Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an adjustable hemostat. Background Technology

[0002] A hemostat is a surgical instrument that clamps blood vessels to stop blood flow. Its working principle involves the clamping jaws to grasp tissues and blood vessels. When a medical professional holds the handle of the hemostat and applies pressure, the two jaws close, applying pressure to the clamped blood vessel or tissue, thereby blocking blood flow and achieving hemostasis. A published Chinese patent, application number 202022118334.2, entitled "A Split-Type Toothed Hemostat for Surgical Use," while allowing for easy manual assembly and disassembly, presents a challenge during surgery. Since the blood vessel or tissue to be clamped may be within the surgeon's line of sight at any angle, the surgeon must adjust their fingers, wrist, and forearm to find the appropriate clamping angle, aligning the clamped vessel or tissue in an awkward and strenuous manner. This process not only causes discomfort to the surgeon's hands, requiring a period of relief, but also increases the time needed for hemostasis, leading to prolonged treatment time and increased bleeding. Utility Model Content

[0003] In view of this, the purpose of this application is to provide an adjustable hemostat that solves the problem in the prior art where doctors use hemostats with awkward postures, leading to prolonged treatment time and increased bleeding.

[0004] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0005] An adjustable hemostatic forceps includes: a handle and a clamp handle that are rotatably connected, wherein one end of the handle and one end of the clamp handle are each connected to a clamp tip and the two clamp tips cooperate with each other, and an adjuster for adjusting the angle is connected to the middle of the clamp tip.

[0006] Furthermore, the pliers tip includes a clamping section and a fixing section rotatably connected via the adjuster, and the two fixing sections are respectively connected to the pliers handle and the grip.

[0007] Furthermore, the adjuster includes a rotating shaft, a connecting plate, a locking device, and a drive rod. The connecting plate is connected to the fixed section via the rotating shaft. The two ends of the drive rod are respectively connected to the connecting plate and the clamping section. The locking device is connected between the rotating shaft and the drive rod.

[0008] Furthermore, the regulator includes a one-way wheel, and the one-way wheel is provided with a ratchet and pawl inside.

[0009] Furthermore, a return spring is connected to the side of the grip and the pliers that are close to each other.

[0010] Furthermore, a connecting segment is connected between the handle and the pliers tip, and a mating segment is connected between the handle and another pliers tip. The connecting segment passes through the mating segment and is rotatably connected to the mating segment.

[0011] Furthermore, one of the fixed segments is connected to the connecting segment, and the other fixed segment is connected to the mating segment.

[0012] Based on the above technical features, the beneficial effects of this application are as follows: by setting an adjuster to adjust the angle of the forceps tip, doctors can operate in a more normal and comfortable posture as much as possible, so as to ensure that the blood vessel or tissue to be clamped can be aligned at the appropriate angle, reduce discomfort in the doctor's hands and arms, shorten the hemostasis time and reduce the amount of bleeding, and ensure that the treatment is completed quickly and accurately.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Example

[0022] Please refer to the above as well. Figures 1-6The embodiments of this application provide an adjustable hemostatic forceps, which relates to the field of medical device technology. The device includes: a handle 5 and a handle 4 rotatably connected. One end of the handle 5 and one end of the handle 4 are both connected to a forceps tip 1 and the two forceps tips 1 cooperate with each other. An adjuster 2 for adjusting the angle is connected to the middle of the forceps tip 1. It should be noted that in this embodiment, the handle 5 is provided for the medical personnel to hold, the forceps tip 1 is used to clamp blood vessels or tissues in the patient's body, the handle 4 is used to connect the forceps tip 1 and the handle 5, and the adjuster 2 is used to adjust the angle of the forceps tip 1. That is, the adjuster 2 divides the forceps tip 1 into two segments, which are connected to each other and can change the angle. When the blood vessel or tissue to be clamped is located in a difficult angle of view, by using the adjuster 2 to adjust the angle of the forceps tip 1, the doctor can use a more normal and comfortable posture to operate, so as to ensure that the blood vessel or tissue to be clamped can be aligned at a suitable angle, reduce the duration of discomfort in the doctor's hands and arms, shorten the time for rest or relief, and ensure that the treatment is completed quickly. This embodiment solves the problem of prolonged treatment time caused by the doctor's strange posture when using hemostatic forceps in the prior art.

[0023] Preferably, in the initial state, the pincer tip 1 is arc-shaped.

[0024] Preferably, the end of the forceps tip 1 away from the forceps handle 4 is connected to an auxiliary section, the angle between the auxiliary section and the forceps tip 1 is 60 degrees, and it is used to clamp the tissue; compared with traditional hemostatic forceps, the angle is smaller, and the clamping of tissue is more precise.

[0025] Furthermore, the forceps tip 1 includes a clamping section 11 and a fixing section 12 rotatably connected by an adjuster 2. The two fixing sections 12 are respectively connected to the forceps handle 4 and the grip 5. The adjuster 2 divides the forceps tip 1 into the rotatably connected clamping section 11 and fixing section 12. By manually rotating the clamping section 11 or the fixing section 12, the angle between the clamping section 11 and the fixing section 12 can be changed, thereby making it easier for doctors to clamp deep tissues or tissues that are obstructed.

[0026] Furthermore, the adjuster 2 includes a rotating shaft 8, a connecting plate 9, a locking device 10, and a drive rod 7. The connecting plate 9 is connected to the fixed section 12 via the rotating shaft 8. The two ends of the drive rod 7 are connected to the connecting plate 9 and the clamping section 11, respectively. The locking device 10 is connected between the rotating shaft 8 and the drive rod 7. Specifically, the rotating shaft 8, connecting plate 9, locking device 10, and drive rod 7 are connected to form the adjuster 2. The rotating shaft 8 and connecting plate 9 are coaxially and fixedly connected. The rotating shaft 8 is connected to the fixed section 12. The clamping section 11 is connected to the rotating shaft 8 via the drive rod 7. The drive rod 7 is connected to the rotating shaft via the connecting plate 9. By manually rotating the clamping section 11 or the fixed section 12, the drive rod 7 changes angle around the rotating shaft 8, thereby adjusting the angle between the clamping section 11 and the fixed section 12. Furthermore, by setting the locking device 10 between the rotating shaft 8 and the drive rod 7 to lock the angle between the clamping section 11 and the fixed section 12, the normal operation of the treatment work is ensured after the selected angle is reached.

[0027] Furthermore, the adjuster 2 includes a one-way rotating wheel, inside which a ratchet and pawl are installed. The ratchet and pawl configuration ensures that the clamping section 11 can only rotate in one direction around the fixed section 12, allowing angle adjustment even when the angle does not increase during operation. Specifically, before operation, if the angle is too large, the clamping section 11 is rotated around the fixed section 12 to re-determine the angle. Preferably, if the clamping section 11 is located within the fixed section 12, the rotation of the clamping section 11 will not be interfered with, while ensuring the normal operation of the clamping procedure.

[0028] Furthermore, a return spring 6 is connected to the side of the handle 5 that is close to the forceps handle 4. The return spring 6 enables the two handles 5 to automatically move away from each other, eliminating the need for the doctor to manually open the scissor handles 5 and reducing the doctor's operating steps.

[0029] Furthermore, such as Figure 4 As shown, a connecting section 3 connects the handle 5 to the jaw tip 1, and a mating section 13 connects the handle 4 to the other jaw tip 1. The connecting section 3 passes through the mating section 13 and is rotatably connected to it. One fixed section 12 is connected to the connecting section 3, and another fixed section 12 is connected to the mating section 13. Through the mutual cooperation of the connecting section 3 and the mating section 13, the normal operation of clamping and releasing can be ensured.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
