Background technique
Zooscopy is generally required in the past to carry out the intracavitary dyeing of hollow organ or injection, is related to looking at lower hollow organ straight
Puncture procedure.Below by taking mouse is studied as an example: when hollow organ puncture and injection of medicine or dyeing, if hollow organ is in expanded state,
Then point of puncture is preferably grasped, due to cannot be guaranteed that hollow organ is full when puncturing, therefore in hollow organ small volume or
The fixation of point of puncture and depth of needle are difficult to control when emptying, and needle point is only to pierce into tissue wall without penetrating in order to prevent,
It generally requires to be determined by 3 points of the tissues such as three vessel forceps clamping hollow organ wall such as bladders and punctured plane and puncture center,
Again with the other hand carry out puncture procedure, due to can opereating specification be often below 1 square centimeter, operation when two hand hypertelorisms, list
, often there are following problems in slight jitter and the powerful chucking power of vessel forceps when hand operates:
A. hollow organ is damaged --- hollow organ wall is by folder necrosis rupture when clamp hollow organ；Hollow organ wall is very
Poor, when clamp hollow organ, tears hollow organ wall；
B. puncture position deviation is excessive --- three vessel forceps are fixed puncture plane when, it is slight due to operator's hand
Shake, causes the variation of plane, and position is difficult to control when inserting needle；
C. different animal hollow organ wall thickness are different, how accurate inserting needle the problem of.

3, specific operating procedure uses rule to carry out puncturing urethra dyeing and display to the bladder under the non-expanded state of mouse
The injection needle of lattice 1 carries out for open surgery:
1) operation is made adequate preparation, and the visual field appears complete, it is seen that rat bladder is located in lower abdomen pelvic cavity, and bladder is in emptying shape
State, can operations area less than 1 square centimeter.
2) by after puncture outfit adequate disinfection, it is farthest that piston bolt 4 along the second horizontal cut 1-3 is pushed into 1 tail end of distance sleeve
In the vertical cut (V. cut) of position；Since commercially available injection needle needle point is often bevel structure, if therefore puncture be thought of as function, it is necessary to by needle point
Inclined-plane submerges the inside of the bladder wall completely, and the pinpoint inclined plane depth of injection needle is about 1.5-2mm, the rat wing of emptying state
Guang wall thickness is about 1mm, therefore by bayonet lock 6-4 pull-up backward, spring 6-5 is in compressive state at this time, after needle tubing 8 is inserted into inner sleeve 6,
It is inserted after inner sleeve is directed at outer tube 3 again, 8 nozzle of outer tube is stretched out about in the tip position that inner sleeve 6 is inserted to needle tubing 8
At 3mm, bayonet lock 6-4 is unclamped, bayonet lock pushes mandril 6-3 to be inserted into inner sleeve card slot 6-2 under the active force of spring 6-5
Interior, corresponding card slot display mark number is 3 at this time, and the position of inner sleeve is fixed at this time, and length and the inner sleeve of outer tube are stretched
The length summation of outer sleeve portion can expose the needle tubing point position about 3mm of needle tubing 8 just out, i.e., piercing depth is 3mm.
3) it is connect after taking out injection needle from inner sleeve with injection tube body；It aspirates again spare after dyeing liquid.
4) nozzle of suction inlet pipe 1 is placed bladder surfaces by the left hand of operator, and the right hand laterally lacks piston bolt 4 along first
Mouth 1-1 is pulled to the tail end direction of casing 1, and piston bolt 4 is stuck in required vertical cut (V. cut) 1-2, at this time suction inlet pipe nozzle
It is fitted closely with outer tube nozzle with the bladder wall.
5) left hand is affectedly bashful 2 side wall of suction inlet pipe, and the injection needle got ready is inserted by the right hand from the top cap 6-1 of inner sleeve 6, when
The boss of needle stand just with the top cap concave surface mutual added time, the tip portion of needle tubing is perpendicular to fixed pan, in fixed pan
The bladder wall about 3mm is punctured at center, pinpoint inclined plane is also completely into bladder.
6) dyeing liquid is slowly injected, since needle point direction is fixed, paracentesis depth is fixed, and right-hand man is closer, therefore
The right hand is relatively stable when operating, and drug injection dosage is held good.After completing injection, injection needle is exited from pin hole, it will
Piston bolt 4 is pushed into the vertical cut (V. cut) of 1 tail end highest distance position of distance sleeve；Restore atmospheric pressure in suction inlet pipe at this time, the bladder wall will
Automatically it is separated with suction inlet pipe nozzle and outer tube nozzle, end of operation.
As described in above content, if the wall thickness of anticipation animal viscera tissue is 5mm, the injection needle of specification 1 is selected, it will
Mandril 6-3 is inserted into card slot 6, and being pierced into depth at this time is 6mm.
And so on, if the wall thickness of anticipation animal viscera tissue is 18mm, the injection needle of specification 2 is selected, by mandril
6-3 is inserted into card slot 10, and being pierced into depth at this time is 19mm.
It is further to note that with wall thickness, card slot, needle tubing specification, the corresponding relationship only expression one for being pierced into depth
Kind corresponding relationship, specific number are not only limited in above-mentioned list, can be according to different application scenarios, and the ratio such as design is put
The puncture outfit of big or Scaling size.
