Abstract
A novel multi-channel sheath comprises a multi-channel sealing part and an incision protection retractor (retraction sleeve). The multi-channel sealing part comprises channel valves, a shared channel, a positioning ring and ventilation pipelines. The incision protection retractor (retraction sleeve) solves the problems of protection and traction of an incision and connecting positioning of the multi-channel sealing part, namely the positioning ring of the sealing part is combined with an outer clamping ring of the protection retraction sleeve in an embedded mode. The positioning ring is arranged to be of a cap type, the upper end of the positioning ring and the shared channel can be bonded and fixedly connected or connected through a sliding rotation sealing ring, a convex-concave ring is arranged inside the cap to be combined with a concave-convex ring at the outer side of the outer clamping ring of the incision protection retractor (retraction sleeve) in an embedded mode, the convex-concave ring and the concave-convex ring are tightened, sealed and positioned, and the positioning ring can be fastened through a hoop. The multi-channel sealing part is resistant to instrument mutual interference, good in surgical operation sealing performance and high in adaptability to sizes of surgical instruments.
Description
Technical field:
This utility model belongs to medical operating articles for use, is specifically related to the multichannel sheath pipe that laparoscopic surgery uses.
Technical background:
In recent years, rapidly, laparoscopic surgery is universal gradually for Wicresoft's endoscope-assistant surgery development, and single-hole laparoscopic surgery is being taken seriously.The multichannel sheath pipe of indispensability in such operation (stamp card), existing multiple design and product both at home and abroad: as SilS port, Triport, Quadport, Oni-X port, these products main performance in use: whether operating apparatus sealing is good, whether convenient whether phase mutual interference of operating apparatus, change different size apparatus.When current multichannel sheath pipe operating apparatus, phase mutual interference becomes the key problem that impact use is promoted, and should improve the problem of structural design.Mutually disturb for getting rid of apparatus, have people to have in mind from sealing structural design, have people from using special bending operating theater instruments to set about, still undesirable so far, still in updating.
Summary of the invention:
The present utility model object is the deficiency that overcomes prior art, and the multichannel sheath pipe of innovation increases joins flexible fixing or rotatable common-use tunnel, solves the mutual interference problem of apparatus.
This utility model solves the technical scheme that its technology adopts: multichannel sheath pipe is made up of multichannel sealing and incision protection retractor (cover), and multichannel sealing is provided with flexible fixing or rotatable common-use tunnel; Be provided with and adopt the capping type connection locating ring of convex-concave ring and incision protection to retract the chimeric connection of cover.Multichannel sealing, containing channel valve, common-use tunnel, locating ring and vent line composition, is provided with flexible deformable common-use tunnel between valve passage and locating ring, and common-use tunnel is established sliding ring, makes between common-use tunnel and locating ring and has spinfunction.Incision protection retractor (cover) solves incision protection, retracts and be connected location with multichannel sealing; be sealing locating ring be entrenched in protection retract cover outer snap ring on; sealing locating ring retracts the outer snap ring of cover with incision protection and is connected with chimeric, forms multichannel sheath pipe.Sealing locating ring adopts the block of hooped type or sets up clip, guarantees positioning stablity.
Innovative technology measure of the present invention is: between channel valve and locating ring, increase and join one section of flexibility and fix or rotatable common-use tunnel, the feature of flexible common-use tunnel is: can flexible multidirectional deformation, cause operating theater instruments by multiple-way valve not only longitudinally push-and-pull move, also laterally (radially, circumferentially) twisting, positioning, amphi-position, can walk around apparatus stops mutually, expand operant activity scope, avoid phase mutual interference.Common-use tunnel and locating ring adopt monolithic molding or split production bonding connection, also can connect by slip rotating seal ring, and this common-use tunnel has not only deformable but also rotatable function.In the time that multiple operating theater instruments are passed through common-use tunnel, not only can be out of shape and avoid phase mutual interference by common-use tunnel, more can rotate and further avoid interference generation by common-use tunnel, more optimize apparatus anti-interference function.The main supporting large scale product of rotation common-use tunnel, the main supporting small-size product of common-use tunnel without spin.
Innovative technology measure of the present invention is: locating ring is established capping type; upper end can with the common-use tunnel interconnection system that is adhesively fixed; or connect by slip rotating seal ring; the concavo-convex ring of establishing the outer snap ring of convex-concave ring and incision protection retractor (cover) outside in block is chimeric; captive closure location, can adopt clip to strengthen for reinforcing locating ring.Incision protection retractor (cover) is provided with the flexible duct that can uprise; interior snap ring has strain and elastic recovery function; can embed otch inwall; outer snap ring needs upset; its section morphology should be S-shaped or Crossed Circle can radially overturn with hands, and can be connected with the locating ring of sealing is chimeric.
This utility model has following beneficial effect
1. multichannel sheath pipe increases and joins one section of flexibility and fix or rotatable common-use tunnel, solves the mutual interference of multiple operating theater instruments operation phase.
2. locating ring adopts convex-concave ring cowling cap hooped type connected mode, can fast and reliable ground and incision protection retract the chimeric connection of cover, formation multichannel sheath pipe.
Brief description of the drawings:
Fig. 1. multichannel sheath pipe side-looking structural representation.(Fig. 1 a without spin common-use tunnel and hands helps the chimeric connection diagram of formula (S shape) incision protection retractor, Fig. 1 b rotation common-use tunnel and helps the chimeric connection diagram of formula (Crossed Circle) incision protection retractor with hands)
Fig. 2. multichannel sheath seal of tube portion side-looking structural representation (Fig. 2 a without spin common-use tunnel, Fig. 2 b rotation common-use tunnel establishes slip rotating seal ring with locating ring and is connected)
Detailed description of the invention:
Embodiment mono-
As this utility model multichannel sheath seal of tube portion of Fig. 1 a, Fig. 2 a establishes channel valve 1, common-use tunnel 2, locating ring 3 and vent line 4 thereof, convex-concave ring cowling hat type locating ring 3 helps formula incision protection to retract the chimeric location of the outer snap ring 5-1 of cover (section S shape) with hands.
Sealing and incision protection retract cover with the chimeric formation multichannel of locating ring sheath pipe; interior snap ring 5-2 embeds otch inwall; channel valve, common-use tunnel can and keep sealing into and out of, operation apparatus, and common-use tunnel distortion can be got rid of apparatus and mutually disturbs, and improves its sealing and adaptability.
Embodiment bis-
As this utility model multichannel sheath seal of tube portion of Fig. 1 b, Fig. 2 b establishes channel valve 1, common-use tunnel 2 (containing establishing sliding ring 2-1, lubrication and seal circle 2-2 in common-use tunnel bottom), locating ring 3 (containing sealing subring 3-1, clip 3-2) and vent line 4 thereof, convex-concave ring cowling hat type locating ring 3 helps formula incision protection to retract the chimeric location of outer snap ring 5-1 of cover 5 (cross section Crossed Circles) with hands.
