Description
Technical field
The utility model belongs to surgery operating technology field, and in particular to a kind of cranial surgery ventricles of the brain endoscopic surgery is led with ball knife
Pipe.
Background technique
Ventricles of the brain scope refers to a seed type of hard scope in nerve endoscope, usually by outer working sheath and it is interior have illumination,
The endoscope operation system of the channels such as flushing, attraction, work composition.Service aisle is the hardness for endoscope surgical equipment operation
Channel, general diameter < 2mm.Ventricles of the brain endoscopic technic be it is a kind of with cerebrospinal fluid and flushing liquid be illumination and observation medium scope
Technology mainly operates in the brain cell system of ventricular system and cavum subarachnoidale, and it is various to be mainly used in treatment in neurosurgery
Pathologic in hydrocephalus, arachnoid cyst and ventricular system separates.Most important instrument is that scope is dedicated micro- in operation
Scissors is fixed to head end very little in overall structure and can need rotation direction according to operation, the elongated gun-type of connecting rod
Structure.The head end of scissors only has elbow, several leading kind of straight peen, double pointed head and unicuspid pattern in the world at present, these types are cut
Cutter head end exist in surgical procedure it is defective, specifically: scissors is mainly used for cutting off and cutting off capsule in ventricles of the brain endoscopic surgery
The institutional framework of the film-forms such as arachnoid of swollen wall, adhesion and hyperplasia, these institutional frameworks are usually soft, rich in toughness and
Elasticity, freedom and mobility are larger.And clinically the used ventricles of the brain, brain pond scope are mainly that single service aisle is set at present
Meter, used scissors can not effectively cut off soft cyst wall or diaphragm at present, while need to carry out to the tumour broken more
Secondary shearing could effectively expand tumour notch, to avoid tumour notch it is too small and in the risk that the later period heals again, thus
It operates more time-consuming and laborious.
Utility model content
In view of this, the purpose of the utility model is to provide a kind of cranial surgery ventricles of the brain scopes that structure is simple and convenient to operate
Operation ball knife conduit, to improve ventricles of the brain endoscopic surgery efficiency, and it is more convenient, quick to shear flaring operation to tumour.
The utility model is achieved through the following technical solutions:
A kind of cranial surgery ventricles of the brain endoscopic surgery ball knife conduit, including bar core and the casing and lantern that are sleeved on bar core
Knife, one end of the bar core are provided with T connector, and the other end is equipped with the thread segment with casing connection, is provided with needle on the outside of T connector
Point, is arranged the lantern knife between the inside and casing of T connector, lantern knife is by respectively and on the inside of T connector and casing end wall phase
The fixed ring of contact and the knife silk being arranged between two fixed rings composition, knife silk are multiple, arrangement annular in shape.
Further, the knife silk is 8-16 root.
Further, the bar core uses polytetrafluoroethylene (PTFE), and described sleeve pipe uses nylon, nylon elastomer or polyurethane.
Further, the length of the bar core is 16-30cm.
Further, the length of the knife silk is 4-7cm.
Further, the surface of described sleeve pipe is equipped with hydrophilic superslide coating.
The advantageous effects of the utility model are: the utility model can be smooth by the tip-like front end of ball knife conduit
It punctures and enters in (or under diaphragm) tumour, and pass through the cooperation of casing and bar core so that lantern knife at cyst (or under diaphragm)
Opening is in orbicule, then can realize flaring operation to tumour or diaphragm by drawing, has structure simple, easy to use, fast
Prompt effect.Further, it is also possible to be adapted to different tumours or diaphragm by the size for adjusting the orbicule that lantern knife is opened
Flaring operation.
The advantages of the utility model attachment, will provide in the description of specific embodiment part below, partially will be from following
Description in become obvious, or recognized by the practice of the utility model.
Detailed description of the invention
It is practical to this below in conjunction with attached drawing in order to keep the purpose of this utility model, technical solution and advantage clearer
It is novel to be described in further detail, in which:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional view (and lantern knife opening state) of Fig. 1；
Appended drawing reference: bar core 1, T connector 2, thread segment 3, needle point 4, casing 5, lantern knife 6, fixed ring 7, knife silk 8.
Specific embodiment
Below with reference to attached drawing, the preferred embodiment of the utility model is described in detail；It should be appreciated that preferably real
Example is applied only for illustrating the utility model, rather than in order to limit the protection scope of the utility model.
As shown in Figs. 1-2, a kind of cranial surgery ventricles of the brain endoscopic surgery ball knife conduit provided by the utility model, including bar core
1 and the casing 5 and lantern knife 6 that are sleeved on bar core, one end of bar core 1 be provided with T connector 2, the other end is equipped with and casing 5 connects
The thread segment 3 connect, the outside of T connector 2 are provided with needle point 4, for puncturing tumour or diaphragm, the inside of T connector 2 and casing 5 it
Between lantern knife 6 is set, cooperated by thread segment between casing and bar core, lantern knife can be made to open in orbicule, certainly not
In same embodiment, thread segment cooperation can be substituted by other modes, as mechanical pencil, be pressed in bar core tail end facility
Portion by pressing press section, can equally make lantern knife open or close up, only in the structure of bar core front end setting spring
It is that the lantern knife diameter of this opening is fixed；The lantern knife 6 is by the fixation that is in contact respectively with the inside of T connector 2 and 5 end wall of casing
Ring 7 and the knife silk 8 being arranged between two fixed rings 7 composition, knife silk 8 be it is multiple, it is annular in shape to arrange, be provided with cutting edge,
It is arranged outwardly.Using the above scheme, the utility model by needle point be ball knife catheter proximal end can smoothly enter into tumour or every
Under film, and by the cooperation of casing and bar core so that it is in orbicule that lantern knife, which is opened, in this way, being bent using compressing knife silk swollen outward
Bulging glomeration tears tumour wall or diaphragm and (is similar to lantern, is in strip tubular when shrinking, be in ball in opening to pull
Shape), it can realize that destructive flaring is operated to tumour wall or diaphragm, easy to use, efficiently effect simple with structure.
It is operated further, it is also possible to be adapted to different flarings by the size for adjusting the orbicule that lantern knife is opened.
Knife silk 8 in the present embodiment is 8-16 root, and bar core 1 uses polytetrafluoroethylene (PTFE), and casing 5 uses nylon, nylon elastic
Body or polyurethane；The length of bar core 1 is 16-30cm；The length of knife silk 8 is 4-7cm；The surface of casing 5 is applied equipped with hydrophilic superslide
Layer.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, it is clear that this field
Technical staff various modification and variations can be carried out to the utility model without departing from the spirit and scope of the utility model.This
Sample, if these modifications and variations of the present invention belong to the claims of the present invention and its equivalent technology range it
Interior, then the utility model is also intended to include these modifications and variations.
