Abstract
The invention discloses a kind of new-type dural knife, it is related to medical instruments field, doctor can hold handle to the new-type dural knife when in use, and insert a thumb into the thumb collar.Doctor can stretch meningeal tissue first with dural retractor in operation, then drive control stick to control cutting knife to move by swinging thumb, and coordinate the rotation of wrist that cutting knife is cut away to the meningeal tissue being straightened.The new-type dural knife is cut again after can meningeal tissue be stretched, and improves the accuracy of operation, and everything is disposably completed, simple to operate, and the success rate of Cerebral surgery can be allowed to be lifted.
Description
Technical field
The present invention relates to medical instruments field, and specifically the present invention relates to a kind of new-type dural knife.
Background technology
Doctor usually cuts meninx when doing Cerebral surgery using dural knife.But existing dural knife designs mostly
Simply, only blade shapes with tip, meningeal tissue can not be stretched by using, and cause easily to occur in cutting process inclined
Difference, operation accuracy are difficult to ensure.Existing dural knife function is single, can not meet what modem surgical was cut for meningeal tissue
It is required that.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of new-type dural knife, enter again after can meningeal tissue be stretched
Row cutting, improves the accuracy of operation, simple to operate, and the success rate of Cerebral surgery can be allowed to be lifted.
To achieve the above object, the present invention provides following technical scheme：
The new-type dural knife includes the handle of direct rod shape, and handle front end is straight to be provided with spiral circle cylindrical spring, handle front end
It is provided tiltedly with dural retractor, dural retractor is bent towards spring direction, and dural retractor and spring are into 30 ° of angles, spring end
Support ball provided with spheroidal, support ball bottom is vertical to be provided with the cutting knife with tip, and support ball plan vertical is provided with the manipulation of L-shaped
Bar, control stick extend towards handle orientations, and manipulate the thumb collar that boom end is provided with annular.
Preferably, the cutting knife, dural retractor, support ball, control stick, spring, the thumb collar, handle are by stainless steel
To make, handle is fixedly connected by welding with dural retractor and spring, and support ball is fixedly connected by welding with cutting knife, control stick,
Control stick is fixedly connected by welding with the thumb collar.
Preferably, the length of the spring with it is longer than the length of dural retractor.
Preferably, the length of the control stick is longer than the length of spring, the length of the length of control stick than spring and handle
Sum is short.
Preferably, the internal diameter of the thumb collar is between 2~4cm.
Beneficial effect using above technical scheme is：Doctor can hold handle to the new-type dural knife when in use, and
Insert a thumb into the thumb collar.Doctor can stretch meningeal tissue first with dural retractor in operation, then pass through swing
Thumb drives control stick to control cutting knife to move, and coordinates the rotation of wrist that cutting knife is cut away to the meninx being straightened
Tissue.The new-type dural knife is cut again after can meningeal tissue be stretched, and improves the accuracy of operation, everything one
Secondary property is completed, simple to operate, and the success rate of Cerebral surgery can be allowed to be lifted.
Brief description of the drawings
The embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the front view of the new-type dural knife of the present invention；
Fig. 2 is the left view of the new-type dural knife of the present invention.
Wherein, 1- cutting knifes, 2- dural retractors, 3- supports ball, 4- control sticks, 5- springs, the 6- thumbs collar, 7- handles.
Embodiment
The preferred embodiment of the invention will now be described in detail with reference to the accompanying drawings new-type dural knife.
Fig. 1 and Fig. 2 shows the embodiment of the new-type dural knife of the present invention：
With reference to Fig. 1 and Fig. 2, the new-type dural knife includes the handle 7 of direct rod shape, and the front end of handle 7 is straight to be provided with spiral cylinder
Shape spring 5, the front end of handle 7 are provided tiltedly with dural retractor 2, and dural retractor 2 is bent towards the direction of spring 5, and dural retractor 2 and bullet
Spring 5 has ensured that dural retractor 2 can catch on meningeal tissue below spring 5, has allowed spring to be located on meningeal tissue into 30 ° of angles
Side.The end of spring 5 is provided with the support ball 3 of spheroidal, and the support ball 3 of spheroidal design is rounder and more smooth, is not easy scratch and destroys human body
Organ.
As shown in figure 1, support ball 3 bottom is vertical to be provided with the cutting knife 1 with tip, support ball 3 plan vertical is provided with the behaviour of L-shaped
Vertical pole 4, control stick 4 extend towards the direction of handle 7, and the end of control stick 4 is provided with the thumb collar 6 of annular.Because spring 5 can be with
Any bending, elongation, shorten, can be by the control operation bar 4 of the thumb collar 6 and support ball 3, to drive cutting knife 1 to cut
Action, operates very flexible.
Cutting knife 1, dural retractor 2, support ball 3, control stick 4, spring 5, the thumb collar 6, handle 7 by stainless steel making,
Sturdy and durable, elasticity is good, and corrosion resistance and good, and handle 7 is fixedly connected by welding with dural retractor 2 and spring 5, supports
Ball 3 is fixedly connected by welding with cutting knife 1, control stick 4, and control stick 4 is fixedly connected by welding with the thumb collar 6.Spring 5
Length and the length than dural retractor 2 are long, can ensure that cutting knife 1 is located at the front of dural retractor 2.The length of control stick 4 is than spring 5
Length length, the length of control stick 4 is shorter than the length sum of spring 5 and handle 7, ensures that user can will be big when holding handle 7
In the thumb insertion thumb collar 6.The internal diameter of the thumb collar 6 is adapted to the thumb for being inserted in most people between 2~4cm.
Doctor can hold handle 7 to the new-type dural knife when in use, and insert a thumb into the thumb collar 6.Performing the operation
Middle doctor can stretch meningeal tissue first with dural retractor 2, then drive control stick 4 to control cutting knife by swinging thumb
1 movement, and coordinate the rotation of wrist that cutting knife 1 is cut away to the meningeal tissue being straightened.The new-type dural knife can incite somebody to action
Meningeal tissue is cut again after stretching, and improves the accuracy of operation, and everything is disposably completed, simple to operate,
The success rate of Cerebral surgery can be allowed to be lifted.
The above is only the preferred embodiment of the present invention, it is noted that for the person of ordinary skill of the art,
Without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.
