Hemostatic guide sleeve, vascular puncture device, hemostatic device and proximal anastomosis auxiliary system

Abstract

The invention provides a hemostatic guide sleeve, a blood vessel puncture device, a hemostatic device and a near-end anastomosis auxiliary system. The hemostatic guide sleeve includes a guide sleeve front shell, a guide sleeve rear shell and a check valve which is arranged between the guide sleeve front shell and the guide sleeve rear shell; the blood vessel puncture device includes a puncture component and the hemostatic guide sleeve, and the hemostatic guide sleeve is connected with the puncture component for work; the hemostatic device includes a hemostat kneading component, an umbrella-shaped hemostat and a hemostat push component which is cooperated with the guide sleeve of the hemostatic guide sleeve; the near-end anastomosis auxiliary system includes the blood vessel puncture device and the hemostatic device. The hemostatic guide sleeve, the blood vessel puncture device, the hemostatic device and the near-end anastomosis auxiliary system can well meet the puncturing, treatment and hemostasis full-process operation requirements under the near-end anastomosis conditions, and are safe and stable; in the whole operation process, blood can be always sealed in an instrument, the view is thus not affected by the blood in the operation process so that medical staff can see more clearly in the operation process, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to a proximal anastomosis auxiliary medical device, in particular to a hemostatic guide sleeve, a blood vessel puncture device, a hemostatic device and a proximal anastomosis auxiliary system. Background technique [0002] The stapler is the first stapler in the world. It has been used for gastrointestinal anastomosis for nearly a century. It is a device used in medicine to replace traditional manual suture. Due to the development of modern technology and the improvement of production technology, the anastomosis currently used clinically The device is reliable in quality, easy to use, tight and suitable for tightness, especially its fast suturing, easy operation, and few side effects and surgical complications, making it widely favored and respected by clinical surgeons at home and abroad. [0003] In order to improve the working efficiency of the stapler, various types of anastomotic auxiliary devices have appeared, among which t...

Problems solved by technology

[0003] In order to improve the working efficiency of the stapler, various types of anastomotic auxiliary devices have appeared, among which the proximal auxiliary system for treating cardiovascular diseases is more common, such as the proximal anastomotic auxiliary device disclosed in Chinese patent ZL 201520510925.0 , its structure well solves the problem of the inconvenient adjustment of the tube wall clip by the proximal anastomotic auxiliary instrument for minimally invasive coronary artery bypass grafting, but the structure of the device is relatively complicated and the volume is large, so it cannot be applied to various anastomotic environments , and the anastomotic operation also includes puncture opening and hemostasis. This plan does not provide a suitable solution, and there is still a need for greater technical improvement and innovation to meet the various operational needs of proximal anastomosis.
