The specific embodiment
Like Fig. 1,2,3,4, shown in 5; A kind of adjustable nerve endoscope is assisted sheath, comprises sheath pipe 1, the sheath handle 2 that is connected with the sheath pipe, sheath core 4 and nook closing member 5, and sheath handle 2 is constituted by an active connection by two shaft arms; Sheath pipe 1 is made up of two C shape pipes; This two C shapes pipe two shaft arms of corresponding with it said sheath handle 2 respectively is connected, and the shaft arm of said sheath handle 2 is provided with control valve 3, and said control valve 3 is realized that through effect and said sheath handle 1 two C shapes pipes of said sheath pipe 1 are closed and separated; Two C shapes of said sheath pipe 1 are provided with hollow sheath core 4 with matching in managing when closure, and nook closing member 5 with matching is set in the said sheath core 4; Said two C shapes pipe forms the passage of inner wide and outer narrow separately the time.
One of them shaft arm of sheath handle 2 is provided with control valve 3, and control valve 3 is threaded with said shaft arm through screw rod, and said screw rod stretches out the said shaft arm that is attached thereto and contacts with the medial surface of another shaft arm of said sheath handle 3, and this simplicity of design is practical.Other mode can certainly be adopted, separately getting final product of sheath pipe can be realized with the function of closure.
Angle between sheath pipe 1 and the sheath handle 2 is preferably 90-180 °, is convenient to fix.Two shaft arms of sheath handle 2 are preferably through screw rod 7 pivotal connections, and the screw rod 7 terminal operation fixtures that are fixedly connected help bimanualness under the surgical doctor scope.Two shaft arms are fulcrum with screw rod 7, through rotate control valve 3 can realize separately with near.Sheath handle 2 is preferably arc, good looking appearance.Sheath handle 2 is preferably the titanium alloy material, and sheath pipe 1 is preferably the titanium alloy material, and the titanium alloy quality is light, good toughness.When sheath pipe 1 was closed, the assembly end that nook closing member 5, sheath core 4 and sheath pipe 1 constitute was a bullet shape, can reduce the contact area with cerebral tissue, reduced normal brain tissue injury.The surface of sheath pipe 1 is provided with scale, and the accurate scale of sheath pipe is detected the cranium cerebral lesion in conjunction with extracting the sheath core in the art, or extracts nook closing member and extract hematoma, reaches the pinpoint effect of cranium cerebral lesion.
The method for using of the auxiliary sheath of adjustable nerve endoscope: at first CT or MRI scanning are carried out in cranium cephalophyma position or cerebral tumor position, tentatively confirm cranium cephalophyma or cerebral tumor position, measure the pathological changes degree of depth, and select operative approach, mini-incision.The auxiliary sheath pipe of adjustable nerve endoscope is adjusted to closure state, nook closing member 5 is packed in the sheath core 4, again the sheath core is packed in the sheath pipe 1.The auxiliary sheath of adjustable nerve endoscope is fixed; Slowly insert auxiliary sheath along operative approach; Accurate scale in conjunction with sheath pipe 1 periphery will reach the degree of depth in advance, if intracranial hematoma is taken out nook closing member; With the hollow part that syringe 6 inserts sheath core 4, extract hematoma out through syringe 6 and promptly get into the intracranial hematoma diseased region; If intracranial tumor takes out the sheath core, can be observed cerebral tumor pathological changes under the scope, so can reach the accurate location of cranium cerebral lesion.Rotate control valve, make two shaft arms of sheath handle separate through rotating regulation valve, two C shapes pipes that shaft arm drives the sheath pipe separate, and form the sheath tube passage of an inner wide and outer narrow, can enlarge the exposure range of pathological changes, expand the operation technique space of scope; Connect the operation fixture through screw rod, and insert endoscope operation, help bimanualness under the surgical doctor scope.Rotatable control valve makes the sheath pipe be in closure state after accomplishing operation technique, inserts sheath core and nook closing member, recovers the bullet-shaped of auxiliary sheath, slowly extracts auxiliary sheath, finishes operation technique.
The accurate scale of the auxiliary sheath pipe periphery of this utility model utilization reaches the degree of depth in advance, extracts nook closing member and extracts hematoma, or extract the sheath core and detect the cranium cerebral lesion, has at first reached pinpoint effect; After the cranium cerebral lesion is accurately located, rotate control valve and open the sheath pipe, form the passage of inner wide and outer narrow, so can enlarge the exposure range of pathological changes, the operation technique space of expansion scope; Connect the operation fixture through screw rod, and insert endoscopic technic, bimanualness under the surgical doctor scope, the hemostasis in the favourable Rhizoma Atractylodis Macrocephalae and the excision of pathological tissues; And, help the observation of surrounding tissue and the location in the art, thereby greatly improved safety and the effectiveness of scope in craniocerebral operations according to situation rotation sheath pipe in the art.
