Description

Cranial nerve knife for neurosurgery intracerebral operation

Technical Field

The application relates to the technical field of medical instruments, in particular to a cranial nerve knife for neurosurgical intracerebral operations.

Background

The cranial nerve knife is mainly used for intracerebral nerve operation, and is used for dissecting intracerebral nerves, blood vessels or excising some soft tissues in the brain.

The blade of current cranial nerve sword is disposable, need carry out the joint through the fixture block on the notch of blade and the handle of a knife through the centre gripping pincers when using, thereby the equipment to cranial nerve sword is accomplished, but when carrying out the joint equipment to the blade, need align the blade slowly, then press the joint again, thereby the equipment that has led to the blade is comparatively troublesome, the direction of the force skew that can appear making simultaneously at the in-process of pressing leads to the blade departure, thereby cause the injury to the operator.

SUMMERY OF THE UTILITY MODEL

In view of the above problems, the present application provides a cranial nerve scalpel for neurosurgical intracerebral operations, which solves the problems set forth in the background art.

The utility model provides a pair of neurosurgery brain neurosurgery is interior to be operated with brain neurosurgery, including the handle of a knife, the centre gripping groove has been seted up to the left side end of handle of a knife, the inside activity in centre gripping groove is pegged graft and is had the blade, the left end of handle of a knife lateral surface is equipped with the screw thread, the left end of handle of a knife lateral surface has the thread bush through screw thread threaded connection.

Preferably, the left end of the outer side surface of the knife handle is fixedly connected with a stop block.

Preferably, finger grooves are formed in the left ends of the front side face and the rear side face of the knife handle, and the bottom surfaces of the finger grooves are arc-surface-shaped.

Preferably, the bottom of the finger groove is provided with an anti-skid block, and the anti-skid block is in a shape of a straight quadrangular prism.

Preferably, the top and the bottom of the knife handle are both provided with tiger mouth grooves, and the bottom surfaces of the tiger mouth grooves are arc-surface-shaped.

Has the advantages that:

1. this neurosurgery is cranial nerve sword for brain interior operation through screw thread, thread bush, grip block for can continue the centre gripping to the blade through the centre gripping groove, then the rethread screwed pipe extrudees the centre gripping groove both ends and presss from both sides tightly, thereby can press from both sides tightly the blade of centre gripping inslot portion, and then make the assembling process of cranial nerve sword more simple and convenient, simultaneously, the security also improves greatly.

2. This neurosurgery brain neurosurgery is cranial nerve sword for operation sets up the non slipping spur through pressing the department at the finger for the frictional force between the contact surface of finger and cranial nerve handle of a knife increases, thereby makes in the operation process, can not lead to the unexpected condition because of the hand is smooth.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present application, the drawings needed to be used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present application, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without creative efforts.

FIG. 1 is a schematic perspective view of the present invention;

FIG. 2 is a connection relationship diagram of the knife handle and the blade of the present invention;

fig. 3 is an enlarged view of a portion a in fig. 1 according to the present invention.

In the figure: 1. a knife handle; 2. a slot with a tiger mouth; 3. a finger groove; 4. a threaded sleeve; 5. a stopper; 6. a blade; 7. a clamping groove; 8. a thread; 9. and (4) anti-skid blocks.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1-3, a cranial nerve knife for neurosurgical intracerebral operations comprises a knife handle 1, a clamping groove 7 is formed in the left end of the knife handle 1, a blade 6 is movably inserted into the clamping groove 7, a thread 8 is formed in the left end of the outer side surface of the knife handle 1, and a thread sleeve 4 is connected to the left end of the outer side surface of the knife handle 1 through the thread 8.

Wherein, the left end fixedly connected with dog 5 of 1 lateral surface of handle of a knife can restrict the position of thread bush 4 through dog 5, avoids thread bush 4 after fixed to continue forward rotation under unexpected touching, and then leads to the unexpected condition to appear among the operation process.

Wherein, finger groove 3 has all been seted up to the left end of handle of a knife 1 front and back both sides face, and the bottom surface shape in finger groove 3 is the arcsurface form for when gripping the use to handle of a knife 1, thumb and forefinger can press in finger groove 3, thereby increase the comfort in the use.

Wherein, the bottom in indicate groove 3 is equipped with non slipping spur 9, and non slipping spur 9's shape is straight quadrangular prism form to can make the frictional force increase between thumb tripe and the 3 contact surface in indicate groove through the straight terminal surface at non slipping spur 9 top, simultaneously, the shape at straight quadrangular prism top is the rectangle, and then makes the thumb exert force to that direction no matter, its resistance all has the increase, thereby the unexpected condition that the smooth hand that leads to of having appeared in the use takes place.

Wherein, tiger's mouth groove 2 has all been seted up with the bottom in the top of handle of a knife 1 for when gripping the use to cranial nerve sword, the tiger's mouth can inlay in tiger's mouth groove 2, thereby make to use more stably, the shape of tiger's mouth groove 2 bottom surface is the cambered surface form, makes tiger's mouth groove 2 laminate with palm tiger's mouth position as far as, thereby makes stability better in the use, also can increase the comfort of use simultaneously.

The working principle is as follows:

when assembling blade 6 and handle of a knife 1, insert centre gripping groove 7 with the tail end of blade 6 through the centre gripping pincers, then rotate thread bush 4 for thread bush 4 moves left, thereby extrudees the front and back side of centre gripping groove 7, thereby can press from both sides blade 6 tight the fixing in centre gripping groove 7, makes the group form of blade 6 and handle of a knife 1 become more simple and convenient, simultaneously, also can not produce the potential safety hazard problem.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not necessarily depart from the spirit and scope of the corresponding technical solutions in the embodiments of the present application.
