Abstract
One kind has electroactive polymer surgical stapling device, including handle, the interior of handle is equipped with installation cavity, the opening of installation cavity is sealed positioned at the end of handle and by sealing plate, electroactive polymer is equipped with installation cavity, one end of electroactive polymer is connected to the bottom surface of installation cavity, one end installation sewing needle of the electroactive polymer away from installation cavity bottom surface, sewing needle is exposed on the outside of sealing plate by the through hole being arranged on sealing plate, and two symmetrical electrode plates are inlayed on the side wall of installation cavity.This can produce great deformation and elasticity with the electroactive polymer in electroactive polymer surgical stapling device under electric field action, so the surgical stapling device controls the deformation of electroactive polymer by the change of electric field, so that sewing needle stretches in the end of handle, without manually sewing needle is clamped using needle forceps, suture precision is improved, alleviates the work difficulty of medical worker.
Description
Technical field
The present invention relates to surgical stapling device technical field, is specially that one kind has electroactive polymer surgical stapling device.
Background technology
At present, clinically needed mostly using needle forceps come the seam that is fixedly clamped when carrying out surgical operation suturing to patient
Pin is closed, then needle forceps is sutured, so operates cumbersome, time-consuming and laborious, is added greatly to medical worker
Work difficulty, for this reason, it is proposed that a kind of have electroactive polymer surgical stapling device.
The content of the invention
It is an object of the invention to provide one kind to have electroactive polymer surgical stapling device, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the present invention provides following technical solution：
One kind has electroactive polymer surgical stapling device, including handle, and the interior of handle is equipped with installation cavity, and installation cavity is opened
Mouth is sealed positioned at the end of handle and by sealing plate, and electroactive polymer, one end of electroactive polymer are equipped with installation cavity
The bottom surface of installation cavity, one end installation sewing needle of the electroactive polymer away from installation cavity bottom surface are connected to, sewing needle passes through setting
Through hole on sealing plate is exposed on the outside of sealing plate, two symmetrical electrode plates is inlayed on the side wall of installation cavity, and electricity is living
Fluidized polymer is between two electrode plates, in use, two electrode plates are powered and produce electric field so that electroactive polymer is in electricity
Stretch under the action of.
Preferably, handle is pyramidal structure close to one end of sewing needle, and the conical surface of handle is equipped with soft rubber layer.
Preferably, storage line roller is connected by strut on the side wall of handle, the sewing line on storage line roller is through sewing needle
On.
Preferably, when electroactive polymer is in most long, electroactive polymer is contacted with sealing plate so that sewing needle is complete
Stretch out.
Compared with prior art, the beneficial effects of the invention are as follows：This is with the electricity in electroactive polymer surgical stapling device
Activated polymer can produce great deformation and elasticity under electric field action, thus the surgical stapling device by the change of electric field come
Control the deformation of electroactive polymer so that sewing needle stretches in the end of handle, without will manually be stitched using needle forceps
Close pin to clamp, improve suture precision, alleviate the work difficulty of medical worker.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure：1 handle, 2 struts, 3 installation cavitys, 4 sealing plates, 5 electroactive polymers, 6 sewing needles, 7 electrode plates, 8 storage lines
Roller.
Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment, belongs to the scope of protection of the invention.
Referring to Fig. 1, the present invention provides a kind of technical solution：One kind has electroactive polymer surgical stapling device, including
Handle 1, handle 1 is pyramidal structure close to one end of sewing needle 6, and the conical surface of handle 1 is equipped with soft rubber layer, handle 1
It is interior be equipped with installation cavity 3, the opening of installation cavity 3 is sealed positioned at the end of handle 1 and by sealing plate 4.
Electroactive polymer 5 is equipped with installation cavity 3, one end of electroactive polymer 5 is connected to the bottom surface of installation cavity 3, electricity
One end installation sewing needle 6 of the activated polymer 5 away from 3 bottom surface of installation cavity, sewing needle 6 pass through the through hole that is arranged on sealing plate 4
It is exposed to inlay two symmetrical electrode plates 7 on the outside of sealing plate 4, the side wall of installation cavity 3, and electroactive polymer 5 is located at
Between two electrode plates 7, in use, two electrode plates 7 are powered and produce electric field so that effect of the electroactive polymer 5 in electric field
Lower flexible, when electroactive polymer 5 is in most long, electroactive polymer 5 is contacted with sealing plate 4 so that sewing needle 6 is fully extended,
Storage line roller 8 is connected by strut 2 on the side wall of handle 1, the sewing line on storage line roller 8 is through on sewing needle 6.
This can be produced greatly with the electroactive polymer 5 in electroactive polymer surgical stapling device under electric field action
Deformation and elasticity, so the surgical stapling device controls the deformation of electroactive polymer 5 by the change of electric field so that suture 6
Stretch in the end of handle 1, without manually being clamped sewing needle 6 using needle forceps, improve suture precision, alleviate doctor
The work difficulty of business personnel.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of changes, modification, replace
And modification, the scope of the present invention is defined by the appended.
