Description

It is a kind of for adsorbing the absorber of tissue

Technical field

The present invention relates to medical device applications technical fields, specifically, refer to a kind of for adsorbing the suction of tissue Adnexa.

Background technique

With the reach of science and improvement of living standard, people increasingly pay attention to the appearance instrument of itself, especially in skin In terms of skin, increasingly pay attention to cosmetic result, therefore medical operating gradually moves towards to refine.

Hospital is in surgical operation, and such as the skin grafting of hospital, skin grafting is mainly used for repairing all kinds of surface of a wound (as burning is scalded The surface of a wound caused by wound, wound and the secondary surface of a wound after scar excision etc.), clinical application is extremely wide.

According to surface of a wound position and size, the skin donor site of different location is selected, is needed to be beautiful, skin donor site is often selected in skin pine Relaxation and more covert position, such as groin, Medial upper arm, sublavian or carpometacarpal side.

The processing method of skin graft: skin graft, which removes rear scissors depth face, keeps its smooth, and cuts extra skin graft, and skin donor site can be direct Suture will suture again the surface of a wound after some dermis stayed on surface of a wound excision if be taken as thick split thickness skin graft；

Grafts flap coverage, edge sutures and stays long line, to be wrapped up；

Skin graft is covered with oily yarn, then stacks mesh crocus cloth, after uniformly compressing skin graft, is pricked and is fixed with stayed long knot, make skin graft It is in close contact with compressive region, in favor of skin graft healing.

In the prior art, the mobile skin graft of tweezers generally is being used, but existing tweezers are needed in mobile skin graft First descend skin graft spatula then again to skin graft chucking power, the skin graft between two tweezer handles will be accommodated to median rise by tweezers Firmly, but operation will cause skin graft out-of-flatness in this way, while when the existing tweezers some skin graft tissues of clamping, because dynamics controls Not precisely, the clamping part of tweezers will cause skin graft tissue disruption, is unfavorable for skin graft healing, influences later period skin beauty.

Hospital in surgical operation, as hospital in surgical operation for the excision of tumour, one takes vessel forceps to lift, To achieve the purpose that take out tumour in operative treatment, the disadvantages are as follows: clamp opens mouth when carrying out clamp using vessel forceps When, occupied space is big, and clamp be easy to cause tissue damage, meanwhile, it easily causes tumour to rupture the extruding of knurl, increases evil Property tumour transfer meeting, bring unnecessary pain and heavy financial burden to patient.
