Description

Technical Field

[0001] The present invention belongs to the technical field of skin suturing devices, and in particular relates to a low-resistance sliding guide rail assembly for a skin suturing device. Background Art

[0002] In the field of surgical operations and trauma treatment, skin suturing is a common and important operation, the purpose of which is to promote wound healing, reduce the risk of infection and reduce scar formation. Traditional skin suturing methods mainly include manual sutures and the use of simple suturing instruments.

[0003] During use, the design of the guide rail assembly is not reasonable, resulting in greater resistance when pushing the suture staples, which not only affects the smoothness of the operation, but may also cause the suture staples to be pushed out of place or the pushing force to be uneven, thereby affecting the suturing effect.

[0004] Although existing skin staplers have improved suturing efficiency to a certain extent, when using them, doctors often rely on their experience to estimate the number and location of suture staples required for the wound, and are unable to accurately plan. This may lead to the use of too many or too few staples. Too many staples will cause irritation to the skin, and too few staples will not be able to effectively close the wound. At the same time, the lack of precise markings makes it difficult to ensure the accurate distribution of suture staples on the wound during the actual suturing process, affecting the wound healing effect. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a skin suturing device that can overcome the above problems or at least partially solve the above problems.

[0006] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a low-resistance sliding guide rail assembly for a skin stapler, comprising a housing, the housing being provided with a staple outlet, and further comprising:

[0007] an extrusion portion, rotatably connected to the housing;

[0008] A rotating connecting member is rotatably connected in the housing, and the rotating connecting member can be rotated in the housing by squeezing the squeezing portion;

[0009] A base, detachably connected to the bottom of the shell;

[0010] An ejector pin is slidably connected to the base, one end of the ejector pin abuts against the rotating connector. When the extrusion portion squeezes the rotating connector, the ejector pin slides on the base, thereby pushing the suture staple on the base toward the staple outlet.

[0011] A nail forming part is fixedly connected to the base and is located at the nail outlet;

[0012] The nail pushing member is slidably connected to the nail outlet. By rotating the connecting member, the nail pushing member can be moved upward to leak out the nail outlet. At this time, the suture nail is pushed out by the nail pushing member. Then, as the extrusion part is reset, the nail pushing member is driven to reset. At the same time, the nail pushing member is reset and then squeezes the suture nail below. Through the cooperation of the nail pushing member and the nail forming member, the suture nail is deformed, and then the patient's skin is sutured.

[0013] Furthermore, a spring member is clamped on the rotating connecting member, and the other end of the spring member is against the inside of the shell. By squeezing the extrusion part with the hand, the rotating connecting member is rotated, and the spring member is squeezed and deformed. When the hand subsequently leaves the extrusion part, the spring member will drive the rotating connecting member to reset.

[0014] Furthermore, the shell is equipped with a camera above the nail outlet and a nozzle on the side of the nail outlet. During initial use, the camera is used to record the damaged length of the skin and transmit it to the computer. Then, the shell is moved again and the nozzle is used to mark the side where the suture staples are needed. Finally, the suture staples are inserted at the parallel position of the mark.

[0015] Furthermore, a roller is installed on the nozzle. When taking pictures of the damaged part of the patient's skin through the camera, a line is first drawn on the damaged side, and then the roller is placed on the line and moved along the line.

[0016] Furthermore, a mounting portion 1 is fixedly connected to the shell, a mounting groove 1 is provided on the mounting member 1, and a mounting member 1 matching the mounting groove is fixedly connected to the camera.

[0017] Furthermore, a card block is slidably connected to the mounting portion, and a card slot matching the card block is provided on the mounting member. By inserting the card block into the card slot, the camera can be locked and fixed, and a pull plate is fixedly connected to the end of the card block away from the mounting slot.

[0018] Furthermore, a second mounting portion is fixedly connected to the shell, a second mounting groove is provided on the second mounting portion, a mounting plate is fixedly connected to the nozzle, and a second mounting piece matching the second mounting groove is provided on the mounting plate.

[0019] Furthermore, a clamping block 2 is slidably connected in the second mounting portion, and a clamping slot 2 matching the clamping block 2 is provided on the second mounting member. By inserting the clamping block 2 into the clamping slot 2, the nozzle can be locked and fixed, and a pull plate 2 is fixedly connected to the end of the clamping block 2 away from the second mounting slot.

[0020] Furthermore, a connecting rod is fixedly connected to the second mounting portion, an inserting rod is installed on the connecting rod, and the roller is rotatably connected to one end of the inserting rod.

[0021] Furthermore, the connecting rod is provided with a slot, the insertion rod is slidably connected in the slot, and the connecting rod is threadedly connected with a locking bolt, and the locking bolt is used to fix the insertion rod on the connecting rod.

[0022] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: the present invention can automatically push out the suture nail and deform it through the cooperation of the extrusion part, the rotating connecting part and other components to suture the patient's skin. At the same time, through the cooperation of the camera and the nozzle, the damaged part of the patient's skin can be photographed before suturing, and the optimal suture area can be obtained by computer, which facilitates the suturing of the patient's skin.

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0038] Example: Refer to Figure 1-12A low-resistance sliding guide rail assembly for a skin stapler includes a shell 1, which is provided with a nail outlet, and further includes: an extrusion portion 2, which is rotatably connected to the shell 1; a rotating connector 3, which is rotatably connected in the shell 1, and by squeezing the extrusion portion 2, the rotating connector 3 can be rotated in the shell 1; a base 6, which is detachably connected to the bottom of the shell 1; a thimble 7, which is slidably connected to the base 6, and one end of the thimble 7 is against the rotating connector 3. When the extrusion portion 2 squeezes the rotating connector 3, the thimble 7 slides on the base 6, thereby The suture nail on the base 6 is pushed toward the nail outlet; the nail forming part 5 is fixedly connected to the base 6, and the nail forming part 5 is located at the nail outlet; the nail pushing part 4 is slidably connected to the nail outlet, and by rotating the rotating connecting part 3, the nail pushing part 4 can be moved upward to leak the nail outlet. At this time, under the action of the nail pushing part 4, the suture nail is pushed out, and then with the resetting of the extrusion part 2, the nail pushing part 4 is driven to be reset, and at the same time, the nail pushing part 4 is reset, and then the suture nail below is squeezed, and the suture nail is deformed through the cooperation of the nail pushing part 4 and the nail forming part 5, and then the patient's skin is sutured.

[0039] When the device is in use, the medical staff holds the skin suture device, brings the shell 1 close to the patient's skin wound, and squeezes the squeezing part 2 with their hands. The squeezing part 2 rotates to drive the rotating connecting part 3 to rotate in the shell 1. The rotating connecting part 3 pushes the ejector part 7 to slide on the base 6, pushing the suture staple toward the staple outlet. At the same time, the rotating connecting part 3 causes the staple pushing part 4 to move upward to expose the staple outlet. The staple pushing part 4 pushes the suture staple out. When the squeezing part 2 is reset, the staple pushing part 4 is also reset and squeezes the suture staple below, causing it to deform under the action of the staple forming part 5, completing the suturing of the skin.

[0040] A spring member 8 is clamped on the rotating connecting member 3, and the other end of the spring member 8 is in contact with the inside of the shell 1. By squeezing the extrusion part 2 by hand, the rotating connecting member 3 is rotated, and the spring member 8 is squeezed and deformed. When the hand subsequently leaves the extrusion part 2, the spring member 8 will drive the rotating connecting member 3 to reset.

[0041] When performing skin suturing operations, medical staff squeeze the squeezing part 2, rotate the rotating connecting part 3 and squeeze the spring part 8. After completing one suturing operation, they release the squeezing part 2, and the elastic force of the spring part 8 pushes the rotating connecting part 3 to reset, so that all components return to their initial positions, making it convenient for medical staff to perform the next skin suturing operation.

[0042] The shell 1 is equipped with a camera 102 above the nail outlet and a nozzle 108 on the side of the nail outlet. During initial use, the camera 102 is used to record the length of the skin damage and transmit it to the computer. Then, the shell 1 is moved again and the nozzle 108 is used to mark the side where the suture staples are needed. Finally, the suture staples are inserted at the parallel position of the mark.

[0043] During initial use, the medical staff holds the skin stapler, points the camera 102 at the damaged part of the patient's skin, starts the camera 102 to record the length of the damaged skin, and transmits the captured image information to the computer via a data cable for storage and analysis. The movement at this time needs to be slow to facilitate accurate shooting by the camera 102 and to facilitate subsequent marking of the patient's skin surface to avoid skewed or even incorrect markings caused by excessive movement. Then the medical staff slowly moves the skin stapler to align the nozzle 108 with the side of the place where the suture is needed, and sprays a liquid that does not affect the patient's recovery through the nozzle 108 to mark the skin surface, making it convenient for subsequent accurate suture operations in the parallel position of the mark.

[0044] The camera 102 and the nozzle 108 must be connected to special pipelines. The camera 102 is connected to the data cable for transmitting signals, and the nozzle 108 needs to be connected to the connecting pipe, which is connected to the water pump located in the dye box. The dye in the dye box uses a sterile liquid after disinfection, which can mark the surface of human skin without affecting the patient's skin healing and will not cause allergic reactions. The water pump is connected to a computer, and the computer controls the opening of the water pump.

[0045] Before use, a fluorescent dye, such as indocyanine green (ICG), is injected around the wound. Healthy tissue appears bright due to adequate blood supply, while ischemic or necrotic tissue appears dim. The camera 102 captures the fluorescent signal through a filter, and the auxiliary algorithm accurately divides the suture boundary. The integrated Raman spectroscopy probe analyzes the chemical composition of the tissue, such as protein and lipid content, in real time to distinguish normal skin from inactive tissue, similar to the real-time pathological analysis during tumor resection.

[0046] A roller 115 is installed on the nozzle 108. When the camera 102 is used to take a picture of the damaged part of the patient's skin, a line is first drawn on the damaged side, and then the roller 115 is placed on the line and moved along the line.

[0047] A roller 115 is installed on the nozzle 108. When in use, the medical staff first takes a photo of the damaged area of ​​the patient's skin through the camera 102, and then operates the nozzle 108 to draw a mark on the damaged side. After that, the roller 115 is placed against the mark and the skin stapler is pushed along the mark. Since the roller 115 contacts and rolls with the mark, it can play an auxiliary positioning role, so that the skin stapler can move more accurately along the direction of the mark during the movement, thereby ensuring the accuracy of subsequent suturing operations.
