Abstract

The utility model relates to surgical medical equipment technology fields, and in particular to porta hepatis in-degree sequence device under a kind of laparoscope.The device of blocking out blood flow is made of casing and bounding wire.Casing is both ends open, and one end end is horn-like disk, other end end equipped with clamp button of the spring.Clamp button of the spring presses opening, unclamps and close, and clamp button of the spring can be by bounding wire clamping fixed.Since cannula tip is horn-like disk, the power when tightening bounding wire will pass through disk dispersion, enter liver blood vessel risk of rupture so as to avoid hepatic portal.Simultaneously, it is therefore prevented that CO in surgical procedure₂Gas is from casing to outward leakage.It is more flexible and convenient using the fixed bounding wire of clamp button of the spring.

Description

Porta hepatis in-degree sequence device under a kind of laparoscope

Technical field

The utility model relates to surgical medical equipment technology fields, and in particular to porta hepatis enters liver blood under a kind of laparoscope Flow block device.

Background technique

In liver abdominal, liver is since blood supply is abundant, in order to reduce intraoperative hemorrhage, often to hepatic portal position blood vessel Implement to block.Clinical common method is to be tied up using rope or urinary catheter to hepatic portal position or using hilus hepatis blocks pincerses, passed through Hepatic portal position blood vessel is tied up or vised to reach blocking purpose.As the continuous development of medical technology improves, abdominal cavity at present Mirror Minimally Invasive Surgery is widely used in operation on liver, using rope or urinary catheter to hepatic portal position in laparoscope liver Minimally Invasive Surgery Blood vessel is tied up, to reach blocking purpose.

Application No. is: 200920127107.7, the Chinese patent of entitled " Porta blocking-up device " discloses a kind of structure Simply, low in cost, easy to operate, can be used for laparoscopic surgery can be to the Porta blocking-up device that hepatic portal is effectively blocked. The hose end of the Porta blocking-up device, casing merging abdominal cavity is pressed on hepatic portal, and bounding wire tightening, hepatic portal is blocked.Casing is not If hose other end tail portion setting hook, bounding wire is fixed on outside casing by hook, and clogs casing with plug, prevents from performing the operation CO in the process₂Gas is revealed from casing.When casing both ends are equipped with hose, vessel forceps clamp hose segment outside union body and Line equally reaches barrier effect.Although the one end for being placed in abdominal cavity is hose, when tightening bounding wire, since impetus exists Hose end, the power inconvenience dispersion of tightening bounding wire, it is larger to enter liver blood pipe pressure to hepatic portal, and there are hepatic portals to enter liver blood tracheal rupture danger Danger；Casing peripheral hardware hook clogs casing operations and inconvenience with plug；Since bounding wire is located in hose, vessel forceps are not necessarily Bounding wire can be clamped；Vessel forceps must be clipped in hard tube and hose connection, and otherwise hose can be shunk to merging abdominal cavity one end, cause Line relaxation is tied up, vascular inflow occlusion is not achieved and enters hepatic blood flow purpose.

Summary of the invention

The purpose of this utility model is intended to overcome the shortcomings of in background technique, provides that a kind of structure is simple, operation is more pacified Entirely, porta hepatis in-degree sequence device under easy and practical laparoscope.

To achieve the above object, the utility model uses following technological means: porta hepatis enters liver blood under a kind of laparoscope Block device is flowed, is made of casing and bounding wire.

Casing both ends open, casing one end end are horn-like disk, other end end equipped with clamp button of the spring.

Bounding wire covers on ligamentum hepatoduodenale.

Clamp button of the spring presses opening, and clamp button of the spring, which unclamps, closes.Clamp button of the spring can be by bounding wire clamping fixed.

The utility model beneficial effect: since cannula tip is horn-like disk, the power when tightening bounding wire is just led to Disk dispersion is crossed, enters liver blood vessel risk of rupture so as to avoid hepatic portal.Simultaneously, it is therefore prevented that CO in surgical procedure₂Gas is from casing To outward leakage.It is more flexible and convenient using the fixed bounding wire of clamp button of the spring.

Detailed description of the invention

Fig. 1 is overall structure cross-sectional view.

Figure number explanation: 1-casing；2-bounding wires；3-disks；4-clamp button of the spring.

Specific embodiment

Technical solution is further illustrated as embodiment below in conjunction with attached drawing.Porta hepatis enters liver under a kind of laparoscope Device of blocking out blood flow is made of casing 1 and bounding wire 2.

1 both ends open of casing, 1 one end end of casing are horn-like disk 3, other end end equipped with clamp button of the spring 4.Casing 1 is duroplasts, and 1 length of casing is greater than stamp card length used in surgical procedure.The disk 3 is flexible plastic, 3 horn mouth of disk Outer diameter is less than stamp card internal diameter used in surgical procedure.

2 sets of bounding wire on ligamentum hepatoduodenale, bounding wire 2 be medical cotton thread.

Clamp button of the spring 4 presses opening, and clamp button of the spring 4, which unclamps, closes.Clamp button of the spring 4 can be by 2 clamping fixed of bounding wire.

Porta hepatis in-degree sequence device under a kind of laparoscope can be made into according to above-mentioned technical proposal, and when use will set Pipe 1 is put into intraperitoneal from stamp card, and disk 3 is preceding, and casing 1 is equipped with 4 end of clamp button of the spring, and to be located at stamp card outer.Pressing clamp button of the spring 4 will The bounding wire 2 covered on ligamentum hepatoduodenale pulls out outside casing 1 from disk 3.After the tightening of bounding wire 2, trip spring buckle 4, bounding wire 2 is clamping fixed, to achieve the purpose that block into hepatic blood flow.
