Abstract

The invention relates to a surgery assistant device, in particular to a degree measuring instrument for a craniocerebral keyhole surgery, which solves the problems of incapability of precisely controlling a drainage tube placing angle and influences on surgery effects in the conventional cerebral hemorrhage keyhole surgery. The degree measuring instrument comprises a pedestal, wherein a positioning bracket is fixed on the pedestal; a positioning pin is arranged on the positioning bracket; a semicircular angle scale is arranged on the positioning bracket and can rotate by taking the positioning pin as a circle center; a gravity hammer chain is hung at a circle center of the angle scale; the tail end of the gravity hammer chain is connected with a gravity indication cone; the pedestal is horizontal or has a curved shape which is coincided with the craniocerebral radian of a human body; a level gauge is arranged on the pedestal; the angle scale has a hollow fence type structure; the gravity hammer chain and the gravity indication cone are positioned in the angle scale; and a guide groove is formed on the angle scale along a side cross section of a straight-line segment of the angle scale. The degree measuring instrument has a simple structure and is skillful in design and easy and convenient to operate, the inserting angle of a drainage tube is precisely controlled by using the degree measuring instrument, the aim of accurately cleaning bipolar hematoma is fulfilled, and the effects of draining and cleaning of the craniocerebral keyhole surgery are ensured.

Description

Skull micro wound art estimates instrument

Technical field

The present invention relates to a kind of surgery assistor tool, be specially a kind of skull micro wound art and estimate instrument.

Background technology

Known, cerebral hemorrhage outward appearance, because of Nervons projection fiber traveling relation, causes its form often for oval, minimizing, cranium brain entity must be accomplished a hole multi-angle is removed, drain design for reaching the wound/benefit rate of exchange of cerebral hemorrhage minimum traumatic removing art.In the middle of practical operation, usual elder generation to retouch and after CTA checks through CT is flat, under CT guides, select to avoid larger blood vessel place directly locate, rear row sphenotresia drainage, after having bored hole, the adjustment of the position of drainage tube is very crucial, time especially to the two poles of the earth placing drainage of ellipse, angle is controlled the most key, otherwise can cause unnecessary normal cerebral tissue's damage.At present, in cerebral hemorrhage minimum traumatic operation, although very accurate for the location of hematoma, the angle for drainage tube is controlled and be there is no better utensil to have assisted, and this can affect to the effect of operation.

Summary of the invention

The present invention still can not accurately control in order to the angle solved for drainage tube in existing cerebral hemorrhage minimum traumatic art, then affects the problem of surgical effect, provides a kind of skull micro wound art to estimate instrument.

The present invention adopts following technical scheme to realize: skull micro wound art estimates instrument, comprise the base contacted with skull, base is vertically fixed with locating support, locating support is provided with alignment pin and is movably arranged on locating support by alignment pin and can is the semicircle angle scale that the center of circle is rotated with alignment pin, the circle centre position of angle scale is hung with gravity vertical chain, and gravity vertical chain end is connected with the gravity instruction cone of orientation angle dial scale value.

In order to optimize the structure of this instrument further, improve its function, the present invention has also carried out following structural design:

Horizontal or the bending matched with cranium brain radian of described base, base is provided with level indicator, and sweeping base can be convenient to contact with cranium brain, locate.The effect of level indicator is to ensure that locating support is perpendicular to cranium brain, guarantees that the accuracy of reading of angle scale is errorless then;

Described angle scale is hollow fence type structure, and gravity vertical chain and gravity instruction cone are positioned at angle scale, and the angle scale weight ratio of this version is comparatively light, convenient operation, and in addition, gravity vertical chain and gravity instruction cone also can not affect normal operation technique; Be provided with gathering sill on described angle scale and along the side section of its straightway, insert at drainage tube or when extracting cranium brain, can operate along gathering sill.

Compared with prior art, structure of the present invention is simple, it is ingenious, easy and simple to handle to design, after intracranial hematoma scope is positioned, and this can be adopted to estimate the insertion angle that drainage tube accurately controlled by instrument, reach the object accurately removing the two poles of the earth hematoma, thus ensure that the effect that cerebral hemorrhage minimum traumatic is performed the operation.

Detailed description of the invention

Skull micro wound art estimates instrument, as shown in Figure 1, comprise the base 1 contacted with skull, base is vertically fixed with locating support 2, locating support is provided with alignment pin 3 and is movably arranged on locating support 2 and the semicircle angle scale 4 that can rotate for the center of circle with alignment pin 3 by alignment pin, angle scale is similar to known protractor, the scale value of 0 ~ 180 degree is provided with along its curved section side, the circle centre position of angle scale 4 is hung with gravity vertical chain 5, gravity vertical chain 5 end is connected with the gravity instruction cone 6 of orientation angle dial scale value, gravity vertical chain and gravity instruction are bored on angle scale because himself gravity is vertically downward all the time.Be provided with gathering sill 8 on angle scale 4 and along the side section of its straightway, gathering sill transverse shape is U-shaped.

As shown in Figure 1, 2, the horizontal or bending matched with cranium brain radian of base 1, base is provided with level indicator 7; Angle scale 4 is hollow fence type structure, and gravity vertical chain 5 and gravity instruction cone 6 are positioned at angle scale 4.

During use, base is placed horizontally at cranium brain tapping, then the angle scale on rotational positioning support, make gravity vertical chain and gravity instruction have a meagre knowledge of to drainage tube should oblique insertion angle value (this angle value and insertion depth be checked by CT scan and CTA after set by, to guarantee that the hematocele at hematoma the two poles of the earth is removed clean, normal cerebral tissue can not be damaged again), now the drainage tube including seal wire is inserted in minimally invasive hole along the gathering sill on angle scale straightway side section, if make drainage tube along in different directions patchhole, accurate arrival Hemorrhagic location, can by the angle value set in advance and insertion depth, by realizing to different directions angle of rotation scale.
