Abstract
The utility model discloses a slotting tool used for processing a medical device. The cross section of a slotting tool body is circular; a plurality of first line through grooves and a plurality of second line through grooves are axially parallelly arranged in the slotting tool body; the first line through grooves extend from one end face of the slotting tool body to the middle part of the slotting tool body, so a plurality of first elastic blades are formed; the second line through grooves extend from the other end face of the slotting tool body to the middle part of the slotting tool body, so a plurality of elastic blades are formed; the first line through grooves and the second line through grooves partially coincide in the circumferential direction; left and right protruding strips are arranged on the outer surface of the slotting tool body; a slope is formed between the inner surface and the outer surface of each of the first elastic blades; a slope is formed between the inner surface and the outer surface of each of the second elastic blades; and the slopes allow the first elastic blades and the second elastic blades to form cutter edges on the tail end of the outer surface. The slotting tool is capable of removing small projecting points smoothly and cleanly; with certain elastic force, the slotting tool can contact with but not damage the inner wall of an aluminum pipe; and the small projecting points on the inner wall can be removed to the large degree.
Description
Technical field
The utility model relates to medical instruments field, relates in particular to a kind of slotting tool for machining medical utensil.
Background technology
In prior art, 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, but its technology difficulty is very large.
Find that through long-term processing 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 aluminium agent material inwall often there will be 0.05MM ~ 0.1MM small salient point, but this phenomenon cannot be improved and cannot avoid salient point in aluminium 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, improve the yield of product, become the direction that those skilled in the art make great efforts.
Summary of the invention
The utility model provides a kind of slotting tool for machining medical utensil, this slotting tool can totally be removed small salient point glossily, slotting tool has certain elasticity strength to keep in touch with aluminum pipe inwall at any time and does not injure inwall, can remove to the full extent the small salient point on inwall, better effects if, only need be put in the long rod of inwall and one disclose and can complete removing gently.
For achieving the above object, the technical solution adopted in the utility model is: a kind of slotting tool for machining medical utensil, described slotting tool cross section for circular and along its axially parallel offer several First Line grooves, several the second line grooves, thereby First Line groove extends to slotting tool middle part from slotting tool one end face and forms several the first elastic blades, thereby the second line groove extends to slotting tool from slotting tool other end, middle part forms several the second elastic blades, First Line groove, the second line groove is along circumferentially partially overlapping, slotting tool outer surface is provided with a left side, right raised line, the first elastic blade, the second elastic blade is from inner surface to having an inclined-plane between outer surface, this inclined-plane makes the first elastic blade, the second elastic blade forms blade at outer surface end.
In technique scheme, further improved technical scheme is as follows:
1, as preferred, the basil that the outer surface of described the first elastic blade, the second elastic blade and inclined-plane form is 60 ° ~ 75 °.
2,, as preferred, described several First Line grooves, several the second line groove ends have bottom blade.
3, as preferred, the number of described First Line groove is 4, and the number of described the second line groove is 4.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is for the slotting tool of machining medical utensil, and it can totally remove small salient point glossily, and 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 slotting tool speed is quite quick, and this active slotting tool length is not oversize, only need be put in the long rod of inwall and one disclose and can complete removing gently.
Brief description of the drawings
Accompanying drawing 1 is for the utility model is for the slotting tool structural representation of machining medical utensil.
In above accompanying drawing: 1, First Line groove; 2, the second line groove; 3, the first elastic blade; 4, the second elastic blade; 5, left raised line; 6, right raised line; 7, inclined-plane; 8, blade; 9, bottom blade.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: a kind of slotting tool for machining medical utensil, described slotting tool cross section for circular and along its axially parallel offer several First Line grooves 1, several the second line grooves 2, thereby First Line groove 1 extends to slotting tool middle part from slotting tool one end face and forms several the first elastic blades 3, thereby the second line groove 2 extends to slotting tool from slotting tool other end, middle part forms several the second elastic blades 4, First Line groove 1, the second line groove 2 is along circumferentially partially overlapping, slotting tool outer surface is provided with a left side, right raised line 5, 6, the first elastic blade 3, the second elastic blade 4 is from inner surface to having an inclined-plane 7 between outer surface, this inclined-plane 7 makes the first elastic blade 3, the second elastic blade 4 forms blade 8 at outer surface end.
The outer surface of above-mentioned the first elastic blade 3, the second elastic blade 4 and the basil that inclined-plane 7 forms are 60 ° ~ 75 °.
