Description
Technical field
This utility model belongs to flexible ureteroscope and sends to sheath.
Background technology
At present in flexible ureteroscope operation process, in order to facilitate mirror body turnover renal pelvis aggregation system and at transluminal operation, and facilitate the removing of calculus fragment, generally acknowledged mode is to adopt flexible ureteroscope to send to sheath.As shown in Figure 1, sheath core 21 is made up of end 25 in sheath core stop 23, sheath core body 22, the outer end 24 of sheath core body and sheath core body.On sheath core stop 23, be provided with sheath core stop switch 26.Sheath core 21 is made up of flexible material, be provided with in the inside of sheath core 21 one from sheath core body end 24 to the safety guide wire passage 27 of end 25 in sheath core body, for preset safety guide wire.But, above-mentioned flexible ureteroscope is sent to sheath and is mainly made up of sheath body and sheath core, its mesotheca body is simple elongate tubular structure, can only the calculus fragment in renal pelvis be transferred in the mode of passive attraction externally, cause often occurring that calculus fragment drainage efficiency is low, calculus fragment cannot be removed the occurred frequently of clean and perioperative infection complication in operation process.
Utility model content
The purpose of this utility model is to provide a kind ofly to be had the soft ureter of negative pressure that controlled active attracts and sends to sheath, and while having solved existing flexible ureteroscope rubble operation, low, the calculus fragment of calculus fragment drainage efficiency cannot be removed clean and perioperative infection complication problem occurred frequently.
The technical solution adopted in the utility model is as follows:
A kind of negative pressure flexible ureteroscope is sent to sheath, comprise with the sheath core of sheath core stop with the sheath body of sheath core limited post, external week of sheath is provided with negative pressure cabin, its one end is connected with sheath core limited post, sheath body is positioned at one end of negative pressure cabin inside sealing cap is installed, itself and sheath body and negative pressure cabin closely agree with, the other end of negative pressure cabin and sheath core limited post are tightly connected, negative pressure cabin is provided with one can connect negative pressure suction device vacuum suction interface, sheath body is provided with hole, equally distributed sheath side near one end of sheath core limited post, and negative pressure cabin is provided with a pressure control hole.
In operation process, start negative pressure suction device, from renal pelvis to sheath body, from sheath body, again to negative pressure cabin, from negative pressure cabin to negative pressure suction device, pressure is from high to low, has formed active vacuum suction from inside to outside.Calculus fragment flow to sheath body inside from renal pelvis under this active vacuum suction, is collected in negative pressure cabin through hole, sheath side, effectively raises the drainage efficiency of calculus fragment, effectively reduces renal pelvis internal pressure and perioperative complications simultaneously and occurs.
As further improvement of the utility model, it is I-shaped that sealing cap is radially, and is axially hollow structure, and this structure main purpose is when ensureing seal, to increase passability.
As further improvement of the utility model, the diameter in hole, sheath side is 2-4mm, and distribution is that interval 2-2.5mm is distributed in sheath body surrounding, effectively raises the drainage efficiency of calculus fragment, effectively reduces renal pelvis internal pressure simultaneously.
As further improvement of the utility model, this hole openings of sizes, by finger presses, is controlled in pressure control hole, controls the size of negative pressure and has or not, and the control of negative pressure depends on the size in pressure control hole.Effectively raise the drainage efficiency of calculus fragment, effectively reduce renal pelvis internal pressure simultaneously.
As further improvement of the utility model, sealing cap is quality of rubber materials, and sheath body is flexible plastic material, and negative pressure cabin is hard transparent plastic material, with low cost.
As further improvement of the utility model, sheath core limited post, sealing cap, front end, middle-end and the end of sheath body, adopted different colors, convenient from work screen judgement mirror body position, mirror body can be judged the particular location in sheath, handled easily by color in movement.

Detailed description of the invention
Referring to accompanying drawing 2, a kind of soft ureter of negative pressure with controlled attraction is sent to sheath, is made up of negative pressure cabin 31, sheath body 11 and 21 3 parts of sheath core.Negative pressure cabin 31 is made up of hard transparent plastic, and length is 5cm, and diameter is 2.5cm.Sheath body 11 is plastic flexible pipe, and Fr34-31(Fr is surgery conventional unit, represents Zhou Jing, 1Fr=0.3mm), sheath body total length 40-50cm, the wherein long 35-45cm of exposed parts.
As shown in Figure 2, negative pressure flexible ureteroscope is sent to sheath, comprise with the sheath core 21 of sheath core stop 23 with the sheath body 11 of sheath core limited post 12, the periphery of sheath body 11 one end is provided with negative pressure cabin 31, one end of negative pressure cabin 31 is connected with sheath core limited post 12, sheath core limited post 12 is rigid plastics material, discoid, and diameter is 3cm.Sheath body 11 is positioned at one end of negative pressure cabin 31 inside sealing cap 33 is installed, and itself and sheath body 11 and negative pressure cabin 31 closely agree with.The material of sealing cap 33 is rubber-like, is radially I-shaped, is axially hollow structure, and the mirror body that holds flexible ureteroscope when ensureing seal enters sheath body 11.Negative pressure cabin 31 is reinforced and is kept sealing by fluid sealant near one end of renal pelvis and the connecting portion of sheath body 11.The middle part of negative pressure cabin 31, is provided with vacuum suction interface 32, for connecting the negative pressure suction device of operating room central authorities.Sheath body 11, is positioned at negative pressure cabin 31 interior sections, is distributed with hole, 5 sheath sides 34, and the optimum diameter in hole, sheath side is 3mm, and Optimal Distribution state is that interval 2mm is distributed in sheath body surrounding.Negative pressure cabin 31 is provided with a pressure control hole 35, and it is positioned at the region, opposite of vacuum suction interface 32, and diameter is 0.8cm, by finger control pressure control hole perforate size, while pressing off completely, be peak suction state, when completely open, negative pressure disappears, and pressure size determines by pointing sealing area.Hole, sheath side 34 allows fluid freely to come in and go out.
In operation process, first sheath core 21 is inserted to sheath body 11, sheath body 11 is inserted renal pelvis along safety guide wire.Take out after sheath core 21 the inner service aisle that forms the flexible ureteroscope to Ureteropelvic junction position from external orifice of urethra of sheath body 11.Mirror body is inserted renal pelvis by the inner passage of sheath body 11 from external orifice of urethra, carries out rubble operation.
In rubble operating process, operator are connected to the negative pressure suction device of operating room central authorities on vacuum suction interface 32, the voltage-controlled pressure that simultaneously press...withes one's finger hole 35, the pressure decreased of sheath body 11 inside is extremely lower than renal pelvis internal pressure, the pressure differential producing attracts rubble fluid to flow to sheath body 11 inside from renal pelvis inside, finally fall into negative pressure cabin 31 inside along sheath body 11 hole, sheath side 34 of flowing through, complete calculus and collect, the pressure of renal pelvis inside also decreases.
