Description
Technical field
Before prostate dilation operation medical instruments field, more particularly to a kind of visualization positioning of bulbous urethra
Row gland dilator.
Background technology
Hyperplasia of prostate is the common disease of middle-aging male, so-called hyperplasia of prostate, mainly due to prostata tissue
Hyperplasia, cause its volume increase, and then extrude around organ, cause urinary tract to diminish and narrow, thus occur dysuria, urine
Frequently, the symptom such as urination time length.Traditional therapeutic modality is that prostata tissue is cut, but perform the operation to patient strike compared with
Greatly, and old human body and ability to bear at heart to operation are poor, it is unwilling to undergo surgery.Treatment side more advanced at present
Formula is that prostate expands operation, and this treatment operation is by the way that prostate dilator is inserted into patient's prostatic urethra, profit
The mode filled with sacculus water filling is treated, and this operation wound is small, and operating time is short, and safety coefficient is high, is that prostate is suffered from
The optimal selection of person.
But mesh prostate dilator generally existing positioning it is inaccurate the problem of, in surgical procedure, medical personnel with
Borrower's pipe intuition and experience are touched convex in prostate tip or touched by finger pressure perineum by rectal touch to be positioned
It is convex to split the position that pipe is promoted in vivo to judge to expand.But it is due to the build difference of patient, for obese patient, Yi Sheng
The position of convex can not be preferably sensed in operation, so as to cause catheter positioning inaccurate so that the prostate of part hyperplasia
Do not expanded so that the effect performed the operation declines, it is also possible to trigger because non-prostatic urethra is excessively expanded urine control damage with
Urethral injury.
The content of the invention
Expand it is an object of the invention to provide a kind of prostate of bulbous urethra visualization positioning and split pipe, by main pipe
The soft lens that side is stretched out observes the position of convex, exists to be accurately positioned main pipe position, and then overcome in background technology
Positioning it is inaccurate the problem of.
To realize above-mentioned technical purpose, the present invention proposes a kind of prostate expansion of bulbous urethra visualization positioning and splits pipe,
Including main pipe and soft lens, catheter, flush pipe, capsula interna pipe and external capsule pipe are provided with the main pipe, before the main pipe
End is respectively equipped with the opening being connected with catheter and flush pipe, and external capsule and capsula interna are provided with open rear section described in front end, described interior
Capsule is located at outer intracapsular.Convex, the main pipe at the convex rear are arranged at intervals with the main pipe at the external capsule tail rear portion
Side is provided with opening, and the soft lens stretches out from the outlet.
It is preferred that, it is fusiform or ellipticity after the capsula interna expansion, is cylindric after the external capsule expansion.
It is preferred that, the length of the capsula interna is less than or equal to the 3/4 of external capsule length.
It is preferred that, a diameter of 5~8mm of the main pipe, it is 300~500mm to dominate length of tube.
It is preferred that, the overall diameter under unused state of the capsula interna and external capsule is not more than 9mm.
It is preferred that, the use pressure of the capsula interna and external capsule is 0.25~0.45Mpa.
It is preferred that, the catheter, flush pipe, it is respectively equipped with a connection piece on the tail end of capsula interna pipe and external capsule pipe, it is described
Screw thread is provided with connector, and the connector is provided with a seal cap.
It is preferred that, the soft lens includes soft shell, mirror body and camera lens, and the camera lens is arranged on the mirror body front end, institute
Mirror body is stated in the soft shell.
Compared with prior art, the beneficial effects of the invention are as follows：Pass through the soft lens stretched out at the opening of main pipe side
To observe the position of convex, it can realize that visualization is accurately positioned, greatly reduce the difficulty of operation technique, while also carrying
High surgical effect.
