Description

Technical Field

[0001] This utility model relates to the field of medical devices, and more specifically, to a rapid tissue separation forceps for liver, gallbladder and pancreas surgery. Background Technology

[0002] In hepatobiliary and pancreatic surgery, tissue dissection is a crucial step, directly impacting the success of the operation and the patient's postoperative recovery. With continuous advancements in medical technology, tissue dissection forceps, as key surgical instruments, are constantly evolving and improving. Currently, tissue dissection forceps used in hepatobiliary and pancreatic surgery are diverse in design and function, aiming to improve surgical efficiency and reduce surgical trauma.

[0003] In hepatobiliary and pancreatic surgery, while the scissor-like incision design improves dissection speed to some extent, its sharp blade also increases the risk of damaging the patient's tissues. Especially when dealing with critical structures such as blood vessels and nerves, improper operation can lead to severe bleeding or nerve damage, even endangering the patient's life. Furthermore, the scissor-like incision can easily generate tearing forces during tissue dissection, leading to tissue damage and poor postoperative healing.

[0004] Therefore, we have made improvements to this and proposed a rapid tissue separation forceps for hepatobiliary and pancreatic surgery. Utility Model Content

[0005] The purpose of this invention is to address the fact that while the existing scissor-style opening design improves the separation speed to some extent, its sharp blade also increases the risk of damaging the patient's body tissues.

[0006] In order to achieve the above-mentioned objectives, this utility model provides a rapid tissue separation forceps for hepatobiliary and pancreatic surgery to improve the above-mentioned problems.

[0007] The application is as follows:

[0008] The clamp body consists of two staggered clamp bars, with a hinge bar that flips to both sides on the side of the clamp body away from the handle end, and an airbag is provided between the hinge bars;

[0009] A fan-shaped compression bag that draws gas into the airbag through a connecting tube is fixed between the two clamps of the clamp body.

[0010] When the angle between the two clamp bars of the clamp body changes, the connection point between the airbag and the hinge bar is on the same straight line as the hinge point of the hinge bar, and the two hinge bars are parallel to each other.

[0011] Preferably, the connection point between the airbag and the hinge rod is located in the direction from the hinge point of the hinge rod towards the opening, and the distance is one-third of the length of the hinge rod.

[0012] Preferably, the two clamp bars of the clamp body are staggered, that is, the two hinged rods are also staggered.

[0013] Preferably, one side of the clamp body is bent outward to form a gripping part, and the rotation point of the clamp body is located on a single clamp bar, at a position where the length from the opening end to the gripping part is one-sixth of the length of the clamp bar.

[0014] Preferably, limiting rings are provided on both sides of the rotation point of the clamp body to restrict the offset of the connecting pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] To address the issue that while the existing scissor-style opening design improves separation speed to some extent, its sharp blades also increase the risk of damaging the patient's tissues, this application adds a hinge rod at the scissor-style opening position. Through the cooperation of the hinge rod, the fan-shaped compression bag, and the airbag, the displacement of the hinge point of the hinge rod is compensated by the filling of the airbag, ensuring that the airbag keeps the two hinge rods parallel at all times. This achieves the use of the same scissor-style structure, avoiding damage to the patient's tissues during the opening and closing process. Attached Figure Description

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] As described in the background section, while the scissor-like opening design improves the separation speed to some extent, its sharp blade also increases the risk of damaging the patient's body tissues.

[0025] To address this technical problem, this invention provides a rapid tissue separation forceps for hepatobiliary and pancreatic surgery. The forceps are designed to open their ends in parallel, ensuring both rapid tissue separation and minimal damage to the patient's tissues, thus preventing a worsening of their condition.

[0026] For details, please refer to Figure 1 , Figure 2 and Figure 3 A rapid tissue separation forceps for hepatobiliary and pancreatic surgery specifically includes:

[0027] The clamp body 1 consists of two staggered clamp bars. The side of the clamp body 1 away from the handle end is hinged to a hinge bar 2 that flips to both sides. An airbag 4 is provided between the hinge bars 2. The clamp body 1, composed of staggered clamp bars, allows the user to open and close the top of the clamp body 1 by pulling with their fingers, thereby gradually expanding the space between the two hinge bars 2. This enables the separation of partially adhered tissues, allowing the user to separate the tissues for surgery in a short time, ensuring the patient's rescue time and health.

[0028] A fan-shaped compression bag 3 is fixed between the two clamps of the clamp body 1, which draws gas into the air bag 4 through the connecting tube 34. The opening and closing of the clamps causes the space and volume of the fan-shaped compression bag 3 to change after being squeezed, causing the gas in the fan-shaped compression bag 3 to flow into the air bag 4. The angle between the clamps at the open end of the clamp body 1 gradually increases to complete the distance required for separation. At the same time, after the air bag 4 is filled with gas, it expands the volume of the vertical space between the tissues, preventing secondary adhesion of the tissues and effectively ensuring the separation effect of the patient's tissues.

[0029] When the angle between the two clamp bars of the clamp body 1 changes, the connection point between the airbag 4 and the hinge point of the hinge bar 2 is on the same straight line, and the two hinge bars 2 are parallel to each other. As the distance between the hinge bars 2 gradually increases, the hinge bars 2 will gradually bend inward. However, as the airbag 4 gradually fills in, the part filled by the airbag 4 gradually fills the gap caused by the displacement, so that the two hinge bars 2 are always set in parallel. In the end, the hinge bars 2 are separated from the previous scissor-like opening and closing, which avoids injury to the patient or a decrease in the success rate of the operation. Instead, the hinge bars 2 gradually separate parallel to the tissue end, preventing secondary damage.

[0030] For an example, please refer to... Figure 1 , Figure 2 and Figure 3A rapid tissue separation forceps for hepatobiliary and pancreatic surgery has a connection point between the airbag 4 and the hinge rod 2 located at the hinge point of the hinge rod 2 in the direction of opening, and the distance is one-third of the length of the hinge rod 2. By fixing the point of this length, the airbag 4 can allow the hinge rod 2 to expand a greater distance when filled with less gas, making the overall operation smoother.

[0031] The two clamp bars of the clamp body 1 are misaligned, that is, the two hinged rods 2 are also misaligned. Since the hinged rods 2 are not on the same horizontal plane, in order to maintain a relatively ideal separation effect, the separation clamp needs to be tilted at the position where the patient needs to separate the tissue during use.

[0032] One side of the clamp body 1 is bent outward to form a gripping part. The rotation point of the clamp body 1 is located on a single clamp bar, at a position where the length of the gripping part is one-sixth of the length of the clamp bar from the open end. Since the length of the gripping part of the clamp body 1 is greater than the length of the scissor edge, it makes it easier for the operator to grip the clamp while slowing down the lever action at the port, thereby increasing the operator's reaction time and operational accuracy.

[0033] Limiting rings 5 ​​are provided on both sides of the rotation point of the clamp body 1 to limit the displacement of the connecting pipe 34. The position of the connecting pipe 34 is limited by the limiting rings 5 ​​to prevent damage to the connecting pipe 34 during the crossing of the clamp body 1.

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
