Description

Technical Field

[0001] The invention belongs to surgical instruments for prostate hyperplasia, and in particular relates to a continuously accessible prostate anchor delivery system. Background Art

[0002] Benign prostatic hyperplasia (BPH) is a common disease in middle-aged and elderly men. Its main manifestations include hyperplasia of prostate stroma and glandular components, benign prostatic enlargement (BPE), lower urinary tract symptoms (LUTS), and bladder outlet obstruction (BOO). Currently, there are two treatment methods for BPH: drug therapy and surgical treatment. Surgical treatment includes: (1) transurethral resection of the prostate; (2) suprapubic or retropubic prostatectomy; (3) laser prostatectomy or resection; (4) minimally invasive treatment with implants. Among them, minimally invasive treatment with implants is to implant a permanent implant into the prostate through a delivery system, and use the implant to mechanically separate the two lobes of the prostate so that it no longer blocks the urethra, thereby continuously relieving the symptoms of BPH patients. There is no need to resect or ablate the prostate tissue, which can relieve the pain of patients and enable them to return to normal life as soon as possible.

The prostate 04 is located outside the urethra at the junction of the urethra 03 and the bladder 01. The health of the prostate 04 has an important impact on the normal function of the male reproductive system. For example, if the prostate hyperplasia occurs, it will squeeze the urethra 03 and narrow the urethral passage, which may cause problems such as frequent urination, urgent urination, painful urination, and sexual dysfunction.

The anchor implant 26 includes a plurality of groups of anchor monomers connected in sequence, and the anchor monomers include an anchor line 2601 and a distal anchor 2602 and a proximal anchor 2603 disposed at both ends of the anchor line. A break point 2604 is disposed on the anchor line between two adjacent groups of anchor monomers, and a knife edge is disposed at a specific position in the front end cavity of the delivery pipe 2. When the anchor monomer of the anchor implant 26 is subjected to a predetermined force, it can be disconnected. When the proximal anchor 2603 of the anchor monomer is implanted on the urethral side, the break point 2604 of the anchor implant 26 can be conveniently disconnected by pushing the delivery pipe 2 toward the front end.

After the wire slider 131 moves forward with the driving slide 13 to the front end of the limit tongue block 134, the clamping edge 136 provided at the lower side of the limit tongue block 134 can be correspondingly clamped to the upper end of the wire slider 131, and the clamping edge 136 can limit the wire slider 131 from resetting backward with the driving slide 13, that is, when the driving disc 22 drives the driving slide 13 to move forward along the mounting base 12 during a driving process, the driving slide 13 can be correspondingly brought The moving line slider 131 moves forward to the front end of the limiting tongue block 134, and the limiting tongue block 134 can clamp the line slider 131 to the column, and this thread is used to drive the puncture needle 11 to pierce out; when entering the next driving process, the trigger is pulled to drive the driving disk to rotate a thread, and the driving disk drives the driving slide plate 13 to slide toward the rear end along the mounting base plate 12, and drives the puncture needle to partially retract along the conveying pipe 2. Since the line slider 131 is stuck by the limiting tongue block 134, the driving slide plate 13 can stretch the coil spring 16 to store force during the retreat process. This driving process is the partial contraction of the puncture needle 11, and the coil spring 16 is stretched to store force. A driving column 135 is arranged on the side of the limiting tongue block 134 close to the driving disk 22, and a driving protrusion 2208 is arranged in the circumferential direction of the driving disk 22. When the puncture needle 11 is partially retracted, that is, entering the next driving process, the trigger 7 is pulled to drive the driving disk 22 to rotate accordingly, and the driving protrusion 2208 lifts the driving column 135 upward as the driving disk 22 rotates. The driving column 135 can drive the limiting tongue block 134 to move upward to release the position restriction of the wire slider 131. The wire slider 131 returns to its original position backward along the mounting base plate 12 under the drive of the coil spring 16, realizes the tightening of the anchor line 2601, and drives the driving slide plate 13 to return completely backward along the mounting base plate 12. At this time, the puncture needle 11 finally returns completely and completes the release of the proximal anchor 2603. The wire push block 24 and the clamping block 25 are integrally housed in the wire slider 131. As the driving slide 13 moves forward, the wire slider 131 drives the wire push block 24 to move forward and squeezes the annular protrusion 2502 to deform inward, causing the diameter of the clamping hole 2503 to shrink and grasp the anchoring implant 26. The wire slider 131 cooperates with the wire driving mechanism 8 to enable the anchoring implant 26 to move forward a certain distance along the inner cavity of the puncture needle 11.

[0029] like Figure 1 and Fig.15In the illustrated embodiment, the wire driving mechanism 8 comprises a wire connecting tube 84 sleeved outside the anchoring implant 26, and two marking areas 85 are arranged on the outer periphery of the wire connecting tube 84 with a spacing of one anchoring piece monomer length; a wire clamping block 83 is arranged on the outer periphery of one end of the wire connecting tube 84, and a button 81 is connected to the outer end of the wire clamping block 83, and a support spring 82 is sleeved on the rod body of the button 81, and the support spring 82 is supported on the side buckle cover 6. Under the action of the support spring 82, the button 81 drives the wire clamping block 83 inward to clamp the wire connecting tube 84, and an indication frame 9 corresponding to the marking area 85 is arranged on the side buckle cover 6. Under normal conditions, the button and wire clamp block of the wire driving mechanism 8 are pressed tightly against the outer periphery of the wire connecting tube, and the wire connecting tube cannot be moved; when the anchor unit needs to be moved forward, the button 81 is pulled outward to squeeze the support spring 82 and make the wire clamp block 83 disengage from the wire connecting tube 84, and the wire connecting tube 84 is driven to move forward by a position of the length of the anchor unit, and then the button is released. The button is reset under the action of the support spring to achieve locking of the position of the wire connecting tube.

[0030] The working principle or working method of the anchor delivery system of the present invention is as follows: The anchoring implant 26 of the present invention is composed of an anchoring line 2601 and a distal anchor 2602 and a proximal anchor 2603 distributed at a predetermined distance on the suture line. The anchoring implant 26 is composed of 4-6 groups of anchor monomers. The anchor delivery system can realize the implantation of multiple anchor monomers during one operation, greatly shortening the operation time and reducing the physical energy consumption of doctors and patients.

[0031] During operation, the safety button 10 is first pressed, and the safety button 10 releases the restriction on the locking area 75 of the trigger 7, and the trigger 7 is bounced open under the action of the retaining spring 18 and is in a pullable state.

[0032] Secondly, pull the trigger 7, and the toothed area 73 on the trigger drives the driving half gear 191 of the driving member to rotate. The rotation of the driving half gear 191 drives the driving arm 192 to push the driving ratchet 2205 to rotate along the first thread, thereby driving the driving disk 22 to rotate in one direction. During the rotation of the first driving flange 2206 of the driving disk, the restriction of the driving slide 13 is released. Under the action of the driving spring 15, the driving slide 13 moves forward from the rear end of the mounting base plate 12 to the front end of the mounting base plate 12. During this process, the driving slide 13 drives the thread slider 131 to move to the front end of the limiting tongue block and is clamped by the limiting tongue block. During the forward movement of the driving slide 13, the puncture needle 11 is driven by the needle slider 132 to pass through the arc channel at the front end of the delivery pipeline and pierce the lateral lobe of the prostate. During the process of piercing the lateral lobe of the prostate 04, the distal anchor 2602 in the lumen can be driven to enter the outside of the prostate capsule 05.

[0033] Again, pulling the trigger 7 drives the driving disk 22 to rotate along the second thread, that is, through the second driving flange 2207, drives the driving slide 13 to retreat along the mounting base plate 12 and pulls the driving spring 15 to store energy. During this process, the thread slider 131 is stuck by the limiting tongue block 134 and cannot retreat with the driving slide 13, and the coil spring 16 is stretched to store energy; during the retreat of the driving slide 13, the driving slide 13 retreats through the needle slider 132 and drives the puncture needle to be partially retracted along the puncture needle pipeline 201 of the delivery pipeline, and the distal anchor 2602 is released on the outside of the prostate capsule 05, and the front end of the puncture needle 11 is retracted to the urethra side of the prostate 04.

[0034] Once again, the trigger 7 is pulled to drive the drive disk to rotate, and the driving protrusion 2208 lifts the driving column 135 to drive the limit tongue 134 to move upward, releasing the restriction on the wire slider 131. The wire slider 131 is reset backward under the action of the coil spring 16 to pull the anchor wire 2601 to tighten. The wire slider 131 drives the driving slide 13 to complete the reset, and the puncture needle 11 is completely retracted into the delivery pipe 2. During this process, the proximal anchor 2603 is released and deployed on the prostatic urethra side. The position of the moving delivery handle 1 in the urethra makes the breakable point 2604 on the anchor wire 2601 stuck on the cutting edge of the delivery pipe, and the delivery handle 1 is pushed to break the breakable point of the anchor wire, completing the implantation of the anchor monomer.

[0035] During the retraction process of the puncture needle 11, the wire drive mechanism 8 drives the anchor unit to move forward relatively to the front end of the lumen of the puncture needle 11 through different implementation methods (the position of the anchor unit remains unchanged, and the puncture needle moves relatively backward, so that the anchor implant to be implanted is at the implantation position at the front end of the puncture needle). Please see the above statement for details and will not be repeated here.

[0036] Finally, pulling the trigger 7 drives the drive disk 22 to rotate along the third thread, that is, the drive disk rotates so that the guide ring groove 2202 pushes the clamping column 1002 to drive the safety button 10 to move outward and return to the locked state. In this process, the trigger 7 overcomes the elastic force of the retaining spring 18 and returns to the locked state, so as to prepare for the implantation of the next group of anchor monomers.

[0037] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
