Abstract
The invention relates to medical apparatus, particularly relates to a working sheath for single-port laparoscope operations, and aims to solve the technical problems that the exiting working sheaths for single-port laparoscopes are large in size, operating instruments are difficult to swing, the instruments and the sheaths interfere each other, and the working sheaths are narrow in application range. The working sheath comprises a shell, instrument holes, an air inlet passage and an exhaust passage and is characterized in that the shell is provided with a plurality of seal sacs inside, and the shell is directly connected with the seal sacs which are provided with the instrument holes and seal valves. The working sheath has the advantages that volume of the working sheath is minimized, the structure of the anti-air-leakage devices is simplified, large instrument swing space is provided, instrument collision and interference are reduced, the diameter of the working sheath is reduced, and the working sheath is applicable various single-port laparoscopic instruments including pre-bending hard instruments.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, the working sheath pipe 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.The working sheath pipe is the crucial apparatus of single-hole laparoscopic surgery.Single-hole laparoscopic surgery need be placed a working sheath pipe in unique otch, and a plurality of instrument hole are arranged on the working sheath pipe, places the operating apparatuss such as a plurality of operating forcepies, operating scissors, and for preventing the instrument hole gas leakage on the working sheath pipe, the working sheath pipe should have air-leakage preventing device.Current existing single-hole laparoscopic working sheath pipe has the following disadvantages in operation: one, the fulcrum of instrument hole is outside abdomen, the fulcrum that apparatus is swung is also outside abdomen, and the working sheath pipe diameter that is positioned at stomach wall is little, limited the hunting range of operating apparatus, make range of operation narrow and small, and Intraabdominal apparatus end is easily crossed one another, cause and interfere with each other.Two, at present common air-leakage preventing device has double-decker, addition type structure and single layer structure, and wherein the depressed structure volume of double-layered anti-leakage is large, and easily collision is disturbed, and, because volume can only be placed on greatly externally, causes position of the fulcrum not good; Addition type anti-gas-leak structure need to be installed or add extra leakproof trachea on the working sheath pipe, has strengthened volume, affects operating apparatus and swings and come in and go out; Monolayer anti-gas-leak structure obturation effect is poor, large to the viscosity resistance of operating apparatus, the fluency of impact operation.Three, some working sheath pipe 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.Four, working sheath tubular construction complexity and placement difficulty.These deficiencies are to affect the unfavorable factor that single-hole laparoscopic is carried out.There is no at present to solve the working sheath pipe 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, the deficiency that the volume that overcomes the background technology existence is large, operating apparatus is difficult to swing, apparatus and the working sheath pipe interferes with each other, range of application is narrow, provide a kind of simple in structure, processing ease, enough swing spaces are arranged, can reduce the apparatus collision and disturb, can, for the working sheath pipe of pre-bend hard single-port laparoscope instrument, reduce the difficulty of single-hole laparoscopic surgery.
A kind of single-hole laparoscopic working sheath pipe, comprise shell, instrument hole, air intake duct, exhaust duct, it is characterized in that: several sealed bladders are arranged in shell, directly connect between shell and each sealed bladder, instrument hole and seal valve are arranged on sealed bladder; Each sealed bladder connected mode comprises and connecting side by side and the connection that misplaces; Between each sealed bladder cyst wall and between sealed bladder cyst wall and working sheath pipe shell, can merge mutually, amalgamation mode comprises that cyst wall shares and the cyst wall continuity; The sealed bladder shape comprises flat box-like, column, sacculus shape, irregular.Instrument hole is positioned at the sealed bladder upper wall, and shape includes but not limited to cross, circle.Seal valve is positioned at the sealed bladder lower wall, and structure includes but not limited to cover plate formula, two lobe formulas, fFour piece type.Air intake duct and exhaust duct pass the sealed bladder blister cavities or navigate within the sealed bladder cyst wall.The working sheath pipe shell is tubular, comprises straight-tube shape, the thin eel-like figure tubular in large middle part, two ends, and the shell cross sectional shape includes but not limited to circle, ellipse, rhombus.The outer mouth-shaped of working sheath pipe shell comprises flat mouth and angle, around collar extension, has ring ，Huan limit, limit shape to comprise the brim of a hat shape, horn-like, petal-shaped.In the working sheath pipe shell, mouth-shaped comprises flat mouth and angle.The working sheath pipe can wholely be manufactured molding or be formed by a plurality of assembling parts, and manufactured materials has elastic force, toughness, hardness, and material comprises plastic material and macromolecule polymer material.
Beneficial effect of the present invention is: the apparatus fulcrum of working sheath pipe is positioned at stomach wall, and larger apparatus swing space can be provided, and reduces the apparatus collision and disturbs; Adopt and directly connect and the shared mode of cyst wall, the working sheath pipe volume is minimized, by the air-leakage preventing device designs simplification, be conducive to reduce collision and disturb, reduce working sheath pipe diameter; Can be for comprising the various single-port laparoscope instruments of pre-bend hard apparatus, applied range.The present invention possesses above advantage simultaneously, is the innovation to single-port laparoscope instrument.
