Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to a single-hole laparoscopic puncture device. Background Art

[0002] The single-port laparoscopic puncture is a special surgical instrument that is mainly used for laparoscopic techniques in minimally invasive surgery. In clinical applications, the single-port laparoscopic puncture can be used for a variety of laparoscopic surgeries, such as cholecystectomy, appendectomy, hysterectomy, etc. Compared with traditional laparoscopic surgery, the single-port laparoscopic puncture has less trauma, faster recovery speed and better cosmetic effect. It can insert the laparoscope and other surgical instruments through a small incision, thereby reducing bleeding during surgery and postoperative pain. In addition, the use of the single-port laparoscopic puncture can reduce the operation time and postoperative recovery time, allowing patients to recover faster.

[0003] In the prior art, utility model patent CN212234619U discloses a multi-channel single-hole laparoscopic surgical puncture device, including a connector and a flexible sealing cover, wherein the connector includes a channel fixing ring and a platform fixing ring, the bottom of the flexible sealing cover is sleeved on the platform fixing ring and connected to the platform fixing ring, a groove is provided on the inner side wall of the channel fixing ring, a silicone sealing ring is installed in the groove, and a built-in ring is installed in the flexible sealing cover. The multi-channel single-hole laparoscopic surgical puncture device is reasonably designed, and a built-in ring is arranged in the flexible sealing cover, which can provide certain support and facilitate surgical operation. The connector is composed of a platform fixing ring and a channel fixing ring, and has a simple structure. However, in the above technology, if the access channel is too smooth, the instrument may be too smooth in the channel, lose the necessary stability, and increase the possibility of sliding or shifting the instrument, thereby affecting the accuracy and safety of the surgical operation. On the other hand, if the surface friction is too rough, the friction and resistance between the instrument and the channel will be too large, which may cause instrument wear and increase the difficulty of surgery, and may also cause greater trauma to the patient and prolong the postoperative recovery time. Utility Model Content

[0004] The utility model aims to provide a single-port laparoscopic puncture device to solve the problem in the prior art that an access channel is too smooth, which may cause the instrument to be too smooth in the channel, lose the necessary stability, and increase the possibility of sliding or shifting the instrument, thereby affecting the accuracy and safety of the surgical operation. On the other hand, an overly rough surface friction will excessively increase the friction and resistance between the instrument and the channel, which may cause instrument wear and increase the difficulty of the operation, and may also cause greater trauma to the patient and prolong the postoperative recovery time.

[0005] The utility model provides the following technical solution: a single-hole laparoscopic puncture device, comprising a built-in ring, the bottom end of the built-in ring is fixedly connected to a connecting ring, the bottom end of the connecting ring is configured with a fixing ring, the top array of the built-in ring has a plurality of fixed and connected access channels, the inner wall of the access channel is symmetrically fixedly connected to a fixing frame, the internal structure of the fixing frame is a cavity, a plurality of balls are rotatably connected in the fixing frame, the side wall of the access channel is slidably connected to a symmetrical sliding rod, one end of the sliding rod close to each other is fixedly connected to a clamping plate, and the bottom of the sliding rod is provided with a movable component for driving the sliding rod to move.

[0006] The above technical solution provides smoothness, thereby reducing friction and resistance, which helps the instrument pass through the channel more smoothly, reduces instrument wear and surgical difficulty, reduces friction on the patient's wound, and shortens the patient's postoperative recovery time. The sliding rod is controlled by the movable component, allowing the doctor to clamp or release the instrument during the operation as needed, thereby increasing the flexibility and freedom of surgical operations, and further improving stability and ease of control.

[0007] As a preferred embodiment of the above technical solution, the movable component includes a connecting rod fixed to the outer wall of the bottom of the sliding rod, the bottom end of the connecting rod is fixedly connected to a sliding block, one end of the sliding block is provided with a slot, and both side end surfaces of the sliding block are symmetrically provided with limiting openings, the outer wall of the access channel is symmetrically fixed with a fixed platform, and a limiting component is arranged on the top of the fixed platform.

[0008] By adopting the above technical solution, the connecting rod is pushed to make the slider close to the limiting assembly, and the limiting assembly fixes the position of the slider, thereby fixing the position of the sliding rod and the clamping plate, thereby improving the stability of the instrument inside the access channel.

[0009] As a preferred embodiment of the above technical solution, the limit assembly includes a fixed block fixedly connected to the top surface of the fixed platform, an insertion block is fixedly connected to one side of the fixed block, telescopic grooves are symmetrically opened inside the insertion block, telescopic rods are symmetrically fixed on inner walls of the telescopic grooves close to each other, a telescopic spring is wound around the outer wall of the telescopic rod, and the ends of the telescopic rods far away from each other are fixedly connected to the limit block.

[0010] By adopting the above technical solution, the limit block is subjected to pressure to drive the telescopic rod and the telescopic spring to shrink into the telescopic groove. After the limit block reaches the limit opening along the inner wall of the slider, the limit block is no longer subjected to force. At this time, the telescopic spring drives the telescopic rod and the limit block to start extending, and the limit block is inserted into the limit opening. The plane of the limit block contacts the inner wall of the limit opening, thereby limiting the slider.

[0012] The adoption of the above technical solution improves the stability of the telescopic spring and the limit block, and further enhances the limit effect.

[0017] As a preferred embodiment of the above technical solution, the end surfaces of the clamping plates that are close to each other are arc-shaped surfaces.

[0018] By adopting the above technical solution, the clamping plate can fit the outer wall of the surgical instrument more closely when contacting the surgical instrument, thereby making the clamping effect tighter, and enhancing the applicability and stability during surgery.

[0020] When the utility model needs to perform an operation, the surgical instrument is inserted through the access channel, and the ball contacts the outer wall of the instrument at this time. When the instrument reaches the position completely, the position of the sliding rod is adjusted by controlling the movable component. When the sliding rods are close to each other, the clamping plate fixes and clamps the outer wall of the instrument. When the sliding rods are away from each other, the clamping plate does not limit the instrument. The contact between the ball and the outer wall of the instrument can provide it with smoothness, thereby reducing friction and resistance, which helps the instrument to pass through the channel more smoothly, reduces instrument wear and surgical difficulty, reduces friction on the patient's wound, and shortens the patient's postoperative recovery time. The sliding rod is controlled by the movable component, which allows the doctor to clamp or release the instrument as needed during the operation, thereby increasing the flexibility and freedom of surgical operations and further improving stability and convenience of control.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] like Figure 1-5 As shown, the utility model provides a technical solution: a single-port laparoscopic puncture device, comprising an internal ring 100, a connecting ring 101 is fixedly connected to the bottom end of the internal ring 100, a fixing ring 102 is configured at the bottom end of the connecting ring 101, a top array of the internal ring 100 has a plurality of fixed and connected access channels 200, a fixing frame 201 is symmetrically fixedly connected to the inner wall of the access channel 200, the internal structure of the fixing frame 201 is a cavity, a plurality of balls 202 are rotatably connected in the fixing frame 201, a symmetrical sliding rod 203 is slidably connected to the side wall of the access channel 200, a clamping plate 204 is fixedly connected to one end of the sliding rod 203 close to each other, and a movable component for driving the sliding rod 203 to move is arranged at the bottom of the sliding rod 203.

[0029] Specifically, when surgery is required, the surgical instrument is inserted through the access channel 200, at which time the ball 202 contacts the outer wall of the instrument. When the instrument reaches the full position, the position of the sliding rod 203 is adjusted by controlling the movable component. When the sliding rods 203 are close to each other, the clamping plate 204 fixes and clamps the outer wall of the instrument. When the sliding rods 203 are away from each other, the clamping plate 204 does not limit the instrument. The contact between the ball 202 and the outer wall of the instrument can provide it with smoothness, thereby reducing friction and resistance, which helps the instrument to pass through the channel more smoothly, reduces instrument wear and surgical difficulty, reduces friction on the patient's wound, and shortens the patient's postoperative recovery time. Controlling the sliding rod 203 through the movable component can allow the doctor to clamp or release the instrument as needed during the operation, thereby increasing the flexibility and freedom of surgical operations, and further improving stability and ease of control.

[0030] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, the movable component includes a connecting rod 300 fixed to the outer wall of the bottom of the sliding rod 203, the bottom end of the connecting rod 300 is fixedly connected to a slider 301, one end of the slider 301 is provided with a slot 302, and both side end surfaces of the slider 301 are symmetrically provided with limit openings 303, the outer wall of the access channel 200 is symmetrically fixed with a fixed platform 400, and a limit assembly is arranged on the top of the fixed platform 400. By controlling the connecting rod 300, the slider 301 is located on the top surface of the fixed platform 400 to slide, and at the same time, the sliding rod 203 and the clamping plate 204 are driven to move away from or approach each other. When it is necessary to clamp the surgical instrument, the connecting rod 300 is pushed to make the slider 301 approach the limit assembly, and the limit assembly fixes the position of the slider 301, thereby fixing the positions of the sliding rod 203 and the clamping plate 204, thereby improving the stability of the instrument inside the access channel 200.

[0031] As an implementation method in this embodiment, Figure 3 , Figure 4 and Figure 5 As shown, the limit assembly includes a fixed block 401 fixedly connected to the top surface of the fixed platform 400, a plug block 402 is fixedly connected to one side of the fixed block 401, telescopic grooves 403 are symmetrically opened inside the plug block 402, telescopic rods 404 are symmetrically fixed on the inner walls of the telescopic grooves 403 close to each other, a telescopic spring 405 is wound around the outer wall of the telescopic rod 404, and the ends of the telescopic rod 404 far away from each other are fixedly connected to the limit block 406.

[0032] Specifically, when the slider 301 approaches the fixed block 401, the insert block 402 is inserted into the slot 302. At this time, the side wall of the slider 301 contacts the arc surface of the limit block 406. The limit block 406 is subjected to pressure to drive the telescopic rod 404 and the telescopic spring 405 to retract into the telescopic groove 403. After the limit block 406 reaches the limit opening 303 along the inner wall of the slider 301, the limit block 406 is no longer subjected to force. At this time, the telescopic spring 405 drives the telescopic rod 404 and the limit block 406 to start extending, and the limit block 406 is inserted into the limit opening 303. The plane of the limit block 406 contacts the inner wall of the limit opening 303, thereby limiting the slider 301. When it needs to be released, press the limit blocks 406 on both sides. At this time, the limit blocks 406 do not limit the slider 301, and the connecting rod 300 can be moved out.

[0033] As an implementation method in this embodiment, Figure 4 As shown, one end of the telescopic spring 405 is fixedly connected to the inner wall of the telescopic slot 403, and the other end of the telescopic spring 405 is fixedly connected to the limit block 406, thereby improving the stability of the telescopic spring 405 and the limit block 406 and further improving the limiting effect.

[0034] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, the slider 301 is matched with the insert block 402, and the limit opening 303 is matched with the limit block 406, so as to reduce the redundant gap, prevent the shaking and wear caused by the fixation, and further improve the fixation and service life.

[0035] As an implementation method in this embodiment, Figure 5 As shown, a limit groove 407 is provided on the top surface of the fixed platform 400, and a limit bar 304 is fixedly connected to the bottom surface of the slider 301. The limit bar 304 is slidably connected to the limit groove 407. The sliding of the limit bar 304 and the limit groove 407 provides further limitation for the slider 301, so that it can maintain a stable trajectory to drive the sliding rod 203 and the clamping plate 204 to slide.

[0036] As an implementation method in this embodiment, Figure 2 and Figure 3 As shown, the end faces of the clamping plate 204 that are close to each other are arc-shaped, so that the clamping plate 204 can fit more closely to the outer wall of the surgical instrument when contacting the surgical instrument, making the clamping effect tighter, thereby enhancing the applicability and stability during surgery.

[0037] Working principle: When surgery is required, the surgical instrument is inserted through the access channel 200. At this time, the ball 202 contacts the outer wall of the instrument and pushes the connecting rod 300. The connecting rod 300 slides on the top surface of the fixed platform 400. The connecting rod 300 drives the sliding rod 203 and the clamping plate 204 to approach each other to clamp the surgical instrument in the access channel 200. At the same time, the slider 301 approaches the fixed block 401, and the insert block 402 is inserted into the slot 302. At this time, the side wall of the slider 301 contacts the limit The limit block 406 is subjected to pressure to drive the telescopic rod 404 and the telescopic spring 405 to retract into the telescopic groove 403. After the limit block 406 reaches the limit opening 303 along the inner wall of the slider 301, the limit block 406 is no longer subjected to force. At this time, the telescopic spring 405 drives the telescopic rod 404 and the limit block 406 to start extending. The limit block 406 is inserted into the limit opening 303. The plane of the limit block 406 contacts the inner wall of the limit opening 303, thereby limiting the slider 301.

[0038] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
