Puncture needle insertion support cover is interior and the through hole of support cover can be passed through the biopsy channel.
Further, the support cover include cover body, enclosing cover and inner cap, the enclosing cover be arranged on the cover body rear end and
Be threadedly coupled with cover body, the inner cap be co-axially located at it is outer cover and can be around own axis, the multi-directional ball is arranged on interior
The edge of lid.
Further, multiple depressions are circumferentially evenly equipped with the periphery of inner cap, covers be provided through enclosing cover outside
The stop pin that outer peripheral face and front end can be extend into the depression.
The beneficial effects of the utility model：A kind of aspiration biopsy of prostatic gland utensil of the present utility model, including puncture needle, also
Intrarectal support cover is can be inserted into including front end, the front end side wall of the support cover is provided with a biopsy channel, the support cover
Rear end be provided with the multi-directional ball inside and outside point row support cover of a both sides, the multi-directional ball be provided with puncture needle is inserted in support cover,
And the through hole of support cover can be passed through the biopsy channel.The aspiration biopsy of prostatic gland utensil of the structure, makes puncture needle per rectum
Into prostate, the wound caused to patient tissue is small.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A portions enlarged diagram in Fig. 1；
Fig. 3 is the operating diagram of aspiration biopsy of prostatic gland utensil of the present utility model.
Embodiment
To be easy to understand technological means, creation characteristic, reached purpose and effect of the utility model realization, below
With reference to embodiment, the utility model is expanded on further.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：A kind of aspiration biopsy of prostatic gland utensil, including wear
Pricker 30, puncture needle 30 includes needle guard and the biopsy needle being sheathed in needle guard, in addition to the support that front end can be inserted into rectum 10
Cover 40, support cover 40 is a closed hollow-core construction, integrally into cylinder, and its effect is to be blocked in the excreta in rectum 10
Outside support cover 40, the environment of a relative clean, the forward end camber of support cover 40, side are provided for the use of puncture needle 30
Just rectum 10 is inserted, the front end side wall of the support cover 40 is provided with a biopsy channel 411, the biopsy channel 411 is hole or groove,
A cover plate slided can be set to close biopsy channel 411 in support cover 40, the rear end of the support cover 40 is provided with one
Being provided with multi-directional ball 50 inside and outside the row support cover 40 of both sides point, the multi-directional ball 50 makes puncture needle 30 insert in support cover 40, simultaneously
The through hole 51 of support cover 40 can be passed through the biopsy channel 411.Support cover 40 is inserted before rectum 10, rotational support cover 40,
Make biopsy channel 411 towards the side of prostate 20, then insert support cover 40 in rectum 10, until the front end of support cover 40 is supported
Up near prostate 20, then puncture needle 30 is worn through the biopsy channel 411 on the through hole 51 and support cover 40 in multi-directional ball 50
The needle guard of pricker 30 passes through after the wall of rectum 10 and to release the biopsy needle in needle guard, and is pierced into prostate 20 and is carried with completing tissue
Take.The puncture direction of puncture needle 30 can be adjusted by multi-directional ball 50, and the scope of biopsy channel 411 can guarantee that puncture needle 30 exists
Activity in suitable scope.In whole puncture process, biopsy needle does not contact the excreta in rectum 10, it is ensured that biopsy needle it is dry
In cleanliness, and puncture process, only need guiding through the wall of rectum 10 and reach at prostate 20, therefore the wound caused to patient tissue
It is small.
As the further improvement of such scheme, the support cover 40 includes cover body 41, enclosing cover 42 and inner cap 43, described outer
Lid 42 is arranged on the rear end of cover body 41 and is threadedly coupled with cover body 41, and the inner cap 43 is co-axially located on enclosing cover 42 and can
Around own axis, the multi-directional ball 50 is arranged on the edge of inner cap 43, and inner cap 43 is installed along with cover body with enclosing cover 42
41 rear ends, when cover body 41 is inserted in rectum 10, first can not cover enclosing cover 42, can be first to work after the position determination for waiting cover body 41
Enclosing cover 42 is covered again after the inwall of rectum 10 sterilization at inspection passage 411 carries out follow-up puncture procedure.Because biopsy channel 411 is located at
The front end side wall of cover body 41, therefore inner cap 43 is rotated when puncturing, it is located at the multi-directional ball 50 installed in the edge of inner cap 43
The homonymy of biopsy channel 411 or the opposite side positioned at biopsy channel 411, so when puncturing, puncture needle 30 can be obtained more
The adjustment space of wide-angle, is that the smooth tissue of prostate 20 that extracts provides safeguard.
As the further improvement of such scheme, multiple depressions 431 are circumferentially evenly equipped with the periphery of inner cap 43,
The stop pin 44 that the outer peripheral face of enclosing cover 42 and front end can be extend into the depression 431 is provided through on enclosing cover 42, so as to lock
Pin 44 coordinates to form the spin locking to inner cap 43 with depression 431, it is ensured that this will not be rotated in puncture process.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above, for
For those skilled in the art, it is clear that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and without departing substantially from this
