Problems solved by technology

Recycling and destruction is a major problem, which not only causes environmental pollution but also is not conducive to saving resources and reducing consumption, and the cost remains high
Developing countries often turn to low-cost reusable PPH staplers due to high costs, but this is obviously not conducive to preventing cross-infection
At the same time, risks associated with

Embodiment 1

[0036] Example 1 as figure 1 Shown in -6: an electrothermal energy nailless anal hemorrhoid stapler, including a grab tube, a rear handle and a front handle. The rear end of the grab tube 5 is connected with the rear handle 10 as a whole, and the trumpet-shaped front end of the grab tube 5 is fixedly connected with one end of the electrothermal energy matching cutting head 2, and the other end of the electrothermal energy matching cutting head 2 is provided with an oblique crescent edge; The two sides of the trumpet-shaped front end of the grab tube 5 are provided with drawing line slots 3, and the middle part of the grab tube 5 is provided with a window 6; Cavity is provided with the spherical adjustment nut 8 of rectangular screw thread 17 and is positioned at the rear end of grabbing pipe 5 .

[0037] The center rod 4 placed in the grab tube 5 is in clearance fit with the inner cavity of the grab tube 5, the front end of the center rod 4 is provided with a semi-circular ba...

Embodiment 2

[0039] Example 2 as figure 1Shown in -6: a kind of operation method using the electrothermal energy nail-free anal hemorrhoid stapler described in embodiment 1 is as follows:

[0040] [1] Insert the threaded rear end of the center rod 4 from the electrothermal energy anastomosis cutting head 2 at the front end of the grab tube 5, pass through the through hole 14 of the front handle 13 and screw the looseness of the adjusting nut 8 located at the rear end of the grab tube 5, and then The hemisphere 1 of the central rod 4 is close to the anal hemorrhoid;

[0041] [2] Use a wire hook to pull out the anal hemorrhoid purse suture thread head from the bilateral draw-out slot hole 3 of the electrothermal anastomosis cutting head 2 and tighten it;

[0042] [3] Tighten the adjusting nut 8 until the marking line 16 of the central rod 4 located in the inner cavity of the grab tube 5 is observed through the window 6 in the middle of the grab tube 5 and is in place;

[0043] [4] Turn the...

Abstract

The invention relates to an electrothermal non-nail hemorrhoid stapler and an operation method thereof. The electrothermal non-nail hemorrhoid stapler comprises a pipe, a rear handle and a front handle. The rear end of the pipe is connected with the rear handle as a whole, the horn-shaped front end of the pipe is in fixed connection with an electrothermal anastomotic heading, and the front handle is hinged with the rear end of the pipe through a pin roll; the front end of a center rod arranged in the pipe is provided with a hemi-pellet which is in fit with the outer diameter of horn-shaped front end of the pipe, and the rear end of the center rod is in threaded connection with an adjusting nut; a wire connected with a socket at the lower end of the rear handle is connected with a heating element arranged on the electrothermal anastomotic heading to form a loop. The electrothermal non-pin hemorrhoid stapler adopts safe minimally invasive technologies of a electrothermal cutting and a electrothermal anastomosis, thereby avoiding the medical risk and post-operation safety problems due to titanium nails in the traditional nail hemorrhoid stapler; ninety-five percent of components are made with plastic, and are light in weight, low in cost, convenient to be destroyed and recycled in the renewable resources and beneficial for environmental protection.

Description

technical field [0001] The invention relates to a surgical medical instrument, in particular to an electrothermal energy nailless anal hemorrhoid stapler and an operating method thereof. Background technique [0002] Usually in hospital clinical suspension type anal hemorrhoidectomy (abbreviation PPH operation) widely adopts nail type stapler, this instrument product is divided into one-time use and repeated use two big classes. Their common feature is that according to the similar working principle of the stapler, 26-32 small titanium nails are nailed in a circular and staggered manner through the nail pusher to close the part of the intestinal wall endometrial tissue to be removed (commonly known as "pouch") , thus playing the role of sealing the blood vessels in the tissue and connecting the suspending membrane of the rectal wall. After sealing, the cylindrical ring cutter built in the staple pusher completely cuts off the purse to complete the operation. [0003] After...
