Abstract
A surgical suturing instrument with electroactive polymers comprises a handle. The handle is provided with a mounting cavity inside. An opening of the mounting cavity is located in an end of the handle and is sealed via a seal plate. The electroactive polymers are disposed in the mounting cavity. One end of the electroactive polymers is connected to the bottom of the mounting cavity. The end of the electroactive polymers far away from the bottom of the mounting cavity is provided with a suturing needle. The suturing needle is exposed out of the seal plate through a through hole arranged in the seal plate. Two symmetrical electrode plates are embedded in the sidewall of the mounting cavity. The electroactive polymers in the surgical suturing instrument may have great deformation and elasticity under the action of electric field, so that the surgical suturing instrument controls the deformation of the electroactive polymers through changes in the electric field; the suturing needle flexes at the end of the handle, manually using a needle holder to clamp the suturing needle is not required, suturing precision is improved, and work is easier for medical staff.
Description
Technical field
The present invention relates to surgical stapling device technical field, be specially one and there is electroactive polymer surgical stapling device.
Background technology
At present, clinically when carrying out surgical operation suturing to patient, mostly need to use needle forceps to the sewing needle that is fixedly clamped, then needle forceps is sewed up, operate like this and extremely bother, waste time and energy, add great work difficulty to medical worker, for this reason, we propose one and have electroactive polymer surgical stapling device.
Summary of the invention
One is the object of the present invention is to provide to have electroactive polymer surgical stapling device, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
One has electroactive polymer surgical stapling device, comprise hands handle, installation cavity is provided with in handle, the opening of installation cavity is positioned at the end of handle and is sealed by sealing plate, electroactive polymer is provided with in installation cavity, one end of electroactive polymer is connected to the bottom surface of installation cavity, electroactive polymer installs sewing needle away from one end of installation cavity bottom surface, sewing needle is exposed outside sealing plate by the through hole be arranged on sealing plate, the sidewall of installation cavity is inlayed two symmetrical battery lead plates, and electroactive polymer is between two battery lead plates, during use, two battery lead plate energisings produce electric field, make electroactive polymer flexible under the effect of electric field.
Preferably, handle is pyramidal structure near one end of sewing needle, and the conical surface of handle is provided with soft rubber layer.
Preferably, the sidewall of handle connects storage line roller by pole, the sewing line on storage line roller is through on sewing needle.
Preferably, when electroactive polymer is in the longest, electroactive polymer and sealing plate contact and sewing needle are stretched out completely.
Compared with prior art, the invention has the beneficial effects as follows: this electroactive polymer had in electroactive polymer surgical stapling device can produce great deformation and elasticity under electric field action, so this surgical stapling device controls the deformation of electroactive polymer by the change of electric field, make sewing needle flexible in the end of handle, thus without the need to manually using needle forceps to be clamped by sewing needle, improve stitching precision, alleviate the work difficulty of medical worker.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1 handle, 2 poles, 3 installation cavitys, 4 sealing plates, 5 electroactive polymers, 6 sewing needles, 7 battery lead plates, 8 storage line rollers.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the invention provides a kind of technical scheme: one has electroactive polymer surgical stapling device, comprise handle 1, handle 1 is pyramidal structure near one end of sewing needle 6, and the conical surface of handle 1 is provided with soft rubber layer, be provided with installation cavity 3 in handle 1, the opening of installation cavity 3 is positioned at the end of handle 1 and is sealed by sealing plate 4.
Electroactive polymer 5 is provided with in installation cavity 3, one end of electroactive polymer 5 is connected to the bottom surface of installation cavity 3, electroactive polymer 5 installs sewing needle 6 away from one end of installation cavity 3 bottom surface, sewing needle 6 is exposed outside sealing plate 4 by the through hole be arranged on sealing plate 4, the sidewall of installation cavity 3 is inlayed two symmetrical battery lead plates 7, and electroactive polymer 5 is between two battery lead plates 7, during use, two battery lead plates 7 are energized and produce electric field, make electroactive polymer 5 flexible under the effect of electric field, when electroactive polymer 5 is in the longest, electroactive polymer 5 contacts with sealing plate 4 and sewing needle 6 is stretched out completely, the sidewall of handle 1 connects storage line roller 8 by pole 2, sewing line on storage line roller 8 is through on sewing needle 6.
This electroactive polymer 5 had in electroactive polymer surgical stapling device can produce great deformation and elasticity under electric field action, so this surgical stapling device controls the deformation of electroactive polymer 5 by the change of electric field, make stitching 6 flexible in the end of handle 1, thus without the need to manually using needle forceps to be clamped by sewing needle 6, improve stitching precision, alleviate the work difficulty of medical worker.
Although illustrate and describe embodiments of the invention, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments without departing from the principles and spirit of the present invention, scope of the present invention is by claims and equivalents thereof.
