Background technology
In the middle of minimally invasive spinal surgery operation, nerve hook, suction pump and light source are all absolutely necessary operating equipment, and frequency of utilization is higher.Wicresoft's theory that wound is little, wound is micro-, must cause the limitation in operation technique space.In narrow and small Wicresoft's passage, frequently change operating theater instruments, all bring some harmful effects to the process of operation, the operation technique of doctor and postoperative effect, it shows:
1. frequently change apparatus, increase and infect possibility;
2. special messenger's drag hook attracts, and increases human load;
3. more than people operating apparatus, increases cooperation difficulty;
4. interference operator operation, increases possibility of makeing mistakes;
5. open light source passage, increase surgical wound;
6. to grow blood many time, affect postoperative effect.
Utility model content
The purpose of this utility model is to provide a kind of Multifunctional nerve retractor, to solve the operation risk carrying out the instability that operation technique brings, reduces operating time and amount of bleeding, reduce and infect possibility, reduce the intervention of apparatus in visual area, improve overall operation quality, improve postoperative effect.
The purpose of this utility model realizes like this, a kind of Multifunctional nerve retractor, it is characterized in that: comprise the hand holding handle on nerve hook body and nerve hook body, nerve hook body is into the hollow barred body shape at 90o angle, wherein vertical hollow barred body has a light source passage in parallel, vertical hollow barred body is attraction channel, and light source passage is shorter than attraction channel, and light source passage length is less than or equal to the vertical hollow barred body of 1/2nd; The lower end internal orifice of attraction channel is angular cut, and inclined-plane forward; On rear side of angular cut mouth wall, 90o has extended back drag hook groove; There is inclined-plane projection the lower internal orifice outlet below of light source passage, and the upper collar extension of light source passage is positioned at the 90o turning point of nerve hook body, and light source thus entrance enters light source passage; The horizontal hollow barred body socket hand holding handle of described nerve hook body, the 90o of hand holding handle and nerve hook body bends centre the recessed dish of the circle of a middle opening, and the middle opening of the recessed dish of circle of middle opening communicates with attraction channel.
The rear end collar extension of described hand holding handle is attraction channel entrance, connects with negtive-pressure implement.
Described light source passage lower end internal orifice is high compared with internal orifice position, attraction channel lower end, bore is large.
The utility model has the advantages that: there is features such as " multifunctional integrated; appeal is adjustable; light source directive is adjustable; the assembly of drag hook specification is various; to be suitable for individuation and to select ", can accomplish to carry out controllability illumination to operation operating area in limited space, carry out drawing simultaneously, attraction operation do not interfere with each other, reduce possibility of makeing mistakes; Without the need to additional light source passage, reduce unnecessary wound; Alleviate assistant's load, liberation medical worker labour force, thus solve many people and operate the large problem of the cooperation difficulty brought; Simple to operate, without the need to frequently changing use apparatus, simplify the operating procedure of whole operation process, reduce the operation risk that patient attracts to carry out on the other hand the fluctuation of service that operation technique brings on the other hand, reduce operating time and amount of bleeding, reduce and infect possibility, improve overall operation quality, improve postoperative effect.
Accompanying drawing explanation
Below in conjunction with embodiment accompanying drawing, the utility model is described in further detail:
Fig. 1 is this utility model embodiment 1 structural representation:
In figure, 1, nerve hook body; 2, hand holding handle; 3, vertical hollow barred body; 4, light source passage; 5, lower end internal orifice; 6, drag hook groove; 7, lower internal orifice outlet; 8, inclined-plane projection; 9, upper collar extension; 10, horizontal hollow barred body; 11, the recessed dish of the circle of middle opening; 12, middle opening; 13, rear end collar extension; 14, negtive-pressure implement.
Detailed description of the invention
As shown in Figure 1, a kind of Multifunctional nerve retractor, comprise the hand holding handle 2 on nerve hook body and nerve hook body 1, nerve hook body 1 is into the hollow barred body shape at 90o angle, wherein vertical hollow barred body 3 has a light source passage 4 in parallel, vertical hollow barred body 3 is attraction channel, and light source passage is shorter than attraction channel, and light source passage 4 length is less than or equal to the vertical hollow barred body 3 of 1/2nd; The lower end internal orifice 5 of attraction channel is angular cut, and inclined-plane forward; On rear side of angular cut mouth wall, 90o has extended back drag hook groove 6, can play traction action to nerve root and spinal dura mater; Drag hook groove 6 width specifications can be selected according to the difference of traction thing; Light source passage 4 lower end internal orifice is high compared with internal orifice 5 position, attraction channel lower end, bore large, has inclined-plane projection 8, play the effect regulating light source directive below the lower internal orifice outlet 7 of light source passage 4; The upper collar extension 9 of light source passage 4 is positioned at the 90o turning point of nerve hook body 1, and light source thus entrance enters light source passage 4; The horizontal hollow barred body 10 of described nerve hook body 1 is socketed hand holding handle 2, the recessed dish 11 of the circle of a middle opening is had in the middle of hand holding handle 2 and the 90o of nerve hook body 1 bend, the middle opening 12 of the recessed dish 11 of circle of middle opening communicates with attraction channel, plays the effect regulating appeal; The rear end collar extension 13 of hand holding handle 2 is attraction channel entrances, connects with negtive-pressure implement 14.
Work process of the present utility model is:
After posterior spinal operation appears, fully expose and protect spinal cord dura mater and nerve root, apply the protection of this integral multifunctional nerve hook and retract nerve to midspinal line, appearing the intervertebral disc needing row excision.By the intercalated disc of suction pump angle towards required process, by the circle of handle end recessed dish regulation and control suction pump suction size, ensure that surgical field of view is clear.From light source passage top end opening, vertebral column minimally invasive passage cold light source probe is inserted in passage, according to the position of visual area, by the gradient adjustment light source irradiation scope of light source passage lower ending opening, ensure that visual area light illumination is clear.After conventional method processes reconstruction of nucleus gelatinosus tissue; perform the operation as needed row Intervertebral fusion; also need under the protection of nerve hook; the cartilage endplate of the instrument process intervertebral disc such as application curet; for bone-graft fusion creates conditions; finally under the protection of nerve hook, fusion device device or autologous/allograph bone need be implanted between vertebral body.The processes such as regular posterior spinal operation decompression and Interbody fusion, all need to apply drag hook.
In addition, in art, we need to select the degree of depth of drag hook body and the width of drag hook groove, to ensure best surgical effect according to the different operative sites of patient, sub-dermal soft tissue thickness, nerve factors such as size of windowing.
The parts that the present embodiment does not describe in detail and structure belong to the well-known components of the industry and common structure or conventional means, do not describe one by one here.
