Abstract
The utility model provides a prostate dilator positioning in cysts, which can treat urethrophraxis which is caused by the prostate hyperplasia and reserve the prostate. The utility model is characterized in that a bending probe (1), a positioning part (2), an expanding component (3), a connecting sleeve (14) and a center rod sleeve (4) are continuous, smooth and easy to be inserted into the cyst through a urethra, and the front section is provided with the positioning part (2) which automatically positions accurately by the right rotation of a regulating handle (5). The expanding component (3) is spread by the farther right rotation of the regulating handle (5), thus achieving the purpose of expanding and increasing corpulent prostate, and getting rid of the urethrophraxis. The utility model is applied to the clinic without special devices, has convenient operation, can not damage external urethral sphincter and has strong safety and low treating expenses.
Description
This utility model belongs to technical field of surgical instrument.It is applicable to and keeps prostate with urethral obstruction due to the releasing hyperplasia of prostate.
Existing air bag prostate dilator is a kind ofly not possess the reservation prostate of inserting positioner to remove the operating theater instruments of urethral obstruction due to the prostatic hyperplasia.
The purpose of this utility model is to provide a kind of can accurately locate voluntarily, avoid damaging the operating theater instruments product of urethral obstruction due to the treatment prostatic hyperplasia of the urethra and the musculus sphincter of external urethra.
This utility model is achieved in that and utilizes the stainless steel metal material parts to realize the plane multi-bar linkage system that is made of bendable probe (1), positioning element (2), extension part spare (3), joint sleeve (14), center-pole (15), center-pole sleeve pipe (4), fixed sleeving (17), regulating handle (5), drive link (6) by connection.The front end of bendable probe (1) is slick and sly parabola; Bendable probe (1), positioning element (2), extension part spare (3), joint sleeve (14) and center-pole sleeve pipe (4) are that 0.7 centimetre, length are 30 centimetres cylindrical outer shape for continuous, smooth, diameter.The displacement of center-pole (15) determined positioning element (2) to be in positioning states and two to expand (10) the open width of starting, and therefore, is marked with location scale and the expansion that center-pole (15) displacement realizes at drive link (6) and opens the width scale.
Below in conjunction with accompanying drawing this utility model is made description:
Fig. 1 is this utility model sketch map.
Fig. 2 is that positioning element launches sketch map.
Fig. 3 is that extension part spare launches sketch map.
With reference to Fig. 1, Fig. 2, Fig. 3, bendable probe (1) is riveted by bearing pin with positioning element (2).Positioning element (2), extension part spare (3) by front strut (7), locating rod (8), centre of location bar (16), preceding support chip (9), expand start (10), connecting plate (11), back support chip (12), rear pole (13), joint sleeve (14), center-pole (15) constitutes the plane multi-bar linkage, the bearing pin riveted joint is adopted in the connection that constitutes the part of hinges.Joint sleeve (14) adopts with center-pole sleeve pipe (4) and is threaded.Center-pole sleeve pipe (4) is fixedlyed connected with fixed sleeving (17).Center-pole (15) is fixedlyed connected with drive link (6).Fixed sleeving (17) is the rotatable flexible connection of tongue and groove with regulating handle (5).Regulating handle (5) adopts the screw thread scalable to be connected with drive link (6).
The intravesical location prostate enlarging device that this utility model provides, during use, this apparatus at first is in closure state (as Fig. 1) per urethra makes bendable probe (1), positioning element (2) insert intravesical.When pulling back center-pole (15) to the moment of torsion that right rotation regulating handle (5) is produced by the screw thread on the drive link (6) with hands, and direct pull centre of location bar (16) moves backward, and connecting plate this moment (11) does not have and moves.Because centre of location bar (16) moves backward, make angle of preceding support chip (7) and locating rod (8) rotation, form positioning states (as Fig. 2), outwards spur this apparatus, make locating rod (7) be fixed in internal urethral orifice.Continue this moment to right rotation regulating handle (5), pulling center-pole (15) moves backward, the end of centre of location bar (16) promotes connecting plate (11) and moves backward, make preceding support chip (9), back support chip (12) and angle of rear pole (13) rotation, before the rotation of support chip (9) and back support chip (12) make two to expand start (10) parallel in the opposite direction mobile, reach enlarged state (as Fig. 3).This expansion is started the prostate that makes the hypertrophy hypertrophy and is opened by expansion and tear, and prostate connective tissue and smooth muscle tissue are elongated, and surpass and have reduced the elastical retraction power of capsula prostatica, thereby blocking of prostate section urethra is disengaged.Otherwise to anticlockwise regulating handle (5), positioning element (2), extension part spare (3) recover closure state, and this apparatus can be extracted by urethra smoothly.Hyperplasia of prostate often causes urethral obstruction, and Drug therapy can not solve root problem, often needs open operation excision or Transurethral prostatic electroresection A.But how sick old, weak because of the patient,, surgical risk is very big or can not tolerate surgery.Prostate has immunologic function, and keeping prostate and remove urethral obstruction should be reasonable treatment.Though the clinical balloon dilation that adopts need not operated at present, insert telltale mark but lack, need urethrography under TV, to adjust balloon positions or per rectum touch location, because of needing special installation and complicated positioning action, and the situation of musculus sphincter of external urethra damage causing urinary incontinence still comparatively more sees, thereby has limited its promotion and application.This utility model is used for the treatment that hyperplasia of prostate causes urethral obstruction, need not operate on, can accurately locate voluntarily, not need special installation, simple to operate, high safety, medical expense low, be easy to promote, therefore have great practical value and social meaning.
Claims (2)
1, a kind of intravesical location prostate enlarging device, it is characterized in that bendable probe (1) and positioning element (2) rivet by bearing pin, positioning element (2), extension part spare (3) is by front strut (7), locating rod (8), centre of location bar (16), preceding support chip (9), expand start (10), connecting plate (11), back support chip (12), rear pole (13), joint sleeve (14), center-pole (15) constitutes plane many bars hinges mechanism by the bearing pin riveted joint, joint sleeve (14) adopts with center-pole sleeve pipe (4) and is threaded, center-pole sleeve pipe (4) is fixedlyed connected with fixed sleeving (17), center-pole (15) is fixedlyed connected with drive link (6), fixed sleeving (17) is the rotatable flexible connection of tongue and groove with regulating handle (5), and regulating handle (5) adopts the screw thread scalable to be connected with drive link (6).
