Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a skin flap blood supply occluder. Background Art

[0002] Currently, in the medical field, in some cases, the skin may be severely injured and cause skin soft tissue defects, and important tissues such as tendons or bone joints deep in the skin are exposed. In this case, a pedicled skin flap transplant is needed to repair the defective wound. The re-transplanted skin flap is connected to the pedicle of the skin source on the body to gradually establish blood circulation for the skin defect. After a period of time after the operation, when the moved skin can supply blood on its own, a pedicle-cutting operation can be performed.

[0003] There are many existing technologies for blockers, such as:

[0004] Chinese patent publication number CN215424886U discloses an adjustable blood flow blocker for use before pedicle cutting after skin flap surgery, which includes a first clamping rod, a second clamping rod, a first connecting screw and a second connecting screw. The two ends of the first clamping rod are connected by the first connecting screw and the second connecting screw respectively. In this way, according to the shape and size of the pedicle connecting part, the spacing between the two sides of the first clamping rod and the second clamping rod can be adjusted at the same time, so that the clamping degree of the pedicle connecting part is more uniform and the adjustment is more convenient. In addition, a first scale and a second scale are respectively provided at the two ends of the first clamping rod, and a marking line is respectively provided at the end of the first connecting screw and the second connecting screw. In this way, in the process of twisting the first connecting screw and the second connecting screw, the position of the marking line on the first scale or the second scale can be observed, so that the adjustment of the spacing between the two sides of the first clamping rod and the second clamping rod is controllable, so that the clamping force applied to the pedicle connecting part is relatively controllable.

[0005] It can be seen that most of the blockers clamp the pedicle through the distance between the first clamping rod and the second clamping rod to achieve the effect of blood flow blocking, but during use, it is necessary to operate the connecting screws on both sides, which not only reduces the stability of clamping, causes clamping imbalance, and affects the clamping effect, but also reduces the work efficiency of the blocker, causing a waste of time, and requires excessive physical strength, reducing the practicality of the blocker. Moreover, before using the blocker, it is inevitable that dust or debris will adhere to the side of the clamping rod close to the pedicle, which can easily cause infection, increase the risk of pedicle cutting surgery, and thus reduce the safety of the use of the blocker.

[0006] In view of this, we proposed a flap blood supply devascularization device. Summary of the invention

[0034] Example

[0035] See also Figure 1-Figure 7As shown, the present embodiment aims to provide a flap blood supply occluder, comprising a base 10, wherein the upper surface of the base 10 is provided with a pad 12 for padding the pedicle portion, and the interior of the base 10 is provided with a lifting assembly 11, wherein the upper end of the lifting assembly 11 extends out of the surface of the pad 12, and the interior of one side of the lifting assembly 11 is movably connected with a clamping member 20 through a hinge, and the end of the clamping member 20 away from the hinge is plugged into the interior of the other side of the lifting assembly 11 through a plug-in assembly 30, wherein: the lifting assembly 11 can adjust the position of the clamping member 20, and assist the clamping member 20 to align with the pad 12 The connecting pedicle part performs clamping work, and the clamping member 20 at least includes a mounting frame 201, and the lower surface of the inner wall of the mounting frame 201 is provided with a clamping plate 202; the two sides of the mounting frame 201 are movably connected with a protection component 21 through an automatic reset hinge, and the protection component 21 can protect the clamping member 20, and the inner wall of the mounting frame 201 close to the plug-in component 30 is provided with a propping component 22; the plug-in component 30 is used to stably install the clamping member 20 and the lifting component 11, and when the clamping member 20 and the lifting component 11 are installed, it can drive the propping component 22 to work, so as to open the protection component 21.

[0036] First, the specific structure of the lifting assembly 11 is disclosed. The lifting assembly 11 at least includes a mounting plate 111. The mounting plate 111 is arranged inside the base 10. The upper surface of the mounting plate 111 is provided with a starter 112. The starter 112 includes two gears and a rack belt. The two gears are meshed and connected by a rack belt, and the lower part of one of the gears is coaxially connected to the output shaft of the motor. Both ends of the upper surface of the starter 112 penetrate the pad 12 and are coaxially connected to the screw rod 113. The two ends of the upper surface of the pad 12 are connected to the screw rod 113. A support rod 114 is provided on both sides, and a top plate 115 is provided on the upper surface of the support rod 114. The lower surface of the top plate 115 is rotatably connected to the end of the screw rod 113. The outer wall of the screw rod 113 is threadedly connected to a movable plate 116. The two movable plates 116, one end of which is away from the support rod 114, is movably connected to the end of the lower surface of the mounting frame 201 through a hinge, and the upper surface of the other movable plate 116 is plug-fitted with the side of the lower surface of the mounting frame 201 away from the hinge through a plug-in assembly 30.

[0037] The improvement lies in: connecting the motor to power to make it work, rotating the motor output shaft clockwise to make one of the gears rotate, and through the meshing connection, the rack belt drives the two gears to rotate synchronously, so that the two screw rods 113 rotate clockwise at the same time, and the movable plate 116 on the screw rod 113 is close to the top plate 115. At this time, the connecting pedicle part can be placed on the upper surface of the pad 12, and the clamping piece 20 is plugged in and matched through the plug-in assembly 30, and then the motor output shaft is rotated counterclockwise to make the screw rod 113 rotate counterclockwise as well, and the movable plate 116 is close to the pad 12, so that the clamping plate 202 clamps the connecting pedicle part. This not only has simple operation, but also improves the working efficiency of the blocker and avoids time waste, but also improves the balance of the clamping piece 20 on the connecting pedicle part, improves the stability of the blocker, and thus improves the safety of the blocker.

[0038] Secondly, the specific structure of the protection component 21 is disclosed. The protection component 21 at least includes a protection plate 211. The upper ends of both sides of the mounting frame 201 are movably connected with the protection plate 211 through automatic reset hinges. The lower surface of the protection plate 211 is provided with a sealing plate 212, and the sealing plate 212 is made of elastic material.

[0039] The improvement lies in that: the splint 202 is sealed by two protective plates 211, and the lower surface of the splint 202 is sealed by a sealing plate 212, so as to reduce the adhesion of dust or debris to the lower surface of the splint 202 and prevent infection. Moreover, there are many parts between the clamping member 20 and the movable plate 116, which are above the pedicle part, which may easily cause parts failure. Therefore, the protection of the clamping member 20 by the protective plate 211 and the sealing plate 212 can reduce the frequency of blocker failure, thereby increasing the service life of the blocker. On the contrary, the pad 12 has a simple structure and can be wiped with alcohol below the pedicle part to achieve an infection-proof effect without causing parts failure. Moreover, the sealing plate 212 is made of elastic material, so as to avoid affecting the normal use of the splint 202 after the sealing plate 212 is stretched open, thereby avoiding secondary injury to the patient and economic loss.

[0040] The specific structure of the plug-in assembly 30 is disclosed again. The plug-in assembly 30 at least includes a plug-in plate 31 and a slot 32. The slot 32 is provided on the side of the lower surface of the mounting frame 201 away from the hinge, and the upper surface of the movable plate 116 away from the clamping member 20 is provided with a plug-in plate 31 for plugging with the slot 32. The two sides of the upper surface of the plug-in plate 31 are arc-shaped, and a reinforcement assembly 33 is provided inside the plug-in plate 31.

[0041] The improvement lies in: holding the handle tightly and flipping the mounting frame 201, the plug plate 31 can be plugged into the slot 32 through the arcs on both sides of the upper surface of the plug plate 31, preventing the plug plate 31 from being too high and affecting the plugging of the plug plate 31 and the slot 32, playing an auxiliary rotation, and at the same time, it also pushes the support component 22, and increases the stability of the plugging and matching between the plug plate 31 and the slot 32 through the reinforcement component 33, preventing the plug plate 31 and the slot 32 from being disconnected during the clamping process of the clamp 20, effectively improving the safety of the use of the clamp 20, avoiding medical accidents, and also improving the stability of the use of the blocker, thereby improving the use effect of the blocker.

[0042] Then, the specific structure of the reinforcement component 33 is disclosed. The reinforcement component 33 at least includes a multi-stage cylinder 331. The multi-stage cylinder 331 is arranged inside the side opening of the plug plate 31, and the piston rod of the multi-stage cylinder 331 is provided with a reinforcement plate 332.

[0043] The improvement lies in: connecting the multi-stage cylinder 331 to a power source to make it work, and through the pushing work of the piston rod of the multi-stage cylinder 331, the reinforcement plate 332 is inserted into the interior of the support component 22, which not only increases the stability of the plug-in fit between the plug plate 31 and the slot 32, but also assists the support component 22 in opening the protection component 21, thereby improving the working efficiency of the blocker, reducing time consumption, and thus improving the safety of the blocker.

[0044] Finally, the specific structure of the support component 22 is disclosed. The support component 22 at least includes an installation groove 221. The interior of the slot 32 is provided with the installation groove 221. The interior of the installation groove 221 is provided with a first elastic member 222. A movable frame 223 is provided at the other end of the first elastic member 222. A connecting block 224 is provided in the middle of the inner wall of the movable frame 223. Second elastic members 225 are provided on both sides of the connecting block 224. A support plate 226 is provided on the side of the second elastic member 225 away from the connecting block 224. A limiting axis 227 is provided on the side of the support plate 226 close to the connecting block 224. The limiting axis 227 is located inside the second elastic member 225.

[0045] The improvement lies in that: the stability of the insertion of the plug plate 31 and the slot 32 is increased by the reinforcement component 33. At the same time, the movable frame 223 is moved out of the interior of the installation groove 221, and the first elastic member 222 is deformed and elongated. At this time, the support plate 226 loses the restriction of the inner wall of the installation groove 221. The support plate 226 is ejected from the interior of the movable frame 223 through the resilience of the second elastic member 225, and the protection plate 211 is moved to both sides of the installation frame 201, and the spring on the automatic reset hinge is also deformed. At the same time, the limiting shaft 227 limits the elastic force of the second elastic member 225, thereby increasing the stability of the use of the support component 22. Not only is the operation simple, but the protection component 21 is also opened while the clamping member 20 is plugged in, which does not affect the normal use of the clamping member 20, thereby improving the flexibility of the use of the blocker, and also improving the stability of the position fixation of the clamping member 20, thereby improving the safety of the use of the blocker, avoiding medical accidents, thereby improving the practicality of the blocker, and avoiding economic losses.

[0046] Considering that after the plug-in assembly 30 is disconnected, the mobile frame 223 will be moved toward the interior of the installation groove 221 through the rebound force of the first elastic member 222, and the auxiliary support plate 226 will enter the interior of the mobile frame 223 through the outer wall of the installation groove 221. At the same time, the second elastic member 225 also needs to be deformed and contracted. Therefore, the support plate 226 presents an isosceles triangle, and the sharp corner of the support plate 226 is arc-shaped.

[0047] The improvement lies in that: through the inclination of the hypotenuse of the support plate 226, the outer wall of the installation groove 221 can apply resistance according to the hypotenuse of the support plate 226, so that the movable frame 223 can quickly enter the interior of the installation groove 221, which is convenient for opening the blocker. It is not only simple to operate, but also improves the work efficiency of the blocker, reduces time consumption, and improves the flexibility of the blocker. The arc at the sharp corner of the support plate 226 can avoid damage to the protective plate 211, thereby increasing the service life of the blocker.

[0048] Since the pad 12 and the clamp 202 clamp the pedicle tissue, in order to reduce the damage to the pedicle tissue, the arc surface of the upper surface of the pad 12 and the lower surface of the clamp 202 are made of soft medical grade materials.

[0049] The improvement lies in that the position of the splint 202 is moved by the lifting component 11, so that the soft medical-grade material fits the pedicle tissue, effectively protecting the pedicle tissue, reducing damage to the pedicle tissue, and reducing the patient's pain, thereby improving the practicality of the occluder.

[0050] In summary, the working principle of this scheme is as follows: first, the motor is powered on to make it work, and the motor output shaft is rotated clockwise to make one of the gears rotate, and through the meshing connection, the rack belt drives the two gears to rotate synchronously, so that the two screw rods 113 rotate clockwise at the same time, and the movable plate 116 on the screw rod 113 is moved closer to the top plate 115. At this time, the connecting pedicle part can be placed on the upper surface of the pad 12, and then the handle is gripped and the mounting frame 201 is turned over to make the plug plate 31 and the slot 32 be plugged in and matched, and the multi-stage cylinder 331 is powered on to make it work, and the piston rod of the multi-stage cylinder 331 pushes the reinforcing plate 332 to be inserted into the interior of the support assembly 22, At the same time, the movable frame 223 is moved out of the installation groove 221, and the first elastic member 222 is deformed and elongated. At this time, the support plate 226 loses the restriction of the inner wall of the installation groove 221, and the support plate 226 is ejected from the inside of the movable frame 223 through the resilience of the second elastic member 225, and the protection plate 211 is moved to both sides of the installation frame 201, and the spring on the automatic reset hinge is also deformed. At the same time, the limiting shaft 227 limits the elastic force of the second elastic member 225. Then, the motor output shaft is rotated counterclockwise, so that the screw rod 113 is also rotated counterclockwise, and the movable plate 116 is moved closer to the pad 12, so that the clamping plate 202 clamps the pedicle part, and the work of clamping the blocker is completed;

[0051] When it is necessary to end the use of the blocker, first, the motor output shaft is rotated clockwise, so that the two screw rods 113 are rotated clockwise at the same time, and the movable plate 116 on the screw rod 113 is moved closer to the top plate 115. At this time, the reinforcing plate 332 is moved to the inside of the plug plate 31 through the reset work of the piston rod of the multi-stage cylinder 331, and then the handle is held tightly to flip the mounting frame 201 to disconnect the plug plate 31 from the slot 32. At the same time, through the resilience of the first elastic member 222, the outer wall of the mounting groove 221 can apply resistance according to the hypotenuse of the support plate 226, so that the movable frame 223 can quickly enter the interior of the mounting groove 221, and the second elastic member 225 also deforms and shrinks, and through the reset work of the automatic reset hinge, the protective plate 211 protects the splint 202. At this time, the blocker can be detached from the pedicle part, and the use of the blocker can be completed.
