Description
Technical field
The present invention relates to a kind of tissue attemperator, more particularly to a kind of electrothermal in vitro tissue attemperator.
Background technology
Esophagectomy is a kind of important means of esophageal carcinoma therapy, the quality of life later in order to ensure patient, is needed
Esophageal reconstruction is carried out after Esophagectomy.That is, in resection operation, other tissues close with oesophagus construction in human body are chosen, is adopted
With or cut a portion, make and coincide after tubulose to oesophagus end, form new tubular tissue, this tubular tissue can
Replace original oesophagus function, making that patient is postoperative being capable of normal life and work.
In esophageal reconstruction operation, the tissue close with oesophagus construction for being adopted is mainly selected from stomach, colon, jejunum etc..
Wherein, stomach is closest with oesophagus, therefore stomach tissue is using most esophageal reconstruction materials.In stomach tissue, can be with
Mainly there are two kinds as esophageal reconstruction material, full stomach and gastric tube.Wherein, esophageal reconstruction is being carried out as material using full stomach
Post operation, because stomach major part is moved to thoracic cavity, patient is susceptible to after surgery chest dilatation of the stomach, hyperchylia, food retention etc.
Situation, and adopt gastric tube then can reduce above-mentioned situation generation, therefore tubulose stomach oesophagus in recent years with the structure of member-retaining portion stomach
Reconstruction has become a kind of Main Means of cancer of the esophagus operative treatment.
In the operation of gastric tube esophageal reconstruction, doctor needs first the stomach for having dissociated to be carried out into cutting, does gastric tube shaping, is
Bleeding and the tubulose gastric fistula of postoperative incisxal edge are avoided, sewn reinforcement incisxal edge is needed, in this operating process, gastric tube is exposed to abdominal cavity
Outside, tissue temperature is lost quickly, and tissue is substantially in a low-temperature condition after operation terminates, and may cause part gastric mucosa
Need to be incubated in surgery after the completion of necrosis, therefore gastric tube shaping.
At present, the common practice of doctors is to quickly complete operation, reduces and loses the warm time；In minority case, doctor chooses
Suitable container, contains into a certain amount of warm water, gastric tube is placed in this embodiment and by warm water submergence, to ensure that gastric tube is in
In the liquid environment of proper temperature.This way there is also certain defect, because this kind of container is common medical metal container,
There is no heat insulation function, holding warm water temperature therein will soon reduce, and the temperature for causing gastric tube therein also drops quickly
It is low.And temperature is less than after body temperature, the microcirculation in vitro tissue can be affected so as to middle generation capillary blocking, supply
Blood is not enough or even necrosis phenomenon；Such gastric tube is seamed to after new oesophagus, also easily causes blood supply bad, identical
Mouth fistula, or even the problems such as necrosis, affect the prognosis of Gastric transposition reconstruction operations.

Silica gel heating sheet 123 is controlled.
The method of above-mentioned control is mainly：When the temperature of electric heating layer 12 is less than the first setting value, silica gel heating sheet 123
Work is simultaneously heated to electric heating layer 12, now organizes the temperature of placed layer 11 also to increase；The temperature of electric heating layer 12
During higher than the second setting value, the silica gel heating sheet 123 quits work, and now organizes the temperature of placed layer 11 also to top out.
So that the temperature of electric heating layer 12 and tissue placed layer 11 is maintained all the time between the first setting value and the second setting value, its
In first setting value deduct certain numerical value for set temperature value, the second setting value is that set temperature value adds the fixed number of identical one
Value；The occurrence of the certain numerical value can be default according to temperature controlled required precision, typically between 0.2～2 DEG C.
The attemperator 100 of the present embodiment need to extract lead connector 25 from lead connector 122 before sterilization,
Lead connector is covered tightly with lead connector closure, then by the overall disinfection of insulation portion 10.After sterilization, insulation portion 10 can bring into
Operating room, organizing can pour physiological saline or the water purification through sterilization in placed layer 11, the insertion lead connection of lead connector 25
After mouth 122, plug in, the preheated one-section time, can be used to be incubated in vitro tissue after temperature stabilization.
The operations such as sterilization, preheating should be carried out in advance, so as to can at once be put into the physiological saline or water purification of proper temperature after tissue is in vitro
In.
Embodiment is acted on and effect
In the attemperator that the present embodiment is provided, insulation portion has electric heating layer, and the electric heating layer can be to organizing placed layer
Heated, control unit can be controlled to the silica gel heating sheet in electric heating layer, make electric heating layer be maintained at certain limit
It is interior, therefore the in vitro tissue can be incubated when organizing and placed in vitro tissue in placed layer, make the temperature of in vitro tissue
It is maintained within a certain range, it is to avoid the problems such as capillary blocking, blood supply insufficiency occur.Control unit is connected with insulation portion by lead
Joint and cooperating for lead connector carry out connection, the lead connector and lead connector it is detachable with being combined into
Connection, therefore insulation portion can carry out high-temperature sterilization or sterilization liquid disinfectant as single structure, and operation can be brought into after sterilization
Used in the clean environments such as room.This separate structure is prevented from circuit or the component damaged in control unit when sterilizing.
Additionally, in the present embodiment, tissue holds the corner of layer inwall and is smooth arc, therefore is not easy residual stains,
It is easy to clean and sterilizes；The length, width and height size of insulation portion is suitable, and tissue holds layer can accommodate the gastric tube for cutting；Also, protect
Warm portion's overall volume is less, can be placed in surgical console.
<Embodiment two>
In the present embodiment two, for the identical structure of embodiment one, give identical symbol, and omit identical and say
It is bright.
Fig. 4 is the insulation portion structural representation of the embodiment of the present invention two.
As shown in figure 4, in the present embodiment, insulation portion 10 is split-type structural.I.e., placed layer 11 and electric heating layer are organized
12 is separable, and the two length and width is equal.The top corner of electric heating layer 12 is respectively arranged with four projections 125, tissue
The bottom corner of placed layer 11 is correspondingly provided with groove (not shown), the projection 125 and groove fit, places tissue
Layer 11 and electric heating layer 12 can be assembled together.
Embodiment is acted on and effect
In the present embodiment, insulation portion is split-type structural, and tissue placed layer and electric heating layer are separate, organize placed layer
High-temperature sterilization can be individually carried out, the replacing of temp probe, silica gel heating sheet in electric heating layer is also more convenient.
