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] Further, the operation handle comprises a holding part, a connecting part and a blocking part.

[0019] The holding part is arranged in a direction parallel to the longitudinal axis of the pulling part.

[0020] The connecting part is connected to the first end of the pulling part and the first end of the holding part, and is used to realize a distance between the longitudinal axis of the holding part and the interval section of the pulling part greater than 15 mm.

[0021] The blocking part is connected to the second end of the holding part, and is used to block the fingers holding the holding part from being separated from the holding part when the quick pull operation is performed, so as to ensure the completion of the quick pull operation.

[0022] The operation handle is integrally formed and made of the same material, but the material of the operation handle is different from that of the pulling part. Specifically, the pulling part and the loosening part are made of a material with higher density and toughness, and the operation handle is made of a lightweight material. The operation handle is a plate-shaped structure with a thickness greater than or equal to 4 mm. This arrangement can balance the strength of the front-end material and will not have too much weight.

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

[0024] Further, the blocking part symmetrically extends from the second end of the holding part, the distance from the end of the extended part to the holding part is less than or equal to 8 mm, the blocking part has a bending degree, the outer side of the blocking part is an arc-shaped curved surface in cross-section, and the distance between the blocking part and the holding part in the vertical direction is less than or equal to 30 mm.

[0025] Further, the symmetry plane of the operation handle is perpendicular to the plane where the bending structure is located.

[0026] Further, the rear end of the pulling part is connected to a combined part larger than the pulling part, a combined annular groove is arranged on the combined part, and an inner rod is arranged in the annular groove. Inclined combination holes are arranged on both sides of the combined part, and a combination rod is arranged in the combination hole and inserted into the annular groove. The width of the annular groove is less than the diameter of the combination rod. By knocking the combination rod into the annular groove and tightly contacting the inner rod, the inner rod can be slightly deformed during knocking. Therefore, the inclined arrangement can avoid the rotation of the pulling rod after combination, because the size of the annular groove is small, so as to avoid the horizontal movement of the pulling part, ensure the stability of the pulling part and the operation handle after combination, and ensure that there is no loosening or falling phenomenon during rotation and pulling.

[0027] Technical effects

[0028] The setting and cooperation of the loosening part, the pulling part and the operating handle can ensure the loosening of the winding and pulling directions of the position to be loosened, so that the loosening range meets the demand. Of course, in order to avoid the influence of the bending structure on the surgical incision position, the control withdrawn moving 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, and the setting of the pulling part not less than 3cm can greatly avoid the influence of the irregular bending of the bending structure on the wound position and ensure that the whole loosening process is carried out under the skin within the surgical incision.

[0029] The distance from the vertex of the bending structure to the longitudinal axis of the pulling part is different, which can form a larger winding radius under the premise of a smaller loosening part, avoid too much damage to the passing tissue when the instrument enters and exits, and ensure a larger winding radius to maximize the loosening range of the loosening part.

[0030] The setting of the plurality of S-bending structures can ensure the balance of the force during the rotating winding operation and ensure the stability of the structure.

[0031] The different S-bending structures and interval sections for different loosening positions ensure sufficient rotating winding gripping force, so that the tissue is rotated to the loosening part, and the interval section increases the loosening in the longitudinal range.

[0032] The setting of the connecting part of the operating handle makes the pulling part and the holding part spaced apart by a certain distance to form a labor-saving structure, which effectively ensures the effective application of force during the rotating winding. BRIEF DESCRIPTION OF DRAWINGS

[0052] Reference Figures 1-6 A rotation-winding and pulling combined loosening device, comprising:

[0053] The loosening part 1 comprises opposite bending structures, each of which comprises at least two bending structures, one of which comprises two intersecting segments and a bend formed by the intersecting segments; that is, the bending structures are bent in two directions, and the two directions are opposite;

[0054] The pulling part 2 is a straight rod connected to the loosening part 1, and the length of the straight rod is greater than or equal to 3 cm, which is used to ensure sufficient movement distance when the pulling part 2 is withdrawn, and to ensure that the loosening part 1 is maintained inside the surgical incision during operation;

[0055] The operating handle 3 is connected to the pulling part 2, and is used to perform rotation and pulling operations outside the body to complete the rotation-winding loosening and withdrawal-pulling loosening of the loosening part 1, and finally ensure the loosening operation on the human body loosening area.

[0056] Specifically, the fascia includes deep fascia and superficial fascia, the deep fascia refers to the fascia above and below the muscle and the periosteum, and the superficial fascia refers to the fascia in the fat layer between the skin and the muscle; the instrument is mainly applied to the superficial fascia, and of course is also applied to the muscle layer. One of the purposes of the release is that the tissue itself has adhesion, and the problem of tissue adhesion is solved by release, and the second is to artificially construct a local trauma that the human body can withstand in the fascia layer, to start the whole body repair mechanism of the human body through the constructed local trauma, so that the repair of the local part activates the cell proliferation of other tissues in the whole body, so that the whole human body is in an activated repair state; the system includes the immune system, the nervous system, etc., so that the repair process releases some cytokines, which are controlled by the brain, so that the brain is in an excited state, and the whole body repair is completed. For example, the release and stimulation of the posterior thoracic spine can effectively stimulate the meridians and achieve the purpose of treating lung diseases. The anterior release and stimulation can also achieve the therapeutic effect of the posterior side.

[0057] Through the setting and cooperation of the release part 1, the pulling part 2 and the operating handle, the release in the two directions of winding and pulling of the position to be released can be ensured, so that the release range meets the demand; of course, in order to avoid the influence of the bending structure on the surgical incision position, the control withdrawal distance is not greater than the distance of the pulling part 2, so as to ensure that the bending structure will not be pulled out of the surgical incision in a single outward pulling, and the setting of the pulling part 2 not less than 3cm can greatly avoid the influence of the irregular bending of the bending structure on the wound position to cause the influence on the incision position, and ensure that the whole release process is carried out under the skin within the surgical incision.

[0058] Reference Figure 2 With Figure 4; the distance from the vertex of the bend of the plurality of bending structures pointing to the same direction to the longitudinal axis of the pulling part 2 is different; when there are more than 3 bending structures pointing to the same direction, the distance from the vertex of the bend of the bending structures pointing to the same direction to the longitudinal axis of the pulling part 2 is sequentially increased or decreased, which is specifically explained as follows: the bending structure pointing to the same direction closest to the pulling part 2 is defined as the first bending structure 111, and the second bending structure, the third bending structure 113, the fourth bending structure, and the like are sequentially defined; the vertex of the bend of the first bending structure 111 to the last bending structure is sequentially increased or sequentially decreased. By such a setting, a skewed bending structure that is not symmetrical to the longitudinal axis of the pulling part 2 can be constructed, and by such a setting of the bending structure, a larger winding radius can be formed under the premise of a smaller releasing part 1, avoiding excessive damage to the tissues passing through when the instrument enters and exits, and ensuring a larger winding radius, thereby maximizing the release range of the releasing part 1. The bending structures pointing to the same direction are the same bending structures, the two intersecting sections constituting the bending structure are the first section and the second section, the lengths of the first section and the second section are different, and the angle bisector of the bend of the bending structure is perpendicular to the axis of the pulling part 2. By such a setting, a bending structure that effectively deviates from the axis of the pulling part 2 can be constructed, and the same setting of each bending structure can ensure that each bending structure provides the same winding force to the releasing part 1 during rotation, thereby avoiding differences in the release effect of different parts caused by different bending forces, and ultimately affecting the overall release effect.

[0059] The bending structure is a structure formed by bending a round rod, the diameter of the round rod of the bending structure is 2-4 mm, and preferably 2.3-3 mm; the diameter of the straight rod of the pulling part 2 is 2-5 mm; such a size setting can ensure that the entire structure has effective rotation winding strength and will not cause excessive damage to the skin when entering. Further, the size of the pulling part 2 gradually decreases from the end of the operating handle 3 to the end of the releasing part 1, and the diameter at the smallest position is the same as the diameter of the releasing part 1. By such a way of setting, the release strength of the entire release instrument can be improved.

[0060] Reference Figures 1-6The front end of the loosening part 1 is provided with a guide part, which is a conical frustum structure 121, the outer diameter of which gradually increases from front to back, the front end is away from the pulling part 2, and the back end is close to the pulling part 2; a ball top structure 122 is arranged at the end of the conical frustum structure 121, and the central axis of the guide part is parallel to the central axis of the pulling part 2; a bulging annular protruding structure 123 is arranged in the middle of the guide part, which is used to provide a movement fluctuation during the guide part in and out operation, and improve the loosening effect. Through the arrangement of such structure, the frictional resistance to the tissue can be effectively reduced when the instrument enters, so as to play a good guiding role when entering the body. More specifically, the inclination of the conical frustum structure 121 can be set according to the difficulty of the loosening area entering and the thickness of the fascia. In the area with high difficulty, the inclination is high, and the front end of the guide part is sharper to quickly and accurately enter the target area, while reducing the compression and damage to the surrounding tissue. The surface of the guide part is treated to be smooth, which further reduces the friction between the tissue during the entering process and improves the smoothness of the operation. In a specific embodiment, the end of the ball top structure 122 and the conical frustum structure 121 are connected in a smooth transition, so as to ensure that there is no obvious edge and to prevent scratching the tissue. In addition, the material of the guide part is consistent with the loosening part 1, which has good biocompatibility and mechanical strength, so as to ensure that it is not deformed and damaged during the entering and operating process. The overall structure is safe and reliable, and is suitable for various complex loosening operation scenes.

[0061] Reference Figure 1 With Figure 3 All the bending structures are arranged in the same plane and arranged in sequence along the axis direction of the pulling part 2. Such layout not only facilitates processing and manufacturing, but also can ensure that the bending structures act synchronously during rotation operation, thereby improving the overall loosening efficiency.

[0062] At least two bending structures are arranged in each direction, and the number of bending structures in each direction is the same. Through such arrangement, stable winding force can be formed during winding, the deformation risk of the loosening part 1 caused by unbalanced winding force in a single direction is avoided, and the service life of the instrument is shortened.

[0063] Two adjacent bending structures with different directions are constructed into an S-bend structure 13, each loosening part 1 contains at least two S-bend structures 13, the longitudinal distance between the two bending vertices of each S-bend structure 13 ranges from 3 mm to 8 mm, and the transverse distance of each S-bend ranges from 6 mm to 10 mm. Such arrangement can ensure the winding strength and avoid forming a large incision during the in and out process.

[0064] The number of S-bend structures 13 and the interval sections 131 of the S-bend structures 13 are set according to the size of the longitudinal distance of the need-relaxing area. It should be noted that the longitudinal direction is consistent with the direction of the needle entering path, and the transverse direction is perpendicular to the needle entering path. The transverse direction is relaxed by rotation and winding, and the longitudinal direction is relaxed by multiple S-bend structures 13 respectively. The longitudinal distance of the relaxation part 1 is increased by increasing the distance between the interval sections 131 of the adjacent two S-bend structures 13, so as to improve the overall longitudinal relaxation range. For the relaxation area with a short longitudinal direction, the continuous S-bend structure 13 can be set to improve the operation flexibility and reduce the interference with the surrounding tissue. In addition, the interval sections 131 between the S-bend structures 13 are also adjusted according to the actual needs to ensure uniform stress during the relaxation process and improve the stability and safety of the instrument operation. By reasonably configuring the density and arrangement of the S-bend structures 13, not only the adaptability and controllability of the instrument as a whole are improved, but also the local stress concentration problem caused by uneven stress of the structure is effectively reduced, thereby greatly improving the service life and reliability of the instrument. In the specific implementation process, the bending angle of the S-bend structure 13 can be controlled between 80 to 110 according to the actual needs, so as to ensure that the instrument can maintain sufficient support force during bending and will not cause excessive compression to the surrounding tissue. The design of the bending angle takes into account the flexibility of operation and the stability of the structure, so that the instrument can more smoothly adapt to the complex anatomical environment during entry and action. At the same time, the overall size and proportion of the S-bend structure 13 are optimized to realize efficient relaxation operation in a limited space, thereby significantly improving the convenience and safety of clinical application.

[0065] Reference Figure 5 With Figure 6 For the relaxation area with low fascia tightness, the rotation winding needs less force, so two S-bend structures 13 are set, and the distance between the two S-bend structures 13 is greater than 1 cm. According to the size of the need-relaxing area, 1 cm, 2 cm, or 3 cm are selected. When this structure is used, only the S-bend structures 13 at both ends are used to realize the winding relaxation of all fasciae in the longitudinal direction of the corresponding need-relaxing area of the two S-bend structures 13, and then the two directions are relaxed again by pulling back. This way not only improves the operation efficiency, but also reduces the trauma to the tissue caused by multiple insertions of the instrument.

[0066] Reference Figure 3 With Figure 4; For the need to be in the transverse and longitudinal both need to be a larger range of relaxation, such as the posterior occipital and skin surface has scar area, small range of relaxation can not achieve effective relaxation stimulation, so need to be in the transverse and longitudinal have a larger relaxation, so the need for transverse winding force is stronger, the longitudinal range is larger, so set 3 interval 1314-6mm set S bend structure 13, every two S bend structure 13 through the connection of the pull part 2 longitudinal axis parallel connection; The length of the pull part 2 is 10cm; The specific size can be controlled in 8-12cm. The setting mode of the three S bend structures 13 set by the interval 131 can ensure that the three S bends cooperate to form a strong winding force when transverse relaxation, so that the fascia is better wound in the relaxation part 1, so that the transverse relaxation effect is better, and because the S bend interval 1315-8mm distance is set, the longitudinal relaxation range can also be expanded, so that the overall relaxation effect of the two directions is more sufficient and comprehensive. Finally, because the relaxation force is large, it can realize the relaxation of the difficult-to-relax adhesion tissue. Because the overall length of the area to be relaxed is small, the length of the whole relaxation needle is required, and the reasonable distance setting of the relaxation part 1 and the pull part 2 of the above three S bend structures 13 can ensure that the winding rotation and pulling relaxation effect is completed under the premise of small overall length.

[0067] Reference Figure 1 With Figure 2 , for the relaxation of sacroiliac joint area, set two continuous S bend structures 13, no interval 131 is set in the middle. When in use, the relaxation needle is sent into the joint, a larger rotating hole is formed by continuous rotation, so as to relax the periosteum. Because the rotating hole is larger, it has a good decompression effect, and when pulling back, because there are two S bend structures 13, the vibration stimulation of the bone surface is formed twice, further increasing the relaxation effect.

[0068] Reference Figure 7 With Figure 8; the operation handle 3 comprises a holding part 31, a connecting part 32 and a blocking part 33. The holding part 31 is arranged in parallel with the longitudinal axis of the pulling part 2. The connecting part 32 is connected to the pulling part 2 at one end and to the first end of the holding part 31 at the other end. The connecting part 32 is used to realize the distance between the longitudinal axis of the holding part 31 and the interval section 131 of the pulling part 2 greater than 15 mm. The blocking part 33 is connected to the second end of the holding part 31 and is used to prevent the fingers holding the holding part 31 from being separated from the holding part 31 during the quick pull operation, thereby ensuring the completion of the quick pull operation. The operation handle 3 is integrally formed and made of the same material, but the material of the operation handle 3 is different from that of the pulling part 2. Specifically, the pulling part 2 and the loosening part 1 are made of a material with higher density and toughness, while the operation handle 3 is made of a lightweight material. The operation handle 3 is a plate-shaped structure with a thickness greater than or equal to 4 mm. This arrangement can balance the strength of the front-end material and reduce the weight. The above-mentioned operation handle arrangement can ensure the construction of a labor-saving structure in the form of a wheel disc during the rotation and winding operation, ensuring the rotation and winding operation. The blocking part 33 can also ensure that the hand and the operation handle 3 are separated during the quick pull operation when the operation handle 3 is subjected to a large pull resistance, thereby ensuring the effectiveness of the quick pull operation and the smooth completion of the loosening operation.

[0069] Reference Figure 7 ; The connecting part 32 comprises an arc-shaped structure 321 with an arc angle of 90 degrees, and the radius of the arc-shaped structure 321 is not less than 2 cm. This arrangement can ensure the distance between the holding part 31 and the pulling part 2 and ensure the labor-saving effect during rotation and winding. In addition, the arc-shaped structure 321 can ensure the comfort during holding. Further, the arc-shaped structure 321 is connected to a setting part 322 extending in a direction perpendicular to the holding part 31. The thickness of the setting part 322 is greater than that of the arc-shaped structure 321. This arrangement can ensure that the pulling part 2 effectively extends into the connecting part 32 to form a stable combination. Further, the setting part 322 is a reverse triangular structure, i.e., a structure that is inwardly tapered from one end to the other end. The pulling part 2 is arranged near the apex of the reverse triangle and on the angle bisector of the top angle. This arrangement can balance the force during use, maximize the distance between the holding part 31 and the pulling part 2, minimize the force required during rotation and winding, and ensure the continuity of the entire operation.

[0070] Reference Figure 7 With Figure 8The blocking part 33 is symmetrically extended from the second end of the self-holding part 31, the end of the extended part is less than or equal to 8mm away from the holding part 31, and 5mm is selected; the blocking part 33 has a bending degree, and the outer side of the blocking part 33 is an arc-shaped curved surface in the cross-sectional view; and the perpendicular distance between the blocking part 33 and the holding part 31 is less than or equal to 30mm; such a setting can ensure that the blocking part 33 can be completed in the palm during the rotating winding operation, and the operator will not feel uncomfortable.

[0071] The arc-shaped connecting part 32 is extended from the holding part 31 and the lower end of the blocking part 33 to form a holding space, and the maximum horizontal distance of the holding space is less than or equal to 12cm; such a setting can ensure that an adult sets the hand in the holding space, and can also hold the setting part 322 by the thumb and the index finger, the middle finger and the thumb are set in the holding space, in addition, the ring finger is in contact with the inner side of the blocking part 33, and the little finger is on the outer side of the blocking part 33. The above holding method is a holding method, and the user can select a suitable holding method according to the size of his hand during specific holding. Such a size setting is a scheme that meets the needs of most users.

[0072] The holding part 31 includes an arc-shaped protrusion to ensure the comfort level during holding, and the edges of the entire operation handle 3 are further blunted. Such a setting can ensure smooth rotation during rotating winding, and also ensures the comfort level of the operator.

[0073] The symmetric surface of the operation handle 3 is perpendicular to the plane where the bending structure is located; such a setting can ensure that the bending structure is pulled back in the widest state in the horizontal plane position during the quick pull-back operation, and the operation handle 3 is in the vertical plane at the same time. Such a cooperation mode can ensure the smoothness and efficiency of the pulling force, and also makes the loosening effect best.

[0074] Reference Figure 9 With Figure 10;Because the material of the pulling part 2 is different from that of the operating handle 3, the pulling part 2 is combined with the setting part 322 in a combined state, and in order to ensure the stability of the positions of the two after combination, a combined part larger than the pulling part 2 at one end is connected to the rear end of the pulling part 2, the combined part is provided with a combined annular groove 21, and the annular groove 21 is provided with a groove-in-bar 22; the setting part 322 is provided with inclined combined holes one 3221 on both sides, the combined holes one 3221 are provided with a combined rod 323 inserted into the annular groove 21 through the combined holes; the setting part 322 is further provided with a combined hole two 3222 for insertion of the pulling part 2; the width of the annular groove 21 is smaller than the diameter of the combined rod 323; by knocking the combined rod 323 into the annular groove 21 and tightly contacting the groove-in-bar 22, the groove-in-bar 22 can be slightly deformed when being knocked in, so that the inclination can avoid rotation of the pulling rod after combination, because the size of the annular groove 21 is small, so as to avoid horizontal movement of the pulling part 2, ensure the stability of the pulling part 2 after combination with the operating handle 3, and ensure that there is no loosening or falling phenomenon in the rotation and pulling process. The combined structure is fixed by the close fit of the combined 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 reliability and safety of the overall operation. In addition, the combined rod 323 and the annular groove 21 have good fatigue resistance and can withstand long-term frequent operation without failure. At the same time, the structure is easy to operate during assembly, and only needs to knock the combined rod 323 into the annular groove 21 along the inclined direction to complete the fixation, without the need for additional screws or other fasteners, simplifying the assembly process and reducing production costs.

[0075] Reference Figures 11-12 Only a single direction setting a loose instrument with a bending structure is arranged on the basis of the embodiment of the operating handle 3. By combining the operating handle 3 with the single direction setting a loose instrument with a bending structure, the operation convenience of the single direction setting a loose instrument with a bending structure can be greatly improved. The corresponding guide part can refer to Figure 11 The annular protruding structure 123 is arranged, and the reference Figure 12 The annular protruding structure 123 can also not be arranged, and the selection is made according to the tightness of the loose position organization.

[0076] Reference Figure 13;When in use, first make a surgical incision, then send the release part 1 to the position where it needs to be released, so that the pulling part 2 has a distance of at least 3 cm to enter the subcutaneous position inside the surgical incision; then rotate the operating handle, the rotation of the operating handle drives the rotation of the bending structure of the release part 1, the rotation of the bending structure winds part of the fascia outside the bending structure, and the first step of the release action is realized by the rotating winding mode, this action realizes the release in one winding direction; when the fascia is wound to the release part 1, the release part 1 is pulled out quickly, so that the release part 1 pulls the fascia wound outside the bending structure outward, so as to pull the wound fascia in a second direction different from the winding direction, so that the fascia in the second direction is released, and the release range is larger. Finally, when withdrawn to a certain distance, the winding force of the fascia on the release part 1 will be less than the force of the fascia reset, at this time the fascia is released from the bending structure of the release part 1, and basically returns to the original position. Through the winding and pulling action repeatedly, the part that needs to be released is effectively released, and when a wound needs to be constructed, a wound that can repair the whole body through local activation can also be constructed.
