Abstract
The present invention relates to a kind of withdrawing devices suitable in vitro tissue, belong to medicine correlative technology field.Include mainly：The inner wall rear side of annulus, the annulus is fixedly connected with bagging；Outer wall front side and the two flap airtight connections of the annulus；The bagging is between two flaps；The retaining part of one caliper is inside the bagging；Wherein, it is provided with pump orifice on the annulus, which is connected to negative tube.The present apparatus makes it realize sealing and volume compression in vitro tissue in vivo, realizes and do not expand minimally invasive mouth as possible and prevent tissue fluid from being sent out in thoracic cavity or abdominal cavity due to extruding by designing completely new structure.
Description
Technical field
The present invention relates to medicine correlative technology fields, in particular to a kind of taking-up suitable in vitro tissue fills
It sets.
Background technology
For some patientss, abdominal cavity or intrathoracic pathological tissues need to take out after a resection.In the mistake of taking-up
Cheng Zhong, because including more gas and tissue fluid in vitro tissue, so can cause tissue fluid due to extruding in thoracic cavity or abdominal cavity
In send out, there are the widened risks of the state of an illness.
In the prior art, exist and in vitro tissue is placed in bagging, the method for then integrally pulling out it.But when in vitro
When tissue volume is larger, it is necessary to expand wound, this can undoubtedly cause larger injury to patient.
Invention content
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of taking-up dress suitable in vitro tissue
It sets.The present apparatus by design completely new structure so that it can realized in the case of smaller wound sealing in vitro tissue and
Volume compression.
In order to achieve the above objectives, the present invention adopts the following technical scheme that：
A kind of withdrawing device suitable in vitro tissue, including：
The inner wall rear side of annulus, the annulus is fixedly connected with bagging；
Outer wall front side and the two flap airtight connections of the annulus；
The bagging is between two flaps；
The retaining part of one caliper is inside the bagging；
Wherein, it is provided with pump orifice on the annulus, which is connected to negative tube.
Preferably, there are two lug bosses for the front end tool of the bagging.
Preferably, the flap is rubber or silica gel material.
The beneficial effects of the invention are as follows：
Bagging is pulled back after in vitro tissue can be clamped using caliper, the self sealss of flap are realized, in negative tube
The lower bagging inner air of effect and tissue fluid are pumped, and then reduce the volume of bagging and in vitro tissue, are taken out facilitating
While in vitro tissue, minimally invasive mouth is not expanded substantially.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention；
Fig. 2 is the status diagram gripped before in vitro tissue；
Fig. 3 is the status diagram gripped after in vitro tissue；
Fig. 4 is sectional view along A-A in Fig. 3；
In figure：Bagging 1, lug boss 1-1, bag body 1-2, flap 2, annulus 3, pump orifice 4, hard negative pressure pipe 5, caliper 6, from
Body tissue 7.
Specific implementation mode
Below in conjunction with attached drawing, the present invention is described in detail.
Embodiment：A kind of withdrawing device suitable in vitro tissue, structure is as shown in Figure 1, include：Annulus 3, the annulus
It is fixedly connected with bagging 1 on rear side of 3 inner wall；
Outer wall front side and two 2 airtight connections of flap of the annulus 3；
The retaining part of one caliper 6 is in the inside of the bagging 1, and bagging 1 is between two flaps 2 so that two flaps 2
It is softened；
Wherein, it is provided with pump orifice 4 on the annulus 3, which is connected to hard negative pressure pipe 5.
Preferably, the bagging 1 includes bag body 1-2 and two lug boss 1-1 in front of bag body 1-2；Bag body 1-2 and
Lug boss 1-1 is integrally formed.Meanwhile the flap 2 is rubber or silica gel material, has good elasticity.
Before use, the present apparatus is placed in by minimally invasive mouth intraperitoneal.
Refering to what is shown in Fig. 2, in use, using caliper 6 across bagging 1 by 7 firm grip of in vitro tissue.Then, circle is kept
Ring 3 is motionless, then firmly pulls caliper 6 backward, and push annulus 3 forward by hard negative pressure pipe 5, then lug boss 1-1 and bag
Body 1-2 is moved backward both with respect to annulus 3.When caliper 6, lug boss 1-1 and bag body 1-2 not between two flaps 2 when, two
A flap 2 is closed automatically under the action of elasticity, reaches sealing effect, which can refer to shown in Fig. 3 and Fig. 4.
Subsequent start-up negative-pressure ward, the then tissue fluid that the air in bagging 1 and in vitro tissue 7 have are pumped, then cover
The volume of bag 1 reduces, and the volume of in vitro tissue 7 also reduces.
After the completion of suction, the aspiration phases of negative tube are kept, the present apparatus is taken out from minimally invasive mouth.
With the above structure, the present apparatus can it is intraperitoneal complete in vitro tissue closed and tissue fluid suction,
Prevent tissue fluid during in vitro tissue is in taking-up from diffusing and the minimally invasive mouth caused by vitro tissue volume expands can be reduced
Larger defect.
In the present invention, the self sealss effect of two flaps is consistent with the self sealss principle of duckbill valve flap in respirator,
Herein just without repeating.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
A variety of modifications of embodiment will be apparent to those skilled in the art, it is as defined herein general
Principle can be realized in other embodiments without departing from the spirit or scope of the present invention, is not described in detail
The part presented with partial enlargement is the prior art, herein without repeating.Therefore, the present invention is not intended to be limited to herein
Shown in these embodiments, and be to fit to the widest range consistent with principles disclosed herein and feature.
