Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Embodiment 1:
A kind of foreign body in bladder extractor as shown in Fig. 1~2, including spring 1, outer layer of polyethene 2
And polyethylene inner layer 3.
The outer wall of spring 1 covers outer layer of polyethene 2, is formed between spring 1 and outer layer of polyethene 2
Outer fused layer;The inwall of described spring 1 covers polyethylene inner layer 3, described spring 1 and polyethylene
Endomixis layer is formed between internal layer 3;Outer fused layer and endomixis layer are integral type structure.Described spring
The integrated helical structure in portion 1, has toughness and mobility, has good when physical operation
Load-bearing property and fracture resistance.Spring 1 wraps between outer layer of polyethene 2 and polyethylene inner layer 3,
Spring is wrapped completely by outer fused layer with endomixis layer, makes connection more secure rigid, it is to avoid spring
Portion 1 directly contacts body tissue mucosa and causes damage, improves the safety of operating process.
One end that outer layer of polyethene 2 and polyethylene inner layer 3 stretch out spring 1 in the same direction is also soft after melted
Jointly wrap magnetic metal body 5 after change, make magnetic metal body 5 and outer layer of polyethene 2 and polyethylene inner layer
3 firmly connect, difficult drop-off.Described magnetic metal body 5 is spherical structure, and magnetic metal body 5 is at least
There is half surface exposure outside the port of outer layer of polyethene 2 and polyethylene inner layer 3.Exposed at polyethylene
The surface of the magnetic metal body 5 outside layer port looks at lower suction that can be good straight by localization by ultrasonic or chamber mirror
Attached chamber in-vivo metal foreign body, by natural tract more preferable, more natural be taken out, greatly reduce
The operability being taken out by otch.Outer layer of polyethene 2 and polyethylene inner layer 3 are through melted after-tack
After wrap one end of magnetic metal body 5, make magnetic metal body 5 firmly be connected with polyethylene layer, be difficult to
Come off;And there is certain distance between spring 1 and magnetic metal body 5, it is to avoid spring 1 with
Magnetic metal body 5 produces 90 ° of angles, prevents the situation that fractures from occurring, and extractor is autologous around flexibility
Reaching 360 °, steering capability is effective with suppleness, it is not necessary to seal wire can pass through each physiology of human body voluntarily
Bending, decreases operation cost and unnecessary operation.
The lateral wall of described outer layer of polyethene 2 covers hydrophilic coating film layer 4.With hydrophilic after moistening of water
Property coating layer 4 has extremely strong lubricity, also can be changed into superslide type when encountering sufferers themselves's body fluid
Conduit, adds the lubricants such as paraffin oil entering internal need not.
Clinical practice example:
Clinical data: patient male, 21 years old age, professional student.Marriage situation: unmarried.Foreign body
Title: ferromagnetism steel ball, from glutinous agglomerating, it is impossible to delamination.Diameter 5mm, quantity 125.Main
Tell: include foreign body in bladder voluntarily in 1 week.Clinical symptoms: lower abdomen pendant pain is uncomfortable, the omnidistance gross hematuria of companion,
Dysuria.Foreign body inserts reason: console oneself.Diagnostic method: medical history combination, plain abdominal radiograph, ultrasonic
Inspection, CT.
Foreign body in bladder extractor using method 1:
Inserting bladder with after water lubrication foreign body in bladder extractor through urethra, magnetic metal body 5 is ultrasonic fixed
The lower adsorbing metal foreign body in position, slowly extracts foreign body in bladder extractor, and metallic foreign body together withdraws from bladder,
Easy and simple to handle, non-invasive.
Foreign body in bladder extractor using method 2:
1) insert No. 22 cystoscope epithecas to support;
2) direct-view of F7 ureteroscope inserts foreign body in bladder extractor under guiding, and utilizes bladder different under direct-view
The magnetic metal body 5 suction of foreign body steel ball of thing extractor is outer to be drawn, because magnetic action becomes to alter taking-up
Magnetic steel ball.
3) altogether take out 125 magnetic steel balls, within time-consuming 10 minutes 30 seconds, exhaust.
End of operation, peace returns ward, without any discomfort sense.Give second day to leave hospital, follow up a case by regular visits to all be as good as
Often.
Below preferred embodiment to the invention is illustrated, but the invention is also
Being not limited to described embodiment, those of ordinary skill in the art are without prejudice to the invention spirit
Modification or the replacement of all equivalents, these equivalent modifications or replacement can also be made under premise all comprise
In the application claim limited range.
