Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a medical suture thread pulling and cutting device. Background Art

[0002] Medical sutures refer to special threads used for ligation and hemostasis, suture and tissue suturing during surgical operations or trauma treatment. They are divided into absorbable and non-absorbable threads. Generally, the sutures are stored in a loading device. When needed, they are pulled out from the thread outlet of the loading device. Only as much as needed can be taken out. It is easy to use, but most storage devices are not equipped with cutting mechanisms. When the thread breaks, other cutting tools need to be used, which is more troublesome.

[0003] In the prior art, there is a medical suture pulling and cutting device with publication number CN219331757U, which includes a column connected to a docking seat, and a wire outlet tube is provided inside the docking seat. A cutting mechanism is provided, which can cut according to the required amount, and is easy to use; when the suture is cut, the thread end is located inside the wire passage, and a wire pulling mechanism is provided. It is only necessary to slide the movable column to the left, and then press the movable column to make the two mounting plates move closer to the middle, so that the two clamps clamp the thread end, and then move the movable column to the right, and pull the thread end to the right end exit of the wire passage, which is convenient for taking the thread next time.

[0004] In order to solve the problem of inconvenient access to sutures, the above-mentioned document combines a storage device and a cutting mechanism for surgical sutures. However, in actual use, cutting and clamping the sutures need to be performed in two steps, which is cumbersome to operate. In addition, there is a lack of a protective structure for the cutting mechanism, and the surgical sutures cannot be clamped in time after being cut, which makes it easy for the surgical sutures to curl up and become inconvenient for the next use.

DETAILED DESCRIPTION

[0041] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] For example, see Figures 1 - 19, the present invention provides a technical solution: a medical suture pulling and cutting device, including a suture storage box 1. One end of the suture storage box 1 is movably installed with a movable guard plate 11. A suture loading unit is provided at the end of the suture storage box 1 away from the movable guard plate 11. The suture loading unit includes a loading end cover 2 and a mounting frame 21. A suture traction unit is provided inside the movable guard plate 11. The suture traction unit includes a box body plugging block 3 and a guiding wing block 31. A wire guiding channel is provided inside the guiding wing block 31. An auxiliary disinfection unit is provided at one end of the mounting frame 21. The auxiliary disinfection unit includes a circular limiting cylinder 4; one end of the mounting frame 21 is fixedly connected to the inner side of the loading end cover 2. The two sides of the loading end cover 2 are movably fitted with the inner wall of the suture storage box 1. A winding roller 22 is movably installed inside the mounting frame 21. A lead guiding ring 23 is fixedly installed at the end of the mounting frame 21 away from the loading end cover 2; There are two groups of guiding wing blocks 31, and the two groups of guiding wing blocks 31 are respectively fixedly installed inside the box body plugging block 3, and the guiding wing blocks 31 are mirror-symmetrically distributed about the central axis of the box body plugging block 3. The wire guiding channel is composed of a narrow channel 311 and a wide channel 313. A guiding bevel 312 is provided between the narrow channel 311 and the wide channel 313; Side chutes 10 are opened on both sides of the suture storage box 1, and sliding grooves 310 are opened on the inner wall of the guiding wing block 31. The side chutes 10 and the sliding grooves 310 correspond to each other, and memory sponges are provided inside the side chutes 10 for maintaining the sealing performance of the suture storage box 1;

[0043] When assembling the loading end cover 2 and the suture storage box 1, first wind the surgical suture around the winding roller 22, pull out one end of the surgical thread, pass it through the center of the lead guiding ring 23 and the circular limiting cylinder 4, and pull out the surgical thread a certain distance from the circular limiting cylinder 4. Then, assemble the whole of the loading end cover 2 and the circular limiting cylinder 4 towards the suture storage box 1. Buckling grooves are respectively opened on the inner walls of both sides of the suture storage box 1. Connection pieces are fixedly connected to both sides of the loading end cover 2. Buckling wedges 20 are fixedly installed on the outer surface of the connection pieces. The outer surface of the buckling wedges 20 is adaptively clamped with the inner wall of the buckling grooves. When the loading end cover 2 is pushed into the suture storage box 1, the buckling wedges 20 and the buckling grooves are adapted to each other to realize the quick installation of the loading end cover 2; It should be noted that a fitting groove 3100 is opened at one inner end of the guiding wing block 31, and an inserting block is fixedly added inside the fitting groove 3100. A slot is provided at one inner end of the mounting frame 21. The inner surface of the slot is movably clamped with the outer surface of the inserting block. When the assembly between the loading end cover 2 and the suture storage box 1 is completed, one end of the mounting frame 21 corresponds to the fitting groove 3100 at this time, achieving the effect of secondary stability, ensuring the stable installation of the suture loading unit while avoiding deviation during use, and increasing the overall stability and safety of the device;

[0044] The overall structure integrates the suture loading unit and the suture traction unit with the suture storage box 1 to realize an integrated process for suture retrieval, and cooperates with the setting of the force-bearing traction component to drive the movement of the installation component and the auxiliary clamping component in the wire channel to realize the self-cutting and auxiliary clamping functions of the suture, simplifying the operating steps while avoiding the automatic curling of the suture after cutting; and through the movement of the force-bearing traction component, combined with the extrusion part of the auxiliary disinfection unit, automatic disinfection of the suture outlet is realized, which can not only ensure that the suture is disinfected before use and improve the safety of the operation, but also further simplify the surgical process and improve efficiency.

[0045] Embodiment 2, refer to the attached Figures 1 - 19 On the basis of the first embodiment, in order to realize the use of the suture: the suture traction unit also includes a force traction component, an installation component and an auxiliary clamping component, the force traction component includes a toggle cross bar 32, the two ends of the toggle cross bar 32 are fixedly connected with a force block 321, the center of the toggle cross bar 32 is fixedly connected with a center limit ring 322, one side of the center limit ring 322 is fixedly connected with a connecting rod 323, and the other side of the center limit ring 322 is fixedly installed with a claw plate 3221, and the claw plate 3221 is provided with four groups and a circular array about the central axis of the center limit ring 322; the installation component includes a protective shell 33, the inner side of the protective shell 33 is fixedly connected to one end of the connecting rod 323, the protective shell 33 is a square frame structure, and a traction groove 3300 is opened on the central inner wall of the protective shell 33, and a protective roller 3301 is rotatably installed on the inner side of the traction groove 3300;

[0046] When the surgical suture needs to be taken, the thread end of the suture is pulled outward from one end of the movable guard plate 11. The surgical suture can be cut by pushing the protective shell 33 to different positions of the wire channel, and the cut thread end can be clamped and loosened. In terms of specific operation, the medical staff pinches the force blocks 321 at both ends of the toggle cross bar 32 with two fingers, applies a horizontal thrust to the toggle cross bar 32, and the two sides of the center limit ring 322 at the center position of the toggle cross bar 32 are connected to the protective shell 33 through the connecting rod 323. When the toggle cross bar 32 is moved by force, the protective shell 33 moves synchronously as a whole; it should be noted that when the cross bar 32 is pushed toward one end of the movable guard plate 11, the cutting piece inside the protective shell 33 is in the open state and does not cut the suture; and it is worth noting that the inner side of the traction groove 3300 is installed with protective rollers 3301, which are distributed on both sides of the tangent knife body 332. When the surgical suture is pulled and taken, the protective rollers 3301 can guide the pulled suture and prevent the suture from contacting the tangent knife body 332, so as to avoid the surgical suture from being cut and damaged.

[0047] Embodiment 3, refer to the attached Figures 1 - 19On the basis of the second embodiment, in order to realize the automatic triggering of the cutting member: a cutting knife receiving chamber 330 is respectively provided on both sides of the protective shell 33, and a cutting member is provided on the inner side of the cutting knife receiving chamber 330, and the cutting member includes a tangent knife body 332 and an abutting elastic wire 3321, and the tangent knife body 332 is movably installed on the inner side of the cutting knife receiving chamber 330, one end of the abutting elastic wire 3321 is fixedly connected to the back side of the tangent knife body 332, and the other end of the abutting elastic wire 3321 is fixedly connected to the inner cavity side wall of the cutting knife receiving chamber 330; a moving member is connected to one side of the cutting member, and the moving member includes a lateral guide leg 331 and a lateral guide wheel 3311, the outer surface of the lateral guide leg 331 is slidably connected to the inner walls of both sides of the protective shell 33, and the lateral guide wheel 3311 is installed at one end of the lateral guide leg 331 away from the tangent knife body 332, and the outer surface of the lateral guide wheel 3311 is movably connected to the inner wall of the guide wing block 31;

[0048] When it is necessary to cut the surgical suture, the force block 321 is held and the end of the toggle crossbar 32 close to the loading end cover 2 is pushed to move horizontally. At this time, the lateral guide wheels 3311 connected on both sides of the lateral guide legs 331 enter the narrow channel 311 from the wide channel 313. The guiding bevel 312 here serves as a guide for the movement of the lateral guide wheels 3311. Due to the narrowing of the wire channel, the two groups of lateral guide legs 331 drive the tangent knife body 332 to move relatively inward, and the two groups of tangent knife bodies 332 clamp the suture in the middle, so as to achieve rapid cutting of the surgical suture. The reason why the abutting elastic wire 3321 is connected to the back side of the tangent knife body 332 is that on the one hand, it plays a stabilizing role when the tangent knife body 332 is cut, and on the other hand, it is convenient for the stable resetting of the tangent knife body 332. The cutting knife receiving chamber 330 here can not only play a limiting role in the movement of the tangent knife body 332, but also protect the tangent knife body 332 and the abutting elastic wire 3321.

[0049] Embodiment 4, refer to the attached Figures 1 - 19, on the basis of Embodiment 3, in order to achieve self-clamping before the surgical suture is cut and prevent the problem that the surgical thread curls inward instantaneously during cutting, which affects the next use: The auxiliary clamping assembly includes a connecting member, a guiding member and a linkage clamping member. The connecting member includes a supporting wing plate 34 and a connecting inclined plate 341. The supporting wing plate 34 is fixedly installed on the outer surface of the lateral guiding leg 331. The supporting wing plate 34 is in an "L"-shaped plate structure. The other end of the supporting wing plate 34 is fixedly installed with a connecting inclined plate 341. An inclined slope is arranged on the inner side of the connecting inclined plate 341. The guiding member includes a vertical guiding wheel 342 and a vertical guiding leg 343. The vertical guiding wheel 342 is fixedly connected to the bottom end of the vertical guiding leg 343 through a pin shaft. The outer surface of the vertical guiding wheel 342 is movably connected to the inclined slope of the connecting inclined plate 341. The linkage clamping member includes a connecting tooth bar one 344, a rotating gear 345 and a connecting tooth bar two 346. The bottom end of the connecting tooth bar one 344 is fixedly connected to the upper end of the vertical guiding leg 343. The inner surface of the connecting tooth bar one 344 meshes and rotates with the outer surface of the rotating gear 345. The rotating gear 345 is rotatably installed on one side of the protective housing 33. The outer surface of the rotating gear 345 meshes and rotates with the inner surface of the connecting tooth bar two 346. A lower clamping seat 3441 is fixedly connected to the lower end of the connecting tooth bar one 344. An upper clamping seat 3461 is fixedly connected to the upper end of the connecting tooth bar two 346. Clamping pads 347 are fixedly installed on the inner surfaces of the lower clamping seat 3441 and the upper clamping seat 3461 respectively. The lower clamping seat 3441 and the upper clamping seat 3461 are respectively slidably connected to the inner wall on one side of the protective housing 33;

[0050] When the two groups of lateral guiding wheels 3311 enter the narrow channel 311 of the wire guiding channel, the supporting wing plate 34 and the connecting inclined plate 341 connecting the lateral guiding legs 331 move relatively inward synchronously. At this time, due to the design of the inclined slope of the connecting inclined plate 341, the vertical guiding wheel 342 is driven to roll on the inclined slope, and then the vertical guiding leg 343 and the connecting tooth bar one 344 are driven to lift upward. Through the matching meshing of the rotating gear 345 with the connecting tooth bar one 344 and the connecting tooth bar two 346, at this time, the connecting tooth bar one 344 and the connecting tooth bar two 346 respectively drive the lower clamping seat 3441 and the upper clamping seat 3461 to move relatively inward, so as to realize the clamping of the suture by the two groups of clamping pads 347. It should be noted that after the clamping pads 347 are clamped in place, there is still a certain compression distance for the abutting elastic wire 3321 behind the tangent cutter body 332, and the action of clamping first and then cutting can be realized, so as to avoid the rapid curling of the suture after being cut;

[0051] When it is necessary to take the suture again, the operator pushes the horizontal rod 32 in the reverse direction to make the protective shell 33 enter the wide channel 313 position of the wire channel. At this time, the two sets of lateral guide wheels 3311 are affected by the change in path width and the reverse elastic force of the abutting elastic wire 3321, driving the wire cutting knife body 332 to separate relatively and loosen the clamped suture. At this time, only one end of the suture needs to be pulled to take it again. When the surgical suture is not needed, the movable guard plate 11 is closed to achieve the closure of the suture storage box 1 to avoid dust pollution.

[0052] Embodiment 5, refer to the attached Figures 1 - 19 On the basis of the fourth embodiment, in order to realize the auxiliary disinfection when the surgical suture is taken: the auxiliary disinfection unit includes a circular limiting cylinder 4, one end of the circular limiting cylinder 4 is fixedly connected to the outer surface of the mounting frame 21, and the inner cavity of the circular limiting cylinder 4 is fixedly installed with a disinfection frame 41, and a disinfection cavity 410 is provided on the central inner wall of the disinfection frame 41, and a disinfection lamp is provided on the inner side of the disinfection cavity 410, and two groups of disinfection cavities 410 are provided, and a receiving groove is provided between the two groups of disinfection cavities 410, and the interior of the receiving groove is filled with disinfection cotton 43, and a reserved groove 4101 is provided on the central outer ring side wall of the receiving groove, and an elastic rubber seal is fixedly installed on the inner side of the reserved groove 4101 Block 4102; an annular groove 4100 is provided on the central outer ring of the disinfection rack 41, and an extrusion piece is provided on the inner side of the annular groove 4100, and the extrusion piece includes an extrusion touch rod 42 and a reset spring 421, one end of the reset spring 421 is fixedly connected to the inner wall of the annular groove 4100, and the other end of the reset spring 421 is fixedly connected to the inner ring surface of the circular limiting cylinder 4, and the outer end of the extrusion touch rod 42 is set to a rounded corner, and the outer surface of the extrusion touch rod 42 is slidably connected to the inner wall of the circular limiting cylinder 4, and the inner end of the extrusion touch rod 42 is fixedly connected to the elastic rubber sealing block 4102, and the inner surface of the elastic rubber sealing block 4102 is movably abutted against the outer surface of the disinfection cotton 43;

[0053] By installing a disinfection rack 41 inside the circular limiting cylinder 4, the disinfection lamp and the disinfection cotton 43 are accommodated to ensure that the surgical sutures are disinfected before use, simplifying the surgical disinfection steps. When the protective shell 33 moves from the narrow channel 311 of the wire channel to the wide channel 313, the claw structure formed by the four groups of claw plates 3221, such as Figure 8As shown, when the narrowing end of the claw-shaped plate 3221 abuts against the rounded corner part at the top of the extrusion contact rod 42, the extrusion contact rod 42 squeezes the elastic rubber seal block 4102 inward. At this time, the return spring 421 deforms and stretches, and the extrusion contact rod 42 that always abuts inward drives the elastic rubber seal block 4102 to deform, and squeezes the disinfected cotton 43 inside. At this time, the saturated disinfected cotton 43 will squeeze out the saturated disinfectant under the action of external force. At the same time, the disinfected cotton 43 will also be in close contact with the centrally twitched suture, ensuring that the sutures taken are double-disinfected before being drawn out, improving the comprehensiveness and effectiveness of disinfection, further enhancing the safety of medical operations, and avoiding the risk of infection at the suture incision;

[0054] After the protective housing 33 is in the narrow channel 311 position, the claw-shaped plate 3221 gradually releases the extrusion restriction on the extrusion contact rod 42, the elastic rubber seal block 4102 gradually rebounds, and releases the extrusion restriction on the disinfected cotton 43.

[0055] Embodiment Six, referring to the attached Figures 1 - 19 , on the basis of Embodiment Five, the present invention also proposes a method for using a medical suture pulling and cutting device, including the following steps:

[0056] Step 1: Install the suture loading unit: Wind the suture around the specified structure inside the loading unit, and then quickly install the loading unit on the main structure to ensure that the buckle groove and the connecting piece are correctly matched;

[0057] Step 2: Pull the suture: Pull out the required length of the suture from one end of the loading unit to ensure that the suture smoothly passes through the wire channel;

[0058] Step 3: Start the traction unit: Hold one end of the force-bearing traction component and push it towards the loading unit. At this time, the cutting piece and the moving piece inside the installation component start to work to prepare for cutting the suture;

[0059] Step 4: Clamp and cut the suture: During the movement, the auxiliary clamping component clamps the suture to prevent it from curling inward instantaneously during cutting. At the same time, the cutting piece moves relatively to complete the cutting of the suture;

[0060] Step 5: Disinfect and take the suture: After the suture is cut, the disinfectant inside the auxiliary disinfection unit is squeezed out and is in close contact with the suture to ensure that the taken suture is disinfected. Then, loosen the clamping component and pull the suture for surgical use.
