Abstract
The utility model discloses a visual nerve endoscopic guide sheath, comprising a guide sheath head, a sheath tube, a sheath core, a telescopic boom, a positioning bolt and a fastener; the utility model is characterized in that the guide sheath head and the sheath core are arranged in the guide sheath tube; a slide bushing is sleeved on the guide sheath tube; the positioning bolt is arranged on the slide bushing; the fastener is arranged at the tail end of the sheath core. The visual nerve endoscopic guide sheath has the advantages that in the inspection of the operator, the guide sheath is leaded into the skull of the patient, so the operator can determine the precise location of intracranial hematoma; then the guide sheath helps a neuroendoscope or a broken hematoma aspirator to clean and remove the intracranial hematoma.
Description
Technical field
This utility model relates to a kind of medical scope lead sheath, particularly a kind of nerve endoscope lead sheath.
Background technology
At present, general intracranial hematoma puncture aspiration drainage art, earlier in the corresponding lesions position boring of skull, according to the hematoma degree of depth perforator is slowly stretched into the intracranial hematoma place by the skull hole then, after puncture tube is positioned at the depth sounding position, plug is extracted out, the intracranial hematoma crushing aspirating device is stretched into carry out the broken suction operation of hematoma in the puncture tube again.Because the plug of perforator is bar-shaped solid, in the process in perforator stretches into, operator can't judge the accurate position of hematoma, can only be by apparatus indirect observation and monitoring such as CT, so its effect is unsatisfactory.
Summary of the invention
The purpose of this utility model is to overcome the weak point of above-mentioned existing puncture instrument, and a kind of scope lead sheath that can carry out ventricular puncture under operator are visual is provided.
For the solution that realizes this utility model purpose as follows: this visual scope lead sheath comprises transparent sheath pipe, it is characterized in that having in the transparent sheath pipe transparent flow line style lead sheath head, the lead sheath head is connected with the sheath core, the lead sheath head is fixed on the scope head by sheath core and fastener, or adopts to be threaded the lead sheath head is fixed on the scope head.
As further specifying of such scheme, described sheath core end has a fastener, and the sheath core is fixed in the scope head by fastener.
Described sheath pipe is with a sliding sleeve outward, and a location screw is arranged on the sliding sleeve.
Described transparent lead sheath head also can be fastened on the scope head with the lead sheath head by being threaded.
The utility model has the advantages that because a transparent flow line style lead sheath head arranged in transparent sheath pipe, thereby can puncture to the ventricles of the brain down, can accurately judge the degree of depth of intracranial hematoma, be convenient to carry out the intracranial hematoma clearance operation the visual of operator.
Description of drawings
Below in conjunction with accompanying drawing this utility model is elaborated,
Fig. 1 is the broken section structural representation of the visual scope lead sheath of this utility model.
Description of reference numerals: lead sheath head 1, sheath pipe 2, sheath core 3, sliding sleeve 4, dog screw 5, fastener 6
The specific embodiment
As shown in Figure 1, visual scope lead sheath comprises transparent sheath pipe 2, one transparent flow line style lead sheath head 1 is arranged in the transparent sheath pipe 2, lead sheath head 1 is connected with sheath core 3, lead sheath head 1 is fastened in the scope head, wherein, lead sheath head 1 and sheath core 3 fixedly be that a fastener 6 by sheath core 3 ends is fixed on the scope head, outside the sheath pipe, be with a sliding sleeve 4, a location screw 5 is arranged on the sliding sleeve 4; Described transparent lead sheath head 1 also can be fastened on the scope head with lead sheath head 1 by being threaded.
The sheath core 3 that will be connected with the lead sheath head earlier during use passes the service aisle of nerve endoscope or hematoma crushing aspirating device, end at scope, utilize fastener 6 to clamp sheath core 3, lead sheath head 1 is fastened on the scope head, or adopt to be threaded the lead sheath head is fastened on the scope head, then lead sheath head 1 is stretched in the sheath pipe 2 together with scope, stretch into Intraventricular simultaneously, operator utilize visor and transparent lead sheath head 1 and sheath pipe 2, the situation of intracranial in the energy direct observation lead sheath depth sounding process, thereby exactly lead sheath and visor are stretched to the hematoma position of intracranial, utilize dog screw 5 to be fixed on the depth sounding position of sheath pipe 2 sliding sleeve on the sheath pipe 24, then lead sheath head 1 and scope are extracted, will lead fastener 6, sheath head 1 and sheath core 3 unload, then, nerve endoscope or hematoma crushing aspirating device are stretched into sheath pipe 2 and can carry out the hematoma clearance operation.
