Description

Technical Field

[0001] This invention relates to the field of medical suturing equipment technology, specifically to an adjustable skin wound suturing device for livestock pathological sampling. Background Technology

[0002] Animal pathological sampling is a crucial step in animal disease diagnosis, monitoring, epidemiological investigation, and scientific research. The standardization of its operation directly affects the accuracy of the test results. In animal pathological sampling or wound treatment, skin wound suturing is a key operation to promote wound healing, prevent infection, and restore tissue function. In animal skin wound suturing, appropriate equipment and tools are crucial to ensuring suturing quality and reducing animal stress and infection risks. A common suturing device is a disposable skin stapler, a medical device used to replace manual sutures. Its working principle is similar to a stapler, mainly using titanium or stainless steel staples to anastomose tissues.

[0003] When suturing a wound by inserting sutures, the sutures are obstructed during insertion, causing the sides of the sutures to bend inwards and insert into the skin. When the device is lifted, the sutures may not be able to come out, resulting in the sutures tearing the skin at the wound site. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An adjustable skin wound suturing device for livestock pathological sampling includes:

[0006] A base plate, on the top of which a fixed cover is fixedly installed, and an end cover is fixedly installed at one end of the fixed cover. A plate groove is opened on the top of the fixed cover.

[0007] A pinning mechanism, which is fixedly installed on the top of the fixing cover;

[0008] A push-nail mechanism is installed at the center of the top of the base plate and inside the fixing cover;

[0009] A groove is formed at the center of the outer side of the end cover, and side plates are symmetrically arranged on the side of the end cover near the fixed cover. The non-opposing surfaces of the side plates are tightly fitted to the inner wall of the fixed cover. A rotating block is fixedly installed at the center of the outer side of the end cover, and a screw is rotatably installed on the inner wall of the rotating block. A sliding plate is slidably installed at the groove of the end cover. The sliding plate is symmetrically installed at the center of the axis of the end cover, and the inner wall of the sliding plate is threaded to the outer side of the screw. A stop bar is slidably installed on the inner wall of the sliding plate. The end of the stop bar away from the sliding plate is an inclined surface that slopes from top to bottom towards the side of the sliding plate. The device is connected to the sliding plate by a screw. The position of the stop bar can be adjusted according to the skin thickness at the suture location, and the bending depth on both sides when the tack is inserted can be adjusted to regulate the suture depth. At the same time, the inclined surface at the end of the stop bar away from the sliding plate is used to press down the top of the tack when the device is lifted at the suture location. This prevents the tack from being unable to disengage after being inserted and prevents the stop bar from still blocking the tack, which would cause the suture location to be pulled when lifted. A conical block is fixedly installed on the outside of the stop bar, and a first spring is fixedly installed between the conical block and the end cover.

[0010] Preferably, the outer diameter of the conical block gradually increases as it approaches the end cover. A nail stop plate is fixedly installed on the opposite side of the side plate away from the end cover. The nail stop plate blocks the nails and restricts the nails to be inserted, preventing misalignment. At the same time, it guides the nails as they move downward, ensuring they move vertically under pressure. This prevents the nails from shifting internally when they bend at both ends, thus preventing them from being inserted into the skin for suturing. The side of the nail stop plate away from the end cover is flat, and the nail stop plate is located outside the stop bar.

[0011] Preferably, the pressing mechanism includes a fixed handle, the bottom of which is fixedly connected to the center of the top of the fixed cover, and both ends of the fixed handle are provided with sliding grooves. A top pressure plate is installed on the top of the fixed handle, and both ends of the inner wall of the top pressure plate are slidably adapted to the sliding grooves of the fixed handle. An elastic ring is fixedly installed between the top pressure plate and the fixed handle. A side clamping plate is fixed on the top of the fixed handle, and the side clamping plate is symmetrically installed along the center of the axis of the fixed handle.

[0012] Preferably, the opposite surfaces of the side plates are tightly fitted to the outer side of the elastic ring. A pressure plate is fixedly installed at the bottom of the fixed handle, and the outer side of the pressure plate is slidably adapted to the groove of the fixed cover. A pressure groove is formed at the bottom of the pressure plate, and both sides of the pressure groove are inclined surfaces that slope outward from top to bottom. Through the cooperation of the pressure groove and the inclined surfaces of the pressure plate, when pressing down the nail, pressure is first applied to both sides of the top of the nail, so that the nail can bend smoothly into the skin under the obstruction of the stop bar when it is driven in. The inclined surface at the bottom of the pressure plate near the nail pushing mechanism pushes the remaining nails away from the end cover after pressing down one nail, thus avoiding pressure during driving. The pressure plate has multiple tacks, and the bottom of the pressure plate near the pusher mechanism is an inwardly sloping surface from top to bottom. A zigzag plate is fixedly installed on the side of the pressure plate near the end cover. Utilizing the arc-shaped protrusion of the zigzag plate, when the tack is pressed down, as the tack bends, the arc-shaped protrusion of the zigzag plate gradually contacts the conical block, compressing the first spring and pushing the stop bar. After the stop bar moves to a certain extent, it stops obstructing the tack, allowing the tack to be smoothly inserted into the skin wound. At the same time, the zigzag plate causes the stop bars on both sides to move synchronously, preventing one side from still obstructing the tack and causing it to be unable to dislodge. The bottom of the zigzag plate is provided with an arc-shaped protrusion, and the zigzag plate is located directly above the conical block.

[0013] Preferably, the push-nail mechanism includes a hollow grooved plate, the bottom of which is fixedly connected to the center of the top of the base plate, and a groove is formed at the center of the top of the hollow grooved plate. A sliding hole block is slidably installed in the groove of the hollow grooved plate, a push-nail block is fixedly installed on the top of the sliding hole block, and a nail-holding plate is fixedly installed on the top of the push-nail block. The side of the nail-holding plate near the end cover is an inwardly inclined surface from top to bottom. By utilizing the inwardly inclined surface of the nail-holding plate near the end cover, in cooperation with the nail-pressing mechanism, the nail is restricted at the other end when the nail is driven in, so as to prevent the remaining nails from tilting or lifting inside when the nail is driven in, which would cause the remaining nail group to break and cause blockage inside.

[0014] Preferably, an inner sliding rod is slidably installed on the inner wall of the sliding hole block, a fixing block is fixedly installed at the end of the inner sliding rod away from the sliding hole block, and an inner locking block is fixedly installed on the outside of the fixing block. A second spring is fixedly installed between the inner locking block and the sliding hole block. The second spring is located on the outside of the inner sliding rod. Arc-shaped protrusions are provided on both sides of the inner locking block, and protrusions are provided on both sides of the inner wall of the fixing cover. The inner locking block engages with the protrusions of the fixing cover through the arc-shaped protrusions.

[0015] This invention provides an adjustable skin wound suturing device for livestock pathological sampling. It has the following beneficial effects:

[0016] I. The adjustable skin wound suturing device used for livestock pathological sampling, through the threaded connection between the screw and the sliding plate, allows for adjustment of the position of the stop bar according to the skin thickness at the suturing site, thereby adjusting the bending depth on both sides when inserting the suture nail and adjusting the suturing depth. At the same time, by utilizing the inclined surface at the end of the stop bar away from the sliding plate, when the device is lifted at the suture position, the movement of the stop bar during resetting, in conjunction with the inclined surface, presses down on the top of the suture nail, preventing the suture position from being pulled when the suture is lifted if the suture nail cannot be dislodged after resetting.

[0017] 2. The adjustable skin wound suturing device used for pathological sampling of livestock uses a nail stop to block the nails and restrict the nails to be inserted, preventing misalignment during insertion. At the same time, it guides the nails as they move downward, ensuring that the nails move vertically downward under pressure. This prevents the nails from shifting internally when they bend at both ends, which would prevent them from being inserted into the skin for suturing.

[0018] 3. The adjustable skin wound suturing device used for pathological sampling of livestock uses the groove and bevel of the pressure plate to apply pressure to both sides of the top of the nail when pressing down the nail, so that the nail can bend and be inserted into the skin smoothly under the obstruction of the stop bar. The bevel at the bottom of the pressure plate near the nail pushing mechanism pushes the remaining nails away from the end cover after pressing down one nail, thus avoiding pressing out too many nails when driving them in.

[0019] IV. The adjustable skin wound suturing device used for pathological sampling of livestock uses the curved convex strip of the zigzag plate. When the nail is pressed down, as the nail bends, the curved convex strip of the zigzag plate gradually compresses the first spring by contacting the conical block, pushing the stop bar. After the stop bar moves to a certain extent, it stops obstructing the nail, allowing the nail to be smoothly driven into the skin wound. At the same time, the zigzag plate causes the stop bars on both sides to move synchronously, preventing one side from still obstructing the nail and causing it to be unable to come off.

[0020] 5. The adjustable skin wound suturing device used for animal pathological sampling uses a sloping plate that is inclined from top to bottom and inward on the side near the end cover. This works in conjunction with the nail pressing mechanism to restrict the nail at the other end when the nail is driven in. This prevents the remaining nail from tilting or lifting up inside the nail during driving in, which could lead to breakage of the remaining nail group and cause blockage inside the nail.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1, as Figures 1 to 5 As shown, the present invention provides a technical solution:

[0033] An adjustable skin wound suturing device for livestock pathological sampling includes:

[0034] The base plate 5 has a fixed cover 1 fixedly installed on its top. An end cover 4 is fixedly installed on one end of the fixed cover 1. A plate groove is opened on the top of the fixed cover 1.

[0035] The nail-pressing mechanism 2 is fixedly installed on the top of the fixed cover 1;

[0036] The push-nail mechanism 3 is installed at the center of the top of the base plate 5 and is installed inside the fixing cover 1;

[0037] A groove is provided at the center of the outer side of the end cover 4, and side plates are symmetrically arranged on the side of the end cover 4 near the fixed cover 1. The non-opposing surfaces of the side plates are tightly fitted to the inner wall of the fixed cover 1. A rotating block 10 is fixedly installed at the center of the outer side of the end cover 4. When the nail is driven in, the pressure of the nail pressing mechanism 2 causes the nail closest to the nail stop plate 7 to be pressed down and driven into the skin on both sides of the wound. At the same time, during the downward movement of the nail, the nail is blocked by the stop bar 6, so that when the nail is driven into the skin, the nail heads on both sides bend inward and obliquely insert into the skin on both sides. A screw 12 is rotatably installed on the inner wall of the rotating block 10, and a sliding plate 11 is slidably installed at the groove of the end cover 4. The sliding plate 11 is symmetrically installed at the center of the axis of the end cover 4. Before nailing, the screw 12 can be rotated according to the skin suture depth, and the screw 12 and the sliding plate 11 are used to make the nail sinker. The threaded connection allows the sliding plate 11 to slide in the groove of the end cover 4, driving the stop rod 6. The stop rod 6 is adjusted according to the insertion depth. The inner wall of the sliding plate 11 is threadedly connected to the outer side of the screw 12. The stop rod 6 is slidably installed on the inner wall of the sliding plate 11. The end of the stop rod 6 away from the sliding plate 11 is an inclined surface that slopes from top to bottom towards the side of the sliding plate 11. After the skin nail is inserted into the skin, the pressing mechanism 2 and the conical block 8 cooperate to drive the stop rod 6 through the conical block 8, compressing the first spring 9. This causes the stop rod 6 to slide on the inner wall of the sliding plate 11, stopping the obstruction of the downward movement of the skin nail. The top of the skin nail reaches below the stop rod 6 under the action of the pressing mechanism 2, completing the suture. Then the pressing mechanism 2 resets and the stop rod 6 resets. The conical block 8 is fixedly installed on the outer side of the stop rod 6. The first spring 9 is fixedly installed between the conical block 8 and the end cover 4.

[0038] The outer diameter of the conical block 8 gradually increases as it approaches the end cover 4. A stop plate 7 is fixedly installed on the side of the opposite side of the side plate away from the end cover 4. The side of the stop plate 7 away from the end cover 4 is flat, and the stop plate 7 is located outside the stop bar 6.

[0039] Example 2, based on Example 1, please refer to... Figures 6 to 7As shown, the pinning mechanism 2 includes a fixed handle 21. The bottom of the fixed handle 21 is fixedly connected to the center of the top of the fixed cover 1. Both ends of the fixed handle 21 are provided with sliding grooves. When using the fixed handle 21, the top pressure plate 22 is pressed by applying pressure to the top pressure plate 22 when the pin is inserted for sewing. This causes the top pressure plate 22 to deform close to the fixed handle 21 and compress the elastic ring 23. As the top pressure plate 22 moves down, it drives the pinning plate 24 down, allowing the pinning plate 24 to slide down in the groove of the fixed cover 1. The bottom groove of the pinning plate 24 contacts the top of the pin, causing the pin to move down. The top pressure plate 22 is installed on the top of the fixed handle 21. Both ends of the inner wall of the top pressure plate 22 are slidably adapted to the sliding groove of the fixed handle 21. An elastic ring 23 is fixedly installed between the top pressure plate 22 and the fixed handle 21. The top of the fixed handle 21 is fixed with a side clamping plate 25, which is symmetrically installed along the center of the axis of the fixed handle 21.

[0040] The opposite surfaces of the side plate 25 are tightly fitted to the outer side of the elastic ring 23. The bottom of the fixed handle 21 is fixedly installed with a pressure plate 24, and the outer side of the pressure plate 24 is slidably adapted to the plate groove of the fixed cover 1. The bottom of the pressure plate 24 is provided with a pressure groove. Both sides of the pressure groove of the pressure plate 24 are inclined surfaces that slope outward from top to bottom. The bottom of the pressure plate 24 near the pusher mechanism 3 is an inclined surface that slopes inward from top to bottom. The downward movement of the pressure plate 24 drives the bending plate 26, so that the bending plate 26 bends inward at both ends of the nail under the obstruction of the stop bar 6, and then contacts the conical block 8. During the gradual downward movement, the stop bar 6 stops obstructing the nail, allowing the nail to be smoothly driven into the wound. The bending plate 26 is fixedly installed on the side of the pressure plate 24 near the end cover 4. The bottom of the bending plate 26 is provided with an arc-shaped protrusion, and the bending plate 26 is located directly above the conical block 8.

[0041] Example 3, based on Examples 1 and 2, please refer to... Figures 8 to 9 As shown, the push-nail mechanism 3 includes a hollow groove plate 31. The bottom of the hollow groove plate 31 is fixedly connected to the center of the top of the base plate 5. A groove is opened at the center of the top of the hollow groove plate 31. In the push-nail mechanism 3, when the tack is inserted, the tack assembly is inserted into the top of the hollow groove plate 31. Then, the push-nail block 33 is inserted into the top of the hollow groove plate 31, and the sliding hole block 35 is inserted into the groove of the hollow groove plate 31. By holding the inner locking block 32, the push-nail block 33 is pushed into the interior of the fixed cover 1 through the fixed connection between the fixing block 38 and the inner sliding rod 37, and the tack assembly is pushed so that the tack near the end cover 4 is pressed against the nail stop plate 7. The sliding hole block 35 is slidably installed in the groove of the hollow groove plate 31. The push-nail block 33 is fixedly installed on the top of the sliding hole block 35. The nail-holding plate 34 is fixedly installed on the top of the push-nail block 33. The side of the nail-holding plate 34 near the end cover 4 is an inclined surface that slopes inward from top to bottom.

[0042] An inner sliding rod 37 is slidably installed on the inner wall of the sliding block 35. A fixing block 38 is fixedly installed at the end of the inner sliding rod 37 away from the sliding block 35, and an inner locking block 32 is fixedly installed on the outside of the fixing block 38. A second spring 36 is fixedly installed between the inner locking block 32 and the sliding block 35. When the leather nail group is pushed in, after the leather nail group reaches the designated position, the position of the pusher block 33 is restricted. When the user pushes the inner locking block 32, the second spring 36 is compressed until the arc-shaped protrusion of the inner locking block 32 and the protrusion of the fixing cover 1 are mutually locked. The second spring 36 is located on the outside of the inner sliding rod 37. Arc-shaped protrusions are provided on both sides of the inner locking block 32. Protrusions are provided on both sides of the inner wall of the fixing cover 1. The inner locking block 32 is locked with the protrusion of the fixing cover 1 through the arc-shaped protrusion.

[0043] In use, place the suture nails required for suturing the wound between the fixing cover 1 and the base plate 5, and press the suture nails with the push nail mechanism 3 so that the suture nails near the end cover 4 are in close contact with the plane of the nail stop plate 7. Then, by holding the nail pressing mechanism 2, the nail pressing mechanism 2 cooperates with the stop bar 6 to drive the U-shaped nails into the skin on both sides of the wound, and suture and fix the wound.

[0044] When inserting the staples, the pressure of the staple pressing mechanism 2 causes the staple closest to the staple stop plate 7 to be pressed down and inserted into the skin on both sides of the wound. Simultaneously, during the downward movement of the staples, the stop bar 6 obstructs the staples, causing the staple heads on both sides to bend inwards and obliquely insert into the skin as they are inserted. Before insertion, the screw 12 can be rotated according to the skin suture depth. Utilizing the threaded connection between the screw 12 and the sliding plate 11, the sliding plate 11 is positioned at the end cover. The slid slides at the groove of 4 and drives the stop bar 6, which is adjusted according to the insertion depth. After the tack is inserted into the skin, the tack pressing mechanism 2 and the conical block 8 work together to drive the stop bar 6 through the conical block 8, compressing the first spring 9. This causes the stop bar 6 to slide on the inner wall of the sliding plate 11, stopping the obstruction of the tack's downward movement. The top of the tack is then driven by the tack pressing mechanism 2 to reach below the stop bar 6, completing the suture. Afterward, the tack pressing mechanism 2 resets, and the stop bar 6 also resets.

[0045] In the pinning mechanism 2, when in use, the fixed handle 21 is held. When the suture is made by inserting the suture, pressure is applied to the top pressure plate 22, which causes the top pressure plate 22 to deform near the fixed handle 21 and compress the elastic ring 23. As the top pressure plate 22 moves down, it drives the pinning plate 24 down, causing the pinning plate 24 to slide down in the groove of the fixed cover 1. The bottom groove of the pinning plate 24 contacts the top of the suture, causing the suture to move down. At the same time, the downward movement of the pinning plate 24 drives the bending plate 26. After the bending plate 26 is blocked by the stop bar 6 at both ends of the suture, it contacts the conical block 8. As it moves down, the stop bar 6 stops blocking the suture, allowing the suture to be smoothly inserted into the wound.

[0046] In the push-nail mechanism 3, when inserting the tack, the tack assembly is locked into the top of the hollow slot plate 31. Then, the push-nail block 33 is inserted into the top of the hollow slot plate 31, and the sliding block 35 is inserted into the groove of the hollow slot plate 31. By holding the inner locking block 32, the push-nail block 33 is pushed into the interior of the fixing cover 1 through the fixed connection between the fixing block 38 and the inner sliding rod 37, and the tack assembly is pushed so that the tack near the end of the end cover 4 is pressed against the nail stop plate 7. At the same time, when the tack assembly is pushed in, the position of the push-nail block 33 is restricted after the tack assembly reaches the designated position. When the user pushes the inner locking block 32, the second spring 36 is compressed until the arc-shaped protrusion of the inner locking block 32 and the protrusion of the fixing cover 1 are locked together.
