Abstract
The utility model relates to the medical field, particularly to an intracranial lesion puncture aid. The intracranial lesion puncture aid comprises an arc-shaped case and a positioning channel penetrating through the arc-shaped case, wherein the included angle formed by planes of contact points of the positioning channel and the arc-shaped case is a right angle or an accurate angle, and the arc-shaped case is spherical. Compared with the prior art, the intracranial lesion puncture aid adopting the technical scheme has the benefits as follows: the puncture aid is scientific and reasonable in design and extremely high in clinic practicability; operators can find accurate puncture channels and reach needed target points accurately by the aid of the puncture aid; the puncture aid is cheap in material, convenient to operate and very easy to popularize nationwide; neurosurgeons enable puncture needles to reach intracranial target points conveniently, rapidly and accurately, and the accuracy and the curative effect of neurosurgical operations can be improved.
Description
Technical field
This utility model relates to medical field, relates in particular to a kind of intracranial lesion puncture aid.
Background technology
For the patient of hypertensive cerebral hemorrhage or intracranial mass lesion, while being expert at operation, sometimes need vertical brain surface or angled puncture, because cerebral tissue surface is a kind of cambered surface of subglobular, so be all often probably to gesticulate and puncturing.Paracentesis depth is generally in 5cm left and right simultaneously, so angle has certain difference, the position that final puncture needle arrives can differ larger distance.
The following point that puncture exists at present: when intracranial lesion puncture is expert at by current nearly all hospital, be all to rely on eye rough estimate angle, puncture.As long as this just causes angle some gap of position slightly, and through after the advancing of 5cm, the puncture needle location is just larger from impact point gap.
The stereotaxis having now can be determined puncture inserting needle road accurately.But stereotaxis is expensive, preoperatively need to go up the headstock, and then row scans with CT and MRI that stereotactic apparatus was corrected, then according to software, determine puncture path.Stereotactic apparatus is expensive, and needs certain Professional knowledge, so be difficult to popularize.For emergency operation, too time-consuming in addition.
Utility model content
The object of utility model: for a kind of device is provided, puncture angle problem when this kind of device can solve current craniocerebral operation.
In order to reach as above object, this utility model is taked following technical scheme:
An intracranial lesion puncture aid, is characterized in that, comprises arc shell, also comprises the placed channel through arc shell.
The further technical scheme of this utility model is, the plane included angle at the contact point place of described placed channel and arc shell is right angle or acute angle.
The further technical scheme of this utility model is, described arc shell is sphere.
The further technical scheme of this utility model is, described placed channel and arc shell are connected.
The further technical scheme of this utility model is that described placed channel and arc shell releasable connection have more than one locating hole on described arc shell.
The further technical scheme of this utility model is, described arc shell has two-layer, the two small one and large one and arranged concentric, the size in the hole on the two is identical.
The further technical scheme of this utility model is, described arc shell has two-layer and connects by support.
The further technical scheme of this utility model is, described placed channel is hollow cylindrical.
The further technical scheme of this utility model is, described placed channel is transparent material.
The further technical scheme of this utility model is, described placed channel is PVC material.
Adopt as above this utility model of technical scheme, with respect to prior art, have following beneficial effect: design science is reasonable, have extremely strong Clinical practicability; Puncture aid can allow operator, has puncture path accurately, reaches accurately needed impact point; Puncture aid material is cheap, easy and simple to handle, and very easily the whole nation is universal.
This utility model makes neurosurgeon can convenient, fast and accurately allow puncture needle arrive intracranial impact point, improves accuracy and the curative effect of neurosurgery.
Accompanying drawing explanation
In order to further illustrate this utility model, below in conjunction with accompanying drawing, further describe:
Fig. 1 is the plan structure schematic diagram of utility model;
Fig. 2 is novel side cross-sectional view;
Wherein: 1. arc shell; 2. locating hole; 3. placed channel.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, embodiment does not form restriction of the present utility model:
An intracranial lesion puncture aid, is characterized in that, comprises arc shell 1, also comprises the placed channel 3 through arc shell 1.Therefore can realize accurate location.
Described placed channel 3 is right angle or acute angle with the plane included angle at the contact point place of arc shell 1.Described arc shell 1 is sphere.But because people's head dummy is different, so cambered surface must be not necessarily sphere, but sphere as calculate accurate a kind of preferably.
Described placed channel 3 is connected with arc shell 1.Can be equally also following scheme: described placed channel 3 and arc shell 1 releasable connection, have more than one locating hole 2 on described arc shell 1.Described arc shell 1 has two-layer, the two small one and large one and arranged concentric, the size in the hole on the two is identical.Therefore by the locating hole through two-layer arc shell 1 by placed channel 3, can accurately locate.
Described arc shell 1 has two-layer and connects by support.Described placed channel 3 is hollow cylindrical.Described placed channel 3 is transparent material.Described placed channel 3 is PVC material.This locates preferred PVC material, is not limited to this material, and similarly material is also in this novel protection domain.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand this utility model and not be restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope.
