Description

Technical Field

[0001] This utility model relates to the field of hemostatic forceps, and in particular to a separation hemostatic forceps with shearing function. Background Technology

[0002] In many open surgeries, especially those involving blood vessels, hemostatic forceps are typically used to clamp the blood vessels, forceps and needle holders are used together to complete the suturing, and finally, scissors are used to trim any excess sutures.

[0003] During surgery, it can be observed that various instruments such as forceps, needle holders, and scissors are used, and the need for personal control of these instruments can obstruct the surgeon's field of vision. Therefore, the design of hemostatic forceps with a cutting edge can reduce the use of other surgical instruments, thereby reducing obstruction in the surgeon's field of vision.

[0004] For example, utility model CN219480215U discloses a multifunctional hemostatic forceps, including a forceps body formed by the intersection of forceps arm one and forceps arm two. The forceps head of the insert is divided into a cutting part and a biting part, wherein the cutting part is close to the intersection point of the insert, and the biting part is located at the end of the forceps head. Symmetrical cutting edges are provided on the lower side of the intersection point of forceps arm one and forceps arm two, and the cutting edges are staggered to form a cutting edge. An arc-shaped rod is provided in the middle of forceps arm one, with the intersection point of forceps arm one and forceps arm two as the center. A through hole is provided on forceps arm two, corresponding to the arc-shaped rod, and the arc-shaped rod is sleeved in the through hole. A screw hole is provided on the side of the through hole, and a locking knob is installed in the screw hole. This solution designs the cutting edge between the gill and the teeth, which can achieve the above purpose.

[0005] However, in the aforementioned patent, the blade design has a relatively narrow width, only the same as the width of the pliers head. The blade can only fully close for cutting when the pliers head is closed, which may result in poor cutting performance for thinner objects. Furthermore, the patent uses a locking bar and locking tooth structure, requiring the handle to be pressed down and two fingers to separate the finger rings during closing and opening, making the operation relatively cumbersome. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology, which has a relatively narrow blade structure design, only the same width as the pliers head, and the blade can only be fully closed for cutting when the pliers head is closed. When cutting, the cutting effect may be poor for thinner objects. Therefore, this utility model provides a separation hemostat with cutting function.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A hemostatic forceps with cutting function includes a first forceps arm and a second forceps arm. The first forceps arm and the second forceps arm are each provided with a gill portion, a blade portion and a forceps head that are positioned opposite each other. The gill portions of the first forceps arm and the second forceps arm are rotatably connected by a pivot pin. The blade portion is located between the gill portion and the forceps head and is close to the gill portion. The blade portion protrudes relative to the inner surface of the forceps head. The forceps head is bent toward one side of the first forceps arm and the second forceps arm.

[0009] Furthermore, as the first and second clamp arms approach each other, the cutting edges of the first and second clamp arms have an overlap area of ​​more than 50% before the clamp heads come into contact.

[0010] Furthermore, the cutting edge has a triangular structure, divided into a main body, a beveled transition section, and a cutting edge. The two ends of the beveled transition section are connected to the main body and the cutting edge, respectively, and the bevel of the cutting edge is parallel to the bar of the pliers head.

[0011] Furthermore, the bottom of the main body is a plane, the bottom of the inclined transition part and the cutting edge part are inwardly concave curved surfaces, and the two cutting edges of the second clamp arm are located inside the cutting edge part of one cutting edge part, with the end of the cutting edge part of one cutting edge part facing the plane of the main body part of the other cutting edge part.

[0012] Furthermore, the sloped transition portion is inclined towards the bottom.

[0013] Furthermore, the first and second clamp arms are also provided with locking structures positioned opposite each other. The locking structures are rack-shaped with teeth on one side, and the teeth of the locking structures of the first and second clamp arms cooperate with each other.

[0014] Furthermore, the first and second clamp arms are also provided with finger buckles positioned opposite each other, and the locking structure is positioned close to the finger buckles.

[0015] Furthermore, the bending angle of the clamp head is within the range of 0 degrees to 180 degrees.

[0016] Furthermore, the length of the clamp head is within the range of 2mm-40mm.

[0017] Furthermore, the length of the entire first and second clamp arms is within the range of 90mm to 300mm.

[0018] Furthermore, the gills are located at the end of the first and second pincers near the head of the pincers.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] (1) The present invention sets the blade to be at a certain angle relative to the head of the clamp, and the blade protrudes from the inner surface of the head of the clamp, so that the blade can make contact and cut before the head of the clamp makes contact, which can meet the cutting of different thicknesses; and the blade is close to the gill, thus providing greater cutting force, which provides convenience for doctors during the operation and makes cutting work more labor-saving.

[0021] (2) The length of the forceps head of this utility model is designed in multiple styles from 2mm to 40mm, which can reduce the impact on the doctor's field of vision due to the excess forceps head during actual operation; the overall length of the separation hemostatic forceps is designed between 120mm and 350mm, which can generate greater force for cutting the target at the front edge or for clamping the object with the forceps head, providing convenience for the doctor's operation. Secondly, when the doctor needs to perform a deeper operation, it can provide an effective length to ensure that the forceps can reach the surgical site.

[0022] (3) The locking structure provided by this utility model is a toothed structure, which locks based on the tooth pattern. During the opening and closing process, only two fingers are needed to apply force to complete the opening and closing operation, which can reduce the doctor's operation during opening and closing and facilitate the doctor's surgery.

[0033] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0034] Example 1

[0035] like Figure 1 and Figure 2As shown, this embodiment provides a separation hemostat with cutting function, including a first clamp arm 1 and a second clamp arm 2. Both the first clamp arm 1 and the second clamp arm 2 are provided with gills 3, blades 4 and clamp heads 5 positioned opposite each other. The gills 3 of the first clamp arm 1 and the second clamp arm 2 are rotatably connected by a pivot pin. The gills 3 are located at the end of the first clamp arm 1 and the second clamp arm 2 closer to the clamp head 5. The blades 4 are located between the gills 3 and the clamp head 5 and are close to the gills 3. The clamp head 5 has teeth on one side.

[0036] The blade 4 protrudes from the inner surface of the jaw head 5; the jaw head 5 is bent toward the first jaw arm 1 and the second jaw arm 2.

[0037] In this design, the blade 4 is positioned between the gill section 3 and the clamp head 5, and as close to the gill section 3 as possible. Based on the lever principle, this provides the doctor with more effort-saving operation. The blade 4 protrudes from the inner surface of the clamp head 5, and the bevel of the blade is parallel to the rod of the clamp head 5. Furthermore, the blade 4 is designed to be at a certain angle to the clamp head 5. As the first clamp arm 1 and the second clamp arm 2 approach each other, the blades 4 of the first clamp arm 1 and the second clamp arm 2 have an overlap area of ​​more than 50% before contact with the clamp head 5. This ensures that the blade 4 can make contact and cut earlier than the clamp head, thus completing the cutting of small tissues.

[0038] Specifically, such as Figure 3 As shown, in this embodiment, the blade 4 has a triangular structure, which is divided into a main body 401, a beveled transition part 402 and a cutting edge part 403. The two ends of the beveled transition part 402 are connected to the main body 401 and the cutting edge part 403 respectively. The bevel of the cutting edge part 403 is parallel to the bar of the pliers head 5.

[0039] The bottom of the main body 401 is flat, while the bottom of the beveled transition portion 402 and the cutting edge portion 403 are inwardly concave curved surfaces 404. Within the two cutting edges 4 of the first clamp arm 1 and the second clamp arm 2, the end of the cutting edge portion 403 of one cutting edge 4 is opposite to the flat surface of the main body 401 of the other cutting edge 4. The beveled transition portion 402 is inclined towards the bottom.

[0040] In addition, in this design, the cutting edge 403 is placed closer to the gill 3. According to the lever principle, a force point with a smaller lever arm can apply a larger force to the target object, thus making it easier for doctors to cut during the operation.

[0041] The bending angle α of the forceps head 5 can be designed in multiple styles from 0° to 180°, which can facilitate the operation of doctors according to the actual surgical site and procedure. The length of the forceps head is designed in multiple styles from 2mm to 40mm, which can reduce the impact of the excess forceps head on the doctor's field of vision during actual operation.

[0042] Meanwhile, the forceps are designed in multiple lengths ranging from 120mm to 350mm. Firstly, based on the lever principle, when the handle length increases, a greater force can be generated on the front blade 4 to cut the target or the forceps head to grasp the object when the same force is applied, providing convenience for doctors. Secondly, when doctors need to perform deeper surgeries, it can provide an effective length to ensure that the forceps can reach the surgical site.

[0043] Preferred, such as Figure 4 As shown, the first clamp arm 1 and the second clamp arm 2 are also provided with locking structures 7 that are positioned opposite each other. The locking structure 7 is rack-shaped and has teeth on one side. The teeth of the locking structures 7 of the first clamp arm 1 and the second clamp arm 2 cooperate with each other.

[0044] The first clamp arm 1 and the second clamp arm 2 are also provided with finger buckles 6 positioned opposite each other, and the locking structure 7 is positioned close to the finger buckles 6.

[0045] That is, the locking structure 7 uses several locking teeth to lock together, and opening and closing can be completed by controlling the movement of the ring with only two fingers, which can effectively reduce the doctor's operation.

[0046] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
