Abstract
The utility model discloses a pancreas negative pressure pjncture needle, including urceolus, inner tube, outer needle core and interior nook closing member and set up and fixedly between urceolus and inner tube establish rubber sleeve, interior barrel casing is established in the urceolus, the fixed outer needle core that is equipped with of one end of inner tube, interior nook closing member cover establish the outer needle in -core and with inner tube fixed connection, the inner tube passes through the tip fixed connection of spring and urceolus in the one end of outer needle core. The utility model has the advantages of simple structure, low in cost, and the practicality is strong, can be used for puncturing through the outer needle core and organize, and interior nook closing member can be used for the cell that punctures to be favorable to drawing of tissue and cell, can effectually slow down pressure through spring and rubber sleeve, prevent that the doctor is too big hard, cause huge pain, convenient to use to the patient, the utility model discloses can effectual improvement the excision rate of tumour in the operation, to the surgeon be fine surgical instruments, simultaneously can shorten operation time, reduce postoperative recurrence and metastasis 's influence as far as possible.
Description
Technical field
This utility model relates to a kind of puncture needle, particularly to a kind of pancreas negative-pressure puncture needle.
Background technology
After pancreas is positioned at peritoneum, anatomical position exists deeply, visual field difficult exposure, and it is close to the important blood vessels such as portal vein, superior mesenteric vein, the splenic vein, coeliac trunk and superior mesenteric artery, the touch to tumor and extruding it is very difficult to avoid completely when radical surgery, blood plus pancreas supplies and lymph circulation is extremely abundant again, will certainly increasing in operation tumor cell to the risk in blood vessel, lymphatic channel even abdominal cavity and Peritoneal metastasis, this is likely to also be recurrence and the high major reason of the rate of transform after radical Resection for Adenocarcinoma of Pancreas.
The difficult point of another main cancer of pancreas operation technique is that prevention and the process of pancreas fistula.No matter pancreatic juice, due to stronger corrosivity, is that pancreas stump closes spacious putting with intestinal anastomosis or stump, all there is pancreas fistula.For the Pancreas cancer patients that cannot excise, art takes pathology and often there will be the possibility of damage pancreas main pancreatic duct, pancreas fistula occurs, hemorrhage, it is also possible to have the chance of tumour spread.
Existing pancreatic surgery apparatus also exists deficiency, replaces, for operating fine blood vessel separation and vessel resection, the apparatus that can use vascular surgery, but just relatively not good enough for separation, there is no the effect well protecting blood vessel.Wherein, but can run into during pancreatic surgery and have lump pancreas whole process quality consistent or caput pancreatis afterbody all has lump, it is necessary to during row full pancreas excision, the inspection of histopathology to be obtained.The shortage of pancreas puncture needle in art, causes that cell and biopsy cannot be smoothed out, because puncture needle all has greatly disadvantage for injury of pancreas and pancreas fistula, also easily caused by the hematoma of point of puncture.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, it is provided that a kind of pancreas negative-pressure puncture needle, not only can extract cell, and can extract tissue, it is simple to use.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
This utility model one pancreas negative-pressure puncture needle, including urceolus, inner core, outer nook closing member and interior nook closing member and be arranged between described urceolus and described inner core and be fixed with rubber sleeve, described inner core is set in described urceolus, one end of described inner core is fixed with described outer nook closing member, described interior nook closing member is set in described outer nook closing member and fixes with described inner core and is connected, and described inner core is connected by spring is fixing with the end of described urceolus in one end of described outer nook closing member.
As a kind of optimal technical scheme of the present utility model, the end of described urceolus is fixed with sucker.
As a kind of optimal technical scheme of the present utility model, described urceolus is fixed with the handle of correspondence on the outer wall of tail end.
As a kind of optimal technical scheme of the present utility model, the other end of described inner core is fixed with handle.
As a kind of optimal technical scheme of the present utility model, the head of described outer nook closing member and described interior nook closing member is angle cutting-edge structure.
This utility model reaches to provide the benefit that: simple in construction of the present utility model, cheap and practical, by being provided with outer nook closing member and interior nook closing member, outer nook closing member may be used for puncturing tissue, and interior nook closing member may be used for puncturing cell, thus being conducive to the extraction of tissue and cell；By being provided with spring and rubber sleeve, it is possible to effectively slow down pressure, it is prevented that doctor is firmly excessive, and patient is caused great pain, it is simple to use；This utility model can effectively improve the resection rate of tumor in operation；It is good operating theater instruments for surgeon, operating time can be shortened simultaneously, reduce the impact of postoperative recurrence transfer as far as possible.
