Problems solved by technology

[0003] 1) During surgery, for thicker gastric tissue, when the tissue is closed and compressed, the tissue has a greater reaction force against the instrument. Since the front end of the instrument is designed as a cantilever, the rigidity of the instrument is poor, and the anvil will be warped and deformed to make the front end anastomose The height H becomes larger, and at the same time, it will also shift left and right, resulting in poorly formed staples, unable to effectively anastomose the tissue, affecting the quality of the operation, and affecting the safety of the operation
[0004] 2) ...

Embodiment Construction

[0017] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0018] Such as Figure 2~4 As shown, a surgical cutting stapler includes an abutment base 2, an assembly base 3, an anastomosis assembly 5, a firing device 6 and a closing device for manipulating an abutment base 2. The anastomosis assembly 5 is installed on the assembly base 3. The head and the middle of the component seat 3 are each provided with a positioning groove 3-1, and correspondingly, two positioning pins 2-1 that cooperate with the positioning groove 3-1 are provided on the nail abutment seat 2.

[0019] Such as image 3 As shown, the closing device for operating the abutment base 2 is composed of a closing knob 1, a closing screw 13 and a transmission member. The closing knob 1 and the closing screw 13 are threadedly connected. The front end of the closing screw 13 is hinged with the transmission member, and the transmission member is A pin shaft 14 ...

Abstract

The invention relates to a cutter stapler for surgery. The cutter stapler comprises a pin holder (2), an assembly base (3), an osculating assembly (5), a firing gear (6) and an occlusion device for operating the pin holder (2), wherein the osculating assembly (5) is installed on the assembly base (3), the head part and the middle part of the assembly base (3) are respectively provided with a positioning slot (3-1), and positioning pins (2-1) matched with two positioning slots (3-1) are correspondingly arranged on the pin holder (2). When the cutter stapler is used for osculating thick tissue, a pin pushing part and the osculating assembly can be accurately positioned, the rigidity of the stapler is improved, and the uniformity of front and back inosculation heights and the forming quality of osculating pins can be ensured.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a cutting stapler for surgery. Background technique [0002] The cutting stapler is a medical device that is often used during surgical operations on physiological tissues such as the digestive tract. However, when performing transectary anastomosis for gastric tissue, use the existing cutting stapler (see figure 1 ) There are the following disadvantages: [0003] 1) During surgery, for thicker gastric tissues, when closing and compressing the tissue, the reaction force of the tissue on the device is greater. Because the front end of the device is designed with a cantilever, the rigidity of the device is poor, and the nail seat will be warped and deformed, making the front end anastomosis The height H becomes larger, and it also shifts left and right at the same time, resulting in poor formation of the staples and ineffective anastomosing of the tissue, affecting the quality of the oper...
