Description

Technical Field

[0001] The present invention relates to the technical field of prostate treatment equipment, and in particular to a laser-based prostate enucleation and tissue pulverization integrated device. Background Art

[0002] Laser prostatectomy is a minimally invasive surgery that uses laser technology to precisely remove hyperplastic prostate tissue. The laser is transmitted through the urethra through an optical fiber that is inserted into the urethra to peel and remove the hyperplastic glands along the capsule layer. At the same time, the blood vessels are effectively sealed to achieve less or even no bleeding during the operation. This surgery has the advantages of less bleeding, faster recovery, and low recurrence rate, and is especially suitable for elderly and high-risk patients.

[0003] The patent with application number CN202221647271.2 discloses a dual-lens combined harvesting device for prostate enucleation, including an outer sheath and a working piece inserted therein, a gap is formed between the two, and the two are fixed and sealed; the working piece is provided with an optical fiber channel along its axial direction, a laser optical fiber is passed through its interior, one end of the laser optical fiber is suspended at the front end of the working piece, the working piece is provided with a pulverizer channel along its axial direction and located on one side of the optical fiber channel, a pulverizer is inserted in the pulverizer channel, and the working end of the pulverizer is suspended at the front end of the working piece. When the existing prostate enucleation tool is used to perform prostate enucleation, the enucleation and pulverization recovery work needs to be carried out step by step, which leads to the disadvantages of low surgical safety and low surgical efficiency. Due to different situations, clinical surgery sometimes requires the replacement of the electrosurgical device, especially for novice doctors, who have an imbalance in the mastery of electrosurgical and laser resection, so a single resection tool will bring many inconveniences.

[0004] In traditional tissue pulverizing devices, the suction force of the suction port is often too concentrated in a certain area due to the fixed position of the tissue suction port. When encountering large or viscous tissues, they are not easily sucked in and passed through the fixed suction port, and are accumulated near the suction port, forming a blockage. In addition, the axial position of the traditional suction port and the internal pulverizer is relatively fixed, resulting in a limited coverage range of the suction port. When dealing with irregularly shaped tissues, this limitation may require doctors to adjust the position or angle of the device multiple times to try to capture all target tissues, thereby increasing the complexity and time cost of the operation. Moreover, when faced with smaller hyperplastic tissues, although doctors tend to use electroresection to speed up, traditional devices require the laser resection device to be pulled out before replacing the electroresection device, which greatly reduces the flexibility of operation.

[0005] In view of this, we propose a laser-based prostatectomy and tissue pulverization device. Summary of the invention

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. After the driving motor of the laser-based prostate enucleation and tissue pulverization device is started, the intermediate gear will cause the outer rotating part and the inner rotating part to rotate in opposite directions. During this process, the position of the tissue suction groove is constantly changing, which not only effectively prevents tissue from being blocked near it, but also greatly improves the ease of use of the device, so that medical personnel no longer need to manually adjust its angle to find the cut tissue during use. At the same time, medical personnel can also convert the power connected to the laser resection system to the inside of the electrocution mechanism according to the specific situation of the patient's prostate, and then perform electrocution on the hyperplastic area of ​​the patient through the electrocution mechanism, further improving the flexibility of the overall equipment in actual use.

[0028] 2. The integrated prostate enucleation and tissue pulverization device based on laser technology has a tube wall convex groove on the outer wall of the telescopic tube. When the telescopic tube rotates, the lower convex rod extending into the tube wall convex groove cooperates to allow the telescopic tube to move back and forth while rotating, allowing the tissue suction groove to cover a wider area and more easily capture and suck prostate tissue in different positions, thereby effectively processing irregularly shaped tissues.

[0029] 3. The device is equipped with two resection systems, electroresection and laser resection, which can quickly adapt to various situations when used. Especially for novice doctors, they can choose one method to operate and switch to another resection method according to the actual clinical situation. Because electroresection has the advantages of less trauma, fast recovery and good surgical effect. However, electroresection will cause some bleeding during the operation, and for larger hyperplasia of the prostate gland, it may take a longer operation time and recovery period; while laser enucleation is a new surgical method formed later than electroresection, and more prostate will be removed. Therefore, the effect of the operation will be better than that of electroresection, and the control of the operation time will be more flexible, and the postoperative urinary control effect will be better. However, enucleation surgery requires a very familiarity with the internal anatomical structure of the prostate and a strong ability to identify the capsule, otherwise it is easy to get lost and cause complications such as perforation. Electroresection and laser enucleation each have their own advantages and disadvantages. The choice of surgical method should be determined based on the patient's specific situation and the doctor's professional opinion. In clinical surgery, the patient's actual clinical situation is often different from the preoperative evaluation, and the doctor's state is different for each surgery. Therefore, the device can adapt to these situations and can choose electroresection or laser enucleation. In combination with a tissue crushing device, it can better and more accurately treat the prostate, realizing the three-in-one function of the device. Of course, the present invention only protects the front-end device, excluding the back-end power supply and laser source, because the switching of the power supply and laser source is a very common existing technology, and it only needs to be adapted and connected to the structure of the present invention before surgery.

[0077] Finally, it should be noted that the drive motor 400 involved in the present invention is a universal standard part or a part known to technical personnel in this field. Its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods. In the idle space of this device, the drive motor 400 is connected to the external power supply through a wire. The specific connection method should refer to the working principle of the present invention. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection methods are all well-known technologies in the field.

[0078] When the laser-based prostate enucleation and tissue pulverization integrated device of the present invention is used, first, the insertion outer tube 110 in the outer pin 100 is inserted into the prostate of the patient, and the water inlet pipe 140 and the water outlet pipe 150 are respectively installed on the outer side wall of the outer sleeve 130;

[0080] Then, the medical staff inserts the laser optical fiber 340 into the probe rod 320, extends the end portion to the front end of the limiting circular plate 330, and performs laser enucleation on the hyperplastic part according to the specific situation of the prostate hyperplasia of the patient;

[0081] During the laser enucleation process, physiological saline is injected into the outer tube 130 through the water inlet pipe 140, and 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 patient's prostate through the water outlet hole 111 at the end of the outer tube 110. At the same time, negative pressure is formed in the water outlet pipe 150 through the external water pump, and the liquid in the prostate is sucked out from the gap between the inner transfer tube 231 and the connecting tube 222, thereby preventing the patient's prostate from being overfilled;

[0082] After the medical staff completes the cutting of the prostate hyperplasia tissue, they extract the remaining laser fiber 340 and start the drive motor 400, so that its output shaft drives the worm 214 in the fixing part 210 to rotate;

[0083] After the worm 214 rotates, it contacts the outer ring gear 224 and drives it to rotate together. At this time, the inner ring gear 225 on the inner wall of the outer rotating tube 221 contacts the intermediate gear 215 and drives it to rotate. Then, through the contact between the intermediate gear 215 and the docking ring gear 232, the inner rotating tube 231 is driven to rotate in the opposite direction to the outer rotating tube 221.

[0084] The connecting tube 222 rotates together with the outer rotating tube 221, driving the inner inserting tube 242 and the telescopic tube 241 to rotate. At this time, the contact position between the groove wall of the tube wall convex groove 2410 and the lower convex rod 213 is constantly changing, so that the telescopic tube 241 can move back and forth while rotating.

[0085] The cut prostate tissue is sucked into the tissue suction groove 2411 along the direction of the liquid flow. At this time, the high-speed rotating crushing teeth 235 cut the sucked part. After the crushed tissue moves to the position of the blocking ring 233, it is immediately discharged from the discharge groove 2220 and poured into the inside of the water outlet pipe 150.

[0086] After the prostate tissue is cleaned, the tissue pulverizing system 200 together with the laser ablation system 300 are first taken out from the outer pin 100, and then the outer pin 100 is taken out from the patient's prostate.
