Abstract
The invention belongs to medical instrument scope, it is used for the device of liver in-degree sequence in a kind of open abdomen or laparoscopic surgery, is particularly suitable for the Minimally Invasive Surgeries such as laparoscope.It is a kind of device dedicated for liver in-degree sequence that there is the rubber material of certain elasticity to be fabricated to, including the buckle of head end and blocking band two parts even and thereafter form.The buckle of head end includes buckle handle and buckling body, and by lifting clamp Button Handle, to open/close, the blocking on buckling body is with holes to block band with tightening.The blocking belt surface at rear portion is smooth and has certain elasticity, the ligamentum hepatoduodenale where porta hepatis can be wrapped and tighten, to block into hepatic blood flow.And band is blocked to utilize different colours and graduation mark, tightness when blocking band wrapping is distinguished, existing blocking deficiency or tension is eased out to prevent crossing and leads to tissue damage.Present invention processing and manufacturing is easy, at low cost, highly practical, has a vast market foreground.
Description
Technical field
It is especially suitable the present invention relates to the device for being used for liver in-degree sequence in a kind of open abdomen or laparoscopic surgery
For Minimally Invasive Surgeries such as laparoscopes.
Background technology
Liver is human body maximum blood reservior official, and blood supply is extremely abundant, normal adult's blood flow per minute up to 1500ml with
On, mainly by two blood supply pipelines：Portal vein and arteria hepatica, this two kinds of blood vessels enter liver from porta hepatis with row.Currently, it makes
The bottleneck of about operation on liver is still intraoperative hemorrhage.Existing Hemostasis is the Pringle of porta hepatis total hepatic vascular exclusion
Method, this method is simple, easy to operate, blocks using finger or tourniquet clamp, is mainly used in open surgery.In recent years,
With application of the minimal invasive techniques such as laparoscope in operation on liver, in-degree sequence becomes the main bottle for restricting field progress
One of neck.Therefore, in-degree sequence when similar open surgery can be currently realized there is an urgent need for a kind of equipment.
Invention content
The technical problem to be solved by the present invention is to overcome the above-mentioned deficiency in the presence of the prior art, and provide a kind of reality
With prominent function, reasonable in design, the device of in-degree sequence can be easily and effectively realized.
Technical solution is used by the present invention solves above-mentioned technical problem：A kind of rubber material system with certain elasticity
The device dedicated for liver in-degree sequence being made, it is characterised in that：Buckle and company including head end and resistance thereafter
Broken belt two parts form.The buckle of head end includes buckle handle and buckling body, by lifting clamp Button Handle to open/close on buckling body
Blocking it is with holes with tightening block band.The blocking belt surface at rear portion is smooth and has certain elasticity, can wrap and tighten porta hepatis
The ligamentum hepatoduodenale at place, to block into hepatic blood flow.And band is blocked to utilize different colours and graduation mark, it distinguishes and blocks band
Tightness when wrapping, to prevent easing out excessively, existing blocking is insufficient or tension leads to tissue damage.
The invention has the advantages that compared with prior art, there is following positive effect：Utility function protrudes, structure
Reasonable design can be blocked effectively into hepatic blood flow, reduce operative hemorrhage, keep surgical field of view clear.It is easy to operate, when shortening operation
Between, improve efficiency.Present invention processing and manufacturing is easy, of low cost, more suits the needs of surgery of liver clinical treatment.
The present invention really belongs to innovation in structure design etc., clinically similar product there is no to use at present, highly practical, tool
There are preferable market prospects.

Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings and by embodiment.
Embodiment：
As shown, the present invention in laparoscopic surgery in use, isolate ligamentum hepatoduodenale first, use surgical clamp
Drawing target seeker 16 will block band 2 around ligamentum hepatoduodenale.Then it is another surgical clamp with fixed handle 5 be rely on, lifting
Movable handle 7 blocks band import 12 to open, from blocking band outlet 14 to involve after 16 are sent by 12, i.e., by ligamentum hepatoduodenale
It surround and finishes.After the pliers for unclamping lifting 7, you can latch 11 is blocked 2 by the elastic force of spring 9, to reach blocking liver
The purpose of blood flow, and 2 can be further tightened as needed to realize best haemostatic effect.During tightening blocks band, pay attention to
Its tightness, guiding area 17 from 14 involve after can realize a degree of bloodstream blocking, appropriate adjust can be needed according to operation
It is whole, but can't should excessively be pulled in the range shown in 18 graduation mark of safety zone, 15 color, especially no more than danger area
19 indicating graduation, in order to avoid cause tissue damage.7 can be lifted after operation unclamps 2 to open 12 and 14.
Above-described embodiment is highly preferred embodiment of the present invention, and it is wanting for in-degree sequence which, which can meet operation,
It asks, and the generation in important blood vessels to prevent massive haemorrhage can be preset at.The embodiment not makees any type of limitation to the present invention,
The technical spirits such as all structure, feature and principles according to the present invention to above-described embodiment made it is any it is simple change, it is equivalent
Variation and modification, belong to the scope of the present invention.
Claims (5)
1. being used for the device of liver in-degree sequence in a kind of open abdomen or laparoscopic surgery, main material is surface light
Rubber product that is sliding and having certain elasticity.
2. in-degree sequence device as described in claim 1, it is characterised in that：Buckle including head end and even with thereafter
