greatly, is not suitable for doing Minimally Invasive Surgery.Minimally invasive
Operation is welcome by patient because wound is little, pain light, it is fast to recover.But the restriction due to equipment and condition, operation is to doctor
There is very high requirement.
Find that the outer aluminium pipe sleeve fraction defective of minimally-invasive scalpel remains high always through long-term processing, processing gained part one is big
Part cannot meet required precision.Its main cause occur in extrusion section bar charging bad, aluminium agent material inwall often occurs
0.05MM ~ 0.1MM small salient point, but this phenomenon cannot be improved in aluminium agent operation and cannot avoid salient point.Therefore need to be in rear road work
Sequence improves the yield that could improve product, meets the demand of client.
The outer aluminium pipe sleeve of this minimally-invasive scalpel is due to inwall bore very little（For 5.86MM）, also tolerance and inwall have different
Shape, and special-shaped very little（The a width of 0.7MM of abnormity）, its inwall small salient point cannot remove by commonsense method at all.Through repeatedly different
After method is attempted, how effectively efficiently the small salient point on the inwall having abnormity being removed, thus reaching required precision, improving
The yield of product, becomes the direction of those skilled in the art's effort.
Content of the invention
The present invention provides a kind of manufacture method of minimally-invasive scalpel, its clean glossily removal small salient point of this manufacture method,
Circular slotting tool has certain elastic strength can keep contacting with aluminum pipe inwall at any time and not injure inwall, can go to the full extent
Except the small salient point on inwall, effect is more preferable；Secondly this manufacture method, speed is quite quick, and this circular slotting tool length is not oversize,
The long rod of inwall only need to be put in gently one disclose and can complete to remove.
For reaching above-mentioned purpose, the technical solution used in the present invention is：A kind of manufacture method of minimally-invasive scalpel, this manufacture
Method is based on circular slotting tool, collet chuck, push rod and minimally-invasive scalpel；Described minimally-invasive scalpel includes：Outer aluminium pipe sleeve, inner tube set, knife
Piece, bar shaped handle of a knife and knife bar, this knife bar one end has groove, this bar shaped handle of a knife rectangular cross-section, and described bar shaped handle of a knife one end is solid
In the groove of described knife bar, described blade is welded on the side of the described bar shaped handle of a knife other end；
Described circle slotting tool axially parallel offers several First Line grooves, several the second line grooves along it, the
Integrated Service Digital Network groove extends in the middle part of circular slotting tool from circular slotting tool end face thus forming several the first elastic blades, and the second line leads to
Groove extends in the middle part of circular slotting tool from circular slotting tool other end thus forming several the second elastic blades, First Line groove,
Second line groove circumferentially partially overlaps, and circular slotting tool outer surface is provided with left and right raised line, the first elastic blade, the second elastic blade
Piece from inner surface to outer surface between there is an inclined-plane, this inclined-plane makes the first elastic blade, the second elastic blade in outer surface
End forms blade；
Described manufacture method comprises the following steps：
Step one, described circle slotting tool is clamped by collet chuck form circular slotting tool after deformation, so that circular slotting tool
Diameter reduces；
Step 2, slotting tool circular after step one deformation is put in the through hole of described outer aluminium pipe sleeve；
Step 3, push rod is put in the through hole of described outer aluminium pipe sleeve, promote push rod thus circular slotting tool after driving deformation
Mobile.
In technique scheme, further improved technical scheme is as follows：
1 preferably, the outer aluminium pipe sleeve of described first elastic blade, the outer surface of the outer aluminium pipe sleeve of the second elastic blade with tiltedly
The basil that outside face, aluminium pipe sleeve is formed is 60 ° ~ 75 °.
2 preferably, the outer aluminium pipe sleeve end of the outer aluminium pipe sleeve of several First Line grooves described, several the second line grooves
There is the outer aluminium pipe sleeve of bottom cutting edge.
Because technique scheme is used, the present invention compared with prior art has following advantages：
The manufacture method of minimally-invasive scalpel of the present invention, it totally glossily removes small salient point, and circular slotting tool has certain bullet
Property strength can keep contacting and not injuring inwall with aluminum pipe inwall at any time, the small salient point on inwall can be removed to the full extent,
Effect is more preferable；Secondly this manufacture method, speed is quite quick, and this circular slotting tool length is not oversize, only need to be put in inwall
With long rod gently one disclose can complete remove.
