Abstract

The utility model provides a bladder puncture fistulization ware, includes the obturator puncture ware, still includes the pipe of cover setting on the obturator puncture ware, the outer end of pipe with the annular baffle threaded connection of the tail end of obturator puncture ware. Compared with the combination of a sheath and an outer tube in the prior art, the combined type puncture needle has the advantages that the structure is compact, the cost is low, particularly, the circular tube is adopted, the arc hook edge which is similar to the notch in the prior art does not exist, any scraping can not be generated on human tissues, the secondary injury on the human tissues is effectively avoided, the circular tube can follow the obturator puncture needle to go deep into the body synchronously, the problem that the prior art cannot be effectively inserted into the bladder of an obese patient is effectively avoided, and risks in the operation are avoided.

Description

Bladder puncture fistulization device
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to bladder puncture fistulization ware.
Background
The bladder puncture fistulization device used in the medical treatment at present mainly comprises a closed hole puncture outfit 1 with a conical front end, a sheath 2 (the sheath 2 comprises an operation nut 3 at the tail end, a first groove-shaped section 5 connected with the operation nut 3 through a first circular pipe section 4) which can be sleeved outside the closed hole puncture outfit 1, and an outer pipe 6 (the outer pipe 6 comprises a second circular pipe section 7 at the front end and a second groove-shaped section 8 extending backwards from the rear end of the second circular pipe section 7, and the front end of the second groove-shaped section 8 is provided with a notch 9 with a C-shaped longitudinal section) which can be sleeved on the sheath 2, when in use, the closed hole puncture outfit 1 is inserted into the sheath 2 from the rear end and extends forwards to be exposed out of the front end of the sheath 2, the outer pipe 6 is sleeved on the sheath 2 from the front end of the sheath 2, and the outer pipe 6 is rotated to enable the second groove-shaped section 8 to be buckled with the first groove-shaped sheath section 5, and a part of a front end rod piece of the closed hole puncture outfit 1, and the tail end of outer tube 6 inserts the clearance between operation nut 3 and the pipe section 4, accomplish spacing fixed to outer tube 6, so far accomplish the preoperative preparation of bladder puncture fistulization ware, during the operation, when the puncture ware 1 punctures to the internal, sheath 2 and outer tube 6 get into along with it, accomplish the puncture back, outwards extract obturator puncture ware 1, insert the catheter to the internal through notch 9, pull out sheath 2 simultaneously, accomplish the fixed back of inserting of catheter, extract outer tube 6, at this moment, because C type notch 9 has been seted up on outer tube 6, can not avoid causing the hook wound to human tissue, bring secondary injury and misery for the patient, increase postoperative risk. In addition, the notch 9 is formed at the distal end of the outer tube 6, and the sheath 2 and the outer appearance have inherent lengths, so that it is difficult to penetrate into the stoma of a patient with an excessively fat body, and problems such as leakage of urine in the body and difficulty in intubation are likely to occur.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the problems that the existing bladder puncture fistulization device is easy to scratch tissues and cannot directly focus at one time when being pulled out, and the secondary pain of a patient and the operation risk are easily caused by urine leakage.
In order to achieve the purpose, the utility model provides a bladder puncture fistulization device, including the obturator puncture outfit, still establish including the cover pipe on the obturator puncture outfit, the outer end of pipe with the annular baffle threaded connection of the tail end of obturator puncture outfit.
The inner cavity of the tail end of the round pipe is provided with a silica gel sheet with a hole at the center.
The utility model has the advantages that: compared with the combination of a sheath and an outer tube in the prior art, the combined type puncture needle has the advantages that the structure is compact, the cost is low, particularly, the circular tube is adopted, the arc hook edge which is similar to the notch in the prior art does not exist, any scraping can not be generated on human tissues, the secondary injury on the human tissues is effectively avoided, the circular tube can follow the obturator puncture needle to go deep into the body synchronously, the problem that the prior art cannot be effectively inserted into the bladder of an obese patient is effectively avoided, and risks in the operation are avoided.
The present invention will be described in detail with reference to the accompanying drawings and examples.
Drawings
Fig. 1 is a structural schematic diagram of a prior art bladder puncture fistulization device.
Fig. 2 is a structural schematic diagram of a modified bladder puncture fistulization device.
Description of reference numerals: 1. a obturator puncture outfit; 2. a sheath; 3. operating the nut; 4. a first circular tube section; 5. a first trough-like section; 6. an outer tube; 7. a second circular tube section; 8. a second trough-like section; 9. a notch; 10. a circular tube; 11. an annular baffle; 12. a silica gel sheet.
Detailed Description
In order to overcome the problems that tissues are easily scratched and the focus cannot be directly reached at one time when the existing bladder puncture fistulation device is pulled out, urine leakage is easily caused, and secondary pain and operation risk of a patient are caused, the embodiment provides the bladder puncture fistulation device shown in fig. 2, which comprises a closed hole puncture device 1 and a circular tube 10 sleeved on the closed hole puncture device 1, wherein the outer end of the circular tube 10 is in threaded connection with an annular baffle 11 at the tail end of the closed hole puncture device 1. When the puncture outfit is used, the circular tube 10 enters the body of a patient along with the obturator puncture outfit 1, and the existence of the notch 9 similar to that in the prior art does not exist, so that the circular tube can be synchronous along with the insertion depth of the obturator puncture outfit 1, the bladder perforation of an obese patient can be effectively realized, when the obturator puncture outfit 1 is pulled out, urine can flow outwards from the inside of the circular tube 10, the phenomenon of urine leakage in the body can not occur, after the catheter is inserted from the rear end of the circular tube 10, the circular tube 10 is pulled out again, and because the surface of the circular tube 10 is smooth, and two ports are not in contact with the human tissue, the scraping to the human tissue can not be caused, and the secondary damage to the human tissue is effectively avoided.
In order to avoid urine overflowing to the periphery when the obturator puncture instrument 1 is pulled out, the silicone sheet 12 with the central opening is arranged in the inner cavity of the tail end of the circular tube 10, and when the obturator puncture instrument 1 is separated from being in contact with the silicone sheet 12, the central opening in the silicone sheet 12 is closed under the action of self elasticity, so that the urine is sealed.

Claims (2)
