Description

Double needle hole neurosurgery holder

Technical field

The present invention relates to a kind of medical operation device, particularly a kind of double needle hole neurosurgery holder, apply to the fixing of neurosurgery tissue, the tissue especially separated for two lobes.

Background technology

For neurosurgery, the operative region anatomical structure is relatively meticulous, and working place is generally narrow and small, needs corresponding meticulous apparatus to support this technology.At present in this operation, operating theater instruments still belongs to needs and studies in addition perfect situation.And be one of difficult problem for the fixing of linked groups always, there is no at present good technology and assisted.Previously mainly take the multilamellar filling as main, easily displacement and unstable, and have blindness, poor effect.

Summary of the invention

The objective of the invention is in order to overcome above deficiency, a kind of double needle hole neurosurgery holder simple in structure, easy to use is provided.

Purpose of the present invention is achieved through the following technical solutions: there is base (1) in this structure, storage nail fixing device (2), and fixed bar (3), propulsion plant (4), axle (5) and handle (6) etc. are common to be formed.There is a plane in base (1), and certain curvature is arranged.There is the orientation device of storage inside nail staple in storage nail fixing device (2).Propulsion plant (4) can promote nail.Propulsion plant (4) and handle (6) are connected by axle (5), handle (6) can be controlled propulsion plant (4), make nail (7) eject and penetrate the tissue be positioned between base (1) and storage nail fixing device (2) from storage nail fixing device (2), and the formation arcuation is fixed tissue under the effect of base (1).

The present invention compared with prior art has the following advantages: the present invention is a double needle hole neurosurgery holder, need fixing two layers of tissue, be placed between base and propulsion plant, the nail puncture promoted in it by propulsion plant sees through tissue and form arc under the effect of base, fix tissue, the present invention is simple in structure, easy to use.

the accompanying drawing explanation:

Fig. 1 is structural representation of the present invention;

Fig. 2 is the structural representation of nail;

Fig. 3 is the final form after nail is tufted into tissue;

Number in the figure: 1-base, the mono-nail of 2-propulsion plant, 3-handle.1-base, 2-storage nail fixing device, 3-fixed bar, 4-propulsion plant, 5-axle, 6-handle, 7-nail

the specific embodiment:

?in order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.

Show as shown in Figure 1, Figure 2 and Figure 3 a kind of embodiment of double needle hole neurosurgery holder of the present invention, this structure exists this structure to have base (1), storage nail fixing device (2), fixed bar (3), propulsion plant (4), axle (5) and handle (6) etc. are common to be formed.There is a plane in base (1), and certain curvature is arranged.There is the orientation device of storage inside nail staple in storage nail fixing device (2).Propulsion plant (4) can promote nail.Propulsion plant (4) and handle (6) are connected by axle (5), handle (6) can be controlled single nail propulsion plant (4), make nail (7) eject and penetrate the tissue be positioned between base (1) and storage nail fixing device (2) from storage nail fixing device (2), and the formation arcuation is fixed tissue under the effect of base (1).There is histocompatibility and follow closely (7), and finally can decompose dissipation.

The present invention is a double needle hole neurosurgery holder, needs, fixing two layers of tissue is placed between base and propulsion plant, the nail puncture promoted in it by propulsion plant sees through tissue and form arc under the effect of base, fixes tissue, and the present invention is simple in structure, easy to use.
