Description

Technical Field

[0001] The present invention belongs to the technical field of single-hole puncture devices, and in particular relates to a rotary single-hole puncture device with a soft rubber coating device. Background Art

[0002] With the advancement of laparoscopic equipment and technology, single-port laparoscopy has ushered in a scarless era of minimally invasive surgery. Since the surgical incision is small, the risk of postoperative wound infection is reduced, and it also has great advantages for patients with obesity, diabetes, and hypertension. Single-port laparoscopic surgery causes less postoperative pain, faster recovery, and shortens wound healing time. The function of existing single-port multi-channel puncture devices is to expand the wound on the abdominal wall to provide the necessary operating space for surgery. However, in actual use, the existing multi-channel puncture devices cannot guarantee the sealing effect of the internal joints, and there is a problem of diseased tissue contaminating the wound. In addition, the smoke generated during the surgical operation through the multi-channel puncture device cannot be discharged in time, affecting the surgeon's vision and the accuracy of the surgical operation.

[0003] In order to solve the shortcomings of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a multi-channel single-hole laparoscopic surgical puncture device [202210647525.9], which includes a laparoscopic surgical mechanism, the laparoscopic surgical mechanism includes a sleeve assembly, a puncture core, a carbon dioxide interface, a first cloth hole and a second cloth hole, the bottom of the sleeve assembly is clamped with the puncture core, the outer wall of the sleeve assembly is provided with two holes, the top of the sleeve assembly is fixedly connected to the second cloth hole at the position of the hole, the bottom of the top of the sleeve assembly away from the second cloth hole is provided with two holes, and the sleeve assembly is fixedly connected to the two first cloth holes through the holes.

[0004] The above solution solves the problem of smoke residue during surgery to a certain extent, but the solution still has many shortcomings, such as the inability to ensure the sealing of internal joints. Summary of the Invention

[0005] The purpose of the present invention is to address the above problems and provide a rotary single-hole trocar with a soft rubber coating device that has a reasonable design and effectively improves the sealing performance of the internal joint of the trocar.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a rotary single-hole puncture device with a soft rubber coating device, comprising a multi-channel sealing cover and an incision protection cover, wherein an upper sleeve and a lower sleeve are installed between the multi-channel sealing cover and the inner side of the incision protection cover, an adapter sleeve is provided between the upper and lower sleeves, and adapter grooves for inserting the upper and lower sleeves are provided at the upper and lower ends of the adapter sleeve, an extrusion mechanism is provided between the adapter groove and the upper and lower sleeves, and the adapter sleeve has a rubber coating mechanism opposite to the lower sleeve. The adapter sleeve connects the upper and lower sleeves, and the extrusion mechanism between them completely blocks the gap between them. The equipped rubber coating mechanism seals the outside of the adapter sleeve to ensure the sealing effect at the junction of the lower sleeve.

[0007] In the aforementioned rotary single-hole puncture device with a soft rubber coating, the extrusion mechanism includes an extrusion surface provided at the end of the adapter groove. The extrusion surface is arc-shaped and smoothly transitions into the adapter groove. An extrusion ring is provided at the ends of the upper and lower sleeves, which is pressed against the extrusion surface. The extrusion ring has a plurality of extrusion strips with triangular cross-sections, which are arranged equidistantly and circumferentially along the extrusion ring. An extrusion groove is provided on the inner side of the adapter groove, which is engaged with the extrusion strips in a one-to-one manner. A glue injection assembly is provided between the extrusion ring and the adapter groove. The extrusion mechanism provides a certain preload force to completely block the gap in the adapter groove, and cooperates with the glue injection assembly to fill the remaining gap.

[0008] In the aforementioned rotary single-hole puncture device with a soft rubber coating, the glue injection assembly includes a glue injection cavity disposed within the extrusion ring. The upper end of the extrusion ring is provided with a glue injection hole and a pressure relief hole communicating with the glue injection cavity. A circumferential glue injection groove is formed at the end of the extrusion ring and communicates with the glue injection cavity. A gap is left between the bottom of the adapter groove and the glue injection groove, and a plurality of injection capsules are provided on either side, symmetrically relative to the center of the extrusion ring. The glue injection assembly is sealed by external glue injection, which is locked after solidification.

[0009] In the aforementioned rotary single-hole trocar with a soft rubber coating, the extrusion surface is provided with a plurality of self-locking grooves arranged symmetrically with respect to the center. A self-locking portion, recessed toward the interior of the injection cavity, is provided on the side of the extrusion ring opposite the extrusion surface. The self-locking portion comprises self-locking blocks corresponding to the self-locking grooves. The self-locking portion is made of an elastic material and is integrally formed with the extrusion ring. After injection, the self-locking portion pushes the self-locking blocks out and engages with the self-locking grooves, thereby preventing them from falling out.

[0010] In the above-mentioned rotary single-hole puncture device with a soft rubber coating device, the rubber coating mechanism includes a ring-shaped rubber coating layer, the rubber coating layer has an integrally formed fixing layer and a bonding layer, the fixing layer and the adapter sleeve are bonded and fixed by an adhesive layer, the bonding layer is pressed and fixed to the lower sleeve, the fixing layer has a heat shrink layer that covers the outer side of the adapter sleeve, and a rubber sleeve is arranged between the rubber coating layer and the upper sleeve.

[0011] In the aforementioned rotary single-hole trocar with a soft rubber coating, a rotation mechanism is provided at the end of the upper housing near the adapter sleeve. This rotation mechanism is equipped with a locking mechanism, and a partition mechanism is provided between the upper and lower housings. The rotation mechanism adjusts the angle of the upper housing relative to the lower housing and is secured by the locking mechanism, thereby adjusting the surgical position. The partition mechanism covers the inner sides of the adapter sleeve and the lower housing, preventing internal protrusions from interfering with the entry and exit of surgical instruments.

[0012] In the aforementioned rotary single-hole puncture device with a soft rubber coating, the rotation mechanism includes a rotating ring disposed at the end of the upper sleeve, the rotating ring comprising two symmetrically arranged and mutually hinged sub-rings, a rotating sleeve rotatably mounted between the sub-rings, the rotating sleeve being connected to the upper sleeve, a rotating bar extending circumferentially disposed on the outer side of the rotating sleeve, a rotating groove slidably connected to the rotating bar formed on the inner side of the sub-rings, the rotating sleeve having a rotating cylinder extending to the outside of the rotating ring, the rotating cylinder having a rotating piece opposite the upper end of the rotating ring; a plug-in groove symmetrically disposed about the center of the rotating ring is formed on the outer side of the rotating ring, and a plug-in tooth correspondingly plugged into the plug-in groove is formed on the inner side of the sub-rings. The rotation mechanism provides the upper sleeve with a large degree of rotational freedom.

[0013] In the aforementioned rotary single-hole trocar with a flexible rubber coating, the locking mechanism includes a locking sleeve telescopically connected to the rotating cylinder. The outer surface of the locking sleeve is provided with anti-slip stripes, and a locking protrusion is disposed at the lower end of the locking sleeve. The locking protrusion extends through the rotating plate and faces the upper end of the rotating ring. The upper end of the rotating ring has a locking groove for the locking protrusion to be inserted. An elastic reset member is disposed between the locking sleeve and the rotating cylinder. The locking mechanism limits the relative angle between the multi-channel sealing cover and the adapter sleeve by sliding and plugging. The adapter sleeve is locked and fixed to the lower sleeve, thereby securing the upper and lower sleeves.

[0014] In the aforementioned rotary single-hole trocar with a flexible rubber coating, the partition mechanism includes a spacer sleeve connected to the lower end of the lower housing. The spacer sleeve is positioned between the upper housing and the inner side of the lower housing, with the other end of the spacer sleeve being pressed and secured to the upper housing. The partition mechanism blocks the internal passage of the trocar, and the spacer sleeve reinforces the lower housing, maintaining its cylindrical shape.

[0015] In the aforementioned rotary single-hole puncture device with a soft rubber coating device, a protective assembly is installed on the outside of the incision protective sleeve, the protective assembly including a protective cover, the protective cover being installed with a buffer ring through a movable mechanism, the buffer ring being coated with a protective layer of a flexible material, and an adaptive sealing assembly being provided between the buffer ring and the protective cover; the movable mechanism including a circular movable groove provided on the inside of the protective cover, a movable ring being provided at the upper end of the buffer ring and being slidably connected to the movable groove, and a movable bar being provided between the upper end of the movable ring and the inside of the movable groove to seal the movable groove; the adaptive sealing assembly including a sealing sleeve provided on the inside of the protective cover, a sealing gap being left between the sealing sleeve and the protective cover, the sealing gap being connected to the movable groove and being filled with a colloid, and a sealing membrane of an elastic material sealing the outlet of the sealing gap. When the protective cover is pressed down, the colloid is squeezed out of the sealing gap, and the colloid is coated in the sealing membrane, so that a slight negative pressure is formed inside the sealed protective cover, thereby improving the fixing effect and sealing performance of the adapter sleeve.

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 as well as Figure 7 As shown, a rotary single-hole puncture device with a soft rubber coating device includes a multi-channel sealing cover 11 and an incision protection cover 12. An upper sleeve 1 and a lower sleeve 2 are installed between the inner sides of the multi-channel sealing cover 11 and the incision protection cover 12. The upper sleeve 1 and the lower sleeve 2 are connected by an adapter sleeve 3. The upper and lower ends of the adapter sleeve 3 are provided with adapter grooves 31 for the upper sleeve 1 and the lower sleeve 2 to be inserted. The adapter groove 31 covers the ports of the upper sleeve 1 and the lower sleeve 2. The adapter sleeve 3 has a certain elasticity to achieve an interference fit. A squeezing mechanism 4 is provided between the adapter groove 31 and the upper sleeve 1 and the lower sleeve 2. The squeezing mechanism 4 applies a compressive force to the adapter groove 31. The adapter sleeve 3 has a rubber coating mechanism 5 opposite to the lower sleeve 2. The rubber coating mechanism 5 cooperates with the squeezing mechanism 4 to improve the sealing between the adapter sleeve 3 and the upper sleeve 1 and the lower sleeve 2, and to reduce the discomfort caused by the direct contact and pressure of the adapter sleeve 3 with the human body.

[0027] Specifically, existing rotary single-hole puncture devices mostly use a threaded connection to achieve the transition between the upper sleeve 1 and the lower sleeve 2. After the connection is completed, there is a large gap between them. If the gap is sealed by relying on its compression force, the small gap between them cannot be completely closed. The extrusion mechanism 4 includes an extrusion surface 41 provided at the end of the transfer groove 31. The extrusion surface 41 guides the upper sleeve 1 and the lower sleeve 2 into the transfer groove 31. The extrusion surface 41 is arc-shaped and smoothly transitions with the transfer groove 31. The internal width of the transfer groove 31 gradually decreases from the end toward the bottom.

[0028] from Figure 2It can be seen that an extrusion ring 42 that fits tightly against the extrusion surface 41 is provided at the end of the upper sleeve 1 and the lower sleeve 2. The adapter groove 31 is blocked by the extrusion ring 42. The extrusion ring 42 is made of a flexible material that can expand and deform under pressure. The extrusion ring 42 has a number of extrusion strips 43 with triangular cross-sections. The extrusion strips 43 are equidistantly arranged and surround the extrusion ring 42 circumference. A plurality of extrusion strips 43 are combined into a corrugated structure. An extrusion groove 44 that corresponds to the extrusion strip 43 on the inner side of the adapter groove 31 is provided. The extrusion groove 44 and the extrusion strip 43 are engaged with each other to ensure the fixed stability of the end of the extrusion ring 42. A glue injection component is provided between the extrusion ring 42 and the adapter groove 31. The expansion and deformation of the extrusion ring 42 is achieved by external glue injection. Under normal conditions, the extrusion ring 42 is in a contracted state.

[0029] In-depth, the glue injection component usually uses a one-time glue injection method to shape the extrusion ring 42. The glue injection component includes a glue injection cavity 32 set inside the extrusion ring 42. The hollow structure of the extrusion ring 42 is inflated to maintain the ring structure under normal conditions. When it is inserted into the adapter groove 31 and ensured to be completely fitted, the pressure is released and the glue is injected. The upper end of the extrusion ring 42 is provided with a glue injection hole 33 and a pressure relief hole 34 connected to the glue injection cavity 32. The glue is injected into the glue injection hole 33 through a syringe, and the pressure relief hole 34 remains open to discharge excess air inside. A glue injection groove 35 is opened at the end of the extrusion ring 42 along the circumference. The glue completely fills the glue injection groove 35. After solidification, the bottom of the extrusion ring 42 is pulled and fixed to the bottom of the adapter groove 31. The glue injection groove 35 is connected to the glue injection cavity 32. There is a gap between the bottom of the adapter groove 31 and the glue injection groove 35, and a number of injection capsules 36 are provided on both sides that are symmetrical relative to the center of the extrusion ring 42. When the injection capsule 36, the injection groove 35 and the injection cavity 32 are completely filled, some colloid overflows from the pressure relief hole 34 and is blocked. After the colloid solidifies, the upper sleeve 1 and the lower sleeve 2 are completely fixed to the adapter sleeve 3.

[0030] Furthermore, the extrusion surface 41 is pre-set with a plurality of self-locking grooves 45 arranged symmetrically with respect to the center. A self-locking portion 46 is arranged on the side of the extrusion ring 42 opposite the extrusion surface 41, which is recessed toward the interior of the glue injection cavity 32. The self-locking portion 46 has self-locking blocks 47 corresponding one-to-one with the self-locking grooves 45. The self-locking portion 46 is made of an elastic material and is integrally formed with the extrusion ring 42. Due to the elasticity of the extrusion ring 42, the self-locking portion 46 can expand when glue is injected into the glue injection cavity 32, causing the self-locking blocks 47 to be pushed out and inserted and fixed with the self-locking grooves 45.

[0031] like Figure 3As shown, in addition to arranging a flexible pad at the wound for protection, the rubber coating mechanism 5 on the outside of the adapter sleeve 3 can also be used for protection. The rubber coating mechanism 5 includes a ring-shaped rubber coating layer 51, which is usually made of silicone material. The rubber coating layer 51 has an integrally formed fixing layer 52 and a bonding layer 53. After the lower sleeve 2 and the adapter sleeve 3 are plugged and fixed, the bonding layer 53 is turned inward and fits with the lower sleeve 2. The fixing layer 52 and the adapter sleeve 3 are bonded and fixed by the adhesive layer, and the bonding layer 53 is pressed and fixed with the lower sleeve 2. The rubber coating layer 51 formed by the two avoids the oppressive feeling caused by direct contact between the adapter sleeve 3 and the human body. The fixing layer 52 has a heat shrink layer 54 that covers the outside of the adapter sleeve 3 to achieve one-time plastic sealing, and a rubber sleeve 55 is provided between the rubber coating layer 51 and the upper sleeve 1. A part of the rubber sleeve 55 is coated on the outside of the heat shrink layer 54, and the other part shrinks and fits with the upper sleeve 1.

[0032] In addition, during the actual surgical procedure, it is necessary to adjust the circumferential angle of the upper sleeve 1 in a timely manner to ensure that the surgical instruments are accurately positioned. The sliding gap retained by the conventional sliding and rotating structure is relatively short, and external pathogens can easily invade the gap of the upper sleeve 1 through the gap. The upper sleeve 1 in the present application is provided with a rotating mechanism 6 at one end close to the adapter sleeve 3 to ensure its normal activity structure. The rotating mechanism 6 is equipped with a locking mechanism 7 to achieve locking of the circumferential angle. A partition mechanism 8 is provided between the upper sleeve 1 and the lower sleeve 2 to separate the adapter sleeve 3. On the one hand, it prevents the adapter sleeve 3 from obstructing the movement of the surgical instruments. On the other hand, it forms a double-layer cylindrical structure with the lower sleeve 2, and the lower sleeve 2 can be reset in time after being torsionally deformed.

[0033] like Figure 4 As shown, the rotating mechanism 6 includes a rotating ring 61 arranged at the end of the upper sleeve 1. The rotating ring 61 is made of self-lubricating plastic material and has high wear resistance and rotation flexibility. The rotating ring 61 includes two symmetrically arranged and mutually hinged auxiliary ring bodies 62. The auxiliary ring bodies 62 connect the rotating rings 61 end to end through screws or snaps to achieve the closure of the rotating ring 61. A rotating sleeve 63 is rotatably installed between the auxiliary ring bodies 62. The rotating sleeve 63 is integrally formed with the rotating ring 61 of the upper sleeve 1. A rotating bar 64 extending in the circumferential direction is provided on the outside of the rotating sleeve 63 to achieve axial limitation. A rotating groove 65 is provided on the inside of the auxiliary ring body 62 to be slidably connected to the rotating bar 64. The rotating sleeve 63 includes a rotating cylinder 66 extending to the outside of the rotating ring 61. The rotating cylinder 66 has a rotating plate 67 opposite the upper end of the rotating ring 61. A corresponding step surface is formed between the rotating cylinder 66 and the rotating plate 67 for mounting the locking mechanism 7. The rotating ring 61 has a plug-in groove 68 symmetrically formed on the outside with respect to its center. The auxiliary ring body 62 has a splicing tooth 69 on the inside that is corresponding to the splicing groove 68. The splicing tooth 69 and the splicing groove 68 realize the clamping connection between the other rotating ring 61 and the auxiliary ring body 62.

[0034] It can be seen that the locking mechanism 7 includes a locking sleeve 71 telescopically connected to the rotating cylinder 66, and anti-slip stripes 72 are distributed on the outer side of the locking sleeve 71. A locking protrusion 73 is arranged at the lower end of the locking sleeve 71. The locking protrusion 73 passes through the rotating piece 67 and is opposite to the upper end of the rotating ring 61. A locking groove 74 for inserting the locking protrusion 73 is opened at the upper end of the rotating ring 61, and an elastic reset member 75 is provided between the locking sleeve 71 and the rotating cylinder 66.

[0035] Obviously, if Figure 7 As shown, when the lower housing 2 is inserted into the human body and connected to the surgical cavity, the internal partition mechanism 8 maintains the cylindrical structure of the lower housing 2. The partition mechanism 8 includes an isolation sleeve 81 connected to the lower end of the lower housing 2. The isolation sleeve 81 and the lower housing 2 are typically made of a transparent material to facilitate observation of the cavity. The isolation sleeve 81 is inserted between the upper housing 1 and the inner side of the lower housing 2. The isolation sleeve 81 is longer than the lower housing 2. The other end of the isolation sleeve 81 is fixed to the upper housing 1 by compression or by an adhesive layer.

[0036] like Figure 5 As shown, an additional protective assembly 9 is installed outside the incision protection sleeve. This assembly is independent of the incision protection sleeve and serves to assist the puncture device in performing the puncture operation. The protective assembly 9 comprises a hard protective cover 91 made of a transparent or translucent material. The protective cover 91 is mounted with a buffer ring 92 through a movable mechanism to directly contact the human body. The buffer ring 92 is covered with a protective layer 93 made of a skin-friendly and flexible material. An adaptive sealing assembly is provided between the buffer ring 92 and the protective cover 91. When the protective cover 91 is fixed to the human body through the movable mechanism and the adaptive sealing assembly, the central opening is used for the insertion of the puncture device.

[0037] from Figure 6 As can be seen, the movable mechanism includes an annular movable groove 94 provided on the inner side of the protective cover 91. A movable ring 95 is provided on the upper end of the buffer ring 92, which is slidably connected to the movable groove 94. The buffer ring 92 can move up and down through the movable ring 95 to fully fit the human body. A movable bar 96 is provided between the upper end of the movable ring 95 and the interior of the movable groove 94, sealing the movable groove 94. When the movable ring 95 moves up and down, the movable bar 96 also moves up and down and maintains the sealed state of the movable groove 94. The adaptive sealing component includes a sealing sleeve 97 provided on the inner side of the protective cover. A sealing gap 98 is left between the sealing sleeve 97 and the protective cover 91. The sealing gap 98 is connected to the movable groove 94 and is filled with colloid. The outlet of the sealing gap 98 is sealed by a sealing membrane 99 made of elastic material. When the protective cover 91 is pressed down, the movable ring 95 in the movable groove 94 and the movable ring 95 are lifted relative to the protective cover 91, thereby squeezing the internal colloid into the sealing gap 98 and causing the sealing membrane 99 to expand and push out until the internal cavity of the protective cover 91 and the surface of the human body form a negative pressure and are adsorbed and fixed.

[0038] To sum up, the principle of this embodiment is that an upper sleeve 1 and a lower sleeve 2 are arranged between the inner sides of the multi-channel sealing cover 11 and the incision protection cover 12 to provide a buffer margin for surgical operations. The upper sleeve 1 and the lower sleeve 2 are connected by an adapter sleeve 3, and the extrusion mechanism 4 between them replaces the conventional threaded connection method. When the upper sleeve 1 and the lower sleeve 2 are plugged and fixed with the adapter sleeve 3, the extrusion mechanism 4 completely blocks the gap between them and locks them, and the outer rubber-coated mechanism 5 realizes circumferential sealing of the adapter sleeve 3 body.
