Abstract

Slot applicable to valves of surgical use intended for coupling to a valve holder, characterized in that it comprises a through cavity (1) defined by a first straight section (1a) of entry that extends until reaching a second straight section (1b) presenting a change of direction, the second section (1b) having an angle of inclination of approximately 10º and 20º with respect to an imaginary longitudinal central axis of the leaflet while the first section (1a) has a angle of inclination approximately between 10º and 20º with respect to an axis perpendicular to the previous imaginary axis.

Description

Slot applicable to surgical use leaflets.

Object of the invention

The present invention patent application Its purpose is to register a slot applicable to leaflets of surgical use that incorporates notable innovations and advantages compared to the current fastening systems of leaflets to valve holder

More specifically, it refers to a slot for a leaflet intended for coupling to a valve holder

Background of the invention

Currently, in the technical field of surgery is known the use of leaflets for incisions, which are usually placed in an articulated or fixed frame together with other leaflets properly distributed in order to maintain the open incision during a surgical operation. Such leaflets they consist mostly of a metallic sheet body with a spatula-like shape and are fixed to a valve holder through various grooves of shapes different.

However, this fixing system presents the main drawback that there is a possibility that it is not compatible with a particular type of valve holder known, so there is a possibility that you have to use different leaflets of the same design but with different slots to fit different types of valve holder

Description of the invention

The present invention has been developed with the in order to provide a slot applicable to surgical leaflets that resolves the aforementioned problems, providing, in addition, other additional advantages that will be evident to from the description that follows.

The slot applicable to surgical leaflets for coupling to a valve holder of the present invention, essentially characterized by the fact that it comprises a through cavity defined by a first straight section of entry that it extends until it reaches a second straight section that presents a change of direction, the second section having an angle of inclination approximately between 10 ° and 20 ° with respect to an axis imaginary longitudinal center of the leaflet while the first section has an inclination angle approximately between 10 ° and 20 ° with respect to an axis perpendicular to the previous imaginary axis.

Thanks to these characteristics, you get a advantageous fixing system that is simple to make easy the coupling of a leaflet to any type of valve holder currently existing in the market, allowing the multiple possible positions of the leaflet and not in no case affects the anatomical region of the patient.

According to another aspect of the invention, the second section an inclination angle preferably of 15 ° with respect to a imaginary central axis of the leaflet while the first section it has an inclination angle preferably of 15 ° with respect to a axis perpendicular to the anterior imaginary axis.

Preferably, the through cavity is arranged in a prolongation of the valve substantially perpendicular to the section of the leaflet that is in contact with the Patient anatomy during an operating position.

Advantageously, the second section of the cavity It has a curved section at its end.

Other features and advantages of the slot object of the present invention will be apparent from the description of a preferred but not exclusive embodiment that it is illustrated by way of non-limiting example in the drawings that are accompany, in which:

Figure 2.- It is a side elevation view of the previous figure; Y

Figure 3.- It is a perspective view of five different leaflets that include the groove of the present invention.

Description of a preferred embodiment

As shown in Figures 1 and 2, the slot applicable to surgical leaflets of the present invention adaptable to all types of valve holders conventional type comprises a through cavity (1) defined by a first straight section (1a) of entry that extends until reaching a second straight section (1b) presenting a change of direction, the second section (1b) having an angle of inclination approximately 15 ° from a longitudinal central axis imaginary of the leaflet while the first section (1a) has a tilt angle approximately 15 ° to an axis perpendicular to the anterior imaginary axis. Said second section (1b) It has a curved section (1c) at its end.

In figure 3, different types of valves (2) each of them specified for application in different sections of the anatomy of the human body during the performing a surgical operation that include at one end or  prolongation of the groove described in the present invention.

The details, the shapes, the dimensions and others accessory elements, as well as the materials used in the Slot manufacturing applicable to surgical use leaflets of the invention may be conveniently substituted by others that are technically equivalent and do not depart from essentiality of the invention or the scope defined by the claims They are included below.
