Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an endoscopic stapler with an angle adjustment function. Background Technique

[0002] An endoscopic stapler generally refers to a stapler used during endoscopic surgery. The number of staplers used in one operation is usually related to the type of surgery and the patient's condition, and commonly it is 1 - 3.

[0003] Endoscopic surgery is a minimally invasive surgery. The principle is to insert a small light source, camera, and surgical instruments through an incision of 0.5 - 1 cm. The surgical instruments are operated under the guidance of the image transmitted to the monitor to perform the surgery. The main working principle of the stapler is to use large staples to sever or anastomose the tissue.

[0004] For a conventional endoscopic stapler, the anastomosis forceps are connected to one end of the extension rod. Due to the relatively fixed structure between the two, the user cannot flexibly adjust the orientation and angle of the anastomosis forceps, and can only operate by changing the holding angle and direction, resulting in great inconvenience during use.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an endoscopic stapler with an angle adjustment function is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide an endoscopic stapler with an angle adjustment function to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: An endoscopic stapler with an angle adjustment function, including a control handle, a ratchet shaft, and a protective sleeve. A damping telescopic rod is horizontally installed at the output end of the control handle. The ratchet shaft is installed at the end of the damping telescopic rod away from the control handle, and a flipping rotating shaft is installed at the end of the ratchet shaft away from the damping telescopic rod. Moreover, an anastomosis forceps is installed at the end of the flipping rotating shaft away from the ratchet shaft, and the protective sleeve is sleeved around the anastomosis forceps.

[0008] Further, the damping telescopic rod, the ratchet shaft, and the flipping rotating shaft are all located on the same horizontal central axis, and the damping telescopic rod is fixedly connected to the control handle.

[0009] Further, the ratchet shaft and the flipping rotating shaft are integrally structured, and the damping telescopic rod is threadedly connected to the ratchet shaft.

[0010] Further, the ratchet shaft is used for the anastomosis forceps to rotate axially in the horizontal direction, and the flipping rotating shaft is used for the anastomosis forceps to swing up and down for adjustment in the vertical direction.

[0011] Furthermore, the protective sleeve includes a first buffer sleeve, a docking hole, and a second buffer sleeve. Docking holes are provided in the inner walls at the left and right ends of the first buffer sleeve, and the second buffer sleeve is connected to one side of the first buffer sleeve.

[0012] Furthermore, the protective sleeve further includes a docking pile and buffer sponges. Docking piles are provided on the inner walls at the left and right ends of the second buffer sleeve, and buffer sponges are installed inside both the first buffer sleeve and the second buffer sleeve.

[0013] Furthermore, the outer surface structure of the docking pile matches the inner surface structure of the docking hole, and the inner surface structure of the buffer sponge matches the side surface structure of the anastomosis forceps.

[0014] Furthermore, medical alcohol for disinfecting the surface of the anastomosis forceps is adsorbed inside the buffer sponge, and the buffer sponge is movably installed inside the first buffer sleeve and the second buffer sleeve.

[0015] The present utility model provides an endoscopic stapler with an angle adjustment function, having the following beneficial effects:

[0016] 1. In the present utility model, a ratchet shaft and a flipping rotating shaft are respectively installed between the damping telescopic rod and the anastomosis forceps. Due to the characteristics of its own structure, when the anastomosis forceps rotates horizontally around the ratchet shaft, while ensuring the structural stability, it prevents the structure from rotating back after the rotational adjustment, ensuring that the anastomosis forceps rotates only in a single direction of angle, preventing unnecessary mobility during use from affecting the surgical operation. By using the structure of the flipping rotating shaft, the anastomosis forceps can swing up and down within a certain angle range around the flipping rotating shaft in the vertical direction. The combined use of the above structures can provide sufficient structural flexibility for the use operation of the anastomosis forceps as much as possible, avoiding operation dead angles when operating on tissue structures, thereby affecting the surgical process.

[0017] 2. In the present utility model, a protective sleeve with a left-right combined structure is provided outside the anastomosis forceps. The first buffer sleeve and the second buffer sleeve utilize the combination of the docking hole and the docking post, enabling good structural flexibility in the combination and disassembly between the two. At the same time, since buffer sponges are installed in both the first buffer sleeve and the second buffer sleeve, the structure of the buffer sponges can provide comprehensive wrapping protection for the anastomosis forceps. By using the combination of the above structures, sufficient structural protection can be provided for the anastomosis forceps, minimizing unnecessary bumps and structural damage to the anastomosis forceps. Additionally, by injecting a certain amount of medical disinfectant alcohol into the interior of the buffer sponges, during the storage process of the entire device, due to the softness of the structure of the buffer sponges and the use of the disinfectant alcohol in cooperation, a certain degree of surface disinfection can be carried out on the anastomosis forceps, preventing unnecessary contamination and affecting the next use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0023] As Figures 1 to 3As shown in the figure, a laparoscopic stapler with an angle adjustment function includes a control handle 1, a ratchet shaft 3, and a protective sleeve 6. A damping telescopic rod 2 is horizontally installed at the output end of the control handle 1. The ratchet shaft 3 is installed at the end of the damping telescopic rod 2 away from the control handle 1, and a flipping rotating shaft 4 is installed at the end of the ratchet shaft 3 away from the damping telescopic rod 2. Moreover, a stapling forceps 5 is installed at the end of the flipping rotating shaft 4 away from the ratchet shaft 3. The protective sleeve 6 is sleeved around the stapling forceps 5. The damping telescopic rod 2, the ratchet shaft 3, and the flipping rotating shaft 4 are all located on the same horizontal central axis. The damping telescopic rod 2 is fixedly connected to the control handle 1. The ratchet shaft 3 and the flipping rotating shaft 4 are integrally structured. The damping telescopic rod 2 is threadedly connected to the ratchet shaft 3. The ratchet shaft 3 is used for the stapling forceps 5 to rotate axially in the horizontal direction, and the flipping rotating shaft 4 is used for the stapling forceps 5 to swing up and down in the vertical direction for adjustment. Since a ratchet shaft 3 and a flipping rotating shaft 4 are respectively installed between the damping telescopic rod 2 and the stapling forceps 5, the ratchet shaft 3, due to the characteristics of its own structure, enables the stapling forceps 5 to rotate axially horizontally with the ratchet shaft 3 as the center. By using the structure of the flipping rotating shaft 4, the stapling forceps 5 can swing up and down within a certain angle range in the vertical direction with the flipping rotating shaft 4 as the center.

[0024] As Figures 1 to 3 shown, the protective sleeve 6 includes a first buffer sleeve 601, a docking hole 602, and a second buffer sleeve 603. Docking holes 602 are provided on the inner walls at the left and right ends of the first buffer sleeve 601, and a second buffer sleeve 603 is connected to one side of the first buffer sleeve 601. The protective sleeve 6 further includes a docking pile 604 and a buffer sponge 605. Docking piles 604 are provided on the inner walls at the left and right ends of the second buffer sleeve 603. Buffer sponges 605 are installed inside both the first buffer sleeve 601 and the second buffer sleeve 603. The outer surface structure of the docking pile 604 matches the inner surface structure of the docking hole 602. The inner surface structure of the buffer sponge 605 matches the side surface structure of the stapling forceps 5. Medical alcohol for disinfecting the surface of the stapling forceps 5 is adsorbed inside the buffer sponge 605. The buffer sponge 605 is movably installed inside the first buffer sleeve 601 and the second buffer sleeve 603. The first buffer sleeve 601 and the second buffer sleeve 603, by using the combination of the docking hole 602 and the docking pile 604, enable good structural flexibility for combined disassembly between the two. At the same time, since buffer sponges 605 are installed in both the first buffer sleeve 601 and the second buffer sleeve 603, the structure of the buffer sponges 605 can provide all-round protection for the stapling forceps 5.

[0025] In summary, as Figures 1 to 3As shown, when the laparoscopic stapler with an angle adjustment function is in use, first, when the entire device needs to be used, the first buffer sleeve 601 and the second buffer sleeve 603, which are assembled with the use of the docking hole 602 and the docking post 604, can be split left and right, so that the anastomosis forceps 5 are disengaged from the covering of the buffer sponge 605;

[0026] Then, according to the usage requirements, first use the telescopic structure of the damping telescopic rod 2 at one end of the control handle 1 to adjust the length appropriately, then use the ratchet shaft 3 to rotate the anastomosis forceps 5 axially in the horizontal direction, and then use the flip shaft 4 to fold the anastomosis forceps 5 to an appropriate angle for subsequent surgical operations on the tissues in the patient's body.
