Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a skin and scar tensile stress detection device. Background Art

[0002] The skin is the largest organ covering the human body surface and in direct contact with the external environment. When the skin is affected by various types of injuries or diseases, scars will be formed. Due to the scars left on the skin caused by injuries, subsequent tensile stress detection of the scars is often required in situations such as evaluating scar healing, formulating treatment plans, and studying the pathophysiological mechanisms of scars. Anchor needles can accurately fix the detection device at specific positions on the skin scars, ensuring the accuracy and repeatability of the measurement points. However, the spacing between the anchor needles cannot be adjusted during use. The skin tension of different parts of the human body is different in the natural state and during movement. The skin tension changes greatly during movement at joint parts, while it is relatively small at the trunk part. Without being able to adjust the spacing between the anchor needles, it is difficult to accurately measure according to the actual skin tension conditions in different parts, and the measurement results may be distorted due to inappropriate spacing at special parts such as joints.

Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or selectively mutually exclusive embodiment with other embodiments.

[0028] Embodiment 1

[0029] Referring to Figures 1 - 7 , this is the first embodiment of the present invention. This embodiment provides a skin and scar tensile stress detection device. The skin and scar tensile stress detection device includes a main body assembly 100, a clutch assembly 200, and a limit assembly 300. The three cooperate to adjust the distance between the anchor needles.

[0030] The clutch assembly 200 includes a clutch member 201, which includes a threaded rod 201a, a sliding sleeve 201b, a connecting rod 201c, a first bevel gear 201d, a second bevel gear 201e, a sliding rod 201f, a fixed sleeve 201g, a turntable 201h, and a positioning frame 201i. The number of sliding sleeves 201b is four, all of which are sleeved on the outer side of the threaded rod 201a and are threadedly connected. The number of connecting rods 201c is two, both of which are arranged at one end of the threaded rod 201a. The number of first bevel gears 201d is two, both of which are arranged at one end of the connecting rod 201c. The number of second bevel gears 201e is two, both of which are engaged on one side of the first bevel gear 201d. The sliding rod 201f is arranged at one end of the first bevel gear 201d. The inner wall of the fixed sleeve 201g is provided with a fixing groove 201g-1, and the sliding rod 201f slides on the inner wall of the fixing groove 201g-1. The turntable 201h is arranged at one end of the fixed sleeve 201g, and the threaded rod 201a slides on the inner wall of the positioning frame 201i.

[0031] There are four anchor needles 102, with two in a group. A support ring is arranged on the outer side of the fixed sleeve 201g. The support ring is used to support the fixed sleeve 201g and is movably connected to it. The other end is fixed to the inner wall of the protective frame 202n. Knobs are arranged at one end of the threaded rod 201a. Driving grooves are opened on the inner wall of the protective frame 202n, and the sliding sleeve 201b slides in the driving grooves.

[0032] By sliding the sliding rod 201f along the inner wall of the fixed sleeve 201g, the distance adjustment between the two groups of anchor needles 102 can be adapted.

[0033] Guide grooves are provided on the threaded rods 201a. The sliding sleeves 201b are sleeved outside the threaded rods 201a. Guide blocks corresponding to the guide grooves are fixed inside the sliding sleeves 201b, and the guide grooves on the two threaded rods 201a are in opposite directions. When the distance between the anchor needles 102 needs to be adjusted, by rotating the sliding rod 201f, the sliding rod 201f rotates to squeeze the fixed groove 201g-1, causing the fixed sleeve 201g to rotate. The rotation of the fixed sleeve 201g drives the turntable 201h to rotate. The rotation of the sliding rod 201f drives the second bevel gear 201e to rotate. The rotation of the second bevel gear 201e meshes with the first bevel gear 201d, causing the first bevel gear 201d to rotate. The rotation of the first bevel gear 201d drives the connecting rod 201c to rotate. The connecting rod 201c drives the threaded rod 201a to rotate. The rotation of the threaded rod 201a can drive the guide groove to squeeze the guide block, causing the guide block to move. The movement of the guide block can drive the sliding sleeve 201b to move, so that the two sliding sleeves 201b move towards each other. By the movement of the sliding sleeve 201b, the two anchor needles 102 can be driven to move.

[0034] The limiting component 300 is arranged on the top of the turntable 201h and includes a limiting member 301, which includes a moving rod 301a, a clamping block 301b, a pressing ball 301c, a fixing bracket 301d and a first spring 301e. The clamping block 301b is arranged at one end of the moving rod 301a. The number of pressing balls 301c is two, and they are both arranged on one side of the clamping block 301b. The fixing bracket 301d is sleeved outside the pressing ball 301c. The number of the first springs 301e is two, one end of each is fixed to one end of the pressing ball 301c, and the other end is fixed to the inner wall of the fixing bracket 301d.

[0035] The fixing bracket 301d is used to support the first spring 301e.

[0036] When the distance between the two groups of anchor needles 102 needs to be adjusted simultaneously, by moving the moving rod 301a, the movement of the moving rod 301a drives the clamping block 301b to move. When the clamping block 301b moves, one end will squeeze the two pressing balls 301c, and the pressing balls 301c squeeze the first spring 301e. By moving the clamping block 301b until it separates from one end of the pressing ball 301c, at this time, through the elastic force of the first spring 301e rebounding, the pressing ball 301c can be engaged with the clamping block 301b. By the movement of the clamping block 301b, the moving rod 301a can be driven to move, and the moving rod 301a drives the connecting rod 202h to move. By the movement of the connecting rod 202h, the distance between the two groups of anchor needles 102 can be adjusted simultaneously.

[0037] When only one set of anchor needles 102 needs to be adjusted, by moving the extrusion ball 301c, the extrusion ball 301c moves to extrude the first spring 301e. When the extrusion ball 301c moves to separate from the engaging block 301b, the engaging block 301b will return to its original position. The return of the engaging block 301b to its original position drives the moving rod 301a to move, and the moving rod 301a drives the connecting rod 202h to return to its original position. By the movement of the connecting rod 202h, only one set of anchor needles 102 can be adjusted.

[0038] Embodiment 2

[0039] Refer to Figures 1 - 7 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0041] When the distance between two sets of anchor needles 102 needs to be adjusted simultaneously, by moving the hinged rod 202c, the movement of the hinged rod 202c drives the slider 202b to move. When the slider 202b moves to fit with the inner wall of the turntable 201h, by rotating the turntable 201h, the rotation of the inner wall of the turntable 201h drives the slider 202b to rotate, and the slider 202b squeezes the rotating frame 202a to move it. The rotation of the rotating frame 202a can drive two sets of anchor needles 102 to adjust the distance simultaneously.

[0042] Specifically, a collar 202d is hinged on the inner wall of each hinged rod 202c, a rotating rod 202e is inserted into the inner wall of the collar 202d, the other end of the rotating rod 202e is arranged at one end of the rotating frame 202a, and a moving ring 202f is arranged on one side of the collar 202d. The rotating rod 202e is movably connected with the collar 202d.

[0043] Both the moving ring 202f and the collar 202d are movably connected with the rotating rod 202e.

[0044] When the distance between two sets of anchor needles 102 needs to be adjusted simultaneously, by moving the moving ring 202f, the movement of the moving ring 202f drives the collar 202d to move, the movement of the collar 202d drives the hinged rod 202c to move, the movement of the hinged rod 202c drives the slider 202b to move. When the slider 202b moves to fit with the inner wall of the turntable 201h, by rotating the turntable 201h, the rotation of the inner wall of the turntable 201h drives the slider 202b to rotate, and the slider 202b squeezes the rotating frame 202a to move it. The rotation of the rotating frame 202a can drive two sets of anchor needles 102 to adjust the distance simultaneously.

[0045] Specifically, an articulated ring 202g is sleeved outside the moving ring 202f. The articulated ring 202g is movably connected to the moving ring 202f, and a connecting rod 202h is articulated outside the articulated ring 202g.

[0046] By moving the moving rod 301a, the movement of the moving rod 301a drives the movement of the connecting rod 202h. The movement of the connecting rod 202h drives the movement of the articulated ring 202g. The movement of the articulated ring 202g squeezes the moving ring 202f to make it move. Through the movement of the moving ring 202f, the ferrule 202d can be moved.

[0047] Specifically, a second spring 202i is arranged at one end of the moving ring 202f. A positioning block 202j is sleeved outside the rotating rod 202e. One end of the second spring 202i is fixed to one end of the positioning block 202j, and the other end is fixed to one end of the moving ring 202f. A support frame 202k is sleeved outside the rotating rod 202e. A third bevel gear 202l is arranged at one end of the rotating rod 202e. A fourth bevel gear 202m is engaged with one side of the third bevel gear 202l. The other end of the fourth bevel gear 202m is arranged at one end of the connecting rod 201c. A protective frame 202n is sleeved outside the rotating rod 202e.

[0048] The positioning block 202j is used to support the rotating rod 202e. The other end of the positioning block 202j is fixed to the inner wall of the protective frame 202n. The support frame 202k is used to support the rotating rod 202e. The rotating rod 202e is movably connected to the support frame 202k. The other end of the support frame 202k is fixed to the inner wall of the protective frame 202n. By moving the moving rod 301a, the movement of the moving rod 301a drives the movement of the connecting rod 202h. The movement of the connecting rod 202h drives the movement of the articulated ring 202g. The movement of the articulated ring 202g squeezes the moving ring 202f to make it move. The movement of the moving ring 202f will pull the second spring 202i. Through the movement of the moving ring 202f, the ferrule 202d is driven to move, so that the slider 202b fits against the inner wall of the turntable 201h. Then, by rotating the sliding rod 201f, the rotation of the sliding rod 201f drives the rotation of the turntable 201h. The rotation of the sliding rod 201f drives the rotation of the second bevel gear 201e. The rotation of the second bevel gear 201e engages with the first bevel gear 201d to make the first bevel gear 201d rotate. The rotation of the first bevel gear 201d drives the rotation of the connecting rod 201c. The turntable 201h drives the slider 202b to rotate. The slider 202b drives the rotating frame 202a to rotate. The rotating frame 202a drives the rotating rod 202e to rotate. The rotating rod 202e drives the third bevel gear 202l to rotate until it engages with the fourth bevel gear 202m. Through the rotation of the fourth bevel gear 202m, the connecting rod 201c is driven to rotate. Through the rotation of the connecting rod 201c, the threaded rod 201a can be driven to rotate, so that the distance between the two anchor needles 102 can be adjusted simultaneously.

[0049] When only one set of anchor pins 102 needs to be adjusted, by moving the moving rod 301a, at this time, driven by the force of the second spring 202i rebounding, the slider 202b is separated from the turntable 201h, so that one set of anchor pins 102 can be adjusted.

[0050] Specifically, a connecting rod 202h is provided at the bottom of the moving rod 301a. Four slide rails 302a are provided at one end of the fixing frame 301d. Four driving blocks 302b are sleeved outside the slide rails 302a. Two slide plates 302c are provided at one end of the four driving blocks 302b. The other end of the fixing frame 301d is fixed to the top of the protection frame 202n.

[0051] The other end of the protection frame 202n is fixed to one end of the detection frame 101.

[0052] The slide rails 302a are used to support the driving blocks 302b, and the driving blocks 302b are used to support the slide plates 302c. When only one set of anchor pins 102 needs to be adjusted, by moving the slide plates 302c, the movement of the slide plates 302c drives the driving blocks 302b to slide outside the slide rails 302a.

[0053] Embodiment 3

[0054] Referring to Figures 6 - 7 , this is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0055] Specifically, connecting bars 302d are inserted into the inner walls of the slide plates 302c. Two chutes 301d-1 are formed in the inner walls of the fixing frame 301d. The connecting bars 302d are located and slide in the inner walls of the chutes 301d-1, and the other ends are fixed to one ends of the extrusion balls 301c.

[0056] When engaging the extrusion balls 301c, by squeezing the extrusion balls 301c, the movement of the extrusion balls 301c drives the connecting bars 302d to slide in the inner walls of the chutes 301d-1, and the movement of the connecting bars 302d drives the two slide plates 302c to move.

[0057] Specifically, two slide bars 302e are hinged to one end of each of the slide plates 302c. The other ends of the slide bars 302e are hinged to a driving plate 302f. A fixing plate 302g is provided inside the driving plate 302f. The driving plate 302f slides outside the fixing plate 302g, and the other end of the fixing plate 302g is fixed to one end of the fixing frame 301d.

[0058] When only one set of anchor pins 102 needs to be adjusted, by moving the driving plate 302f, the movement of the driving plate 302f will slide outside the fixed plate 302g. The movement of the driving plate 302f drives the slide bar 302e to move, the movement of the slide bar 302e drives the slide plate 302c to move, and the movement of the slide plate 302c drives the connecting bar 302d to slide on the inner wall of the chute 301d-1. The movement of the connecting bar 302d drives the extrusion ball 301c to extrude the first spring 301e. At this time, the limit on the moving rod 301a is released. By the force of the second spring 202i rebounding, the slider 202b can be separated from the turntable 201h, so that only one set of anchor pins 102 can be adjusted.

[0059] When another set of anchor pins 102 needs to be adjusted, by rotating the knob, the rotation of the knob drives the threaded rod 201a to rotate, so that different spacings of the two sets of anchor pins 102 can be adjusted respectively.

[0060] Specifically, a push rod 302h is provided at one end of the driving plate 302f, and a support frame 302i is sleeved outside the driving plate 302f. The other end of the fixed plate 302g is fixed to the inner wall of the support frame 302i.

[0061] The other end of the support frame 302i is fixed to the top of the protection frame 202n.

[0062] A third spring is sleeved outside the push rod 302h. One end of the third spring is fixed to one end of the fixed plate 302g, and the other end is fixed to one end of the driving plate 302f. By extruding the push rod 302h, the movement of the push rod 302h drives the driving plate 302f to move. The driving plate 302f drives the slide bar 302e to move, the slide bar 302e drives the slide plate 302c to move, and the movement of the driving plate 302f will extrude the third spring. The movement of the slide plate 302c drives the connecting bar 302d to slide on the inner wall of the chute 301d-1. The movement of the connecting bar 302d drives the extrusion ball 301c to extrude the first spring 301e. At this time, the limit on the moving rod 301a is released. After the limit is released, by releasing the push rod 302h, at this time, by the force of the third spring rebounding, the driving plate 302f is driven to return to its original position, the driving plate 302f drives the slide plate 302c to return to its original position, the slide plate 302c drives the connecting bar 302d to return to its original position, and the return of the connecting bar 302d drives the extrusion ball 301c to return to its original position for the next use.

[0063] Specifically, it further includes a main body assembly 100, including a detection frame 101, anchor pins 102 and a mechanical sensor 103. The number of anchor pins 102 is four, all of which are arranged at one end of the sliding sleeve 201b. The detection frame 101 is sleeved outside the sliding sleeve 201b, and the mechanical sensor 103 is arranged at one end of the detection frame 101.

[0064] The detection rack 101 is a device for detecting the tensile stress of skin scars, used to judge the degree of scar hyperplasia, contracture tendency, etc., and provide an important basis for formulating personalized treatment plans. The anchor needle 102 is used to detect the tensile stress of skin scars, and the mechanical sensor 103 can sense various mechanical actions received by the skin scar in real time, including tensile force, pressure, and shear force.

[0065] When in use, when it is necessary to adjust the spacing of the two groups of anchor needles 102 at the same time, by moving the moving rod 301a, the movement of the moving rod 301a drives the engagement block 301b to move. When the engagement block 301b moves, one end will squeeze the two extrusion balls 301c, and the extrusion ball 301c squeezes the first spring 301e. By moving the engagement block 301b to separate from one end of the extrusion ball 301c, at this time, through the elastic force of the first spring 301e rebounding, the extrusion ball 301c can be engaged with the engagement block 301b. By moving the engagement block 301b, the moving rod 301a can be driven to move. The moving rod 301a drives the connecting rod 202h to move, and the connecting rod 202h drives the hinge ring 202g to move. The movement of the hinge ring 202g squeezes the moving ring 202f to make it move. The movement of the moving ring 202f will pull the second spring 202i. The movement of the moving ring 202f drives the ferrule 202d to move. The movement of the ferrule 202d drives the hinge rod 202c to move. The movement of the hinge rod 202c drives the slider 202b to move. When the slider 202b moves to fit the inner wall of the turntable 201h, the spacing of the two groups of anchor needles 102 can be adjusted at the same time. Then, by rotating the sliding rod 201f, the rotation of the sliding rod 201f squeezes the fixed groove 201g-1 to make the fixed sleeve 201g rotate. The rotation of the fixed sleeve 201g drives the turntable 201h to rotate. The rotation of the sliding rod 201f drives the second bevel gear 201e to rotate. The rotation of the second bevel gear 201e meshes with the first bevel gear 201d to make the first bevel gear 201d rotate. The rotation of the first bevel gear 201d drives the connecting rod 201c to rotate. The connecting rod 201c drives the threaded rod 201a to rotate. The rotation of the threaded rod 201a can drive the guide groove to squeeze the guide block, making the guide block move. The guide block can drive the sliding sleeve 201b to move through the movement, so that the two sliding sleeves 201b move towards each other. The rotation of the turntable 201h drives the slider 202b to rotate. The slider 202b squeezes the rotating frame 202a to make it move. The rotation of the rotating frame 202a drives the rotating rod 202e to rotate. The rotating rod 202e drives the third bevel gear 202l to rotate until it meshes with the fourth bevel gear 202m. Through the rotation of the fourth bevel gear 202m, the connecting rod 201c is driven to rotate. Through the rotation of the connecting rod 201c, the threaded rod 201a can be driven to rotate, so that the spacing of the two groups of anchor needles 102 can be adjusted at the same time.

[0066] When only one set of anchor pins 102 needs to be adjusted, by squeezing the push rod 302h, the movement of the push rod 302h drives the movement of the driving plate 302f, the driving plate 302f drives the movement of the slide bar 302e, the slide bar 302e drives the movement of the slide plate 302c, and the movement of the driving plate 302f will squeeze the third spring. The movement of the slide plate 302c drives the connecting bar 302d to slide on the inner wall of the chute 301d-1. The movement of the connecting bar 302d drives the extrusion ball 301c to squeeze the first spring 301e, so that the extrusion ball 301c is separated from the engaging block 301b. At this time, the limit on the moving rod 301a is released. At this time, by the force of the second spring 202i rebounding, the slider 202b can be separated from the turntable 201h, so that one set of anchor pins 102 can be adjusted. After the limit is released, by releasing the push rod 302h, at this time, by the force of the third spring rebounding, the driving plate 302f is driven back to its original position, the driving plate 302f drives the slide plate 302c back to its original position, the slide plate 302c drives the connecting bar 302d back to its original position, and the connecting bar 302d drives the extrusion ball 301c back to its original position when it returns to its original position.

[0067] When another set of anchor pins 102 needs to be adjusted, by rotating the knob, the rotation of the knob drives the rotation of the threaded rod 201a, so that different spacings of the two sets of anchor pins 102 can be adjusted respectively.
