Abstract

The invention provides a craniocerebral minimally-invasive puncture device with a laser positioning function, and belongs to the field of medical instruments special for craniocerebral minimally-invasive puncture. The craniocerebral minimally-invasive puncture device is provided with an electric drill and a puncture needle installed on the head of the electric drill, a shell of the electric drill is provided with an installation frame, and an arc-shaped hole is formed in the concentric circle of the installation frame; a first straight line laser is fixedly connected with the installation frame through a first connecting rod, a second straight line laser is slidably connected to the arc-shaped hole through a second connecting rod, a straight line ray emitted by the first straight line laser interests with a straight line ray emitted by the second straight line laser, and the intersection point of the two straight line rays coincides with the circle center of the puncture needle. By using the device, the accuracy rate of craniocerebral minimally-invasive puncture operation can be increased, and the operation difficulty and the puncture risk can be reduced.

Description

Skull micro wound sting device with laser positioning

Technical field

The present invention relates to skull micro wound and puncture special medical device, specifically a kind of skull micro wound sting device with laser positioning.

Background technology

In the past in skull micro wound puncture procedure process, patient's intracranial lesion position is carried out puncture for treating by the sting device that doctor uses, sting device is made up of medical electric drill and the puncture needle being arranged on electric drill head, patients head is after CT localised puncture point, doctor is in the head setting-out of patient, according to setting-out situation, with the naked eye position, hand-held sting device carries out puncture for treating, owing to the vision power of people has certain error, and the site of puncture of skull mostly is arc, so when operation, the syringe needle of puncture needle is easily sliding inclined, puncture glances off, cause that the accuracy rate punctured is low, add puncture risks, in piercing process, keep puncture needle vertical relative to skull, the operating technology of doctor is required significantly high, even if carrying out radiography puncture on large-scale CT machine, its accuracy rate is still not high, and the aseptic condition of CT Room is poor, add the risk of patient's traumatic infection.

Summary of the invention

It is an object of the invention to provide a kind of skull micro wound sting device with laser positioning, the accuracy rate of skull micro wound puncture procedure can be improved, reduce operation easier and puncture risks.

The technical scheme is that the skull micro wound sting device with laser positioning, there is electric drill and be contained in the puncture needle of electric drill head, it is characterized in that: equipped with installing rack on the shell of electric drill, the concentric circular of installing rack is provided with arcuate socket, one word line laser device A is connected with installing rack by first connecting rod, one word line laser device B is slidably connected in arcuate socket by second connecting rod, a word ray that one word line laser device A sends and the word ray intersection that a word line laser device B sends, the intersection point of two 1 word rays overlaps with the center of circle of puncture needle.

The invention have the advantage that patients head is after CT localised puncture point, doctor is in the head setting-out of patient, determine point of puncture position, two line of reference with point of puncture for intersection point or summit are drawn patients head, record the angle angle of two line of reference, by adjusting the position of a word line laser device B, the word ray intersection angle that two-laser projects is made to be consistent with line of reference angle angle; When carrying out puncture procedure, hand-held sting device, make two 1 word rays overlapping with two line of reference all the time, can guarantee that puncture needle is advanced by predetermined puncture direction, can find if any deviation in time and correct, the accuracy rate punctured in the broken suction puncture procedure of head Wicresoft hematoma can be improved, reduce operation easier and puncture risks.

Fig. 2 is the main TV structure schematic diagram of the skull micro wound sting device with laser positioning of the present invention.

The head end of 1 one word line laser device B, the shell of 2 electric drills, 3 electric drill heads, 4 puncture needles, the center of circle line of 5 puncture needles, the center of circle of 6 puncture needles, 7 crossing angles, 8 one word rays, 9 arcuate sockets, 10 cylinders, 11 installing racks, 12 bolts, 13 angle index grooves, 14 second connecting rods, 15 first connecting rods, 16 telescopic ends, 17 1 word line laser device A, 18 bolts in figure.

Detailed description of the invention

Skull micro wound sting device with laser positioning, there is electric drill and be contained in the puncture needle 4 of electric drill head 3, on the shell of electric drill, 2 equipped with installing rack 11, the concentric circular of installing rack is provided with arcuate socket 9, one word line laser device A17 is connected with installing rack by first connecting rod 15, one word line laser device B1 is slidably connected in arcuate socket by second connecting rod 14, one word laser instrument B is connected to the shell of electric drill on the center of circle 6 of puncture needle for axis rotation by installing rack, a word ray 8 that one word line laser device A sends and the word ray intersection that a word line laser device B sends, the intersection point of two 1 word rays overlaps with the center of circle of puncture needle, namely two 1 word line laser device project two crossing word rays along the axial of puncture needle, article two, the intersection point of a word ray is positioned on the center of circle line 5 of puncture needle, article two, a word ray is perpendicular to the center of circle line of puncture needle along the circumferencial direction of puncture needle, during use, crossing angle 7 angle of two 1 word rays is with the angle angle-determining of two line of reference, a described word line laser device is commercially available prod, it is possible to project the hot spot of a wordline shape, and a word ray of its projection can arbitrarily be finely tuned, and reaches best result of use, and described annular slab thickness is 1～3cm, it is ensured that the intensity of annular slab.

The shell afterbody of described electric drill is cylinder 10, cylindrical axle center is coaxial with the axle center of puncture needle, described installing rack is annular slab, the inner ring surface of annular slab and the socket of described cylindrical periphery, namely annular slab is with the spacing shell afterbody being slidably connected to electric drill of cylinder, annular slab is connected with this cylinder by jackscrew, described arcuate socket is located on the concentric circular of annular slab, described second connecting rod is arranged in arcuate socket by bolt 12, this bolt this arcuate socket of traverse, the bottom surface of the head end 18 of bolt crimps with the bottom surface activity of annular slab, the rod end periphery of bolt and the wall surface of the hole of arcuate socket are slidably connected, the bottom surface of second connecting rod crimps with the end face activity of annular slab, the bottom surface of second connecting rod one end is provided with the screw corresponding with bolt, bolt is threadeded with second connecting rod by this screw, the advantage of said structure is: the annular slab supporting two 1 word line laser device is arranged on the cylindrical electric drill shell afterbody with puncture needle concentric, the circumferential direction of annular slab is vertical and puncture needle axle center, make two 1 word line laser device accurate positionings, make installing rack simple in construction, easy to assembly, the position of a word ray of two 1 word line laser device projections can be adjusted better more easily, angle, described arcuate socket, provided peripherally with angle index groove 13, can conveniently regulate the angle of projection one word ray, the link of described first, second connecting rod and laser instrument is telescopic end 16, and advantage is to regulate the position of a word ray at three-dimensional.
