Description

Technical Field

[0001] This application relates to the field of jaw joint surgery, and in particular to a hand-worn soft tissue separator. Background Technology

[0002] In maxillofacial facelift surgery, soft tissue dissection is a crucial and time-consuming initial step. The thoroughness, precision, and safety of this dissection directly determine the postoperative skin smoothness, firmness, and complication rate, thus profoundly impacting the final aesthetic outcome and patient satisfaction. However, the currently prevalent clinical method of soft tissue dissection—a hybrid approach combining tissue scissors and the surgeon's fingers—has inherent drawbacks such as significant inefficiency and unreliability. These drawbacks are particularly pronounced in certain application scenarios, causing significant negative impacts on patients and the medical system. For example, when performing extensive dissection on large areas of subcutaneous tissue in the maxillofacial region, the blunt dissection of the surgeon's fingers, lacking sharp assistance, results in low efficiency in force transmission and limited coverage, leading to a lengthy and physically demanding process, significantly prolonging surgical time and reducing operating room turnover efficiency. Especially when dealing with dense connective tissue or scar areas, sharp dissection with tissue scissors is necessary. However, during the cutting process with traditional tissue scissors, the delicate balance between the shearing force at the blade and tissue tension is difficult to effectively and in real-time transmit to the surgeon's fingertips via the handle. This state of blind or semi-blind cutting makes it difficult for the surgeon to accurately judge the cutting depth and force, which can easily cause accidental bleeding, such as damage to small blood vessels around the facial nerve branches, damage to important nerves such as facial nerve branches leading to permanent facial paralysis or partial facial muscle dysfunction, and postoperative lymphedema caused by lymphatic vessel damage.

[0003] Furthermore, traditional methods often result in incomplete soft tissue separation or uneven separation planes. Residual adhesions may form depressions or irregular surfaces post-operatively, or hinder the reshaping and even lifting of skin tissue, directly affecting the final aesthetic outcome of the facelift surgery. In summary, the inefficiency, potential tissue damage, and risk of incomplete separation inherent in existing maxillofacial soft tissue submucous separation methods have become bottlenecks restricting the improvement of surgical quality and patient satisfaction. Especially in the context of modern medicine pursuing minimally invasive, precise, and efficient procedures, the need for a new type of surgical instrument that can significantly improve separation efficiency while providing precise tactile feedback to ensure the safety and thoroughness of separation is increasingly urgent. Therefore, the purpose of this invention is to provide a novel maxillofacial soft tissue submucous separation instrument, aiming to overcome the shortcomings of existing technologies such as low efficiency, lack of tactile feedback, and high risk of tissue damage, achieving faster, more precise, and safer soft tissue separation, thereby shortening surgical time, reducing intraoperative bleeding and postoperative complications, and significantly improving the final aesthetic outcome of the surgery.

[0010] Preferably, the wearable structure is located at the end away from the first and second separation portions. The wearable structure includes a recessed portion and a finger adapter. The recessed portion extends recessedly from the outer surfaces of the first and second separation arms, respectively, along the length of the first and second separation arms. The finger adapter is embedded within the recessed portion and is detachably connected to it. The finger adapter is used to fit the user's finger.

[0011] Preferably, the inner wall of the finger adapter is provided with anti-slip patterns to increase the friction between the user's finger and the finger adapter, and the depth of the groove on the first separating arm is different from the depth of the groove on the second separating arm.

When encountering soft tissue that cannot be separated, the first and second cutting edges on the first and second separating arms can be used to cut the soft tissue, ensuring smooth separation. This improves the efficiency of soft tissue separation while ensuring its accuracy. Attached Figure Description

[0027] The present application will now be described in detail with reference to the accompanying drawings.

[0028] The currently prevalent soft tissue dissection method in clinical practice, which combines tissue scissors with the surgeon's fingers, suffers from core defects such as low force transmission efficiency and lack of operational feedback, severely restricting the efficiency and safety of surgery. In the dissection of large areas of subcutaneous tissue in the maxillofacial region, relying solely on blunt dissection with fingers results in a limited range of action, high physical exertion, and slow tissue expansion, leading to a sluggish surgical rhythm and significantly prolonged operation time. While sharp dissection with tissue scissors is necessary when dealing with dense connective tissue or scar areas, traditional tissue scissors lack an effective force feedback mechanism, often leaving the surgeon in a state of "blind cutting" or "semi-blind cutting," making it difficult to precisely control the cutting depth and force. Changes in resistance during cutting cannot be effectively transmitted to the handle, causing a delay in the surgeon's judgment of the tissue break point, greatly increasing the risk of accidental injury. This type of operation is particularly risky in areas where facial nerve branches are distributed, easily causing rupture of small blood vessels leading to bleeding, or directly damaging the nerve causing permanent facial paralysis and partial facial muscle dysfunction, while also increasing the likelihood of lymphatic vessel damage, leading to postoperative lymphedema. The extended operation time not only exacerbates surgeon fatigue but also reduces operating room turnover efficiency and increases the burden on the medical system. Although some active instruments have improved tissue sealing and separation capabilities, their thermal effects spread over a large area, making them unsuitable for delicate manipulation in densely nerve-rich areas. Existing instruments generally exhibit poor adaptability and insufficient control precision when dealing with high-resistance tissues, especially under complex pathological conditions, where the risk of operational failure increases significantly. Overall, current soft tissue separation techniques have shown significant limitations in terms of efficiency, safety, and precision, making it difficult to meet the increasingly demanding requirements of modern surgery for surgical quality and functional preservation.

[0029] In view of this, this application provides a hand-worn soft tissue separator to solve the above problems.

[0030] First Implementation Method

[0031] like Figure 1 The diagram illustrates a hand-worn soft tissue separator, comprising: a first separating arm 1, a second separating arm 2, a first blade 12, and a second blade 22. One end of the first separating arm 1 has a first separating section 11 for performing soft tissue separation. One end of the second separating arm 2 has a second separating section 21 for performing soft tissue separation. The other ends of the first separating arm 1 and the second separating arm 2 are movably connected. The first blade 12 is located at the edge of the first separating arm 1 on the opposite side of the second separating arm 2. The second blade 22 is located at the edge of the second separating arm 2 on the opposite side of the first separating arm 1. The first blade 12 and the second blade 22 are used to move away from or towards each other to cut soft tissue that cannot be separated.

[0032] When soft tissue separation is required, the user can use two fingers to manipulate the first separation arm 1 and the second separation arm 2 respectively, using finger movements to drive the coordinated action of both arms. The first separation arm 1 has a first separation section 11, and the second separation arm 2 has a second separation section 21. During operation, the two separation sections work together to open the target soft tissue, separating it from surrounding muscles or other tissues. During separation, the first separation section 11 and the second separation section 21 will experience resistance from the soft tissue. This resistance is transmitted through the separation sections to the corresponding separation arms and ultimately to the user's fingers, allowing the operator to directly perceive the magnitude and changes in the resistance of the soft tissue. By adjusting the external force applied by the fingers, the user can control the force acting on the first separation arm 1 and the second separation arm 2 in real time, thereby achieving precise force application to the soft tissue and ensuring a timely and effective separation process.

[0033] Furthermore, because the separating mechanism accurately transmits resistance information to the fingers, the operator can perceive the direction of the resistance and adjust the direction and trajectory of the finger's force, flexibly changing the path of soft tissue separation and achieving more precise operational control. In some cases, the connection between soft tissue and adjacent tissues is relatively tight, making it difficult to separate them smoothly with force applied by the fingers alone. Forcibly increasing the force may damage the tissue that needs to be preserved. (Reference) Figure 2 As shown, the first blade 12 and the second blade 22, respectively mounted on the first separating arm 1 and the second separating arm 2, can be used to cut the soft tissue; or, by controlling the first separating arm 1 and the second separating arm 2 to move closer together, the first blade 12 and the second blade 22 can work together to cut from both sides of the soft tissue, thereby completely separating it from the surrounding tissue. This design not only ensures the smooth progress of soft tissue separation but also significantly improves separation efficiency, avoids interruptions due to changing traditional tissue scissors, and saves surgical time. More importantly, since the first separating arm 1 and the second separating arm 2 are precisely positioned to the target area during cutting, the blades can make precise cuts at the predetermined position, effectively reducing positional deviations caused by instrument changes, and further improving the accuracy and safety of soft tissue separation.

[0034] Furthermore, refer to Figure 2 The first cutting edge 12 and the second cutting edge 22 are arranged symmetrically to each other. The first cutting edge 12 extends from the first separating part 11 along the length direction of the first separating arm 1; the second cutting edge 22 extends from the second separating part 21 along the length direction of the second separating arm 2.

[0035] The first blade 12 and the second blade 22 are respectively positioned at the locations of the first separating section 11 and the second separating section 21. This allows the first blade 12 and the second blade 22 to simultaneously reach the target operating position when the first separating section 11 and the second separating section 21 are operated by hand. Therefore, when it is necessary to cut soft tissue using the first blade 12 and the second blade 22, the cutting function can be activated immediately without repositioning, achieving rapid response and precise control. Furthermore, the coordinated operation of the blades and the separating sections not only improves the efficiency of soft tissue separation but also significantly enhances the accuracy and controllability of the separation process.

[0036] In addition, refer to Figure 4 The first blade 12 shown has a first oblique cutting edge at its end, and the second blade 22 has a second oblique cutting edge at its end. The first oblique cutting edge and the second oblique cutting edge can form a cut 4 when the first blade 12 and the second blade 22 are combined.

[0037] During soft tissue separation, in most cases, the first separating arm 1 and the second separating arm 2 need to be brought together and advanced forward. At this time, the merged first separating part 11 and the second separating part 21 together form a conical head. This conical head can smoothly insert into the soft tissue gap and gradually spread it apart, thereby achieving effective separation of the soft tissue from the surrounding original tissue. When encountering a situation where the soft tissue in front is closely connected to adjacent tissue, the first oblique cutting edge of the first blade 12 and the second oblique cutting edge of the second blade 22 can take effect first to cut the soft tissue. The resulting oblique incision 4 can cut in from at least two directions simultaneously, enhancing the cutting effect and ensuring that tightly adhered soft tissue is effectively separated.

[0038] Furthermore, when dealing with smaller, tightly connected areas, the user does not need to open the first separating arm 1 and the second separating arm 2; they only need to keep them closed and apply forward thrust to cut and separate the soft tissue using the blades. This operation method simplifies the control of the arm opening and closing movements, reduces the number of steps, and significantly improves the efficiency and ease of operation of soft tissue separation.

[0039] To ensure that the first and second oblique cutting edges can better cut soft tissue, the included angle of the incision 4 formed by the first and second oblique cutting edges is 45°-60°. This allows for the inclusion of thicker soft tissue while ensuring that the first and second oblique cutting edges can act on the tissue, thereby separating it.

[0040] Furthermore, the cutting angle between the first blade 12 and the second blade 22 is 15°-30°, and the first blade 12 and the second blade 22 intersect each other when the first separating arm 1 and the second separating arm 2 approach each other.

[0041] During soft tissue separation, tissue separation is typically achieved primarily through the spreading action of the first separating part 11 and the second separating part 21. Only when the soft tissue is tightly connected to surrounding tissues and cannot be separated by the separating parts alone, are the first blade 12 and the second blade 22 used for cutting to achieve effective separation by severing the soft tissue. Under normal conditions, the first separating part 11 and the second separating part 21 remain in close contact with each other. Therefore, staggering the first blade 12 and the second blade 22 helps reduce the minimum distance between the two separating parts, thereby improving the accuracy and effectiveness of soft tissue separation in non-cutting mode. When cutting is required, simply opening and closing the first separating arm 1 and the second separating arm 2 briefly drives the first blade 12 and the second blade 22 to perform a shearing action, thus cutting the target tissue.

[0042] Furthermore, designing the cutting angles of the first cutting edge 12 and the second cutting edge 22 to be 15°-30° ensures sufficient sharpness while also balancing strength and durability. This angle range facilitates efficient and rapid cutting of soft tissue, reduces repetitive shearing operations, improves separation efficiency, and lowers the risk of damage to surrounding normal tissue. Further, refer to... Figure 3 The separator also includes two wearable structures 6. The two wearable structures 6 are respectively disposed on the first separating arm 1 and the second separating arm 2. The wearable structures 6 are suitable for wearing on fingers so that the first separating part 11 and the second separating part 21 move away from or closer to each other as the two fingers move.

[0043] To enable more precise control of the first separating arm 1 and the second separating arm 2 by the fingers, the wearable structure 6 needs to be respectively installed on the first separating arm 1 and the second separating arm 2. By wearing the fingers inside the corresponding wearable structure 6, the corresponding separating arm can be precisely controlled.

[0044] Specifically, refer to Figure 3 and Figure 6 The wearable structure 6 shown is located at one end away from the first separating part 11 and the second separating part 21. The wearable structure 6 includes a recessed portion and a finger adapter. The recessed portion extends recessedly from the outer surfaces of the first separating arm 1 and the second separating arm 2, respectively, along the length of the first separating arm 1 and the second separating arm 2. The finger adapter is embedded in the recessed portion and is detachably connected to it. The finger adapter is used to match the user's finger.

[0045] By providing grooves extending along their length on the outer surfaces of the first separating arm 1 and the second separating arm 2, the extension direction of the operator's fingers can be kept highly consistent with the orientation of the first separating arm 1 and the second separating arm 2. This structural design facilitates a high degree of coordination between finger movement and the movement of the separating arms, allowing the operator to precisely control the movement distance of the first separating arm 1 and the second separating arm 2, thereby ensuring movement accuracy and ultimately guaranteeing the accuracy and stability of the soft tissue separation process.

[0046] Furthermore, considering the individual differences in finger size among users, this structure is also equipped with a finger adapter. By providing adapters of various sizes, it can accommodate fingers of different sizes, ensuring that the finger adapter is securely and snugly worn on the operator's fingers. After wearing, the finger adapter is inserted into the groove on the separating arm, allowing direct movement of the fingers to control the first separating arm 1 and the second separating arm 2. This design effectively enhances the linkage and coordination between the fingers and the separating arms, improving the overall accuracy and reliability of the operation.

[0047] Furthermore, the inner wall of the finger adapter is covered with anti-slip patterns to increase the friction between the user's finger and the finger adapter. The depth of the groove on the first separating arm 1 is different from the depth of the groove on the second separating arm 2.

[0048] By incorporating anti-slip patterns on the inner surface of the finger adapter, the friction between the finger and the adapter is effectively increased. During the use of the separator, operation relies on the fingers to move the separator; especially after soft tissue separation, the fingers must apply counter-force to withdraw the first separating arm 1 and the second separating arm 2 from the tissue. Crucially, this instrument is often used in surgical environments where doctors typically wear gloves. The outer surface of the gloves is smoother than bare skin, easily leading to slippage. The anti-slip patterns ensure stable friction between the fingers and the adapter even when wearing gloves, thus guaranteeing a high degree of coordination and reliable operation between the first separating arm 1, the second separating arm 2, and the finger movements.

[0049] Furthermore, due to individual differences in the length of human fingers, the grooves on the first separating arm 1 and the second separating arm 2 are designed with different depths to accommodate the insertion depth of different fingers. This differentiated design ensures that after insertion of fingers of different lengths, the fingertips can all reach the bottom of the corresponding groove, achieving a unified starting point for force transmission, thereby guaranteeing synchronous movement and precise control between the fingers and the separating arms in all operating states.

[0050] Second Implementation Method

[0051] The first embodiment of this application discloses a hand-worn soft tissue separator, in which the first separating arm 1 and the second separating arm 2 are controlled by two fingers respectively, achieving precise control to ensure the separation effect of soft tissue. However, different users have different finger lengths and thicknesses, so the combination of the groove and the finger adapter cannot meet the needs of all users' hand shapes.

[0052] In view of this, the improvement of the second embodiment of this application compared with the first embodiment is that the wearable structure 6 includes: a base and a ring. The base is respectively disposed on the outer surface of the first separating arm 1 and the second separating arm 2. The ring is connected to the base, and the user's finger passes through the ring to control the movement of the first separating arm 1 and the second separating arm 2.

[0053] By incorporating a finger ring and base, users can thread their fingers through the ring when using the separator, ensuring a stable fit. The finger ring design accommodates various hand shapes, freeing wearers from the constraints of the groove size and improving operational comfort and usability. The finger ring and base feature a detachable connection, allowing users to replace the ring with different sizes to suit various finger shapes. This design significantly expands the separator's applicability to a wider range of users and enhances its versatility and ergonomics.

[0054] Furthermore, the base is equipped with a turntable, the turntable has a connecting part, and the connecting part has a buckle that matches the ring for securing the ring.

Furthermore, the finger ring and base feature a detachable connection, allowing users to replace the ring with different sizes to suit various finger shapes. This design significantly expands the separator's applicability to a wider range of users and enhances its versatility and ergonomics.

[0056] Third Implementation Method

[0057] The first and second embodiments of this application disclose a hand-worn soft tissue separator, which separates soft tissue by controlling the first separating arm 1 and the second separating arm 2 with two fingers. The separation of soft tissue mainly relies on the combined state of the first separating arm 1 and the second separating arm 2, with the first separating part 11 and the second separating part 21 extending into the subcutaneous tissue to peel it off. However, when encountering tightly packed soft tissue that is difficult to separate, shearing is required. When the first separating arm 1 and the second separating arm 2 move closer or further apart under the skin, the line of sight is obstructed, which may affect the cutting accuracy of the first blade 12 and the second blade 22.

[0058] In view of this, refer to Figure 3 , Figure 6 The improvement of the third embodiment of this application compared with the first and second embodiments is that the ends of the first separating arm 1 and the second separating arm 2 that are away from the first separating part 11 and the second separating part 21 are hinged by a hinge 5.

[0059] The first separating arm 1 and the second separating arm 2 are hinged together by hinge 5, allowing them to open and close relative to each other under finger-driven operation, thus simulating the cutting action of tissue scissors. Since the first separating arm 1 and the second separating arm 2 are fixedly connected by hinge 5, their relative movement trajectory is effectively limited, ensuring that the first cutting edge 12 and the second cutting edge 22 move along a predetermined path under the drive of their respective separating arms, meeting the precision requirements of cutting operations during surgery. The design of hinge 5 also allows for precise control of the separation distance between the first separating arm 1 and the second separating arm 2 during the opening process, enabling adjustment according to the thickness of different soft tissues and cutting needs, adapting to diverse clinical application scenarios.

[0060] Furthermore, the first separation portion 11 and the second separation portion 21 are arranged opposite to each other, and the first separation portion 11 and the second separation portion 21 are provided with a blunt edge on the side opposite to each other. The edge is arc-shaped along its length direction and the blunt edge has a predetermined radius of curvature.

[0061] During soft tissue separation, the first separating part 11 and the second separating part 21 are mainly inserted into the subcutaneous tissue, and tissue separation is achieved through a spreading action. The blunted edges on the first separating part 11 and the second separating part 21 effectively prevent accidental cutting or damage to the surrounding subcutaneous tissue during insertion and movement of the separator. The arc-shaped blunted edges allow for a smooth transition during the advance or opening / closing movement of the separator, preventing rigid collisions with the tissue, reducing tissue traction and localized stress concentration, thereby improving operational safety and tissue protection.

[0062] Fourth Implementation Method

[0063] In the process of using a tissue separator, there are scenarios where it is necessary to cut soft tissue using the first blade 12 and the second blade 22 to deal with situations where some tissues are too dense. However, after the first blade 12 and the second blade 22 cut the soft tissue, the cut tissue remains between the first separating arm 1 and the second separating arm 2, thus affecting the subsequent separation process.

[0064] In view of this, the improvement of the fourth embodiment of this application compared with the third embodiment is that, referring to Figure 4 , Figure 5 , Figure 6 The separator also includes two guides 3, which are respectively disposed on the opposite side of the first separating arm 1 and the second separating arm 2. The guides 3 are respectively connected to the first blade 12 and the second blade 22, and are opposite to the end of the first separating arm 11 and the second separating arm 21, so as to guide the cut soft tissue to the outside.

[0065] Guide sections 3 are provided at the ends of the first blade 12 and the second blade 22. After soft tissue shearing, tissue fragments remaining between the first blade 12 and the second blade 22 are smoothly pushed to the guide section 3 as the separator is pushed forward by the fingers. As the separator continues to move forward, the soft tissue accumulated on the guide section 3 gradually accumulates and is eventually discharged from the end of the first separating arm 1 and the second separating arm 2 away from the separating section. This effectively prevents the sheared tissue from accumulating between the two arms, ensuring smooth instrument movement and a clear surgical field.

[0066] Finally, it should be noted that those skilled in the art will understand that many technical details have been presented in the embodiments of this application to facilitate a better understanding of the present application. However, even without these technical details and various changes and modifications based on the above embodiments, the technical solutions claimed in the claims of this application can be substantially achieved. Therefore, in practical applications, various changes can be made to the above embodiments in form and detail without departing from the spirit and scope of this application.
