Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, the operation path of specifically using in a kind of single-hole laparoscopic surgery.
Background technology
The more traditional porous laparoscopic surgery of single-hole laparoscopic surgery otch still less, more attractive in appearance, is one of developing direction of surgery Minimally Invasive Surgery.Operation path is the crucial apparatus of single-hole laparoscopic surgery.Single-hole laparoscopic surgery need be placed an operation path in unique otch, has a plurality of instrument hole on operation path, places the operating apparatuss such as a plurality of operating forcepies, operating scissors, and for preventing the instrument hole gas leakage on operation path, operation path should have air-leakage preventing device.Current existing single-hole laparoscopic surgery passage has the following disadvantages in operation: one, operation path is positioned at outside abdomen the fulcrum of apparatus, apparatus is with this spot wobble, and the operation path diameter that is positioned at stomach wall section is little, limited the hunting range of operating apparatus, make range of operation narrow and small; Two,, owing to lacking separation, the apparatus end of abdominal cavity inner segment easily crosses one another, and causes and interferes with each other; Three, at present common instrument hole majority needs support and the guiding of tubular structure, makes structural volume large, and easily collision is disturbed, and tubular structure increased the frictional resistance of apparatus, affect apparatus and passes in and out and operation technique; Four, a lot of operation paths need to insert extra leakproof trachea assembly, have strengthened volume, increase operating difficulties, affect operating apparatus and swing and come in and go out; Five, the operation path that adopts monolayer anti-gas-leak structure, obturation effect is poor, large to the viscosity resistance of operating apparatus, affects the fluency of operating theater instruments turnover; Six, some operation path can only be used in conjunction with expensive flimsy bendable laparoscopic instrument, and can not be for simple and reliable pre-bend hard laparoscopic instrument; Seven, operation path complex structure, fragile, and price is high; Eight, the design of some operation paths has difficulties in the exploitativeness of producing and applying.These deficiencies are to affect the unfavorable factor that single-hole laparoscopic is carried out.There is no at present to solve the operation path of above deficiency, this is to affect the main cause that single-hole laparoscopic is carried out simultaneously.
Summary of the invention
The technical issues that need to address of the present invention are, overcome that the operation path volume that background technology exists is large, operation path inner space is little, operating apparatus swing space is little, apparatus interferes with each other seriously, the narrow deficiency of the scope of application, provide a kind of simple in structure, processing ease, has enough apparatus swing spaces, can reduce apparatus collision and disturb, can, for the operation path of pre-bend hard single-port laparoscope instrument, reduce the difficulty of single-hole laparoscopic surgery.
A passage, comprises shell, instrument hole, air inlet pipe, exhaustor, it is characterized in that: shell consists of the hard sheath of tubular and the overseas cap that can cover on hard sheath.Hard sheath body shape comprises straight-tube shape, eel-like figure tubular, and internal orifice and collar extension all can be flat mouth or angle, and collar extension comprises the brim of a hat shape or bell mouth shape with ring ，Huan limit, limit common shape.In hard sheath main body, there are air inlet pipe and exhaustor.Hard sheath inside, with barrier, is divided into a plurality of subregions by hard sheath inner chamber.Barrier contains a plurality of branches, and branch shape comprises beam shape, tabular or analogous shape, and each branch crosses mutually or be adjacent to each other near the hard sheath cross section center of circle or the center of circle, and barrier shape includes but not limited to Y shape, cross, matrix pattern.Barrier can combine together by global formation with hard sheath inwall, also can to hard sheath, use barrier as assembling parts.Hard sheath and barrier have rigidity, and manufactured materials includes but not limited to polyethylene, thermoplastic polyurethane elastic plastic cement, metal.
Overseas cap is membrane structure, has high-tension and tensility, can arbitrarily change shape, and that common shape comprises is discoideus, cap shape, glove-like.On overseas cap, with a plurality of instrument hole, instrument hole and membrane structure merge, and instrument hole has one deck anti-gas-leak structure at least.Anti-gas-leak structure comprises and inserts the anti-gas-leak structure of apparatus and the anti-gas-leak structure of deployment instrument not from function, from textural crack type, valve type, ring-like, the flap valve type of comprising, from comprising in shape plate-like, UFO-like or taper.Overseas cap has high-tension and tensility, similar balloon and medical rubber glove, and manufactured materials includes but not limited to silica gel, rubber.Overseas cap can cover on collar extension or the internal orifice of hard sheath, and the fixed form of overseas cap and hard sheath comprises that silk thread cerclage, retainer ring fix.
Beneficial effect of the present invention is: adopt barrier to can be apparatus swing fulcrum is provided, be conducive to the conduction of operating theater instruments strength; Barrier does not have tubular structure, contacts with operating theater instruments bar point-like, the friction that can avoid tube-in-tube structure to cause apparatus bar parcel; Adopt barrier that a plurality of apparatuses are separated, avoid apparatus cross winding; Adopt barrier that limitation and restriction that laparoscopic instrument is subject to are reduced, compare the tube-in-tube structure that is enclosed within apparatus bar outside larger apparatus swing space can be provided, reduce apparatus collision and disturb, increase range of operation; Overseas cap is high range of extension membrane structure, can reduce restriction and restriction that apparatus is swung; By the air-leakage preventing device designs simplification on overseas cap, can reduce apparatus collision and disturb; On overseas cap, can avoid using tube-in-tube structure, what reduced that apparatus friction and tube-in-tube structure cause is crowded; There is no the restriction of tube-in-tube structure, therefore can use the various single-port laparoscope instruments that comprise pre-bend hard apparatus, applied range; Retain key structure, eliminate all structures that tie up the structure of inner space and increase apparatus interference simultaneously; Simplified structure, improves reliability, facilitates industrial implementation.The present invention possesses above advantage simultaneously, is the innovation to single-hole laparoscopic surgery passage.
