Abstract
Description
Technical field:
[0001] The invention relates to the technical field of medical devices, in particular to a medical incision self-releasing protection device which can effectively protect clinical surgical incisions and improve the safety and flexibility of surgical operations. Background technology:
[0002] Currently, surgical channel products have been widely used in various surgeries on the market, such as incision protection covers, trocars, single-hole multi-channel sheaths and other products. Among them, incision protection covers are also called incision dilators, which are frequently used in some laparoscopic and surgical operations. Its main function is protection. Specifically, incision protection covers can be used for endoscopic surgery and small incision surgery. During clinical surgery, they can effectively isolate the contact between incision tissue and abdominal viscera, greatly reduce complications at the incision after surgery, and reduce infection at the incision. In addition, they can open the wound to a large extent, make the surgical field of view clearer, and protect the tissue at the incision from damage, which is conducive to shortening the operation time and improving the quality of surgery.
[0003] However, at present, the degree of correlation and coordination between various surgical channel products is low, resulting in certain defects in these products during use. For example, after the puncture or cutting operation, the puncture instrument or scalpel is moved away from the incision, and a hard incision protection cover is inserted through a plate to open the incision and insert the incision protection cover. For incision protection covers made of soft medical materials such as medical silicone, it is easy for the lower part to be unable to unfold smoothly due to squeezing, resulting in unsatisfactory surgical channel establishment; in addition, the incision protection cover still lacks reliable sealing at this stage. The existing technology mostly uses a sealing ring or a sealing cover connected to the upper end of the incision protection cover, which can only provide an operating area on a horizontal plane connected to the upper end of the incision protection cover. For operations that require the insertion of multiple surgical instruments, it is easy to cause interference between instruments. Summary of the invention:
[0004] In view of the shortcomings and deficiencies in the prior art, the present invention proposes a medical incision self-releasing protection device which can effectively protect clinical surgical incisions and improve the safety and flexibility of surgical operations.
[0005] The present invention is achieved by the following measures:
[0006] A medical incision self-release protection device is provided with an airtight component, an incision protection sleeve and an inserter, wherein the incision protection sleeve comprises a sleeve body made of flexible material, an outer clamping ring coaxially arranged with the sleeve body is provided at the upper end of the sleeve body, and a flexible inner clamping ring coaxially arranged with the sleeve body is provided at the lower end of the sleeve body, and a pull-out belt is provided on the inner clamping ring, and the airtight component is installed at the upper end of the incision protection sleeve, characterized in that the inserter is composed of a left inserter shell and a right inserter shell that are buckled together, and after the left inserter shell and the right inserter shell are buckled and connected, a receiving cavity for accommodating the incision protection sleeve is formed, and the lower end of the inserter is in a cone shape that is convenient for penetrating into the incision and pulling away the tissue at the incision, and a limiting plate for limiting the flexible inner clamping ring at the lower end of the sleeve body is provided on the inner wall of the inserter, and after the sleeve body is placed in the receiving cavity, the inner clamping ring is located on the side of the limiting plate close to the lower end of the inserter.
[0007] The limiting plates on the inner wall of the inserter of the present invention are a pair of arc-shaped limiting plates respectively arranged vertically on the inner wall of the left inserter shell and the inner wall of the right inserter shell, the two arc-shaped limiting plates are symmetrically arranged, the arc-shaped limiting plates protrude toward one side of the inserter, and are used to form an arc-shaped inner clamping ring limiting area with an opening downward. Further, in order to improve the limiting effect of the inner clamping ring and ensure that the inner clamping ring is smoothly released and unfolded after the inserter is removed, the height of the arc-shaped limiting plates gradually decreases from the center to both sides to reduce the variable extrusion pressure on the inner clamping ring and avoid its subsequent inability to unfold; a gap of 5-7mm is left between the two arc-shaped limiting plates to facilitate the insertion of the protective cover.
[0008] The upper end of the inserter of the present invention is provided with an annular insertion port connected to the accommodating chamber, the inner diameter of the annular insertion port is adapted to the outer retaining ring of the sleeve body, and the inner diameter of the annular insertion port is larger than the inner diameter of the accommodating chamber, and the annular insertion port is also formed by splicing the left inserter shell and the right inserter shell. Further, the left inserter shell and the right inserter shell are connected through T-shaped interlocking, and the T-shaped interlocking structure includes matching slots and buckles, and the cross-sections of the slots and buckles are T-shaped. The slots and buckles are respectively arranged on the adjacent sides of the left inserter shell and the right inserter shell, specifically, they are arranged on the upper end surfaces of the left inserter shell and the right inserter shell.
[0009] The inserter of the present invention has a conical lower end portion. In order to ensure the reliability of puncture, the conical lower end portion of the inserter is located as a whole at the lower end of the left inserter shell or the right inserter shell, so that the conical lower end portion is an integrated structure. At the same time, a matching step structure is provided at the lower joint of the left inserter shell and the right inserter shell. When viewed from the front of the left inserter shell or the right inserter shell, a V-shaped interlocking structure is presented to ensure that the two can quickly find the correct position in the length direction of the inserter when they are buckled together. In addition, since the left inserter shell and the right inserter shell are located at the accommodating cavity portion away from the conical lower end, that is, Separation can be achieved, so that when the left-side inserter shell is disengaged from the right-side inserter shell (the disengagement operation is to pull it away along the length direction of the inserter), the inner clamping ring can be quickly expanded while the pressure of the detached-side inserter shell disappears, thereby ensuring the insertion stability of the inner clamping ring and the sleeve. In addition, the cone-shaped lower end has an arc-shaped convex part, and further, arc-shaped paddles are symmetrically arranged on both sides of the lower end. The arc-shaped paddles are preferably arranged on the splicing plane of the left-side inserter shell and the right-side inserter shell to form a bidirectional tissue prying part, so that during the puncture and disengagement operation, the tissue at the incision can be pried away, reducing the interference with the insertion of the sleeve.
[0010] The airtight component of the present invention includes a base, which is funnel-shaped. A channel coaxially arranged with the sleeve is provided at the bottom of the base, and a connecting sleeve for connecting to the outer clamping ring of the sleeve is provided outside the channel opening. A cover body is provided at the upper end of the base. The cover body is made of flexible material in an outwardly convex arc shape. At least two insertion channels for inserting surgical instruments are provided on the cover body. The insertion channels are sunken and arranged along the dome section. A channel sealing component is provided at the insertion channel opening. The channel sealing component includes a pressure cover, a protective sheet, a fisheye valve, and an air blocking valve.
[0011] When the present invention is in use, the airtight main body, i.e., the cover body, in the airtight component adopts a "dome-shaped" design, thereby significantly increasing the operating area of the surgical instrument. One to four channels can be set on the "dome", and the distance between the channels is widened to avoid interference between the surgical instruments. At the same time, a double-layer sealing structure is set on the channel: it is composed of a pressure cover, a protective sheet, a fisheye valve, an air-blocking valve, and an outer shell. The fisheye valve and the air-blocking valve form two sealing layers. The fisheye valve sealing layer ensures the airtightness when the instrument enters the channel, and the air-blocking valve ensures the sealing when the instrument does not enter the channel. By adopting a cone-shaped bidirectional tissue opener structure at the front end of the inserter, low-damage puncture of human tissue can be achieved (avoiding damage to human muscle tissue, nerve tissue, etc.), which is beneficial to the recovery of the wound and the occurrence of wound hernia. In addition, a "double-moon arc" baffle structure is adopted inside the inserter, and the inner clamp ring of the protective sleeve is hung in a "C" shape inside the inserter. After the inserter punctures into the human body cavity, the inner clamping ring of the protective sleeve is brought into the human body; the inserter is divided into two parts along the axial direction (inserter left, inserter right), which are inserted together using a "V-shaped interlocking" structure and a "T-shaped interlocking" structure. After the inserter punctures into the human body cavity, the inserter left is first lifted up, and at the same time, the left half of the inner clamping ring of the protective sleeve is automatically unfolded in the human body cavity, and then the inserter right is lifted up again, and at the same time, the right half of the inner clamping ring of the protective sleeve is also automatically unfolded in the human body cavity. At this time, the inner clamping ring of the protective sleeve is completely unfolded in the human body; in the present invention, the protective sleeve is composed of an outer clamping ring, a sleeve body, and an inner clamping ring. The protective sleeve is made of flexible material and can form a flexible channel during surgery for one or more surgical instruments to pass through. The protective sleeve is height-adjustable by turning the outer clamping ring. A pull-out belt is provided on the inner clamping ring of the protective sleeve, so that the protective sleeve can be conveniently pulled out of the wound after the surgery to avoid damaging the wound.
[0012] Compared with the prior art, the present invention has the significant advantages of reasonable structure, simple operation, ability to effectively protect clinical surgical incisions, and ability to improve the safety and flexibility of surgical operations. Description of the drawings:

Specific implementation method:
[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] As attached Figure 1 In view of the shortcomings and deficiencies in the prior art, the present invention proposes a medical incision self-release protection device, which is provided with an airtight component 1, an incision protection sleeve 2 and an inserter 3. The incision protection sleeve 2 includes a sleeve body 8 made of a flexible material, an outer clamping ring 7 coaxially arranged with the sleeve body is provided at the upper end of the sleeve body 8, and a flexible inner clamping ring 9 coaxially arranged with the sleeve body is provided at the lower end of the sleeve body 8. A pull-out belt is provided on the inner clamping ring 9. The airtight component 1 is installed at the upper end of the incision protection sleeve 2. The inserter 3 is composed of a left side and a right side of the sleeve body 8. The inserter 3 is composed of an inserter shell 11 and a right inserter shell 12. After the left inserter shell 11 is buckled and connected with the right inserter shell 12, a receiving cavity for receiving the incision protection sleeve 2 is formed. The lower end of the inserter 3 is in a cone shape that is convenient for penetrating into the incision and pushing aside the tissue at the incision. A limiting plate 19 is provided on the inner wall of the inserter 3 for limiting the flexible inner snap ring 9 at the lower end of the sleeve 8. After the sleeve 8 is placed in the receiving cavity, the inner snap ring 9 is located on the side of the limiting plate 19 close to the lower end of the inserter 3.
[0023] The limiting plate 19 on the inner wall of the inserter 3 of the present invention adopts a pair of arc-shaped limiting plates respectively vertically arranged on the inner wall of the left inserter shell 11 and the inner wall of the right inserter shell 12, and the two arc-shaped limiting plates are symmetrically arranged, and the arc-shaped limiting plates protrude toward the upper end of the inserter 2 to form an arc-shaped inner snap ring limiting area with an opening downward. Further, in order to improve the limiting effect of the inner snap ring 9 and ensure that the inner snap ring 9 is smoothly released and unfolded after the inserter 3 is removed, the height of the arc-shaped limiting plate 19 gradually decreases from the center to both sides to reduce the deformation extrusion pressure on the inner snap ring 9 and avoid its subsequent inability to unfold; a gap of 5-7mm is left between the two arc-shaped limiting plates 19 to facilitate the insertion of the protective cover 8.
[0024] The upper end of the inserter 3 of the present invention is provided with an annular insertion port 20 connected to the accommodating chamber, the inner diameter of the annular insertion port 20 is adapted to the outer retaining ring 7 of the sleeve body 8, and the inner diameter of the annular insertion port 20 is larger than the inner diameter of the accommodating chamber, and the annular insertion port 20 is also formed by splicing the left inserter shell 11 and the right inserter shell 12. Further, the left inserter shell 11 and the right inserter shell 12 are connected via a T-shaped interlocking structure 18 and a V-shaped interlocking structure. The T-shaped interlocking structure 18 or the V-shaped interlocking structure includes a matching slot and a buckle, and the cross-section of the slot and the buckle is T-shaped or V-shaped. The slot and the buckle are respectively arranged on the adjacent sides of the left inserter shell 11 and the right inserter shell 12, specifically, on the upper end surfaces of the left inserter shell 11 and the right inserter shell 12.
[0025] The inserter 3 of the present invention has a conical lower end. In order to ensure the reliability of puncture, the conical lower end of the inserter 3 is located as a whole at the lower end of the left inserter shell 11 or the right inserter shell 12, so that the conical lower end is an integrated structure. At the same time, the lower joint of the left inserter shell 11 and the right inserter shell 12 is provided with a matching step structure. From the front view of the left inserter shell 11 or the right inserter shell 13, a V-shaped interlocking structure is presented to ensure that the two can quickly find the position in the length direction of the inserter 3 when they are buckled together. In addition, since the left inserter shell 11 and the right inserter shell 12 are located at the accommodating cavity part away from the conical lower end, that is, Separation can be achieved, so that when the left-side inserter shell 11 is disengaged from the right-side inserter shell 12 (the disengagement operation is to pull it away along the length direction of the inserter 3), the inner snap ring 9 can be quickly expanded while the pressure of the detached-side inserter shell disappears, thereby ensuring the insertion stability of the inner snap ring 9 and the sleeve 8. In addition, the cone-shaped lower end has an arc-shaped convex part. Further, arc-shaped paddles 23 are symmetrically arranged on both sides of the lower end. The arc-shaped paddles 23 are preferably arranged on the splicing plane of the left-side inserter shell 11 and the right-side inserter shell 12 to form a bidirectional tissue prying component, so that during the puncture and disengagement operations, the tissue at the incision can be pried apart, reducing the interference with the insertion of the sleeve 8.
[0026] The airtight component 1 described in the present invention includes a base 20, which is funnel-shaped. A channel coaxially arranged with the sleeve is provided at the bottom of the base 20, and a connecting sleeve 6 for connecting to the outer clamping ring 7 of the sleeve 8 is provided outside the channel opening. A cover body 21 is provided at the upper end of the base 20. The cover body 21 is made of flexible material and has an outwardly convex arc shape. At least two insertion channels for inserting surgical instruments are provided on the cover body 21. The insertion channels are sunken and arranged along the dome section. A channel sealing component is provided at the insertion channel opening. The channel sealing component includes a pressure cover 13, a protective sheet 14, a fisheye valve 15, and an air blocking valve 16.
[0027] When the present invention is in use, the airtight main body, i.e., the cover body, in the airtight assembly adopts a "dome-shaped" design, which significantly increases the area of the surgical instrument operation area. One to four channels can be set on the dome to increase the distance between the channels and avoid interference between surgical instruments. At the same time, a double-layer sealing structure is set on the channel: it is composed of a pressure cover 13, a protective sheet 14, a fisheye valve 15, an air-blocking valve 16, and a shell 17. The fisheye valve 15 and the air-blocking valve 16 form two sealing layers. The fisheye valve 15 sealing layer ensures the airtightness when the instrument enters the channel, and the air-blocking valve ensures the sealing when the instrument does not enter the channel. By adopting a cone-shaped bidirectional tissue opener structure at the front end of the inserter 3, low-damage puncture of human tissue can be achieved (avoiding damage to human muscle tissue, nerve tissue, etc.), which is beneficial to the recovery of the wound and the occurrence of wound hernia. In addition, a "double-moon arc" baffle (limiting plate 19) structure is adopted inside the inserter 3 to hang the inner clamping ring 9 of the protective sleeve 2 in a "C" shape. Inside the inserter 3, after the inserter 3 punctures into the human body cavity, the inner clamping ring of the protective sleeve 2 is brought into the human body; the inserter 3 is divided into two parts along the axial direction (inserter left, inserter right), which are inserted together using a "V-shaped interlocking" structure and a "T-shaped interlocking" structure. After the inserter 3 punctures into the human body cavity, the left side of the inserter 3 is first lifted upward, and at the same time, the left half of the inner clamping ring 9 of the protective sleeve 2 is automatically unfolded in the human body cavity, and then the right side of the inserter is lifted upward, and at the same time, the right half of the inner clamping ring of the protective sleeve is also automatically unfolded in the human body cavity. At this time, the inner clamping ring of the protective sleeve is fully unfolded in the human body; in the present invention, the protective sleeve is composed of an outer clamping ring, a sleeve body, and an inner clamping ring. The protective sleeve is made of flexible material and can form a flexible channel during surgery for one or more surgical instruments to pass through. The protective sleeve is height-adjustable by turning the outer clamping ring. A pull-out belt is provided on the inner clamping ring of the protective sleeve, so that the protective sleeve can be conveniently pulled out of the wound after the surgery to avoid damaging the wound.
