Description
Technical field
The utility model belongs to surgical instrument sheath technical field, and in particular to a kind of sheath method for endoscope.
Background technique
Medical endoscopes sheath is a kind of important form of endoscope sheath practical application.Specifically, endoscope sheath by
It is investigated as body operation wound formula percutaneous passage sheath, body operation hurtless measure formula nature channel sheath, people's intracorporeal organ channel branch
Frame sheath, arteriovenous sheath, tissue expander etc..
It is hydrophilic coating endoscope sheath in the prior art, hydrophilic coating ureter conveying sheath, ureter push sheath, opaque
Ureter sheath, transparent ureter sheath, puncture outfit, fascia dilator, can the ring-like soft sheath of bending ureteroscope and other hands
For the ureterorenoscope sheath of art instrument using generally, various sheath heads are that the cast opening of flat mouth and various sheath heads are open and tube wall side
Face is 90 °, the thickness of pipe wall of ureter sheath is 0.25mm, ureter sheath inner core expander front end is taper F6 gradual change to coarse.
Wherein, one sheath of indwelling passes through for endoscope and drains various liquid, ureter sheath when ureter sheath operates
Tube body can form certain bending.There is loop type metal in ureter sheath tube body wall, needs to be added in the preparation in sheath tube wall.System
It needs to be added some hydrophilic coating materials when standby ureter sheath and needs a guidance on ureter sheath tube wall, and in ureter sheath
Inner core expander could be used in art, prepare disposable ureter sheath surgical instrument higher cost.Therefore, so that surgical device

S1.1 chooses stainless steel pipe according to the thickness and outer diameter of required first sheath 1, will be to be processed by transmitting device
Stainless steel pipe is transported in mold, the length of the stainless steel pipe to be cut transmitted is measured, when the stainless steel tube transmitted
When material length reaches the length of needs, stops transmission stainless steel pipe, drive cutter to rotate using driving device and push cutter
Stainless steel pipe to be cut is cut, primary tubing is obtained；
S2.2 is clamped with the primary tubing that clamping device comes to conveying, then using high speed bit in primary tubing
Corresponding clock position beat location hole 4, and will be worn into an inclined-plane and closed up at primary tubing front end 1mm with sander, can obtained
To the first sheath 1.
S2, the second sheath 2 of production
S2.1 selects corresponding second sheath, 2 mold according to the second sheath 2 of required thickness and outer diameter, by polypropylene original
Material starts plasticizing forming in 2 mold of the second sheath of high fever, forms required 2 formed pipe of the second sheath, and gradually plasticizing is formed
2 formed pipe of the second sheath keep 140-200s in 2 mold of the second sheath, the present embodiment preferably remains 200s；Then from
The outlet end of two sheaths, 2 mold, which pushes, to be squeezed out, when the 2 formed pipe pipe range of the second sheath of extrusion reaches established standards, cutting machine
2 formed pipe of the second sheath is cut off in structure starting；Wherein, 2 mold of the second sheath be infundibulate, pp material in high fever second
Infundibulate pipe is formed after 2 mold of sheath.
S2.2 is clamped 2 formed pipe of the second sheath with clamping device, then using high speed bit the second sheath 2 at
Location hole 4 is beaten in the corresponding clock position of type pipe, and an inclined-plane is worn into the front end of 2 formed pipe of the second sheath with sander, finally
Axis direction with dotted line cutter along 2 formed pipe one end of the second sheath cuts several tear lines 5, and the second sheath can be obtained
Pipe 2.
S3, sheath connection
The tear line 5 of second sheath 2 is opened, and one end of the first sheath 1 is inserted in the tear line 5 of the second sheath 2
It tightens, can be obtained for endoscope sheath.
First sheath 1 and the second sheath 2 are respectively adopted two kinds of different materials and are made, and tube body can be by correspondingly sized at present
Rigid endoscope, have space of corresponding size between endoscope outer diameter and internal diameter of tube body.It is first peeped interior using tube body needs
Mirror is placed in tube body, is observed when entering, and could be placed in the various cavities of human body and be performed the operation in endoscope embedded tube body, hand
It needs to move back mirror in surgical instrument pipe when meeting obstructions in art and examine.It can be used between the various model calibers of the tube body
The use nested against one another of the tube body of close size.First sheath 1 and preferred 3 angle design of inclined surface of the second sheath 2, can be improved
Pipe sheath body cavities stenosis percent of pass, design and the second sheath 2 funnel-shaped design, make pars infundibularis rear end big
It is also that the close formation of the size between two pipes is made to play seamless form that tube head energy and outside internal diameter of tube body front end, which closely connect, into
PA tube is not easy to scratch tissue reduction damage when entering human body.
Application method of the utility model for the sheath of endoscope can select different shaped according to the concrete condition of operation
Number and the sheath of quantity be combined with each other, as shown in Figure 1, No. 15 pipes of the first sheath can be connected with No. 25 pipes of the second sheath to be made
With.The front end of sheath is located in bladder after connection, when operating using Flexible ureteroscope, can drain flushing liquor and a left side in bladder
The urine of right side ureter discharge, when exiting other instrument tubes, still retains the first sheath 15 to reduce the effect of bladder pressure
Number pipe and No. 25 pipes of the second sheath in bladder, can be convenient endoscope carried out in bladder operation treatment use.As shown in figure 5,
First sheath 1 and the second sheath 2 of the utility model can be connected with each other as needed and be applied in combination, when operation, the funnel in outside
Second sheath 2 of type is placed in bladder, and the second sheath 2 of inside is placed in ureter, and endoscope can be in the first sheath 1
Sem observation is inside moved back, and segmentation can be drained to the urine of intravesical flushing liquor and the discharge of left and right sides ureter.
Above description is the detailed description for the preferable possible embodiments of the utility model, but embodiment is not limited to
The patent claim of the utility model, the same changes or modifications completed under technical spirit suggested by all the utility model
Change, should belong to the covered the scope of the patents of the utility model.
