Abstract
The utility model is related to medical instruments field, and in particular to a kind of laparoscope hepatic portal blocking belt.It includes silicone tube, elastic webbing, annulus, and the connection of silicone tube front end is equipped with an elastic webbing, and elastic webbing front end is equipped with inside annulus, silicone tube is equipped with flap valve close to upper end position.Advantage is that design is simple, and easy to use, occupancy operative space is few, can effectively realize bloodstream blocking.
Description
Technical field
The utility model is related to medical instruments field, and in particular to a kind of laparoscope hepatic portal blocking belt.
Background technology
There is domestic literature（Zhu is newborn, and Zhang Yuemin, Li Baihong wait parts hepatic vascular exclusion device to be cut in laparoscope liver
Except the application Third Military Medical Universitys journal in art, 2009,29 (14)：1447-1448；Lu Bangyu, Lu Wenqi, Cai little Yong, wait
The Chinese scope magazines of application of the portal blood blocker in partial hepatectomy, 2005,11 under hysteroscope：982-983.）Report
In road, laparoscopic liver resection, various simple hepatic portals are voluntarily developed in a small number of medical centers on the basis of using existing apparatus
Block device, but not widely approved and promote, reason is not allow under laparoscope easy to operate, and part blocks are not thorough,
Follow-up operation may be influenceed.
Abroad, there is the special vascular occlusion clamp of laparoscope, it can be used for blocking porta hepatis.Domestic minority medical center
There is introduction, it is also possible to the follow-up operation of influence.
Above-mentioned various apparatuses using a kind of reality strapping or block pincers to go to tie up, clamp ligamentum hepatoduodenale
So as to realizing bloodstream blocking, but to realize tie up, clamp is not allowed easy to operate under laparoscope, part blocks are not thorough, therefore block
Less effective；An operation path and certain intraperitoneal space need to be taken in addition, may influence follow-up operation.
The content of the invention
In order to solve the problems, such as foregoing invention, the utility model proposes a kind of laparoscope hepatic portal blocking belt, design is simple, makes
It is few with operative space conveniently, is taken, it can effectively realize bloodstream blocking.
In order to reach foregoing invention purpose, the utility model proposes following technical scheme：
Hysteroscope hepatic portal blocking belt, it includes silicone tube, elastic webbing, annulus, and the connection of silicone tube front end is equipped with an elastic webbing,
Elastic webbing front end is equipped with inside annulus, silicone tube is equipped with flap valve close to upper end position.
Described silica gel pipe range 15-20cm.
Described elastic webbing is solid elastomeric band, and its length is 25-30cm.
Described flap valve includes two diaphragms, and two diaphragms are arranged on inside silicone tube in 60-90 degree angle.
The utility model has the advantages that design is simple, easy to use, occupancy operative space is few, can effectively realize blood flow
Block.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Referring to the drawings, hysteroscope hepatic portal blocking belt, it includes silicone tube 1, elastic webbing 2, annulus 3, the front end of silicone tube 1 connection dress
There is an elastic webbing 2, the front end of elastic webbing 2 is equipped with annulus 3, and the inside of silicone tube 1 is equipped with flap valve 4 close to upper end position.
The described long 15-20cm of silicone tube 1.
Described elastic webbing 2 is solid elastomeric band, and its length is 25-30cm.
Described flap valve 4 includes two diaphragms, and two diaphragms are arranged on inside silicone tube in 60-90 degree angle.
During Laparoscopic operation, typically several assisted surgery holes can be held in patient body relevant position again, for operating theater instruments
It can enter and implement operation in patient body, it is of the present utility model in use, the Trocar sleeve pipes of operation are entered by surgical hole
In patient body, the Trocar sleeve pipes for the annulus, elastic webbing and silicone tube of the present apparatus then being passed sequentially through operation are transported to disease
In human body, then surgical staff enters operating forceps in patient body, under the observation of laparoscope by another Trocar sleeve pipe
Annulus traction elastic webbing is pinched by operating forceps and bypasses the blood vessel to be blocked, then annulus and elastic webbing are passed through silicone tube to patient
In vitro, elastic webbing is outwards pullled, while silicone tube will extrude blood vessel with elastic webbing, blood vessel blocking, at this moment outside is elasticity
Band logical is crossed operation clamp and fastened, and prevents blood vessel blocking from loosening, after operation terminates, the release present apparatus, contrary operation above-mentioned steps,
Blood vessel insertion again can just be made, flap valve plays unidirectional valve action in silicone tube, prevent the gas overflowing being injected in vivo during operation,
When elastic webbing passes through flap valve, flap valve can still be sealed, it is ensured that internal gas will not overflow.
