Description
Technical field
This utility model relates to a kind of black box for perforator, and it is parts in perforator, belongs to medical apparatus and instruments, is mainly applicable in the laparoscopic surgery of human body.
Background technology
In prior art, human abdominal cavity operation widely uses perforator, is particularly used in Minimally Invasive Surgery field and laparoscopic surgery.Common perforator comprises thimble assembly, black box, needle assembly, because the syndeton design between each assembly is reasonable not, easily causes chronic leakage.
Chinese utility model patent application number 2013202959451 discloses one " perforator ", and it has also applied for invention simultaneously; This perforator comprises thimble assembly, black box, needle assembly and plug valve, elastic sealing element in black box is the taper shape of band one breach, and elastic sealing element has four, and the circumference cornerite of every part is 300 °-340 °, its overlapping area is little, and sealing property is good not; Meanwhile, black box is stuck in by the through hole 2-27 of the three-back-shaped snap close 2-23 of spring 2-24 pretension by dead bolt 2-11; When needing dismounting, pressed by two three-back-shaped snap close 2-23, dead bolt 2-11 breaks off relations from through hole 2-27, takes down black box.There is following shortcoming in this perforator: the structural design of the connection between thimble assembly and black box and three-back-shaped snap close 2-23 and connector thereof reasonable all not in actual use, carrying out easily producing extruding, collision, vibrations etc. in sterilizing, packaging, transportation, these uncontrollable factors very easily cause black box to come off, increased risk when making it use, this risk comprises bacterial index and exceeds standard, black box is damaged, etc.
Utility model content
Technical problem to be solved in the utility model to overcome in prior art existing above-mentioned deficiency, and provide a kind of structural design more rationally, sealing effectiveness is better for the black box of perforator.
The technical scheme in the invention for solving the above technical problem is: this black box being used for perforator comprises sealing lower cover, sealing ring, sealing upper cover, sealing lower cover, elastic sealing element, support member and sealing upper press cover, elastic sealing element is the taper shape of band one breach, it is characterized in that: the lower end of described sealing lower cover is also provided with and the rotary buckle sealing lower cover and be connected, this revotating card is buckled with four, they cover under being distributed on sealing respectively, and described elastic sealing element has identical five.Make the design of the syndeton between this utility model and thimble assembly more reasonable thus, sealing property is better, even and if in sterilizing, packaging, transportation, produce extruding, collision, vibrations, black box also can not be made to come off, design and safe and reliable.
The circumference cornerite of its every part of elastic sealing element described in the utility model is 225 °, the angle of its hole centre line of elastic sealing element is 18 °, the overlapping angle of its every two pieces of elastic sealing element is 153 °, and make the overlapping area of elastic sealing element large, sealing effectiveness is better.
This utility model compared with prior art, has the following advantages and effect: structural design is more reasonable, and the overlapping area of elastic sealing element is large, and sealing effectiveness is better; Meanwhile, after being connected with thimble assembly, black box can not be made in sterilizing, packaging, transportation to come off, design and safe and reliable.

Detailed description of the invention
See Fig. 1-Fig. 4, black box 1 of the present utility model comprises sealing lower cover 11, sealing ring 12, sealing upper cover 13, sealing lower cover 14, elastic sealing element 15, space bar 16, support member 17 and sealing upper press cover 18, and elastic sealing element 15 is the taper shape of band one breach; Wherein: sealing ring 12, sealing lower cover 14, elastic sealing element 15, space bar 16, support member 17 and sealing upper press cover 18 are all sealing between lower cover 11 and sealing upper cover 13, just define the structure of Fig. 3 after sealing lower cover 11 and sealing upper cover 13 are by their compressions and by ultrasonic bonding.
The lower end of sealing lower cover 11 of the present utility model is also provided with and the rotary buckle 111 sealing lower cover 11 and be connected, and this rotary buckle 111 matches with the thimble assembly of perforator in use; In the present embodiment, rotary buckle 111 has four, and they are distributed on sealing lower cover 11 respectively.
In the present embodiment, elastic sealing element 15 has identical five, and the circumference wrap angle sigma of every part is 225 °, and the overlapping angle of its every two pieces of elastic sealing element 15 is 153 °, and the angle β of its hole centre line of elastic sealing element 15 is 18 °.
During use, thimble assembly and the needle assembly of this utility model and perforator are connected, and form a perforator overall.Due to the perforator that matches with this utility model and thimble assembly SEPARATE APPLICATION patent all, so this utility model and the connection between them and principle just no longer describe in detail.
During operation, pierce through human body stomach wall by needle assembly, then extend there through other operating theater instruments and enter in human abdominal cavity and can carry out Wicresoft and laparoscopic surgery.
Specific embodiment described in this description, the title that its part is got can be different.All equivalences of doing according to structure, feature and the principle described in this utility model inventional idea or simple change, be included in the protection domain of this utility model patent.
