Description
Technical field
The utility model is related to a kind of instrument for being used to set up the laparoscopic surgery visual field, particularly discloses a kind of non-pneumoperitoneum hand
Device is set up in the art visual field.
Background technology
With continuing to develop for Minimally Invasive Surgery, laparoscopic surgery with its wound it is small, recover fast the advantages of increasing quilt
Applied to clinic.In laparoscopic surgery, how to create good surgical field of view and operative space is asking firstly the need of solution
Topic.
CO is most commonly used that into the abdominal space creation method of intraperitoneal inflation2 Pneumoperitoneum, it is that current surgical field of view is built
Found abdominal space that is best, being most widely used and set up mode；But which easily causes subcutaneous and mediastinal emphysema, high carbon acid
The complication such as mass formed by blood stasis and acid poisoning, shoulder are ached, arrhythmia, deep veins of lower limb extravasated blood and thrombosis, abdominal viscera ischemic,
Even Iisolated tumor cells can be made to be sent out intraperitoneal.And change vector gas（Such as N2O, helium etc.）Sub-fraction can only be reduced
Complication, and be not suitable for because cardio-pulmonary function difference can not be resistant to the patient of pneumoperitoneum operation.
In order to break through the limitation of artificial pneumoperitoneum operation, prevent the brought complication of artificial pneumoperitoneum operation, non-pneumoperitoneum hand
Art gradually grows up.Non- pneumoperitoneum sets up the machine that abdominal space method is the patient's acquisition minimally-invasive treatment for not being resistant to pneumoperitoneum operation
Meeting, it is to avoid the complication caused by gas filling, can effectively mitigate the postoperative shoulder pain of patient, be conducive to patient postoperative extensive
It is multiple；The smoking problem in gas laparoscopy operation is solved, surgical field of view is maintained clearly.However, existing non-pneumoperitoneum
All there is the not enough defect of operative space exposure in abdominal space creation method, main cause is that this method can make when lifting stomach wall
Bilateral stomach wall is assembled to centre, and extruding intestinal tube is concentrated to centre, causes operative space to diminish, narrow, Muscle tensility is larger.
In order to break through the limitation of artificial pneumoperitoneum operation, prevent the brought sequelae of artificial pneumoperitoneum operation, non-pneumoperitoneum hand
Art gradually grows up.Can apply generally has following several ways in clinical：
1st, by the way of suspention is without pneumoperitoneum operation：Mainly patient's stomach wall is led upwards by external pipe-hanging hook
Draw, make intraperitoneal generation operative space, this way is simple and easy to apply, but be due to that pipe-hanging hook is pulled to stomach wall in vitro
When, intraperitoneal internal organs can follow the drawing of stomach wall to produce displacement, so as to cause surgical field of view is narrow, appear uneven etc. to ask
Topic；In upper abdomen, because important organ is more, therefore operation relative difficulty.Meanwhile, once excessively lifting stomach wall is likely to result in group
Separation is knitted, abdominal subcutaneous wind-puff is formed, is unfavorable for post-operative recovery.
2nd, by the way of built-in expanding mechanism：Utility model patent such as Application No. 200820112893.9 is disclosed
A kind of support tent-type non-pneumoperitoneum device, it is mainly by connection 2 elastic wire support bars between the substrates to stomach wall
It is supported, substrate, which is located at that patient is external, during support, support bar main body is domed is located at intraperitoneal, and support front support rod needs to exist
Patient is punctured to abdominal cavity in vitro, is fitted during puncture with internal organs due to stomach wall, abdominal cavity camber, can increase venipuncture difficulty, very
To damage is caused, device is dirty, puncture failure consequence；And this expansion pattern actually not fully belongs to built-in expansion, it is supported
Support of the bar to stomach wall still results in internal organs and gathered to centre, and influences surgical field of view, meanwhile, the puncture meeting of two support bars
At least four point of puncture is caused on stomach wall, not only artificial increase wound, and under the supporting role of support bar, point of puncture week
Lasting traction action can be produced by the influence of reaction force by enclosing stomach wall, cause the phenomenons such as point of puncture wound expansion.And abdominal cavity
Mirror then needs to carry out otch on stomach wall in addition, so excessive to the wound of stomach wall, is unfavorable for patient's post-operative recovery.
The content of the invention
The purpose of this utility model is to overcome defect present in prior art there is provided one kind, simple in construction, user
