RU2644648C1 - Surgical prick - Google Patents

Abstract

FIELD: medicine.

SUBSTANCE: invention relates to traumatology and orthopedics and can be used to perforate small limb bones when fixing tendons and ligaments to the bone. Surgical prick comprises a handle and needle. Handle is detachable. End of the needle, opposite to the pointed, working end is flattened on both sides. Width of the flattened part does not exceed the size of the diameter of the needle, wherein the flattened end is provided with a through eyelet and is detachably installed in socket formed at the end of the handle, in shape and size corresponding to said end of the needle. Depth of the socket is sufficient to securely fix the needle therein.

EFFECT: technical result consists in facilitating the work of the surgeon, speeding up the operation process and reducing the traumatisation of tissues.

Description

The invention relates to medicine, specifically to traumatology and orthopedics, and can be used for perforation of small bones of the extremities when fixing tendons and ligaments to the bone.

Known suture instruments for conducting suture material for connecting a damaged, or affected during plastic, tendon, or ligament, consisting of a pointed rod with a hole for the thread [1].

Known surgical instrument - an awl [2], with which channels are made in the phalanx of the finger through which suture material is passed and bone fragments are connected to each other. They are used to form a canal in a bone or ligament, or tendon, drilling with a Kirschner needle [3] - both of these instruments are removed from the formed canal, and a suture instrument is inserted into the canal - a needle with a thread, which sutures the end of the damaged, or affected during plastic, tendon , or ligaments. It takes time to hold the needle through the formed channel, and it takes a sufficiently long time to remove the edges of the wound with hooks, which causes additional trauma to the tissues surrounding the channel.

The essence of the invention is expressed by a combination of essential features sufficient to achieve the desired technical result, which consists in excluding from the sequence of actions for transosseous fixation of the tendon the stage of removing the awl or knitting needle from the bone, and holding the needle inserted with suture material, which facilitates the work of the surgeon, accelerates the process surgery and reduces tissue trauma.

The surgical awl contains a handle and a needle. The handle is removable. The end of the needle, opposite to the pointed one, the worker, is flattened on two sides. The width of the flattened part does not exceed the size of the diameter of the needle, while the flattened end is equipped with a through eye and is installed, with the possibility of a connector, in a socket made in the end of the handle, corresponding in shape and size to this end of the needle. The depth of the nest is sufficient to securely fix the needle in it.

The design of the split awl provides the ability to conduct suture material through the bone in one puncture, without additional manipulations.

The end of the needle tapered on both sides allows it to be installed in the handle socket without the possibility of turning the handle around the needle during operation.

The width of the flattened part of the needle does not exceed the size of the diameter of the needle to prevent an increase in the opening in the bone, which would weaken the strength properties of the bone.

A through eye at the tapered end allows threading of suture material.

The depth of the nest, sufficient for reliable fixation of the needle, eliminates its kink during the operation.

The design of the device is illustrated by the attached illustrations, where:

in FIG. 1 shows an awl assembled;

in FIG. 2 is a section AA showing the configuration of the socket;

in FIG. 3 - shows the tapered end of the needle in two projections.

The surgical awl contains a removable handle 1 and a needle 2. The end of the needle 3, opposite the pointed, working end 4, is flattened and installed in the socket 5, made on the end of the handle 1. The flattened end 3 of the needle 2 is equipped with a through ear 6 for threading the suture material.

Awl is used as follows.

An incision is made on the skin of the finger, the proximal end of the damaged or affected during plastic, tendon, or ligament is secreted, and stitched with suture material. Next, the wound is bred with hooks, exposing the bone of the phalanx of the finger in the fixation zone. A channel is made into the bones with an awl, the removable awl handle 1 is removed, while the flattened end 3 of the needle 2 with the through eye 6 is exposed, into which the suture material is threaded. A straight needle 2 with suture material is brought to the opposite surface of the phalanx, with the tendon leading to the bone. The tendon is fixed. Suture the wound.

Claims (1)

Surgical awl, containing a handle and a needle with a pointed working end, characterized in that the needle end opposite the pointed end is flattened on two sides, has a width of the flattened part not exceeding the diameter of the needle, made with a through eye and installed in the end face of the removable handle in the socket , which corresponds in shape and size to the tapered end and is made with a depth sufficient to securely fix the needle and to exclude its fracture.
