Abstract
The utility model discloses an adjustable manual craniotome ring saw, comprising a swivel body, and a ring saw. The upper end of the swivel body is provided with a swivel head boss; one side on the lower end of the swivel body is provided with a slide groove. A slide plate inserts into the slide groove through the bottom end of the slide groove, and then inserts into a rectangular slide plate hole of the ring saw. The utility model has the advantages of easy production, safe and convenient operation, and accurate and adjustable depth of the skull-drilling, and greatly decreases the wound caused by careless operation in craniotomy, avoiding the complicating disease, and without affecting the appearance of the patient.
Description
Technical field
This utility model relates to medical apparatus and instruments, is specially a kind of adjustable manual and opens the cranium trepan.
Background technology
Open clinically in the cranium art, when needs ossiculum window is opened the capable encephalic operation of cranium, adopt mostly at present to bore on skull with drill for craniotomy earlier and open the about 1 centimetre hole of diameter, bite the bone window that skull reaches required size broken by rongeur then.This technology exists in boring the cranium process, and it is unpredictable that drill bit enters the degree of depth, and the bone cips that skull is bitten broken can't Hui Zhi, and the edge is whole; Postoperative is lost easily defect of skull, influences patient's good looking appearance and causes certain psychological burden to patient.
Summary of the invention
The purpose of this utility model provide a kind of have make simple, easy-to-operate, the brill cranium degree of depth is accurately adjustable, the wound that causes accidentally in the time of can significantly reducing out cranium, and can avoid the generation of complication, do not influence patient's good looking appearance, in process of clinical application, have certain applying and open the cranium trepan with the adjustable manual of society, economic worth.
The purpose of this utility model is achieved through the following technical solutions: adjustable manual is opened the cranium trepan, it is turned, trepan, the upper end of turning is provided with the rotary head boss, has chute in lower end one side of turning, and slide plate inserts in the rectangle slide hole of trepan after inserting in the chute by the chute bottom again.There is a groove edge of described chute, and screw is movably arranged in the groove.One side of described chute is provided with scale.
The beneficial effects of the utility model are: the degree of depth of opening cranium can be determined according to the skull thickness that CT shows, have make simple, easy-to-operate, the brill cranium degree of depth is accurately adjustable, the wound that causes accidentally in the time of can significantly reducing out cranium, and can avoid the generation of sequela and complication, in process of clinical application, have certain applying and the advantage of society, economic worth.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the perspective view of Fig. 1.
The specific embodiment
Adjustable manual of the present utility model is opened the cranium trepan, it turns 1, trepan 5, it is characterized in that: 1 the upper end of turning is provided with the rotary head boss, has chute 2 in 1 lower end, one side of turning, and slide plate 4 inserts in the rectangle slide hole 6 of trepan 5 after inserting in the chute 2 by chute 2 bottoms again.There is a groove edge of described chute 2, and screw 7 is movably arranged in the groove.One side of described chute 2 is provided with scale 3.
The skull thickness that shows according to the CT sheet during operation is selected the saw bone degree of depth, by the fixing required height of trepan of expansion screw.Crank is inserted in 1 the boss of turning, and the rotation trepan is when trepan is sawed into skull, slide plate 4 promptly moves up in chute 2, stop sawing when rising to the degree of depth of setting, prevented original technology because undue force or lack experience, and damage cerebral dura mater and cerebral tissue cause complication.The technology that this utility model is not described in detail partly is known technology.
