Description

Technical Field

[0001] The present invention relates to the technical field of surgical traction equipment, in particular to a common surgical traction device and a use method thereof. Background Art

[0002] During critical care treatment, patients often need to undergo incision surgery, so a retractor is needed to pull open the skin and flesh on both sides of the opening of the patient's lesion to expose a larger space for the doctor to perform surgery. In the actual operation, due to the elasticity of the skin, the retractor will loosen after the skin and flesh relax, affecting the doctor's subsequent operations, so a traction device is needed to adjust the retractor.

[0003] Among them, when performing traction on the wound of the limbs, the wound needs to be opened horizontally to facilitate the exposure of the inside of the wound to the outside, and finally the surgeon performs the surgical operation. The wound that is opened outward may cause the edge of the wound to crack, and the cracked skin will cause the wound to loosen, affecting the surgeon's operating accuracy. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a general surgical traction device, comprising a telescopic base, six tooth columns are rotatably connected to both sides of the telescopic base, a clamping track 1 is fixedly connected to the outer walls of the four tooth columns, an arc-shaped slider 1 is slidably connected to the inner wall of the clamping track 1, a hydraulic telescopic tube 1 is fixedly connected to the bottom of the arc-shaped slider 1, an extrusion frame is fixedly connected to the top of the arc-shaped slider 1, and a transmission hose is connected through the side wall of the hydraulic telescopic tube 1; The hydraulic mechanism includes a clamping track 2 fixedly connected to the outer walls of the two tooth columns, a hydraulic telescopic tube 2 fixedly connected to the inner wall of the clamping track 2, an arc-shaped rod 1 fixedly connected to the side wall of the hydraulic telescopic tube 2, an arc-shaped slider 2 slidably connected to the inner wall of the clamping track 2, a handle fixedly connected to the side wall of the arc-shaped slider 2, a linkage component fixedly connected to the inner wall of the arc-shaped slider 2, and a locking component fixedly connected to the inner wall of the arc-shaped slider 2; The limiting mechanism includes six L-shaped frames fixedly connected to the bottom of the telescopic base, an L-shaped sliding plate is slidably connected to the inner wall of the through hole of the L-shaped frame, an inclined surface is provided on the side wall of the L-shaped sliding plate, and a pulling spring is fixedly connected to the side wall of the L-shaped sliding plate. Before use, the patient's limbs are placed on the telescopic base, and the medical staff squeezes the clamping track 2 and the clamping track 1 inward, forcing the side wall of the arc-shaped slider 2 to contact the skin of the limb, and the medical staff then drives the arc-shaped slider 2 to slide downward along the inner wall of the clamping track 2 through the handle. At this time, the arc-shaped slider 2 will drive the skin of the side wall to slide downward synchronously, so that the wound opens to both ends, and the downward movement of the arc-shaped slider 2 will drive the arc-shaped rod 1 to squeeze the hydraulic telescopic tube 2, so that the liquid inside the hydraulic telescopic tube 2 is transmitted to the inside of the hydraulic telescopic tube 1 through the gear column, forcing the hydraulic telescopic tube 1 to drive the arc-shaped slider 1 and the squeezing frame to slide upward, forcing the squeezing frames at both ends to approach each other, and clamping and limiting the two ends of the wound. When the arc-shaped slider 2 moves down to the lowest point, the medical staff locks it through the locking component to prevent the component from being reset. Through the application of the above components, the wound is prevented from having skin cracking due to the traction force during the traction process.

[0005] Preferably, the linkage assembly includes a slide plate fixedly connected to the inner wall of the arc-shaped slider 2, a pneumatic slide plate slidably connected to the side wall of the slide plate, an arc-shaped rod 2 fixedly connected to the bottom of the arc-shaped slider 2, an arc-shaped rod 3 fixedly connected to the bottom of the pneumatic slide plate, a piston plate slidably connected to the outer wall of the arc-shaped rod 2, and an arc-shaped hydraulic box fixedly connected to the inner wall of the clamping track 2. The design of clamping the wound port by the extrusion frame and opening the wound by the arc-shaped slider 2 reduces traction on the skin around the wound during use of the device, avoids deformation of the wound skin due to long-term deformation of the wound, and causes uneven wounds due to deformation of the skin when subsequent medical staff sew the skin. In addition, the device is mostly used in surgical operations on the limbs, and the movement of the limbs will restore the activity of the wound, resulting in loose threads when the skin recovers.

[0006] Preferably, the linkage assembly also includes a return spring fixedly connected to the side wall of the piston plate, one end of the return spring away from the piston plate is slidably connected to the inner wall of the arc hydraulic box, one end of the arc rod three away from the arc slider two is fixedly connected to the outer wall of the piston plate, and a ramp rod is fixedly connected to the inner wall of the arc hydraulic box.

[0007] Preferably, the linkage assembly also includes a push rod slidably connected to the inner wall of the arc-shaped slider 2, a control assembly is fixedly connected to the side wall of the piston plate, a reset assembly is fixedly connected to the inner wall of the piston plate, the outer wall of the arc-shaped rod 3 is slidably connected to the inner wall of the arc-shaped hydraulic box through hole, and the outer wall of the arc-shaped rod 2 is slidably connected to the inner wall of the arc-shaped hydraulic box through hole. In view of the phenomenon that the thickness of the limbs is uneven, a limiting mechanism is provided inside the equipment. When the medical staff squeezes the clamping track 1 and the clamping track 2 inward, the L-shaped sliding plate will be pulled by the pulling spring so that one end of the L-shaped sliding plate will contact the outer wall of the tooth column, and when the tooth column rotates, the outer wall of the tooth column will contact the inclined surface of the L-shaped sliding plate, and force the L-shaped sliding plate to move downward along the inner wall of the L-shaped frame, presenting a Figure 5 The state shown in the figure, after the clamping track 1 completes the swing, the elasticity of the skin and muscles will force the clamping track 1 and the tooth column to reset and rotate, and at this time the outer wall of the tooth column will contact the vertical surface of the L-shaped sliding plate, and the vertical surface of the L-shaped sliding plate will limit the reset of the tooth column. Through the application of the above components, the stable pressure of the clamping track 1 and the clamping track 2 is guaranteed to avoid the relaxation of the clamping track 2 and the clamping track 1, which will cause the failure of wound opening.

[0008] Preferably, the control assembly includes a flow hole opened on the outer wall of the piston plate, the top of the piston plate is rotatably connected to a rotating plate, the top of the piston plate is fixedly connected to an L-shaped fixed plate, and the bottom of the L-shaped fixed plate is fixedly connected to a push spring.

[0009] Preferably, the reset assembly includes an installation groove 1 opened at the bottom of the piston plate, an installation groove 2 is opened on the inner wall of the installation groove 1, an inclined slider is slidably connected to the inner wall of the installation groove 2, a push spring 2 is fixedly connected to the side wall of the inclined slider, and a limiting block is opened on the side wall of the arc rod 2.

[0010] Preferably, the reset assembly also includes a roller fixedly connected to the bottom of the inclined slider, one end of the arc rod 1 away from the hydraulic telescopic tube 2 is fixedly connected to the bottom of the arc slider 2, and one end of the hydraulic telescopic tube 1 away from the arc slider 1 is fixedly connected to the inner wall of the clamping track 1. Utilizing the characteristic of the downward movement of the above arc slider 2, a linkage assembly and a control assembly are arranged inside the device. When the arc slider 2 moves downward, the piston plate is driven by the arc rod 2 to slide downward along the inner wall of the arc rod 3, forcing the solution at the bottom of the piston plate to enter the top of the piston plate through the flow hole, and the piston plate squeezes the reset spring to accumulate mechanical power in the reset spring. When the arc rod 2 reaches the bottom, the inclined surface of the inclined rod will contact the outer surface of the roller, and the inclined inclined rod will force the inclined slider to slide outward along the inner wall of the mounting groove 2 through the roller, so that the inclined slider is away from the limiting block, and the inclined slider contacts the restriction on the arc rod 2. At this time, the reset spring will release the mechanical power, forcing the piston plate to slide upward along the outer wall of the limiting block and the inner wall of the arc hydraulic box. In this process, the push spring will push the rotating plate to cover the top of the flow hole, presenting a Figure 8In the state shown, the rotating plate cannot completely cover the flow hole, so that a small flow opening is formed between the flow hole and the rotating plate, and the liquid on the top of the piston plate returns to the bottom of the piston plate through the above small flow opening. During the return process of the liquid, the liquid is restricted by the small flow opening, resulting in the piston plate moving up along the arc hydraulic box. The speed is slowed down, and the piston plate drives the air pressure slide plate to move upward along the inner wall of the slide plate through the arc rod three, and the upward movement of the air pressure slide plate will squeeze the air inside the arc slider two, forcing the ejection rod to move outward. Through the application of the above components, after the arc slider two completes the skin support, the ejection rod slowly moves outward. The outward movement of the ejection rod will increase the friction between the ejection rod and the outer wall of the skin, thereby avoiding slight deformation of the skin at the compressed position after the skin is under pressure for a long time, resulting in a decrease in the friction between the skin on the side of the wound and the friction plate during the operation, causing the wound to be relocated.

[0011] A method for using a general surgical traction device comprises the following steps: S1: Before use, the patient's limb is placed on the telescopic base, and the medical staff squeezes the clamping track 2 and the clamping track 1 inward to force the side wall of the arc-shaped slider 2 to contact the skin of the limb; S2: The medical staff then drives the arc-shaped slider 2 to slide downward along the inner wall of the clamping track 2 through the handle. At this time, the arc-shaped slider 2 drives the skin of the side wall to slide downward synchronously, so that the wound opens to both ends; S3: The downward movement of the arc-shaped slider 2 will drive the arc-shaped rod 1 to squeeze the hydraulic telescopic tube 2, so that the liquid inside the hydraulic telescopic tube 2 is transmitted to the inside of the hydraulic telescopic tube 1 through the gear column, forcing the hydraulic telescopic tube 1 to drive the arc-shaped slider 1 and the extrusion frame to slide upward, forcing the extrusion frames at both ends to approach each other, and clamping and restricting the two ends of the wound.

[0012] The present invention has the following beneficial effects: (1) In view of the influence of the traction on the wound opening toward both ends, the present invention is provided with a hydraulic mechanism and a limiting mechanism inside the device. Before use, the patient's limb is placed on the telescopic base, and the medical staff squeezes the clamping track 2 and the clamping track 1 inwardly, forcing the side wall of the arc-shaped slider 2 to contact the skin of the limb. The medical staff then drives the arc-shaped slider 2 to slide downward along the inner wall of the clamping track 2 through the handle. At this time, the arc-shaped slider 2 will drive the skin of the side wall to slide downward synchronously, so that the wound opens toward both ends. The downward movement of the arc-shaped slider 2 will drive the arc-shaped rod 1 to squeeze the hydraulic telescopic tube 2, so that the liquid inside the hydraulic telescopic tube 2 is transmitted to the inside of the hydraulic telescopic tube 1 through the gear column, forcing the hydraulic telescopic tube 1 to drive the arc-shaped slider 1 and the extrusion frame to slide upward, forcing the extrusion frames at both ends to approach each other, and clamping and limiting the two ends of the wound. When the arc-shaped slider 2 moves down to the lowest point, the medical staff locks it through the locking component to prevent the component from resetting. Through the application of the above-mentioned component, the wound will not be ruptured due to the traction force during the traction process.

[0013] (2) The present invention utilizes the design of clamping the wound port through the extrusion frame and opening the wound with two arc-shaped sliders, so that during the use of the device, the traction on the skin around the wound is reduced, and the deformation of the wound skin due to long-term deformation of the wound is avoided, resulting in uneven wounds when the medical staff suture the skin later. In addition, the device is mostly used in surgical operations on the limbs. The movement of the limbs will restore the activity of the wound, resulting in the phenomenon of loose thread ends when the skin recovers.

[0014] (3) The present invention utilizes the characteristic of the arc-shaped slider 2 moving downward, and a linkage component and a control component are arranged inside the device. When the arc-shaped slider 2 moves downward, the arc-shaped rod 2 drives the piston plate to slide downward along the inner wall of the arc-shaped rod 3, forcing the solution at the bottom of the piston plate to enter the top of the piston plate through the flow hole, and the piston plate squeezes the reset spring, so that the reset spring accumulates mechanical power. When the arc-shaped rod 2 reaches the bottom, the inclined surface of the inclined rod will contact the outer surface of the roller, and the inclined inclined rod will force the inclined slider to slide outward along the inner wall of the installation groove 2 through the roller, so that the inclined slider moves away from the limiting block. The inclined slider contacts the restriction on the arc-shaped rod 2, and at this time the reset spring will release the mechanical power, forcing the piston plate to slide upward along the outer wall of the limiting block and the inner wall of the arc-shaped hydraulic box. In this process, the push spring will push the rotating plate to cover the top of the flow hole, presenting a Figure 8 In the state shown, the rotating plate cannot completely cover the flow hole, so that a small flow opening is formed between the flow hole and the rotating plate, and the liquid on the top of the piston plate returns to the bottom of the piston plate through the above small flow opening. During the return process of the liquid, the liquid is restricted by the small flow opening, resulting in the piston plate moving up along the arc hydraulic box. The speed is slowed down, and the piston plate drives the air pressure slide plate to move upward along the inner wall of the slide plate through the arc rod three, and the upward movement of the air pressure slide plate will squeeze the air inside the arc slider two, forcing the ejection rod to move outward. Through the application of the above components, after the arc slider two completes the skin support, the ejection rod slowly moves outward. The outward movement of the ejection rod will increase the friction between the ejection rod and the outer wall of the skin, thereby avoiding slight deformation of the skin at the compressed position after the skin is under pressure for a long time, resulting in a decrease in the friction between the skin on the side of the wound and the friction plate during the operation, causing the wound to be relocated.

[0015] (4) In view of the problem that the thickness of the upper and lower limbs is not the same, a limiting mechanism is arranged inside the device. When the medical staff squeezes the clamping track 1 and the clamping track 2 inward, the L-shaped sliding plate will be pulled by the pulling spring so that one end of the L-shaped sliding plate will contact the outer wall of the tooth column. When the tooth column rotates, the outer wall of the tooth column will contact the inclined surface of the L-shaped sliding plate, and force the L-shaped sliding plate to move downward along the inner wall of the L-shaped frame, presenting a Figure 5The state shown in the figure, after the clamping track 1 completes the swing, the elasticity of the skin and muscles will force the clamping track 1 and the tooth column to reset and rotate, and at this time the outer wall of the tooth column will contact the vertical surface of the L-shaped sliding plate, and the vertical surface of the L-shaped sliding plate will limit the reset of the tooth column. Through the application of the above components, the stable pressure of the clamping track 1 and the clamping track 2 is guaranteed to avoid the relaxation of the clamping track 2 and the clamping track 1, which will cause the failure of wound opening.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] For example, see Figure 1 - Figure 5 The present invention is a general surgical traction device, comprising a telescopic base 1, six tooth columns 11 are rotatably connected to both sides of the telescopic base 1, a clamping track 12 is fixedly connected to the outer wall of the four tooth columns 11, an arc-shaped slider 13 is slidably connected to the inner wall of the clamping track 12, a hydraulic telescopic tube 14 is fixedly connected to the bottom of the arc-shaped slider 13, an extrusion frame 16 is fixedly connected to the top of the arc-shaped slider 13, and a transmission hose 15 is connected through the side wall of the hydraulic telescopic tube 14; The hydraulic mechanism 2 includes a clamping track 21 fixedly connected to the outer walls of the two tooth columns 11, a hydraulic telescopic tube 22 fixedly connected to the inner wall of the clamping track 21, an arc-shaped rod 23 fixedly connected to the side wall of the hydraulic telescopic tube 22, an arc-shaped slider 24 slidably connected to the inner wall of the clamping track 21, a handle 25 fixedly connected to the side wall of the arc-shaped slider 24, a linkage component 4 fixedly connected to the inner wall of the arc-shaped slider 24, and a locking component 17 fixedly connected to the inner wall of the arc-shaped slider 24; The limiting mechanism 3 includes six L-shaped frames 31 fixedly connected to the bottom of the telescopic base 1, and an L-shaped sliding plate 32 is slidably connected to the inner wall of the through hole of the L-shaped frame 31. The side wall of the L-shaped sliding plate 32 is provided with an inclined surface, and the side wall of the L-shaped sliding plate 32 is fixedly connected with a pulling spring 33. Before use, the patient's limb is placed on the telescopic base 1, and the medical staff squeezes the clamping track 21 and the clamping track 1 12 inward to force the side wall of the arc-shaped slider 24 to contact the skin of the limb, and the medical staff then drives the handle 25 The arc-shaped slider 24 slides downward along the inner wall of the clamping track 21. At this time, the arc-shaped slider 24 will drive the skin of the side wall to slide downward synchronously, so that the wound opens to both ends. The downward movement of the arc-shaped slider 24 will drive the arc-shaped rod 1 23 to squeeze the hydraulic telescopic tube 22, so that the liquid inside the hydraulic telescopic tube 22 is transmitted to the inside of the hydraulic telescopic tube 14 through the tooth column 11, forcing the hydraulic telescopic tube 14 to drive the arc-shaped slider 13 and the extrusion frame 16 to slide upward, forcing the extrusion frames 16 at both ends to approach each other, and clamping and restricting the two ends of the wound. When the arc-shaped slider 24 moves down to the lowest point, the medical staff locks it through the locking component 17 to prevent the component from being reset. Through the application of the above-mentioned components, the wound will not be ruptured due to the traction force during the traction process.

[0021] For example 2, please refer to Figure 6 - Fig.11 The present invention is a general surgical traction device. On the basis of the first embodiment, the linkage assembly 4 includes a slide plate 41 fixedly connected to the inner wall of the arc-shaped slider 24, a pneumatic slide plate 42 is slidably connected to the side wall of the slide plate 41, an arc-shaped rod 2 43 is fixedly connected to the bottom of the arc-shaped slider 24, an arc-shaped rod 3 44 is fixedly connected to the bottom of the pneumatic slide plate 42, a piston plate 45 is slidably connected to the outer wall of the arc-shaped rod 2 43, and an arc-shaped hydraulic box 49 is fixedly connected to the inner wall of the clamping track 21. By clamping the wound port through the extrusion frame 16 and opening the wound with the arc-shaped slider 24, the device reduces the traction on the skin around the wound during use, avoids the deformation of the wound skin due to long-term deformation of the wound, and causes the deformation of the skin to cause the wound to be uneven when the medical staff sews the skin later; in addition, the device is mostly used in surgical operations on the limbs, and the movement of the limbs will restore the activity of the wound, resulting in the phenomenon of loose thread ends when the skin recovers.

[0022] The linkage assembly 4 also includes a return spring 46 fixedly connected to the side wall of the piston plate 45, and one end of the return spring 46 away from the piston plate 45 is slidably connected to the inner wall of the arc hydraulic box 49, and one end of the arc rod three 44 away from the arc slider two 24 is fixedly connected to the outer wall of the piston plate 45, and a ramp rod 47 is fixedly connected to the inner wall of the arc hydraulic box 49.

[0023] The linkage assembly 4 also includes a push rod 48 slidably connected to the inner wall of the arc-shaped slider 24, a control assembly 5 is fixedly connected to the side wall of the piston plate 45, and a reset assembly 6 is fixedly connected to the inner wall of the piston plate 45. The outer wall of the arc-shaped rod 3 44 is slidably connected to the inner wall of the through hole of the arc-shaped hydraulic box 49, and the outer wall of the arc-shaped rod 2 43 is slidably connected to the inner wall of the through hole of the arc-shaped hydraulic box 49. In view of the phenomenon that the thickness of the limbs is uneven, a limiting mechanism 3 is provided inside the equipment. When the medical staff squeezes the clamping rail 12 and the clamping rail 21 inward, the L-shaped sliding plate 32 will be pulled by the pulling spring 33, so that one end of the L-shaped sliding plate 32 will contact the outer wall of the tooth column 11, and when the tooth column 11 rotates, the outer wall of the tooth column 11 will contact the inclined surface of the L-shaped sliding plate 32, and force the L-shaped sliding plate 32 to move downward along the inner wall of the L-shaped frame 31, presenting a Figure 5 The state shown in the figure, after the clamping track 12 completes the swing, the elasticity of the skin and muscles will force the clamping track 12 and the tooth column 11 to reset and rotate, and at this time the outer wall of the tooth column 11 will contact the vertical surface of the L-shaped sliding plate 32, and the vertical surface of the L-shaped sliding plate 32 will limit the reset of the tooth column 11. Through the application of the above-mentioned components, the stable pressure of the clamping track 12 and the clamping track 21 is guaranteed to prevent the clamping track 21 and the clamping track 12 from loosening, resulting in failure of wound opening.

[0024] The control assembly 5 includes a flow hole 51 opened on the outer wall of the piston plate 45, the top of the piston plate 45 is rotatably connected to a rotating plate 52, the top of the piston plate 45 is fixedly connected to an L-shaped fixed plate 53, and the bottom of the L-shaped fixed plate 53 is fixedly connected to a push spring 54.

[0025] The reset assembly 6 includes a mounting groove 61 provided at the bottom of the piston plate 45, a mounting groove 62 provided at the inner wall of the mounting groove 61, a sloped slider 63 slidably connected to the inner wall of the mounting groove 62, a push spring 64 fixedly connected to the side wall of the sloped slider 63, and a limiting block 65 provided at the side wall of the arc rod 43.

[0026] The reset assembly 6 also includes a roller 66 fixedly connected to the bottom of the inclined slider 63, and the end of the arc rod 1 23 away from the hydraulic telescopic tube 22 is fixedly connected to the bottom of the arc slider 24, and the end of the hydraulic telescopic tube 14 away from the arc slider 13 is fixedly connected to the inner wall of the clamping track 12. Taking advantage of the downward movement of the above arc slider 24, a linkage assembly 4 and a control assembly 5 are arranged inside the device. When the arc slider 24 moves downward, the piston plate 45 is driven to slide downward along the inner wall of the arc rod 3 44 through the arc rod 2 43, forcing the solution at the bottom of the piston plate 45 to enter the top of the piston plate 45 through the flow hole 51, and the piston plate 45 The return spring 46 is squeezed to accumulate mechanical power. When the arc rod 43 reaches the bottom, the inclined surface of the inclined rod 47 will contact the outer surface of the roller 66. The inclined inclined rod 47 will force the inclined slider 63 to slide outward along the inner wall of the installation groove 62 through the roller 66, so that the inclined slider 63 is away from the limiting block 65. The inclined slider 63 contacts the restriction on the arc rod 43. At this time, the return spring 46 will release the mechanical power, forcing the piston plate 45 to slide upward along the outer wall of the limiting block 65 and the inner wall of the arc hydraulic box 49. In this process, the push spring 54 will push the rotating plate 52 to cover the top of the flow hole 51, presenting a Figure 8 In the state shown, the rotating plate 52 cannot completely cover the flow hole 51, so that a small flow opening is formed between the flow hole 51 and the rotating plate 52, and the liquid on the top of the piston plate 45 returns to the bottom of the piston plate 45 through the above small flow opening. During the return process of the liquid, the liquid is restricted by the small flow opening, resulting in the piston plate 45 moving up along the arc hydraulic box 49. The speed slows down, and the piston plate 45 drives the air pressure slide 42 to move upward along the inner wall of the slide 41 through the arc rod three 44, and the upward movement of the air pressure slide 42 will squeeze the air inside the arc slider two 24, forcing the ejection rod 48 to move outward. Through the application of the above-mentioned components, after the arc slider two 24 completes the skin support, the ejection rod 48 slowly moves outward. The outward movement of the ejection rod 48 will increase the friction between the ejection rod 48 and the outer wall of the skin, thereby avoiding slight deformation of the skin at the compressed position after the skin is compressed for a long time, resulting in a decrease in the friction between the skin on the side of the wound and the friction plate during the operation, causing the wound to be relocated.

[0027] The traction method of the traction device comprises the following steps: S1: Before use, the patient's limb is placed on the telescopic base 1, and the medical staff squeezes the clamping track 2 21 and the clamping track 1 12 inward to force the side wall of the arc-shaped slider 2 24 to contact the skin of the limb; S2: The medical staff then drives the second arc-shaped slider 24 to slide downward along the inner wall of the second clamping track 21 through the handle 25. At this time, the second arc-shaped slider 24 drives the skin of the side wall to slide downward synchronously, so that the wound opens to both ends; S3: The arc-shaped slider 24 moves downward to drive the arc-shaped rod 1 23 to squeeze the hydraulic telescopic tube 2 22, so that the liquid inside the hydraulic telescopic tube 22 is transmitted to the inside of the hydraulic telescopic tube 14 through the tooth column 11, forcing the hydraulic telescopic tube 14 to drive the arc-shaped slider 13 and the extrusion frame 16 to slide upward, forcing the extrusion frames 16 at both ends to approach each other and clamp and restrict the two ends of the wound.

[0028] A specific application of this embodiment is as follows: before use, the patient's limb is placed on the telescopic base 1, and the medical staff squeezes the clamping track 21 and the clamping track 1 12 inward, forcing the side wall of the arc-shaped slider 24 to contact the skin of the limb, and then the medical staff drives the arc-shaped slider 24 to slide downward along the inner wall of the clamping track 21 through the handle 25. At this time, the arc-shaped slider 24 will drive the skin of the side wall to slide downward synchronously, so that the wound opens to both ends, and the downward movement of the arc-shaped slider 24 will drive the arc-shaped rod 1 23 to squeeze the hydraulic telescopic tube 2 22, so that the liquid inside the hydraulic telescopic tube 22 is transmitted to the inside of the hydraulic telescopic tube 1 14 through the tooth column 11, forcing the hydraulic telescopic tube 1 14 to drive the arc-shaped slider 1 13 and the extrusion frame 16 to slide upward, forcing the extrusion frames 16 at both ends to approach each other, and clamping and restricting the two ends of the wound. When the arc-shaped slider 24 moves down to the lowest point, the medical staff locks it through the locking component 17 to prevent the component from being reset. Through the application of the above-mentioned components, the wound will not be cracked due to the traction force during the traction process. The design of clamping the wound port through the above-mentioned extrusion frame 16 and opening the wound with the arc-shaped slider 24 reduces the traction on the skin around the wound during the use of the device, and avoids the deformation of the wound skin due to long-term deformation of the wound, which causes the deformation of the skin to cause uneven wounds when the medical staff sews the skin later. In addition, the device is mostly used in surgical operations on the limbs. The movement of the limbs will restore the activity of the wound, resulting in loose threads when the skin recovers.

[0029] Taking advantage of the downward movement of the arc-shaped slider 24, a linkage assembly 4 and a control assembly 5 are provided inside the device. When the arc-shaped slider 24 moves downward, the arc-shaped rod 2 43 drives the piston plate 45 to slide downward along the inner wall of the arc-shaped rod 3 44, forcing the solution at the bottom of the piston plate 45 to enter the top of the piston plate 45 through the flow hole 51, and the piston plate 45 squeezes the reset spring 46, so that the reset spring 46 accumulates mechanical power. When the arc-shaped rod 2 43 reaches the bottom, the inclined surface of the inclined surface rod 47 will contact with the roller 66, the inclined bevel rod 47 will force the bevel slider 63 to slide outward along the inner wall of the second installation groove 62 through the roller 66, so that the bevel slider 63 is away from the limiting block 65, and the bevel slider 63 contacts the restriction of the arc rod 43. At this time, the return spring 46 will release the mechanical power, forcing the piston plate 45 to slide upward along the outer wall of the limiting block 65 and the inner wall of the arc hydraulic box 49. In this process, the push spring 54 will push the rotating plate 52 to cover the top of the flow hole 51, presenting as shown in the figure. Figure 8 In the state shown, the rotating plate 52 cannot completely cover the flow hole 51, so that a small flow opening is formed between the flow hole 51 and the rotating plate 52, and the liquid on the top of the piston plate 45 returns to the bottom of the piston plate 45 through the above small flow opening. During the return process of the liquid, the liquid is restricted by the small flow opening, resulting in the piston plate 45 moving up along the arc hydraulic box 49. The speed slows down, and the piston plate 45 drives the air pressure slide 42 to move upward along the inner wall of the slide 41 through the arc rod three 44, and the upward movement of the air pressure slide 42 will squeeze the air inside the arc slider two 24, forcing the ejection rod 48 to move outward. Through the application of the above-mentioned components, after the arc slider two 24 completes the skin support, the ejection rod 48 slowly moves outward. The outward movement of the ejection rod 48 will increase the friction between the ejection rod 48 and the outer wall of the skin, thereby avoiding slight deformation of the skin at the compressed position after the skin is compressed for a long time, resulting in a decrease in the friction between the skin on the side of the wound and the friction plate during the operation, causing the wound to be relocated.

[0030] In view of the phenomenon that the thickness of the limbs is not the same, a limiting mechanism 3 is provided inside the device. When the medical staff squeezes the clamping track 12 and the clamping track 21 inward, the L-shaped sliding plate 32 will be pulled by the pulling spring 33 so that one end of the L-shaped sliding plate 32 contacts the outer wall of the tooth column 11, and when the tooth column 11 rotates, the outer wall of the tooth column 11 contacts the inclined surface of the L-shaped sliding plate 32, and forces the L-shaped sliding plate 32 to move downward along the inner wall of the L-shaped frame 31, presenting a Figure 5The state shown in the figure, after the clamping track 12 completes the swing, the elasticity of the skin and muscles will force the clamping track 12 and the tooth column 11 to reset and rotate, and at this time the outer wall of the tooth column 11 will contact the vertical surface of the L-shaped sliding plate 32, and the vertical surface of the L-shaped sliding plate 32 will limit the reset of the tooth column 11. Through the application of the above-mentioned components, the stable pressure of the clamping track 12 and the clamping track 21 is guaranteed to prevent the clamping track 21 and the clamping track 12 from loosening, resulting in failure of wound opening.
