Description

Technical Field

[0001] The invention belongs to the technical field of staplers, and in particular relates to a cervical conization stapler. Background Art

[0002] Cervical conization is a gynecological surgery to remove the cervix, which means cutting off a part of the cervical tissue in a cone shape from the outside to the inside. On the one hand, it is for pathological examination and diagnosis of cervical lesions; on the other hand, it is also a treatment method to remove lesions.

[0003] When high-grade lesions appear in the cervical epithelium, the doctor will recommend the patient to undergo a diagnostic cervical conization. Cervical conization is generally divided into two types: electrosurgical excision (LEEP knife) and cold knife conization. The LEEP knife is operated with a high-frequency electric knife. Its advantages are short operation time, less bleeding, fewer complications, good cervical shaping, no need for hospitalization, and short operation time. Cold knife conization is a traditional scalpel excision. Its advantages are clear cutting edges and conducive to pathological examination. Its disadvantages are the need for hospitalization, anesthesia, long operation time, and high intraoperative bleeding.

[0004] At present, most cervical conization surgeries need to retain pathological tissue to facilitate subsequent pathological examination. Therefore, most cervical conization surgeries are performed using cold knife conization, but cold knife conization has disadvantages such as long operation time and high intraoperative bleeding. Therefore, there is a need for a cervical conization stapler that can use the stapler to quickly suture the cone cut, thereby greatly reducing the operation time of cold knife conization, improving the treatment efficiency of cold knife conization wounds, and effectively reducing the amount of bleeding during cold knife conization, while meeting the requirements for obtaining cervical pathological tissue.

[0005] In addition, due to the differences in cervical lesions, the range of cervical cone biopsy is not the same. Before the traditional cold knife cone biopsy, the doctor needs to determine the range of cone biopsy based on the patient's diagnosis results. However, most of the existing cervical cone biopsy devices are unable to adjust the range of cervical cone biopsy according to the degree of cervical lesions. In order to ensure the effect of cervical cone biopsy, the existing cervical cone biopsy devices will expand the cone biopsy angle as much as possible, increase the patient's cervical cone biopsy range, and lead to increased bleeding during cervical cone biopsy, affecting the postoperative effect of cervical cone biopsy, and causing additional damage to the patient's body, increasing intraoperative and postoperative risks.

[0006] A Chinese patent with the authorization announcement number CN112998789B discloses an intracavitary cutting stapler with a larger rotation angle, comprising a shell, a connecting tube fixedly connected to one side of the shell, one end of the connecting tube being connected to the interior of the shell, a retaining ring being provided at one end of the connecting tube, a rotating disk and a rotating ring being rotatably connected to the two sides of the retaining ring, an outer tube being provided at one side of the rotating ring, an inner tube being rotatably connected to the inner side of the outer tube, one end of the inner tube being rotatably connected to one side of the rotating ring, and a first clamp and a second clamp being symmetrically provided at one end of the inner tube; the invention has a reasonable structure, the rotating disk drives the rotating rod to rotate through the transmission shaft and the active bevel gear and the driven bevel gear, thereby driving the first clamp and the second clamp to swing to both sides, the rotating ring drives the connecting plate to rotate through the inner tube and the fixed ring to rotate circumferentially, thereby driving the entire end actuator to rotate circumferentially, thereby obtaining a larger rotation angle, which is convenient for finding a suitable suturing position; the limiting portion formed by the cooperation of the external threaded tube and the fastening screw sleeve provides a simple and reliable locking mechanism. This application enables the end actuator of the stapler to swing to both sides and rotate circumferentially, and can obtain a larger rotation angle, which is convenient for finding a suitable suturing position. Although the intracavitary cutting stapler with a larger rotation angle can obtain a larger rotation angle, it is not suitable for cervical conization. It is difficult to achieve conical resection of the cervix during cervical conization, which affects the postoperative effect of cervical conization. Summary of the invention

[0043] The method according to the above-mentioned cervical conization stapler comprises the following steps; Step 1: Treatment before cervical conization and suture; Before the patient undergoes cervical conization and suturing, the patient needs to check and confirm the degree of cervical lesions to facilitate the selection of an appropriate conization range. Use gear key 2 to select an appropriate conization gear. After the cervical conization and suturing instrument is disinfected, install the suture staples in the staple grooves of the appropriate concentric ring tubes as needed.

[0044] Step 2: Adjustment of the cone cutting assembly 6; Use Figure 2 The cervical conization suture device is shown in the state of entering the cervix. Before cervical conization, the cervical conization suture device is inserted into the cervix to a certain depth according to the degree of cervical lesions. The insertion depth is judged to be accurate according to the scale on the conization sleeve 1. After the insertion is completed, the conization component 6 is located at the cervix, and the push switch 4 is pulled. The cervical conization suture device automatically adjusts the conization component 6 and the suturing component 5 according to the set gear position. The clamping motor releases the clamping shaft 603. Under the action of the clamping spring, the fan ring clamping plate 602 rotates along the clamping shaft 603, so that the clamping fan rings 601 are close to each other, and the conical head 604 is clamped on the cervix to prevent the cervix from shifting during conization and improve the conization effect.

[0045] Then, the position adjustment motor 606 is started, and the position of the cone cutting ring 605 in the cone cutting sleeve 1 is adjusted according to the selected gear key 2. The movable end of the position adjustment motor 606 is meshed with the inner rack in the cone cutting sleeve 1, driving the cone cutting slider 608 of the cone cutting bearing 607 to move along the cone cutting slide groove, so that the cone cutting ring 605 is close to or away from the stapler 501, and the cone cutting ring 605 pushes the cone cutting connecting rod 610 to move. As the cone cutting connecting rod 610 moves, the cone cutting knife 611 The guide telescopic cylinder 612 is driven to move along the guide groove into the cone cutting groove of the fan ring, and the magnetic ring 615 moves into the cone cutting guide groove; along with the movement of the cone cutting connecting rod 610, the cone cutting connecting rod 610 moves in the inclined cone cutting guide groove in the cone cutting sleeve 1. Due to the inclined setting of the cone cutting guide groove, the cone cutting connecting rod 610 is adjusted at a small angle along the cone cutting rotating shaft 609, so as to realize the adjustment action of the cutting angle of the cone cutting knife 611, and the guide telescopic cylinder 612 is extended and retracted along with the angle adjustment of the cone cutting knife 611.

[0046] Step 3: Adjustment of the suturing assembly 5; Before suturing the cervix, the position of the stapler 501 is adjusted, and the movable end of the sleeve motor drives the suturing sleeve 503 to rotate on the cone cutting sleeve 1 along the suturing bearing 504 through the suturing outer gear 507, and the threaded inner cylinder 508 is threadedly engaged with the suturing sleeve shaft 505, so that the suturing sleeve shaft 505 moves along the linear bearing 506 on the cone cutting ring cylinder 605, thereby realizing the telescopic adjustment of the suturing sleeve shaft 505. Through the telescopic adjustment of the suturing sleeve shaft 505, the distance between the stapler 501 and the conical head 604 is reduced or increased, and through the adjustment of the position of the stapler 501, the distance between the stapler magazine and the staple support seat of the stapler 501 is reduced or increased, so as to facilitate the preliminary adjustment of the suturing position of the suturing staple according to the cone cutting requirements.

[0047] After the adjustment of the suturing sleeve shaft 505 is completed, the cone cutting knife 611 can be accurately adjusted again through the cone cutting adjuster 502, and the cone cutting adjustment motor 510 drives the cone cutting adjustment cylinder 513 to rotate on the suturing sleeve shaft 505, and the thread in the cone cutting adjustment cylinder 513 is engaged with the thread on the cone cutting adjustment screw 512, driving the cone cutting adjustment screw 512 to rotate along the cone cutting adjustment bearing 516. As the cone cutting adjustment screw 512 rotates, the cone cutting rotating cylinder 514 moves along the cone cutting adjustment screw 512, and the cone cutting adjustment plate 511 moves with the cone cutting rotating cylinder 514. The cone cutting adjustment plate 511 drives the cone cutting connecting rod 610 to rotate along the cone cutting rotating shaft 609 through the cone cutting adjustment shaft 515, and further adjusts the angle of the cone cutting connecting rod 610, thereby achieving further precise adjustment of the cone cutting knife 611, so that the adjusted cone cutting knife 611 can adapt to the cone cutting requirements of cervical lesions.

[0048] After the cone cutting is completed, the telescopic connecting rod in the cone cutting connecting rod 610 contracts, driving the cone cutting connecting rod 610 to contract and exit the clamping fan ring 601, and then the position of the suturer is adjusted to make it reach the cone cutting wound. The propulsion motor 528 on the side of the inner ring 527 of the truncated cone bearing is engaged with the propulsion rack 530 on both sides of the bearing guide groove 519, driving the truncated cone sleeve 517 and the truncated cone bearing 520 to move along the bearing guide groove 519 toward the clamping fan ring 601 through the bearing boss 526, so that it is close to the cone cutting wound. After moving into place, according to the needs of the cone cutting wound, the suture push rod 521 pushes the suture connecting rod 523 to move in the suture slide groove 522, so that the suture piece 518 is adjusted to a suitable position. Since the side of the truncated cone sleeve 517 is a slope and the suture slide groove 522 is an inclined slide groove, the suture piece 518 moves in the inclined suture slide groove 522 to achieve the adjustment of the inclination angle of the suture piece 518, thereby meeting the suture requirements of the cone cutting wound.

[0049] Step 4: Conization and suturing of the cervix; After the adjustment of the cone cutting component 6 and the suturing component 5 is completed, the cervical lesion is subjected to cold knife cone cutting and suturing by adopting the method of cone cutting first and then suturing; during cone cutting, the cone cutting motor 613 drives the cone cutting component 6 to rotate along the cone cutting bearing 607 through the cone cutting ring tube 605, and the cone cutting connecting rod 610 drives the cone cutting knife 611 to rotate along the fan ring cone cutting groove, and the magnetic ring 615 moves in the cone cutting guide groove along the guide bearing 614, and the rotating cone cutting knife 611 performs cone cutting on the cervical lesion position, and the cone cutting is completed. After the cutting is completed, the cone cutting knife 611 is adjusted to a suitable position. At this time, the guide telescopic cylinder 612 is located at the connection between the guide groove and the fan ring cone cutting groove, the telescopic connecting rod contracts, driving the cone cutting connecting rod 610 to contract, and the guide telescopic cylinder 612 enters the guide groove along the fan ring cone cutting groove. The cone cutting connecting rod 610 drives the cone cutting knife 611 to withdraw from the cervical cone cutting area, and the cone cutting thorn on the back of the cone cutting knife 611 brings the cone-cut cervical tissue out of the clamping fan ring 601, thereby obtaining the cervical pathological tissue.

[0050] After the cone cutting knife 611 is withdrawn and before suturing, one end of the suture thread 536 is interference fit in the pressure hole 538 at the end of the suture thread rod 533, and the suture piece 518 of the suture device is used to suture the cone cutting wound. The suture motor drives the suture eccentric wheel to rotate in the suture cavity, and the suture eccentric wheel pushes the smooth ball convex through the suture ring groove on the convex side to make the suture needle 534 telescopically move along the suture channel and insert it into the tissue on the inner side of the cervical wound after the cone cutting. The hook groove on the suture needle 534 is inserted and moved between the two suture rods 531 of the suture frame 535, and the suture thread 536 slides into the hook groove. The suture needle 534 is reset under the action of the suture spring. At this time, the smooth ball convex of the suture needle 534 is in the suture ring groove on the concave side of the suture eccentric wheel. Inside, the suture needle 534 pulls the suture thread 536 through the hook groove and returns along the hole penetrated by the suture needle 534. The suture coil in the suture cavity provides traction for the suture thread 536 for the suture needle 534 through the coil channel along the suture hole 537 at the end of the suture rod 531. The first stitch of the cone wound is completed. After the first stitch, the truncated table motor drives the truncated table sleeve 517 to rotate a certain angle along the truncated table bearing 520 through the suture gear 525, and the suture piece 518 sutures the cone wound again. Repeating the above actions can achieve rapid suturing of the cone wound. The suture coil in the suture cavity is disposable and a certain length is reserved. After the suturing is completed, the cervical cone suture device is withdrawn and the surgeon ties a knot on the suture thread 536.

[0051] After the first stitch is completed, when the second stitch is sutured, the hook groove on the suture needle 534 continues to pull the suture thread 536 pulled by the first stitch. When the suture needle 534 is inserted into the inner tissue of the cone-cut wound again, since the top of the anti-detachment blocking rod on the opening side of the hook groove is a cone, the suture thread 536 pulled by the first stitch will be separated from the hook groove and temporarily remain in the hole penetrated by the second stitch. Due to the overall rotation of the suture piece 518, the end of the suture thread 536 that is interference-fixed in the thread pressing hole 538 at the end of the suture rod 533 is separated from the thread pressing hole 538. The overall rotation angle of the suture piece 518 is small, and the suture 536 compressed by the muscle tissue will not be separated from the first penetration hole; after the suture needle 534 pulls the suture 536 between the root suture frame 535 again and returns, the second traction suture 536 will squeeze the first traction suture 536 into the second penetration hole, forming a tissue fixation for the first traction suture 536 part, repeating the above movement to achieve the suture treatment of the cone cut wound. It should be noted that the second suture needle and the last suture needle overlap to avoid derailment. The electric equipment such as the motor and push rod used in this embodiment is a customized device, and its size and power can meet the needs of cervical cone cut and suture.
