Abstract
The invention discloses a method for manufacturing a minimally invasive surgical knife. The method is on the basis of a circular slotting knife, a compressing mechanism, an ejector rod and the minimally invasive surgical knife; a plurality of first line through slots and a plurality of second line through slots are axially formed in parallel in the circular slotting knife; the first line through slots extend from one end surface of the circular slotting knife to the middle part to form a plurality of first elastic blades; the second line through slots extend from the other end surface of the circular slotting knife to the middle part to form a plurality of second elastic blades. The method comprises the following steps: 1, clamping the circular slotting knife with the compressing mechanism to form a reshaped circular slotting knife; 2, positioning the reshaped circular slotting knife obtained in step 1 into a through hole in an outer aluminum tube casing; 3, positioning the ejector rod into the through hole in the outer aluminum tube casing, and then pushing the ejector rod to drive the reshaped circular slotting knife to move. With the adoption of the manufacture method, small silent points can be cleanly and smoothly removed; the circular slotting knife can be kept in contact with the inner wall of an aluminum pipe without any damage to the inner wall because of a certain elasticity, and the small salient points on the inner wall can be removed to the maximum.
Description
Technical field
The present invention relates to medical instruments field, relate in particular to a kind of manufacturing process for scalpel.
Background technology
In prior art, general surgery cutter blade is roomy, and normal tissue damage is large, is not suitable for doing Minimally Invasive Surgery.Minimally Invasive Surgery is because wound is little, pain light, recover the fast welcome that is subject to patient.But due to the restriction of equipment and condition, operation has very high requirement to doctor.
Through long-term processing, find that the outer aluminium pipe sleeve fraction defective of Minimally Invasive Surgery cutter is always high, machining obtains part, and most cannot meet required precision.It is bad that its main cause appears at extrusion section bar charging, and aluminum agent material inwall often there will be 0.05MM ~ 0.1MM small salient point, yet this phenomenon cannot be improved and cannot avoid salient point in aluminum agent operation.Therefore need improve the yield that could improve product in later process, meet client's demand.
The outer aluminium pipe sleeve of this Minimally Invasive Surgery cutter, due to inwall bore very little (being 5.86MM), also has tolerance and inwall to have abnormity, and abnormity very little (abnormity is wide is 0.7MM), and commonsense method cannot be removed its inwall small salient point at all.After repeatedly distinct methods is attempted, how can will there is the small salient point on special-shaped inwall to remove effectively efficiently, thereby to reach required precision, improved the yield of product, become the direction that those skilled in the art make great efforts.
Summary of the invention
The invention provides a kind of manufacturing process for scalpel, it totally removes small salient point glossily this manufacturing process, circular slotting tool has certain elasticity strength to keep in touch and not injure inwall with aluminum pipe inwall at any time, can remove to the full extent the small salient point on inwall, better effects if; Secondly, this manufacturing process, speed is quite quick, and this active slotting tool length is not oversize, only need be put in inwall and one disclose and can complete removing gently with long rod.
For achieving the above object, the technical solution used in the present invention is: a kind of manufacturing process for scalpel, and this manufacture method is based on circular slotting tool, hold-down mechanism, push rod and Minimally Invasive Surgery cutter; Described Minimally Invasive Surgery cutter comprises: outer aluminium pipe sleeve, interior pipe box, blade, bar shaped handle of a knife and knife bar, this knife bar one end has groove, this bar shaped handle of a knife cross section is rectangle, described bar shaped handle of a knife one end is fixed in the groove of described knife bar, and described blade is welded on the side of the described bar shaped handle of a knife other end;
