Abstract
The utility model discloses the hook-shaped nerve dissector that head is designed with groove, including the handle and action bars being from top to bottom sequentially connected, the bottom end of action bars is provided with the dissecting hook for provoking ligament and soft tissue, dissecting hook is flat, and trend opens up fluted along its length on the upper surface of dissecting hook, workspace is cut for sharp knife in groove.The head is convenient, safe and reliable with the hook-shaped nerve dissector that groove is designed, and spinal cord and nerve can be protected as far as possible, while reduction operating difficulty and risk again.
Description
Technical field
The utility model belongs to technical field of medical instruments, and in particular to peeled off with the hook-shaped nerve that groove is designed on head
Son.
Background technology
The extensive use in orthopaedics, cranial surgery and general surgery of hook-shaped nerve dissector, art used in clinical at present
Middle main function is that separation appears adhesion between deep nerve tissue and ligament and soft tissue, and dural sac and nerve are retracted,
It is easy to operation technique.Common hook-shaped nerve dissector, is made up of an elongated metallic bars, including handle, action bars and hook-shaped
Head.In spinal surgery, such as anterior cervical vertebrae discectomy decompression operation is peeled off in small space domestic demand using nerve
Son is separated, and usual surgeon's left hand holds nerve dissector middle part, with hook-shaped head blunt separation and provokes posterior longitudinal ligament
With surrounding soft tissue, the right hand holds sharp knife and posterior longitudinal ligament completion decompression is cut above dural sac.However, because operating space has
Limit, while posterior longitudinal ligament is provoked using nerve dissector, also needs to cut ligament and soft tissue on dural sac surface with sharp knife,
It is careless slightly will result in dural sac damage cause serious consequence.
Utility model content
The purpose of this utility model is the not enough, peace easy to use in art there is provided one kind for being directed to existing nerve dissector
It is complete reliable, spinal cord and nerve can be protected as far as possible, while the hook that the head of reduction operating difficulty and risk is designed with groove again
Shape nerve dissector.
In order to solve the above technical problems, the technical solution adopted in the utility model is：The hook-shaped god that head is designed with groove
Stripped son, including the handle and action bars being from top to bottom sequentially connected, the bottom end of action bars are provided with tough for provoking
The dissecting hook of band and soft tissue, dissecting hook is that trend opens up fluted along its length in flat, and the upper surface of dissecting hook, recessed
In groove workspace is cut for sharp knife.
Further, the front end of the dissecting hook is tilted towards action bars, and is 85 ° with the angle of action bars.
Further, the junction of the upper and lower surface of the dissecting hook is the smooth arc-shaped surface of evagination.
The utility model head has the following advantages that with the hook-shaped nerve dissector that groove is designed：1. dissecting hook is designed as flat
It is flat-shaped, it is easy to be embedded in ligament and soft tissue in narrow and small operative space, completes the blunt separation between shallow-layer and deep tissues；2. stripping
Trend opens up fluted meter along its length on off-hook upper surface, cuts ligament and soft tissue downwards available for support sharp knife, makes point
Knife limits the depth and scope of operation in groove internal cutting, it is to avoid the sharp instrument such as application sharp knife carries out damaging deep during cutting operation
The risk of tissue；3. evagination and it is smoothly connected between the upper and lower surface of the dissecting hook of elevator, it is to avoid in surgical procedure
Injure peripheral vessels and nerve.
Brief description of the drawings
Fig. 1 is the structural representation for the hook-shaped nerve dissector that the utility model head is designed with groove.
Fig. 2 is the structural representation of the dissecting hook in the utility model；
Wherein：1. handle；2. action bars；3. dissecting hook；3-1. groove.
Embodiment
As shown in figure 1, the hook-shaped nerve dissector that the utility model head is designed with groove, including from top to bottom connect successively
The handle 1 and action bars 2 connect, the bottom end of action bars 2 is provided with the dissecting hook 3 for provoking ligament and soft tissue.
As shown in Fig. 2 dissecting hook 3 is that trend opens up fluted 3- along its length in flat, and the upper surface of dissecting hook 3
In 1, groove 3-1 workspace is cut for sharp knife.
When in use, doctor's hand-held handle provokes ligament and soft tissue to the utility model using dissecting hook 3, and by groove
As cutting workspace in 3-1, cuts ligament and soft tissue downwards with sharp knife, be easy to narrow and small operative space be embedded in ligament and
Soft tissue, completes the blunt separation between shallow-layer and deep tissues；The depth and scope of operation are limited in groove 3-1, it is to avoid should
Carry out damaging the risk of deep tissue with sharp instruments such as sharp knives during cutting operation.Meanwhile, ligament and soft tissue are cut downwards in sharp knife
Shi Zuowei is protected, it is to avoid injure surrounding tissue.
In the hook-shaped nerve dissector that the utility model head is designed with groove, the front end of dissecting hook 3 is inclined towards action bars 2
Tiltedly, and with the angle of action bars 2 it is 85 °, it is easy to embedded and provoke ligament and soft tissue upwards, and separated.Dissecting hook 3
The junction of upper and lower surface is the smooth arc-shaped surface of evagination, it is to avoid peripheral vessels and nerve are injured in surgical procedure.
Claims (2)
1. the hook-shaped nerve dissector that head is designed with groove, it is characterised in that including the handle (1) being from top to bottom sequentially connected
With action bars (2), the bottom end of the action bars (2) is provided with the dissecting hook (3) for provoking ligament and soft tissue, described
Dissecting hook (3) is that trend is opened up fluted (3-1) along its length in flat, and the upper surface of the dissecting hook (3), described recessed
In groove (3-1) workspace is cut for sharp knife；The front end of the dissecting hook (3) towards action bars (2) tilt, and with action bars (2)
Angle be 85 °.
2. according to the nerve dissector described in claim 1, it is characterised in that the upper and lower surface of the dissecting hook (3)
Junction be evagination smooth arc-shaped surface.
