Embodiment Construction

[0031] Such as figure 1 and figure 2As shown, a surgical extremity operation has both blood-expelling and hemostatic functions, including an elastic contraction ring 1, the outer surface of the elastic contraction ring 1 is composed of an inner ring surface 2 coaxially arranged, an outer ring surface 3, and a The inner ring surface 2 and the outer ring surface 3 are spliced ​​into two sides 4 of a ring-shaped whole. The width of the inner ring surface 2 is not less than 2 cm. The minimum expansion and contraction diameter of the inner ring surface 2 is 2.5-10 cm. The telescopic diameter is 5-15 cm, and the minimum telescopic diameter is smaller than the maximum telescopic diameter.

[0032] The width of the inner ring surface 2 can be adjusted according to actual needs, and the minimum telescopic diameter and the maximum telescopic diameter of the inner ring surface 2 also need to be designed and determined according to actual needs. Since the limbs of the human body are di...

Abstract

The invention discloses a limb surgical apparatus with the exsanguination and hemostasis functions. The limb surgical apparatus comprises an elastic retraction ring. The outer surface of the elastic retraction ring is composed of an inner ring face, an outer ring face and two side faces, wherein the inner ring face and the outer ring face are coaxially arranged, and the inner ring face and the outer ring face are spliced into an annular whole by the two side faces. The width of the inner ring face is no smaller than 2cm, the smallest flexible diameter of the inner ring face is 2.5-10cm, the largest flexible diameter of the inner ring face is 5-15cm, and the smallest flexible diameter is smaller than the largest flexible diameter. The limb surgical apparatus can achieve the two functions of exsanguination and hemostasis at the same time by means of elastic force of the elastic retraction ring and is simple in overall structure, low in cost, capable of being used safely in a disposable mode, sanitary and easy to use and operate, professional requirements for a user are not high, and thus the limn surgical apparatus is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of medical device design, and in particular relates to a device for surgical extremity operations with the functions of expelling blood and stopping bleeding. Background technique [0002] The blood supply of human limbs reaches the limbs through the heart and arterial blood transfusion, and returns to the heart through the venous blood vessels to complete the blood circulation. When performing surgical operations on limbs, blood vessels may be damaged and cause bleeding. Therefore, in order to prevent blood loss and create a bloodless surgical environment, it is necessary to drive blood from the end of the limbs to allow blood to flow back to the heart. The surgical site is close to the heart for temporary hemostasis, and the blood transfusion from the heart to the limbs is cut off. After the operation, the blood supply to the limbs needs to be restored. To realize this function, certain medical devices an...
