Abstract

The invention discloses a blood vessel traction device used for hand surgery department microsurgery. The blood vessel traction device comprises a movable element, two groups of circumferential fixingelements, a power component and a driving component, wherein the movable element is fixed on the upper end of a traction element; the two groups of circumferential fixing elements are independently arranged on two sides of the movable element; the power component is connected to the circumferential fixing elements; and the driving component is installed on the movable element and is connected with the power component. The traction device can drive a rack to move through an air cylinder so as to drive a gear to rotate, has a self-locking function and is high in safety, a rotary shaft is driventhrough the gear to rotate, and the rotary utilizes gear speed reduction to drive a rotation ring and runners arranged on the circumference to deflect for an angle; and after the runner and an arc-shaped clamping element are separated, a pressure spring is cooperated with a casing pipe and a telescopic element to drive the arc-shaped clamping element to mutually gather to clamp blood vessels, theblood vessels of different diameters can be clamped, and the movable element then drives the whole blood vessels to move to realize a traction function.

Description

technical field [0001] The invention relates to a medical device, in particular to a blood vessel retractor for microsurgery in hand surgery. Background technique [0002] The vascular retractor is used in microsurgery when suturing blood vessels. It is necessary to control the tension of the arteries to a certain extent, so that both sides of the blood vessels need to be repaired, so that the two sections of the two blood vessels can be disconnected without tension. Separate a certain distance, so that when suturing, the blood vessels on both sides are pulled together, so that they can be sutured. [0003] At present, most of the existing vascular retractors are used for adaptive fixation according to the vascular parameters of patients with different physiques, and the clamping operation is laborious, and cannot achieve efficient and fast vascular fixation. Contents of the invention [0004] Based on the deficiencies in the prior art mentioned in the background art abov...
