Abstract
A device for controlling operating knife depth and inclination aims to solve the difficulty that feeding depth and inclination of a traditional operating knife are inaccurate to control and prevent fault caused by the inaccurate control. The device is characterized by comprising a gasket, a clamp groove and a rubber pad. The gasket is a rectangular sheet. The clamp groove is a semicircular sheet and integrally made of a hard transparent PVC (polyvinyl chloride) piece. The rubber pad is made of a U-shaped flat rubber strip. During use, the rubber pad is coated at an appropriate position of a knife back of the operating knife firstly, the clamp groove and the gasket are arranged according to the feeding requirements to allow the gasket to the tightly fixed at the knife bit, and operation trajectory of a blade can be controlled. The device is simple to manufacture, low in cost, convenient to use and easy to popularize.
Description
(1) technical field:
The present invention relates to a kind of degree of depth and pitch devices of controlling the scalpel feed and belong to A61B19/02 by International Patent Classification (IPC) (IPC) division; Human life need part, (A61) medical science or branch of veterinary (A61B) diagnosis; Outer University of Science and Technology class; Surgical instruments, device or method (19/02) are used for protective package or the covering of utensil or apparatus.
(2) background technology:
Along with the extensive use of less invasive techniques in medical circle, the operation of increasing deep is arranged now by replacements such as peritoneoscope, endoscope, laser beams, but still have many body surface operations, need direct percutaneous to cut diagnosis and treatment.But at present along with medical service quality improves gradually, the effect of operation not only desired value own improves, and beautifying property of the wound surface requirement that the patient performs the operation to body surface increases day by day.And the quality of wound healing is directly connected to size and the aesthetic property of local cicatrix in the future.And among the influence factor of wound healing, first step is whether relevant smoothly with operative doctor feed luck cutter, can't accurately grasp level or angle during as feed, be prone in the otch and turn over, involutory level disorder, increasing subcutaneous tissue wound or factor such as hemorrhage, all is one of principal element that causes in postoperative body surface cicatrix.Other has the plastic surgery operations in the medical domain, many art formulas that require bilateral to equate is arranged, such as the excision amount of the unnecessary tissue of bilateral, the excision angle of the bilateral wing of nose, the thickness adjustment of bilateral lip etc., in the less zone of subrange, a bit deviation can cause postoperative significantly asymmetric.But before art, design under the rigorous situation, the asymmetric observation mainly from the angle of feed and the degree of depth according to the author of this type of operation failed precise control, though be along the operation of the design lines of symmetry and caused operator, postoperative bilateral difference on effect finally still appears.
The goal of the invention of patent of the present invention is for to controlling a kind of device that causes because of patient's personal error at present, be placed in the blade head, can make blade along fixing angle and degree of depth operation in use, operation is carried out in correct and symmetrical level at the very start, avoided hemorrhage chance to increase and the involutory disorder of level one step of in the step of prevention of scar, having accomplished fluently most critical.And in practical operation, cut micromicro to accomplish without any letup, avoided cutting repeatedly back and forth skin and tissue.
(3) summary of the invention
1, summary of the invention: apparatus of the present invention are a kind of control scalpel degree of depth pitch devices, be used for to cut skin or when organizing depth of cut and the gradient of control knife blade use.Described device is made up of pad and draw-in groove and valve rubber; Pad and draw-in groove are one, are made by hard transparent PVC sheet integral body, and valve rubber is made by the rubber silver.Draw-in groove is long fan-shaped laminar body, and fan-shaped radius is 10mm, and angle is 60 degree, and thickness is 1.2--1.5mm; There is radial gray line the centre, and every gray line interval angle is 10 degree.Fan-shaped central part is the gasket construction place, and pad is in device bottom, is thin flat rectangular-shaped long 4mm, and wide 2.5mm, thickness are 1.2--1.5mm.Valve rubber is that common soft rubber shred constitutes, and thickness is 0.7--1mm, and wide is 3-4mm, and long is 10mm.
2, the purpose of patent of the present invention mainly is achieved by following technical proposals: the thickness that the hard PVC material is made is the transparent sheet of 1.2mm-1.5mm, the upper end is up fan-shaped of arc, fan-shaped radius is 10mm, and angle is 60 degree, and thickness is 1.2-1.5mm; There is radial gray line the centre, and every gray line interval angle is 10 degree.Fan-shaped circle centre position extends into the horizontal sheet shape towards both sides, this thin slice is thin flat rectangular-shaped long 4mm, and wide 2.5mm, thickness are 1.2--1.5mm.Valve rubber is made by the rubber silver.Valve rubber is that common soft rubber shred constitutes, and thickness is 0.7--1mm, and wide is 3-4mm, and long is 10mm.Will enter the angle of skin and draft the degree of depth according to blade during use, cut off along the gray line that meets use angle with shears, the degree of depth formula of cutting off is as follows: advance the degree of depth that the draw-in groove position of the skin degree of depth=blade is cut to the vertical dimension-draw-in groove between the skin.Then valve rubber is tauted at draw-in groove and blade contact position place and places on the knife back head, the crack that again draw-in groove is cut is aimed at the valve rubber card and is inserted on the knife back head, knows that this crack degree of depth is all expired by the blade card.When holding a sword in one's hand, operator thumb and middle finger control handle of a knife, forefinger is pushed down the top of the fan-shaped arc of control device, can cut relievedly.
Therefore the present invention has following advantage:
1) this device can provide a kind of degree of depth and pitch devices of controlling the scalpel feed easily, can prevent from causing feed gradient and the inconsistent inaccurate device of the degree of depth because of patient's personal error.According to the different degree of depth and angle draw-in groove is placed in the blade head during use, in use the both sides pad will be with the skin that will cut angled and distance, just can make blade along fixing angle and degree of depth operation, operation is carried out in correct and symmetrical level at the very start.
2) owing to cut the level unanimity, avoided hemorrhage chance to increase and the involutory disorder of level one step of in the step of prevention of scar, having accomplished fluently most critical.And in practical operation, cut micromicro to accomplish without any letup, avoided cutting repeatedly back and forth skin and tissue.
