Embodiment shows a kind of operations with sting device is retracted, and is used for brain surgery.As shown in Figure 1A, Figure 1B, this reality
Applying the example operation traction sting device includes retractor 10, sheath 20.The retractor 10 is nested in the sheath 20,
The retractor 10 can axially move with sheath 20.
As shown in Fig. 2A, Fig. 2 B, Fig. 2 C, Fig. 2 D, the retractor 10 includes operating side 13, intrusion end 11 and between the two
Main body 18.20 sets of the sheath cooperates with retractor, the operating side 13 of the retractor and invades outside retractor main body 18
Enter the outside that end 11 is exposed to sheath.18 cross section of main body of the retractor 10 is circle, and the intrusion end 11 is smooth
Cone.The retractor main body 18 is integrally formed with intrusion end 11.0.8-1.5cm long, the example in intrusion end 11 of the retractor
Such as: 0.8cm, 0.9cm, 1cm, 1.1cm, 1.2cm, 1.3cm, 1.4cm, 1.5cm, etc..
As shown in Fig. 3 A, Fig. 3 B, Fig. 3 C, Fig. 3 D, the sheath 20 includes intrusion end 21, endpiece 22 and operating side 23, institute
Endpiece 22 is stated close to the operating side 23, the operating side 23 is set to the edge of the endpiece 22.Retractor invade end 11 from
The opening at sheath intrusion end 21 is pierced by and blocks the opening at sheath intrusion end 21.
When work, 20 sets of sheath outside retractor 10, make retractor intrusion end 11 stretch out sheath 20, the sheath that will be assembled
Pipe 20 and retractor 10 are invaded from suitable position, until sheath intrusion end 21 arrival target area, are at this time removed retractor 10
Out, sheath 20 remains stationary, and forms an operation path.Cerebral operations in use, 20 sets of sheath outside retractor 10 such as
Shown in Figure 1B, by the combination unit from the brain tissue of the operative incision of patients head insertion patient, invaded by conical retractor
End 11 retracts brain tissue, and after reaching target position, fixed sheath 20 takes out retractor 10, and the end 21 of sheath intrusion at this time is open
It is directed at lesions position, can be performed the operation by 25 access instruments of sheath pipe through-hole.10 main body of retractor uses cylindrical structure, makes
Stress is retracted in approach operating process to be uniformly distributed, nerve conduction beam is damaged to reduce, and is reduced cerebral operations operation and is drawn
Play the risk of sequelae.
Embodiment more preferably, in order to make surgical instrument obtain biggish activity space in sheath, such as Figure 1A, figure
3C, the fit system between the sheath and retractor is: main body to the retractor from the operating side of retractor along retractor is invaded
Enter end in the progressive formation by clearance fit to interference fit.Retractor invades the cone cell outer surface at end 11 and sheath invades end 21
Coniform outer surface smoother transition, to avoid in structure fracture cutting brain tissue formed secondary injury.The sheath endpiece
22 is gradually outwardly open, in the shape of a trumpet.As shown in Figure 1A, Fig. 2A -2D, the retractor main body uses engraved structure 12.Institute
State the 5%-40% that engraved structure accounts for retractor body peripheral face product.The design of engraved structure is primarily to mitigate weight and satisfaction
The demand of moulding process.Elastic appropriateness is answered in the cooperation of sheath 20 and retractor 10, on the one hand guarantees that the two will not in progradation
It disengages, excessive resistance will not be generated when another aspect retractor is withdrawn from；From the operating side of retractor along retractor main body to
It is in the gradual change by clearance fit to interference fit that retractor, which invades end,.The cooperation of sheath 20 and retractor 10 is the key point of technology
One of, it is excessive that cooperation tightly will lead to very much resistance when retractor is withdrawn from from sheath；The seam loosely cooperated between retractor and sheath
Gap is possible to cause to cut to tissue in approach operating process.
Embodiment more preferably, as shown in Figure 2 A, the sheath and the retractor can using locking member formation
Dismantling connection, the locking member is for the sheath to be fixed on outside the retractor main body.The locking member includes convex
Structure 16 and position limiting structure 17 are played, the bulge-structure is for fixing sheath intrusion end, and the position limiting structure is for limiting sheath
Operating side.The position limiting structure 17 is the reinforcing rib being set between retractor main body 18 and retractor operating side 13, described
The structure with the cooperation of sheath operating side is provided on reinforcing rib, make be in from radially and circumferentially between sheath 20 and retractor 10
Stationary state.The bulge-structure 16 is set in the retractor main body close to the position at retractor intrusion end, is invaded with sheath
Enter to hold inner surface tight fit.
Embodiment more preferably, as shown in Figure 1A, the retractor 10 are equipped with guide hole 15 and locking device 30, institute
Guide hole 15 is stated for being inserted into guide device, the locking device 30 is for fixed be inserted into guide device.The guide hole
15 are extended to inside retractor intrusion end 11 by retractor operating side 13.The locking device 30 is set to retractor operating side 13
On.The locking device includes along guide hole radially deeply to the bolt of guide hole and the screw cooperated with bolt.Guide hole 15
With the setting of locking device 30, makes to retract operation while guide device can be cooperated to complete.
Embodiment more preferably, as shown in Fig. 2A -2D, Fig. 3 A-3D, during approach, the depth of retractor insertion
It is determined by tip location, operation requires sheath tube opening to cope with quasi- lesions position, in order to accurately know two location informations, more preferably
Design be that retractor 10 and 20 surface of sheath have graduation indication, convenient for medical worker obtain depth information, as retractor carve
Shown in degree 14 and sheath scale 24.The sheath 20 is transparent two kinds with inner face frosted.The retractor 10 is selected from biology
The material that compatibility meets medical requirement is made；The sheath 20 is made selected from the material that biocompatibility meets medical requirement.
The material of sheath 20 is not squeezed and deformed vulnerable to brain tissue；In order to reduce intrusion resistance, contact tissue outer surface answer it is smooth.
Operation provided by the utility model is used cylindrical structure, is made into dataway operation mistake with sting device, retractor is retracted
Stress is retracted in journey to be uniformly distributed, nerve conduction beam is damaged to reduce, and is reduced cerebral operations operation and is caused sequelae
Risk.Sheath operating side horn mouth provides biggish surgical instrument operation space；The operation path stabilization that sheath provides is not variable
Shape；Sheath scale can facilitate medical worker to understand insertion depth.Sting device, Ke Yishi are retracted by using the utility model
When present clinician carries out cerebral operations operation, low-wound is carried out to patient's brain tissue and retracts puncture procedure, reduction perform the operation into
Damage of the dataway operation to patient's brain tissue reduces postoperative complication, while can provide biggish surgical procedure space for doctor again.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
