Abstract

The invention discloses a portable positioning device for intracerebral cathetering in neurosurgery. In cerebral hemorrhage or other brain diseases, the surgery application range of intracerebral cathetering is wide. Most of diseases of people suffering from the brain diseases are sudden onset; in the emergency surgery, the lesions are roughly positioned according to a preoperative computed tomography (CT) film under the general condition, free-hand puncturing is performed, and the cathetering path, direction and depth cannot be accurately controlled. The positioning device can find the level reached by cathetering through CT according to the principle that distances between all points on a spherical surface and a sphere center are equal, and the position of a catheter to be placed in the brain is adjusted to the angle that the sphere center of the positioning device and the puncturing direction can be changed front and back and left and right, and the cathetering depth is the radius of the sphere, so that the device can accurately reach the puncturing point. The positioning device is convenient to operate in intracerebral cathetering surgery such as intracranial hematoma puncturing, ventricular puncturing, and brain abscess puncturing, and can position the lesions accurately, and improve the achievement ratio of surgery. The portable positioning device is convenient to operate and practical in the encephalic cathetering in brain surgery and has wide popularization and application prospect.

Description

Portable brain built-in pipe localizer

Technical field

The present invention is the location instrument when belonging to the operation of department of cerebral surgery brain built-in pipe, and is convenient when the brain built-in pipe is performed the operation, practical, accurate.Belong to medical instruments field.

Background technology

Brain built-in pipe art is department of cerebral surgery modus operandi commonly used, is usually used in cerebral hemorrhage, ventricular hemorrhage, the diseases such as brain abscess.This type of patient is generally the emergency case, and the state of an illness is attached most importance to, and clinically carries out coarse localization generally according to the body surface symbol of CT sheet and patient before art, free-hand puncture, and direction and the degree of depth of put canal path, putting pipe can not accurately be controlled; Especially scalp point of puncture and brain built-in pipe position be not when same CT scan aspect (such as lateral cerebral ventricle puncture), when putting pipe and need to form certain angle with skull, often put the pipe position not good enough, sometimes need according to clinical experience, repeatedly adjust puncture and intubation, so often caused unnecessary brain tissue impairment.Cause irremediable damage for patient's prognosis.For solve fast, precisely, puncture and intubation operation easily, we have developed this localizer.

At present, department of cerebral surgery is put the localization method of pipe operation clinically: 1. tricorn is put pipe: before general coronal suture, 2.5cm place's boring is opened on 2cm center line side, when putting pipe, direction is the intersection point of the line of homonymy endocanthion and bilateral external auditory meatus, puts pipe degree of depth 5-8cm, and different crowd is rule of thumb adjusted; 2. Acute Hypertensive Intracerebral Hematoma chamber paracentesis: generally when the same aspect puncture of CT scan, can determine the scalp point of puncture and put the pipe degree of depth according to CT scan, but sometimes because the boring displacement may cause puncture inaccurate; Sometimes in order to avoid intracranial critical function district, scalp point of puncture and cranium built-in pipe position be not when same CT scan plane, and when perhaps putting pipe and needing certain angle, puncture and intubation adds under experience in measurement often and carries out, the puncture and intubation accuracy is guarantee not, and effect is not good enough; 3. brain stereotaxic localized puncture: this operation needs first wear the headstock before art, puncture and intubation again after the CT Room location scanning then, although location of operation is accurate, operation process is loaded down with trivial details, and the time is longer, is unwell to that sb.'s sickness becomes critical, unconsciousness, irritated patient.But major part is put the pipe patient for patients with cerebral hemorrhage clinically, and the state of an illness is critical, unconsciousness, restless, unsuitable stereo-directional puncture, and need convenient, fast and accurate localizer, this localizer has just in time solved this difficult problem, puts the pipe operation for Emergency Patients such as cerebral hemorrhages guarantee is provided.Can greatly improve success rate of operation.

Summary of the invention

(1) goal of the invention: the present invention seeks to design a kind of portable brain built-in pipe localizer, when solving cerebral hemorrhage etc. and needing the operation of emergency treatment brain built-in pipe, convenient, puncture and intubation accurately improves success rate of operation.

(2) technical scheme: portable brain built-in pipe localizer, it has the semicircular in shape centring ring, at centring ring two ends, the activity orientation chi is housed, and activity orientation chi inner termination is connected with locating clip; The activity orientation cover also is housed on centring ring simultaneously.The activity orientation chi is enclosed within centring ring and uses the dog screw fixed position.Locating clip is axially turned up along centring ring, and it is highly suitable with the activity orientation cover to turn up height.Activity orientation is sleeved on centring ring, and activity orientation puts and is shaped with two parallel puncturing holes.

This localizer points to the equidistant principle of the centre of sphere according to each point of sphere, find by CT the aspect that pipe need to arrive of putting, plan in brain is put manage the centre of sphere that localizer is adjusted in the position, but puncture direction all around angle changing, putting the pipe degree of depth is radius of sphericity, thereby can accurately arrive the point of puncture position.Localizer is bent by semi arch, slide block (with the puncture casing of different size) on the adjustable locating rod of both sides band scale and arc bow forms, the more than half circular diameters of locating rod line, puncture casing and locating rod point to the center of circle at same semi-circle plane and direction, and this plane is parallel with arc bow semi-circle plane.

The specific embodiment

As shown in Fig. 1-2, portable brain built-in pipe localizer, it has semicircular in shape centring ring 1, at centring ring 1 two ends, activity orientation chi 2 is housed, and activity orientation chi 2 inner termination are connected with locating clip 4; Activity orientation cover 3 also is housed on centring ring 1 simultaneously.Activity orientation chi 2 is enclosed within centring ring 1 and with dog screw 5 fixed positions.Locating clip 4 is axially turned up along centring ring, and it is highly suitable with activity orientation cover 3 to turn up height.Activity orientation cover 3 is sleeved on centring ring 1, and is shaped with two parallel puncturing holes on activity orientation cover 3.

Using method in the present invention's operation: as shown in Figure 3, find out puncture tube according to CT and intend position b point, measurement markers goes out a, c 2 points on scalp, according to the boring puncture position on skull.Operation CT aspect a, 2 of c can adjust, as long as by the b point.After operation is holed successfully, when putting pipe, the localizer locating rod is placed in a, c 2 points, adjust locating rod length, make the b point be positioned at the localizer centre of sphere (being a side gauge bar length+ab length=c side gauge bar length+bc length), can the up and down rotation direction take the ac point as axle in when puncture, slide block on arc bow can the left-right rotation direction, and drainage tube makes smoothly by the scalp drill hole, and putting the pipe degree of depth is arc bow radius.Puncture and successfully namely take off localizer, continue the subsequent procedures operation.
