Abstract
The utility model relates to an auxiliary utensil for an operation, in particular to a measuring instrument for a brain minimally invasive surgery. The measuring instrument for the brain minimally invasive surgery solves the problem that an operation result is influenced by inaccurate control of a placing angle of a drainage tube in the existing cerebral hemorrhage minimally invasive surgery. The measuring instrument for the brain minimally invasive surgery comprises a base. A locating support is fixed on the base, a locating pin is arranged on the locating support, and an arc angle scale arranged on the locating support rotates around the locating pin. A gravity vertical chain is hung at the circle center of the angel scale, and a gravity indicating cone is connected with the end end of the gravity vertical chain. The base is horizontal or bent, a level gauge is arranged at the base, and the angle scale is in a hollow fence structure. The gravity vertical chain and the gravity vertical cone are placed inside the angle scale, and a guide groove is arranged on the angle scale along the profile of the linear portions of the angle scale. The measuring instrument for the brain minimally invasive surgery is simple in structure, ingenuous in design and convenient to operate. The placing angle of the drainage tube can be controlled accurately with the measuring instrument for the brain minimally invasive surgery to achieve the aim of accurately eliminating hematomas at two poles so as to ensure the drainage and eliminating effect of the cerebral hemorrhage minimally invasive surgery.
Description
Technical field
The present invention relates to a kind of surgery assistor tool, be specially a kind of cranium brain invasive surgery and estimate instrument.
Background technology
Known, the cerebral hemorrhage outward appearance causes its form often for oval because neural projection fibers traveling concerns, minimizes for reaching cerebral hemorrhage minimum traumatic removing art wound/benefit rate of exchange, must accomplish that on cranium brain entity a hole multi-angle is removed, the drain design.In the middle of practical operation, usually first retouch and after CTA checks through CT is flat, selecting to avoid larger blood vessel place under the CT guiding directly locates, rear row sphenotresia drainage, after having bored the hole, the position adjustment of drainage tube is very crucial, during 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, to control for the angle of drainage tube and there is no better utensil and assist and finish, this effect of understanding performing the operation affects.
Summary of the invention
The present invention still can not accurately control for the angle of drainage tube in order to solve in the existing cerebral hemorrhage minimum traumatic art, then affects the problem of surgical effect, provides a kind of cranium brain invasive surgery to estimate instrument.
The present invention adopts following technical scheme to realize: cranium brain invasive surgery is estimated instrument, comprise the base that contacts with skull, vertically be fixed with locating support on the base, locating support is provided with alignment pin and is movably arranged on the locating support and the semicircle angle scale that can rotate take alignment pin as the center of circle by alignment pin, the circle centre position of angle scale is hung with the gravity vertical chain, and gravity vertical chain end is connected with the gravity indication cone of orientation angle dial scale value.
In order further to optimize the structure of this instrument, improve its function, the present invention has also carried out following structural design:
Horizontal or the bending of described base, base is provided with level indicator, and sweeping base can be convenient to contact, locate with cranium brain.The effect of level indicator is to guarantee locating support perpendicular to the cranium brain, guarantees that then the accuracy of reading of angle scale is errorless;
Described angle scale is hollow fence type structure, and gravity vertical chain and gravity indication cone are positioned at angle scale, and the angle scale weight of this version is low weight, convenient operation, and in addition, gravity vertical chain and gravity indication cone can not affect normal operation technique yet; Be provided with gathering sill on the described angle scale and along the side section of its straightway, when drainage tube inserts or extracts the cranium brain, can operate along gathering sill.
Compared with prior art, the present invention is simple in structure, design is ingenious, easy and simple to handle, after the intracranial hematoma scope is positioned, can adopt this to estimate the insertion angle that instrument is accurately controlled drainage tube, reach the purpose of accurate removing the two poles of the earth hematoma, thereby guaranteed the effect of cerebral hemorrhage minimum traumatic operation.

The specific embodiment
Cranium brain invasive surgery is estimated instrument, as shown in Figure 1, comprise the base 1 that contacts with skull, vertically be fixed with locating support 2 on the base, locating support is provided with alignment pin 3 and is movably arranged on the locating support 2 and the semicircle angle scale 4 that can rotate take alignment pin 3 as the center of circle by alignment pin, angle scale is similar to known protractor, be provided with the scale value of 0 ~ 180 degree along its curved section one side, the circle centre position of angle scale 4 is hung with gravity vertical chain 5, gravity vertical chain 5 ends are connected with the gravity indication cone 6 of orientation angle dial scale value, and gravity vertical chain and gravity indication cone are vertically downward because of himself gravity on angle scale all the time.Be provided with gathering sill 8 on the angle scale 4 and along the side section of its straightway, the gathering sill transverse shape is U-shaped.
As shown in Figure 1, 2, base 1 bending horizontal or that match with the cranium brain radian, base is provided with level indicator 7; Angle scale 4 is hollow fence type structure, and gravity vertical chain 5 and gravity indication cone 6 are positioned at angle scale 4.
During use, base is placed horizontally at cranium brain tapping, then the angle scale on the rotational positioning support, so that the indication of gravity vertical chain and gravity have a meagre knowledge of to drainage tube should oblique insertion angle value (this angle value and insertion depth are to set after being checked by CT scan and CTA, remove clean with the hematocele of guaranteeing hematoma the two poles of the earth, can not damage normal cerebral tissue again), the drainage tube that will include seal wire this moment inserts in the minimally invasive hole along the gathering sill on the angle scale straightway side section and gets final product, if make drainage tube along in the different directions patchhole, accurately arrive Hemorrhagic location, can be by the angle value of having set in advance and insertion depth, by realizing to different directions angle of rotation scale.
