Abstract

The utility model relates to a heterotype polytetrafluoroethylene wafer for the reconstruction of a deep vein valve. The utility model has rectangle, wedge shape, inverse wedge shape, and spindle shape. The circle diameter of a pipe can be constricted by one third in an annular way by the utility model for different patients and different positions. 5-0 atraumatic sutures cause both sides of the utility model to be combined, sutured, and fixed. Big and small saphenous veins and varicose agglomerate superficial veins are processed properly. In an operation, the utility model is used for detecting annular retractive remote vein pressure (P is smaller than 0.01). After the operation, contrast agents are viewed in a contrast way to be blocked at an annular retractive side, and not to back flow towards to a remote side. The function of the valve can be generated, and a vein cavity does not need to be cut open. The utility model has the advantages of small wound, little complication, and satisfactory curative effect.

Description

Rebuild the special-shaped teflon plate of dark vein valve

This utility model relates to the design and the manufacturing technology of the artificial blood vessel of rebuilding the deep veins of lower limb valve.

Suffering from the refluence of deep veins of lower limb blood vessel is commonly encountered diseases, severe patient can cause sufficient boots district ulcer, what deep veins of lower limb flow backwards is main former because wall of vein expansion and valve structure destroy, but both reciprocal causations are mutually promoted, the Therapeutic Method of common employing is a: popliteal vein Ji Ban plasty, two kinds of methods of band lobe venous graft, operation wound is big, the damage wall of vein, easily form thrombosis, complication is many.

The purpose of this utility model provides a kind of being wrapped in outside the dark vein, can effectively prevent the special-shaped teflon plate of the dark vein valve of reconstruction of backflow of blood.

The purpose of this utility model is achieved in that teflon plate has rectangle, wedge shape, falls wedge shape and spinning shaft shpe.The rectangle teflon plate is used for the deep vein pipe

Shape, wedge shape teflon plate are used for the deep vein pipe and are

Shape, the teflon plate of falling the wedge shape are used for the deep vein pipe

Shape, spinning shaft shpe teflon plate are used for the deep vein pipe and are

Shape.

The utility model has the advantages that, for different patients, different parts, with 1/3 of its Guan Zhoujing of this abnormal shape teflon plate annular constriction, with the involutory sutured in its both sides, large and small saphena and the agglomerating superficial vein of varicose are done suitably to handle with the 5-0 atraumatic suture, the detection ring nearly far-end venous pressure (P＜0.01) that contracts in the art, the postoperative radiography observe to find that contrast agent stops at the ring nearside that contracts, and no longer distad flows backwards, and presents valve sample function.Adopt the contract vein operation of this abnormal shape politef loop not cut off any muscle tendon, must not cut venous lumen, wound is little, and is easy and simple to handle, and complication is few, satisfactory effect, but extensive use.

Below in conjunction with drawings and Examples this utility model is described in detail.

Fig. 1 is this utility model rectangle teflon plate structural representation.

Fig. 2 is this utility model wedge shape teflon plate structural representation.

Fig. 3 is this utility model teflon plate of falling wedge shape structural representation.

Fig. 4 is this utility model spinning shaft shpe teflon plate structural representation.

With rectangle 1, wedge shape 2, fall wedge shape 3, spinning shaft shpe 4 teflon plate, the patient who is used for 152 examples, mean age was at 53.6 years old, the course of disease 6～31 years, clinical manifestation is the superficial veins of lower limb varicose, shank is swollen to be opened, distending pain, eczema, pigmentation, ulcer, the postoperative transference cure, ulcer 4～6 week healing, under TV screen, dynamic observe continuously, dark vein ring contracts and sentences down contrast agent and have rhythm and pace of moving things ground entad to reflux with respiratory movement, use rectangle, wedge shape, fall wedge shape, after spinning shaft shpe politef loop contracted, obvious eddy current and turbulent flow appearred in the visible ring place of contracting, and the spinning shaft shpe politef loop whirlpool, place of contracting, turbulent flow alleviates, ring contracts and locates the slightly expansion of nearside vein, does not flow backwards.Adopt this kind method treatment disease, patient is painful few, and special-shaped teflon plate is not seen any rejection after transplanting.

Claims

Rebuild the special-shaped teflon plate of dark vein valve, it is characterized in that: teflon plate has rectangle [1], wedge shape [2], fall wedge shape [3] and spinning shaft shpe [4].
