Abstract
The invention provides a decompression collector. The decompression collector comprises an inner tube and an outer tube which is arranged outside the inner tube in a sleeving mode; the inner tube comprises a channel; a gap which is used for arranging clipped tissue is formed between the inner tube and the outer tube; an elastic object is arranged in the gap; a driving part is matched with the outer tube to drive deformation of the elastic object and accordingly the applied force which is attached to the outer wall of the inner tube can be applied to the tissue. According to the decompression collector, the tissue is compressed through the elastic deformation and accordingly the risk that the tissue is clipped to be broken by an advanced technology is avoided and the use is safe and reliable.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments that is applicable to intestinal obstruction operation, intestinal canal tumour operation, especially a kind of decompression catcher, belongs to technical field of medical instruments.
Background technology
When small intestinal or large bowel obstruction, block near-end intestinal tube and obviously expand, a large amount of intestinal contentses stockpile in intestinal tube, need to be on operating-table, it is emptying during operation, and excision pathological changes is carried out coincideing of intestinal tube.In at present conventional art, the mode of depressing intestinal canal has the depressing intestinal canal that uses suction pump insertion expansion, and the method very easily causes intraperitoneal and operating room severe contamination, and consuming time very long, complicated operation; Another method is for being used decompressor to reduce pressure.The structure of decompressor generally comprises two ends and has the hollow pipe of opening, and a wherein opening of described hollow pipe is for being combined with intestinal, and to receive the ejection of intestinal, ejection, through hollow pipe, enters by another opening receiving in dirty bag of being connected.But existing decompressor design is too simple, operating difficulties, safety is low, during use, block intestinal tube and be combined comparatively difficulty with hollow pipe, easily cause departing from, cause leakage, pollute, lack the simultaneously function of enteroclysis simultaneously, be badly in need of having and more use safety, decompressor simple to operate.
In Chinese patent CN03262061.6 and CN201210006141.5, all disclose a kind of decompression catcher, adopted inner and outer tubes fit structure, first intestinal tube has been placed between the two, then adopted band to be fixed.It is cumbersome that but this band mode operates, and chucking power is also inadequate.
Chinese patent CN93220204.7 and WO2001032239 have disclosed a kind of decompression catcher of new construction, and the fit structure of inner and outer tubes is arranged to be threaded.But because intestinal tube tissue is placed between described inner and outer tubes, therefore, when inner and outer tubes are carried out screw thread clamping, be easy to be caught broken tissue, cause the complication of operation.
Summary of the invention
The object of this invention is to provide one safe and reliable, and be difficult for adding the decompression catcher of broken tissue.
Object of the present invention, will be achieved by the following technical programs:
A kind of decompression catcher, comprise: inner tube and be sheathed on the outer tube outside described inner tube, described inner tube comprises a passage, between described inner and outer tubes, be provided with for arranging by the gap of folder tissue, in described gap, be provided with an elastic, there is an actuator to coordinate with outer tube and order about described elastic distortion, and then tissue is applied to an active force that is adjacent to described outer wall of inner tube.
Preferably, described actuator is knob, and the external screw thread of described knob is threaded with the female thread of described outer tube.
Preferably, described outer tube comprises a step, and described elastic is arranged between the step surface of described step and the end face of described knob.
Preferably, described elastic is rubber ring.
Preferably, the outer wall of described inner tube is provided with wave projection.
Beneficial effect of the present invention is mainly reflected in: adopts strain compressed tissue, avoided being caught broken the risk of tissue, and safe and reliable.
Accompanying drawing explanation
Fig. 1 is the reduce pressure cutaway view of preferred embodiment of catcher of the present invention.
The specific embodiment
The present invention has disclosed a kind of decompression catcher, preferred embodiment as shown in Figure 1, it comprises: inner tube 1 and be sheathed on the outer tube 2 outside described inner tube 1, described inner tube 1 comprises a passage 11, described passage 11 with receive a dirty bag (not shown) and be connected also conducting.Between described inner tube 1 and outer tube 2, be provided with for arranging by the gap 3 of folder tissue 4.
In described gap 3, be provided with an elastic 6, have an actuator to coordinate with outer tube 2 to order about described elastic 6 and be out of shape, and then to organizing 4 to apply an active force that is adjacent to described inner tube 1 outer wall.In this preferred embodiment, described actuator is knob 5, and the external screw thread 54 of described knob 5 is threaded with the female thread 24 of described outer tube 2.Described elastic 6 is rubber ring.Described outer tube 2 comprises a step 23, and described rubber ring is arranged between the step surface of described step 23 and the end face of described knob 5.
During operation, the inwall of tissue is placed on to the outside of described inner tube 1, the outer wall of tissue is placed on the inner side of described outer tube 2 simultaneously, doctor props up the end face 22 of outer tube 2 on the other hand, another hand-screw turns described knob 5, knob 5 can move relative to described outer tube 2, and the end face of described knob 5 can be oppressed described rubber ring and be made its distortion.Because the position of described outer tube 2 is relatively fixing, so the rubber ring of distortion can produce an active force that orders about described tissue 4 and be adjacent to described inner tube 1 outer wall, tissue is fixed in gap 3.In this process, screw thread can directly not contact with tissue, therefore just can not produce the risk that is caught broken tissue, and elastic 6 is also difficult for tissue to cause damage simultaneously.
Further, the outer wall of described inner tube 1 is provided with wave projection 15.Can increase like this frictional force of organizing when clamped.
Emphasis of the present invention is at rubber ring elastic clamping structure, therefore such as receiving the connection of dirty bag, the setting of lavation structure, there is no unnecessary description, adopts prior art.For example: the water inlet of lavation structure can be used passage 11, or on the wall of inner tube 1 opening separately.
The present invention still has numerous embodiments, and for example, the mode that actuator coordinates with outer tube 2 is clamping.All employing equivalents or equivalent transformation and all technical schemes of forming, within all dropping on protection scope of the present invention.
