The needle holder of Hegar, or Mathieu, or Troyanova, or Castroviejo is intended to hold the needle when applying the necessary surgical sutures, which means the requirements for this instrument, must be observed very strictly. Over the centuries of the development of surgery, medical practitioners have developed several designs of such surgical instruments. They differ in some features of its various parts.

Many global companies involved in the production medical equipment and instruments, they also produce surgical instruments, such as, for example,Mayo-Hegar needle holder. For absolute sterilization, it is most convenient to use materials that do not lose their qualities when autoclaving, irradiation or treatment with disinfectants. That's why surgical instruments are made mainly from high quality of stainless steel medical purposes.

What should the needle holder be like?

The Hegar needle holder has several varieties that allow you to use this type medical instrument for various surgical interventions. But whatever it is, its quality must be impeccable. What requirements do surgeons place on such an instrument?

• absolute precision in needle stroke at all stages of work;
• simple algorithm for capturing and releasing the needle;
• the needle in the jaws (working parts of the needle holder) must be securely fixed;
• comfortable, effective work on various fabrics;
• ergonomics and stability of the tool;
• safety of the needle during operation, as a result of the absence of the “cutting effect of the jaws”;
• long-term operation while maintaining all working qualities;
• balanced design, eliminating the occurrence of a “leverage” effect and rupture of connected tissues.

Types of needle holders

The Hegar needle holder is a tool that assists the surgeon in suturing. It allows you to work on different fabrics and organs, both on the surface of the body and in internal areas, for example, in gynecology. Therefore, it is not surprising that such a surgical instrument is available in several versions. For example, needle holder Olsen Gegara(Olsen Hegara) has special scissors on its jaws designed to cut off the working thread.

Also, the surgeon’s instrument for suturing can have long or shortened handles, different reliefs on the jaws - mesh or inclined notches, a longitudinal groove, an abrasive monolayer. In some forms of needle holders, the jaws are made of removable parts made of soft alloys. The needle in the working parts of the needle holder must be correctly fixed - in the middle of the jaws, in order to prevent tissue damage due to an unstable position of the needle during operation or from breakage of the needle itself as a result of the “chopping effect”.

Also, the surgeon's suturing instrument may have a special lock - a ratchet, which allows you to fix the specified position of the handles and jaws. Needle holders without a ratchet are often used for. In its design, the Hegar needle holder is somewhat reminiscent of ordinary office or household scissors, and just like scissors, very often its types are equipped with rings at the ends for convenient placement and reliable fixation in the surgeon’s hand.

Specifications

The product may look like forceps or scissors. The latest modification is more convenient. Both of them have a lock (crack) for securely fixing the jaws in the desired position. In the absence of this element, the specialist has to fix the handles himself - with his hands. At the same time, surgical needle holders without ratchets are good for working with atraumatic equipment. The design of the jaws (main working parts) can be detachable or one-piece. In the first case, the removable parts are made of softer alloys than the structure itself. If the model has an enlarged thumb ring, the handle is shortened compared to standard-length tools.

Three types of notches can be applied to the working surfaces: longitudinal groove, cross-shaped, transverse. They can also be replaced by a diamond layer. For greater strength, surgical needle holders are reinforced hard alloys. Pakistani products are different best performance, although in many models from Russian manufacturers Stainless medical steel is superior in quality. The service life corresponds to what is stated by the manufacturer.

Advantages

Every surgeon knows that buying a needle holder is important good quality. This tool is indispensable for almost any surgical intervention that involves suturing. Basic requirements that a general surgical needle holder must meet:

• reliability of needle fixation;
• absence of the so-called “cutting effect”;
• precise positioning of the needle when creating stitches and forming knots;
• convenience for the practitioner (ergonomics, stability when positioned in the hand);
• quick and easy manipulation (including needle capture/release);
• versatility when sewing different fabrics;
• high performance properties throughout the entire period of use;
• resistance of working surfaces to mechanical damage and biological fluids;
• high quality of workmanship (smoothness, absence of burrs, etc.);
• ease of use when making deep and surface seams, without changing needle holders.

In modern medicine, a microsurgical needle holder is most often used when suturing blood vessels. A similar instrument is indispensable in ophthalmology. And for ease of manipulation, such tools have slightly different dimensions, but the balance of the design must be precisely preserved.

Currently, there are more than 30 models of needle holders that provide stitching of fabrics in different conditions. When selecting the desired type The needle holder must be guided by the size of the needle and the features of the intervention. The surgeon's hand together with the needle holder forms complex design to perform actions high precision. That’s why it’s so important to hold a high-quality and convenient tool in your hand.

Needle holder is a surgical instrument that is used to pass through tissue when suturing.

Needle holders must strictly comply with the requirements for them:

• Reliability of needle fixation in the working part of the instrument
• Easy to grip and release the needle
• Ensuring accurate needle placement at all stages of suturing
• Avoiding the “chopping effect” when fixing the needle
• Versatility when joining fabrics with different properties
• Harmonious design, which prevents the occurrence of a “leverage” effect
• The ability to connect the edges of the wound not only on the surface, but also in the depths of the wound with the same instrument
• Confident position in the surgeon's hand
• Full compliance with all ergonomic requirements
• Maintaining performance properties for a long time

In accordance with design features, the working ends of the needle holder should be short, massive and blunt-ended. The cuts on them can be in the form of longitudinal grooves, transverse or cross-shaped notches. The notches can be replaced with a “diamond” coating, which is applied in the form of a monolayer.

The working parts of the needle holder are called branches. Their design can be either solid or in the form of removable parts made of soft alloys. A special lock, the ratchet, fixes the handles of the needle holders in a given position. Some types of needle holders do not have such a lock, and the handles are held with closed fingers. Needle holders without a lock are used when working with atraumatic needles. To perform the necessary manipulations, two handles usually end with rings.

Most needle holder designs are oval shaped and have the same parameters. There are also models in which the thumb ring is larger and the handle is slightly shorter.

The position of the standard needle holder in the surgeon's hand should be as follows:

• the phalanges of the 1st and 4th fingers are inserted into the rings of the needle holder;
• the tip of the second finger fixes the place near the axis of the intersecting handles.

It turns out that the fingers form a triangle shape. It is not recommended to thread the nail phalanges of the first and second fingers into the rings of the needle holder, since the axis of rotation will pass through the ends of the fingers, as a result of which the position of the needle holder will be unstable.

In practice they are used various sizes needle holders depending on the area of ​​surgery. For example, a microsurgical needle holder differs from a conventional one in the presence of a spring surface and size work surface, the length of which does not exceed 1 cm and width - 1 mm. The vascular needle holder is used to apply a vascular suture. Its total length is about 100-200 mm, and its width is 1-1.5 mm.

As you can see, there are many options for needle holders, different in structure and scope. The main ones are the needle holders of Hegar, Mathieu, Troyanov, Barraquer and Codivilla.

Hegar needle holder- classic straight needle holder. It has different lengths and widths of handles, as well as different notches on the jaws. Hegar needle holders are often used with handles of different lengths.

Codivilla needle holder used to hold straight surgical needles when suturing tendons. It has a complex bend in one of the handles, which increases the ease of handling the tool.

Barraquera needle holder used in ocular microsurgery. It is distinguished by the presence of hemispherical recesses at the ends internal surfaces jaws, due to which the needle is held at any angle to the axis.

Zand needle holder serves to hold eye surgical needles when applying sutures. It is a combination of tweezers and a clamp, with one jaw of the instrument being common to them.

The Langenbeck needle holder is a needle holder with lead plates on the working jaws, which provides more reliable fixation of the needle.

Needle holder Mathieu used to hold a surgical needle while suturing. It is equipped with springy handles and a ratchet lock, which opens when the handle is further compressed.

Troyanova needle holder serves to hold surgical needles when suturing. The locking ratchet is located on the end of the handles, so it can be unfastened with the V finger of the hand.

Needle holders Troyanov and Mathieu have such a design of handles, the fixation of which is carried out by squeezing the fingers of the hand. In this case, the tool lock rests against the palm, which does not exclude the possibility of damage to surgical gloves and even the surgeon’s palm. Such disadvantages make it difficult to use these needle holders in surgery.

Thus, the choice of a needle holder is largely determined by the size of the needle and the characteristics of the intervention. The more delicate and technically complex the operation, the more elegant the needle holder should be. The smaller the needle, the smaller the needle holder should have. The needle holder is an extension of the surgeon’s hand, so a high-quality needle holder will increase the chances of a successful outcome of the operation and reduce the likelihood of complications.
