Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a long kiss-type suturing device capable of multi-angle operation. Background Art

[0002] Surgical staplers are medical devices used for surgical suturing. Staples are staples specifically used in surgery to replace sutures to close skin wounds, connect or remove parts of the intestine or lung. The suturing technique of the suture is a focus of debate. Complications of suture surgery are occasionally common, mainly causing leakage, bleeding, stenosis, ulcers, and bleeding. Due to the low incidence of complications in suture surgery, it has not attracted sufficient attention from the industry. Once it occurs, it will add many unexpected difficulties and processes to the treatment. Among them, postoperative suture leakage is one of the most common and serious surgery-related complications, which can cause life-threatening septic complications, including mediastinitis. According to statistics, the suture leakage rate caused by thoracic esophagogastric anastomosis is as high as 5-40%.

[0003] Chinese invention patent publication number CN117838221A discloses a continuous soft tissue suturing device, which relates to the technical field of medical devices. The continuous soft tissue suturing device of the present invention comprises a suturing head mechanism and a handle transmission mechanism, which is driven and controlled by the handle transmission mechanism. The continuous soft tissue suturing device of the present invention can be used for gastrointestinal suturing. The entire device has a simple structure and is easy to operate, enabling quick and simple continuous suturing while reducing the likelihood of surgical complications.

[0004] However, in this stapler, the suturing head mechanism and the handle transmission mechanism are fixedly connected, and the placement and state of the suture staples within the suturing head mechanism are fixed. In other words, the suture staples can only be positioned in one state when being pushed out. A limitation of this stapler is that the operator can only adapt to different suturing positions by changing their standing position, or by changing the position and angle of the stapler's hand, which brings inconvenience to the surgical suturing operation. Utility Model Content

[0005] In order to solve the above problems existing in the prior art, the utility model provides a long kiss-type stapler that can be operated at multiple angles.

[0006] The above-mentioned problem of the present invention is solved by the following technical solutions:

[0007] A long kiss type stapler capable of multi-angle operation, comprising:

[0008] A suturing head module, comprising at least a base having a staple cartridge and suturing staples placed in the staple cartridge;

[0009] The handle module includes a grip connected to the suturing head module and a trigger hinged on the grip, the interior of the grip is connected to the staple cartridge, and is provided with a drive assembly to push out the staples to suturing the patient's soft tissue;

[0035] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0036] like Figure 1-7 As shown, the following embodiment discloses a long kiss type stapler that can be operated at multiple angles.

[0037] Example 1

[0038] A long kiss type stapler capable of multi-angle operation, comprising:

[0039] The suturing head module comprises at least a base 100 having a staple cartridge 200 and staples placed in the staple cartridge 200;

[0040] The handle module includes a grip 300 connected to the suturing head module and a trigger 400 hinged on the grip 300. The interior of the grip 300 is connected to the staple cartridge 200 and is provided with a drive assembly to push out the staples to suturing the patient's soft tissue.

[0041] The base 100 and the handle 300 are rotatably connected and provided with a damping structure.

[0042] The above is the basic solution of this embodiment.

[0043] Specific reference Figure 1 As shown, the suturing head module is assembled on the head of the handle module, opposite to the trigger 400 on the handle module, and the head of the suturing head module is used to push out the suture nails;

[0044] During operation, the surgical operator presses the trigger 400 and rotates the trigger 400 toward the side of the handle 300. The trigger 400 actuates the drive assembly inside the handle 300, and the drive assembly drives the suture staples in the staple magazine 200, so that the suture staples are pushed out from the head of the suture head module to suture the patient's soft tissue.

[0045] When it is necessary to suture soft tissue modules at different positions, such as the side of the body surface, the surgical operator holds the base 100 of the suture head module and rotates it. The base 100 drives the suture staples in the staple magazine 200 to rotate together. When it is rotated to the appropriate angle, the position of the suture staples when they are pushed out is just perpendicular to the surface of the suture opening, that is, it is rotated to the appropriate position. At this time, due to the effect of the damping structure, the suture head cannot rotate relative to the handle module, and the surgical operator can perform the suture operation on the suture opening.

[0046] Based on the above arrangement, during the suturing operation, the operator can keep the suture staples in the appropriate position when pushing them out without changing their standing position or holding method, thereby ensuring the suturing requirements of the suture site, reducing complications caused by inappropriate suture position or suture staple position, and ensuring the integrity and effectiveness of the suturing operation;

[0047] At the same time, the damping structure is used to automatically limit the suturing head module and the handle module, avoiding the suturing deviation caused by the suturing head module rotating relative to the handle module during the suturing operation, further ensuring the integrity of the suturing operation.

[0048] In this embodiment, the suturing method of the suturing device is consistent with that of the suturing device in the prior art and will not be described in detail here.

[0049] The end surface of the handle 300 connected to the base 100 is a first mating end surface 301, and the first mating end surface 301 is provided with an assembly hole 302 capable of accommodating the sliding of the driving assembly;

[0050] A guide neck 110 is provided on the second mating end face 102 on the base 100 that is connected to the first mating end face 301 and can extend into the handle 300 through the assembly hole 302. A limiting structure 111 is provided at the end of the guide neck 110 so that the guide neck 110 cannot withdraw from the assembly hole 302 along the axial direction.

[0051] Specific reference Figure 2-Figure 4 As shown, to ensure the stability of the connection, the first mating end face 301 and the second mating end face 102 are tightly attached, and the guide neck 110 on the second mating end face 102 can pass through the assembly hole 302 into the interior of the handle module, and is limited by the limiting structure 111, so that the guide neck 110 cannot withdraw from the handle module, thereby assembling the suture head module and the handle module into one.

[0052] Preferably, in this embodiment, the limiting structure is a limiting ring 111 extending outward from the end of the guide neck 110;

[0053] The outer diameter of the limiting ring 111 is larger than the diameter of the assembly hole 302 .

[0054] Specific reference Figure 4 As shown, the limiting structure is set as a limiting ring with a diameter larger than the aperture of the assembly hole 302, and the limiting ring is set on the outer periphery of the end of the guide neck 110;

[0055] To ensure smooth rotation, in this embodiment, the outer diameter of the guide neck 110 is consistent with the inner diameter of the assembly hole 302, or slightly smaller than the inner diameter of the assembly hole 302, so that the guide neck 110 does not scratch the wall of the assembly hole 302 when rotating in the assembly hole 302, thereby reducing wear of the assembly hole 302;

[0056] The outer diameter of the limiting ring 111 is larger than the assembly hole 302 . Therefore, the limiting ring 111 cannot escape from the assembly hole 302 , thereby limiting the guide neck 110 in the assembly hole 302 .

[0057] In this embodiment, the base 100 , the guide neck 110 and the limiting ring 111 are integrally formed.

[0058] In other embodiments, the limiting structure 111 may also be configured as a protrusion extending radially outward from the periphery of the guide neck 110 , and the distance from the outermost end of the protrusion to the center of the guide neck 110 may be greater than the assembly hole 302 .

[0059] In this embodiment, the specific implementation of the damping structure is as follows: the damping structure is a damping ring 500 arranged on the first mating end face 301 / the second mating end face 102; the second mating end face 102 / the first mating end face 301 is provided with a damping groove 103 that cooperates with the damping ring 500.

[0060] Specific reference Figure 3-Figure 5 As shown, in this embodiment, the damping ring 500 is protrudingly provided on the first mating end face 301, and the damping groove 103 mating with the damping ring 500 is recessed on the second mating end face 102. In this way, during assembly, the damping ring 500 is inserted into the damping groove 103. At the same time, the first mating end face 301 and the second mating end face 102 can still be tightly fitted or fitted with a small gap.

[0061] When the base 100 rotates under the action of external force, the damping ring 500 slides in the damping groove 103, and the friction between the outer surface of the damping ring 500 and the damping groove 103 generates damping. When the external force disappears, the friction between the damping ring 500 and the damping groove 103 causes the base 100 and the handle 300 to be in a relatively static state, and the base 100 cannot rotate relative to the handle 300 under the action of damping.

[0062] To facilitate the assembly of the base 100 and the handle 300 , in this embodiment, the handle 300 is formed by splicing two symmetrically arranged first shells 310 and second shells 320 .

[0063] Specific reference Figure 5 As shown, the first shell 310 and the second shell 320 divide the assembly hole 302 into two half holes, left and right. During assembly, the guide neck 110 is assembled into one of the half holes, and then the other half hole is spliced ​​together.

[0064] In other embodiments, the base 100 may also be divided into two symmetrical left and right shells for splicing.

[0065] In this embodiment, the specific implementation of the drive assembly is as follows: the drive assembly at least includes a push rod 600 that can be actuated by the handle 300, and a drive channel connecting the nail magazine 200 and the inner cavity of the handle 300 is provided in the guide neck 110. The push rod 600 can extend into the nail magazine 200 through the drive channel to drive the suture nails in the nail magazine 200 out.

[0066] Specific reference Figure 4 As shown, the trigger 400 is hinged on the grip 300, and a brake tongue and a grip portion 420 are respectively provided on both sides of the hinge portion. The grip 300 includes a main body portion for accommodating the drive assembly and a hand-held portion, and the main body portion and the hand-held portion are arranged in an L shape.

[0067] The gripping portion 420 is pressed toward the handheld portion to rotate the handle 300 around the hinge portion. At this time, the actuating tongue 410 rotates to drive the push rod 600 toward the suture head module to push out the suture staples in the staple cartridge 200 .

[0068] In this embodiment, an actuating groove is provided on the push rod 600 , and the actuating portion extends into the actuating groove to drive the push rod 600 .

[0069] Example 2

[0070] The only difference between this embodiment and embodiment 1 is that another specific implementation of the damping structure is provided. The specific solution is as follows:

[0071] The damping structure is a damping washer 700 provided between the first mating end surface 301 and the second mating end surface 102 .

[0072] Specific reference Figure 6 As shown, the damping washer 700 is installed on the first mating end face 301 or the second mating end face 102. After assembly is completed, the damping washer 700 is located between the first mating end face 301 and the second mating end face 102. During the rotation of the base 100, the friction between the first mating end face 301 and the damping washer 700 generates damping, and at the same time, the friction between the second mating end face 102 and the damping washer 700 generates damping; therefore, when the external force disappears, the friction between the first mating end face 301, the second mating end face 102 and the damping washer 700 enables the base 100 and the handle 300 to be in a relatively static state.

[0073] Example 3

[0074] The difference between this embodiment and the above two embodiments is that another specific implementation method of the damping structure is provided. The specific solution is as follows:

[0075] The damping structure is a damping washer 700 embedded on the first mating end surface 301 / the second mating end surface 102 .

[0076] Specific reference Figure 7 As shown, in this embodiment, an embedding groove 301.1 is provided on the first mating end face 301, and the damping washer 700 is embedded in the embedding groove 301.1; the base 100 and the handle 300 are assembled, the first mating end face 301 and the second mating end face 102 are in contact, and the second mating end face 102 and the damping washer 700 are in contact, and friction generates damping during relative rotation; when the base 100 is not subjected to external force, the friction between the second mating end face 102 and the damping washer 700 enables the base 100 and the handle 300 to be in a relatively static state.

[0077] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
