Skin cutting equipment for lumbar intervertebral foramen mirror operation

Abstract

The invention discloses skin cutting equipment for lumbar intervertebral foramen mirror operation. The equipment comprises a skin cutting element, a holding part, and a through hole, wherein the skincutting element is a blade with two edge parts symmetrically arranged; the holding part is arranged above the skin cutting element; and the through-hole is formed inside the skin cutting element and the hold part. The interior of the skin cutting element and the interior of the holding part are arranged to be of a hollow structure, guide wires with different diameters can penetrate through the skin cutting element and the hold part with skin of a puncture point as the center; the skin cutting element is arranged to be double-edged, a minimally invasive skin incision with the length of 7 mm-9 mm can be accurately formed with a guide needle as the midpoint, and even if the position of deep fascia of part of obese patients is deep, the deep fascia can be accurately cut Under the guide of theguide needle, so that the defects of channel position deflection and insufficient incision depth in the operation process are avoided. According to the equipment, the skin cutting element and the holding part are integrally designed, so that the danger that in the operation process of an existing detachable scalpel, a blade is clamped by the deep fascia and falls off from a scalpel handle to be left in the body is avoided, operation wounds are reduced, and operation time is shortened.

Description

technical field [0001] The invention belongs to the field of medical instruments, and relates to a skin-opening device for lumbar intervertebral foramen surgery. Background technique [0002] Before transforaminal endoscopic surgery, determine the target position of the target intervertebral disc through fluoroscopy and plan the surgical incision. First, use a 21G puncture needle to reach the target position under the guidance of fluoroscopy, pull out the needle core, place the guide needle into the target position, and exit the puncture With the guide pin as the center, guide rods of different diameters are placed step by step after skin incision to form an ideal surgical approach, and a working channel is established along the guide rod. After the guide pin is inserted in the traditional surgical method, a small incision in the skin, subcutaneous and deep fascia is made with a medical detachable scalpel to facilitate the smooth entry of subsequent surgical instruments.

AI Technical Summary

Problems solved by technology

Ordinary detachable medical scalpels have the following defects when completing this operation. First, it is difficult to completely center the puncture point during incision; , resulting in deviation of subcutaneous and deep fascia incision positions; third, some obese patients have deep deep fascia, and ordinary detachable scalpels are not long enough to incise deep fascia smoothly, resulting in difficulty in entering subsequent surgical instruments; fourth, For some patients with deep fascia hypertrophy, when the deep fascia is incised and the blade is pulled back, the hypertrophic fascia will cause the blade to detach from the handle slot and remain in the body, increasing the surgical risk
