Description
Technical field
This utility model relates to perforator, the multiaxis that is specifically related to deep tissue in a kind of body to perforator.
Background technology
Perforator be percutaneous get involved the back to in-vivo tissue (as the deep tissues of breast, Intraabdominal internal organs and brain, nerve, blood vessel and body of gland etc.) position, expand, implantation, radio frequency, melt, injection, anesthesia, biopsy is extracted and minimally-invasive treatment operating equipment such as operation.The structure of perforators such as injection, biopsy extraction, anesthesia and operation commonly used comprises puncture casing and puncture needle at present, puncture casing commonly used is generally lumen diameter and is about 0.6～6mm, length is about the hollow pipe of 20～300mm, make by harmless materials such as rustless steel, puncture needle commonly used is generally the about 0.1～6mm of external diameter, the hollow elasticity needle body of the about 50～350mm of length is made by highly elastic materials such as harmless rustless steel, carbon fiber and fiber optics.Earlier the puncture casing percutaneous being got involved in during puncture needs the location, nearly tissue place of handling, then puncture needle is stretched out by tube head from the tube chamber that the pipe tail inserts puncture casing, to the tissue that need are handled inject, biopsy extraction, anesthesia and operation etc.Puncture needle commonly used at present is the craspedodrome needle body, needle end is provided with angular cut, the tube head of puncture casing is a round mouth, tube chamber is for beginning to keep straight on from the pipe tail from managing craspedodrome single tube or the tube chamber that tail to tube head all is craspedodrome, it is the arc single tube that is convexly curved at nearly tube head place, for keeping straight on axially, be that diagonal is axial when the puncture needle of arc single tube stretches out when the puncture needle of craspedodrome single tube stretches out, above-mentioned two kinds of puncture casing all be puncture needle when stretching out craspedodrome or the single shaft of diagonal to perforator.Single shaft to perforator make puncture needle can only single shaft to few zone of near axis obtain puncture and implement treatment, the outer most of zones of axis then become the blind area, can only make simple minimally-invasive treatment so once get involved to keep somewhere; To the treatment of larger area pathological tissues, just need repeatedly to get involved to keep somewhere just to finish treatments such as injection, biopsy extraction, anesthesia and operation, treatment time is increased, get involved tissue damaged's enlarged areas, the treatment risk improves, and the treatment difficulty increases, and patient's misery index raises.For each area of organizing of keeping somewhere treatments such as increasing injection, biopsy extraction, anesthesia and operation of getting involved, publication number is CN2378008, open day is 2000.05.17, name is called a kind of utility model of dual pathways puncture anesthetic needle, then disclose by straight tube passage and curved channel form dual pathways pipeline, once get involved to keep somewhere and to insert two nook closing members simultaneously, a nook closing member axially stretches out for keeping straight on, another axially stretches out for diagonal, institute thinks multiaxis to perforator, can finish dura mater anesthesia and lumbar anesthesia; Though this utility model can reach multiaxis to the puncture for treating purpose, once get involved the corresponding increase of anesthesia area of keeping somewhere, but the pin chamber of needle body is two, the volume of needle body is with regard to corresponding increase, it is corresponding just bigger that back tissue damaged area is kept somewhere in each intervention, do not reach the requirement of minimally-invasive treatment, increased patient's wound face and misery index.
Summary of the invention
The multiaxis that technical problem to be solved in the utility model provides deep tissue in a kind of body to perforator, this lancet device is once got involved and is just kept somewhere and can treat on axial at least two, the treatment area is corresponding bigger, and gets involved the less advantage of tissue damaged's area of keeping somewhere.
This utility model solves the problems of the technologies described above the technical scheme that is adopted: in a kind of body the multiaxis of deep tissue to perforator, the puncture casing that comprises puncture needle and craspedodrome, described puncture needle comprises backshank end and needle end, described needle end is provided with angular cut, the length of described puncture needle is 50～350mm, external diameter is 0.1～5.8mm, described puncture casing comprises tube head, pipe tail and tube chamber, described puncture casing length is 20～300mm, described lumen diameter is 0.6～6mm, be provided with the side opening that diameter is 0.6～8mm from tube head 3～10mm place on the described puncture casing, the nearly tube head edge of described side opening is provided with elastic tongue piece, the length of described elastic tongue piece is 0.6～6mm, the positioning end of described elastic tongue piece is fixedlyed connected with the tube wall of described puncture casing, the movable end of described elastic tongue piece stretches in the described tube chamber to described pipe tail direction is oblique from described side opening, the movable end of described elastic tongue piece does not pass the axis of described tube chamber, the angle of the extended line of described elastic tongue piece and the axis of described tube chamber is 10～45 degree, described needle end is made as bending section, the length of described bending section is 5～50mm, the radius of curvature of described bending section is 1～10 times of described bending section length, and the angle of the tangent plane of described angular cut and the outer tangent line of described bending section is 5～60 degree.
