Diagnosis, treat and prevent technology a high, precision and frontier subject.
Neurosurgery is often after Epidural cavity, Subdural space, tumor residual cavity, wound chamber or the ventricles of the brain place drainage tube with drainage
Remaining hematocele or oozing of blood, since drainage tube communicates with the outside world, which adds the chances of infection, if nursing is improper to be sent out
Raw drainage-fluid adverse current, Yi Fasheng intracranial infection, the state of an illness is critical if infection occurs, and case fatality rate and disability rate are higher, and lives
Institute's time extends, and increases patient's financial burden.
Summary of the invention
The invention is intended to provide a kind of scalpel for neurosurgery, to solve to do neurosurgery using the prior art
When, the problem of being easy to happen drainage-fluid adverse current.
In order to solve the above technical problem, the present invention provides following technical solutions: a kind of scalpel for neurosurgery, including
Blade and knife handle, the blade are fixedly connected with knife handle, and horizontally disposed pipette is fixedly connected on the knife spine of the blade,
The pipette is equipped with suction nozzle close to one end of blade, and the one end of the pipette far from blade is through knife handle and extends to knife handle
Outside, piston is equipped in the pipette, is fixedly connected with catch bar on the piston, the catch bar far from piston one
End is located at the outside of pipette, is additionally provided with through-hole in the pipette, the through-hole is located in knife handle, on the hole wall of the through-hole
Equipped with groove, it is fixedly connected with the first elastic component in the groove, is fixedly connected on first elastic component logical for sealing
The baffle in hole, the baffle are slidably connected with groove, and the upper surface of the baffle is equipped with vertically supports bar, the top for supporting bar
End is located at the lower section of catch bar and is reserved with gap between catch bar；The knife handle is equipped with air bag, is equipped in the knife handle
Upper plenum and lower cavity, the upper plenum is interior to be equipped with the second elastic component and piston rod, one end of second elastic component and fixation
Be connected in upper plenum, the other end of second elastic component is connect with piston rod, the piston rod through knife handle and with promotion
Bar is fixedly connected, and the piston rod is slidably connected with knife handle, and the air bag is connected to upper plenum and is located at the second elastic component and work
Between stopper rod, the piston rod, lotion pipeline and knife handle are respectively positioned on same vertical plane, the through-hole on the lower cavity and pipette
Connection, the knife handle are equipped with leakage fluid dram, and the leakage fluid dram is connected to lower cavity, is additionally provided on the knife handle for sealing drain
The sealing cover of mouth.
The working principle of the invention:
Scalpel for neurosurgery in the present invention, when doing neurosurgery to patient, doctor grasps knife handle,
Then it is performed the operation using blade, when generating hematocele and oozing of blood in the course of surgery, doctor is first by the suction nozzle in pipette
It is put into hematocele and oozing of blood, then squeezes the air bag on knife handle, the gas in such air bag advances in upper plenum, in this way
With regard to pushing piston rod movement, because piston rod and pipette and knife handle are respectively positioned on same vertical plane, piston is equipped in pipette,
Catch bar is fixedly connected on piston, catch bar is located at the outside of pipette, the piston rod in upper plenum far from one end of piston
It is fixedly connected through knife handle and with catch bar, piston rod is slidably connected with knife handle, therefore piston rod is to upper plenum external movement
In the process, just catch bar is driven to pull piston motion, and then hematocele and oozing of blood is drawn into pipette.
Because being additionally provided with through-hole in pipette, through-hole is located in knife handle, and through-hole is connected to lower cavity, the hole wall of through-hole
It is equipped with groove, the first elastic component is fixedly connected in groove, the gear for sealing through-hole is fixedly connected on the first elastic component
Piece, baffle are slidably connected with groove, and the upper surface on baffle is equipped with vertically supports bar, and the top for supporting bar is located under catch bar
It is reserved with just and between catch bar gap, as catch bar pulls piston motion, piston, which just will push, supports bar movement, in turn
Squeeze the first elastic component in groove, and then baffle pushed to enter in groove, the position to through-hole be located at suction nozzle and piston it
Between when, hematocele and oozing of blood in pipette just pass through through-hole and enter in lower cavity, in pipette hematocele and oozing of blood flow into
After into lower cavity, air bag is unclamped, the second elastic component is returned to original state, and piston rod bounces back into upper plenum, and then pulls
Catch bar pushes piston motion, and baffle is due to the restoring force of the first elastic component, when piston completely with supporting bar and being detached from when, baffle
Just through-hole is sealed；When the hematocele generated in surgical procedure and oozing of blood to be sucked out again, aforesaid operations are repeated.
Beneficial effects of the present invention:
When doing neurosurgery to patient using this programme, when the hematocele and oozing of blood that generate in operation need to absorb,
Only need to squeeze air bag on knife handle, the gas in air bag enters in upper plenum, external movement from extrusion piston bar to upper plenum,
The catch bar movement in pipette is driven, and then drives piston motion, hematocele and oozing of blood are drawn into pipette, with piston
Movement, promotion supports bar movement so that the first elastic component is compressed, and then hematocele and oozing of blood just pass through through-hole and be flowed into lower sky
In chamber, air bag is finally unclamped, piston rod is returned to initial conditions under the restoring force of the second elastic component, when piston and supports bar
When not contacting, baffle again seals the through-hole in pipette, prevents hematocele and oozing of blood from leaking out.Compared to existing technologies, it uses
When the application does neurosurgery to patient, there is no need to reuse drainage tube to arrange the hematocele of Postoperative Residual and oozing of blood
It removes, and the application whole operation process will not be contacted with the external world, realized the integration of imbibition and drain, subtracted as far as possible
Infection chance is lacked, and hematocele and oozing of blood adverse current will not occur.
Further, sponge is equipped in the lower cavity.Sponge has very strong adsorptivity, and then can will flow from pipette
The middle hematocele and oozing of blood entered to lower cavity is adsorbed.
Further, the surface on the knife handle is equipped with several skid resistance strips.When doctor grasps knife handle, hand is increased
Frictional force between knife handle prevents scalpel in surgical procedure to slide from the hand of doctor as far as possible, prevents from accidentally injuring and suffer from
Person.
Further, the sealing cover is threadedly coupled with knife handle.The mode structure of threaded connection is simple, processing easy to produce,
Cost is effectively saved.
Further, first elastic component and the second elastic component are spring.Spring structure is simple, processing easy to produce.
