Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, and in particular to a surgical needle holder. BACKGROUND

[0002] Surgery requires great skill and experience, especially in restricted suture areas where precision is critical. Rotational movement can help minimize tissue tearing during suturing. By properly rotating the needle as it penetrates the tissue, the applied force is evenly distributed, which reduces the risk of damaging the tissue around the incision site. This technique is critical to minimize trauma and promote better healing. If the needle is not handled properly, tearing can occur during suturing. Optimal rotation technique is critical to prevent secondary or further damage to the target tissue. Ideal rotation significantly reduces the risk of tearing force.

[0003] Ensuring even tension on the suture site after placement also helps in optimal healing. Correct suturing technique, including even tension and precise suture placement, ensures that the wound edges are consistently brought together without exerting excessive pressure on any particular point. This minimizes tissue damage, reduces scarring, and speeds up healing. Even distribution of force on the suture site helps maintain blood flow to the tissue, which is critical for healing, and reduces the likelihood of complications such as infection or reopening of the wound.

[0004] In complex surgical procedures, achieving effective rotation for tissue penetration in narrow and deep surgical sites remains challenging, especially when further incisions are undesirable to minimize patient trauma and extensive wrist movement is impractical. This instrument can avoid the need for extensive wrist movement and minimize the trajectory of the needle, allowing penetration of the target tissue with minimal tearing.

[0005] To address the aforementioned problems and improve the skills of inexperienced surgeons in primary wound closure, a new surgical needle holder is needed, designed to overcome the problems associated with current surgical suturing and wound closure techniques. SUMMARY

[0025] Reference Figure 1 and Figure 2 The surgical needle holder 10 includes a front portion 100 and a rear portion 200. The front portion 100 is capable of rotating and moving separately from the rear portion 200. Specifically, the front portion 100 includes a beak 110, a rotating rod 120, and a main rotating gear 130. The beak 110 is configured to hold a surgical needle. The rotating rod 120 is connected to the beak 110. The main rotating gear 130 is coaxially and fixedly connected to the rotating rod 120. The rear portion 200 includes a handle 210, a finger platform 220, and an auxiliary gear 230. The handle 210 is detachably connected to the beak 110. The finger platform 220 is slidably connected to the handle 210. The finger platform 220 is meshed with the auxiliary gear 230, and the auxiliary gear 230 is meshed with the main rotating gear 130.

[0026] A right-handed user can place the middle finger on the finger platform 220 to perform a sliding movement. The finger platform 220 can activate the main rotating gear 130 of the front part 100 to perform a rotating movement. When the finger platform 220 is pushed toward the beak 110, the finger platform 220 drives the auxiliary gear 230 to rotate, and the auxiliary gear 230 drives the main rotating gear 130 to rotate. The main rotating gear 130 drives the rotating rod 120 to rotate, and the rotating rod 120 drives the beak 110 to rotate. Figure 3 and Figure 4 The surgical needle holder 10 has a flexible and rotating beak 110. When entering a narrow space, the beak 110 can be disengaged to perform clockwise and counterclockwise rotation, allowing the needle to be rotated effortlessly. This surgical needle holder 10 can eliminate the need for wrist rotation and reduce hand muscle fatigue.

[0027] Reference Figure 5 and Figure 6, the surgical needle holder 10 can be opened and closed to clamp the surgical needle. In one embodiment, the beak 110 is provided with a groove 112 to hold the suture material on the surgical needle. In one embodiment, the center of the groove is sandblasted to provide friction to hold the suture material of the surgical needle.

[0028] Reference Figure 7 and Figure 8 In some embodiments, the front portion 100 further includes a multifunctional holder 140. The beak 110 includes a first beak portion 114 and a second beak portion 116. The first beak portion 114 and the second beak portion 116 are connected to the multifunctional holder 140 and are capable of rotating with the multifunctional holder 140. The rotating rod 120 is fixedly connected to the multifunctional holder 140 and is capable of driving the multifunctional holder 140 to rotate. In one embodiment, the rotating rod 120 will be welded after being connected to the circular opening 142 of the multifunctional holder 140. When the finger platform 220 faces upward, the first beak portion 114 moves from right to left, and the second beak portion 116 moves from left to right. In one embodiment, the front portion 100 may further include a nut 150 to hold the multifunctional holder 140, the first beak portion 114, and the second beak portion 116 in place.

[0029] The multifunctional holder 140 can provide multiple functions. First, the multifunctional holder 140 provides an axis of rotation for the beak 110 during opening and closing of the surgical needle holder 10. Second, because the rotation rod 120 is fixed to the multifunctional holder 140, when the finger platform 220 is pushed or pulled, the multifunctional holder 140 drives the rotation of the entire front portion 100.

[0030] Reference Figure 1 、 Figure 5 and Figure 6 In one embodiment, the handle 210 can include a first handle portion 212 and a second handle portion 214. The first handle portion 212 and the second handle portion 214 are capable of relative movement during opening and closing of the surgical needle holder 10.

[0031] Reference Figure 9In one embodiment, the handle 210 can include a ratchet 216 to maintain the posture of the rear portion 200, and the handle 210 can also include two finger loops 218 for a user to grip the surgical needle holder 10. In one embodiment, the rear portion 200 can also include a track 240 and a track support 250. The track 240 is for the sliding of the finger platform 220. The track support 250 is for holding both the track 240 and the auxiliary gear 230 in place. The finger platform 220 is mounted on the track 240 and is able to slide along the track 240. The track 240 is mounted on the track support 250. The track support 250 is telescopic. The two end portions of the track support 250 are connected to the first handle portion 212 and the second handle portion 214, respectively.

[0032] Furthermore, in some embodiments, the track support 250 is curved. The track support 250 is designed to be curved instead of straight to achieve a trajectory from the center of rotation located at the multi-functional holder 140. The opening trajectory of the first handle portion 212 and the second handle portion 214 is curved, so the track support 250 is also curved to better align with the trajectory. In one embodiment, referring to FIGS. 1-3 and 5-7 simultaneously, Figure 10 The track support 250 includes an inner rod 251 and an outer tube 252. The inner rod 251 is slidably positioned within the outer tube 252. The inner rod 251 is able to extend from and retract into the outer tube 252 during the opening and closing of the surgical needle holder 10.

[0033] Referring to Figure 10A In some embodiments, the track support 250 can also include an engagement portion stopper 258 and an engagement portion blocker 259. The engagement portion stopper 258 is connected to the end of the inner rod 251 and extends outward, while the engagement portion blocker 259 is connected to the end of the outer tube 252 and extends inward. The engagement portion blocker 259 on the outer tube 252 can prevent the engagement portion stopper 258 from disengaging from the outer tube 252, thereby ensuring that the inner rod 251 and the outer tube 252 remain securely connected and do not separate. In one embodiment, the engagement portion stopper 258 can be a hemispherical structure, and the engagement portion blocker 259 can be a ring-shaped structure. The outer diameter of the hemispherical structure is larger than the inner diameter of the ring-shaped structure.

[0034] In some embodiments, the track support 250 includes a first track support 253, a second track support 254, and a third track support 255, with the second track support 254 positioned between the first track support 253 and the third track support 255. The first track support 253 includes a first connecting tube 256. The rotation rod 120 passes through the first connecting tube 256. The second track support 254 includes a second connecting tube 257. The rotation rod 120 passes through the second connecting tube 257, and the auxiliary gear 230 is connected to the second connecting tube 257.

[0035] The male portion 340 of the front and rear joint 300 and the inner rod 251 of the track support 250 are made of a shape memory alloy such as Nitinol, which is composed of nickel and titanium, which can be slightly bent and can restore its shape after the pressure is released. During compression, the joint limit stop 258 of the track support 250 will rotate inside the outer tube 252, the spherical design of the end of the joint limit stop 258 not only can act as a stop to disengage the joint stopper 259, but also allows a small range of rotation to release the ratchet mechanism.

[0036] Referring to Figure 10B and Figure 10C In one embodiment, the auxiliary gear 230 is connected to the second connecting tube 257 through a connector 230A. The connector 230A is provided with a ring groove 230B. The connector 230A is attached to the axis of the auxiliary gear 230. The auxiliary gear 230 is inserted into the ring groove 230B.

[0037] Referring to Figure 7 and Figure 10 In one embodiment, the rotating rod 120 includes a first movement stop 121, a second movement stop 122, and a third movement stop 123, the first movement stop 121 abutting the first connecting tube 256 and positioned on the side closer to the second track support 254; the second movement stop 122 and the third movement stop 123 abutting the second connecting tube 257 and positioned on both sides of the second connecting tube 257, respectively. The movement stops limit the front and rear movement of the front portion 100, thereby preventing the front portion 100 from disengaging.

[0038] Referring to Figure 7A and Figure 7B In one embodiment, the first movement stop 121 can be a ring with an opening 121A. The first movement stop 121 can be installed on the body of the rotating rod 120 through the opening 121A. Then, the first movement stop 121 can be welded to be fixed on the rotating rod 120. The second movement stop 122 and the third movement stop 123 can be the same as the first movement stop 121.

[0039] Referring to Figure 2 , Figure 11 and Figure 11AIn one embodiment, the finger platform 220 includes a finger holder 221, a gear-shaped side edge 222, a transverse track guide 223, and a stopper 224. The finger holder 221 is configured to accommodate the middle finger of a right-handed user. The gear-shaped side edge 222 is located on the side edge of the finger holder 221 and meshes with an auxiliary gear 230. The gear-shaped side edge 222 pushes the auxiliary gear 230, which in turn rotates the main rotating gear 130. The rotation of the main rotating gear 130 drives the entire front portion 100. The transverse track guide 223 is located on the surface of the finger holder 221 to limit the horizontal movement of the track 240, thereby preventing horizontal disengagement. The stopper 224 is located on the surface of the finger holder 221 to limit the vertical movement of the finger holder 221, thereby preventing vertical disengagement. Another function of the stopper 224 is to prevent the user from pushing the finger platform 220 too far forward or pulling it too far backward. This surface can be the bottom surface. In other embodiments, details of the surgical needle holder 10 may be modified to further increase the range of rotation.

[0040] Reference Figure 1 and Figure 12 In one embodiment, the surgical needle holder 10 further includes a front-to-back joint 300 located between the beak 110 and the handle 210 and configured to detachably connect the beak 110 and the handle 210. During the rotational movement of the front portion 100 at the front-to-back joint 300, the front portion 100 and the rear portion 200 are disengaged.

[0041] The front-to-back joint 300 includes a female portion 320 and a male portion 340. In one embodiment, the female portion 320 is disposed in the rear portion 200 and connected to the end of the handle 210. The male portion 340 is disposed in the front portion 100 and connected to the end of the beak 110. In another embodiment, the positions of the female portion 320 and the male portion 340 can be interchanged. In one embodiment, the surgical needle holder 10 can include two front-to-back joints 300. One front-to-back joint 300 connects the first beak portion 114 and the first handle portion 212. The other front-to-back joint 300 connects the second beak portion 116 and the second handle portion 214.

[0042] Reference Figure 3 、 Figure 4 and Figure 13The female portion 320 has two arms 322 with a recess 324 formed therebetween to accommodate the male portion 340. When the male portion 340 is positioned in the recess 324, the beak 110 and the handle 210 are connected, thereby allowing the surgical needle holder 10 to be opened and closed. When the front portion 100 is rotated relative to the rear portion 200, the male portion 340 is disengaged from the recess 324. When the male portion 340 is inserted between the two arms 322 of the female portion 320, the male portion 340 can be prevented from being horizontally disengaged during the opening and closing of the surgical needle holder 10.

[0043] The female portion 320 can hold the male portion 340 in place during two rotational movements. One rotational movement is the rotation of the needle holder during opening and closing, and the other rotational movement is the rotation of the entire front portion 100. Specifically, the notch 324 holds the male portion 340 in place and prevents vertical disengagement of the front portion 100 when the front and rear joint retainers 360 are inserted into the recesses 326 of the female portion 320. The two arms 322 prevent horizontal disengagement. The two arms 322 can hold the male portion 340 in place during both rotational movements. The male portion 340 can mate with the female portion 320. The connection between the male portion 340 and the female portion 320 provides support for the function of the front portion 100 during both rotational movements.

[0044] Reference Figure 13 , in one embodiment, the front and rear joint 300 further includes a front and rear joint retainer 360, a front and rear joint retainer ejector 380, and a cover 390. The end of the male portion 340 is provided with a hole 342. The front and rear joint retainer ejector 380 is located in the hole 342. The front and rear joint retainer 360 is positioned at the end of the front and rear joint retainer ejector 380. In one embodiment, the front and rear joint retainer 360 can be a spherical structure. The cover 390 is connected to the male portion 340 and confines a portion of the front and rear joint retainer 360 within the hole 342, while another portion of the front and rear joint retainer 360 remains outside the hole 342. Referring to Figure 14 The bottom of the notch 324 is provided with a recess 326 to hold the front and rear joint retainers 360 outside the hole 342. In one embodiment, the front and rear joint retainers 360 can be hemispherical end metals with a protruding circular metal ring in the middle of the front and rear joint retainers 360, which prevents them from falling out of the hole of the male part 340.

[0045] The front and rear joint retainers 360 can hold the male portion 340 in place after being connected to the recess 326 of the female portion 320. The front and rear joint retainer ejectors 380 can push the front and rear joint retainers 360, thereby maintaining the position of the front and rear joint retainers 360 in the recess 326. The cover 390 can prevent the front and rear joint retainers 360 from falling out. In one embodiment, the front and rear joint retainer ejectors 380 can be fluorocarbon elastomer. Fluorocarbon elastomers exhibit excellent heat and chemical resistance, as well as significant long-term compression resistance, making them very effective as ejector and sealing materials. Their resistant properties ensure that they can be thoroughly sterilized, thereby maintaining integrity in demanding applications. Reference Figure 13A In another embodiment, the front and rear joint retainer ejectors 380 may be springs. In one embodiment, the springs may be made of metal. The front and rear joints may also be various types of knuckles or recesses (such as magnetic) or other shapes with similar functions to the current embodiment.

[0046] Reference Figure 15 、 Figure 15A 、 Figure 16 and Figure 16A The surgical needle holder 10 further includes a beak holder 400 positioned between the multifunctional holder 140 and the beak 110. The design of the beak holder 400 can be similar to the female portion 320 and the male portion 340 of the front and rear joints 300. In some embodiments, the beak holder 400 includes a front portion holder 420, a front portion holder ejector 440, and a beak stopper 460.

[0047] Reference Figure 16AThe multifunctional retainer 140 has a hollow portion 144. A front portion retainer ejector 440 is located within the hollow portion 144. The front portion retainer 420 is positioned at the end of the front portion retainer ejector 440. In one embodiment, the front portion retainer 420 may be a spherical structure. A beak stopper 460 is connected to the multifunctional retainer 140 and confines a portion of the front portion retainer 420 within the hollow portion 144, while retaining another portion of the front portion retainer 420 outside the hollow portion 144. In one embodiment, the beak stopper 460 may include a beak stopper body 462 and a beak stopper retainer 464. The beak stopper body 462 is a ring structure with a threaded texture. The beak stopper retainer 464 is located at the edge of the hollow portion 144 and has a threaded texture that matches that of the beak stopper body 462. The beak 110 has a cavity 118 to retain the front portion retainer 420 outside the hollow portion 144. The beak stopper retainer 464 is a threaded texture used to secure the beak stopper body 462 to retain the front portion retainer 420. In one embodiment, the front portion retainer 420 may be a hemispherical end metal with a protruding circular metal ring in the middle of the front portion retainer 420 that prevents it from falling out of the hollow portion 144 of the multi-function retainer 140.

[0048] The number of beak retainers 400, hollow portions 144, and cavities 118 can be multiple. Each beak retainer 400 corresponds to one hollow portion 144 and one cavity 118. The beak retainers 400 are arranged around the multifunctional retainer 140. When the first and second handle portions 212, 214 are disengaged, the beak retainers 400 help hold the first and second beak portions 114, 116 in place. Similar designs are made on both ends of the multifunctional retainer, including the front portion retainers 420, to hold the first and second beak portions 114, 116 in place. The cavity 118 can be a hemispherical hole. The cavity is made in the first and second beak portions 114, 116 to allow for the insertion of the front portion retainer 420 to lock the beak. Alternatively, it can be any type of knuckle, notch (such as a magnetic one), or other design with similar functionality to the current embodiment.

[0049] Operation of the surgical needle holder 10 for a right-handed user may include the following steps: First, insert the thumb and ring finger into the finger ring 218 , rest the index finger on the left side of the surgical needle holder 10 , and rest or hover the middle finger over the finger platform 220 .

[0050] Secondly, once the needle penetrates the target tissue, the beak 110 can be rotated by simply pushing the finger platform 220 forward. If the user wishes the beak 110 to rotate clockwise, they can position the finger platform 220 until the stop 224 almost reaches its limit or reaches its limit, thereby positioning the finger platform 220 until the stop 224 reaches its limit. When the finger platform 220 is pulled back toward the user's palm, the beak 110 will rotate clockwise. When the stop 224 almost reaches its limit or reaches its limit, the female portion 320 and the male portion 340 must be connected. The user can be a clinician.

[0051] Then, the gear-shaped side edge 222 of the finger platform 220 will engage with the auxiliary gear 230 to rotate counterclockwise, which causes the main gear connected to the rotating rod 120 to rotate counterclockwise.

[0052] Once the rotating rod 120 is rotated, the beak 110 begins to rotate counterclockwise, with the maximum rotation limit being 1080 degrees.

[0053] Additionally, the user should ensure that the finger platform 220 is always facing upward.

[0054] If the user opens the surgical needle holder 10 during rotation of the beak 110, where the beak 110 cannot return to its original position (the front and rear joints 300 cannot connect), the user will need to manually restore the position by first compressing the lateral portion of the beak 110 to close the beak 110, after which the user should close the rear portion and thereafter push or pull the finger platform to connect the front portion 100 and the rear portion 200.

[0055] The technical features in the above embodiments may be randomly combined. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described. However, as long as the combination of technical features does not conflict with each other, the combination of technical features is deemed to fall within the scope described in this specification.
