Description

Technical Field

[0001] This utility model relates to an endoscopic anastomosis device, and more particularly to an electric closing forceps oral endoscope anastomosis device. Background Technology

[0002] Electric laparoscopic staplers, as a medical alternative to manual cutting, are widely used in various open and minimally invasive surgeries. The working principle of the mainstream electric laparoscopic staplers on the market is mainly based on manually turning the closing handle, which causes the closing linkage connected to the closing handle to push the outer tube on the tube sleeve to reciprocate, thereby achieving the function of clamping and opening the jaws and holding the tissue. The clamping force of the products on the market cannot be adjusted according to the tissue thickness, resulting in either insufficient clamping or excessive clamping force. If the tissue is too thick, the doctor needs to use a lot of force to hold the tissue, which poses a risk and cannot achieve a precise opening and closing state. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art by providing an electric closing forceps oral endoscope stapler, which solves the problem that the clamping force of the stapler is not adjustable and cannot be accurately opened and closed.

A gun core card is inserted into the gun core slot. The rear end of the outer tube passes through the gun core card and the outer tube through hole. A closing compression spring is sleeved on the outer wall of the rear end of the outer tube. The closing compression spring is disposed between the compression cavity and the gun core card.

[0006] Furthermore, the connection between the electric cylinder push rod and the connecting rod is made by a wing screw.

[0007] Furthermore, a fixing ring is provided at the rear end of the bracket, and the electric cylinder is fixed on the fixing ring.

[0008] Furthermore, a pressure sensor is provided on each side of the rear end of the anvil at the hinge, and the pressure sensor is connected to the circuit board for control.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] In response to the needs of endoscopic anastomosis devices, the designer of this utility model has innovatively proposed an electric closing forceps oral endoscope anastomosis device, which can adjust the clamping force and precisely control the opening and closing.

[0026] like Figures 1 to 9As shown, an electric closure forceps oral endoscope stapler includes a stapler gun handle, a bracket 4 located at the upper end of the handle, an outer tube 10 located at the front end of the bracket 4, and a jaw 30 located at the front end of the outer tube 10. The jaw 30 includes a staple cartridge seat and a staple abutment seat 31, which are arranged vertically and hinged at their rear ends. The staple cartridge seat has a staple cartridge. The bracket 4 has a compression chamber 41 at its front end, a circuit board 3 at its top middle section, and an electric cylinder 6 connected to the circuit board 3 at its rear end. The compression chamber 41 has a pressing assembly 1 connected to the electric cylinder push rod 51. The front end of the pressing assembly 1 is connected to the outer tube 10. The bracket 4 has a retraction button 2 connected to the circuit board 3 on its side middle section. The bracket 4 has an activation button 7 rotatably connected to its bottom. The bracket 4 has an activation link 9 rotatably connected to the activation button 7 above it. The activation link 9 is connected to the circuit board 3. The bracket 4 has a safety button 8 rotatably connected to the bottom of the bracket at the rear end of the activation button 7 to ensure that the activation button 7 is not accidentally activated.

[0027] The bracket 4 is provided with an excitation button mounting hole 43, and the excitation button 7 is rotatably connected to the bracket 4 through the excitation button mounting hole 43 via a connecting shaft.

[0028] The pressing assembly 1 includes a closing connecting rod 13. The front end of the closing connecting rod 13 is provided with a groove for connecting to the outer tube 10, and the rear end is provided with a connecting rod connection 133 for connecting to the electric cylinder push rod 51. The rear end of the groove is provided with an outer tube through hole 132. The inner walls on both sides are symmetrically provided with gun core slots 131. A gun core card 12 is inserted into the gun core slot 131. The rear end of the outer tube 10 passes through the gun core card 12 and the outer tube through hole 132. A closing compression spring 11 is sleeved on the outer wall of the rear end of the outer tube 10. The closing compression spring 11 is disposed between the compression cavity 41 and the gun core card 12.

[0029] The electric cylinder push rod 51 is connected to the connecting rod 133 by a wing screw 14. When the electric cylinder 6 is de-energized, the wing screw will turn out and return to its initial state, ensuring that the jaws 30 can also return to their initial state after the electric cylinder 6 is de-energized.

[0030] The bracket 4 has a fixing ring 5 at its rear end, and the electric cylinder 6 is fixed on the fixing ring 5. The fixing ring 5 is fixed on the bracket 4 through the electric cylinder mounting hole 42 and screws.

[0031] A pressure sensor 32 is provided on each side of the rear end of the anvil 31 at the hinge, and the pressure sensor 32 is controlled and connected to the circuit board 3.

[0032] The circuit board 3 is provided with a retraction trigger 21 connected to the retraction button 2, a forward trigger 22 connected to the excitation link 9, a motion chip 24 connected to the pressure sensor 32, and an electric cylinder connection line connector 23 connected to the electric cylinder 6 via a connection line 52.

[0033] Before use, such as Figure 10 As shown, the electric cylinder 6 is initially in a standby state; during use, as... Figure 11 As shown, when the safety button 8 is released and the activation button 7 is pressed, the forward trigger 22 of the control circuit board 3 is activated, driving the electric cylinder to push the rod 51 forward, which in turn moves the closing rod 13 forward. The closing rod 13 moves the outer tube 10 forward and is buffered by the compression spring. The outer tube 10 pushes forward to press the abutment seat 31, causing the jaws 30 to close. The pressure sensor 32 contacts the tissue, and the closing angle is automatically determined by the analysis of the motion chip 24. When the tissue is about to be clamped, the electric cylinder 6 is controlled to move slowly to ensure accurate clamping of the tissue and prevent the tissue from slipping. This achieves the effect of free adjustment of the closing angle of the jaws 30. When retracting the blade, the retracting button 2 is pressed, activating the retracting trigger 21, which controls the electric cylinder to push the rod 51 back, moving the closing rod 13 backward and the outer tube 10 backward. The retraction of the outer tube 10 causes the jaws 30 to open.

[0034] The beneficial effects of the above-mentioned structure of this utility model are as follows: The electric closing forceps oral endoscope stapler provided by this utility model uses an electric cylinder to drive the closing component to push the outer tube to move in a stable reciprocating motion, thereby realizing the function of electric closing and opening of the jaws. Electric clamping is more labor-saving, intelligent and convenient. Moreover, the jaw closing angle can be freely adjusted, the clamping force can be adjusted, and the opening and closing can be precisely controlled. At the same time, the safety button and the blade retraction button ensure that there is no accidental triggering, thus improving the safety and reliability of the product.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
