Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a hernia sac adhesive applicator. Background Art

[0002] The inguinal region is a triangular area at the junction of the lower abdominal wall and the thigh. Inguinal hernia refers to a mass formed by the protrusion of abdominal viscera through the defect in the inguinal region to the body surface, commonly known as "hernia". Indirect inguinal hernia is a common disease in children, and high ligation of the hernia sac is an effective treatment method.

[0003] With the development of medicine, laparoscopic high ligation of the hernia sac is adopted in the operation of indirect inguinal hernia in many hospitals. In the prior art, laparoscopic surgeries for inguinal hernia repair using methods such as high ligation and patch repair have been widely used, and the derived laparoscopic suture instruments and patch clamps are widely applied. For example, CN2822532Y relates to a repair suture needle for laparoscopic minimally invasive surgery. The surgical repair suture needle mainly includes a needle core, a needle sheath and a needle fork. The needle core is a solid core structure, the needle sheath is a hollow structure, the needle core can be sleeved into the needle sheath, the top of the needle core is sleeved into the top of the needle sheath and is flush with or slightly protrudes from the opening edge thereof. The needle fork is a solid core structure, a fork branch is opened at its top end, the needle fork is longer than the needle sheath and can be sleeved into the needle sheath, and the fork branch passes through the opening at the top end of the needle sheath. Or, taking the device disclosed in CN210158713U for laparoscopic 3D hernia patch surgery as an example. The device includes a base, a suspension rod is fixedly installed at the lower end of the base, the suspension rod is movably connected with a first connecting rod, a second connecting rod and a third connecting rod, a hanging bottle device is fixedly connected to one end of the third connecting rod, a first movable rod is movably connected to the lower end of the left part of the second connecting rod, and a camera device is fixedly connected to the upper end of the left part of the second connecting rod. A second movable rod is movably connected to the lower end of the right part of the third connecting rod, one ends of the first movable rod and the second movable rod are both movably connected with a movable frame, and a shadowless lamp is movably connected to the movable frame.

[0004] However, in the prior art, there is a risk of damaging the spermatic cord of male patients or the round ligament of the uterus of female patients in the open high ligation of the hernia sac or laparoscopic high ligation of the hernia sac (i.e., separating the hernia sac and surgically suturing the high circumferential ligation of the hernia sac through an abdominal wall puncture suture device under laparoscopy), especially in female patients, the round ligament of the uterus is closely adhered to the hernia sac, and the separation of the hernia sac is more difficult, resulting in the severance of the round ligament of the uterus or the ligation of the round ligament of the uterus together with the hernia sac when ligating the hernia sac at a high position during the operation.

[0005] Based on this, the present application designs a device for adhesively closing the hernial sac, namely a high-position hernial sac adhesive applicator for inguinal hernia. This device further optimizes the practicability and convenience of laparoscopic high ligation of the hernial sac during the process of adhesively closing the hernial sac, enabling the adhesive applicator to quickly adhesively close the hernial sac without affecting the hernial contents and intra-abdominal organs, without the need to separate the hernial sac, and without causing damage to the spermatic cord in male patients or the round ligament of the uterus in female patients when achieving the effect of high ligation during hernial sac adhesion.

[0006] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, although the applicant studied a large number of documents and patents when making this utility model, due to space limitations, all details and content are not listed in detail. However, this does not mean that this utility model does not possess the features of these prior arts. On the contrary, this utility model already possesses all the features of the prior arts, and the applicant reserves the right to add relevant prior arts in the background art. Summary of the Utility Model

[0007] After separating the hernia tissue in the inguinal region in the prior art, it is usually necessary to place a relatively large tissue patch at the protruding part of the hernia to isolate the hernial sac from the outer hernial cavity and prevent the recurrence of the hernia. For example, CN113081380A discloses a laparoscopic hernia patch glue applicator. During laparoscopic total extraperitoneal hernia repair, the hook at the head of the instrument can conveniently hook the mesh hole of the patch, move the patch to the position where it needs to be placed, and then put the biological glue rod for fixing the patch into the barrel cavity of this instrument, and use the biological glue to fix the patch on the intra-abdominal tissue. However, this technical solution focuses on the placement and fixation of the patch, and there is a risk of damaging the surrounding tissues when using this applicator to place the patch, which is the treatment method that this utility model aims to avoid. In addition, during the process of placing the patch in a narrow space, it is necessary to ensure the accuracy of the patch placement position so that it can correspond to the glue application position, so as to effectively isolate the hernial sac from the outer hernial cavity. This method requires different operating devices to complete the glue application and the patch placement process, which significantly increases the operation steps and operation difficulty, and at the same time cannot avoid damaging the surrounding tissues during this operation process.

[0008] The present application provides a hernial sac adhesive applicator, and the hernial sac adhesive applicator includes a sheath tube.

[0009] The hernia sac adhesive device further includes: a hollow guide rod that can pass through the sheath tube and has a diameter smaller than that of the sheath tube. The distal end of the hollow guide rod is connected to a support assembly with a glue-brush on its surface. The proximal end of the hollow guide rod capable of adhering the hernia sac is provided with a first conversion cap that can be hermetically connected to a pressure regulating device capable of sucking the gas inside the hernia sac to make the hernia sac enter a negative pressure state. Compared with the above-mentioned prior art, the hernia sac adhesive device in the present invention is provided with a hollow guide rod capable of adhering the hernia sac, and a support assembly with a glue-brush is arranged on the hollow guide rod. This hernia sac adhesive device does not need to block the hernia sac by the way of additionally placing a patch. Based on the above different technical features, the technical problems to be solved by the present invention may include: how to prevent accidental damage to surrounding tissues while ensuring the effectiveness of hernia sac adhesion. Specifically, traditional open high ligation of the hernia sac or laparoscopic high ligation of the hernia sac may cause damage to the spermatic cord or round ligament of the uterus. The present invention uses the method of adhesion instead of ligation, thus omitting operation steps such as patch placement, and does not need to block the hernia sac by ligation, thereby avoiding the risk of damage to surrounding tissues in these operation steps and improving the safety of the operation. In addition, the present invention integrates multiple functions (such as gas suction, negative pressure establishment, adhesive application, etc.) into a single device, improving the efficiency of the operation, shortening the operation time, and using an airbag to block the hernia ring and establish a negative pressure environment, which helps to more effectively adhere the hernia sac, thereby reducing the possibility of hernia recurrence.

[0010] According to a preferred embodiment, the support assembly is arranged as an annular structure with a larger arc at the distal end than at the proximal end.

[0011] According to a preferred embodiment, a first holding handle is arranged in a region of the hollow guide rod near the proximal end, and the first holding handle is arranged in a parallel plane with the support assembly. Compared with the above-mentioned prior art, the first holding handle on the hollow guide rod of the present invention and the support assembly are in the same plane. Based on the above different technical features, the technical problems to be solved by the present invention may include: how to realize the positioning of the application position of the support assembly. Specifically, the relative positions of the support assembly and the first holding handle of the present invention are fixed. When the support assembly enters the human body, by observing the rotation direction and position of the first holding handle, medical staff can timely know the rotation orientation and the current angle of the support assembly in the human body, and then realize the accurate positioning of applying medical glue to the inner membrane of the hernia sac through the support assembly.

[0012] According to a preferred embodiment, the hernia sac adhesive device further includes: a catheter with one end communicating with an airbag arranged at the distal end of the sheath tube to be able to inflate the airbag entering the body outside the body. The side wall of the catheter is attached to the side wall of the sheath tube and forms an extension direction same as the extension direction of the sheath tube.

[0013] According to a preferred embodiment, the airbag is arranged as an annular airbag surrounding the distal end of the sheath tube. By injecting gas through the fourth conversion cap, the airbag can be inflated to seal the hernia ring.

[0014] According to a preferred embodiment, the hernia sac adhesive applicator is further provided with a sleeve sleeving the hollow guide rod, wherein the diameter of the sleeve is smaller than the diameter of the sheath tube.

[0015] According to a preferred embodiment, the glue-brushing brush part is arranged at the distal end of the support assembly.

[0016] According to a preferred embodiment, the proximal end of the catheter is provided with a fourth conversion cap capable of being hermetically connected to a pneumatic regulation device for injecting / aspirating gas into / from the airbag.

[0017] According to a preferred embodiment, the inner side of the first conversion cap is provided with a thread matching the proximal end of the hollow guide rod so as to be separable from the hollow guide rod when the hollow guide rod enters from the distal end of the sleeve.

[0018] According to a preferred embodiment, the support assembly is arranged as a water-drop-shaped support ring.

[0019] Advantages of the technical solution:

[0020] 1. The hernia sac is a tissue composed of an inelastic abdominal cavity inner membrane squeezed by the hernia content. Whether it is an open operation or a laparoscopic operation for pediatric inguinal hernia, the restoration of the position of the hernia content does not mean that the hernia content will not enter the hernia sac again through the hernia ring (i.e., the opening of the hernia sac facing the abdominal cavity), resulting in problems such as necrosis. Therefore, the clinical treatment of the hernia sac includes the reduction of the hernia content and the high ligation of the hernia sac. However, the above operations mean that when performing the high ligation of the hernia sac, since the hernia content (such as the small intestine) will peristalsis, there is a risk that the reduced hernia content will enter the hernia sac again, causing injury and leading to serious complications (such as intestinal fistula, bleeding, etc.). In this application, an annular airbag is arranged at the distal end of the sheath tube. When treating the hernia sac, the annular airbag can block the hernia ring to prevent the hernia content from re-entering the hernia sac, and the internal space of the sheath tube can provide an operating space for the hollow guide rod.

[0021] 2. Compared with the prior art which disposes the hernia sac by means of a patch or direct high ligation, the present application is set in an adhesive form instead of a separation and ligation form, thus avoiding the risk of damage to the spermatic cord of male patients and the round ligament of the uterus of female patients when using an abdominal wall puncture suture device and ligation thread during high ligation. For example, when performing an open high ligation of the hernia sac or laparoscopic high ligation of the hernia sac on a minor inguinal hernia patient, the possibility of damaging the spermatic cord of male patients or the round ligament of the uterus of female patients is relatively high. Especially for female patients, the round ligament of the uterus is closely adhered to the hernia sac, making it more difficult to separate the hernia sac, resulting in the severance of the round ligament of the uterus or the ligation of the round ligament of the uterus together with the hernia sac during high ligation of the hernia sac during the operation. The present application is set to apply medical glue to the inner membrane of the hernia sac through a support assembly, and through the action of negative pressure, the hernia sac is self-reduced until the inner membranes adhere to each other. This operation does not require additional separation of the spermatic cord and the round ligament of the uterus that are attached to the hernia sac, and also avoids the problem of damage to the spermatic cord and the round ligament of the uterus adhered to the outside of the hernia sac during the separation and ligation process.

Detailed implementation mode

[0032] The following is a detailed description with reference to the accompanying drawings.

[0033] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, terms such as "configured as", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. The meaning of "several" is two or more unless otherwise clearly and specifically limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In this application, the proximal end refers to the end of the device close to the operator, and the distal end refers to the end of the device far from the operator.

[0034] This application provides a hernia sac adhesive. This application also provides a high-position adhesive for the hernia sac of inguinal hernia. As Figure 2 shown, the hernia sac adhesive of this application includes a hollow guide rod 100, a sheath tube 200, and a sleeve 300, all of which are designed as hollow cylinders. Among them, the inner diameter of the sheath tube 200 is greater than the outer diameter of the sleeve 300, and the inner diameter of the sleeve 300 is greater than the outer diameter of the hollow guide rod 100, so that the three can be detachably combined into a whole by means of mutual sleeving (as Figure 1 shown).

[0035] Preferably, as Figure 3 shown, a support assembly 130 for adhering to the hernia sac is provided at the distal end of the hollow guide rod 100. As Figure 2 shown, a first conversion cap 110 is provided at the proximal end of the hollow guide rod 100, and a pneumatic pressure regulating device can be hermetically connected to the first conversion cap 110 to make the hernia sac enter a negative pressure state by sucking the gas inside the hernia sac. Preferably, in this application, as Figure 2The shown first conversion cap 110, second conversion cap 220, third conversion cap 310, and fourth conversion cap 410 are all general-purpose conversion caps used in laparoscopic instruments in the prior art. Among them, both the first conversion cap 110 and the fourth conversion cap 410 can be connected to a pneumatic regulation device (such as a syringe) with the function of injecting / aspirating gas, while the second conversion cap 220 and the third conversion cap 310 can cooperate with each other and be detachably connected into a whole. Preferably, these four conversion caps all have the characteristic of detachable installation, which enables these conversion caps to meet the installation and removal requirements at different usage stages of the hernia sac adhesive applicator.

[0036] Preferably, as Figure 1 shown, the support assembly 130 at the distal end of the hollow guide rod 100 is set as an elastic annular support ring in the shape of a water droplet, and its relatively flat distal end can fit the hernia sac. The support assembly 130 with this structure can support the hernia sac in the coronal position when inserted into the hernia sac, which is beneficial to the flattening and fitting of the hernia sac in the coronal position. Preferably, when the hollow guide rod 100 makes a pulling action from the distal end to the proximal end relative to the sleeve 300, the support assembly 130 elastically retracts under the restriction of the distal end opening of the sleeve 300, so that its shape changes from flat and wide to slender. At this time, the outer dimension of the support assembly 130 matches the inner diameter of the sleeve 300, enabling the support assembly 130 to move in the sheath tube 200 without contacting the inner wall of the sheath tube 200.

[0037] Preferably, as Figure 2 shown, a second conversion cap 220 is configured at the proximal opening of the sheath tube 200, and the second conversion cap 220 can be detachably connected to the barrel of the sheath tube 200 in a plug-in or threaded connection manner. The sheath tube 200 is also configured with a second holding handle 210 connected to the outer wall of its proximal end for stabilizing the sheath tube 200, enabling medical staff to accurately control the position of the sheath tube 200 by grasping the second holding handle 210.

[0038] Preferably, as Figure 3 shown, the support assembly 130 may include a flexible support ring 131 and an adhesive brush 132 disposed on its surface. The adhesive brush 132 can dip medical glue so that the support assembly 130 can adhere to the hernia sac while supporting it after entering the hernia sac. The flexible support ring 131 is a pipe with a lumen made of a flexible material (such as medical plastic material), and a plurality of through holes are arranged at certain intervals on the side wall of the pipe. The through holes are preferably adjacent to the adhesive brush 132. As Figure 7As shown, both ends of the flexible support ring 131 pass through the wall of the hollow guide rod 100 and are respectively joined to the distal end of the diversion tube 140 disposed inside the hollow guide rod 100, thereby forming a Y-shaped structure at the opening position adjacent to the distal end within the hollow guide rod 100. The diversion tube 140 can extend along its length direction inside the hollow guide rod 100, and the proximal end of the diversion tube 140 can be connected to the catheter opening 150 provided on the proximal side wall of the hollow guide rod 100 (as Figure 8 shown). When it is necessary to apply medical glue to the hernia sac, medical staff can pour medical glue into the lumen of the flexible support ring 131 communicating with the diversion tube 140 from the catheter opening 150 communicating with the diversion tube 140. The flexible support ring 131 abuts against the inner wall of the hernia sac. The glue-applying brush 132 can absorb the medical glue oozing out from several through holes opened on the side wall of the flexible support ring 131, and apply the medical glue to the hernia sac by means of the rotation of the flexible support ring 131 within the hernia sac.

[0039] According to a preferred embodiment, the support assembly 130 can also be arranged as an application block 160. Preferably, the application block 160 can be a medical sponge. As Figure 4 shown, the application block 160 is arranged in a cylindrical structure or a tubular structure. The application block 160 is preferably sleeved on the distal end of the hollow guide rod 100, and at least part of its structure can be connected to the diversion tube 140 within the hollow guide rod 100. Through the catheter opening 150 provided at the distal end of the hollow guide rod 100, medical staff can pour medical glue from the proximal end of the hollow guide rod 100 to enable the application block 160 to absorb the medical glue. Medical staff control the application block 160 to apply the inner wall of the hernia sac. When it is necessary to aspirate the gas in the hernia sac, a new hollow guide rod 100 can be replaced.

[0040] According to a preferred embodiment, as Figure 2 shown, a first holding handle 120 is provided in the area of the hollow guide rod 100 close to the proximal end, wherein the first holding handle 120 is arranged in a manner parallel to the plane where the support assembly 130 is located. The relative positions of the support assembly 130 and the first holding handle 120 are fixed. When the support assembly 130 enters the human body, by observing the rotation direction and position of the first holding handle 120, medical staff can timely know the rotation orientation and the current angle of the support assembly 130 within the human body.

[0041] According to a preferred embodiment, as Figure 1 、 Figure 2As shown, the hernia sac adhesive device further includes a catheter 400 for inflating the airbag 230 provided at the distal end of the sheath tube 200. The side wall of the catheter 400 is attached to the side wall of the sheath tube 200 and forms an extension direction same as that of the sheath tube 200. One end of the catheter 400 is connected to the airbag 230, and the other end is provided with a fourth conversion cap 410. The fourth conversion cap 410 can be connected to a pneumatic regulation device (such as a syringe) with the function of injecting / aspirating gas, so as to facilitate controlling the inflation and deflation of the airbag 230. Preferably, the airbag 230 is made of anti-rejection silicone material. Since the terminal part at the distal end of the sheath tube 200 needs to extend into the hernia sac, in order to ensure that the airbag 230 can correctly block the neck (hernia ring) of the hernia sac, the airbag 230 is provided at the terminal part at the distal end of the sheath tube 200.

[0042] Preferably, the third conversion cap 310 of the hernia sac adhesive device of the present utility model is detachably installed at the proximal end of the sleeve 300 only when in use, and the second conversion cap 220 is detachably installed at the proximal end of the sheath tube 200. During the socket installation, the proximal end of the sleeve 300 is inserted into the sheath tube 200 through the distal end of the sheath tube 200. The proximal end of the sleeve 300 can finally pass through the proximal end of the sheath tube 200, and then the third conversion cap 310 and the second conversion cap 220 are respectively installed on the sleeve 300 and the sheath tube 200. Arranging the installation process of the conversion cap after the sheath tube 200 and the sleeve 300 are socketed can enable the sleeve 300 to pass through smoothly and avoid the third conversion cap 310 installed in advance from affecting the installation process of the sleeve 300.

[0043] Preferably, the gap between the third conversion cap 310 and the second conversion cap 220 can be reduced by means of snap connection or threaded connection, so as to improve the airtightness at the distal openings of the sleeve 300 and the sheath tube 200. This can not only maintain the tightness of the sheath tube 200 placed in the abdominal cavity, but also help to establish a negative pressure environment in the hernia sac, making the hernia sac fit more tightly under negative pressure.

[0044] Preferably, after the sheath tube 200 and the sleeve 300 are sleeved and the third conversion cap 310 and the second conversion cap 220 are connected to each other, the hollow guide rod 100 can also be inserted into the interior of the sleeve 300 in a manner of inserting from the proximal end to the distal end of the sleeve 300 on the premise that the first conversion cap 110 and the first holding handle 120 at the distal end are removed, and after the insertion is completed, the first conversion cap 110 and the first holding handle 120 are reinstalled. Although there is a possibility that the sleeve 300 leaks air into the hernia sac due to the distal end of the sleeve 300 extending into the hernia sac, based on the high-power operation of the air pressure regulating device, the amount of gas flow generated by the tiny gap between the sleeve 300 and the hollow guide rod 100 is not sufficient to affect the establishment of the negative pressure state of the hernia sac. More preferably, the third conversion cap 310 at the distal end of the sleeve 300 can also be configured with a sealing ring to prevent air flow from entering the interior of the hernia sac through the gap between the sleeve 300 (especially the third conversion cap 310) and the hollow guide rod 100. The sealing ring can be configured as a rubber hoop with elastic contraction characteristics, which can be fixedly arranged on the inner surface of the third conversion cap 310, and its inner diameter without external force is slightly smaller than the outer diameter of the hollow guide rod 100. Thus, when the hollow guide rod 100 is inserted into the interior of the sleeve 300, it seals the gap by sleeving on the surface of the hollow guide rod 100.

[0045] According to a preferred embodiment, as Figure 2 , Figure 6 shown, the airbag 230 is set to be inflated by injecting gas through the fourth conversion cap 410, so that the airbag 230 expands to block the hernia ring, preventing the herniated contents that have been reduced from entering the hernia sac again. After the hernia ring is blocked, a sealed space is established inside the hernia sac. The neck of the hernia sac (hernia ring) is a circular or nearly circular opening with a rounded edge, and the present application provides an annular airbag 230. Preferably, the airbag 230 fits on the inner wall of the abdomen near the herniated contents side to close the hernia ring, separating the herniated contents from the hernia sac and preventing the herniated contents from entering the hernia sac.

[0046] According to a preferred embodiment, the sheath tube 200, the hollow guide rod 100, the support assembly 130 and the sleeve 300 are made of anti-rejection metal materials. The catheter 400 and the glue-coated brush 132 are made of anti-rejection silicone materials.

[0047] According to a preferred embodiment, the surfaces of the sheath tube 200, the hollow guide rod 100, the support assembly 130, the sleeve 300, the airbag 230, the catheter 400 and the glue-coated brush 132 are provided with anti-adhesive coatings.

[0048] The usage method of the device involved in the present application is as follows:

[0049] As Figure 2 shown, when the hernia sac adhesive of the present utility model is not in use, it can be stored separately in a sterile environment, that is, the sheath tube 200, the sleeve 300 and the hollow guide rod 100 are stored independently in a sterile environment.

[0050] When in need of use, medical staff can insert the proximal end of the sleeve 300 into the distal end of the sheath 200. The proximal end of the sleeve 300 can eventually pass through the proximal end of the sheath 200. Then, the third conversion cap 310 and the second conversion cap 220 are respectively installed on the sleeve 300 and the sheath 200. Then, medical staff can remove the first holding handle 120 and the first conversion cap 110 provided at the proximal end of the hollow guide rod 100, so that the hollow guide rod 100 can be inserted into the sleeve 300 through its proximal end. The proximal end of the hollow guide rod 100 extends out from the proximal end of the sleeve 300. As Figure 5 shown, medical staff successively install the removed first holding handle 120 and the first conversion cap 110 on the proximal end of the hollow guide rod 100. Insert a sheath core into the sheath 200, and insert the sheath 200 into the abdominal wall in the way of inserting a sheath card in laparoscopic surgery. Through the sheath 200, a 5mm laparoscope can be used to explore whether the abdominal cavity, the hernia sac and the hernia content are completely reduced. It is seen that the hernia content is completely reduced and there is no adhesion to the neck of the hernia sac. Medical staff connect a syringe to the catheter 400 through the fourth conversion cap 410, and inject gas into the annular airbag 230. The airbag 230 expands and blocks the neck of the hernia sac (hernia ring) to prevent the hernia content (abdominal organ hernia) from entering the hernia sac.

[0051] A 50mL syringe is connected to the first conversion cap 110 to create a negative pressure state in the hernia sac. A glue brush 132 applies medical glue. Medical staff insert the hollow guide rod 100 sleeved with the sleeve 300, which has been installed and on which the glue brush 132 has applied medical glue, into the proximal end of the sheath 200. Another medical staff moderately traction the spermatic cord. The medical staff in charge of this device controls the first holding handle 120 of the hollow guide rod 100 to rotate 180° clockwise or counterclockwise. Another medical staff controls the second holding handle 210 to keep the position of the sheath 200 unchanged. Immediately, another medical staff aspirates the gas in the hernia sac with a 50mL syringe connected to the first conversion cap 110 while maintaining the traction of the spermatic cord, so as to create a negative pressure environment inside the hernia sac. The medical staff in charge of this device controls the hollow guide rod 100 to rotate and withdraw from the human body while exiting the sheath 200 until the support assembly 130 completely retracts into the sheath 200.

[0052] Medical staff remove the 50mL syringe and release the connection between the third conversion cap 310 and the second conversion cap 220 to facilitate the withdrawal of the hollow guide rod 100 and the sleeve 300 together. Medical staff use a 5mm laparoscope to explore again that there is no damage to the abdominal organs. After the hernia sac is tightly glued, the gas in the annular airbag 230 is aspirated with a syringe through the fourth conversion cap 410, and then the sheath 200 is withdrawn.

[0053] The device of the present application can simplify the operation process of the hernia sac. Compared with the existing open hernia sac high ligation and laparoscopic hernia sac high ligation, the present application is designed to avoid the damage that may be caused to the spermatic cord or the round ligament of the uterus during the open inguinal hernia sac high ligation surgery or laparoscopic inguinal hernia sac high ligation surgery, improve the practicability and convenience of the hernia sac high ligation surgery technology for minor inguinal hernia patients, and is particularly important in reducing the injury of the hernia sac high ligation surgery technology for minor inguinal hernia patients. The overall convenience, efficiency and practicability of the device are relatively high.
