Description
Technical field
The utility model relates to the field of medical instrument technology, specially a kind of surgical wound pull device.
Background technique
In surgical procedure, medical staff needs to position musculature, blood vessel, nerve and other by its pull device
Tissue, so that being close to operating position.It is all even more important in the operation many surgical procedures of pull device, is especially having
Close the operation of the cerebrovascular and nerve.Traditional brain tissue retracts and the foundation of operation path is logical mainly by brain spatula (stainless steel substrates)
The anatomical structure that manpower utilizes cranium brain is crossed, brain tissue is retracted, relies primarily on the professional skill and experience of patient, and retracting brain
The destruction of the cerebrovascular and nerve is be easy to cause during tissue, brain retraction injury is seen everywhere, and due to brain tissue after traction
Creep characteristic, the channel expanded, which is easy to shrink, to become smaller, and influences surgical procedure.It is directly retracted using brain spatula and needs biggish bone window
It is operated, wound is big, is easy infection, and patient's recovery time is long, and very big pain and heavier economy are brought to patient
Burden.Further, for needing to carry out the operation of brain parenchym traction, brain spatula is helpless, and needs using electricity
Solidifying knife is cut, however electric coagulation knife be easy to in brain tissue nerve and blood vessel cause it is irreversible damage and lose brain
Partial function is lost, patient's death is even resulted in.
Currently, application No. is the Chinese patents of CN201520913056.6 to disclose a kind of brain pull device, one is provided
Kind brain pull device, comprising: flexibility retracts component, cooperates including dilating sacculus, support tube, attachment base and attachment base locking
Retaining mechanism and with expand or shrinkage expansion sacculus pressurizing device connector；Brain spatula is sheathed on the remote of flexible traction component
It holds and enters and retracted in the traction channel that component retracts by flexible so that retracting channel keeps traction state.
In the course of surgery, medical staff should farthest reduce the wound to patient and the damage to tissue, subtract
The pain of few sufferer.And brain retractor described in the above-mentioned patent brain pull device, by being injected in pressurizing device connector
Liquid is so that dilating sacculus is expanded and dilating sacculus is shunk when extracting liquid out, by infusing in quantitative control pressurizing device connector
Brain spatula is then directly inserted in accurately to control the expansion diameter of dilating sacculus and flexible retracts component and brain group by the amount of liquid entered
Between knitting.During brain spatula is inserted in, the damaged tissues phase mutual friction of brain spatula and wound circumference, to wound and its surrounding
Tissue cause secondary injury, be easy to cause the increase of amount of bleeding and the expansion of wound, patient can be caused unnecessary wound and
Pain；And step is relatively more, occupies the regular hour, and needs to do the surgical procedures such as stop blooding for sufferer.
Utility model content
The purpose of this utility model is to provide for a kind of surgical wound pull device, the wound that will need to retract in operation

Inner cavity 2 or the axial cavity 22 axially extending along tube wall 1, axial cavity 22 in wall 1 are distributed in tube wall 1 with proportional spacing
It is interior, the anti-folding of bending resistance.Guarantee that shape change does not occur for deformation pipe sleeve after solidify liquid solidification in same axial cavity 22.
Via hole 3 is corresponding with the position of annular chamber 21 or axial cavity 22 in the position in 1 outside of tube wall, when deformation pipe sleeve is logical
Road expansion, after 3 aperture of via hole becomes larger, extraneous water and air can preferably and the solidification inside annular chamber 21 or axial cavity 22
Liquid preferably contacts solidification.
2 structure of inner cavity is as shown in Figures 3 and 4 in the present embodiment, inner cavity 2 include along tube wall 1 circumferentially around annular chamber
21 and the axial cavity 22 axially extending along tube wall 1, and annular chamber 21 and axial cavity 22 are interconnected, and such cavity body structure can
To better ensure that the stability of deformation pipe sleeve shape after hardening.
The solidify liquid filled in inner cavity 2 is α-cyanoacrylate.α-cyanoacrylate meets water or moist empty
Gas is catalyzed, and solidification can be adhered rapidly, is the utility model in the curable deformation pipe sleeve of intranasal endoscopic surgery
The preferable material of solidify liquid.
Pipe sleeve is deformed in the utility model and is divided into front end and end, and front end and end both ends bore are different, and front end bore is
The 3/4 of end bore.Beloid deformation pipe sleeve facilitates front end to enter nasal cavity, convenient for operation.
The outer surface of deformation tube casing wall 1 is equipped with hemostasis coating, and hemostasis coating is mainly used for vessel retraction in mucous membrane or adds
Fast blood clotting.
Contain adrenaline in hemostasis coating, adrenaline can stimulate blood vessel to make vessel retraction, reach the mesh of hemostasis
's.
The above makes preferred embodiments of the present invention, does not depart from for those of ordinary skill in the art
Under the premise of the utility model principle, several variations and modifications can also be made, these also should be regarded as the protection of the utility model
Range.
