Abstract
The utility model relates to the medical instruments, in particular to a microscopic scalpel for transsphenoidal surgery. The microscopic scalpel for transsphenoidal surgery comprises a handle in a straight shape. The microscopic scalpel for transsphenoidal surgery is characterized in that a bent rod in an arc shape is fixed to the right end of the handle, an extension rod in the straight shape is fixed to the right end of the bent rod, and a blade in a crescent shape is fixed to the right end of the extension rod. The microscopic scalpel for transsphenoidal surgery is applicable to effectively cutting nasal septum mucosa, sphenoidal sinus mucosa and sellar dura, is convenient to operate and is high in accuracy.
Description
Technical field
This utility model relates to medical apparatus and instruments, especially relates to a kind of transsphenoidal surgery micro-bistoury.
Background technology
Trans-nasal-sphenoidal approach is the operative approach of neurosurgery and department of otorhinolaryngology routine.Operation technique through this approach all carries out to this pathway of sphenoid sinus by nasal cavity, needs to cut dura mater at the bottom of nasal septal membrane, mucous membrane of sphenoid sinus and saddle in operation process.How at nasal cavity to dura mater at the bottom of using micro-bistoury to cut smoothly nasal septal membrane, mucous membrane of sphenoid sinus and saddle in this narrow space of sphenoid sinus, and keep its integrity, be to ensure operation smoothly, the key point of Postoperative reconstruction and anatomical reduction, is also the difficult point of operation.
At present, adopt clinically little dise knife, arachnoid knife and electric knife etc. to complete aforesaid operations, but all have obvious shortcoming.Little dise knife is straight-bar scalpel, in operating process, sometimes can not under direct-view, carry out, and operation accuracy is poor, and because operative space is little, block vision under microscope, is used the normal operation of little dise knife very inconvenient; Arachnoid knife easily punctures mucosa and dura mater, but because arachnoid knife is that the mode that adopts hook to drag is cut mucosa or dura mater, length, the direction etc. of otch is all difficult to accurately control, and mucous membrane of sphenoid sinus is close to sphenoid sinus rear wall sclerotin, and the hook that affects arachnoid knife is dragged operation; Electric knife, because easily causing the shrinkage of mucosa and dura mater in its incision process, affect Postoperative reconstruction, and under microscope, electric knife volume is large, stops the visual field, also limits its use clinically.There is no clinically at present the special-purpose surgical knife that is applicable to transnaso-sphenoidal approach band base of a fruit mucosa reconstruction operations.
Summary of the invention
The purpose of this utility model is to provide a kind of safety clinically, effectively cuts dura mater at the bottom of nasal septal membrane, mucous membrane of sphenoid sinus and saddle, the transnaso-sphenoidal approach micro-bistoury that easy to operate, accuracy is strong.
The purpose of this utility model is achieved in that
A kind of transsphenoidal surgery micro-bistoury, comprises the handle of vertical bar shaped, and feature is: be fixed with the bent stick of arc at the right-hand member of handle, be fixed with the extension rod of vertical bar shaped at the right-hand member of bent stick, be fixed with meniscate cutter hub at the right-hand member of extension rod.
The convex surface part of described cutter hub and concave surface portion are blade, and the end of cutter hub is sharp.
The left end of bent stick and handle angle is in the horizontal direction 125-130 degree, and the left end of cutter hub and extension rod angle is in the horizontal direction 10--15 degree.
Be processed with anti-skidding wear-resisting lines in the lateral wall of handle.
Handle, bent stick, extension rod and cutter hub are real core.
This utility model is made up of the handle being connected as a single entity, bent stick, extension rod and cutter hub; and cutter hub is upper and lower twolip all; and the end of cutter hub is sharp; the hand-holdable handle of operator; utilizing bent stick to reach and avoid the hands of holding handle in art to block surgical field of view, enter nasal cavity by extension rod and carry out operation technique (length of extension rod is for being longer than the average nasal cavity degree of depth of this country). nasal septal membrane and mucous membrane of sphenoid sinus can cut by the convex surface part of cutter hub; At the bottom of saddle, dura mater can first puncture with the sharp property of cutter hub tip, then cuts with the concave surface portion of cutter hub, solved cannot facilitate clinically at present, safe, the problem of effectively cutting dura mater at the bottom of nasal septal membrane, mucous membrane of sphenoid sinus and saddle.
This utility model is compared to prior art, has following beneficial effect:
1. easy to operate, accuracy is strong, is difficult for accidentally injuring surrounding tissue.
2. mucosa and not shrinkage of dura mater after cutting, postoperative mucosa and dura mater can anatomical reductions.
3. sterilization is convenient.
4. cheap.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with embodiment and contrast accompanying drawing this utility model is described in further detail.
A kind of transsphenoidal surgery micro-bistoury, comprises the handle 1 of vertical bar shaped, is fixed with the bent stick 2 of arc at the right-hand member of handle 1, is fixed with the extension rod 3 of vertical bar shaped at the right-hand member of bent stick 2, is fixed with meniscate cutter hub 4 at the right-hand member of extension rod 3.
The convex surface part of described cutter hub 4 and concave surface portion are blade, and the end of cutter hub 4 is sharp.
The left end of bent stick 2 and handle 1 angle α is in the horizontal direction 125-130 degree, and the left end of cutter hub 4 and extension rod 3 angle β is in the horizontal direction 10--15 degree.
Be processed with anti-skidding wear-resisting lines 5 in the lateral wall of handle 1.
Handle 1, bent stick 2, extension rod 3 and cutter hub 4 are real core.
The length of handle 1 is about 8cm, diameter 5mm; The about 1.5cm of horizontal length, the diameter 3mm of bent stick 2, the left end of bent stick 2 and handle 1 angle α is in the horizontal direction 125-130 degree; The about 10cm of length, the diameter 2mm of extension rod 3; The about 0.5cm of length of cutter hub 4, left end and the extension rod 3 angle β in the horizontal direction that the widest portion diameter is about 1mm, cutter hub 4 are 10--15 degree.
