Detailed description of the invention
Below in conjunction with the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1
Refer to Fig. 1-Fig. 3, in the embodiment of the present invention, a kind of laparoscopic surgery puncture casing preventing abdominal visceral browser penetration damage, comprise veress needle, cutting piercing blade 1, puncture tube core 3, puncture trocar sheath 5, integral type grips ear 7 and die base 10, be followed successively by veress needle from the inside to the outside, piercing blade 1, puncture tube core 3, puncture trocar sheath 5, veress needle comprises pneumoperitoneum piercing needle 11, puncture handle 12, gas interface valve 8 and gas interface 9, pneumoperitoneum piercing needle 11 connects puncture handle 12 by spring, puncture handle 12 is provided with gas interface valve 8 and connects gas interface 9, and gas interface valve 8 and pneumoperitoneum piercing needle 11 are vertically arranged, gas interface 9 and pneumoperitoneum piercing needle 11 are vertically arranged.
Puncture tube core 3 adopts cylindrical; and the top of puncture tube core 3 is provided with hemispherical die head 2, cutting piercing blade 1 is in hemispherical die head 2, and hemispherical die head 2 can stretch; for the protection of cutting piercing blade 1, the other end of puncture tube core 3 connects die base 10 by spring.Also be provided with integral type between puncture tube core 3 and die base 10 and grip ear 7, integral type grips on ear 7 and connects gas interface 9 by gas interface valve 8.
Puncture trocar sheath 5 is provided with puncture inclined-plane 4 in one end that distance piercing blade 1 is nearer, and puncture inclined-plane 4 can reduce tissue injury, and puncture trocar sheath 5 is also provided with trocar sheath antiskid thread 6.
Be the hemispherical die head 2 that can stretch by puncture tube core 3 tip designs in the present invention, piercing blade 1 is hidden in hemispherical die head 2 internal fixtion on die base 10, when puncture meets obstructions, the spring pressurized at hemispherical die head 2 rear, hemispherical die head 2 is caused to retreat, thus exposing piercing blade 1 under covering, piercing blade 1, owing to being subject to external force when puncturing, thrusts stomach wall smoothly.After piercing blade 1 enters peritoneum, the resistance in piercing blade 1 front disappears, the spring at hemispherical die head 2 rear recovers the original length, hemispherical die head 2 is driven to reset, again piercing blade 1 is stashed, tube core 3 blade after entering abdominal cavity is hidden in hemispherical die head 2 owing to puncturing, the hemispherical die head 2 of passivity can not cause the damage of internal organs, so play the effect preventing visceral organ injury.Puncture casing sealing deficiency in the past causes leaking in operation leakage, wastes energy.
The present invention has carried out 3 layers of optimal design to the sealing of puncture casing, ensure that sealing to the full extent.To the use of obese patient, take the trocar sheath antiskid thread 6 of lengthening, and the puncture trocar sheath 5 lengthened, length can reach 13cm, reduces the risk of puncture trocar sheath 5 slippage.
The present invention is made up of the tube core 3 that punctures, die base 10, puncture trocar sheath 5, gas interface 9 etc.Puncture tube core 3 is generally tip design, is connected with die base 10, is inserted in by puncture tube core 3 in puncture trocar sheath 5, thrusts abdominal cavity under external force during puncture.Gas interface 9 is positioned on puncture trocar sheath 5, is provided with sealing device in puncture trocar sheath 5.After puncture trocar sheath 5 entirety enters abdominal cavity, take out puncture tube core 3, the trocar sheath 5 that now punctures just becomes the operating walk way of laparoscopic surgery.
The advantage that the present invention has is:
1, efficient sealing, reduces the leakage of gas and the leakage of flushing liquid in operation, change in the past laparoscopic surgery time operating-table on damp state.Because apparatus was reused and repeated disinfection in the past, the silica gel sealing of puncture casing and service aisle lowers along with the increase of access times, in order to keep carbon dioxide gas insufflation pressure in operation, needing to supplement compared with the carbon dioxide of large discharge, adding the consumption of gas.
2, the protectors such as puncture trocar sheath 5 are provided with at veress needle head; afterbody has a Compress Spring, and make puncture trocar sheath 5 free-extension, during operation, pneumoperitoneum piercing needle 11 is after penetrating stomach wall; needle tip retracts is in guard mode, avoids pneumoperitoneum piercing needle 11 to damage internal organs.
3, can effectively keep air-tightness in puncture casing, need only add with transducer according to demand to the operating theater instruments of different-diameter, easy to use.
4, human engineering configuration design, is easy to operator and grips.Puncture tube core 3 piercing blade 1 when puncturing is conducive to fly-cutting tissue, and penetration Resistance is little, and the doctress that when being convenient to gynecilogical operation, strength is less uses, and guarantees to perform the operation and carries out smoothly.
5, piercing blade 1 design protection, after puncture tube core 3 is through stomach wall, after puncture tube core 3 front resistance is disappeared, piercing blade 1 is retracted in circular hemispherical die head 2 at once, greatly improves puncture safety.
6, trocar sheath antiskid thread 6 designs, and is convenient to obese patient and uses, operation middle sleeve is not easily shifted along with the turnover of operating apparatus, even deviates from.
7, gas interface 9 level design of veress needle, relative to product was at top vertical air inlet in the past, operator operation is convenient in the present invention, and reduces the compressing of pneumoperitoneum pipeline to service aisle.The present invention makes puncture casing hommization more.
8, the piercing blade 1 of puncture tube core 3 is spacing by alignment pin with puncture trocar sheath 5, reduces the movement in piercing blade 1 direction in piercing process, and tissue wound is damaged in minimizing.
9, global design uses material to reduce, and is conducive to energy-conserving and environment-protective.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or basic feature, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
