Description
Technical field
The present invention relates to the field of medical instrument technology more particularly to a kind of scalp for neurosurgery operation of opening cranium to strut
Device and its application method.
Background technique
Dilator is a kind of common operation such as neurosurgery operation of opening cranium especially Burr-hole craniotomy, puncture drainage
Instrument is mainly used for sufficiently strutting scalp tissue, thoroughly exposes skull, operates convenient for operation of opening cranium.Usual row in surgical procedure
Scalp linear type notch, holostrome are all propped up notch cortex using dilator after cutting scalp, sufficiently appear skull, then sharp
Cranium is opened in electricity consumption drilling row drilling.But clinically there is no special scalp device for spreading, use after usually expanding incision of scalp
Mastoid process dilator exposes skull, though this method can sufficiently expose, since skin incision is excessive, makes to stop blooding in operation and seam
It closes the time to increase, is unfavorable for surgical procedure.And scalp is arranged successively by five different levels and is formed, including skin, subcutaneous
Connective tissue, occipitofrontalis and galea, loose connective tissue and cranial periosteum.When dilator and skull contact, due to skull
Surface is arc-shaped, and the fixed linear type design of dilator head end cannot be bonded skull surface completely, it is difficult in the start-stop point of notch
Place's holostrome struts scalp, causes skull exposure insufficient, influences operation of opening cranium operation.Therefore being clinically badly in need of one kind can be bonded
Skull surface, the scalp dilator for strutting scalp holostrome, utmostly exposing skull.
Summary of the invention
It is an object of the invention in view of the shortcomings of the prior art, providing a kind of for neurosurgery operation of opening cranium
Scalp dilator and its application method.
The purpose of the present invention can be realized by following technical solutions:

Diameter of section is equal.
Further, the left lever arm, right lever arm upper end outside are fixed there are two hook is strutted, and lower end is provided with ball
Head is adapted with the size of the ball cup.
Further, the diameter of the bulb is less than end cross-section diameter on the left lever arm, right lever arm.
Further, the hook that struts is passivity hook.
A kind of its application method of scalp dilator for neurosurgery operation of opening cranium of the present invention, including it is following
Step:
Step 1. positioning linear notch cuts holostrome scalp, trip lock tooth spanner, and opening struts handle, and closure struts arm and activity
Arm；
Step 2. will strut arm and lever arm is placed on incision, rotate lever arm to scalp direction centered on ball pin structure,
Make to strut arm and lever arm fitting scalp curved surfaces；
Step 3. struts the holostrome scalp tissue for strutting hook and hooking notch two sides on arm and lever arm with left and right, pinches and holds together to strut
Handle, opening strut arm and strut notch, and lever arm is centered on ball pin structure, to notch medial movement, make notch in approximate circle,
Utmostly expose；
Step 4. checks lock tooth spanner, it is ensured that lock toothing locking makes scalp dilator maintain softened state.
The advantageous effects that the present invention has:
Compared with prior art, a kind of scalp dilator structure for neurosurgery operation of opening cranium of the invention is simple, uses
It is convenient and efficient.Using with ball pin structure jaggy, guarantees that lever arm rolls tiltedly to scalp, make to strut arm upper end and lever arm all
Skull curved surfaces are tightly bonded, entire notch two sides holostrome scalp tissue can be strutted；The ball pin structure also makes activity simultaneously
Arm can make notch in approximate circle to notch medial movement while strutting notch, expose visual area to the greatest extent, reduce
The length of notch shortens operating time, is convenient for surgical procedure.
