Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of medical devices, and in particular relates to an auxiliary suturing and cutting device for a prostate body. Background Art
[0002] In the field of prostate surgery, suturing and cutting operations are key steps to ensure the success of the operation and the patient's postoperative recovery.
[0003] Currently, assisted suturing and thread cutting methods in prostate surgery mainly rely on traditional instruments and manual operations. Some medical institutions use simple needle holders and scissors for suturing and thread cutting. During the operation, the doctor must first manually cut the estimated length of suture, then use the needle holder to clamp the suture needle to suture the wound, and then use scissors to cut the suture after the suturing is completed. There are also some more advanced auxiliary equipment that use robotic arms to assist in positioning the suture needle. However, manual intervention by medical staff is still required in the suture management and disinfection process, such as manually applying disinfectant to disinfect the suture.
[0004] However, the existing auxiliary suture cutting method has the following defects in actual use: first, it is difficult to accurately control the length of the suture when manually cutting it, and there is often a situation where the suture is insufficient, resulting in interruption of the operation or the suture is cut too long, resulting in waste, which not only affects the surgical process but also increases medical costs. Second, there is a lack of an automatic wire arrangement structure, and the suture is very easy to get entangled and knotted during use. The doctor needs to spend a lot of time to deal with it, which seriously reduces the suturing efficiency. Third, the disinfection of the suture is mostly done by manually applying disinfectant, which cannot be carried out simultaneously with the suturing operation, and the disinfection effect is difficult to guarantee. There is a high risk of infection. In view of this, the present invention is specially proposed. Summary of the Invention

DETAILED DESCRIPTION
[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.
[0030] Example 1: Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7, an auxiliary suturing and cutting device for prostate body, comprising a wire storage box 1, and also comprising: a rotating shaft 2 and a reciprocating screw rod 4, both of which are rotatably connected to the wire storage box 1; a wire storage roller 3, which is detachably connected to the rotating shaft 2; a guide rod 401, which is fixedly connected to the wire storage box 1; a moving block 402, which is slidably connected to the guide rod 401 and is threadedly connected to the reciprocating screw rod 4, wherein a lead hole 403 is provided on the moving block 402; a lead tube 103, which is detachably connected to the wire storage box 1 through a connecting head 102 and is connected to the inside of the wire storage box 1, wherein the suture wound on the wire storage roller 3 passes through the lead hole 403 in turn, and the lead tube 103 is connected to the suture needle; an infusion cavity 5, which is opened between the inner and outer walls of the lead tube 103, wherein a plurality of spray holes 501 are equidistantly opened on the inner wall of the lead tube 103; an infusion tube 2 507, which is connected to the lead tube 103 and is connected to the infusion cavity 5.
[0031] Pulleys are fixedly mounted on the rotating shaft 2 and the reciprocating screw rod 4 , and the two pulleys are connected by a belt 404 .
[0032] A sleeve 502 is fixedly installed on the inner walls of both sides of the wire storage box 1, and a piston disk 503 is slidably connected inside the sleeve 502. A liquid storage chamber 506 is provided in the wire storage box 1. The sleeve 502 is connected to the liquid storage chamber 506 through an infusion tube 1 505, and an end of an infusion tube 2 507 away from the infusion chamber 5 is connected to the sleeve 502; a connecting rod 504 is fixedly connected to the piston disk 503 at one end and fixedly connected to the moving block 402 at the other end.
[0033] When a suture needle is used to suture a wound, the suture needle pulls the suture thread to move, and the suture thread pulls the storage roller 3 when moving, driving the rotating shaft 2 to rotate, thereby releasing the suture thread. At the same time, when the rotating shaft 2 rotates, the reciprocating screw rod 4 is driven to rotate by the belt 404, and the reciprocating screw rod 4 drives the moving block 402 to move back and forth under the guidance of the guide rod 401. The reciprocating motion of the moving block 402 drives the lead hole 403 to move synchronously, thereby achieving uniform payout of the suture thread on the storage roller 3, avoiding the problem of suture thread entanglement and knotting, improving suturing efficiency, and reducing time wasted due to dealing with entanglement.
[0034] At the same time, when the moving block 402 reciprocates, the connecting rod 504 drives the piston disc 503 to reciprocate synchronously in the sleeve 502. When the piston disc 503 moves outward, a negative pressure is formed in the sleeve 502, and the alcohol in the liquid storage chamber 506 is sucked into the sleeve 502 through the infusion tube 1 505. When the piston disc 503 moves inward, the liquid in the sleeve 502 is pressurized and injected into the infusion chamber 5 through the infusion tube 2 507, and finally evenly sprayed on the suture thread through the spray hole 501, which is used to moisten and disinfect the suture thread, which not only ensures the sterility of the suture thread, but also reduces the The infection risk is reduced, and the safety and success rate of the operation are improved. The disinfection and wetting process are carried out simultaneously with the suturing operation, and no additional operation is required, which improves work efficiency. Both the infusion tube 1 505 and the infusion tube 2 507 are provided with a one-way valve, wherein the setting of the wire storage roller 3 can store enough sutures, which solves the problem of insufficient or excessive sutures that may occur when medical staff intercept an appropriate amount of sutures in the prior art, avoids the suturing process being affected by insufficient sutures, and also prevents the waste caused by excessive suture interception, thereby achieving efficient use of sutures.
[0035] Example 2: Reference Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 , an auxiliary suturing and cutting device for the prostate body is basically the same as Example 1. Furthermore, a rotating sleeve 202 is rotatably connected to the wire storage box 1, and the rotating sleeve 202 is symmetrically arranged with the rotating shaft 2. A sliding rod 203 is slidably connected to the rotating sleeve 202, and the sliding rod 203 and the rotating shaft 2 are fixedly connected with a clamping disk 201. The clamping disk 201 and the two ends of the wire storage roller 3 are abutted, and one end of the sliding rod 203 away from the clamping disk 201 is fixedly connected to the limiting block; a tension spring 204 sleeved on the sliding rod 203 is fixedly connected to the limiting block at one end, and the other end is fixedly connected to the rotating sleeve 202; a limiting component is arranged on the rotating sleeve 202, and is used for the sliding rod 203 to rotate synchronously with the rotating sleeve 202.
[0036] The upper end of the wire storage box 1 is open, and the upper end of the wire storage box 1 is detachably connected to a cover plate 101 via fixing bolts.
[0037] The limiting component includes a guide groove 205 , which is formed on the outer wall of the slide rod 203 . A guide block is integrally formed on the inner wall of the rotating sleeve 202 , and the guide block is slidably connected to the guide groove 205 .
[0038] Install the storage roller 3: Unscrew the fixing bolts and remove the cover 101. Pull the slide bar 203 outward to stretch the tension spring 204. Slide the storage roller 3 onto the rotating shaft 2 and position it between the two clamping plates 201. Loosen the slide bar 203. Under the elastic force of the tension spring 204, the clamping plates 201 clamp the storage roller 3. Replace the cover 101 and tighten the fixing bolts.
[0039] Suturing operation: When the suture needle pulls the suture thread to move, the suture thread drives the thread storage roller 3 to rotate. The thread storage roller 3 drives the clamping disk 201, the rotating shaft 2 and the slide bar 203 to rotate synchronously through the friction force. The slide bar 203 drives the rotating sleeve 202 to rotate synchronously through the cooperation of the guide groove 205 and the guide block.
[0040] Synchronous wire arrangement and disinfection: The rotation of the rotating shaft 2 drives the reciprocating screw 4 to rotate through the belt 404, so that the moving block 402 moves back and forth to achieve wire arrangement. The moving block 402 drives the piston plate 503 to reciprocate through the connecting rod 504 to achieve alcohol-moistened disinfection of the suture thread;
[0041] Replacement of the wire storage roller 3: Unscrew the fixing bolts and remove the cover plate 101, pull the slide bar 203 outward, take out the used wire storage roller 3, replace it with a new one and install it according to the above steps.
[0042] In summary, the elastic deformation of the tension spring 204 is used to generate a clamping force, and the storage roller 3 can be quickly installed and removed by pulling the slide bar 203. The detachable connection of the cover plate 101 provides an operating space for the replacement of the storage roller 3.
[0043] The guide groove 205 and the guide block slide together to transmit the rotation of the slide rod 203 to the rotating sleeve 202, ensuring that both ends of the storage roller 3 rotate synchronously, thus avoiding jamming or wear caused by uneven torque.
[0044] The cover plate 101 is tightly connected to the wire storage box 1 by fixing bolts to form a closed space, which prevents external dust and liquid from entering and contaminating the internal mechanism, and protects the operator from being hurt by moving parts.
[0045] Example 3: Reference Figure 6 , a device for assisting in-vivo suturing and cutting of the prostate, which is basically the same as that of Example 1, and furthermore, the guide tube 103 is arranged in an arc shape near the spray hole 501.
[0046] The arc portion of the lead tube 103 is fixedly connected to a connecting sleeve 508 , and a collecting tank 509 is threadedly connected to the connecting sleeve 508 .
[0047] When the piston disc 503 moves inward, alcohol is evenly sprayed onto the suture thread through the spray hole 501 at a flow rate of 0.5-1 ml / s, completing the disinfection and wetting. Since the entire device is tilted at 45 degrees when in use, the sprayed alcohol flows into the arc section of the guide tube 103 under the action of gravity, and finally gathers at the lowest point of the arc section, and then flows into the collection tank 509 through the connecting sleeve 508. The collection tank 509 adopts a transparent design, allowing medical staff to visually observe the liquid level and thus handle it in time;
[0048] In summary, the arc-shaped structure and the inclined setting guide the alcohol to flow into the collection tank 509, preventing the disinfectant from flowing into the patient's body, greatly reducing the risk of postoperative infection caused by residual disinfectant, and providing a strong guarantee for surgical safety.
[0049] The design of the arc structure and the connecting sleeve 508 enables alcohol to flow into the collection tank 509 efficiently, thereby improving the collection efficiency. The transparent tank body allows medical staff to observe the liquid level in real time without the need for frequent disassembly and inspection. When processing is required, the collection tank 509 can be quickly unscrewed for operations such as pouring the liquid, reducing maintenance time and workload and improving the fluency and efficiency of surgical operations.
[0050] Example 4: Reference Figure 6 、 Figure 8 , a device for assisting suturing and cutting in the prostate, which is basically the same as Example 1, is further characterized in that a knife seat 6 is integrally formed near the outlet end of the wire guide tube 103, and a wire outlet groove is provided on the knife seat 6. A slide groove 601 is provided on the wall of the wire outlet groove, and a cutter 602 is slidably connected in the slide groove 601. A spring 603 is provided in the slide groove 601, and one end of the spring 603 is fixedly connected to the wall of the slide groove 601, and the other end is fixedly connected to the upper end surface of the cutter 602. An installation cavity is provided between the inner and outer walls of the wire guide tube 103, and an electromagnet 604 is fixedly installed on one side of the installation cavity, and an adsorption block 606 is slidably connected in the installation cavity; a pull rope 605 is fixedly connected to the adsorption block 606 at one end, and fixedly connected to the cutter 602 at the other end.
[0051] Standby state: the electromagnet 604 is energized, the adsorption block 606 is magnetically adsorbed, the cutter 602 is kept in the initial position above the slide 601 by the pull rope 605, the spring 603 is in a compressed state, the outlet slot is unobstructed, and the suture thread can pass freely;
[0052] During the suturing process, when it is necessary to cut the suture thread, the medical staff steps on the foot-operated control switch to cut off the power to the electromagnet 604. At this time, the magnetic force disappears, and the spring 603 compressed in the initial state generates a thrust, pushing the cutter 602 to slide rapidly downward in the slide groove 601. When the cutter 602 slides to contact the lower end of the knife holder 6, the blade of the cutter 602 cuts the suture thread located in the outlet groove. As the cutter 602 slides downward, the pull rope 605 pulls the adsorption block 606 to slide in the installation cavity to the side away from the electromagnet 604.
[0053] After cutting, the medical staff steps on the foot control switch again to energize the electromagnet 604, generating magnetic force to attract the adsorption block 606. The adsorption block 606 pulls the cutter 602 through the pull rope 605 to overcome the thrust of the spring 603 and slide upward back to the initial position, waiting for the next cutting operation.
[0054] In summary, the movement of the cutter 602 is controlled by the electromagnet 604, which is convenient and quick to operate and can automatically and accurately cut the suture. The spring 603 automatically resets the cutter 602, ensuring the continuity and stability of the device. At the same time, the cutter 602 is inside the guide tube 103, which can avoid damage to external tissues during the cutting process.
[0055] Example 5: Reference Figure 1 、 Figure 6 , a device for assisting in-vivo suturing and cutting of the prostate, which is substantially the same as that of Example 1, and furthermore, a connector 102 is fixedly connected to the wire storage box 1, and a wire guide tube 103 is threadedly connected to the connector 102;
[0056] After the operation, rotate the guide tube 103 counterclockwise to remove it from the connector 102. At this time, the guide tube 103 can be soaked in disinfectant, or a special cleaning tool can be used to rinse deeply inside through the outlet end to remove residual blood and disinfectant. After cleaning and disinfection, check whether the threaded surfaces of the guide tube 103 and the connector 102 are damaged. After confirmation, repeat the initial assembly steps to ensure a firm connection for the next use. This detachable design makes the interior of the guide tube 103 clean without dead corners, reducing the risk of cross infection compared to the non-detachable design.
[0057] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as above with the preferred embodiment, it is not intended to limit the present invention.
