Abstract
The utility model relates to a working sheath, in particular to a working sheath of a nerve endoscope, which belongs to the technical field of medical apparatuses. The working sheath comprises a transparent sheath tube. One end of the transparent sheath tube is provided with a sheath guide head, and the other end is fixed and connected with a fixing sleeve head. A sheath core is arranged in the transparent sheath tube, one end of the sheath core is provided with an end cover, and the other end is provided with a positioning sleeve tube. The end of the sheath core, provided with the end cover, extends into the transparent sheath tube. The sheath core is in interference fit with the transparent sheath tube. By arranging the fixing sleeve head at the end of the sheath tube, the working sheath of the nerve endoscope is effectively fixed in the nerve endoscope operation process, and then the assistance provided by operation assistants is not needed. The sheath tube and the sheath core are respectively made from transparent hard plastic, so the entering depth of the working sheath can be accurately judged, and the condition of the stoma channel of brain tissue cortex around the working sheath can be clearly judged. The working sheath is convenient to operate in the nerve endoscope operation process.
Description
Technical field
This utility model relates to a kind of work sheath, and especially a kind of nerve endoscope work sheath belongs to technical field of medical.
Background technology
At present, the tube that often uses nerve endoscope work sheath to adopt opaque metal to make uses perhaps that transparent plastic hose is simple and easy to form more.In the nerve endoscope operation, the operating walk way of Chang Zuowei nerve endoscope operation.But but the nerve endoscope work sheath that uses does not at present often have stationarity, need assistant's mate-assist in the operation, and can't accurately judge the degree of depth that enters of the sheath of working in the art, but have also do not have a perspectivity, operation brings certain difficulty and inconvenience to nerve endoscope.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of nerve endoscope work sheath is provided, and it is simple in structure, easy to use.
According to the technical scheme that this utility model provides, described nerve endoscope work sheath comprises the clear sheath pipe; One end of described clear sheath pipe is provided with the lead sheath head, and the other end is provided with fixedly connected fixing pullover; Be provided with the sheath core in the described clear sheath pipe, an end of described sheath core is provided with end cap, the other end be provided with the location pullover, described sheath core stretches in the clear sheath pipe corresponding to the end that is provided with end cap, described sheath core cooperates with the clear sheath ligament.
Adopt arc transition between the body of described sheath pipe and lead sheath head.Described end cap is an arc structure.Described fixing pulloverly make by rustless steel or rigid plastics.Described sheath core) adopt rustless steel or rigid plastics to make.Described clear sheath pipe is made by transparent rigid plastics.Described rigid plastics comprises vinyon.
Advantage of the present utility model: be provided with fixing pulloverly by the end at the sheath pipe, in the nerve endoscope operation process, it is effectively fixing that nerve endoscope work sheath is obtained, and need not the auxiliary of assistant.Described sheath pipe and sheath core all adopt transparent rigid plastics to make, accurately the judgment task sheath enter the degree of depth, situation that simultaneously can clear judgment task sheath surrouding brain tissue cortex fistulation passage, easy to operate in the nerve endoscope operation process.

Fig. 2 is a sheath tubular construction sketch map of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As Fig. 1～shown in Figure 2: this utility model comprises that the location is pullover 1, sheath core 2, fixing pullover 3, clear sheath pipe 4, end cap 5 and lead sheath head 6.
As depicted in figs. 1 and 2: an end of described sheath core 2 is provided with that the location is pullover 1, and the other end is provided with end cap 5, and described end cap 5 adopts arc structures.Described sheath core 2 stretches in the clear sheath pipe 4 corresponding to the end that end cap 5 is set, described sheath core 2 and clear sheath pipe 4 matched in clearance.One end of described clear sheath pipe 4 is provided with lead sheath head 6, and the other end is provided with fixing pullover 3; 4 of described lead sheath head 6 and clear sheath pipes adopt arc transition, and described fixing pullover 3 adopt rustless steel or rigid plastics to make, and are used for fixing whole clear sheath pipe 4.Described clear sheath pipe 4 adopts transparent rigid plastics to make, the plastics of described hard comprise vinyon, can observe the degree of depth that clear sheath pipe 4 inserts when clear sheath pipe 4 inserts the cerebral tissue cortex with sheath core 2, described sheath core 2 adopts rustless steel or rigid plastics to make.Also marking on the tube wall of described clear sheath pipe 4 has a millimeter unit scale, can accurately locate the degree of depth that needs insertion.
As depicted in figs. 1 and 2: during use, sheath core 2 is inserted in the clear sheath pipe 4, by the degree of depth that location pullover 1 determines that sheath core 2 inserts in the clear sheath pipe 4 is set in sheath core 2 ends, sheath core 2 adopts matched in clearance with clear sheath pipe 4, be convenient to take out sheath core 2, go into neural endoscopic surgery apparatus in clear sheath pipe 4 interpolations simultaneously.In the nerve endoscope operation process, sheath core 2 is inserted the cerebral tissue cortex with clear sheath pipe 4 make the flaccidity mouth gradually deeply to operating position, then sheath core 2 is taken out, fixing pullover 3 and fixation clamp with clear sheath pipe 4 ends fixes again, snakelike retractor commonly used in described fixation clamp and the neurosurgery fixes, and reaches the fixedly purpose of clear sheath pipe 4.
This utility model is simple in structure, by make at clear sheath pipe 4 end rustless steels or rigid plastics fixing pullover 3 with the corresponding cooperation of snakelike retractor, can be in nerve endoscope work operation fixing clear sheath pipe 4.Sheath core 2 adopts stainless steel material or rigid plastics to make simultaneously, guarantees that clear sheath pipe 4 inserts the hardness of cerebral tissue.On the tube wall of clear sheath pipe 4, scale is set, can accurately locatees the degree of depth that clear sheath pipe 4 inserts, easy to use, safe and reliable.
