Blocking and release hepatic portal be the key that guarantee operation safety carry out.
Present operating method is that one No. 8 red urinary catheters are passed through porta hepatis rear through laparoscope, and Pringle method surrounds liver
After duodenum ligament knots, Hemlock folder is pressed from both sides with vascular inflow occlusion in node.Existing scheme is because complicated for operation, consumption
When it is longer, need assistant's cooperation skilled, if knot do not have it is urgent exist block not exclusively may, cause big bleeding in art.In addition, releasing
Hemlock need to be cut when putting hepatic portal and presss from both sides and take out disconnected folder, increase the complexity and operation duration of operation.If can be as opening abdomen
Hepatic portal is quickly and effectively blocked and discharged when operation, and the liver that laparoscopic dissection hepatotomy is equivalent under open state cuts
It removes, the safety of operation and controllability are just greatlyd improve.
Summary of the invention
Shortcoming according to prior art is fixed conveniently and can prevent abdomen the invention proposes a kind of easy to operate
Vascular blocking device when the Control of Hemorrhage in Laparoscopic Liver excision of carbon dioxide gas leakage.
In order to solve the above technical problems, the invention adopts the following technical scheme: laparoscopic dissection liver cuts blood vessel blocking
Device, including being arranged along the vertical direction and the casing of inner hollow, cannula tip is fixed with soft pressing plate, sleeve bottom sliding
It is arranged with soft cover board, casing shoe is securing elongated hose, and cannula center is provided with rope pulling device, rope pulling device under original state
Soft pressing plate is stretched out in one end, and the other end of rope pulling device stretches out hose, and the middle part of hose is equipped with clip, and the top of casing is equipped with storage
Device, soft pressing plate is accommodated in inside collector under original state.
Rope pulling device includes pull rod, and the top of pull rod is fixed with tether ring, and the bottom end of pull rod is fixed with handle, tether ring
For flexible material, the center of soft pressing plate is equipped with through-hole, and under working condition, tether ring passes downwardly through the through-hole of soft pressing plate and position
In inside pipe casing.
Collector includes containing tube and push rod, and containing tube is set in cannula tip, and the internal diameter at the top of containing tube is greater than casing
Outer diameter, along inner surface, the heart is provided with fin thereto for the bottom of containing tube, and the top of casing offers top along its length
Open guide chute, fin are slidably connected in guide chute, are fixedly connected with push rod below containing tube.
The outer diameter of casing is 3~8mm, and the length of casing is 20~30cm.
Bushing outer surface is provided with scale.
Fin and guide chute are arranged in pairs, and fin and guide chute are set as a pair of or several right.
By adopting the above technical scheme, the invention has the following beneficial effects: utilization rope pulling device drawings to block band, and matches co-clip
Son is fixed, easy to operate.
It is provided with soft pressing plate, blood vessel is pressed while blocking blood vessel, increase barrier effect and injury of blood vessel can be prevented.
It is provided with collector, soft pressing plate is stored under external state, is facilitated in occluding device insertion body, and wound can be reduced
Face.
It is provided with soft cover board, cooperation clip folder closes hose, can effectively prevent the leakage of abdomen carbon dioxide gas.
Bushing outer surface is provided with graduation apparatus, facilitates control block device to be inserted into intracorporal depth, standardizes to operation.
In summary: the present invention can block the blood vessel for implementing operation, and effect is equal to out under abdomen state
Blocking way can be blocked and be discharged at any time, and it is convenient to fix in vitro, and can prevent abdomen carbon dioxide gas from revealing, convenient for specification
Operation, substantially increases the safety and operability of operation.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
Embodiment: laparoscopic dissection liver as shown in Figure 1 cuts vascular blocking device, including be arranged along the vertical direction and
The casing 1 of inner hollow, 1 top of casing are fixed with soft pressing plate 2, and 1 basal sliding of casing is arranged with soft cover board 3, casing 1
Bottom end is securing elongated hose 4, and casing 1 is provided centrally with rope pulling device, and soft pressing plate is stretched out in one end of rope pulling device under original state
2, the other end of rope pulling device stretches out hose 4, and the middle part of hose 4 is equipped with clip 5, and the top of casing 1 is equipped with collector, original state
Under soft pressing plate 2 be accommodated in inside collector.
Rope pulling device includes pull rod 6, and the top of pull rod 6 is fixed with tether ring 7, and the bottom end of pull rod 6 is fixed with handle 8,
Tether ring 7 is flexible material, and the center of soft pressing plate 2 is equipped with through-hole, and under working condition, tether ring 7 passes downwardly through soft pressing plate 2
Through-hole and be located at casing 1 inside.
Collector includes containing tube 9 and push rod 10, and containing tube 9 is set in 1 top of casing, and the internal diameter at 9 top of containing tube is big
