Description

Technical Field

[0001] The invention relates to the technical field of skin pulling, and in particular to a skin pulling device for surgical operation. Background Art

[0002] There are many types of surgical operations, covering general surgery, cardiothoracic surgery, neurosurgery, hepatobiliary surgery, urological surgery, orthopedic surgery, decompression and debridement, etc. Among them, decompression and debridement is a procedure for controlling the progression of infectious lesions or pressure injuries by removing necrotic tissue, clearing pus and relieving pressure, such as abscess incision and drainage, bedsore debridement, etc.

[0003] During decompression and debridement surgery, it is necessary to use a scalpel to cut the skin of the surgical area in the surgical area, thereby making a surgical incision. The doctor then holds the surgical instrument to perform debridement on the area. After the operation, the skin at the opened incision needs to be brought closer to facilitate faster healing of the wound in the incision area. In the prior art, there is a "zipper-type skin traction device" that uses a high-strength hydrocolloid adhesive to stick the device on both sides of the incision, and then gently pulls the buckle zipper part on the device to pull and tighten the skin of the incision part, thereby tightening the skin on both sides of the incision. On this basis, it is easy to think of making the buckle zipper part of a rigid material, which can be achieved during the incision. After the incision is made, the adhesive parts on both sides are moved away from each other, so that the skin on both sides of the incision are moved away from each other, thereby achieving the effect of pulling the skin at the incision away and ensuring that the incision is in an open state. In this way, the area that needs to be debridement can be fully exposed, so that the doctor can clearly see the depth, range and nature of the wound, which is convenient for the doctor to perform debridement surgery. However, when the adhesive parts of the zipper-type skin traction device are moved away from each other, since the skin is only pulled in both directions, the incision cannot be in a more rounded state, thereby affecting the doctor's observation of the depth, range and nature of the wound, thereby affecting the effect of pulling the skin to open the incision.

[0031] 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.

[0032] See also Figures 1 to 5The present invention provides a technical solution: a skin traction device for surgical operation, comprising an elastic plate 1, and two elastic plates 1 are provided, the elastic plates 1 themselves have elastic force, small blocks 3 are fixedly connected to the front and rear ends of the two elastic plates 1, a slide seat 2 is commonly provided at the end of the two small blocks 3 at the same end away from the elastic plate 1, a movable plate 4 is fixedly connected to the end of the slide seat 2 away from the elastic plate 1, an adhesive component 5 is provided at the bottom of the elastic plate 1, and a movable limiting component 6 is provided on the left and right sides between the two movable plates 4, the movable limiting component 6 comprises a fixed tube 61 fixedly connected to the left and right sides of the end close to the two movable plates 4, the rear end of the fixed tube 61 at the front end is fixedly connected to the through tube 62, the front end of the fixed tube 61 at the rear end is fixedly connected to the sleeve 63, and the rear end of the outer wall of the through tube 62 is slidably connected to the front end of the sleeve 63.

[0033] By adopting the above technical solution, before the debridement and excision surgery, under the elastic force of the elastic plate 1 itself, the elastic plate 1 is in a relatively straight state, and is slightly bent inward, and the device is placed at the position where the patient needs to debride the opening, and then the skin of the patient's debridement area is adhered by the adhesive component 5 set at the bottom of the two elastic plates 1. The doctor can use a scalpel to make a surgical opening at the position between the two elastic plates 1. After the opening, the movable plates 4 at the front and rear ends are manually pressed to make the two movable plates 4 move in a direction close to each other, so that the slide seat 2 and the small block 3 at the front and rear ends move, so that the elastic plate 1 can be made to move. It is in a bent state, so that the adhesive component 5 pulls the skin, thereby stretching the skin of the incision part, which is convenient for the doctor to perform debridement surgery. When the skin is pulled to stretch the incision, since the elastic plate 1 is in a bent state, the cutting edge is in a relatively round state, which is convenient for the doctor to clearly see the depth, range and nature of the wound, and is convenient for the doctor to perform debridement surgery and better perform debridement and excision surgery. This improves the effect of pulling the skin to stretch the incision. When stretched, the two movable plates 4 can be limited by the limiting component 6, so that the elastic plate 1 is in a relatively bent state.

[0034] It should be noted that when the operation is completed, the limiting effect of the two movable plates 4 is cancelled by the limiting component 6, and the elastic plate 1 can return to its initial slightly bent state under the elastic force of the elastic plate 1 itself. At this time, under the pulling action of the adhesive component 5, the skin on both sides of the opening is brought closer, and the skin on both sides of the incision is brought closer, so as to speed up the healing of the wound at the incision.

[0035] It should be noted that when the two movable plates 4 move, the fixed tube 61 moves accordingly, and sliding occurs between the sleeve 63 and the through tube 62, ensuring that the two movable plates 4 can only move along the front-rear direction.

[0036] Specifically, Figures 1 to 5 As shown, a small groove 64 is provided at the rear end of the ring side of the sleeve 63, a flexible membrane 65 is fixedly connected to the inner wall of the small groove 64, a clamping hole 66 is provided inside the sleeve 63 near the small groove 64, a push rod 67 is fixedly connected to one side of the flexible membrane 65 near the clamping hole 66, and a spring push pin 68 is provided at the outer rear end part of the through tube 62.

[0037] By adopting the above technical solution, when the two movable plates 4 are manually pressed to move the two movable plates 4 in a direction approaching each other, sliding occurs between the sleeve 63 and the through tube 62 until a part of the spring ejector pin 68 reaches the position of the clamping hole 66, and the ejector pin part of the spring ejector pin 68 is inserted into the inside of the clamping hole 66, thereby limiting the sleeve 63 and the through tube 62, so that the movable plate 4 is limited and the elastic plate 1 remains in a relatively bent state.

[0038] After the operation is completed, by pressing the flexible membrane 65 inside the small groove 64, the push rod 67 moves to squeeze the spring push pin 68, thereby canceling the limit on the sleeve 63 and the through tube 62, and under the elastic force of the elastic plate 1 itself, the elastic plate 1 returns to the initial slightly bent state.

[0039] The traditional zipper-type skin traction device is not conducive to surgical operation because the limiting zipper part is located above the incision when pulling the skin. The design of this solution makes the components used for limiting when pulling the skin located on both sides of the incision, which does not affect the doctor's debridement operation at the incision.

[0040] It should be noted that the spring ejector 68 belongs to the mature existing technology, and is composed of an elastic part and an ejector part, which will not be described in detail.

[0041] Specifically, Figures 2 to 5 As shown, the pasting assembly 5 includes an elastic rope 51 fixedly connected to the bottom of the elastic plate 1, and a plurality of elastic ropes 51 are provided, and the bottom of the elastic rope 51 is fixedly connected to the pasting plate 52.

[0042] By adopting the above technical solution, a plastic film can be pasted on the bottom of the plurality of adhesive plates 52 to protect the glue at the adhesive plates 52 during transportation. When the elastic plate 1 is bent, the elastic rope 51 and the adhesive plates 52 pull the skin. The elastic rope 51 has a certain elasticity and can generate uniform pulling force when pulling the skin, thereby improving the effect of pulling the skin.

[0043] Specifically, Figures 2 to 4 and Figures 5 to 8As shown, the left and right side parts of the two moving plates 4 close to one end are both provided with a pushing assembly 8, and the pushing assembly 8 includes a moving rod 81 slidably connected to the middle part of the fixed cylinder 61, and the moving rod 81 is fixedly connected to a first piston plate 82 on the side close to the moving plate 4, and the outer side of the first piston plate 82 fits with the inner part of the fixed cylinder 61, and the inner end of the fixed cylinder 61 away from the moving plate 4 is fixedly connected with a corrugated bag 83, and the pushing assembly 8 includes a moving groove 84 opened in the sliding seat 2 near the side of the fixed cylinder 61, and a second piston plate 85 is provided inside the moving groove 84, and a small rod 86 is fixedly connected between the second piston plate 85 and the small block 3, and the outer wall of the second piston plate 85 fits with the inner side of the moving groove 84, and a round tube 87 is fixedly inserted between the corrugated bag 83 and the moving groove 84, and the front end of the moving rod 81 at the rear end is fixedly connected to the through-tube 62, and the moving rod 81 at the rear end is fixedly connected to the through-tube 62. The rear end of the moving rod 81 at the end is fixedly connected with a bent frame 89, and the end of the bent frame 89 away from the moving rod 81 at the rear end is fixedly connected to the sleeve 63, and the outer wall of the bent frame 89 is slidably connected to the through tube 62, and a groove 88 is provided inside the sliding seat 2 near the small block 3, and the outer side of the small block 3 is slidably connected to the inside of the groove 88, and an empty groove 810 is provided inside the sliding seat 2 on the side of the moving groove 84 away from the elastic plate 1, and the inner wall of the empty groove 810 is fixedly connected with an elastic membrane 811, and the top of the sliding seat 2 is movably connected with a movable rod 9, and an easy-to-break plastic 10 is fixedly connected between the movable rod 9 and the sliding seat 2. The easy-to-break plastic 10 is a commonly used prior art technology, and its diameter is small, and it can be torn off by force, and no further elaboration is made. The elastic force of the elastic plate 1 itself is greater than twice the sum of the elastic force of the elastic membrane 811 and the elastic force of the corrugated bag 83, and a liquid medium is arranged inside the corrugated bag 83.

[0044] By adopting the above technical solution, when the device is not in use, under the elastic force of the elastic plate 1 itself, the two movable plates 4 are in a state of being separated from each other. At this time, the sleeve 63 and the through tube 62 are separated from each other, and the first piston plate 82 squeezes the corrugated bag 83, so that the liquid medium inside the corrugated bag 83 enters the inside of the circular tube 87, and enters the inside of the movable groove 84 from the inside of the circular tube 87. At this time, under the action of the movable rod 9, the small block 3 cannot slide inside the slide 2, and the elastic force of the elastic membrane 811 in the empty groove 810 is greater than the resistance of the movement of the second piston plate 85. When the medium in the corrugated bag 83 enters the inside of the movable groove 84, since the small block 3 is limited and cannot slide inside the slide 2 at this time, the medium squeezes the elastic membrane 811, causing the elastic membrane 811 to deform.

[0045] Since the present solution uses an elastic rope 51 and an adhesive plate 52 to pull the skin, the elastic rope 51 has a certain elasticity and can generate uniform pulling force when pulling the skin. However, due to the flexible characteristics of the elastic rope 51, it will affect the close contact of the skin at the incision to a certain extent. Therefore, the present solution provides a pushing component 8. When the two movable plates 4 are close to each other, the movable rod 81 and the first piston plate 82 move in the direction of the first piston plate 82. At this time, the corrugated bag 83 is not squeezed. When the wound needs to be sutured after the operation, the limiting component 6 cancels the limiting of the sleeve 63 and the through tube 62. Under the elastic force of the elastic plate 1 itself, the two movable plates 4 move away from each other. At this time, the sleeve 63 and the through tube 62 move away from each other, so that the movable rod 81 and the first piston plate 82 move away from the first piston plate 82. The first piston plate 82 moves in the direction of the first piston plate 82, so that the first piston plate 82 squeezes the corrugated bag 83, so that the liquid medium inside the corrugated bag 83 enters the inside of the circular tube 87, and enters the inside of the movable groove 84 from the inside of the circular tube 87. At this time, the movable rod 9 is pulled upward to break the fragile plastic 10 and pull out the movable rod 9. Since the elastic force of the elastic membrane 811 is greater than the resistance of the movement of the second piston plate 85, under the action of the liquid pressure inside the movable groove 84, the small rod 86 moves with the small block 3 in the groove 88 in the direction away from the small rod 86, so that the two elastic plates 1 move in the direction of approaching each other as a whole, compensating for the skin adhesion effect affected by the flexibility of the elastic rope 51, further facilitating the skin adhesion at the opening, and improving the effect of skin pulling.

[0046] It should be noted that the outer side of the small block 3 can be rotatably connected with a ball for reducing the friction generated during movement.

[0047] Specifically, Figures 2 to 9 As shown, a deceleration assembly 7 is arranged between the two fixed cylinders 61 on the same side, and the deceleration assembly 7 includes a deceleration plate 71 fixedly connected to the bottom of the through-tube 62, and a slot 72 is provided at the bottom of the deceleration plate 71. The deceleration assembly 7 also includes an arc plate 73 fixedly connected to the bottom of the bending frame 89, and an elastic strip 74 is fixedly connected to the inner side of the arc plate 73 away from the bending frame 89, and the front end of the slot 72 is inclined.

[0048] By adopting the above technical solution and the design of the bent frame 89, when the two movable plates 4 approach each other, the bent frame 89 moves close to the movable plate 4 at the front end, so that the movable rod 81 and the first piston plate 82 at the front end move toward the front end, and the bent frame 89 ensures that the through tube 62 and the sleeve 63 will not rotate.

[0049] Furthermore, when the limiting component 6 cancels the limiting of the through tube 62 and the sleeve 63, the through tube 62 and the sleeve 63 slide rapidly under the elastic force of the two elastic plates 1 themselves, and the deceleration component 7 can slow down the speed of relative movement of the through tube 62 and the sleeve 63, thereby avoiding the skin being pulled at a faster speed when the two elastic plates 1 are quickly restored, thereby reducing damage to the wound.

[0050] When the through tube 62 and the sleeve 63 slide relative to each other, the elastic strip 74 fixedly connected to the arc plate 73 approaches the slot 72 opened on the deceleration plate 71. During this process, the elastic strip 74 extends from the front end of the deceleration plate 71 to the rear end of the deceleration plate 71. Since the rear end of the slot 72 is not inclined, the elastic strip 74 cooperates with the slot 72 to slow down the relative movement speed of the through tube 62 and the sleeve 63.

[0051] When the two moving plates 4 are manually pressed to move closer to each other, since the front end of the slot 72 is inclined, the elastic strip 74 can easily reach the other slot 72 from one slot 72, thereby reducing the force required for pressing.

[0052] Working principle: The adhesive component 5 arranged at the bottom of the two elastic plates 1 is pasted on the skin of the patient's debridement area. The doctor can use a scalpel to make an opening at the position between the two elastic plates 1. After the opening, the movable plates 4 at the front and rear ends are manually pressed to make the two movable plates 4 move in the direction of approaching each other, so that the slide seat 2 and the small block 3 at the front and rear ends move, so that the elastic plate 1 can be placed in a bent state, so that the adhesive component 5 pulls the skin, thereby playing a role in stretching the skin of the incision part, which is convenient for the doctor to perform the debridement operation. When the skin is pulled to stretch the incision, the elastic plate 1 is at the In a bent state, the cutting edge is in a relatively round state, so that the doctor can clearly see the depth, range and nature of the wound, which is convenient for the doctor to perform debridement surgery and better perform debridement and excision surgery, thereby improving the effect of pulling the skin to open the incision. When opening, the limiting effect of the two movable plates 4 is cancelled by the limiting component 6. Under the elastic force of the elastic plate 1 itself, the elastic plate 1 can return to the initial slightly bent state. At this time, under the pulling effect of the adhesive component 5, the skin on both sides of the incision is brought closer, so as to speed up the healing of the wound at the incision.

[0053] In the conventional zipper-type skin traction device, the zipper part for limiting when pulling the skin is located above the incision, which is not conducive to the operation of the operation. The design of this solution makes the components used for limiting when pulling the skin be located on both sides of the incision, which does not affect the doctor's debridement operation at the incision. When the elastic plate 1 is bent, the elastic rope 51 and the adhesive plate 52 pull the skin. The elastic rope 51 has a certain elasticity and can generate uniform pulling force when pulling the skin, thereby improving the effect of skin traction. When the wound needs to heal after the operation, the limiting component 6 cancels the limiting of the sleeve 63 and the through-tube 62. Under the elastic force of the elastic plate 1 itself, the two movable plates 4 move away from each other. At this time, the sleeve 63 and the through-tube 62 move away from each other, so that the movable rod 81 and the first piston plate 82 move away from the direction of the first piston plate 82, so that the first piston plate 82 squeezes the corrugated bag 83, so that the liquid medium inside the corrugated bag 83 enters the inside of the circular tube 87 and flows out from the circular tube 87. The inside of the movable groove 84 enters the inside of the movable groove 84, and the movable rod 9 is pulled upward at this time, so that the plastic at one end breaks and the movable rod 9 is pulled out. Since the elastic force of the elastic membrane 811 is greater than the resistance to the movement of the second piston plate 85, under the action of the liquid pressure inside the movable groove 84, the small rod 86 moves with the small block 3 in the groove 88 in the direction away from the small rod 86, thereby making the two elastic plates 1 move in the direction of approaching each other as a whole, compensating for the skin adhesion effect affected by the flexibility of the elastic rope 51, further facilitating the skin adhesion at the opening, and improving the effect of skin pulling. When the limiting component 6 cancels the limiting of the penetration tube 62 and the sleeve 63, under the action of the elastic force of the two elastic plates 1 themselves, the penetration tube 62 and the sleeve 63 slide rapidly, and under the action of the deceleration component 7, the speed of relative movement of the penetration tube 62 and the sleeve 63 can be slowed down, thereby avoiding the rapid recovery of the two elastic plates 1 and pulling the skin at a faster speed, thereby reducing damage to the wound.
