Description
Technical field
This utility model relates to medical instruments field, is specifically related to the sleeve pipe perforator that a kind of disposable celiac mirror is used.
Background technology
The Minimally Invasive Surgery that with the peritoneoscope is representative developed rapidly in recent years, and its amount for surgical has surpassed traditional operation in developed country.Minor operation, little wound are the approval that the minimally-invasive treatment technology of characteristic progressively obtains numerous doctors.The sleeve pipe perforator is the indispensable apparatus that is used to set up operation path in the laparoscopic surgery, observes passage.The cutting tip of existing puncture needle has multiple shape: blunt taper shape, point taper shape, prismatic, four prismatics, six prismatics and blade or the like.Like the puncturing head of blunt shape, it little by little expands muscle fiber opens, and fiber is continuous, damage for a short time, and it is little that puncture casing takes out the back tissue defect, but the power of using when puncturing is maximum, is difficult to control troublesome poeration.And the puncturing head of blade, though it can just can directly cut muscle and fascia with less power, fiber is cut off; Tissue injury is big, and tissue defect is big but puncture casing takes out the back, and because of otch big; Place puncture casing and be difficult for fixing, deviate from easily, cause security incident.Though the puncturing head of many prismatics has the two advantage, the otch of its puncture equals the puncturing lever external diameter, and otch is big, and puncture casing be difficult for fixing, deviate from easily, be inconvenient to use.
The utility model content
The purpose of this utility model is, to above-mentioned deficiency, a kind of structural design advantages of simple, easy to operate is provided, and gathers the sleeve pipe perforator that blunt shape, many prismatics puncturing head advantage disposable celiac mirror are used.
For realizing above-mentioned purpose, the technical scheme that this utility model provided is:
The sleeve pipe perforator that a kind of disposable celiac mirror is used; It comprises a location puncture casing and one and the suitable polygonal pyramid puncture needle of this localised puncture sleeve pipe; This polygonal pyramid puncture needle is plugged in the said localised puncture sleeve pipe, and its head end slightly stretches out this localised puncture sleeve pipe.
Said polygonal pyramid puncture needle comprises that a puncturing lever and is arranged on the handle of this puncturing lever afterbody; The head end of this puncturing lever is provided with one and is conical puncturing head, is the center of circle on the taper seat of this puncturing head and is symmetrically distributed with a plurality of pyramids side and forms a pyramid end.
The circumradius of the bottom surface of said pyramid end is less than the radius of the bottom surface of puncturing head.
The ratio of the radius of the circumradius of the bottom surface of said pyramid end and the bottom surface of puncturing head is 0.4～0.8.
The lateral quantity of said pyramid is 3～6.
Said localised puncture sleeve pipe comprises cannula sheath, loam cake, sealing gasket, check-valves and two-port valve; The afterbody formation one of said cannula sheath and the suitable cavity of appearance profile of said check-valves; The stem of this cannula sheath extends axially along it, and said check-valves places in the cavity of this cannula sheath, and said sealing gasket is arranged on the opening of this cavity; Said loam cake is fastened on this cavity; And can be with said sealing gasket, check-valves location, said two-port valve is arranged on the said cannula sheath, and is connected with the cavity of this cannula sheath.
The lateral surface of the stem of said cannula sheath is provided with the nodular tapered protrusion, and the head end of this cannula sheath is tapered.
The beneficial effect of this utility model is: this utility model design is ingenious, rational in infrastructure, is provided with the polygonal pyramid puncture needle, when puncture; Utilize the pyramid end incised tissue on it earlier, the taper seat through puncturing head carries out reaming more then, damages little; Effectively improved the safety and the effectiveness of puncture operation, cannula sheath is provided with the nodular tapered protrusion, and stationarity is difficult for slippage well; Stop tradition and cause the phenomenon of security incident, and the head end of cannula sheath is tapered, the resistance in the time of can not only reducing to puncture because of easy slippage; Handled easily can also further reduce the otch damage is realized Wicresoft's effect.Link to each other with pneumoperitoneum apparatus through two-port valve, can gas be imported the abdominal cavity, the air pressure of abdominal part when keeping operation.In addition, overall structure is simple, is easy to realize that cost is low, and is disposable use, avoids cross infection, guarantees the safety of using.
Below in conjunction with accompanying drawing and embodiment, this utility model is further specified.

The specific embodiment
Referring to Fig. 1 to Fig. 6; The sleeve pipe perforator that a kind of disposable celiac mirror that present embodiment provides is used; It comprises a location puncture casing 1 and one and the suitable polygonal pyramid puncture needle 2 of this localised puncture sleeve pipe 1; This polygonal pyramid puncture needle 2 is plugged in the said localised puncture sleeve pipe 1, and its head end slightly stretches out this localised puncture sleeve pipe 1.
Said polygonal pyramid puncture needle 2 comprises that a puncturing lever 21 and is arranged on the handle 22 of these puncturing lever 21 afterbodys; The head end of this puncturing lever 21 is provided with one and is conical puncturing head 23, is the center of circle on the taper seat 24 of this puncturing head 23 and is symmetrically distributed with a plurality of pyramids side 25 and forms a pyramid end 26.
The circumradius r of the bottom surface of said pyramid end 26 is less than the radius R of the bottom surface of puncturing head 23.The ratio of the radius R of the circumradius r of the bottom surface of said pyramid end 26 and the bottom surface of puncturing head 23 is 0.4～0.8.
Said localised puncture sleeve pipe 1 comprises cannula sheath 11, loam cake 12, sealing gasket 13, check-valves 14 and two-port valve 15; The afterbody formation one of said cannula sheath 11 and the suitable cavity 16 of appearance profile of said check-valves 14; The stem of this cannula sheath 11 extends axially along it, and said check-valves 14 places in the cavity 16 of this cannula sheath 11, and said sealing gasket 13 is arranged on the opening of this cavity 16; Said loam cake 12 is fastened on this cavity 16; And can be with said sealing gasket 13, check-valves 14 location, said two-port valve 15 is arranged on the said cannula sheath 11, and is connected with the cavity 16 of this cannula sheath 11.
The lateral surface of the stem of said cannula sheath 11 is provided with nodular tapered protrusion 17, and the head end 18 of this cannula sheath 11 is tapered.
In the present embodiment, the quantity of said pyramid side 25 is 4, among other embodiment, and can be according to the required quantity of between 3～6, selecting corresponding pyramid side 25 of operation.
In when puncture, referring to Fig. 7, pyramid end 26 is thrust the human abdomen and is organized 3; Referring to Fig. 8, utilize the seamed edge incised tissue 3 of pyramid end 26, after puncturing head 23 gets into tissue 3 one segment distances; Referring to Fig. 9, utilize the 24 pairs of otch of taper seat on the puncturing head 23 to expand again, tapered because of the head end 18 of cannula sheath 11 then; Referring to Figure 10, utilize the conical surface also otch to be expanded, get into the abdominal cavity until perforator.Again perforator is advanced a segment distance in the abdominal cavity,, make the tapered protrusion 17 entering abdominal cavities of cannula sheath 11 referring to Figure 11.Under the combined effect of tapered protrusion 17 contractility that expansion forms with otch, thereby realize cannula sheath 11 is securely fixed on the stomach wall.Link to each other with pneumoperitoneum apparatus through two-port valve 15, can gas be imported the abdominal cavity, the air pressure of abdominal part when keeping operation.In addition, perforator adopts macromolecular material to process, and cross infection is avoided in disposable use, has guaranteed the safety of using.
Of this utility model the foregoing description, adopt structure same or similar and other perforator of obtaining, all in this utility model protection domain with it.
