Description
Technical field
The utility model is related to technical field of medical instruments, more particularly to a kind of prostate laser is cuted out except stripping device is pushed away, and is fitted
Cuted out for urinary system prostate laser except operation.
Background technology
Benign prostatic hyperplasis (Benign Prostatic Hyperplasia, abbreviation BPH) be in middle-aging male most
A kind of common Chronic Progressive urologic disease, it is made slow progress, but increases with the age of patient, it will influence patient
Quality of life, and serious complication may be caused, or even cause whole body system disease.Several investigation show that BPH suffers from
Sick rate in 60 years old elderly men more than 43%, more than 80 years old illness rate up to more than 80%, and the patient wherein more than 1/3 need into
Row operative treatment is to alleviate clinical symptoms.With extensive use of the per urethra Minimally Invasive Surgery in clinical position, current prostate
" goldstandard " that enucleation gradually instead of open surgery and be treated as BPH.Wherein, Bladder stone enucleation of the prostate (Holmium
Laser Enucleation of the Prostate, abbreviation HoLEP) due to its have it is safe and reliable, cut out except efficiency high and only
The features such as blood is good and as the major way in Enucleation of the prostate.
In order to better control over optical fiber in operation, someone designs and improves optical fiber control device, to adjust optical fiber
Retreat, so as to complete tissue cutting.However, in whole surgical procedure, in addition to the laser cutting of optical fiber, prostata tissue
Blunt separation equally play effect of crucial importance.If using existing optical fiber control device, then after retraction optical fiber,
Need to push away stripping to tissue progress using the sheath body of peephole, to complete the blunt separation of tissue, still, can so compare difficult control

When the optical-fibre channel 14 is axially retreated, the optical-fibre channel control structure 20 can be carried to the optical-fibre channel joystick 19
For an auxiliary force so that the optical-fibre channel 14 is retreated rapidly.
It is shown in Figure 2, it is in the present embodiment, described to cut out except first 17 include a horizontal part 172 and a rake 171, institute
State shape between horizontal part 172 and the rake 171 to have angle, the scope of the angle is 30 degree~60 degree, and described cut out
Except first 17 be in spade, then, the impetus of junction is acted between enhancing horizontal part 172 and rake 171, so as to effective
Ground carries out blunt separation to prostata tissue, pushes away stripping and the action such as prizes.In the present embodiment, the horizontal part 172 and described
Rake 171 is hollow, and is made up of metallic rod.In other parts embodiment of the present utility model, the horizontal part 172
It is solid with the rake 171, helps to strengthen the impetus effect of junction between horizontal part 172 and rake 171.
It is in the present embodiment, described to cut out except bar 15 includes the first bar portion (not shown) and the second bar portion (not shown),
Same one end of first bar portion and second bar portion is be arranged in parallel, and the optical-fibre channel 14 is worn between described same one end
Cross and can freely retreat.That is, the optical-fibre channel 14 is cuted out except bar 15 is in same level with described.
With continued reference to shown in Fig. 1, in the present embodiment, one is set to cut out except bar on the extension 18 of the camera lens sheath body 11
Joystick 21, it is described cut out except bar joystick 21 with it is described cut out inside except bar epitheca 13 cut out except bar 15 is connected, for making
State and cut out except bar 15 is axially moved forward and backward, so as to control the action cuted out except first 17.
It is described to cut out except bar joystick 21 and the optical-fibre channel joystick 19 are separately positioned on the camera lens sheath body 11
Extension 18 top and bottom, be spaced apart, and be independent of each other.And, cut out respectively except bar joystick 21 and institute described
Optical-fibre channel joystick 19 is stated to be controlled, so as to cut out except bar 15 and optical-fibre channel 14 are moved independently of one another, so that
Cut out except first 17 and optical fiber 16 realize its each function., can when operating the optical-fibre channel joystick 19 in surgical procedure
To control the advance and retreat of the optical-fibre channel 14, so that 16 pairs of tissues of the optical fiber are cut by laser, when operation is cuted out except bar control
During handle 21 processed, it can control to state and cut out except the advance and retreat of bar 15.It is described to cut out except first 17 are located at visual field center, it is described to cut out except first 17 pairs of wing
Prostata tissue in Guang carries out passivity and divested, and due to using blunt separation mode, is cuted out therefore, it is possible to greatly increase except process
In speed and safety.Furthermore, it is described to cut out the rake 171 except first 17 to tilt down, so that described cut out except first 17 will not hide
Keep off surgical field of view, and when operation is described cut out make except bar joystick 21 described in cut out retreated except bar 15 when, now, described cut out is removed
First 17 cut out except bar epitheca 13 can clamp a little tissue jointly with described, urethra are taken out of, in order to successor operation.
With continued reference to shown in Fig. 1, in the present embodiment, cuted out described on the outer surface except bar epitheca 13 and close to described
Cutting out to remove sets one to fix support 22 at first 17, the fixed support 22 is welded in the camera lens sheath body 11, and the fixed support 22 is used for branch
Cuted out described in support except bar epitheca 13.
Therefore, the utility model cutting out except both first 17 and optical fiber 16 are combined by spade, and independently running, so that
It can complete to carry out blunt separation and laser cutting to prostata tissue, so that operation is more successfully carried out.
It is noted that the prostate laser is cuted out except the conventional knot for pushing away the undisclosed part of other in stripping device for this area
Structure, will not be repeated here.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
Art personnel, on the premise of the utility model principle is not departed from, can also make some improvements and modifications, these improvements and modifications
Also it should be regarded as protection domain of the present utility model.
