Abstract
A craniocerebral puncture director mainly provides direction indication for craniocerebral minimally invasive surgery drill skull retained needle process. The concrete structure is that: an elastic sheet metal is made into more than half circle; three oriented benchmarks are arranged on the sheet metal. In use, the director is put on the special position of patient's head, an acupuncture apparatus is kept overlapped with the benchmarks when inserting needle, which can accurately reach hemorrhage target, sucking out the blood in brain.
Description
Technical field
The cranium brain Minimally Invasive Surgery that this utility model belongs to medical domain bores the cranium device, mainly is meant cranium brain puncture finder.
Background technology
Treatment cerebral hemorrhage patient generally need be by the brain puncture method with the congestion sucking-off of bleeding part, so, make needle set accurately arrive target spot, be the key that improves success rate of operation.Technology in the past is to draw graticule according to brain CT image at head, or by the two point method orienting device, determines puncture position and inserting needle direction, and this method is inaccurate, and complicated operation is lost time, and causes operative failure easily.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of cranium brain puncture finder for the deficiency that solves existing cranium brain puncture technique existence.
The purpose of this utility model can reach by the following technical programs:
This finder comprises C shape ring (1) and directed mark post (2), and directed mark post is installed on the C shape ring.
The purpose of this utility model can also reach by the following technical programs:
Three directed mark posts are along C shape ring surface setting and vertical with the limit of ring, and the line of three directed mark posts is triangular in shape.
The utlity model has following advantage:
1, accurately directed, the success rate height.
2, device is simple, and is easy to operate, quick.
Description of drawings
Fig. 1 is a front view of the present utility model, and wherein (1) C shape is encircled, (2) directed mark post.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the three-dimensional view of Fig. 1.
Fig. 4 is the user mode figure of this utility model at people's head, wherein (3) people's head.
The specific embodiment
Getting one section has the elastic sheet metal of being with of certain width, and sheet metal is curved more than half garden shape, presents C shape ring, and this ring is represented a plane.Along C shape ring three mark posts that play to the position effect are installed vertically, mark post inserts and is installed in the groove of the clamp on the ring, and clamp can slide on sheet metal, and mark post can direction of rotation on clamp.
This finder is to put pin process provider to indication for cranium brain Minimally Invasive Surgery bores cranium, need not to draw graticule at head, under CT or by CT sheet orientation, the guide needle prodigiosin enough accurately arrives target spot, improves success rate of operation.
The use of this finder (as shown in Figure 4) is that the people lies on one's side, finder is worn over head, with the intersection point of C shape ring with the mark post of its two-end part, place on the front and back sagittal line of the maximum hemorrhage aspect of CT, and be the axle center with these 2, adjust the position of C shape ring, the mark post that makes two intersection point places on this CT aspect, fixation of C shape ring position.The 3rd mark post places C shape ring top.If it is vertical with the CT sagittal line to set the inserting needle direction, then can reach predetermined target spot as long as keep needle set and C shape to encircle the end with top mark post overlapping (or parallel) during inserting needle.If the inserting needle direction is not vertical with sagittal plane, and at an angle, the angle that then only needs to adjust the top mark post equates with the mensuration angle, and the direction unanimity by this mark post inserting needle, can reach the precalculated position.Its principle is 1, and two vertical lines at grade can be overlapping; 2, two parallel surfaces at grade, if the ray in the same way on two parallel surfaces equates that with the angle of bottom surface then these two rays can be overlapping.
Claims (2)
1, a kind of cranium brain puncture finder is characterized in that C shape ring (1) is provided with directed mark post (2).
2, finder according to claim 1 is characterized in that three directed mark posts along C shape ring surface setting and vertical with the limit of ring, and the line of three directed mark posts is triangular in shape.
