A kind of endoscopic surgery robot arm device
Technical field
The present invention relates to medical instrument auxiliary device technical fields, and in particular to be a kind of endoscopic surgery mechanical arm dress
It puts.
Background technology
It is applied to clinical medical operating robot system at present and is mostly based on endoscopic surgery principle, is divided into non-invasive procedures
System and minimally invasive surgery system.Noninvasive surgery system by taking the X2Robotic System in the U.S. as an example, operation tool need to lead to
The human body natural's cavity for crossing long and narrow complexity enters patient's body, and operation difficulty is big.Thus single incision operation is in laparoscope hand
Art, thoracoscopic operation field are gradually approved by more people.
The many research institutions of our times are devoted to research single hole endoscope surgery system and achieve certain progress, such as
M.Piccigallo et al. proposes SPRINT systems, which realizes the torsional bending in joint by the micromachine in mechanical arm
Doctor's arm motion is imitated in movement, realizes the single hole endoscope surgery system of a six degree of freedom.Domestic number of patent application is
201410206379.1 single-port laparoscopic minimally-invasive surgery robot system drives the mechanical brachiocylloosis of line driving by Nitinol
It is flexible to wait movement, complete the multivariant motor performance in space.And Yi Shang endoscopic surgery robot arm device is complicated for operation, vision
Feedback unit and the coordination control of surgical procedure unit are difficult, and can be interfered with each other in limited working space.To solve body hand
The problems such as art space is small, visual area exposure difference, is reduced operating difficulty, is generally worked for laparoscopic surgery using artificial pneumoperitoneum
The expansion in space.Artificial pneumoperitoneum is generally built by being filled with carbon dioxide gas to abdominal cavity, and CO2 pneumoperitonium makes gas
Road pressure increases, and it is dissolved in blood circulation system can lead to hypercapnia.
There are some for solution problem above laparoscopic surgery field and exempt from pneumoperitoneum device.Domestic number of patent application is
201220523802.7 laparoscopic surgery exempts from pneumoperitoneum eyelid retractor, and a plurality of steel bar is penetrated abdominal cavity by body surface notch, adjusts steel
Camber forms support domes, to construct larger surgical procedure space.But it, which penetrates process, needs laparoscope to guide,
It is complicated for operation.If the process of penetrating is dealt with improperly, secondary damage may be caused.It, need to be and in addition to the operative incision of endoscopic surgery
Body both sides increase by two complementary procedure notch being used for through steel bar.Considering for security problems is excluded, it is such to exempt from pneumoperitoneum dress
It puts and is applicable only in laparoscopic surgery, it cannot be general for similary narrow thoracoscopic operation operating environment.Therefore it is badly in need of one
Kind novel endoscopic surgery robot arm device solve the problems, such as presently, there are.
Invention content
The purpose of the present invention is to provide a kind of endoscopic surgery robot arm devices, and not only action is simple, easy to use, keeps away
Exempt from mutual interference, can also safely and effectively expand internal surgical workspace, patient will not be made hypercarbia occur
Disease will not cause secondary damage to patient.

One blow vent in internal piston realizes and connects that push rod front end is laid with three strut connecting seats, and putting back-end is consolidated with piston
Entirety is linked as, push rod is installed in the circular hole at partition board center, and rod packing is equipped between circular-hole internal-wall.
Further, the surgical procedure mobile phone structure is mounted on outer tube front end, and support frame is by upper control arm, preceding parallel
Bar, rear parallel bar composition, three support frames are uniformly mounted on outer tube, each support frame four side parallel with outer tube composition
Shape structure, strut form revolute pair and connect with strut connecting seat, preceding parallel bar respectively, preceding parallel bar respectively with outer tube, upper flat
Row bar forms revolute pair connection, and rear parallel bar forms revolute pair and connect with outer tube, upper control arm respectively.
Further, a camera has been respectively mounted on three support frame tops, front end position is leaned on outer tube
Install the camera accommodating groove of corresponding camera.
Further, the outer tube back-end is equipped with air pipe interface, and air pipe interface one end is connected with helix tube rear end, another
End is connected with the air compressor set by outside, and helix tube is installed in air storage chamber, and the blow vent of its front end and piston rear end
Connection, rear end are connected with air pipe interface.
