Description
Technical Field
The utility model relates to an intracranial hematoma treatment field specifically is an intracranial hematoma location piercing depth.
Background
Minimally invasive puncture is a good method for dealing with intracranial hematomas, but there are several problems that need to be improved: 1. the accuracy of puncture, especially hematoma is not very big, and is in thin and long spindle shape, and puncture must be carried out along the long axis of hematoma; 2. the whole operation is simple, quick and easy to master; 3. expensive equipment is not needed, and the method is easy to popularize in primary hospitals.
At present, a plurality of positioning methods exist, some methods are printed by means of a stereotaxic apparatus or 3d, although the puncture precision is high, the method is not convenient enough in the critical moment of capturing seconds in minutes. When stereotactic puncture is adopted, the operation is found to be more complicated and time-consuming, and particularly, the patient is restless and does not cooperate, so that the operation is difficult, and even the anaesthetist needs to perform anaesthesia intubation cooperation in a CT (computed tomography) room. And 3d printing needs a 3d printer, so that the method is not easy to popularize.
SUMMERY OF THE UTILITY MODEL
An object of the embodiment of the utility model is to provide an intracranial hematoma location piercing depth to solve the problem that provides among the above-mentioned background art.
In order to achieve the above object, the embodiment of the present invention provides the following technical solutions:

The straight line formed by the intersection of the two planes with the largest or nearly largest hematoma area and perpendicular or nearly perpendicular to each other is the puncture path. The process is conventionally determined by three-dimensional software in a CT room, and the specific method is as follows: generally, there are two types, one is approximately forward and backward and the other is approximately left and right, according to the trend of the long axis of hematoma. For the front and back trend of the long axis, a transverse plane and a sagittal plane are taken, the angles of the transverse plane and the sagittal plane are adjusted in an inclined mode through software, the areas of hematomas on the two planes are found to be close to the maximum, and the intersecting line of the two planes is the long axis of the hematoma. For hematoma with left and right long axis, we take the same method for the transverse section and the coronal section. Finally, the puncture depth is determined. If an ideal puncture path is thought to be a straight line, it crosses the long axis of the hematoma and has two points of intersection with the surface of the skull, one of the two points of intersection, which is closer to the cortex, can be used as our puncture point, and the other one is the target point. Then measuring their relative distances to the reference objects such as the upper and lower edges of the orbit, the upper edge of the external auditory meatus, the occipital protuberance, the middle line of the skull and the like on a computer, marking the surface of the scalp, if necessary, sticking the marker, rechecking the CT, and correcting the position of the marker. The working process of the product is as follows: the conventional disinfection drape is used for cutting a scalp at a puncture point, drilling a skull, opening a dura mater, taking a positioning instrument by an assistant, fixing the inner side end of a movable rod on a target point, taking a drainage tube by an operator to insert a guide pin, inserting the drainage tube into a brain along a steel tube at the tail end of a vertical rod, wherein the insertion depth reaches the tail end of hematoma as far as possible, and as long axes of the two steel tubes are superposed with the long axis of the movable rod, the path of the drainage tube points to the target point strictly according to the preset puncture point, and a straight line principle is determined according to 2 points, the path of the drainage tube is an ideal puncture path, and the puncture depth can be accurately controlled by scales.
As a further scheme of the embodiment of the utility model: the number of the vertical rods is three, the three vertical rods comprise a first vertical rod, a second vertical rod and a third vertical rod, the puncture requirement is met, and the cost performance is high.
As a further scheme of the embodiment of the utility model: the fastener adopts the nut, and the market is easily purchased, and is with low costs, excellent in use effect.

As a further scheme of the embodiment of the utility model: the fastener and the steel pipe are fixed on the vertical rod in a welding mode, the connection firmness is good, and the processing is convenient.
As a further scheme of the embodiment of the utility model: the cross section of the side wall of the steel tube is c-shaped, so that the drainage tube is convenient to take out.
Compared with the prior art, the utility model discloses the beneficial effect of embodiment is:
the product has reasonable design, simplifies the puncture path planning into finding two points on the puncture path, namely a puncture point and a target point, can be transferred and marked on the scalp by setting the two points on a computer and measuring the relative distance between the two points and a definite bony mark, and basically, one doctor can complete the operation and can complete the operation at the bedside in emergency;
the product has simple positioning principle and few links, and the distance between a target point and a puncture point is two or three times longer than that between hematoma and the puncture point, so that the error of the puncture angle is reduced in the same proportion at the hematoma part, the puncture precision is very high, and some thalamus hematomas with smaller volume can be punctured accurately;
the product has a simple structure, only one part which moves linearly along the rotation of the fastener is usually a threaded screw, and the other parts are fixed parts, so that the chance of generating errors is reduced;
the steel tube in the product is a circular tube with a c-shaped cross section, the lengths of the two steel tubes are longer, and the passing direction of the drainage tube between the two steel tubes can be ensured; the side wall of the steel tube is sawed, and after the drainage tube is successfully punctured, the steel needle in the drainage tube is pulled out (because the drainage tube is made of silica gel and is very soft, the steel needle is required to be inserted during puncturing), so that the drainage tube can be taken out from the side wall opening without withdrawing the position finder from the tail part of the drainage tube, and the operation is simpler and more convenient.
