Description

Technical Field

[0001] The utility model relates to the technical field of anastomosis devices, in particular to a guide component of a laparoscope anastomosis device. Background Art

[0002] Laparoscopic staplers (laparoscopic cutting staplers and disposable stapler cartridges) are key instruments in laparoscopic surgery. They replace traditional manual suturing, using titanium staples to separate or staple tissue. They are simple and quick to operate, significantly shortening operative time. Laparoscopic staplers facilitate anastomosis in narrow, deep surgical areas, which is difficult to perform manually. They are also accurate, secure, and reliable, significantly reducing the incidence of anastomotic leaks.

[0003] Currently, existing laparoscopic staplers typically require a guide component during activation. This component serves two primary functions: 1. Preventing rotation of the cylindrical firing rod, which is fitted to the device. 2. It also acts as a transmission mechanism to activate the firing safety after the components are docked. Most existing guide components are constructed from two separate metal and plastic parts, requiring two different manufacturing processes. This complex process also requires ensuring precise fit between the metal and plastic components, significantly increasing production and processing costs.

[0004] Therefore, it is necessary to design a guide component of a laparoscopic stapler to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to propose a guide component for a laparoscopic stapler in order to solve the problems of complex production process, high matching precision and high production cost of existing guide components.

[0006] The technical solution of the utility model is: a guide component of a laparoscopic stapler, characterized in that it comprises a strip-shaped guide plate; one end of the guide plate is upwardly provided with a guide structure arranged in an integral manner with the guide plate.

[0007] The guide structure is formed by bending lugs symmetrically arranged on both sides of the guide plate upward.

[0008] The lug is T-shaped.

[0009] Both ends of the lug are bent upward.

[0010] The end portion of the guide plate is configured to be a flat surface.

[0011] The guide plate is made of 304 stainless steel.

[0012] The length of the guide plate is 35-45 mm, and the width is 3.5-5.5 mm; the distance between the bottom surface of the guide plate and the top surface of the guide structure is 3-5 mm.

[0013] By adopting the above technical solution, the utility model has the following beneficial effects: (1) The guide component of the utility model integrates the guide structure and the guide plate, which saves the steps of assembly and matching during production, greatly reduces the production difficulty, and lowers the production cost.

[0014] (2) The guide structure of the present invention is formed by bending the lugs symmetrically arranged on both sides of the guide plate upward. The guide structure is formed by bending, the process is relatively simple, and the production is more convenient.

[0015] (3) The lug of the present invention is T-shaped, which makes it easier to bend the lug upward.

[0016] (4) The end of the guide plate of the present invention is configured to be flat so that it can better abut against other components.

[0017] (5) The guide plate of the present invention is made of 304 stainless steel, which has a longer service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] (Example 1)

[0024] See Figure 1 and Figure 2 The guide component of a laparoscopic stapler of this embodiment is characterized by comprising a strip-shaped guide plate 1; a guide structure 2 integrally provided with the guide plate 1 is upwardly provided at one end of the guide plate 1.

[0025] Furthermore, the guide structure 2 is formed by bending upwards the lugs symmetrically arranged on both sides of the guide plate 1, which makes production more convenient and more efficient.

[0026] Furthermore, the lug is T-shaped, which makes it easier to bend the lug upward.

[0027] Furthermore, both ends of the lug are bent upwards to avoid interference with the anastomosis device during guidance, thereby improving the guiding effect.

[0028] Furthermore, the end of the guide plate 1 is configured to be a plane so that both ends of the guide plate 1 can better abut against the anastomosis device's anvil assembly and the limiting rod.

[0029] Furthermore, the guide plate 1 is made of 304 stainless steel, which has a longer service life.

[0030] Furthermore, the length of the guide plate 1 is 35-45 mm, preferably 40 mm, and the width is 3.5-5.5 mm, preferably 4.5 mm; the distance between the bottom surface of the guide plate 1 and the top surface of the guide structure 2 is 3-5 mm, preferably 4 mm.

[0031] The guide component of this embodiment integrates the guide structure 2 and the guide plate 1 into one piece, which saves the assembly steps during production. During installation, it is only necessary to pass the guide plate 1 through the inner core groove and place it on the plane of the firing rod 3. The guide structure 2 moves back and forth in the groove of the inner core, which makes installation more convenient and greatly reduces the difficulty of production. At the same time, the guide structure 2 is formed by the upward bending of the lugs symmetrically arranged on both sides of the guide plate 1, which makes production more convenient, more efficient, and has better economic effects.

[0032] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
