The health of the person and sometimes his life depends on the accuracy of the surgical intervention. A set of tools for bone surgery refers to

as a special device necessary for specific operations. The presence and proper condition of this kit allows the surgeon to carry out all necessary manipulations.

Tools for operations

A set of tools for bone surgery is an additional tool that does not replace the general-purpose tools needed for any operational measures, but it allows you to provide procedures that are difficult to carry out without such adaptations. The ability to properly assess the need for each instrument is the professionalism of a doctor and assistant medical worker.

The essence of the surgical instrument

The surgical instrument as such is a special tool and device for surgical intervention in the human body. It is subdivided into general surgery, which is nece

ssary for any operational effect, and special. Special devices in turn are divided into the following groups: obstetric and gynecological, neurosurgical, ENT, ophthalmologic, orthopedic( including resuscitation and traumatology), transplantation, microsurgical, dental and urological.

Tools for operations

Structurally, such devices can consist of one simple object( for example, a scalpel) or look like a complex device with an electric or pneumatic actuator. By their functional features, they are divided into the following varieties:

  • Bandwidth: the study of narrow channels and their expansion.
  • Clamping: I am going through the vessels, keeping organs and needles in the process of surgery.
  • Prickly: Provides drainage or puncture for insertion.
  • Extend( displace): disassembly of organs, extension of cuts.
  • Cutting( chopping, crushing): for cutting of fabrics, resection, cutting and other influences.
  • Connect: Used for the restoration of truncated fabrics.
  • Typically, the operating tool is made with nickel-plated or chromium-plated steel, stainless steel of chromite structure, brass or titanium alloys. For the specific purpose, the following special sets are allocated: for work on bones;amputationstretching of the skeleton;trepanation of the skull and bones with osteomyelitis;metal osteosynthesis;operations on the abdominal cavity, chest and liver;tracheostomy;excision of the gastrointestinal tract.

    Surgical Instrument

    Tools for operations A general set of surgical instruments is required for any surgical effect. It includes the following devices: a tool for cutting tissue;devices for stopping the bleeding;devices for fabric bonding procedure;auxiliary tools.

    Cutting toolkit consists of scalpels and scissors. Scalpel is an acutely sharpened instrument for carrying out a tissue cut or tissue removal.

    Special scissors can have a sharp sharp shape or curved blunt form( Cooper's scissors).To work in deep wounds apply long scissors with sharpened ends.

    Blood pressure devices are used as clips and ligature needles. The most common clamps are Bilrota( with a knotted brush) and Koher( with teeth).Clamps Bilrota are less injurious to fabrics, but the Koehler clamps provide more reliable fixation. Clamping small vessels is used with clamping knots - mosquitoes. Ligature needles are designed to feed the thread under the bowl. Instead, a dissector-a tool for tissue separation and a ligature-can be used.

    Tools for operations

    Connecting tools in the form of needles and needle holders are used to restore the integrity of fabrics. Nipple holders are available in several types, including padding to exclude rotation of the needle. The needles are mainly two varieties - round and cutting. The latter type is intended to provide stitches on tough fabrics: skin, tendons or muscles, where efforts are required to pierce them. In addition, it is possible to allocate the atraumatic type needles( with a thread embedded in the needle-tip), which are used to restore vessels.

    The auxiliary tools include tweezers, hooks, probes, pincers, corkscands, syringes. Pins of different lengths are used to hold tissues. Hooks( dull and sharp) are used to disassemble the wound;they can be with a locking lock. Korncang is designed to remove the wounds and drainage, as well as tampons. The mandatory surgical kit includes syringes of 1-20 ml type Records and a syringe of Lümer and a capacity of more than 100 ml - a syringe of Zhan.

    Bone Operations Kits

    Bone surgery tools are part of an orthopedic toolkit specifically designed for surgical procedures with bones, tendons, and muscles, and includes devices for orthopedic and traumatic measures.

    Tools for operations

    For their functional purpose, they are divided into several main categories.

    Holders are designed to capture, fix and hold bone fragments and fragments. The main representatives of this group are tongs and bones. Bone forceps are used to keep bone fragments;Sequential type of tweezers - for capturing the fragments. In order to fix bone fragments and keep them in the course of osteosynthesis, the following owners are used: the Lambotta device, the trident apparatus of the screw type and some others. Depending on the size of the bone, the type of injury, the features of the wound and the technique of surgery may be taken bone holders of different sizes, as well as straight or curved shapes. To remove the fragment from the wound is a dull, single-hook hook.

    Acutely sharpened tools for cutting, cutting, biting, sawing, drilling and other bone operations are used to directly influence the bone. The buckling and dissection of the bone is carried out using a flat and chip bit. A flat piece can be a one-way or two-sided edge.

    The stinging of the germs, alignment of the edges of the bone fragments is carried out by the tufts( tweezers) of the types of Lüer( with sponges in the form of a gutter) and Liston( with sponges of direct type).The nippers can be straight and bent in different directions( along a plane or a rib), and also have hinges with high mobility in two planes. For sawing bones are used saws of frame, arc and wire type( saw Gili).The formation of bone graft is carried out using a circular saw type - double or single, having an electric drive.

    Operations on the tendons, muscles and tissues surrounding the bones, are carried out using the following tools: tenotomes, hooks for tendons, knives for amputation. In the course of operations of plastic nature on the kite tendons, a set of pink is used that includes raspots for tendons, tenotem, sew, a conductor, a tool for offshores, and buds. For protection of fabrics from damage during operations use elevators and retractors.

    Auxiliary tool for bone surgery is intended for various operations. When working with bits it is impossible to do without hammer, various types of which are included in the set for bone operations. Fastening of bone parts is carried out with the help of various types of fixators. In the case of fractures of long bones, the internal fixation is carried out by the elements of Dubrov, Kunchcher, CITO, etc. In the set for bone attachment includes the following devices: a set of rods, drills, grips, chisels, hooks, pliers, nozzles, shovels, impactors and extractors. When joining the bones, apply bolts, tapes, plates, screws, nails. Special nails of the trilateral type are fastened using the devices of Petrov-Yasnov or Kaplan.
