Description
Technical field
Technical field of medical instruments is the utility model is related to, particularly a kind of arteriopuncture sleeve pipe of end of tape sacculus.
Background technology
In recent years, as the improvement of laparoscopic surgical instruments and the progress of surgical technic, laparoscopic partial nephrectomy exist
Gradually successfully carry out both at home and abroad.But operation requires high, not only to cut off lesion, kidney operation is also sutured within the limited time and is cut
Face.If do not blocked the kidney base of a fruit in art, though avoiding the influence of the substantially hot ischemic of kidney, intraoperative blood loss can increase, and exposure is bad, gives
Removal lesion tissue brings difficulty, or even the threat to life because of bleeding with the relevant structure of identification.If the temporary interruption kidney base of a fruit in art,
Amount of bleeding will be reduced, and visual area is clean, can accurately recognize pathological tissues, is advantageous to accurate tumor resection, especially be gathered in suture
During system advantageously, suture more accurate.But due to the influence of hot ischemic, operating time can limit, in art, renal function is not
Can damage with can avoiding, especially for solitary kidney or functional isolation kidney neoplasms patient, Renal Function After can under
Drop results even in renal insufficiency.At present, laparoscopic renal artery hypothermia perfusion operation is carried out under almost without blood state, is used
Blood volume is at utmost reduced；Operation section structure understands, is advantageous to aggregation system and myometrial suture, shortens suture time；
Cool fast and reliable, the renal ischaemia time can be obviously prolonged so that the complicated major operation such as big tumour is implemented as possibility.Uniquely
Shortcoming is to need arteria renalis puncture technique under special blocking device for casting and laparoscope, and this shortcoming seriously limits the operation
Popularize.
Utility model content
The shortcomings that the purpose of this utility model is to overcome prior art, there is provided one kind is used for laparoscopic renal artery low temperature and filled
Note the arteriopuncture sleeve pipe of the end of tape sacculus of operation.
The purpose of this utility model is achieved through the following technical solutions：The arteriopuncture sleeve pipe of end of tape sacculus, including
Outer tube body and the interior tube body being coaxially disposed inside outer tube body, exocoel, interior tube body inside shape are formed between outer tube body and interior tube body
Into inner chamber, described outer tube body includes conical tip, sacculus and the straight sections being fixedly connected sequentially along direction from front to back,
Sacculus is connected Ji Wei exocoel with straight sections.
Further, the both ends sealing of described outer tube body, the front end of interior tube body and the front end flush of outer tube body and is opened
Mouthful, the rear end of interior tube body passes outer tube body, and nook closing member, which runs through, to be arranged in inner tube intracoelomic cavity.
Further, the first connecting portion of connection exocoel is connected with rear side of described outer tube body, described interior tube body
Rear side is connected with the second connecting portion of communication with cavity.
Preferably, there is 10 ° -20 ° of angle between the part of first connecting portion connection outer tube body and outer tube body, the
There is 10 ° -20 ° of angle between the part of two connecting portions connection interior tube body and interior tube body.Make it easy to insert from hysteroscope sleeve pipe
The double lumen tube.Water or gas are injected into the outer tube body of double lumen tube by first connecting portion.Low temperature is filled by second connecting portion
Fluid injection is injected into double lumen tube inner tube.
Further, check valve is provided between first connecting portion and outer tube body, between second connecting portion and interior tube body,
Prevent liquid from flowing backwards.
Further, connecting portion end has screw thread or other attachment means, is easy to connect with vitro perfusion liquid storage device
Connect.
The elastic properties of materials of balloon portion is greater than the elasticity of straight sections material, in unimplanted water or gas, will not projection into
Sacculus shape, in use, under the guided puncture of nook closing member, the device conical tip is punctured into arteria renalis blood vessel so that ball
Capsule portion is located at internal blood vessel, and nook closing member is plugged with described inner chamber, now, exits nook closing member, then a bit, then the device is sent into
Water or gas are injected into the outer tube body of double lumen tube, sacculus is expanded into spheroid, for the blood flow in interruption artery blood vessel, by pin
Core is extracted from two-chamber pipe end, and hypothermia perfusion liquid is injected into double lumen tube inner tube, so as to enter artery by cone point
Blood vessel.
The utility model has advantages below：
The utility model is used for hypothermia perfusion perfusion to kidney in laparoscope or robot arteria renalis hypothermia perfusion operation
In artery.
The double lumen tube is penetrated in artery, after first connecting portion injection water or gas, because end sacculus expands, and blocking blood flow
While, enable the card that double lumen tube consolidates in the artery, do not extruded by arterial pressure, thus need not additionally fix, it is easy to
Operated with the small space of the quiet operation of chamber.
After extracting nook closing member, directly hypothermia perfusion liquid is injected in artery by inner tube by second connecting portion, without again
Put pipe.
First connecting portion, second connecting portion and two-chamber pipe surface are in 10 ° -20 ° of angle so that easily from hysteroscope sleeve pipe
Insert the double lumen tube so that than the perfusion liquid more low temperature of interventional procedure injection, because the conduit of intervention enters from thigh vein,
The very long distance of migration in vivo, and driven in the wrong direction with arterial blood, so when perfusion liquid reaches kidney, temperature has been raised to 15
To 20 degree, good cryogenic effect is not reached, double lumen tube of the present utility model causes perfusion liquid directly to enter from abdominal cavity, do not had
Convection current, temperature is low, and effect is good.
Sophisticated tapered, the cooperation nook closing member of device, easy puncture vessel.
Connecting portion end has screw thread or other attachment means, is easy to be connected with vitro perfusion liquid storage device.
Connecting portion is respectively provided with check valve with double lumen tube junction, prevents liquid from flowing backwards.
