RU165214U1 - DISPOSABLE SURGICAL HOOK - Google Patents

Abstract

A disposable surgical hook comprising a body and a working part, characterized in that the body and the working part are made in the form of two parts, the working part being made in the form of a removable C-shaped hook; three rounded protrusions are made at the proximal end of the body, which are placed in the projection of the vertices of the isosceles triangle to change the C-shaped hook, made with three rounded grooves.

Description

Disposable surgical hook

The utility model relates to the field of medicine and medical technology, namely to surgery, and can be used to capture and displace organs and tissues, mainly in patients with different thicknesses of subcutaneous fat.

The effectiveness of any surgical intervention depends on the reliable capture and displacement of organs and tissues during the surgical operation. The most difficult to capture and displace tissues in patients with morbid obesity.

At the end of the XXI century, minimally invasive methods of surgical operations are widely used. However, small incisions of the skin lead to a small exposure of the surgical wound [Mashkin A.M. The use of mini-access in the treatment of inguinal hernias. Endoscopic surgery. 2013. No1. Vol. 2. S. 66-67.]. The thickness of subcutaneous fat in patients can reach up to 15-20 cm, which creates difficulties in finding formations located in the subcutaneous layer [Darwin V.V. Surgery for morbid obesity. Tutorial. Surgut: Surgut State University Publishing House, 2004. - 63 p.].

We have proposed a useful model for surgical operations in patients with different thickness of subcutaneous fat, as well as in conditions of mini-access.

Exciting, holding and cutting surgical instruments are described [Patent RU 26404 U1 of 12/10/2002; Patent RU 13605 U1 dated 05/10/2000] has a complex structure and is not acceptable for surgical operations in patients with morbid obesity.

For the treatment of vein diseases, a tool made in the form of a rod with a sharp hook at the end is proposed [Patent RU 107685 U1 from 2

August 27, 2011], which has a complex structure and this tool is used only with wide operational access.

Extremely complex gripping, holding and cutting tools are proposed, the working part of which is made in the form of sponges, hooks or blades [Patent RU 13147 U1 from 03/27/2000; Patent RU 13148 U1 dated 03/27/2000], the use of which is impossible in case of mini-access .;

For minimally invasive surgical treatment of degenerative and destructive diseases of the hand, a tool is proposed, the working part of which is made in the form of a hook with cutting sharpening [Patent RU 130829 U1 from 08/10/2013].

The tool is not intended to perform abdominal operations in persons with morbid obesity, and the sharp sharpening of the hook does not allow the capture of pathological formations.

As a prototype, a curved muscle hook was selected [Patent RU 137196 U1 dated 10; 02.2014], used in ophthalmology for ligature on the oculomotor muscle. The proposed tool is used in conditions of mini-access, but the possibility of using it in abdominal surgery for morbid obesity is excluded.

The task of creating a utility model is to design a simple and easy-to-use device for performing operations in patients with various degrees of obesity and the possibility of using it in conditions of mini-access.

The technical result of the proposed device is achieved by the fact that the outer surface of the working part of the device allows you to move fatty tissue, and the inner part to capture pathological formations. The presence of a replaceable working part of various 3

sizes allows you to use the device when conducting operations with different sizes of online access.

The utility model according to the technical solution includes a housing and a working part made in the form of two parts, moreover, the working part is made in the form of a removable C-shaped hook; three rounded protrusions are made at the proximal end of the body, which are placed in the projection of the vertices of the isosceles triangle to change the C-shaped hook, made with three rounded grooves.

The proposed utility model is illustrated by graphic material.

The figure 1 shows the details of the device, where 1 is the body, 2 is the distal end of the body serving as a handle, 3 are rounded protrusions at the proximal end of the body, 4 are rounded grooves on a removable C-shaped hook, 5 is a removable C-shaped hook.

The figure 2 shows the location of the grooves on a removable C-shaped hook, where 4 are rounded grooves located in the projection of the vertices of the isosceles triangle, 5 is a removable C-shaped hook.

An example of the practical use of the device.

Patient A., 60 years old, from November 16, 2014 to November 23, 2014 was in hospital with a diagnosis of Gallstone disease. Chronic calculous cholecystitis. Obesity 2 degrees (BMI 38 kg / m2). Hypertension 1 st, 2 st, risk 4, heart failure 0, FC 1. Type 2 diabetes mellitus, target glycated hemoglobin level of less than 7%. Received as planned for. surgical treatment at the Regional Clinical Hospital No. 1.

November 17, 2014 under ETN, an operation was performed - cholecystectomy, drainage of the abdominal cavity. Intraoperatively - gall bladder calculi. B. During the operation, a disposable surgical hook is used. The postoperative period was uneventful. Dressings were performed daily, postoperative 4

the wound is clean, the joints are well-off. Abdominal drainage removed on 11/21/2014. The patient was discharged in satisfactory condition for outpatient treatment. During dynamic observation during the year, complications of surgical treatment were not detected.

The proposed utility model is convenient to use, allows the displacement of fatty tissue by the outer surface of the removable C-shaped hook, and the inner surface is the capture of a pathological formation.

The proposed utility model is implemented on the basis of Design Bureau No. 1 and 2 of Tyumen. Conducted 16 operations with a positive effect.
