Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a minimally invasive orthopedic surgical tool. Background Art

[0002] With the deepening of sports medicine research and the increasing application of arthroscopic technology, more and more joint diseases can be diagnosed or treated through minimally invasive surgical methods, such as rotator cuff injury, shoulder labrum injury, SLAP injury, patellar retinaculum injury, meniscus injury, etc.

[0003] The core operation of arthroscopic diagnosis of the above diseases is to determine the location, range, depth and nature of the lesion through exploration with a probe hook; specifically in the field of shoulder arthroscopy, it is manifested in determining the type and degree of rotator cuff or labrum injury, the type and distribution of articular cartilage degeneration, and the location and degree of tendon dislocation through exploration with a probe hook.

[0004] The core of arthroscopic surgical treatment is to remove the diseased tissue or use wire anchors or compression screws made of various materials to reconstruct the attachment points of tendons or ligaments on the bone; specifically in the field of shoulder arthroscopy, it is reflected in the use of inner-row wire anchors alone or in combination with outer-row compression screws to reconstruct the attachment points of the rotator cuff tendons (usually the supraspinatus) on the humeral head, and the use of wire anchors to suture damaged labral cartilage or suspend and fix the dislocated long head of the biceps tendon; ultimately, the essence and key link of arthroscopic surgery to reconstruct the soft tissue-bone connection is to use the sutures of the wire anchors to weave or suture soft tissues such as tendons or ligaments, and the thread grabber needs to be used repeatedly during the suturing process.

[0005] It can be seen that the diagnosis and treatment of joint diseases require repeated use of probes and thread graspers.

[0006] In order to reconstruct the soft tissue-bone connection in the narrow shoulder joint cavity with wire anchors under the field of view of shoulder arthroscopy, it is very important to properly manage the anchor lines during the operation.

[0007] The traditional surgical method uses a hard probe to detect the lesion or injury, separate and straighten the anchor wire. The anchor wire is grasped by a single-direction wire grasping forceps. The traditional surgical method has the following disadvantages: there are many types of traditional surgical tools, and the function of a single surgical tool is single. However, the joint cavity space is small and cannot accommodate more surgical tools. Therefore, the surgical tools need to be replaced frequently during the operation, which will increase the soft tissue damage around the surgical incision, prolong the operation time and increase the risk of infection.

DETAILED DESCRIPTION

[0040] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0041] In the present disclosure, unless otherwise stated, directional words such as "upper" and "lower" generally refer to the relative "upper" and "lower" of the corresponding parts in the use state in the direction of gravity, and "inside" and "outside" refer to the "inside" and "outside" relative to the corresponding parts' own contours. In addition, the terms "first" and "second" used in the present disclosure are to distinguish one element from another and do not have order and importance. In the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements.

[0042] With the deepening of sports medicine research and the increasing application of arthroscopic technology, more and more joint diseases can be diagnosed or treated through minimally invasive surgical methods, such as rotator cuff injury, shoulder labrum injury, SLAP injury, patellar retinaculum injury, meniscus injury, etc.

[0043] The core operation of arthroscopic diagnosis of the above diseases is to determine the location, range, depth and nature of the lesion through exploration with a probe hook; specifically in the field of shoulder arthroscopy, it is manifested in determining the type and degree of rotator cuff or labrum injury, the type and distribution of articular cartilage degeneration, and the location and degree of tendon dislocation through exploration with a probe hook.

[0044] The core of arthroscopic surgical treatment is to remove the diseased tissue or use wire anchors or compression screws made of various materials to reconstruct the attachment points of tendons or ligaments on the bone; specifically in the field of shoulder arthroscopy, it is reflected in the use of inner-row wire anchors alone or in combination with outer-row compression screws to reconstruct the attachment points of the rotator cuff tendons (usually the supraspinatus) on the humeral head, and the use of wire anchors to suture damaged labral cartilage or suspend and fix the dislocated long head of the biceps tendon; ultimately, the essence and key link of arthroscopic surgery to reconstruct the soft tissue-bone connection is to use the sutures of the wire anchors to weave or suture soft tissues such as tendons or ligaments, and the thread grabber needs to be used repeatedly during the suturing process.

[0045] It can be seen that the diagnosis and treatment of joint diseases require repeated use of probes and thread graspers.

[0046] In order to reconstruct the soft tissue-bone connection in the narrow shoulder joint cavity with wire anchors under the field of view of shoulder arthroscopy, it is very important to properly manage the anchor lines during the operation.

[0047] The traditional surgical method uses a hard probe to detect the lesion or injury, separate and straighten the anchor wire; and grab the anchor wire with a single-direction opening and closing wire grasper. The traditional surgical method has the following disadvantages: There are many types of traditional orthopedic minimally invasive surgical tools, and the function of a single orthopedic minimally invasive surgical tool is single. However, the joint cavity space is small and cannot accommodate more orthopedic minimally invasive surgical tools. Therefore, orthopedic minimally invasive surgical tools need to be frequently replaced during surgery, which will increase soft tissue damage around the surgical incision, prolong the operation time and increase the risk of infection.

[0048] Please refer to Figures 1 to 3 An embodiment of the present application provides an orthopedic minimally invasive surgical tool, comprising: a fixed forceps handle 1, a movable forceps handle 2, a sleeve 3, a probe hook 4 and a wire grasping assembly 5.

[0049] Among them, the fixed clamp handle 1 is provided with a parallel first through hole 101 and a second through hole 102 in sequence from bottom to top; the movable clamp handle 2 includes a driving rod 201 and a guide rod 202 vertically connected to the driving rod 201; the guide rod 202 passes through the first through hole 101 of the fixed clamp handle 1, and the driving rod 201 is provided with a third through hole 203 which is colinear with the second through hole 102 of the fixed clamp handle 1.

[0050] The first end of the sleeve 3 is rotatably connected to the second through hole 102 of the fixed clamp handle 1. The probe hook 4 includes a rod portion 401, the first end of the rod portion 401 passes through the sleeve 3 and is rotatably connected to the third through hole 203 of the driving rod 201, and the second end of the rod portion 401 has a first hook portion 402. The wire grabbing assembly 5 includes a wire grabber and a control unit, the wire grabber is located at the second end of the sleeve 3, and the control unit is located at the first end of the sleeve 3, and the control unit is used to control the opening and closing of the wire grabber.

[0051] In the embodiments of the present application, on the one hand, reference is made to Figures 4 to 14 , since the sleeve 3 is rotatably connected to the fixed clamp handle 1, and the second end of the sleeve 3 is provided with a wire grabber of the wire grabbing assembly 5, and the first end of the sleeve 3 is provided with a control unit of the wire grabbing assembly 5. The surgeon holds the fixed clamp handle 1 and the movable clamp handle 2, and can control the opening and closing of the wire grabber by operating the control unit. By rotating the sleeve 3, the wire grabber can be rotated around the central axis of the sleeve 3, which is convenient for the surgeon to operate the wire grabber. On the other hand, the probe hook 4 passes through the sleeve 3 and is rotatably connected to the driving rod 201 of the movable clamp handle 2. The surgeon can control the length of the probe hook 4 extending out of the sleeve 3 by controlling the distance between the movable clamp handle 2 and the fixed clamp handle 1, and the hook portion of the probe hook 4 can be rotated around the central axis of the probe hook 4 by rotating the rod portion 401 of the probe hook 4.

[0052] Therefore, the orthopedic minimally invasive surgical tool provided in the embodiment of the present application can allow the surgeon to operate with one hand in a narrow joint cavity. The probe hook 4 can be extended and retracted relative to the sleeve 3, and can also rotate around the central axis of the sleeve 3, so as to facilitate the surgeon to explore lesions and injuries in all directions; the wire grasping assembly 5 can rotate around the central axis of the sleeve 3 to grasp the anchor wire in all directions. The orthopedic minimally invasive surgical tool provided in the present application has various functions, which avoids the damage to the soft tissue around the surgical incision caused by frequent replacement of surgical instruments, and helps to simplify the operation, shorten the operation time, and reduce the risk of perioperative complications.

[0053] In one embodiment of the present application, the thread catcher may include: a first hinge hole 303 and an opening and closing rod 501. The first hinge hole 303 is arranged on the sleeve 3 at a position close to the second end of the sleeve 3; the first end of the opening and closing rod 501 has a second hinge hole 5011 and a third hinge hole 5012, wherein the second hinge hole 5011 is located on a side of the opening and closing rod 501 close to the sleeve 3, and the third hinge hole 5012 is located on a side of the opening and closing rod 501 away from the sleeve 3, and the second end of the opening and closing rod 501 has a second hook 5013 extending toward the sleeve 3, and the second hinge hole 5011 is connected to the first hinge hole 303 through a hinge shaft. The control part may include a control disk 502, a control rod 503, and a first elastic member 504; the control disk 502 has a fourth through hole, the control disk 502 can be movably mounted on the sleeve 3, the first end of the control rod 503 is hinged to the control disk 502, and the second end is hinged to the third hinge hole 5012; the first elastic member 504 is located between the control disk 502 and the fixed clamp handle 1.

[0054] In this case, the surgeon holds the orthopedic minimally invasive surgical tool and pushes and pulls the control plate 502 along the sleeve 3 with his fingers to open or close the opening and closing rod 501. Figures 1 to 3Specifically, the control disk 502 is pulled back along the sleeve 3, and the control rod 503 can control the opening and closing rod 501 to rotate counterclockwise to open. At this time, the wire grabber can be used to grab the anchor line. The control disk 502 is moved forward along the sleeve 3, and the control rod 503 can control the opening and closing rod 501 to close clockwise. At this time, the anchor line can be moved. When the anchor line moves to the target position and needs to be released, the control disk 502 is pulled back along the sleeve 3, and the control rod 503 can control the opening and closing rod 501 to rotate counterclockwise to open and release the anchor line. In order to make the wire grabber grab the anchor line more reliably and prevent the anchor line from falling out during the pulling process, the second end of the sleeve 3 has a third hook portion 301 extending toward the second hook portion 5013. The first elastic member 504 can be a coil spring, which is sleeved on the sleeve 3 between the control disk 502 and the fixed clamp handle 1.

[0055] In order to prevent the control disk 502 from rotating during the movement along the sleeve 3, the control disk 502 has a fourth through hole, and a rotation-stopping structure is provided between the control disk 502 and the sleeve 3, wherein the rotation-stopping structure is a protrusion provided on the sleeve 3, and a groove provided in the fourth through hole corresponding to the protrusion. In another embodiment, the positions of the protrusion and the groove can be interchanged, that is, the groove is provided on the sleeve 3, and the protrusion is provided in the fourth through hole.

[0056] In the examples of this application, reference is made to Figures 1 to 3 The orthopedic minimally invasive surgical tool may further include a first limiting plate 6, the first limiting plate 6 having a first screw hole, the first end of the sleeve 3 having a first connecting thread matching the first screw hole; the sleeve 3 having a first dial wheel 302 fixedly connected to the sleeve 3; wherein the first dial wheel 302 and the first limiting plate 6 are respectively located on both sides of the fixed clamp handle 1. In this way, after the first end of the sleeve 3 passes through the second through hole 102 of the fixed clamp handle 1, one side of the fixed clamp handle 1 is the first dial wheel 302, and the other side is threadedly connected to the sleeve 3 through the first limiting plate 6, so that the sleeve 3 and the fixed clamp handle 1 are rotatably connected. The sleeve 3 can be rotated by turning the first dial wheel 302 with a finger, thereby driving the thread grabber connected to the second end of the sleeve 3 to rotate.

[0057] It should be noted that in the embodiment of the present application, the thread length of the first end of the sleeve 3 needs to satisfy that when the first limit plate 6 is threadedly connected to the sleeve 3, the distance between the first pulley 302 and the first limit plate 6 is greater than the thickness of the fixed clamp handle 1, so that the sleeve 3 can rotate freely in the second through hole 102 of the fixed clamp handle 1.

[0058] In the examples of this application, reference is made to Figures 1 to 3, the rod 401 of the movable clamp handle 2 has a second limiting plate 4011 fixedly connected to the rod 401, the first end of the rod 401 of the probe hook 4 has a second connecting thread, and the orthopedic minimally invasive surgery tool also includes a second dial wheel 7 matched with the second connecting thread; wherein the second limiting plate 4011 and the second dial wheel 7 are respectively located on both sides of the driving rod 201. In this way, after the rod 401 of the probe hook 4 passes through the third through hole 203 of the driving rod 201 of the movable clamp handle 2, one side of the driving rod 201 is the second limiting plate 4011, and the other side is threadedly connected to the rod 401 through the second dial wheel 7, thereby realizing the rotatable connection between the probe hook 4 and the sleeve 3. The rotation of the probe hook 4 can be realized by turning the second dial wheel 7 with a finger, thereby driving the first hook 402 to rotate.

[0059] It should be noted that in the embodiment of the present application, the thread length of the first end of the rod portion 401 of the probe hook 4 needs to satisfy the requirement that when the second dial wheel 7 is threadedly connected to the rod portion 401, the distance between the second dial wheel 7 and the second limit plate 4011 is greater than the thickness of the driving rod 201 of the movable clamp handle 2, so that the probe hook 4 can rotate freely in the third through hole 203 of the driving rod 201.

[0060] In the examples of this application, reference is made to Figures 1 to 3 The orthopedic minimally invasive surgical tool may further include a second elastic member 810, and the second elastic member 8 is located between the fixed clamp handle 1 and the driving rod 201. In this case, when the surgeon only needs to use the wire grasping assembly 5, the probe hook 4 can be reliably in the sleeve 3. When the surgeon needs to use the probe hook 4, he only needs to drive the movable clamp handle 2 closer to the fixed clamp handle 1 to extend the probe hook 4 from the sleeve 3, so that the orthopedic minimally invasive surgical tool can be quickly converted from the wire grasper to the probe hook 4, saving surgical time and eliminating the trouble of replacing the orthopedic minimally invasive surgical tool.

[0061] In the examples of this application, reference is made to Figures 1 to 3 The movable pliers handle 2 is T-shaped, and the guide rod 202 is vertically connected to the middle of the driving rod 201; the third through hole 203 is located at the end of the driving rod 201 on the upper side of the guide rod 202;

[0062] In one embodiment, the second elastic member 8 may be a U-shaped spring, one end of which is connected to the fixed clamp handle 1, and the other end of which is connected to the end of the driving rod 201 located at the lower side of the guide rod 202. In other embodiments, the second elastic member 8 may also be a coil spring, which may be sleeved on the guide rod 202, and the present application does not limit this.

[0063] In the examples of this application, reference is made to Figures 1 to 3, the first through hole 101 is a non-circular hole, and the cross section of the guide rod 202 matches the shape of the first through hole 101. The cross section of the guide rod 202 can be a triangle, a quadrilateral, a pentagon, etc., and correspondingly, the first through hole 101 can be a triangular hole, a quadrilateral hole, or a pentagonal hole. Setting the first through hole 101 as a non-circular hole and the cross section of the guide rod 202 as a non-circular hole can prevent the guide rod 202 from rotating in the fixed clamp handle 1, thereby better limiting the rotation of the movable clamp handle 2 and improving the operating accuracy of the orthopedic minimally invasive surgical tool.

[0064] In the examples of this application, reference is made to Figures 1 to 3 The outer circumferences of the first dial wheel 302 and the second dial wheel 7 are both provided with wheel patterns. In this way, the friction between the first dial wheel 302, the second dial wheel 7 and the finger can be increased, so as to facilitate better dialing of the first dial wheel 302, the second dial wheel 7.

[0065] The working principle of the embodiment of the present application is explained below by taking the use of orthopedic minimally invasive surgical tools in joint surgery as an example.

In the fourth third state, the first hook portion 402 of the orthopedic minimally invasive surgical tool is downward and extends out of the sleeve 3, the wire grabber is located below the sleeve 3 and the opening is in a closed state. When the movable clamp handle 2 compresses the U-shaped spring under the guidance of the guide rod 202 and approaches the fixed clamp handle 1, the probe hook 4 connected to the movable clamp handle 2 extends out of the front end of the sleeve 3 by a corresponding length. In actual surgical operations, if it is necessary to explore lesions, injuries, or to separate and straighten cables, the surgeon can use the middle, ring, and little fingers and thumb to exert force relative to each other to make the held fixed clamp handle 1 and movable clamp handle 2 approach each other to extend the probe hook 4.
