Abstract

The present patent comprises a special model of needle (1) for surgical procedures which is easy to insert and to remove, and which allows greater efficiency and safety and a reduction in working time, especially in the field of veterinary surgery, and it is formed by a square-section segment base (2) connected to an inverted frustum of a cone (3) with a larger base connected, via an intermediate re-entrant section (4) with an inverted-arc depression, to the larger base of a further frustum of a cone (5) where the hole (6) for the passage of the thread is located, the smaller base thereof being connected to a tapered conical point (7), forming an inverted-arc coupling (8).

Description

"PROVISIONS INTRODUCED IN NEEDLE

SURGICAL "

This utility model patent, which relates to the hospital medical equipment industry, particularly that dedicated to the production of surgical instruments, relates to a special model needle for surgical procedures that is easy to fit, remove, improve efficiency, safety. and decreased working time, especially in veterinary field surgeries.

In the current state of surgical instruments, particularly those used in the field of veterinary medicine, dedicated to performing tissue sutures on animals, some types of needles are better known and used, the most commonly known being the "S" needle, which it's very simple. This "S" shaped needle is generally used when resting on the palm of the hand and forced against the tissue to be sutured. As the biological tissue (usually leather) is resistant and flexible, the force required to perform the perforation at the time of suture, this needle tends to dislocate or break when attempting to perforate, often causing injuries to the hand where The needle is supported, which causes discomfort to the surgeon.

The present utility model patent innovates in this regard by presenting a needle model, specially developed for use in a special needle holder, which optimizes its use and offers the surgeon greater practicality in use, comfort and eliminates virtually any possibility of discomfort. in its use. It is a needle model, which can be either straight or curved, containing a square section fixation base for hollow hole fixation, with the same section, arranged in a needle holder. Fixing base it is connected to an inverted cone trunk segment that terminates at the edge of an arcuate recess and continues conically to the tapered tip, which has a slightly larger diameter forming an arc coupling with the smaller taper base.

In this needle the square fixation base, once coupled to the needle holder, prevents it from rotating about its axis and the groove allows its insertion in the socket end of the needle holder facilitating the removal of the needle after suturing with the minimum effort.

The needle arrangement for surgical procedures, object of this utility model patent, can be better understood by referring to the accompanying figures, which are part of this descriptive report and contain numerical references together with the description of their technical particularities. These figures, which do not restrict their configuration as to their dimensions, proportions and any types of finishes inserted or the scope of their practical application.

Figure 1 is a perspective view of the straight type needle.

Figure 2 is a perspective view of the curved type needle.

Figures 3 and 4 are illustrations of the mounting of the needle in a needle holder and the locking end of the needle where it is attached.

According to these figures and their numerical references the object of this utility model patent relates to a special straight needle (1) or curved (IA) model for use in surgical procedures, particularly in the veterinary field, formed by a base. of square section segment (2) ending near the minor base of an inverted cone trunk (3). Inverted cone trunk (3), whose larger base is connected, through an intermediate recess (4) with inverted arched recess, the larger base of another cone trunk (5), where the through hole (6) of the wire is located, the smaller base of which is connected to a tapered tapered tip (7) of slightly larger base diameter forming an inverted arc coupling (8).

Said model to be attached to a special needle holder (9) at whose needle attachment end (1 or IA) must contain a hollow-hole housing with square inner section (10), the needle (1 or IA being ) fixed by an oblong pressure ring.

In practice the present needle model allows the use of the curved needle (IA) in two distinct positions (aligned or perpendicular) without the needle turning under stress and its pull or removal of the tissue incision being facilitated through a slot of insert inserted into the intermediate recess (4).

Claims

CLAIM

"NEEDLE PROVIDED FOR SURGICAL PROCEDURES", a special needle model for easy-to-remove surgical procedures that allows for greater efficiency, safety and reduced working time, especially in veterinary field surgery, fixed to a needle holder ( (9) The special needle-locking end (1 or IA) of which there is a hollow-hole housing with square inner section (10), the needle (1 or IA) being fixed by an oblong pressure ring, characterized in that it is formed by a square section segment base (2) which terminates near the smallest base of an inverted cone trunk (3), the largest base of which is connected, through an intermediate recess (4) with inverted arc recess, to the base larger than another cone trunk (5) where the through hole (6) of the wire This cone trunk (5), whose smaller base is attached to a tapered tapered tip (7), of slightly larger base diameter, forming an inverted arc coupling (8).
