Abstract

A scalpel with a predetermined cutting depth, comprising a handle, a neck, a working part with a cutting edge and an abutment located at the base of the cutting edge, characterized in that the cutting edge and abutment are placed on the same axis and are made at an angle of 90 - 130 k to the axis of the scalpel handle, scalpel width in its working part at the level of the cutting edge 1 - 0.95 of the width of the handle, and the distance from the stop to the end of the cutting edge is 3 mm.

Description

THANKS TO THE QUESTION OF THE DEPTH OF THE DECISION

The utility model relates to medicine, namely to cutting surgical instruments in laparoscopic serosomyotomy.

known scalpel / 1 / with a given depth section, containing a handle, a neck and a working part with a cutting edge

sickle shape.

The closest analogue is a scalpel with a predetermined GJ: a dissected bin / 2 / containing a hook, a neck and a working part with a concave sickle-shaped cutting edge, the base of the working part is provided with a stop in the form of a protrusion from the side of the cutting edge located at its base.

The width of the scalpel in its working area at the edge level is 0.5 of the handle width,

A scalpel with a given depth of dissection reduces tissue trauma due to a precisely defined depth of dissection, but does not provide the possibility of using it when performing laparoscopic serosomyotomy, since, in this operation, the serous and muscle layer should be clearly dissected.

A scalpel is proposed, the design of which solves the problem by changing the shape and aspect ratio of the elements.

A scalpel with a predetermined cutting depth contains a handle, a neck, a working part with a cutting edge and an emphasis located at the base of the cutting shred, characterized in that the cutting head and stop are placed on the same axis to be made at an angle of 90-130 ° to the axis of the scalpel handle. The width of the scalpel in its working part at the level of the cutting edge is 1.0-0.95 widths of the handle, and the distance from the stop to the end of the cutting edge is 3 w / i.

The scalpel is made of stainless steel, titanium alloys of any type of material that is suitable for the human body.

Scalpel parsing in statics:

The scalpel consists of a handle 1, a neck 2, a working part 3 with a cutting edge 4 in the form of a needle and an emphasis 5 in the form of a protrusion located at the base of the cutting edge. The cutting edge 4 and the stop 5 are placed on the same axis and are made under. Angle 90-130 to the axis of the scalpel handle. The distance from the stop 5 to the end of the cutting cut / knife 4. is determined by the thickness of the muscle and serous layers of the thick lump and does not depend on the size ratio of the scalpel itself. The width of the scalpel in the working part at the level of the cutting edge is 1-0, .95 of the width of the handle.

The figure shows a scalpel,

The scalpel is used in the treatment of diseases of the rectum by the method of laparoscopic serosomzhotomy.

) is carried out under anesthesia. -After treatment of the anterior abdominal wall, two piercing of the brinum cavity is performed; Through l-ys) a laparoscope connected to a video camera, information about the abdominal organs / on the TV screen is introduced into the bruise cavity through the 2nd stool. A preliminary scalpel is introduced. Under the control of the eyes / through the screen /, oerosomyomy is performed by pressing the scalpel handle with your hand. The incision begins between the two lenti of the colon / between the mesenteric margin / above 2-3 cm from the pelvic peritoneum to the top up to 25-30 cm. Then, the transverse incisions along the mesenteric margin in the shakglate order of the sacrum are up to 3 cm, between the incision the distance is up to 10 cm / in total up to 10 times /. Then remove the horse and the operation is completed. 1 | ale of this operation in reducing intracranial pressure with dissection

f f / f the orenous muscle layer of the colon / without damage to the mucosa /. Advantage - replace large cuts on the anterior abdominal wall up to 25 cm, with two punctures with diameters of up to 0.5 ohm, this excludes ventral hernias and adhesive disease in the postoperative period. Patients are discharged home after 3 hours. Disability is 7-10 days.
