Described driving device contains cylindrical iron block, electric magnet, DC source and driving device shell etc., and cylindrical iron block is fixed on connection rope, and electric magnet produces magnetic in energising situation, attracts cylindrical iron block to be subjected to displacement by magneticaction.
The front end of this novel microscopic needle holder belongs to tweezer class, and sensitivity and the degree of control of strength are better than pincers class by tweezer core, and the dexterity of its operation is also better than pincers class, can be applied to precision, micro-occasion more, is particularly suited for the operation such as cardiovascular surgery, microsurgery.
The present invention compared with prior art has the advantage that
1, clamping aspect, under spring effect, chucking power is uniform, it is to avoid the artificial force excessive sewing needle pinch off caused；The front end opening and closing holding pin tweezer core is flexible, and has good elasticity and clamping steadiness.
2, operating aspect, this novel microscopic needle holder is normally closed type, rear end driving act on connection rope and realize holding the folding of pin tweezer core front end, save the manual control action of operator, simple to operate, it is easy to control.
3, become present aspect, be threaded connection and be fixed on the accurate operating robot front end of micro-behaviour, thus reducing overall operation apparatus cost.
Accompanying drawing explanation
Fig. 1 is the appearance structure sketch of the present invention.
Fig. 2 is the internal structure sketch of the present invention.
Detailed description of the invention
In structure diagram shown in Fig. 1 and Fig. 2, this novel microscopic needle holder is made up of parts such as holding pin tweezer core 1, cervical region 2, adapter sleeve 3, the collar 4, outer tube 5, driving device 6, compression spring 7, alignment pin 8, connection rope 9, wherein, driving device contains cylindrical iron block 10, electric magnet 11, DC source 12 and driving device shell 13 etc..This novel microscopic needle holder is normally closed type, the cylindrical iron block 10 of driving device is fixed on connection rope 9, electric magnet 11 produces magnetic in energising situation, cylindrical iron block 10 is attracted to be subjected to displacement by magneticaction, acted on connection rope 9 realization by driving device and hold opening of pin tweezer core 1 front end, save the manual control action of operator.Simple to operate, it is easy to control, opening and closing is flexible, and has good elasticity and clamping steadiness.
Holding the single curved tweezer pattern of front end employing of pin tweezer core 1, after Guan Bi, thickness is 1.5mm～2.0mm, and angle of bend is 130 °, and bent tip length is 2.0mm～3.0mm, is conducive to sewing up the knotting of operation and stitching thread, it is simple to consolidate and hold pin and do not hide surgical field of view；The rear end holding pin tweezer core is connected by alignment pin 8, is fixed on adapter sleeve 3.
