Description
Technical field
This utility model relates to a kind of bladder stoma apparatus, especially a kind of bladder stoma needle guard part of improvement.
Background technology
In existing human body urinary system, because of urethral obstruction, the bladder on pubis taked makes fistulation, and feelings Condition menisectomy as is taked one-step method to puncture and set up passage, inserts stoma after Path Setup, urine drainage to external, solves the dysuria of patient.In operation process, first patient's filling of bladder, pubis determines point of puncture, after local anaesthesia, the tearable puncture ostomy needle made of metal is aimed at point of puncture on pubis puncture, puncture ostomy needle tail end has Guang wing urine to flow out, and proves that puncture puts in place, then stoma is imported from puncture ostomy needle tail end, tear puncture ostomy needle, the puncture ostomy needle torn is taken out, then inflating balloon, fixing stoma, has performed the operation after connecting drainage bag.But existing fistulation apparatus is comparatively large for the wound of patient, and doctor is awkward.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of bladder stoma needle guard part of improvement, can solve the deficiencies in the prior art, reduce the wound for patient, without fear when doctor operates, improve surgical facilitation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A bladder stoma needle guard part for improvement, comprises sheath pipe, is socketed with convergent divergent channel, is plugged with puncture needle in convergent divergent channel in sheath pipe; Sheath pipe is provided with tearing groove along the axis of sheath pipe, the bottom of convergent divergent channel is provided with point, the top of convergent divergent channel is provided with connector portions, the length of convergent divergent channel is equal with the length of sheath pipe, the bottom of puncture needle is provided with angle portion, and the top of puncture needle is provided with turncap, when turncap to be connected with connector portions coordinate time, angle portion is positioned at the outside of point, is provided with through pod apertures in puncture needle and turncap.
As preferably, described convergent divergent channel coordinates with sheath ligament.
As preferably, the contact site of described point and sheath pipe seamlessly transits.
As preferably, the diameter of described pod apertures is less than 1.2mm.
As preferably, described puncture needle and convergent divergent channel interference fit.
The beneficial effect adopting technique scheme to bring is: can accomplish that patient body brings wound wound little in this utility model operation, without fear when doctor uses, operation is carried out smoothly, alleviate mental pressure to health care workers and bring great convenience for successful surgery, bringing glad tidings to patient simultaneously! For the success of operation provides essential condition.

Detailed description of the invention
With reference to Fig. 1-4, this utility model detailed description of the invention comprises sheath pipe 1, is socketed with convergent divergent channel 2, is plugged with puncture needle 3 in convergent divergent channel 2 in sheath pipe 1; Sheath pipe 1 is provided with tearing groove 4 along the axis of sheath pipe 1, the bottom of convergent divergent channel 2 is provided with point 5, the top of convergent divergent channel 2 is provided with connector portions 6, the length of convergent divergent channel 2 is equal with the length of sheath pipe 1, the bottom of puncture needle 3 is provided with angle portion 7, and the top of puncture needle 3 is provided with turncap 8, when turncap 8 to be connected with connector portions 6 coordinate time, angle portion 7 is positioned at the outside of point 5, is provided with through pod apertures 9 in puncture needle 3 and turncap 8.Convergent divergent channel 2 and sheath pipe 1 matched in clearance.Point 5 seamlessly transits with the contact site of sheath pipe 1.The diameter of pod apertures 9 is less than 1.2mm.Puncture needle 3 and convergent divergent channel 2 interference fit.
Sheath in the present embodiment effective medical polymer material PTFE is made into, and this sheath pipe ensures longitudinal tear only, and what ensure that the smooth safety of stoma inserts bladder, decreases the wound to tissue.Than sheath bore, the slightly little and most advanced and sophisticated medical polymer material seamlessly transitted with sheath pipe makes convergent divergent channel external diameter, the hardness of material is suitable, convergent divergent channel length is equal with tearable vaginal length of tube except tip portion and blank area, so not only to ensure that between tearable vaginal tube with convergent divergent channel seamless coordinates, in turn ensure that one-step method punctures by force intensity, greatly reduce the wound to tissue.Puncture needle is made with metal material, thickness and convergent divergent channel caliber tight fit, its one end is made into angle needle point, needle point exposes convergent divergent channel tip, and the other end has turncap, is tightly spun on and connects on a pipe joint, such making not only ensure that wound during tissue penetration little, when in turn ensure that operation puncturing, accurately locating, successfully creating essential condition smoothly for performing the operation.
Before the start of the surgery, puncture needle 3 after sterilization is good inserts convergent divergent channel 2 and screws, insert sheath pipe 1 together again, constitute a set of novel bladder stoma one step puncture method soap external member like this, in operation process, first patient's filling of bladder, pubis determines point of puncture, after local anaesthesia, with scalpel in point of puncture place broken skin, point of puncture on the puncture needle 3 tip alignment pubis of working good in bladder stoma one step puncture method soap external member is punctured, puncture needle 3 tail end has Guang wing urine to flow out, prove that puncture puts in place, then convergent divergent channel 2 and puncture needle 3 is extracted, after importing stoma from sheath pipe 1 tail end, pulled sheathing canal 1, the sheath pipe 1 torn is taken out, then stoma sacculus is inflated, fixing stoma, perform the operation after connecting drainage bag.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed this utility model.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
