Description

Technical Field

[0001] The invention relates to a surgical instrument, in particular to a puncture, flushing and suturing component. Background Art

[0002] With the promotion of minimally invasive technology, laparoscopic surgery or various types of surgery under Da Vinci have gradually become the mainstream surgical procedures. However, before performing laparoscopic surgery, especially extraperitoneal or retroperitoneoscopic surgery in urology, it is necessary to expand the extraperitoneal cavity before surgery in order to obtain a larger operating space after establishing the laparoscopic channel. At the same time, after the operation, we need to suture the lumbar fascia or muscle fascia to reduce postoperative wound bleeding and the probability of incisional hernia.

[0003] Existing laparoscopic surgeries usually use dilators, puncture devices, and staplers in sequence, so that doctors need to repeatedly insert and remove different instruments during the operation. Specifically, after the doctor uses the dilator to complete the expansion of the extra-abdominal cavity, the dilator must be removed first, and then the puncture device is inserted to cooperate with the endoscope and surgical instruments for surgery. After the operation is completed, the puncture device needs to be removed again and the stapler is inserted to suture the fascia in the abdominal cavity. Sometimes, in order to have a clearer surgical field of view, the doctor will also insert a flusher to flush the surgical area of ​​the extra-abdominal cavity. The entire surgical process requires the insertion and removal of dilators, puncture devices, flushers, and staplers in sequence through the surgical skin incision, which may not only cause accidental injuries to the patient and increase the risk of postoperative complications such as wound bleeding and incisional hernia, but may also require the doctor to observe and adjust the position of the instrument inserted into the human body after each insertion of a different instrument, which prolongs the operation time, which may lead to uncontrollable surgical risks.

DETAILED DESCRIPTION

[0063] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0064] Example 1

[0065] like Figure 1-9 As shown, this embodiment provides a puncture flushing suturing assembly, which includes: a puncture device 100, a dilator 200, a flusher 300 and a suturing device 400. The puncture device 100 includes a sheath 110 and a puncture sheath needle 120 that is detachable from the sheath 110. The sheath 110 includes a cylindrical puncture tube 111, and a hollow channel 1111 is arranged inside the puncture tube 111 along its axial direction. The puncture tube 111 includes a puncture end and an operating end located at both ends of the hollow channel 1111. When the puncture sheath needle 120 is inserted into the hollow channel 1111, the needle tip of the puncture sheath needle 120 extends out of the puncture end of the hollow channel 1111. The inner diameter of the hollow channel 1111 can be selected as 10mm or 12mm to adapt to existing commonly used surgical instruments. Of course, the inner diameter size of the hollow channel 1111 can also be designed and produced according to actual needs.

[0066] The expander 200 includes an elastic balloon 210, which can expand after being inflated and recover after being deflated. When the expander 200 is installed in conjunction with the sheath 110, the elastic balloon 210 can extend out of the puncture end of the hollow channel 1111. During surgery, one end of the elastic balloon 210 of the expander 200 is inserted into the human body through the hollow channel 1111 of the sheath 110, and then the elastic balloon 210 is inflated, so that the elastic balloon 210 expands to push away the soft tissue around the gap under the skin incision to form a space for laparoscopic surgery. After the surgical space is formed, the elastic balloon 210 is deflated and the expander 200 is taken out of the hollow channel 1111 of the sheath 110.

[0067] In this embodiment, the dilator 200 further includes a guide tube 220 and an inflation unit 230. The elastic balloon 210 and the inflation unit 230 are respectively disposed at both ends of the guide tube 220. The inflation unit 230 is used to inflate the elastic balloon 210. The inflation unit 230 includes a valve that can be connected to an external gas source.

[0068] The flusher 300 includes an axially extending flushing tube 310, one end of which is provided with a first liquid inlet and outlet 311, and the other end of the flushing tube 310 is provided with a second liquid inlet and outlet 312 on the side wall. An elastic rubber plug 320 is provided on the outer peripheral surface of the flushing tube 310 between the first liquid inlet and outlet 311 and the second liquid inlet and outlet 312, and the outer diameter of the elastic rubber plug 320 is not less than the inner diameter of the hollow channel 1111. The sheath 110 of the puncture device 100 also includes an operating joint 112, which is connected to the operating end of the hollow channel 1111, and a flushing joint 130 is provided on the side wall of the operating joint 112, which is connected to the first channel 1122 in the operating joint 112. When the flusher 300 and the sheath 110 are assembled, the first channel 1122 is connected to the second liquid inlet and outlet 312 and is circumferentially sealed. The outer diameter of the elastic plug 320 is not less than the inner diameter of the hollow passage 1111, so that the elastic plug 320 isolates the peritoneal cavity from the outside world, so that a sealed space is formed in the peritoneal cavity, so that when the flusher 300 is used, a negative pressure can be formed in the peritoneal cavity, which is conducive to the absorption of liquid. During surgery, some tissue fragments, blood, tissue fluid, etc. will be produced in the peritoneal cavity, which will affect the doctor's surgical field of view and need to be cleaned. The flushing tube 310 of the flusher 300 is inserted into the patient's body through the hollow passage 1111 of the sheath 110, and the corresponding area is first flushed by the external flushing liquid of the flushing joint 130, and then sucked out, so that the tissue fragments, blood, and tissue fluid can be sucked out, thereby ensuring that the doctor can perform surgery better. In addition, the flusher 300 can also flush observation equipment such as endoscopes.

[0069] In some embodiments, the flushing tube 310 is a retractable structure, and the retractable connection position is inside the elastic rubber plug 320, and the elastic rubber plug 320 is also made into a retractable structure. The flushing tube 310 is made into a retractable structure to absorb liquids at different positions according to needs.

[0070] The puncture flushing suturing assembly also includes a suturing device 400, which includes a main body 410, the insertion end of the main body 410 has a rotating member 420 that can be unfolded outward, the outer peripheral surface of the main body 410 has a puncture groove 411 for inserting a suturing needle 500, and when the rotating member 420 is unfolded, the suturing needle 500 can be inserted into and pass through the puncture area on the rotating member 420 after passing through the puncture groove 411, and the main body 410 is configured to be inserted into the hollow channel 1111 and the rotating member 420 can extend out of the puncture end of the hollow channel 1111. In order to make the patient recover better, the doctor needs to suture not only the external skin incision after the operation, but also the fascia in the body. After the operation is completed, the suture device 400 is inserted into the patient's body through the hollow channel 1111 of the sheath 110, and the rotating member 420 is unfolded after insertion. The thread ends of the suture thread are sent into the inner side of the fascia on both sides of the skin incision after the suture needle 500 passes through the puncture groove 411, and then the rotating member 420 is reset and the sheath 110 and the suture device 400 are pulled out of the hollow channel 1111. At this time, the thread ends of the suture thread are pulled out of the skin incision under the drive of the suture device 400, and the suture thread will be pulled out of the puncture groove 411 and enter the human body. The fascia is sutured by cross-knotting the thread ends of the suture thread.

[0071] In the present application, the puncture, flushing and suturing assembly designs the puncture device 100 into a detachable sheath 110 and a puncture sheath needle 120. After puncturing the surgical site of the patient, the puncture sheath needle 120 is removed, and the hollow channel 1111 of the sheath 110 is used as an entry and exit channel for the dilator 200, the flusher 300, the stapler 400, the endoscope and surgical instruments, thereby avoiding repeated insertion of different instruments into the patient's skin incision during the operation, reducing the risk of postoperative complications such as wound bleeding and incisional hernia, and also saving the doctor the step of observing and adjusting the position of the instrument after inserting different instruments into the human body, thereby shortening the operation time and reducing the occurrence of uncontrollable surgical risks.

[0072] In this embodiment, a cavity 1121 is provided in the operating joint 112, which is coaxial with the hollow channel 1111. The inner diameter of the cavity 1121 is not less than the inner diameter of the hollow channel 1111. An openable and closable seal 113 is provided at one end of the cavity 1121 away from the hollow channel 1111. The first channel 1122 is connected to the cavity 1121. With the above structure, the sealing member 113 seals the channel connecting the hollow channel 1111 with the outside, so that the external negative pressure mechanism can absorb the smoke generated when the doctor cuts the tissue in the extra-abdominal cavity with the electric knife through the first channel 1122 to avoid affecting the surgical field of view; it can also absorb larger tissue fragments.

[0073] Specifically, in this embodiment, the operating joint 112 has a square structure, and a cylindrical cavity 1121 is provided inside. One end of the cylindrical cavity 1121 is provided with an internal thread, and the other end is provided with a seal that can be opened and closed. The outer cylinder wall of the operating end of the puncture tube 111 is provided with an external thread, and the puncture tube 111 and the operating joint 112 are fixed by threaded connection. The side end of the operating joint 112 is provided with a first channel 1122, and the first channel 1122 is connected to the cavity 1121.

[0074] The flushing connector 130 includes a first connecting valve 131 and a second connecting valve 132. The first connecting valve 131 and the second connecting valve 132 are both detachably connected to the operating connector 112 via a connecting portion 133. The first connecting valve 131 is connected to the flushing liquid delivery pipe and is used to deliver flushing liquid to the flushing pipe 310. The second connecting valve 132 is connected to the return liquid pipe and is used to draw liquid from the extra-abdominal cavity.

[0075] In this embodiment, a limiting portion 122 is provided at one end of the puncture sheath needle 120 away from the needle tip, and the limiting portion 122 is used to cooperate with the operation joint 112 to limit the depth of the puncture sheath needle 120 inserted into the hollow channel 1111. By providing the limiting portion 122, a suitable insertion depth can be selected according to the patient's body shape, avoiding accidental injuries caused by excessive puncture or the need for a second puncture due to failure to puncture in place at one time, which affects the progress of the operation.

[0076] The limiting portion 122 of the puncture sheath needle 120 can be fixedly connected to the needle body 121 of the puncture sheath needle 120. During surgery, puncture sheath needles 120 of different lengths can be selected according to the patient's obesity level; the limiting portion 122 of the puncture sheath needle 120 can also be movable and adjustable to adjust the length of the needle body 121 as needed.

[0077] In this embodiment, the elastic rubber plug 320 is a spindle structure. The elastic rubber plug 320 is designed as a spindle structure so that the flushing tube 310 can be stably positioned in the hollow channel 1111 and can be easily inserted or pulled out, thereby avoiding the flushing tube 310 from causing a large pulling on the skin incision when being inserted or pulled out.

[0078] In other embodiments, the elastic rubber plug 320 may also be made into a conical structure or a cylindrical structure, and may be sealed by a circumferential interference fit with the inner wall of the hollow channel 1111, which is not specifically limited here.

[0079] In this embodiment, the elastic rubber plug 320 is made of silicone. Of course, the elastic rubber plug 320 can also be made of other elastic materials that meet relevant medical standards.

[0080] In this embodiment, the puncture groove 411 includes a first puncture groove and a second puncture groove, and the first puncture groove and the second puncture groove are centrally symmetrically arranged. The two puncture grooves facilitate the insertion of the suture needle 500 to insert the two ends of the suture thread into the inner side of the fascia on both sides of the skin incision.

[0081] The angle formed by the axis of the first puncture groove and the second puncture groove and the central axis of the main body 410 of the suture device 400 is 10°-30°. The above angle setting can, on the one hand, prevent the needle of the suture needle 500 from deviating too much from the sheath 110 after insertion, causing the needle of the suture needle 500 to cause accidental damage to the human body, and on the other hand, make the main body size of the suture device 400 smaller, which is convenient for entering and exiting the hollow channel 1111. Specifically, the angle formed by the axis of the puncture groove 411 and the central axis of the main body 410 can be related to the length of the main body 410. This is because the length of the main body 410 of the suture device 400 used by different patients may also be different. In order to avoid the suture needle 500 from causing accidental damage to the patient during insertion, it is necessary to select a suture device 400 of appropriate length according to the patient's body shape.

[0082] Silicone is installed in the puncture area of ​​the rotating member 420. The silicone allows the suture needle 500 to insert the thread end of the suture into the inner side of the fascia and then pull it out. The thread end of the suture can be clamped by the elasticity of the silicone itself, so that the thread end of the suture is retained on the inner side of the fascia, and at the same time, the thread ends of the suture are pulled out from the skin incision when the puncture suture sheath is pulled out.

[0083] A linkage mechanism 430 is disposed in the main body 410 of the suture device 400 . The linkage mechanism 430 is connected to the rotating member 420 . The linkage mechanism 430 is used to control the expansion and resetting of the rotating member 420 .

[0084] See also Figure 9-10 Specifically, the linkage mechanism 430 includes a pull rod 431, which can move along the axis direction of the main body 410 in the main body 410, one end of the pull rod 431 extends out of the main body 410 and is provided with a pull ring 432, and the other end of the pull rod 431 is pivotally connected to the rotating member 420. The rotating member 420 includes a puncture area 421 and a pivoting area 422 located on one side of the puncture area 421, and the pivoting area 422 is provided with a C-shaped hole 4221. The end of the insertion end of the main body 410 is provided with a U-shaped groove, and a limiting column is installed on the inner side wall of the U-shaped groove. The limiting column is inserted into the C-shaped hole 4221 and can slide relative to the C-shaped hole 4221. The pull rod 431 is pulled by the pull ring 432 to move along the axis of the main body 410 . When the pull rod 431 is pulled toward the insertion end away from the main body 410 , the rotating member 420 will expand outward. After the pull rod 431 is reset, the rotating member 420 will also be reset.

A puncture groove 611 is provided on the outer surface of the main body 610, and the puncture groove 611 is used for the suture needle 500 to pass through. When the rotating member 620 is rotated to the preset position, the suture needle 500 can be inserted into and pass through the puncture area 621 after passing through the puncture groove 611. The puncture area 621 is configured to retain the suture thread on the suture needle 500 at the puncture area 621 after the suture needle 500 passes through the puncture area 621.

[0087] After the operation is completed, the rotating member 620 is unfolded, and the thread ends of the suture thread are sent into the inner side of the fascia on both sides of the skin incision after the suture needle 500 passes through the puncture groove 611. Then the rotating member 620 is reset and the suture device 600 is pulled out. At this time, the thread ends of the suture thread are pulled out from the skin incision under the drive of the suture device 600. The suture thread will be detached from the puncture groove 611 and enter the human body under the pulling of the thread ends at both ends. The fascia is sutured by cross-knotting the thread ends of the suture thread.

[0088] In this embodiment, there are two notches 612, which are symmetrically arranged, and a rotating member 620 is installed in each notch 612. By providing two rotating members 620, the ends of the suture thread can be pierced into the inner side of the fascia on both sides of the skin incision without rotating the main body 610 during suturing, thereby avoiding accidental injuries caused by the rotation of the suture device 600.

[0089] In some other embodiments, only one notch 612 and a corresponding rotating member 620 may be provided. When suturing, the thread end of the suture may be first fed into the inner side of the fascia, and then the suture device 600 may be rotated 180 degrees, and then the other end of the suture may be fed into the inner side of the fascia, so that suturing can also be performed. Of course, in some embodiments, other reasonable number of rotating members 620 may be provided, and when suturing, multiple sutures may be used to better suture the inside of the incision.

[0090] In this embodiment, the puncture groove 611 includes a first puncture groove and a second puncture groove, and the first puncture groove and the second puncture groove are centrally symmetrically arranged. The two puncture grooves 611 facilitate the insertion of the suture needle 500 to insert the two ends of the suture thread into the inner side of the fascia on both sides of the skin incision.

[0091] The angle formed by the axis of the first puncture groove and the second puncture groove and the central axis of the main body 610 of the stapler 600 is 10°-30°. The axis of the puncture groove 611 and the central axis of the main body 610 are set at the above angle to prevent the needle of the suture needle from deviating too much from the main body 610 after insertion, causing the needle of the suture needle 500 to cause accidental damage to the human body. Specifically, the angle formed by the axis of the puncture groove 611 and the central axis of the main body 610 can be related to the length of the main body 610. This is because the length of the main body 610 used by different patients may also be different. In order to avoid accidental damage to the patient when the suture needle 500 is inserted, it is necessary to select a stapler 600 of appropriate length according to the patient's body shape.

[0092] like Figure 11-16 As shown, in this embodiment, the inner wall surface of the cavity 613 in the main body 610 is provided with a guide groove 614 along the axial direction of the main body 610, the upper end of the guide groove 614 extends to the upper end of the main body 610, and the lower end of the guide groove 614 extends to the notch 612; a linkage assembly is provided in the guide groove 614, and the linkage assembly is configured to slide in the guide groove 614, and the linkage assembly controls the rotation of the rotating member 620 to make it unfold and reset when sliding. By adopting the above structure, the rotating member 620 can be unfolded when fascia suturing is required, so that the thread ends of the suture thread on the suture needle 500 are retained on the inner side of the fascia of the abdominal cavity, so that the thread ends of the suture thread at both ends can be pulled out from the skin incision when the suture device 600 is pulled out.

[0093] Specifically, Figure 11-16 As shown, the pivoting area 622 of the rotating member 620 is installed in the notch 612 through the rotating shaft 623, and the pivoting area 622 of the rotating member 620 is provided with a C-shaped hole 6221, and the C-shaped hole 6221 opens toward the outside of the main body 610. The linkage assembly includes a sliding shaft 630, and the sliding shaft 630 passes through the C-shaped hole 6221. The two ends of the sliding shaft 630 are slidably matched with the two opposite side walls of the guide groove 614. The sliding shaft 630 slides between the first position and the second position, as shown in FIG. Fig.13 As shown, in the first position, the sliding shaft 630 is located at one end of the C-shaped hole 6221 away from the piercing area 621 of the rotating member 620, and the rotating member 620 is located inside the notch 612; Fig.15As shown, in the second position, the sliding shaft 630 is located at one end of the C-shaped hole 6221 close to the puncture area 621 of the rotating member 620, and the puncture area 621 of the rotating member 620 is located outside the main body 610. Through the above structure, the rotating member 620 rotates in a preset rotation direction to perform fascia suturing.

[0094] like Figure 11-16 As shown, the linkage assembly further includes a control rod 640, which is disposed in the guide groove 614. One end of the control rod 640 is connected to the sliding shaft 630 to drive the sliding shaft 630 to slide between the first position and the second position.

[0095] The main body 610 of the stapler 600 may also be provided with a mechanism (not shown in the figure) for locking and limiting the control rod 640. For example, after the control rod 640 controls the sliding shaft 630 to move to the first position or the second position, the control rod 640 is locked and limited so that the sliding shaft 630 remains in the corresponding position, preventing the sliding shaft 630 from moving again and affecting the doctor's surgery.

[0096] The locking and limiting mechanism can be a structure that locks and limits the control rod 640 through threaded matching. For example, the control rod 640 has an external thread, and the main body 610 has a threaded hole that matches the external thread. The control rod 640 cooperates with the threaded hole, and the control rod 640 is rotated to make it move axially along the guide groove 614. The locking and limiting mechanism can also lock and limit the control rod 640 through a card-connected structure. For example, two card slots are arranged on the control rod 640 at a certain distance. The upper end surface of the main body 610 has a movable card block, which can be inserted into and disengaged from the card slot. When the control rod 640 needs to be moved, the card block disengages from the card slot, and the control rod 640 moves freely. When the control rod 640 controls the sliding shaft 630 to move to the first position, the card block can be inserted into the lower card slot, so that the rotating member 620 is located inside the notch 612 and remains stationary. When the control rod 640 controls the sliding shaft 630 to move to the second position, the card block can be inserted into the upper card slot, so that the movable end of the rotating member 620 is located at a preset position outside the main body 610 and remains stationary.

[0097] In some other embodiments, the rotating member 620 may be controlled to rotate and reset by other conventional mechanical structures, which will not be described in detail here.

[0098] In this embodiment, the outer surface of the rotating member 620 is coplanar with the outer surface of the main body 610. Through the above structure, the outer surface of the rotating member 620 is coplanar with the outer surface of the main body 610, which can prevent the outer surface of the rotating member 620 from protruding from the outer surface of the main body 610, resulting in secondary damage to the skin incision during puncture.

[0099] The puncture area 621 is installed with silicone, so that when the suture needle 500 sends the thread end of the suture into the inner side of the fascia and then pulls it out, the thread end of the suture can be clamped by the elasticity of the silicone itself, so that the thread end of the suture is retained on the inner side of the fascia. At the same time, when the suture device 600 is pulled out, the thread ends of the suture are pulled out from the skin incision.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
