Abstract
The utility model discloses a kind of micro- scissors of cranial surgery ventricles of the brain endoscopic surgery, belong to surgical field, including the hinged blade of two panels, be arranged on the back side of the blade it is fluted, be provided in the groove can along groove notch be retracted and stretch out blade back side blade.This scissors is not in the case where influencing blade size, by designing telescopic blade in blade back side, make blade that there is Double-blade structure, when implementing to perform the operation to tumour, after need to only blade being allowed to enter tumour, by can realize flaring operation to tumour by drawing blade again after opening blade and stretching out blade, have structure simple, easy to use, efficiently effect.
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 microscissors
Knife.
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 is both needed to effectively expand tumour notch to the multiple shearing of tumour progress broken at present, to avoid
Tumour notch it is too small and in the risk that the later period heals again, thus operate 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
The micro- scissors of operation, is embodied in header terminal design, keeps most important shearing flaring operation in ventricles of the brain endoscopic surgery more convenient, fast
It is prompt.
The utility model is achieved through the following technical solutions:
A kind of micro- scissors of cranial surgery ventricles of the brain endoscopic surgery, including the hinged blade of two panels, the blade
Be arranged on back side it is fluted, be provided in the groove can along groove notch be retracted and stretch out blade back side blade.
Further, further include pull rope mechanism for opening and closing blade, by skewback, the first spring, second spring, pin shaft, drawing
Rope composition, one end of blade are articulated in groove by pin shaft, and the other end is connected with the first spring, and one end of drawstring and setting exist
Skewback connection in groove, the other end are connected at scissors handle, and skewback is slidably matched with groove, and second is connected on skewback
Spring.
Further, a piece of or two panels blade front end is set as tip.
Further, helical edges are provided on the tip.
The advantageous effects of the utility model are: this scissors is not in the case where influencing blade size, by blade
Back side designs telescopic blade, and blade is made to have Double-blade structure, when implementing to perform the operation to tumour, need to only blade be allowed to enter tumour
Afterwards, by that can realize flaring operation to tumour by drawing blade again after opening blade and stretching out blade, there is structure letter
It is single, easy to use, efficiently effect.
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 blade open state structural schematic diagram of the utility model；
Fig. 2 is the blade closed state structural schematic diagram of the utility model；
Fig. 3 is the blade open state structural schematic diagram of the utility model；
Appended drawing reference, blade 1, blade 2, skewback 3, the first spring 4, second spring 5, pin shaft 6, drawstring 7, tip 8, spiral
Sword 9.
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 Figure 1-3, a kind of cranial surgery ventricles of the brain endoscopic surgery micro- scissors, including two panels provided by the utility model
Hinged blade 1, is arranged on the back side of blade 1 fluted (unmarked), and being provided in the groove can be along groove notch
Retraction and the blade 2 for stretching out blade back side.Specifically, the opening and closing of the blade is controlled by pull rope mechanism, the pull rope mechanism is by oblique
Block 3, the first spring 4, second spring 5, pin shaft 6, drawstring 7 form, and one end of blade 1 is articulated in groove by pin shaft 6, another
End is connected with the first spring 4, and one end of drawstring 7 is connect with the skewback 3 being arranged in groove, and the other end is connected to scissors handle
Place, skewback 3 is slidably matched with groove, and second spring 5 is connected on skewback 3, i.e., by scissors handle to the one of drawstring
After end is pulled, the movement of traction skewback and promote blade to stretch out groove, meanwhile, skewback and blade are by the first spring and the
The pulling force effect of two springs, if unclamping drawstring makes, and skewback and blade reset under the effect of respective spring.Using above-mentioned side
Case, this scissors, by designing telescopic blade in blade back side, have blade double in the case where not influencing blade size
Sword structure after need to only blade being allowed to enter tumour, be led to again when implementing to perform the operation to tumour after stretching out by opening blade and by blade
Flaring operation can be realized to tumour by crossing drawing blade, have structure simple, easy to use, efficiently effect.
A piece of or two panels blade 1 front end in the present embodiment is set as tip 8.Scissors can be enabled suitable by tip
In the piercing tumour of benefit, the flaring of tumour is operated after being opened convenient for subsequent blades.Preferably, helical edges are provided on tip 8
9.By the design, being not easy to puncture in tumour makes, and helical edges can be made smoothly to break tumour by rotating scissors.
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.
