Summary of the invention
Present invention aims to above-mentioned not part, it is provided that a kind of puncture sheath assembly.
A kind of sheath assembly that punctures is made up of sheath pipe, puncturing lever and lead sheath bar；Puncturing lever is the stock that head has acute angle, is used for puncturing wall of urinary bladder；Lead sheath bar is the stock of the non-acute angle of head, for sheath pipe being imported urethra or intravesical on the premise of not damaging human urethra tissue；Puncturing lever or lead sheath bar are inserted in the inside of sheath pipe；
The described round bar that sheath pipe is hollow, the outer wall at sheath tube head is provided with head injection capsule, and head injection capsule passes through the Valve controlling that sheath pipe afterbody is supporting, and being connected between valve with head injection capsule has conduit, and conduit is positioned at inside or the surface of sheath tube wall.
The length of puncturing lever is more than or equal to the length of lead sheath bar, and the length of lead sheath bar is more than the length of sheath pipe.
The middle lower end of sheath pipe outer wall or afterbody are provided with afterbody injection capsule, and afterbody injection capsule passes through the Valve controlling that sheath pipe afterbody is supporting, and being connected between valve with afterbody injection capsule has conduit, and conduit is positioned at inside or the surface of sheath tube wall.
The front end of sheath pipe outer wall, after being positioned at head injection capsule, additionally it is possible to be provided with head injection capsule with the use of auxiliary injection capsule, auxiliary injection capsule is by the supporting Valve controlling of sheath pipe afterbody, being connected between valve with auxiliary injection capsule and have conduit, conduit is positioned at inside or the surface of sheath tube wall；Head injection capsule determines according to thickness or the operation requirement of bladder with the spacing of auxiliary injection capsule.
Inside or the tail end of described sheath pipe are additionally provided with sealing device.
Described sealing device is check valve or sealing ring.
The using method that the present invention is a kind of punctures sheath assembly is:
In lower urinary tract nature access procedures, it is inserted into lead sheath bar at sheath pipe, then the sheath pipe inserting lead sheath bar is inserted urethra, and also intravesical can be further inserted into, due to the non-acute angle of the head of lead sheath bar, urethra will not be formed strong stimulation；
Sheath pipe arrives intravesical, and the head top of sheath pipe is to bladder inwall, extracts lead sheath bar, inserts puncturing lever；
Puncturing lever pierces through wall of urinary bladder, and stretches out outside wall of urinary bladder by the head of sheath pipe, extracts puncturing lever, and head injection capsule is positioned at outside wall of urinary bladder, and bladder inwall is close to by auxiliary injection capsule, and afterbody injection capsule is positioned at urethra；
Inject capsule, afterbody injection capsule and auxiliary injection capsule to the head of sheath pipe and be injected separately into gas or liquid；Head injection capsule and auxiliary injection capsule compress outer wall and the inwall of bladder, the afterbody injection tight urethra of bag pressure respectively after filling；Head injection capsule, afterbody injection capsule and auxiliary injection capsule make sheath pipe fixing in the urethra of human body, from without sliding up and down, simultaneously work as airtight and hemostasis by compression effect.
The present invention is compared with prior art, have be skillfully constructed, feature easy to use, safe, by sheath pipe, puncturing lever and lead sheath bar with the use of, can be rapidly through the urethra of human body, and puncture wall of urinary bladder, and in head injection capsule, afterbody injection capsule and auxiliary injection capsule, injecting gas or liquid respectively, sheath pipe can be fixed in the urethra of human body, from without sliding up and down, simultaneously work as airtight and hemostasis by compression effect.Have and preferably use promotional value.
