Description

Technical Field

[0001] The invention relates to the technical field of postoperative care, in particular to a pair of elastic shorts used after surgery. Background Art

[0002] The hip bone is a bone in the human waist, with two bones on the left and right. It is easy for the elderly to suffer hip fractures, and the main means of treatment is surgery. After the operation, in order to prevent wound bleeding and re-injury of the hip bone, patients are usually cared for by wearing elastic abdominal belts or elastic shorts and trousers.

[0003] For example, the utility model patent with application number CN202223168855.4, publication number CN218961128U, and name “A trouser-type hip belt” discloses “a trouser-type hip belt, the shape of which is a shorts with openings at the buttocks and crotch; it includes a cylindrical upper part surrounding the hips and a forked lower part for embracing the left and right legs respectively; a continuous opening is provided in the lower part from the inner middle part of the left leg to the inner middle part of the right leg, and buckles are provided on both sides of the opening; elastic bands for compression and hemostasis are provided on both sides of the hip belt from the waist to the legs”. After the trouser-type hip belt is put on with the buckles, the elastic force of the elastic band is used to apply pressure to the hip position after surgery to prevent bleeding from the hip wound after surgery.

[0004] Although the trouser-type hip belt provided by the above patent can apply pressure to the hip position after surgery by utilizing the elastic force of the elastic band to prevent wound bleeding, it has at least the following disadvantages in actual operation:

[0005] As is well known, when wearing a pants-type hip belt, sufficient squeezing pressure must be provided for the postoperative hip belt position in order to prevent bleeding from the postoperative hip wound and to prevent further damage to the hip bone. However, in the prior art, once the pants-type hip belt is put on the patient, the squeezing pressure of the elastic band on the postoperative hip position will be locked, that is, the pressure value of the elastic band squeezing the hip position cannot be fine-tuned after the patient has put on the pants-type hip belt. Based on this, when the pressure value on the hip position is insufficient after the pants-type hip belt is put on, the prior art can only be adjusted by unfastening the connection (such as the buckle) and putting it on again. The pressure is increased in this way, and the operation is repeated until the squeezing force on the hip position after surgery reaches the required force. However, the amplitude of the untying and re-wearing movements is large, and when the connection is untied, the squeezing force originally applied to the patient's hip position after surgery will instantly disappear to zero, and when the patient is put on again, the squeezing force applied to the patient's hip position after surgery will instantly increase. The squeezing force applied to the hip position after surgery is greatly reduced and increased. Based on the above actions, it is very easy to cause bleeding and re-injury to the patient's hip position after surgery, and the risk is relatively high. It can be seen that the method of pressurizing the patient's hip position after surgery needs to be improved urgently. Summary of the Invention

[0006] The purpose of the present invention is to provide a postoperative elastic shorts to solve the above-mentioned deficiencies in the prior art.

[0007] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a pair of elastic shorts for postoperative use, comprising:

[0008] An elastic hip belt, used to compress the patient's hip position after surgery, comprising two separate ends, the two ends of the elastic hip belt being staggered with the patient's hip position after surgery;

[0009] A connecting device comprising a detachably connected left mechanism and a right mechanism, wherein the left mechanism is connected to one end of the elastic hip belt, and the right mechanism is connected to the other end of the elastic hip belt;

[0010] The left mechanism includes a rotating rod for retracting the elastic hip belt, which is elastically connected to the right mechanism so that the rotating rod can rotate unidirectionally in the direction of tightening the elastic hip belt. The rotating rod is rotated to retract the elastic hip belt to apply pressure to the patient's hip position after surgery.

[0011] The above-mentioned postoperative elastic shorts also include trouser legs connected below the elastic hip belt, the trouser legs are put on the legs corresponding to the postoperative hip positions of the patient, and the connecting device is located at the hip position that has not been operated on.

[0012] In the above-mentioned post-operative elastic shorts, the top opening of the trouser legs is divided into an inner half circle and an outer half circle, and the inner half circle of the top opening of the trouser legs is not connected to the elastic hip belt.

[0013] The above-mentioned postoperative stretch shorts have inner sides of the trouser legs cut open so that the trouser legs have two separated free ends, and the two free ends of the trouser legs are bonded together by Velcro.

[0014] The above-mentioned postoperative elastic shorts, the left mechanism also includes a support frame, the rotating rod is rotatably set on the support frame, one end of the elastic hip belt is fixedly sleeved on the rotating rod, and the rotating rod is fixed with two gears arranged along its axial direction. The right mechanism includes two limit blocks corresponding to the two gears one by one, the limit blocks are elastically slidably set and one end is provided with a sharp angle, the pointed end of the limit block is plugged into the tooth groove of the corresponding gear to limit the gear in one direction.

[0015] The above-mentioned postoperative elastic shorts, the front side surface of the limit block includes a first inclined surface located at the end of the limit block, and the rear side surface of the limit block includes a plane, the direction from the first inclined surface to the plane is the direction of the rotating rod to reel in the elastic hip belt, when the pointed end of the limit block is inserted into the tooth groove of the gear, the end of the tooth surface located on the front side of the limit block slides and abuts against the first inclined surface so that the gear can rotate in the direction of reeling in the elastic hip belt, and the tooth surface located on the rear side of the limit block fits with the plane so that the gear cannot rotate in the direction of releasing the elastic hip belt.

[0016] In the above-mentioned postoperative elastic shorts, the rear side surface of the limit block also includes a second inclined surface, which is located between the first inclined surface and the plane. The first inclined surface and the second inclined surface are arranged relative to each other to form a sharp angle of the limit block. When the limit block is slid away from the gear until the plane and the tooth surface are offset, the second inclined surface slides and abuts against the end of the tooth surface located on the rear side of the limit block so that the gear can rotate in the direction of releasing the elastic hip belt.

[0017] In the above-mentioned postoperative elastic shorts, the rotational force of the gear in the direction of releasing the elastic hip belt is provided by the elastic force of the elastic hip belt. When the end of the tooth surface located on the rear side of the limit block abuts against the second inclined surface, the rotational force of the gear in the direction of releasing the elastic hip belt drives the limit block to slide elastically in the direction away from the gear to rotate the gear, thereby releasing the rolled elastic hip belt to reduce the squeezing force on the patient's hip position after surgery.

[0018] The above-mentioned postoperative elastic shorts, the left mechanism also includes two groups of blocking doors arranged on the support frame, the two groups of blocking doors are respectively located on the upper and lower sides of the support frame and correspond one-to-one to the two gears, each group of the blocking doors includes two relatively arranged revolving doors, the revolving doors are elastically rotatably connected to the support frame, in the initial state, the two revolving doors in each group of the blocking doors abut against each other to lock the right mechanism between the gear and the blocking door, at this time the limit block is inserted in the tooth groove of the corresponding gear.

[0019] In the above-mentioned postoperative elastic shorts, the two revolving doors in each group of the blocking doors can elastically rotate toward the direction of the gear when they are in contact with each other, so that the right mechanism can be pushed open from the outside and pass through the two revolving doors.

[0020] Beneficial effect: In the above technical solution, the present invention provides a postoperative elastic shorts, which designs the elastic hip belt into two separate ends, and the two separate ends are respectively connected to the left mechanism and the right mechanism of the connecting device, and the left mechanism and the right mechanism are detachably connected, so that the two separate ends of the elastic hip belt can be connected and untied, and the elastic hip belt can be worn when the two separate ends are connected. At the same time, the rotating rod in the left mechanism can retract the elastic hip belt, and under the action of the right mechanism, when the rotating rod is elastically engaged with the right mechanism, it can rotate unidirectionally in the direction of tightening the elastic hip belt, but cannot rotate in the opposite direction, so that the rotating rod can stop and lock when retracting the elastic hip belt, and the more elastic hip belts are retracted by the rotating rod, the greater the squeezing force of the elastic hip belt on the patient's hip position after surgery, until the required pressure value is reached. Therefore, compared with the prior art, when the elastic shorts are worn on the patient, the present invention can achieve pressurization of the patient's hip position after surgery without untying the elastic hip belt, only by rotating the rotating rod to retract the elastic hip belt. The operation amplitude is small, and the squeezing force will not disappear during the pressurization process. The pressurization is gradual and more stable, and it is not easy to cause bleeding and re-injury to the patient's hip position after surgery, which can effectively solve the shortcomings of the prior art.

DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] like Figure 1-13As shown, an embodiment of the present invention provides a postoperative elastic shorts, comprising:

[0039] An elastic hip belt 1 is used to compress the patient's hip position after surgery, and comprises two separate ends, the two ends of the elastic hip belt 1 being staggered with the patient's hip position after surgery;

[0040] The connecting device 5 includes a detachably connected left mechanism and a right mechanism, wherein the left mechanism is connected to one end of the elastic hip belt 1 and the right mechanism is connected to the other end of the elastic hip belt 1;

[0041] The left mechanism includes a rotating rod 7 for retracting the elastic hip belt 1. The rotating rod 7 is elastically connected to the right mechanism so that the rotating rod 7 can rotate unidirectionally in the direction of tightening the elastic hip belt 1. Rotating the rotating rod 7 retracts the elastic hip belt 1 to apply pressure to the patient's hip position after surgery.

[0042] The postoperative stretch shorts provided in this embodiment are used for postoperative care of patients undergoing hip surgery, providing safety protection for the hip area where surgery is performed. Terms related to direction and position, such as "upper," "lower," "left," "right," "front," and "back," are used in this embodiment with reference to the accompanying drawings. Specifically, during hip surgery, patients typically only undergo surgery on one hip, so the stretch shorts provided in this embodiment only need to ensure effective pressure on the hip area where surgery is performed. Among them, the elastic hip belt 1 is a belt-like structure with two separate ends. When the two separate ends are connected, the elastic hip belt 1 can be worn on the patient's hip position, and when the two separate ends are untied, the elastic hip belt 1 can be taken off. The two ends of the elastic hip belt 1 are staggered from the patient's postoperative hip position. When the two separate ends are connected, the patient's hip position for surgery will not be touched, making it safer when wearing the elastic hip belt 1. At the same time, the patient's postoperative hip position can be elastically squeezed by the elastic hip belt 1 without contacting the connecting device 5 (the squeezing of the hip position by the elastic hip belt 1 is gentler than the squeezing of the hip position by the connecting device 5), making the patient more comfortable. The connecting device 5 includes a detachably connected left and right mechanism. The left mechanism is connected to one end of the elastic hip belt 1, and the right mechanism is connected to the other end of the elastic hip belt 1. When the left and right mechanisms are connected, the two separated ends of the elastic hip belt 1 are connected, thereby enabling the elastic hip belt 1 to be worn. When the left and right mechanisms are separated, the two separated ends of the elastic hip belt 1 are separated, thereby enabling the elastic hip belt 1 to be removed. When the left and right mechanisms are connected, the elastic force of the elastic hip belt 1 exerts an outward pulling force on the left and right mechanisms, thereby firmly connecting the left and right mechanisms.

[0043] The left mechanism includes a rotatable rotating rod 7, which is fixedly connected to one end of the elastic hip belt 1. When the rotating rod 7 is rotated, the elastic hip belt 1 can be retracted and released. When the elastic hip belt 1 is retracted, the elastic hip belt 1 can increase the compressive force of the elastic hip belt 1 on the patient's hip position after surgery, and when the elastic hip belt 1 is released, the elastic hip belt 1 can reduce the compressive force of the elastic hip belt 1 on the patient's hip position after surgery. The rotating rod 7 is elastically engaged with the right mechanism, so that when the rotating rod 7 is elastically engaged with the right mechanism, the rotating rod 7 can rotate unidirectionally in the direction of tightening the elastic hip belt 1, but cannot rotate in the opposite direction. Therefore, the rotating rod 7 can continuously retract the elastic hip belt 1 to continuously increase the pressure on the patient's hip position after surgery. When the rotating rod 7 is not rotated, the elastic force of the elastic hip belt 1 can immediately lock the rotating rod 7 to maintain the compressive force of the elastic hip belt 1 on the patient's hip position after surgery, thus achieving an instant stop and lock effect. The operation of rotating the rotating rod 7 is performed on the basis of wearing elastic shorts. It can be seen that when the rotating rod 7 is elastically engaged with the right mechanism, the elastic hip belt 1 can continuously increase the pressure on the patient's hip position after surgery by simply rotating the rotating rod 7 until the squeezing pressure on the patient's hip position after surgery reaches the required level. There is no need to untie the elastic hip belt 1 during the entire process, and the squeezing pressure will not disappear to zero during the pressurization process. The squeezing pressure will not increase or decrease instantly, and the increase in squeezing pressure is more stable, and the movement amplitude is very small. It is not easy for the patient's hip position to bleed or be injured again after surgery, and the risk is extremely small. The working principle of the present invention is: the wearing is achieved by connecting the left mechanism and the right mechanism, at this time the rotating rod 7 is elastically clamped with the right mechanism, and the elastic hip belt 1 corresponds to the patient's postoperative hip position, and under the action of the elastic force of the elastic hip belt 1, the elastic hip belt 1 has a certain squeezing force on the patient's postoperative hip position. When the squeezing force received by the patient's postoperative hip position does not reach the required force, the rotating rod 7 is rotated counterclockwise to reel the elastic hip belt 1, thereby gradually increasing the squeezing force of the elastic hip belt 1 on the patient's postoperative hip position, and the rotating rod 7 can be immediately locked by the right mechanism when it is not rotating, so that it can be stopped and locked until the squeezing force of the elastic hip belt 1 on the patient's postoperative hip position reaches the required force. In the prior art, the postoperative hip position of the patient can only be pressurized by unfastening the connection (such as the buckle) and re-wearing the device, and this operation is repeated until the compression force on the postoperative hip position reaches the required force. However, the amplitude of the unfastening and re-wearing actions is large, and when the connection is unfastened, the compression force originally applied to the patient's postoperative hip position will instantly disappear to zero, and when the device is re-wearing, the compression force applied to the patient's postoperative hip position will instantly increase. The compression force applied to the postoperative hip position is greatly reduced and increased. Based on the above actions, it is very easy to cause bleeding and re-injury to the patient's postoperative hip position, which is a high risk.

[0044] In this embodiment, the elastic hip belt 1 is designed as two separate ends, which are respectively connected to the left mechanism and the right mechanism of the connecting device 5, and the left mechanism and the right mechanism are detachably connected, so that the two separate ends of the elastic hip belt 1 can be connected and untied, and the elastic hip belt 1 can be worn when the two separate ends are connected. At the same time, the rotating rod 7 in the left mechanism can reel in the elastic hip belt 1, and under the action of the right mechanism, when the rotating rod 7 is elastically engaged with the right mechanism, it can rotate unidirectionally in the direction of tightening the elastic hip belt 1, but cannot rotate in the opposite direction, so that the rotating rod 7 can stop and lock when reeling in the elastic hip belt 1. The more the rotating rod 7 reels in the elastic hip belt 1, the greater the squeezing force of the elastic hip belt 1 on the patient's hip position after surgery, until the required pressure value is reached. Therefore, compared with the prior art, when the elastic shorts are worn on the patient, the present invention can achieve pressurization of the patient's hip position after surgery without untying the elastic hip belt 1, only by rotating the rotating rod 7 to retract the elastic hip belt 1. The operation amplitude is small, and the squeezing force will not disappear during the pressurization process. The pressurization is gradual and more stable, and it is not easy to cause bleeding and re-injury to the patient's hip position after surgery, which can effectively solve the shortcomings of the prior art.

[0045] In this embodiment, the connecting device can not only connect the two separated ends of the elastic hip belt 1, but also adjust the squeezing pressure of the patient's hip position after surgery, and can achieve self-locking. Since the elastic hip belt 1 is rolled up by the rotating rod 7 to achieve pressure adjustment of the patient's hip position after surgery, the connecting device still has a large adjustment ability despite the limited size of the structure, which can greatly improve the applicability of elastic shorts to different patients.

[0046] In this embodiment, it also includes a trouser leg 2 connected to the bottom of the elastic hip belt 1. The top of the trouser leg 2 is integrally connected or sewn to the bottom of the elastic hip belt 1. The trouser leg 2 is put on the leg corresponding to the patient's postoperative hip position, so that the trouser leg 2 can play a role in stably squeezing the elastic hip belt 1 to the patient's postoperative hip position, preventing the elastic hip belt 1 and the patient's postoperative hip position from being misaligned up and down. The connecting device 5 is located at the hip position that has not undergone surgery. When the elastic hip belt 1 is worn, the connecting device 5 is located at the hip position that has not undergone surgery and fits with it, so that the connecting device 5 is not easy to slide up and down.

[0047] Among them, no trouser legs are set on the legs corresponding to the hip position of the patient who has not undergone surgery, that is, only one trouser leg 2 is set in this embodiment, avoiding interference with the connection of the two separated ends of the elastic hip belt 1 and the winding of the elastic hip belt 1 due to the setting of the trouser legs.

[0048] Furthermore, the top opening of the trouser leg 2 is divided into an inner half circle and an outer half circle. The inner half circle of the top opening of the trouser leg 2 is not connected to the elastic hip belt 1, and only the outer half circle of the top opening of the trouser leg 2 is connected to the elastic hip belt 1, so that when the elastic hip belt 1 is rolled up and tightened, the trouser leg of the trouser leg 2 will not be enlarged.

[0049] Furthermore, the inner side of the trouser leg 2 is cut open so that the trouser leg 2 has two separate free ends. Velcro 3 is sewn on the two free ends of the trouser leg 2, and the two free ends of the trouser leg 2 are bonded together by the Velcro 3. When wearing the elastic shorts, the Velcro 3 is opened to open the two free ends of the trouser leg 2, and the two ends of the elastic hip belt 1 are opened at the same time. The patient can stand or lie down. When the patient is standing, the elastic hip belt 1 is first wrapped around the patient's hip and the left and right mechanisms of the connecting device 5 are connected. Then, the trouser leg 2 is wrapped around the patient's thigh and the two free ends of the trouser leg 2 are bonded together by the Velcro 3. The elastic shorts can be put on. When the patient is lying down, the elastic hip belt 1 and the trouser leg 2 are unfolded and laid on the bed, and one end of the elastic hip belt 1 is passed under the patient's hip and one end of the trouser leg 2 is passed under the patient's thigh. Then, the left and right mechanisms of the connecting device 5 are connected. Finally, the Velcro 3 on the trouser leg 2 is bonded together. The elastic shorts can be put on. The above-mentioned wearing method does not require the patient to bend his legs and lift his feet, making it more convenient to wear and not prone to causing pain in the patient's hips. When pressure is required, the rotating rod 7 only needs to be rotated, which will not be described in detail.

[0050] In this embodiment, the left mechanism also includes a support frame 6, and a rotating rod 7 is rotatably set on the support frame 6. The outer side surface of the support frame 6 in the vertical direction is an arc surface 603 and fits the position of the patient's hip that has not undergone surgery. The support frame 6 includes two horizontal plates 601 that are respectively integrated at the top and bottom of the support frame 6. The rotating rod 7 is rotatably set between the two horizontal plates 601, and both ends of the rotating rod 7 extend to the outside of the support frame 6 and are fixedly installed with handles 702. By rotating the handle 702, the rotating rod 7 can be driven to rotate to realize the retraction of the elastic hip belt 1. One end of the elastic hip belt 1 is fixedly sleeved on the rotating rod 7, and the rotating rod 7 is fixed with two gears 701 arranged along its axial direction. The wheel 701 includes a plurality of tooth grooves, each of which has two tooth surfaces in the circumferential direction of the gear 701 (the "tooth surface" referred to below refers to the tooth surface of the gear 701 tooth groove). The right mechanism includes two limit blocks 8 corresponding to the two gears 701 one by one. The limit block 8 is elastically slidably arranged and has a sharp angle at one end. The sharp end of the limit block 8 is plugged into the tooth groove of the corresponding gear 701 (the plugging here means that the limit block 8 abuts against the two tooth surfaces of the tooth groove) to limit the gear 701 in one direction. At this time, under the action of the sharp angle of the limit block 8, the gear 701 can only rotate in the direction of winding the elastic hip belt 1, that is, the rotating rod 7 can only rotate in the direction of winding the elastic hip belt 1, and cannot rotate in the opposite direction.

[0051] Specifically, the front side surface of the limit block 8 includes a first inclined surface 801 located at the end of the limit block 8, and the first inclined surface 801 is inclined toward the end of the limit block 8 toward the inner side of the limit block 8, and the rear side surface of the limit block 8 includes a plane 803 (the direction in which the front side surface of the limit block 8 points to its rear side surface is the direction in which the rotating rod 7 reels the elastic hip belt 1), and the direction from the first inclined surface 801 to the plane 803 is the direction in which the rotating rod 7 reels the elastic hip belt 1. When the pointed end of the limit block 8 is inserted into the tooth groove of the gear 701, the end of the tooth surface located on the front side of the limit block 8 slides and abuts against the first inclined surface 801 so that the gear 701 can rotate in the direction of reeling in the elastic hip belt 1, and the tooth surface located on the rear side of the limit block 8 fits with the plane 803 so that the gear 701 cannot rotate in the direction of releasing the elastic hip belt 1 (i.e., the opposite direction of reeling in the elastic hip belt 1). When the lever 702 is in the unlocked position, the two gears 701 are rotated in a direction that allows the lever 702 to move in a reverse direction and the two gears 701 to move out of the unlocked position.

[0052] Furthermore, the rear side surface of the limit block 8 also includes a second inclined surface 802, which is located between the first inclined surface 801 and the plane 803. The first inclined surface 801 and the second inclined surface 802 are arranged relative to each other to form a sharp angle of the limit block 8. When the limit block 8 is inserted into the tooth groove of the gear 701, the second inclined surface 802 is located in the tooth groove and does not contact the tooth surface. When the limit block 8 is slid away from the gear 701 until the plane 803 is offset from the tooth surface, the second inclined surface 802 slides and abuts against the end of the tooth surface located on the rear side of the limit block 8 so that the gear 701 can rotate in the direction of releasing the elastic hip belt 1, so that the rolled elastic hip belt 1 is released from the rotating rod 7, thereby reducing the squeezing force of the elastic hip belt 1 on the patient's hip position after surgery. Specifically, when the elastic hip belt 1 exerts too much pressure on the patient's hip position after surgery, the elastic hip belt 1 also needs to be untied. It is only necessary to slide the limit block 8 in the direction away from the gear 701 until the plane 803 is staggered with the tooth surface. At this time, the limit block 8 unlocks the gear 701. When the handle 702 is rotated in the direction of releasing the elastic hip belt 1, the rotating rod 7 and the two gears 701 can be driven to rotate synchronously. The rotation of the gear 701 causes the end of the tooth surface located on the rear side of the limit block 8 to squeeze the second inclined surface 802 to push the limit block 8 toward It slides elastically in the direction away from the gear 701 until the limit block 8 slides out of the tooth groove, so that the limit block 8 is inserted into the original position in the next tooth groove again under the action of the elastic force (the plane 803 is staggered with the tooth surface, and the second inclined surface 802 slides and abuts against the end of the tooth surface located on the rear side of the limit block 8), thereby releasing the rolled elastic hip belt 1, so that the squeezing force of the elastic hip belt 1 on the patient's hip position after surgery is reduced, and in this way, the squeezing force on the patient's hip position after surgery is reduced to an appropriate force.

[0053] In this embodiment, the rotational force of the gear 701 in the direction of releasing the elastic hip belt 1 is provided by the elastic force of the elastic hip belt 1. Since the elastic hip belt 1 will be released only when the squeezing force of the elastic hip belt 1 on the hip position is large, the elastic force of the elastic hip belt 1 is large at this time. The elastic force of the elastic hip belt 1 applies a pulling force to the rotating rod 7, thereby providing the gear 701 with a rotational force in the direction of releasing the elastic hip belt 1. When the elastic sliding resistance of the limit block 8 is less than the rotational force of the gear 701 in the direction of releasing the elastic hip belt 1, the elastic force of the elastic hip belt 1 can be used to release the elastic hip belt 1. The gear 701 automatically rotates to push the stopper 8 out of the tooth groove, thereby releasing the wound elastic hip belt 1 and automatically reducing the pressure on the patient's hip after surgery. When the elastic sliding resistance of the stopper 8 is greater than the rotational force of the gear 701 rotating in the direction of releasing the elastic hip belt 1, the stopper 8 will not slide out of the tooth groove. At this time, the gear 701 stops rotating, locking the pressure of the elastic hip belt 1 on the patient's hip after surgery at a specific value. This prevents the pressure on the patient's hip from suddenly disappearing to zero, and achieves a smooth pressure reduction. That is, when the end of the tooth surface located on the rear side of the stopper 8 abuts the second inclined surface 802, the rotational force of the gear 701 in the direction of releasing the elastic hip belt 1 drives the stopper 8 to elastically slide away from the gear 701, causing the gear 701 to rotate, thereby releasing the wound elastic hip belt 1 and reducing the pressure on the patient's hip after surgery. Moreover, when the position where the end of the tooth surface located on the rear side of the limit block 8 abuts the second inclined surface 802 is different, the angle of rotation of the gear 701 will be different, so that the length of the released elastic hip belt 1 will be different, and the amount of reduction in the squeezing force on the patient's hip position after surgery will be different. It can be seen that the limit block 8 can play a role in setting the extent to which the squeezing force on the patient's hip position after surgery is reduced.

[0054] In this embodiment, the left mechanism also includes two groups of blocking doors arranged on the support frame 6, and the two groups of blocking doors are respectively located on the upper and lower sides of the support frame 6 and correspond one-to-one to the two gears 701. Each group of blocking doors includes two relatively arranged revolving doors 14, and the revolving doors 14 are elastically rotatably connected to the support frame 6. In the initial state, the two revolving doors 14 in each group of blocking doors abut against each other to lock the right mechanism between the gear 701 and the blocking door. At this time, the limit block 8 is inserted into the tooth groove of the corresponding gear 701. Specifically, a group of brackets 602 are fixedly provided on each of the two horizontal plates 601, one group of blocking doors is located between one group of brackets 602 and one of the horizontal plates 601, and the other group of blocking doors is located between the other group of brackets 602 and the other horizontal plate 601. A rotating shaft 1401 is rotatably inserted on each revolving door 14, and a torsion spring (not shown in the figure) is provided between the revolving door 14 and the rotating shaft 1401. The torsion spring is fixedly connected to the rotating shaft 1401 and is clamped to the revolving door 14 (the installation and use of the torsion spring are both existing technologies and will not be repeated here). The torsion force of the torsion spring is used to realize the elastic rotation of the revolving door 14 and the support frame 6. Under the action of the torsion force of the torsion spring, the two revolving doors 14 in each group of blocking doors abut against each other (the two revolving doors 14 block when they abut). The two revolving doors 14 in each set of blocking doors are stabilized in an abutting state. At this time, the two revolving doors 14 in each set of blocking doors cannot rotate in the direction away from the gear 701 (that is, the two revolving doors 14 cannot be opened in the direction away from the gear 701), thereby limiting one end of the right mechanism close to the revolving door 14, and the other end of the right mechanism is a limiting block 8. At this time, the limiting block 8 is inserted into the tooth groove of the gear 701, so that the end of the right mechanism away from the revolving door 14 is also limited, so that the right mechanism is locked, realizing the connection between the left mechanism and the right mechanism. At the same time, the gear 701 is also locked by the limiting block 8 and cannot rotate in the direction of releasing the elastic hip belt 1, thereby locking the squeezing force of the elastic hip belt 1 on the patient's hip position after surgery.

[0055] Among them, the cross-section of the revolving door 14 is L-shaped, so that the two revolving doors 14 in each group of blocking doors can elastically rotate toward the direction of the gear 701 when they are in abutment with each other (i.e., in a closed state), but cannot rotate in the direction away from the gear 701, so that the right mechanism can push the two revolving doors 14 in each group of blocking doors from the outside and rotate in the direction of the gear 701 until the right mechanism passes through the two revolving doors 14 in each group of blocking doors, and then the two revolving doors 14 in each group of blocking doors are re-adapted under the action of the torsion spring, so that the end of the right mechanism close to the two groups of blocking doors is limited by the two groups of blocking doors, and at the same time, the end of the right mechanism away from the blocking doors (i.e., the two limit blocks 8) is limited by the two gears 701, thereby realizing the locking of the right mechanism, so that the right mechanism is connected to the left mechanism.

[0056] In order to simultaneously realize the connection between the right mechanism and the left mechanism and the locking of the gear 701 by the right mechanism, in this embodiment, the right mechanism also includes two piston systems corresponding to the two limit blocks 8, and the piston system includes a cylinder body 12. The interior of the cylinder body 12 is provided with a first sealing chamber 1201 and a second sealing chamber 1202 that are connected to each other. The first sealing chamber 1201 and the second sealing chamber 1202 are filled with lubricating fluid 4. The first sealing chamber 1201 passes through the right end face of the cylinder body 12, and the second sealing ring 1202 passes through the left end face of the cylinder body 12. The diameter of the first sealing chamber 1201 is smaller than the diameter of the second sealing chamber 1202. The dynamic seal (to sliding seal) in the first sealing chamber 1201 is plugged with a first piston rod 1 1. The second piston rod 13 is dynamically sealed in the second sealing chamber 1202. The left side of the first piston rod 11 extends to the outside of the cylinder body 12 and is fixedly installed with a connecting disk 1101. A compression spring 10 is fixedly connected between the connecting disk 1101 and the corresponding limit block 8. The elastic force of the compression spring 10 is used to realize the elastic sliding of the limit block 8. At the same time, a cylinder 9 that is slidably inserted with the first piston rod 11 is fixedly installed on the limit block 8. A vent hole 901 is provided on the cylinder 9 to enable the first piston rod 11 to slide left and right in the cylinder 9, thereby realizing the left and right sliding of the limit block 8. The right end of the second piston rod 13 extends to the outside of the cylinder body 12 and abuts against the side surfaces of two revolving doors 14 that are in abutment with each other in a set of blocking doors.Specifically, when the right mechanism is connected to the left mechanism, first the hand applies a left force to the right mechanism to insert it into the left mechanism, and the pointed ends of the two limit blocks 8 in the right mechanism push the two revolving doors 14 in each set of blocking doors one by one, so that the two revolving doors 14 in each set of blocking doors open in the direction of the gear 701, and then the pointed ends of the two limit blocks 8 in the right mechanism are inserted into the tooth grooves of the two gears 701 one by one, and then the right mechanism continues to slide to make the first piston rod 11 slide to the right along the first sealing chamber 1201 to push the second piston rod 13 to slide to the right along the second sealing chamber 1202 until the connecting disk 1101 abuts against the left end surface of the cylinder body 12, and then the connecting disk 1101 pushes the compression spring 10 to continuously compress so that the first piston rod 11 is inserted into the innermost side of the cylinder body 9. The right mechanism passes through two groups of blocking doors. The two revolving doors 14 in each group of blocking doors are re-adapted under the action of the torsion force of the torsion spring. The elastic hip belt 1 is in a tensioned state under the pull of the right mechanism to generate a certain squeezing pressure on the patient's hip position after surgery. Then the force applied by the hand to the right mechanism is removed. At this time, under the push of the elastic force of the compression spring 10 and the pull of the elastic force of the elastic hip belt 1, the connecting plate 1101 and the cylinder body 12 are driven to slide to the right so that the right end of the second piston rod 13 abuts against the revolving door 14 in the abutting state to realize the limiting of the right end of the right mechanism by the blocking door. At the same time, the limit block 8 is inserted into the corresponding tooth groove and is limited by the gear 701 to realize the limiting of the left end of the right mechanism, and the gear 701 is limited by the inserted limit block 8, thereby realizing the connection between the left mechanism and the right mechanism and the locking of the gear 701 by the right mechanism.

[0057] Among them, in order to achieve the function of setting the degree to which the squeezing force on the patient's hip position after surgery is reduced without untying the elastic hip belt 1, in this embodiment, when the connecting disk 1101 is in contact with the left end face of the cylinder body 12, when the compression elastic force of the compression spring 10 is completely released, the vertical distance between the left end of the limiting block 8 and the right end of the second piston rod 13 is smaller than the minimum distance between the gear 701 and the revolving door 14. Since the diameter of the first sealing cavity 1201 is smaller than the diameter of the second sealing cavity 1202, when a force is applied to the cylinder body 12 to the right to drive When the blocking door generates a leftward thrust on the second piston rod 13, the sliding distance of the first piston rod 11 to the left will be greater than the sliding distance of the second piston rod 13 to the left, and the first piston rod 11 can drive the limit block 8 to move to the left (that is, toward the gear 701), so that the right end face of the second piston rod 13 can be abutted against the blocking door, so that the limit block 8 is gradually inserted into the tooth groove of the gear 701, so that the second inclined surface 802 reaches the end position of the tooth surface on the rear side of the limit block 8. In this process, the hand needs to apply a fixing force to the gear 701 or the handle 702 to prevent the elastic hip belt 1 from pulling the rotation The rod 7 rotates, and then the fixing force applied to the gear 701 or the handle 702 is removed. The pulling action of the elastic hip belt 1 can drive the rotating rod 7 to rotate in the direction of releasing the elastic hip belt 1, and then drive the gear 701 to rotate in the direction of releasing the elastic hip belt 1. During the rotation of the gear 701, the limit block 8 is pushed to the right to squeeze the compression spring 10 so that the limit block 8 is disengaged from the tooth groove of the gear 701, thereby releasing the elastic hip belt 1. When the rotation force of the gear 701 is no greater than the resistance of the limit block 8 sliding to the right, it stops rotating. At this time, the gear 701 is locked again by the limit block 8, so that The squeezing force of the elastic hip belt 1 on the patient's hip position after surgery is reduced to a specific value. When the depth of the limit block 8 inserted into the tooth groove is different, the force with which the gear 701 pushes the limit block 8 out of the tooth groove is different, thereby causing the gear 701 to rotate at a different angle, that is, the length of the released elastic hip belt 1 is different, and then when the gear 701 is locked again by the limit block 8, the squeezing force on the patient's hip position after surgery is different. Therefore, it is only necessary to control the depth of the limit block 8 inserted into the tooth groove to enable the limit block 8 to set the degree to which the squeezing force on the patient's hip position after surgery is reduced.

[0058] When it is necessary to reduce the squeezing force on the patient's hip after surgery, the operation steps are as follows: first, apply a leftward thrust to the two cylinders 12, so that the two limit blocks 8 squeeze the two gears 701, so that the connecting plate 1101 abuts against the left end surface of the cylinder 12, and at the same time compress the compression spring 10 to the limit state (such as Figure 10As shown), one hand then applies a fixing force to the gear 701 or the handle 702 to prevent it from rotating, and the other hand pushes the two cylinder bodies 12 to the right. At this time, the compression force of the compression spring 10 is gradually released to make the first piston rod 11 slide out of the cylinder body 9 continuously until the compression force of the compression spring 10 is completely released, and then the limit block 8 is disengaged from the tooth groove (as shown). Figure 11 As shown), the right end face of the second piston rod 13 abuts against the blocking door, so that the second piston rod 13 is subjected to a leftward extrusion force, causing the second piston rod 13 to slide to the left. The second piston rod 13 drives the first piston rod 11 to slide to the left through the lubricating fluid 4. The sliding length of the first piston rod 11 is greater than the length of the second piston rod 13, so that the two limit blocks 8 are gradually inserted into the corresponding tooth grooves. When the second inclined surface 802 reaches the end position of the tooth surface located at the rear side of the limit block 8 (as shown), the second inclined surface 802 reaches the end position of the tooth surface located at the rear side of the limit block 8 (as shown). Figure 12 As shown), and after the relative positions of the two are appropriate, the fixing force applied to the gear 701 or the handle 702 is removed. Finally, under the pulling action of the elastic hip belt 1, the rotating rod 7 rotates a certain angle in the direction of releasing the elastic hip belt 1 to release the elastic hip belt 1, thereby reducing the squeezing force on the patient's hip position after surgery to a certain value.

[0059] In this embodiment, an upper rod 18 is fixedly mounted on one cylinder 12, and a lower rod 19, located below the upper rod 18, is fixedly mounted on the other cylinder 12. By applying leftward and rightward forces to the upper and lower rods 18 and 19, leftward and rightward forces can be applied to both cylinders 12. Furthermore, an upper guide fork plate 604 and a lower guide fork plate 605 are fixedly mounted on the support frame 6. The upper rod 18 is slidably inserted into the upper guide fork plate 604, and the lower rod 19 is slidably inserted into the lower guide fork plate 605. This prevents the right mechanism from rotating or prying, thereby providing a stable locking effect on the gear 701.

[0060] Furthermore, the two cylinder bodies 12 are symmetrically arranged up and down, and a notch 1203 is provided at one end of the cylinder body 12 close to the blocking door. Each revolving door 14 includes a fixed semicircular protrusion 1402. When the two revolving doors 14 on each group of blocking doors abut against each other, the two semicircular protrusions 1402 are combined into a complete cylinder, and the end of the cylinder abuts against the right end face of the second piston rod 13. Under the action of the notch 1403, the outer surface of the cylinder abuts against the inner wall of the first sealing cavity 1201 so that the right mechanism is limited in the up and down directions by the two groups of blocking doors, thereby limiting the right mechanism in both the left and right directions and the up and down directions.

[0061] Furthermore, an upper sleeve 15 is fixedly mounted on one of the cylinder bodies 12, and a lower sleeve 16 which is coaxial and has the same diameter as the upper sleeve 15 is fixedly mounted on the other cylinder body 12. A connecting rod 17 is slidably inserted between the upper sleeve 15 and the lower sleeve 16. The elastic hip belt 1 is sleeved on the upper sleeve 15, the lower sleeve 16 and the connecting rod 17 to realize the connection between the elastic hip belt 1 and the right mechanism. A spring (not shown in the figure) is connected between the top end of the connecting rod 17 and the inner cavity of the upper sleeve 15 and between the bottom end of the connecting rod 17 and the inner cavity of the lower sleeve 16. Through the design of the above structure, the right mechanism and the left mechanism can be easily separated.

[0062] Specifically, by applying an inward force to the upper pull rod 18 and the lower pull rod 19 at the same time, the upper sleeve 15 and the lower sleeve 16 are moved closer to each other at the same time, and then the two cylinder bodies 12 are moved closer to each other. The two cylinder bodies 12 respectively drive the two limit blocks 8 and the two second piston rods 13 to move closer to separate the two limit blocks 8 from the two gears 701, and the two second piston rods 13 are separated from the two sets of blocking doors. Finally, the upper pull rod 18 and the lower pull rod 19 apply a force to the right to slide the right mechanism out of the left mechanism, so as to realize the separation of the right mechanism and the left mechanism.

[0063] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
