Abstract
The utility model relates to a skin tissue expander controllable by an injecting valve arranged outsides. A combined connecting pipe (3) is arranged at the center and through an expanding gasbag (1), and inside of the connecting pipe is arranged with a draught tube (b) and an inlet hose (a). The draught tube is provided with two water conducting inlets (7), a water-conducting outer hole (5) and a sealed plunger of the water conducting outer hole (6). One end of the inlet opening hose (2) is opened in the expanding gasbag, and the end is controlled by an injecting valve (4). The employment of a water conducting device simplifies the procedures of operations and shortens the time and curing term, besides the utility model also has the advantages of little injury and pain and few postoperative complications, simultaneously, the extensibility, stability and directivity of the expanding gasbag are improved.
Description
This utility model relates to the plastic surgery of hospital medical apparatus and instruments, a kind of controllability introduction valve door externally positioned type skin tissue expander.
The dilator that the method for utilization operation is made silica gel matter is imbedded in the skin soft tissue, regularly carrying out normal saline injects, make its bulge and impel the local skin soft tissue to be subjected to drawing-off expansion gradually, thereby for the plastic surgery provides skin soft tissue, become the treatment means that the plastic surgery uses always, this dilator is also referred to as internally-arranged type soft tissue expander, normally is connected with a conduit by an expansion capsule.In clinical practice, though it provides certain help for being on the waiting list skin soft tissue, have what time to be difficult for overcoming, the first, if sewing needle easily punctures the expansion capsule careless manipulation, causes the postoperative expansion capsule is flat to contract, and does not have the swollen effect of rising; The second, because the heeling-in cycle is longer, easily cause postoperative hydrops inadequate drainage, cause skin infection then, cause operative failure; The 3rd, owing to be the internally-arranged type heeling-in, increased certain difficulty for the operation sequence of regularly injecting normal saline; The 4th, because the expansion capsule is unordered placement, can make the skin bulge though inject normal saline in skin soft tissue, it does not have directivity and steadiness.
The purpose of this utility model is a kind of controllability introduction valve door externally positioned type skin tissue expander of design, makes it to be convenient to control water injection rate, is convenient to make the interior hydrops of skin to external drainage, strengthens extensibility, directivity and the steadiness of expansion capsule.
For implementing the foregoing invention purpose, this utility model adopts following technical scheme:
Described controllability introduction valve door externally positioned type skin tissue expander, it is the connecting duct of the conduit in the dilator having been made set composite, make it between two parties through the expansion capsule, and two ends extend the expansion capsule outside, the connecting duct of set composite is combined into one by water injection pipe and drainage tube; Water injection pipe in the connecting duct of set composite stretches in the middle of the expansion capsule, and a capsule inner opening is arranged, and is communicated with the injection valve outside the expansion capsule; Drainage tube in the connecting duct of set composite is outside expansion capsule and extension expansion capsule, and an end forms cecum, and the other end is provided with outer hole of drain and the outer hole of drain closed piston, offers two draining holes on the drainage tube at two ends outside close expansion capsule.
Described controllability introduction valve door externally positioned type skin tissue expander, its injection valve is made up of spool, elasticity adapter sleeve, rubbery loop, and wherein spool is communicated with water injection pipe in the connecting duct.
Owing to adopted aforesaid technical scheme, made it have following superiority:
Controllability introduction valve door externally positioned type skin tissue expander of the present utility model, owing to be that injection valve and the outer hole of drain are placed outside the skin soft tissue, strengthened the controllability of manual operation, simultaneously because connecting duct in the expansion capsule, has also strengthened extensibility, steadiness and the directivity of expansion capsule; The spool that has the crack in the injection valve is fastening by elasticity adapter sleeve and rubbery loop, has guaranteed air tight, the leakage of expansion capsule, also is convenient to external fixing.Characteristics such as simultaneously, also simplified operative procedure, shortened the operating time and the course of treatment, it is little to have wound, and post-operative complication is few.
Describe specific embodiment with reference to the accompanying drawings in detail:
Fig. 1 is the overall structure sketch map of controllability introduction valve door externally positioned type skin tissue expander; Fig. 2 is the radial section figure of connecting duct; Fig. 3 is the axial section of injection valve.
Among Fig. 1: 1-expansion capsule, 2-connecting duct capsule inner opening, 3-connecting duct
The outer hole of the outer hole 6-drain of 4-injection valve, 5-connecting duct drain closed piston
7-draining hole
Among Fig. 2: a-water injection pipe b-draining hole
Among Fig. 3: c-spool d-elasticity adapter sleeve e-rubbery loop
Dilator of the present utility model, be that connecting duct (3) by a set composite runs through expansion capsule (1) between two parties, outwards stretch about 1 centimetre and form cecum, and be provided with two draining holes (7) near expansion capsule two ends, be provided with two tubes in the connecting duct, a water injection pipe (a) connects injection valve (4) and leads to intermediate formation one opening (2) in the expansion capsule, so that quantitatively inject normal saline, another root drainage tube (b) is through whole expansion capsule, except that being provided with two draining holes, branch out hole outside the drain (5) at a end, block up it by closed piston (6) when not needing drain near the injection valve.Spool in the injection valve is communicated with formation water filling path with water injection pipe, its outer ring is fastening by an elasticity adapter sleeve, and outmost turns is a rubbery loop, has so just formed when filling with normal saline in the expansion capsule, to guarantee this port no leakage, gas leakage, help simultaneously fixing.
In the plastic surgery operations practice, expansion capsule and two draining holes are to be embedded in simultaneously in the skin soft tissue, how much that injects normal saline in the expansion capsule has certain proportionate relationship with the size of being on the waiting list the epidermis area, the drainage of draining hole is reliable, do not need to place again the pressure dressing of another drainage tube and postoperative during operation, when not using by piston closes, in case and generation cavity in hydrops, can in time discharge through drainage tube.
Claims (2)
1, a kind of controllability introduction valve door externally positioned type skin tissue expander, form by expansion capsule and connecting duct, it is characterized in that: between two parties through expansion capsule (1), and extend outside the expansion capsule by two ends by the connecting duct of set composite for the connecting duct of this dilator (3); The connecting duct of set composite (3) is combined into one by water injection pipe (a) and drainage tube (b); Water injection pipe in the connecting duct of set composite stretches in the middle of the expansion capsule, and a capsule inner opening (2) is arranged, and is communicated with Water filling valve (4) outside the expansion capsule; Drainage tube in the connecting duct of set composite is through expanding capsule and extending outside the expansion capsule, one end forms cecum, the other end is provided with outer hole (5) of drain and the outer hole closed piston (6) of drain, offers two draining holes (7) on the drainage tube at two ends outside near the expansion capsule.
