Description

Ring holder for heart valve forming ring

Technical Field

The invention relates to the technical field of medical equipment, in particular to a heart valve forming ring holder.

Background

In prosthetic heart annuloplasty ring implantation procedures, the observation of changes in leaflet shape and position is a key factor affecting the quality of the procedure. However, the connecting part of the handle of the annuloplasty ring holder of the artificial heart valve may obstruct the surgical field of the operator, become a blind area, and are inconvenient for the operator to observe and adjust the anterior leaflet, thereby affecting the surgical effect. The artificial heart valve forming ring is made of a metal frame, silica gel, polyester threads and polyester cloth. For most patients in need of prosthetic heart valves, surgical procedures are used to implant the prosthetic heart valve annuloplasty ring into the body. During the surgical procedure, the surgeon may suture the annuloplasty ring to the tissue of the human body with the aid of the prosthetic heart annuloplasty ring holder holding the annuloplasty ring.

During heart surgery, an operator can place the annuloplasty ring into the patient by means of a prosthetic heart annuloplasty ring holder, and adjust the position of the annuloplasty ring by the annuloplasty ring holder, so as to conveniently suture the annuloplasty ring with human tissue. Wherein, in order to facilitate the operation of the operator, a handle is required to be connected with the artificial heart valve annuloplasty ring holder, so that the operator can adjust the position of the artificial heart valve annuloplasty ring holder by holding the handle. The existing ring holder has complex structure and more components, and affects the vision of doctors; in addition, most clinical ring holders use transparent materials, which can indirectly affect the surgical field due to problems such as refraction or reflection of light.
