Embodiment

[0046] Embodiment: a kind of surgical operation medical instrument.

[0047] This embodiment provides an optional figure 1 The tubular stapler shown, the partial enlarged view of detail A of the above tubular stapler is shown in Figure 1-A as shown, Figure 1-A The schematic diagram of the Figure 1-B As shown, including firing handle 1, shell 2 and safety switch device 3, also includes such as diagram 2-1 Inner insurance block 4 shown, as image 3 Shown main living bar 5 and as Figure 4 Shown secondary live bar 6. Another three-dimensional schematic diagram of the above-mentioned inner insurance block 4 is shown in Figure 2-2, as Figure 1-A and Figure 1-B As shown, the above-mentioned inner safety block 4 is in the initial state of the above-mentioned tubular stapler against the above-mentioned firing handle 1 to prevent firing, and the above-mentioned inner safety block 4 is passed as Figure 5 The shown first torsion spring 7 is rotatably connected with the abo...

Embodiment 2

[0065] This embodiment provides an optional tubular stapler, the safety switch device 3 of the tubular stapler includes: a base 3.1; a lever 3.2, the lever 3.2 is connected to the base 3.1 through a connecting part 3.21 , the above-mentioned driving rod 3.2 rotates around the above-mentioned connecting member 3.21, the first end 3.24 of the above-mentioned driving rod is located inside the above-mentioned base 3.1, and the second end 3.25 of the above-mentioned driving rod is located outside the above-mentioned base 3.1; The component is located inside the above-mentioned base 3.1, the above-mentioned first end 3.24 of the above-mentioned driving rod 3.2 is in contact with the above-mentioned limiting member, when the above-mentioned driving rod 3.2 rotates to the first limiting position with the above-mentioned connecting member 3.21 as the axis, the above-mentioned The limiting component and the first part 3.11 of the above-mentioned base 3.1 form a clamping connection with t...

Embodiment 3

[0067] On the basis of Embodiment 2, the above-mentioned limiting component includes: a limiting movement part. The interior is located at the first position. When the above-mentioned lever 3.2 rotates from the first limit position to the second limit position with the above-mentioned connecting part 3.21 as the axis, the limit movement part first moves from the first position to the second limit position. The opposite side of the first end portion 3.24 moves to the second position, and then moves from the second position to the first position.

Abstract

The invention belongs to the technical field of medical devices, and provides a surgical medical device. The surgical medical device comprises a firing handle, a shell, an inner safety block, a main moving rod and a secondary moving rod, wherein the inner safety block props against the firing handle at an initial state of the surgical medical device to prevent the firing handle from firing, and the inner safety block is rotationally connected with the shell through a first elastic component; the main moving rod is rotationally connected with the shell and pushes the inner safety block, so that the inner safety block cannot prevent the rotation of the firing handle; and the secondary moving rod is rotationally connected with the shell through a second elastic component. The surgical medical device can be applied to various surgical medical devices, namely, the working principle is as follows: holding the firing handle, thereby completing the firing; and loosening the firing handle, so that the firing handle automatically restores, and various surgical medical devices can be tube-type anastomats, anastomats for procedure for prolapse and hemorrhoids, sutures, single clip appliers and the like.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a surgical medical instrument. Background technique [0002] In surgical operations, surgical medical devices have become indispensable medical devices in surgical operations, such as tubular staplers, hemorrhoidal mucosal staplers, linear staplers, single-shot clamps, etc. These surgical medical devices are Some have firing safety, some do not have firing safety, and some surgical medical devices with firing safety do not have automatic reset function. Linear staplers and single-shot clip appliers do not have pre-fire safety. The safety before firing can prevent surgical medical instruments from being misfired and affect the operation, while the firing safety that can be automatically reset improves the automatic performance of the device and is more convenient for the operator to use. [0003] Therefore wait to propose a kind of surgical operation medi...
