Description

Fiber nerve scope sheath pipe fixing device

Technical field

The utility model relates to technical field of medical instruments; The servicing unit that relates in particular to a kind of nerve endoscope ventricles of the brain operation, can be fixed on scalp, and scope sheath pipe is fixed on to the fiber nerve scope sheath pipe fixing device on support.

Background technology

Nerve endoscope has been widely used in the treatment of neurosurgery related disease, and scope is divided into hard mirror and soft lens (fiberendoscope), and fiberendoscope has been compared flexible modulation direction with hard mirror, wide-field feature. In operation, first scope sheath pipe is inserted to the ventricles of the brain, then scope is inserted to the ventricles of the brain along sheath pipe, carry out operation technique. In surgical procedure, need a hand steered sheath pipe of patient, keep for a long time a posture to make patient tired out, action distortion, the wayward sheath pipe depth, may cause sheath pipe injured brain tissue or sheath pipe to deviate from, and patient is caused damage.

Summary of the invention

The purpose of this utility model is to provide a kind of fiber nerve scope sheath pipe fixing device, can be fixed on scalp, and scope sheath pipe is fixed on its support, keeps sheath pipe not move in surgical procedure, can well protect brain tissue injury-free.

The purpose of this utility model is achieved through the following technical solutions:

A kind of fiber nerve scope sheath pipe fixing device, at nerve endoscope ventricles of the brain operation fixed support sheath pipe 1, comprising: support 2 and clamping device;

Support 2 comprises being connected to each other and is two lower support legs 21 of a font, two column plates 22 and topmast plates 23; Two lower support legs 21 are individually fixed on the scalp of operative incision two sides, and topmast plate 23 is fixed sheath pipe 1 by clamping device.

Described clamping device comprises hold-down screw 3, and the top of described topmast plate 23 is provided with sleeve pipe 24, and the side walls of sleeve pipe 24 is provided with screwed hole radially, and sheath pipe 1 is located in sleeve pipe 24, and hold-down screw 3 coordinates the sheath pipe 1 that is fixedly clamped with screwed hole.

Described hold-down screw 3 materials are rubber, plastics or stainless steel.

Described elastomeric material adopts silica gel or plastic material to adopt polytetrafluoroethylene (PTFE).

Described lower support leg 21 is provided with suture hole 211.

Described support 2 is revolving body partial structure.

The material of described support 2 is rubber, plastics or stainless steel.

Described elastomeric material adopts silica gel;

Described plastic material adopts polytetrafluoroethylene (PTFE).

The technical scheme being provided by above-mentioned the utility model can be found out; a kind of fiber nerve scope sheath pipe fixing device that the utility model embodiment provides; can be fixed on scalp; and scope sheath pipe is fixed on its support; keep sheath pipe not move in surgical procedure, can well protect brain tissue injury-free.

Brief description of the drawings

In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain other accompanying drawings according to these accompanying drawings.

The structural representation front view of the fiber nerve scope sheath pipe fixing device that Fig. 1 provides for the utility model embodiment;

The structural representation top view of the fiber nerve scope sheath pipe fixing device that Fig. 2 provides for the utility model embodiment;

The structural representation left view of the fiber nerve scope sheath pipe fixing device that Fig. 3 provides for the utility model embodiment.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment. Based on embodiment of the present utility model, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to protection domain of the present utility model.

Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.

As shown in Figures 1 and 2, a kind of fiber nerve scope sheath pipe fixing device, at nerve endoscope ventricles of the brain operation fixed support sheath pipe 1, comprising: support 2 and clamping device; Support 2 comprises being connected to each other and is two lower support legs 21 of a font, two column plates 22 and topmast plates 23; Two lower support legs 21 are individually fixed on the scalp of operative incision two sides, and topmast plate 23 is fixed sheath pipe 1 by clamping device.

Clamping device in reality can use clip etc. Clamping device described in this example comprises hold-down screw 3, and the top of described topmast plate 23 is provided with sleeve pipe 24, and the side walls of sleeve pipe 24 is provided with screwed hole radially, and sheath pipe 1 is located in sleeve pipe 24, and hold-down screw 3 coordinates the sheath pipe 1 that is fixedly clamped with screwed hole.

Because support 2 is fixed on scalp, sheath pipe 1 is fixed on support 2, can keep sheath pipe 1 not move in surgical procedure, can well protect brain tissue injury-free.

In reality, support 2 is preferably fixed on scalp, and what also can be fixed on other is fixed on other the attached object on scalp, as adhesive tape or the gauze etc. of operation use. Can be directly by leg 21 use linear slits on scalp, for the convenient suture hole 211 that is provided with on described lower support leg 21. Suture hole 211 can be multiple according to actual needs.

Meanwhile, in this example, described support 2 be revolving body partial structure on the whole, a namely circular entirety, cuts the structure of only staying middle part behind both sides, such benefit is one to economize technique and operation making the mould time, reduces costs; Two structures of carrying out revolving body may strengthen the support strength of column plate 22. Be exactly conveniently to observe the state of field of operation from the open area of two sides in addition.

Can certainly support 2 not be revolving body partial structure, be the structure of tabular bending, is also the protection domain of this patent.

Have, in this example, described elastomeric material adopts silica gel again, namely medical silica-gel, can certainly adopt other meet medical requirement as rubber, plastics or stainless steel, as polytetrafluoroethylene (PTFE).

Same hold-down screw 3 also needs to use the material that meets medical requirement, as adopted silica gel, namely medical silica-gel, can certainly adopt other meet medical requirement as rubber, plastics or stainless steel, as polytetrafluoroethylene (PTFE).

As for, the concrete size of support 2, the sheath pipe 1 and the Size dependence that during with operation, adopt are also relevant to the size of operative incision. In reality, can select voluntarily.

The above; it is only preferably detailed description of the invention of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model. Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
