Description
Technical field
The utility model relates generally to the suture instruments more particularly to a kind of endoscope-assistant surgery suture dress of Minimally Invasive Surgery application
It sets.
Background technique
Micro-wound surgical operation damages the superperformance that small, bleeding is few, post-operative recovery is fast because of it, receives clinical doctor in recent years
The common attention of teacher and patient, are used widely in clinic.Intraperitoneal biologic soft tissue area is big, structure is changeable, and surface is wet
It slides and there is flexibility.Endoscope-assistant surgery suture is a kind of technological challenge for endoscope-assistant surgery doctor.It is usually required using limited
Step carries out suture knotting to tissue.Endoscope-assistant surgery suture challenge is mainly in the following: 1, patient is under a three-dimensional space
It is operated, but vision can only see the operation under two-dimensional space.2, it is operated since patient using elongated rigid axial rod,
Most challenge be by organize for crawl sewing needle and positioning lack wrist activity；What is more, after it has been gathered
How suitable knot, safety that how by tiny hysteroscope channel in tissue suitable position guarantee to tie are played.
Existing endoscope-assistant surgery suture instruments carry out manual suture or using stapler to tissue generally by looper
Stapling is carried out, there is the problems such as suture inefficiency, operation is time-consuming and laborious.If can be under the premise of guaranteeing tissue seam area
It only can continuously be sutured by singlehanded realization, will greatly simplify doctor's operating process, raising sutures efficiency, it is extensive to be conducive to patient
It is multiple, while promoting suture quality and accuracy.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of compact-sized, operation
Energy and comfort, endoscope-assistant surgery stitching devices highly-safe, that suture time can be shortened.
In order to solve the above technical problems, the utility model uses following technical scheme:
A kind of endoscope-assistant surgery stitching devices, including driving handle, connection loop bar and two arc stylophores, the driving handle
It is connected to one end of connection loop bar, two arc stylophores are in the another end for being symmetrically connected to connection loop bar, are lived in any arc stylophore
Dynamic to be set with suture looper, two arc stylophores, which are further sleeved with to extend in connection loop bar, back and forth send needle device, and two are back and forth sent
It is equipped with the secondary push rod being located in connection loop bar between needle device, is equipped with and is located in connection loop bar between the driving handle and secondary push rod
Primary push rod, when blocked operation driving handle, primary push rod drives secondary push rod alternately back and forth to send needle device to be formed with two respectively to connect
It connects, two are back and forth sent the alternate pushing tow suture looper of needle device that it is driven to move back and forth between two arc stylophores.
As a further improvement of the above technical scheme:
The primary push rod is disposed with multiple voussoirs and pushing block along the circumferentially-spaced of pushing end, and the pair push rod is along by pushing away end
It is circumferentially-spaced to be disposed with multiple rotations to match respectively with voussoir and pushing block by pushing block and straight trip by pushing block, work as driving handle
When driving the rotation of voussoir pushing tow by pushing block, the pair push rod back and forth send needle device to connect with needle to be sent, pushes away when driving handle drives
When the straight trip of block pushing tow is by pushing block, the pair push rod drives the reciprocal of needle to be sent that the straight trip of needle device is sent to send needle.
It is described back and forth to send needle device including sending shank and reset spring, it is described that shank one end is sent to extend in corresponding arc stylophore,
The other end replaces connection with secondary push rod, and the reset spring, which is sleeved on, to be sent on shank.
Described to send shank to open up in connecting pin fluted, and the pair push rod is equipped with convex block, the rotation of voussoir pushing tow in pushing end
When by pushing block, the convex block rotation is simultaneously coupled with corresponding groove, and when the straight trip of pushing block pushing tow is by pushing block, convex block pushing tow groove is driven
Secondary push rod straight trip.
It is described that shank is sent to be set as rubber card division in the part protruded into arc stylophore.
The end face for sending shank to engage with rubber card division is set as magnetic face.
The driving handle includes fixed handle and press handle, and the fixed handle is packed in connector sleeve boom end, the pressing
Handle is movably hinged with fixed handle and connect with primary push rod.
Reduction torsion spring is installed between the fixed handle and press handle.
Compared with the prior art, the advantages of the utility model are:
The endoscope-assistant surgery stitching devices of the utility model, when operation, one hand pressing driving handle is primary, driving handle pushing tow
Primary push rod, what primary push rod drove secondary push rod and needle to be sent back and forth send needle device to connect, then when pressing one time, primary push rod drives secondary push rod
This back and forth send needle device to straight trip pushing tow, so that needle device is back and forth sent to send out the arc stylophore for looper is sutured, while suturing looper and passing through
It performs the operation and position to be stapled and enters another arc stylophore, when pressed once, primary push rod drives secondary push rod again with other one
A needle to be sent back and forth send needle device to connect, and then presses primary push rod again and drives secondary push rod straight trip pushing tow this back and forth send needle device, and will
Suture looper sends out the arc stylophore and returns to former arc stylophore, acts, acts according to this past as primary complete suture
Multiple operation is until complete suture operation.For more traditional manual suture or use stapler, which is used certainly
Automatically thread a needle suture of the reciprocal connected structure realization to tissue is moved, has angle controllable, one-hand operation, so that it is another to liberate patient
On the other hand, Various Tissues organ is adapted to, operation is more precisely safe.The stitching devices of the utility model are compact-sized, and patient is avoided to stitch
Fatigue caused by wrist inconvenience is turned round when needle, it is simple to operate, patient's operating comfort and convenience are improved, is shortened effectively
Suture time, and then help to shorten patients surgery time raising medical safety.
