Description

Prostate enucleation and tissue smashing integrated device based on laser technology
Technical Field
The invention relates to the technical field of prostate treatment equipment, in particular to a laser technology-based integrated device for enucleation of prostate and tissue disruption.
Background
The laser enucleation is a minimally invasive operation for precisely cutting the tissue of the hyperplasia prostate by utilizing a laser technology, laser is conducted through insertion of optical fibers into the urethra, the hyperplasia glands are peeled off and enucleated along the coating layer, meanwhile, the blood vessels are effectively sealed, little bleeding or even no bleeding is realized in the operation, and the operation has the advantages of little bleeding, quick recovery, low recurrence rate and the like, and is particularly suitable for elderly and high-risk patients.
The patent with the application number of CN202221647271.2 discloses a double-lens combine harvester for the enucleation of the prostate, which comprises an outer sheath and a working piece inserted in the outer sheath, wherein a gap is formed between the outer sheath and the working piece, the outer sheath and the working piece are fixedly and hermetically connected, an optical fiber channel is formed in the working piece along the axial direction of the working piece, a laser optical fiber is penetrated in the working piece, one end of the laser optical fiber is suspended at the front end of the working piece, a pulverizer channel is formed in the working piece along the axial direction of the working piece and is positioned at one side of the optical fiber channel, a pulverizer is inserted in the pulverizer channel, the working end of the pulverizer is suspended at the front end of the working piece, and when the enucleation of the prostate is implemented by using the existing enucleation tool of the prostate, enucleation and the pulverizing recovery work needs to be carried out step by step, so that the defects of low operation safety and low operation efficiency are caused. Because of different situations, the electric cutting device is sometimes replaced in clinical operation, and especially for a novice doctor, the electric cutting and the laser cutting mode are unbalanced, and a single cutting tool brings a plurality of inconveniences.
In the conventional tissue morcellating device, the suction force of the suction port is often too concentrated in a certain area due to the fixation of the position of the tissue suction port, and when large or sticky tissues are encountered, they are not easily sucked smoothly and pass through the fixed suction port, so that the tissues are accumulated near the suction port to form a blockage. In addition, the axial position of the conventional suction port and the internal morcellator are relatively fixed, resulting in limited coverage of the suction port, which may require multiple adjustments of the device position or angle to attempt to capture all target tissue while treating irregularly shaped tissue, thereby increasing the complexity and time costs of the procedure, and, while facing less proliferating tissue, the physician tends to employ electro-ablation for speed, but conventional devices require the laser ablation device to be withdrawn prior to the electro-ablation device replacement, which significantly compromises operational flexibility.
In view of this, we propose an integrated device for enucleation of prostate and tissue disruption based on laser technology.

Finally, it should be noted that, the driving motor 400 according to the present invention is a general standard component or a component known to those skilled in the art, the structure and principle thereof are all known by those skilled in the art or known by conventional experimental methods, at the idle position of the device, the driving motor 400 is connected to an external power source through a wire, the specific connection means should refer to the working principle in the present invention, and the electrical connection between the electrical devices is completed according to the sequential working order, and the detailed connection means are all known in the art.
When the integrated device for enucleating and smashing the prostate based on the laser technology is used, firstly, the outer tube 110 inserted into the outer pin 100 is extended into the prostate of a patient, and the water inlet tube 140 and the water outlet tube 150 are respectively arranged on the outer side wall of the outer tube 130;
Next, the probe 320 of the laser ablation system 300 is inserted into the inner tube 231 of the inner rotating part 230, the limit circular plate 330 is fixed at the end position of the probe 320, and the front end of the fixing part 210 of the tissue pulverizing system 200 is extended into the inner tube 120;
Then, after the medical staff inserts the laser fiber 340 into the probe 320 and extends the end to the front end of the limit circular plate 330, the laser enucleation is carried out on the proliferated part according to the specific condition of the prostate hyperplasia part of the patient;
During the laser enucleation play, normal saline is injected into the outer sleeve 130 through the water inlet pipe 140, then flows into the gap between the outer tube 110 and the inner tube 120 through the water outlet groove 131, and is injected into the prostate of a patient through the water outlet hole 111 at the end part of the outer tube 110, and at the same time, negative pressure is formed in the water outlet pipe 150 through the external water pump, so that the liquid in the prostate is sucked out from the gap between the inner tube 231 and the connecting tube 222, and the overfilling of the prostate of the patient is avoided;
After the medical staff completes the cutting work of the tissue with the hyperplasia of the prostate, the rest laser fiber 340 is extracted, and the driving motor 400 is started, so that the output shaft of the driving motor drives the worm 214 in the fixing part 210 to rotate;
The worm 214 rotates to contact with the outer ring gear 224 and drive the outer ring gear 224 to rotate together, at this time, after the inner ring gear 225 on the inner side wall of the outer rotating pipe 221 contacts with the intermediate gear 215, the inner ring gear 225 is driven to rotate, and then the intermediate gear 215 contacts with the abutting ring gear 232, so that the inner rotating pipe 231 is driven to rotate in the opposite direction to the outer rotating pipe 221;
The connecting pipe 222 rotates along with the outer rotating pipe 221 and drives the inner cannula 242 and the telescopic pipe 241 to rotate, at this time, the contact position of the groove wall of the pipe wall convex groove 2410 and the lower convex rod 213 is continuously changed, so that the telescopic pipe 241 rotates and simultaneously moves back and forth in a reciprocating manner;
The cut prostate tissue is sucked into the tissue suction groove 2411 along with the flowing direction of the liquid, at this time, the sucked part of the tissue is cut by the crushing teeth 235 rotating at high speed, and the crushed tissue is discharged from the discharge groove 2220 and is poured into the water outlet pipe 150 after moving to the position of the material blocking ring 233;
After the prostate tissue is cleaned, the tissue morcellating system 200, along with the laser ablation system 300, is removed from the outer pin 100, and the outer pin 100 is removed from the patient's prostate.
