Abstract
The utility model belongs to a cytological sampling tool in the biomedicine field, and particularly relates to a sleeve brush used for esophageal cytological sampling. The sleeve brush consists of an outer sleeve and an inner long brush penetratingly sleeved inside the outer sleeve, and the inner long brush consists of a tail section and a head section with an annular nylon brush. The sleeve brush mainly resolves technical problems that the existing esophagofiberscope examination method needs special and expensive equipment, a cytological examination esophageal abrasive balloon method is more complex in operation process, needs to charge and discharge air for an abrasive balloon, is easy to cause sampling surfaces of esophagi to bleed due to over high locally applied pressure and the like. The sleeve brush is low in cost, simple in manufacturing process, safe and reliable in property and high in cell sampling quantity, and seldom damages local tissues. In addition, the outer diameter of the sleeve brush is similar to that of a common stomach tube, and then the sleeve brush does not increase swallow difficulty of patients.
Description
Technical field
This utility model belongs to the cytology's sampling instrument in the biomedical sector, particularly a kind of cover tube brush that is used for the esophageal cytology sampling.
Background technology
The esophageal carcinoma is a kind of fatal disease, and the operation difficulty is big, and prognosis is relatively poor.Early diagnosis is to improve survival rate, reduces the key of operating difficulty.Method of early diagnosis commonly used at present comprises fiberesophagoscopy and draws in the net cytology's check.The former is a kind of direct-view inspection method, needs special, expensive equipment; The latter is cheap, but the patient includes difficulty in to it, and operating process is complicated, needs the action of inflating, exit of net capsule, and too high because of local applied pressure easily, causes the esophagus face of taking a sample hemorrhage.
The utility model content
This utility model provides a kind of cover tube brush that is used for the esophageal cytology sampling, it mainly solves existing fiberesophagoscopy method and needs special, expensive equipment, and it is complicated to draw in the net the operating process of cytology's method of inspection, need the action of inflating, exit of net capsule, and it is too high because of local applied pressure easily, cause technical problems such as esophagus sampling face is hemorrhage, this sampling instrument is with low cost, manufacturing process is simple, performance is safe and reliable, the cell sampling amount is big, and less to the local tissue damage chance.In addition, cover tube brush external diameter and general stomach tube are similar, can not increase the patient and swallow difficulty.
For achieving the above object, the technical solution of the utility model is:
A kind of cover tube brush that is used for esophageal cytology sampling is characterized in that it is made up of the trocar sheath and the interior long brush two parts that can be set in the trocar sheath, described in the long head section formation that is brushed with rear and has annular nylon bristle.
The described cover tube brush that is used for the esophageal cytology sampling is characterized in that trocar sheath is a hollow hoses, and interior long brush length is greater than the length of trocar sheath.
The described cover tube brush that is used for the esophageal cytology sampling, long brush section is bifilar winding arrangement in it is characterized in that, rear is an elementary wires; The head section has the hair brush structure that bifilar winding tinsel clamping multi beam annular nylon yarn forms.
The described cover tube brush that is used for the esophageal cytology sampling is characterized in that trocar sheath is a silica gel hose, transverse section external diameter 0.5～0.8cm, pipe thickness 0.2～1mm, sleeve pipe total length 20～80cm; Interior long brush length overall=trocar sheath+50cm, a segment length is 1～10cm.
The utlity model has following advantage:
1, this utility model cover tube brush of being used for esophagus exfoliative cyte samplings can help the operator to obtain the esophageal cytology specimen of sufficient amount easily, to satisfy the requirement of suspicious focus being carried out test chamber check and pathological diagnosis.
2, sampling instrument of the present utility model is with low cost, and manufacturing process is simple, and performance is safe and reliable, and the cell sampling amount is big, and less to the local tissue damage chance.In addition, cover tube brush external diameter and general stomach tube are similar, can not increase the patient and swallow difficulty.
Description of drawings
Fig. 1 is the structural representation one (be in resting state, interior long brush is not drawn as yet) of this utility model cover tube brush.
Fig. 2 is the structural representation two (in running order, interior long brush is drawn, can take a sample) of this utility model cover tube brush.
The specific embodiment
See also Fig. 1-2, the utility model discloses a kind of cover tube brush that is used for the esophageal cytology sampling.As shown in the figure: it is made up of trocar sheath 1 and interior long brush 2 two parts that can be set in the trocar sheath 1, and described interior length brush 2 has rear 21 and has head section 22 formations of annular nylon bristle 23.
Trocar sheath is a silica gel hose, transverse section external diameter 0.5～0.8cm, pipe thickness 0.2～1mm, sleeve pipe total length 20～80cm.In long brush be divided into two sections, rear and head section, length overall=trocar sheath+50cm.Segment length is that 1～10cm is the bifilar helix tinsel, twines mutually, and the centre sandwiches nylon yarn, makes it to become nylon bristle.Nylon yarn is a circulus, after the tension, measures its basilar part that links to each other with tinsel and should be 1～3cm to the length between the free-end.Rear is an elongated metal wire, and diameter is less than 1mm, and rear length=interior length is brushed a length overall-segment length.During assembling, interior long brush is inserted trocar sheath, and head end is just covered in by trocar sheath, promptly get and overlap tube brush.
During use, will overlap tube brush and insert, advise patient's swallowing act from nose, will overlap tube brush swallow into, after direct motion enters 45～55 centimetres, as required, drive in the wrong direction and to pull out cover tube brush number centimetre to tens of centimetres, reach required sample plane.During sampling, earlier the interior relatively tinsel of trocar sheath is retreated 1～10cm, should estimate suitable backway this moment according to the nylon bristle physical length, so that make hairbrush expose the trocar sheath top fully.Then, hairbrush relies on self rigidity, is close to the esophagus inner face, and scrapes by vertical circulus and to get the epithelium of esophagus pull-up cell that falls.For the abundance of taking a sample, but operator's fixed jacket pipe is motionless, back and forth long the brush for several times in the pulling.Treat the sampling finish, the operator can with interior length swishing sound go out part so that nylon bristle returns in the trocar sheath, will overlap tube brush then and pull out in the lump.
Nylon bristle after the sampling is placed container, with the cell-preservation liquid flushing for several times, promptly obtain the required esophagus exfoliative cytology sample of clinical examination.
Embodiment
Get a diameter 1mm stainless steel silk, 135cm.With the head end inflection, two sections stainless steel silks twine mutually, and the centre sandwiches annular nylon yarn multi beam, long brush in becoming.Other gets an external diameter 0.8cm, internal diameter 0.6cm silica gel tube, and long 80cm is as trocar sheath.Interior long brush is inserted trocar sheath, submerged in the trocar sheath in the hairbrush top, promptly get the esophageal cytology drive pipe and brush.
