Description
Technical field
The present invention relates to the hemostasis device near a kind of human body alimentary canal especially stomach bottom.
Background technology
The world is annual because of the people of cirrhosis died about 1,200,000, and cumulative year after year, and most of reason is esophagus caused by cirrhosis
Therapy for Gastric Variceal Bleeding, it is medicine, apparatus, intervention operation and abdominal etc. to commonly use Hemostasis.It is heavy for acute
The acute stages treated of disease bleeding, first-selected conventional means international at present is still Sengstaken-Blakemore tube, also known as Sengstaken-
Blakemore tubes or Minnesota tubes hemostasiss by compression, a small number of doctors use Linton-Nachlas tube (only
One stomach air bag of about 500ml, without esophagus air bag) hemostasis by compression.For a long time, although above-mentioned hemostat device is clinical most of
Act as also being found that many problems during key player, but use in bleeding in esophageal and gastric varices, it is such as common
Secondary avulsion bleeding when complication includes the necrosis of esophageal-gastric bottom mucous membrane, mucosa ulcer, takes out, rare complications following breaks including esophagus
Split, suffocate air flue etc., other unfavorable aspects also include putting pipe difficulty, oppress invalid, compressing adjustment difficulty, balloon rupture, harm
Hinder gastroscope further to check etc..
In addition, as shown in figure 1, the stomach bottom 60 of human body alimentary canal and the end of oesophagus 50 close to.It is existing when the bleeding nearby of stomach bottom
Although having capsule pipe or other hemostat devices to enter at this carries out hemostasis by compression, its local pressure is generally unadjustable.Cause
This, such hemostat device or device are just needed badly during stomach end blood, and it can to stomach bottom bleeding part pressure applied
It is adjusted accordingly according to actual needs with hemostasis.
The content of the invention
It is an object of the present invention to provide a kind of alimentary canal hemostasis device, it can be used in such as esophageal-gastric end blood, and overcome
Above-mentioned certain or some defects for referring to.

Each second branch's umbrella frame 8 also has proximally and distally, and the second end of its near-end and hold-down bars 6 is longitudinally slidably
Connection and distal end then extends towards umbrella top and is fixedly connected with corresponding main umbrella skeleton 9.Second branch's umbrella frame 8 can also form circle
Bar-shaped, length can be 6em or so.First branch's umbrella frame 7 and second branch's umbrella frame 8 can be by shape memory alloy elastic materials
It is made.
First branch's umbrella frame 7, second branch's umbrella frame 8 compared with the tie point of main umbrella skeleton 9 is more adjacent with the tie point of main umbrella skeleton 9
Nearly umbrella top, so that the tie point of first branch's umbrella frame 7 forms the tie point formation second of the first inner ring and second branch's umbrella frame 8
Outer ring.40 ° or so of angle can be formed between first branch's umbrella frame 7 and hold-down bars.
Second end of hold-down bars 6 is circumferentially spaced nearby to be provided with multiple longitudinal directions chute (not specifically illustrated) to receive accordingly
Second branch's umbrella frame 8 near-end.Longitudinal direction (diagram above-below direction) can be provided with a series of stop mechanisms on each chute
The near-end of second branch umbrella frame 8 of such as groove footpath narrowing portion 12 with backstop slip so far.In this case the second branch's umbrella frame 8
Near-end can be preferably formed into expansion-head structure such as hemispherical head.Longitudinal chute is preferably arranged to be formed in solid hold-down bars 6
Blind slot in circumferential wall, to avoid that Entanglement occurs between the regulation line 1 that will be described below.
The near-end of second branch's umbrella frame 8 is adjusted for convenience along the longitudinal sliding motion of hold-down bars 6, can adjust lines 1 using multiple,
Each regulation line 1 one end be connected with the near-end of second branch's umbrella frame 8, the other end then extend pass can umbrella 5 umbrella top
Opening and tubular support 3 hollow channel.For the damage for preventing from adjusting the distribution of line 1 and being likely to result in alimentary canal
, can be housed in the major part (refer to its length for) of these regulation lines 1 in a flexible pipe 11 by wound.
As shown in figure 3, line traffic control memory umbrella of the invention can also include can remove sleeve pipe or can extract jacket casing 2, its overcoat
In can maintain it in closed mode or contraction state on umbrella 5 and tubular support 3, and be automatically releasable after being extracted can
Umbrella 5 and tubular support 3 are forming it into open mode or swelling state.It will be appreciated by a person skilled in the art that also may be used
Discharged with using any other suitable method can umbrella 5 and tubular support 3 to form it into opening or swelling state.
Use and the course of work of line traffic control memory umbrella of the invention is briefly described below down.
First, the device with jacket casing 2 is sent near gastral stomach bottom 60 via oral cavity or nasal cavity, through x lines or bed
Other ultrasound extracts jacket casing 2 out after determining position, at this moment tubular support 3 and can the automatic expansion of umbrella 5 or normal opening (refer to
Shown in Fig. 4), due to connecting the relative decrease external diameter of transition part 4, whole device is just fixed or is positioned at esophagus 50 and stomach bottom 60
Relevant position, and pressure hemostasis is carried out to cirso- herein.Because whole device is formed with run through up and down hollow logical
Road, therefore at this moment still can perform other inspection such as gastrocopies.In addition, hemostasis device of the invention even can be subsequent
Short-term being retained in patient's body continues its anastalsis without influenceing its normal life.
As shown in figure 5, if necessary to adjusting means to somewhere pressure applied near stomach bottom, just pulling up corresponding
Regulation line 1, so as to drive longitudinal chute that the near-end of second coupled branch's umbrella frame 8 is set along the excircle of hold-down bars 6
Upward sliding, until with required pressure respective heights at groove footpath narrowing portion 12 and by its backstop in this place.
Additionally, as shown in fig. 6, can respectively be adjusted by adjusting different regulation lines 1 successively can be around the umbrella cover of umbrella 5
The pressure in multiple orientation, approximately laminating presses completely to make cirso- of the whole umbrella cover to stomach bottom mucous membrane surface, is filled so as to reach
Divide anastalsis.
