Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of fascia release instruments, and particularly relates to an instrument for fascia release through rotation and traction, and specifically relates to a release instrument combining rotation and traction. BACKGROUND

[0002] At present, for the problem of nerve compression caused by tight fascia of the elbow, wrist, ankle and the like in clinical practice, a larger surgical incision is usually made to find the compression position, and then a cutting instrument is used to cut part of the fascia for release. This method causes great trauma and also causes great damage to the fascia.

[0003] Although the needle knife treatment opens a small incision at the wrist, such as the prior art CN202421257249.6 fascia release instrument, although it solves the problem of a large surgical incision, the entire operation still needs to send the cutting blade into the operation site to cut part of the fascia for release, which still causes great damage to the fascia. However, for some low compression, the cutting method will cause great damage.

[0004] Therefore, in view of the above technical problems, a release instrument combining rotation and traction is provided. SUMMARY

[0005] For the release method of low compression, a straight release needle is also used, which is inserted into the release position to repeatedly enter and exit in a channel through repeated pulling to achieve small-range release by extruding the surrounding tissue. However, this release method has poor effect, and therefore a technical solution is needed to effectively release through repeated pulling after entering through a small incision.

[0006] The application sets the releasing part with multiple bending structures at the front end of the releasing needle, connects the pulling part, and further sets the operation handle connected with the pulling part; in use, first, a surgical incision is constructed, then the releasing part is sent to the position to be released, so that the pulling part has a distance of at least 4-5 cm to enter the subcutaneous position inside the surgical incision; then the operation handle is rotated, the rotation of the operation handle drives the rotation of the bending structure of the releasing part, the rotation of the bending structure winds part of the fascia outside the bending structure, so that the treatment of the fascia in a larger range is realized, finally, the fascia wound outside the bending structure is pulled outwards in a rapid outward pulling manner, so as to pull the fascia around the wound fascia, the releasing range is large, when the withdrawal distance is to a certain distance, the winding force is less than the fascia resetting force, the fascia is released from the bending structure and returns to the original position; the withdrawal movement distance is not greater than the distance of the pulling part, so as to ensure that the bending structure will not be pulled out of the surgical incision in a single outward pulling, this way can avoid the influence of the irregular bending of the bending structure on the wound position, and ensure that the whole releasing process is carried out in the subcutaneous tissue inside the surgical incision.

[0007] The specific technical scheme is as follows: a releasing instrument combined with rotating winding and pulling actions, comprising:

[0008] The releasing part comprises bending structures facing opposite directions, each direction comprises at least two bending structures, one bending structure comprises two intersecting sections and a bend formed by the intersecting sections;

[0009] The pulling part is a straight rod connected with the releasing part, the length of the straight rod is greater than or equal to 3 cm, which is used for ensuring sufficient movement distance when the pulling part is withdrawn, and ensuring that the releasing part is maintained inside the surgical incision during operation;

[0010] The operation handle is connected with the pulling part, which is used for rotating and pulling operations outside the body to complete the rotating winding releasing and withdrawal pulling releasing actions of the releasing part, and finally ensure the releasing operation on the human body releasing area.

[0011] Further, the distances from the vertices of the multiple bending structures facing the same direction to the longitudinal axis of the pulling part are different, through this setting, an inclined bending structure which is not symmetrical to the longitudinal axis of the pulling part can be constructed.

[0012] Further, the same bending structure is the same bending structure, and the two intersecting segments constituting the bending structure are a first segment and a second segment, the first segment and the second segment are different in length, and the angle bisector of the bending structure is perpendicular to the axis of the pulling part; through such a setting, an effective bending structure deviating from the axis of the pulling part can be constructed, so that each bending is different in distance from the longitudinal axis of the pulling part; in addition, the same setting of each bending structure can ensure that each bending structure gives the same winding force to the loosening part during rotation operation, avoiding the difference in loosening effect caused by different bending forces on different parts, which ultimately affects the overall loosening effect.

[0013] Further, the two adjacent bending structures with different orientations are constructed into an S-bending structure, each loosening part contains at least two S-bending structures, the longitudinal distance between the two bending vertices of each S-bending structure is in the range of 3-8mm, and the transverse distance of each S-bending is in the range of 6-10mm. Such a setting can ensure the winding strength, and will not form a large incision during entry and exit.

[0014] Further, the number of S-bending structures and the interval of S-bending structures are set according to the size of the longitudinal distance of the loosening area. Specifically, the increase of the longitudinal distance of the loosening part is realized by increasing the interval distance of the two adjacent S-bending structures, so as to improve the overall longitudinal loosening range, while for the loosening area with short longitudinal distance, the continuous S-bending structure mode can be set to improve the operation flexibility and reduce the interference to the surrounding tissue.

[0015] For example: for the loosening area with low fascia tightness, the rotation winding needs small force, two S-bending structures are set, and the distance between the two S-bending structures is greater than 1cm; such structure uses only the S-bending structures at both ends to realize the winding loosening of all fascia in the longitudinal direction of the loosening area corresponding to the two S-bending structures, and then realizes the loosening in the two directions by pulling back and withdrawing.

[0016] For the case that needs large range loosening in both transverse and longitudinal directions, such as the area of the posterior occipital part and the skin surface with scar, small range loosening cannot achieve effective loosening stimulation, three S-bending structures with interval of 4-6mm are set, and each two S-bending structures are connected by a connecting short rod parallel to the longitudinal axis of the pulling part; the length of the pulling part is 10cm; the specific size can be controlled in the range of 8-12cm. Through the setting mode of three S-bending structures with interval, the three S-bending structures can form strong winding force when transversely loosening, so as to make the fascia better wound in the loosening part, and the transverse loosening effect is better. In addition, because the interval distance of the S-bending structures is set to 5-8mm, the longitudinal loosening range can also be expanded.

[0017] Alternatively, for the loosening of the sacroiliac joint area, two continuous S-bending structures are set without an interval.

[0018] Furthermore, the operating handle includes a grip, a connecting part, and a blocking part.

[0019] The grip portion is arranged in a direction parallel to the longitudinal axis of the pull-out portion.

[0020] The connecting part has one end connected to the pull-out part and the other end connected to the first end of the grip part; the connecting part is used to achieve a distance greater than 15mm between the longitudinal axis of the grip part and the pull-out part.

[0021] The blocking part, connected to the second end of the grip, is used to prevent the fingers holding the grip from leaving the grip during a rapid pull-back operation, thus preventing the rapid pull-back action from being completed.

[0022] The operating handle is formed in one piece and is made of the same material, but the operating handle and the pull-out part are made of different materials. Specifically, the pull-out part and the release part are made of materials with higher density and toughness, while the operating handle is made of lightweight material. The operating handle is a plate structure with a thickness of 4mm or more. This design can take into account the strength of the front material without adding too much weight.

[0023] Furthermore, the connecting part includes an arc-shaped structure with an arc angle of 90 degrees and a radius of not less than 2 cm.

[0024] Furthermore, the blocking part extends symmetrically from the second end of the gripping part, the distance from the end of the protruding part to the gripping part is less than or equal to 8mm, the blocking part has curvature, and in cross-sectional view, the outer surface of the blocking part is an arc-shaped surface; and the distance between the blocking part and the gripping part in the vertical direction is less than or equal to 30mm.

[0025] Furthermore, the plane of symmetry of the operating handle is perpendicular to the plane containing the bent structure.

[0026] Furthermore, the rear end of the pull-out section is connected to a combined section that is larger than the pull-out section at one end. The combined section has an annular groove for assembly, and the groove contains a rod. Inclined assembly holes are provided on both sides of the section, and the combined rod is inserted into the annular groove through the assembly hole. The width of the annular groove is smaller than the diameter of the combined rod. By hammering the combined rod into the annular groove and making it in close contact with the rod inside the groove, the rod inside the groove can be slightly deformed when hammered in. This inclined design can prevent the pull-out rod from rotating after assembly. Because the size of the annular groove is small, it can prevent the pull-out section from moving horizontally, ensuring the stability of the pull-out section and the operating handle after assembly, and ensuring that there will be no loosening or falling off during rotation and pulling.

[0027] Technical effect

[0028] By designing and coordinating the loosening section, the pulling section, and the operating handle, it is possible to ensure loosening in both directions—wrap and pull—at the location to be loosened, thus meeting the loosening requirements. Of course, to avoid the impact of the bending structure on the surgical incision location, the withdrawal distance is controlled to be no greater than the distance of the pulling section, so as to ensure that the bending structure will not come out of the surgical incision during a single outward pull. The setting of the pulling section, which is no less than 3cm, can greatly avoid the irregular bending of the bending structure from stimulating the wound location and affecting the incision location, while ensuring that the entire loosening process is carried out subcutaneously within the surgical incision.

[0029] By setting different distances from the apex of the bends of multiple bends facing the same direction to the longitudinal axis of the pull section, a larger entanglement radius can be formed under the premise of a smaller release section. This avoids excessive damage to the tissues along the way when the instrument enters and exits, while ensuring a larger entanglement radius and maximizing the release range of the area to be released.

[0030] The use of multiple S-bends ensures balanced force application during the rotational winding operation, thus guaranteeing structural stability.

[0031] Different S-bend structures and intervals are set for different loosening positions to ensure sufficient gripping force for rotation and winding, so that the tissue rotates to the loosening part, and the intervals are set to increase the loosening in the longitudinal range.

[0032] The design of the connecting part of the operating handle allows for a certain distance between the pull-out part and the grip part, forming a force-saving structure that effectively ensures the application of force during rotation and winding. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0052] refer to Figures 1-6 A release device combining rotational winding and pulling actions, comprising:

[0053] The loosening section 1 includes bending structures facing opposite directions, with each direction including at least two bending structures. Each bending structure includes two intersecting segments and a bend formed by the intersecting segments; that is, the bending structures bend in two directions, which are opposite to each other.

[0054] The pull-out section 2 is a straight rod connected to the release section 1. The length of the straight rod is greater than or equal to 3cm. It is used to ensure that there is sufficient movement distance when pulling back, and to ensure that the release section 1 is kept inside the surgical incision during the operation.

[0055] The operating handle 3 is connected to the pull-out part 2 and is used to perform rotation and pull-out operations outside the body to complete the rotation, winding, and loosening actions of the loosening part 1 and the retraction and pull-out loosening actions, ultimately ensuring the loosening operation of the area of ​​the human body that needs to be loosened.

[0056] Specifically, fascia includes deep fascia and superficial fascia. Deep fascia refers to the fascia above and below muscles, as well as the periosteum, while superficial fascia refers to the fascia in the fat layer between the skin and muscles. This instrument is mainly applied to the superficial fascia, but it can also be applied to the muscle layer. One purpose of release is to resolve adhesions in the tissues. Secondly, it artificially creates a localized trauma that the body can tolerate within the fascial layer. This localized trauma activates the body's overall repair mechanisms, allowing for the simultaneous repair of the local area and the activation of cell proliferation in other tissues throughout the body. This puts the entire body in a state of activated repair, including the immune and nervous systems. During this repair process, various systems release cytokines, which are regulated by the brain, keeping the brain in an excited state and cooperating in the overall repair process. For example, releasing and stimulating the posterior thoracic spine can effectively stimulate the meridians, achieving the goal of treating lung diseases. Similarly, releasing and stimulating the anterior side can achieve the same therapeutic effect as the posterior side.

[0057] By setting and coordinating the loosening part 1, the pulling part 2, and the operating handle, it is possible to ensure that the entanglement and traction of the position to be loosened can be achieved in both directions, so that the loosening range meets the requirements. Of course, in order to avoid the influence of the bending structure on the surgical incision position, the withdrawal movement distance is controlled to be no greater than the distance of the pulling part 2, so as to ensure that the bending structure will not come out of the surgical incision when pulled outward once. The setting of the pulling part 2, which is no less than 3cm, can greatly avoid the irregular bending of the bending structure from stimulating the wound position and affecting the incision position, and ensure that the entire loosening process is carried out subcutaneously within the surgical incision.

[0058] refer to Figure 2 and Figure 4The distances from the apex of the bends of multiple bends facing the same direction to the longitudinal axis of the pull-out section 2 are different. If there are more than three bends facing the same direction, the distances from the apex of the bends to the longitudinal axis of the pull-out section 2 increase or decrease sequentially. Specifically, the bend closest to the pull-out section 2 is defined as the first bend 111, followed by the second bend, the third bend 113, the fourth bend, and so on. The apex of the bends from the first bend 111 to the last bend increases or decreases sequentially. This configuration allows for the creation of a bend structure that is not symmetrical about the longitudinal axis of the pull-out section 2. This bend structure configuration allows for a larger winding radius while maintaining a smaller loosening section 1, avoiding excessive damage to the tissues during instrument insertion and removal, and ensuring a larger winding radius, thus maximizing the loosening range of the loosening section 1. The bending structures facing the same direction are identical. The two intersecting segments constituting the bending structure are the first segment and the second segment, respectively. The first segment and the second segment have different lengths, and the bisector of the angle of the bend is perpendicular to the axis of the pull-out part 2. This setting can create an effective bending structure that deviates from the axis of the pull-out part 2. In addition, the identical setting of each bending structure can ensure that each bending structure applies the same winding force to the part 1 to be loosened during rotation, avoiding differences in the loosening effect on different parts due to different bending forces, which would ultimately affect the overall loosening effect.

[0059] The bending structure is formed by bending a round rod, with a diameter ranging from 2-4 mm, preferably 2.3-3 mm. The diameter of the straight rod in the pull-out section 2 ranges from 2-5 mm. This dimensional setting ensures that the entire structure has effective rotational winding strength and will not cause excessive damage to the skin upon insertion. Furthermore, the size of the pull-out section 2 gradually decreases from the end of the operating handle 3 to the end of the loosening section 1, with the diameter at the smallest position being the same as the diameter of the loosening section 1. This design improves the loosening strength of the entire loosening instrument.

[0060] refer to Figures 1-6A guide section, shaped like a frustum 121, is positioned at the front end of the release section 1. The outer diameter of the guide section gradually increases from front to back, with the front end being furthest from the pull section 2 and the rear end being closer to it. A dome structure 122 is located at the end of the frustum 121, and the central axis of the guide section is parallel to the central axis of the pull section 2. A bulging annular protrusion 123 is located in the middle of the guide section to provide a undulating motion during the insertion and removal of the guide section, thus improving the release effect. This structural design effectively reduces frictional resistance to the tissue when the instrument enters, providing good guidance during entry into the body. More specifically, the inclination of the frustum 121 can be adjusted according to the difficulty of entering the release area and the thickness of the fascia. A higher inclination results in a sharper front end for areas with greater difficulty in entry, facilitating rapid and accurate entry into the target area while reducing pressure and damage to surrounding tissues. The surface of the guide section is smoothed to further reduce friction with the tissue during entry, improving the smoothness of the operation. In a specific embodiment, the end of the dome structure 122 and the frustum structure 121 are connected by a smooth transition to ensure no sharp edges and prevent tissue scratches. Furthermore, the guide portion is made of the same material as the release portion 1, possessing good biocompatibility and mechanical strength, ensuring no deformation or damage during insertion and operation. The overall structure is safe and reliable, suitable for various complex release surgery scenarios.

[0061] refer to Figure 1 and Figure 3 All the bending structures are located in the same plane and are arranged sequentially along the axis of the pull-out part 2. This layout not only facilitates processing and manufacturing, but also ensures that each bending structure works synchronously during rotation, thereby improving the overall loosening efficiency.

[0062] At least two bending structures are provided in each direction; and the number of bending structures in each direction is the same. This arrangement can ensure that a stable winding force is formed during winding, avoid the risk of deformation of the loosening part 1 due to the imbalance of winding force in a single direction, and shorten the service life of the instrument.

[0063] Two adjacent bending structures facing different directions form an S-bend structure 13. Each loosening section 1 contains at least two S-bend structures 13. The longitudinal distance between the vertices of the two bends of each S-bend structure 13 ranges from 3 to 8 mm, and the lateral distance between each S-bend ranges from 6 to 10 mm. This arrangement can ensure the winding strength without creating a large cut during the entry and exit process.

[0064] The number of S-bend structures 13 and the number of interval segments 131 of the S-bend structures 13 are determined according to the required longitudinal distance of the loosening area. It should be noted that the longitudinal direction is consistent with the direction of the loosening needle's entry path, and the transverse direction is perpendicular to the direction of the loosening needle's entry path. Transverse loosening is achieved through rotational winding, while longitudinal loosening is achieved through multiple S-bend structures 13 individually, and also through pull-back. Specifically, the longitudinal distance of the loosening section 1 is increased by increasing the distance between the interval segments 131 of adjacent S-bend structures 13 to improve the overall longitudinal loosening range. For loosening areas with shorter longitudinal sections, continuous S-bend structures 13 can be used to improve operational flexibility and reduce interference with surrounding tissues. Furthermore, the interval segments 131 between the S-bend structures 13 are adjusted according to actual needs to ensure uniform force distribution during loosening, improving the stability and safety of instrument operation. By rationally configuring the density and arrangement of the S-bend structures 13, not only is the overall adaptability and maneuverability of the instrument improved, but the problem of local stress concentration caused by uneven structural force is also effectively reduced, thereby significantly improving the service life and reliability of the instrument. In practical implementation, the bending angle of the S-bend structure 13 can be controlled between 80 and 110 degrees according to actual needs, ensuring that the instrument maintains sufficient support during bending without causing excessive pressure on surrounding tissues. The design of the bending angle balances operational flexibility and structural stability, allowing the instrument to adapt more smoothly to complex anatomical environments during insertion and action. Simultaneously, the overall size and proportions of the S-bend structure 13 have been optimized, enabling efficient release operations within limited space, significantly improving the convenience and safety of clinical applications.

[0065] refer to Figure 5 and Figure 6 For areas with low fascial density requiring less force for rotation and wrapping, two S-bend structures 13 are used, with a distance greater than 1 cm between them; the specific distance is 1 cm, 2 cm, or 3 cm depending on the size of the area to be released. This structure allows for the release of all fascia in the longitudinal direction of the area corresponding to the two S-bend structures 13 using only the S-bend structures 13 at both ends. Then, a pull-back is used to further release the fascia in both directions. This method not only improves operational efficiency but also reduces tissue trauma caused by repeated instrument insertions.

[0066] refer to Figure 3 and Figure 4For situations requiring extensive release in both the lateral and longitudinal directions, such as the occipital region and areas with scarring on the skin surface, small-scale release is insufficient for effective stimulation. Therefore, a greater release is needed in both directions, requiring stronger lateral wrapping force and a wider longitudinal reach. To address this, three S-bend structures 13 with intervals of 1314-6mm are incorporated. Every two S-bend structures 13 are connected by a short connecting rod parallel to the longitudinal axis of the pull-out section 2. The pull-out section 2 is 10cm long; its specific dimensions can be controlled between 8-12cm. This arrangement of three S-bend structures 13 with intervals of 131 ensures that during lateral release, the three S-bends work together to create a strong wrapping force, ensuring better fascia wrapping around the release section 1, resulting in a better lateral release effect. Furthermore, the 1315-8mm intervals between the S-bends expand the longitudinal release range, ultimately leading to a more thorough and comprehensive release effect in both directions. Ultimately, due to the strong loosening force, it can loosen adhesions that are difficult to loosen. Because the overall length of the area to be loosened is relatively small, there are requirements for the length of the entire loosening needle. The reasonable distance between the loosening part 1 and the pulling part 2 of the three S-bend structures 13 mentioned above can ensure that the effects of winding, rotating and pulling loosening are achieved without compromising the overall length.

[0067] refer to Figure 1 and Figure 2 When releasing the sacroiliac joint region, two continuous S-curve structures 13 are designed without an intermediate segment 131. During use, the releasing needle is inserted between the joints, and continuous rotation creates a large rotational hole, thereby releasing the periosteum. Because the rotational hole is large, it achieves a good decompression effect. Furthermore, during pull-back, the two S-curve structures 13 create two vibrational stimulations on the bone surface, further enhancing the release effect.

[0068] refer to Figure 7 and Figure 8The operating handle 3 is implemented as follows: it includes a grip portion 31, a connecting portion 32, and a blocking portion 33. The grip portion 31 is arranged parallel to the longitudinal axis of the pull-out portion 2. The first end of the connecting portion 32 is connected to the pull-out portion 2, and the other end is connected to the first end of the grip portion 31; the connecting portion 32 is used to maintain a distance greater than 15mm between the longitudinal axis of the grip portion 31 and the pull-out portion 2 at a distance 131. The blocking portion 33 is connected to the second end of the grip portion 31 and is used to prevent the fingers gripping the grip portion 31 from disengaging from it during a rapid pull-back operation, thus preventing the rapid pull-back action from being completed. The operating handle 3 is integrally formed from the same material, but the materials of the operating handle 3 and the pull-out portion 2 are different. Specifically, the pull-out portion 2 and the release portion 1 are made of materials with higher density and toughness, while the operating handle 3 is made of a lightweight material. The operating handle 3 is a plate-shaped structure with a thickness greater than or equal to 4mm; this design balances the strength of the front-end material without significantly increasing the weight. The above-mentioned operating handle configuration ensures that a wheel-like structure is constructed during the rotation and winding operation, guaranteeing the rotation and winding operation. The blocking part 33 ensures that during the rapid pull-back operation, when the operating handle 3 encounters significant pull-back resistance, the hand separates from the operating handle 3, ensuring the effectiveness of the rapid pull-back action and thus ensuring the smooth completion of the loosening action.

[0069] refer to Figure 7 The connecting part 32 includes an arc-shaped structure 321 with a radius of 90 degrees and a radius of not less than 2 cm. This design ensures the distance between the grip part 31 and the pull-out part 2, guaranteeing effortless operation during rotation and winding. Furthermore, the arc-shaped structure 321 ensures comfortable gripping. The arc-shaped structure 321 is connected to a setting part 322, which extends perpendicular to the grip part 31. The setting part 322 is thicker than the arc-shaped structure 321. This design ensures that the pull-out part 2 can effectively extend into the connecting part 32 to form a stable assembly. Furthermore, the setting part 322 has an inverted triangular structure, that is, a structure that tapers inward from the end connected to the arc-shaped structure 321 to the other end; the pull-out part 2 is set near the vertex of the inverted triangle and on the angle bisector of the vertex. This setting can satisfy the balance of force during use, and can also maximize the distance between the grip part 31 and the pull-out part 2, minimize the force required for rotation and winding, and ensure the continuity of the entire operation.

[0070] refer to Figure 7 and Figure 8The blocking part 33 extends symmetrically from the second end of the holding part 31, and the distance from the end of the protruding part to the holding part 31 is less than or equal to 8mm, selected as 5mm; the blocking part 33 has curvature, and in cross-sectional view, the outer surface of the blocking part 33 is an arc-shaped surface; and the distance between the blocking part 33 and the holding part 31 in the vertical direction is less than or equal to 30mm; this setting can ensure that the blocking part 33 can be selected in the palm of the hand during the rotation and winding operation, without causing discomfort to the operator.

[0071] The arc-shaped connecting part 32, the grip part 31, and the lower protruding part of the blocking part 33 form a gripping space, with the maximum horizontal distance of the gripping space being less than or equal to 12cm. This design ensures that an adult can place their hand in the gripping space and can also pinch the setting part 322 with their thumb and index finger, place their middle finger and thumb in the gripping space, and place their ring finger on the inside of the blocking part 33 and their little finger on the outside of the blocking part 33. The above gripping method is one gripping method. When gripping, the user can choose a suitable gripping method according to the size of their hand. This size setting is a solution that meets the needs of most users.

[0072] The grip 31 includes an arc-shaped protrusion to ensure a comfortable grip. Furthermore, the entire edge of the operating handle 3 is blunted. This design ensures smooth rotation during winding and also guarantees the operator's comfort.

[0073] The symmetrical plane of the operating handle 3 is perpendicular to the plane where the bending structure is located. This setting ensures that during a rapid pull-back operation, the bending structure pulls back in its widest position on the horizontal plane, while the operating handle 3 is on the vertical plane. This combination ensures smooth and efficient pulling force and also optimizes the loosening effect.

[0074] refer to Figure 9 and Figure 10Because the material of the pull-out part 2 is different from that of the operating handle 3, the pull-out part 2 is assembled with the setting part 322. To ensure the stability of their positions after assembly, a assembly part larger than the pull-out part 2 is connected to the rear end of the pull-out part 2. An annular groove 21 for assembly is provided on the assembly part, and a rod 22 is placed inside the groove. Inclined assembly holes 3221 are provided on both sides of the setting part 322. An assembly rod 323 is inserted into the annular groove 21 through the assembly hole 3221. A drawer is also provided in the middle of the setting part 322. The pull part 2 is inserted into the second combination hole 3222; the width of the annular groove 21 is smaller than the diameter of the combination rod 323; by hammering the combination rod 323 into the annular groove 21 and making it tightly contact the rod 22 inside the groove, the rod 22 inside the groove can be slightly deformed when hammered in. This inclined setting can prevent the rotation of the pull rod after assembly. Because the size of the annular groove 21 is small, it can also prevent the horizontal movement of the pull part 2, ensuring the stability of the pull part 2 and the operating handle 3 after assembly, and ensuring that there will be no loosening or falling off during rotation and pulling. This combination structure is fixed by the tight fit between the combination rod 323 and the annular groove 21 during assembly, and will not be displaced or rotated due to external force during use, further improving the overall reliability and safety of operation. In addition, the fit between the combination rod 323 and the annular groove 21 also has good fatigue resistance and can withstand long-term frequent operation without failure. Meanwhile, the structure is easy to assemble. Simply tap the combination rod 323 into the annular groove 21 in the inclined direction to complete the fixation. No additional screws or other fasteners are required, which simplifies the assembly process and reduces production costs.

[0075] refer to Figures 11-12 A release device with a single-direction bending structure is provided only based on the implementation of the operating handle 3. Combining the operating handle 3 with the release device having a single-direction bending structure greatly improves the ease of operation of the release device. The corresponding guide section can be referenced... Figure 11 Set the annular protruding structure 123, refer to Figure 12 Alternatively, the annular protrusion structure 123 can be omitted, and the selection can be made based on the density of the tissue at the loosening location.

[0076] refer to Figure 13In use, first construct a surgical incision, then insert the releasing part 1 to the location requiring release, ensuring that the pulling part 2 has at least 3cm of space inside the subcutaneous tissue of the surgical incision. Next, rotate the operating handle. The rotation of the handle causes the bending structure of the releasing part 1 to rotate, causing some fascia to wrap around the outside of the bending structure. This rotational wrapping achieves the first step of release, releasing the fascia in one direction. Once the fascia is wrapped around the releasing part 1, quickly pull the releasing part 1 outwards. This pulls the fascia wrapped around the outside of the bending structure outwards, pulling it in a second direction (different from the wrapping direction), thus releasing the fascia in a larger area. Finally, after withdrawing a certain distance, the wrapping force of the fascia in the releasing part 1 will be less than the force required for fascia repositioning. At this point, the fascia will detach from the bending structure of the releasing part 1 and essentially return to its original position. By repeatedly performing the wrapping and pulling motions, the areas that need to be loosened are effectively released. When it is necessary to construct a trauma, a trauma can be constructed that activates the whole body for repair through local activation.
