Serial vascular clip applier

Abstract

This application discloses a continuous-fire vascular clamp applicator, including a pressure rod, a main rod, and a clamping body with a continuous-fire cartridge. By pushing the handle with the hand, the first spring is compressed, reducing the distance between the handle and the main rod. This causes the handle to deflect the inclined rod within a movable groove, which in turn causes the pressure head to move downward, allowing the pressure column to insert into the pressure hole at one end of the groove. Specifically, by squeezing the handle, the pressure head drives the pressure column into the pressure hole, pushing the upper pressure head out of the pressure hole so that the upper and lower clamps of the vascular clamp come into contact and engage, thus clamping the vascular clamp onto the blood vessel. Releasing the handle pushes the first spring away from the main rod, causing the pressure head and the pressure column to be pulled out of the pressure hole. The pusher then pushes the upper clamp of the next vascular clamp in the groove into the pressure hole. This allows the vascular clamp to clamp the blood vessel without the need to reinstall the vascular clamp, enabling continuous use of vascular clamps to clamp and stop bleeding, reducing the time spent on vascular clamping operations, thereby reducing bleeding and surgical risks.

Description

Technical Field

[0001] This utility model belongs to the field of vascular clip technology, specifically relating to a continuous-fire vascular clip applicator. Background Technology

[0002] Many surgical procedures, such as organ transplantation and tumor removal, require temporary occlusion of blood vessels or other fluid or tissue ducts and structures to prevent bleeding and to allow for clearer visualization of the surgical area.

[0003] Vascular clamps are typically applied manually by using forceps to clamp a vessel, then using the clamp to hold the vessel in place. Afterward, the forceps need to be reloaded with a new clamp before clamping other vessels. This process prolongs the procedure, increases the time spent clamping vessels, leads to increased bleeding, and raises surgical risks and patient discomfort. Utility Model Content

[0004] This application proposes a continuous-fire vascular clamping device that carries multiple vascular clamps at once, enabling continuous clamping and hemostasis of blood vessels, reducing the time required for vascular clamping operations, thereby reducing bleeding and surgical risks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A continuous-fire vascular clip applicator includes a pressure rod, a main rod, and a clip body with a continuous-fire cartridge. One end of the pressure rod has a pressure head connected to a pressure column at its lower part. The other end of the pressure rod has a grip. The rod body has a diagonal bar that passes through a movable groove on the main rod. The diagonal bar is rotatably connected to the inner wall of the movable groove via a pivot. The clip body with a continuous-fire cartridge is mounted on the lower part of one end of the main rod. The other end of the main rod is located on the upper part of the grip and is connected to the grip via a first spring. The clip body with a continuous-fire cartridge has a receiving groove in which a clip is placed. A vascular clamp is provided, comprising an upper clamping rod and a lower clamping rod. One end of the upper clamping rod is connected to an upper clamping head, and one end of the lower clamping rod is connected to a lower clamping head. The upper clamping head and the lower clamping head can be pressed and fastened together. The other ends of the upper clamping rod and the other ends of the lower clamping rod are connected by an elastic bending part. A sliding groove is provided on the upper part of the receiving groove, and the upper clamping head of the vascular clamp is placed in the sliding groove. The lower clamping head of the vascular clamp abuts against the bottom surface of the receiving groove. A push block is provided in the sliding groove, and the push block is connected to a push rod assembly. A pressure hole is provided at one end of the sliding groove, and the pressure hole is located below the pressure column.

[0006] In one embodiment of this application, the lower end face of the upper clamp of the vascular clamp is connected to two arc-shaped rods, a gap is provided between the two arc-shaped rods, the bottom end of the arc-shaped rod is provided with a beveled protrusion, the upper end face of the lower clamp is provided with a tapered hole, and the bottom end face of the lower clamp is provided with a concave hole.

[0007] In one embodiment of this application, finger sleeves are provided on the upper end face of the main rod and the lower end face of the grip.

[0008] In one embodiment of this application, a plurality of first springs are provided between the main rod and the grip, and the first springs are detachably connected to the upper end face of the grip.

[0009] In one embodiment of this application, a connecting block is provided at the bottom end of the main rod, and an insertion rod is provided on the end face of the connecting block. The insertion rod is used to connect with the insertion hole at the tail end of the clip body's continuous firing magazine.

[0010] In one embodiment of this application, limiting sleeves are connected to both sides of the main rod.

[0011] In one embodiment of this application, a slit is provided at the connection between the upper clamping rod and the upper clamping head.

[0012] In summary, the technical solution proposed in this application includes the following beneficial technical effects: This application reduces the distance between the grip and the main rod by squeezing the first spring through a hand-held pusher, causing the grip to drive the inclined rod to deflect within the movable groove, thereby causing the pressure head to move downwards and the pressure column to insert into the pressure hole at one end of the slide groove. That is, by squeezing the grip, the pressure head drives the pressure column to insert into the pressure hole, pushing the upper pressure head out of the pressure hole so that the upper and lower clamps of the vascular clamp come into contact and engage, thus clamping the vascular clamp onto the blood vessel. Releasing the grip pushes the first spring away from the main rod, causing the pressure head to be pulled out of the pressure hole. The pusher then pushes the upper clamp of the next vascular clamp in the slide groove into the pressure hole. This allows the vascular clamp to clamp the blood vessel without the need to reinstall the vascular clamp, enabling continuous use of vascular clamps to clamp and stop bleeding, reducing the time of vascular clamping operations, thereby reducing bleeding and surgical risks.

[0019] This embodiment provides a rapid-fire vascular clip applicator, see reference. Figures 1-8 As shown, the device includes a pressure rod 1, a main rod 2, and a clip-on trigger box 3. One end of the pressure rod 1 has a pressure head 11, with a pressure column 111 connected to its lower part. The other end of the pressure rod 1 has a grip bar 12. The rod body of the pressure rod 1 has a diagonal bar 13, which passes through a movable groove 21 on the main rod 2. The diagonal bar 13 is rotatably connected to the inner wall of the movable groove 21 via a pivot. The clip-on trigger box 3 is installed at the lower part of one end of the main rod 2. The other end of the main rod 2 is located above the grip bar 12 and is connected to the grip bar 12 via a first spring 121. The clip-on trigger box 3 has a receiving groove 31, in which a vascular clamp 4 is placed. The vascular clamp 4 includes an upper clamping rod 41. The upper clamp 41 is connected to an upper clamp head 411 at one end, and the lower clamp 42 is connected to a lower clamp head 421 at one end. The upper clamp head 411 can be squeezed and fastened with the lower clamp head 421. The other end of the upper clamp 41 and the other end of the lower clamp 42 are connected by an elastic bending part 5. A sliding groove 311 is provided on the upper part of the receiving groove 31. The upper clamp head 411 of the vascular clamp 4 is placed in the sliding groove 311, and the lower clamp head 421 of the vascular clamp 4 abuts against the bottom surface of the receiving groove 31. A push block 3111 is provided in the sliding groove 311. The push block 3111 is connected to the push rod assembly 3112. A pressure hole 3113 is provided at one end of the sliding groove 311. The pressure hole 3113 is located below the pressure column 111.

[0020] In the above embodiment, the clip-body trigger box 3 is connected to the lower part of one end of the main rod 2, and multiple vascular clips 4 are arranged in the receiving groove 31 of the clip-body trigger box 3. The upper clamp 411 of the vascular clip 4 is placed in the slide groove 311 of the receiving groove 311, and the lower clamp 421 of the vascular clip 4 abuts against the bottom surface of the receiving groove 31. A push block 3111 is provided in the slide groove 311, and the push block 3111 is connected to the push rod assembly 3112. The push rod assembly 3112 is used to push the push block 3111 and push the upper clamp 411 of the vascular clip 4 in the slide groove 311 into the pressure hole 3113 at one end of the slide groove 311. The pressure hole 3113 is located below the pressure post 111, such as Figure 1 As shown, the grip 12 of the pressure rod 1 is connected to the tail end of the main rod 2 via a first spring 121. In the initial state, there is a certain distance between the grip 12 and the tail end of the main rod 2, causing the pressure head 11 to drive the pressure column 111 above the pressure hole 3113. When the hand pushes the grip 12 to squeeze the first spring 121, the distance between the grip 12 and the main rod 2 is reduced, causing the grip 12 to drive the inclined rod 13 to deflect within the movable groove 21, thereby causing the pressure head 11 to move downwards, making... The pressure column 111 is inserted into the pressure hole 3113 at one end of the slide groove 311. Multiple upper clamp heads 411 of the vascular clamps 4 are arranged inside the slide groove 311. A push block 3111 is provided inside the slide groove 311, and the push block 3111 is connected to the push rod assembly 3112. The push rod assembly 3112 is used to push the push block 3111, thereby pushing the upper clamp heads 411 of the vascular clamps 4 inside the slide groove 311 towards the pressure hole 3113 along the setting direction of the slide groove 311. When using the vascular clamps 4, such as... Figure 4 , Figure 5 and Figure 6 As shown, the end of the blood vessel to be clamped is placed between the upper clamping rod 41 and the lower clamping rod 42 of the vascular clamp 4. Squeezing the grip rod 12 causes the pressure head 11 to drive the pressure column 111 into the pressure hole 3113. The upper pressure head 11 in the pressure hole 3113 is pushed out of the pressure hole 3113, so that the upper clamping head 411 of the vascular clamp 4 contacts and engages with the lower clamping head 421, so that the vascular clamp 4 clamps the blood vessel. Releasing the grip rod 12 causes the first spring 121 to push the grip rod 12 away from the main rod 2, so that the pressure head 11 and the moving pressure column 111 are pulled out of the pressure hole 3113. The push block 3111 then pushes the upper clamping head 411 of the next vascular clamp 4 in the slide groove 311 into the pressure hole 3113. This allows the vascular clamp 4 to clamp the blood vessel without the need to reinstall the vascular clamp 4. It can realize the continuous use of the vascular clamp 4 to clamp the blood vessel for hemostasis, reduce the time of vascular clamping operation, thereby reducing the amount of bleeding and reducing the surgical risk.

[0021] In one embodiment of this application, see reference Figure 6 , Figure 7As shown, the lower end face of the upper clamp 411 of the vascular clamp 4 is connected to two arc-shaped rods 4111, and a gap is provided between the two arc-shaped rods 4111. The bottom end of the arc-shaped rods 4111 is provided with a beveled protrusion. The upper end face of the lower clamp 421 is provided with a conical hole 4211, and the bottom end face of the lower clamp 421 is provided with a concave hole 4212.

[0022] In the above embodiment, when the upper clamp 411 is pressed into contact with the lower clamp 421, the two arc-shaped rods 4111 at the bottom end of the upper clamp 411 slide into the conical hole 4211 along the transition slope of the conical hole 4211. During the process of sliding into the conical hole 4211, the two arc-shaped rods 4111 made of elastic material are elastically bent toward the gap between the two arc-shaped rods 4111, so that the arc-shaped rods 4111 and the slope protrusion at the bottom end of the arc-shaped rods 4111 are inserted into the conical hole 4211. After the two arc-shaped rods 4111 are inserted into the through hole of hole 4211, they spring back, causing the beveled protrusion at the bottom of the arc-shaped rod 4111 to engage with the edge of the through hole of the conical hole 4211, so as to realize the engagement of the upper clamp 411 and the lower clamp 421. The engagement structure is simple and helps to improve the convenience of the clamp engagement of the blood vessel clamp 4. In addition, the concave hole 4212 provided on the bottom end face of the lower clamp 421 is used to accommodate the beveled protrusion at the bottom of the arc-shaped rod 4111 that passes through the through hole of the conical hole 4211.

[0023] In one embodiment of this application, see [reference] Figure 2 As shown, finger sleeves 6 are provided on the upper end face of the main rod 2 and the lower end face of the grip 12.

[0024] In the above embodiment, during the operation, blood from the blood vessels may spurt out, making the gripping points of the main rod 2 and the grip rod 12 slippery and easy to slip off the hand. The finger sleeve 6 is used to increase the contact gripping points between the hand and the main rod 2 and the grip rod 12, which is beneficial to improve the stability of the clamp applicator in the doctor's grip during the operation.

[0025] In one embodiment of this application, see reference Figure 1 As shown, a plurality of first springs 121 are provided between the main rod 2 and the grip 12, and the first springs 121 are detachably connected to the upper end face of the grip 12.

[0026] In the above embodiment, by increasing or decreasing the number of first springs 121 between the main rod 2 and the grip rod 12, the gripping force required for the main rod 2 and the grip rod 12 can be adjusted. More springs require more gripping force, and fewer springs require less gripping force. By increasing or decreasing the number of springs, the feel can be adjusted to suit doctors with different gripping forces, which is beneficial to improving the adaptability of the clamp applicator.

[0027] In one embodiment of this application, see reference Figure 8As shown, a connecting block 22 is provided at the bottom end of the main rod 2, and an insertion rod 221 is provided on the end face of the connecting block 22. The insertion rod 221 is used to be inserted into the insertion hole at the tail end of the clip-on cartridge 3.

[0028] In the above embodiment, the clamping body continuous firing box 3 is connected to the main rod 2 via the insertion rod 221 on the connecting block 22 at the bottom of the main rod 2, which facilitates the disassembly and replacement of the clamping body continuous firing box 3 and helps to improve the convenience and flexibility of the clamping device during use.

[0029] In one embodiment of this application, see reference Figure 1 As shown, limit sleeves 23 are connected to both sides of the main rod 2.

[0030] In the above embodiment, the limiting sleeve 23 is used to limit the distance between the main rod 2 and the grip 12 in the initial state, so as to avoid the main rod 2 and the grip 12 being too far apart, which would make it inconvenient to hold and operate.

[0031] In one embodiment of this application, see reference Figure 7 As shown, a scissor 412 is provided at the connection between the upper clamping rod 41 and the upper clamping head 411.

[0032] In the above embodiment, during the removal of the vascular clamp 4, the upper clamp 411 and the upper clamp rod 41 can be separated by cutting the connection between the upper clamp 411 and the upper clamp rod 41 at the inlet with scissors, and the vascular clamp 4 can be removed from the vascular clamping point. The width of the connection at the cutting point 412 is smaller than the width of the upper clamp rod 41, which makes it easier to cut with scissors and improves the convenience of removing the vascular clamp 4.

[0033] In actual use of this application: by squeezing the grip 12, the pressure head 11 drives the pressure column 111 to insert into the pressure hole 3113, pushing the upper pressure head 11 out of the pressure hole 3113 so that the upper clamp 411 of the vascular clamp 4 contacts and engages with the lower clamp 421, so that the vascular clamp 4 is clamped on the blood vessel. When the grip 12 is released, the first spring 121 pushes the grip 12 away from the main rod 2, so that the pressure head 11 and the moving pressure column 111 are pulled out of the pressure hole 3113. The push rod assembly 3112 pushes the push block 3111 to push the upper clamp 411 of the next vascular clamp 4 in the slide groove 311 into the pressure hole 3113, so that the vascular clamp 4 can clamp the blood vessel without reinstalling the vascular clamp 4. It can realize the continuous use of the vascular clamp 4 to clamp the blood vessel for hemostasis, reducing the time of vascular clamping operation. The push rod assembly 3112 can be a spring push rod or an electric push rod to apply a pushing force to the push block 3111.

[0034] This application aims to disclose the structural features of the device, and the size of the actual device components can be adjusted according to actual needs.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
