Description
Technical field
The present invention relates to field of medical appliances, and in particular to a kind of microsurgery sewing system.
Background technology
Micro anastomosis is often 8-0 to 11-0 models with suture specification in microsurgery operation, needle it is a diameter of
0.05mm to 0.14mm, chord length are 3 to 5mm, and arc length is 3.8mm to 6.4mm, and suture diameter is 0.015 to 0.045mm, length
For 10-15cm.So tiny micro suture needlework, it is high-visible under field of microscope, it must be anti-in comparison under the naked eyes visual field
It is just distinguishable under the larger solid background of difference.Under microscope magnifying state, conventional operating distance be 20-25cm, herein away from
It is difficult to look for due to easily being covered by complicated surgical wound surface background from the microsurgery needlework to fall into operation visual area.
For medical worker when micro- amplification system progress micro suture is performed the operation in application, micro- amplification factor is usually on 10 times of left sides
The right side also needs to be amplified to 40 times sometimes, and the field number for amplifying visual area is usually 9.5mm-20mm（0.95-2cm）.Due to micro-
The length of suture is usually 10-15cm, is far longer than field number, in practical operation, inevitably micro- seam
Close the situation that needle leaves microscopic field.Simultaneously as it by medical worker's skilled operation degree, art area hoc scenario to be stapled, shows
The influence of the factors such as microoperation instrument quality and support staff's skilled operation degree, microsurgery carry out in be difficult to avoid that meeting
There is the phenomenon that " flying needle ", " bouncing pilotage " and " broken needle ".In this case, micro- suture needle, which can be unpredictably detached from, micro- holds needle
Device, usual micro- suture needle can leave field of microscope, and not patient is pre-designed the orientation for placing suture needle.
In some cases, it has knotted fixed microsutures for suture tail portion, medical worker can pass through drawing
Suture quickly finds suture needle.But due to the sharp keen needle of weak part, in addition micro- suture needle that the connecting portion of micro- needlework is stress
Head is easily pierced into neighbouring tissue and causes resistance, and the diameter of microsutures is tiny, improperly firmly is easily allowed to be broken, leads to needle
Line detaches, and the microsurgery surface of a wound is complicated, and nervus vasculairs are densely distributed, and this measure is it is possible that the tissue damage of bigger can be caused.
Therefore, deviate from the micro- visual area of micro- suture needle disengaging, especially suture tail portion with needle, the situation of " broken needle "；
The situation in micro- visual area is remained secured to suture needle abjection but tail portion, in order to avoid external force drawing suture causes needlework to detach or seam
Thread breakage, it is mobile restricted because microscopic field of view diameter is excessively narrow, it is impossible to be used in find micro- suture needle, need patient's naked eyes in complexity
Surgical wound surface background under find micro- needlework.And requirement and working distance of microscope of the aseptic condition to sighting distance performed the operation will
It asks and is more the increase in the difficulty that naked eyes seek needle.In surgical procedure, in order to find the micro- suture needle of " missing ", when can waste a large amount of
Between, being delayed blood vessel and dialyneury process leads to tissue ischemia time lengthening, causes the failure entirely performed the operation；Extend patient's anesthesia
Time can cause the raising of incidence of complications to even result in patient and life danger occurs.
In addition, if micro- suture needle is not found, since it is very tiny, it is difficult to be sent out by conventional B ultrasound, x-ray and CT examination
It is existing.Since micro- suture needle is metal object, it can cause patient that cannot carry out magnetic resonance examination and high-intensity magnetic field ring cannot be entered
Border.Micro- suture needle remains in patient body, can cause very big hidden danger to the health of patient.Suture needle is residual as non-implantable foreign matter
It stays in and easily causes tissue infection in local organization, influence patient's post-operative recovery；If suture is needled into nerve or tendon, then can draw
It plays patient's post-surgical sites pain, lead to the feeling for being difficult to alleviate and dyskinesia；If suture needle is pierced into thin vessels, postoperative blood can be caused
Obstacle is transported, local thrombus formation is caused to lead to local organization ischemic or extravasated blood or even necrosis；If suture needle is pierced into big or middle arteriovenous,
Sewing needle is easily poured big internal blood vessel by rapid blood flow, and sharp syringe needle can damage big blood vessel, cause artery dissection,
The formation of the fatal diseases such as aneurysm；Suture needle reaches whole body vessel branch everywhere with the circulatory system, can lead to heart valve, big
The damage of vein valve etc., causes lateral thrombus to be formed, and thrombus breaks loose can cause whole body important organ embolism threat to life.
Meanwhile for microsurgery beginner, when practicing micromanipulation due to holding needle, inserting needle, the gimmick for going out needle
It is unskilled, it holds needle and overexerts, holds the reasons such as pin position mistake, needle angle, inserting needle positional fault, cause " flying needle ", " jump
The probability of needle " and " broken needle " greatly increases, and beginner usually requires to waste a large amount of time and looks for needle or select new needle, causes not having
Necessary time and the wasting of resources.
There are multiple and different producer's production microsurgery swaged needles both at home and abroad at present, wherein domestic microsurgery suture
Needle it is cheap, although compared with foreign vendor still have a certain distance, material, finish, hardness and sharp keen degree
The requirement of microsurgery can be met.However, being foreign countries or domestic microinstrument and microsurgical instrument manufacturer, all neglect
It is tiny depending on micro- needlework, quick naked eyes is needed to find this actual conditions of suture needle and want in disengaging microscope visual area
It asks.Meanwhile in the relevant corollary equipment of micromanipulation and instrument, in the deisgn product of domestic and international microinstrument producer, do not have
Have and optimized for the situation that naked eyes is needed to find micro- suture needle, also lack the solution to the above situation.
