Several studies have shown that BPH prevalence is greater than 43% in older men aged 60 years and greater than 80% in older 80 years, while more than 1/3 of the patients require surgical treatment to alleviate clinical symptoms. With the widespread use of transurethral minimally invasive surgery in clinical work, the current enucleation of the prostate gradually replaces open surgery as a "gold standard" for BPH treatment. Among them, holmium laser enucleation (Holmium Laser Enucleation of the Prostate, hoLEP for short) is a main mode in enucleation of prostate due to its characteristics of safety and reliability, high enucleation efficiency, good hemostasis, etc.
In order to better control the optical fiber during surgery, fiber control devices have been designed and improved to adjust the advancement and retraction of the optical fiber to accomplish tissue dissection. However, passive separation of prostate tissue plays an extremely important role in addition to laser ablation of the optical fiber throughout the procedure. If the existing optical fiber control device is adopted, after the optical fiber is retracted, the sheath body of the observation mirror is required to push and peel the tissue so as to complete the blunt separation of the tissue, however, the depth of the blunt separation is difficult to control, the intensity of the blunt separation is difficult to master, the difficulty of operation is increased, and especially the learning curve of a beginner is increased.

Referring to fig. 1 and 2, the present invention provides a laser enucleation push-dissection device for prostate tissue inside a bladder, the device comprising: a lens sheath 11, in which an observation mirror 12 is arranged inside the lens sheath 11; an enucleation rod outer sheath 13, wherein the enucleation rod outer sheath 13 is arranged at the bottom of the lens sheath body 11 and is connected with the lens sheath body 11, an enucleation rod 15 and an optical fiber channel 14 are arranged in the enucleation rod outer sheath 13, the enucleation rod 15 is arranged at the bottom of the optical fiber channel 14, and an optical fiber 16 is arranged in the optical fiber channel 14, wherein the optical fiber 16 can be replaced; the optical fiber 16 is used for performing laser cutting on tissues; an enucleation head 17 is arranged at one end of the enucleation rod 15, the enucleation head 17 protrudes out of the enucleation rod 15 outer sheath 13, and the enucleation head 17 is in a shovel shape and is used for performing blunt separation on tissues. Note that the tissue described herein refers to prostate tissue.
In this embodiment, the length of the lens sheath 11 is 280-320 mm, preferably 300mm. The lens sheath 11 has a diameter of 20 to 22Fr, preferably 22Fr, so that pain and irritation to a patient can be reduced. The diameter of the lens sheath 11 is slightly larger than the diameter of the built-in observation mirror 12. Further, a scope 12 is disposed inside the lens sheath 11, wherein the scope 12 is a cystoscope. A lens (not shown) is arranged at one end of the observation mirror, and the lens is aligned with the prostate tissue in the bladder and is used for observing the condition in the bladder; an eyepiece (not shown) is provided at the other end of the scope 12, the eyepiece being provided in a lens inlet 22, the lens inlet 22 being provided at the end of the extension 18 of the lens sheath 11. The operator views the target (i.e., the prostate tissue) through the eyepiece at the position of the entrance port 22. Since the scope 12 employs a lens similar to a cystoscope, the field of view of the scope 12 can be enlarged, facilitating viewing during surgery.
With continued reference to fig. 1, an optical fiber 16 is disposed within the fiber channel 14, the optical fiber 16 being used to laser cut prostate tissue. In this embodiment, an outlet end (not shown) with a narrowed inner wall is disposed at one end of the fiber channel 14, and the diameter of the outlet end is set so that the optical fiber 16 just passes through the outlet end, so that the optical fiber 16 can be ensured to be stable in the fiber channel 14 and not to move randomly. And the optical fiber 16 protrudes from the outlet end.
In this embodiment, a fiber channel control handle 19 is disposed at an end of the extension 18 of the lens sheath 11 opposite to the enucleation head 17, and the fiber channel control handle 19 is used to control the fiber channel 14 to move axially back and forth. Further, the fiber channel 14 is controlled to move back and forth by the operation of the fiber channel control handle 19, and then the fiber channel 14 drives the optical fiber 16 to move back and forth. Herein, "forward movement" (or advancement) refers to movement toward the prostatic tissue within the bladder, and "backward movement" (or retraction) refers to movement away from the prostatic tissue within the bladder.
An optical fiber channel control structure 20 is disposed at an end of the extension portion 18 of the lens sheath 11 opposite to the enucleation head 17, the optical fiber channel control structure 20 is respectively connected with the optical fiber channel 14 and the optical fiber channel control handle 19, and the optical fiber channel control structure 20 is a hinge device.

In the present embodiment, the horizontal portion 172 and the inclined portion 171 are hollow and made of a metal rod. In other embodiments of the invention, both the horizontal portion 172 and the sloped portion 171 are solid, which helps to enhance the point of application at the junction between the horizontal portion 172 and the sloped portion 171.
In this embodiment, the enucleation rod 15 includes a first rod portion (not shown) and a second rod portion (not shown), the same ends of the first rod portion and the second rod portion are disposed in parallel, and the fiber channel 14 passes between the same ends and can freely advance and retreat. That is, the fibre channel 14 is at the same level as the enucleation stem 15.
With continued reference to fig. 1, in this embodiment, an enucleation rod control handle 21 is disposed on the extension 18 of the lens sheath 11, where the enucleation rod control handle 21 is connected to the enucleation rod 15 inside the enucleation rod outer sheath 13, and is used to move the enucleation rod 15 axially back and forth, so as to control the enucleation head 17.
The enucleation rod control handle 21 and the fiber channel control handle 19 are respectively disposed at the top and bottom of the extension 18 of the lens sheath 11, are spaced apart from each other, and do not affect each other. And, the enucleation rod control handle 21 and the fiber channel control handle 19 are controlled to move the enucleation rod 15 and the fiber channel 14 independently, respectively, so that the enucleation head 17 and the fiber 16 perform their respective functions. During operation, the optical fiber channel control handle 19 is operated to control the advance and retreat of the optical fiber channel 14, so that the optical fiber 16 performs laser cutting on tissue, and the enucleation rod 15 is operated to control the advance and retreat of the enucleation rod 21. The enucleation head 17 is positioned in the center of the visual field, and the enucleation head 17 carries out blunt stripping on the prostate tissue in the bladder, and the speed and safety in the enucleation process can be greatly increased due to the blunt separation mode. Furthermore, the inclined portion 171 of the enucleation head 17 is inclined downward so that the enucleation head 17 does not obstruct the surgical field, and when the enucleation rod 15 is retracted by operating the enucleation rod control handle 21, at this time, the enucleation head 17 and the enucleation rod outer sheath 13 can clamp a little tissue together and take out the urethra for the subsequent operation.
With continued reference to fig. 1, in this embodiment, a fixing support 22 is disposed on the outer peripheral surface of the enucleation rod sheath 13 and near the enucleation head 17, the fixing support 22 is welded to the lens sheath body 11, and the fixing support 22 is used for supporting the enucleation rod sheath 13.
