Abstract

The utility model relates to an interventional drainage locating instrument for intracranial hematoma and belongs to the field of medical instruments. The interventional drainage locating instrument is formed by a right angular caliper 1 and a semi-circular goniasmometer 2. The interventional drainage locating instrument is characterized in that a rotary shaft 3 is arranged at a right angular position of the right angular caliper 1, the right angular caliper 1 and the semi-circular goniasmometer 2 are connected together through the rotary shaft 3, inner scales 4 are arranged on the inner side of the right angular caliper 1, the minimum scale is 1mm, outer scales 5 are arranged on the outer side of the right angular caliper 1, and the minimum scale is 5mm. The interventional drainage locating instrument is simple in structure, convenient to use, capable of measuring the size of the intracranial hematoma and distance between the hematoma and the surface of a skull, capable of measuring an included angle between the intracranial hematoma and a sagittal line in the middle of a brain, correct to locate, safe and reliable and ideal.

Description

Intracranial hematoma gets involved the drain position finder

Technical field: this utility model belongs to medical instruments field; Be particularly related to a kind of size that both can measure intracranial hematoma and hematoma distance to skull surface; Can measure the angle of intracranial hematoma and cranium brain center sagittal line again, the intracranial hematoma of accurate positioning gets involved the drain position finder.

Background technology: it is a basic skill operation in the Invasive Technology Department clinical position that intracranial hematoma gets involved drainage, before the patient being carried out intracranial hematoma intervention drain, needs the angle of at first confirming to get involved drain point and getting involved drain; And the degree of depth, at present, clinical method commonly used is; After patient's cranium brain CT slice, thin piece comes out; At first measure size and the hematoma of hematoma distance,, be converted into size and the hematoma of actual hematoma actual range to skull surface then according to the scale size of CT sheet to skull surface with rule; Estimate the makeup of puncture again; This method is slow, and is difficult to accurate location, thereby causes unnecessary loss and misery to the patient.

Summary of the invention: the purpose of this utility model is to provide a kind of size that both can measure intracranial hematoma and the hematoma distance to skull surface, can measure the angle of intracranial hematoma and cranium brain center sagittal line again, and the intracranial hematoma of accurate positioning gets involved the drain position finder.

For realizing above-mentioned purpose, this utility model has been taked following technical scheme: this intracranial hematoma gets involved the drain position finder, is made up of right angle slide calliper rule and semicircle angulometer; The place, right angle of right angle slide calliper rule is provided with rotating shaft; Rotating shaft connects together the right angle slide calliper rule with the semicircle angulometer, the medial surface of right angle slide calliper rule is provided with interior scale, and minimum scale is 1mm; The lateral surface of right angle slide calliper rule is provided with EXT scale, and minimum scale is 5mm.

This utility model, simple in structure, easy to use; Both can measure size and the hematoma of intracranial hematoma distance, can measure the angle of intracranial hematoma and cranium brain center sagittal line again, accurate positioning to skull surface; Safe and reliable, be that a kind of ideal intracranial hematoma gets involved the drain position finder.

Description of drawings: this utility model is described further below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of this utility model.

With reference to accompanying drawing 1,1, right angle slide calliper rule, 2, the semicircle angulometer, 3, rotating shaft, 4, interior scale, 5, EXT scale.

The specific embodiment: this utility model; Be made up of right angle slide calliper rule 1 and semicircle angulometer 2, the place, right angle of right angle slide calliper rule 1 is provided with rotating shaft 3, and rotating shaft 3 connects together right angle slide calliper rule 1 with semicircle angulometer 2; The medial surface of right angle slide calliper rule 1 is provided with interior scale 4; Minimum scale is 1mm, and the lateral surface of right angle slide calliper rule 1 is provided with EXT scale 5, and minimum scale is 5mm.

When using this utility model; Earlier measure size and the hematoma of intracranial hematoma distance to skull surface with the interior scale 4 on the right angle slide calliper rule 1; Contrast CT scale observation EXT scale 5 then; Read actual size and the hematoma of the intracranial hematoma actual range to skull surface, the angle that reuse semicircle angulometer 2 is measured intracranial hematoma and cranium brain center sagittal line gets final product.

Claims (1)
