Abstract

The utility model relates to a soft tissue dilator for medical application, which is made of silica-gel for medical application, wherein, an injection kettle, a conduit pipe, and a dilatation bursa are provided. The conduit pipe is connected with the injection kettle and the dilatation bursa; the inner wall of the connection of the dilatation bursa and the conduit pipe is provided with a barrier chip; besides a 1-2 mm crevice which is reserved open into the outside of the conduit pipe between the barrier chip and the inner wall of the dilatation bursa, the rest part is closely attached entirely. While in use, the utility model, which is buried subcutaneously, injects physiological saline into the dilatation bursa through the injection kettle and the conduit pipe. The water pressure in the dilatation bursa seals off the pipe opening by oppressing the barrier chip, so that the brine in the bursa can not reflux, and the brine can inject into the bursa under the pressure of the injection syringe.

Description

Soft tissue dilato

This utility model relates to a kind of medical soft tissue expander, belongs to a kind of plastic surgery's articles for use.

In the plastic surgery, when on the skin because of burn or be subjected to wound to leave cicatrix to influence when attractive in appearance, be to adopt skin grafting to make it to restore to the original state in the past, but after the skin-grafting, skin color often changes, and leaves over cicatrix for Pi Chuyao, and now the employing having a side of cicatrix more, implant soft tissue expander, stage by stage to wherein injecting normal saline, make cicatrix near skin expand gradually, treat that puffiness of skin is long after to a certain degree, with scar excision, dilator is taken out,, repair cicatrix the soft tissue and the cutaneous metastatic of expansion upheaval, reach cosmetic result, and avoid at its place's bark fetching of health.

But existing soft tissue expander, because wanting repeated multiple times expands normal saline in the capsule by injection kettle, conduit, injection with syringe, saline refluxes, overflows in the expansion capsule in order to prevent to inject, the necessary Precision Machining of injection kettle, strengthen the manufacturing cost of soft tissue expander, and syringe must be used than the fine needle head, prolongs medical personnel's per injection time, wastes time and energy.

The purpose of this utility model is that a kind of improved medical soft tissue expander will be provided, and it can make injection expansion CF body can not reflux, thereby reduces medical personnel's water injection time, and is time saving and energy saving.

The purpose of this utility model is achieved in that this soft tissue expander made by medical silica-gel, comprising injection kettle, conduit and expansion capsule, conduit is ined succession and is injected kettle and expansion capsule, on the inwall of expansion capsule and conduit joint, be provided with catch, between this catch and expansion capsule inner wall, lead to the conduit except that leaving the 1-2mm slit, all the other are all closely connected.During use, this utility model is imbedded subcutaneous, by injection kettle, conduit, injected normal saline in the expansion capsule, hydraulic pressure then can be oppressed catch conduit mouth is sealed in the expansion capsule, and saline can not reflux in the capsule, and saline still can inject in the capsule under syringe pressure.

This utility model is owing in the inflexion point capsule, be provided with catch facing to conduit mouth, and the interior hydraulic pressure of expansion capsule can be oppressed catch conduit mouth is sealed, saline can not reflux in the capsule, and still available syringe injects normal saline in the capsule, so medical personnel can use than the thick needle water filling by injection kettle, conduit, thereby reduce medical personnel's working time, time saving and energy saving, and be used for inserting repeatedly the injection kettle of syringe needle, need not reinforce reinforced seal, liquid can not outflow yet, corresponding can reducing cost.

This utility model concrete structure is provided by following examples and accompanying drawing thereof:

Fig. 1 is this utility model structural representation

With reference to Fig. 1, the injection kettle 1 that this soft tissue expander is made by medical silica-gel, conduit 2 and expansion capsule 3 are constituted, and an end of conduit 2 connects injection kettle 1, and the other end is connected with expansion capsule 3, conduit 2 with expand capsule 3 place that is connected, be provided with non-return valve.

Described non-return valve is in conduit 2 and expansion capsule 3 joints, on the inwall of expansion capsule 3, is provided with catch 4, between the inwall of catch 4 and expansion capsule 3, removes the slit 5 of leaving 1-2mm, leads to outside the conduit, and remainder is all closely connected.

Claims

1, a kind of medical soft tissue expander, injection kettle (1), conduit (2) and the expansion capsule (3) made by medical silica-gel are constituted, one end of conduit (2) connects injection kettle (1), the other end is connected with expansion capsule (3), its spy is characterised in that: conduit (2) and expansion capsule (3) place that is connected are provided with non-return valve.

2, by the described soft tissue expander of claim 1, it is characterized in that: described non-return valve, be in conduit (2) and expansion capsule (3) joint, on the inwall of expansion capsule (3), be provided with catch (4), between the inwall of catch (4) and expansion capsule (3), remove the slit (5) of leaving 1-2mm, lead to outside the conduit, it is all closely connected in surplus part.
