Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a needle holder for surgical procedures. Background Technology

[0002] In surgical procedures, surgical needle holders are typically used to hold suture needles to suture various tissues. They are also sometimes used to assist in tying knots with instruments, thereby ensuring the smooth progress of the surgery.

[0003] A search revealed a Chinese patent with publication number CN217471997U, which describes a general surgical needle holder. The holder includes a first movable rod, a second movable rod, and two clamp arms. Each of the first and second movable rods has a handle at one end and a sliding groove at one end. A clamp arm is slidably connected within each sliding groove. A rotating rod is rotatably connected within one sliding groove, and the rotating rod is threaded to the corresponding clamp arm. The two clamp arms are cross-connected via a rotating shaft. Each clamp arm has a clamp mouth connected to one end. A slider is mounted on the side wall of the first movable rod, and a fixed frame that is slidably fitted onto the outside of the slider is mounted on the side wall of the second movable rod.

[0004] Although the aforementioned patent can effectively hold the suture needle, it still has the following drawbacks in practical applications:

[0005] 1. Lack of jaw angle adjustment function: Since the jaw is directly fixed to the jaw arm and the angle cannot be adjusted, it is difficult to operate flexibly when dealing with certain specific locations (such as inside organs or blood vessels), especially in confined spaces, where the suture needle may have difficulty reaching the required position, affecting the flexibility and accuracy of the operation.

[0006] 2. Lack of suture cutting function: The needle holder mentioned above does not have the ability to cut sutures. After suturing is completed, it is necessary to use suture cutters to cut the sutures, which increases the operation steps and reduces the efficiency of the operation. Utility Model Content

[0007] The purpose of this invention is to provide a surgical needle holder that integrates angle adjustment and suture cutting functions. This needle holder can not only flexibly adjust the angle of the jaws to adapt to the operational needs of the surgical environment, but also directly cut the suture after suturing is completed, thereby improving surgical efficiency and ease of operation.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a surgical needle holder, comprising a clamp body and clamp mouths, the two clamp bodies being cross-connected by a rotating shaft, the two clamp mouths being respectively hinged to the two clamp bodies, the clamp body being provided with a drive component for driving the clamp mouths to rotate and adjust the angle, one clamp mouth having a mounting groove, in which a cutter is slidably mounted, the other clamp mouth having a blade groove matching the cutter, the clamp mouth with the cutter having a push component, the push component being connected to a pull rope two, the clamp mouth with the cutter having a guide tube three connected to the side opposite to its clamping part, the clamp body connected to the clamp mouth with the cutter having a guide tube two connected to the guide tube two, the pull rope two passing through the guide tube three and the guide tube two, pulling the pull rope two to move can drive the push component to push the cutter to cut the suture.

[0009] Preferably, the drive assembly includes a conduit embedded in the clamp body, a groove on the side of the clamp body away from the jaws, a slider slidably disposed in the groove, a lead screw rotatably connected in the groove, the lead screw being threadedly connected to the slider, a pull rod connected to the jaws, a pull rope connected to the pull rod, the pull rope passing through the conduit and connected to the slider, and a torsion spring connected at the hinge between the jaws and the clamp body.

[0010] Preferably, the pushing component includes a gear shaft rotatably connected to a mounting groove in a jaw with a cutter. A disc is connected to the shaft of the gear shaft. A slot is formed on the cutter. A push rod located in the slot is connected to an eccentric position on the disc. A rack is slidably provided on the side of the jaw with the cutter opposite to its clamping part. The rack on the rack meshes with the gear on the gear shaft. A return spring is connected between the rack and the jaw with the cutter. A second pull rope is connected to the rack.

[0011] Preferably, the second pull rope is connected to a pull ring for inserting a finger.

[0012] Preferably, the clamping portion of the jaws has spaced toothed grooves.

[0013] Preferably, the ring handle of the pliers is provided with an anti-slip rubber ring to increase friction with the fingers.

[0014] The beneficial effects of this invention are as follows: By hinged the jaws to the jaw body, the driving component can rotate the jaws to adjust the angle. The adjustable jaw angle improves flexibility, allowing for flexible operation when dealing with specific locations, especially in confined spaces, enabling the suture needle to accurately reach the required position, thus improving the flexibility and accuracy during surgery. Pulling the pull ring moves the pull cord, which in turn pushes the cutting component to push the cutter out of the mounting slot on the jaws to cut the suture, eliminating the need to use suture cutters, reducing operational steps and improving surgical efficiency. Thus, this invention integrates angle adjustment and suture cutting functions, not only allowing for flexible adjustment of the jaw angle to adapt to operational needs in the surgical environment, but also enabling direct cutting of the suture after suturing, improving surgical efficiency and ease of operation.

Detailed Implementation

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Please see Figures 1-8A surgical needle holder includes a clamp body 1, clamp jaws 2, an anti-slip rubber ring 3, a drive assembly, a pull ring 10, a second pull rope 11, a second guide tube 12, a third guide tube 13, a cutter 18, and a push assembly. Two clamp bodies 1 are cross-connected by a pivot, and two clamp jaws 2 are respectively hinged to the rear sides of the two clamp bodies 1. The clamping parts of the clamp jaws 2 have spaced toothed grooves, which increase the contact area between the clamp jaws 2 and the suture needle. The toothed structure can better embed into the suture needle surface, thereby significantly increasing friction and providing a better mechanical engagement effect, thus clamping the suture needle more firmly. An anti-slip rubber ring 3 is provided inside the annular handle of the clamp body 1. The outer wall of the anti-slip rubber ring 3 has an annular groove, through which the anti-slip rubber ring 3 engages with the annular handle of the clamp body 1. To facilitate the replacement of the anti-slip rubber ring 3, the anti-slip rubber ring 3 increases the friction between the fingers and the ring handle on the clamp body 1, thereby achieving an anti-slip effect and providing cushioning protection for the fingers, reducing the pressure on the fingers when holding the clamp body 1 for a long time, thus improving the comfort of holding. The clamp body 1 is equipped with a drive assembly that drives the jaws 2 to rotate and adjust the angle. The drive assembly includes a wire tube 7 embedded in the clamp body 1. A sliding groove is opened on the front side of the clamp body 1, and a slider 5 is slidably installed in the groove. A lead screw 4 is rotatably connected in the groove. The lead screw 4 is threadedly connected to the slider 5. A knob is connected to the lead screw 4, and the slider 5 is moved by rotating the lead screw 4. A pull rod 9 is connected to the jaws 2, and a pull rope 6 is connected to the pull rod 9. The pull rope 6 passes through the wire tube 7. 7 is connected to the slider 5. A torsion spring 8 is connected to the hinge between the jaw 2 and the jaw body 1. One jaw 2 has a mounting groove, in which a cutter 18 is slidably mounted. The other jaw 2 has a blade groove that matches the cutter 18. The jaw 2 with the cutter 18 has a pushing assembly. The pushing assembly includes a gear shaft 16 rotatably connected to the mounting groove of the jaw 2 with the cutter 18. A disc 17 is connected to the shaft of the gear shaft 16. A slot 19 is opened on the cutter 18. A push rod 20 located in the inner groove 1 of the slot 9 is connected to the eccentric position of the disc 17. A rack frame 14 is slidably mounted on the side of the jaw 2 with the cutter 18 away from its clamping part. The rack on the rack frame 14 meshes with the gear on the gear shaft 16. The rack frame 14 and the cutter 18 are connected to the gear 18. A return spring 15 is connected between the jaws 2 of the cutter 18. A guide rod is connected to the side of the jaws 2 with the cutter 18 that is opposite to its clamping part. The guide rod slides through the rack frame 14. The return spring 15 is sleeved on the guide rod and supported by the guide rod to prevent the return spring 15 from bending when it deforms. A pull rope 2 11 is connected to the front of the rack frame 14. A wire tube 3 13 is connected to the side of the jaws 2 with the cutter 18 that is opposite to its clamping part. The wire tube 3 13 is located in front of the rack frame 14. A wire tube 2 12 is connected to the jaw body 1 connected to the jaws 2 with the cutter 18. The front end of the pull rope 2 11 passes through the wire tube 3 13 and the wire tube 2 12. A pull ring 10 is connected to the front end of the pull rope 2 11. The pull ring 10 allows fingers to easily pull the pull rope 2 11.

[0026] Place your thumb and forefinger into the ring handles of the two clamp bodies 1 respectively. Apply pressure with both fingers to close the clamp bodies 1, thereby closing the two jaws 2 to hold the suture needle for surgery. When adjusting the angle of the jaws 2, rotate the lead screw 4 to move the slider 5 forward. The forward movement of the slider 5 pulls the pull rod 9 upward via the pull rope 6, thus rotating the jaws 2 upward to adjust to the appropriate angle (see [reference]). Figure 2 The torsion spring 8 is compressed accordingly. The adjustable angle of the jaw 2 improves flexibility, allowing for flexible operation when dealing with specific locations (such as inside organs or blood vessels 21), especially in confined spaces, enabling the suture needle to reach the desired position precisely, improving the flexibility and accuracy of the surgical procedure. Reversing the screw 4 causes the slider 5 to move backward to loosen the pull rope 6. Under the reset action of the torsion spring 8, the jaw 2 drives the pull rod 9 to rotate downward, tightening the pull rope 6. When it is necessary to cut the suture, insert the middle finger into the pull ring 10, and pull the pull rope 11 forward through the pull ring 10, thereby pulling the rack frame 14 forward to compress the reset spring 15. The forward movement of the rack frame 14 pushes the gear shaft 16 to rotate the disc 17. The rotation of the disc 17 pushes the cutter 18 out of the mounting slot on the jaw 2 through the push rod 20 to cut the suture. There is no need to use suture cutters to cut the suture, reducing the number of operation steps and improving surgical efficiency. Loosening the pull ring 10, the reset spring 15 pushes the rack frame 14 backward to tighten the pull rope 11. The backward movement of the rack frame 14 pushes the gear shaft 16 to rotate the disc 17 in reverse. The reverse rotation of the disc 17 pushes the cutter 18 back into the mounting slot of the jaw 2 via the push rod 20. Thus, this needle holder integrates angle adjustment and suture cutting functions. It can not only flexibly adjust the angle of the jaw 2 to adapt to the operational needs of the surgical environment, but also directly cut the suture after suturing, improving surgical efficiency and ease of operation.

It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
