Abstract

The utility model relates to an intracranial hematoma puncture positioning instrument and belongs to the field of medical instruments. The intracranial hematoma puncture positioning instrument comprises a right-angle caliper 1 and a semicircular protractor instrument 2 and is characterized in that a rotating shaft 3 is arranged at the right-angle part of the right-angle caliper 1; the right-angle caliper 1 is connected with the semicircular protractor instrument 2 together by the rotating shaft 3; and graduated scales 4 are formed in the lateral surface of the right-angle caliper 1; and minimum graduated scales are 1 mm. The intracranial hematoma puncture positioning instrument disclosed by the utility model has the advantages of simple structure, convenience in use, accuracy in positioning, safety and reliability; and the intracranial hematoma puncture positioning instrument can be used for measuring the size of intracranial hematoma and the distance between the intracranial hematoma and the surface of skull and for measuring an included angle between the intracranial hematoma and a central sagittal line of craniocerebrum and is an ideal intracranial hematoma puncture positioning instrument.

Description

The intracranial hematoma puncture 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, accurate positioning, safe and reliable intracranial hematoma puncture position finder.

Background technology: the intracranial hematoma puncture art is a basic skill operation in the neurocranial surgery clinical position, before the patient is carried out intracranial hematoma puncture, needs at first to confirm point of puncture and puncture angle; And paracentesis depth, at present, clinical method commonly used is; After patient's cranium brain CT slice, thin piece comes out; Size and the hematoma of at first measuring hematoma with rule are estimated the makeup of puncture then to the distance of skull surface, and this method is slow; And be difficult to accurate location, thereby cause 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; Accurate positioning, safe and reliable intracranial hematoma puncture position finder.

For realizing above-mentioned purpose; This utility model has been taked following technical scheme: this intracranial hematoma puncture position finder; Be 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, and rotating shaft connects together the right angle slide calliper rule with the semicircle angulometer; The side of right angle slide calliper rule is provided with scale, and minimum scale is 1mm.

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 a kind of ideal intracranial hematoma puncture 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, 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 side of right angle slide calliper rule 1 is provided with scale 4, and minimum scale is 1mm.

When using this utility model, measure size and the hematoma of intracranial hematoma distance with the scale on the right angle slide calliper rule 14 earlier, measure the angle that intracranial hematoma and cranium brain hit exactly sagittal line with semicircle angulometer 2 then and get final product to skull surface.
