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

Cranium brain Wicresoft art is estimated appearance

Technical field

The present invention relates to a kind of operation auxiliary implement, be specially a kind of cranium brain Wicresoft art and estimate appearance.

Background technology

Known, the cerebral hemorrhage outward appearance causes its form often for oval because of 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 earlier through CT flat retouch and the CTA inspection after, the CT guiding down selection avoid bigger blood vessel place and directly locate; Back row sphenotresia drainage; After having bored the hole, the adjustment of the position of drainage tube is very crucial, especially when drainage tube is placed at the two poles of the earth of ellipse; Angle is controlled the most key, otherwise can cause unnecessary normal cerebral tissue's damage.At present, in the cerebral hemorrhage minimum traumatic operation, though very accurate for the location of hematoma, still do not have better utensil for the angle control of drainage tube and assist completion, this can affect to the effect of operation.

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, influences the problem of surgical effect then, provides a kind of cranium brain Wicresoft art to estimate appearance.

The present invention adopts following technical scheme to realize: cranium brain Wicresoft art is estimated appearance; Comprise the base that contacts with skull; Vertical fixing has locating support on the base; Locating support is provided with alignment pin and is movably arranged on the locating support and can is the semicircle angle scale that rotate in the center of circle with the alignment pin through alignment pin, and 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 awl 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:

Described base bending horizontal or that match with the cranium brain radian, 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 awl are positioned at angle scale, and the angle scale weight of this version is low weight, is convenient to operation, and in addition, gravity vertical chain and gravity indication awl can not influence 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 appearance 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.

Description of drawings

Fig. 1 is one of structural representation of the present invention;

Fig. 2 is two of a structural representation of the present invention;

Fig. 3 is the left view of angle scale among Fig. 1;

Among the figure: the 1-base; The 2-locating support; The 3-alignment pin; The 4-angle scale; 5-gravity vertical chain; 6-gravity indication awl; The 7-level indicator; The 8-gathering sill.

The specific embodiment

Cranium brain Wicresoft art is estimated appearance; As shown in Figure 1, comprise the base 1 that contacts with skull, vertical fixing has locating support 2 on the base; Locating support is provided with alignment pin 3 and is movably arranged on the locating support 2 and can is the semicircle angle scale 4 that rotate in the center of circle with alignment pin 3 through alignment pin; Angle scale is similar to known protractor, along its curved section one side be provided with 0 ~ 180 the degree scale value, 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 awl 6 of orientation angle dial scale value, and gravity vertical chain and gravity indication awl 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 the U type.

Like Fig. 1, shown in 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 awl 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; Make 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 by CT scan and CTA inspection; Clean to guarantee the dipolar hematocele removing of hematoma, 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 the hematoma position, can be by angle value of having set in advance and insertion depth, through realizing to different directions angle of rotation scale.
