Description
Technical field
The present invention relates to a kind of heat conducting devices for measuring skin flap of rats nerve recovery.
Background technique
Skin is the maximum organ of human body, and having prevents foreign bodies from invading, and adjusts body temperature, the function such as pain, touching, temperature sensation
Energy.Also often because of soft tissue, underlying nerve damage caused by tumour, burn, knife wound etc..Clinically, skin flap transplantation is treatment soft tissue
Damage unique method.Flap (skin flap) is with self-blood supply, the tissue block comprising skin histology.Tissue lacks
The reparation and reconstruction of damage, histoorgan reconstruction etc. require flap.Mainly there are two aspects for postoperative skin flap transplanting evaluation: shape is repaired
Multiple, sensory recovery.With the development of medicine, prominent question has been not present in the former, but the latter is often not fully up to expectations, gives patient
Daily life brings puzzlement.For the flap of denervation due to a lack of neurotrophy and innervation, flap can be thinning, is prone to wear brokenly
It bursts, the dry tarnish of appearance, numbness etc., and vasomotor disturbances in the flap of total denervation, lead to tissue edema, skin
Skin anti-infection ability is low.In denervation infection flap, the area of septicopyemia lesion and soft tissue oedema is also dramatically increased.Cause
This, flap sensory recovery has extremely important effect and meaning in Clinical Surgery.Flap sensory recovery is evaluated mainly by two
Part forms: morphological observation, Behavior test.Rat dorsum skin layering respectively epidermis, skin corium, subcutaneous tissue,
Fascia under sarcolemma (skeletal muscle) and sarcolemma.
With regard to there are many deficiencies in current flap nerve recovery judgment technology, i.e., it can not accurately judge sensory recovery degree,
Mechanical hyperalgesia stimulates in the prior art, and postoperative rat experiment model reaction is unobvious, different time points, different researcher's operations
Dynamics change greatly, can not criterion and quantity.
Summary of the invention
In view of the deficiencies in the prior art, technical problem to be solved by the invention is to provide a kind of measurement skin flap of rats nerves
