Abstract
A skull perforation stop gasket is made of medical latexes, with a hollow circle in the center of the gasket, and a cutting line that has been cut is arranged between the circumference of the gasket and the outer ring of the hollow circle. With the structure as above, the utility model can utilize the skull perforation stop gasket with different sizes to measure the length that needs to be set aside for the aiguille, and accurately penetrate the skull with selection of the proper thickness covered on the aiguille to set aside the skull thickness, wherein the scalp is touched but can not be hurt after the skull is penetrated because the utility model is soft. Additionally, the excessively long sleeve used for the microinvasive surgery of encephalic hematoma evacuation can be fixed by the utility model to prevent the puncture needle from penetrating too deep, and prevent the brain tissue from being damaged.
Description
Technical field
This utility model relates to the medical operating utensil that a kind of sphenotresia is used.
Background technology
Neurocranial surgery operation and the treatment of hypertensive cerebral hemorrhage microtrauma puncture all need sphenotresia, accurately the degree of depth of control drill bit is to avoid the key of injured brain tissue and blood vessel, and the degree of depth of controlling drill bit at present usually causes brain injury because the undesirable drill bit of control enters intracranial mostly with doctor's experience and hand control proficiency level.And present metal stop is that external fixation is in the puncture needle outside, be easy to press from both sides flat trocar sheath, metal stop and electric drill rotate synchronously, boring behind the skull metal stop contacts moment and easily causes scalp injury with scalp, the position of fixing metal stop is many estimates length with the doctor, having error, is not bore skull to take an advanced study into brain tissue impairment exactly excessively.
Summary of the invention
The purpose of this utility model provides a kind of sphenotresia spacing shim that can not cause brain injury and scalp injury.
The purpose of this utility model is achieved in that with medical latex and makes, and is open circles in the middle of the pad, and the circumference of pad has the line of cut of having cut open between the cylindrical of open circles.
Because this utility model adopts said structure, can utilize different size sphenotresia spacing shim to measure the length that to reserve drill bit, choosing suitable thickness is enclosed within drill bit outside and reserves skull thickness, can accurately bore skull, and because of its softness, bore behind the skull not contact and can injure scalp with scalp, in addition, the long this utility model that can utilize of intracranial hematoma microscopic wound dissection trocar sheath is fixed, and it is dark to prevent that puncture needle was strayed into, and avoids injured brain tissue.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
1 line of cut of having cut open, 2 pads, 3 open circles among the figure.
The specific embodiment
Embodiment: this spacing shim is made with medical latex, is open circles 3 in the middle of the pad 2, and the circumference of pad 2 has the line of cut of having cut open 1 between the cylindrical of open circles 3.These pad 2 diameters are 10mm, open circles 3 diameters are 4mm, thickness can be made 1mm respectively, 2mm, 3mm, 4mm, 5mm, 10mm, 20mm, eight specifications of 30mm, calculate skull and scalp thickness according to head CT, the puncture needle length overall deducts desiring of calculating and stays the length of drill bit will choose pad 2 thickness exactly, utilize combination of the present utility model can obtain the pad 2 of suitable thickness, because of its softness, utilize the line of cut of having cut open 1, before boring skull, pad 2 is enclosed within the puncture needle outside, bores behind the skull owing to stopping of pad 2 can avoid puncture needle to continue to enter.The patient who keeps hard passage constant drainage can select for use the pad 2 of appropriate length to be enclosed within the unnecessary hard passage of hard passage fixed outside and prevent that its mistake from entering intracranial.
Claims (1)
1, a kind of sphenotresia spacing shim is made with medical latex, it is characterized in that: be open circles in the middle of the pad, the circumference of pad has the line of cut of having cut open between the cylindrical of open circles.
